22 #------------------------------------------------------------------------
24 * When there is an existing partial, a new partials is only saved
25 if it has more files than the existing partial. Requested by
28 * Fixed handling of $Conf{BackupFilesExclude} for tar XferMethod.
29 Patch supplied by Frans Pop.
31 * Fixed numeric column sorting in host summary table, reported by
34 * Fixed host CGI editor so it creates the new host's config.pl file
35 using the lower-case host name, since host names are mapped to
36 lower case when they are read from the hosts file. Reported by
39 * Applied documentation patches from Frans Pop.
41 * Added Polish translation from Semper.
43 * Fixed BackupPC_nightly reporting of repeated pool file hashes,
46 * Add run-time check that IO::Dirent is functioning correctly.
48 #------------------------------------------------------------------------
49 # Version 3.1.0beta0, 3 Sep 2007
50 #------------------------------------------------------------------------
52 * Added new script BackupPC_archiveStart that allows command-line
53 starting of archives. Based on script written by Sergey Kovzik,
54 which in turn was based on an earlier version by Holger Parplies.
56 * Added Simplified Chinese CGI translation from Youlin Feng,
57 plus fixed a couple of cases where utf8 share names were
58 not displayed correctly.
60 * Added sorting by column feature to host summary table in CGI
61 interface. Implemented by Jeremy Tietsort.
63 * Added optional support for IO::Dirent which allows inode information
64 to be extracted from the dirent directory structure. This allows
65 BackupPC to order some directory operations by inode, which on
66 some file systems (eg: ext3) can results in a 20-30% performance
67 gain. On other file systems there is no real improvement. This
68 optimization is turned on automatically if IO::Dirent is installed.
70 * Added some performance improvements to BackupPC::Xfer::RsyncFileIO
71 for the case of small files with cached checksums.
73 * Added check to BackupPC at startup that $TopDir can support
74 hardlinks. Also added check to BackupPC_dump that a hardlink
75 below $TopDir/pc/HOST can be made to below $TopDir/cpool.
76 Also added the need for a hard-link capable file system to
77 the documentation. Suggested by Nils Breunese.
79 * Added FreeBSD init.d file provided by Gabriel Rossetti.
81 * Added -l and -L options to BackupPC_tarCreate so that
82 provide a file list (without creating the archive).
85 * Made the default charset for BackupPC_zipCreate cp1252, which
86 appears to work correctly with WinZip. Unfortunately there is
87 no clear standard for charset encoding in zip files.
89 * Added support so that pre-3.0 backups with non-utf8 charsets
90 can be viewed and restored correctly. A new config variable
91 $Conf{ClientCharsetLegacy} specifies the charset used to
92 encode file names in legacy backups. This is only relevant
93 if you are trying to view or restore a backup made with
94 BackupPC 2.x and some of the file names have non-ascii
97 * Added setting of the environment variable BPC_REQUSER to
98 the requesting user name in BackupPC prior to fork(), so
99 each child process inherits the value. Submitted by
102 * Fixed bug in rsync incrementals that happens on particular
103 file names when a file being backed up fails in both rsync
104 phases. Reported by Dan Smisko.
106 * Fixed single-restore file name charsets for IE, reported by
109 * Fixed makeDist so that the --config-dir option to configure.pl
110 works correctly. Reported by Randy Barlow, Tony Shadwick and others.
112 * Removed ConfDir from config editor (since it is hardcoded in
113 lib/BackupPC/Lib.pm). Also made TopDir and LogDir only visible
114 if useFHS (for non-FHS they are hardcoded in lib/BackupPC/Lib.pm).
116 * Applied patch from Holger Parplies that fixes cleanup of early abort
119 * Applied small patch from Sergey to lib/BackupPC/Xfer/Tar.pm that makes
120 it ignore "socket ignored" error on incrementals.
122 * Applied small patch from Sergey to bin/BackupPC_archiveHost.
124 * Changed BackupPC_sendEmail so that summary admin email doesn't
125 include errors from hosts that have $Conf{BackupsDisable} set.
126 Reported by James Kyle. Also, per-user email is now disabled
127 when $Conf{BackupsDisable} is set.
129 * Added RsyncdUserName to the config editor. Reported by Vicent Roca Daniel.
131 * $Conf{IncrLevels} is now defaulted if it is not defined.
133 * configure.pl clears $Conf{ParPath} if it doesn't point to a valid
136 * Added documentation for BackupPC_tarPCCopy, including use of -P option
137 to tar suggested by Daniel Berteaud.
139 * Config editor now removes white space at start of exec path.
140 Reported by Christoph Iwasjuta.
142 * CgiDateFormatMMDD == 2 gives a YYYY-MM-DD format for CGI dates,
145 #------------------------------------------------------------------------
146 # Version 3.0.0, 28 Jan 2007
147 #------------------------------------------------------------------------
149 * BackupPC_sendEmail now correctly sends admin email if backups
150 were skipped because the disk was too full, reported by Dan
153 * BackupPC_Admin now uses $Conf{UmaskMode}, so config.pl files
154 written by the editor have more restrictive permissions.
155 Reported by Tim Massey.
157 * Host summary now shows active backups on disabled hosts,
160 * Fixed host LOG link and LOG list order, reported by Tim Massey.
162 * Moved Encode.pm version check to start of configure.pl so it
163 produces a useful error message if Encode.pm is too old.
165 * Fixed hrefs to configuration documentation to handle changes
166 in the way perl generates the anchors. Reported by Philip
169 * Host name links in LOG files now allow "." in the host name.
170 Reported by Jean-Michel Beuken.
172 * Fixes to lib/BackupPC/Xfer/Tar.pm for tar 1.16: allow 1
173 (ie: 256) as a successful exit status and match "Total
174 bytes read" message for restores. First reported by
175 Torsten Sadowski and debugged by Ralf Gross and Holger
178 #------------------------------------------------------------------------
179 # Version 3.0.0beta3, 3 Dec 2006
180 #------------------------------------------------------------------------
182 * Removed default paths from conf/config.pl so configure.pl will
183 determine the correct ones at install time. Avoids problem of
184 the config editor complaining about bad executable paths the
185 first time you use it.
187 * Changed first byte of compressed files with rsync checksums appended
188 to 0xd7 to allow correct protocol_version >= 27 md4 checksums to be
189 written. Old cached checksum files have a first byte 0xd6 and are
190 now considered to be uncached. They will be automatically updated
191 as needed. This avoids the cached checksum warnings in beta2.
193 * BackupPC_tarPCCopy now handles all file types correctly. Reported
196 * Fixed BackupPC_nightly to finish pending deletes before renaming
199 * Fixes for rsync restore where hardlink is to file outside of the
200 top-level restore directory. Reported by George Avrunin, who helped
203 * Fixes for checksum mismatch on restore for certain file sizes.
204 Reported by George Avrunin and others.
206 * Fix for config.pl writing code to handle multi-line expressions.
207 Reported by David Relson and others.
209 * Fix for CGI editor when deleting hash entries whose keys are
210 non alphanumeric. Report by David Relson and Aaron Ciarlotta.
212 * Two fixes to configure.pl from Andreas Vögele.
214 #------------------------------------------------------------------------
215 # Version 3.0.0beta2, 18 Nov 2006
216 #------------------------------------------------------------------------
218 * Fix for final md4 digest check on rsync transfers >= 512MB when protocol
219 version >= 27 and checksums are not cached. Reported by Garith Dugmore
222 * Config Editor "Save" button is now always visible, but greyed out
223 until there are changes to save.
225 * Config editor allows other tabs to be selected when there is an
226 error, which allows you to fix an error (eg: missing binary) in
227 an exiting config file. Errors are now displayed at the top of
228 the page in addition to next to the erroneous setting.
230 * configure.pl checks version of Encode.pm. Reported by Chris Stone.
232 * Several fixes to bin/BackupPC_fixupBackupSummary from Stian Jordet.
234 * Fixed config.pl editor writing to solve bug with multi-line text
235 strings ending in newline. Reported and root caused by Les Stott
238 * Fixed error recovery case in BackupPC::PoolWrite, reported by
241 * Fixed table width in backup browsing to avoid Firefox layout anomoly,
242 provided by Jono Woodhouse.
244 * CSS file updates from Jono Woodhouse. Prior (v2) version is included
245 as BackupPC_stnd_orig.css in case people prefer the old skin.
247 * More compact host summary, including disabled host indication,
250 * New directory/file/hardlink and symlink image icons from Sean Cameron
251 and Jono Woodhouse, making directory browse more compact.
253 * BackupPC.pid is now world readable, suggested by Casper Thomsen.
255 * Reordered the Server navigation bar links, suggested by David Relson.
257 * Fixed typos in init.d/src/gentoo-backuppc, configure.pl and config.pl
258 reported by David Relson.
260 #------------------------------------------------------------------------
261 # Version 3.0.0beta1, 30 Jul 2006
262 #------------------------------------------------------------------------
264 * Fixed several Xfer charset conversions.
266 * Added some CGI utf8 conversions from Rodrigo Real and Vincent
269 * Rsync transfers now correctly handle file names with \n or \r.
271 * Host name is forced to lower case, to match 2.x.
273 * Fixed LOG file naming in BackupPC_restore and BackupPC_archive.
275 * GFK applied fr.pm corrections from Nicolas Stransky.
277 * Updated init.d/src scripts for FHS (ie: replaced __TOPDIR__/log
278 with __LOGDIR__ and __TOPDIR__/conf with __CONFDIR__). Patch
279 provided by Rodrigo Real.
281 * Added --log-dir and --conf-dir options to configure.pl.
282 Reported by Vincent Fleuranceau.
284 * Updated File::RsyncP version check in configure.pl, reported
285 by Vincent Fleuranceau. Changed File::RsyncP version to 0.64.
287 #------------------------------------------------------------------------
288 # Version 3.0.0beta0, 11 Jul 2006
289 #------------------------------------------------------------------------
291 * Added configuration and host CGI editor.
293 * Added rsync hardlink support. Requires latest version of
296 * Decoupled BackupPC_dump from BackupPC_nightly by making
297 asynchronous file linking/delete robust to race conditions.
298 Now only BackupPC_nightly and BackupPC_link are mutually
299 exclusive so only one runs at a time, and BackupPC_dump and
300 BackupPC_restore can run anytime.
302 * Added support for multi-level incrementals. In the style of dump(1),
303 the level of each incremental can be specified. Each incremental
304 backups up everything since the most recent backup of a lower level
305 (fulls are always level 0). Previous behavior was all incrementals
306 were level 1, meaning they backed up everything since the last full
307 (level 0). Default configuration is all incrementals are level 1.
309 * Server file names are now in utf8 and optional conversion
310 to/from client name charsets can be configured. All CGI pages
311 now use the utf8 charset.
313 * Backup metadata is now additionally saved to pc/HOST/nnn/backupInfo,
314 in addition to pc/HOST/backups. In case pc/HOST/backups gets trashed,
315 then a new script BackupPC_fixupBackupSummary can read the per-backup
316 metadata from pc/HOST/nnn/backupInfo and reconstruct the backups file.
317 Roberto Moreno also pointed out an early error in the CVS version.
319 * Added Storage module and Storage::Text which localizes all the
320 text data file reading/writing (eg: backups, restores, archives
321 and config.pl files). Added read verify after all write
322 operations for robustness. Additional backends (eg: SQL)
323 can be added in the future as new subclasses of the Storage
326 * Added Config module, and Config::Meta that contains meta data
327 about configuration parameters.
329 * Added RSS support from Rich Duzenbury.
331 * Translations of new 3.0 language strings from Guillaume Filion,
332 Reginaldo Ferreira, Ralph Passgang, Lieven Bridts, Guus Houtzager,
335 * Added optional checking of exit status of Dump/Restore/Archive Pre/Post
336 UserCmd, requested by Kiko Jover, Matthias Bertschy and others.
338 * For new installations configure.pl tries to comply with the file
339 system hierarchy standard, which means all the configuration files
340 below /etc/BackupPC and log files go below /var/log/BackupPC.
342 * Added Slackware init.d script from Tony Nelson.
344 * Fixed error reporting when restore/archive fail to write the
345 request file to the client directory.
347 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
349 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
350 to DumpPreUserCmd etc.
352 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
354 * Jean-Michel Beuken reported several bugs in configure.pl in CVS 3.0.0.
356 * Old backup email warnings now ignore partials requested by Samuel Bancal
358 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
359 ignores any file starting with "." in the pc directory when
360 it is generating warnings about old/unused files/directories.
362 * Applied patch from Marc Prewitt to fix host queue order.
364 * Applied Lorenzo Cappelletti's it.pm patch.
366 * Applied Wander Winkelhorst's nl.pm patch.
368 * Applied Alberto Marconi's it.pm patch.
370 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
371 BackupPC_sendEmail to fix bug reported by Dale Renton.
373 * Added fixup of $ENV{REMOTE_USER} to lib/BackupPC/CGI/Lib.pm in the
374 case of using mod_authz_ldap; patch submitted by Alain Perrier.
376 * Added env LC_ALL=C to $Conf{TarClientCmd} and $Conf{TarClientRestoreCmd}
377 to avoid locale problems, suggested by Ludovic Drolez.
379 * Changed ping output parsing to pick out average rtt time, based
380 on patch from Ron Bickers.
382 * Removed leading "./" and top-level "./" directory from
383 zip archives generated by BackupPC_zipCreate. Reported
384 by Josh (hecktarzuli).
386 * BackupPC_tarCreate and BackupPC_zipCreate now allow "@"
387 in share names. Reported by Robert Waldner.
389 * NT_STATUS_INSUFF_SERVER_RESOURCES is now a fatal error for
390 smbclient transfers, suggested by Brian Shand.
392 * Changed bin/BackupPC_archiveHost to use /bin/csh instead of
393 /bin/sh. That way any errors in the pipeline are reported
394 via the exit status, instead of just the last.
396 * Added $Conf{EMailHeaders} for additional email headers, requested
397 by Ludovic Gasc. If the Content-Type charset is set to utf8 then
398 the body of the email is sent in utf8 coding.
400 * Made shareName argument regexp checking more general to allow parens.
402 * Added some debian init.d instructions to init.d/README from
405 * Documentation updates from Richard Ames, JP Vossen, Torsten Finke.
407 #------------------------------------------------------------------------
408 # Version 2.1.2pl2, 18 Jun 2006
409 #------------------------------------------------------------------------
411 * In conf/config.pl, changed --devices to -D in $Conf{RsyncArgs}
412 and $Conf{RsyncRestoreArgs} to fix "fileListReceive failed" and
413 "Can't open .../f%2f for empty output" errors with rsync 2.6.7+.
414 Fix proposed by Justin Pessa and Vincent Ho, and confirmed by
417 * Added patch from Michael (mna.news) to ignore "file is unchanged"
418 message from tar 1.15.x during incremental backups.
420 * Fixed creation of .rsrc directories in bin/BackupPC_tarExtract
421 when used with xtar on MacOS. Reported by Samuel Bancal and
422 Matthew Radey, who helped with debugging.
424 * Fixed bug in BackupPC_tarExtract for files >8GB in size whose
425 lengths are multiples of 256. Reported by Jamie Myers and
426 Marko Tukiainen, who both helped debugging the problem.
428 * Fixed bug in lib/BackupPC/Xfer/RsyncFileIO.pm that caused
429 incorrected deleted attributes to be set in directories
430 where one of the files had an rsync phase 1 retry during
431 an incremental. Reported by Tony Nelson.
433 #------------------------------------------------------------------------
434 # Version 2.1.2, 5 Sep 2005
435 #------------------------------------------------------------------------
437 * Fixed simple but serious bug in bin/BackupPC_tarCreate that prevented
438 hardlinks being saved correctly. Debugged by Michael (mna.news)
439 with several other people.
441 * Fixed serious bug in bin/BackupPC_dump reported/debugged by Dan Niles
442 that can happen when multiple full backups are deleted after
443 $Conf{FullKeepCnt} is changed.
445 * Changed lib/BackupPC/CGI/Lib.pm so that link to "$TopDir/conf/$host.pl"
446 is displayed if it exists. Patch from Andreas Vögele.
448 * Applied daemonize patch to bin/BackupPC from:
449 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=301057
451 * It's now a fatal error if $Conf{CompressLevel} is set, but
452 Compress::Zlib is not found. Before $Conf{CompressLevel} was
453 silently set to 0, which made all the backups uncompressed.
454 That meant the user never knew if they forget to install
455 Compress::Zlib but were expecting compression to be on.
457 * Finally increased $Conf{ClientTimeout} to 72000 (20 hours).
459 * Added sleep 1 in restart() function in init.d/src/gentoo-backuppc,
460 suggested by Jon Hood.
462 * Added $DestDir to the path of the CGI image directory in configure.pl.
463 Patch submitted by Andreas Vögele.
465 * Applied extensive patch to French translation from Frederic Lehobey.
467 * Minor change to Dutch language $Lang{Pool_Stat} from Wander Winkelhorst.
469 * Minor change to French language $Lang{EMailOutlookBackupMesg} and
470 $Lang{EMailOutlookBackupSubj} from Ludovic Gasc.
472 #------------------------------------------------------------------------
473 # Version 2.1.1, 13 Mar 2005
474 #------------------------------------------------------------------------
476 * Fixed bug in top-level restore using rsync XferMethod.
477 BackupPC::View was leaving an extra leading "/" at the start
478 of top-level directories, messing up the FileList sort order.
479 Reported and debugged by Gail Edwards.
481 * Added pathCreate() to BackupPC_tarExtract so that new directories
482 are created. Required for xtar on MacOSX since the virtual resource
483 fork directories (.rsrc) are not explicitly included in the tar
484 archive - just the files below .rsrc are.
486 * Changed $host.$bkupNum.tar$fileExt.* to $host.$bkupNum.tar$fileExt*
487 in $parCmd in bin/BackupPC_archiveHost.
489 * Fixed HostSortCompare() in BackupPC to correctly sort hosts so
490 those with the oldest backups get queued first.
492 * Changed test in BackupPC_sendEmail so that directories/files
493 starting with "." in $TopDir/pc are ignored, rather than
496 * Changed BackupPC_sendEmail to include NT_STATUS_FILE_LOCK_CONFLICT
497 in check for bad outlook files.
499 * Ensure that %Status and %StatusHost are empty if requesting
500 status on hosts in lib/BackupPC/CGI/Lib.pm GetStatusInfo().
501 Fixes problem with new hosts under mod_perl.
503 * Added images/icon-hardlink.gif so that hardlinks show file type icon.
505 #------------------------------------------------------------------------
506 # Version 2.1.0pl1, 15 Aug 2004
507 #------------------------------------------------------------------------
509 * Added fix to nl.pm from Lieven Bridts.
511 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
512 writes the status and shuts down.
514 * Changed BackupPC_nightly so that it doesn't call find() if the
515 directory doesn't exist. This avoids errors in certain versions
516 of perl. Reported by Bernd Rilling.
518 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
519 Reported by Tony Nelson and Jimmy Liang.
521 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
522 reported by Thomas Tempé.
524 * Added newline to "...skipping because of user requested delay..."
525 log message in BackupPC_dump. Reported by Wayne Scott.
527 * Added read file size error checking to BackupPC_tarCreate.
528 Reported by Brandon Evans.
530 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
531 compression is toggled on/off, a compressed backup doesn't link
532 to an uncompressed pool file (and an uncompressed backup doesn't
533 link to a compressed pool file). Reported by Brandon Evans.
535 * Updated documentation with new dirvish URL and a typo from
538 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
539 for hosts that have failed backups. Reported by Simon Kuhn.
541 #------------------------------------------------------------------------
542 # Version 2.1.0, 20 Jun 2004
543 #------------------------------------------------------------------------
545 * Added Dutch translation from Lieven Bridts, with tweaks from
548 * Added PC-specific config file read in CGI/Archive.pm. Patch
551 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
552 Patch from Pete Wenzel.
554 * Cosmetic changes to PC Summary and Log file language strings from
557 * BackupPC::Lib tries to be more careful when renaming the backups
558 file to backups.old. There have been reports of backups being
559 empty, perhaps when the BackupPC data file system fills up.
560 Now backups is not renamed to backups.old if backups is empty.
562 * BackupPC now closes stderr and stdout before renaming and
563 re-opening the log file.
565 * Pre/post backup/restore/archive commands now correctly set
566 "type" to either incr/full/restore/archive, and now cmdType
567 is the type of Pre/post backup/restore/archive command.
569 * BackupPC_archive correctly terminates archive processes on
572 * Updates to BackupPC_stnd.css with absolute font sizes instead
575 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
576 also ensures the full backup is older than the maximum age
577 expected from $Conf{FullPeriod}.
579 #------------------------------------------------------------------------
580 # Version 2.1.0beta2pl1, 30 May 2004
581 #------------------------------------------------------------------------
583 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
585 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
586 since zip file formats don't support earlier dates. Reported
589 * CGI restore via zip and tar now makes sure stderr is ignored
590 when BackupPC_tarCreate and BackupPC_zipCreate are run.
591 Previously any stderr output would get mixed in the archive,
592 corrupting it. Reported by Dan Niles.
594 #------------------------------------------------------------------------
595 # Version 2.1.0beta2, 23 May 2004
596 #------------------------------------------------------------------------
598 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
599 to every share, rather than just the first, in the case where
600 they are arrays and there are multiple shares. Suggested
603 * On the phase 2 retry pass with rsync, verify the cached checksums
604 if checksum caching is turned on. This will catch the case of
605 cached checksums being incorrectly appended to the compressed
606 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
607 so that cached checksums are verified with a selectable probability.
608 Also, increased File::RsyncP version number to 0.51.
610 * configure.pl now supports an optional batch mode. Command-line
611 options are used to specify all the information that configure.pl
612 needs. This is useful for building auto-install packages.
613 Also, configure.pl now includes pod documentation, so you can do
614 "perldoc configure.pl" to see all the command-line options.
615 Suggested, tested and tweaked by Stuart Herbert for possible
618 * At each wakeup, clients are now queued based on how old the most
619 recent backup is. Clients with errors are queued first, with
620 the oldest error times going first. The rest of the clients are
621 queued next, with the clients with the oldest backup going first.
622 Previously the clients were simply queued in alphabetic order.
623 Suggested by Mike Trisko and Tony Nelson.
625 * Added config parameter $Conf{PartialAgeMax} that controls whether
626 partials are saved at all, and if so, whether the partial will be
627 ignored at the next full backup if it is too old.
629 * BackupPC_tarExtract now allows empty archives without reporting
630 an error. Reported by Don Silvia.
632 * Removed Browse Backups link from Nav Bar in Archive Info display.
633 Reported by Ralph PaĂŸgang.
635 * Fixed documentation display for regular users. Reported by Ralph PaĂŸgang.
637 * Status and PC Summary now work for regular users and only show
638 that user's hosts. Server general status information only appears
639 for admins. Suggested by Ralph PaĂŸgang.
641 * Moved the last three navigation-bar links (docs, FAQ and SF) to
642 a new config parameter $Conf{CgiNavBarLinks}. This allows
643 these links to be locally configured. Based on a patch
644 submitted by Ralph PaĂŸgang.
646 * Allow the navigation bar search box to be disabled by
647 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
648 submitted by Ralph PaĂŸgang.
650 * Updates to de.pm from Ralph PaĂŸgang.
652 * Made the BackupPC icon a link to the SF BackupPC project page.
654 #------------------------------------------------------------------------
655 # Version 2.1.0beta1, 4 Apr 2004
656 #------------------------------------------------------------------------
658 * The CSS definition has been removed from the config.pl file and
659 is now a separate file, BackupPC_stnd.css. A new config variable,
660 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
661 Suggested by Ender Mathias.
663 * Fixed the filling of the host name select box for admins.
664 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
665 Reported by Doug Lytle.
667 * Cleaned up warning message for restore using rsync when checksum
668 caching is on, but when file didn't have cached checksums.
670 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
671 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
673 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
674 giving a significant performance improvement. Patch submitted by
677 * Allow several BackupPC_nightly processes to run in parallel based
678 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
679 traversal of the pool, reducing the overall run time for
682 * Allow BackupPC_nightly to split the pool traversal across several
683 nightly runs. This improves the running time per night, at the expense
684 of a slight increase in disk storage as unused pool files might not
685 be deleted for a couple of days. Controller by new config setting
686 $Conf{BackupPCNightlyPeriod}.
688 #------------------------------------------------------------------------
689 # Version 2.1.0beta0, 20 Mar 2004
690 #------------------------------------------------------------------------
692 * A failed full dump is now saved as a partial (incomplete) dump,
693 provided it includes some files. This can be used for browsing,
694 restoring etc, and will also form the basis of resuming full
695 dumps. Only one partial is kept, and it is removed as soon
696 as a successful full (or a new partial) is done.
698 * Added support for resuming a full dump for rsync. The partial
699 full is kept, and to resume an incremental is done against the
700 partial, and a full is done for the rest.
702 * Added support for Rsync checksum caching. Rsync checksum are
703 appended to the compressed pool files. This means that block
704 and file checksums do not need to be recomputed on the server
705 when using rsync. Requires a patch to rsync to support fixed
706 checksum seeds. This patch is included in the cygwin-rsyncd
707 release on http://backuppc.sourceforge.net.
709 * Major addition of Archive feature from Josh Marshall. Special
710 clients can be configured to be archive targets (eg: tape drives,
711 CD-R). Any subset of the backup clients can be selected and tar
712 archives are created, optionally compressed and split and written
713 to the output device. Logs are maintained and are browsable.
715 * Major changes from Ryan Kucera to add style sheets to the CGI
716 interface, allowing easy customization. Added new icons and
717 BackupPC logo. Numerous navigation improvements.
719 * Added directory history display to BackupPC_Admin, allowing the
720 user to quickly see which files changed between backups on a
723 * Added exponential expiry option for full dumps. This allows you
726 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
727 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
728 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
729 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
730 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
732 and so on. This allows you, for example, to keep 4 weekly fulls,
733 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
734 16 weeks, for roughly 1 year of history. This works by deleting
735 every other full as each expiry boundary is crossed. Suggested
738 * Added Italian language translation it.pm from Lorenzo Cappelletti.
740 * Major updates to language files for new features and tags changes.
741 Updated makeDist to do pedantic consistency checking of language
744 * Addition of administration options from Paul Lukins. Initial
745 page allows server to be started/stopped/reloaded. This still
746 needs some i18n work. Currently the server start/stop is
749 * Split BackupPC_Admin into a set of modules, one for each major action.
750 Each action is now a seperate module in lib/BackupPC/CGI.
752 * Allow the blackout period begin/end to span midnight. Adapted
753 from patch submitted by David Smith.
755 * Allow multiple blackout periods, with new config variable
756 $Conf{BlackoutPeriods} that replaces the old variables
757 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
758 $Conf{BlackoutWeekDays}. Based on patch submitted by
761 * Disabled alarms after forks to avoid timeouts in children that
762 do not reset their alarm. Prompted by ideas from James Leu.
764 * Added options for block size, buffer size and share wild-card to
765 BackupPC_tarCreate. Also added negative backup number options
766 that are relative to the last (so -1 is the last), suggested by
767 William McKee and Carl Soderstrom.
769 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
770 the user is more likely to see the error with BackupPC_tarCreate.
771 Reported by Paul Fox.
773 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
774 case it doesn't already exist.
776 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
777 SI Reasoning and Niranjan Ghate.
779 * Changed restore code so that option #1 (direct restore) can be
780 disabled if the restore command is undefined. Disabling direct
781 restore is necessary if the share is read-only. Suggested by
784 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
785 a decimal point or comma for international versions of Samba.
786 Patch submitted by Frank Gard.
788 * Browsing and directory history now sort the files in a
789 case-insensitive manner.
791 * Changed exec() syntax to allow executing commands whose path
794 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
795 is zero or undefined. The protects the existing backups in the
796 case of a bad config.pl file. Suggested by Christian Warden.
798 * Swapped the Server and Hosts sections on the Nav bar. Moved the
799 host search text box to the top of the hosts section. This was
800 done to move the variable-length part of the Nav bar (when all
801 hosts are displayed) to the bottom.
803 * Fixed a bug in tar restore related to how the common prefix path is
804 removed. Now ensure that the common path is at a directory boundary.
805 Reported by Patrick Neuner.
807 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
808 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
810 * Added Suse notes to init.d/README from Bruno Vernay.
812 * Added Apache 2 documentation fix from Michael Tuzi.
814 #------------------------------------------------------------------------
815 # Version 2.0.2, 6 Oct 2003
816 #------------------------------------------------------------------------
818 * Fixed stupid last-minute change in octal size conversion in
821 #-----------------------------------------------------------------------
822 # Version 2.0.1, 5 Oct 2003
823 #------------------------------------------------------------------------
825 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
826 files in BackupPC_tarCreate.
828 * Removed smbclient size repair in BackupPC_tarExtract for files
829 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
830 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
831 extacted using smbclient 2.2.x. If you have problems backing up
832 files whose size is between 2GB and 4GB using smbclient 2.2.x
833 you should upgrade smbclient to 3.0, since it now generates
836 * Replace PingClientPath with PingPath in configure.pl.
838 * Removed -T (taint mode) on binaries installed in configure.pl.
840 * Added support for smbclient from samba version 3.0.0.
842 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
845 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
846 if it is not defined. This allows the CGI interface to work
847 when AdminUsers = '*'. Reported by Quentin Arce.
849 * For SMB, code that detected files with a read-locked region (eg:
850 outlook .pst files), removed them and then tried to link with an
851 earlier version was broken. This code missed a step of mangling
852 the file names. This is now fixed. Reported by Pierre Bourgin.
854 * A backup of a share that has zero files is now considered
855 fatal. This is used to catch miscellaneous Xfer errors that
856 result in no files being backed up. A new config parameter
857 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
858 zero to turn off this check. Suggested by Guillaume Filion.
859 Additional change: this check only applies to a full dump.
861 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
862 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
863 smbclient.) Suggested by Guillaume Filion.
865 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
866 the dump is considered failed.
868 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
869 which just included the '/' directory and nothing below. Now it
870 does just --include '/', which should include everything.
873 * Add hostError to DumpPostUserCmd variable substitutions for both dump
876 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
877 makes BackupPC_dump -v work better.
879 * Don't allow browsing with ".." in directory in case a user tries
880 to trick BackupPC_Admin into displaying directories outside where
883 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
884 fixes large file (>2GB) bugs. Large file bugs reported by Steve
887 #------------------------------------------------------------------------
888 # Version 2.0.0, 14 Jun 2003
889 #------------------------------------------------------------------------
891 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
892 Added "no utf8" to all programs, and added binmode() to relevant
895 #------------------------------------------------------------------------
896 # Version 2.0.0beta3, 1 Jun 2003
897 #------------------------------------------------------------------------
899 * Several improvements to restore: cancel now reports the correct
900 message and cleans up correctly.
902 * Rsync with whitespace and wildcard excludes fixed by replacing
903 argList with argList+ in config.pl plus a fix to Lib.pm for
904 shell escaping array arguments.
906 * Fixed rsync restore for character and block special devices
907 (major and minor device numbers weren't correctly restored).
909 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
911 * (Re)-fixed "Bad command" in log file when restore via tar or zip
912 file download is done.
914 * Added untaint to exec in Lib.pm to avoid tainted errors.
916 * Applied additional tweak to hilight patch from Tim Demarest.
918 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
921 * Don't display RsyncdPasswd when displaying config.pl files.
923 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
924 which increases typical buffering from 4K to 16K-64K. This improves the
927 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
928 then a warning is printed.
930 #------------------------------------------------------------------------
931 # Version 2.0.0beta2, 11 May 2003
932 #------------------------------------------------------------------------
934 * Added German translation, provided by Manfred Herrmann.
936 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
938 * Fixed zip and tar file download from CGI under mod_perl. Reported
939 by Pierre Bourgin and Paul Lukins.
941 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
942 Reported by several users.
944 * Added -v option to BackupPC_dump for verbose output (useful when
945 you run the command manually). Added messages for all exits.
947 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
948 now returns the first IP address that matches the subnet mask.
949 Suggested by Tim Demarest.
951 * Fixed BackupPC::View so the top-level directory is handled correctly.
952 This allows the top-level share/directory to be restored via the
953 CGI interface. Reported by several users.
955 * Fixed RsyncFileIO failures on certain large files by replacing seek()
956 with sysseek(). Reported by Manfred Herrmann.
958 * Added configurable highlighting of PC status in the CGI summary
959 screen; submitted by Tim Demarest.
961 * Fixed command queue CGI display; submitted by Tim Demarest.
963 * BackupPC_trashClean now logs an error if it can't remove all the
964 trash and then goes back to sleep, rather than continually trying.
966 * Moved correct user (uid) check into BackupPC::Lib so that all
967 applications do a user check if $Cong{BackupPCUserVerify} is
968 set. The avoids the risk of manually running BackupPC_dump as
971 * Loss of blackout now applies to "host not found" as well as no ping.
972 Reported by Dale Renton.
974 * "Host not found" is now treated in a similar manner to "no ping".
976 * Added suse-linux init.d script from Leon Letto.
978 * Added Gentoo linux init.d script from Tim Demarest.
980 * Applied additional i18n strings from GFK and the translation team.
982 * Fixed option parsing so that getopts errors are reported and we exit.
984 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
986 #------------------------------------------------------------------------
987 # Version 2.0.0beta1, 30 Mar 2003
988 #------------------------------------------------------------------------
990 * Added Spanish translation es.pm from Javier Gonzalez.
992 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
993 when directories were selected in a certain order.
995 * Fixed BackupPC::PoolWrite so that it can recover when the initial
996 file size is wrong. This is needed since rsync could write a file
997 whose size is different from the initial size returned in the
998 file list when that file is updated while rsync is running.
1000 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
1001 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
1002 helps, but it should be benign. See:
1003 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
1005 #------------------------------------------------------------------------
1006 # Version 2.0.0beta0, 23 Feb 2003
1007 #------------------------------------------------------------------------
1009 * Support for rsync and rsyncd backup and restore. Changes to
1010 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
1011 and BackupPC::Xfer::RsyncFileIO.
1013 * Added internationalization (i18n) code from Xavier Nicollet,
1014 with additions from Guillaume Filion. Voila! BackupPC_Admin
1015 now supports English and French, and adding more languages is
1016 now easy. New config paramater $Conf{Language} sets the language.
1018 * Added optional user-defined pre/post dump/restore commands, allowing
1019 things like database shutdown/startup for dumps.
1021 * Changed the way hosts are found.
1023 * Added $Conf{ClientNameAlias}, which allows the name of the physical
1024 client machine to be set. This allows several different backup
1025 "hosts" to all refer to the same physical machine, which is
1026 convenient if several different types of data need to be backed
1027 up, or if different parameters are needed for different parts of
1030 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
1031 $Conf{NmbLookupCmd} allowing all these commands to be fully
1032 configured. Also, all commands can also now be fragments of
1035 * Moved all smbclient commands into the config.pl file so the specific
1036 arguments can be customized. New config parameters are
1037 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
1038 $Conf{SmbClientRestoreCmd}.
1040 * Added new BackupPC::View module that creates views of backups
1041 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
1042 and BackupPC_tarCreate to use BackupPC::View. This removes lots
1043 of merging and mangling code from the higher-level code.
1045 * Added code from Toby Johnson that allows additional users to be
1046 specified in the hosts file; these users can also view/start/stop
1047 and restore backups for that host. Also added a new config
1048 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
1049 be listed in the left nav bar for admins.
1051 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
1052 the maximum number of hardlinks per file in the pool. If a file
1053 ever gets to this number of links a new pool file is created to
1054 handle additional links.
1056 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
1057 modules to be loaded.
1059 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
1060 allow language-specific default messages to be overridden.
1062 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
1063 files to be represented in the attrib file correctly.
1065 * Added support for environment variable BPC_SMB_PASSWD, which is the
1066 client's smb password. This overrides the old environment variable
1069 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
1071 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
1072 handle files with trailing spaces.
1074 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
1075 to ignore multiple signals of the same type.
1077 * Added reporting of the largest number of hardlinks in the pool to the
1080 * Adding reporting of syntax errors in the per-PC config.pl file.
1082 * Updated BackupPC_sendEmail to handle language-specific email messages.
1084 * Allow client (host) names to contain spaces. Spaces in host names
1085 need to be escaped via "\" in the hosts file. The user of spaces in
1086 host names is discouraged, but they should work. One feature that
1087 doesn't work with host names that contain spaces is the highlighting
1088 of that name in the log file display in the CGI interface. There are
1089 no plans to fix this.
1091 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
1093 * Fixed all open() calls to use 3 argument form to fix handling of file
1094 names with trailing whitespace. Also fixed CGI interface so these
1095 file names are displayed correctly.
1097 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
1098 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
1099 Reported by Pascal Schelcher. Fixed similar problem reported by
1102 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
1103 suggested by Tim Demarest.
1105 #------------------------------------------------------------------------
1106 # Version 1.5.0, 2 Aug 2002
1107 #------------------------------------------------------------------------
1109 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
1110 option instead of --newer-mtime. Also removed --atime-preserve from
1111 $Conf{TarClientCmd}. This makes the default settings work better
1114 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
1115 so it can correctly warn the user to stop it before upgrading. Reported
1118 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
1119 Reported by Guillaume Filion.
1121 * Added LDAP setup to documentation from David Holland.
1123 * Tar.pm now adds a "." to file paths that start with "/", so that all
1124 tar paths are relative. From Ludovic Drolez.
1126 #------------------------------------------------------------------------
1127 # Version 1.5.0beta0, 30 Jun 2002
1128 #------------------------------------------------------------------------
1130 * A full set of restore options is now supported, including direct
1131 restore via smbclient or tar or downloading a zip or tar file.
1133 * Major additions to CGI script to support better directory navigation,
1134 restore features and mod_perl. Also, file downloads from the CGI
1135 interface now correctly preserve the file name and provide the
1136 correct Content-Type for the most common types of files. Improved
1137 directory navigation was contributed by Ryan Kucera.
1139 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
1140 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
1141 create a zip archive of any portion of a backup.
1143 * Substantial additions to BackupPC_tarCreate to support restore,
1144 including modifying path names, handling hardlinks, fixing
1145 support of old backups without attributes (pre-v1.4.0). Plus
1146 BackupPC_tarCreate is now an offical part of the release.
1147 (Lack of support for hardlinks was reported by John Stanley.)
1149 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
1152 * A unix domain socket is now used for communication between the CGI
1153 interface and BackupPC. The original TCP socket is optional. Sockets
1154 are correctly re-initialized if config.pl is updated with new socket
1157 * For improved security messages over the unix or TCP socket are protected
1158 via an MD5 digest based on a shared secret, a sequence number, a time
1159 stamp and a unique per-connection number.
1161 * Additions to configure.pl to support install of directory navigation
1164 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
1165 were set to a single string or list (in v1.4.0 only the case of
1166 hash worked correctly). Reported by Phillip Bertolus.
1168 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
1169 client always subject to blackout, matching the comments in config.pl.
1170 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
1171 reported by Pascal Schelcher.
1173 * Fixed byte and file totals for tar backups, reported by several users.
1175 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
1176 suggested by Erminio Baranzini.
1178 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
1179 well as shell escaping of tar arguments.
1181 * Fixed entity encoding of 8-bit characters in the CGI interface.
1183 * Added optional CGI headers in $Conf{CgiHeaders} that by default
1184 is set to a no-cache pragma. Suggested by Benno Zuure.
1186 #------------------------------------------------------------------------
1187 # Version 1.4.0, 16 Mar 2002
1188 #------------------------------------------------------------------------
1190 * BackupPC now supports tar (in addition to smb) for extracting host
1191 data. This is the most convenient option for linux/unix hosts.
1192 Tar can be configured to run over ssh, rsh or to backup a local
1193 nfs mount from the host.
1195 * Support for special files, including symbolic links, fifo, character
1196 and block device files has been added, so that all native linux/unix
1197 file types can be correctly backed up when using tar transport.
1198 Special files are all stored as regular files and the type attributes
1199 are used to remember the original file type.
1201 * All unix file attributes are now saved (and pooled when possible).
1202 This includes user and group ownership, permissions, and modification
1203 time. Smbclient also does a reasonable job of emulating unix
1204 permissions (such as mtime), and these attributes get saved too.
1206 * The new default is to not fill incremental dumps. configure.pl
1207 automatically sets $Conf{IncrFill} to 0. The default was 1
1208 (incrementals were filled with hardlinks). Since the CGI
1209 script does filling at browsing time, there is no need to
1210 fill incremental dumps.
1212 * Backup file names are now stored in "mangled" form. Each node of a
1213 path is preceded by "f", and special characters (\n, \r, % and /) are
1214 URI-encoded as "%xx", where xx is the ascii character's hex value. So
1215 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
1216 was done mainly so meta-data could be stored alongside the backup
1217 files without name collisions. In particular, the attributes for the
1218 files in a directory are stored in a file called "attrib", and
1219 mangling avoids file name collisions (I discarded the idea of having
1220 a duplicate directory tree for every backup just to store the
1221 attributes). Other meta-data (eg: rsync checksums) could be stored in
1222 file names preceded by, eg, "c". There are two other benefits to
1223 mangling: the share name might contain "/" (eg: "/home/craig" for tar
1224 transport), and I wanted that represented as a single level in the
1225 storage tree. Secondly, as files are written to NewFileList for later
1226 processing by BackupPC_link, embedded newlines in the file's path
1227 will cause problems which are avoided by mangling.
1229 The CGI script undoes the mangling, so it is invisibe to the user.
1230 Of course, old (unmangled) backups are still supported by the CGI
1233 * Various changes to the CGI interface, BackupPC_Admin:
1235 + Added button that allows users to manually start a full dump in
1236 addition to the existing incremental dump.
1238 + Added display of file attributes when browsing backups.
1240 + Added an optional holdoff time specified by the user when canceling
1241 a backup. BackupPC will not attempt any new backups for at least the
1242 specified time. This holdoff time can be changed whether or not a
1245 + Added supports for file mangling, and correct merging of unfilled
1246 backups from mangled or unmangled (and compressed or uncompressed)
1247 fulls when browsing or restoring.
1249 + Only displays a "Start Incr Backup" button if there are already some
1252 + For DHCP hosts, when a user tries to manually start a backup, add
1253 a check for the netbios name of both the host the request came
1254 from (REMOTE_ADDR) and the last known DHCP address for that host
1255 to see if either address matches the host. If not, an error
1256 message is display. The previous behavior was that only requests
1257 from the client itself succeeded, and requests from other machines
1260 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
1261 is 1.4.0. The first digit is for major new releases, the middle digit
1262 is for significant feature releases and improvements, and the last
1263 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
1264 and 1.03 as 1.0.0, ..., 1.3.0.
1266 * BackupPC and the CGI script BackupPC_Admin now check that the effective
1267 user id is correct to avoid accidentally launching BackupPC as the
1268 wrong user or detecting CGI configuration problems. This behavior
1269 can be turned off using the $Conf{BackupPCUserVerify} option.
1271 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
1272 support generic names for both smb and tar transport methods. The
1273 CGI script checks for old names for backward compatibility.
1275 * Major changed to Backup_dump to support new tar transport. All transport
1276 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
1279 * Added workaround for a bug in Samba's smbclient for files between 2GB
1280 and 4GB. The file size in the tar header is incorrect. This allows
1281 files up to 4GB to work with smbclient, rather than 2GB. To support
1282 files larger than 2GB you must make sure perl is compiled with the
1283 uselargefiles option (use "perl -V | egrep largefiles" to check) and
1284 the pool directory must be on a file system that supports large files.
1286 * Moved the pool writing code into a module BackupPC::PoolWrite. This
1287 allows the clever file pool checking (digest, uncompressing, comparing
1288 etc with minimum disk IO) to be used easily in multiple places (eg: it
1289 is now used for writing attribute files so they can be pooled).
1291 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
1293 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
1294 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
1295 on one user's machine was world writable and perl -T correctly
1296 complained about it.
1298 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
1299 Thanks to Kyle Amon for sending the fix. Decided to move the
1300 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
1301 now configure.pl tries to come up with a sensible default based on
1304 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
1305 share name (eg: C$). Thanks to Jules Agee for this fix. Also
1306 changed the default config.pl so that single quotes are used
1307 everywhere so that people don't get tripped up putting '$' inside
1308 double-quoted strings.
1310 #------------------------------------------------------------------------
1311 # Version 1.03, 9 Dec 2001
1312 #------------------------------------------------------------------------
1314 * BackupPC now has full support for compression. There are now two
1315 pool areas, the original pool for uncompressed files, and cpool for
1316 compressed files. The compression is done by Compress::Zlib.
1317 Compression reduces the pool disk usage by around 40%, although your
1318 mileage may vary. Compression is optional and can also be specified on
1319 a per-PC basis (although this will cost more pool storage since many
1320 backup files will have to be stored in both compressed and
1323 * A new script, BackupPC_compressPool, can be run to compress the entire
1324 pool. This is used once to migrate all the pool data from uncompressed
1325 to compressed on existing installations. Read the documentation
1326 (Installing BackupPC/Compressing an existing pool) before running
1327 BackupPC_compressPool!
1329 Alternatively, compression can simply be turned on and all new backups
1330 will be compressed. Both old (uncompressed) and new (compressed)
1331 backups can be browsed and viewed. Eventually, the old backups will
1332 expire and all the pool data will be compressed. However, until the
1333 old backups expire, this approach could require 60% or more additional
1334 pool storage space to store both uncompressed and compressed versions
1335 of the backup files.
1337 * Significant improvements to the cgi interface, BackupPC_Admin:
1339 - much better layout navigation
1340 - handles compressed backup files and compressed log files
1341 - handles unfilled incremental dumps
1342 - better backup directory browsing navigation
1343 - reports compression statistics
1344 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
1345 - Additional customization with $Conf{CgiHeaderFontType},
1346 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
1347 $Conf{CgiHeaderBgColor}.
1349 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
1350 file and queues the PCs itself. Like config.pl, BackupPC will
1351 re-read the hosts file on each wakeup if its modification time
1352 changes, or upon a SIGHUP. This also makes for better behavior
1353 when adding a host: if you add hosts, simply send a SIGHUP to
1354 BackupPC or wait for the next wakeup.
1356 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
1358 * BackupPC_dump keeps track of compressed file sizes so that compression
1359 statistics can be reported by the cgi interface.
1361 * Aging of old log files now handles compressed log files (.z extension).
1363 * Added configuration option $Conf{IncrFill} to specify whether
1364 incremental dumps should be filled in. Old behavior was that
1365 filling was on. Now it's optional. See config.pl for more
1368 * BackupPC_nightly now cleans and generates statistics for both
1369 the uncompressed pool and compressed pool (cpool).
1371 * Added new utility script BackupPC_zcat that can be used to
1372 uncompresses BackupPC files.
1374 * configure.pl offers various options related to compression,
1375 depending upon whether this is a new install or upgrade,
1376 and whether or not Compress::Zlib is installed.
1378 * configure.pl now makes a backup copy of config.pl before
1379 config.pl is updated.
1381 * added three new fields to the backups file to handle optional
1382 filling and compression stats.
1384 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
1385 on each dhcp host once each night to verify that very old backups are
1386 expired. This ensures that very old backups are expired even if
1387 the dhcp host has not been on the network for a long time.
1389 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
1390 even if compression was off. Thanks to Steve Holmes for reporting
1393 * fixed bug that caused a BackupPC queue to get blocked when a backup
1394 cancel attempt was made during the BackupPC_link phase.
1396 #------------------------------------------------------------------------
1397 # Version 1.02, 28 Oct 2001.
1398 #------------------------------------------------------------------------
1400 * Added new script BackupPC_tarExtract to extract the smbclient tar
1401 archive. This reduces disk writes by perhaps 90-95% and disk reads by
1402 50%. Previously, tar was used to extract and write everything to disk.
1403 Then BackupPC_dump would read enough of each file to compute the MD5
1404 digest, and then compare the full file with candidate pool files. So
1405 for each 1MB file that matches a single file in the pool, there would
1406 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
1408 BackupPC_tarExtract instead extracts the archive using a 1MB memory
1409 buffer. This allows the MD5 digest to be computed without touching the
1410 disk. Next, any potential pool file compares are done by comparing the
1411 pool file against the incoming tar data in memory, which only requires
1412 the pool file to be read. So for each 1MB file that matches a single
1413 file in the pool, there are now no disk writes, and only 1MB of reads.
1414 BackupPC_tarExtract handles arbitrary size files and repeated
1415 potential pool matches. If the incoming file doesn't match the pool
1416 then it is written to disk (once the pool is mature this happens maybe
1419 * Substantial changes to BackupPC_dump:
1421 + BackupPC_tarExtract is now used in place of tar.
1423 + BackupPC_dump now reads the output from both smbclient and
1424 BackupPC_tarExtract and merges them into SmbLOG.
1426 + Named pipes are no longer used to connect smbclient to tar
1427 (now BackupPC_tarExtract). Regular pipes are used instead.
1428 This avoids the need to system mknod or mkfifo.
1430 + Locked files on the client that can't be read by smbclient
1431 previously were filled with 0x0 bytes by smbclient, meaning
1432 tar extracted a useless file filled with 0x0 bytes. Now,
1433 BackupPC_dump watches the output of smbclient and removes
1434 any files that smbclient couldn't read. This avoids storing
1435 useless files. It tries to replace such files with a hard link
1436 to a previous dump. These actions appear in the log file.
1438 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
1439 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
1440 reading and writing compressed and regular files and provides all the
1441 hooks for compression support in BackupPC (should be supported in next
1442 version). BackupPC::FileIO also does efficient writing of files that
1443 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
1444 helpful when smbclient reads a locked file, and it fills the tar
1445 output with a file of the correct size but all 0x0. Such files will be
1446 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
1447 writes such files efficiently (as sparse files), meaning just a few
1448 blocks of disk space will be needed even if the file is large.
1450 * alive/dead counting for blackout now works correctly for DHCP hosts.
1452 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
1453 killed and restarted with backups running.
1455 * added extra non blocking select() in BackupPC to make sure the socket
1458 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1460 * Updated BackupPC_sendEmail to correctly parse the locked file
1461 error from 2.2.1a smbclient, so that missing Outlook file emails
1462 can be correctly sent.
1464 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1465 hostname read from the hosts file.
1467 * BackupPC_Admin provides general summary when the host name is empty.
1469 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1471 * configure.pl complains if BackupPC is already running, reminding you
1472 to stop it before upgrading.
1474 * updated documentation, and fixed auto-insertion of config.pl into
1475 BackupPC.pod (previously the last config parameter was left out of

1482 * Documentation cleanup in README, doc/BackupPC.pod, conf/config.pl.
1484 * BackupPC_sendMail now reads the optional per-PC config file, allowing
1485 email configuration parameters to be set on a per-PC basis.
1487 * Removed the unused 4096-length MD5 digest code in lib/BackupPC/Lib.pm.
