2 Release Notes for Bacula 5.2.0
4 Bacula code: Total files = 1,110 Total lines = 231,439 (Using SLOCCount)
9 This 5.2.0 version is a major release since the last version 5.0.3.
10 It includes well over 371,803 lines of changes made by 21 contributors
11 and a number of important new features:
15 As always, both the Director and Storage daemon must be upgraded at
18 Older 5.0.x and 3.0.x File Daemons are compatible with the 5.2.0
19 Director and Storage daemons. There should be no need to upgrade older File
27 - Changes in Bvfs (Bacula Virtual FileSystem)
28 - Changes in the Pruning Algorithm
29 - Ability to Verify any specified Job
30 - Additions to RunScript variables
31 - Additions to the Plugin API
34 - Class Based Database Backend Drivers
35 - Hash List Enhancements
37 Some of the above are described below; all the above are
38 described in more detail in the New Features chapter of the
42 ================== Warning !!!!!! ==========================
44 The new pruning algorithm will not allow pruning of jobs that are essential to
45 restore since the last Full backup. This is, of course, correct and desirable,
46 but it is different from older Bacula versions that could inappropriately
47 prune jobs. Pruning of volumes is not affected.
51 To build Bat, you need Qt4 version 4.6.2. If you build with any other
52 version it is likely not to work. If you do not have version 4.6.2, on
53 your system, you can download the Bacula depkgs_qt version 16Dec10.
55 New Catalog format in version 5.2.0
56 -----------------------------------
57 This release of Bacula uses a new catalog format. We provide a set of
58 scripts that permit to convert a 5.0.x (version 12) catalog to 5.2.0 (version
59 14). The Bacula project rpm spec files have been modified to
60 detect the database change and do the upgrade for you. We strongly
61 recommend that you save a copy of your existing database before upgrading
64 The simplest way to upgrade the database assuming you are building from
65 source (i.e. manually):
66 1. Stop any current version of Bacula from running.
67 2. Save a copy of your existing database.
68 3. Configure, build, and install the 5.2.0 version of Bacula
69 Note the new ./configure options in the manuals see the link
70 at the bottom of this file.
71 4. cd <your-scripts-installation-directory>
72 5. ./update_bacula_tables
73 6. If you have multiple catalogs, edit the update_bacula_tables
74 script and put the name of another database, and then
75 execute the script again. Repeat this until all Bacula
76 catalogs have been updated.
77 7. Start the new Bacula. If everything worked, it should
78 not print any error messages.
80 If you start from scratch, you don't need to run the update_bacula_tables
81 script because the create_bacula_tables script automatically creates the new
82 table format. However, if you are using a version of Bacula older than 5.0.0
83 (e.g. 3.0.3) then you need to run the update_bacula_tables script that will
84 be found in the <bacula>/src/cats directory after you run the ./configure
85 command. As mentioned above, before running this script, please backup your
86 catalog database, and when you do running it, be sure shutdown Bacula and be
87 aware that running the script can take some time depending on your database
90 ================================================================
94 Speed and Memory Usage Enhancements:
95 - Implement LZO compression algorithm (need lzo2 headers to activate this option)
96 - New Pruning algoritm -- safer and faster
97 - Use of PostgreSQL cursor when doing large queries, should reduce the
98 memory usage during restore and accurate backups.
99 - limit command in some list commands
100 - Bacula Virtual File System for fast catalog access
101 - Faster crc32 algorithm
103 Security Enhancements:
104 - Additional security against injection of illegal characters
105 - Fix possible fnmatch problem
107 Features Enhancements:
108 - Improvements in ACL and xattr handling on additional platforms:
109 AIX, Darwind, FreeBSD, HPUX, IRIX, Solaris, Tru64
110 - Tray monitor for Windows
111 - New SQL backend and ./configure that permits building multiple catalog
112 backends in one build, and has the main Bacula core code totally independent
113 of the SQL backend, which should simplify packaging (only the
114 libbacsql.so/dll needs to be changed to switch from one database backend
115 to another (e.g. MySQL to PostgreSQL).
116 - Indent lsmark during restore
117 - Disable batch insert config item
118 - Director selection option in bconsole
119 - restorejob command in bconsole
120 - Many additional features for bat such as "brestore" panel
121 - The old bat version browser has been turned off since it does not
122 work correctly and the brestore panel provides the same functionality
123 - Improved hash table for hard links
124 - Additional script variable editing such as %b (JobBytes), %F (JobFiles)
125 and %h (Client Address)
128 - Includes better handling for Windows repares points, mount points, and
130 - New database format
131 - Many new plugin API features
132 - Improved memory handling for restores
133 - Significant stability enhancements to bat
134 - xattr/ACL restore failure are now printed as Warning
135 - A few path name length limits in Windows have been removed.

145 ===========================================================================
147 The 5.0.3 version is significant bug fix update to version 5.0.2.
148 It includes new code and some new features.
149 There is no database change since prior versions of 5.0.
151 Note, if you are running 5.0.0, read the 5.0.1 and 5.0.2 release notes below in
152 the 5.0.1 release section.
157 As always, both the Director and Storage daemon must be upgraded at
160 Older 5.0.x and 3.0.x File Daemons are compatible with the 5.0.3
161 Director and Storage daemons. There should be no need to upgrade older File
164 Changes and New Features:
165 - If a VSS (Windows) snapshot fails, the whole Job is failed, previously
166 it printed a warning message and continued.
167 - New editing codes %b = Job Bytes and %f = Job Files for runscripts
168 - Any non-Bacula project plugins (i.e. third party plugins)
169 must be upgraded to specify AGPLv3 in place of the GPLv2 used previously
170 for the PLUGIN_LICENSE.
171 - The bat Media page text columns can be sorted by clicking on the column.
172 - If possible, the SD will automatically update the catalog Volume size if
173 it does not match the Volume size. The mismatch between the Volume sizes
174 typically occurs when the FD has a comm line drop or the FD crashes.

271 =============================================================================
274 ============= Release 5.0.1 ========================
276 !!!!!!!!!!!!!!! NOTE FOR 5.0.0 USERS !!!!!!!!!!!!!!!!!!!!
277 The Allow Duplicate Jobs directive has been significantly
278 reworked, and the default value has changed. See below.
280 Truncate On Purge has been totally rewritten. See the new
281 features section of the manual.
283 When Volume Poll Interval is set in the SD DEVICE configuration,
284 (default 5 mins), after a certain number of polling tries (approx
285 10) polling will stop and the operator will be asked to
286 resolve the problem. Previously there was no limit, and an
287 error message could be produced at each poll attempt.
288 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
292 - We believe that we have resolved most of the problems
293 concerning canceled or failed jobs being "stuck" in the
294 Director. There is one outstanding problem in the SD when
295 canceling jobs that we will fix in the next major release.
296 If you see jobs that seem to be stuck, in general issuing
297 a cancel command in bconsole should now make them go away.
300 - The default for "Allow Duplicate Jobs" has been changed from
301 no to yes. If you use this directive, please check your
302 conf file, and note the next two items !!!!!!!!!!!!!!!!!!!
303 - AllowHigherDuplicates disabled. It did not work as documented
305 - New directive "CancelLowerLevelDuplicates" See New Features
306 section in the manual.
307 - Truncate on Purge rewritten. See New Features section in the manual.

345 - Fix #1466 about Bogus pruning message
348 1. The default query.sql file is now, except for some comments, empty.
349 The old file, which we no longer support (it is impossible or difficult to
350 make it work on every backend, and the queries are mostly contributed) can
351 be found in <bacula-source>/examples/sample-query.sql. The sample file is
352 not installed by the Makefiles
354 2. When you install the mtx-changer script, you must also install
355 mtx-changer.conf if it does not exist. This new file (mtx-changer.conf) is
356 required for mtx-changer to work, but it is a user configurable file, so on
357 any update, any existing file should not be overwritten.
359 3. Bat should be built on every platform that is capabable of running Qt.
360 However, the Qt code is changing rather quickly and is not always
361 compatible from version to version. We have built and verified bat on Qt
362 4.3.4. We strongly recommend that you do not build and distribute bat with
363 any other version of Qt unless you personally test it. To build against Qt
364 4.3.4, download the depkgs-qt package from the Bacula Source Forge download
365 location, read the README file and follow the instructions.
367 If you are building for Bacula version 5.0.0, please ensure that you do not
368 have qmake-qt4 loaded on your system. If you do, either remove it or
369 rename it before trying to build bat. If you do not, bat will probably be
370 built using the shared objects on your system. For Bacula 5.0.1 and later,
371 this problem (bug) does not exist.
373 depkgs-qt does not install Qt on your system, nor does it interfere with
374 you having any other version of Qt installed on your system. Once you
375 build bat with depkgs-qt, it should *not* use the Qt shared objects, but
376 rather they will be linked into the program. After fully installing bat
377 (make install), you can run "ldd bat" to see what shared objects it will
378 use. If any Qt shared objects are referenced, something has gone wrong.
380 4. Unless absolutely necessary, we recommend that you do not define any
381 special library environment variables that apply to the ./configure -- for
382 example: LIBDIR=/... ./configure <your-options> is strongly discouraged.
383 Doing so, could potentially cause Bacula to be linked against the wrong
386 5. The Bacula project strongly recommends that you install Bacula into a
387 single directory, with a few minor exceptions such as the MySQL or
388 PostgreSQL databases. Preferrably this should be /opt/bacula. The full
392 # Recommended configure script for Bacula
395 CFLAGS="-g -O2 -Wall" \
397 --sbindir=${prefix}/bin \
398 --sysconfdir=${prefix}/etc \
399 --docdir=${prefix}/html \
400 --htmldir=${prefix}/html \
401 --with-working-dir=${prefix}/working \
402 --with-pid-dir=${prefix}/working \
403 --with-subsys-dir=${prefix}/working \

408 --enable-tray-monitor \
411 --with-dump-email=${email} \
412 --with-job-email=${email} \
413 --with-smtp-host=localhost \
416 Obviously, the email, and some of the minor options (mysql, postgresql,
417 ...) can be changed to suit your distribution, but the directory names
418 defined above are strongly recommended, and over time the default values in
419 the bacula-dir.conf and bacula-sd.conf will reflect these choices.
421 If you have any questions about this or would like a detailed document
422 describing our recommendations including packaging requirements, please
423 send an email to the bacula-devel list.
425 6. Starting with Bacula version 3.0.0 up to Bacula 5.0.0, the shared
426 libraries that Bacula uses by default are named xxx-1.0.0. Starting with
427 Bacula 5.0.1, we are going to name the libraries using the Bacula version.
428 So in Bacula 5.0.1, the libraries will be named xxx-5.0.1. With future
429 versions, the last digit may or may not change when we distribute patch
430 updates (i.e. the last digit of the version changes). This will depend on
431 whether or not we have changed something in the library. Hopefully this
432 new procedure will resolve some of the incompatibility problems between
433 different versions of the shared objects.
435 7. The default build option for bconsole is conio (my own little console
436 routines). I did this because some years ago, readline was very difficult
437 to maintain -- it and where it was found seemed to change on every release.
438 This generated at the time a number of support problems. It seems to me
439 that since then there have been very few problems with readline. As a
440 consequence, I have no problem if you want to make bconsole with readline
441 enabled. It will actually give some very nice new bconsole command
442 completion functionality that Eric has written. Bottom line: feel free to
443 use readline or not as you please.
445 ==========================================================
449 Release Notes for Bacula 5.0.0
452 -----------------------------------------------------------
453 You might be wondering why this release jumps from 3.0.x to
454 5.0.0 thus skipping version 4.0.0. We have done this for
455 several reasons: first, we wanted a way of distinguishing
456 the numbering system for the Bacula System Enterprise version
457 and the Bacula Project version. So, to do so, we have decided
458 that the first number of the Bacula Project version will always
459 be odd, and the first number of the Enterprise version will always
460 be even. Thus the Bacula Project now moves from 3.0.x to 5.0.x.
461 In addition, we want to keep the Bacula Project version larger
462 than the Enterprise version to indicate that the Bacula Project
463 version is more advanced or has more features than the
464 Enterprise version. For memory, the current Enterprise version
465 is 2.6.1, and the next release (in a few months -- before June 2010)
466 will be version 4.0.0.

519 As always, both the Director and Storage daemon must be upgraded at
520 the same time, and on any given machine, you must run only one version
521 of Bacula. This means that on the Director and Storage daemon machines,
522 you *must* upgrade your File daemon as well.
524 Older 3.0.x and possibly 2.4.x File Daemons are compatible with the 5.0.0
525 Director and Storage daemons. There should be no need to upgrade older File
526 Daemons immediately. However, we recommend that you do so as soon
527 as is reasonable for your situation.
529 ================== Warning !!!!!! ==========================
531 New Catalog format in version 5.0.0 (3.1.9 or later)
532 -----------------------------------------------------
534 This release of Bacula uses a new catalog format. We provide a set of
535 scripts that permit to convert a 3.0.x (version 11) catalog to 5.0.0 (version
536 12). The Bacula project rpms distributed on Source Forge will automatically
537 detect the database change and do the upgrade for you. We strongly
538 recommend that you save a copy of your existing database before upgrading
541 The simplest way to upgrade the database assuming you are building from
543 1. Stop any current version of Bacula from running.
544 2. Save a copy of your existing database.
545 3. Configure, build, and install the 5.0.0 version of Bacula
546 Note the new ./configure options in the manuals see the link
547 at the bottom of this file.
548 4. cd <your-scripts-installation-directory>
549 5. ./update_bacula_tables
550 6. If you have multiple catalogs, edit the update_bacula_tables
551 script and put the name of another database, and then
552 execute the script again. Repeat this until all Bacula
553 catalogs have been updated.
554 7. Start the new Bacula. If everything worked, it should
555 not print any error messages.
557 If you start from scratch, you don't need to run the update_bacula_tables
558 script because the create_bacula_tables script automatically creates the new
559 table format. However, if you are using a version of Bacula older than 3.1.9
560 (e.g. 3.0.3) then you need to run the update_bacula_tables script that will
561 be found in the <bacula>/src/cats directory after you run the ./configure
562 command. As mentioned above, before running this script, please backup your
563 catalog database, and when you do running it, be sure shutdown Bacula and be
564 aware that running the script can take some time depending on your database

569 ================== Warning !!!!!! ==========================
570 If you upgrade a previous Win32 client installation, you must
571 first stop the File daemon, then uninstall it before attempting
572 the upgrade. If you do not do so, the upgrade will probably
573 fail and you will need to manually find and run the
574 Uninstall.exe file, before you can upgrade to the new version.
575 This is because the file locations are different. If you want
576 to save your previous bacula-fd.conf file, please do so before
578 ================================================================
580 ================== Warning !!!!!! ==========================
581 Due to permissions problems on Windows Vista and later systems,
582 we no longer require SYSTEM or Administrator permissions to
583 access the binaries and configuation files. If you wish
584 to restrict access to these files, please see the New Features
585 section of the manual for how to set access control lists.
586 ================================================================
588 Note, the Win32 Installer no longer installs the Bacula Servers
589 (Director and Storage daemon). See the New Features section of
590 the manual for more details.
592 ============ Documentation improvements needed ==================
594 Note!!!!! The 5.0.0+ documentation has a number of known problems:
596 1. We have reduced the number of manuals, which has fixed many
597 of the broken links found in the old 3.0.x version, but there
598 are still some that need fixing.
600 2. Integration of the 3.0.x features into the main manuals has
603 The documentation will not be completed in the near future due to lack
604 manpower. If you are unhappy with this situation as we are, we suggest
605 you help by submitting patches to the documentation. Thanks.
609 This release includes large number of new features and changes.
610 It should be more or less compatible with previous xx.conf files
611 and File daemons providing that you are not using any of the new
614 Please see the New Features chapter of the new manual, which documents
615 some but not all the new features (we are still working on it):
