21 # Version __VERSION__, __RELEASEDATE__
22 #------------------------------------------------------------------------
24 * Added BackupPC::Xfer::Protocol as a common class for each Xfer
25 method. This simplifies some of the xfer specific code.
26 Implemented by Paul Mantz.
28 * Added FTP xfer method, implemented by Paul Mantz.
30 * Added BackupPC::Xfer module to provide a common interface to the
31 different xfer methods. Implemented by Paul Mantz.
33 * Moved setting of $bpc->{PoolDir} and $bpc->{CPoolDir} after the
34 config file is read in BackupPC::Lib. Fix proposed by Tim Taylor
37 * Create $TopDir and related data directories in BackupPC_dump
38 prior to hardlink test. Requested by Les Stott.
40 * Modified lib/BackupPC/CGI/RSS.pm to replace \n with \r\n in the RSS
41 http response headers. Patch submitted by Thomas Eckhardt.
43 * Modified bin/BackupPC_archive to allow the archive request file
44 name to contain spaces and dashes, requested by Tim Massey.
46 * Fix to configure.pl for --no-fhs case to initialize ConfigDir
47 from Dan Pritts. Also changed perl path to #!/usr/bin/env perl.
49 * Modified bin/BackupPC_archiveHost to shell escape the output file
50 name. That allows it to contain spaces and other special characters.
51 Requested by Toni Van Remortel.
53 * Added --config-override to configure.pl, allow config settings to be
54 set on the command line. Proposed by Les Stott and Holger Parplies.
56 * Minor updates to lib/BackupPC/Lang/fr.pm from Nicolas STRANSKY
59 * Minor updates to lib/BackupPC/Lang/de.pm from Klaus Weidenbach.
61 * lib/BackupPC/Xfer/Smb.pm now increments xferErrCnt on NT_STATUS_ACCESS_DENIED
62 and ERRnoaccess errors from smbclient. Reported by Jesús Martel.
64 * Modified bin/BackupPC_sendEmail to not send any per-client email if
65 $Conf{BackupsDisable} is set.
67 #------------------------------------------------------------------------
68 # Version 3.1.0, 25 Nov 2007
69 #------------------------------------------------------------------------
71 * Fixed config editor bug for case where override is unchecked on
72 an array where the current array is shorter than the main config's
75 * Fixed missing close quote in BackupPC_archiveHost reported by Franky
78 * Replaced "$BinDir/.." with $bpc->InstallDir() for path to BackupPC
79 docs, mentioned by Kenneth Porter.
81 * Moved default of $Conf{IncrLevels} from lib/BackupPC/Storage/Text.pm
82 to lib/BackupPC/Lib.pm (after the merge of the config files). This
83 fixes a bug that caused $Conf{IncrLevels} to get over-ridden if it
84 was only defined in the main config file. Reported by John Rouillard.
86 * Fixed the completion status message in BackupPC_dump so that missing
87 error counts appear as 0, rather than empty. Reported by Bill.
89 * Changed lib/BackupPC/Xfer/RsyncFileIO.pm to only increment the error
90 count when the md4 checksum fails on the second phase, not the first.
91 Reported by Adrian Bridgett.
93 * Updated a comment in config.pl about BackupPC_nightly, reported by
96 * Modified lib/BackupPC/CGI/Restore.pm to ensure that the list of hosts
97 presented for direct restore do have direct restore enabled. Reported
100 * Modified lib/BackupPC/CGI/RestoreFile.pm to replace \n with \r\n in
101 the restore http response headers. Patch submitted by Thomas Eckhardt.
103 #------------------------------------------------------------------------
104 # Version 3.1.0beta1, 21 Oct 2007
105 #------------------------------------------------------------------------
107 * When there is an existing partial, a new partials is only saved
108 if it has more files than the existing partial. Requested by
111 * Fixed handling of $Conf{BackupFilesExclude} for tar XferMethod.
112 Patch supplied by Frans Pop.
114 * Fixed numeric column sorting in host summary table, reported by
117 * Fixed host CGI editor so it creates the new host's config.pl file
118 using the lower-case host name, since host names are mapped to
119 lower case when they are read from the hosts file. Reported by
122 * Applied documentation patches from Frans Pop. Also updated
123 Pod::Html to improve documentation formatting.
125 * Added Polish translation from Semper.
127 * Fixed BackupPC_nightly reporting of repeated pool file hashes.
129 * Add run-time check that IO::Dirent is functioning correctly,
130 reported by Doug Lytle.
132 * Added comment to Cmd settings in conf/config.pl that they are
133 not executed by a shell, as suggested by Erik van Linstee.
135 * Added undefIfEmpty => 1 to lib/BackupPC/Config/Meta.pm for
136 RsyncRestoreArgs, TarClientRestoreCmd and SmbClientRestoreCmd
137 so that restores can be disabled by clear these fields in the
138 CGI editor. Patch supplied by Stephen Joyce
140 * Replaced the FAQ link with Wiki in the navigation bar and added
141 mention of the Wiki to the documentation. Since these navigation
142 bar links are specified in the config file, upgrades will keep
143 the old FAQ link. The FAQ opening page will have a prominent
146 #------------------------------------------------------------------------
147 # Version 3.1.0beta0, 3 Sep 2007
148 #------------------------------------------------------------------------
150 * Added new script BackupPC_archiveStart that allows command-line
151 starting of archives. Based on script written by Sergey Kovzik,
152 which in turn was based on an earlier version by Holger Parplies.
154 * Added Simplified Chinese CGI translation from Youlin Feng,
155 plus fixed a couple of cases where utf8 share names were
156 not displayed correctly.
158 * Added sorting by column feature to host summary table in CGI
159 interface. Implemented by Jeremy Tietsort.
161 * Added optional support for IO::Dirent which allows inode information
162 to be extracted from the dirent directory structure. This allows
163 BackupPC to order some directory operations by inode, which on
164 some file systems (eg: ext3) can results in a 20-30% performance
165 gain. On other file systems there is no real improvement. This
166 optimization is turned on automatically if IO::Dirent is installed.
168 * Added some performance improvements to BackupPC::Xfer::RsyncFileIO
169 for the case of small files with cached checksums.
171 * Added check to BackupPC at startup that $TopDir can support
172 hardlinks. Also added check to BackupPC_dump that a hardlink
173 below $TopDir/pc/HOST can be made to below $TopDir/cpool.
174 Also added the need for a hard-link capable file system to
175 the documentation. Suggested by Nils Breunese.
177 * Added FreeBSD init.d file provided by Gabriel Rossetti.
179 * Added -l and -L options to BackupPC_tarCreate so that
180 provide a file list (without creating the archive).
183 * Made the default charset for BackupPC_zipCreate cp1252, which
184 appears to work correctly with WinZip. Unfortunately there is
185 no clear standard for charset encoding in zip files.
187 * Added support so that pre-3.0 backups with non-utf8 charsets
188 can be viewed and restored correctly. A new config variable
189 $Conf{ClientCharsetLegacy} specifies the charset used to
190 encode file names in legacy backups. This is only relevant
191 if you are trying to view or restore a backup made with
192 BackupPC 2.x and some of the file names have non-ascii
195 * Added setting of the environment variable BPC_REQUSER to
196 the requesting user name in BackupPC prior to fork(), so
197 each child process inherits the value. Submitted by
200 * Fixed bug in rsync incrementals that happens on particular
201 file names when a file being backed up fails in both rsync
202 phases. Reported by Dan Smisko.
204 * Fixed single-restore file name charsets for IE, reported by
207 * Fixed makeDist so that the --config-dir option to configure.pl
208 works correctly. Reported by Randy Barlow, Tony Shadwick and others.
210 * Removed ConfDir from config editor (since it is hardcoded in
211 lib/BackupPC/Lib.pm). Also made TopDir and LogDir only visible
212 if useFHS (for non-FHS they are hardcoded in lib/BackupPC/Lib.pm).
214 * Applied patch from Holger Parplies that fixes cleanup of early abort
217 * Applied small patch from Sergey to lib/BackupPC/Xfer/Tar.pm that makes
218 it ignore "socket ignored" error on incrementals.
220 * Applied small patch from Sergey to bin/BackupPC_archiveHost.
222 * Changed BackupPC_sendEmail so that summary admin email doesn't
223 include errors from hosts that have $Conf{BackupsDisable} set.
224 Reported by James Kyle. Also, per-user email is now disabled
225 when $Conf{BackupsDisable} is set.
227 * Added RsyncdUserName to the config editor. Reported by Vicent Roca Daniel.
229 * $Conf{IncrLevels} is now defaulted if it is not defined.
231 * configure.pl clears $Conf{ParPath} if it doesn't point to a valid
234 * Added documentation for BackupPC_tarPCCopy, including use of -P option
235 to tar suggested by Daniel Berteaud.
237 * Config editor now removes white space at start of exec path.
238 Reported by Christoph Iwasjuta.
240 * CgiDateFormatMMDD == 2 gives a YYYY-MM-DD format for CGI dates,
243 #------------------------------------------------------------------------
244 # Version 3.0.0, 28 Jan 2007
245 #------------------------------------------------------------------------
247 * BackupPC_sendEmail now correctly sends admin email if backups
248 were skipped because the disk was too full, reported by Dan
251 * BackupPC_Admin now uses $Conf{UmaskMode}, so config.pl files
252 written by the editor have more restrictive permissions.
253 Reported by Tim Massey.
255 * Host summary now shows active backups on disabled hosts,
258 * Fixed host LOG link and LOG list order, reported by Tim Massey.
260 * Moved Encode.pm version check to start of configure.pl so it
261 produces a useful error message if Encode.pm is too old.
263 * Fixed hrefs to configuration documentation to handle changes
264 in the way perl generates the anchors. Reported by Philip
267 * Host name links in LOG files now allow "." in the host name.
268 Reported by Jean-Michel Beuken.
270 * Fixes to lib/BackupPC/Xfer/Tar.pm for tar 1.16: allow 1
271 (ie: 256) as a successful exit status and match "Total
272 bytes read" message for restores. First reported by
273 Torsten Sadowski and debugged by Ralf Gross and Holger
276 #------------------------------------------------------------------------
277 # Version 3.0.0beta3, 3 Dec 2006
278 #------------------------------------------------------------------------
280 * Removed default paths from conf/config.pl so configure.pl will
281 determine the correct ones at install time. Avoids problem of
282 the config editor complaining about bad executable paths the
283 first time you use it.
285 * Changed first byte of compressed files with rsync checksums appended
286 to 0xd7 to allow correct protocol_version >= 27 md4 checksums to be
287 written. Old cached checksum files have a first byte 0xd6 and are
288 now considered to be uncached. They will be automatically updated
289 as needed. This avoids the cached checksum warnings in beta2.
291 * BackupPC_tarPCCopy now handles all file types correctly. Reported
294 * Fixed BackupPC_nightly to finish pending deletes before renaming
297 * Fixes for rsync restore where hardlink is to file outside of the
298 top-level restore directory. Reported by George Avrunin, who helped
301 * Fixes for checksum mismatch on restore for certain file sizes.
302 Reported by George Avrunin and others.
304 * Fix for config.pl writing code to handle multi-line expressions.
305 Reported by David Relson and others.
307 * Fix for CGI editor when deleting hash entries whose keys are
308 non alphanumeric. Report by David Relson and Aaron Ciarlotta.
310 * Two fixes to configure.pl from Andreas Vögele.
312 #------------------------------------------------------------------------
313 # Version 3.0.0beta2, 18 Nov 2006
314 #------------------------------------------------------------------------
316 * Fix for final md4 digest check on rsync transfers >= 512MB when protocol
317 version >= 27 and checksums are not cached. Reported by Garith Dugmore
320 * Config Editor "Save" button is now always visible, but greyed out
321 until there are changes to save.
323 * Config editor allows other tabs to be selected when there is an
324 error, which allows you to fix an error (eg: missing binary) in
325 an exiting config file. Errors are now displayed at the top of
326 the page in addition to next to the erroneous setting.
328 * configure.pl checks version of Encode.pm. Reported by Chris Stone.
330 * Several fixes to bin/BackupPC_fixupBackupSummary from Stian Jordet.
332 * Fixed config.pl editor writing to solve bug with multi-line text
333 strings ending in newline. Reported and root caused by Les Stott
336 * Fixed error recovery case in BackupPC::PoolWrite, reported by
339 * Fixed table width in backup browsing to avoid Firefox layout anomoly,
340 provided by Jono Woodhouse.
342 * CSS file updates from Jono Woodhouse. Prior (v2) version is included
343 as BackupPC_stnd_orig.css in case people prefer the old skin.
345 * More compact host summary, including disabled host indication,
348 * New directory/file/hardlink and symlink image icons from Sean Cameron
349 and Jono Woodhouse, making directory browse more compact.
351 * BackupPC.pid is now world readable, suggested by Casper Thomsen.
353 * Reordered the Server navigation bar links, suggested by David Relson.
355 * Fixed typos in init.d/src/gentoo-backuppc, configure.pl and config.pl
356 reported by David Relson.
358 #------------------------------------------------------------------------
359 # Version 3.0.0beta1, 30 Jul 2006
360 #------------------------------------------------------------------------
362 * Fixed several Xfer charset conversions.
364 * Added some CGI utf8 conversions from Rodrigo Real and Vincent
367 * Rsync transfers now correctly handle file names with \n or \r.
369 * Host name is forced to lower case, to match 2.x.
371 * Fixed LOG file naming in BackupPC_restore and BackupPC_archive.
373 * GFK applied fr.pm corrections from Nicolas Stransky.
375 * Updated init.d/src scripts for FHS (ie: replaced __TOPDIR__/log
376 with __LOGDIR__ and __TOPDIR__/conf with __CONFDIR__). Patch
377 provided by Rodrigo Real.
379 * Added --log-dir and --conf-dir options to configure.pl.
380 Reported by Vincent Fleuranceau.
382 * Updated File::RsyncP version check in configure.pl, reported
383 by Vincent Fleuranceau. Changed File::RsyncP version to 0.64.
385 #------------------------------------------------------------------------
386 # Version 3.0.0beta0, 11 Jul 2006
387 #------------------------------------------------------------------------
389 * Added configuration and host CGI editor.
391 * Added rsync hardlink support. Requires latest version of
394 * Decoupled BackupPC_dump from BackupPC_nightly by making
395 asynchronous file linking/delete robust to race conditions.
396 Now only BackupPC_nightly and BackupPC_link are mutually
397 exclusive so only one runs at a time, and BackupPC_dump and
398 BackupPC_restore can run anytime.
400 * Added support for multi-level incrementals. In the style of dump(1),
401 the level of each incremental can be specified. Each incremental
402 backups up everything since the most recent backup of a lower level
403 (fulls are always level 0). Previous behavior was all incrementals
404 were level 1, meaning they backed up everything since the last full
405 (level 0). Default configuration is all incrementals are level 1.
407 * Server file names are now in utf8 and optional conversion
408 to/from client name charsets can be configured. All CGI pages
409 now use the utf8 charset.
411 * Backup metadata is now additionally saved to pc/HOST/nnn/backupInfo,
412 in addition to pc/HOST/backups. In case pc/HOST/backups gets trashed,
413 then a new script BackupPC_fixupBackupSummary can read the per-backup
414 metadata from pc/HOST/nnn/backupInfo and reconstruct the backups file.
415 Roberto Moreno also pointed out an early error in the CVS version.
417 * Added Storage module and Storage::Text which localizes all the
418 text data file reading/writing (eg: backups, restores, archives
419 and config.pl files). Added read verify after all write
420 operations for robustness. Additional backends (eg: SQL)
421 can be added in the future as new subclasses of the Storage
424 * Added Config module, and Config::Meta that contains meta data
425 about configuration parameters.
427 * Added RSS support from Rich Duzenbury.
429 * Translations of new 3.0 language strings from Guillaume Filion,
430 Reginaldo Ferreira, Ralph Passgang, Lieven Bridts, Guus Houtzager,
433 * Added optional checking of exit status of Dump/Restore/Archive Pre/Post
434 UserCmd, requested by Kiko Jover, Matthias Bertschy and others.
436 * For new installations configure.pl tries to comply with the file
437 system hierarchy standard, which means all the configuration files
438 below /etc/BackupPC and log files go below /var/log/BackupPC.
440 * Added Slackware init.d script from Tony Nelson.
442 * Fixed error reporting when restore/archive fail to write the
443 request file to the client directory.
445 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
447 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
448 to DumpPreUserCmd etc.
450 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
452 * Jean-Michel Beuken reported several bugs in configure.pl in CVS 3.0.0.
454 * Old backup email warnings now ignore partials requested by Samuel Bancal
456 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
457 ignores any file starting with "." in the pc directory when
458 it is generating warnings about old/unused files/directories.
460 * Applied patch from Marc Prewitt to fix host queue order.
462 * Applied Lorenzo Cappelletti's it.pm patch.
464 * Applied Wander Winkelhorst's nl.pm patch.
466 * Applied Alberto Marconi's it.pm patch.
468 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
469 BackupPC_sendEmail to fix bug reported by Dale Renton.
471 * Added fixup of $ENV{REMOTE_USER} to lib/BackupPC/CGI/Lib.pm in the
472 case of using mod_authz_ldap; patch submitted by Alain Perrier.
474 * Added env LC_ALL=C to $Conf{TarClientCmd} and $Conf{TarClientRestoreCmd}
475 to avoid locale problems, suggested by Ludovic Drolez.
477 * Changed ping output parsing to pick out average rtt time, based
478 on patch from Ron Bickers.
480 * Removed leading "./" and top-level "./" directory from
481 zip archives generated by BackupPC_zipCreate. Reported
482 by Josh (hecktarzuli).
484 * BackupPC_tarCreate and BackupPC_zipCreate now allow "@"
485 in share names. Reported by Robert Waldner.
487 * NT_STATUS_INSUFF_SERVER_RESOURCES is now a fatal error for
488 smbclient transfers, suggested by Brian Shand.
490 * Changed bin/BackupPC_archiveHost to use /bin/csh instead of
491 /bin/sh. That way any errors in the pipeline are reported
492 via the exit status, instead of just the last.
494 * Added $Conf{EMailHeaders} for additional email headers, requested
495 by Ludovic Gasc. If the Content-Type charset is set to utf8 then
496 the body of the email is sent in utf8 coding.
498 * Made shareName argument regexp checking more general to allow parens.
500 * Added some debian init.d instructions to init.d/README from
503 * Documentation updates from Richard Ames, JP Vossen, Torsten Finke.
505 #------------------------------------------------------------------------
506 # Version 2.1.2pl2, 18 Jun 2006
507 #------------------------------------------------------------------------
509 * In conf/config.pl, changed --devices to -D in $Conf{RsyncArgs}
510 and $Conf{RsyncRestoreArgs} to fix "fileListReceive failed" and
511 "Can't open .../f%2f for empty output" errors with rsync 2.6.7+.
512 Fix proposed by Justin Pessa and Vincent Ho, and confirmed by
515 * Added patch from Michael (mna.news) to ignore "file is unchanged"
516 message from tar 1.15.x during incremental backups.
518 * Fixed creation of .rsrc directories in bin/BackupPC_tarExtract
519 when used with xtar on MacOS. Reported by Samuel Bancal and
520 Matthew Radey, who helped with debugging.
522 * Fixed bug in BackupPC_tarExtract for files >8GB in size whose
523 lengths are multiples of 256. Reported by Jamie Myers and
524 Marko Tukiainen, who both helped debugging the problem.
526 * Fixed bug in lib/BackupPC/Xfer/RsyncFileIO.pm that caused
527 incorrected deleted attributes to be set in directories
528 where one of the files had an rsync phase 1 retry during
529 an incremental. Reported by Tony Nelson.
531 #------------------------------------------------------------------------
532 # Version 2.1.2, 5 Sep 2005
533 #------------------------------------------------------------------------
535 * Fixed simple but serious bug in bin/BackupPC_tarCreate that prevented
536 hardlinks being saved correctly. Debugged by Michael (mna.news)
537 with several other people.
539 * Fixed serious bug in bin/BackupPC_dump reported/debugged by Dan Niles
540 that can happen when multiple full backups are deleted after
541 $Conf{FullKeepCnt} is changed.
543 * Changed lib/BackupPC/CGI/Lib.pm so that link to "$TopDir/conf/$host.pl"
544 is displayed if it exists. Patch from Andreas Vögele.
546 * Applied daemonize patch to bin/BackupPC from:
547 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=301057
549 * It's now a fatal error if $Conf{CompressLevel} is set, but
550 Compress::Zlib is not found. Before $Conf{CompressLevel} was
551 silently set to 0, which made all the backups uncompressed.
552 That meant the user never knew if they forget to install
553 Compress::Zlib but were expecting compression to be on.
555 * Finally increased $Conf{ClientTimeout} to 72000 (20 hours).
557 * Added sleep 1 in restart() function in init.d/src/gentoo-backuppc,
558 suggested by Jon Hood.
560 * Added $DestDir to the path of the CGI image directory in configure.pl.
561 Patch submitted by Andreas Vögele.
563 * Applied extensive patch to French translation from Frederic Lehobey.
565 * Minor change to Dutch language $Lang{Pool_Stat} from Wander Winkelhorst.
567 * Minor change to French language $Lang{EMailOutlookBackupMesg} and
568 $Lang{EMailOutlookBackupSubj} from Ludovic Gasc.
570 #------------------------------------------------------------------------
571 # Version 2.1.1, 13 Mar 2005
572 #------------------------------------------------------------------------
574 * Fixed bug in top-level restore using rsync XferMethod.
575 BackupPC::View was leaving an extra leading "/" at the start
576 of top-level directories, messing up the FileList sort order.
577 Reported and debugged by Gail Edwards.
579 * Added pathCreate() to BackupPC_tarExtract so that new directories
580 are created. Required for xtar on MacOSX since the virtual resource
581 fork directories (.rsrc) are not explicitly included in the tar
582 archive - just the files below .rsrc are.
584 * Changed $host.$bkupNum.tar$fileExt.* to $host.$bkupNum.tar$fileExt*
585 in $parCmd in bin/BackupPC_archiveHost.
587 * Fixed HostSortCompare() in BackupPC to correctly sort hosts so
588 those with the oldest backups get queued first.
590 * Changed test in BackupPC_sendEmail so that directories/files
591 starting with "." in $TopDir/pc are ignored, rather than
594 * Changed BackupPC_sendEmail to include NT_STATUS_FILE_LOCK_CONFLICT
595 in check for bad outlook files.
597 * Ensure that %Status and %StatusHost are empty if requesting
598 status on hosts in lib/BackupPC/CGI/Lib.pm GetStatusInfo().
599 Fixes problem with new hosts under mod_perl.
601 * Added images/icon-hardlink.gif so that hardlinks show file type icon.
603 #------------------------------------------------------------------------
604 # Version 2.1.0pl1, 15 Aug 2004
605 #------------------------------------------------------------------------
607 * Added fix to nl.pm from Lieven Bridts.
609 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
610 writes the status and shuts down.
612 * Changed BackupPC_nightly so that it doesn't call find() if the
613 directory doesn't exist. This avoids errors in certain versions
614 of perl. Reported by Bernd Rilling.
616 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
617 Reported by Tony Nelson and Jimmy Liang.
619 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
620 reported by Thomas Tempé.
622 * Added newline to "...skipping because of user requested delay..."
623 log message in BackupPC_dump. Reported by Wayne Scott.
625 * Added read file size error checking to BackupPC_tarCreate.
626 Reported by Brandon Evans.
628 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
629 compression is toggled on/off, a compressed backup doesn't link
630 to an uncompressed pool file (and an uncompressed backup doesn't
631 link to a compressed pool file). Reported by Brandon Evans.
633 * Updated documentation with new dirvish URL and a typo from
636 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
637 for hosts that have failed backups. Reported by Simon Kuhn.
639 #------------------------------------------------------------------------
640 # Version 2.1.0, 20 Jun 2004
641 #------------------------------------------------------------------------
643 * Added Dutch translation from Lieven Bridts, with tweaks from
646 * Added PC-specific config file read in CGI/Archive.pm. Patch
649 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
650 Patch from Pete Wenzel.
652 * Cosmetic changes to PC Summary and Log file language strings from
655 * BackupPC::Lib tries to be more careful when renaming the backups
656 file to backups.old. There have been reports of backups being
657 empty, perhaps when the BackupPC data file system fills up.
658 Now backups is not renamed to backups.old if backups is empty.
660 * BackupPC now closes stderr and stdout before renaming and
661 re-opening the log file.
663 * Pre/post backup/restore/archive commands now correctly set
664 "type" to either incr/full/restore/archive, and now cmdType
665 is the type of Pre/post backup/restore/archive command.
667 * BackupPC_archive correctly terminates archive processes on
670 * Updates to BackupPC_stnd.css with absolute font sizes instead
673 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
674 also ensures the full backup is older than the maximum age
675 expected from $Conf{FullPeriod}.
677 #------------------------------------------------------------------------
678 # Version 2.1.0beta2pl1, 30 May 2004
679 #------------------------------------------------------------------------
681 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
683 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
684 since zip file formats don't support earlier dates. Reported
687 * CGI restore via zip and tar now makes sure stderr is ignored
688 when BackupPC_tarCreate and BackupPC_zipCreate are run.
689 Previously any stderr output would get mixed in the archive,
690 corrupting it. Reported by Dan Niles.
692 #------------------------------------------------------------------------
693 # Version 2.1.0beta2, 23 May 2004
694 #------------------------------------------------------------------------
696 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
697 to every share, rather than just the first, in the case where
698 they are arrays and there are multiple shares. Suggested
701 * On the phase 2 retry pass with rsync, verify the cached checksums
702 if checksum caching is turned on. This will catch the case of
703 cached checksums being incorrectly appended to the compressed
704 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
705 so that cached checksums are verified with a selectable probability.
706 Also, increased File::RsyncP version number to 0.51.
708 * configure.pl now supports an optional batch mode. Command-line
709 options are used to specify all the information that configure.pl
710 needs. This is useful for building auto-install packages.
711 Also, configure.pl now includes pod documentation, so you can do
712 "perldoc configure.pl" to see all the command-line options.
713 Suggested, tested and tweaked by Stuart Herbert for possible
716 * At each wakeup, clients are now queued based on how old the most
717 recent backup is. Clients with errors are queued first, with
718 the oldest error times going first. The rest of the clients are
719 queued next, with the clients with the oldest backup going first.
720 Previously the clients were simply queued in alphabetic order.
721 Suggested by Mike Trisko and Tony Nelson.
723 * Added config parameter $Conf{PartialAgeMax} that controls whether
724 partials are saved at all, and if so, whether the partial will be
725 ignored at the next full backup if it is too old.
727 * BackupPC_tarExtract now allows empty archives without reporting
728 an error. Reported by Don Silvia.
730 * Removed Browse Backups link from Nav Bar in Archive Info display.
731 Reported by Ralph Paßgang.
733 * Fixed documentation display for regular users. Reported by Ralph Paßgang.
735 * Status and PC Summary now work for regular users and only show
736 that user's hosts. Server general status information only appears
737 for admins. Suggested by Ralph Paßgang.
739 * Moved the last three navigation-bar links (docs, FAQ and SF) to
740 a new config parameter $Conf{CgiNavBarLinks}. This allows
741 these links to be locally configured. Based on a patch
742 submitted by Ralph Paßgang.
744 * Allow the navigation bar search box to be disabled by
745 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
746 submitted by Ralph Paßgang.
748 * Updates to de.pm from Ralph Paßgang.
750 * Made the BackupPC icon a link to the SF BackupPC project page.
752 #------------------------------------------------------------------------
753 # Version 2.1.0beta1, 4 Apr 2004
754 #------------------------------------------------------------------------
756 * The CSS definition has been removed from the config.pl file and
757 is now a separate file, BackupPC_stnd.css. A new config variable,
758 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
759 Suggested by Ender Mathias.
761 * Fixed the filling of the host name select box for admins.
762 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
763 Reported by Doug Lytle.
765 * Cleaned up warning message for restore using rsync when checksum
766 caching is on, but when file didn't have cached checksums.
768 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
769 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
771 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
772 giving a significant performance improvement. Patch submitted by
775 * Allow several BackupPC_nightly processes to run in parallel based
776 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
777 traversal of the pool, reducing the overall run time for
780 * Allow BackupPC_nightly to split the pool traversal across several
781 nightly runs. This improves the running time per night, at the expense
782 of a slight increase in disk storage as unused pool files might not
783 be deleted for a couple of days. Controller by new config setting
784 $Conf{BackupPCNightlyPeriod}.
786 #------------------------------------------------------------------------
787 # Version 2.1.0beta0, 20 Mar 2004
788 #------------------------------------------------------------------------
790 * A failed full dump is now saved as a partial (incomplete) dump,
791 provided it includes some files. This can be used for browsing,
792 restoring etc, and will also form the basis of resuming full
793 dumps. Only one partial is kept, and it is removed as soon
794 as a successful full (or a new partial) is done.
796 * Added support for resuming a full dump for rsync. The partial
797 full is kept, and to resume an incremental is done against the
798 partial, and a full is done for the rest.
800 * Added support for Rsync checksum caching. Rsync checksum are
801 appended to the compressed pool files. This means that block
802 and file checksums do not need to be recomputed on the server
803 when using rsync. Requires a patch to rsync to support fixed
804 checksum seeds. This patch is included in the cygwin-rsyncd
805 release on http://backuppc.sourceforge.net.
807 * Major addition of Archive feature from Josh Marshall. Special
808 clients can be configured to be archive targets (eg: tape drives,
809 CD-R). Any subset of the backup clients can be selected and tar
810 archives are created, optionally compressed and split and written
811 to the output device. Logs are maintained and are browsable.
813 * Major changes from Ryan Kucera to add style sheets to the CGI
814 interface, allowing easy customization. Added new icons and
815 BackupPC logo. Numerous navigation improvements.
817 * Added directory history display to BackupPC_Admin, allowing the
818 user to quickly see which files changed between backups on a
821 * Added exponential expiry option for full dumps. This allows you
824 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
825 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
826 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
827 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
828 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
830 and so on. This allows you, for example, to keep 4 weekly fulls,
831 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
832 16 weeks, for roughly 1 year of history. This works by deleting
833 every other full as each expiry boundary is crossed. Suggested
836 * Added Italian language translation it.pm from Lorenzo Cappelletti.
838 * Major updates to language files for new features and tags changes.
839 Updated makeDist to do pedantic consistency checking of language
842 * Addition of administration options from Paul Lukins. Initial
843 page allows server to be started/stopped/reloaded. This still
844 needs some i18n work. Currently the server start/stop is
847 * Split BackupPC_Admin into a set of modules, one for each major action.
848 Each action is now a seperate module in lib/BackupPC/CGI.
850 * Allow the blackout period begin/end to span midnight. Adapted
851 from patch submitted by David Smith.
853 * Allow multiple blackout periods, with new config variable
854 $Conf{BlackoutPeriods} that replaces the old variables
855 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
856 $Conf{BlackoutWeekDays}. Based on patch submitted by
859 * Disabled alarms after forks to avoid timeouts in children that
860 do not reset their alarm. Prompted by ideas from James Leu.
862 * Added options for block size, buffer size and share wild-card to
863 BackupPC_tarCreate. Also added negative backup number options
864 that are relative to the last (so -1 is the last), suggested by
865 William McKee and Carl Soderstrom.
867 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
868 the user is more likely to see the error with BackupPC_tarCreate.
869 Reported by Paul Fox.
871 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
872 case it doesn't already exist.
874 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
875 SI Reasoning and Niranjan Ghate.
877 * Changed restore code so that option #1 (direct restore) can be
878 disabled if the restore command is undefined. Disabling direct
879 restore is necessary if the share is read-only. Suggested by
882 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
883 a decimal point or comma for international versions of Samba.
884 Patch submitted by Frank Gard.
886 * Browsing and directory history now sort the files in a
887 case-insensitive manner.
889 * Changed exec() syntax to allow executing commands whose path
892 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
893 is zero or undefined. The protects the existing backups in the
894 case of a bad config.pl file. Suggested by Christian Warden.
896 * Swapped the Server and Hosts sections on the Nav bar. Moved the
897 host search text box to the top of the hosts section. This was
898 done to move the variable-length part of the Nav bar (when all
899 hosts are displayed) to the bottom.
901 * Fixed a bug in tar restore related to how the common prefix path is
902 removed. Now ensure that the common path is at a directory boundary.
903 Reported by Patrick Neuner.
905 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
906 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
908 * Added Suse notes to init.d/README from Bruno Vernay.
910 * Added Apache 2 documentation fix from Michael Tuzi.
912 #------------------------------------------------------------------------
913 # Version 2.0.2, 6 Oct 2003
914 #------------------------------------------------------------------------
916 * Fixed stupid last-minute change in octal size conversion in
919 #-----------------------------------------------------------------------
920 # Version 2.0.1, 5 Oct 2003
921 #------------------------------------------------------------------------
923 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
924 files in BackupPC_tarCreate.
926 * Removed smbclient size repair in BackupPC_tarExtract for files
927 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
928 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
929 extacted using smbclient 2.2.x. If you have problems backing up
930 files whose size is between 2GB and 4GB using smbclient 2.2.x
931 you should upgrade smbclient to 3.0, since it now generates
934 * Replace PingClientPath with PingPath in configure.pl.
936 * Removed -T (taint mode) on binaries installed in configure.pl.
938 * Added support for smbclient from samba version 3.0.0.
940 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
943 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
944 if it is not defined. This allows the CGI interface to work
945 when AdminUsers = '*'. Reported by Quentin Arce.
947 * For SMB, code that detected files with a read-locked region (eg:
948 outlook .pst files), removed them and then tried to link with an
949 earlier version was broken. This code missed a step of mangling
950 the file names. This is now fixed. Reported by Pierre Bourgin.
952 * A backup of a share that has zero files is now considered
953 fatal. This is used to catch miscellaneous Xfer errors that
954 result in no files being backed up. A new config parameter
955 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
956 zero to turn off this check. Suggested by Guillaume Filion.
957 Additional change: this check only applies to a full dump.
959 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
960 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
961 smbclient.) Suggested by Guillaume Filion.
963 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
964 the dump is considered failed.
966 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
967 which just included the '/' directory and nothing below. Now it
968 does just --include '/', which should include everything.
971 * Add hostError to DumpPostUserCmd variable substitutions for both dump
974 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
975 makes BackupPC_dump -v work better.
977 * Don't allow browsing with ".." in directory in case a user tries
978 to trick BackupPC_Admin into displaying directories outside where
981 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
982 fixes large file (>2GB) bugs. Large file bugs reported by Steve
985 #------------------------------------------------------------------------
986 # Version 2.0.0, 14 Jun 2003
987 #------------------------------------------------------------------------
989 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
990 Added "no utf8" to all programs, and added binmode() to relevant
993 #------------------------------------------------------------------------
994 # Version 2.0.0beta3, 1 Jun 2003
995 #------------------------------------------------------------------------
997 * Several improvements to restore: cancel now reports the correct
998 message and cleans up correctly.
1000 * Rsync with whitespace and wildcard excludes fixed by replacing
1001 argList with argList+ in config.pl plus a fix to Lib.pm for
1002 shell escaping array arguments.
1004 * Fixed rsync restore for character and block special devices
1005 (major and minor device numbers weren't correctly restored).
1007 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
1009 * (Re)-fixed "Bad command" in log file when restore via tar or zip
1010 file download is done.
1012 * Added untaint to exec in Lib.pm to avoid tainted errors.
1014 * Applied additional tweak to hilight patch from Tim Demarest.
1016 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
1019 * Don't display RsyncdPasswd when displaying config.pl files.
1021 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
1022 which increases typical buffering from 4K to 16K-64K. This improves the
1025 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
1026 then a warning is printed.
1028 #------------------------------------------------------------------------
1029 # Version 2.0.0beta2, 11 May 2003
1030 #------------------------------------------------------------------------
1032 * Added German translation, provided by Manfred Herrmann.
1034 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
1036 * Fixed zip and tar file download from CGI under mod_perl. Reported
1037 by Pierre Bourgin and Paul Lukins.
1039 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
1040 Reported by several users.
1042 * Added -v option to BackupPC_dump for verbose output (useful when
1043 you run the command manually). Added messages for all exits.
1045 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
1046 now returns the first IP address that matches the subnet mask.
1047 Suggested by Tim Demarest.
1049 * Fixed BackupPC::View so the top-level directory is handled correctly.
1050 This allows the top-level share/directory to be restored via the
1051 CGI interface. Reported by several users.
1053 * Fixed RsyncFileIO failures on certain large files by replacing seek()
1054 with sysseek(). Reported by Manfred Herrmann.
1056 * Added configurable highlighting of PC status in the CGI summary
1057 screen; submitted by Tim Demarest.
1059 * Fixed command queue CGI display; submitted by Tim Demarest.
1061 * BackupPC_trashClean now logs an error if it can't remove all the
1062 trash and then goes back to sleep, rather than continually trying.
1064 * Moved correct user (uid) check into BackupPC::Lib so that all
1065 applications do a user check if $Cong{BackupPCUserVerify} is
1066 set. The avoids the risk of manually running BackupPC_dump as
1069 * Loss of blackout now applies to "host not found" as well as no ping.
1070 Reported by Dale Renton.
1072 * "Host not found" is now treated in a similar manner to "no ping".
1074 * Added suse-linux init.d script from Leon Letto.
1076 * Added Gentoo linux init.d script from Tim Demarest.
1078 * Applied additional i18n strings from GFK and the translation team.
1080 * Fixed option parsing so that getopts errors are reported and we exit.
1082 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
1084 #------------------------------------------------------------------------
1085 # Version 2.0.0beta1, 30 Mar 2003
1086 #------------------------------------------------------------------------
1088 * Added Spanish translation es.pm from Javier Gonzalez.
1090 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
1091 when directories were selected in a certain order.
1093 * Fixed BackupPC::PoolWrite so that it can recover when the initial
1094 file size is wrong. This is needed since rsync could write a file
1095 whose size is different from the initial size returned in the
1096 file list when that file is updated while rsync is running.
1098 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
1099 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
1100 helps, but it should be benign. See:
1101 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
1103 #------------------------------------------------------------------------
1104 # Version 2.0.0beta0, 23 Feb 2003
1105 #------------------------------------------------------------------------
1107 * Support for rsync and rsyncd backup and restore. Changes to
1108 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
1109 and BackupPC::Xfer::RsyncFileIO.
1111 * Added internationalization (i18n) code from Xavier Nicollet,
1112 with additions from Guillaume Filion. Voila! BackupPC_Admin
1113 now supports English and French, and adding more languages is
1114 now easy. New config paramater $Conf{Language} sets the language.
1116 * Added optional user-defined pre/post dump/restore commands, allowing
1117 things like database shutdown/startup for dumps.
1119 * Changed the way hosts are found.
1121 * Added $Conf{ClientNameAlias}, which allows the name of the physical
1122 client machine to be set. This allows several different backup
1123 "hosts" to all refer to the same physical machine, which is
1124 convenient if several different types of data need to be backed
1125 up, or if different parameters are needed for different parts of
1128 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
1129 $Conf{NmbLookupCmd} allowing all these commands to be fully
1130 configured. Also, all commands can also now be fragments of
1133 * Moved all smbclient commands into the config.pl file so the specific
1134 arguments can be customized. New config parameters are
1135 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
1136 $Conf{SmbClientRestoreCmd}.
1138 * Added new BackupPC::View module that creates views of backups
1139 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
1140 and BackupPC_tarCreate to use BackupPC::View. This removes lots
1141 of merging and mangling code from the higher-level code.
1143 * Added code from Toby Johnson that allows additional users to be
1144 specified in the hosts file; these users can also view/start/stop
1145 and restore backups for that host. Also added a new config
1146 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
1147 be listed in the left nav bar for admins.
1149 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
1150 the maximum number of hardlinks per file in the pool. If a file
1151 ever gets to this number of links a new pool file is created to
1152 handle additional links.
1154 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
1155 modules to be loaded.
1157 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
1158 allow language-specific default messages to be overridden.
1160 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
1161 files to be represented in the attrib file correctly.
1163 * Added support for environment variable BPC_SMB_PASSWD, which is the
1164 client's smb password. This overrides the old environment variable
1167 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
1169 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
1170 handle files with trailing spaces.
1172 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
1173 to ignore multiple signals of the same type.
1175 * Added reporting of the largest number of hardlinks in the pool to the
1178 * Adding reporting of syntax errors in the per-PC config.pl file.
1180 * Updated BackupPC_sendEmail to handle language-specific email messages.
1182 * Allow client (host) names to contain spaces. Spaces in host names
1183 need to be escaped via "\" in the hosts file. The user of spaces in
1184 host names is discouraged, but they should work. One feature that
1185 doesn't work with host names that contain spaces is the highlighting
1186 of that name in the log file display in the CGI interface. There are
1187 no plans to fix this.
1189 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
1191 * Fixed all open() calls to use 3 argument form to fix handling of file
1192 names with trailing whitespace. Also fixed CGI interface so these
1193 file names are displayed correctly.
1195 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
1196 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
1197 Reported by Pascal Schelcher. Fixed similar problem reported by
1200 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
1201 suggested by Tim Demarest.
1203 #------------------------------------------------------------------------
1204 # Version 1.5.0, 2 Aug 2002
1205 #------------------------------------------------------------------------
1207 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
1208 option instead of --newer-mtime. Also removed --atime-preserve from
1209 $Conf{TarClientCmd}. This makes the default settings work better
1212 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
1213 so it can correctly warn the user to stop it before upgrading. Reported
1216 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
1217 Reported by Guillaume Filion.
1219 * Added LDAP setup to documentation from David Holland.
1221 * Tar.pm now adds a "." to file paths that start with "/", so that all
1222 tar paths are relative. From Ludovic Drolez.
1224 #------------------------------------------------------------------------
1225 # Version 1.5.0beta0, 30 Jun 2002
1226 #------------------------------------------------------------------------
1228 * A full set of restore options is now supported, including direct
1229 restore via smbclient or tar or downloading a zip or tar file.
1231 * Major additions to CGI script to support better directory navigation,
1232 restore features and mod_perl. Also, file downloads from the CGI
1233 interface now correctly preserve the file name and provide the
1234 correct Content-Type for the most common types of files. Improved
1235 directory navigation was contributed by Ryan Kucera.
1237 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
1238 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
1239 create a zip archive of any portion of a backup.
1241 * Substantial additions to BackupPC_tarCreate to support restore,
1242 including modifying path names, handling hardlinks, fixing
1243 support of old backups without attributes (pre-v1.4.0). Plus
1244 BackupPC_tarCreate is now an offical part of the release.
1245 (Lack of support for hardlinks was reported by John Stanley.)
1247 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
1250 * A unix domain socket is now used for communication between the CGI
1251 interface and BackupPC. The original TCP socket is optional. Sockets
1252 are correctly re-initialized if config.pl is updated with new socket
1255 * For improved security messages over the unix or TCP socket are protected
1256 via an MD5 digest based on a shared secret, a sequence number, a time
1257 stamp and a unique per-connection number.
1259 * Additions to configure.pl to support install of directory navigation
1262 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
1263 were set to a single string or list (in v1.4.0 only the case of
1264 hash worked correctly). Reported by Phillip Bertolus.
1266 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
1267 client always subject to blackout, matching the comments in config.pl.
1268 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
1269 reported by Pascal Schelcher.
1271 * Fixed byte and file totals for tar backups, reported by several users.
1273 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
1274 suggested by Erminio Baranzini.
1276 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
1277 well as shell escaping of tar arguments.
1279 * Fixed entity encoding of 8-bit characters in the CGI interface.
1281 * Added optional CGI headers in $Conf{CgiHeaders} that by default
1282 is set to a no-cache pragma. Suggested by Benno Zuure.
1284 #------------------------------------------------------------------------
1285 # Version 1.4.0, 16 Mar 2002
1286 #------------------------------------------------------------------------
1288 * BackupPC now supports tar (in addition to smb) for extracting host
1289 data. This is the most convenient option for linux/unix hosts.
1290 Tar can be configured to run over ssh, rsh or to backup a local
1291 nfs mount from the host.
1293 * Support for special files, including symbolic links, fifo, character
1294 and block device files has been added, so that all native linux/unix
1295 file types can be correctly backed up when using tar transport.
1296 Special files are all stored as regular files and the type attributes
1297 are used to remember the original file type.
1299 * All unix file attributes are now saved (and pooled when possible).
1300 This includes user and group ownership, permissions, and modification
1301 time. Smbclient also does a reasonable job of emulating unix
1302 permissions (such as mtime), and these attributes get saved too.
1304 * The new default is to not fill incremental dumps. configure.pl
1305 automatically sets $Conf{IncrFill} to 0. The default was 1
1306 (incrementals were filled with hardlinks). Since the CGI
1307 script does filling at browsing time, there is no need to
1308 fill incremental dumps.
1310 * Backup file names are now stored in "mangled" form. Each node of a
1311 path is preceded by "f", and special characters (\n, \r, % and /) are
1312 URI-encoded as "%xx", where xx is the ascii character's hex value. So
1313 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
1314 was done mainly so meta-data could be stored alongside the backup
1315 files without name collisions. In particular, the attributes for the
1316 files in a directory are stored in a file called "attrib", and
1317 mangling avoids file name collisions (I discarded the idea of having
1318 a duplicate directory tree for every backup just to store the
1319 attributes). Other meta-data (eg: rsync checksums) could be stored in
1320 file names preceded by, eg, "c". There are two other benefits to
1321 mangling: the share name might contain "/" (eg: "/home/craig" for tar
1322 transport), and I wanted that represented as a single level in the
1323 storage tree. Secondly, as files are written to NewFileList for later
1324 processing by BackupPC_link, embedded newlines in the file's path
1325 will cause problems which are avoided by mangling.
1327 The CGI script undoes the mangling, so it is invisibe to the user.
1328 Of course, old (unmangled) backups are still supported by the CGI
1331 * Various changes to the CGI interface, BackupPC_Admin:
1333 + Added button that allows users to manually start a full dump in
1334 addition to the existing incremental dump.
1336 + Added display of file attributes when browsing backups.
1338 + Added an optional holdoff time specified by the user when canceling
1339 a backup. BackupPC will not attempt any new backups for at least the
1340 specified time. This holdoff time can be changed whether or not a
1343 + Added supports for file mangling, and correct merging of unfilled
1344 backups from mangled or unmangled (and compressed or uncompressed)
1345 fulls when browsing or restoring.
1347 + Only displays a "Start Incr Backup" button if there are already some
1350 + For DHCP hosts, when a user tries to manually start a backup, add
1351 a check for the netbios name of both the host the request came
1352 from (REMOTE_ADDR) and the last known DHCP address for that host
1353 to see if either address matches the host. If not, an error
1354 message is display. The previous behavior was that only requests
1355 from the client itself succeeded, and requests from other machines
1358 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
1359 is 1.4.0. The first digit is for major new releases, the middle digit
1360 is for significant feature releases and improvements, and the last
1361 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
1362 and 1.03 as 1.0.0, ..., 1.3.0.
1364 * BackupPC and the CGI script BackupPC_Admin now check that the effective
1365 user id is correct to avoid accidentally launching BackupPC as the
1366 wrong user or detecting CGI configuration problems. This behavior
1367 can be turned off using the $Conf{BackupPCUserVerify} option.
1369 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
1370 support generic names for both smb and tar transport methods. The
1371 CGI script checks for old names for backward compatibility.
1373 * Major changed to Backup_dump to support new tar transport. All transport
1374 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
1377 * Added workaround for a bug in Samba's smbclient for files between 2GB
1378 and 4GB. The file size in the tar header is incorrect. This allows
1379 files up to 4GB to work with smbclient, rather than 2GB. To support
1380 files larger than 2GB you must make sure perl is compiled with the
1381 uselargefiles option (use "perl -V | egrep largefiles" to check) and
1382 the pool directory must be on a file system that supports large files.
1384 * Moved the pool writing code into a module BackupPC::PoolWrite. This
1385 allows the clever file pool checking (digest, uncompressing, comparing
1386 etc with minimum disk IO) to be used easily in multiple places (eg: it
1387 is now used for writing attribute files so they can be pooled).
1389 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
1391 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
1392 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
1393 on one user's machine was world writable and perl -T correctly
1394 complained about it.
1396 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
1397 Thanks to Kyle Amon for sending the fix. Decided to move the
1398 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
1399 now configure.pl tries to come up with a sensible default based on
1402 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
1403 share name (eg: C$). Thanks to Jules Agee for this fix. Also
1404 changed the default config.pl so that single quotes are used
1405 everywhere so that people don't get tripped up putting '$' inside
1406 double-quoted strings.
1408 #------------------------------------------------------------------------
1409 # Version 1.03, 9 Dec 2001
1410 #------------------------------------------------------------------------
1412 * BackupPC now has full support for compression. There are now two
1413 pool areas, the original pool for uncompressed files, and cpool for
1414 compressed files. The compression is done by Compress::Zlib.
1415 Compression reduces the pool disk usage by around 40%, although your
1416 mileage may vary. Compression is optional and can also be specified on
1417 a per-PC basis (although this will cost more pool storage since many
1418 backup files will have to be stored in both compressed and
1421 * A new script, BackupPC_compressPool, can be run to compress the entire
1422 pool. This is used once to migrate all the pool data from uncompressed
1423 to compressed on existing installations. Read the documentation
1424 (Installing BackupPC/Compressing an existing pool) before running
1425 BackupPC_compressPool!
1427 Alternatively, compression can simply be turned on and all new backups
1428 will be compressed. Both old (uncompressed) and new (compressed)
1429 backups can be browsed and viewed. Eventually, the old backups will
1430 expire and all the pool data will be compressed. However, until the
1431 old backups expire, this approach could require 60% or more additional
1432 pool storage space to store both uncompressed and compressed versions
1433 of the backup files.
1435 * Significant improvements to the cgi interface, BackupPC_Admin:
1437 - much better layout navigation
1438 - handles compressed backup files and compressed log files
1439 - handles unfilled incremental dumps
1440 - better backup directory browsing navigation
1441 - reports compression statistics
1442 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
1443 - Additional customization with $Conf{CgiHeaderFontType},
1444 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
1445 $Conf{CgiHeaderBgColor}.
1447 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
1448 file and queues the PCs itself. Like config.pl, BackupPC will
1449 re-read the hosts file on each wakeup if its modification time
1450 changes, or upon a SIGHUP. This also makes for better behavior
1451 when adding a host: if you add hosts, simply send a SIGHUP to
1452 BackupPC or wait for the next wakeup.
1454 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
1456 * BackupPC_dump keeps track of compressed file sizes so that compression
1457 statistics can be reported by the cgi interface.
1459 * Aging of old log files now handles compressed log files (.z extension).
1461 * Added configuration option $Conf{IncrFill} to specify whether
1462 incremental dumps should be filled in. Old behavior was that
1463 filling was on. Now it's optional. See config.pl for more
1466 * BackupPC_nightly now cleans and generates statistics for both
1467 the uncompressed pool and compressed pool (cpool).
1469 * Added new utility script BackupPC_zcat that can be used to
1470 uncompresses BackupPC files.
1472 * configure.pl offers various options related to compression,
1473 depending upon whether this is a new install or upgrade,
1474 and whether or not Compress::Zlib is installed.
1476 * configure.pl now makes a backup copy of config.pl before
1477 config.pl is updated.
1479 * added three new fields to the backups file to handle optional
1480 filling and compression stats.
1482 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
1483 on each dhcp host once each night to verify that very old backups are
1484 expired. This ensures that very old backups are expired even if
1485 the dhcp host has not been on the network for a long time.
1487 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
1488 even if compression was off. Thanks to Steve Holmes for reporting
1491 * fixed bug that caused a BackupPC queue to get blocked when a backup
1492 cancel attempt was made during the BackupPC_link phase.
1494 #------------------------------------------------------------------------
1495 # Version 1.02, 28 Oct 2001.
1496 #------------------------------------------------------------------------
1498 * Added new script BackupPC_tarExtract to extract the smbclient tar
1499 archive. This reduces disk writes by perhaps 90-95% and disk reads by
1500 50%. Previously, tar was used to extract and write everything to disk.
1501 Then BackupPC_dump would read enough of each file to compute the MD5
1502 digest, and then compare the full file with candidate pool files. So
1503 for each 1MB file that matches a single file in the pool, there would
1504 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
1506 BackupPC_tarExtract instead extracts the archive using a 1MB memory
1507 buffer. This allows the MD5 digest to be computed without touching the
1508 disk. Next, any potential pool file compares are done by comparing the
1509 pool file against the incoming tar data in memory, which only requires
1510 the pool file to be read. So for each 1MB file that matches a single
1511 file in the pool, there are now no disk writes, and only 1MB of reads.
1512 BackupPC_tarExtract handles arbitrary size files and repeated
1513 potential pool matches. If the incoming file doesn't match the pool
1514 then it is written to disk (once the pool is mature this happens maybe
1517 * Substantial changes to BackupPC_dump:
1519 + BackupPC_tarExtract is now used in place of tar.
1521 + BackupPC_dump now reads the output from both smbclient and
1522 BackupPC_tarExtract and merges them into SmbLOG.
1524 + Named pipes are no longer used to connect smbclient to tar
1525 (now BackupPC_tarExtract). Regular pipes are used instead.
1526 This avoids the need to system mknod or mkfifo.
1528 + Locked files on the client that can't be read by smbclient
1529 previously were filled with 0x0 bytes by smbclient, meaning
1530 tar extracted a useless file filled with 0x0 bytes. Now,
1531 BackupPC_dump watches the output of smbclient and removes
1532 any files that smbclient couldn't read. This avoids storing
1533 useless files. It tries to replace such files with a hard link
1534 to a previous dump. These actions appear in the log file.
1536 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
1537 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
1538 reading and writing compressed and regular files and provides all the
1539 hooks for compression support in BackupPC (should be supported in next
1540 version). BackupPC::FileIO also does efficient writing of files that
1541 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
1542 helpful when smbclient reads a locked file, and it fills the tar
1543 output with a file of the correct size but all 0x0. Such files will be
1544 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
1545 writes such files efficiently (as sparse files), meaning just a few
1546 blocks of disk space will be needed even if the file is large.
1548 * alive/dead counting for blackout now works correctly for DHCP hosts.
1550 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
1551 killed and restarted with backups running.
1553 * added extra non blocking select() in BackupPC to make sure the socket
1556 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1558 * Updated BackupPC_sendEmail to correctly parse the locked file
1559 error from 2.2.1a smbclient, so that missing Outlook file emails
1560 can be correctly sent.
1562 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1563 hostname read from the hosts file.
1565 * BackupPC_Admin provides general summary when the host name is empty.
1567 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1569 * configure.pl complains if BackupPC is already running, reminding you
1570 to stop it before upgrading.
1572 * updated documentation, and fixed auto-insertion of config.pl into
1573 BackupPC.pod (previously the last config parameter was left out of
1576 #------------------------------------------------------------------------
1577 # Version 1.01, 30 Sep 2001
1578 #------------------------------------------------------------------------
1580 * Documentation cleanup in README, doc/BackupPC.pod, conf/config.pl.
1582 * BackupPC_sendMail now reads the optional per-PC config file, allowing
1583 email configuration parameters to be set on a per-PC basis.
1585 * Removed the unused 4096-length MD5 digest code in lib/BackupPC/Lib.pm.
