22 #------------------------------------------------------------------------
24 * Added configuration and host CGI editor.
26 * Added rsync hardlink support. Requires latest version of
29 * Decoupled BackupPC_dump from BackupPC_nightly by making
30 asynchronous file linking/delete robust to race conditions.
31 Now only BackupPC_nightly and BackupPC_link are mutually
32 exclusive so only one runs at a time, and BackupPC_dump and
33 BackupPC_restore can run anytime.
35 * Added support for multi-level incrementals. In the style of dump(1),
36 the level of each incremental can be specified. Each incremental
37 backups up everything since the most recent backup of a lower level
38 (fulls are always level 0). Previous behavior was all incrementals
39 were level 1, meaning they backed up everything since the last full
40 (level 0). Default configuration is all incrementals are level 1.
42 * Server file names are now in utf8 and optional conversion
43 to/from client name charsets is done.
45 * Backup metadata is now additionally saved to pc/HOST/nnn/backupInfo,
46 in addition to pc/HOST/backups. In case pc/HOST/backups gets trashed,
47 then a new script BackupPC_fixupBackupSummary can read the per-backup
48 metadata from pc/HOST/nnn/backupInfo and reconstruct the backups file.
49 Roberto Moreno also pointed out an early error in the CVS version.
51 * In conf/config.pl, changed --devices to -D in $Conf{RsyncArgs}
52 and $Conf{RsyncRestoreArgs} to fix "fileListReceive failed" and
53 "Can't open .../f%2f for empty output" errors with rsync 2.6.7+.
54 Fix proposed by Justin Pessa and Vincent Ho, and confirmed by
57 * Added Storage module and Storage::Text which localizes all the
58 text data file reading/writing (eg: backups, restores, archives
59 and config.pl files). Added read verify after all write
60 operations for robustness. Additional backends (eg: SQL)
61 can be added in the future as new subclasses of the Storage
64 * Added Config module, and Config::Meta that contains meta data
65 about configuration parameters.
67 * Added Slackware init.d script from Tony Nelson.
69 * Fixed error reporting when restore/archive fail to write the
70 request file to the client directory.
72 * Applied patch from Marc Prewitt for DumpPreShareCmd and DumpPostShareCmd.
74 * Added checking of exit status of Dump/Restore/Archive Pre/Post UserCmd,
75 requested by Kiko Jover, Matthias Bertschy and others.
77 * Apply patch from Pete Wenzel to add smbClientPath => $Conf{SmbClientPath}
78 to DumpPreUserCmd etc.
80 * Added Portuguese Brazillian pt_br.pm from Reginaldo Ferreira.
82 * Jean-Michel Beuken reported several bugs in configure.pl in CVS 3.0.0.
84 * Old backup email warnings now ignore partials requested by Samuel Bancal
86 * Applied patch to bin/BackupPC_sendEmail from Marc Prewitt that
87 ignores any file starting with "." in the pc directory when
88 it is generating warnings about old/unused files/directories.
90 * Applied patch from Marc Prewitt to fix host queue order.
92 * Applied Lorenzo Cappelletti's it.pm patch.
94 * Applied Wander Winkelhorst's nl.pm patch.
96 * Applied Alberto Marconi's it.pm patch.
98 * Add NT_STATUS_FILE_LOCK_CONFLICT to pst read error check in
99 BackupPC_sendEmail to fix bug reported by Dale Renton.
101 * Added fixup of $ENV{REMOTE_USER} to lib/BackupPC/CGI/Lib.pm in the
102 case of using mod_authz_ldap; patch submitted by Alain Perrier.
104 * Added env LC_ALL=C to $Conf{TarClientCmd} and $Conf{TarClientRestoreCmd}
105 to avoid locale problems, suggested by Ludovic Drolez.
107 * Changed ping output parsing to pick out average rtt time, based
108 on patch from Ron Bickers.
110 * Removed leading "./" and top-level "./" directory from
111 zip archives generated by BackupPC_zipCreate. Reported
112 by Josh (hecktarzuli).
114 * BackupPC_tarCreate and BackupPC_zipCreate now allow "@"
115 in share names. Reported by Robert Waldner.
117 * NT_STATUS_INSUFF_SERVER_RESOURCES is now a fatal error for
118 smbclient transfers, suggested by Brian Shand.
120 * Changed bin/BackupPC_archiveHost to use /bin/csh instead of
121 /bin/sh. That way any errors in the pipeline are reported
122 via the exit status, instead of just the last.
124 * Added $Conf{EMailHeaders} for additional email headers, requested
127 * Made shareName argument regexp checking more general to allow parens.
129 * Added some debian init.d instructions to init.d/README from
132 * Documentation updates from Richard Ames, JP Vossen, Torsten Finke.
134 #------------------------------------------------------------------------
135 # Version 2.1.2pl1, __RELEASEDATE__
136 #------------------------------------------------------------------------
138 * Added patch from Michael (mna.news) to ignore "file is unchanged"
139 message from tar 1.15.x during incremental backups.
141 * Fixed creation of .rsrc directories in bin/BackupPC_tarExtract
142 when used with xtar on MacOS. Reported by Samuel Bancal and
143 Matthew Radey, who helped with debugging.
145 * Fixed bug in BackupPC_tarExtract for files >8GB in size whose
146 lengths are multiples of 256. Reported by Jamie Myers and
147 Marko Tukiainen, who both helped debugging the problem.
149 * Fixed bug in lib/BackupPC/Xfer/RsyncFileIO.pm that caused
150 incorrected deleted attributes to be set in directories
151 where one of the files had an rsync phase 1 retry during
152 an incremental. Reported by Tony Nelson.
154 #------------------------------------------------------------------------
155 # Version 2.1.2, 5 Sep 2005
156 #------------------------------------------------------------------------
158 * Fixed simple but serious bug in bin/BackupPC_tarCreate that prevented
159 hardlinks being saved correctly. Debugged by Michael (mna.news)
160 with several other people.
162 * Fixed serious bug in bin/BackupPC_dump reported/debugged by Dan Niles
163 that can happen when multiple full backups are deleted after
164 $Conf{FullKeepCnt} is changed.
166 * Changed lib/BackupPC/CGI/Lib.pm so that link to "$TopDir/conf/$host.pl"
167 is displayed if it exists. Patch from Andreas Vögele.
169 * Applied daemonize patch to bin/BackupPC from:
170 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=301057
172 * It's now a fatal error if $Conf{CompressLevel} is set, but
173 Compress::Zlib is not found. Before $Conf{CompressLevel} was
174 silently set to 0, which made all the backups uncompressed.
175 That meant the user never knew if they forget to install
176 Compress::Zlib but were expecting compression to be on.
178 * Finally increased $Conf{ClientTimeout} to 72000 (20 hours).
180 * Added sleep 1 in restart() function in init.d/src/gentoo-backuppc,
181 suggested by Jon Hood.
183 * Added $DestDir to the path of the CGI image directory in configure.pl.
184 Patch submitted by Andreas Vögele.
186 * Applied extensive patch to French translation from Frederic Lehobey.
188 * Minor change to Dutch language $Lang{Pool_Stat} from Wander Winkelhorst.
190 * Minor change to French language $Lang{EMailOutlookBackupMesg} and
191 $Lang{EMailOutlookBackupSubj} from Ludovic Gasc.
193 #------------------------------------------------------------------------
194 # Version 2.1.1, 13 Mar 2005
195 #------------------------------------------------------------------------
197 * Fixed bug in top-level restore using rsync XferMethod.
198 BackupPC::View was leaving an extra leading "/" at the start
199 of top-level directories, messing up the FileList sort order.
200 Reported and debugged by Gail Edwards.
202 * Added pathCreate() to BackupPC_tarExtract so that new directories
203 are created. Required for xtar on MacOSX since the virtual resource
204 fork directories (.rsrc) are not explicitly included in the tar
205 archive - just the files below .rsrc are.
207 * Changed $host.$bkupNum.tar$fileExt.* to $host.$bkupNum.tar$fileExt*
208 in $parCmd in bin/BackupPC_archiveHost.
210 * Fixed HostSortCompare() in BackupPC to correctly sort hosts so
211 those with the oldest backups get queued first.
213 * Changed test in BackupPC_sendEmail so that directories/files
214 starting with "." in $TopDir/pc are ignored, rather than
217 * Changed BackupPC_sendEmail to include NT_STATUS_FILE_LOCK_CONFLICT
218 in check for bad outlook files.
220 * Ensure that %Status and %StatusHost are empty if requesting
221 status on hosts in lib/BackupPC/CGI/Lib.pm GetStatusInfo().
222 Fixes problem with new hosts under mod_perl.
224 * Added images/icon-hardlink.gif so that hardlinks show file type icon.
226 #------------------------------------------------------------------------
227 # Version 2.1.0pl1, 15 Aug 2004
228 #------------------------------------------------------------------------
230 * Added fix to nl.pm from Lieven Bridts.
232 * Added patch from Tony Nelson to remove $Info{pid} before BackupPC
233 writes the status and shuts down.
235 * Changed BackupPC_nightly so that it doesn't call find() if the
236 directory doesn't exist. This avoids errors in certain versions
237 of perl. Reported by Bernd Rilling.
239 * Fixed BackupPC::CGI::Lib to correctly re-load config.pl for mod_perl.
240 Reported by Tony Nelson and Jimmy Liang.
242 * Explicitly untaint $In{host} in BackupPC::CGI::Lib to fix problem
243 reported by Thomas Tempé.
245 * Added newline to "...skipping because of user requested delay..."
246 log message in BackupPC_dump. Reported by Wayne Scott.
248 * Added read file size error checking to BackupPC_tarCreate.
249 Reported by Brandon Evans.
251 * Added check in BackupPC::Xfer::RsyncFileIO to ensure that when
252 compression is toggled on/off, a compressed backup doesn't link
253 to an uncompressed pool file (and an uncompressed backup doesn't
254 link to a compressed pool file). Reported by Brandon Evans.
256 * Updated documentation with new dirvish URL and a typo from
259 * Fix to BackupPC_sendEmail so that it correctly sends admin emails
260 for hosts that have failed backups. Reported by Simon Kuhn.
262 #------------------------------------------------------------------------
263 # Version 2.1.0, 20 Jun 2004
264 #------------------------------------------------------------------------
266 * Added Dutch translation from Lieven Bridts, with tweaks from
269 * Added PC-specific config file read in CGI/Archive.pm. Patch
272 * Added non-zero exit code to BackupPC_zcat when uncompress fails.
273 Patch from Pete Wenzel.
275 * Cosmetic changes to PC Summary and Log file language strings from
278 * BackupPC::Lib tries to be more careful when renaming the backups
279 file to backups.old. There have been reports of backups being
280 empty, perhaps when the BackupPC data file system fills up.
281 Now backups is not renamed to backups.old if backups is empty.
283 * BackupPC now closes stderr and stdout before renaming and
284 re-opening the log file.
286 * Pre/post backup/restore/archive commands now correctly set
287 "type" to either incr/full/restore/archive, and now cmdType
288 is the type of Pre/post backup/restore/archive command.
290 * BackupPC_archive correctly terminates archive processes on
293 * Updates to BackupPC_stnd.css with absolute font sizes instead
296 * BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
297 also ensures the full backup is older than the maximum age
298 expected from $Conf{FullPeriod}.
300 #------------------------------------------------------------------------
301 # Version 2.1.0beta2pl1, 30 May 2004
302 #------------------------------------------------------------------------
304 * Fixed bug in rsync checksum caching code in BackupPC::Xfer::RsyncDigest.
306 * BackupPC_zipCreate now ensures the earliest mtime is 1/1/1980,
307 since zip file formats don't support earlier dates. Reported
310 * CGI restore via zip and tar now makes sure stderr is ignored
311 when BackupPC_tarCreate and BackupPC_zipCreate are run.
312 Previously any stderr output would get mixed in the archive,
313 corrupting it. Reported by Dan Niles.
315 #------------------------------------------------------------------------
316 # Version 2.1.0beta2, 23 May 2004
317 #------------------------------------------------------------------------
319 * $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} now apply
320 to every share, rather than just the first, in the case where
321 they are arrays and there are multiple shares. Suggested
324 * On the phase 2 retry pass with rsync, verify the cached checksums
325 if checksum caching is turned on. This will catch the case of
326 cached checksums being incorrectly appended to the compressed
327 pool file. Added new config parameter $Conf{RsyncCsumCacheVerifyProb}
328 so that cached checksums are verified with a selectable probability.
329 Also, increased File::RsyncP version number to 0.51.
331 * configure.pl now supports an optional batch mode. Command-line
332 options are used to specify all the information that configure.pl
333 needs. This is useful for building auto-install packages.
334 Also, configure.pl now includes pod documentation, so you can do
335 "perldoc configure.pl" to see all the command-line options.
336 Suggested, tested and tweaked by Stuart Herbert for possible
339 * At each wakeup, clients are now queued based on how old the most
340 recent backup is. Clients with errors are queued first, with
341 the oldest error times going first. The rest of the clients are
342 queued next, with the clients with the oldest backup going first.
343 Previously the clients were simply queued in alphabetic order.
344 Suggested by Mike Trisko and Tony Nelson.
346 * Added config parameter $Conf{PartialAgeMax} that controls whether
347 partials are saved at all, and if so, whether the partial will be
348 ignored at the next full backup if it is too old.
350 * BackupPC_tarExtract now allows empty archives without reporting
351 an error. Reported by Don Silvia.
353 * Removed Browse Backups link from Nav Bar in Archive Info display.
354 Reported by Ralph Paßgang.
356 * Fixed documentation display for regular users. Reported by Ralph Paßgang.
358 * Status and PC Summary now work for regular users and only show
359 that user's hosts. Server general status information only appears
360 for admins. Suggested by Ralph Paßgang.
362 * Moved the last three navigation-bar links (docs, FAQ and SF) to
363 a new config parameter $Conf{CgiNavBarLinks}. This allows
364 these links to be locally configured. Based on a patch
365 submitted by Ralph Paßgang.
367 * Allow the navigation bar search box to be disabled by
368 setting $Conf{CgiSearchBoxEnable} to 0. Based on a patch
369 submitted by Ralph Paßgang.
371 * Updates to de.pm from Ralph Paßgang.
373 * Made the BackupPC icon a link to the SF BackupPC project page.
375 #------------------------------------------------------------------------
376 # Version 2.1.0beta1, 4 Apr 2004
377 #------------------------------------------------------------------------
379 * The CSS definition has been removed from the config.pl file and
380 is now a separate file, BackupPC_stnd.css. A new config variable,
381 $Conf{CgiCSSFile}, gives the name of the CSS file to use.
382 Suggested by Ender Mathias.
384 * Fixed the filling of the host name select box for admins.
385 The default $Conf{CgiNavBarAdminAllHosts} is now 1.
386 Reported by Doug Lytle.
388 * Cleaned up warning message for restore using rsync when checksum
389 caching is on, but when file didn't have cached checksums.
391 * Fixed BackupPC_archiveHost to support par2 (par2cmdline).
392 Patch submitted by Jaco Bongers and adapted by Josh Marshall.
394 * Improved stat() usage in BackupPC_nightly, plus some other cleanup,
395 giving a significant performance improvement. Patch submitted by
398 * Allow several BackupPC_nightly processes to run in parallel based
399 on new $Conf{BackupPCNightlyJobs} setting. This speeds up the
400 traversal of the pool, reducing the overall run time for
403 * Allow BackupPC_nightly to split the pool traversal across several
404 nightly runs. This improves the running time per night, at the expense
405 of a slight increase in disk storage as unused pool files might not
406 be deleted for a couple of days. Controller by new config setting
407 $Conf{BackupPCNightlyPeriod}.
409 #------------------------------------------------------------------------
410 # Version 2.1.0beta0, 20 Mar 2004
411 #------------------------------------------------------------------------
413 * A failed full dump is now saved as a partial (incomplete) dump,
414 provided it includes some files. This can be used for browsing,
415 restoring etc, and will also form the basis of resuming full
416 dumps. Only one partial is kept, and it is removed as soon
417 as a successful full (or a new partial) is done.
419 * Added support for resuming a full dump for rsync. The partial
420 full is kept, and to resume an incremental is done against the
421 partial, and a full is done for the rest.
423 * Added support for Rsync checksum caching. Rsync checksum are
424 appended to the compressed pool files. This means that block
425 and file checksums do not need to be recomputed on the server
426 when using rsync. Requires a patch to rsync to support fixed
427 checksum seeds. This patch is included in the cygwin-rsyncd
428 release on http://backuppc.sourceforge.net.
430 * Major addition of Archive feature from Josh Marshall. Special
431 clients can be configured to be archive targets (eg: tape drives,
432 CD-R). Any subset of the backup clients can be selected and tar
433 archives are created, optionally compressed and split and written
434 to the output device. Logs are maintained and are browsable.
436 * Major changes from Ryan Kucera to add style sheets to the CGI
437 interface, allowing easy customization. Added new icons and
438 BackupPC logo. Numerous navigation improvements.
440 * Added directory history display to BackupPC_Admin, allowing the
441 user to quickly see which files changed between backups on a
444 * Added exponential expiry option for full dumps. This allows you
447 - how many fulls to keep at intervals of $Conf{FullPeriod}, followed by
448 - how many fulls to keep at intervals of 2 * $Conf{FullPeriod},
449 - how many fulls to keep at intervals of 4 * $Conf{FullPeriod},
450 - how many fulls to keep at intervals of 8 * $Conf{FullPeriod},
451 - how many fulls to keep at intervals of 16 * $Conf{FullPeriod},
453 and so on. This allows you, for example, to keep 4 weekly fulls,
454 followed by 6 fulls every 4 weeks (approx 1 month) and 2 fulls at
455 16 weeks, for roughly 1 year of history. This works by deleting
456 every other full as each expiry boundary is crossed. Suggested
459 * Added Italian language translation it.pm from Lorenzo Cappelletti.
461 * Major updates to language files for new features and tags changes.
462 Updated makeDist to do pedantic consistency checking of language
465 * Addition of administration options from Paul Lukins. Initial
466 page allows server to be started/stopped/reloaded. This still
467 needs some i18n work. Currently the server start/stop is
470 * Split BackupPC_Admin into a set of modules, one for each major action.
471 Each action is now a seperate module in lib/BackupPC/CGI.
473 * Allow the blackout period begin/end to span midnight. Adapted
474 from patch submitted by David Smith.
476 * Allow multiple blackout periods, with new config variable
477 $Conf{BlackoutPeriods} that replaces the old variables
478 $Conf{BlackoutHourBegin}, $Conf{BlackoutHourEnd}, and
479 $Conf{BlackoutWeekDays}. Based on patch submitted by
482 * Disabled alarms after forks to avoid timeouts in children that
483 do not reset their alarm. Prompted by ideas from James Leu.
485 * Added options for block size, buffer size and share wild-card to
486 BackupPC_tarCreate. Also added negative backup number options
487 that are relative to the last (so -1 is the last), suggested by
488 William McKee and Carl Soderstrom.
490 * The "Wrong user" message in BackupPC::Lib now goes to stderr, so that
491 the user is more likely to see the error with BackupPC_tarCreate.
492 Reported by Paul Fox.
494 * Add creation of per-PC directory in BackupPC/CGI/Restore.pm in
495 case it doesn't already exist.
497 * Added -q -x to all ssh commands in conf/config.pl. Suggested by
498 SI Reasoning and Niranjan Ghate.
500 * Changed restore code so that option #1 (direct restore) can be
501 disabled if the restore command is undefined. Disabling direct
502 restore is necessary if the share is read-only. Suggested by
505 * Changed regexp in lib/BackupPC/Smb.pm to allow numbers with both
506 a decimal point or comma for international versions of Samba.
507 Patch submitted by Frank Gard.
509 * Browsing and directory history now sort the files in a
510 case-insensitive manner.
512 * Changed exec() syntax to allow executing commands whose path
515 * BackupPC_dump no longer removes backups if $Conf{FullKeepCnt}
516 is zero or undefined. The protects the existing backups in the
517 case of a bad config.pl file. Suggested by Christian Warden.
519 * Swapped the Server and Hosts sections on the Nav bar. Moved the
520 host search text box to the top of the hosts section. This was
521 done to move the variable-length part of the Nav bar (when all
522 hosts are displayed) to the bottom.
524 * Fixed a bug in tar restore related to how the common prefix path is
525 removed. Now ensure that the common path is at a directory boundary.
526 Reported by Patrick Neuner.
528 * Added --chuid ${USER} to init.d/src/gentoo-backuppc. Suggested by
529 SI Reasoning, Pascal Pochol, Michael Evanoff and others.
531 * Added Suse notes to init.d/README from Bruno Vernay.
533 * Added Apache 2 documentation fix from Michael Tuzi.
535 #------------------------------------------------------------------------
536 # Version 2.0.2, 6 Oct 2003
537 #------------------------------------------------------------------------
539 * Fixed stupid last-minute change in octal size conversion in
542 #-----------------------------------------------------------------------
543 # Version 2.0.1, 5 Oct 2003
544 #------------------------------------------------------------------------
546 * Fixed handling of >= 8GB files in BackupPC_tarExtract and >= 4GB
547 files in BackupPC_tarCreate.
549 * Removed smbclient size repair in BackupPC_tarExtract for files
550 between 2GB and 4GB. This means that BackupPC_tarExtract 2.0.1
551 doesn't behave the same as 2.0.0 for file sizes between 2GB and 4GB
552 extacted using smbclient 2.2.x. If you have problems backing up
553 files whose size is between 2GB and 4GB using smbclient 2.2.x
554 you should upgrade smbclient to 3.0, since it now generates
557 * Replace PingClientPath with PingPath in configure.pl.
559 * Removed -T (taint mode) on binaries installed in configure.pl.
561 * Added support for smbclient from samba version 3.0.0.
563 * Fixed $Conf{HardLinkMax} limit check in BackupPC::Lib; reported
566 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
567 if it is not defined. This allows the CGI interface to work
568 when AdminUsers = '*'. Reported by Quentin Arce.
570 * For SMB, code that detected files with a read-locked region (eg:
571 outlook .pst files), removed them and then tried to link with an
572 earlier version was broken. This code missed a step of mangling
573 the file names. This is now fixed. Reported by Pierre Bourgin.
575 * A backup of a share that has zero files is now considered
576 fatal. This is used to catch miscellaneous Xfer errors that
577 result in no files being backed up. A new config parameter
578 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
579 zero to turn off this check. Suggested by Guillaume Filion.
580 Additional change: this check only applies to a full dump.
582 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
583 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
584 smbclient.) Suggested by Guillaume Filion.
586 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
587 the dump is considered failed.
589 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
590 which just included the '/' directory and nothing below. Now it
591 does just --include '/', which should include everything.
594 * Add hostError to DumpPostUserCmd variable substitutions for both dump
597 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
598 makes BackupPC_dump -v work better.
600 * Don't allow browsing with ".." in directory in case a user tries
601 to trick BackupPC_Admin into displaying directories outside where
604 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
605 fixes large file (>2GB) bugs. Large file bugs reported by Steve
608 #------------------------------------------------------------------------
609 # Version 2.0.0, 14 Jun 2003
610 #------------------------------------------------------------------------
612 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
613 Added "no utf8" to all programs, and added binmode() to relevant
616 #------------------------------------------------------------------------
617 # Version 2.0.0beta3, 1 Jun 2003
618 #------------------------------------------------------------------------
620 * Several improvements to restore: cancel now reports the correct
621 message and cleans up correctly.
623 * Rsync with whitespace and wildcard excludes fixed by replacing
624 argList with argList+ in config.pl plus a fix to Lib.pm for
625 shell escaping array arguments.
627 * Fixed rsync restore for character and block special devices
628 (major and minor device numbers weren't correctly restored).
630 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
632 * (Re)-fixed "Bad command" in log file when restore via tar or zip
633 file download is done.
635 * Added untaint to exec in Lib.pm to avoid tainted errors.
637 * Applied additional tweak to hilight patch from Tim Demarest.
639 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
642 * Don't display RsyncdPasswd when displaying config.pl files.
644 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
645 which increases typical buffering from 4K to 16K-64K. This improves the
648 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
649 then a warning is printed.
651 #------------------------------------------------------------------------
652 # Version 2.0.0beta2, 11 May 2003
653 #------------------------------------------------------------------------
655 * Added German translation, provided by Manfred Herrmann.
657 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
659 * Fixed zip and tar file download from CGI under mod_perl. Reported
660 by Pierre Bourgin and Paul Lukins.
662 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
663 Reported by several users.
665 * Added -v option to BackupPC_dump for verbose output (useful when
666 you run the command manually). Added messages for all exits.
668 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
669 now returns the first IP address that matches the subnet mask.
670 Suggested by Tim Demarest.
672 * Fixed BackupPC::View so the top-level directory is handled correctly.
673 This allows the top-level share/directory to be restored via the
674 CGI interface. Reported by several users.
676 * Fixed RsyncFileIO failures on certain large files by replacing seek()
677 with sysseek(). Reported by Manfred Herrmann.
679 * Added configurable highlighting of PC status in the CGI summary
680 screen; submitted by Tim Demarest.
682 * Fixed command queue CGI display; submitted by Tim Demarest.
684 * BackupPC_trashClean now logs an error if it can't remove all the
685 trash and then goes back to sleep, rather than continually trying.
687 * Moved correct user (uid) check into BackupPC::Lib so that all
688 applications do a user check if $Cong{BackupPCUserVerify} is
689 set. The avoids the risk of manually running BackupPC_dump as
692 * Loss of blackout now applies to "host not found" as well as no ping.
693 Reported by Dale Renton.
695 * "Host not found" is now treated in a similar manner to "no ping".
697 * Added suse-linux init.d script from Leon Letto.
699 * Added Gentoo linux init.d script from Tim Demarest.
701 * Applied additional i18n strings from GFK and the translation team.
703 * Fixed option parsing so that getopts errors are reported and we exit.
705 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
707 #------------------------------------------------------------------------
708 # Version 2.0.0beta1, 30 Mar 2003
709 #------------------------------------------------------------------------
711 * Added Spanish translation es.pm from Javier Gonzalez.
713 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
714 when directories were selected in a certain order.
716 * Fixed BackupPC::PoolWrite so that it can recover when the initial
717 file size is wrong. This is needed since rsync could write a file
718 whose size is different from the initial size returned in the
719 file list when that file is updated while rsync is running.
721 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
722 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
723 helps, but it should be benign. See:
724 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
726 #------------------------------------------------------------------------
727 # Version 2.0.0beta0, 23 Feb 2003
728 #------------------------------------------------------------------------
730 * Support for rsync and rsyncd backup and restore. Changes to
731 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
732 and BackupPC::Xfer::RsyncFileIO.
734 * Added internationalization (i18n) code from Xavier Nicollet,
735 with additions from Guillaume Filion. Voila! BackupPC_Admin
736 now supports English and French, and adding more languages is
737 now easy. New config paramater $Conf{Language} sets the language.
739 * Added optional user-defined pre/post dump/restore commands, allowing
740 things like database shutdown/startup for dumps.
742 * Changed the way hosts are found.
744 * Added $Conf{ClientNameAlias}, which allows the name of the physical
745 client machine to be set. This allows several different backup
746 "hosts" to all refer to the same physical machine, which is
747 convenient if several different types of data need to be backed
748 up, or if different parameters are needed for different parts of
751 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
752 $Conf{NmbLookupCmd} allowing all these commands to be fully
753 configured. Also, all commands can also now be fragments of
756 * Moved all smbclient commands into the config.pl file so the specific
757 arguments can be customized. New config parameters are
758 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
759 $Conf{SmbClientRestoreCmd}.
761 * Added new BackupPC::View module that creates views of backups
762 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
763 and BackupPC_tarCreate to use BackupPC::View. This removes lots
764 of merging and mangling code from the higher-level code.
766 * Added code from Toby Johnson that allows additional users to be
767 specified in the hosts file; these users can also view/start/stop
768 and restore backups for that host. Also added a new config
769 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
770 be listed in the left nav bar for admins.
772 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
773 the maximum number of hardlinks per file in the pool. If a file
774 ever gets to this number of links a new pool file is created to
775 handle additional links.
777 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
778 modules to be loaded.
780 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
781 allow language-specific default messages to be overridden.
783 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
784 files to be represented in the attrib file correctly.
786 * Added support for environment variable BPC_SMB_PASSWD, which is the
787 client's smb password. This overrides the old environment variable
790 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
792 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
793 handle files with trailing spaces.
795 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
796 to ignore multiple signals of the same type.
798 * Added reporting of the largest number of hardlinks in the pool to the
801 * Adding reporting of syntax errors in the per-PC config.pl file.
803 * Updated BackupPC_sendEmail to handle language-specific email messages.
805 * Allow client (host) names to contain spaces. Spaces in host names
806 need to be escaped via "\" in the hosts file. The user of spaces in
807 host names is discouraged, but they should work. One feature that
808 doesn't work with host names that contain spaces is the highlighting
809 of that name in the log file display in the CGI interface. There are
810 no plans to fix this.
812 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
814 * Fixed all open() calls to use 3 argument form to fix handling of file
815 names with trailing whitespace. Also fixed CGI interface so these
816 file names are displayed correctly.
818 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
819 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
820 Reported by Pascal Schelcher. Fixed similar problem reported by
823 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
824 suggested by Tim Demarest.
826 #------------------------------------------------------------------------
827 # Version 1.5.0, 2 Aug 2002
828 #------------------------------------------------------------------------
830 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
831 option instead of --newer-mtime. Also removed --atime-preserve from
832 $Conf{TarClientCmd}. This makes the default settings work better
835 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
836 so it can correctly warn the user to stop it before upgrading. Reported
839 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
840 Reported by Guillaume Filion.
842 * Added LDAP setup to documentation from David Holland.
844 * Tar.pm now adds a "." to file paths that start with "/", so that all
845 tar paths are relative. From Ludovic Drolez.
847 #------------------------------------------------------------------------
848 # Version 1.5.0beta0, 30 Jun 2002
849 #------------------------------------------------------------------------
851 * A full set of restore options is now supported, including direct
852 restore via smbclient or tar or downloading a zip or tar file.
854 * Major additions to CGI script to support better directory navigation,
855 restore features and mod_perl. Also, file downloads from the CGI
856 interface now correctly preserve the file name and provide the
857 correct Content-Type for the most common types of files. Improved
858 directory navigation was contributed by Ryan Kucera.
860 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
861 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
862 create a zip archive of any portion of a backup.
864 * Substantial additions to BackupPC_tarCreate to support restore,
865 including modifying path names, handling hardlinks, fixing
866 support of old backups without attributes (pre-v1.4.0). Plus
867 BackupPC_tarCreate is now an offical part of the release.
868 (Lack of support for hardlinks was reported by John Stanley.)
870 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
873 * A unix domain socket is now used for communication between the CGI
874 interface and BackupPC. The original TCP socket is optional. Sockets
875 are correctly re-initialized if config.pl is updated with new socket
878 * For improved security messages over the unix or TCP socket are protected
879 via an MD5 digest based on a shared secret, a sequence number, a time
880 stamp and a unique per-connection number.
882 * Additions to configure.pl to support install of directory navigation
885 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
886 were set to a single string or list (in v1.4.0 only the case of
887 hash worked correctly). Reported by Phillip Bertolus.
889 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
890 client always subject to blackout, matching the comments in config.pl.
891 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
892 reported by Pascal Schelcher.
894 * Fixed byte and file totals for tar backups, reported by several users.
896 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
897 suggested by Erminio Baranzini.
899 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
900 well as shell escaping of tar arguments.
902 * Fixed entity encoding of 8-bit characters in the CGI interface.
904 * Added optional CGI headers in $Conf{CgiHeaders} that by default
905 is set to a no-cache pragma. Suggested by Benno Zuure.
907 #------------------------------------------------------------------------
908 # Version 1.4.0, 16 Mar 2002
909 #------------------------------------------------------------------------
911 * BackupPC now supports tar (in addition to smb) for extracting host
912 data. This is the most convenient option for linux/unix hosts.
913 Tar can be configured to run over ssh, rsh or to backup a local
914 nfs mount from the host.
916 * Support for special files, including symbolic links, fifo, character
917 and block device files has been added, so that all native linux/unix
918 file types can be correctly backed up when using tar transport.
919 Special files are all stored as regular files and the type attributes
920 are used to remember the original file type.
922 * All unix file attributes are now saved (and pooled when possible).
923 This includes user and group ownership, permissions, and modification
924 time. Smbclient also does a reasonable job of emulating unix
925 permissions (such as mtime), and these attributes get saved too.
927 * The new default is to not fill incremental dumps. configure.pl
928 automatically sets $Conf{IncrFill} to 0. The default was 1
929 (incrementals were filled with hardlinks). Since the CGI
930 script does filling at browsing time, there is no need to
931 fill incremental dumps.
933 * Backup file names are now stored in "mangled" form. Each node of a
934 path is preceded by "f", and special characters (\n, \r, % and /) are
935 URI-encoded as "%xx", where xx is the ascii character's hex value. So
936 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
937 was done mainly so meta-data could be stored alongside the backup
938 files without name collisions. In particular, the attributes for the
939 files in a directory are stored in a file called "attrib", and
940 mangling avoids file name collisions (I discarded the idea of having
941 a duplicate directory tree for every backup just to store the
942 attributes). Other meta-data (eg: rsync checksums) could be stored in
943 file names preceded by, eg, "c". There are two other benefits to
944 mangling: the share name might contain "/" (eg: "/home/craig" for tar
945 transport), and I wanted that represented as a single level in the
946 storage tree. Secondly, as files are written to NewFileList for later
947 processing by BackupPC_link, embedded newlines in the file's path
948 will cause problems which are avoided by mangling.
950 The CGI script undoes the mangling, so it is invisibe to the user.
951 Of course, old (unmangled) backups are still supported by the CGI
954 * Various changes to the CGI interface, BackupPC_Admin:
956 + Added button that allows users to manually start a full dump in
957 addition to the existing incremental dump.
959 + Added display of file attributes when browsing backups.
961 + Added an optional holdoff time specified by the user when canceling
962 a backup. BackupPC will not attempt any new backups for at least the
963 specified time. This holdoff time can be changed whether or not a
966 + Added supports for file mangling, and correct merging of unfilled
967 backups from mangled or unmangled (and compressed or uncompressed)
968 fulls when browsing or restoring.
970 + Only displays a "Start Incr Backup" button if there are already some
973 + For DHCP hosts, when a user tries to manually start a backup, add
974 a check for the netbios name of both the host the request came
975 from (REMOTE_ADDR) and the last known DHCP address for that host
976 to see if either address matches the host. If not, an error
977 message is display. The previous behavior was that only requests
978 from the client itself succeeded, and requests from other machines
981 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
982 is 1.4.0. The first digit is for major new releases, the middle digit
983 is for significant feature releases and improvements, and the last
984 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
985 and 1.03 as 1.0.0, ..., 1.3.0.
987 * BackupPC and the CGI script BackupPC_Admin now check that the effective
988 user id is correct to avoid accidentally launching BackupPC as the
989 wrong user or detecting CGI configuration problems. This behavior
990 can be turned off using the $Conf{BackupPCUserVerify} option.
992 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
993 support generic names for both smb and tar transport methods. The
994 CGI script checks for old names for backward compatibility.
996 * Major changed to Backup_dump to support new tar transport. All transport
997 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
1000 * Added workaround for a bug in Samba's smbclient for files between 2GB
1001 and 4GB. The file size in the tar header is incorrect. This allows
1002 files up to 4GB to work with smbclient, rather than 2GB. To support
1003 files larger than 2GB you must make sure perl is compiled with the
1004 uselargefiles option (use "perl -V | egrep largefiles" to check) and
1005 the pool directory must be on a file system that supports large files.
1007 * Moved the pool writing code into a module BackupPC::PoolWrite. This
1008 allows the clever file pool checking (digest, uncompressing, comparing
1009 etc with minimum disk IO) to be used easily in multiple places (eg: it
1010 is now used for writing attribute files so they can be pooled).
1012 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
1014 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
1015 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
1016 on one user's machine was world writable and perl -T correctly
1017 complained about it.
1019 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
1020 Thanks to Kyle Amon for sending the fix. Decided to move the
1021 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
1022 now configure.pl tries to come up with a sensible default based on
1025 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
1026 share name (eg: C$). Thanks to Jules Agee for this fix. Also
1027 changed the default config.pl so that single quotes are used
1028 everywhere so that people don't get tripped up putting '$' inside
1029 double-quoted strings.
1031 #------------------------------------------------------------------------
1032 # Version 1.03, 9 Dec 2001
1033 #------------------------------------------------------------------------
1035 * BackupPC now has full support for compression. There are now two
1036 pool areas, the original pool for uncompressed files, and cpool for
1037 compressed files. The compression is done by Compress::Zlib.
1038 Compression reduces the pool disk usage by around 40%, although your
1039 mileage may vary. Compression is optional and can also be specified on
1040 a per-PC basis (although this will cost more pool storage since many
1041 backup files will have to be stored in both compressed and
1044 * A new script, BackupPC_compressPool, can be run to compress the entire
1045 pool. This is used once to migrate all the pool data from uncompressed
1046 to compressed on existing installations. Read the documentation
1047 (Installing BackupPC/Compressing an existing pool) before running
1048 BackupPC_compressPool!
1050 Alternatively, compression can simply be turned on and all new backups
1051 will be compressed. Both old (uncompressed) and new (compressed)
1052 backups can be browsed and viewed. Eventually, the old backups will
1053 expire and all the pool data will be compressed. However, until the
1054 old backups expire, this approach could require 60% or more additional
1055 pool storage space to store both uncompressed and compressed versions
1056 of the backup files.
1058 * Significant improvements to the cgi interface, BackupPC_Admin:
1060 - much better layout navigation
1061 - handles compressed backup files and compressed log files
1062 - handles unfilled incremental dumps
1063 - better backup directory browsing navigation
1064 - reports compression statistics
1065 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
1066 - Additional customization with $Conf{CgiHeaderFontType},
1067 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
1068 $Conf{CgiHeaderBgColor}.
1070 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
1071 file and queues the PCs itself. Like config.pl, BackupPC will
1072 re-read the hosts file on each wakeup if its modification time
1073 changes, or upon a SIGHUP. This also makes for better behavior
1074 when adding a host: if you add hosts, simply send a SIGHUP to
1075 BackupPC or wait for the next wakeup.
1077 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
1079 * BackupPC_dump keeps track of compressed file sizes so that compression
1080 statistics can be reported by the cgi interface.
1082 * Aging of old log files now handles compressed log files (.z extension).
1084 * Added configuration option $Conf{IncrFill} to specify whether
1085 incremental dumps should be filled in. Old behavior was that
1086 filling was on. Now it's optional. See config.pl for more
1089 * BackupPC_nightly now cleans and generates statistics for both
1090 the uncompressed pool and compressed pool (cpool).
1092 * Added new utility script BackupPC_zcat that can be used to
1093 uncompresses BackupPC files.
1095 * configure.pl offers various options related to compression,
1096 depending upon whether this is a new install or upgrade,
1097 and whether or not Compress::Zlib is installed.
1099 * configure.pl now makes a backup copy of config.pl before
1100 config.pl is updated.
1102 * added three new fields to the backups file to handle optional
1103 filling and compression stats.
1105 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
1106 on each dhcp host once each night to verify that very old backups are
1107 expired. This ensures that very old backups are expired even if
1108 the dhcp host has not been on the network for a long time.
1110 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
1111 even if compression was off. Thanks to Steve Holmes for reporting
1114 * fixed bug that caused a BackupPC queue to get blocked when a backup
1115 cancel attempt was made during the BackupPC_link phase.
1117 #------------------------------------------------------------------------
1118 # Version 1.02, 28 Oct 2001.
1119 #------------------------------------------------------------------------
1121 * Added new script BackupPC_tarExtract to extract the smbclient tar
1122 archive. This reduces disk writes by perhaps 90-95% and disk reads by
1123 50%. Previously, tar was used to extract and write everything to disk.
1124 Then BackupPC_dump would read enough of each file to compute the MD5
1125 digest, and then compare the full file with candidate pool files. So
1126 for each 1MB file that matches a single file in the pool, there would
1127 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
1129 BackupPC_tarExtract instead extracts the archive using a 1MB memory
1130 buffer. This allows the MD5 digest to be computed without touching the
1131 disk. Next, any potential pool file compares are done by comparing the
1132 pool file against the incoming tar data in memory, which only requires
1133 the pool file to be read. So for each 1MB file that matches a single
1134 file in the pool, there are now no disk writes, and only 1MB of reads.
1135 BackupPC_tarExtract handles arbitrary size files and repeated
1136 potential pool matches. If the incoming file doesn't match the pool
1137 then it is written to disk (once the pool is mature this happens maybe
1140 * Substantial changes to BackupPC_dump:
1142 + BackupPC_tarExtract is now used in place of tar.
1144 + BackupPC_dump now reads the output from both smbclient and
1145 BackupPC_tarExtract and merges them into SmbLOG.
1147 + Named pipes are no longer used to connect smbclient to tar
1148 (now BackupPC_tarExtract). Regular pipes are used instead.
1149 This avoids the need to system mknod or mkfifo.
1151 + Locked files on the client that can't be read by smbclient
1152 previously were filled with 0x0 bytes by smbclient, meaning
1153 tar extracted a useless file filled with 0x0 bytes. Now,
1154 BackupPC_dump watches the output of smbclient and removes
1155 any files that smbclient couldn't read. This avoids storing
1156 useless files. It tries to replace such files with a hard link
1157 to a previous dump. These actions appear in the log file.
1159 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
1160 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
1161 reading and writing compressed and regular files and provides all the
1162 hooks for compression support in BackupPC (should be supported in next
1163 version). BackupPC::FileIO also does efficient writing of files that
1164 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
1165 helpful when smbclient reads a locked file, and it fills the tar
1166 output with a file of the correct size but all 0x0. Such files will be
1167 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
1168 writes such files efficiently (as sparse files), meaning just a few
1169 blocks of disk space will be needed even if the file is large.
1171 * alive/dead counting for blackout now works correctly for DHCP hosts.
1173 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
1174 killed and restarted with backups running.
1176 * added extra non blocking select() in BackupPC to make sure the socket
1179 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
1181 * Updated BackupPC_sendEmail to correctly parse the locked file
1182 error from 2.2.1a smbclient, so that missing Outlook file emails
1183 can be correctly sent.
1185 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
1186 hostname read from the hosts file.
1188 * BackupPC_Admin provides general summary when the host name is empty.
1190 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
1192 * configure.pl complains if BackupPC is already running, reminding you
1193 to stop it before upgrading.
1195 * updated documentation, and fixed auto-insertion of config.pl into
1196 BackupPC.pod (previously the last config parameter was left out of
1199 #------------------------------------------------------------------------
1200 # Version 1.01, 30 Sep 2001
1201 #------------------------------------------------------------------------
1203 * Documentation cleanup in README, doc/BackupPC.pod, conf/config.pl.
