2 Release Notes for Bacula 1.37.24
4 Bacula code: Total files = 433 Total lines = 140,329 (*.h *.c *.in)
7 - There is a new database format that is not compatible
8 with previous databases. You must upgrade if converting
10 - The Director, Storage daemon, and File daemons are
11 Deamons are not compatible with prior versions.
12 All FDs must be upgraded at the same time.
13 - Multiple drive autochanger support.
14 - Support for ANSI/IBM labels.
15 - New communications protocol between DIR and SD to reserve
17 - Faster database inserts due to combining the MD5/SHA1 into
18 the attributes record, eliminating one INSERT/file backed up.
19 - Python Event support has been added. See below for
20 configuration and details. Unfortunately, it is not yet complete
21 and the only really useful function is defining a new
23 - DVD writing support, using parts, and a lot of new directives in
24 the Device resource of the Storage configuration file thanks
26 - Seven new options keywords in a FileSet resource:
27 ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
28 and regexfile thanks to Pruben Guldberg). See below for details.
29 - Restore of all files for a Job or set of jobs even if the file
30 records have been removed from the catalog.
31 - Restore of a directory (non-recursive, i.e. only one level).
32 - Support for TLS (ssl) between all the daemon connections thanks
33 to Landon Fuller. wx-console and gnome-console are not yet
35 - Any Volume in the Pool named Scratch may be reassigned to any
36 other Pool when a new Volume is needed.
37 - Seeking on disk Volumes during restore.
38 - You may clone a Job and thus write (almost) the same data
39 to multiple Volumes simultaneously (see below). Actually,
40 any Job may start any other Job with this mechanism, so it
41 also be used to group jobs.
42 - Unicode filename support for Win32 (thanks to Thorsten Engel)
43 - Volume Shadow Copy support for Win32 thus the capability to
44 backup exclusively opened files (thanks to Thorsten Engel).
45 - New manual format with an index (thanks to Karl Cunningham).
46 - New Web site format (thanks to Michael Scherer).
47 - SQLite3 support, but it seems to run at 1/2 to 1/4 the speed of
49 - Web-bacula, previously a separate project by Juan Luis Frances,
50 is now included in the Bacula GUI release (yet to be fully
54 - New Job directive "Prefer Mounted Volumes = yes|no" causes the
55 SD to select either an Autochanger or a drive with a valid
56 Volume already mounted in preference. If none is available,
57 it will select the first available drive.
58 - New Run directive in Job resource of DIR. It permits
59 cloning of jobs. To clone a copy of the current job, use
60 Run = "job-name level=%l since=\"%s\""
61 Note, job-name is normally the same name as the job that
62 is running but there is no restriction on what you put. If you
63 want to start the job by hand and use job overrides such as
64 storage=xxx, realize that the job will be started with the
65 default storage values not the overrides. The level=%l guarantees
66 that the chosen level of the job is the same, and the since=...
67 ensures that the job uses *exactly* the same time/date for incremental
68 and differential jobs. The since=... is ignored when level=Full.
69 A cloned job will not start additional clones, so it is not possible
71 - New Options keywords in a FileSet directive:
73 Will do a wild card match against directories (files will not
76 Will do a wild card match against files (directories will not
79 Will do a regular expression match against directories (files
82 Will do a regular expression match against files( directories
84 - IgnoreCase = yes | no
85 Will ignore case in wild card and regular expression matches.
86 This is handy for Windows where filename case is not significant.
88 where string is a filesystem type: ext2, jfs, ntfs, proc,
89 reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660. For ext3
90 systems, use ext2. You may have multiple fstype directives
91 and thus permit multiple filesystem types. If the type
92 specified on the fstype directive does not match the
93 filesystem for a particular directive, that directory will
94 not be backed up. This directive can be used to prevent
95 backing up non-local filesystems.
96 - HFS Plus Support = yes | no
97 If set, Mac OS X resource forks will be saved and restored.
98 - Label Type = ANSI | IBM | Bacula
99 Implemented in Director Pool resource and in SD Device resource.
100 If it is specified in the SD Device resource, it will take
101 precedence over the value passed from the Director to the SD.
102 - Check Labels = yes | no
103 Implemented in the SD Device resource. If you intend to read
104 ANSI or IBM labels, this *must* be set. Even if the volume
105 is not ANSI labeled, you can set this to yes, and Bacula will
106 check the label type.
107 - Scripts Directory = <directory> name. Defines the directory from
108 which Bacula scripts will be called for events. In fact, Bacula
109 appends this name to the standard Python list of search directories,
110 so the script could also be in any of the Python system directories.
111 - In FileSet, you can exclude backing up of hardlinks (if you have
112 a lot, it can be very expensive), by using:
114 in the Options section. Patch supplied by David R Bosso. Thanks.
115 - MaximumPartSize = bytes (SD, Device resource)
116 Defines the maximum part size.
117 - Requires Mount = Yes/No (SD, Device resource)
118 Defines if the device require to be mounted to be read, and if it
119 must be written in a special way. If it set, the following directives
120 must be defined in the same Device resource:
121 + Mount Point = directory
122 Directory where the device must be mounted.
123 + Mount Command = name-string
124 Command that must be executed to mount the device. Before the command
125 is executed, %a is replaced with the Archive Device, and %m with the
127 + Unmount Command = name-string
128 Command that must be executed to unmount the device. Before the
129 command is executed, %a is replaced with the Archive Device, and
130 %m with the Mount Point.
131 + Write Part Command = name-string
132 Command that must be executed to write a part to the device. Before
133 the command is executed, %a is replaced with the Archive Device, %m
134 with the Mount Point, %n with the current part number (0-based),
135 and %v with the current part filename.
136 + Free Space Command = name-string
137 Command that must be executed to check how much free space is left
138 on the device. Before the command is executed, %a is replaced with
139 the Archive Device, %m with the Mount Point, %n with the current part
140 number (0-based), and %v with the current part filename.
141 - Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource)
142 If this directive is set to yes (default no), a new part file will be
143 created after the job is finished.
144 - A pile of new Directives to support TLS. Please see the TLS chapter
148 - "python restart" restarts the Python interpreter. Rather brutal, make
149 sure no Python scripts are running. This permits you to change
150 a Python script and get Bacula to use the new script.
153 - TLS for wx-console is only partially implemented. TLS for
154 the Gnome console is not yet implemented.
155 - You must add --with-python=[DIR] to the configure command line
156 if you want Python support. Python 2.2 and 2.3 should be automatically
157 detected if in the standard place.
158 - With Python 2.2 version, the link of the Director gets a few linker
159 warnings due to the fact that Python pulls in some old non-secure
161 - With Python 2.3, there are a few compiler warnings.
162 - The Python implementation has a few memory leaks not yet cleaned
163 up. As long as you restart Bacula once a month, this shouldn't
165 - You must either create a new catalog database or upgrade your
166 old database (the PostgreSQL upgrade scripts not yet tested).
167 - You must add --with-openssl to the configure command line if
168 you want TLS communications encryption support.
171 - 2 new scripts, dvd-writepart and dvd-freespace, in the scripts directory,
172 which are designed to be used as parameters to Write Part Command and
173 Free Space Command. They need the dvd+rw-tools to be installed
174 (http://fy.chalmers.se/~appro/linux/DVD+RW/).
175 You must have Python installed to run the dvd-freespace script.
176 - Part files support: File volumes can now be splitted in multiple
177 files, called "parts".
179 - For the details of the Python scripting support, please see the new
180 Python Scripting chapter in the manual.
