8 - This is mainly a bug release fix. In addition, the multiple drive
9 reservation algorithm has been rewritten.
10 - Implement load balancing code.
11 - Rewrite reservation algorithm again. Rename variables to be
12 more logical, add HEARTBEAT with Director, allow cancel of
13 jobs stuck in reservation, add last resourt any_drive.
14 - Fix seg fault if user labels a drive directly bug #513
15 - Remove quotes around Version as it breaks things.
16 - Merge in Aleksandar Milivojevic's mods to the spec file.
17 - Apply sparse code fix for raw drives and fifos. Bug 506
18 - Thorsten fixed Unicode cd problem with wx-console bug 505.
19 - Correct reservation system to do a last ditch try
20 for any mounted volume, then anyone anywhere.
21 - Updates to ssh-tunnel from Joshua Kugler.
22 - Added a report.pl program from Jonas Bjorklund.
23 - Simplify the O_NONBLOCK open() code for tape drives,
24 and always open nonblocking.
25 - Do not wait for open() if EIO returned (shouldn't happen).
26 - Eliminate 3 argument to tape open().
27 - Correct the slot # edited in the 3995 Bad autochanger unload
29 - With -S on bscan (show progress) do not divide by zero.

116 - AMD64 users see compiler bug warning below!!!!!!!!!
118 Major Changes in 1.38:
119 - Fixed out of order Volumes in restore.
120 - Improved algorithm for reserving drives in multiple drive
121 autochangers. Autochange users MUST use the new Autochanger
122 resource in the Storage daemon.
123 - There is a new database format that is not compatible
124 with previous databases. You must upgrade if converting
125 from 1.36.x. No changes from version 1.37.30.
126 - The Director, Storage daemon, and File daemons are
127 Deamons are not compatible with prior versions.
128 All FDs must be upgraded at the same time.
129 - Support for ANSI/IBM labels.
130 - Faster database inserts due to combining the MD5/SHA1 into
131 the attributes record, eliminating one INSERT/file backed up.
132 - Python Event support has been added. See below for
133 configuration and details. The implementation is somewhat minimal,
134 so the functionality is not complete. The Python interface
135 has not been extensively tested, so please consider it BETA.
136 - DVD writing support, using parts, and some new directives in
137 the Device resource of the Storage configuration file thanks
138 to Nicolas Boichat. Please note that this code is still
139 BETA and should be carefully tested before using in
141 - Seven new options keywords in a FileSet resource:
142 ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
143 and regexfile thanks to Pruben Guldberg). See below for details.
144 - Restore of all files for a Job or set of jobs even if the file
145 records have been removed from the catalog.
146 - Restore of a directory (non-recursive, i.e. only one level).
147 - Support for TLS (ssl) between all the daemon connections thanks
149 - Any Volume in the Pool named Scratch may be reassigned to any
150 other Pool when a new Volume is needed.
151 - You may clone a Job and thus write (almost) the same data
152 to multiple Volumes simultaneously (see below). Actually,
153 any Job may start any other Job with this mechanism, so it
154 also be used to group jobs.
155 - Unicode filename support for Win32 (thanks to Thorsten Engel)
156 - Volume Shadow Copy support for Win32 thus the capability to
157 backup exclusively opened files (thanks to Thorsten Engel).
158 A VSS enabled Win32 FD is available. You must explicitly
159 turn on VSS with "Enable VSS = yes" in your FileSet resource.
160 - New manual format with an index (thanks to Karl Cunningham).
161 - New Web site format (thanks to Michael Scherer).
163 - Web-bacula, previously a separate project by Juan Luis Frances,
164 is now included in the Bacula GUI release. This is a management
165 level tool for reporting the state of Bacula jobs.
166 - The code is now Internationalized so that it can be localized
167 in native languages. Thanks to Nicolas Boichat.
170 - New Job directive "Prefer Mounted Volumes = yes|no" causes the
171 SD to select either an Autochanger or a drive with a valid
172 Volume already mounted in preference. If none is available,
173 it will select the first available drive.
174 - New Run directive in Job resource of DIR. It permits
175 cloning of jobs. To clone a copy of the current job, use
176 Run = "job-name level=%l since=\"%s\""
177 Note, job-name is normally the same name as the job that
178 is running but there is no restriction on what you put. If you
179 want to start the job by hand and use job overrides such as
180 storage=xxx, realize that the job will be started with the
181 default storage values not the overrides. The level=%l guarantees
182 that the chosen level of the job is the same, and the since=...
183 ensures that the job uses *exactly* the same time/date for incremental
184 and differential jobs. The since=... is ignored when level=Full.
185 A cloned job will not start additional clones, so it is not possible
187 - New Options keywords in a FileSet directive (backported to 1.36.3):
189 Will do a wild card match against directories (files will not
192 Will do a wild card match against files (directories will not
195 Will do a regular expression match against directories (files
196 will not be matched).
198 Will do a regular expression match against files( directories
199 will not be matched).
200 - IgnoreCase = yes | no
201 Will ignore case in wild card and regular expression matches.
202 This is handy for Windows where filename case is not significant.
204 where string is a filesystem type: ext2, jfs, ntfs, proc,
205 reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660. For ext3
206 systems, use ext2. You may have multiple fstype directives
207 and thus permit multiple filesystem types. If the type
208 specified on the fstype directive does not match the
209 filesystem for a particular directive, that directory will
210 not be backed up. This directive can be used to prevent
211 backing up non-local filesystems.
212 - HFS Plus Support = yes | no
213 If set, Mac OS X resource forks will be saved and restored.
214 - Label Type = ANSI | IBM | Bacula
215 Implemented in Director Pool resource and in SD Device resource.
216 If it is specified in the SD Device resource, it will take
217 precedence over the value passed from the Director to the SD.
218 - Check Labels = yes | no
219 Implemented in the SD Device resource. If you intend to read
220 ANSI or IBM labels, this *must* be set. Even if the volume
221 is not ANSI labeled, you can set this to yes, and Bacula will
222 check the label type.
223 - Scripts Directory = <directory> name. Defines the directory from
224 which Bacula scripts will be called for events. In fact, Bacula
225 appends this name to the standard Python list of search directories,
226 so the script could also be in any of the Python system directories.
227 - In FileSet, you can exclude backing up of hardlinks (if you have
228 a lot, it can be very expensive), by using:
230 in the Options section. Patch supplied by David R Bosso. Thanks.
231 - MaximumPartSize = bytes (SD, Device resource)
232 Defines the maximum part size.
233 - Requires Mount = Yes/No (SD, Device resource)
234 Defines if the device require to be mounted to be read, and if it
235 must be written in a special way. If it set, the following directives
236 must be defined in the same Device resource:
237 + Mount Point = directory
238 Directory where the device must be mounted.
239 + Mount Command = name-string
240 Command that must be executed to mount the device. Before the command
241 is executed, %a is replaced with the Archive Device, and %m with the
243 + Unmount Command = name-string
244 Command that must be executed to unmount the device. Before the
245 command is executed, %a is replaced with the Archive Device, and
246 %m with the Mount Point.
247 + Write Part Command = name-string
248 Command that must be executed to write a part to the device. Before
249 the command is executed, %a is replaced with the Archive Device, %m
250 with the Mount Point, %n with the current part number (0-based),
251 and %v with the current part filename.
252 + Free Space Command = name-string
253 Command that must be executed to check how much free space is left
254 on the device. Before the command is executed, %a is replaced with
255 the Archive Device, %m with the Mount Point, %n with the current part
256 number (0-based), and %v with the current part filename.
257 - Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource)
258 If this directive is set to yes (default no), a new part file will be
259 created after the job is finished.
260 - A pile of new Directives to support TLS. Please see the TLS chapter
264 - "python restart" restarts the Python interpreter. Rather brutal, make
265 sure no Python scripts are running. This permits you to change
266 a Python script and get Bacula to use the new script.
268 New configure options:
269 - --with-libintl-prefix for defining alternate locations for
270 the NLS internationalization libraries. Not normally required.
271 - --datadir for defining where the language files will be installed
272 required only if you do not want the default /usr/share.
275 - If you use an Autochanger, you MUST update your SD conf file
276 to use the new Autochanger resource. Otherwise, certain commands
277 such as "update slots" may not work.
278 - You must add --with-python=[DIR] to the configure command line
279 if you want Python support. Python 2.2, 2.3 and 2.4 should be
280 automatically detected if in the standard place.
281 - When linking with --with-python, there are a few warnings that
283 - You must either create a new catalog database or upgrade your
284 old database. After installation, run from your scripts
287 ./upgrade_bacula_tables
289 You can also find this script in the <bacula-source>/src/cats
291 - The Director, Storage daemon, and File daemons are
292 Deamons are not compatible with prior versions.
293 All FDs must be upgraded at the same time.
294 - You must add --with-openssl to the configure command line if
295 you want TLS communications encryption support.
296 - Disk seeking during restores does not yet work correctly in
297 all cases, so it is turned off.
298 - Note, with gcc (GCC) 4.0.1 20050727 (Red Hat 4.0.1-5) on an
299 AMD64 CPU running 64 bit CentOS4, there is a compiler bug that
300 generates bad code that causes Bacula to segment fault.
301 Typically you will see this in the Storage daemon first. The
302 solution is to compile Bacula ensuring that no optimization is
303 turned on (normally it is -O2).
304 This same compiler bug has been reported and confirmed with
305 gcc (GCC) 4.0.2 20050901 (prerelease) (SUSE Linux) running on
306 an AMD64 CPU. This for the moment, I would recommend that all
307 users of GCC 4.0.1 or greater turn off all optimization when
312 - Security fixes for temp files created in mtx-changer, during
313 ./configure, and during making of Rescue disk.
314 - A new script, dvd-handler, in the scripts directory,
315 which is designed to be used as parameters to Write Part Command and
316 Free Space Command. They need the dvd+rw-tools to be installed
317 (http://fy.chalmers.se/~appro/linux/DVD+RW/) AND, the growisofs
318 program must be patched using the
319 <bacula-source>/patches/dvd+rw-tools-5.21.4.10.8.bacula.patch
320 You must have Python installed to run the scripts.
321 - Part files support: File volumes can now be split into multiple
322 files, called "parts".
323 - For the details of the Python scripting support, please see the new
324 Python Scripting chapter in the manual.
