2 Release Notes for Bacula 1.37.6
4 Bacula code: Total files = 414 Total lines = 123,723 (*.h *.c *.in)
8 - This version has a new database format that is not compatible
9 with previous databases. The upgrade scripts should work, but
10 they are not yet tested.
11 - SQLite3 support, but it seems to run at 1/2 to 1/4 the speed of
13 - First cut at ANSI labels.
14 - New communications protocol between DIR and SD to reserve
15 drives. The DIR and SD are no longer compatible with 1.36 or
17 - Preliminary Python Event support has been added. See below for
18 configuration and details.
19 - DVD writing support, using parts, and a lot of new directives in
20 the Device resource of the Storage configuration file.
21 - Seven new options keywords in a FileSet resource:
22 ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
23 and regexfile. See below for details.
26 - New Run directive in Job resource of DIR. It permits
27 cloning of jobs. To clone a copy of the current job, use
28 Run = "job-name level=%l since=\"%s\""
29 Note, job-name is normally the same name as the job that
30 is running but there is no restriction on what you put. If you
31 want to start the job by hand and use job overrides such as
32 storage=xxx, realize that the job will be started with the
33 default storage values not the overrides. The level=%l guarantees
34 that the chosen level of the job is the same, and the since=...
35 ensures that the job uses *exactly* the same time/date for incremental
36 and differential jobs. The since=... is ignored when level=Full.
37 A cloned job will not start additional clones, so it is not possible
39 - New Options keywords in a FileSet directive:
41 Will do a wild card match against directories (files will not
44 Will do a wild card match against files (directories will not
47 Will do a regular expression match against directories (files
50 Will do a regular expression match against files( directories
52 - IgnoreCase = yes | no
53 Will ignore case in wild card and regular expression matches.
54 This is handy for Windows where filename case is not significant.
56 where string is a filesystem type: ext2, jfs, ntfs, proc,
57 reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660. For ext3
58 systems, use ext2. You may have multiple fstype directives
59 and thus permit multiple filesystem types. If the type
60 specified on the fstype directive does not match the
61 filesystem for a particular directive, that directory will
62 not be backed up. This directive can be used to prevent
63 backing up non-local filesystems.
64 - HFS Plus Support = yes | no
65 If set, Mac OS X resource forks will be saved and restored.
66 - Label Type = ANSI | IBM | Bacula
67 Implemented in Director Pool resource and in SD Device resource.
68 If it is specified in the SD Device resource, it will take
69 precedence over the value passed from the Director to the SD.
70 IBM is not yet implemented.
71 - Check Labels = yes | no
72 Implemented in the SD Device resource. If you intend to read
73 ANSI or IBM labels, this *must* be set. Even if the volume
74 is not ANSI labeled, you can set this to yes, and Bacula will
76 - Scripts Directory = <directory> name. Defines the directory from
77 which Bacula scripts will be called for events. In fact, Bacula
78 appends this name to the standard Python list of search directories,
79 so the script could also be in any of the Python system directories.
80 - In FileSet, you can exclude backing up of hardlinks (if you have
81 a lot, it can be very expensive), by using:
83 in the Options section. Patch supplied by David R Bosso. Thanks.
84 - MaximumPartSize = bytes (SD, Device resource)
85 Defines the maximum part size.
86 - Requires Mount = Yes/No (SD, Device resource)
87 Defines if the device require to be mounted to be read, and if it
88 must be written in a special way. If it set, the following directives
89 must be defined in the same Device resource:
90 + Mount Point = directory
91 Directory where the device must be mounted.
92 + Mount Command = name-string
93 Command that must be executed to mount the device. Before the command
94 is executed, %a is replaced with the Archive Device, and %m with the
96 + Unmount Command = name-string
97 Command that must be executed to unmount the device. Before the
98 command is executed, %a is replaced with the Archive Device, and
99 %m with the Mount Point.
100 + Write Part Command = name-string
101 Command that must be executed to write a part to the device. Before
102 the command is executed, %a is replaced with the Archive Device, %m
103 with the Mount Point, %n with the current part number (0-based),
104 and %v with the current part filename.
105 + Free Space Command = name-string
106 Command that must be executed to check how much free space is left
107 on the device. Before the command is executed, %a is replaced with
108 the Archive Device, %m with the Mount Point, %n with the current part
109 number (0-based), and %v with the current part filename.
110 - Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource)
111 If this directive is set to yes (default no), a new part file will be
112 created after the job is finished.
115 - "python restart" restarts the Python interpreter. Rather brutal, make
116 sure no Python scripts are running. This permits you to change
117 a Python script and get Bacula to use the new script.
120 - You must add --with-python=[DIR] to the configure command line
121 if you want Python support. Python 2.2 and 2.3 should be automatically
122 detected if in the standard place.
123 - With Python 2.2 version, the link of the Director gets a few linker
124 warnings due to the fact that Python pulls in some old non-secure
126 - With Python 2.3, there are a few compiler warnings.
127 - You must either create a new catalog database or upgrade your
128 old database (upgrade scripts not yet tested).
131 - 2 new scripts, dvd-writepart and dvd-freespace, in the scripts directory,
132 which are designed to be used as parameters to Write Part Command and
133 Free Space Command. They need the dvd+rw-tools to be installed
134 (http://fy.chalmers.se/~appro/linux/DVD+RW/).
135 - Part files support: File volumes can now be splitted in multiple
136 files, called "parts".
137 - Python scripting support:
138 A Python script will be called at particular points or conditions
139 in Bacula called Events. The currently defined Events are called:
141 StartJob, EndJob, NewVolume
143 Where StartJob is called before the RunBeforeJob, EndJob is called
144 after RunAfterJob, and NewVolume, is called before all other
145 "methods" of obtaining a new Volume name, when one is needed.
147 The Python script of the same name as the Event name (but with a .py)
148 is called from the Scripts Directory (a directive defined in the
149 Director resource). Note, both the Filename, and the name of
150 the function in the file must correspond to the Event name.
152 Once the Python script gets control, it can have access to Bacula
157 The script is called with one argument, typically called j. This
158 argument *must* be passed unchanged to each bacula function. The
159 format of the call is slightly different for reading Bacula
160 variable and for writing bacula variables. See below.
162 Bacula variables can be read with:
164 bacula.get(j, "Variable-name")
166 where j is the argument passed to the function, and Variable-name
167 is on of the following:
169 JobId, Client, Pool, Storage, Catalog, MediaType, NumVols, DirName,
170 Level, Type, Job, JobName, JobStatus
172 Bacula varibles can be set using Python keyword arguments:
174 bacula.set(jcr=j, VolumeName="xyz")
176 The two currently implemented writable "variables" are:
178 VolumeName and JobReport
180 It is possible to submit a Bacula run command with the following:
182 bacula.run(j, "run kernsave client=Matou storage=File")
184 this function returns the JobId of the job that was started. If
185 there is an error, the return value is zero.
189 == File EndJob.py ===
193 jobid = bacula.get(j, "JobId")
194 client = bacula.get(j, "Client")
195 bacula.set(jcr=j, JobReport="EndJob output: JobId=%d Client=%s.\n" % (jobid, client))
197 startid = bacula.run(j, "run kernsave")
198 print "Python started jobid=", startid
203 == File NewVolume.py ===
207 jobid = bacula.get(j, "JobId")
208 print "JobId=", jobid
209 client = bacula.get(j, "Client")
210 print "Client=" + client
211 numvol = bacula.get(j, "NumVols");
212 print "NumVols=", numvol
213 bacula.set(jcr=j, JobReport="New Volume set for Job.\n")
214 bacula.set(jcr=j, VolumeName="TestA-001")
