3 Bacula version 2.4.0 Released
4 This is to inform you that we have released the source and Win32 binaries of
5 Bacula version 2.4.0 to the Bacula Source Forge download area.
7 This release consists mainly of a number of bug fixes since 2.2.x
8 but most importantly, a rewrite of significant portions of the
9 Storage daemon reservation and autochanger code. This rewritten
10 code is simpler, more stable, and works much better, particularly
11 with multiple drive autochangers than the prior code did. That
12 said, there are still a number of issues to be resolved. Note,
13 the new code has not been tested in manual volume mount situations.
15 As usual, we strongly recommend when installing to keep the Director and the
16 Storage daemon on the same version. However, since this release only
17 contains refactored code and bug fixes rather than new features, the clients
18 (File daemons) should function perfectly with any 2.2.x version, and there is
19 no database upgrade needed.
21 =====================================================
23 Release Notes for Bacula 2.4.0
25 Bacula code: Total files = 500 Total lines = 188,654 (*.h *.c *.in)
27 This Director and Storage daemon must be upgraded at the same time,
28 but they should be compatible with all 2.0.x File daemons, unless you
29 use some of the new features that affect the FD. In other words, you should
30 not have to upgrade all your File daemons when you upgrade. There is
31 no database upgrade needed from version 2.0.x to 2.2.0 nor from version
32 2.2.x to version 2.4.0
34 ================== Warning !!!!!! ==========================
35 As of Version 2.4.0, the Win32 FD should not descend into
36 any reparse point directory or reparse mount points unless the
37 specified directory is explicitly mentioned at the top level of
38 FileSet (as with Unix). A file that is linked to another file will
39 be backed up, much like Unix hardlinked files. If you want
40 reparse directories backed up, you must explicitly include them
42 ======================================================
44 This release consists mainly of a number of bug fixes since 2.2.x
45 but most importantly, a rewrite of significant portions of the
46 Storage daemon reservation and autochanger code. This rewritten
47 code is simpler, more stable, and works much better, particularly
48 with multiple drive autochangers than the prior code did. That
49 said, there are still a number of issues to be resolved. Note,
50 the new code has not been tested in manual volume mount situations.
53 1095, 1086, 1091, 1070, 1041, 1083, 1078, 1066, 1068, 1038
54 1062, 1065, 1046, 1047, 1031
57 - You can now build bat without the QWT libraries. Use
58 --without-qwt as a ./configure option.
61 - Update version to 2.4.0 to reflect the magnitude of the SD changes.
62 - Make sure to clear JS_WaitMedia when operator mounts a Volume.
64 - Add create_postgresql_database.sql to Win32 installer. Should
65 fix problem reported by Juilio Monteiro.
66 - Get correct slot when auto unloading a device. This fixes bug
68 - Fix possible seg fault if SQL error.
69 - Fix renaming a Volume, which used the wrong Volume name.
70 - If operator has rewind tape, print warning, release tape and
71 try once more. If tape is positioned somewhere, something went
72 wrong, so mark the tape in error and try once more. Previously
73 this error was fatal, now it produces an error message.
74 - Ensure correct volume name displayed during restore
75 - Fix a few more Coverity reported problems.
76 - Fix #1091 about bad output in estimate command.
77 - Modify autochanger locking to attempt to avoid race
79 - Make sure device not busy before doing label command.
80 - Display open() errors except when polling. Previously too
81 many were suppressed. This should fix bug #1070.
82 - Fix Win32 reparse points. Bacula will not recurse into any
83 reparse point directory, including mount points, unless the
84 directory is explicitly mentioned at the top level (same as
85 with Unix). A file that is linked to another file will be
86 backed up -- much as Unix does for hardlinked files.
88 - Remove StorageId test when pruning and recycling (Eric's changes).
89 - Fix buffer overruns detected by Coverity.
90 - Implement --without-qwt
91 - Fix layout of restore tree dialog
92 - Add configure bat QWT libraries, so that bat can be built
93 with or without the QWT libaries.
94 - Implement regression that explicitly tests swapping a Volume
95 from one drive to another.
96 - Enhance disk-changer to detect most error conditions.
97 - Fix SD code so that it properly swaps a Volume between drives.
99 - Prevent a Volume that is being swapped from being freed from
100 the volume list. This will most likely fix, at least partially,
102 - Fix strippath so that it does not get a buffer overrun and crash FD.
103 This fixes bug #1078.
104 - Make inability to change owner/group when creating a dir only a
105 warning rather than an error.
106 - Fix SQL query in migration code
107 - Fix bat seg fault at termination.
108 - Add Bacula generated version to bat about box.
109 - Backport development stream SD reservation system changes.
110 - When wrong volume is mounted during read, unload_autochanger.
111 - Stop searching for Volumes in SD askdir if DIR returns the
112 same volume name twice in a row.
113 - Rework class structures for VOLRES, DCR, and DEVICE to make
114 the method names a bit more logical, and for more logically
115 handling the responsibilities.
116 - Remove redundant code in terminating the scheduler that just
117 causes a seg fault in many cases.
118 - Improve algorithm for detecting pre-reserved volume and
120 - Prevent volume from being released while being swapped.
121 - Refactor parts of stored/mount.c
122 - Add sanity checks for VolWriteTime and VolReadTime
123 - Take care of bad clock changes while computing VolWriteTime
124 and VolReadTime. This should fix or limit #1066
125 - Correct error string numbers in dird/catreq.c
126 - Restructure reserving, acquiring, and mounting volumes. Calls to
127 autochanger are deferred for mount.c -- simplifes the code.
128 - Do not prune any running job. It just fails the job.
129 - Lock the volumes when changing dev->reserved_device and marking
130 the volume unused otherwise the device can get reserved by
131 another job before the volume is released, thus blocking it.
132 - Correct some SD catalog request error messages.
133 - Turn off code in read_record that causes a seg fault in the SD
134 when reading past an EOS_LABEL.
135 - Turn off unloading the autochanger in reserve.c as it just
137 - Lock volumes when unreserving a device.
138 - Do not mark volume unused when recycling.
139 - Fix bug #1068 fixes a SD crash when using Virtual autochanger.
140 - Generate correct JobMedia records during spooling/despooling when
141 running concurrent jobs. Thanks to Tom Ivar Helbekkmo
142 <tih@hamartun.priv.no> for excellent analysis and testing.
143 - *Massive* commit of all fixes and back ports to create 2.2.9
144 Mostly SD reservations enhancements.
145 - Fix Win32 FD backup/restore memory leak due to improper termination
146 of BackupRead/Write. This fixes bug# 1038.
147 - Fixes a StorageId problem with volumes after migration.
148 - Implements autostart scripts for Debian
149 - Fix mtx-changer.in for broken Debian mt program.
150 - Apply doc fix from bug #1062.
151 - Resolve crash and improper restore wx-console Win32 restore
152 GUI. Fixes bug #1065.
153 - Update Win32 wxWidgets to latest version.
154 - Attempt to do correct handling of Win32 mount points. Should
156 - Add const to AIX prototype for initgroups()
157 - Fix to the JobMedia patch, which introduced a new problem.
158 - Fix creating first JobMedia record during Migration to include
159 proper index. This caused slow restores of migrated jobs.
160 - Fix bug #1047, do not strip paths on symbolic links.
161 - Set catalog backup database and user name from values specified on
162 the ./configure line.
163 - Apply patch to correct bug #1031, about wrong pool source information

232 Kern;;;9 Oct 2007;;15:25
233 Bacula version 2.2.5 Released
234 Despite the fact that the Release Notes are rather short, the bug
235 fixes represent quite a lot of work:

240 957, 908, 958, and 955.
241 - It also improves listing performance problems in bat pointed
242 out by Chris Howells.
244 Kern;;;29 Sept 2007;;20:30
245 A serious data loss bug in Bacula version 2.2.4 found and fixed
247 This bug was very elusive and time consuming to track down. It
248 turned out to be a race condition that can lose the last one or
249 two blocks of a Job, which can happen in rare cases only when
250 running multiple simultaneous jobs when a volume fills and one
251 Job finishes receiving the last data from the FD and at the same
252 time a second job detects the end of the Volume. The bug was
253 introduced in version 2.0.0 and did not exist in version 1.38.x.
254 If the bug is triggered, the data is lost (not written to the
255 Volume), and it can occur for any backup job of any level under
256 the conditions noted above.
258 The bug is reported in the bugs database as bug #964, and just
259 this morning I found and tested a fix, which is attached as a patch
260 to the bug report. The patch (2.2.4-lost-block.patch) is also
261 uploaded to the bacula-patches 2.2.x release area. This bug may
262 also be part of the problems reported in bug #935 and possibly
265 Also in the bacula-patches 2.2.x area, you will find other
266 patches that fixes bugs #953, 966, 967, 965, 958, 908, and
267 955. Please refer to bugs.bacula.org for the details.
269 Though this bug quite serious (data loss), it should be rare.
270 However, we recommend everyone to apply the patch.
272 Kern;;;2007/9/14;;;14:30
273 Bacula version 2.2.4 Released
275 This version of Bacula is a minor bug release to version 2.2.3.
276 It contains the following fixes:
278 - Possible fix for authorization problems bug #953.
279 - Possible fix for bug #908.
280 - Add waits to multiple exit detection code to try to force pid
281 file to always be deleted.
282 - Restore good dev.tar.gz to rescue set appropriate binary property.
284 - Fix seg fault in error exit of acquire_for_read after unsuccessfully
285 trying to switch drives by checking for blocking before unblocking.
287 - Cancel storage daemon in all cases where FD reports error. This
288 should fix virtually all cases of bug #920 and will ensure that Devices
289 are released as soon as possible.
290 - Fix error message that was clobbered when Dir tells SD it does not
291 have write permission on Volume. This should fix a minor point
292 in bug #942, but not the main problem.
293 - Fix migration code to get correct Volume name with multiple volumes
294 by skipping |. Fixes bug #936.
295 - Implement patch supplied by Landon to fix bug #944 where using
296 TLS with bconsole uses 99+% of the CPU.
297 - Fix bug #946 about "bacula-dir -t" which doesn't works
299 - Using "m" in bconsole will show messages as in prior versions
300 and not memory usage.
302 - Note, you need GTK >= 2.10 to be able to link the Tray Monitor
305 Kern;;;2007/9/9;;;14:30
306 I regret to announce that there is a rather serious bug in Bacula.
308 Bacula bug #935 reports that during a restore, a large number of files are
309 missing and thus not restored. This is really quite surprising because we
310 have a fairly extensive regression test suite that explicitly tests for this
311 kind of problem many times.
313 Despite our testing, there is indeed a bug in Bacula that has the following
316 1. It happens only when multiple simultaneous Jobs are run (regardless of
317 whether or not data spooling is enabled), and happens only when the
318 Storage daemon is changing from one Volume to another -- i.e. the
319 backups span multiple volumes, and it only happens for Jobs writing
322 2. It has only been observed on disk based backup, but not on tape.
324 3. Under the right circumstances (timing), it could and probably does happen
327 4. It seems to be timing dependent, and requires multiple clients to
328 reproduce, although under the right circumstances, it should be reproducible
329 with a single client doing multiple simultaneous backups.
331 5. Analysis indicates that it happens most often when the clients are slow
332 (e.g. doing Incremental backups).
334 6. It has been verified to exist in versions 2.0.x and 2.2.x.
336 7. It should also be in version 1.38, but could not be reproduced in testing,
337 perhaps due to timing considerations or the fact that the test FD daemons
340 8. The data is correctly stored on the Volume, but incorrect index (JobMedia)
341 records are stored in the database. (the JobMedia record generated during
342 the Volume change contains the index of the new Volume rather than the
343 previous Volume). This will be described in more detail below.
345 9. You can prevent the problem from occurring by either turning off multiple
346 simultaneous Jobs or by ensuring that while running multiple simultaneous
347 Jobs that those Jobs do not span Volumes. E.g. you could manually mark
348 Volumes as full when they are sufficiently large.
350 10. If you are not running multiple simultaneous Jobs, you will not be
351 affected by this bug.
353 11. If you are running multiple simultaneous Jobs to tapes, I believe there is
354 a reasonable probability that this problem could show up when Jobs are split
357 12. If you are running multiple simultaneous Jobs to disks, I believe there is
358 a high probability that this problem will show up when Jobs are split across
361 13. The bug concerns only the Storage daemon so there is no need to update
362 the clients, though I do recommend updating the Director when installing
363 an updated Storage daemon.
365 I have uploaded patches to bug #935 (bugs.bacula.org) that will correct
366 version 2.2.0, 2.2.1, and 2.2.2. The patch has been tested only on version
367 2.2.2 and passes all regression tests as well as the specific test that
368 reproduced the problem.
370 The patch has now been confirmed to fix the problem reported, and Bacula
371 version 2.2.3 has been released to Source Forge.
373 For the technical details of the bug, please see:
375 http://www.bacula.org/downloads/bug-935.txt
379 Kern;;;2007/8/11;;;14:30
381 Bacula Version 2.2.0 has been released to Source Forge.
383 Release Notes for Bacula 2.2.0
385 Bacula code: Total files = 520 Total lines = 195,550 (*.h *.c *.in)
386 82 new files, 41,221 new lines of code, 208,380 lines of change from 2.0.3
388 This Director and Storage daemon must be upgraded at the same time,
389 but they should be compatible with all 2.0.x File daemons, unless you
390 use some of the new features that affect the FD. In other words, you should
391 not have to upgrade all your File daemons when you upgrade. There is
392 no database upgrade needed from version 2.0.x to 2.2.0.
394 Areas requiring caution or testing:
395 - You must have the thread safe version of MySQL client libraries loaded
396 to build with MySQL enabled.
397 - Volumes are pruned only when absolutely necessary -- this may cause
398 your database to grow compared to prior Bacula versions.
399 - Solaris door and even port files are no longer restored (equivalent
400 to what we do with sockets).
401 - SQLite is no longer supported for Solaris -- it fails too often with
402 bus errors. SQLite3 should work on Solaris.
403 - The default setting for SQLite3 is now 'PRAGMA synchronous=OFF'.
404 This makes it run 30 times faster, but increases the possiblity
405 of a corrupted database if your server shuts down unexpectedly.
406 The default behavior can be changed in src/version.h
407 - Restore on Win32, and in particular on Vista is untested. Please
408 test before relying on it. It should backup and restore reparse
410 - Win32 servers are untested, and very likely not to work.
412 The major new features are:
413 - Much faster insertion of attributes (somewhere around 10 times),
414 many thanks to Eric Bollengier and Marc Cousin.
415 - First release of bat (Bacula Administration Tool). Note to build
416 bat you must explicitly enable it on the ./configure line, you
417 must have the Qt4 version 4.2 or later libraries loaded, the qwt
418 (Qt Graphics) package loaded, and qmake and the other Qt4 tools
419 must be available. Most of the implementation was done by Dirk Bartley.
420 - Red/Black restore in memory tree (500 times faster loading).
421 - The Regex Where code to allow easier relocation of restored files
423 - Socket level heartbeat for all connections (untested).
424 - posix_fadvise() use in the FD to improve performance reduces
425 swapping due to opening/reading lots of files. Win32 equivalent
427 - Much improved Volume reservation code that should eliminate most
428 conflicts experienced in multiple drive autochangers.
429 - Simpler locking in the SD in the reservation system.
430 - Detection of file size/date change during backup if enabled.
431 - New Recycle Pool feature -- thanks to Eric.
432 - Efficient implementation of very large include/exclude lists.
433 - Volumes are no longer pruned during 'status dir'
434 - Pruning is now more efficient, and if a Volume is purged,
435 during pruning, it is immediately discovered.
436 - License is now GPL v2 without modifications, fix a few copyright
437 mistakes made when adding FSFE copyright notice.
439 New ./configure options:
440 - --enable-bwx-console
445 - --enable-batch-insert
447 New bconsole commands:
453 - .pwd (in restore tree)
454 - restoreclient (keyword)
455 - backupclient (keyword)
456 - regexwhere (keyword)
457 - update jobid (new command)
458 - recyclepool (keyword)
461 - Heartbeat Interval (bconsole.conf)
462 - Heartbeat Interval (bacula-dir.conf in Director, Client, Storage)
463 - TLS Allowed CN (bacula-dir.conf in Client)
464 - Regex Where (bacula-dir.conf in Job)
465 - Strip Prefix (bacula-dir.conf in Job)
466 - Add Prefix (bacula-dir.conf in Job)
467 - Add Suffex (bacula-dir.conf in Job)
468 - Recycle Pool (bacula-dir.conf in Pool)
469 - FailJobOnError (bacula-dir.conf in RunScript)
470 - CheckFileChanges (bacula-dir.conf in FileSet)
471 - StripPath (bacula-dir.conf in FileSet)
473 Other features or bug fixes:
474 - Fixed bugs: 916, 910, 917, 914, 906, 907,
475 842, 830, 893, 861, 888, 886, 807, 877, 872
476 885, 887, 864, 874, 882, 881, 863, 859,
477 856, 854, 845, 847, 846, 809, 772,
478 822, 825, 824, 808, 802, 797, 798, 795, 789, 791,
479 788, 780, 763, 782, 612, 767, 775, 621, 772, 764,
480 766, 621, 761, 755, 750, 741, 747, 742, 744, and 743.
481 - Configure bat with --enable-bat. Define qwt libraries with
482 --with-qwt=<dir>. See Installation chapter of manual for details.
483 - Create a depkgs-qt package that has both Qt4 and qwt, which are
484 needed to build bat. Most modern Linux systems will have both
485 these packages in the distro.
486 - Storage overrides delete all previous storage definitions instead
488 - One should be able to mount and unmount removable devices if the
489 Device resource has Removeable Media set and the mount and unmount
490 directives are defined.
491 - ./configure will do a better job of searching for qwt libraries.
492 - The Win32 version can no longer be shutdown from the tray monitor.
493 Use the command line or the Services panne.
494 - Keep prune_volumes() from pruning the whole Scratch pool.
495 - More debug output in status storage.
496 - Correct moving a Scratch volume from pool to pool (some
497 critical columns were lost).
498 - Different locking in reservations and despooling systems,
499 which means more micro-locking and less macro-locking, which
500 should give a lot more concurrency at the expense of slightly
501 (<0.1%) more overhead due to more locking/unlocking, but
502 concurrent jobs should run much faster.
503 - Additional drive reservation algorithm that should solve a lot of
504 the problems experienced with multiple drive autochangers.
505 - Storage daemon status command enhanced to more clearly show Volume,
506 pool and media type when a job is waiting.
507 - Made bsmtp work with more strict SMTP servers.
508 - Detect doubly freed buffers in smartall.c
509 - wx-console renamed to bwx-console (Fedora request)
510 - gnome-console renamed to bgnome-console (Fedora request)
511 - Migration preserves original job's FileSetId
512 - Spooling implemented for migration jobs.
513 - Config files can be read through a pipe, by specifying a leading |
514 in front of the configuration path/filename.
515 - New memory command (bconsole) that will print the current Director's
516 memory usage, and an in use buffer dump.
517 - Console name changed from *Console* to -Console- to accomodate Win32
518 filename restrictions.
519 - Corrected the Win32 ftruncate bug.
520 - Additional version information added to Job reports.
521 - New -8 option for bsmtp to specify UTF-8 encoding type.
522 - bsmtp will no longer add < > to target (from, to, cc) if there
523 is already a < in the target.
524 - Prefer Mounted Volumes extended to mean a volume that is being
525 mounted by another job.
526 - Runscript timing set to same as version 1.38.11
527 - New TLS Allowed CN directive(s) permitted.
528 - New bconsole 'exec' command to run external script/command.
529 - Turn on FreeBSD/OpenBSD code to set EOT model on tape.
530 - Drop from root done before database is opened.
531 - Database user and name can be configured with:
532 --with-db-name=name --with-db-user=user
533 - Turn on wait_for_drive in mtx-changer script.
534 - Rework how bar codes are handled in mtx-changer script.
535 This appears to have been an unreported bug.
536 - Updated nagios plugin supplied by Christian Masopust
537 - Better restricted console ACL checking.
538 - New Client Connect Wait directive in Storage daemon so that
539 users can configure how long SD waits for FD connection.
540 - Bacula will no longer permit pruning of the currently running
541 job (note, if other jobs are running, they may be pruned).
542 - Sockets are no longer restored.
543 - dbcheck works in 300K chunks so will typically run faster.
544 - Include/Exclude lists can now be efficiently handled for quite
545 large sizes -- tens of thousands of entries.
546 - Several memory leaks in migration and database usage were fixed.
547 - New console keyword restoreclient, which specifies the client to
548 which the restore will be sent. The client keyword specifies
549 the backup client. The restoreclient keyword is optional if it is
550 not specified, the backup client will also be the restore client.
551 - The disk file size is now checked to ensure that it agrees with the
552 catalog value before Bacula will append to the disk (same as tape

559 Bacula Version 2.0.1 has been released to Source Forge.
560 This is bug fix update to version 2.0.0 and contains
563 - Fix Bacula->Documentation link on Win32 to point to index.html
564 instead of bacula.html. Fixed bug #750.
565 - Return JobId in db_get_job_record() when JobId==0. This should
567 - Do not release source pointers when restarting a failed job.
568 - Add dynamic dll entry point for SHGetFolderPath to Win32 code.
569 This *should* fix bug #747.
570 - Modify winbacula.nsi to substitute with g bin_dir_cmd. Should fix
572 - Modify USTORE constructor to set an empty store_source string,
573 and don't copy the store_source string in a cancel. Hopefully
574 this will fix Arno's seg fault, bug #744.
575 - Add back code to disable conio in configure. Fixes bug #743.
576 - Correct the Options scanner in the FD to correctly handle
577 SHA1 option, which was eating the next option. Reported by
579 - Add code to indicate when the SD is spooling, spool wait, and
580 despooling as requested by Alan Brown.

600 Release Notes for Bacula 2.0.0
602 Bacula code: Total files = 438 Total lines = 154,329 (*.h *.c *.in)
604 ==== IMPORTANT Catalog update required =====
605 - The database format has been updated from what was used in
606 Bacula 1.38.x. You must manually update your database before
607 running Bacula 1.39.x or higher. If you are using Bacula supplied
608 RPMs this is not necessary as the RPM does it automatically.
609 Please backup your previous version of the database before
610 running the update. The update script will be automatically
611 installed in your scripts directory, or can also be found in
612 <bacula-source>/src/cats. It is called:
614 ./update_bacula_tables
616 It is necessary to run it only once the first time you move to
617 a 2.0.0. Upgrading the Bacula version thereafter does not
618 require updating the database again. Depending on the size of
619 your database the script make take a bit of time, to run, but
620 in general, it should be very fast.
622 ==== IMPORTANT new Win32 install procedure =====
623 For Win32 migrations from versions prior to 1.39.0 nothing special
624 needs to be done to upgrade. Everything should be taken care of
625 automatically. The only thing not done is to delete the old C:\bacula
626 directory mostly out of paranoia.
628 ==== IMPORTANT miscellaneous ====
629 - The Gnome console program (gconsole) no longer functions as it
630 should.More importantly, in restore mode, the restore tree is
631 no longer shown in the left pane. I suspect this is due to
632 incompatible changes in the GTK+ API, and hence have given up
633 on gnome and gtk+, as this has already happened several times
634 previously. At some point there will be a new GUI console.
635 - The bacula-dir.conf directive Accept Any Volume has been
636 removed because it was never implemented. You must delete all
637 occurrence of this directive for the Director to run. The Storage
638 daemon will automatically accept any valid Volume that you mount.
639 - The --mandir ./configure option now points to the top level man
640 directory. The man files will be installed under mandir/man8 and
641 mandir/man1 as appropriate.
642 - You *should* be able to use 1.38.x FDs with version 2.0.0 Director
643 and SD providing you do not use any of the new features (runscript,
644 data encryption). It seems to work here, but we do not guarantee it.
645 - Your Director and SD must be simultaneously upgraded.
646 - The restore command no longer uses the MediaType as the primary method
647 of finding a suitable Storage device. Normally it will select the last
648 device used to write a Volume. If no storage device is defined, it
649 will use the old algorithm which selects the first Storage resource
650 with the correct MediaType.
651 - The MD5/SHA1 hash codes kept in the database are now kept in a binary
652 format compatible with the rest of the world. If you are running verify
653 jobs, you *must* do an InitCatalog or all files will show an MD5
654 difference. Also, authentication uses the new algorithm by
655 default, but *should* accept connections from older components (FD) using
656 the old non-compatible algorithm. This has been tested, but more
657 more testing is still needed.
658 - A stock SuSE 10.1 kernel may crash when Bacula runs and accesses
659 the tape drive. Workaround, load the SuSE 10.1 version 2.6.16.21-0.25
660 kernel or later. The SuSE 10.2 Alpha 5 or later kernel also works.
661 This problem may also be present in certain Fedora FC5 kernels.
662 - If you have been using the data encryption feature of 1.39.x, please
663 be aware that certain combinations of encryption and other options
664 with version 1.39.0 through 1.39.26 created Volume data that cannot
665 be restored. We strongly recommend that anyone using encryption
666 carefully review his/her backups and at a minium do a Full backup
667 with 1.39.28 of all encrypted data. Robert Nelson has identified
668 and fixed it as follows:
670 No filters = Works fine
672 Compression = Works fine
673 Encryption = Works fine
674 Sparse + Compression = Works fine
676 Sparse + Encryption = Restore broken
677 Sparse + Compression + Encryption = Restore broken
678 Compression + Encryption = Restore broken
681 Most combinations work, but some encrypted files are
682 not properly restored.
685 All combinations work fine except Sparse+Encryption.
687 Bottom line, if you are using data encryption, please test restoring
688 data to be sure it all works correctly.
689 - The current Volume format written by 1.39.22 is different from
690 the format written by previous versions. The two formats
691 are not compatible. Thus any DVDs written prior to 1.39.22 will
692 be unreadable by version 1.39.22.
693 - If you previously run a Bacula version prior to 1.39.30, the JobMedia
694 data may not be correct for disk Volumes. This can cause incorrect
695 seeking in versions after 1.39.30. If you experience what appears to
696 be data I/O or integrity errors during restores, please add the
697 following directive to your disk DEVICE resource in the Storage
700 Block Positioning = no
702 This will turn off all seek requests during restores and avoid
704 - VSS for Windows clients is now enabled by default.
705 - Do not unload autochanger when doing "update slots"
706 - Implement mount command for autochanger, see manual.
708 New Features in 2.0.0:
709 - Turn on disk seek code for restores.
710 - There is a partial but reasonable translation of the Bacula
711 messages for French. To install it, first configure and build
712 Bacula, then as root run:
714 cd <bacula-source>/po
717 If you have your locale set properly you will get the translated
719 - Bacula now support Migration jobs that are documented in a new
720 Migration chapter in the manual
721 http://www.bacula.org/dev-manual/Migration.html
722 - Data encryption is now implemented and is documented in
723 a new chapter of the manual at:
724 http://www.bacula.org/dev-manual/Bacula_Data_Encryption.html
725 - Additional support for removable devices. See the
726 Requires Mount, Mount Point, Mount Command, and Unmount
727 Commands in the Storage daemon configuration chapter:
728 http://www.bacula.org/dev-manual/Storage_Daemon_Configuratio.html
729 Also see the Edit Codes for Mount and Unmount Directives in the
731 - Switch the Win32 build from using Microsoft C++ to using mingw32
732 cross-compiling. The initial work was done by Howard Thomson,
733 then tweaked by me. Robert Nelson then totally reworked the
734 cross-compiling code so that it not only cross-compiles, but
735 also compiles on Visual Studio, and at the same time, he added
736 all the current Unix features to the FD, such as selection on
737 drives, encryption support, building *all* the tools, ...
738 - The Director and Storage daemon have now been ported to Win32.
739 This code is working but should still be tested carefully
740 before putting into production.
741 - Bacula restore and bextract can now extract non-portable Win32 data to
742 any client (including Unix/Linux clients). Of course, in doing so,
743 the Microsoft specific permissions and ACLs will be lost. Thanks
744 to Thorsten Engel for this code.
745 - The 260 character limitation for Win32 paths name lengths is now
746 eliminated thanks to Thorsten Engel. However, if you are using
747 Volume Shadow Copy, please be careful to specify all the paths
748 in the bacula-fd.conf file using a full path notation including
750 - Eric Bollengier wrote new RunScript directives that includes
751 the old RunBefore/AfterJob and ClientRunBefore/AfterJob features
752 plus a *lot* more, allowing you to control just about every aspect
753 of running scripts. See the manual for detailed documentation.
754 http://www.bacula.org/dev-manual/Configuring_Director.html#5227
755 - SunOS ACLs should now work thanks to a patch from David Duchscher.
756 - Apply days keyword patch from Alexander.Bergolth at wu-wien.ac.at
757 If this patch is applied, the number of days can be specified with
758 "list nextvol days=xx"
761 This can be used to preview the next scheduled job (and the
762 next tape to be used) on Fridays if there are no scheduled jobs during
764 - From Eric Bollengier. One can now using the bconsole wait command do:
765 wait (wait for all jobs to stop)
767 wait jobuid=unique id
769 - Volumes can now be set to Enable, Disable, or Archive. If they
770 are not enabled, Volumes will not be mounted.
771 Implement update volume enable=(on|off|true|false|archived|0|1|2)
772 - Add Catalog message destination in Messages resource that puts the
773 job report in the Log database table.
774 - Writing/reading DVD Volumes is much more stable -- to the point
775 of being useful. Thanks to Richard Mortimer.
776 - Add enable/disable job=<job-name>. This command prevents
777 the specified job from being scheduled. Even when disabled,
778 the job can be manually started from the console.
779 - The database Id records should be 32/64 bit independent now. 64 bits
780 can be enabled by changing one define and changing the appropriate
781 table variable. Normally, you need 64 bits only for FileId.
782 - Relative path specifications (i.e. ../xxx) are now permitted in
783 the restore cd command.
784 - When running multiple simultaneous jobs, most jobs that use spooling
785 will now finish faster due to a mutex optimization made by Eric
787 - Conf files containing UTF-8 marker at the head of the file as well as
788 conf files containing Window cr/lf and Mac cr line termination characters
789 are now accepted thanks to Robert Nelson.
790 - Windows tray status windows are scrollable and resizable.
791 - Win32 external script execution is much more flexible -- handles
792 spaces in names better, ...
793 - Lots of DVD fixes -- writing DVDs is now reported to work.
794 - Fix opening of database in a restricted console to respect
796 - Much better automatic handling of multiple database catalogs in
798 - Permit multiple console/director resources in bconsole.conf.
799 patch from Carsten Paeth calle@calle.in-berlin.de
800 - Character substitution in Job/JobDefs WriteBootStrap.
801 from Eric Bollengier.
802 - Apply patch supplied in bug #656 to pass priority field
803 in the run dialog to the Director in gnome console.
804 - Add support of encrypted data stream to bscan from Eric.
805 display data_len instead of data content (may be binary).
806 - Add Enabled=xxx on update slots command.
807 - Add host:port to connect failure messages to FD and SD from Dir/
808 - Add WhereACL to console ACL list. If nothing is specified, only
809 the default is permitted for restore. Otherwise, *all* allows any
810 path, or you can specify permitted paths. This should allow control
811 over where users can restore files. This is untested.
812 - Install man pages with 'make install'.
813 - Add Media.Enabled flag to client backups for dotcmds.c
814 - Enforce Media.Enabled=1 for a current restore to work
815 - Require restore case 3 to have sqlquery permission to work.
816 - Add -n option to bconsole to turn off conio -- used in bweb.
817 - The bytes field in the terminated jobs part of the status
818 command now reports in KB, MB, ... units.
819 - When not descending into a directory, print the File= name that
820 triggered it -- makes why not descending a bit clearer
821 - Do not unload autochanger when doing "update slots"
822 - Implement mount command for autochanger
823 - Fix bug #462 incorrect error message printed when client script called
824 from File= was not found.
825 - Fix bug #558 (waiting for feedback) where Bacula needs too much time to
826 do a rewind on Solaris when no tape is in the drive (Solaris does not
827 have the detailed errno found on Linux). Added Solaris specific code.
828 Note, this may apply to other OSes as well.
829 - The examples directory has a new bacula_mail_summary.sh file that
830 creates a single email summary of any number of jobs. Submitted by
832 - Add nagios plugin to the examples directory. Submitted by
834 - Modify most restore error messages to be queued so that they
835 appear at the end of the job rather than mixed with the restore
836 listing where they could be "lost".
837 - Apply patch supplied by user (slightly modified) to fix
838 correct detection of holes in block devices and FIFOs.
840 - Added a report.pl program to the examples directory from Jonas Bjorklund.
841 - Add two new queries to query.sql provided by Arno. One
842 list volumes known to the Storage device, and the other
843 lists volumes possibly needing replacement (error, ...).
844 - Implement new code for changing userid and group at startup. This
845 should get Bacula into the correct groups.
846 - Implement support for removable filesystems -- device type directive
847 and mount, unmount directives.
848 - Transfer rates are now presented in a more readable format thanks
849 to a user submission.
850 - SD is now aware of what volumes are mounted. More information is printed
851 in the Status report. You must take much more care now to unmount
852 devices prior to removing tapes that Bacula has open or prior to
853 changing a magazine. Don't forget to do a mount afterwards or the
854 device will be blocked.
855 - The Pool Maximum Volumes directive is now respected in all places.
856 - A Storage device can now be specified in a Pool resource. It will override
857 all other Storage specifications.
858 - Most but not all directives accept true/false in place of yes/no.
859 - A patch from Karl Hakimian that reads JobIds, FileIndexes
860 from a database table for restore.
861 - There are a number of new tables. Some such as the Location table are
862 designed for user use in doing Volume Management software.
863 - Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to
864 accept time qualifiers.
865 - Implement jobuid to replace old usage of job in keywords as
866 suggested by Eric Bollengier.
867 - Implement write variables for Python to set Priority (anytime), and
868 Job Level, only during JobInit event.
869 - Use the keyword ujobid to mean the unique job id; job or jobname
870 to mean the Job name given on the Name directive, and jobid to
871 be the numeric (non-unique) job id.
872 - Allow the SD to use multiple drives during a backup/restore (only
874 - Integrate addition of line count limitation to bsmtp -l from
875 Sebastian Stark <stark at tuebingen.mpg.de>
876 - Split the bacula start/start script into four files:
877 bacula -- starts and stops calling other scripts
878 bacula-ctl-dir -- starts/stops the director
879 bacula-ctl-fd -- starts/stops the File daemon
880 bacula-ctl-sd -- starts/stops the Storage daemon
881 - Remove automatic case folding on Windows FDs. You must
882 explicitly use the 'Ignore Case = yes' option.
883 - Implement wild program in tools directory for testing
884 wild-cards. Almost identical to the regex program.
885 - Use the new bregex.c to implement Regex expressions on Win32.
886 - Apply patch from Christopher Hull
887 - Allow multiple connections to database with different
889 - Invalidate the scheduler when doing a reload. Fixes seg
890 fault, but still 60 second window.
891 - Additional info in Reschedule message.
892 - Use set_jcr_job_status() everywhere to prevent loss of
894 - Display peer IP in FD if error from connecting DIR.
895 - Don't increment file count for DIRBEGIN.
896 - Replace illegal characters in Win32 filename by _.
897 - Add SE_CREATE_PERMANENT_NAME privilege in Win32.
898 - Hash hard link filenames rather than linked list (performance).
899 - Fix for security failure in chdir on Win32.
900 - Add CreateDirectoryA/W win32 API entry points.
901 - programs to duplicate Bacula's base64 algorithm using standard
902 routines. This fixes bugs #296, and 565. Patch submitted by
904 - Fixes to reloading the Dir conf file from Eric Bollengier and Christopher
906 - Modify LICENSE to correct some problems pointed out by Debian.
907 - Apply a patch submitted by cesarb in bug #606 to implement O_NOATIME support.
908 O_NOATIME is a open() flag which makes it possible to read a file without
909 updating the inode atime (and also without the inode ctime update which
910 happens if you try to set the atime back to its previous value). It also
911 prevents a race condition when two programs are reading the same file, but
912 only one does not want to change the atime. It's most useful for backup
913 programs and file integrity checkers (and bacula can fit on both
915 You enable it in the Bacula FileSet Options resource by setting:
917 The effect of this option is similar to the keepatime option except
918 it is more efficient and avoids modifying ctime.
919 - Implement a pile of new man pages contributed by Jose Tallon.
920 - Modify the database format for handling Migration jobs:
921 Add PriorJobId, RealEndTime to Job table
923 Remove Stripe from JobMedia record (not used, wasting space)
924 Add ScratchPoolId, RecyclePoolId, Enabled to Media record
925 Add Cost to Location table.
926 Enabled to Media table and Location table.
927 - Security: harden authentication failure in FD by single threading errors
928 and forcing a 6 second wait.
929 - If using GCC (actually g++) add the following compiler flags
930 -fno-strict-aliasing -fno-exceptions -fno-rtti
931 - Turn on new bsnprintf() code. The reason for this code is to
932 eliminate the security problems associated with using the
933 system libraries print routines.
934 - Implement job report that indicates where Storage and Pool
935 came from -- with overrides and Pool storage and NextPool,
936 it is all very complicated.
937 - Add more detail (Storage, Device) to list of volumes printed
939 - Add new VOLMGMT message class. No messages are yet sent with this
941 - Improved Bacula rescue procedures -- see the Disaster Recovery
942 chapter of the manual
943 - Add spooling/despooling info in status output of SD.
944 - Add Comment field to llist of a volume.
945 - Allow true/false in many but not all yes/no directives.
946 - The Bacula source code is now copyrighted by the Free Software
947 Foundation Europe. The Developer's Guide documents the new procedures,
948 and the LICENSE file has been updated.
949 - Apply Jaime Ventura's patch that implements the Messages resource
950 Mail On Success directive.
951 - The Client returns its Version string, which is printed in the Job
953 - The Client returns whether or not VSS and Encryption are used, which
954 are printed in the Job report.
956 Additional Features Added for Win32:
957 - Added DriveType directive to the Director's Include Option FileSet
958 resource. Allowed values are: fixed, removable, cdrom, and remote. There
959 is only an implementation for Windows because it is the only platform that
960 has the concept of drives.
962 - Adds EnhancedWild directive to the Director's Include Option FileSet
963 resource. Allowed values are: yes and no.
965 When EnhancedWild is enabled then the processing of the
966 Wild, WildDir and WildFile is changed in the following ways.
968 Patterns conform to Posix
969 \ is not a special character in character classification []
970 To match a - it must be the first or last character
971 To match a ] it must be the first character
973 fnmatch option FNM_FILE_NAME is specified * doesn't match a /
974 so it won't match multiple directory levels in a path
976 - Relative WildFile patterns (ones without a leading /) match
977 against the filename portion. This in combination with the
978 FNM_FILE_NAME fnmatch() flag makes directives such as WildFile =
979 abc*.def work as expected.
981 - Adds support for the shell's feature of brace expansion.
983 Here is an example where braces allow 24 lines to be expressed in 5.
985 # Exclude directories full of lots and lots of useless little files
986 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Cookies"
987 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Recent"
988 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/History"
989 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temp"
990 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temporary Internet Files"
