2 Release Notes for Bacula 1.37.10
4 Bacula code: Total files = 414 Total lines = 123,723 (*.h *.c *.in)
8 - This version has a new DIR <--> SD protocol. Both must be
9 upgraded at the same time.
10 - This version has a new database format that is not compatible
11 with previous databases. The upgrade scripts should work, but
12 they are not yet tested.
13 - SQLite3 support, but it seems to run at 1/2 to 1/4 the speed of
15 - First cut at ANSI labels.
16 - New communications protocol between DIR and SD to reserve
17 drives. The DIR and SD are no longer compatible with 1.36 or
19 - Preliminary Python Event support has been added. See below for
20 configuration and details.
21 - DVD writing support, using parts, and a lot of new directives in
22 the Device resource of the Storage configuration file.
23 - Seven new options keywords in a FileSet resource:
24 ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
25 and regexfile. See below for details.
28 - New Run directive in Job resource of DIR. It permits
29 cloning of jobs. To clone a copy of the current job, use
30 Run = "job-name level=%l since=\"%s\""
31 Note, job-name is normally the same name as the job that
32 is running but there is no restriction on what you put. If you
33 want to start the job by hand and use job overrides such as
34 storage=xxx, realize that the job will be started with the
35 default storage values not the overrides. The level=%l guarantees
36 that the chosen level of the job is the same, and the since=...
37 ensures that the job uses *exactly* the same time/date for incremental
38 and differential jobs. The since=... is ignored when level=Full.
39 A cloned job will not start additional clones, so it is not possible
41 - New Options keywords in a FileSet directive:
43 Will do a wild card match against directories (files will not
46 Will do a wild card match against files (directories will not
49 Will do a regular expression match against directories (files
52 Will do a regular expression match against files( directories
54 - IgnoreCase = yes | no
55 Will ignore case in wild card and regular expression matches.
56 This is handy for Windows where filename case is not significant.
58 where string is a filesystem type: ext2, jfs, ntfs, proc,
59 reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660. For ext3
60 systems, use ext2. You may have multiple fstype directives
61 and thus permit multiple filesystem types. If the type
62 specified on the fstype directive does not match the
63 filesystem for a particular directive, that directory will
64 not be backed up. This directive can be used to prevent
65 backing up non-local filesystems.
66 - HFS Plus Support = yes | no
67 If set, Mac OS X resource forks will be saved and restored.
68 - Label Type = ANSI | IBM | Bacula
69 Implemented in Director Pool resource and in SD Device resource.
70 If it is specified in the SD Device resource, it will take
71 precedence over the value passed from the Director to the SD.
72 IBM is not yet implemented.
73 - Check Labels = yes | no
74 Implemented in the SD Device resource. If you intend to read
75 ANSI or IBM labels, this *must* be set. Even if the volume
76 is not ANSI labeled, you can set this to yes, and Bacula will
78 - Scripts Directory = <directory> name. Defines the directory from
79 which Bacula scripts will be called for events. In fact, Bacula
80 appends this name to the standard Python list of search directories,
81 so the script could also be in any of the Python system directories.
82 - In FileSet, you can exclude backing up of hardlinks (if you have
83 a lot, it can be very expensive), by using:
85 in the Options section. Patch supplied by David R Bosso. Thanks.
86 - MaximumPartSize = bytes (SD, Device resource)
87 Defines the maximum part size.
88 - Requires Mount = Yes/No (SD, Device resource)
89 Defines if the device require to be mounted to be read, and if it
90 must be written in a special way. If it set, the following directives
91 must be defined in the same Device resource:
92 + Mount Point = directory
93 Directory where the device must be mounted.
94 + Mount Command = name-string
95 Command that must be executed to mount the device. Before the command
96 is executed, %a is replaced with the Archive Device, and %m with the
98 + Unmount Command = name-string
99 Command that must be executed to unmount the device. Before the
100 command is executed, %a is replaced with the Archive Device, and
101 %m with the Mount Point.
102 + Write Part Command = name-string
103 Command that must be executed to write a part to the device. Before
104 the command is executed, %a is replaced with the Archive Device, %m
105 with the Mount Point, %n with the current part number (0-based),
106 and %v with the current part filename.
107 + Free Space Command = name-string
108 Command that must be executed to check how much free space is left
109 on the device. Before the command is executed, %a is replaced with
110 the Archive Device, %m with the Mount Point, %n with the current part
111 number (0-based), and %v with the current part filename.
112 - Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource)
113 If this directive is set to yes (default no), a new part file will be
114 created after the job is finished.
117 - "python restart" restarts the Python interpreter. Rather brutal, make
118 sure no Python scripts are running. This permits you to change
119 a Python script and get Bacula to use the new script.
122 - You must add --with-python=[DIR] to the configure command line
123 if you want Python support. Python 2.2 and 2.3 should be automatically
124 detected if in the standard place.
125 - With Python 2.2 version, the link of the Director gets a few linker
126 warnings due to the fact that Python pulls in some old non-secure
128 - With Python 2.3, there are a few compiler warnings.
129 - You must either create a new catalog database or upgrade your
130 old database (upgrade scripts not yet tested).
133 - 2 new scripts, dvd-writepart and dvd-freespace, in the scripts directory,
134 which are designed to be used as parameters to Write Part Command and
135 Free Space Command. They need the dvd+rw-tools to be installed
136 (http://fy.chalmers.se/~appro/linux/DVD+RW/).
137 - Part files support: File volumes can now be splitted in multiple
138 files, called "parts".
139 - Python scripting support:
140 A Python script will be called at particular points or conditions
141 in Bacula called Events. The currently defined Events are called:
143 StartJob, EndJob, NewVolume
145 Where StartJob is called before the RunBeforeJob, EndJob is called
146 after RunAfterJob, and NewVolume, is called before all other
147 "methods" of obtaining a new Volume name, when one is needed.
149 The Python script of the same name as the Event name (but with a .py)
150 is called from the Scripts Directory (a directive defined in the
151 Director resource). Note, both the Filename, and the name of
152 the function in the file must correspond to the Event name.
154 Once the Python script gets control, it can have access to Bacula
159 The script is called with one argument, typically called j. This
160 argument *must* be passed unchanged to each bacula function. The
161 format of the call is slightly different for reading Bacula
162 variable and for writing bacula variables. See below.
164 Bacula variables can be read with:
166 bacula.get(j, "Variable-name")
168 where j is the argument passed to the function, and Variable-name
169 is on of the following:
171 JobId, Client, Pool, Storage, Catalog, MediaType, NumVols, DirName,
172 Level, Type, Job, JobName, JobStatus
174 Bacula varibles can be set using Python keyword arguments:
176 bacula.set(jcr=j, VolumeName="xyz")
178 The two currently implemented writable "variables" are:
180 VolumeName and JobReport
182 It is possible to submit a Bacula run command with the following:
184 bacula.run(j, "run kernsave client=Matou storage=File")
186 this function returns the JobId of the job that was started. If
187 there is an error, the return value is zero.
191 == File EndJob.py ===
195 jobid = bacula.get(j, "JobId")
196 client = bacula.get(j, "Client")
197 bacula.set(jcr=j, JobReport="EndJob output: JobId=%d Client=%s.\n" % (jobid, client))
199 startid = bacula.run(j, "run kernsave")
200 print "Python started jobid=", startid
205 == File NewVolume.py ===
209 jobid = bacula.get(j, "JobId")
210 print "JobId=", jobid
211 client = bacula.get(j, "Client")
212 print "Client=" + client
213 numvol = bacula.get(j, "NumVols");
214 print "NumVols=", numvol
215 bacula.set(jcr=j, JobReport="New Volume set for Job.\n")
216 bacula.set(jcr=j, VolumeName="TestA-001")
