21 # Version __VERSION__, __RELEASEDATE__
22 #------------------------------------------------------------------------
24 * Added some performance improvements to BackupPC::Xfer::RsyncFileIO
25 for the case of small files with cached checksums.
27 * Added optional support for IO::Dirent which allows inode information
28 to be extracted from the dirent directory structure. This allows
29 BackupPC to order some directory operations by inode, which on
30 some file systems (eg: ext3) can results in a 20-30% performance
31 gain. On other file systems there is no real improvement. This
32 optimization is turned on automatically if IO::Dirent is installed.
34 * Added sorting by column feature to host summary table in CGI
35 interface. Implemented by Jeremy Tietsort.
37 * Added FreeBSD init.d file provided by Gabriel Rossetti.
39 * Applied small patch from Sergey to lib/BackupPC/Xfer/Tar.pm that makes
40 it ignore "socket ignored" error on incrementals.
42 * Applied small patch from Sergey to bin/BackupPC_archiveHost.
44 * Added RsyncdUserName to the config editor. Reported by Vicent Roca Daniel.
46 * configure.pl clears $Conf{ParPath} if it doesn't point to a valid
49 * Added freebsd-backuppc init.d script from Gabriel Rossetti.
51 * Added documentation for BackupPC_tarPCCopy, including use of -P option
52 to tar suggested by Daniel Berteaud.
54 * Config editor now removes white space at start of exec path.
55 Reported by Christoph Iwasjuta.
57 * CgiDateFormatMMDD == 2 gives a YYYY-MM-DD format for CGI dates,
60 #------------------------------------------------------------------------
61 # Version 3.0.0, 28 Jan 2007
62 #------------------------------------------------------------------------
64 * BackupPC_sendEmail now correctly sends admin email if backups
65 were skipped because the disk was too full, reported by Dan
68 * BackupPC_Admin now uses $Conf{UmaskMode}, so config.pl files
69 written by the editor have more restrictive permissions.
70 Reported by Tim Massey.
72 * Host summary now shows active backups on disabled hosts,
75 * Fixed host LOG link and LOG list order, reported by Tim Massey.
77 * Moved Encode.pm version check to start of configure.pl so it
78 produces a useful error message if Encode.pm is too old.
80 * Fixed hrefs to configuration documentation to handle changes
81 in the way perl generates the anchors. Reported by Philip
84 * Host name links in LOG files now allow "." in the host name.
85 Reported by Jean-Michel Beuken.
87 * Fixes to lib/BackupPC/Xfer/Tar.pm for tar 1.16: allow 1
88 (ie: 256) as a successful exit status and match "Total
89 bytes read" message for restores. First reported by
90 Torsten Sadowski and debugged by Ralf Gross and Holger
93 #------------------------------------------------------------------------
94 # Version 3.0.0beta3, 3 Dec 2006
95 #------------------------------------------------------------------------
97 * Removed default paths from conf/config.pl so configure.pl will
98 determine the correct ones at install time. Avoids problem of
99 the config editor complaining about bad executable paths the
100 first time you use it.
102 * Changed first byte of compressed files with rsync checksums appended
103 to 0xd7 to allow correct protocol_version >= 27 md4 checksums to be
104 written. Old cached checksum files have a first byte 0xd6 and are
105 now considered to be uncached. They will be automatically updated
106 as needed. This avoids the cached checksum warnings in beta2.
108 * BackupPC_tarPCCopy now handles all file types correctly. Reported
111 * Fixed BackupPC_nightly to finish pending deletes before renaming
114 * Fixes for rsync restore where hardlink is to file outside of the
115 top-level restore directory. Reported by George Avrunin, who helped
118 * Fixes for checksum mismatch on restore for certain file sizes.
119 Reported by George Avrunin and others.
121 * Fix for config.pl writing code to handle multi-line expressions.
122 Reported by David Relson and others.
124 * Fix for CGI editor when deleting hash entries whose keys are
125 non alphanumeric. Report by David Relson and Aaron Ciarlotta.
127 * Two fixes to configure.pl from Andreas Vögele.
129 #------------------------------------------------------------------------
130 # Version 3.0.0beta2, 18 Nov 2006
131 #------------------------------------------------------------------------
133 * Fix for final md4 digest check on rsync transfers >= 512MB when protocol
134 version >= 27 and checksums are not cached. Reported by Garith Dugmore
137 * Config Editor "Save" button is now always visible, but greyed out
138 until there are changes to save.
140 * Config editor allows other tabs to be selected when there is an
141 error, which allows you to fix an error (eg: missing binary) in
142 an exiting config file. Errors are now displayed at the top of
143 the page in addition to next to the erroneous setting.
145 * configure.pl checks version of Encode.pm. Reported by Chris Stone.
147 * Several fixes to bin/BackupPC_fixupBackupSummary from Stian Jordet.
149 * Fixed config.pl editor writing to solve bug with multi-line text
150 strings ending in newline. Reported and root caused by Les Stott
153 * Fixed error recovery case in BackupPC::PoolWrite, reported by
156 * Fixed table width in backup browsing to avoid Firefox layout anomoly,
157 provided by Jono Woodhouse.
159 * CSS file updates from Jono Woodhouse. Prior (v2) version is included
160 as BackupPC_stnd_orig.css in case people prefer the old skin.
162 * More compact host summary, including disabled host indication,
165 * New directory/file/hardlink and symlink image icons from Sean Cameron
166 and Jono Woodhouse, making directory browse more compact.
168 * BackupPC.pid is now world readable, suggested by Casper Thomsen.
170 * Reordered the Server navigation bar links, suggested by David Relson.
172 * Fixed typos in init.d/src/gentoo-backuppc, configure.pl and config.pl
173 reported by David Relson.
175 #------------------------------------------------------------------------
176 # Version 3.0.0beta1, 30 Jul 2006
177 #------------------------------------------------------------------------
179 * Fixed several Xfer charset conversions.
181 * Added some CGI utf8 conversions from Rodrigo Real and Vincent
184 * Rsync transfers now correctly handle file names with \n or \r.
186 * Host name is forced to lower case, to match 2.x.
188 * Fixed LOG file naming in BackupPC_restore and BackupPC_archive.
190 * GFK applied fr.pm corrections from Nicolas Stransky.
192 * Updated init.d/src scripts for FHS (ie: replaced __TOPDIR__/log
193 with __LOGDIR__ and __TOPDIR__/conf with __CONFDIR__). Patch
194 provided by Rodrigo Real.
196 * Added --log-dir and --conf-dir options to configure.pl.
197 Reported by Vincent Fleuranceau.
199 * Updated File::RsyncP version check in configure.pl, reported
200 by Vincent Fleuranceau. Changed File::RsyncP version to 0.64.
202 #------------------------------------------------------------------------
203 # Version 3.0.0beta0, 11 Jul 2006
204 #------------------------------------------------------------------------
206 * Added configuration and host CGI editor.
208 * Added rsync hardlink support. Requires latest version of
211 * Decoupled BackupPC_dump from BackupPC_nightly by making
212 asynchronous file linking/delete robust to race conditions.
213 Now only BackupPC_nightly and BackupPC_link are mutually
214 exclusive so only one runs at a time, and BackupPC_dump and
215 BackupPC_restore can run anytime.
217 * Added support for multi-level incrementals. In the style of dump(1),
218 the level of each incremental can be specified. Each incremental
219 backups up everything since the most recent backup of a lower level
220 (fulls are always level 0). Previous behavior was all incrementals
221 were level 1, meaning they backed up everything since the last full
222 (level 0). Default configuration is all incrementals are level 1.
224 * Server file names are now in utf8 and optional conversion
225 to/from client name charsets can be configured. All CGI pages
226 now use the utf8 charset.
228 * Backup metadata is now additionally saved to pc/HOST/nnn/backupInfo,
229 in addition to pc/HOST/backups. In case pc/HOST/backups gets trashed,
230 then a new script BackupPC_fixupBackupSummary can read the per-backup
231 metadata from pc/HOST/nnn/backupInfo and reconstruct the backups file.
232 Roberto Moreno also pointed out an early error in the CVS version.
234 * Added Storage module and Storage::Text which localizes all the
235 text data file reading/writing (eg: backups, restores, archives
236 and config.pl files). Added read verify after all write
237 operations for robustness. Additional backends (eg: SQL)
238 can be added in the future as new subclasses of the Storage
241 * Added Config module, and Config::Meta that contains meta data
242 about configuration parameters.
244 * Added RSS support from Rich Duzenbury.
246 * Translations of new 3.0 language strings from Guillaume Filion,
247 Reginaldo Ferreira, Ralph Passgang, Lieven Bridts, Guus Houtzager,
250 * Added optional checking of exit status of Dump/Restore/Archive Pre/Post
251 UserCmd, requested by Kiko Jover, Matthias Bertschy and others.
253 * For new installations configure.pl tries to comply with the file
254 system hierarchy standard, which means all the configuration files
255 below /etc/BackupPC and log files go below /var/log/BackupPC.
257 * Added Slackware init.d script from Tony Nelson.
259 * Fixed error reporting when restore/archive fail to write the
260 request file to the client directory.
262 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
264 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
265 to DumpPreUserCmd etc.
267 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
269 * Jean-Michel Beuken reported several bugs in configure.pl in CVS 3.0.0.
271 * Old backup email warnings now ignore partials requested by Samuel Bancal
273 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
274 ignores any file starting with "." in the pc directory when
275 it is generating warnings about old/unused files/directories.
277 * Applied patch from Marc Prewitt to fix host queue order.
279 * Applied Lorenzo Cappelletti's it.pm patch.
281 * Applied Wander Winkelhorst's nl.pm patch.
283 * Applied Alberto Marconi's it.pm patch.
285 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
286 BackupPC_sendEmail to fix bug reported by Dale Renton.
288 * Added fixup of $ENV{REMOTE_USER} to lib/BackupPC/CGI/Lib.pm in the
289 case of using mod_authz_ldap; patch submitted by Alain Perrier.
291 * Added env LC_ALL=C to $Conf{TarClientCmd} and $Conf{TarClientRestoreCmd}
292 to avoid locale problems, suggested by Ludovic Drolez.
294 * Changed ping output parsing to pick out average rtt time, based
295 on patch from Ron Bickers.
297 * Removed leading "./" and top-level "./" directory from
298 zip archives generated by BackupPC_zipCreate. Reported
299 by Josh (hecktarzuli).
301 * BackupPC_tarCreate and BackupPC_zipCreate now allow "@"
302 in share names. Reported by Robert Waldner.
304 * NT_STATUS_INSUFF_SERVER_RESOURCES is now a fatal error for
305 smbclient transfers, suggested by Brian Shand.
307 * Changed bin/BackupPC_archiveHost to use /bin/csh instead of
308 /bin/sh. That way any errors in the pipeline are reported
309 via the exit status, instead of just the last.
311 * Added $Conf{EMailHeaders} for additional email headers, requested
312 by Ludovic Gasc. If the Content-Type charset is set to utf8 then
313 the body of the email is sent in utf8 coding.
315 * Made shareName argument regexp checking more general to allow parens.
317 * Added some debian init.d instructions to init.d/README from
320 * Documentation updates from Richard Ames, JP Vossen, Torsten Finke.
322 #------------------------------------------------------------------------
323 # Version 2.1.2pl2, 18 Jun 2006
324 #------------------------------------------------------------------------
326 * In conf/config.pl, changed --devices to -D in $Conf{RsyncArgs}
327 and $Conf{RsyncRestoreArgs} to fix "fileListReceive failed" and
328 "Can't open .../f%2f for empty output" errors with rsync 2.6.7+.
329 Fix proposed by Justin Pessa and Vincent Ho, and confirmed by
332 * Added patch from Michael (mna.news) to ignore "file is unchanged"
333 message from tar 1.15.x during incremental backups.
335 * Fixed creation of .rsrc directories in bin/BackupPC_tarExtract
336 when used with xtar on MacOS. Reported by Samuel Bancal and
337 Matthew Radey, who helped with debugging.
339 * Fixed bug in BackupPC_tarExtract for files >8GB in size whose
340 lengths are multiples of 256. Reported by Jamie Myers and
341 Marko Tukiainen, who both helped debugging the problem.
343 * Fixed bug in lib/BackupPC/Xfer/RsyncFileIO.pm that caused
344 incorrected deleted attributes to be set in directories
345 where one of the files had an rsync phase 1 retry during
346 an incremental. Reported by Tony Nelson.
348 #------------------------------------------------------------------------
349 # Version 2.1.2, 5 Sep 2005
350 #------------------------------------------------------------------------
352 * Fixed simple but serious bug in bin/BackupPC_tarCreate that prevented
353 hardlinks being saved correctly. Debugged by Michael (mna.news)
354 with several other people.
356 * Fixed serious bug in bin/BackupPC_dump reported/debugged by Dan Niles
357 that can happen when multiple full backups are deleted after
358 $Conf{FullKeepCnt} is changed.
360 * Changed lib/BackupPC/CGI/Lib.pm so that link to "$TopDir/conf/$host.pl"
361 is displayed if it exists. Patch from Andreas Vögele.
363 * Applied daemonize patch to bin/BackupPC from:
364 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=301057
366 * It's now a fatal error if $Conf{CompressLevel} is set, but
367 Compress::Zlib is not found. Before $Conf{CompressLevel} was
368 silently set to 0, which made all the backups uncompressed.
369 That meant the user never knew if they forget to install
370 Compress::Zlib but were expecting compression to be on.
372 * Finally increased $Conf{ClientTimeout} to 72000 (20 hours).
374 * Added sleep 1 in restart() function in init.d/src/gentoo-backuppc,
375 suggested by Jon Hood.
377 * Added $DestDir to the path of the CGI image directory in configure.pl.
378 Patch submitted by Andreas Vögele.
380 * Applied extensive patch to French translation from Frederic Lehobey.
382 * Minor change to Dutch language $Lang{Pool_Stat} from Wander Winkelhorst.
384 * Minor change to French language $Lang{EMailOutlookBackupMesg} and
385 $Lang{EMailOutlookBackupSubj} from Ludovic Gasc.
387 #------------------------------------------------------------------------
388 # Version 2.1.1, 13 Mar 2005
389 #------------------------------------------------------------------------
391 * Fixed bug in top-level restore using rsync XferMethod.
392 BackupPC::View was leaving an extra leading "/" at the start
393 of top-level directories, messing up the FileList sort order.
394 Reported and debugged by Gail Edwards.
396 * Added pathCreate() to BackupPC_tarExtract so that new directories
397 are created. Required for xtar on MacOSX since the virtual resource
398 fork directories (.rsrc) are not explicitly included in the tar
399 archive - just the files below .rsrc are.
401 * Changed $host.$bkupNum.tar$fileExt.* to $host.$bkupNum.tar$fileExt*
402 in $parCmd in bin/BackupPC_archiveHost.
404 * Fixed HostSortCompare() in BackupPC to correctly sort hosts so
405 those with the oldest backups get queued first.
407 * Changed test in BackupPC_sendEmail so that directories/files
408 starting with "." in $TopDir/pc are ignored, rather than
411 * Changed BackupPC_sendEmail to include NT_STATUS_FILE_LOCK_CONFLICT
412 in check for bad outlook files.
414 * Ensure that %Status and %StatusHost are empty if requesting
415 status on hosts in lib/BackupPC/CGI/Lib.pm GetStatusInfo().
416 Fixes problem with new hosts under mod_perl.
418 * Added images/icon-hardlink.gif so that hardlinks show file type icon.
420 #------------------------------------------------------------------------
421 # Version 2.1.0pl1, 15 Aug 2004
422 #------------------------------------------------------------------------
424 * Added fix to nl.pm from Lieven Bridts.
426 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
427 writes the status and shuts down.
429 * Changed BackupPC_nightly so that it doesn't call find() if the
430 directory doesn't exist. This avoids errors in certain versions
431 of perl. Reported by Bernd Rilling.
433 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
434 Reported by Tony Nelson and Jimmy Liang.
436 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
437 reported by Thomas Tempé.
439 * Added newline to "...skipping because of user requested delay..."
440 log message in BackupPC_dump. Reported by Wayne Scott.
442 * Added read file size error checking to BackupPC_tarCreate.
443 Reported by Brandon Evans.
445 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
446 compression is toggled on/off, a compressed backup doesn't link
447 to an uncompressed pool file (and an uncompressed backup doesn't
448 link to a compressed pool file). Reported by Brandon Evans.
450 * Updated documentation with new dirvish URL and a typo from
453 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
454 for hosts that have failed backups. Reported by Simon Kuhn.
456 #------------------------------------------------------------------------
457 # Version 2.1.0, 20 Jun 2004
458 #------------------------------------------------------------------------
460 * Added Dutch translation from Lieven Bridts, with tweaks from
463 * Added PC-specific config file read in CGI/Archive.pm. Patch
466 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
467 Patch from Pete Wenzel.
469 * Cosmetic changes to PC Summary and Log file language strings from
472 * BackupPC::Lib tries to be more careful when renaming the backups
473 file to backups.old. There have been reports of backups being
474 empty, perhaps when the BackupPC data file system fills up.
475 Now backups is not renamed to backups.old if backups is empty.
477 * BackupPC now closes stderr and stdout before renaming and
478 re-opening the log file.
480 * Pre/post backup/restore/archive commands now correctly set
481 "type" to either incr/full/restore/archive, and now cmdType
482 is the type of Pre/post backup/restore/archive command.
484 * BackupPC_archive correctly terminates archive processes on
487 * Updates to BackupPC_stnd.css with absolute font sizes instead
490 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
491 also ensures the full backup is older than the maximum age
492 expected from $Conf{FullPeriod}.
494 #------------------------------------------------------------------------
495 # Version 2.1.0beta2pl1, 30 May 2004
496 #------------------------------------------------------------------------
498 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
500 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
501 since zip file formats don't support earlier dates. Reported
504 * CGI restore via zip and tar now makes sure stderr is ignored
505 when BackupPC_tarCreate and BackupPC_zipCreate are run.
506 Previously any stderr output would get mixed in the archive,
507 corrupting it. Reported by Dan Niles.
509 #------------------------------------------------------------------------
510 # Version 2.1.0beta2, 23 May 2004
511 #------------------------------------------------------------------------
513 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
514 to every share, rather than just the first, in the case where
515 they are arrays and there are multiple shares. Suggested
518 * On the phase 2 retry pass with rsync, verify the cached checksums
519 if checksum caching is turned on. This will catch the case of
520 cached checksums being incorrectly appended to the compressed
521 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
522 so that cached checksums are verified with a selectable probability.
523 Also, increased File::RsyncP version number to 0.51.
525 * configure.pl now supports an optional batch mode. Command-line
526 options are used to specify all the information that configure.pl
527 needs. This is useful for building auto-install packages.
528 Also, configure.pl now includes pod documentation, so you can do
529 "perldoc configure.pl" to see all the command-line options.
530 Suggested, tested and tweaked by Stuart Herbert for possible
533 * At each wakeup, clients are now queued based on how old the most
534 recent backup is. Clients with errors are queued first, with
535 the oldest error times going first. The rest of the clients are
536 queued next, with the clients with the oldest backup going first.
537 Previously the clients were simply queued in alphabetic order.
538 Suggested by Mike Trisko and Tony Nelson.
540 * Added config parameter $Conf{PartialAgeMax} that controls whether
541 partials are saved at all, and if so, whether the partial will be
542 ignored at the next full backup if it is too old.
544 * BackupPC_tarExtract now allows empty archives without reporting
545 an error. Reported by Don Silvia.
547 * Removed Browse Backups link from Nav Bar in Archive Info display.
548 Reported by Ralph PaĂŸgang.
550 * Fixed documentation display for regular users. Reported by Ralph PaĂŸgang.
552 * Status and PC Summary now work for regular users and only show
553 that user's hosts. Server general status information only appears
554 for admins. Suggested by Ralph PaĂŸgang.
556 * Moved the last three navigation-bar links (docs, FAQ and SF) to
557 a new config parameter $Conf{CgiNavBarLinks}. This allows
558 these links to be locally configured. Based on a patch
559 submitted by Ralph PaĂŸgang.
561 * Allow the navigation bar search box to be disabled by
562 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
563 submitted by Ralph PaĂŸgang.
565 * Updates to de.pm from Ralph PaĂŸgang.
567 * Made the BackupPC icon a link to the SF BackupPC project page.
569 #------------------------------------------------------------------------
570 # Version 2.1.0beta1, 4 Apr 2004
571 #------------------------------------------------------------------------
573 * The CSS definition has been removed from the config.pl file and
574 is now a separate file, BackupPC_stnd.css. A new config variable,
575 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
576 Suggested by Ender Mathias.
578 * Fixed the filling of the host name select box for admins.
579 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
580 Reported by Doug Lytle.
582 * Cleaned up warning message for restore using rsync when checksum
583 caching is on, but when file didn't have cached checksums.
585 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
586 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
588 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
589 giving a significant performance improvement. Patch submitted by
592 * Allow several BackupPC_nightly processes to run in parallel based
593 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
594 traversal of the pool, reducing the overall run time for
597 * Allow BackupPC_nightly to split the pool traversal across several
598 nightly runs. This improves the running time per night, at the expense
599 of a slight increase in disk storage as unused pool files might not
600 be deleted for a couple of days. Controller by new config setting
601 $Conf{BackupPCNightlyPeriod}.
603 #------------------------------------------------------------------------
604 # Version 2.1.0beta0, 20 Mar 2004
605 #------------------------------------------------------------------------
607 * A failed full dump is now saved as a partial (incomplete) dump,
608 provided it includes some files. This can be used for browsing,
609 restoring etc, and will also form the basis of resuming full
610 dumps. Only one partial is kept, and it is removed as soon
611 as a successful full (or a new partial) is done.
613 * Added support for resuming a full dump for rsync. The partial
614 full is kept, and to resume an incremental is done against the
615 partial, and a full is done for the rest.
617 * Added support for Rsync checksum caching. Rsync checksum are
618 appended to the compressed pool files. This means that block
619 and file checksums do not need to be recomputed on the server
620 when using rsync. Requires a patch to rsync to support fixed
621 checksum seeds. This patch is included in the cygwin-rsyncd
622 release on http://backuppc.sourceforge.net.
624 * Major addition of Archive feature from Josh Marshall. Special
625 clients can be configured to be archive targets (eg: tape drives,
626 CD-R). Any subset of the backup clients can be selected and tar
627 archives are created, optionally compressed and split and written
628 to the output device. Logs are maintained and are browsable.
630 * Major changes from Ryan Kucera to add style sheets to the CGI
631 interface, allowing easy customization. Added new icons and
632 BackupPC logo. Numerous navigation improvements.
634 * Added directory history display to BackupPC_Admin, allowing the
635 user to quickly see which files changed between backups on a
638 * Added exponential expiry option for full dumps. This allows you
641 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
642 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
643 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
644 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
645 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
647 and so on. This allows you, for example, to keep 4 weekly fulls,
648 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
649 16 weeks, for roughly 1 year of history. This works by deleting
650 every other full as each expiry boundary is crossed. Suggested
653 * Added Italian language translation it.pm from Lorenzo Cappelletti.
655 * Major updates to language files for new features and tags changes.
656 Updated makeDist to do pedantic consistency checking of language
659 * Addition of administration options from Paul Lukins. Initial
660 page allows server to be started/stopped/reloaded. This still
661 needs some i18n work. Currently the server start/stop is
664 * Split BackupPC_Admin into a set of modules, one for each major action.
665 Each action is now a seperate module in lib/BackupPC/CGI.
667 * Allow the blackout period begin/end to span midnight. Adapted
668 from patch submitted by David Smith.
670 * Allow multiple blackout periods, with new config variable
671 $Conf{BlackoutPeriods} that replaces the old variables
672 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
673 $Conf{BlackoutWeekDays}. Based on patch submitted by
676 * Disabled alarms after forks to avoid timeouts in children that
677 do not reset their alarm. Prompted by ideas from James Leu.
679 * Added options for block size, buffer size and share wild-card to
680 BackupPC_tarCreate. Also added negative backup number options
681 that are relative to the last (so -1 is the last), suggested by
682 William McKee and Carl Soderstrom.
684 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
685 the user is more likely to see the error with BackupPC_tarCreate.
686 Reported by Paul Fox.
688 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
689 case it doesn't already exist.
691 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
692 SI Reasoning and Niranjan Ghate.
694 * Changed restore code so that option #1 (direct restore) can be
695 disabled if the restore command is undefined. Disabling direct
696 restore is necessary if the share is read-only. Suggested by
699 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
700 a decimal point or comma for international versions of Samba.
701 Patch submitted by Frank Gard.
703 * Browsing and directory history now sort the files in a
704 case-insensitive manner.
706 * Changed exec() syntax to allow executing commands whose path
709 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
710 is zero or undefined. The protects the existing backups in the
711 case of a bad config.pl file. Suggested by Christian Warden.
713 * Swapped the Server and Hosts sections on the Nav bar. Moved the
714 host search text box to the top of the hosts section. This was
715 done to move the variable-length part of the Nav bar (when all
716 hosts are displayed) to the bottom.
718 * Fixed a bug in tar restore related to how the common prefix path is
719 removed. Now ensure that the common path is at a directory boundary.
720 Reported by Patrick Neuner.
722 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
723 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
725 * Added Suse notes to init.d/README from Bruno Vernay.
727 * Added Apache 2 documentation fix from Michael Tuzi.
729 #------------------------------------------------------------------------
730 # Version 2.0.2, 6 Oct 2003
731 #------------------------------------------------------------------------
733 * Fixed stupid last-minute change in octal size conversion in
736 #-----------------------------------------------------------------------
737 # Version 2.0.1, 5 Oct 2003
738 #------------------------------------------------------------------------
740 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
741 files in BackupPC_tarCreate.
743 * Removed smbclient size repair in BackupPC_tarExtract for files
744 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
745 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
746 extacted using smbclient 2.2.x. If you have problems backing up
747 files whose size is between 2GB and 4GB using smbclient 2.2.x
748 you should upgrade smbclient to 3.0, since it now generates
751 * Replace PingClientPath with PingPath in configure.pl.
753 * Removed -T (taint mode) on binaries installed in configure.pl.
755 * Added support for smbclient from samba version 3.0.0.
757 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
760 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
761 if it is not defined. This allows the CGI interface to work
762 when AdminUsers = '*'. Reported by Quentin Arce.
764 * For SMB, code that detected files with a read-locked region (eg:
765 outlook .pst files), removed them and then tried to link with an
766 earlier version was broken. This code missed a step of mangling
767 the file names. This is now fixed. Reported by Pierre Bourgin.
769 * A backup of a share that has zero files is now considered
770 fatal. This is used to catch miscellaneous Xfer errors that
771 result in no files being backed up. A new config parameter
772 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
773 zero to turn off this check. Suggested by Guillaume Filion.
774 Additional change: this check only applies to a full dump.
776 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
777 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
778 smbclient.) Suggested by Guillaume Filion.
780 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
781 the dump is considered failed.
783 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
784 which just included the '/' directory and nothing below. Now it
785 does just --include '/', which should include everything.
788 * Add hostError to DumpPostUserCmd variable substitutions for both dump
791 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
792 makes BackupPC_dump -v work better.
794 * Don't allow browsing with ".." in directory in case a user tries
795 to trick BackupPC_Admin into displaying directories outside where
798 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
799 fixes large file (>2GB) bugs. Large file bugs reported by Steve
802 #------------------------------------------------------------------------
803 # Version 2.0.0, 14 Jun 2003
804 #------------------------------------------------------------------------
806 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
807 Added "no utf8" to all programs, and added binmode() to relevant
810 #------------------------------------------------------------------------
811 # Version 2.0.0beta3, 1 Jun 2003
812 #------------------------------------------------------------------------
814 * Several improvements to restore: cancel now reports the correct
815 message and cleans up correctly.
817 * Rsync with whitespace and wildcard excludes fixed by replacing
818 argList with argList+ in config.pl plus a fix to Lib.pm for
819 shell escaping array arguments.
821 * Fixed rsync restore for character and block special devices
822 (major and minor device numbers weren't correctly restored).
824 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
826 * (Re)-fixed "Bad command" in log file when restore via tar or zip
827 file download is done.
829 * Added untaint to exec in Lib.pm to avoid tainted errors.
831 * Applied additional tweak to hilight patch from Tim Demarest.
833 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
836 * Don't display RsyncdPasswd when displaying config.pl files.
838 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
839 which increases typical buffering from 4K to 16K-64K. This improves the
842 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
843 then a warning is printed.
845 #------------------------------------------------------------------------
846 # Version 2.0.0beta2, 11 May 2003
847 #------------------------------------------------------------------------
849 * Added German translation, provided by Manfred Herrmann.
851 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
853 * Fixed zip and tar file download from CGI under mod_perl. Reported
854 by Pierre Bourgin and Paul Lukins.
856 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
857 Reported by several users.
859 * Added -v option to BackupPC_dump for verbose output (useful when
860 you run the command manually). Added messages for all exits.
862 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
863 now returns the first IP address that matches the subnet mask.
864 Suggested by Tim Demarest.
866 * Fixed BackupPC::View so the top-level directory is handled correctly.
867 This allows the top-level share/directory to be restored via the
868 CGI interface. Reported by several users.
870 * Fixed RsyncFileIO failures on certain large files by replacing seek()
871 with sysseek(). Reported by Manfred Herrmann.
873 * Added configurable highlighting of PC status in the CGI summary
874 screen; submitted by Tim Demarest.
876 * Fixed command queue CGI display; submitted by Tim Demarest.
878 * BackupPC_trashClean now logs an error if it can't remove all the
879 trash and then goes back to sleep, rather than continually trying.
881 * Moved correct user (uid) check into BackupPC::Lib so that all
882 applications do a user check if $Cong{BackupPCUserVerify} is
883 set. The avoids the risk of manually running BackupPC_dump as
886 * Loss of blackout now applies to "host not found" as well as no ping.
887 Reported by Dale Renton.
889 * "Host not found" is now treated in a similar manner to "no ping".
891 * Added suse-linux init.d script from Leon Letto.
893 * Added Gentoo linux init.d script from Tim Demarest.
895 * Applied additional i18n strings from GFK and the translation team.
897 * Fixed option parsing so that getopts errors are reported and we exit.
899 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
901 #------------------------------------------------------------------------
902 # Version 2.0.0beta1, 30 Mar 2003
903 #------------------------------------------------------------------------
905 * Added Spanish translation es.pm from Javier Gonzalez.
907 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
908 when directories were selected in a certain order.
910 * Fixed BackupPC::PoolWrite so that it can recover when the initial
911 file size is wrong. This is needed since rsync could write a file
912 whose size is different from the initial size returned in the
913 file list when that file is updated while rsync is running.
915 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
916 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
917 helps, but it should be benign. See:
918 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
920 #------------------------------------------------------------------------
921 # Version 2.0.0beta0, 23 Feb 2003
922 #------------------------------------------------------------------------
924 * Support for rsync and rsyncd backup and restore. Changes to
925 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
926 and BackupPC::Xfer::RsyncFileIO.
928 * Added internationalization (i18n) code from Xavier Nicollet,
929 with additions from Guillaume Filion. Voila! BackupPC_Admin
930 now supports English and French, and adding more languages is
931 now easy. New config paramater $Conf{Language} sets the language.
933 * Added optional user-defined pre/post dump/restore commands, allowing
934 things like database shutdown/startup for dumps.
936 * Changed the way hosts are found.
938 * Added $Conf{ClientNameAlias}, which allows the name of the physical
939 client machine to be set. This allows several different backup
940 "hosts" to all refer to the same physical machine, which is
941 convenient if several different types of data need to be backed
942 up, or if different parameters are needed for different parts of
945 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
946 $Conf{NmbLookupCmd} allowing all these commands to be fully
947 configured. Also, all commands can also now be fragments of
950 * Moved all smbclient commands into the config.pl file so the specific
951 arguments can be customized. New config parameters are
952 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
953 $Conf{SmbClientRestoreCmd}.
955 * Added new BackupPC::View module that creates views of backups
956 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
957 and BackupPC_tarCreate to use BackupPC::View. This removes lots
958 of merging and mangling code from the higher-level code.
960 * Added code from Toby Johnson that allows additional users to be
961 specified in the hosts file; these users can also view/start/stop
962 and restore backups for that host. Also added a new config
963 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
964 be listed in the left nav bar for admins.
966 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
967 the maximum number of hardlinks per file in the pool. If a file
968 ever gets to this number of links a new pool file is created to
969 handle additional links.
971 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
972 modules to be loaded.
974 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
975 allow language-specific default messages to be overridden.
977 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
978 files to be represented in the attrib file correctly.
980 * Added support for environment variable BPC_SMB_PASSWD, which is the
981 client's smb password. This overrides the old environment variable
984 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
986 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
987 handle files with trailing spaces.
989 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
990 to ignore multiple signals of the same type.
992 * Added reporting of the largest number of hardlinks in the pool to the
995 * Adding reporting of syntax errors in the per-PC config.pl file.
997 * Updated BackupPC_sendEmail to handle language-specific email messages.
999 * Allow client (host) names to contain spaces. Spaces in host names
1000 need to be escaped via "\" in the hosts file. The user of spaces in
1001 host names is discouraged, but they should work. One feature that
1002 doesn't work with host names that contain spaces is the highlighting
1003 of that name in the log file display in the CGI interface. There are
1004 no plans to fix this.
1006 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
1008 * Fixed all open() calls to use 3 argument form to fix handling of file
1009 names with trailing whitespace. Also fixed CGI interface so these
1010 file names are displayed correctly.
1012 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
1013 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
1014 Reported by Pascal Schelcher. Fixed similar problem reported by
1017 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
1018 suggested by Tim Demarest.
1020 #------------------------------------------------------------------------
1021 # Version 1.5.0, 2 Aug 2002
1022 #------------------------------------------------------------------------
1024 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
1025 option instead of --newer-mtime. Also removed --atime-preserve from
1026 $Conf{TarClientCmd}. This makes the default settings work better
1029 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
1030 so it can correctly warn the user to stop it before upgrading. Reported
1033 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
1034 Reported by Guillaume Filion.
1036 * Added LDAP setup to documentation from David Holland.
1038 * Tar.pm now adds a "." to file paths that start with "/", so that all
1039 tar paths are relative. From Ludovic Drolez.
1041 #------------------------------------------------------------------------
1042 # Version 1.5.0beta0, 30 Jun 2002
1043 #------------------------------------------------------------------------
1045 * A full set of restore options is now supported, including direct
1046 restore via smbclient or tar or downloading a zip or tar file.
1048 * Major additions to CGI script to support better directory navigation,
1049 restore features and mod_perl. Also, file downloads from the CGI
1050 interface now correctly preserve the file name and provide the
1051 correct Content-Type for the most common types of files. Improved
1052 directory navigation was contributed by Ryan Kucera.
1054 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
1055 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
1056 create a zip archive of any portion of a backup.
1058 * Substantial additions to BackupPC_tarCreate to support restore,
1059 including modifying path names, handling hardlinks, fixing
1060 support of old backups without attributes (pre-v1.4.0). Plus
1061 BackupPC_tarCreate is now an offical part of the release.
1062 (Lack of support for hardlinks was reported by John Stanley.)
1064 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
1067 * A unix domain socket is now used for communication between the CGI
1068 interface and BackupPC. The original TCP socket is optional. Sockets
1069 are correctly re-initialized if config.pl is updated with new socket
1072 * For improved security messages over the unix or TCP socket are protected
1073 via an MD5 digest based on a shared secret, a sequence number, a time
1074 stamp and a unique per-connection number.
1076 * Additions to configure.pl to support install of directory navigation
1079 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
1080 were set to a single string or list (in v1.4.0 only the case of
1081 hash worked correctly). Reported by Phillip Bertolus.
1083 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
1084 client always subject to blackout, matching the comments in config.pl.
1085 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
1086 reported by Pascal Schelcher.
1088 * Fixed byte and file totals for tar backups, reported by several users.
1090 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
1091 suggested by Erminio Baranzini.
1093 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
1094 well as shell escaping of tar arguments.
1096 * Fixed entity encoding of 8-bit characters in the CGI interface.
1098 * Added optional CGI headers in $Conf{CgiHeaders} that by default
1099 is set to a no-cache pragma. Suggested by Benno Zuure.
1101 #------------------------------------------------------------------------
1102 # Version 1.4.0, 16 Mar 2002
1103 #------------------------------------------------------------------------
1105 * BackupPC now supports tar (in addition to smb) for extracting host
1106 data. This is the most convenient option for linux/unix hosts.
1107 Tar can be configured to run over ssh, rsh or to backup a local
1108 nfs mount from the host.
1110 * Support for special files, including symbolic links, fifo, character
1111 and block device files has been added, so that all native linux/unix
1112 file types can be correctly backed up when using tar transport.
1113 Special files are all stored as regular files and the type attributes
1114 are used to remember the original file type.
1116 * All unix file attributes are now saved (and pooled when possible).
1117 This includes user and group ownership, permissions, and modification
1118 time. Smbclient also does a reasonable job of emulating unix
1119 permissions (such as mtime), and these attributes get saved too.
1121 * The new default is to not fill incremental dumps. configure.pl
1122 automatically sets $Conf{IncrFill} to 0. The default was 1
1123 (incrementals were filled with hardlinks). Since the CGI
1124 script does filling at browsing time, there is no need to
1125 fill incremental dumps.
1127 * Backup file names are now stored in "mangled" form. Each node of a
1128 path is preceded by "f", and special characters (\n, \r, % and /) are
1129 URI-encoded as "%xx", where xx is the ascii character's hex value. So
1130 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
1131 was done mainly so meta-data could be stored alongside the backup
1132 files without name collisions. In particular, the attributes for the
1133 files in a directory are stored in a file called "attrib", and
1134 mangling avoids file name collisions (I discarded the idea of having
1135 a duplicate directory tree for every backup just to store the
1136 attributes). Other meta-data (eg: rsync checksums) could be stored in
1137 file names preceded by, eg, "c". There are two other benefits to
1138 mangling: the share name might contain "/" (eg: "/home/craig" for tar
1139 transport), and I wanted that represented as a single level in the
1140 storage tree. Secondly, as files are written to NewFileList for later
1141 processing by BackupPC_link, embedded newlines in the file's path
1142 will cause problems which are avoided by mangling.
1144 The CGI script undoes the mangling, so it is invisibe to the user.
1145 Of course, old (unmangled) backups are still supported by the CGI
1148 * Various changes to the CGI interface, BackupPC_Admin:
1150 + Added button that allows users to manually start a full dump in
1151 addition to the existing incremental dump.
1153 + Added display of file attributes when browsing backups.
1155 + Added an optional holdoff time specified by the user when canceling
1156 a backup. BackupPC will not attempt any new backups for at least the
1157 specified time. This holdoff time can be changed whether or not a
1160 + Added supports for file mangling, and correct merging of unfilled
1161 backups from mangled or unmangled (and compressed or uncompressed)
1162 fulls when browsing or restoring.
1164 + Only displays a "Start Incr Backup" button if there are already some
1167 + For DHCP hosts, when a user tries to manually start a backup, add
1168 a check for the netbios name of both the host the request came
1169 from (REMOTE_ADDR) and the last known DHCP address for that host
1170 to see if either address matches the host. If not, an error
1171 message is display. The previous behavior was that only requests
1172 from the client itself succeeded, and requests from other machines
1175 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
1176 is 1.4.0. The first digit is for major new releases, the middle digit
1177 is for significant feature releases and improvements, and the last
1178 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
1179 and 1.03 as 1.0.0, ..., 1.3.0.
1181 * BackupPC and the CGI script BackupPC_Admin now check that the effective
1182 user id is correct to avoid accidentally launching BackupPC as the
1183 wrong user or detecting CGI configuration problems. This behavior
1184 can be turned off using the $Conf{BackupPCUserVerify} option.
1186 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
1187 support generic names for both smb and tar transport methods. The
1188 CGI script checks for old names for backward compatibility.
1190 * Major changed to Backup_dump to support new tar transport. All transport
1191 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
1194 * Added workaround for a bug in Samba's smbclient for files between 2GB
1195 and 4GB. The file size in the tar header is incorrect. This allows
1196 files up to 4GB to work with smbclient, rather than 2GB. To support
1197 files larger than 2GB you must make sure perl is compiled with the
1198 uselargefiles option (use "perl -V | egrep largefiles" to check) and
1199 the pool directory must be on a file system that supports large files.
1201 * Moved the pool writing code into a module BackupPC::PoolWrite. This
1202 allows the clever file pool checking (digest, uncompressing, comparing
1203 etc with minimum disk IO) to be used easily in multiple places (eg: it
1204 is now used for writing attribute files so they can be pooled).
1206 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
1208 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
1209 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
1210 on one user's machine was world writable and perl -T correctly
1211 complained about it.
1213 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
1214 Thanks to Kyle Amon for sending the fix. Decided to move the
1215 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
1216 now configure.pl tries to come up with a sensible default based on
1219 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
1220 share name (eg: C$). Thanks to Jules Agee for this fix. Also
1221 changed the default config.pl so that single quotes are used
1222 everywhere so that people don't get tripped up putting '$' inside
1223 double-quoted strings.
1225 #------------------------------------------------------------------------
1226 # Version 1.03, 9 Dec 2001
1227 #------------------------------------------------------------------------
1229 * BackupPC now has full support for compression. There are now two
1230 pool areas, the original pool for uncompressed files, and cpool for
1231 compressed files. The compression is done by Compress::Zlib.
1232 Compression reduces the pool disk usage by around 40%, although your
1233 mileage may vary. Compression is optional and can also be specified on
1234 a per-PC basis (although this will cost more pool storage since many
1235 backup files will have to be stored in both compressed and
1238 * A new script, BackupPC_compressPool, can be run to compress the entire
1239 pool. This is used once to migrate all the pool data from uncompressed
1240 to compressed on existing installations. Read the documentation
1241 (Installing BackupPC/Compressing an existing pool) before running
1242 BackupPC_compressPool!
1244 Alternatively, compression can simply be turned on and all new backups
1245 will be compressed. Both old (uncompressed) and new (compressed)
1246 backups can be browsed and viewed. Eventually, the old backups will
1247 expire and all the pool data will be compressed. However, until the
1248 old backups expire, this approach could require 60% or more additional
1249 pool storage space to store both uncompressed and compressed versions
1250 of the backup files.
1252 * Significant improvements to the cgi interface, BackupPC_Admin:
1254 - much better layout navigation
1255 - handles compressed backup files and compressed log files
1256 - handles unfilled incremental dumps
1257 - better backup directory browsing navigation
1258 - reports compression statistics
1259 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
1260 - Additional customization with $Conf{CgiHeaderFontType},
1261 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
1262 $Conf{CgiHeaderBgColor}.
1264 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
1265 file and queues the PCs itself. Like config.pl, BackupPC will
1266 re-read the hosts file on each wakeup if its modification time
1267 changes, or upon a SIGHUP. This also makes for better behavior
1268 when adding a host: if you add hosts, simply send a SIGHUP to
1269 BackupPC or wait for the next wakeup.
1271 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
1273 * BackupPC_dump keeps track of compressed file sizes so that compression
1274 statistics can be reported by the cgi interface.
1276 * Aging of old log files now handles compressed log files (.z extension).
1278 * Added configuration option $Conf{IncrFill} to specify whether
1279 incremental dumps should be filled in. Old behavior was that
1280 filling was on. Now it's optional. See config.pl for more
1283 * BackupPC_nightly now cleans and generates statistics for both
1284 the uncompressed pool and compressed pool (cpool).
1286 * Added new utility script BackupPC_zcat that can be used to
1287 uncompresses BackupPC files.
1289 * configure.pl offers various options related to compression,
1290 depending upon whether this is a new install or upgrade,
1291 and whether or not Compress::Zlib is installed.
1293 * configure.pl now makes a backup copy of config.pl before
1294 config.pl is updated.
1296 * added three new fields to the backups file to handle optional
1297 filling and compression stats.
1299 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
1300 on each dhcp host once each night to verify that very old backups are
1301 expired. This ensures that very old backups are expired even if
1302 the dhcp host has not been on the network for a long time.
1304 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
1305 even if compression was off. Thanks to Steve Holmes for reporting
1308 * fixed bug that caused a BackupPC queue to get blocked when a backup
1309 cancel attempt was made during the BackupPC_link phase.

1312 # Version 1.02, 28 Oct 2001.
1313 #------------------------------------------------------------------------
1315 * Added new script BackupPC_tarExtract to extract the smbclient tar
1316 archive. This reduces disk writes by perhaps 90-95% and disk reads by
1317 50%. Previously, tar was used to extract and write everything to disk.
1318 Then BackupPC_dump would read enough of each file to compute the MD5
1319 digest, and then compare the full file with candidate pool files. So
1320 for each 1MB file that matches a single file in the pool, there would
1321 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
1323 BackupPC_tarExtract instead extracts the archive using a 1MB memory
1324 buffer. This allows the MD5 digest to be computed without touching the
1325 disk. Next, any potential pool file compares are done by comparing the
1326 pool file against the incoming tar data in memory, which only requires
1327 the pool file to be read. So for each 1MB file that matches a single
1328 file in the pool, there are now no disk writes, and only 1MB of reads.
1329 BackupPC_tarExtract handles arbitrary size files and repeated
1330 potential pool matches. If the incoming file doesn't match the pool
1331 then it is written to disk (once the pool is mature this happens maybe
1334 * Substantial changes to BackupPC_dump:
1336 + BackupPC_tarExtract is now used in place of tar.
1338 + BackupPC_dump now reads the output from both smbclient and
1339 BackupPC_tarExtract and merges them into SmbLOG.
1341 + Named pipes are no longer used to connect smbclient to tar
1342 (now BackupPC_tarExtract). Regular pipes are used instead.
1343 This avoids the need to system mknod or mkfifo.
1345 + Locked files on the client that can't be read by smbclient
1346 previously were filled with 0x0 bytes by smbclient, meaning
1347 tar extracted a useless file filled with 0x0 bytes. Now,
1348 BackupPC_dump watches the output of smbclient and removes
1349 any files that smbclient couldn't read. This avoids storing
1350 useless files. It tries to replace such files with a hard link
1351 to a previous dump. These actions appear in the log file.
1353 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
1354 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
1355 reading and writing compressed and regular files and provides all the
1356 hooks for compression support in BackupPC (should be supported in next
1357 version). BackupPC::FileIO also does efficient writing of files that
1358 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
1359 helpful when smbclient reads a locked file, and it fills the tar
1360 output with a file of the correct size but all 0x0. Such files will be
1361 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
1362 writes such files efficiently (as sparse files), meaning just a few
1363 blocks of disk space will be needed even if the file is large.
1365 * alive/dead counting for blackout now works correctly for DHCP hosts.
1367 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
1368 killed and restarted with backups running.
1370 * added extra non blocking select() in BackupPC to make sure the socket
1373 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1375 * Updated BackupPC_sendEmail to correctly parse the locked file
1376 error from 2.2.1a smbclient, so that missing Outlook file emails
1377 can be correctly sent.
1379 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1380 hostname read from the hosts file.
1382 * BackupPC_Admin provides general summary when the host name is empty.
1384 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1386 * configure.pl complains if BackupPC is already running, reminding you
1387 to stop it before upgrading.
1389 * updated documentation, and fixed auto-insertion of config.pl into
1390 BackupPC.pod (previously the last config parameter was left out of
