21 # Version __VERSION__, __RELEASEDATE__
22 #------------------------------------------------------------------------
24 * In BackupPC_Admin, default REMOTE_USER to $Conf{BackupPCUser}
25 if it is not defined. This allows the CGI interface to work
26 when AdminUsers = '*'. Reported by Quentin Arce.
28 * For SMB, code that detected files with a read-locked region (eg:
29 outlook .pst files), removed them and then tried to link with an
30 earlier version was broken. This code missed a step of mangling
31 the file names. This is now fixed. Reported by Pierre Bourgin.
33 * A backup of a share that has zero files is now considered
34 fatal. This is used to catch miscellaneous Xfer errors that
35 result in no files being backed up. A new config parameter
36 $Conf{BackupZeroFilesIsFatal} (defaults to 1) and can be set to
37 zero to turn off this check. Suggested by Guillaume Filion.
39 * SMB: now detect NT_STATUS_ACCESS_DENIED on entire share or BackupFilesOnly
40 (also ERRDOS - ERRnoaccess (Access denied.) for older versions of
41 smbclient.) Suggested by Guillaume Filion.
43 * SMB: now detects "tree connect failed: NT_STATUS_BAD_NETWORK_NAME" and
44 the dump is considered failed.
46 * Rsync: Previously BackupFilesOnly = '/' did --include '/' --exclude '/*',
47 which just included the '/' directory and nothing below. Now it
48 does just --include '/', which should include everything.
51 * Add hostError to DumpPostUserCmd variable substitutions for both dump
54 * Verbose output in Lib.pm goes to STDERR, not STDOUT. This now
55 makes BackupPC_dump -v work better.
57 * Don't allow browsing with ".." in directory in case a user tries
58 to trick BackupPC_Admin into displaying directories outside where
61 * Required File::RsyncP version is now 0.44, since File::RsyncP 0.44
62 fixes large file (>2GB) bugs. Large file bugs reported by Steve
65 #------------------------------------------------------------------------
66 # Version 2.0.0, 14 Jun 2003
67 #------------------------------------------------------------------------
69 * Minor tweaks to disable utf8 on utf8-capable machines (eg: RH8+).
70 Added "no utf8" to all programs, and added binmode() to relevant
73 #------------------------------------------------------------------------
74 # Version 2.0.0beta3, 1 Jun 2003
75 #------------------------------------------------------------------------
77 * Several improvements to restore: cancel now reports the correct
78 message and cleans up correctly.
80 * Rsync with whitespace and wildcard excludes fixed by replacing
81 argList with argList+ in config.pl plus a fix to Lib.pm for
82 shell escaping array arguments.
84 * Fixed rsync restore for character and block special devices
85 (major and minor device numbers weren't correctly restored).
87 * Fixed typo in bin/BackupPC_restore (XferLOG -> RestoreLOG).
89 * (Re)-fixed "Bad command" in log file when restore via tar or zip
90 file download is done.
92 * Added untaint to exec in Lib.pm to avoid tainted errors.
94 * Applied additional tweak to hilight patch from Tim Demarest.
96 * $Conf{CgiAdminUsers} = '*' now allows privileged even with REMOTE_USER
99 * Don't display RsyncdPasswd when displaying config.pl files.
101 * Replace pipe with socketpair in bin/BackupPC_dump and bin/BackupPC_restore,
102 which increases typical buffering from 4K to 16K-64K. This improves the
105 * Add check on $ENV{LANG} setting do configure.pl: if LANG includes utf
106 then a warning is printed.
108 #------------------------------------------------------------------------
109 # Version 2.0.0beta2, 11 May 2003
110 #------------------------------------------------------------------------
112 * Added German translation, provided by Manfred Herrmann.
114 * Fixed large-file problem with rsync, reported by Manfred Herrmann.
116 * Fixed zip and tar file download from CGI under mod_perl. Reported
117 by Pierre Bourgin and Paul Lukins.
119 * Fixed directory browsing and top-level directory browsing in 2.0.0beta0.
120 Reported by several users.
122 * Added -v option to BackupPC_dump for verbose output (useful when
123 you run the command manually). Added messages for all exits.
125 * If nmblookup returns multiple IP addresses, NetBiosHostIPFind()
126 now returns the first IP address that matches the subnet mask.
127 Suggested by Tim Demarest.
129 * Fixed BackupPC::View so the top-level directory is handled correctly.
130 This allows the top-level share/directory to be restored via the
131 CGI interface. Reported by several users.
133 * Fixed RsyncFileIO failures on certain large files by replacing seek()
134 with sysseek(). Reported by Manfred Herrmann.
136 * Added configurable highlighting of PC status in the CGI summary
137 screen; submitted by Tim Demarest.
139 * Fixed command queue CGI display; submitted by Tim Demarest.
141 * BackupPC_trashClean now logs an error if it can't remove all the
142 trash and then goes back to sleep, rather than continually trying.
144 * Moved correct user (uid) check into BackupPC::Lib so that all
145 applications do a user check if $Cong{BackupPCUserVerify} is
146 set. The avoids the risk of manually running BackupPC_dump as
149 * Loss of blackout now applies to "host not found" as well as no ping.
150 Reported by Dale Renton.
152 * "Host not found" is now treated in a similar manner to "no ping".
154 * Added suse-linux init.d script from Leon Letto.
156 * Added Gentoo linux init.d script from Tim Demarest.
158 * Applied additional i18n strings from GFK and the translation team.
160 * Fixed option parsing so that getopts errors are reported and we exit.
162 * Changed reporting of Xfer PIDs so that rsync cancel works correctly.
164 #------------------------------------------------------------------------
165 # Version 2.0.0beta1, 30 Mar 2003
166 #------------------------------------------------------------------------
168 * Added Spanish translation es.pm from Javier Gonzalez.
170 * Fixed CGI browse navigation bug that causes BackupPC_Admin to wedge
171 when directories were selected in a certain order.
173 * Fixed BackupPC::PoolWrite so that it can recover when the initial
174 file size is wrong. This is needed since rsync could write a file
175 whose size is different from the initial size returned in the
176 file list when that file is updated while rsync is running.
178 * Added binmode(STDIN) to BackupPC_tarExtract, suggested by Pat LoPresti
179 to fix a problem a RedHat8 with perl 5.8.0. It's unclear why this
180 helps, but it should be benign. See:
181 http://sourceforge.net/mailarchive/forum.php?thread_id=1853018&forum_id=503
183 #------------------------------------------------------------------------
184 # Version 2.0.0beta0, 23 Feb 2003
185 #------------------------------------------------------------------------
187 * Support for rsync and rsyncd backup and restore. Changes to
188 BackupPC_dump, BackupPC_restore, and new modules BackupPC::Xfer::Rsync
189 and BackupPC::Xfer::RsyncFileIO.
191 * Added internationalization (i18n) code from Xavier Nicollet,
192 with additions from Guillaume Filion. Voila! BackupPC_Admin
193 now supports English and French, and adding more languages is
194 now easy. New config paramater $Conf{Language} sets the language.
196 * Added optional user-defined pre/post dump/restore commands, allowing
197 things like database shutdown/startup for dumps.
199 * Changed the way hosts are found.
201 * Added $Conf{ClientNameAlias}, which allows the name of the physical
202 client machine to be set. This allows several different backup
203 "hosts" to all refer to the same physical machine, which is
204 convenient if several different types of data need to be backed
205 up, or if different parameters are needed for different parts of
208 * Replaced $Conf{PingArgs} with $Conf{PingCmd}, added $Conf{DfCmd},
209 $Conf{NmbLookupCmd} allowing all these commands to be fully
210 configured. Also, all commands can also now be fragments of
213 * Moved all smbclient commands into the config.pl file so the specific
214 arguments can be customized. New config parameters are
215 $Conf{SmbClientFullCmd}, $Conf{SmbClientIncrCmd} and
216 $Conf{SmbClientRestoreCmd}.
218 * Added new BackupPC::View module that creates views of backups
219 (handling merging etc). Updated BackupPC_Admin, BackupPC_zipCreate
220 and BackupPC_tarCreate to use BackupPC::View. This removes lots
221 of merging and mangling code from the higher-level code.
223 * Added code from Toby Johnson that allows additional users to be
224 specified in the hosts file; these users can also view/start/stop
225 and restore backups for that host. Also added a new config
226 setting $Conf{CgiNavBarAdminAllHosts} that allows all hosts to
227 be listed in the left nav bar for admins.
229 * Added $Conf{HardLinkMax} (default 31999) which sets the limit on
230 the maximum number of hardlinks per file in the pool. If a file
231 ever gets to this number of links a new pool file is created to
232 handle additional links.
234 * Added $Conf{PerlModuleLoad}, which allows optional additional perl
235 modules to be loaded.
237 * Added $Conf{EMailUserDestDomain} and other EMail config settings to
238 allow language-specific default messages to be overridden.
240 * Added BPC_FTYPE_DELETED to lib/BackupPC/Attrib.pm, allowing deleted
241 files to be represented in the attrib file correctly.
243 * Added support for environment variable BPC_SMB_PASSWD, which is the
244 client's smb password. This overrides the old environment variable
247 * Added taint cleanup for perl5.8 to lib/BackupPC/Lib.pm.
249 * Changed $tar_unpack_header format in BackupPC_tarExtract to correctly
250 handle files with trailing spaces.
252 * Added catching of SIG_PIPE to BackupPC_dump, and changed catch_signal
253 to ignore multiple signals of the same type.
255 * Added reporting of the largest number of hardlinks in the pool to the
258 * Adding reporting of syntax errors in the per-PC config.pl file.
260 * Updated BackupPC_sendEmail to handle language-specific email messages.
262 * Allow client (host) names to contain spaces. Spaces in host names
263 need to be escaped via "\" in the hosts file. The user of spaces in
264 host names is discouraged, but they should work. One feature that
265 doesn't work with host names that contain spaces is the highlighting
266 of that name in the log file display in the CGI interface. There are
267 no plans to fix this.
269 * Renamed $Conf{SmbClientTimeout} to $Conf{ClientTimeout}.
271 * Fixed all open() calls to use 3 argument form to fix handling of file
272 names with trailing whitespace. Also fixed CGI interface so these
273 file names are displayed correctly.
275 * Fixed new 2.0.0 CGI navigation bug that causes the top-level directory
276 to have a URL "&share=//boot&dir=" instead of "&share=/boot&dir=/".
277 Reported by Pascal Schelcher. Fixed similar problem reported by
280 * Added "PerlTaintCheck On" to the mod_perl section in the docs,
281 suggested by Tim Demarest.
283 #------------------------------------------------------------------------
284 # Version 1.5.0, 2 Aug 2002
285 #------------------------------------------------------------------------
287 * Changed conf/config.pl so that $Conf{TarIncrArgs} uses the --newer
288 option instead of --newer-mtime. Also removed --atime-preserve from
289 $Conf{TarClientCmd}. This makes the default settings work better
292 * Fixed configure.pl so it correctly detects a running BackupPC <= v1.4.0
293 so it can correctly warn the user to stop it before upgrading. Reported
296 * Added missing ";" to entity escape in EscapeHTML in BackupPC_Admin.
297 Reported by Guillaume Filion.
299 * Added LDAP setup to documentation from David Holland.
301 * Tar.pm now adds a "." to file paths that start with "/", so that all
302 tar paths are relative. From Ludovic Drolez.
304 #------------------------------------------------------------------------
305 # Version 1.5.0beta0, 30 Jun 2002
306 #------------------------------------------------------------------------
308 * A full set of restore options is now supported, including direct
309 restore via smbclient or tar or downloading a zip or tar file.
311 * Major additions to CGI script to support better directory navigation,
312 restore features and mod_perl. Also, file downloads from the CGI
313 interface now correctly preserve the file name and provide the
314 correct Content-Type for the most common types of files. Improved
315 directory navigation was contributed by Ryan Kucera.
317 * New script BackupPC_zipCreate (contributed by Guillaume Filion) is the
318 zip analog of BackupPC_tarCreate. BackupPC_zipCreate can be used to
319 create a zip archive of any portion of a backup.
321 * Substantial additions to BackupPC_tarCreate to support restore,
322 including modifying path names, handling hardlinks, fixing
323 support of old backups without attributes (pre-v1.4.0). Plus
324 BackupPC_tarCreate is now an offical part of the release.
325 (Lack of support for hardlinks was reported by John Stanley.)
327 * BackupPC_tarExtract now supports hardlinks and fixed pooling of
330 * A unix domain socket is now used for communication between the CGI
331 interface and BackupPC. The original TCP socket is optional. Sockets
332 are correctly re-initialized if config.pl is updated with new socket
335 * For improved security messages over the unix or TCP socket are protected
336 via an MD5 digest based on a shared secret, a sequence number, a time
337 stamp and a unique per-connection number.
339 * Additions to configure.pl to support install of directory navigation
342 * Fixed case where $Conf{BackupFilesOnly} or $Conf{BackupFilesExclude}
343 were set to a single string or list (in v1.4.0 only the case of
344 hash worked correctly). Reported by Phillip Bertolus.
346 * Fixed case of $Conf{BackoutGoodCnt} == 0. This setting now makes the
347 client always subject to blackout, matching the comments in config.pl.
348 Also fixed handling of $Conf{BackoutGoodCnt} < 0 in the CGI script
349 reported by Pascal Schelcher.
351 * Fixed byte and file totals for tar backups, reported by several users.
353 * Fixed --newer-mtime date/timestamp format to make it ISO 8601 compliant,
354 suggested by Erminio Baranzini.
356 * Fixed handling of $Conf{BackupFilesOnly} in BackupPC::Xfer::Tar.pm, as
357 well as shell escaping of tar arguments.
359 * Fixed entity encoding of 8-bit characters in the CGI interface.
361 * Added optional CGI headers in $Conf{CgiHeaders} that by default
362 is set to a no-cache pragma. Suggested by Benno Zuure.
364 #------------------------------------------------------------------------
365 # Version 1.4.0, 16 Mar 2002
366 #------------------------------------------------------------------------
368 * BackupPC now supports tar (in addition to smb) for extracting host
369 data. This is the most convenient option for linux/unix hosts.
370 Tar can be configured to run over ssh, rsh or to backup a local
371 nfs mount from the host.
373 * Support for special files, including symbolic links, fifo, character
374 and block device files has been added, so that all native linux/unix
375 file types can be correctly backed up when using tar transport.
376 Special files are all stored as regular files and the type attributes
377 are used to remember the original file type.
379 * All unix file attributes are now saved (and pooled when possible).
380 This includes user and group ownership, permissions, and modification
381 time. Smbclient also does a reasonable job of emulating unix
382 permissions (such as mtime), and these attributes get saved too.
384 * The new default is to not fill incremental dumps. configure.pl
385 automatically sets $Conf{IncrFill} to 0. The default was 1
386 (incrementals were filled with hardlinks). Since the CGI
387 script does filling at browsing time, there is no need to
388 fill incremental dumps.
390 * Backup file names are now stored in "mangled" form. Each node of a
391 path is preceded by "f", and special characters (\n, \r, % and /) are
392 URI-encoded as "%xx", where xx is the ascii character's hex value. So
393 c:/craig/example.txt is now stored as fc/fcraig/fexample.txt. This
394 was done mainly so meta-data could be stored alongside the backup
395 files without name collisions. In particular, the attributes for the
396 files in a directory are stored in a file called "attrib", and
397 mangling avoids file name collisions (I discarded the idea of having
398 a duplicate directory tree for every backup just to store the
399 attributes). Other meta-data (eg: rsync checksums) could be stored in
400 file names preceded by, eg, "c". There are two other benefits to
401 mangling: the share name might contain "/" (eg: "/home/craig" for tar
402 transport), and I wanted that represented as a single level in the
403 storage tree. Secondly, as files are written to NewFileList for later
404 processing by BackupPC_link, embedded newlines in the file's path
405 will cause problems which are avoided by mangling.
407 The CGI script undoes the mangling, so it is invisibe to the user.
408 Of course, old (unmangled) backups are still supported by the CGI
411 * Various changes to the CGI interface, BackupPC_Admin:
413 + Added button that allows users to manually start a full dump in
414 addition to the existing incremental dump.
416 + Added display of file attributes when browsing backups.
418 + Added an optional holdoff time specified by the user when canceling
419 a backup. BackupPC will not attempt any new backups for at least the
420 specified time. This holdoff time can be changed whether or not a
423 + Added supports for file mangling, and correct merging of unfilled
424 backups from mangled or unmangled (and compressed or uncompressed)
425 fulls when browsing or restoring.
427 + Only displays a "Start Incr Backup" button if there are already some
430 + For DHCP hosts, when a user tries to manually start a backup, add
431 a check for the netbios name of both the host the request came
432 from (REMOTE_ADDR) and the last known DHCP address for that host
433 to see if either address matches the host. If not, an error
434 message is display. The previous behavior was that only requests
435 from the client itself succeeded, and requests from other machines
438 * Changed the version numbering to X.Y.Z, instead of X.0Y. This release
439 is 1.4.0. The first digit is for major new releases, the middle digit
440 is for significant feature releases and improvements, and the last
441 digit is for bug fixes. You should think of the old 1.00, 1.01, 1.02
442 and 1.03 as 1.0.0, ..., 1.3.0.
444 * BackupPC and the CGI script BackupPC_Admin now check that the effective
445 user id is correct to avoid accidentally launching BackupPC as the
446 wrong user or detecting CGI configuration problems. This behavior
447 can be turned off using the $Conf{BackupPCUserVerify} option.
449 * In numerous places changed "Smb" to "Xfer" (eg: log file names) to
450 support generic names for both smb and tar transport methods. The
451 CGI script checks for old names for backward compatibility.
453 * Major changed to Backup_dump to support new tar transport. All transport
454 specific code moved into BackupPC::Xfer::Smb and BackupPC::Xfer::Tar
457 * Added workaround for a bug in Samba's smbclient for files between 2GB
458 and 4GB. The file size in the tar header is incorrect. This allows
459 files up to 4GB to work with smbclient, rather than 2GB. To support
460 files larger than 2GB you must make sure perl is compiled with the
461 uselargefiles option (use "perl -V | egrep largefiles" to check) and
462 the pool directory must be on a file system that supports large files.
464 * Moved the pool writing code into a module BackupPC::PoolWrite. This
465 allows the clever file pool checking (digest, uncompressing, comparing
466 etc with minimum disk IO) to be used easily in multiple places (eg: it
467 is now used for writing attribute files so they can be pooled).
469 * Changed MD5 to Digest::MD5 to avoid use of the depreceated MD5 module.
471 * Shortened default $Conf{MyPath} so that perl's taint mode is more likely
472 to be happy. The old $Conf{MyPath} contained /usr/local/bin, which
473 on one user's machine was world writable and perl -T correctly
476 * Fixed ping command options in Lib.pm so that it works on OpenBSD.
477 Thanks to Kyle Amon for sending the fix. Decided to move the
478 ping options from Lib.pm into config.pl (as $Conf{PingArgs}) and
479 now configure.pl tries to come up with a sensible default based on
482 * Fixed argument checking in BackupPC_tarExtract to allow '$' in the
483 share name (eg: C$). Thanks to Jules Agee for this fix. Also
484 changed the default config.pl so that single quotes are used
485 everywhere so that people don't get tripped up putting '$' inside
486 double-quoted strings.
488 #------------------------------------------------------------------------
489 # Version 1.03, 9 Dec 2001
490 #------------------------------------------------------------------------
492 * BackupPC now has full support for compression. There are now two
493 pool areas, the original pool for uncompressed files, and cpool for
494 compressed files. The compression is done by Compress::Zlib.
495 Compression reduces the pool disk usage by around 40%, although your
496 mileage may vary. Compression is optional and can also be specified on
497 a per-PC basis (although this will cost more pool storage since many
498 backup files will have to be stored in both compressed and
501 * A new script, BackupPC_compressPool, can be run to compress the entire
502 pool. This is used once to migrate all the pool data from uncompressed
503 to compressed on existing installations. Read the documentation
504 (Installing BackupPC/Compressing an existing pool) before running
505 BackupPC_compressPool!
507 Alternatively, compression can simply be turned on and all new backups
508 will be compressed. Both old (uncompressed) and new (compressed)
509 backups can be browsed and viewed. Eventually, the old backups will
510 expire and all the pool data will be compressed. However, until the
511 old backups expire, this approach could require 60% or more additional
512 pool storage space to store both uncompressed and compressed versions
515 * Significant improvements to the cgi interface, BackupPC_Admin:
517 - much better layout navigation
518 - handles compressed backup files and compressed log files
519 - handles unfilled incremental dumps
520 - better backup directory browsing navigation
521 - reports compression statistics
522 - $Conf{CgiDateFormatMMDD} allows you to set date format (MM/DD or DD/MM)
523 - Additional customization with $Conf{CgiHeaderFontType},
524 $Conf{CgiHeaderFontSize}, $Conf{CgiNavBarBgColor}, and
525 $Conf{CgiHeaderBgColor}.
527 * Eliminated BackupPC_queueAll. BackupPC directly reads the hosts
528 file and queues the PCs itself. Like config.pl, BackupPC will
529 re-read the hosts file on each wakeup if its modification time
530 changes, or upon a SIGHUP. This also makes for better behavior
531 when adding a host: if you add hosts, simply send a SIGHUP to
532 BackupPC or wait for the next wakeup.
534 * BackupPC_dump now compresses the SmbLOG file if compression is enabled.
536 * BackupPC_dump keeps track of compressed file sizes so that compression
537 statistics can be reported by the cgi interface.
539 * Aging of old log files now handles compressed log files (.z extension).
541 * Added configuration option $Conf{IncrFill} to specify whether
542 incremental dumps should be filled in. Old behavior was that
543 filling was on. Now it's optional. See config.pl for more
546 * BackupPC_nightly now cleans and generates statistics for both
547 the uncompressed pool and compressed pool (cpool).
549 * Added new utility script BackupPC_zcat that can be used to
550 uncompresses BackupPC files.
552 * configure.pl offers various options related to compression,
553 depending upon whether this is a new install or upgrade,
554 and whether or not Compress::Zlib is installed.
556 * configure.pl now makes a backup copy of config.pl before
557 config.pl is updated.
559 * added three new fields to the backups file to handle optional
560 filling and compression stats.
562 * Added -e option to BackupPC_dump. BackupPC now invokes BackupPC_dump -e
563 on each dhcp host once each night to verify that very old backups are
564 expired. This ensures that very old backups are expired even if
565 the dhcp host has not been on the network for a long time.
567 * fixed bug in BackupPC::FileZIO.pm that required Compress::Zlib,
568 even if compression was off. Thanks to Steve Holmes for reporting
571 * fixed bug that caused a BackupPC queue to get blocked when a backup
572 cancel attempt was made during the BackupPC_link phase.
574 #------------------------------------------------------------------------
575 # Version 1.02, 28 Oct 2001.
576 #------------------------------------------------------------------------
578 * Added new script BackupPC_tarExtract to extract the smbclient tar
579 archive. This reduces disk writes by perhaps 90-95% and disk reads by
580 50%. Previously, tar was used to extract and write everything to disk.
581 Then BackupPC_dump would read enough of each file to compute the MD5
582 digest, and then compare the full file with candidate pool files. So
583 for each 1MB file that matches a single file in the pool, there would
584 be 1MB of disk writes and 2MB of disk reads (to compare two 1MB files).
586 BackupPC_tarExtract instead extracts the archive using a 1MB memory
587 buffer. This allows the MD5 digest to be computed without touching the
588 disk. Next, any potential pool file compares are done by comparing the
589 pool file against the incoming tar data in memory, which only requires
590 the pool file to be read. So for each 1MB file that matches a single
591 file in the pool, there are now no disk writes, and only 1MB of reads.
592 BackupPC_tarExtract handles arbitrary size files and repeated
593 potential pool matches. If the incoming file doesn't match the pool
594 then it is written to disk (once the pool is mature this happens maybe
597 * Substantial changes to BackupPC_dump:
599 + BackupPC_tarExtract is now used in place of tar.
601 + BackupPC_dump now reads the output from both smbclient and
602 BackupPC_tarExtract and merges them into SmbLOG.
604 + Named pipes are no longer used to connect smbclient to tar
605 (now BackupPC_tarExtract). Regular pipes are used instead.
606 This avoids the need to system mknod or mkfifo.
608 + Locked files on the client that can't be read by smbclient
609 previously were filled with 0x0 bytes by smbclient, meaning
610 tar extracted a useless file filled with 0x0 bytes. Now,
611 BackupPC_dump watches the output of smbclient and removes
612 any files that smbclient couldn't read. This avoids storing
613 useless files. It tries to replace such files with a hard link
614 to a previous dump. These actions appear in the log file.
616 * added new module lib/BackupPC/FileZIO.pm. This handles pool file
617 I/O and is used by BackupPC_tarExtract. BackupPC::FileIO supports
618 reading and writing compressed and regular files and provides all the
619 hooks for compression support in BackupPC (should be supported in next
620 version). BackupPC::FileIO also does efficient writing of files that
621 contain leading 0x0 bytes (by seeking past the 0x0 bytes). This is
622 helpful when smbclient reads a locked file, and it fills the tar
623 output with a file of the correct size but all 0x0. Such files will be
624 later removed by BackupPC_dump. But in the meantime, BackupPC::FileIO
625 writes such files efficiently (as sparse files), meaning just a few
626 blocks of disk space will be needed even if the file is large.
628 * alive/dead counting for blackout now works correctly for DHCP hosts.
630 * BackupPC resets activeJob on startup, to fix bug when BackupPC was
631 killed and restarted with backups running.
633 * added extra non blocking select() in BackupPC to make sure the socket
636 * BackupPC avoids queuing multiple BackupPC_queueAll's on the CmdQueue.
638 * Updated BackupPC_sendEmail to correctly parse the locked file
639 error from 2.2.1a smbclient, so that missing Outlook file emails
640 can be correctly sent.
642 * Changed HostInfoRead() in lib/BackupPC/Lib.pm to lowercase the
643 hostname read from the hosts file.
645 * BackupPC_Admin provides general summary when the host name is empty.
647 * configure.pl (and BackupPC) now requires perl 5.6.0 or later.
649 * configure.pl complains if BackupPC is already running, reminding you
650 to stop it before upgrading.
652 * updated documentation, and fixed auto-insertion of config.pl into
653 BackupPC.pod (previously the last config parameter was left out of
