21 # Version __VERSION__, __RELEASEDATE__
22 #------------------------------------------------------------------------
24 * Fix for config.pl writing code to handle multi-line expressions.
25 Reported by David Relson and others.
27 * Fix for CGI editor when deleting hash entries whose keys are
28 non alphanumeric. Report by David Relson.
30 #------------------------------------------------------------------------
31 # Version 3.0.0beta2, 18 Nov 2006
32 #------------------------------------------------------------------------
34 * Fix for final md4 digest check on rsync transfers >= 512MB when protocol
35 version >= 27 and checksums are not cached. Reported by Garith Dugmore
38 * Config Editor "Save" button is now always visible, but greyed out
39 until there are changes to save.
41 * Config editor allows other tabs to be selected when there is an
42 error, which allows you to fix an error (eg: missing binary) in
43 an exiting config file. Errors are now displayed at the top of
44 the page in addition to next to the erroneous setting.
46 * configure.pl checks version of Encode.pm. Reported by Chris Stone.
48 * Several fixes to bin/BackupPC_fixupBackupSummary from Stian Jordet.
50 * Fixed config.pl editor writing to solve bug with multi-line text
51 strings ending in newline. Reported and root caused by Les Stott
54 * Fixed error recovery case in BackupPC::PoolWrite, reported by
57 * Fixed table width in backup browsing to avoid Firefox layout anomoly,
58 provided by Jono Woodhouse.
60 * CSS file updates from Jono Woodhouse. Prior (v2) version is included
61 as BackupPC_stnd_orig.css in case people prefer the old skin.
63 * More compact host summary, including disabled host indication,
66 * New directory/file/hardlink and symlink image icons from Sean Cameron
67 and Jono Woodhouse, making directory browse more compact.
69 * BackupPC.pid is now world readable, suggested by Casper Thomsen.
71 * Reordered the Server navigation bar links, suggested by David Relson.
73 * Fixed typos in init.d/src/gentoo-backuppc, configure.pl and config.pl
74 reported by David Relson.
76 #------------------------------------------------------------------------
77 # Version 3.0.0beta1, 30 Jul 2006
78 #------------------------------------------------------------------------
80 * Fixed several Xfer charset conversions.
82 * Added some CGI utf8 conversions from Rodrigo Real and Vincent
85 * Rsync transfers now correctly handle file names with \n or \r.
87 * Host name is forced to lower case, to match 2.x.
89 * Fixed LOG file naming in BackupPC_restore and BackupPC_archive.
91 * GFK applied fr.pm corrections from Nicolas Stransky.
93 * Updated init.d/src scripts for FHS (ie: replaced __TOPDIR__/log
94 with __LOGDIR__ and __TOPDIR__/conf with __CONFDIR__). Patch
95 provided by Rodrigo Real.
97 * Added --log-dir and --conf-dir options to configure.pl.
98 Reported by Vincent Fleuranceau.
100 * Updated File::RsyncP version check in configure.pl, reported
101 by Vincent Fleuranceau. Changed File::RsyncP version to 0.64.
103 #------------------------------------------------------------------------
104 # Version 3.0.0beta0, 11 Jul 2006
105 #------------------------------------------------------------------------
107 * Added configuration and host CGI editor.
109 * Added rsync hardlink support. Requires latest version of
112 * Decoupled BackupPC_dump from BackupPC_nightly by making
113 asynchronous file linking/delete robust to race conditions.
114 Now only BackupPC_nightly and BackupPC_link are mutually
115 exclusive so only one runs at a time, and BackupPC_dump and
116 BackupPC_restore can run anytime.
118 * Added support for multi-level incrementals. In the style of dump(1),
119 the level of each incremental can be specified. Each incremental
120 backups up everything since the most recent backup of a lower level
121 (fulls are always level 0). Previous behavior was all incrementals
122 were level 1, meaning they backed up everything since the last full
123 (level 0). Default configuration is all incrementals are level 1.
125 * Server file names are now in utf8 and optional conversion
126 to/from client name charsets can be configured. All CGI pages
127 now use the utf8 charset.
129 * Backup metadata is now additionally saved to pc/HOST/nnn/backupInfo,
130 in addition to pc/HOST/backups. In case pc/HOST/backups gets trashed,
131 then a new script BackupPC_fixupBackupSummary can read the per-backup
132 metadata from pc/HOST/nnn/backupInfo and reconstruct the backups file.
133 Roberto Moreno also pointed out an early error in the CVS version.
135 * Added Storage module and Storage::Text which localizes all the
136 text data file reading/writing (eg: backups, restores, archives
137 and config.pl files). Added read verify after all write
138 operations for robustness. Additional backends (eg: SQL)
139 can be added in the future as new subclasses of the Storage
142 * Added Config module, and Config::Meta that contains meta data
143 about configuration parameters.
145 * Added RSS support from Rich Duzenbury.
147 * Translations of new 3.0 language strings from Guillaume Filion,
148 Reginaldo Ferreira, Ralph Passgang, Lieven Bridts, Guus Houtzager,
151 * Added optional checking of exit status of Dump/Restore/Archive Pre/Post
152 UserCmd, requested by Kiko Jover, Matthias Bertschy and others.
154 * For new installations configure.pl tries to comply with the file
155 system hierarchy standard, which means all the configuration files
156 below /etc/BackupPC and log files go below /var/log/BackupPC.
158 * Added Slackware init.d script from Tony Nelson.
160 * Fixed error reporting when restore/archive fail to write the
161 request file to the client directory.
163 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
165 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
166 to DumpPreUserCmd etc.
168 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
170 * Jean-Michel Beuken reported several bugs in configure.pl in CVS 3.0.0.
172 * Old backup email warnings now ignore partials requested by Samuel Bancal
174 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
175 ignores any file starting with "." in the pc directory when
176 it is generating warnings about old/unused files/directories.
178 * Applied patch from Marc Prewitt to fix host queue order.
180 * Applied Lorenzo Cappelletti's it.pm patch.
182 * Applied Wander Winkelhorst's nl.pm patch.
184 * Applied Alberto Marconi's it.pm patch.
186 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
187 BackupPC_sendEmail to fix bug reported by Dale Renton.
189 * Added fixup of $ENV{REMOTE_USER} to lib/BackupPC/CGI/Lib.pm in the
190 case of using mod_authz_ldap; patch submitted by Alain Perrier.
192 * Added env LC_ALL=C to $Conf{TarClientCmd} and $Conf{TarClientRestoreCmd}
193 to avoid locale problems, suggested by Ludovic Drolez.
195 * Changed ping output parsing to pick out average rtt time, based
196 on patch from Ron Bickers.
198 * Removed leading "./" and top-level "./" directory from
199 zip archives generated by BackupPC_zipCreate. Reported
200 by Josh (hecktarzuli).
202 * BackupPC_tarCreate and BackupPC_zipCreate now allow "@"
203 in share names. Reported by Robert Waldner.
205 * NT_STATUS_INSUFF_SERVER_RESOURCES is now a fatal error for
206 smbclient transfers, suggested by Brian Shand.
208 * Changed bin/BackupPC_archiveHost to use /bin/csh instead of
209 /bin/sh. That way any errors in the pipeline are reported
210 via the exit status, instead of just the last.
212 * Added $Conf{EMailHeaders} for additional email headers, requested
213 by Ludovic Gasc. If the Content-Type charset is set to utf8 then
214 the body of the email is sent in utf8 coding.
216 * Made shareName argument regexp checking more general to allow parens.
218 * Added some debian init.d instructions to init.d/README from
221 * Documentation updates from Richard Ames, JP Vossen, Torsten Finke.
223 #------------------------------------------------------------------------
224 # Version 2.1.2pl2, 18 Jun 2006
225 #------------------------------------------------------------------------
227 * In conf/config.pl, changed --devices to -D in $Conf{RsyncArgs}
228 and $Conf{RsyncRestoreArgs} to fix "fileListReceive failed" and
229 "Can't open .../f%2f for empty output" errors with rsync 2.6.7+.
230 Fix proposed by Justin Pessa and Vincent Ho, and confirmed by
233 * Added patch from Michael (mna.news) to ignore "file is unchanged"
234 message from tar 1.15.x during incremental backups.
236 * Fixed creation of .rsrc directories in bin/BackupPC_tarExtract
237 when used with xtar on MacOS. Reported by Samuel Bancal and
238 Matthew Radey, who helped with debugging.
240 * Fixed bug in BackupPC_tarExtract for files >8GB in size whose
241 lengths are multiples of 256. Reported by Jamie Myers and
242 Marko Tukiainen, who both helped debugging the problem.
244 * Fixed bug in lib/BackupPC/Xfer/RsyncFileIO.pm that caused
245 incorrected deleted attributes to be set in directories
246 where one of the files had an rsync phase 1 retry during
247 an incremental. Reported by Tony Nelson.
249 #------------------------------------------------------------------------
250 # Version 2.1.2, 5 Sep 2005
251 #------------------------------------------------------------------------
253 * Fixed simple but serious bug in bin/BackupPC_tarCreate that prevented
254 hardlinks being saved correctly. Debugged by Michael (mna.news)
255 with several other people.
257 * Fixed serious bug in bin/BackupPC_dump reported/debugged by Dan Niles
258 that can happen when multiple full backups are deleted after
259 $Conf{FullKeepCnt} is changed.
261 * Changed lib/BackupPC/CGI/Lib.pm so that link to "$TopDir/conf/$host.pl"
262 is displayed if it exists. Patch from Andreas Vögele.
264 * Applied daemonize patch to bin/BackupPC from:
265 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=301057
267 * It's now a fatal error if $Conf{CompressLevel} is set, but
268 Compress::Zlib is not found. Before $Conf{CompressLevel} was
269 silently set to 0, which made all the backups uncompressed.
270 That meant the user never knew if they forget to install
271 Compress::Zlib but were expecting compression to be on.
273 * Finally increased $Conf{ClientTimeout} to 72000 (20 hours).
275 * Added sleep 1 in restart() function in init.d/src/gentoo-backuppc,
276 suggested by Jon Hood.
278 * Added $DestDir to the path of the CGI image directory in configure.pl.
279 Patch submitted by Andreas Vögele.
281 * Applied extensive patch to French translation from Frederic Lehobey.
283 * Minor change to Dutch language $Lang{Pool_Stat} from Wander Winkelhorst.
285 * Minor change to French language $Lang{EMailOutlookBackupMesg} and
286 $Lang{EMailOutlookBackupSubj} from Ludovic Gasc.
288 #------------------------------------------------------------------------
289 # Version 2.1.1, 13 Mar 2005
290 #------------------------------------------------------------------------
292 * Fixed bug in top-level restore using rsync XferMethod.
293 BackupPC::View was leaving an extra leading "/" at the start
294 of top-level directories, messing up the FileList sort order.
295 Reported and debugged by Gail Edwards.
297 * Added pathCreate() to BackupPC_tarExtract so that new directories
298 are created. Required for xtar on MacOSX since the virtual resource
299 fork directories (.rsrc) are not explicitly included in the tar
300 archive - just the files below .rsrc are.
302 * Changed $host.$bkupNum.tar$fileExt.* to $host.$bkupNum.tar$fileExt*
303 in $parCmd in bin/BackupPC_archiveHost.
305 * Fixed HostSortCompare() in BackupPC to correctly sort hosts so
306 those with the oldest backups get queued first.
308 * Changed test in BackupPC_sendEmail so that directories/files
309 starting with "." in $TopDir/pc are ignored, rather than
312 * Changed BackupPC_sendEmail to include NT_STATUS_FILE_LOCK_CONFLICT
313 in check for bad outlook files.
315 * Ensure that %Status and %StatusHost are empty if requesting
316 status on hosts in lib/BackupPC/CGI/Lib.pm GetStatusInfo().
317 Fixes problem with new hosts under mod_perl.
319 * Added images/icon-hardlink.gif so that hardlinks show file type icon.
321 #------------------------------------------------------------------------
322 # Version 2.1.0pl1, 15 Aug 2004
323 #------------------------------------------------------------------------
325 * Added fix to nl.pm from Lieven Bridts.
327 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
328 writes the status and shuts down.
330 * Changed BackupPC_nightly so that it doesn't call find() if the
331 directory doesn't exist. This avoids errors in certain versions
332 of perl. Reported by Bernd Rilling.
334 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
335 Reported by Tony Nelson and Jimmy Liang.
337 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
338 reported by Thomas Tempé.
340 * Added newline to "...skipping because of user requested delay..."
341 log message in BackupPC_dump. Reported by Wayne Scott.
343 * Added read file size error checking to BackupPC_tarCreate.
344 Reported by Brandon Evans.
346 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
347 compression is toggled on/off, a compressed backup doesn't link
348 to an uncompressed pool file (and an uncompressed backup doesn't
349 link to a compressed pool file). Reported by Brandon Evans.
351 * Updated documentation with new dirvish URL and a typo from
354 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
355 for hosts that have failed backups. Reported by Simon Kuhn.
357 #------------------------------------------------------------------------
358 # Version 2.1.0, 20 Jun 2004
359 #------------------------------------------------------------------------
361 * Added Dutch translation from Lieven Bridts, with tweaks from
364 * Added PC-specific config file read in CGI/Archive.pm. Patch
367 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
368 Patch from Pete Wenzel.
370 * Cosmetic changes to PC Summary and Log file language strings from
373 * BackupPC::Lib tries to be more careful when renaming the backups
374 file to backups.old. There have been reports of backups being
375 empty, perhaps when the BackupPC data file system fills up.
376 Now backups is not renamed to backups.old if backups is empty.
378 * BackupPC now closes stderr and stdout before renaming and
379 re-opening the log file.
381 * Pre/post backup/restore/archive commands now correctly set
382 "type" to either incr/full/restore/archive, and now cmdType
383 is the type of Pre/post backup/restore/archive command.
385 * BackupPC_archive correctly terminates archive processes on
388 * Updates to BackupPC_stnd.css with absolute font sizes instead
391 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
392 also ensures the full backup is older than the maximum age
393 expected from $Conf{FullPeriod}.
395 #------------------------------------------------------------------------
396 # Version 2.1.0beta2pl1, 30 May 2004
397 #------------------------------------------------------------------------
399 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
401 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
402 since zip file formats don't support earlier dates. Reported
405 * CGI restore via zip and tar now makes sure stderr is ignored
406 when BackupPC_tarCreate and BackupPC_zipCreate are run.
407 Previously any stderr output would get mixed in the archive,
408 corrupting it. Reported by Dan Niles.
410 #------------------------------------------------------------------------
411 # Version 2.1.0beta2, 23 May 2004
412 #------------------------------------------------------------------------
414 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
415 to every share, rather than just the first, in the case where
416 they are arrays and there are multiple shares. Suggested
419 * On the phase 2 retry pass with rsync, verify the cached checksums
420 if checksum caching is turned on. This will catch the case of
421 cached checksums being incorrectly appended to the compressed
422 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
423 so that cached checksums are verified with a selectable probability.
424 Also, increased File::RsyncP version number to 0.51.
426 * configure.pl now supports an optional batch mode. Command-line
427 options are used to specify all the information that configure.pl
428 needs. This is useful for building auto-install packages.
429 Also, configure.pl now includes pod documentation, so you can do
430 "perldoc configure.pl" to see all the command-line options.
431 Suggested, tested and tweaked by Stuart Herbert for possible
434 * At each wakeup, clients are now queued based on how old the most
435 recent backup is. Clients with errors are queued first, with
436 the oldest error times going first. The rest of the clients are
437 queued next, with the clients with the oldest backup going first.
438 Previously the clients were simply queued in alphabetic order.
439 Suggested by Mike Trisko and Tony Nelson.
441 * Added config parameter $Conf{PartialAgeMax} that controls whether
442 partials are saved at all, and if so, whether the partial will be
443 ignored at the next full backup if it is too old.
445 * BackupPC_tarExtract now allows empty archives without reporting
446 an error. Reported by Don Silvia.
448 * Removed Browse Backups link from Nav Bar in Archive Info display.
449 Reported by Ralph Paßgang.
451 * Fixed documentation display for regular users. Reported by Ralph Paßgang.
453 * Status and PC Summary now work for regular users and only show
454 that user's hosts. Server general status information only appears
455 for admins. Suggested by Ralph Paßgang.
457 * Moved the last three navigation-bar links (docs, FAQ and SF) to
458 a new config parameter $Conf{CgiNavBarLinks}. This allows
459 these links to be locally configured. Based on a patch
460 submitted by Ralph Paßgang.
462 * Allow the navigation bar search box to be disabled by
463 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
464 submitted by Ralph Paßgang.
466 * Updates to de.pm from Ralph Paßgang.
468 * Made the BackupPC icon a link to the SF BackupPC project page.
470 #------------------------------------------------------------------------
471 # Version 2.1.0beta1, 4 Apr 2004
472 #------------------------------------------------------------------------
474 * The CSS definition has been removed from the config.pl file and
475 is now a separate file, BackupPC_stnd.css. A new config variable,
476 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
477 Suggested by Ender Mathias.
479 * Fixed the filling of the host name select box for admins.
480 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
481 Reported by Doug Lytle.
483 * Cleaned up warning message for restore using rsync when checksum
484 caching is on, but when file didn't have cached checksums.
486 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
487 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
489 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
490 giving a significant performance improvement. Patch submitted by
493 * Allow several BackupPC_nightly processes to run in parallel based
494 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
495 traversal of the pool, reducing the overall run time for
498 * Allow BackupPC_nightly to split the pool traversal across several
499 nightly runs. This improves the running time per night, at the expense
500 of a slight increase in disk storage as unused pool files might not
501 be deleted for a couple of days. Controller by new config setting
502 $Conf{BackupPCNightlyPeriod}.
504 #------------------------------------------------------------------------
505 # Version 2.1.0beta0, 20 Mar 2004
506 #------------------------------------------------------------------------
508 * A failed full dump is now saved as a partial (incomplete) dump,
509 provided it includes some files. This can be used for browsing,
510 restoring etc, and will also form the basis of resuming full
511 dumps. Only one partial is kept, and it is removed as soon
512 as a successful full (or a new partial) is done.
514 * Added support for resuming a full dump for rsync. The partial
515 full is kept, and to resume an incremental is done against the
516 partial, and a full is done for the rest.
518 * Added support for Rsync checksum caching. Rsync checksum are
519 appended to the compressed pool files. This means that block
520 and file checksums do not need to be recomputed on the server
521 when using rsync. Requires a patch to rsync to support fixed
522 checksum seeds. This patch is included in the cygwin-rsyncd
523 release on http://backuppc.sourceforge.net.
525 * Major addition of Archive feature from Josh Marshall. Special
526 clients can be configured to be archive targets (eg: tape drives,
527 CD-R). Any subset of the backup clients can be selected and tar
528 archives are created, optionally compressed and split and written
529 to the output device. Logs are maintained and are browsable.
531 * Major changes from Ryan Kucera to add style sheets to the CGI
532 interface, allowing easy customization. Added new icons and
533 BackupPC logo. Numerous navigation improvements.
535 * Added directory history display to BackupPC_Admin, allowing the
536 user to quickly see which files changed between backups on a
539 * Added exponential expiry option for full dumps. This allows you
542 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
543 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
544 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
545 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
546 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
548 and so on. This allows you, for example, to keep 4 weekly fulls,
549 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
550 16 weeks, for roughly 1 year of history. This works by deleting
551 every other full as each expiry boundary is crossed. Suggested
554 * Added Italian language translation it.pm from Lorenzo Cappelletti.
556 * Major updates to language files for new features and tags changes.
557 Updated makeDist to do pedantic consistency checking of language
560 * Addition of administration options from Paul Lukins. Initial
561 page allows server to be started/stopped/reloaded. This still
562 needs some i18n work. Currently the server start/stop is
565 * Split BackupPC_Admin into a set of modules, one for each major action.
566 Each action is now a seperate module in lib/BackupPC/CGI.
568 * Allow the blackout period begin/end to span midnight. Adapted
569 from patch submitted by David Smith.
571 * Allow multiple blackout periods, with new config variable
572 $Conf{BlackoutPeriods} that replaces the old variables
573 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
574 $Conf{BlackoutWeekDays}. Based on patch submitted by
577 * Disabled alarms after forks to avoid timeouts in children that
578 do not reset their alarm. Prompted by ideas from James Leu.
580 * Added options for block size, buffer size and share wild-card to
581 BackupPC_tarCreate. Also added negative backup number options
582 that are relative to the last (so -1 is the last), suggested by
583 William McKee and Carl Soderstrom.
585 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
586 the user is more likely to see the error with BackupPC_tarCreate.
587 Reported by Paul Fox.
589 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
590 case it doesn't already exist.
592 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
593 SI Reasoning and Niranjan Ghate.
595 * Changed restore code so that option #1 (direct restore) can be
596 disabled if the restore command is undefined. Disabling direct
597 restore is necessary if the share is read-only. Suggested by
600 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
601 a decimal point or comma for international versions of Samba.
602 Patch submitted by Frank Gard.
604 * Browsing and directory history now sort the files in a
605 case-insensitive manner.
607 * Changed exec() syntax to allow executing commands whose path
610 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
611 is zero or undefined. The protects the existing backups in the
612 case of a bad config.pl file. Suggested by Christian Warden.
614 * Swapped the Server and Hosts sections on the Nav bar. Moved the
615 host search text box to the top of the hosts section. This was
616 done to move the variable-length part of the Nav bar (when all
617 hosts are displayed) to the bottom.
619 * Fixed a bug in tar restore related to how the common prefix path is
620 removed. Now ensure that the common path is at a directory boundary.
621 Reported by Patrick Neuner.
623 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
624 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
626 * Added Suse notes to init.d/README from Bruno Vernay.
628 * Added Apache 2 documentation fix from Michael Tuzi.
630 #------------------------------------------------------------------------
631 # Version 2.0.2, 6 Oct 2003
632 #------------------------------------------------------------------------
634 * Fixed stupid last-minute change in octal size conversion in
637 #-----------------------------------------------------------------------
638 # Version 2.0.1, 5 Oct 2003
639 #------------------------------------------------------------------------
641 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
642 files in BackupPC_tarCreate.
644 * Removed smbclient size repair in BackupPC_tarExtract for files
645 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
646 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
647 extacted using smbclient 2.2.x. If you have problems backing up
648 files whose size is between 2GB and 4GB using smbclient 2.2.x
649 you should upgrade smbclient to 3.0, since it now generates
652 * Replace PingClientPath with PingPath in configure.pl.
654 * Removed -T (taint mode) on binaries installed in configure.pl.
656 * Added support for smbclient from samba version 3.0.0.
658 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
661 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
662 if it is not defined. This allows the CGI interface to work
663 when AdminUsers = '*'. Reported by Quentin Arce.
665 * For SMB, code that detected files with a read-locked region (eg:
666 outlook .pst files), removed them and then tried to link with an
667 earlier version was broken. This code missed a step of mangling
668 the file names. This is now fixed. Reported by Pierre Bourgin.
670 * A backup of a share that has zero files is now considered
671 fatal. This is used to catch miscellaneous Xfer errors that
672 result in no files being backed up. A new config parameter
673 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
674 zero to turn off this check. Suggested by Guillaume Filion.
675 Additional change: this check only applies to a full dump.
677 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
678 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
679 smbclient.) Suggested by Guillaume Filion.
681 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
682 the dump is considered failed.
684 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
685 which just included the '/' directory and nothing below. Now it
686 does just --include '/', which should include everything.
689 * Add hostError to DumpPostUserCmd variable substitutions for both dump
692 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
693 makes BackupPC_dump -v work better.
695 * Don't allow browsing with ".." in directory in case a user tries
696 to trick BackupPC_Admin into displaying directories outside where
699 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
700 fixes large file (>2GB) bugs. Large file bugs reported by Steve
703 #------------------------------------------------------------------------
704 # Version 2.0.0, 14 Jun 2003
705 #------------------------------------------------------------------------
707 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
708 Added "no utf8" to all programs, and added binmode() to relevant
711 #------------------------------------------------------------------------
712 # Version 2.0.0beta3, 1 Jun 2003
713 #------------------------------------------------------------------------
715 * Several improvements to restore: cancel now reports the correct
716 message and cleans up correctly.
718 * Rsync with whitespace and wildcard excludes fixed by replacing
719 argList with argList+ in config.pl plus a fix to Lib.pm for
720 shell escaping array arguments.
722 * Fixed rsync restore for character and block special devices
723 (major and minor device numbers weren't correctly restored).
725 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
727 * (Re)-fixed "Bad command" in log file when restore via tar or zip
728 file download is done.
730 * Added untaint to exec in Lib.pm to avoid tainted errors.
732 * Applied additional tweak to hilight patch from Tim Demarest.
734 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
737 * Don't display RsyncdPasswd when displaying config.pl files.
739 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
740 which increases typical buffering from 4K to 16K-64K. This improves the
743 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
744 then a warning is printed.
746 #------------------------------------------------------------------------
747 # Version 2.0.0beta2, 11 May 2003
748 #------------------------------------------------------------------------
750 * Added German translation, provided by Manfred Herrmann.
752 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
754 * Fixed zip and tar file download from CGI under mod_perl. Reported
755 by Pierre Bourgin and Paul Lukins.
757 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
758 Reported by several users.
760 * Added -v option to BackupPC_dump for verbose output (useful when
761 you run the command manually). Added messages for all exits.
763 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
764 now returns the first IP address that matches the subnet mask.
765 Suggested by Tim Demarest.
767 * Fixed BackupPC::View so the top-level directory is handled correctly.
768 This allows the top-level share/directory to be restored via the
769 CGI interface. Reported by several users.
771 * Fixed RsyncFileIO failures on certain large files by replacing seek()
772 with sysseek(). Reported by Manfred Herrmann.
774 * Added configurable highlighting of PC status in the CGI summary
775 screen; submitted by Tim Demarest.
777 * Fixed command queue CGI display; submitted by Tim Demarest.
779 * BackupPC_trashClean now logs an error if it can't remove all the
780 trash and then goes back to sleep, rather than continually trying.
782 * Moved correct user (uid) check into BackupPC::Lib so that all
783 applications do a user check if $Cong{BackupPCUserVerify} is
784 set. The avoids the risk of manually running BackupPC_dump as
787 * Loss of blackout now applies to "host not found" as well as no ping.
788 Reported by Dale Renton.
790 * "Host not found" is now treated in a similar manner to "no ping".
792 * Added suse-linux init.d script from Leon Letto.
794 * Added Gentoo linux init.d script from Tim Demarest.
796 * Applied additional i18n strings from GFK and the translation team.
798 * Fixed option parsing so that getopts errors are reported and we exit.
800 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
802 #------------------------------------------------------------------------
803 # Version 2.0.0beta1, 30 Mar 2003
804 #------------------------------------------------------------------------
806 * Added Spanish translation es.pm from Javier Gonzalez.
808 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
809 when directories were selected in a certain order.
811 * Fixed BackupPC::PoolWrite so that it can recover when the initial
812 file size is wrong. This is needed since rsync could write a file
813 whose size is different from the initial size returned in the
814 file list when that file is updated while rsync is running.
816 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
817 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
818 helps, but it should be benign. See:
819 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
821 #------------------------------------------------------------------------
822 # Version 2.0.0beta0, 23 Feb 2003
823 #------------------------------------------------------------------------
825 * Support for rsync and rsyncd backup and restore. Changes to
826 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
827 and BackupPC::Xfer::RsyncFileIO.
829 * Added internationalization (i18n) code from Xavier Nicollet,
830 with additions from Guillaume Filion. Voila! BackupPC_Admin
831 now supports English and French, and adding more languages is
832 now easy. New config paramater $Conf{Language} sets the language.
834 * Added optional user-defined pre/post dump/restore commands, allowing
835 things like database shutdown/startup for dumps.
837 * Changed the way hosts are found.
839 * Added $Conf{ClientNameAlias}, which allows the name of the physical
840 client machine to be set. This allows several different backup
841 "hosts" to all refer to the same physical machine, which is
842 convenient if several different types of data need to be backed
843 up, or if different parameters are needed for different parts of
846 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
847 $Conf{NmbLookupCmd} allowing all these commands to be fully
848 configured. Also, all commands can also now be fragments of
851 * Moved all smbclient commands into the config.pl file so the specific
852 arguments can be customized. New config parameters are
853 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
854 $Conf{SmbClientRestoreCmd}.
856 * Added new BackupPC::View module that creates views of backups
857 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
858 and BackupPC_tarCreate to use BackupPC::View. This removes lots
859 of merging and mangling code from the higher-level code.
861 * Added code from Toby Johnson that allows additional users to be
862 specified in the hosts file; these users can also view/start/stop
863 and restore backups for that host. Also added a new config
864 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
865 be listed in the left nav bar for admins.
867 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
868 the maximum number of hardlinks per file in the pool. If a file
869 ever gets to this number of links a new pool file is created to
870 handle additional links.
872 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
873 modules to be loaded.
875 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
876 allow language-specific default messages to be overridden.
878 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
879 files to be represented in the attrib file correctly.
881 * Added support for environment variable BPC_SMB_PASSWD, which is the
882 client's smb password. This overrides the old environment variable
885 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
887 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
888 handle files with trailing spaces.
890 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
891 to ignore multiple signals of the same type.
893 * Added reporting of the largest number of hardlinks in the pool to the
896 * Adding reporting of syntax errors in the per-PC config.pl file.
898 * Updated BackupPC_sendEmail to handle language-specific email messages.
900 * Allow client (host) names to contain spaces. Spaces in host names
901 need to be escaped via "\" in the hosts file. The user of spaces in
902 host names is discouraged, but they should work. One feature that
903 doesn't work with host names that contain spaces is the highlighting
904 of that name in the log file display in the CGI interface. There are
905 no plans to fix this.
907 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
909 * Fixed all open() calls to use 3 argument form to fix handling of file
910 names with trailing whitespace. Also fixed CGI interface so these
911 file names are displayed correctly.
913 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
914 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
915 Reported by Pascal Schelcher. Fixed similar problem reported by
918 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
919 suggested by Tim Demarest.
921 #------------------------------------------------------------------------
922 # Version 1.5.0, 2 Aug 2002
923 #------------------------------------------------------------------------
925 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
926 option instead of --newer-mtime. Also removed --atime-preserve from
927 $Conf{TarClientCmd}. This makes the default settings work better
930 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
931 so it can correctly warn the user to stop it before upgrading. Reported
934 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
935 Reported by Guillaume Filion.
937 * Added LDAP setup to documentation from David Holland.
939 * Tar.pm now adds a "." to file paths that start with "/", so that all
940 tar paths are relative. From Ludovic Drolez.
942 #------------------------------------------------------------------------
943 # Version 1.5.0beta0, 30 Jun 2002
944 #------------------------------------------------------------------------
946 * A full set of restore options is now supported, including direct
947 restore via smbclient or tar or downloading a zip or tar file.
949 * Major additions to CGI script to support better directory navigation,
950 restore features and mod_perl. Also, file downloads from the CGI
951 interface now correctly preserve the file name and provide the
952 correct Content-Type for the most common types of files. Improved
953 directory navigation was contributed by Ryan Kucera.
955 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
956 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
957 create a zip archive of any portion of a backup.
959 * Substantial additions to BackupPC_tarCreate to support restore,
960 including modifying path names, handling hardlinks, fixing
961 support of old backups without attributes (pre-v1.4.0). Plus
962 BackupPC_tarCreate is now an offical part of the release.
963 (Lack of support for hardlinks was reported by John Stanley.)
965 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
968 * A unix domain socket is now used for communication between the CGI
969 interface and BackupPC. The original TCP socket is optional. Sockets
970 are correctly re-initialized if config.pl is updated with new socket
973 * For improved security messages over the unix or TCP socket are protected
974 via an MD5 digest based on a shared secret, a sequence number, a time
975 stamp and a unique per-connection number.
977 * Additions to configure.pl to support install of directory navigation
980 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
981 were set to a single string or list (in v1.4.0 only the case of
982 hash worked correctly). Reported by Phillip Bertolus.
984 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
985 client always subject to blackout, matching the comments in config.pl.
986 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
987 reported by Pascal Schelcher.
989 * Fixed byte and file totals for tar backups, reported by several users.
991 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
992 suggested by Erminio Baranzini.
994 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
995 well as shell escaping of tar arguments.
997 * Fixed entity encoding of 8-bit characters in the CGI interface.
999 * Added optional CGI headers in $Conf{CgiHeaders} that by default
1000 is set to a no-cache pragma. Suggested by Benno Zuure.
1002 #------------------------------------------------------------------------
1003 # Version 1.4.0, 16 Mar 2002
1004 #------------------------------------------------------------------------
1006 * BackupPC now supports tar (in addition to smb) for extracting host
1007 data. This is the most convenient option for linux/unix hosts.
1008 Tar can be configured to run over ssh, rsh or to backup a local
1009 nfs mount from the host.
1011 * Support for special files, including symbolic links, fifo, character
1012 and block device files has been added, so that all native linux/unix
1013 file types can be correctly backed up when using tar transport.
1014 Special files are all stored as regular files and the type attributes
1015 are used to remember the original file type.
1017 * All unix file attributes are now saved (and pooled when possible).
1018 This includes user and group ownership, permissions, and modification
1019 time. Smbclient also does a reasonable job of emulating unix
1020 permissions (such as mtime), and these attributes get saved too.
1022 * The new default is to not fill incremental dumps. configure.pl
1023 automatically sets $Conf{IncrFill} to 0. The default was 1
1024 (incrementals were filled with hardlinks). Since the CGI
1025 script does filling at browsing time, there is no need to
1026 fill incremental dumps.
1028 * Backup file names are now stored in "mangled" form. Each node of a
1029 path is preceded by "f", and special characters (\n, \r, % and /) are
1030 URI-encoded as "%xx", where xx is the ascii character's hex value. So
1031 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
1032 was done mainly so meta-data could be stored alongside the backup
1033 files without name collisions. In particular, the attributes for the
1034 files in a directory are stored in a file called "attrib", and
1035 mangling avoids file name collisions (I discarded the idea of having
1036 a duplicate directory tree for every backup just to store the
1037 attributes). Other meta-data (eg: rsync checksums) could be stored in
1038 file names preceded by, eg, "c". There are two other benefits to
1039 mangling: the share name might contain "/" (eg: "/home/craig" for tar
1040 transport), and I wanted that represented as a single level in the
1041 storage tree. Secondly, as files are written to NewFileList for later
1042 processing by BackupPC_link, embedded newlines in the file's path
1043 will cause problems which are avoided by mangling.
1045 The CGI script undoes the mangling, so it is invisibe to the user.
1046 Of course, old (unmangled) backups are still supported by the CGI
1049 * Various changes to the CGI interface, BackupPC_Admin:
1051 + Added button that allows users to manually start a full dump in
1052 addition to the existing incremental dump.
1054 + Added display of file attributes when browsing backups.
1056 + Added an optional holdoff time specified by the user when canceling
1057 a backup. BackupPC will not attempt any new backups for at least the
1058 specified time. This holdoff time can be changed whether or not a
1061 + Added supports for file mangling, and correct merging of unfilled
1062 backups from mangled or unmangled (and compressed or uncompressed)
1063 fulls when browsing or restoring.
1065 + Only displays a "Start Incr Backup" button if there are already some
1068 + For DHCP hosts, when a user tries to manually start a backup, add
1069 a check for the netbios name of both the host the request came
1070 from (REMOTE_ADDR) and the last known DHCP address for that host
1071 to see if either address matches the host. If not, an error
1072 message is display. The previous behavior was that only requests
1073 from the client itself succeeded, and requests from other machines
1076 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
1077 is 1.4.0. The first digit is for major new releases, the middle digit
1078 is for significant feature releases and improvements, and the last
1079 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
1080 and 1.03 as 1.0.0, ..., 1.3.0.
1082 * BackupPC and the CGI script BackupPC_Admin now check that the effective
1083 user id is correct to avoid accidentally launching BackupPC as the
1084 wrong user or detecting CGI configuration problems. This behavior
1085 can be turned off using the $Conf{BackupPCUserVerify} option.
1087 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
1088 support generic names for both smb and tar transport methods. The
1089 CGI script checks for old names for backward compatibility.
1091 * Major changed to Backup_dump to support new tar transport. All transport
1092 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
1095 * Added workaround for a bug in Samba's smbclient for files between 2GB
1096 and 4GB. The file size in the tar header is incorrect. This allows
1097 files up to 4GB to work with smbclient, rather than 2GB. To support
1098 files larger than 2GB you must make sure perl is compiled with the
1099 uselargefiles option (use "perl -V | egrep largefiles" to check) and
1100 the pool directory must be on a file system that supports large files.
1102 * Moved the pool writing code into a module BackupPC::PoolWrite. This
1103 allows the clever file pool checking (digest, uncompressing, comparing
1104 etc with minimum disk IO) to be used easily in multiple places (eg: it
1105 is now used for writing attribute files so they can be pooled).
1107 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
1109 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
1110 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
1111 on one user's machine was world writable and perl -T correctly
1112 complained about it.
1114 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
1115 Thanks to Kyle Amon for sending the fix. Decided to move the
1116 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
1117 now configure.pl tries to come up with a sensible default based on
1120 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
1121 share name (eg: C$). Thanks to Jules Agee for this fix. Also
1122 changed the default config.pl so that single quotes are used
1123 everywhere so that people don't get tripped up putting '$' inside
1124 double-quoted strings.
1126 #------------------------------------------------------------------------
1127 # Version 1.03, 9 Dec 2001
1128 #------------------------------------------------------------------------
1130 * BackupPC now has full support for compression. There are now two
1131 pool areas, the original pool for uncompressed files, and cpool for
1132 compressed files. The compression is done by Compress::Zlib.
1133 Compression reduces the pool disk usage by around 40%, although your
1134 mileage may vary. Compression is optional and can also be specified on
1135 a per-PC basis (although this will cost more pool storage since many
1136 backup files will have to be stored in both compressed and
1139 * A new script, BackupPC_compressPool, can be run to compress the entire
1140 pool. This is used once to migrate all the pool data from uncompressed
1141 to compressed on existing installations. Read the documentation
1142 (Installing BackupPC/Compressing an existing pool) before running
1143 BackupPC_compressPool!
1145 Alternatively, compression can simply be turned on and all new backups
1146 will be compressed. Both old (uncompressed) and new (compressed)
1147 backups can be browsed and viewed. Eventually, the old backups will
1148 expire and all the pool data will be compressed. However, until the
1149 old backups expire, this approach could require 60% or more additional
1150 pool storage space to store both uncompressed and compressed versions
1151 of the backup files.
1153 * Significant improvements to the cgi interface, BackupPC_Admin:
1155 - much better layout navigation
1156 - handles compressed backup files and compressed log files
1157 - handles unfilled incremental dumps
1158 - better backup directory browsing navigation
1159 - reports compression statistics
1160 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
1161 - Additional customization with $Conf{CgiHeaderFontType},
1162 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
1163 $Conf{CgiHeaderBgColor}.
1165 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
1166 file and queues the PCs itself. Like config.pl, BackupPC will
1167 re-read the hosts file on each wakeup if its modification time
1168 changes, or upon a SIGHUP. This also makes for better behavior
1169 when adding a host: if you add hosts, simply send a SIGHUP to
1170 BackupPC or wait for the next wakeup.
1172 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
1174 * BackupPC_dump keeps track of compressed file sizes so that compression
1175 statistics can be reported by the cgi interface.
1177 * Aging of old log files now handles compressed log files (.z extension).
1179 * Added configuration option $Conf{IncrFill} to specify whether
1180 incremental dumps should be filled in. Old behavior was that
1181 filling was on. Now it's optional. See config.pl for more
1184 * BackupPC_nightly now cleans and generates statistics for both
1185 the uncompressed pool and compressed pool (cpool).
1187 * Added new utility script BackupPC_zcat that can be used to
1188 uncompresses BackupPC files.
1190 * configure.pl offers various options related to compression,
1191 depending upon whether this is a new install or upgrade,
1192 and whether or not Compress::Zlib is installed.
1194 * configure.pl now makes a backup copy of config.pl before
1195 config.pl is updated.
1197 * added three new fields to the backups file to handle optional
1198 filling and compression stats.
1200 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
1201 on each dhcp host once each night to verify that very old backups are
1202 expired. This ensures that very old backups are expired even if
1203 the dhcp host has not been on the network for a long time.
1205 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
1206 even if compression was off. Thanks to Steve Holmes for reporting
1209 * fixed bug that caused a BackupPC queue to get blocked when a backup
1210 cancel attempt was made during the BackupPC_link phase.
1212 #------------------------------------------------------------------------
1213 # Version 1.02, 28 Oct 2001.
1214 #------------------------------------------------------------------------
1216 * Added new script BackupPC_tarExtract to extract the smbclient tar
1217 archive. This reduces disk writes by perhaps 90-95% and disk reads by
1218 50%. Previously, tar was used to extract and write everything to disk.
1219 Then BackupPC_dump would read enough of each file to compute the MD5
1220 digest, and then compare the full file with candidate pool files. So
1221 for each 1MB file that matches a single file in the pool, there would
1222 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
1224 BackupPC_tarExtract instead extracts the archive using a 1MB memory
1225 buffer. This allows the MD5 digest to be computed without touching the
1226 disk. Next, any potential pool file compares are done by comparing the
1227 pool file against the incoming tar data in memory, which only requires
1228 the pool file to be read. So for each 1MB file that matches a single
1229 file in the pool, there are now no disk writes, and only 1MB of reads.
1230 BackupPC_tarExtract handles arbitrary size files and repeated
1231 potential pool matches. If the incoming file doesn't match the pool
1232 then it is written to disk (once the pool is mature this happens maybe
1235 * Substantial changes to BackupPC_dump:
1237 + BackupPC_tarExtract is now used in place of tar.
1239 + BackupPC_dump now reads the output from both smbclient and
1240 BackupPC_tarExtract and merges them into SmbLOG.
1242 + Named pipes are no longer used to connect smbclient to tar
1243 (now BackupPC_tarExtract). Regular pipes are used instead.
1244 This avoids the need to system mknod or mkfifo.
1246 + Locked files on the client that can't be read by smbclient
1247 previously were filled with 0x0 bytes by smbclient, meaning
1248 tar extracted a useless file filled with 0x0 bytes. Now,
1249 BackupPC_dump watches the output of smbclient and removes
1250 any files that smbclient couldn't read. This avoids storing
1251 useless files. It tries to replace such files with a hard link
1252 to a previous dump. These actions appear in the log file.
1254 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
1255 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
1256 reading and writing compressed and regular files and provides all the
1257 hooks for compression support in BackupPC (should be supported in next
1258 version). BackupPC::FileIO also does efficient writing of files that
1259 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
1260 helpful when smbclient reads a locked file, and it fills the tar
1261 output with a file of the correct size but all 0x0. Such files will be
1262 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
1263 writes such files efficiently (as sparse files), meaning just a few
1264 blocks of disk space will be needed even if the file is large.
1266 * alive/dead counting for blackout now works correctly for DHCP hosts.
1268 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
1269 killed and restarted with backups running.
1271 * added extra non blocking select() in BackupPC to make sure the socket
1274 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1276 * Updated BackupPC_sendEmail to correctly parse the locked file
1277 error from 2.2.1a smbclient, so that missing Outlook file emails
1278 can be correctly sent.
1280 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1281 hostname read from the hosts file.
1283 * BackupPC_Admin provides general summary when the host name is empty.
1285 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1287 * configure.pl complains if BackupPC is already running, reminding you
1288 to stop it before upgrading.
1290 * updated documentation, and fixed auto-insertion of config.pl into
1291 BackupPC.pod (previously the last config parameter was left out of
