21 # Version __VERSION__, __RELEASEDATE__
22 #------------------------------------------------------------------------
24 * Removed default paths from conf/config.pl so configure.pl will
25 determine the correct ones at install time. Avoids problem of
26 the config editor complaining about bad executable paths the
27 first time you use it.
29 * Changed first byte of compressed files with rsync checksums appended
30 to 0xd7 to allow correct protocol_version >= 27 md4 checksums to be
31 written. Old cached checksum files have a first byte 0xd6 and are
32 now considered to be uncached. They will be automatically updated
33 as needed. This avoids the cached checksum warnings in beta2.
35 * BackupPC_tarPCCopy now handles all file types correctly. Reported
38 * Fixed BackupPC_nightly to finish pending deletes before renaming
41 * Fixes for rsync restore where hardlink is to file outside of the
42 top-level restore directory. Reported by George Avrunin, who helped
45 * Fixes for checksum mismatch on restore for certain file sizes.
46 Reported by George Avrunin and others.
48 * Fix for config.pl writing code to handle multi-line expressions.
49 Reported by David Relson and others.
51 * Fix for CGI editor when deleting hash entries whose keys are
52 non alphanumeric. Report by David Relson and Aaron Ciarlotta.
54 * Two fixes to configure.pl from Andreas Vögele.
56 #------------------------------------------------------------------------
57 # Version 3.0.0beta2, 18 Nov 2006
58 #------------------------------------------------------------------------
60 * Fix for final md4 digest check on rsync transfers >= 512MB when protocol
61 version >= 27 and checksums are not cached. Reported by Garith Dugmore
64 * Config Editor "Save" button is now always visible, but greyed out
65 until there are changes to save.
67 * Config editor allows other tabs to be selected when there is an
68 error, which allows you to fix an error (eg: missing binary) in
69 an exiting config file. Errors are now displayed at the top of
70 the page in addition to next to the erroneous setting.
72 * configure.pl checks version of Encode.pm. Reported by Chris Stone.
74 * Several fixes to bin/BackupPC_fixupBackupSummary from Stian Jordet.
76 * Fixed config.pl editor writing to solve bug with multi-line text
77 strings ending in newline. Reported and root caused by Les Stott
80 * Fixed error recovery case in BackupPC::PoolWrite, reported by
83 * Fixed table width in backup browsing to avoid Firefox layout anomoly,
84 provided by Jono Woodhouse.
86 * CSS file updates from Jono Woodhouse. Prior (v2) version is included
87 as BackupPC_stnd_orig.css in case people prefer the old skin.
89 * More compact host summary, including disabled host indication,
92 * New directory/file/hardlink and symlink image icons from Sean Cameron
93 and Jono Woodhouse, making directory browse more compact.
95 * BackupPC.pid is now world readable, suggested by Casper Thomsen.
97 * Reordered the Server navigation bar links, suggested by David Relson.
99 * Fixed typos in init.d/src/gentoo-backuppc, configure.pl and config.pl
100 reported by David Relson.
102 #------------------------------------------------------------------------
103 # Version 3.0.0beta1, 30 Jul 2006
104 #------------------------------------------------------------------------
106 * Fixed several Xfer charset conversions.
108 * Added some CGI utf8 conversions from Rodrigo Real and Vincent
111 * Rsync transfers now correctly handle file names with \n or \r.
113 * Host name is forced to lower case, to match 2.x.
115 * Fixed LOG file naming in BackupPC_restore and BackupPC_archive.
117 * GFK applied fr.pm corrections from Nicolas Stransky.
119 * Updated init.d/src scripts for FHS (ie: replaced __TOPDIR__/log
120 with __LOGDIR__ and __TOPDIR__/conf with __CONFDIR__). Patch
121 provided by Rodrigo Real.
123 * Added --log-dir and --conf-dir options to configure.pl.
124 Reported by Vincent Fleuranceau.
126 * Updated File::RsyncP version check in configure.pl, reported
127 by Vincent Fleuranceau. Changed File::RsyncP version to 0.64.
129 #------------------------------------------------------------------------
130 # Version 3.0.0beta0, 11 Jul 2006
131 #------------------------------------------------------------------------
133 * Added configuration and host CGI editor.
135 * Added rsync hardlink support. Requires latest version of
138 * Decoupled BackupPC_dump from BackupPC_nightly by making
139 asynchronous file linking/delete robust to race conditions.
140 Now only BackupPC_nightly and BackupPC_link are mutually
141 exclusive so only one runs at a time, and BackupPC_dump and
142 BackupPC_restore can run anytime.
144 * Added support for multi-level incrementals. In the style of dump(1),
145 the level of each incremental can be specified. Each incremental
146 backups up everything since the most recent backup of a lower level
147 (fulls are always level 0). Previous behavior was all incrementals
148 were level 1, meaning they backed up everything since the last full
149 (level 0). Default configuration is all incrementals are level 1.
151 * Server file names are now in utf8 and optional conversion
152 to/from client name charsets can be configured. All CGI pages
153 now use the utf8 charset.
155 * Backup metadata is now additionally saved to pc/HOST/nnn/backupInfo,
156 in addition to pc/HOST/backups. In case pc/HOST/backups gets trashed,
157 then a new script BackupPC_fixupBackupSummary can read the per-backup
158 metadata from pc/HOST/nnn/backupInfo and reconstruct the backups file.
159 Roberto Moreno also pointed out an early error in the CVS version.
161 * Added Storage module and Storage::Text which localizes all the
162 text data file reading/writing (eg: backups, restores, archives
163 and config.pl files). Added read verify after all write
164 operations for robustness. Additional backends (eg: SQL)
165 can be added in the future as new subclasses of the Storage
168 * Added Config module, and Config::Meta that contains meta data
169 about configuration parameters.
171 * Added RSS support from Rich Duzenbury.
173 * Translations of new 3.0 language strings from Guillaume Filion,
174 Reginaldo Ferreira, Ralph Passgang, Lieven Bridts, Guus Houtzager,
177 * Added optional checking of exit status of Dump/Restore/Archive Pre/Post
178 UserCmd, requested by Kiko Jover, Matthias Bertschy and others.
180 * For new installations configure.pl tries to comply with the file
181 system hierarchy standard, which means all the configuration files
182 below /etc/BackupPC and log files go below /var/log/BackupPC.
184 * Added Slackware init.d script from Tony Nelson.
186 * Fixed error reporting when restore/archive fail to write the
187 request file to the client directory.
189 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
191 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
192 to DumpPreUserCmd etc.
194 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
196 * Jean-Michel Beuken reported several bugs in configure.pl in CVS 3.0.0.
198 * Old backup email warnings now ignore partials requested by Samuel Bancal
200 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
201 ignores any file starting with "." in the pc directory when
202 it is generating warnings about old/unused files/directories.
204 * Applied patch from Marc Prewitt to fix host queue order.
206 * Applied Lorenzo Cappelletti's it.pm patch.
208 * Applied Wander Winkelhorst's nl.pm patch.
210 * Applied Alberto Marconi's it.pm patch.
212 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
213 BackupPC_sendEmail to fix bug reported by Dale Renton.
215 * Added fixup of $ENV{REMOTE_USER} to lib/BackupPC/CGI/Lib.pm in the
216 case of using mod_authz_ldap; patch submitted by Alain Perrier.
218 * Added env LC_ALL=C to $Conf{TarClientCmd} and $Conf{TarClientRestoreCmd}
219 to avoid locale problems, suggested by Ludovic Drolez.
221 * Changed ping output parsing to pick out average rtt time, based
222 on patch from Ron Bickers.
224 * Removed leading "./" and top-level "./" directory from
225 zip archives generated by BackupPC_zipCreate. Reported
226 by Josh (hecktarzuli).
228 * BackupPC_tarCreate and BackupPC_zipCreate now allow "@"
229 in share names. Reported by Robert Waldner.
231 * NT_STATUS_INSUFF_SERVER_RESOURCES is now a fatal error for
232 smbclient transfers, suggested by Brian Shand.
234 * Changed bin/BackupPC_archiveHost to use /bin/csh instead of
235 /bin/sh. That way any errors in the pipeline are reported
236 via the exit status, instead of just the last.
238 * Added $Conf{EMailHeaders} for additional email headers, requested
239 by Ludovic Gasc. If the Content-Type charset is set to utf8 then
240 the body of the email is sent in utf8 coding.
242 * Made shareName argument regexp checking more general to allow parens.
244 * Added some debian init.d instructions to init.d/README from
247 * Documentation updates from Richard Ames, JP Vossen, Torsten Finke.
249 #------------------------------------------------------------------------
250 # Version 2.1.2pl2, 18 Jun 2006
251 #------------------------------------------------------------------------
253 * In conf/config.pl, changed --devices to -D in $Conf{RsyncArgs}
254 and $Conf{RsyncRestoreArgs} to fix "fileListReceive failed" and
255 "Can't open .../f%2f for empty output" errors with rsync 2.6.7+.
256 Fix proposed by Justin Pessa and Vincent Ho, and confirmed by
259 * Added patch from Michael (mna.news) to ignore "file is unchanged"
260 message from tar 1.15.x during incremental backups.
262 * Fixed creation of .rsrc directories in bin/BackupPC_tarExtract
263 when used with xtar on MacOS. Reported by Samuel Bancal and
264 Matthew Radey, who helped with debugging.
266 * Fixed bug in BackupPC_tarExtract for files >8GB in size whose
267 lengths are multiples of 256. Reported by Jamie Myers and
268 Marko Tukiainen, who both helped debugging the problem.
270 * Fixed bug in lib/BackupPC/Xfer/RsyncFileIO.pm that caused
271 incorrected deleted attributes to be set in directories
272 where one of the files had an rsync phase 1 retry during
273 an incremental. Reported by Tony Nelson.
275 #------------------------------------------------------------------------
276 # Version 2.1.2, 5 Sep 2005
277 #------------------------------------------------------------------------
279 * Fixed simple but serious bug in bin/BackupPC_tarCreate that prevented
280 hardlinks being saved correctly. Debugged by Michael (mna.news)
281 with several other people.
283 * Fixed serious bug in bin/BackupPC_dump reported/debugged by Dan Niles
284 that can happen when multiple full backups are deleted after
285 $Conf{FullKeepCnt} is changed.
287 * Changed lib/BackupPC/CGI/Lib.pm so that link to "$TopDir/conf/$host.pl"
288 is displayed if it exists. Patch from Andreas Vögele.
290 * Applied daemonize patch to bin/BackupPC from:
291 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=301057
293 * It's now a fatal error if $Conf{CompressLevel} is set, but
294 Compress::Zlib is not found. Before $Conf{CompressLevel} was
295 silently set to 0, which made all the backups uncompressed.
296 That meant the user never knew if they forget to install
297 Compress::Zlib but were expecting compression to be on.
299 * Finally increased $Conf{ClientTimeout} to 72000 (20 hours).
301 * Added sleep 1 in restart() function in init.d/src/gentoo-backuppc,
302 suggested by Jon Hood.
304 * Added $DestDir to the path of the CGI image directory in configure.pl.
305 Patch submitted by Andreas Vögele.
307 * Applied extensive patch to French translation from Frederic Lehobey.
309 * Minor change to Dutch language $Lang{Pool_Stat} from Wander Winkelhorst.
311 * Minor change to French language $Lang{EMailOutlookBackupMesg} and
312 $Lang{EMailOutlookBackupSubj} from Ludovic Gasc.
314 #------------------------------------------------------------------------
315 # Version 2.1.1, 13 Mar 2005
316 #------------------------------------------------------------------------
318 * Fixed bug in top-level restore using rsync XferMethod.
319 BackupPC::View was leaving an extra leading "/" at the start
320 of top-level directories, messing up the FileList sort order.
321 Reported and debugged by Gail Edwards.
323 * Added pathCreate() to BackupPC_tarExtract so that new directories
324 are created. Required for xtar on MacOSX since the virtual resource
325 fork directories (.rsrc) are not explicitly included in the tar
326 archive - just the files below .rsrc are.
328 * Changed $host.$bkupNum.tar$fileExt.* to $host.$bkupNum.tar$fileExt*
329 in $parCmd in bin/BackupPC_archiveHost.
331 * Fixed HostSortCompare() in BackupPC to correctly sort hosts so
332 those with the oldest backups get queued first.
334 * Changed test in BackupPC_sendEmail so that directories/files
335 starting with "." in $TopDir/pc are ignored, rather than
338 * Changed BackupPC_sendEmail to include NT_STATUS_FILE_LOCK_CONFLICT
339 in check for bad outlook files.
341 * Ensure that %Status and %StatusHost are empty if requesting
342 status on hosts in lib/BackupPC/CGI/Lib.pm GetStatusInfo().
343 Fixes problem with new hosts under mod_perl.
345 * Added images/icon-hardlink.gif so that hardlinks show file type icon.
347 #------------------------------------------------------------------------
348 # Version 2.1.0pl1, 15 Aug 2004
349 #------------------------------------------------------------------------
351 * Added fix to nl.pm from Lieven Bridts.
353 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
354 writes the status and shuts down.
356 * Changed BackupPC_nightly so that it doesn't call find() if the
357 directory doesn't exist. This avoids errors in certain versions
358 of perl. Reported by Bernd Rilling.
360 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
361 Reported by Tony Nelson and Jimmy Liang.
363 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
364 reported by Thomas Tempé.
366 * Added newline to "...skipping because of user requested delay..."
367 log message in BackupPC_dump. Reported by Wayne Scott.
369 * Added read file size error checking to BackupPC_tarCreate.
370 Reported by Brandon Evans.
372 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
373 compression is toggled on/off, a compressed backup doesn't link
374 to an uncompressed pool file (and an uncompressed backup doesn't
375 link to a compressed pool file). Reported by Brandon Evans.
377 * Updated documentation with new dirvish URL and a typo from
380 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
381 for hosts that have failed backups. Reported by Simon Kuhn.
383 #------------------------------------------------------------------------
384 # Version 2.1.0, 20 Jun 2004
385 #------------------------------------------------------------------------
387 * Added Dutch translation from Lieven Bridts, with tweaks from
390 * Added PC-specific config file read in CGI/Archive.pm. Patch
393 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
394 Patch from Pete Wenzel.
396 * Cosmetic changes to PC Summary and Log file language strings from
399 * BackupPC::Lib tries to be more careful when renaming the backups
400 file to backups.old. There have been reports of backups being
401 empty, perhaps when the BackupPC data file system fills up.
402 Now backups is not renamed to backups.old if backups is empty.
404 * BackupPC now closes stderr and stdout before renaming and
405 re-opening the log file.
407 * Pre/post backup/restore/archive commands now correctly set
408 "type" to either incr/full/restore/archive, and now cmdType
409 is the type of Pre/post backup/restore/archive command.
411 * BackupPC_archive correctly terminates archive processes on
414 * Updates to BackupPC_stnd.css with absolute font sizes instead
417 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
418 also ensures the full backup is older than the maximum age
419 expected from $Conf{FullPeriod}.
421 #------------------------------------------------------------------------
422 # Version 2.1.0beta2pl1, 30 May 2004
423 #------------------------------------------------------------------------
425 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
427 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
428 since zip file formats don't support earlier dates. Reported
431 * CGI restore via zip and tar now makes sure stderr is ignored
432 when BackupPC_tarCreate and BackupPC_zipCreate are run.
433 Previously any stderr output would get mixed in the archive,
434 corrupting it. Reported by Dan Niles.
436 #------------------------------------------------------------------------
437 # Version 2.1.0beta2, 23 May 2004
438 #------------------------------------------------------------------------
440 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
441 to every share, rather than just the first, in the case where
442 they are arrays and there are multiple shares. Suggested
445 * On the phase 2 retry pass with rsync, verify the cached checksums
446 if checksum caching is turned on. This will catch the case of
447 cached checksums being incorrectly appended to the compressed
448 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
449 so that cached checksums are verified with a selectable probability.
450 Also, increased File::RsyncP version number to 0.51.
452 * configure.pl now supports an optional batch mode. Command-line
453 options are used to specify all the information that configure.pl
454 needs. This is useful for building auto-install packages.
455 Also, configure.pl now includes pod documentation, so you can do
456 "perldoc configure.pl" to see all the command-line options.
457 Suggested, tested and tweaked by Stuart Herbert for possible
460 * At each wakeup, clients are now queued based on how old the most
461 recent backup is. Clients with errors are queued first, with
462 the oldest error times going first. The rest of the clients are
463 queued next, with the clients with the oldest backup going first.
464 Previously the clients were simply queued in alphabetic order.
465 Suggested by Mike Trisko and Tony Nelson.
467 * Added config parameter $Conf{PartialAgeMax} that controls whether
468 partials are saved at all, and if so, whether the partial will be
469 ignored at the next full backup if it is too old.
471 * BackupPC_tarExtract now allows empty archives without reporting
472 an error. Reported by Don Silvia.
474 * Removed Browse Backups link from Nav Bar in Archive Info display.
475 Reported by Ralph PaĂŸgang.
477 * Fixed documentation display for regular users. Reported by Ralph PaĂŸgang.
479 * Status and PC Summary now work for regular users and only show
480 that user's hosts. Server general status information only appears
481 for admins. Suggested by Ralph PaĂŸgang.
483 * Moved the last three navigation-bar links (docs, FAQ and SF) to
484 a new config parameter $Conf{CgiNavBarLinks}. This allows
485 these links to be locally configured. Based on a patch
486 submitted by Ralph PaĂŸgang.
488 * Allow the navigation bar search box to be disabled by
489 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
490 submitted by Ralph PaĂŸgang.
492 * Updates to de.pm from Ralph PaĂŸgang.
494 * Made the BackupPC icon a link to the SF BackupPC project page.
496 #------------------------------------------------------------------------
497 # Version 2.1.0beta1, 4 Apr 2004
498 #------------------------------------------------------------------------
500 * The CSS definition has been removed from the config.pl file and
501 is now a separate file, BackupPC_stnd.css. A new config variable,
502 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
503 Suggested by Ender Mathias.
505 * Fixed the filling of the host name select box for admins.
506 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
507 Reported by Doug Lytle.
509 * Cleaned up warning message for restore using rsync when checksum
510 caching is on, but when file didn't have cached checksums.
512 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
513 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
515 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
516 giving a significant performance improvement. Patch submitted by
519 * Allow several BackupPC_nightly processes to run in parallel based
520 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
521 traversal of the pool, reducing the overall run time for
524 * Allow BackupPC_nightly to split the pool traversal across several
525 nightly runs. This improves the running time per night, at the expense
526 of a slight increase in disk storage as unused pool files might not
527 be deleted for a couple of days. Controller by new config setting
528 $Conf{BackupPCNightlyPeriod}.
530 #------------------------------------------------------------------------
531 # Version 2.1.0beta0, 20 Mar 2004
532 #------------------------------------------------------------------------
534 * A failed full dump is now saved as a partial (incomplete) dump,
535 provided it includes some files. This can be used for browsing,
536 restoring etc, and will also form the basis of resuming full
537 dumps. Only one partial is kept, and it is removed as soon
538 as a successful full (or a new partial) is done.
540 * Added support for resuming a full dump for rsync. The partial
541 full is kept, and to resume an incremental is done against the
542 partial, and a full is done for the rest.
544 * Added support for Rsync checksum caching. Rsync checksum are
545 appended to the compressed pool files. This means that block
546 and file checksums do not need to be recomputed on the server
547 when using rsync. Requires a patch to rsync to support fixed
548 checksum seeds. This patch is included in the cygwin-rsyncd
549 release on http://backuppc.sourceforge.net.
551 * Major addition of Archive feature from Josh Marshall. Special
552 clients can be configured to be archive targets (eg: tape drives,
553 CD-R). Any subset of the backup clients can be selected and tar
554 archives are created, optionally compressed and split and written
555 to the output device. Logs are maintained and are browsable.
557 * Major changes from Ryan Kucera to add style sheets to the CGI
558 interface, allowing easy customization. Added new icons and
559 BackupPC logo. Numerous navigation improvements.
561 * Added directory history display to BackupPC_Admin, allowing the
562 user to quickly see which files changed between backups on a
565 * Added exponential expiry option for full dumps. This allows you
568 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
569 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
570 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
571 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
572 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
574 and so on. This allows you, for example, to keep 4 weekly fulls,
575 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
576 16 weeks, for roughly 1 year of history. This works by deleting
577 every other full as each expiry boundary is crossed. Suggested
580 * Added Italian language translation it.pm from Lorenzo Cappelletti.
582 * Major updates to language files for new features and tags changes.
583 Updated makeDist to do pedantic consistency checking of language
586 * Addition of administration options from Paul Lukins. Initial
587 page allows server to be started/stopped/reloaded. This still
588 needs some i18n work. Currently the server start/stop is
591 * Split BackupPC_Admin into a set of modules, one for each major action.
592 Each action is now a seperate module in lib/BackupPC/CGI.
594 * Allow the blackout period begin/end to span midnight. Adapted
595 from patch submitted by David Smith.
597 * Allow multiple blackout periods, with new config variable
598 $Conf{BlackoutPeriods} that replaces the old variables
599 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
600 $Conf{BlackoutWeekDays}. Based on patch submitted by
603 * Disabled alarms after forks to avoid timeouts in children that
604 do not reset their alarm. Prompted by ideas from James Leu.
606 * Added options for block size, buffer size and share wild-card to
607 BackupPC_tarCreate. Also added negative backup number options
608 that are relative to the last (so -1 is the last), suggested by
609 William McKee and Carl Soderstrom.
611 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
612 the user is more likely to see the error with BackupPC_tarCreate.
613 Reported by Paul Fox.
615 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
616 case it doesn't already exist.
618 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
619 SI Reasoning and Niranjan Ghate.
621 * Changed restore code so that option #1 (direct restore) can be
622 disabled if the restore command is undefined. Disabling direct
623 restore is necessary if the share is read-only. Suggested by
626 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
627 a decimal point or comma for international versions of Samba.
628 Patch submitted by Frank Gard.
630 * Browsing and directory history now sort the files in a
631 case-insensitive manner.
633 * Changed exec() syntax to allow executing commands whose path
636 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
637 is zero or undefined. The protects the existing backups in the
638 case of a bad config.pl file. Suggested by Christian Warden.
640 * Swapped the Server and Hosts sections on the Nav bar. Moved the
641 host search text box to the top of the hosts section. This was
642 done to move the variable-length part of the Nav bar (when all
643 hosts are displayed) to the bottom.
645 * Fixed a bug in tar restore related to how the common prefix path is
646 removed. Now ensure that the common path is at a directory boundary.
647 Reported by Patrick Neuner.
649 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
650 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
652 * Added Suse notes to init.d/README from Bruno Vernay.
654 * Added Apache 2 documentation fix from Michael Tuzi.
656 #------------------------------------------------------------------------
657 # Version 2.0.2, 6 Oct 2003
658 #------------------------------------------------------------------------
660 * Fixed stupid last-minute change in octal size conversion in
663 #-----------------------------------------------------------------------
664 # Version 2.0.1, 5 Oct 2003
665 #------------------------------------------------------------------------
667 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
668 files in BackupPC_tarCreate.
670 * Removed smbclient size repair in BackupPC_tarExtract for files
671 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
672 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
673 extacted using smbclient 2.2.x. If you have problems backing up
674 files whose size is between 2GB and 4GB using smbclient 2.2.x
675 you should upgrade smbclient to 3.0, since it now generates
678 * Replace PingClientPath with PingPath in configure.pl.
680 * Removed -T (taint mode) on binaries installed in configure.pl.
682 * Added support for smbclient from samba version 3.0.0.
684 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
687 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
688 if it is not defined. This allows the CGI interface to work
689 when AdminUsers = '*'. Reported by Quentin Arce.
691 * For SMB, code that detected files with a read-locked region (eg:
692 outlook .pst files), removed them and then tried to link with an
693 earlier version was broken. This code missed a step of mangling
694 the file names. This is now fixed. Reported by Pierre Bourgin.
696 * A backup of a share that has zero files is now considered
697 fatal. This is used to catch miscellaneous Xfer errors that
698 result in no files being backed up. A new config parameter
699 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
700 zero to turn off this check. Suggested by Guillaume Filion.
701 Additional change: this check only applies to a full dump.
703 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
704 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
705 smbclient.) Suggested by Guillaume Filion.
707 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
708 the dump is considered failed.
710 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
711 which just included the '/' directory and nothing below. Now it
712 does just --include '/', which should include everything.
715 * Add hostError to DumpPostUserCmd variable substitutions for both dump
718 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
719 makes BackupPC_dump -v work better.
721 * Don't allow browsing with ".." in directory in case a user tries
722 to trick BackupPC_Admin into displaying directories outside where
725 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
726 fixes large file (>2GB) bugs. Large file bugs reported by Steve
729 #------------------------------------------------------------------------
730 # Version 2.0.0, 14 Jun 2003
731 #------------------------------------------------------------------------
733 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
734 Added "no utf8" to all programs, and added binmode() to relevant
737 #------------------------------------------------------------------------
738 # Version 2.0.0beta3, 1 Jun 2003
739 #------------------------------------------------------------------------
741 * Several improvements to restore: cancel now reports the correct
742 message and cleans up correctly.
744 * Rsync with whitespace and wildcard excludes fixed by replacing
745 argList with argList+ in config.pl plus a fix to Lib.pm for
746 shell escaping array arguments.
748 * Fixed rsync restore for character and block special devices
749 (major and minor device numbers weren't correctly restored).
751 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
753 * (Re)-fixed "Bad command" in log file when restore via tar or zip
754 file download is done.
756 * Added untaint to exec in Lib.pm to avoid tainted errors.
758 * Applied additional tweak to hilight patch from Tim Demarest.
760 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
763 * Don't display RsyncdPasswd when displaying config.pl files.
765 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
766 which increases typical buffering from 4K to 16K-64K. This improves the
769 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
770 then a warning is printed.
772 #------------------------------------------------------------------------
773 # Version 2.0.0beta2, 11 May 2003
774 #------------------------------------------------------------------------
776 * Added German translation, provided by Manfred Herrmann.
778 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
780 * Fixed zip and tar file download from CGI under mod_perl. Reported
781 by Pierre Bourgin and Paul Lukins.
783 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
784 Reported by several users.
786 * Added -v option to BackupPC_dump for verbose output (useful when
787 you run the command manually). Added messages for all exits.
789 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
790 now returns the first IP address that matches the subnet mask.
791 Suggested by Tim Demarest.
793 * Fixed BackupPC::View so the top-level directory is handled correctly.
794 This allows the top-level share/directory to be restored via the
795 CGI interface. Reported by several users.
797 * Fixed RsyncFileIO failures on certain large files by replacing seek()
798 with sysseek(). Reported by Manfred Herrmann.
800 * Added configurable highlighting of PC status in the CGI summary
801 screen; submitted by Tim Demarest.
803 * Fixed command queue CGI display; submitted by Tim Demarest.
805 * BackupPC_trashClean now logs an error if it can't remove all the
806 trash and then goes back to sleep, rather than continually trying.
808 * Moved correct user (uid) check into BackupPC::Lib so that all
809 applications do a user check if $Cong{BackupPCUserVerify} is
810 set. The avoids the risk of manually running BackupPC_dump as
813 * Loss of blackout now applies to "host not found" as well as no ping.
814 Reported by Dale Renton.
816 * "Host not found" is now treated in a similar manner to "no ping".
818 * Added suse-linux init.d script from Leon Letto.
820 * Added Gentoo linux init.d script from Tim Demarest.
822 * Applied additional i18n strings from GFK and the translation team.
824 * Fixed option parsing so that getopts errors are reported and we exit.
826 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
828 #------------------------------------------------------------------------
829 # Version 2.0.0beta1, 30 Mar 2003
830 #------------------------------------------------------------------------
832 * Added Spanish translation es.pm from Javier Gonzalez.
834 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
835 when directories were selected in a certain order.
837 * Fixed BackupPC::PoolWrite so that it can recover when the initial
838 file size is wrong. This is needed since rsync could write a file
839 whose size is different from the initial size returned in the
840 file list when that file is updated while rsync is running.
842 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
843 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
844 helps, but it should be benign. See:
845 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
847 #------------------------------------------------------------------------
848 # Version 2.0.0beta0, 23 Feb 2003
849 #------------------------------------------------------------------------
851 * Support for rsync and rsyncd backup and restore. Changes to
852 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
853 and BackupPC::Xfer::RsyncFileIO.
855 * Added internationalization (i18n) code from Xavier Nicollet,
856 with additions from Guillaume Filion. Voila! BackupPC_Admin
857 now supports English and French, and adding more languages is
858 now easy. New config paramater $Conf{Language} sets the language.
860 * Added optional user-defined pre/post dump/restore commands, allowing
861 things like database shutdown/startup for dumps.
863 * Changed the way hosts are found.
865 * Added $Conf{ClientNameAlias}, which allows the name of the physical
866 client machine to be set. This allows several different backup
867 "hosts" to all refer to the same physical machine, which is
868 convenient if several different types of data need to be backed
869 up, or if different parameters are needed for different parts of
872 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
873 $Conf{NmbLookupCmd} allowing all these commands to be fully
874 configured. Also, all commands can also now be fragments of
877 * Moved all smbclient commands into the config.pl file so the specific
878 arguments can be customized. New config parameters are
879 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
880 $Conf{SmbClientRestoreCmd}.
882 * Added new BackupPC::View module that creates views of backups
883 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
884 and BackupPC_tarCreate to use BackupPC::View. This removes lots
885 of merging and mangling code from the higher-level code.
887 * Added code from Toby Johnson that allows additional users to be
888 specified in the hosts file; these users can also view/start/stop
889 and restore backups for that host. Also added a new config
890 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
891 be listed in the left nav bar for admins.
893 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
894 the maximum number of hardlinks per file in the pool. If a file
895 ever gets to this number of links a new pool file is created to
896 handle additional links.
898 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
899 modules to be loaded.
901 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
902 allow language-specific default messages to be overridden.
904 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
905 files to be represented in the attrib file correctly.
907 * Added support for environment variable BPC_SMB_PASSWD, which is the
908 client's smb password. This overrides the old environment variable
911 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
913 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
914 handle files with trailing spaces.
916 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
917 to ignore multiple signals of the same type.
919 * Added reporting of the largest number of hardlinks in the pool to the
922 * Adding reporting of syntax errors in the per-PC config.pl file.
924 * Updated BackupPC_sendEmail to handle language-specific email messages.
926 * Allow client (host) names to contain spaces. Spaces in host names
927 need to be escaped via "\" in the hosts file. The user of spaces in
928 host names is discouraged, but they should work. One feature that
929 doesn't work with host names that contain spaces is the highlighting
930 of that name in the log file display in the CGI interface. There are
931 no plans to fix this.
933 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
935 * Fixed all open() calls to use 3 argument form to fix handling of file
936 names with trailing whitespace. Also fixed CGI interface so these
937 file names are displayed correctly.
939 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
940 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
941 Reported by Pascal Schelcher. Fixed similar problem reported by
944 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
945 suggested by Tim Demarest.
947 #------------------------------------------------------------------------
948 # Version 1.5.0, 2 Aug 2002
949 #------------------------------------------------------------------------
951 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
952 option instead of --newer-mtime. Also removed --atime-preserve from
953 $Conf{TarClientCmd}. This makes the default settings work better
956 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
957 so it can correctly warn the user to stop it before upgrading. Reported
960 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
961 Reported by Guillaume Filion.
963 * Added LDAP setup to documentation from David Holland.
965 * Tar.pm now adds a "." to file paths that start with "/", so that all
966 tar paths are relative. From Ludovic Drolez.
968 #------------------------------------------------------------------------
969 # Version 1.5.0beta0, 30 Jun 2002
970 #------------------------------------------------------------------------
972 * A full set of restore options is now supported, including direct
973 restore via smbclient or tar or downloading a zip or tar file.
975 * Major additions to CGI script to support better directory navigation,
976 restore features and mod_perl. Also, file downloads from the CGI
977 interface now correctly preserve the file name and provide the
978 correct Content-Type for the most common types of files. Improved
979 directory navigation was contributed by Ryan Kucera.
981 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
982 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
983 create a zip archive of any portion of a backup.
985 * Substantial additions to BackupPC_tarCreate to support restore,
986 including modifying path names, handling hardlinks, fixing
987 support of old backups without attributes (pre-v1.4.0). Plus
988 BackupPC_tarCreate is now an offical part of the release.
989 (Lack of support for hardlinks was reported by John Stanley.)
991 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
994 * A unix domain socket is now used for communication between the CGI
995 interface and BackupPC. The original TCP socket is optional. Sockets
996 are correctly re-initialized if config.pl is updated with new socket
999 * For improved security messages over the unix or TCP socket are protected
1000 via an MD5 digest based on a shared secret, a sequence number, a time
1001 stamp and a unique per-connection number.
1003 * Additions to configure.pl to support install of directory navigation
1006 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
1007 were set to a single string or list (in v1.4.0 only the case of
1008 hash worked correctly). Reported by Phillip Bertolus.
1010 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
1011 client always subject to blackout, matching the comments in config.pl.
1012 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
1013 reported by Pascal Schelcher.
1015 * Fixed byte and file totals for tar backups, reported by several users.
1017 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
1018 suggested by Erminio Baranzini.
1020 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
1021 well as shell escaping of tar arguments.
1023 * Fixed entity encoding of 8-bit characters in the CGI interface.
1025 * Added optional CGI headers in $Conf{CgiHeaders} that by default
1026 is set to a no-cache pragma. Suggested by Benno Zuure.
1028 #------------------------------------------------------------------------
1029 # Version 1.4.0, 16 Mar 2002
1030 #------------------------------------------------------------------------
1032 * BackupPC now supports tar (in addition to smb) for extracting host
1033 data. This is the most convenient option for linux/unix hosts.
1034 Tar can be configured to run over ssh, rsh or to backup a local
1035 nfs mount from the host.
1037 * Support for special files, including symbolic links, fifo, character
1038 and block device files has been added, so that all native linux/unix
1039 file types can be correctly backed up when using tar transport.
1040 Special files are all stored as regular files and the type attributes
1041 are used to remember the original file type.
1043 * All unix file attributes are now saved (and pooled when possible).
1044 This includes user and group ownership, permissions, and modification
1045 time. Smbclient also does a reasonable job of emulating unix
1046 permissions (such as mtime), and these attributes get saved too.
1048 * The new default is to not fill incremental dumps. configure.pl
1049 automatically sets $Conf{IncrFill} to 0. The default was 1
1050 (incrementals were filled with hardlinks). Since the CGI
1051 script does filling at browsing time, there is no need to
1052 fill incremental dumps.
1054 * Backup file names are now stored in "mangled" form. Each node of a
1055 path is preceded by "f", and special characters (\n, \r, % and /) are
1056 URI-encoded as "%xx", where xx is the ascii character's hex value. So
1057 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
1058 was done mainly so meta-data could be stored alongside the backup
1059 files without name collisions. In particular, the attributes for the
1060 files in a directory are stored in a file called "attrib", and
1061 mangling avoids file name collisions (I discarded the idea of having
1062 a duplicate directory tree for every backup just to store the
1063 attributes). Other meta-data (eg: rsync checksums) could be stored in
1064 file names preceded by, eg, "c". There are two other benefits to
1065 mangling: the share name might contain "/" (eg: "/home/craig" for tar
1066 transport), and I wanted that represented as a single level in the
1067 storage tree. Secondly, as files are written to NewFileList for later
1068 processing by BackupPC_link, embedded newlines in the file's path
1069 will cause problems which are avoided by mangling.
1071 The CGI script undoes the mangling, so it is invisibe to the user.
1072 Of course, old (unmangled) backups are still supported by the CGI
1075 * Various changes to the CGI interface, BackupPC_Admin:
1077 + Added button that allows users to manually start a full dump in
1078 addition to the existing incremental dump.
1080 + Added display of file attributes when browsing backups.
1082 + Added an optional holdoff time specified by the user when canceling
1083 a backup. BackupPC will not attempt any new backups for at least the
1084 specified time. This holdoff time can be changed whether or not a
1087 + Added supports for file mangling, and correct merging of unfilled
1088 backups from mangled or unmangled (and compressed or uncompressed)
1089 fulls when browsing or restoring.
1091 + Only displays a "Start Incr Backup" button if there are already some
1094 + For DHCP hosts, when a user tries to manually start a backup, add
1095 a check for the netbios name of both the host the request came
1096 from (REMOTE_ADDR) and the last known DHCP address for that host
1097 to see if either address matches the host. If not, an error
1098 message is display. The previous behavior was that only requests
1099 from the client itself succeeded, and requests from other machines
1102 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
1103 is 1.4.0. The first digit is for major new releases, the middle digit
1104 is for significant feature releases and improvements, and the last
1105 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
1106 and 1.03 as 1.0.0, ..., 1.3.0.
1108 * BackupPC and the CGI script BackupPC_Admin now check that the effective
1109 user id is correct to avoid accidentally launching BackupPC as the
1110 wrong user or detecting CGI configuration problems. This behavior
1111 can be turned off using the $Conf{BackupPCUserVerify} option.
1113 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
1114 support generic names for both smb and tar transport methods. The
1115 CGI script checks for old names for backward compatibility.
1117 * Major changed to Backup_dump to support new tar transport. All transport
1118 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
1121 * Added workaround for a bug in Samba's smbclient for files between 2GB
1122 and 4GB. The file size in the tar header is incorrect. This allows
1123 files up to 4GB to work with smbclient, rather than 2GB. To support
1124 files larger than 2GB you must make sure perl is compiled with the
1125 uselargefiles option (use "perl -V | egrep largefiles" to check) and
1126 the pool directory must be on a file system that supports large files.
1128 * Moved the pool writing code into a module BackupPC::PoolWrite. This
1129 allows the clever file pool checking (digest, uncompressing, comparing
1130 etc with minimum disk IO) to be used easily in multiple places (eg: it
1131 is now used for writing attribute files so they can be pooled).
1133 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
1135 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
1136 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
1137 on one user's machine was world writable and perl -T correctly
1138 complained about it.
1140 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
1141 Thanks to Kyle Amon for sending the fix. Decided to move the
1142 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
1143 now configure.pl tries to come up with a sensible default based on
1146 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
1147 share name (eg: C$). Thanks to Jules Agee for this fix. Also
1148 changed the default config.pl so that single quotes are used
1149 everywhere so that people don't get tripped up putting '$' inside
1150 double-quoted strings.
1152 #------------------------------------------------------------------------
1153 # Version 1.03, 9 Dec 2001
1154 #------------------------------------------------------------------------
1156 * BackupPC now has full support for compression. There are now two
1157 pool areas, the original pool for uncompressed files, and cpool for
1158 compressed files. The compression is done by Compress::Zlib.
1159 Compression reduces the pool disk usage by around 40%, although your
1160 mileage may vary. Compression is optional and can also be specified on
1161 a per-PC basis (although this will cost more pool storage since many
1162 backup files will have to be stored in both compressed and
1165 * A new script, BackupPC_compressPool, can be run to compress the entire
1166 pool. This is used once to migrate all the pool data from uncompressed
1167 to compressed on existing installations. Read the documentation
1168 (Installing BackupPC/Compressing an existing pool) before running
1169 BackupPC_compressPool!
1171 Alternatively, compression can simply be turned on and all new backups
1172 will be compressed. Both old (uncompressed) and new (compressed)
1173 backups can be browsed and viewed. Eventually, the old backups will
1174 expire and all the pool data will be compressed. However, until the
1175 old backups expire, this approach could require 60% or more additional
1176 pool storage space to store both uncompressed and compressed versions
1177 of the backup files.
1179 * Significant improvements to the cgi interface, BackupPC_Admin:
1181 - much better layout navigation
1182 - handles compressed backup files and compressed log files
1183 - handles unfilled incremental dumps
1184 - better backup directory browsing navigation
1185 - reports compression statistics
1186 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
1187 - Additional customization with $Conf{CgiHeaderFontType},
1188 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
1189 $Conf{CgiHeaderBgColor}.
1191 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
1192 file and queues the PCs itself. Like config.pl, BackupPC will
1193 re-read the hosts file on each wakeup if its modification time
1194 changes, or upon a SIGHUP. This also makes for better behavior
1195 when adding a host: if you add hosts, simply send a SIGHUP to
1196 BackupPC or wait for the next wakeup.
1198 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
1200 * BackupPC_dump keeps track of compressed file sizes so that compression
1201 statistics can be reported by the cgi interface.
1203 * Aging of old log files now handles compressed log files (.z extension).
1205 * Added configuration option $Conf{IncrFill} to specify whether
1206 incremental dumps should be filled in. Old behavior was that
1207 filling was on. Now it's optional. See config.pl for more
1210 * BackupPC_nightly now cleans and generates statistics for both
1211 the uncompressed pool and compressed pool (cpool).
1213 * Added new utility script BackupPC_zcat that can be used to
1214 uncompresses BackupPC files.
1216 * configure.pl offers various options related to compression,
1217 depending upon whether this is a new install or upgrade,
1218 and whether or not Compress::Zlib is installed.
1220 * configure.pl now makes a backup copy of config.pl before
1221 config.pl is updated.
1223 * added three new fields to the backups file to handle optional
1224 filling and compression stats.
1226 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
1227 on each dhcp host once each night to verify that very old backups are
1228 expired. This ensures that very old backups are expired even if
1229 the dhcp host has not been on the network for a long time.
1231 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
1232 even if compression was off. Thanks to Steve Holmes for reporting
1235 * fixed bug that caused a BackupPC queue to get blocked when a backup
1236 cancel attempt was made during the BackupPC_link phase.

1242 * Added new script BackupPC_tarExtract to extract the smbclient tar
1243 archive. This reduces disk writes by perhaps 90-95% and disk reads by
1244 50%. Previously, tar was used to extract and write everything to disk.
1245 Then BackupPC_dump would read enough of each file to compute the MD5
1246 digest, and then compare the full file with candidate pool files. So
1247 for each 1MB file that matches a single file in the pool, there would
1248 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
1250 BackupPC_tarExtract instead extracts the archive using a 1MB memory
1251 buffer. This allows the MD5 digest to be computed without touching the
1252 disk. Next, any potential pool file compares are done by comparing the
1253 pool file against the incoming tar data in memory, which only requires
1254 the pool file to be read. So for each 1MB file that matches a single
1255 file in the pool, there are now no disk writes, and only 1MB of reads.
1256 BackupPC_tarExtract handles arbitrary size files and repeated
1257 potential pool matches. If the incoming file doesn't match the pool
1258 then it is written to disk (once the pool is mature this happens maybe
1261 * Substantial changes to BackupPC_dump:
1263 + BackupPC_tarExtract is now used in place of tar.
1265 + BackupPC_dump now reads the output from both smbclient and
1266 BackupPC_tarExtract and merges them into SmbLOG.
1268 + Named pipes are no longer used to connect smbclient to tar
1269 (now BackupPC_tarExtract). Regular pipes are used instead.
1270 This avoids the need to system mknod or mkfifo.
1272 + Locked files on the client that can't be read by smbclient
1273 previously were filled with 0x0 bytes by smbclient, meaning
1274 tar extracted a useless file filled with 0x0 bytes. Now,
1275 BackupPC_dump watches the output of smbclient and removes
1276 any files that smbclient couldn't read. This avoids storing
1277 useless files. It tries to replace such files with a hard link
1278 to a previous dump. These actions appear in the log file.
1280 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
1281 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
1282 reading and writing compressed and regular files and provides all the
1283 hooks for compression support in BackupPC (should be supported in next
1284 version). BackupPC::FileIO also does efficient writing of files that
1285 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
1286 helpful when smbclient reads a locked file, and it fills the tar
1287 output with a file of the correct size but all 0x0. Such files will be
1288 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
1289 writes such files efficiently (as sparse files), meaning just a few
1290 blocks of disk space will be needed even if the file is large.
1292 * alive/dead counting for blackout now works correctly for DHCP hosts.
1294 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
1295 killed and restarted with backups running.
1297 * added extra non blocking select() in BackupPC to make sure the socket
1300 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1302 * Updated BackupPC_sendEmail to correctly parse the locked file
1303 error from 2.2.1a smbclient, so that missing Outlook file emails
1304 can be correctly sent.
1306 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1307 hostname read from the hosts file.
1309 * BackupPC_Admin provides general summary when the host name is empty.
1311 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1313 * configure.pl complains if BackupPC is already running, reminding you
1314 to stop it before upgrading.
1316 * updated documentation, and fixed auto-insertion of config.pl into
1317 BackupPC.pod (previously the last config parameter was left out of

1326 * BackupPC_sendMail now reads the optional per-PC config file, allowing
1327 email configuration parameters to be set on a per-PC basis.
1329 * Removed the unused 4096-length MD5 digest code in lib/BackupPC/Lib.pm.
