21 # Version __VERSION__, __RELEASEDATE__
22 #------------------------------------------------------------------------
24 #------------------------------------------------------------------------
25 # Version 3.1.0, 25 Nov 2007
26 #------------------------------------------------------------------------
28 * Fixed config editor bug for case where override is unchecked on
29 an array where the current array is shorter than the main config's
32 * Fixed missing close quote in BackupPC_archiveHost reported by Franky
35 * Replaced "$BinDir/.." with $bpc->InstallDir() for path to BackupPC
36 docs, mentioned by Kenneth Porter.
38 * Moved default of $Conf{IncrLevels} from lib/BackupPC/Storage/Text.pm
39 to lib/BackupPC/Lib.pm (after the merge of the config files). This
40 fixes a bug that caused $Conf{IncrLevels} to get over-ridden if it
41 was only defined in the main config file. Reported by John Rouillard.
43 * Fixed the completion status message in BackupPC_dump so that missing
44 error counts appear as 0, rather than empty. Reported by Bill.
46 * Changed lib/BackupPC/Xfer/RsyncFileIO.pm to only increment the error
47 count when the md4 checksum fails on the second phase, not the first.
48 Reported by Adrian Bridgett.
50 * Updated a comment in config.pl about BackupPC_nightly, reported by
53 * Modified lib/BackupPC/CGI/Restore.pm to ensure that the list of hosts
54 presented for direct restore do have direct restore enabled. Reported
57 * Modified lib/BackupPC/CGI/RestoreFile.pm to replace \n with \r\n in
58 the restore http response headers. Patch submitted by Thomas Eckhardt.
60 #------------------------------------------------------------------------
61 # Version 3.1.0beta1, 21 Oct 2007
62 #------------------------------------------------------------------------
64 * When there is an existing partial, a new partials is only saved
65 if it has more files than the existing partial. Requested by
68 * Fixed handling of $Conf{BackupFilesExclude} for tar XferMethod.
69 Patch supplied by Frans Pop.
71 * Fixed numeric column sorting in host summary table, reported by
74 * Fixed host CGI editor so it creates the new host's config.pl file
75 using the lower-case host name, since host names are mapped to
76 lower case when they are read from the hosts file. Reported by
79 * Applied documentation patches from Frans Pop. Also updated
80 Pod::Html to improve documentation formatting.
82 * Added Polish translation from Semper.
84 * Fixed BackupPC_nightly reporting of repeated pool file hashes.
86 * Add run-time check that IO::Dirent is functioning correctly,
87 reported by Doug Lytle.
89 * Added comment to Cmd settings in conf/config.pl that they are
90 not executed by a shell, as suggested by Erik van Linstee.
92 * Added undefIfEmpty => 1 to lib/BackupPC/Config/Meta.pm for
93 RsyncRestoreArgs, TarClientRestoreCmd and SmbClientRestoreCmd
94 so that restores can be disabled by clear these fields in the
95 CGI editor. Patch supplied by Stephen Joyce
97 * Replaced the FAQ link with Wiki in the navigation bar and added
98 mention of the Wiki to the documentation. Since these navigation
99 bar links are specified in the config file, upgrades will keep
100 the old FAQ link. The FAQ opening page will have a prominent
103 #------------------------------------------------------------------------
104 # Version 3.1.0beta0, 3 Sep 2007
105 #------------------------------------------------------------------------
107 * Added new script BackupPC_archiveStart that allows command-line
108 starting of archives. Based on script written by Sergey Kovzik,
109 which in turn was based on an earlier version by Holger Parplies.
111 * Added Simplified Chinese CGI translation from Youlin Feng,
112 plus fixed a couple of cases where utf8 share names were
113 not displayed correctly.
115 * Added sorting by column feature to host summary table in CGI
116 interface. Implemented by Jeremy Tietsort.
118 * Added optional support for IO::Dirent which allows inode information
119 to be extracted from the dirent directory structure. This allows
120 BackupPC to order some directory operations by inode, which on
121 some file systems (eg: ext3) can results in a 20-30% performance
122 gain. On other file systems there is no real improvement. This
123 optimization is turned on automatically if IO::Dirent is installed.
125 * Added some performance improvements to BackupPC::Xfer::RsyncFileIO
126 for the case of small files with cached checksums.
128 * Added check to BackupPC at startup that $TopDir can support
129 hardlinks. Also added check to BackupPC_dump that a hardlink
130 below $TopDir/pc/HOST can be made to below $TopDir/cpool.
131 Also added the need for a hard-link capable file system to
132 the documentation. Suggested by Nils Breunese.
134 * Added FreeBSD init.d file provided by Gabriel Rossetti.
136 * Added -l and -L options to BackupPC_tarCreate so that
137 provide a file list (without creating the archive).
140 * Made the default charset for BackupPC_zipCreate cp1252, which
141 appears to work correctly with WinZip. Unfortunately there is
142 no clear standard for charset encoding in zip files.
144 * Added support so that pre-3.0 backups with non-utf8 charsets
145 can be viewed and restored correctly. A new config variable
146 $Conf{ClientCharsetLegacy} specifies the charset used to
147 encode file names in legacy backups. This is only relevant
148 if you are trying to view or restore a backup made with
149 BackupPC 2.x and some of the file names have non-ascii
152 * Added setting of the environment variable BPC_REQUSER to
153 the requesting user name in BackupPC prior to fork(), so
154 each child process inherits the value. Submitted by
157 * Fixed bug in rsync incrementals that happens on particular
158 file names when a file being backed up fails in both rsync
159 phases. Reported by Dan Smisko.
161 * Fixed single-restore file name charsets for IE, reported by
164 * Fixed makeDist so that the --config-dir option to configure.pl
165 works correctly. Reported by Randy Barlow, Tony Shadwick and others.
167 * Removed ConfDir from config editor (since it is hardcoded in
168 lib/BackupPC/Lib.pm). Also made TopDir and LogDir only visible
169 if useFHS (for non-FHS they are hardcoded in lib/BackupPC/Lib.pm).
171 * Applied patch from Holger Parplies that fixes cleanup of early abort
174 * Applied small patch from Sergey to lib/BackupPC/Xfer/Tar.pm that makes
175 it ignore "socket ignored" error on incrementals.
177 * Applied small patch from Sergey to bin/BackupPC_archiveHost.
179 * Changed BackupPC_sendEmail so that summary admin email doesn't
180 include errors from hosts that have $Conf{BackupsDisable} set.
181 Reported by James Kyle. Also, per-user email is now disabled
182 when $Conf{BackupsDisable} is set.
184 * Added RsyncdUserName to the config editor. Reported by Vicent Roca Daniel.
186 * $Conf{IncrLevels} is now defaulted if it is not defined.
188 * configure.pl clears $Conf{ParPath} if it doesn't point to a valid
191 * Added documentation for BackupPC_tarPCCopy, including use of -P option
192 to tar suggested by Daniel Berteaud.
194 * Config editor now removes white space at start of exec path.
195 Reported by Christoph Iwasjuta.
197 * CgiDateFormatMMDD == 2 gives a YYYY-MM-DD format for CGI dates,
200 #------------------------------------------------------------------------
201 # Version 3.0.0, 28 Jan 2007
202 #------------------------------------------------------------------------
204 * BackupPC_sendEmail now correctly sends admin email if backups
205 were skipped because the disk was too full, reported by Dan
208 * BackupPC_Admin now uses $Conf{UmaskMode}, so config.pl files
209 written by the editor have more restrictive permissions.
210 Reported by Tim Massey.
212 * Host summary now shows active backups on disabled hosts,
215 * Fixed host LOG link and LOG list order, reported by Tim Massey.
217 * Moved Encode.pm version check to start of configure.pl so it
218 produces a useful error message if Encode.pm is too old.
220 * Fixed hrefs to configuration documentation to handle changes
221 in the way perl generates the anchors. Reported by Philip
224 * Host name links in LOG files now allow "." in the host name.
225 Reported by Jean-Michel Beuken.
227 * Fixes to lib/BackupPC/Xfer/Tar.pm for tar 1.16: allow 1
228 (ie: 256) as a successful exit status and match "Total
229 bytes read" message for restores. First reported by
230 Torsten Sadowski and debugged by Ralf Gross and Holger
233 #------------------------------------------------------------------------
234 # Version 3.0.0beta3, 3 Dec 2006
235 #------------------------------------------------------------------------
237 * Removed default paths from conf/config.pl so configure.pl will
238 determine the correct ones at install time. Avoids problem of
239 the config editor complaining about bad executable paths the
240 first time you use it.
242 * Changed first byte of compressed files with rsync checksums appended
243 to 0xd7 to allow correct protocol_version >= 27 md4 checksums to be
244 written. Old cached checksum files have a first byte 0xd6 and are
245 now considered to be uncached. They will be automatically updated
246 as needed. This avoids the cached checksum warnings in beta2.
248 * BackupPC_tarPCCopy now handles all file types correctly. Reported
251 * Fixed BackupPC_nightly to finish pending deletes before renaming
254 * Fixes for rsync restore where hardlink is to file outside of the
255 top-level restore directory. Reported by George Avrunin, who helped
258 * Fixes for checksum mismatch on restore for certain file sizes.
259 Reported by George Avrunin and others.
261 * Fix for config.pl writing code to handle multi-line expressions.
262 Reported by David Relson and others.
264 * Fix for CGI editor when deleting hash entries whose keys are
265 non alphanumeric. Report by David Relson and Aaron Ciarlotta.
267 * Two fixes to configure.pl from Andreas Vögele.
269 #------------------------------------------------------------------------
270 # Version 3.0.0beta2, 18 Nov 2006
271 #------------------------------------------------------------------------
273 * Fix for final md4 digest check on rsync transfers >= 512MB when protocol
274 version >= 27 and checksums are not cached. Reported by Garith Dugmore
277 * Config Editor "Save" button is now always visible, but greyed out
278 until there are changes to save.
280 * Config editor allows other tabs to be selected when there is an
281 error, which allows you to fix an error (eg: missing binary) in
282 an exiting config file. Errors are now displayed at the top of
283 the page in addition to next to the erroneous setting.
285 * configure.pl checks version of Encode.pm. Reported by Chris Stone.
287 * Several fixes to bin/BackupPC_fixupBackupSummary from Stian Jordet.
289 * Fixed config.pl editor writing to solve bug with multi-line text
290 strings ending in newline. Reported and root caused by Les Stott
293 * Fixed error recovery case in BackupPC::PoolWrite, reported by
296 * Fixed table width in backup browsing to avoid Firefox layout anomoly,
297 provided by Jono Woodhouse.
299 * CSS file updates from Jono Woodhouse. Prior (v2) version is included
300 as BackupPC_stnd_orig.css in case people prefer the old skin.
302 * More compact host summary, including disabled host indication,
305 * New directory/file/hardlink and symlink image icons from Sean Cameron
306 and Jono Woodhouse, making directory browse more compact.
308 * BackupPC.pid is now world readable, suggested by Casper Thomsen.
310 * Reordered the Server navigation bar links, suggested by David Relson.
312 * Fixed typos in init.d/src/gentoo-backuppc, configure.pl and config.pl
313 reported by David Relson.
315 #------------------------------------------------------------------------
316 # Version 3.0.0beta1, 30 Jul 2006
317 #------------------------------------------------------------------------
319 * Fixed several Xfer charset conversions.
321 * Added some CGI utf8 conversions from Rodrigo Real and Vincent
324 * Rsync transfers now correctly handle file names with \n or \r.
326 * Host name is forced to lower case, to match 2.x.
328 * Fixed LOG file naming in BackupPC_restore and BackupPC_archive.
330 * GFK applied fr.pm corrections from Nicolas Stransky.
332 * Updated init.d/src scripts for FHS (ie: replaced __TOPDIR__/log
333 with __LOGDIR__ and __TOPDIR__/conf with __CONFDIR__). Patch
334 provided by Rodrigo Real.
336 * Added --log-dir and --conf-dir options to configure.pl.
337 Reported by Vincent Fleuranceau.
339 * Updated File::RsyncP version check in configure.pl, reported
340 by Vincent Fleuranceau. Changed File::RsyncP version to 0.64.
342 #------------------------------------------------------------------------
343 # Version 3.0.0beta0, 11 Jul 2006
344 #------------------------------------------------------------------------
346 * Added configuration and host CGI editor.
348 * Added rsync hardlink support. Requires latest version of
351 * Decoupled BackupPC_dump from BackupPC_nightly by making
352 asynchronous file linking/delete robust to race conditions.
353 Now only BackupPC_nightly and BackupPC_link are mutually
354 exclusive so only one runs at a time, and BackupPC_dump and
355 BackupPC_restore can run anytime.
357 * Added support for multi-level incrementals. In the style of dump(1),
358 the level of each incremental can be specified. Each incremental
359 backups up everything since the most recent backup of a lower level
360 (fulls are always level 0). Previous behavior was all incrementals
361 were level 1, meaning they backed up everything since the last full
362 (level 0). Default configuration is all incrementals are level 1.
364 * Server file names are now in utf8 and optional conversion
365 to/from client name charsets can be configured. All CGI pages
366 now use the utf8 charset.
368 * Backup metadata is now additionally saved to pc/HOST/nnn/backupInfo,
369 in addition to pc/HOST/backups. In case pc/HOST/backups gets trashed,
370 then a new script BackupPC_fixupBackupSummary can read the per-backup
371 metadata from pc/HOST/nnn/backupInfo and reconstruct the backups file.
372 Roberto Moreno also pointed out an early error in the CVS version.
374 * Added Storage module and Storage::Text which localizes all the
375 text data file reading/writing (eg: backups, restores, archives
376 and config.pl files). Added read verify after all write
377 operations for robustness. Additional backends (eg: SQL)
378 can be added in the future as new subclasses of the Storage
381 * Added Config module, and Config::Meta that contains meta data
382 about configuration parameters.
384 * Added RSS support from Rich Duzenbury.
386 * Translations of new 3.0 language strings from Guillaume Filion,
387 Reginaldo Ferreira, Ralph Passgang, Lieven Bridts, Guus Houtzager,
390 * Added optional checking of exit status of Dump/Restore/Archive Pre/Post
391 UserCmd, requested by Kiko Jover, Matthias Bertschy and others.
393 * For new installations configure.pl tries to comply with the file
394 system hierarchy standard, which means all the configuration files
395 below /etc/BackupPC and log files go below /var/log/BackupPC.
397 * Added Slackware init.d script from Tony Nelson.
399 * Fixed error reporting when restore/archive fail to write the
400 request file to the client directory.
402 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
404 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
405 to DumpPreUserCmd etc.
407 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
409 * Jean-Michel Beuken reported several bugs in configure.pl in CVS 3.0.0.
411 * Old backup email warnings now ignore partials requested by Samuel Bancal
413 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
414 ignores any file starting with "." in the pc directory when
415 it is generating warnings about old/unused files/directories.
417 * Applied patch from Marc Prewitt to fix host queue order.
419 * Applied Lorenzo Cappelletti's it.pm patch.
421 * Applied Wander Winkelhorst's nl.pm patch.
423 * Applied Alberto Marconi's it.pm patch.
425 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
426 BackupPC_sendEmail to fix bug reported by Dale Renton.
428 * Added fixup of $ENV{REMOTE_USER} to lib/BackupPC/CGI/Lib.pm in the
429 case of using mod_authz_ldap; patch submitted by Alain Perrier.
431 * Added env LC_ALL=C to $Conf{TarClientCmd} and $Conf{TarClientRestoreCmd}
432 to avoid locale problems, suggested by Ludovic Drolez.
434 * Changed ping output parsing to pick out average rtt time, based
435 on patch from Ron Bickers.
437 * Removed leading "./" and top-level "./" directory from
438 zip archives generated by BackupPC_zipCreate. Reported
439 by Josh (hecktarzuli).
441 * BackupPC_tarCreate and BackupPC_zipCreate now allow "@"
442 in share names. Reported by Robert Waldner.
444 * NT_STATUS_INSUFF_SERVER_RESOURCES is now a fatal error for
445 smbclient transfers, suggested by Brian Shand.
447 * Changed bin/BackupPC_archiveHost to use /bin/csh instead of
448 /bin/sh. That way any errors in the pipeline are reported
449 via the exit status, instead of just the last.
451 * Added $Conf{EMailHeaders} for additional email headers, requested
452 by Ludovic Gasc. If the Content-Type charset is set to utf8 then
453 the body of the email is sent in utf8 coding.
455 * Made shareName argument regexp checking more general to allow parens.
457 * Added some debian init.d instructions to init.d/README from
460 * Documentation updates from Richard Ames, JP Vossen, Torsten Finke.
462 #------------------------------------------------------------------------
463 # Version 2.1.2pl2, 18 Jun 2006
464 #------------------------------------------------------------------------
466 * In conf/config.pl, changed --devices to -D in $Conf{RsyncArgs}
467 and $Conf{RsyncRestoreArgs} to fix "fileListReceive failed" and
468 "Can't open .../f%2f for empty output" errors with rsync 2.6.7+.
469 Fix proposed by Justin Pessa and Vincent Ho, and confirmed by
472 * Added patch from Michael (mna.news) to ignore "file is unchanged"
473 message from tar 1.15.x during incremental backups.
475 * Fixed creation of .rsrc directories in bin/BackupPC_tarExtract
476 when used with xtar on MacOS. Reported by Samuel Bancal and
477 Matthew Radey, who helped with debugging.
479 * Fixed bug in BackupPC_tarExtract for files >8GB in size whose
480 lengths are multiples of 256. Reported by Jamie Myers and
481 Marko Tukiainen, who both helped debugging the problem.
483 * Fixed bug in lib/BackupPC/Xfer/RsyncFileIO.pm that caused
484 incorrected deleted attributes to be set in directories
485 where one of the files had an rsync phase 1 retry during
486 an incremental. Reported by Tony Nelson.
488 #------------------------------------------------------------------------
489 # Version 2.1.2, 5 Sep 2005
490 #------------------------------------------------------------------------
492 * Fixed simple but serious bug in bin/BackupPC_tarCreate that prevented
493 hardlinks being saved correctly. Debugged by Michael (mna.news)
494 with several other people.
496 * Fixed serious bug in bin/BackupPC_dump reported/debugged by Dan Niles
497 that can happen when multiple full backups are deleted after
498 $Conf{FullKeepCnt} is changed.
500 * Changed lib/BackupPC/CGI/Lib.pm so that link to "$TopDir/conf/$host.pl"
501 is displayed if it exists. Patch from Andreas Vögele.
503 * Applied daemonize patch to bin/BackupPC from:
504 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=301057
506 * It's now a fatal error if $Conf{CompressLevel} is set, but
507 Compress::Zlib is not found. Before $Conf{CompressLevel} was
508 silently set to 0, which made all the backups uncompressed.
509 That meant the user never knew if they forget to install
510 Compress::Zlib but were expecting compression to be on.
512 * Finally increased $Conf{ClientTimeout} to 72000 (20 hours).
514 * Added sleep 1 in restart() function in init.d/src/gentoo-backuppc,
515 suggested by Jon Hood.
517 * Added $DestDir to the path of the CGI image directory in configure.pl.
518 Patch submitted by Andreas Vögele.
520 * Applied extensive patch to French translation from Frederic Lehobey.
522 * Minor change to Dutch language $Lang{Pool_Stat} from Wander Winkelhorst.
524 * Minor change to French language $Lang{EMailOutlookBackupMesg} and
525 $Lang{EMailOutlookBackupSubj} from Ludovic Gasc.
527 #------------------------------------------------------------------------
528 # Version 2.1.1, 13 Mar 2005
529 #------------------------------------------------------------------------
531 * Fixed bug in top-level restore using rsync XferMethod.
532 BackupPC::View was leaving an extra leading "/" at the start
533 of top-level directories, messing up the FileList sort order.
534 Reported and debugged by Gail Edwards.
536 * Added pathCreate() to BackupPC_tarExtract so that new directories
537 are created. Required for xtar on MacOSX since the virtual resource
538 fork directories (.rsrc) are not explicitly included in the tar
539 archive - just the files below .rsrc are.
541 * Changed $host.$bkupNum.tar$fileExt.* to $host.$bkupNum.tar$fileExt*
542 in $parCmd in bin/BackupPC_archiveHost.
544 * Fixed HostSortCompare() in BackupPC to correctly sort hosts so
545 those with the oldest backups get queued first.
547 * Changed test in BackupPC_sendEmail so that directories/files
548 starting with "." in $TopDir/pc are ignored, rather than
551 * Changed BackupPC_sendEmail to include NT_STATUS_FILE_LOCK_CONFLICT
552 in check for bad outlook files.
554 * Ensure that %Status and %StatusHost are empty if requesting
555 status on hosts in lib/BackupPC/CGI/Lib.pm GetStatusInfo().
556 Fixes problem with new hosts under mod_perl.
558 * Added images/icon-hardlink.gif so that hardlinks show file type icon.
560 #------------------------------------------------------------------------
561 # Version 2.1.0pl1, 15 Aug 2004
562 #------------------------------------------------------------------------
564 * Added fix to nl.pm from Lieven Bridts.
566 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
567 writes the status and shuts down.
569 * Changed BackupPC_nightly so that it doesn't call find() if the
570 directory doesn't exist. This avoids errors in certain versions
571 of perl. Reported by Bernd Rilling.
573 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
574 Reported by Tony Nelson and Jimmy Liang.
576 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
577 reported by Thomas Tempé.
579 * Added newline to "...skipping because of user requested delay..."
580 log message in BackupPC_dump. Reported by Wayne Scott.
582 * Added read file size error checking to BackupPC_tarCreate.
583 Reported by Brandon Evans.
585 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
586 compression is toggled on/off, a compressed backup doesn't link
587 to an uncompressed pool file (and an uncompressed backup doesn't
588 link to a compressed pool file). Reported by Brandon Evans.
590 * Updated documentation with new dirvish URL and a typo from
593 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
594 for hosts that have failed backups. Reported by Simon Kuhn.
596 #------------------------------------------------------------------------
597 # Version 2.1.0, 20 Jun 2004
598 #------------------------------------------------------------------------
600 * Added Dutch translation from Lieven Bridts, with tweaks from
603 * Added PC-specific config file read in CGI/Archive.pm. Patch
606 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
607 Patch from Pete Wenzel.
609 * Cosmetic changes to PC Summary and Log file language strings from
612 * BackupPC::Lib tries to be more careful when renaming the backups
613 file to backups.old. There have been reports of backups being
614 empty, perhaps when the BackupPC data file system fills up.
615 Now backups is not renamed to backups.old if backups is empty.
617 * BackupPC now closes stderr and stdout before renaming and
618 re-opening the log file.
620 * Pre/post backup/restore/archive commands now correctly set
621 "type" to either incr/full/restore/archive, and now cmdType
622 is the type of Pre/post backup/restore/archive command.
624 * BackupPC_archive correctly terminates archive processes on
627 * Updates to BackupPC_stnd.css with absolute font sizes instead
630 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
631 also ensures the full backup is older than the maximum age
632 expected from $Conf{FullPeriod}.
634 #------------------------------------------------------------------------
635 # Version 2.1.0beta2pl1, 30 May 2004
636 #------------------------------------------------------------------------
638 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
640 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
641 since zip file formats don't support earlier dates. Reported
644 * CGI restore via zip and tar now makes sure stderr is ignored
645 when BackupPC_tarCreate and BackupPC_zipCreate are run.
646 Previously any stderr output would get mixed in the archive,
647 corrupting it. Reported by Dan Niles.
649 #------------------------------------------------------------------------
650 # Version 2.1.0beta2, 23 May 2004
651 #------------------------------------------------------------------------
653 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
654 to every share, rather than just the first, in the case where
655 they are arrays and there are multiple shares. Suggested
658 * On the phase 2 retry pass with rsync, verify the cached checksums
659 if checksum caching is turned on. This will catch the case of
660 cached checksums being incorrectly appended to the compressed
661 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
662 so that cached checksums are verified with a selectable probability.
663 Also, increased File::RsyncP version number to 0.51.
665 * configure.pl now supports an optional batch mode. Command-line
666 options are used to specify all the information that configure.pl
667 needs. This is useful for building auto-install packages.
668 Also, configure.pl now includes pod documentation, so you can do
669 "perldoc configure.pl" to see all the command-line options.
670 Suggested, tested and tweaked by Stuart Herbert for possible
673 * At each wakeup, clients are now queued based on how old the most
674 recent backup is. Clients with errors are queued first, with
675 the oldest error times going first. The rest of the clients are
676 queued next, with the clients with the oldest backup going first.
677 Previously the clients were simply queued in alphabetic order.
678 Suggested by Mike Trisko and Tony Nelson.
680 * Added config parameter $Conf{PartialAgeMax} that controls whether
681 partials are saved at all, and if so, whether the partial will be
682 ignored at the next full backup if it is too old.
684 * BackupPC_tarExtract now allows empty archives without reporting
685 an error. Reported by Don Silvia.
687 * Removed Browse Backups link from Nav Bar in Archive Info display.
688 Reported by Ralph Paßgang.
690 * Fixed documentation display for regular users. Reported by Ralph Paßgang.
692 * Status and PC Summary now work for regular users and only show
693 that user's hosts. Server general status information only appears
694 for admins. Suggested by Ralph Paßgang.
696 * Moved the last three navigation-bar links (docs, FAQ and SF) to
697 a new config parameter $Conf{CgiNavBarLinks}. This allows
698 these links to be locally configured. Based on a patch
699 submitted by Ralph Paßgang.
701 * Allow the navigation bar search box to be disabled by
702 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
703 submitted by Ralph Paßgang.
705 * Updates to de.pm from Ralph Paßgang.
707 * Made the BackupPC icon a link to the SF BackupPC project page.
709 #------------------------------------------------------------------------
710 # Version 2.1.0beta1, 4 Apr 2004
711 #------------------------------------------------------------------------
713 * The CSS definition has been removed from the config.pl file and
714 is now a separate file, BackupPC_stnd.css. A new config variable,
715 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
716 Suggested by Ender Mathias.
718 * Fixed the filling of the host name select box for admins.
719 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
720 Reported by Doug Lytle.
722 * Cleaned up warning message for restore using rsync when checksum
723 caching is on, but when file didn't have cached checksums.
725 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
726 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
728 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
729 giving a significant performance improvement. Patch submitted by
732 * Allow several BackupPC_nightly processes to run in parallel based
733 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
734 traversal of the pool, reducing the overall run time for
737 * Allow BackupPC_nightly to split the pool traversal across several
738 nightly runs. This improves the running time per night, at the expense
739 of a slight increase in disk storage as unused pool files might not
740 be deleted for a couple of days. Controller by new config setting
741 $Conf{BackupPCNightlyPeriod}.
743 #------------------------------------------------------------------------
744 # Version 2.1.0beta0, 20 Mar 2004
745 #------------------------------------------------------------------------
747 * A failed full dump is now saved as a partial (incomplete) dump,
748 provided it includes some files. This can be used for browsing,
749 restoring etc, and will also form the basis of resuming full
750 dumps. Only one partial is kept, and it is removed as soon
751 as a successful full (or a new partial) is done.
753 * Added support for resuming a full dump for rsync. The partial
754 full is kept, and to resume an incremental is done against the
755 partial, and a full is done for the rest.
757 * Added support for Rsync checksum caching. Rsync checksum are
758 appended to the compressed pool files. This means that block
759 and file checksums do not need to be recomputed on the server
760 when using rsync. Requires a patch to rsync to support fixed
761 checksum seeds. This patch is included in the cygwin-rsyncd
762 release on http://backuppc.sourceforge.net.
764 * Major addition of Archive feature from Josh Marshall. Special
765 clients can be configured to be archive targets (eg: tape drives,
766 CD-R). Any subset of the backup clients can be selected and tar
767 archives are created, optionally compressed and split and written
768 to the output device. Logs are maintained and are browsable.
770 * Major changes from Ryan Kucera to add style sheets to the CGI
771 interface, allowing easy customization. Added new icons and
772 BackupPC logo. Numerous navigation improvements.
774 * Added directory history display to BackupPC_Admin, allowing the
775 user to quickly see which files changed between backups on a
778 * Added exponential expiry option for full dumps. This allows you
781 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
782 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
783 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
784 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
785 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
787 and so on. This allows you, for example, to keep 4 weekly fulls,
788 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
789 16 weeks, for roughly 1 year of history. This works by deleting
790 every other full as each expiry boundary is crossed. Suggested
793 * Added Italian language translation it.pm from Lorenzo Cappelletti.
795 * Major updates to language files for new features and tags changes.
796 Updated makeDist to do pedantic consistency checking of language
799 * Addition of administration options from Paul Lukins. Initial
800 page allows server to be started/stopped/reloaded. This still
801 needs some i18n work. Currently the server start/stop is
804 * Split BackupPC_Admin into a set of modules, one for each major action.
805 Each action is now a seperate module in lib/BackupPC/CGI.
807 * Allow the blackout period begin/end to span midnight. Adapted
808 from patch submitted by David Smith.
810 * Allow multiple blackout periods, with new config variable
811 $Conf{BlackoutPeriods} that replaces the old variables
812 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
813 $Conf{BlackoutWeekDays}. Based on patch submitted by
816 * Disabled alarms after forks to avoid timeouts in children that
817 do not reset their alarm. Prompted by ideas from James Leu.
819 * Added options for block size, buffer size and share wild-card to
820 BackupPC_tarCreate. Also added negative backup number options
821 that are relative to the last (so -1 is the last), suggested by
822 William McKee and Carl Soderstrom.
824 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
825 the user is more likely to see the error with BackupPC_tarCreate.
826 Reported by Paul Fox.
828 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
829 case it doesn't already exist.
831 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
832 SI Reasoning and Niranjan Ghate.
834 * Changed restore code so that option #1 (direct restore) can be
835 disabled if the restore command is undefined. Disabling direct
836 restore is necessary if the share is read-only. Suggested by
839 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
840 a decimal point or comma for international versions of Samba.
841 Patch submitted by Frank Gard.
843 * Browsing and directory history now sort the files in a
844 case-insensitive manner.
846 * Changed exec() syntax to allow executing commands whose path
849 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
850 is zero or undefined. The protects the existing backups in the
851 case of a bad config.pl file. Suggested by Christian Warden.
853 * Swapped the Server and Hosts sections on the Nav bar. Moved the
854 host search text box to the top of the hosts section. This was
855 done to move the variable-length part of the Nav bar (when all
856 hosts are displayed) to the bottom.
858 * Fixed a bug in tar restore related to how the common prefix path is
859 removed. Now ensure that the common path is at a directory boundary.
860 Reported by Patrick Neuner.
862 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
863 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
865 * Added Suse notes to init.d/README from Bruno Vernay.
867 * Added Apache 2 documentation fix from Michael Tuzi.
869 #------------------------------------------------------------------------
870 # Version 2.0.2, 6 Oct 2003
871 #------------------------------------------------------------------------
873 * Fixed stupid last-minute change in octal size conversion in
876 #-----------------------------------------------------------------------
877 # Version 2.0.1, 5 Oct 2003
878 #------------------------------------------------------------------------
880 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
881 files in BackupPC_tarCreate.
883 * Removed smbclient size repair in BackupPC_tarExtract for files
884 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
885 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
886 extacted using smbclient 2.2.x. If you have problems backing up
887 files whose size is between 2GB and 4GB using smbclient 2.2.x
888 you should upgrade smbclient to 3.0, since it now generates
891 * Replace PingClientPath with PingPath in configure.pl.
893 * Removed -T (taint mode) on binaries installed in configure.pl.
895 * Added support for smbclient from samba version 3.0.0.
897 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
900 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
901 if it is not defined. This allows the CGI interface to work
902 when AdminUsers = '*'. Reported by Quentin Arce.
904 * For SMB, code that detected files with a read-locked region (eg:
905 outlook .pst files), removed them and then tried to link with an
906 earlier version was broken. This code missed a step of mangling
907 the file names. This is now fixed. Reported by Pierre Bourgin.
909 * A backup of a share that has zero files is now considered
910 fatal. This is used to catch miscellaneous Xfer errors that
911 result in no files being backed up. A new config parameter
912 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
913 zero to turn off this check. Suggested by Guillaume Filion.
914 Additional change: this check only applies to a full dump.
916 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
917 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
918 smbclient.) Suggested by Guillaume Filion.
920 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
921 the dump is considered failed.
923 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
924 which just included the '/' directory and nothing below. Now it
925 does just --include '/', which should include everything.
928 * Add hostError to DumpPostUserCmd variable substitutions for both dump
931 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
932 makes BackupPC_dump -v work better.
934 * Don't allow browsing with ".." in directory in case a user tries
935 to trick BackupPC_Admin into displaying directories outside where
938 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
939 fixes large file (>2GB) bugs. Large file bugs reported by Steve
942 #------------------------------------------------------------------------
943 # Version 2.0.0, 14 Jun 2003
944 #------------------------------------------------------------------------
946 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
947 Added "no utf8" to all programs, and added binmode() to relevant
950 #------------------------------------------------------------------------
951 # Version 2.0.0beta3, 1 Jun 2003
952 #------------------------------------------------------------------------
954 * Several improvements to restore: cancel now reports the correct
955 message and cleans up correctly.
957 * Rsync with whitespace and wildcard excludes fixed by replacing
958 argList with argList+ in config.pl plus a fix to Lib.pm for
959 shell escaping array arguments.
961 * Fixed rsync restore for character and block special devices
962 (major and minor device numbers weren't correctly restored).
964 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
966 * (Re)-fixed "Bad command" in log file when restore via tar or zip
967 file download is done.
969 * Added untaint to exec in Lib.pm to avoid tainted errors.
971 * Applied additional tweak to hilight patch from Tim Demarest.
973 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
976 * Don't display RsyncdPasswd when displaying config.pl files.
978 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
979 which increases typical buffering from 4K to 16K-64K. This improves the
982 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
983 then a warning is printed.
985 #------------------------------------------------------------------------
986 # Version 2.0.0beta2, 11 May 2003
987 #------------------------------------------------------------------------
989 * Added German translation, provided by Manfred Herrmann.
991 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
993 * Fixed zip and tar file download from CGI under mod_perl. Reported
994 by Pierre Bourgin and Paul Lukins.
996 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
997 Reported by several users.
999 * Added -v option to BackupPC_dump for verbose output (useful when
1000 you run the command manually). Added messages for all exits.
1002 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
1003 now returns the first IP address that matches the subnet mask.
1004 Suggested by Tim Demarest.
1006 * Fixed BackupPC::View so the top-level directory is handled correctly.
1007 This allows the top-level share/directory to be restored via the
1008 CGI interface. Reported by several users.
1010 * Fixed RsyncFileIO failures on certain large files by replacing seek()
1011 with sysseek(). Reported by Manfred Herrmann.
1013 * Added configurable highlighting of PC status in the CGI summary
1014 screen; submitted by Tim Demarest.
1016 * Fixed command queue CGI display; submitted by Tim Demarest.
1018 * BackupPC_trashClean now logs an error if it can't remove all the
1019 trash and then goes back to sleep, rather than continually trying.
1021 * Moved correct user (uid) check into BackupPC::Lib so that all
1022 applications do a user check if $Cong{BackupPCUserVerify} is
1023 set. The avoids the risk of manually running BackupPC_dump as
1026 * Loss of blackout now applies to "host not found" as well as no ping.
1027 Reported by Dale Renton.
1029 * "Host not found" is now treated in a similar manner to "no ping".
1031 * Added suse-linux init.d script from Leon Letto.
1033 * Added Gentoo linux init.d script from Tim Demarest.
1035 * Applied additional i18n strings from GFK and the translation team.
1037 * Fixed option parsing so that getopts errors are reported and we exit.
1039 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
1041 #------------------------------------------------------------------------
1042 # Version 2.0.0beta1, 30 Mar 2003
1043 #------------------------------------------------------------------------
1045 * Added Spanish translation es.pm from Javier Gonzalez.
1047 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
1048 when directories were selected in a certain order.
1050 * Fixed BackupPC::PoolWrite so that it can recover when the initial
1051 file size is wrong. This is needed since rsync could write a file
1052 whose size is different from the initial size returned in the
1053 file list when that file is updated while rsync is running.
1055 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
1056 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
1057 helps, but it should be benign. See:
1058 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
1060 #------------------------------------------------------------------------
1061 # Version 2.0.0beta0, 23 Feb 2003
1062 #------------------------------------------------------------------------
1064 * Support for rsync and rsyncd backup and restore. Changes to
1065 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
1066 and BackupPC::Xfer::RsyncFileIO.
1068 * Added internationalization (i18n) code from Xavier Nicollet,
1069 with additions from Guillaume Filion. Voila! BackupPC_Admin
1070 now supports English and French, and adding more languages is
1071 now easy. New config paramater $Conf{Language} sets the language.
1073 * Added optional user-defined pre/post dump/restore commands, allowing
1074 things like database shutdown/startup for dumps.
1076 * Changed the way hosts are found.
1078 * Added $Conf{ClientNameAlias}, which allows the name of the physical
1079 client machine to be set. This allows several different backup
1080 "hosts" to all refer to the same physical machine, which is
1081 convenient if several different types of data need to be backed
1082 up, or if different parameters are needed for different parts of
1085 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
1086 $Conf{NmbLookupCmd} allowing all these commands to be fully
1087 configured. Also, all commands can also now be fragments of
1090 * Moved all smbclient commands into the config.pl file so the specific
1091 arguments can be customized. New config parameters are
1092 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
1093 $Conf{SmbClientRestoreCmd}.
1095 * Added new BackupPC::View module that creates views of backups
1096 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
1097 and BackupPC_tarCreate to use BackupPC::View. This removes lots
1098 of merging and mangling code from the higher-level code.
1100 * Added code from Toby Johnson that allows additional users to be
1101 specified in the hosts file; these users can also view/start/stop
1102 and restore backups for that host. Also added a new config
1103 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
1104 be listed in the left nav bar for admins.
1106 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
1107 the maximum number of hardlinks per file in the pool. If a file
1108 ever gets to this number of links a new pool file is created to
1109 handle additional links.
1111 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
1112 modules to be loaded.
1114 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
1115 allow language-specific default messages to be overridden.
1117 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
1118 files to be represented in the attrib file correctly.
1120 * Added support for environment variable BPC_SMB_PASSWD, which is the
1121 client's smb password. This overrides the old environment variable
1124 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
1126 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
1127 handle files with trailing spaces.
1129 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
1130 to ignore multiple signals of the same type.
1132 * Added reporting of the largest number of hardlinks in the pool to the
1135 * Adding reporting of syntax errors in the per-PC config.pl file.
1137 * Updated BackupPC_sendEmail to handle language-specific email messages.
1139 * Allow client (host) names to contain spaces. Spaces in host names
1140 need to be escaped via "\" in the hosts file. The user of spaces in
1141 host names is discouraged, but they should work. One feature that
1142 doesn't work with host names that contain spaces is the highlighting
1143 of that name in the log file display in the CGI interface. There are
1144 no plans to fix this.
1146 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
1148 * Fixed all open() calls to use 3 argument form to fix handling of file
1149 names with trailing whitespace. Also fixed CGI interface so these
1150 file names are displayed correctly.
1152 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
1153 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
1154 Reported by Pascal Schelcher. Fixed similar problem reported by
1157 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
1158 suggested by Tim Demarest.
1160 #------------------------------------------------------------------------
1161 # Version 1.5.0, 2 Aug 2002
1162 #------------------------------------------------------------------------
1164 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
1165 option instead of --newer-mtime. Also removed --atime-preserve from
1166 $Conf{TarClientCmd}. This makes the default settings work better
1169 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
1170 so it can correctly warn the user to stop it before upgrading. Reported
1173 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
1174 Reported by Guillaume Filion.
1176 * Added LDAP setup to documentation from David Holland.
1178 * Tar.pm now adds a "." to file paths that start with "/", so that all
1179 tar paths are relative. From Ludovic Drolez.
1181 #------------------------------------------------------------------------
1182 # Version 1.5.0beta0, 30 Jun 2002
1183 #------------------------------------------------------------------------
1185 * A full set of restore options is now supported, including direct
1186 restore via smbclient or tar or downloading a zip or tar file.
1188 * Major additions to CGI script to support better directory navigation,
1189 restore features and mod_perl. Also, file downloads from the CGI
1190 interface now correctly preserve the file name and provide the
1191 correct Content-Type for the most common types of files. Improved
1192 directory navigation was contributed by Ryan Kucera.
1194 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
1195 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
1196 create a zip archive of any portion of a backup.
1198 * Substantial additions to BackupPC_tarCreate to support restore,
1199 including modifying path names, handling hardlinks, fixing
1200 support of old backups without attributes (pre-v1.4.0). Plus
1201 BackupPC_tarCreate is now an offical part of the release.
1202 (Lack of support for hardlinks was reported by John Stanley.)
1204 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
1207 * A unix domain socket is now used for communication between the CGI
1208 interface and BackupPC. The original TCP socket is optional. Sockets
1209 are correctly re-initialized if config.pl is updated with new socket
1212 * For improved security messages over the unix or TCP socket are protected
1213 via an MD5 digest based on a shared secret, a sequence number, a time
1214 stamp and a unique per-connection number.
1216 * Additions to configure.pl to support install of directory navigation
1219 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
1220 were set to a single string or list (in v1.4.0 only the case of
1221 hash worked correctly). Reported by Phillip Bertolus.
1223 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
1224 client always subject to blackout, matching the comments in config.pl.
1225 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
1226 reported by Pascal Schelcher.
1228 * Fixed byte and file totals for tar backups, reported by several users.
1230 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
1231 suggested by Erminio Baranzini.
1233 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
1234 well as shell escaping of tar arguments.
1236 * Fixed entity encoding of 8-bit characters in the CGI interface.
1238 * Added optional CGI headers in $Conf{CgiHeaders} that by default
1239 is set to a no-cache pragma. Suggested by Benno Zuure.
1241 #------------------------------------------------------------------------
1242 # Version 1.4.0, 16 Mar 2002
1243 #------------------------------------------------------------------------
1245 * BackupPC now supports tar (in addition to smb) for extracting host
1246 data. This is the most convenient option for linux/unix hosts.
1247 Tar can be configured to run over ssh, rsh or to backup a local
1248 nfs mount from the host.
1250 * Support for special files, including symbolic links, fifo, character
1251 and block device files has been added, so that all native linux/unix
1252 file types can be correctly backed up when using tar transport.
1253 Special files are all stored as regular files and the type attributes
1254 are used to remember the original file type.
1256 * All unix file attributes are now saved (and pooled when possible).
1257 This includes user and group ownership, permissions, and modification
1258 time. Smbclient also does a reasonable job of emulating unix
1259 permissions (such as mtime), and these attributes get saved too.
1261 * The new default is to not fill incremental dumps. configure.pl
1262 automatically sets $Conf{IncrFill} to 0. The default was 1
1263 (incrementals were filled with hardlinks). Since the CGI
1264 script does filling at browsing time, there is no need to
1265 fill incremental dumps.
1267 * Backup file names are now stored in "mangled" form. Each node of a
1268 path is preceded by "f", and special characters (\n, \r, % and /) are
1269 URI-encoded as "%xx", where xx is the ascii character's hex value. So
1270 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
1271 was done mainly so meta-data could be stored alongside the backup
1272 files without name collisions. In particular, the attributes for the
1273 files in a directory are stored in a file called "attrib", and
1274 mangling avoids file name collisions (I discarded the idea of having
1275 a duplicate directory tree for every backup just to store the
1276 attributes). Other meta-data (eg: rsync checksums) could be stored in
1277 file names preceded by, eg, "c". There are two other benefits to
1278 mangling: the share name might contain "/" (eg: "/home/craig" for tar
1279 transport), and I wanted that represented as a single level in the
1280 storage tree. Secondly, as files are written to NewFileList for later
1281 processing by BackupPC_link, embedded newlines in the file's path
1282 will cause problems which are avoided by mangling.
1284 The CGI script undoes the mangling, so it is invisibe to the user.
1285 Of course, old (unmangled) backups are still supported by the CGI
1288 * Various changes to the CGI interface, BackupPC_Admin:
1290 + Added button that allows users to manually start a full dump in
1291 addition to the existing incremental dump.
1293 + Added display of file attributes when browsing backups.
1295 + Added an optional holdoff time specified by the user when canceling
1296 a backup. BackupPC will not attempt any new backups for at least the
1297 specified time. This holdoff time can be changed whether or not a
1300 + Added supports for file mangling, and correct merging of unfilled
1301 backups from mangled or unmangled (and compressed or uncompressed)
1302 fulls when browsing or restoring.
1304 + Only displays a "Start Incr Backup" button if there are already some
1307 + For DHCP hosts, when a user tries to manually start a backup, add
1308 a check for the netbios name of both the host the request came
1309 from (REMOTE_ADDR) and the last known DHCP address for that host
1310 to see if either address matches the host. If not, an error
1311 message is display. The previous behavior was that only requests
1312 from the client itself succeeded, and requests from other machines
1315 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
1316 is 1.4.0. The first digit is for major new releases, the middle digit
1317 is for significant feature releases and improvements, and the last
1318 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
1319 and 1.03 as 1.0.0, ..., 1.3.0.
1321 * BackupPC and the CGI script BackupPC_Admin now check that the effective
1322 user id is correct to avoid accidentally launching BackupPC as the
1323 wrong user or detecting CGI configuration problems. This behavior
1324 can be turned off using the $Conf{BackupPCUserVerify} option.
1326 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
1327 support generic names for both smb and tar transport methods. The
1328 CGI script checks for old names for backward compatibility.
1330 * Major changed to Backup_dump to support new tar transport. All transport
1331 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
1334 * Added workaround for a bug in Samba's smbclient for files between 2GB
1335 and 4GB. The file size in the tar header is incorrect. This allows
1336 files up to 4GB to work with smbclient, rather than 2GB. To support
1337 files larger than 2GB you must make sure perl is compiled with the
1338 uselargefiles option (use "perl -V | egrep largefiles" to check) and
1339 the pool directory must be on a file system that supports large files.
1341 * Moved the pool writing code into a module BackupPC::PoolWrite. This
1342 allows the clever file pool checking (digest, uncompressing, comparing
1343 etc with minimum disk IO) to be used easily in multiple places (eg: it
1344 is now used for writing attribute files so they can be pooled).
1346 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
1348 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
1349 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
1350 on one user's machine was world writable and perl -T correctly
1351 complained about it.
1353 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
1354 Thanks to Kyle Amon for sending the fix. Decided to move the
1355 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
1356 now configure.pl tries to come up with a sensible default based on
1359 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
1360 share name (eg: C$). Thanks to Jules Agee for this fix. Also
1361 changed the default config.pl so that single quotes are used
1362 everywhere so that people don't get tripped up putting '$' inside
1363 double-quoted strings.
1365 #------------------------------------------------------------------------
1366 # Version 1.03, 9 Dec 2001
1367 #------------------------------------------------------------------------
1369 * BackupPC now has full support for compression. There are now two
1370 pool areas, the original pool for uncompressed files, and cpool for
1371 compressed files. The compression is done by Compress::Zlib.
1372 Compression reduces the pool disk usage by around 40%, although your
1373 mileage may vary. Compression is optional and can also be specified on
1374 a per-PC basis (although this will cost more pool storage since many
1375 backup files will have to be stored in both compressed and
1378 * A new script, BackupPC_compressPool, can be run to compress the entire
1379 pool. This is used once to migrate all the pool data from uncompressed
1380 to compressed on existing installations. Read the documentation
1381 (Installing BackupPC/Compressing an existing pool) before running
1382 BackupPC_compressPool!
1384 Alternatively, compression can simply be turned on and all new backups
1385 will be compressed. Both old (uncompressed) and new (compressed)
1386 backups can be browsed and viewed. Eventually, the old backups will
1387 expire and all the pool data will be compressed. However, until the
1388 old backups expire, this approach could require 60% or more additional
1389 pool storage space to store both uncompressed and compressed versions
1390 of the backup files.
1392 * Significant improvements to the cgi interface, BackupPC_Admin:
1394 - much better layout navigation
1395 - handles compressed backup files and compressed log files
1396 - handles unfilled incremental dumps
1397 - better backup directory browsing navigation
1398 - reports compression statistics
1399 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
1400 - Additional customization with $Conf{CgiHeaderFontType},
1401 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
1402 $Conf{CgiHeaderBgColor}.
1404 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
1405 file and queues the PCs itself. Like config.pl, BackupPC will
1406 re-read the hosts file on each wakeup if its modification time
1407 changes, or upon a SIGHUP. This also makes for better behavior
1408 when adding a host: if you add hosts, simply send a SIGHUP to
1409 BackupPC or wait for the next wakeup.
1411 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
1413 * BackupPC_dump keeps track of compressed file sizes so that compression
1414 statistics can be reported by the cgi interface.
1416 * Aging of old log files now handles compressed log files (.z extension).
1418 * Added configuration option $Conf{IncrFill} to specify whether
1419 incremental dumps should be filled in. Old behavior was that
1420 filling was on. Now it's optional. See config.pl for more
1423 * BackupPC_nightly now cleans and generates statistics for both
1424 the uncompressed pool and compressed pool (cpool).
1426 * Added new utility script BackupPC_zcat that can be used to
1427 uncompresses BackupPC files.
1429 * configure.pl offers various options related to compression,
1430 depending upon whether this is a new install or upgrade,
1431 and whether or not Compress::Zlib is installed.
1433 * configure.pl now makes a backup copy of config.pl before
1434 config.pl is updated.
1436 * added three new fields to the backups file to handle optional
1437 filling and compression stats.
1439 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
1440 on each dhcp host once each night to verify that very old backups are
1441 expired. This ensures that very old backups are expired even if
1442 the dhcp host has not been on the network for a long time.
1444 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
1445 even if compression was off. Thanks to Steve Holmes for reporting
1448 * fixed bug that caused a BackupPC queue to get blocked when a backup
1449 cancel attempt was made during the BackupPC_link phase.
1451 #------------------------------------------------------------------------
1452 # Version 1.02, 28 Oct 2001.
1453 #------------------------------------------------------------------------
1455 * Added new script BackupPC_tarExtract to extract the smbclient tar
1456 archive. This reduces disk writes by perhaps 90-95% and disk reads by
1457 50%. Previously, tar was used to extract and write everything to disk.
1458 Then BackupPC_dump would read enough of each file to compute the MD5
1459 digest, and then compare the full file with candidate pool files. So
1460 for each 1MB file that matches a single file in the pool, there would
1461 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
1463 BackupPC_tarExtract instead extracts the archive using a 1MB memory
1464 buffer. This allows the MD5 digest to be computed without touching the
1465 disk. Next, any potential pool file compares are done by comparing the
1466 pool file against the incoming tar data in memory, which only requires
1467 the pool file to be read. So for each 1MB file that matches a single
1468 file in the pool, there are now no disk writes, and only 1MB of reads.
1469 BackupPC_tarExtract handles arbitrary size files and repeated
1470 potential pool matches. If the incoming file doesn't match the pool
1471 then it is written to disk (once the pool is mature this happens maybe
1474 * Substantial changes to BackupPC_dump:
1476 + BackupPC_tarExtract is now used in place of tar.
1478 + BackupPC_dump now reads the output from both smbclient and
1479 BackupPC_tarExtract and merges them into SmbLOG.
1481 + Named pipes are no longer used to connect smbclient to tar
1482 (now BackupPC_tarExtract). Regular pipes are used instead.
1483 This avoids the need to system mknod or mkfifo.
1485 + Locked files on the client that can't be read by smbclient
1486 previously were filled with 0x0 bytes by smbclient, meaning
1487 tar extracted a useless file filled with 0x0 bytes. Now,
1488 BackupPC_dump watches the output of smbclient and removes
1489 any files that smbclient couldn't read. This avoids storing
1490 useless files. It tries to replace such files with a hard link
1491 to a previous dump. These actions appear in the log file.
1493 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
1494 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
1495 reading and writing compressed and regular files and provides all the
1496 hooks for compression support in BackupPC (should be supported in next
1497 version). BackupPC::FileIO also does efficient writing of files that
1498 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
1499 helpful when smbclient reads a locked file, and it fills the tar
1500 output with a file of the correct size but all 0x0. Such files will be
1501 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
1502 writes such files efficiently (as sparse files), meaning just a few
1503 blocks of disk space will be needed even if the file is large.
1505 * alive/dead counting for blackout now works correctly for DHCP hosts.
1507 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
1508 killed and restarted with backups running.
1510 * added extra non blocking select() in BackupPC to make sure the socket
1513 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1515 * Updated BackupPC_sendEmail to correctly parse the locked file
1516 error from 2.2.1a smbclient, so that missing Outlook file emails
1517 can be correctly sent.
1519 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1520 hostname read from the hosts file.
1522 * BackupPC_Admin provides general summary when the host name is empty.
1524 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1526 * configure.pl complains if BackupPC is already running, reminding you
1527 to stop it before upgrading.
1529 * updated documentation, and fixed auto-insertion of config.pl into
1530 BackupPC.pod (previously the last config parameter was left out of
1533 #------------------------------------------------------------------------
1534 # Version 1.01, 30 Sep 2001
1535 #------------------------------------------------------------------------
1537 * Documentation cleanup in README, doc/BackupPC.pod, conf/config.pl.
1539 * BackupPC_sendMail now reads the optional per-PC config file, allowing
1540 email configuration parameters to be set on a per-PC basis.
1542 * Removed the unused 4096-length MD5 digest code in lib/BackupPC/Lib.pm.
