2 Release Notes for Bacula 2.0.0
4 Bacula code: Total files = 438 Total lines = 154,329 (*.h *.c *.in)
6 ==== IMPORTANT Catalog update required =====
7 - The database format has been updated from what was used in
8 Bacula 1.38.x. You must manually update your database before
9 running Bacula 1.39.x or higher. If you are using Bacula supplied
10 RPMs this is not necessary as the RPM does it automatically.
11 Please backup your previous version of the database before
12 running the update. The update script will be automatically
13 installed in your scripts directory, or can also be found in
14 <bacula-source>/src/cats. It is called:
16 ./update_bacula_tables
18 It is necessary to run it only once the first time you move to
19 a 2.0.0. Upgrading the Bacula version thereafter does not
20 require updating the database again. Depending on the size of
21 your database the script make take a bit of time, to run, but
22 in general, it should be very fast.
24 ==== IMPORTANT new Win32 install procedure =====
25 For Win32 migrations from versions prior to 1.39.0 nothing special
26 needs to be done to upgrade. Everything should be taken care of
27 automatically. The only thing not done is to delete the old C:\bacula
28 directory mostly out of paranoia.
30 ==== IMPORTANT miscellaneous ====
31 - The Gnome console program (gconsole) no longer functions as it
32 should.More importantly, in restore mode, the restore tree is
33 no longer shown in the left pane. I suspect this is due to
34 incompatible changes in the GTK+ API, and hence have given up
35 on gnome and gtk+, as this has already happened several times
36 previously. At some point there will be a new GUI console.
37 - The bacula-dir.conf directive Accept Any Volume has been
38 removed because it was never implemented. You must delete all
39 occurrence of this directive for the Director to run. The Storage
40 daemon will automatically accept any valid Volume that you mount.
41 - The --mandir ./configure option now points to the top level man
42 directory. The man files will be installed under mandir/man8 and
43 mandir/man1 as appropriate.
44 - You *should* be able to use 1.38.x FDs with version 2.0.0 Director
45 and SD providing you do not use any of the new features (runscript,
46 data encryption). It seems to work here, but we do not guarantee it.
47 - Your Director and SD must be simultaneously upgraded.
48 - The restore command no longer uses the MediaType as the primary method
49 of finding a suitable Storage device. Normally it will select the last
50 device used to write a Volume. If no storage device is defined, it
51 will use the old algorithm which selects the first Storage resource
52 with the correct MediaType.
53 - The MD5/SHA1 hash codes kept in the database are now kept in a binary
54 format compatible with the rest of the world. If you are running verify
55 jobs, you *must* do an InitCatalog or all files will show an MD5
56 difference. Also, authentication uses the new algorithm by
57 default, but *should* accept connections from older components (FD) using
58 the old non-compatible algorithm. This has been tested, but more
59 more testing is still needed.
60 - A stock SuSE 10.1 kernel may crash when Bacula runs and accesses
61 the tape drive. Workaround, load the SuSE 10.1 version 2.6.16.21-0.25
62 kernel or later. The SuSE 10.2 Alpha 5 or later kernel also works.
63 This problem may also be present in certain Fedora FC5 kernels.
64 - If you have been using the data encryption feature of 1.39.x, please
65 be aware that certain combinations of encryption and other options
66 with version 1.39.0 through 1.39.26 created Volume data that cannot
67 be restored. We strongly recommend that anyone using encryption
68 carefully review his/her backups and at a minium do a Full backup
69 with 1.39.28 of all encrypted data. Robert Nelson has identified
70 and fixed it as follows:
72 No filters = Works fine
74 Compression = Works fine
75 Encryption = Works fine
76 Sparse + Compression = Works fine
78 Sparse + Encryption = Restore broken
79 Sparse + Compression + Encryption = Restore broken
80 Compression + Encryption = Restore broken
83 Most combinations work, but some encrypted files are
84 not properly restored.
87 All combinations work fine except Sparse+Encryption.
89 Bottom line, if you are using data encryption, please test restoring
90 data to be sure it all works correctly.
91 - The current Volume format written by 1.39.22 is different from
92 the format written by previous versions. The two formats
93 are not compatible. Thus any DVDs written prior to 1.39.22 will
94 be unreadable by version 1.39.22.
95 - If you previously run a Bacula version prior to 1.39.30, the JobMedia
96 data may not be correct for disk Volumes. This can cause incorrect
97 seeking in versions after 1.39.30. If you experience what appears to
98 be data I/O or integrity errors during restores, please add the
99 following directive to your disk DEVICE resource in the Storage
102 Block Positioning = no
104 This will turn off all seek requests during restores and avoid
106 - VSS for Windows clients is now enabled by default.
107 - Do not unload autochanger when doing "update slots"
108 - Implement mount command for autochanger, see manual.
110 New Features in 2.0.0:
111 - Turn on disk seek code for restores.
112 - There is a partial but reasonable translation of the Bacula
113 messages for French. To install it, first configure and build
114 Bacula, then as root run:
116 cd <bacula-source>/po
119 If you have your locale set properly you will get the translated
121 - Bacula now support Migration jobs that are documented in a new
122 Migration chapter in the manual
123 http://www.bacula.org/dev-manual/Migration.html
124 - Data encryption is now implemented and is documented in
125 a new chapter of the manual at:
126 http://www.bacula.org/dev-manual/Bacula_Data_Encryption.html
127 - Additional support for removable devices. See the
128 Requires Mount, Mount Point, Mount Command, and Unmount
129 Commands in the Storage daemon configuration chapter:
130 http://www.bacula.org/dev-manual/Storage_Daemon_Configuratio.html
131 Also see the Edit Codes for Mount and Unmount Directives in the
133 - Switch the Win32 build from using Microsoft C++ to using mingw32
134 cross-compiling. The initial work was done by Howard Thomson,
135 then tweaked by me. Robert Nelson then totally reworked the
136 cross-compiling code so that it not only cross-compiles, but
137 also compiles on Visual Studio, and at the same time, he added
138 all the current Unix features to the FD, such as selection on
139 drives, encryption support, building *all* the tools, ...
140 - The Director and Storage daemon have now been ported to Win32.
141 This code is working but should still be tested carefully
142 before putting into production.
143 - Bacula restore and bextract can now extract non-portable Win32 data to
144 any client (including Unix/Linux clients). Of course, in doing so,
145 the Microsoft specific permissions and ACLs will be lost. Thanks
146 to Thorsten Engel for this code.
147 - The 260 character limitation for Win32 paths name lengths is now
148 eliminated thanks to Thorsten Engel. However, if you are using
149 Volume Shadow Copy, please be careful to specify all the paths
150 in the bacula-fd.conf file using a full path notation including
152 - Eric Bollengier wrote new RunScript directives that includes
153 the old RunBefore/AfterJob and ClientRunBefore/AfterJob features
154 plus a *lot* more, allowing you to control just about every aspect
155 of running scripts. See the manual for detailed documentation.
156 http://www.bacula.org/dev-manual/Configuring_Director.html#5227
157 - SunOS ACLs should now work thanks to a patch from David Duchscher.
158 - Apply days keyword patch from Alexander.Bergolth at wu-wien.ac.at
159 If this patch is applied, the number of days can be specified with
160 "list nextvol days=xx"
163 This can be used to preview the next scheduled job (and the
164 next tape to be used) on Fridays if there are no scheduled jobs during
166 - From Eric Bollengier. One can now using the bconsole wait command do:
167 wait (wait for all jobs to stop)
169 wait jobuid=unique id
171 - Volumes can now be set to Enable, Disable, or Archive. If they
172 are not enabled, Volumes will not be mounted.
173 Implement update volume enable=(on|off|true|false|archived|0|1|2)
174 - Add Catalog message destination in Messages resource that puts the
175 job report in the Log database table.
176 - Writing/reading DVD Volumes is much more stable -- to the point
177 of being useful. Thanks to Richard Mortimer.
178 - Add enable/disable job=<job-name>. This command prevents
179 the specified job from being scheduled. Even when disabled,
180 the job can be manually started from the console.
181 - The database Id records should be 32/64 bit independent now. 64 bits
182 can be enabled by changing one define and changing the appropriate
183 table variable. Normally, you need 64 bits only for FileId.
184 - Relative path specifications (i.e. ../xxx) are now permitted in
185 the restore cd command.
186 - When running multiple simultaneous jobs, most jobs that use spooling
187 will now finish faster due to a mutex optimization made by Eric
189 - Conf files containing UTF-8 marker at the head of the file as well as
190 conf files containing Window cr/lf and Mac cr line termination characters
191 are now accepted thanks to Robert Nelson.
192 - Windows tray status windows are scrollable and resizable.
193 - Win32 external script execution is much more flexible -- handles
194 spaces in names better, ...
195 - Lots of DVD fixes -- writing DVDs is now reported to work.
196 - Fix opening of database in a restricted console to respect
198 - Much better automatic handling of multiple database catalogs in
200 - Permit multiple console/director resources in bconsole.conf.
201 patch from Carsten Paeth calle@calle.in-berlin.de
202 - Character substitution in Job/JobDefs WriteBootStrap.
203 from Eric Bollengier.
204 - Apply patch supplied in bug #656 to pass priority field
205 in the run dialog to the Director in gnome console.
206 - Add support of encrypted data stream to bscan from Eric.
207 display data_len instead of data content (may be binary).
208 - Add Enabled=xxx on update slots command.
209 - Add host:port to connect failure messages to FD and SD from Dir/
210 - Add WhereACL to console ACL list. If nothing is specified, only
211 the default is permitted for restore. Otherwise, *all* allows any
212 path, or you can specify permitted paths. This should allow control
213 over where users can restore files. This is untested.
214 - Install man pages with 'make install'.
215 - Add Media.Enabled flag to client backups for dotcmds.c
216 - Enforce Media.Enabled=1 for a current restore to work
217 - Require restore case 3 to have sqlquery permission to work.
218 - Add -n option to bconsole to turn off conio -- used in bweb.
219 - The bytes field in the terminated jobs part of the status
220 command now reports in KB, MB, ... units.
221 - When not descending into a directory, print the File= name that
222 triggered it -- makes why not descending a bit clearer
223 - Do not unload autochanger when doing "update slots"
224 - Implement mount command for autochanger
225 - Fix bug #462 incorrect error message printed when client script called
226 from File= was not found.
227 - Fix bug #558 (waiting for feedback) where Bacula needs too much time to
228 do a rewind on Solaris when no tape is in the drive (Solaris does not
229 have the detailed errno found on Linux). Added Solaris specific code.
230 Note, this may apply to other OSes as well.
231 - The examples directory has a new bacula_mail_summary.sh file that
232 creates a single email summary of any number of jobs. Submitted by
234 - Add nagios plugin to the examples directory. Submitted by
236 - Modify most restore error messages to be queued so that they
237 appear at the end of the job rather than mixed with the restore
238 listing where they could be "lost".
239 - Apply patch supplied by user (slightly modified) to fix
240 correct detection of holes in block devices and FIFOs.
242 - Added a report.pl program to the examples directory from Jonas Bjorklund.
243 - Add two new queries to query.sql provided by Arno. One
244 list volumes known to the Storage device, and the other
245 lists volumes possibly needing replacement (error, ...).
246 - Implement new code for changing userid and group at startup. This
247 should get Bacula into the correct groups.
248 - Implement support for removable filesystems -- device type directive
249 and mount, unmount directives.
250 - Transfer rates are now presented in a more readable format thanks
251 to a user submission.
252 - SD is now aware of what volumes are mounted. More information is printed
253 in the Status report. You must take much more care now to unmount
254 devices prior to removing tapes that Bacula has open or prior to
255 changing a magazine. Don't forget to do a mount afterwards or the
256 device will be blocked.
257 - The Pool Maximum Volumes directive is now respected in all places.
258 - A Storage device can now be specified in a Pool resource. It will override
259 all other Storage specifications.
260 - Most but not all directives accept true/false in place of yes/no.
261 - A patch from Karl Hakimian that reads JobIds, FileIndexes
262 from a database table for restore.
263 - There are a number of new tables. Some such as the Location table are
264 designed for user use in doing Volume Management software.
265 - Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to
266 accept time qualifiers.
267 - Implement jobuid to replace old usage of job in keywords as
268 suggested by Eric Bollengier.
269 - Implement write variables for Python to set Priority (anytime), and
270 Job Level, only during JobInit event.
271 - Use the keyword ujobid to mean the unique job id; job or jobname
272 to mean the Job name given on the Name directive, and jobid to
273 be the numeric (non-unique) job id.
274 - Allow the SD to use multiple drives during a backup/restore (only
276 - Integrate addition of line count limitation to bsmtp -l from
277 Sebastian Stark <stark at tuebingen.mpg.de>
278 - Split the bacula start/start script into four files:
279 bacula -- starts and stops calling other scripts
280 bacula-ctl-dir -- starts/stops the director
281 bacula-ctl-fd -- starts/stops the File daemon
282 bacula-ctl-sd -- starts/stops the Storage daemon
283 - Remove automatic case folding on Windows FDs. You must
284 explicitly use the 'Ignore Case = yes' option.
285 - Implement wild program in tools directory for testing
286 wild-cards. Almost identical to the regex program.
287 - Use the new bregex.c to implement Regex expressions on Win32.
288 - Apply patch from Christopher Hull
289 - Allow multiple connections to database with different
291 - Invalidate the scheduler when doing a reload. Fixes seg
292 fault, but still 60 second window.
293 - Additional info in Reschedule message.
294 - Use set_jcr_job_status() everywhere to prevent loss of
296 - Display peer IP in FD if error from connecting DIR.
297 - Don't increment file count for DIRBEGIN.
298 - Replace illegal characters in Win32 filename by _.
299 - Add SE_CREATE_PERMANENT_NAME privilege in Win32.
300 - Hash hard link filenames rather than linked list (performance).
301 - Fix for security failure in chdir on Win32.
302 - Add CreateDirectoryA/W win32 API entry points.
303 - programs to duplicate Bacula's base64 algorithm using standard
304 routines. This fixes bugs #296, and 565. Patch submitted by
306 - Fixes to reloading the Dir conf file from Eric Bollengier and Christopher
308 - Modify LICENSE to correct some problems pointed out by Debian.
309 - Apply a patch submitted by cesarb in bug #606 to implement O_NOATIME support.
310 O_NOATIME is a open() flag which makes it possible to read a file without
311 updating the inode atime (and also without the inode ctime update which
312 happens if you try to set the atime back to its previous value). It also
313 prevents a race condition when two programs are reading the same file, but
314 only one does not want to change the atime. It's most useful for backup
315 programs and file integrity checkers (and bacula can fit on both
317 You enable it in the Bacula FileSet Options resource by setting:
319 The effect of this option is similar to the keepatime option except
320 it is more efficient and avoids modifying ctime.
321 - Implement a pile of new man pages contributed by Jose Tallon.
322 - Modify the database format for handling Migration jobs:
323 Add PriorJobId, RealEndTime to Job table
325 Remove Stripe from JobMedia record (not used, wasting space)
326 Add ScratchPoolId, RecyclePoolId, Enabled to Media record
327 Add Cost to Location table.
328 Enabled to Media table and Location table.
329 - Security: harden authentication failure in FD by single threading errors
330 and forcing a 6 second wait.
331 - If using GCC (actually g++) add the following compiler flags
332 -fno-strict-aliasing -fno-exceptions -fno-rtti
333 - Turn on new bsnprintf() code. The reason for this code is to
334 eliminate the security problems associated with using the
335 system libraries print routines.
336 - Implement job report that indicates where Storage and Pool
337 came from -- with overrides and Pool storage and NextPool,
338 it is all very complicated.
339 - Add more detail (Storage, Device) to list of volumes printed
341 - Add new VOLMGMT message class. No messages are yet sent with this
343 - Improved Bacula rescue procedures -- see the Disaster Recovery
344 chapter of the manual
345 - Add spooling/despooling info in status output of SD.
346 - Add Comment field to llist of a volume.
347 - Allow true/false in many but not all yes/no directives.
348 - The Bacula source code is now copyrighted by the Free Software
349 Foundation Europe. The Developer's Guide documents the new procedures,
350 and the LICENSE file has been updated.
351 - Apply Jaime Ventura's patch that implements the Messages resource
352 Mail On Success directive.
353 - The Client returns its Version string, which is printed in the Job
355 - The Client returns whether or not VSS and Encryption are used, which
356 are printed in the Job report.
358 Additional Features Added for Win32:
359 - Added DriveType directive to the Director's Include Option FileSet
360 resource. Allowed values are: fixed, removable, cdrom, and remote. There
361 is only an implementation for Windows because it is the only platform that
362 has the concept of drives.
364 - Adds EnhancedWild directive to the Director's Include Option FileSet
365 resource. Allowed values are: yes and no.
367 When EnhancedWild is enabled then the processing of the
368 Wild, WildDir and WildFile is changed in the following ways.
370 Patterns conform to Posix
371 \ is not a special character in character classification []
372 To match a - it must be the first or last character
373 To match a ] it must be the first character
375 fnmatch option FNM_FILE_NAME is specified * doesn't match a /
376 so it won't match multiple directory levels in a path
378 - Relative WildFile patterns (ones without a leading /) match
379 against the filename portion. This in combination with the
380 FNM_FILE_NAME fnmatch() flag makes directives such as WildFile =
381 abc*.def work as expected.
383 - Adds support for the shell's feature of brace expansion.
385 Here is an example where braces allow 24 lines to be expressed in 5.
387 # Exclude directories full of lots and lots of useless little files
388 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Cookies"
389 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Recent"
390 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/History"
391 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temp"
392 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temporary Internet Files"
