2 Release Notes for Bacula 1.39.28
4 Bacula code: Total files = 442 Total lines = 150,218 (*.h *.c *.in)
7 Version 1.39.28 contains mainly bug fixes to 1.39.26. Please
8 see the ChangeLog for more details.
10 ==== IMPORTANT Encrypted Volume data may be unreadable ====
11 - If you have been using the data encryption feature of 1.39.x, please
12 be aware that certain combinations of encryption and other options
13 with version 1.39.0 through 1.39.26 created Volume data that cannot
14 be restored. We strongly recommend that anyone using encryption
15 carefully review his/her backups and at a minium do a Full backup
16 with 1.39.28 of all encrypted data. Robert Nelson has identified
17 and fixed it as follows:
19 No filters = Works fine
21 Compression = Works fine
22 Encryption = Works fine
23 Sparse + Compression = Works fine
25 Sparse + Encryption = Restore broken
26 Sparse + Compression + Encryption = Restore broken
27 Compression + Encryption = Restore broken
30 All combinations work fine.
32 ==== IMPORTANT a stock SuSE 10.1 kernel may crash =====
33 - A stock SuSE 10.1 kernel may crash when Bacula runs and accesses
34 the tape drive. Workaround, load a Fedora kernel, which works fine,
35 or load the SuSE 10.2 rc5 kernel which also works fine.
37 ==== IMPORTANT Catalog update required =====
38 - The database format has been updated from what was used in
39 Bacula 1.38.x. You must manually update your database before
40 running Bacula 1.39.x or higher. Please backup your previous
41 version of the database before running the update. The update
42 script will be automatically installed in your scripts directory,
43 or can also be found in <bacula-source>/src/cats. It is called:
45 ./update_bacula_tables
47 It is necessary to run it only once the first time you move to
48 a 1.39.x beta or to 1.40.0. Upgrading the Bacula version
49 thereafter does not require updating the database again.
50 Depending on the size of your database the script make take a
51 bit of time, to run, but in general, it should be very fast.
53 ==== IMPORTANT DVD Volume format changed ====
54 - The current Volume format written by 1.39.22 is different from
55 the format written by previous versions. The two formats
56 are not compatible. Thus any DVDs written prior to 1.39.22 will
57 be unreadable by version 1.39.22.
59 ==== IMPORTANT miscellaneous ====
60 - The Gnome console program (gconsole) no longer functions as it
61 should. If you have multiple catalogs, you will need to select
62 the catalog (this I will fix). More importantly, in restore
63 mode, the restore tree is no longer shown in the left pane. I
64 suspect this is due to incompatible changes in the GTK+ API,
65 and hence have given up on gnome and gtk+, as this has already
66 happened several times previously. At some point there
67 will be a new GUI console.
68 - The bacula-dir.conf directive Accept Any Volume has been
69 removed because it was never implemented. You must delete all
70 occurrence of this directive for the Director to run.
71 - The --mandir ./configure option now points to the top level man
72 directory. The man files will be installed under mandir/man8 and
73 mandir/man1 as appropriate.
74 - The "Accept Any Volume" directive has been removed. It was never
75 implemented. Bacula will always accept any valid tape that is in
76 the drive for appending.
77 - You *should* be able to use 1.38.x FDs with version 1.39.18 Director
78 and SD providing you do not use any of the new features (runscript,
79 data encryption). It seems to work here, but we do not guarantee it.
80 - Your Director and SD must be simultaneously upgraded.
81 - The restore command no longer uses the MediaType as the primary method
82 of finding a suitable Storage device. Normally it will select the last
83 device used to write a Volume. If no storage device is defined, it
84 will use the old algorithm which selects the first Storage resource
85 with the correct MediaType.
86 - The MD5/SHA1 hash codes kept in the database are now kept in a binary
87 format compatible with the rest of the world. If you are running verify
88 jobs, you *must* do an InitCatalog or all files will show an MD5
89 difference. Also, authentication uses the new algorithm by
90 default, but *should* accept connections from older components (FD) using
91 the old non-compatible algorithm. This has been tested, but more
92 more testing is still needed.
94 ==== IMPORTANT new Win32 install procedure =====
95 For Win32 migrations from versions prior to 1.39.0 nothing special
96 needs to be done to upgrade. Everything should be taken care of
97 automatically. The only thing not done is to delete the old C:\Bacula
98 directory (mostly out of paranoia, we can change that prior to release if
99 everyone is comfortable with it).
101 Prior to using the current installer, if you used a version of the beta
102 prior to 1.39.26, you must do one of the following three things:
104 1) Uninstall prior beta version and select the option to delete
105 the configuration and state files. This will get rid of the bogus
106 configuration files. Reinstall the new 1.39.26 version.
108 2) Manually copy the *.conf files from C:\Bacula\bin to
109 C:\Documents and Settings\All Users\Application Data\Bacula.
111 3) Manually edit the *.conf files in C:\Documents and
112 Settings\All Users\Application Data\Bacula. The links in the Bacula menu
113 can be used to avoid having to enter that ugly path.
115 After one of these has been done the upgrade should work fine.
117 Major new Features in 1.40.0:
118 - The basic features of Migration are now complete, and
119 are documented in a new Migration chapter in the manual
120 http://www.bacula.org/dev-manual/Migration.html
121 - There is an Encryption chapter in the doc.
122 http://www.bacula.org/dev-manual/Bacula_Data_Encryption.html
123 - Additional support for removable devices. See the
124 Requires Mount, Mount Point, Mount Command, and Unmount
125 Commands in the Storage daemon configuration chapter:
126 http://www.bacula.org/dev-manual/Storage_Daemon_Configuratio.html
127 Also see the Edit Codes for Mount and Unmount Directives in the
129 - Switch the Win32 build from using Microsoft C++ to using mingw32
130 cross-compiling. The initial work was done by Howard Thomson,
131 then tweaked by me. Robert Nelson then totally reworked the
132 cross-compiling code so that it not only cross-compiles, but
133 also compiles on Visual Studio, and at the same time, he added
134 all the current Unix features to the FD, such as selection on
135 drives, encryption support, building *all* the tools, ...
136 - The Director and Storage daemon have now been ported to Win32.
137 This code is working but should still be considered beta (i.e.
138 test carefully before putting into production).
139 - Data encryption done in the Client is now supported due to code
140 submitted by Landon Fuller.
141 - Bacula restore and bextract can now extract non-portable Win32 data to
142 any client (including Unix/Linux clients). Of course, in doing so,
143 the Microsoft specific permissions and ACLs will be lost. Thanks
144 to Thorsten Engel for this code.
145 - The 260 character limitation for Win32 paths name lengths is now
146 eliminated thanks to Thorsten Engel.
147 - Eric Bollengier wrote new RunScript directives that includes
148 the old RunBefore/AfterJob and ClientRunBefore/AfterJob features
149 plus a *lot* more, allowing you to control just about every aspect
150 of running scripts. See the manual for detailed documentation.
151 http://www.bacula.org/dev-manual/Configuring_Director.html#5227
152 - SunOS ACLs should now work thanks to a patch from David Duchscher.
153 - Apply days keyword patch from Alexander.Bergolth at wu-wien.ac.at
154 If this patch is applied, the number of days can be specified with
155 "list nextvol days=xx"
158 This can be used to preview the next scheduled job (and the
159 next tape to be used) on Fridays if there are no scheduled jobs during
161 - Apply patch for enhancing wait from Eric Bollengier. One can now:
162 wait (wait for all jobs to stop)
164 wait jobuid=unique id
166 - Volumes can now be set to Enable, Disable, or Archive. If they
167 are not enabled, Volumes will not be mounted.
168 Implement update volume enable=(on|off|true|false|archived|0|1|2)
169 - Add Catalog message destination in Messages resource that puts the
170 job report in the Log database table.
173 New Features in 1.40.0:
174 - Add enable/disable job=<job-name>. This command prevents
175 the specified job from being scheduled. Even when disabled,
176 the job can be manually started from the console.
177 - The database Id records should be 32/64 bit independent now. 64 bits
178 can be enabled by changing one define, but this has never been tested.
179 - Relative path specifications (i.e. ../xxx) are now permitted in
180 the restore cd command.
181 - When running multiple simultaneous jobs, most jobs that use spooling
182 will now finish faster due to a mutex optimization made by Eric
184 - Conf files containing UTF-8 marker at the head of the file as well as
185 conf files containing Window cr/lf and Mac cr line termination characters
186 are now accepted thanks to Robert Nelson.
187 - Windows tray status windows are scrollable and resizable.
188 - Win32 external script execution is much more flexible -- handles
189 spaces in names better, ...
190 - Lots of DVD fixes -- writing DVDs is now reported to work.
191 - Fix opening of database in a restricted console to respect
193 - Permit multiple console/director resources in bconsole.conf.
194 patch from Carsten Paeth calle@calle.in-berlin.de
195 - Character substitution in Job/JobDefs WriteBootStrap.
196 from Eric Bollengier.
197 - Apply patch supplied in bug #656 to pass priority field
198 in the run dialog to the Director in gnome console.
199 - Add support of encrypted data stream to bscan from Eric.
200 display data_len instead of data content (may be binary).
201 - Add Enabled=xxx on update slots command.
202 - Add host:port to connect failure messages to FD and SD from Dir/
203 - Add WhereACL to console ACL list. If nothing is specified, only
204 the default is permitted for restore. Otherwise, *all* allows any
205 path, or you can specify permitted paths. This should allow control
206 over where users can restore files. This is untested.
207 - Install man pages with 'make install'.
208 - Add Media.Enabled flag to client backups for dotcmds.c
209 - Enforce Media.Enabled=1 for a current restore to work
210 - Require restore case 3 to have sqlquery permission to work.
211 - Add -n option to bconsole to turn off conio.
212 - The bytes field in the terminated jobs part of the status
213 command now reports in KB, MB, ... units.
214 - When not descending into a directory, print the File= name that
215 triggered it -- makes why not descending a bit clearer
216 - Do not unload autochanger when doing "update slots"
217 - Implement mount command for autochanger
218 - Fix bug #462 incorrect error message printed when client script called
219 from File= was not found.
220 - Fix bug #558 (waiting for feedback) where Bacula needs too much time to
221 do a rewind on Solaris when no tape is in the drive (Solaris does not
222 have the detailed errno found on Linux). Added Solaris specific code.
223 Note, this may apply to other OSes as well.
224 - The examples directory has a new bacula_mail_summary.sh file that
225 creates a single email summary of any number of jobs. Submitted by
227 - Add nagios plugin to the examples directory. Submitted by
229 - Modify most restore error messages to be queued so that they
230 appear at the end of the job rather than mixed with the restore
231 listing where they could be "lost".
232 - Apply patch supplied by user (slightly modified) to fix
233 correct detection of holes in block devices and FIFOs.
235 - Added a report.pl program to the examples directory from Jonas Bjorklund.
236 - Add two new queries to query.sql provided by Arno. One
237 list volumes known to the Storage device, and the other
238 lists volumes possibly needing replacement (error, ...).
239 - Implement new code for changing userid and group at startup. This
240 should get Bacula into the correct groups.
241 - Implement support for removable filesystems.
242 - Transfer rates are now presented in a more readable format thanks
243 to a user submission.
244 - SD is now aware of what volumes are mounted. More information is printed
245 in the Status report.
246 - The Pool Maximum Volumes directive is now respected in all places.
247 - A Storage device can now be specified in a Pool resource. It will override
248 all other Storage specifications.
249 - Most but not all directives accept true/false in place of yes/no.
250 - A patch from Karl Hakimian that reads JobIds, FileIndexes
251 from a database table for restore.
252 - There are a number of new tables. Some such as the Location table are
253 designed for user use in doing Volume Management software.
254 - Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to
255 accept time qualifiers.
256 - Implement jobuid to replace old usage of job in keywords as
257 suggested by Eric Bollengier.
258 - Implement write variables for Python to set Priority (anytime), and
259 Job Level, only during JobInit event.
260 - Use the keyword ujobid to mean the unique job id; job or jobname
261 to mean the Job name given on the Name directive, and jobid to
262 be the numeric (non-unique) job id.
263 - Allow the SD to use multiple drives during a backup/restore (only
264 one at a time). This is not well tested.
265 - Integrate addition of line count limitation to bsmtp -l from
266 Sebastian Stark <stark at tuebingen.mpg.de>
267 - Split the bacula start/start script into four files:
268 bacula -- starts and stops calling other scripts
269 bacula-ctl-dir -- starts/stops the director
270 bacula-ctl-fd -- starts/stops the File daemon
271 bacula-ctl-sd -- starts/stops the Storage daemon
272 - Remove automatic case folding on Windows FDs. You must
273 explicitly use the 'Ignore Case = yes' option.
274 - Implement wild program in tools directory for testing
275 wild-cards. Almost identical to the regex program.
276 - Use the new bregex.c to implement Regex expressions on Win32.
277 - Apply patch from Christopher Hull
278 - Allow multiple connections to database with different
280 - Invalidate the scheduler when doing a reload. Fixes seg
281 fault, but still 60 second window.
282 - Additional info in Reschedule message.
283 - Use set_jcr_job_status() everywhere to prevent loss of
285 - Display peer IP in FD if error from connecting DIR.
286 - Don't increment file count for DIRBEGIN.
287 - Replace illegal characters in Win32 filename by _.
288 - Add SE_CREATE_PERMANENT_NAME privilege in Win32.
289 - Hash hard link filenames rather than linked list (performance).
290 - Fix for security failure in chdir on Win32.
291 - Add CreateDirectoryA/W win32 API entry points.
292 - programs to duplicate Bacula's base64 algorithm using standard
293 routines. This fixes bugs #296, and 565. Patch submitted by
295 - Fixes to reloading the Dir conf file from Eric Bollengier and Christopher
297 - Modify LICENSE to correct some problems pointed out by Debian.
298 - Apply a patch submitted by cesarb in bug #606 to implement O_NOATIME support.
299 O_NOATIME is a open() flag which makes it possible to read a file without
300 updating the inode atime (and also without the inode ctime update which
301 happens if you try to set the atime back to its previous value). It also
302 prevents a race condition when two programs are reading the same file, but
303 only one does not want to change the atime. It's most useful for backup
304 programs and file integrity checkers (and bacula can fit on both
306 You enable it in the Bacula FileSet Options resource by setting:
308 The effect of this option is similar to the keepatime option except
309 it is more efficient and avoids modifying ctime.
310 - Implement a pile of new man pages contributed by Jose Tallon.
311 - Implement a number of user supplied patches for DVD writing.
312 - Modify the database format for handling Migration jobs:
313 Add PriorJobId, RealEndTime to Job table
315 Remove Stripe from JobMedia record (not used, wasting space)
316 Add ScratchPoolId, RecyclePoolId, Enabled to Media record
317 Add Cost to Location table.
318 Enabled to Media table and Location table.
319 - Security: harden authentication failure in FD by single threading errors
320 and forcing a 6 second wait.
321 - If using GCC (actually g++) add the following compiler flags
322 -fno-strict-aliasing -fno-exceptions -fno-rtti
323 - Turn on new bsnprintf() code.
324 The reason for this code is to eliminate the
325 security problems associated with using the system libraries
327 - Implement job report that indicates where Storage and Pool
328 came from -- with overrides and Pool storage and NextPool,
329 it is all very complicated.
330 - Add more detail (Storage, Device) to list of volumes printed
332 - Add new VOLMGMT message class. No messages are yet sent with this
334 - Spend a lot of time integrating mkcdrec with the rescue disk.
335 - Add spooling/despooling info in status output of SD.
336 - Add Comment field to llist of a volume.
337 - Allow true/false in some yes/no questions.
339 Additional Features Added for Win32:
340 - Added DriveType directive to the Director's Include Option FileSet
341 resource. Allowed values are: fixed, removable, cdrom, and remote. There
342 is only an implementation for Windows because it is the only platform that
343 has the concept of drives.
345 - Adds EnhancedWild directive to the Director's Include Option FileSet
346 resource. Allowed values are: yes and no.
348 When EnhancedWild is enabled then the processing of the
349 Wild, WildDir and WildFile is changed in the following ways.
351 Patterns conform to Posix
352 \ is not a special character in character classification []
353 To match a - it must be the first or last character
354 To match a ] it must be the first character
356 fnmatch option FNM_FILE_NAME is specified * doesn't match a /
357 so it won't match multiple directory levels in a path
359 - Relative WildFile patterns (ones without a leading /) match
360 against the filename portion. This in combination with the
361 FNM_FILE_NAME fnmatch() flag makes directives such as WildFile =
362 abc*.def work as expected.
364 - Adds support for the shell's feature of brace expansion.
366 Here is an example where braces allow 24 lines to be expressed in 5.
368 # Exclude directories full of lots and lots of useless little files
369 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Cookies"
370 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Recent"
371 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/History"
372 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temp"
373 WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temporary Internet Files"
