14 - %d and %v only valid on Director, not for ClientRunBefore/After.
15 - During tests with the 260 char fix code, I found one problem:
16 if the system "sees" a long path once, it seems to forget it's
17 working drive (e.g. c:\), which will lead to a problem during
18 the next job (create bootstrap file will fail). Here is the
19 workaround: specify absolute working and pid directory in
20 bacula-fd.conf (e.g. c:\bacula\working instead of
22 - Document techniques for restoring large numbers of files.

62 Extract capability (#25)
63 Continued enhancement of bweb
64 Threshold triggered migration jobs (not currently in list, but will be
66 Client triggered backups
67 Complete rework of the scheduling system (not in list)
68 Performance and usage instrumentation (not in list)
69 See email of 21Aug2007 for details.
70 - Look at: http://tech.groups.yahoo.com/group/cfg2html
71 and http://www.openeyet.nl/scc/ for managing customer changes
75 - Why no error message if restore has no permission on the where
77 - Possibly allow manual "purge" to purge a Volume that has not
78 yet been written (even if FirstWritten time is zero) see ua_purge.c
80 - Add disk block detection bsr code (make it work).
82 - Add blast attributes to DIR to SD.
83 - Detect deadlocks in reservations.
85 - Add list during dump
86 - Add in plugin code flag
87 - Add bRC_EndJob -- stops more calls to plugin this job
88 - Add bRC_Term (unload plugin)
89 - remove time_t from Jmsg and use utime_t?
91 - Deadlock detection, watchdog sees if counter advances when jobs are
92 running. With debug on, can do a "status" command.
93 - User options for plugins.
94 - Pool Storage override precidence over command line.
95 - Autolabel only if Volume catalog information indicates tape not
96 written. This will avoid overwriting a tape that gets an I/O
97 error on reading the volume label.
98 - I/O error, SD thinks it is not the right Volume, should check slot
99 then disable volume, but Asks for mount.
100 - Can be posible modify package to create and use configuration files in
105 /etc/bacula/bacula-dir.conf
106 /etc/bacula/conf.d/pools.conf
107 /etc/bacula/conf.d/clients.conf
108 /etc/bacula/conf.d/storages.conf
110 and into bacula-dir.conf file include
112 @/etc/bacula/conf.d/pools.conf
113 @/etc/bacula/conf.d/clients.conf
114 @/etc/bacula/conf.d/storages.conf
115 - Possibly add an Inconsistent state when a Volume is in error
117 - Fix #ifdefing so that smartalloc can be disabled. Check manual
118 -- the default is enabled.
119 - Change calling sequence to delete_job_id_range() in ua_cmds.c
120 the preceding strtok() is done inside the subroutine only once.
121 - Dangling softlinks are not restored properly. For example, take a
122 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
123 move the directory to another machine where the file /usr/share/autoconf does
124 not exist, back it up, then try a full restore. It fails.
125 - Softlinks that point to non-existent file are not restored in restore all,
126 but are restored if the file is individually selected. BUG!
127 - New directive "Delete purged Volumes"
129 - Prune by Job Level (Full, Differential, Incremental)
130 - Strict automatic pruning
131 - Implement unmount of USB volumes.
132 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
133 Win32 to avoid patent problems.
134 - Implement multiple jobid specification for the cancel command,
135 similar to what is permitted on the update slots command.
136 - modify pruning to keep a fixed number of versions of a file,
138 - the cd-command should allow complete paths
139 i.e. cd /foo/bar/foo/bar
140 -> if a customer mails me the path to a certain file,
141 its faster to enter the specified directory
142 - Make tree walk routines like cd, ls, ... more user friendly
143 by handling spaces better.
147 MA = (last_MA * 3 + rate) / 4
148 rate = (bytes - last_bytes) / (runtime - last_runtime)
149 - Add a recursive mark command (rmark) to restore.
150 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
151 of the same level and does not permit multiple simultaneous
152 running of that Job (i.e. lets any previous invocation finish
153 before doing Interval testing).
154 - Look at simplifying File exclusions.
156 - Auto update of slot:
157 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
158 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

161 02-Nov 12:58 rufus-sd JobId 10: 3301 Issuing autochanger "loaded? drive 0" command.
162 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
163 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
164 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.

166 - Separate Files and Directories in catalog
167 - Create FileVersions table
168 - Look at rsysnc for incremental updates and dedupping
169 - Add MD5 or SHA1 check in SD for data validation
170 - finish implementation of fdcalled -- see ua_run.c:105
171 - Fix problem in postgresql.c in my_postgresql_query, where the
172 generation of the error message doesn't differentiate result==NULL
173 and a bad status from that result. Not only that, the result is
174 cleared on a bail_out without having generated the error message.
176 - Implement SDErrors (must return from SD)
177 - Implement USB keyboard support in rescue CD.
178 - Implement continue spooling while despooling.
179 - Remove all install temp files in Win32 PLUGINSDIR.
180 - Audit retention periods to make sure everything is 64 bit.
181 - No where in restore causes kaboom.
182 - Performance: multiple spool files for a single job.
183 - Performance: despool attributes when despooling data (problem
184 multiplexing Dir connection).
185 - Make restore use the in-use volume reservation algorithm.
186 - When Pool specifies Storage command override does not work.
187 - Implement wait_for_sysop() message display in wait_for_device(), which
188 now prints warnings too often.
189 - Ensure that each device in an Autochanger has a different
191 - Look at sg_logs -a /dev/sg0 for getting soft errors.
192 - btape "test" command with Offline on Unmount = yes
194 This test is essential to Bacula.
196 I'm going to write one record in file 0,
197 two records in file 1,
198 and three records in file 2
200 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715
201 dev.c:714 Bad call to rewind. Device "LTO" (/dev/nst0) not open
202 02-Feb 11:00 btape: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation
203 Kaboom! btape, btape got signal 11. Attempting traceback.
205 - Encryption -- email from Landon
206 > The backup encryption algorithm is currently not configurable, and is
207 > set to AES_128_CBC in src/filed/backup.c. The encryption code
208 > supports a number of different ciphers (as well as adding arbitrary
209 > new ones) -- only a small bit of code would be required to map a
210 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is
211 > interested in implementing this functionality.
213 - Figure out some way to "automatically" backup conf changes.
214 - Add the OS version back to the Win32 client info.
215 - Restarted jobs have a NULL in the from field.
216 - Modify SD status command to indicate when the SD is writing
217 to a DVD (the device is not open -- see bug #732).
218 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
219 and possibly changing the blobs into varchar.
220 - Ensure that the SD re-reads the Media record if the JobFiles
221 does not match -- it may have been updated by another job.
223 - Test Volume compatibility between machine architectures
224 - Encryption documentation
225 - Wrong jobbytes with query 12 (todo)
226 - Bare-metal recovery Windows (todo)
231 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
233 - Maximum number of scratch volumes
235 - Next Pool (already have)
236 - Reclamation threshold
238 - Reuse delay (after all files purged from volume before it can be used)
239 - Copy Pool = xx, yyy (or multiple lines).
241 - Allow pool selection during restore.
243 - Average tape size from Eric
244 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
245 count(Media.MediaId) AS volnum,
246 sum(Media.VolBytes) AS voltotal,
247 Media.PoolId AS PoolId,
248 Media.MediaType AS MediaType
250 LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,
251 Media.MediaType AS MediaType
253 WHERE Media.VolStatus = 'Full'
254 GROUP BY Media.MediaType
255 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
256 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
260 - Add doc for bweb -- especially Installation
262 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
264 - Despool attributes in separate thread
267 - Check why restore repeatedly sends Rechdrs between
268 each data chunk -- according to James Harper 9Jan07.
271 - More intelligent re-run
273 - Incremental backup -- rsync, Stow
276 - Try to fix bscan not working with multiple DVD volumes bug #912.
277 - Look at mondo/mindi
278 - Make Bacula by default not backup tmpfs, procfs, sysfs, ...
279 - Fix hardlinked immutable files when linking a second file, the
280 immutable flag must be removed prior to trying to link it.
281 - Change dbcheck to tell users to use native tools for fixing
282 broken databases, and to ensure they have the proper indexes.
283 - add udev rules for Bacula devices.
284 - If a job terminates, the DIR connection can close before the
285 Volume info is updated, leaving the File count wrong.
286 - Look at why SIGPIPE during connection can cause seg fault in
287 writing the daemon message, when Dir dropped to bacula:bacula
288 - Look at zlib 32 => 64 problems.
289 - Possibly turn on St. Bernard code.
290 - Fix bextract to restore ACLs, or better yet, use common routines.
291 - Do we migrate appendable Volumes?
292 - Remove queue.c code.
293 - Print warning message if LANG environment variable does not specify
295 - New dot commands from Arno.
296 .show device=xxx lists information from one storage device, including
297 devices (I'm not even sure that information exists in the DIR...)
298 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
299 better machine-readable output like "Ok" or "Error busy"
300 .move eject device=xxx toslot=yyy the same as above, but with a new
301 target slot. The catalog should be updated accordingly.
302 .move transfer device=xxx fromslot=yyy toslot=zzz

482 If this is not a blank tape, try unmounting and remounting the Volume.
484 - http://www.dwheeler.com/essays/commercial-floss.html
485 - Add VolumeLock to prevent all but lock holder (SD) from updating
486 the Volume data (with the exception of VolumeState).
487 - The btape fill command does not seem to use the Autochanger
488 - Make Windows installer default to system disk drive.
489 - Look at using ioctl(FIOBMAP, ...) on Linux, and
490 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
491 Win32 for sparse files.
492 http://www.flexhex.com/docs/articles/sparse-files.phtml

494 - Directive: at <event> "command"
495 - Command: pycmd "command" generates "command" event. How to
496 attach to a specific job?
497 - Integrate Christopher's St. Bernard code.
498 - run_cmd() returns int should return JobId_t
499 - get_next_jobid_from_list() returns int should return JobId_t
500 - Document export LDFLAGS=-L/usr/lib64
501 - Don't attempt to restore from "Disabled" Volumes.
502 - Network error on Win32 should set Win32 error code.
503 - What happens when you rename a Disk Volume?
504 - Job retention period in a Pool (and hence Volume). The job would
506 - Look at -D_FORTIFY_SOURCE=2
507 - Add Win32 FileSet definition somewhere
508 - Look at fixing restore status stats in SD.
509 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
510 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
511 - Implement a mode that says when a hard read error is
512 encountered, read many times (as it currently does), and if the
513 block cannot be read, skip to the next block, and try again. If
514 that fails, skip to the next file and try again, ...
516 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
517 insert into LevelType (LevelType,LevelTypeLong) values
521 - Show files/second in client status output.
522 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
523 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
524 see if it become stable and I just have to supervise
526 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
527 PoolId, and when it is empty remove it.
529 - Allow Check Labels to be used with Bacula labels.
530 - "Resuming" a failed backup (lost line for example) by using the
531 failed backup as a sort of "base" job.
533 - Email to the user when the tape is about to need changing x
534 days before it needs changing.
535 - Command to show next tape that will be used for a job even
536 if the job is not scheduled.
537 - From: Arunav Mandal <amandal@trolltech.com>
538 1. When jobs are running and bacula for some reason crashes or if I do a
539 restart it remembers and jobs it was running before it crashed or restarted
540 as of now I loose all jobs if I restart it.
542 2. When spooling and in the midway if client is disconnected for instance a
543 laptop bacula completely discard the spool. It will be nice if it can write
544 that spool to tape so there will be some backups for that client if not all.
546 3. We have around 150 clients machines it will be nice to have a option to
547 upgrade all the client machines bacula version automatically.
549 4. Atleast one connection should be reserved for the bconsole so at heavy load
550 I should connect to the director via bconsole which at sometimes I can't
552 5. Another most important feature that is missing, say at 10am I manually
553 started backup of client abc and it was a full backup since client abc has
554 no backup history and at 10.30am bacula again automatically started backup of
555 client abc as that was in the schedule. So now we have 2 multiple Full
556 backups of the same client and if we again try to start a full backup of
557 client backup abc bacula won't complain. That should be fixed.
559 - For Windows disaster recovery see http://unattended.sf.net/
560 - regardless of the retention period, Bacula will not prune the
561 last Full, Diff, or Inc File data until a month after the
562 retention period for the last Full backup that was done.
563 - update volume=xxx --- add status=Full
564 - Remove old spool files on startup.
565 - Exclude SD spool/working directory.
566 - Refuse to prune last valid Full backup. Same goes for Catalog.
568 - Make a callback when Rerun failed levels is called.
569 - Give Python program access to Scheduled jobs.
570 - Add setting Volume State via Python.
571 - Python script to save with Python, not save, save with Bacula.
572 - Python script to do backup.
574 - Change the Priority, Client, Storage, JobStatus (error)
575 at the start of a job.
576 - Why is SpoolDirectory = /home/bacula/spool; not reported
577 as an error when writing a DVD?
578 - Make bootstrap file handle multiple MediaTypes (SD)
579 - Remove all old Device resource code in Dir and code to pass it
580 back in SD -- better, rework it to pass back device statistics.
581 - Check locking of resources -- be sure to lock devices where previously
582 resources were locked.
583 - The last part is left in the spool dir.
586 - In restore don't compare byte count on a raw device -- directory
587 entry does not contain bytes.
590 - Max Vols limit in Pool off by one?
591 - Implement Files/Bytes,... stats for restore job.
592 - Implement Total Bytes Written, ... for restore job.
593 - Despool attributes simultaneously with data in a separate
594 thread, rejoined at end of data spooling.
595 - 7. Implement new Console commands to allow offlining/reserving drives,
596 and possibly manipulating the autochanger (much asked for).
597 - Add start/end date editing in messages (%t %T, %e?) ...
598 - Add ClientDefs similar to JobDefs.
599 - Print more info when bextract -p accepts a bad block.
600 - Fix FD JobType to be set before RunBeforeJob in FD.
601 - Look at adding full Volume and Pool information to a Volume
602 label so that bscan can get *all* the info.
603 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
604 and there is only one volume in the pool, refuse to do it -- otherwise
605 he fills the Volume, then immediately starts reusing it.
606 - Implement copies and stripes.
607 - Add history file to console.
608 - Each file on tape creates a JobMedia record. Peter has 4 million
609 files spread over 10000 tape files and four tapes. A restore takes
610 16 hours to build the restore list.
611 - Add and option to check if the file size changed during backup.
612 - Make sure SD deletes spool files on error exit.
613 - Delete old spool files when SD starts.
614 - When labeling tapes, if you enter 000026, Bacula uses
615 the tape index rather than the Volume name 000026.
616 - Add offline tape command to Bacula console.
618 Enter MediaId or Volume name: 32
619 Enter new Volume name: DLT-20Dec04
620 Automatically selected Pool: Default

628 Label command failed for Volume DLT-20Dec04.
629 Do not forget to mount the drive!!!
630 - Bug: if a job is manually scheduled to run later, it does not appear
631 in any status report and cannot be cancelled.
636 How about introducing a Type = MgmtPolicy job type? That job type would
637 be responsible for scanning the Bacula environment looking for specific
638 conditions, and submitting the appropriate jobs for implementing said
642 Name = "Migration-Policy"
644 Policy Selection Job Type = Migrate
645 Scope = "<keyword> <operator> <regexp>"
646 Threshold = "<keyword> <operator> <regexp>"
647 Job Template = <template-name>
650 Where <keyword> is any legal job keyword, <operator> is a comparison
651 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
652 appropriate regexp. I could see an argument for Scope and Threshold
653 being SQL queries if we want to support full flexibility. The
654 Migration-Policy job would then get scheduled as frequently as a site
655 felt necessary (suggested default: every 15 minutes).
660 Name = "Migration-Policy"
662 Policy Selection Job Type = Migration
664 Threshold = "Migration Selection Type = LowestUtil"
665 Job Template = "MigrationTemplate"
668 would select all pools for examination and generate a job based on
669 MigrationTemplate to automatically select the volume with the lowest
670 usage and migrate it's contents to the nextpool defined for that pool.
672 This policy abstraction would be really handy for adjusting the behavior
673 of Bacula according to site-selectable criteria (one thing that pops
674 into mind is Amanda's ability to automatically adjust backup levels
675 depending on various criteria).
681 - Add Pool/Storage override regression test.
682 - Add delete JobId to regression.
683 - Add a regression test for dbcheck.
684 - New test to add bscan to four-concurrent-jobs regression,
685 i.e. after the four-concurrent jobs zap the
686 database as is done in the bscan-test, then use bscan to
687 restore the database, do a restore and compare with the
689 - Add restore of specific JobId to regression (item 3
690 on the restore prompt)
691 - Add IPv6 to regression
692 - Add database test to regression. Test each function like delete,
695 - AntiVir can slow down backups on Win32 systems.
696 - Win32 systems with FAT32 can be much slower than NTFS for
697 more than 1000 files per directory.
701 - A HOLD command to stop all jobs from starting.
702 - A PAUSE command to pause all running jobs ==> release the
704 - Media Type = LTO,LTO-2,LTO-3
705 Media Type Read = LTO,LTO2,LTO3
706 Media Type Write = LTO2, LTO3
708 === From Carsten Menke <bootsy52@gmx.net>
710 Following is a list of what I think in the situations where I'm faced with,
711 could be a usefull enhancement to bacula, which I'm certain other users will
712 benefit from as well.
714 1. NextJob/NextJobs Directive within a Job Resource in the form of
715 NextJobs = job1,job2.
718 I currently solved the problem with running multiple jobs each after each
719 by setting the Max Wait Time for a job to 8 hours, and give
720 the jobs different Priorities. However, there scenarios where
721 1 Job is directly depending on another job, so if the former job fails,
722 the job after it needn't to be run
723 while maybe other jobs should run despite of that
726 A Backup Job and a Verify job, if the backup job fails there is no need to run
727 the verify job, as the backup job already failed. However, one may like
728 to backup the Catalog to disk despite of that the main backup job failed.
731 I see that this is related to the Event Handlers which are on the ToDo
732 list, also it is maybe a good idea to check for the return value and
733 execute different actions based on the return value
736 3. offline capability to bconsole
739 Currently I use a script which I execute within the last Job via the
740 RunAfterJob Directive, to release and eject the tape.
741 So I have to call bconsole "release=Storage-Name" and afterwards
742 mt -f /dev/nst0 eject to get the tape out.
744 If I have multiple Storage Devices, than these may not be /dev/nst0 and
745 I have to modify the script or call it with parameters etc.
746 This would actually not be needed, as everything is already defined
747 in bacula-sd.conf and if I can invoke bconsole with the
748 storage name via $1 in the script than I'm done and information is
751 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
755 For the reason mentioned in 3. to have the ability to call a
756 script with /scripts/foobar %s and in the script use $1
757 to pass the Storage Name to bconsole
759 5. Setting Volume State within a Job Resource
762 Instead of using "Maximum Volume Jobs" in the Pool Resource,
763 I would have the possibilty to define
764 in a Job Resource that after this certain job is run, the Volume State
765 should be set to "Volume State = Used", this give more flexibility (IMHO).
767 6. Localization of Bacula Messages
770 Unfortunatley many,many people I work with don't speak english very well.
771 So if at least the Reporting messages would be localized then they
772 would understand that they have to change the tape,etc. etc.
774 I volunteer to do the german translations, and if I can convince my wife also
775 french and Morre (western african language).
777 7. OK, this is evil, probably bound to security risks and maybe not possible
778 due to the design of bacula.
780 Implementation of Backtics ( `command` ) for shell comand execution to
781 the "Label Format" Directive.
785 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
786 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
787 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
788 the localized name for the day of the week appended to the
789 format string. Then I have the tape labeled automatically with weekday
790 name in the correct language.
792 - Make output from status use html table tags for nicely
793 presenting in a browser.
794 - Browse generations of files.
795 - I've seen an error when my catalog's File table fills up. I
796 then have to recreate the File table with a larger maximum row
797 size. Relevant information is at
798 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
799 "Installing and Configuring MySQL" chapter should talk a bit
800 about this potential problem, and recommend a solution.
801 - For Solaris must use POSIX awk.
802 - Want speed of writing to tape while despooling.
803 - Supported autochanger:
811 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
812 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
813 - Add regex from http://www.pcre.org to Bacula for Win32.
814 - Use only shell tools no make in CDROM package.
815 - Include within include does it work?
816 - Implement a Pool of type Cleaning?
817 - Implement VolReadTime and VolWriteTime in SD
818 - Modify Backing up Your Database to include a bootstrap file.
819 - Think about making certain database errors fatal.
820 - Look at correcting the time jump in the scheduler for daylight
821 savings time changes.
822 - Add a "real" timer to network connections.
823 - Promote to Full = Time period
824 - Check dates entered by user for correctness (month/day/... ranges)
825 - Compress restore Volume listing by date and first file.
826 - Look at patches/bacula_db.b2z postgresql that loops during restore.
828 - Perhaps add read/write programs and/or plugins to FileSets.
829 - How to handle backing up portables ...
830 - Add some sort of guaranteed Interval for upgrading jobs.
831 - Can we write the state file after every job terminates? On Win32
832 the system crashes and the state file is not updated.
835 Documentation to do: (any release a little bit at a time)
836 - Doc to do unmount before removing magazine.
837 - Alternative to static linking "ldd prog" save all binaries listed,
838 restore them and point LD_LIBRARY_PATH to them.
839 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
840 - Document query file format.
841 - Add more documentation for bsr files.
842 - Document problems with Verify and pruning.
843 - Document how to use multiple databases.
844 - VXA drives have a "cleaning required"
845 indicator, but Exabyte recommends preventive cleaning after every 75
848 In this context, it should be noted that Exabyte has a command-line
849 vxatool utility available for free download. (The current version is
850 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
851 test the drive, unload tapes, change drive settings, flash new firmware,
853 Of particular interest in this context is that vxatool <device> -i will
854 report, among other details, the time since last cleaning in tape motion
855 minutes. This information can be retrieved (and settings changed, for
856 that matter) through the generic-SCSI device even when Bacula has the
857 regular tape device locked. (Needless to say, I don't recommend
858 changing tape settings while a job is running.)
859 - Lookup HP cleaning recommendations.
860 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
861 - Document doing table repair
864 ===================================
865 - Add macro expansions in JobDefs.
866 Run Before Job = "SomeFile %{Level} %{Client}"
867 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
868 - Use non-blocking network I/O but if no data is available, use
870 - Use gather write() for network I/O.
871 - Autorestart on crash.
872 - Add bandwidth limiting.
873 - When an error in input occurs and conio beeps, you can back
874 up through the prompt.
875 - Detect fixed tape block mode during positioning by looking at
876 block numbers in btape "test". Possibly adjust in Bacula.
877 - Fix list volumes to output volume retention in some other
878 units, perhaps via a directive.
879 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
880 with multiple priorities.
881 - If you use restore replace=never, the directory attributes for
882 non-existent directories will not be restored properly.
884 - see lzma401.zip in others directory for new compression
886 - Allow the user to select JobType for manual pruning/purging.
887 - bscan does not put first of two volumes back with all info in
889 - Figure out how to make named console messages go only to that
890 console and to the non-restricted console (new console class?).
891 - Make restricted console prompt for password if *ask* is set or
892 perhaps if password is undefined.
893 - Implement "from ISO-date/time every x hours/days/weeks/months" in
896 ==== from Marc Schoechlin
897 - the help-command should be more verbose
898 (it should explain the paramters of the different
900 -> its time-comsuming to consult the manual anytime
901 you need a special parameter
902 -> maybe its more easy to maintain this, if the
903 descriptions of that commands are outsourced to
905 - if the password is not configured in bconsole.conf
906 you should be asked for it.
907 -> sometimes you like to do restore on a customer-machine
908 which shouldnt know the password for bacula.
909 -> adding the password to the file favours admins
910 to forget to remove the password after usage
912 the protection of that file is less important
913 - long-listed-output of commands should be scrollable
914 like the unix more/less-command does
915 -> if someone runs 200 and more machines, the lists could
916 be a little long and complex
917 - command-output should be shown column by column
918 to reduce scrolling and to increase clarity
920 - lsmark should list the selected files with full
922 - wildcards for selecting and file and directories would be nice
923 - any actions should be interuptable with STRG+C
924 - command-expansion would be pretty cool
926 - When the replace Never option is set, new directory permissions
927 are not restored. See bug 213. To fix this requires creating a
928 list of newly restored directories so that those directory
929 permissions *can* be restored.
930 - Add prune all command
931 - Document fact that purge can destroy a part of a restore by purging
932 one volume while others remain valid -- perhaps mark Jobs.
933 - Add multiple-media-types.txt
934 - look at mxt-changer.html
935 - Make ? do a help command (no return needed).
936 - Implement restore directory.
937 - Document streams and how to implement them.
938 - Try not to re-backup a file if a new hard link is added.
939 - Add feature to backup hard links only, but not the data.
940 - Fix stream handling to be simpler.
941 - Add Priority and Bootstrap to Run a Job.
942 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
944 - Remove View FileSet button from Run a Job dialog.
945 - Handle prompt for restore job at end of Restore command.
946 - Add display of total selected files to Restore window.
947 - Add tree pane to left of window.
948 - Add progress meter.
949 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
950 - Add message to user to check for fixed block size when the forward
951 space test fails in btape.
952 - When unmarking a directory check if all files below are unmarked and
953 then remove the + flag -- in the restore tree.
954 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
955 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
956 - Revisit the question of multiple Volumes (disk) on a single device.
957 - Add a block copy option to bcopy.
958 - Fix "llist jobid=xx" where no fileset or client exists.
959 - For each job type (Admin, Restore, ...) require only the really necessary
960 fields.- Pass Director resource name as an option to the Console.
961 - Add a "batch" mode to the Console (no unsolicited queries, ...).
962 - Allow browsing the catalog to see all versions of a file (with
963 stat data on each file).
964 - Restore attributes of directory if replace=never set but directory
966 - Use SHA1 on authentication if possible.
967 - See comtest-xxx.zip for Windows code to talk to USB.
968 - Add John's appended files:
969 Appended = { /files/server/logs/http/*log }
970 and such files would be treated as follows.On a FULL backup, they would
971 be backed up like any other file.On an INCREMENTAL backup, where a
972 previous INCREMENTAL or FULL was already in thecatalogue and the length
973 of the file wasgreater than the length of the last backup, only thedata
974 added since the last backup will be dumped.On an INCREMENTAL backup, if
975 the length of the file is less than thelength of the file with the same
976 name last backed up, the completefile is dumped.On Windows systems, with
977 creation date of files, we can be evensmarter about this and not count
978 entirely upon the length.On a restore, the full and all incrementals
979 since it will beapplied in sequence to restore the file.
980 - Check new HAVE_WIN32 open bits.
981 - Check if the tape has moved before writing.
982 - Handling removable disks -- see below:
983 - Add FromClient and ToClient keywords on restore command (or
984 BackupClient RestoreClient).
985 - Implement a JobSet, which groups any number of jobs. If the
986 JobSet is started, all the jobs are started together.
987 Allow Pool, Level, and Schedule overrides.
988 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
989 correctly for multiple simultaneous jobs.
990 - Implement the Media record flag that indicates that the Volume does disk
992 - Implement VolAddr, which is used when Volume is addressed like a disk,
993 and form it from VolFile and VolBlock.
994 - Fix fast block rejection (stored/read_record.c:118). It passes a null
995 pointer (rec) to try_repositioning().
996 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
997 which would take precidence over the Catalog "JobRetention".
998 - Implement Label Format in Add and Label console commands.
999 - Put email tape request delays on one or more variables. User wants
1000 to cancel the job after a certain time interval. Maximum Mount Wait?
1001 - Job, Client, Device, Pool, or Volume?
1002 Is it possible to make this a directive which is *optional* in multiple
1003 resources, like Level? If so, I think I'd make it an optional directive
1004 in Job, Client, and Pool, with precedence such that Job overrides Client
1005 which in turn overrides Pool.
1007 - New Storage specifications:
1008 - Want to write to multiple storage devices simultaneously
1009 - Want to write to multiple storage devices sequentially (in one job)
1010 - Want to read/write simultaneously
1011 - Key is MediaType -- it must match
1013 Passed to SD as a sort of BSR record called Storage Specification
1017 MediaType -> Next MediaType
1019 Device -> Next Device
1021 Allow multiple Storage specifications
1029 Allow Multiple Pool specifications (note, Pool currently
1031 Allow Multiple MediaType specifications in Dir conf
1032 Allow Multiple Device specifications in Dir conf
1033 Perhaps keep this in a single SSR
1034 Tie a Volume to a specific device by using a MediaType that
1035 is contained in only one device.
1036 In SD allow Device to have Multiple MediaTypes
1038 - Ideas from Jerry Scharf:
1039 First let's point out some big pluses that bacula has for this
1041 more importantly it's active. Thank you so much for that
1042 even more important, it's not flaky
1043 it has an open access catalog, opening many possibilities
1044 it's pushing toward heterogeneous systems capability
1046 Macintosh file client
1047 macs are an interesting niche, but I fear a server is a rathole
1048 working bare iron recovery for windows
1049 the option for inc/diff backups not reset on fileset revision
1050 a) use both change and inode update time against base time
1051 b) do the full catalog check (expensive but accurate)
1052 sizing guide (how much system is needed to back up N systems/files)
1053 consultants on using bacula in building a disaster recovery system
1054 an integration guide
1055 or how to get at fancy things that one could do with bacula
1056 logwatch code for bacula logs (or similar)
1057 linux distro inclusion of bacula (brings good and bad, but necessary)
1058 win2k/XP server capability (icky but you asked)
1059 support for Oracle database ??
1061 - Look at adding SQL server and Exchange support for Windows.
1062 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1063 is needed to properly specify ranges.
1064 - Add progress of files/bytes to SD and FD.
1065 - Print warning message if FileId > 4 billion
1066 - do a "messages" before the first prompt in Console
1067 - Client does not show busy during Estimate command.
1068 - Implement Console mtx commands.
1069 - Implement a Mount Command and an Unmount Command where
1070 the users could specify a system command to be performed
1071 to do the mount, after which Bacula could attempt to
1072 read the device. This is for Removeable media such as a CDROM.
1073 - Most likely, this mount command would be invoked explicitly
1074 by the user using the current Console "mount" and "unmount"
1075 commands -- the Storage Daemon would do the right thing
1076 depending on the exact nature of the device.
1077 - As with tape drives, when Bacula wanted a new removable
1078 disk mounted, it would unmount the old one, and send a message
1079 to the user, who would then use "mount" as described above
1080 once he had actually inserted the disk.
1081 - Implement dump/print label to UA
1082 - Spool to disk only when the tape is full, then when a tape is hung move
1084 - bextract is sending everything to the log file ****FIXME****
1085 - Allow multiple Storage specifications (or multiple names on
1086 a single Storage specification) in the Job record. Thus a job
1087 can be backed up to a number of storage devices.
1088 - Implement some way for the File daemon to contact the Director
1089 to start a job or pass its DHCP obtained IP number.
1090 - Implement a query tape prompt/replace feature for a console
1091 - Make sure that Bacula rechecks the tape after the 20 min wait.
1092 - Set IO_NOWAIT on Bacula TCP/IP packets.
1093 - Try doing a raw partition backup and restore by mounting a
1095 - From Lars Kellers:
1096 Yes, it would allow to highly automatic the request for new tapes. If a
1097 tape is empty, bacula reads the barcodes (native or simulated), and if
1098 an unused tape is found, it runs the label command with all the
1099 necessary parameters.
1101 By the way can bacula automatically "move" an empty/purged volume say
1102 in the "short" pool to the "long" pool if this pool runs out of volume
1104 - What to do about "list files job=xxx".
1105 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1106 file descriptor leak in Bacula.
1107 - Can we dynamically change FileSets?
1108 - If pool specified to label command and Label Format is specified,
1109 automatically generate the Volume name.
1110 - Add ExhautiveRestoreSearch
1111 - Look at the possibility of loading only the necessary
1112 data into the restore tree (i.e. do it one directory at a
1113 time as the user walks through the tree).
1114 - Possibly use the hash code if the user selects all for a restore command.
1115 - Fix "restore all" to bypass building the tree.
1116 - Prohibit backing up archive device (findlib/find_one.c:128)
1117 - Implement Release Device in the Job resource to unmount a drive.
1118 - Implement Acquire Device in the Job resource to mount a drive,
1119 be sure this works with admin jobs so that the user can get
1120 prompted to insert the correct tape. Possibly some way to say to
1121 run the job but don't save the files.
1122 - Make things like list where a file is saved case independent for
1124 - Implement a Recycle command
1125 - Start working on Base jobs.
1126 - From Phil Stracchino:
1127 It would probably be a per-client option, and would be called
1128 something like, say, "Automatically purge obsoleted jobs". What it
1129 would do is, when you successfully complete a Differential backup of a
1130 client, it would automatically purge all Incremental backups for that
1131 client that are rendered redundant by that Differential. Likewise,
1132 when a Full backup on a client completed, it would automatically purge
1133 all Differential and Incremental jobs obsoleted by that Full backup.
1134 This would let people minimize the number of tapes they're keeping on
1135 hand without having to master the art of retention times.
1136 - When doing a Backup send all attributes back to the Director, who
1137 would then figure out what files have been deleted.
1138 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1139 explicit permission to do so. It should also mark the tape in error
1140 if there is an error.
1141 - Cancel waiting for Client connect in SD if FD goes away.
1143 - Implement timeout in response() when it should come quickly.
1144 - Implement a Slot priority (loaded/not loaded).
1145 - Implement "vacation" Incremental only saves.
1146 - Implement create "FileSet"?
1147 - Add prefixlinks to where or not where absolute links to FD.
1148 - Issue message to mount a new tape before the rewind.
1149 - Simplified client job initiation for portables.
1150 - If SD cannot open a drive, make it periodically retry.
1151 - Add more of the config info to the tape label.
1153 - Refine SD waiting output:
1154 Device is being positioned
1155 > Device is being positioned for append
1156 > Device is being positioned to file x
1158 - Figure out some way to estimate output size and to avoid splitting
1159 a backup across two Volumes -- this could be useful for writing CDROMs
1160 where you really prefer not to have it split -- not serious.
1161 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1162 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1163 actual data on the Volume and compare it.
1164 - Make bcopy read through bad tape records.
1165 - Program files (i.e. execute a program to read/write files).
1166 Pass read date of last backup, size of file last time.
1167 - Add Signature type to File DB record.
1168 - CD into subdirectory when open()ing files for backup to
1169 speed up things. Test with testfind().
1170 - Priority job to go to top of list.
1171 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1172 - Implement some way for the Console to dynamically create a job.
1173 - Solaris -I on tar for include list
1174 - Need a verbose mode in restore, perhaps to bsr.
1175 - bscan without -v is too quiet -- perhaps show jobs.
1176 - Add code to reject whole blocks if not wanted on restore.
1177 - Check if we can increase Bacula FD priorty in Win2000
1178 - Check if both CatalogFiles and UseCatalog are set to SD.
1179 - Possibly add email to Watchdog if drive is unmounted too
1180 long and a job is waiting on the drive.
1181 - After unmount, if restore job started, ask to mount.
1182 - Add UA rc and history files.
1183 - put termcap (used by console) in ./configure and
1184 allow -with-termcap-dir.
1185 - Fix Autoprune for Volumes to respect need for full save.
1186 - Compare tape to Client files (attributes, or attributes and data)
1187 - Make all database Ids 64 bit.
1188 - Allow console commands to detach or run in background.
1189 - Add SD message variables to control operator wait time
1190 - Maximum Operator Wait
1191 - Minimum Message Interval
1192 - Maximum Message Interval
1193 - Send Operator message when cannot read tape label.
1194 - Verify level=Volume (scan only), level=Data (compare of data to file).
1195 Verify level=Catalog, level=InitCatalog
1197 - Add keyword search to show command in Console.
1198 - Events : tape has more than xxx bytes.
1199 - Complete code in Bacula Resources -- this will permit
1200 reading a new config file at any time.
1201 - Handle ctl-c in Console
1202 - Implement script driven addition of File daemon to config files.
1203 - Think about how to make Bacula work better with File (non-tape) archives.
1204 - Write Unix emulator for Windows.
1205 - Make database type selectable by .conf files i.e. at runtime
1206 - Set flag for uname -a. Add to Volume label.
1207 - Restore files modified after date
1208 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1209 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1210 - Timout a job or terminate if link goes down, or reopen link and query.
1211 - Concept of precious tapes (cannot be reused).
1212 - Make bcopy copy with a single tape drive.
1213 - Permit changing ownership during restore.

1227 - Autolabel should be specified by DIR instead of SD.
1229 - Add media capacity
1230 - AutoScan (check checksum of tape)
1231 - Format command = "format /dev/nst0"
1235 - Seek resolution (usually corresponds to buffer size)
1236 - EODErrorCode=ENOSPC or code
1237 - Partial Read error code
1238 - Partial write error code
1239 - Nonformatted read error
1240 - Nonformatted write error
1241 - WriteProtected error
1245 - IgnoreCloseErrors=yes
1255 - Write a Storage daemon that uses pipes and
1256 standard Unix programs to write to the tape.
1258 - Need something that monitors the JCR queue and
1259 times out jobs by asking the deamons where they are.
1260 - Enhance Jmsg code to permit buffering and saving to disk.
1261 - Verify from Volume
1262 - Need report class for messages. Perhaps
1263 report resource where report=group of messages
1264 - enhance scan_attrib and rename scan_jobtype, and
1265 fill in code for "since" option
1266 - Director needs a time after which the report status is sent
1267 anyway -- or better yet, a retry time for the job.
1268 - Don't reschedule a job if previous incarnation is still running.
1269 - Some way to automatically backup everything is needed????
1270 - Need a structure for pending actions:
1272 - termination status (part of buffered msgs?)
1274 Read, Write, Clean, Delete
1275 - Login to Bacula; Bacula users with different permissions:
1276 owner, group, user, quotas
1277 - Store info on each file system type (probably in the job header on tape.
1278 This could be the output of df; or perhaps some sort of /etc/mtab record.
1280 ========= ideas ===============
1281 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1282 To: <kern@sibbald.com>
1283 Subject: RE: [Bacula-users] future large programming jobs
1284 Date: Thu, 26 Feb 2004 11:34:54 -0600
1286 I noticed the subject thread and thought I would offer the following
1287 merely as sources of ideas, i.e. something to think about, not even as
1288 strong as a request. In my former life (before retiring) I often
1289 dealt with backups and storage management issues/products as a
1290 developer and as a consultant. I am currently migrating my personal
1291 network from amanda to bacula specifically because of the ability to
1292 cross media boundaries during storing backups.
1293 Are you familiar with the commercial product called ADSM (I think IBM
1294 now sells it under the Tivoli label)? It has a couple of interesting
1295 ideas that may apply to the following topics.
1297 1. Migration: Consider that when you need to restore a system, there
1298 may be pressure to hurry. If all the information for a single client
1299 can eventually end up on the same media (and in chronological order),
1300 the restore is facillitated by not having to search past information
1301 from other clients. ADSM has the concept of "client affinity" that
1302 may be associated with it's storage pools. It seems to me that this
1303 concept (as an optional feature) might fit in your architecture for
1306 ADSM also has the concept of defining one or more storage pools as
1307 "copy pools" (almost mirrors, but only in the sense of contents).
1308 These pools provide the ability to have duplicte data stored both
1309 onsite and offsite. The copy process can be scheduled to be handled
1310 by their storage manager during periods when there is no backup
1311 activity. Again, the migration process might be a place to consider
1312 implementing something like this.
1315 > It strikes me that it would be very nice to be able to do things
1317 > have the Job(s) backing up the machines run, and once they have all

1323 > mechanism described below would probably make it very easy.
1325 This is the goal. In the first step (before events), you simply
1327 the Migration to tape later.
1329 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1330 the database. Once a file (unique by path and metadata such as dates,
1331 size, ownership, etc.) is in a copy pool, no more copies are made. In
1332 other words, when you start ADSM, it begins like your concept of a
1333 base job. After that it is in the "incremental" mode. You can
1334 configure the number of "generations" of files to be retained, plus a
1335 retention date after which even old generations are purged. The
1336 database tracks the contents of media and projects the percentage of
1337 each volume that is valid. When the valid content of a volume drops
1338 below a configured percentage, the valid data are migrated to another
1339 volume and the old volume is marked as empty. Note, this requires
1340 ADSM to have an idea of the contents of a client, i.e. marking the
1341 database when an existing file was deleted, but this would solve your
1342 issue of restoring a client without restoring deleted files.
1344 This is pretty far from what bacula now does, but if you are going to
1345 rip things up for Base jobs,.....
1346 Also, the benefits of this are huge for very large shops, especially
1347 with media robots, but are a pain for shops with manual media
1351 > Base jobs sound pretty useful, but I'm not dying for them.
1353 Nobody is dying for them, but when you see what it does, you will die
1359 ==============================
1362 - Implement FSM (File System Modules).
1363 - Audit M_ error codes to ensure they are correct and consistent.
1364 - Add variable break characters to lex analyzer.
1365 Either a bit mask or a string of chars so that
1366 the caller can change the break characters.
1367 - Make a single T_BREAK to replace T_COMMA, etc.
1368 - Ensure that File daemon and Storage daemon can
1369 continue a save if the Director goes down (this
1370 is NOT currently the case). Must detect socket error,
1371 buffer messages for later.
1372 - Add ability to backup to two Storage devices (two SD sessions) at
1373 the same time -- e.g. onsite, offsite.
1375 ======================================================
1377 It is somewhat like a Full save becomes an incremental since
1378 the Base job (or jobs) plus other non-base files.
1380 - A Base backup is same as Full backup, just different type.
1381 - New BaseFiles table that contains:
1383 BaseJobId - Base JobId referenced for this FileId (needed ???)
1384 JobId - JobId currently running
1385 FileId - File not backed up, exists in Base Job
1386 FileIndex - FileIndex from Base Job.
1387 i.e. for each base file that exists but is not saved because
1388 it has not changed, the File daemon sends the JobId, BaseId,
1389 FileId, FileIndex back to the Director who creates the DB entry.
1390 - To initiate a Base save, the Director sends the FD
1391 the FileId, and full filename for each file in the Base.
1392 - When the FD finds a Base file, he requests the Director to
1393 send him the full File entry (stat packet plus MD5), or
1394 conversely, the FD sends it to the Director and the Director
1395 says yes or no. This can be quite rapid if the FileId is kept
1396 by the FD for each Base Filename.
1397 - It is probably better to have the comparison done by the FD
1398 despite the fact that the File entry must be sent across the
1400 - An alternative would be to send the FD the whole File entry
1401 from the start. The disadvantage is that it requires a lot of
1402 space. The advantage is that it requires less communications
1404 - The Job record must be updated to indicate that one or more
1406 - At end of Job, FD returns:
1407 1. Count of base files/bytes not written to tape (i.e. matches)
1408 2. Count of base file that were saved i.e. had changed.
1409 - No tape record would be written for a Base file that matches, in the
1410 same way that no tape record is written for Incremental jobs where
1411 the file is not saved because it is unchanged.
1412 - On a restore, all the Base file records must explicitly be
1413 found from the BaseFile tape. I.e. for each Full save that is marked
1414 to have one or more Base Jobs, search the BaseFile for all occurrences
1416 - An optimization might be to make the BaseFile have:
1422 This would avoid the need to explicitly fetch each File record for
1423 the Base job. The Base Job record will be fetched to get the
1424 VolSessionId and VolSessionTime.

1428 Handling removable disks
1430 From: Karl Cunningham <karlc@keckec.com>
1432 My backups are only to hard disk these days, in removable bays. This is my
1433 idea of how a backup to hard disk would work more smoothly. Some of these
1434 things Bacula does already, but I mention them for completeness. If others
1435 have better ways to do this, I'd like to hear about it.
1437 1. Accommodate several disks, rotated similar to how tapes are. Identified
1438 by partition volume ID or perhaps by the name of a subdirectory.
1439 2. Abort & notify the admin if the wrong disk is in the bay.
1440 3. Write backups to different subdirectories for each machine to be backed
1442 4. Volumes (files) get created as needed in the proper subdirectory, one
1444 5. When a disk is recycled, remove or zero all old backup files. This is
1445 important as the disk being recycled may be close to full. This may be
1446 better done manually since the backup files for many machines may be
1447 scattered in many subdirectories.
1454 - Fix bpipe.c so that it does not modify results pointer.
1455 ***FIXME*** calling sequence should be changed.
