2 Release Notes for Bacula 1.38.1
4 Bacula code: Total files = 420 Total lines = 138,440 (*.h *.c *.in)
5 20,440 additional lines of code since version 1.36.3
8 - Fix several problems with PostgreSQL scripts.
9 - Critical: allow restore of the first file of non-portable Win32 backup.
10 - Important: with muliple concurrent jobs the autochanger could get
11 confused because of a missing mutex.
12 - Fix accessing last slot in label and update slots.
13 - Modify configure.in to add execute option to sqlite3 catalog
15 - Create update_xxx_table_8_to_9 scripts for updatedb
16 - Move the -lcrypt for PostgreSQL after the PostgreSQL libs in
17 autoconf/bacula-macros/db.m4 as suggested by user. Fixes bug #457.
18 - Remove @STATIC_CONS@ from tray-monitor Makefile as suggested
19 by user. Fixes bug #456.
20 - AMD64 users see compiler bug warning below!!!!!!!!!
22 Major Changes in 1.38:
23 - Fixed out of order Volumes in restore.
24 - Improved algorithm for reserving drives in multiple drive
25 autochangers. Autochange users MUST use the new Autochanger
26 resource in the Storage daemon.
27 - There is a new database format that is not compatible
28 with previous databases. You must upgrade if converting
29 from 1.36.x. No changes from version 1.37.30.
30 - The Director, Storage daemon, and File daemons are
31 Deamons are not compatible with prior versions.
32 All FDs must be upgraded at the same time.
33 - Support for ANSI/IBM labels.
34 - Faster database inserts due to combining the MD5/SHA1 into
35 the attributes record, eliminating one INSERT/file backed up.
36 - Python Event support has been added. See below for
37 configuration and details. The implementation is somewhat minimal,
38 so the functionality is not complete. The Python interface
39 has not been extensively tested, so please consider it BETA.
40 - DVD writing support, using parts, and some new directives in
41 the Device resource of the Storage configuration file thanks
42 to Nicolas Boichat. Please note that this code is still
43 BETA and should be carefully tested before using in
45 - Seven new options keywords in a FileSet resource:
46 ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
47 and regexfile thanks to Pruben Guldberg). See below for details.
48 - Restore of all files for a Job or set of jobs even if the file
49 records have been removed from the catalog.
50 - Restore of a directory (non-recursive, i.e. only one level).
51 - Support for TLS (ssl) between all the daemon connections thanks
53 - Any Volume in the Pool named Scratch may be reassigned to any
54 other Pool when a new Volume is needed.
55 - You may clone a Job and thus write (almost) the same data
56 to multiple Volumes simultaneously (see below). Actually,
57 any Job may start any other Job with this mechanism, so it
58 also be used to group jobs.
59 - Unicode filename support for Win32 (thanks to Thorsten Engel)
60 - Volume Shadow Copy support for Win32 thus the capability to
61 backup exclusively opened files (thanks to Thorsten Engel).
62 A VSS enabled Win32 FD is available. You must explicitly
63 turn on VSS with "Enable VSS = yes" in your FileSet resource.
64 - New manual format with an index (thanks to Karl Cunningham).
65 - New Web site format (thanks to Michael Scherer).
67 - Web-bacula, previously a separate project by Juan Luis Frances,
68 is now included in the Bacula GUI release. This is a management
69 level tool for reporting the state of Bacula jobs.
70 - The code is now Internationalized so that it can be localized
71 in native languages. Thanks to Nicolas Boichat.
74 - New Job directive "Prefer Mounted Volumes = yes|no" causes the
75 SD to select either an Autochanger or a drive with a valid
76 Volume already mounted in preference. If none is available,
77 it will select the first available drive.
78 - New Run directive in Job resource of DIR. It permits
79 cloning of jobs. To clone a copy of the current job, use
80 Run = "job-name level=%l since=\"%s\""
81 Note, job-name is normally the same name as the job that
82 is running but there is no restriction on what you put. If you
83 want to start the job by hand and use job overrides such as
84 storage=xxx, realize that the job will be started with the
85 default storage values not the overrides. The level=%l guarantees
86 that the chosen level of the job is the same, and the since=...
87 ensures that the job uses *exactly* the same time/date for incremental
88 and differential jobs. The since=... is ignored when level=Full.
89 A cloned job will not start additional clones, so it is not possible
91 - New Options keywords in a FileSet directive (backported to 1.36.3):
93 Will do a wild card match against directories (files will not
96 Will do a wild card match against files (directories will not
99 Will do a regular expression match against directories (files
100 will not be matched).
102 Will do a regular expression match against files( directories
103 will not be matched).
104 - IgnoreCase = yes | no
105 Will ignore case in wild card and regular expression matches.
106 This is handy for Windows where filename case is not significant.
108 where string is a filesystem type: ext2, jfs, ntfs, proc,
109 reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660. For ext3
110 systems, use ext2. You may have multiple fstype directives
111 and thus permit multiple filesystem types. If the type
112 specified on the fstype directive does not match the
113 filesystem for a particular directive, that directory will
114 not be backed up. This directive can be used to prevent
115 backing up non-local filesystems.
116 - HFS Plus Support = yes | no
117 If set, Mac OS X resource forks will be saved and restored.
118 - Label Type = ANSI | IBM | Bacula
119 Implemented in Director Pool resource and in SD Device resource.
120 If it is specified in the SD Device resource, it will take
121 precedence over the value passed from the Director to the SD.
122 - Check Labels = yes | no
123 Implemented in the SD Device resource. If you intend to read
124 ANSI or IBM labels, this *must* be set. Even if the volume
125 is not ANSI labeled, you can set this to yes, and Bacula will
126 check the label type.
127 - Scripts Directory = <directory> name. Defines the directory from
128 which Bacula scripts will be called for events. In fact, Bacula
129 appends this name to the standard Python list of search directories,
130 so the script could also be in any of the Python system directories.
131 - In FileSet, you can exclude backing up of hardlinks (if you have
132 a lot, it can be very expensive), by using:
134 in the Options section. Patch supplied by David R Bosso. Thanks.
135 - MaximumPartSize = bytes (SD, Device resource)
136 Defines the maximum part size.
137 - Requires Mount = Yes/No (SD, Device resource)
138 Defines if the device require to be mounted to be read, and if it
139 must be written in a special way. If it set, the following directives
140 must be defined in the same Device resource:
141 + Mount Point = directory
142 Directory where the device must be mounted.
143 + Mount Command = name-string
144 Command that must be executed to mount the device. Before the command
145 is executed, %a is replaced with the Archive Device, and %m with the
147 + Unmount Command = name-string
148 Command that must be executed to unmount the device. Before the
149 command is executed, %a is replaced with the Archive Device, and
150 %m with the Mount Point.
151 + Write Part Command = name-string
152 Command that must be executed to write a part to the device. Before
153 the command is executed, %a is replaced with the Archive Device, %m
154 with the Mount Point, %n with the current part number (0-based),
155 and %v with the current part filename.
156 + Free Space Command = name-string
157 Command that must be executed to check how much free space is left
158 on the device. Before the command is executed, %a is replaced with
159 the Archive Device, %m with the Mount Point, %n with the current part
160 number (0-based), and %v with the current part filename.
161 - Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource)
162 If this directive is set to yes (default no), a new part file will be
163 created after the job is finished.
164 - A pile of new Directives to support TLS. Please see the TLS chapter
168 - "python restart" restarts the Python interpreter. Rather brutal, make
169 sure no Python scripts are running. This permits you to change
170 a Python script and get Bacula to use the new script.
172 New configure options:
173 - --with-libintl-prefix for defining alternate locations for
174 the NLS internationalization libraries. Not normally required.
175 - --datadir for defining where the language files will be installed
176 required only if you do not want the default /usr/share.
179 - If you use an Autochanger, you MUST update your SD conf file
180 to use the new Autochanger resource. Otherwise, certain commands
181 such as "update slots" may not work.
182 - You must add --with-python=[DIR] to the configure command line
183 if you want Python support. Python 2.2, 2.3 and 2.4 should be
184 automatically detected if in the standard place.
185 - When linking with --with-python, there are a few warnings that
187 - You must either create a new catalog database or upgrade your
188 old database. After installation, run from your scripts
191 ./upgrade_bacula_tables
193 You can also find this script in the <bacula-source>/src/cats
195 - The Director, Storage daemon, and File daemons are
196 Deamons are not compatible with prior versions.
197 All FDs must be upgraded at the same time.
198 - You must add --with-openssl to the configure command line if
199 you want TLS communications encryption support.
200 - Disk seeking during restores does not yet work correctly in
201 all cases, so it is turned off.
202 - Note, with gcc (GCC) 4.0.1 20050727 (Red Hat 4.0.1-5) on an
203 AMD64 CPU running 64 bit CentOS4, there is a compiler bug that
204 generates bad code that causes Bacula to segment fault.
205 Typically you will see this in the Storage daemon first. The
206 solution is to compile Bacula ensuring that no optimization is
207 turned on (normally it is -O2).
208 This same compiler bug has been reported and confirmed with
209 gcc (GCC) 4.0.2 20050901 (prerelease) (SUSE Linux) running on
210 an AMD64 CPU. This for the moment, I would recommend that all
211 users of GCC 4.0.1 or greater turn off all optimization when
216 - Security fixes for temp files created in mtx-changer, during
217 ./configure, and during making of Rescue disk.
218 - A new script, dvd-handler, in the scripts directory,
219 which is designed to be used as parameters to Write Part Command and
220 Free Space Command. They need the dvd+rw-tools to be installed
221 (http://fy.chalmers.se/~appro/linux/DVD+RW/) AND, the growisofs
222 program must be patched using the
223 <bacula-source>/patches/dvd+rw-tools-5.21.4.10.8.bacula.patch
224 You must have Python installed to run the scripts.
225 - Part files support: File volumes can now be split into multiple
226 files, called "parts".
227 - For the details of the Python scripting support, please see the new
228 Python Scripting chapter in the manual.
