2 Release Notes for Bacula 1.37.12
4 Bacula code: Total files = 419 Total lines = 124,877 (*.h *.c *.in)
6 Note! The DB has been upgraded from version 8 to 9 and requres
10 - This version has a new DIR <--> SD protocol. Both must be
11 upgraded at the same time.
12 - This version has a new database format that is not compatible
13 with previous databases. The upgrade scripts should work, but
14 they are not yet tested.
15 - SQLite3 support, but it seems to run at 1/2 to 1/4 the speed of
17 - First cut at ANSI labels.
18 - New communications protocol between DIR and SD to reserve
19 drives. The DIR and SD are no longer compatible with 1.36 or
21 - Preliminary Python Event support has been added. See below for
22 configuration and details.
23 - DVD writing support, using parts, and a lot of new directives in
24 the Device resource of the Storage configuration file.
25 - Seven new options keywords in a FileSet resource:
26 ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
27 and regexfile. See below for details.
30 - New Run directive in Job resource of DIR. It permits
31 cloning of jobs. To clone a copy of the current job, use
32 Run = "job-name level=%l since=\"%s\""
33 Note, job-name is normally the same name as the job that
34 is running but there is no restriction on what you put. If you
35 want to start the job by hand and use job overrides such as
36 storage=xxx, realize that the job will be started with the
37 default storage values not the overrides. The level=%l guarantees
38 that the chosen level of the job is the same, and the since=...
39 ensures that the job uses *exactly* the same time/date for incremental
40 and differential jobs. The since=... is ignored when level=Full.
41 A cloned job will not start additional clones, so it is not possible
43 - New Options keywords in a FileSet directive:
45 Will do a wild card match against directories (files will not
48 Will do a wild card match against files (directories will not
51 Will do a regular expression match against directories (files
54 Will do a regular expression match against files( directories
56 - IgnoreCase = yes | no
57 Will ignore case in wild card and regular expression matches.
58 This is handy for Windows where filename case is not significant.
60 where string is a filesystem type: ext2, jfs, ntfs, proc,
61 reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660. For ext3
62 systems, use ext2. You may have multiple fstype directives
63 and thus permit multiple filesystem types. If the type
64 specified on the fstype directive does not match the
65 filesystem for a particular directive, that directory will
66 not be backed up. This directive can be used to prevent
67 backing up non-local filesystems.
68 - HFS Plus Support = yes | no
69 If set, Mac OS X resource forks will be saved and restored.
70 - Label Type = ANSI | IBM | Bacula
71 Implemented in Director Pool resource and in SD Device resource.
72 If it is specified in the SD Device resource, it will take
73 precedence over the value passed from the Director to the SD.
74 IBM is not yet implemented.
75 - Check Labels = yes | no
76 Implemented in the SD Device resource. If you intend to read
77 ANSI or IBM labels, this *must* be set. Even if the volume
78 is not ANSI labeled, you can set this to yes, and Bacula will
80 - Scripts Directory = <directory> name. Defines the directory from
81 which Bacula scripts will be called for events. In fact, Bacula
82 appends this name to the standard Python list of search directories,
83 so the script could also be in any of the Python system directories.
84 - In FileSet, you can exclude backing up of hardlinks (if you have
85 a lot, it can be very expensive), by using:
87 in the Options section. Patch supplied by David R Bosso. Thanks.
88 - MaximumPartSize = bytes (SD, Device resource)
89 Defines the maximum part size.
90 - Requires Mount = Yes/No (SD, Device resource)
91 Defines if the device require to be mounted to be read, and if it
92 must be written in a special way. If it set, the following directives
93 must be defined in the same Device resource:
94 + Mount Point = directory
95 Directory where the device must be mounted.
96 + Mount Command = name-string
97 Command that must be executed to mount the device. Before the command
98 is executed, %a is replaced with the Archive Device, and %m with the
100 + Unmount Command = name-string
101 Command that must be executed to unmount the device. Before the
102 command is executed, %a is replaced with the Archive Device, and
103 %m with the Mount Point.
104 + Write Part Command = name-string
105 Command that must be executed to write a part to the device. Before
106 the command is executed, %a is replaced with the Archive Device, %m
107 with the Mount Point, %n with the current part number (0-based),
108 and %v with the current part filename.
109 + Free Space Command = name-string
110 Command that must be executed to check how much free space is left
111 on the device. Before the command is executed, %a is replaced with
112 the Archive Device, %m with the Mount Point, %n with the current part
113 number (0-based), and %v with the current part filename.
114 - Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource)
115 If this directive is set to yes (default no), a new part file will be
116 created after the job is finished.
119 - "python restart" restarts the Python interpreter. Rather brutal, make
120 sure no Python scripts are running. This permits you to change
121 a Python script and get Bacula to use the new script.
124 - You must add --with-python=[DIR] to the configure command line
125 if you want Python support. Python 2.2 and 2.3 should be automatically
126 detected if in the standard place.
127 - With Python 2.2 version, the link of the Director gets a few linker
128 warnings due to the fact that Python pulls in some old non-secure
130 - With Python 2.3, there are a few compiler warnings.
131 - You must either create a new catalog database or upgrade your
132 old database (upgrade scripts not yet tested).
135 - 2 new scripts, dvd-writepart and dvd-freespace, in the scripts directory,
136 which are designed to be used as parameters to Write Part Command and
137 Free Space Command. They need the dvd+rw-tools to be installed
138 (http://fy.chalmers.se/~appro/linux/DVD+RW/).
139 - Part files support: File volumes can now be splitted in multiple
140 files, called "parts".
141 - Python scripting support:
142 A Python script will be called at particular points or conditions
143 in Bacula called Events. The currently defined Events are called:
145 StartJob, EndJob, NewVolume
147 Where StartJob is called before the RunBeforeJob, EndJob is called
148 after RunAfterJob, and NewVolume, is called before all other
149 "methods" of obtaining a new Volume name, when one is needed.
151 The Python script of the same name as the Event name (but with a .py)
152 is called from the Scripts Directory (a directive defined in the
153 Director resource). Note, both the Filename, and the name of
154 the function in the file must correspond to the Event name.
156 Once the Python script gets control, it can have access to Bacula
161 The script is called with one argument, typically called j. This
162 argument *must* be passed unchanged to each bacula function. The
163 format of the call is slightly different for reading Bacula
164 variable and for writing bacula variables. See below.
166 Bacula variables can be read with:
168 bacula.get(j, "Variable-name")
170 where j is the argument passed to the function, and Variable-name
171 is on of the following:
173 JobId, Client, Pool, Storage, Catalog, MediaType, NumVols, DirName,
174 Level, Type, Job, JobName, JobStatus
176 Bacula varibles can be set using Python keyword arguments:
178 bacula.set(jcr=j, VolumeName="xyz")
180 The two currently implemented writable "variables" are:
182 VolumeName and JobReport
184 It is possible to submit a Bacula run command with the following:
186 bacula.run(j, "run kernsave client=Matou storage=File")
188 this function returns the JobId of the job that was started. If
189 there is an error, the return value is zero.
193 == File EndJob.py ===
197 jobid = bacula.get(j, "JobId")
198 client = bacula.get(j, "Client")
199 bacula.set(jcr=j, JobReport="EndJob output: JobId=%d Client=%s.\n" % (jobid, client))
201 startid = bacula.run(j, "run kernsave")
202 print "Python started jobid=", startid
207 == File NewVolume.py ===
211 jobid = bacula.get(j, "JobId")
212 print "JobId=", jobid
213 client = bacula.get(j, "Client")
214 print "Client=" + client
215 numvol = bacula.get(j, "NumVols");
216 print "NumVols=", numvol
217 bacula.set(jcr=j, JobReport="New Volume set for Job.\n")
218 bacula.set(jcr=j, VolumeName="TestA-001")
