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

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
76 - Why no error message if restore has no permission on the where
78 - Possibly allow manual "purge" to purge a Volume that has not
79 yet been written (even if FirstWritten time is zero) see ua_purge.c
81 - Add disk block detection bsr code (make it work).
83 - Add blast attributes to DIR to SD.
84 - Detect deadlocks in reservations.
86 - Add list during dump
87 - Add in plugin code flag
88 - Add bRC_EndJob -- stops more calls to plugin this job
89 - Add bRC_Term (unload plugin)
90 - remove time_t from Jmsg and use utime_t?
92 - Deadlock detection, watchdog sees if counter advances when jobs are
93 running. With debug on, can do a "status" command.
94 - User options for plugins.
95 - Pool Storage override precidence over command line.
96 - Autolabel only if Volume catalog information indicates tape not
97 written. This will avoid overwriting a tape that gets an I/O
98 error on reading the volume label.
99 - I/O error, SD thinks it is not the right Volume, should check slot
100 then disable volume, but Asks for mount.
101 - Can be posible modify package to create and use configuration files in
106 /etc/bacula/bacula-dir.conf
107 /etc/bacula/conf.d/pools.conf
108 /etc/bacula/conf.d/clients.conf
109 /etc/bacula/conf.d/storages.conf
111 and into bacula-dir.conf file include
113 @/etc/bacula/conf.d/pools.conf
114 @/etc/bacula/conf.d/clients.conf
115 @/etc/bacula/conf.d/storages.conf
116 - Possibly add an Inconsistent state when a Volume is in error
118 - Fix #ifdefing so that smartalloc can be disabled. Check manual
119 -- the default is enabled.
120 - Change calling sequence to delete_job_id_range() in ua_cmds.c
121 the preceding strtok() is done inside the subroutine only once.
122 - Dangling softlinks are not restored properly. For example, take a
123 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
124 move the directory to another machine where the file /usr/share/autoconf does
125 not exist, back it up, then try a full restore. It fails.
126 - Softlinks that point to non-existent file are not restored in restore all,
127 but are restored if the file is individually selected. BUG!
128 - New directive "Delete purged Volumes"
130 - Prune by Job Level (Full, Differential, Incremental)
131 - Strict automatic pruning
132 - Implement unmount of USB volumes.
133 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
134 Win32 to avoid patent problems.
135 - Implement multiple jobid specification for the cancel command,
136 similar to what is permitted on the update slots command.
137 - modify pruning to keep a fixed number of versions of a file,
139 - the cd-command should allow complete paths
140 i.e. cd /foo/bar/foo/bar
141 -> if a customer mails me the path to a certain file,
142 its faster to enter the specified directory
143 - Make tree walk routines like cd, ls, ... more user friendly
144 by handling spaces better.
145 - When doing a restore, if the user does an "update slots"
146 after the job started in order to add a restore volume, the
147 values prior to the update slots will be put into the catalog.
148 Must retrieve catalog record merge it then write it back at the
149 end of the restore job, if we want to do this right.
153 MA = (last_MA * 3 + rate) / 4
154 rate = (bytes - last_bytes) / (runtime - last_runtime)
155 - Add a recursive mark command (rmark) to restore.
156 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
157 of the same level and does not permit multiple simultaneous
158 running of that Job (i.e. lets any previous invocation finish
159 before doing Interval testing).
160 - Look at simplifying File exclusions.
162 - Auto update of slot:
163 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
164 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

167 02-Nov 12:58 rufus-sd JobId 10: 3301 Issuing autochanger "loaded? drive 0" command.
168 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
169 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
170 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.
171 02-Nov 12:58 rufus-dir JobId 10: Bacula rufus-dir 2.3.6 (26Oct07): 02-Nov-2007 12:58:51
172 - Separate Files and Directories in catalog
173 - Create FileVersions table
174 - Look at rsysnc for incremental updates and dedupping
175 - Add MD5 or SHA1 check in SD for data validation
176 - finish implementation of fdcalled -- see ua_run.c:105
177 - Fix problem in postgresql.c in my_postgresql_query, where the
178 generation of the error message doesn't differentiate result==NULL
179 and a bad status from that result. Not only that, the result is
180 cleared on a bail_out without having generated the error message.
182 - Implement SDErrors (must return from SD)
183 - Implement USB keyboard support in rescue CD.
184 - Implement continue spooling while despooling.
185 - Remove all install temp files in Win32 PLUGINSDIR.
186 - Audit retention periods to make sure everything is 64 bit.
187 - No where in restore causes kaboom.
188 - Performance: multiple spool files for a single job.
189 - Performance: despool attributes when despooling data (problem
190 multiplexing Dir connection).
191 - Make restore use the in-use volume reservation algorithm.
192 - When Pool specifies Storage command override does not work.
193 - Implement wait_for_sysop() message display in wait_for_device(), which
194 now prints warnings too often.
195 - Ensure that each device in an Autochanger has a different
197 - Look at sg_logs -a /dev/sg0 for getting soft errors.
198 - btape "test" command with Offline on Unmount = yes
200 This test is essential to Bacula.
202 I'm going to write one record in file 0,
203 two records in file 1,
204 and three records in file 2
206 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715

209 Kaboom! btape, btape got signal 11. Attempting traceback.
211 - Encryption -- email from Landon
212 > The backup encryption algorithm is currently not configurable, and is
213 > set to AES_128_CBC in src/filed/backup.c. The encryption code
214 > supports a number of different ciphers (as well as adding arbitrary
215 > new ones) -- only a small bit of code would be required to map a
216 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is
217 > interested in implementing this functionality.
219 - Figure out some way to "automatically" backup conf changes.
220 - Add the OS version back to the Win32 client info.
221 - Restarted jobs have a NULL in the from field.
222 - Modify SD status command to indicate when the SD is writing
223 to a DVD (the device is not open -- see bug #732).
224 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
225 and possibly changing the blobs into varchar.
226 - Ensure that the SD re-reads the Media record if the JobFiles
227 does not match -- it may have been updated by another job.
229 - Test Volume compatibility between machine architectures
230 - Encryption documentation
231 - Wrong jobbytes with query 12 (todo)
232 - Bare-metal recovery Windows (todo)
237 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
239 - Maximum number of scratch volumes
241 - Next Pool (already have)
242 - Reclamation threshold
244 - Reuse delay (after all files purged from volume before it can be used)
245 - Copy Pool = xx, yyy (or multiple lines).
247 - Allow pool selection during restore.
249 - Average tape size from Eric
250 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg

252 sum(Media.VolBytes) AS voltotal,
253 Media.PoolId AS PoolId,
254 Media.MediaType AS MediaType
256 LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,

260 GROUP BY Media.MediaType
261 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
262 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
266 - Add doc for bweb -- especially Installation
268 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
270 - Despool attributes in separate thread
273 - Check why restore repeatedly sends Rechdrs between
274 each data chunk -- according to James Harper 9Jan07.
277 - More intelligent re-run
279 - Incremental backup -- rsync, Stow
282 - Try to fix bscan not working with multiple DVD volumes bug #912.
283 - Look at mondo/mindi
284 - Make Bacula by default not backup tmpfs, procfs, sysfs, ...
285 - Fix hardlinked immutable files when linking a second file, the
286 immutable flag must be removed prior to trying to link it.
287 - Change dbcheck to tell users to use native tools for fixing
288 broken databases, and to ensure they have the proper indexes.
289 - add udev rules for Bacula devices.
290 - If a job terminates, the DIR connection can close before the
291 Volume info is updated, leaving the File count wrong.
292 - Look at why SIGPIPE during connection can cause seg fault in
293 writing the daemon message, when Dir dropped to bacula:bacula
294 - Look at zlib 32 => 64 problems.
295 - Possibly turn on St. Bernard code.
296 - Fix bextract to restore ACLs, or better yet, use common routines.
297 - Do we migrate appendable Volumes?
298 - Remove queue.c code.
299 - Print warning message if LANG environment variable does not specify
301 - New dot commands from Arno.
302 .show device=xxx lists information from one storage device, including
303 devices (I'm not even sure that information exists in the DIR...)
304 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
305 better machine-readable output like "Ok" or "Error busy"
306 .move eject device=xxx toslot=yyy the same as above, but with a new
307 target slot. The catalog should be updated accordingly.
308 .move transfer device=xxx fromslot=yyy toslot=zzz

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

500 - Directive: at <event> "command"
501 - Command: pycmd "command" generates "command" event. How to
502 attach to a specific job?
503 - Integrate Christopher's St. Bernard code.
504 - run_cmd() returns int should return JobId_t
505 - get_next_jobid_from_list() returns int should return JobId_t
506 - Document export LDFLAGS=-L/usr/lib64
507 - Don't attempt to restore from "Disabled" Volumes.
508 - Network error on Win32 should set Win32 error code.
509 - What happens when you rename a Disk Volume?
510 - Job retention period in a Pool (and hence Volume). The job would
512 - Look at -D_FORTIFY_SOURCE=2
513 - Add Win32 FileSet definition somewhere
514 - Look at fixing restore status stats in SD.
515 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
516 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
517 - Implement a mode that says when a hard read error is
518 encountered, read many times (as it currently does), and if the
519 block cannot be read, skip to the next block, and try again. If
520 that fails, skip to the next file and try again, ...
522 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
523 insert into LevelType (LevelType,LevelTypeLong) values
527 - Show files/second in client status output.
528 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
529 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
530 see if it become stable and I just have to supervise
532 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
533 PoolId, and when it is empty remove it.
535 - Allow Check Labels to be used with Bacula labels.
536 - "Resuming" a failed backup (lost line for example) by using the
537 failed backup as a sort of "base" job.
539 - Email to the user when the tape is about to need changing x
540 days before it needs changing.
541 - Command to show next tape that will be used for a job even
542 if the job is not scheduled.
543 - From: Arunav Mandal <amandal@trolltech.com>
544 1. When jobs are running and bacula for some reason crashes or if I do a
545 restart it remembers and jobs it was running before it crashed or restarted
546 as of now I loose all jobs if I restart it.
548 2. When spooling and in the midway if client is disconnected for instance a
549 laptop bacula completely discard the spool. It will be nice if it can write
550 that spool to tape so there will be some backups for that client if not all.
552 3. We have around 150 clients machines it will be nice to have a option to
553 upgrade all the client machines bacula version automatically.
555 4. Atleast one connection should be reserved for the bconsole so at heavy load
556 I should connect to the director via bconsole which at sometimes I can't
558 5. Another most important feature that is missing, say at 10am I manually
559 started backup of client abc and it was a full backup since client abc has
560 no backup history and at 10.30am bacula again automatically started backup of
561 client abc as that was in the schedule. So now we have 2 multiple Full
562 backups of the same client and if we again try to start a full backup of
563 client backup abc bacula won't complain. That should be fixed.
565 - For Windows disaster recovery see http://unattended.sf.net/
566 - regardless of the retention period, Bacula will not prune the
567 last Full, Diff, or Inc File data until a month after the
568 retention period for the last Full backup that was done.
569 - update volume=xxx --- add status=Full
570 - Remove old spool files on startup.
571 - Exclude SD spool/working directory.
572 - Refuse to prune last valid Full backup. Same goes for Catalog.
574 - Make a callback when Rerun failed levels is called.
575 - Give Python program access to Scheduled jobs.
576 - Add setting Volume State via Python.
577 - Python script to save with Python, not save, save with Bacula.
578 - Python script to do backup.
580 - Change the Priority, Client, Storage, JobStatus (error)
581 at the start of a job.
582 - Why is SpoolDirectory = /home/bacula/spool; not reported
583 as an error when writing a DVD?
584 - Make bootstrap file handle multiple MediaTypes (SD)
585 - Remove all old Device resource code in Dir and code to pass it
586 back in SD -- better, rework it to pass back device statistics.
587 - Check locking of resources -- be sure to lock devices where previously
588 resources were locked.
589 - The last part is left in the spool dir.
592 - In restore don't compare byte count on a raw device -- directory
593 entry does not contain bytes.
596 - Max Vols limit in Pool off by one?
597 - Implement Files/Bytes,... stats for restore job.
598 - Implement Total Bytes Written, ... for restore job.
599 - Despool attributes simultaneously with data in a separate
600 thread, rejoined at end of data spooling.
601 - 7. Implement new Console commands to allow offlining/reserving drives,
602 and possibly manipulating the autochanger (much asked for).
603 - Add start/end date editing in messages (%t %T, %e?) ...
604 - Add ClientDefs similar to JobDefs.
605 - Print more info when bextract -p accepts a bad block.
606 - Fix FD JobType to be set before RunBeforeJob in FD.
607 - Look at adding full Volume and Pool information to a Volume
608 label so that bscan can get *all* the info.
609 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
610 and there is only one volume in the pool, refuse to do it -- otherwise
611 he fills the Volume, then immediately starts reusing it.
612 - Implement copies and stripes.
613 - Add history file to console.
614 - Each file on tape creates a JobMedia record. Peter has 4 million
615 files spread over 10000 tape files and four tapes. A restore takes
616 16 hours to build the restore list.
617 - Add and option to check if the file size changed during backup.
618 - Make sure SD deletes spool files on error exit.
619 - Delete old spool files when SD starts.
620 - When labeling tapes, if you enter 000026, Bacula uses
621 the tape index rather than the Volume name 000026.
622 - Add offline tape command to Bacula console.
624 Enter MediaId or Volume name: 32
625 Enter new Volume name: DLT-20Dec04
626 Automatically selected Pool: Default
627 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

629 block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
630 Error writing final EOF to tape. This tape may not be readable.
631 dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
632 askdir.c:219 NULL Volume name. This shouldn't happen!!!
633 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
634 Label command failed for Volume DLT-20Dec04.
635 Do not forget to mount the drive!!!
636 - Bug: if a job is manually scheduled to run later, it does not appear
637 in any status report and cannot be cancelled.
642 How about introducing a Type = MgmtPolicy job type? That job type would
643 be responsible for scanning the Bacula environment looking for specific
644 conditions, and submitting the appropriate jobs for implementing said
648 Name = "Migration-Policy"
650 Policy Selection Job Type = Migrate
651 Scope = "<keyword> <operator> <regexp>"
652 Threshold = "<keyword> <operator> <regexp>"
653 Job Template = <template-name>
656 Where <keyword> is any legal job keyword, <operator> is a comparison
657 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
658 appropriate regexp. I could see an argument for Scope and Threshold
659 being SQL queries if we want to support full flexibility. The
660 Migration-Policy job would then get scheduled as frequently as a site
661 felt necessary (suggested default: every 15 minutes).
666 Name = "Migration-Policy"
668 Policy Selection Job Type = Migration
670 Threshold = "Migration Selection Type = LowestUtil"
671 Job Template = "MigrationTemplate"
674 would select all pools for examination and generate a job based on
675 MigrationTemplate to automatically select the volume with the lowest
676 usage and migrate it's contents to the nextpool defined for that pool.
678 This policy abstraction would be really handy for adjusting the behavior
679 of Bacula according to site-selectable criteria (one thing that pops
680 into mind is Amanda's ability to automatically adjust backup levels
681 depending on various criteria).
687 - Add Pool/Storage override regression test.
688 - Add delete JobId to regression.
689 - Add a regression test for dbcheck.
690 - New test to add bscan to four-concurrent-jobs regression,
691 i.e. after the four-concurrent jobs zap the
692 database as is done in the bscan-test, then use bscan to
693 restore the database, do a restore and compare with the
695 - Add restore of specific JobId to regression (item 3
696 on the restore prompt)
697 - Add IPv6 to regression
698 - Add database test to regression. Test each function like delete,
701 - AntiVir can slow down backups on Win32 systems.
702 - Win32 systems with FAT32 can be much slower than NTFS for
703 more than 1000 files per directory.
707 - A HOLD command to stop all jobs from starting.
708 - A PAUSE command to pause all running jobs ==> release the
710 - Media Type = LTO,LTO-2,LTO-3
711 Media Type Read = LTO,LTO2,LTO3
712 Media Type Write = LTO2, LTO3
714 === From Carsten Menke <bootsy52@gmx.net>
716 Following is a list of what I think in the situations where I'm faced with,
717 could be a usefull enhancement to bacula, which I'm certain other users will
718 benefit from as well.
720 1. NextJob/NextJobs Directive within a Job Resource in the form of
721 NextJobs = job1,job2.
724 I currently solved the problem with running multiple jobs each after each
725 by setting the Max Wait Time for a job to 8 hours, and give
726 the jobs different Priorities. However, there scenarios where
727 1 Job is directly depending on another job, so if the former job fails,
728 the job after it needn't to be run
729 while maybe other jobs should run despite of that
732 A Backup Job and a Verify job, if the backup job fails there is no need to run
733 the verify job, as the backup job already failed. However, one may like
734 to backup the Catalog to disk despite of that the main backup job failed.
737 I see that this is related to the Event Handlers which are on the ToDo
738 list, also it is maybe a good idea to check for the return value and
739 execute different actions based on the return value
742 3. offline capability to bconsole
745 Currently I use a script which I execute within the last Job via the
746 RunAfterJob Directive, to release and eject the tape.
747 So I have to call bconsole "release=Storage-Name" and afterwards
748 mt -f /dev/nst0 eject to get the tape out.
750 If I have multiple Storage Devices, than these may not be /dev/nst0 and
751 I have to modify the script or call it with parameters etc.
752 This would actually not be needed, as everything is already defined
753 in bacula-sd.conf and if I can invoke bconsole with the
754 storage name via $1 in the script than I'm done and information is
757 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
761 For the reason mentioned in 3. to have the ability to call a
762 script with /scripts/foobar %s and in the script use $1
763 to pass the Storage Name to bconsole
765 5. Setting Volume State within a Job Resource
768 Instead of using "Maximum Volume Jobs" in the Pool Resource,
769 I would have the possibilty to define
770 in a Job Resource that after this certain job is run, the Volume State
771 should be set to "Volume State = Used", this give more flexibility (IMHO).
773 6. Localization of Bacula Messages
776 Unfortunatley many,many people I work with don't speak english very well.
777 So if at least the Reporting messages would be localized then they
778 would understand that they have to change the tape,etc. etc.
780 I volunteer to do the german translations, and if I can convince my wife also
781 french and Morre (western african language).
783 7. OK, this is evil, probably bound to security risks and maybe not possible
784 due to the design of bacula.
786 Implementation of Backtics ( `command` ) for shell comand execution to
787 the "Label Format" Directive.
791 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
792 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
793 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
794 the localized name for the day of the week appended to the
795 format string. Then I have the tape labeled automatically with weekday
796 name in the correct language.
798 - Make output from status use html table tags for nicely
799 presenting in a browser.
800 - Browse generations of files.
801 - I've seen an error when my catalog's File table fills up. I
802 then have to recreate the File table with a larger maximum row
803 size. Relevant information is at
804 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
805 "Installing and Configuring MySQL" chapter should talk a bit
806 about this potential problem, and recommend a solution.
807 - For Solaris must use POSIX awk.
808 - Want speed of writing to tape while despooling.
809 - Supported autochanger:
817 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
818 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
819 - Add regex from http://www.pcre.org to Bacula for Win32.
820 - Use only shell tools no make in CDROM package.
821 - Include within include does it work?
822 - Implement a Pool of type Cleaning?
823 - Implement VolReadTime and VolWriteTime in SD
824 - Modify Backing up Your Database to include a bootstrap file.
825 - Think about making certain database errors fatal.
826 - Look at correcting the time jump in the scheduler for daylight
827 savings time changes.
828 - Add a "real" timer to network connections.
829 - Promote to Full = Time period
830 - Check dates entered by user for correctness (month/day/... ranges)
831 - Compress restore Volume listing by date and first file.
832 - Look at patches/bacula_db.b2z postgresql that loops during restore.
834 - Perhaps add read/write programs and/or plugins to FileSets.
835 - How to handle backing up portables ...
836 - Add some sort of guaranteed Interval for upgrading jobs.
837 - Can we write the state file after every job terminates? On Win32
838 the system crashes and the state file is not updated.
841 Documentation to do: (any release a little bit at a time)
842 - Doc to do unmount before removing magazine.
843 - Alternative to static linking "ldd prog" save all binaries listed,
844 restore them and point LD_LIBRARY_PATH to them.
845 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
846 - Document query file format.
847 - Add more documentation for bsr files.
848 - Document problems with Verify and pruning.
849 - Document how to use multiple databases.
850 - VXA drives have a "cleaning required"
851 indicator, but Exabyte recommends preventive cleaning after every 75
854 In this context, it should be noted that Exabyte has a command-line
855 vxatool utility available for free download. (The current version is
856 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
857 test the drive, unload tapes, change drive settings, flash new firmware,
859 Of particular interest in this context is that vxatool <device> -i will
860 report, among other details, the time since last cleaning in tape motion
861 minutes. This information can be retrieved (and settings changed, for
862 that matter) through the generic-SCSI device even when Bacula has the
863 regular tape device locked. (Needless to say, I don't recommend
864 changing tape settings while a job is running.)
865 - Lookup HP cleaning recommendations.
866 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
867 - Document doing table repair
870 ===================================
871 - Add macro expansions in JobDefs.
872 Run Before Job = "SomeFile %{Level} %{Client}"
873 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
874 - Use non-blocking network I/O but if no data is available, use
876 - Use gather write() for network I/O.
877 - Autorestart on crash.
878 - Add bandwidth limiting.
879 - When an error in input occurs and conio beeps, you can back
880 up through the prompt.
881 - Detect fixed tape block mode during positioning by looking at
882 block numbers in btape "test". Possibly adjust in Bacula.
883 - Fix list volumes to output volume retention in some other
884 units, perhaps via a directive.
885 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
886 with multiple priorities.
887 - If you use restore replace=never, the directory attributes for
888 non-existent directories will not be restored properly.
890 - see lzma401.zip in others directory for new compression
892 - Allow the user to select JobType for manual pruning/purging.
893 - bscan does not put first of two volumes back with all info in
895 - Figure out how to make named console messages go only to that
896 console and to the non-restricted console (new console class?).
897 - Make restricted console prompt for password if *ask* is set or
898 perhaps if password is undefined.
899 - Implement "from ISO-date/time every x hours/days/weeks/months" in
902 ==== from Marc Schoechlin
903 - the help-command should be more verbose
904 (it should explain the paramters of the different
906 -> its time-comsuming to consult the manual anytime
907 you need a special parameter
908 -> maybe its more easy to maintain this, if the
909 descriptions of that commands are outsourced to
911 - if the password is not configured in bconsole.conf
912 you should be asked for it.
913 -> sometimes you like to do restore on a customer-machine
914 which shouldnt know the password for bacula.
915 -> adding the password to the file favours admins
916 to forget to remove the password after usage
918 the protection of that file is less important
919 - long-listed-output of commands should be scrollable
920 like the unix more/less-command does
921 -> if someone runs 200 and more machines, the lists could
922 be a little long and complex
923 - command-output should be shown column by column
924 to reduce scrolling and to increase clarity
926 - lsmark should list the selected files with full
928 - wildcards for selecting and file and directories would be nice
929 - any actions should be interuptable with STRG+C
930 - command-expansion would be pretty cool
932 - When the replace Never option is set, new directory permissions
933 are not restored. See bug 213. To fix this requires creating a
934 list of newly restored directories so that those directory
935 permissions *can* be restored.
936 - Add prune all command
937 - Document fact that purge can destroy a part of a restore by purging
938 one volume while others remain valid -- perhaps mark Jobs.
939 - Add multiple-media-types.txt
940 - look at mxt-changer.html
941 - Make ? do a help command (no return needed).
942 - Implement restore directory.
943 - Document streams and how to implement them.
944 - Try not to re-backup a file if a new hard link is added.
945 - Add feature to backup hard links only, but not the data.
946 - Fix stream handling to be simpler.
947 - Add Priority and Bootstrap to Run a Job.
948 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
950 - Remove View FileSet button from Run a Job dialog.
951 - Handle prompt for restore job at end of Restore command.
952 - Add display of total selected files to Restore window.
953 - Add tree pane to left of window.
954 - Add progress meter.
955 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
956 - Add message to user to check for fixed block size when the forward
957 space test fails in btape.
958 - When unmarking a directory check if all files below are unmarked and
959 then remove the + flag -- in the restore tree.
960 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
961 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
962 - Revisit the question of multiple Volumes (disk) on a single device.
963 - Add a block copy option to bcopy.
964 - Fix "llist jobid=xx" where no fileset or client exists.
965 - For each job type (Admin, Restore, ...) require only the really necessary
966 fields.- Pass Director resource name as an option to the Console.
967 - Add a "batch" mode to the Console (no unsolicited queries, ...).
968 - Allow browsing the catalog to see all versions of a file (with
969 stat data on each file).
970 - Restore attributes of directory if replace=never set but directory
972 - Use SHA1 on authentication if possible.
973 - See comtest-xxx.zip for Windows code to talk to USB.
974 - Add John's appended files:
975 Appended = { /files/server/logs/http/*log }
976 and such files would be treated as follows.On a FULL backup, they would
977 be backed up like any other file.On an INCREMENTAL backup, where a
978 previous INCREMENTAL or FULL was already in thecatalogue and the length
979 of the file wasgreater than the length of the last backup, only thedata
980 added since the last backup will be dumped.On an INCREMENTAL backup, if
981 the length of the file is less than thelength of the file with the same
982 name last backed up, the completefile is dumped.On Windows systems, with
983 creation date of files, we can be evensmarter about this and not count
984 entirely upon the length.On a restore, the full and all incrementals
985 since it will beapplied in sequence to restore the file.
986 - Check new HAVE_WIN32 open bits.
987 - Check if the tape has moved before writing.
988 - Handling removable disks -- see below:
989 - Add FromClient and ToClient keywords on restore command (or
990 BackupClient RestoreClient).
991 - Implement a JobSet, which groups any number of jobs. If the
992 JobSet is started, all the jobs are started together.
993 Allow Pool, Level, and Schedule overrides.
994 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
995 correctly for multiple simultaneous jobs.
996 - Implement the Media record flag that indicates that the Volume does disk
998 - Implement VolAddr, which is used when Volume is addressed like a disk,
999 and form it from VolFile and VolBlock.
1000 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1001 pointer (rec) to try_repositioning().
1002 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1003 which would take precidence over the Catalog "JobRetention".
1004 - Implement Label Format in Add and Label console commands.
1005 - Put email tape request delays on one or more variables. User wants
1006 to cancel the job after a certain time interval. Maximum Mount Wait?
1007 - Job, Client, Device, Pool, or Volume?
1008 Is it possible to make this a directive which is *optional* in multiple
1009 resources, like Level? If so, I think I'd make it an optional directive
1010 in Job, Client, and Pool, with precedence such that Job overrides Client
1011 which in turn overrides Pool.
1013 - New Storage specifications:
1014 - Want to write to multiple storage devices simultaneously
1015 - Want to write to multiple storage devices sequentially (in one job)
1016 - Want to read/write simultaneously
1017 - Key is MediaType -- it must match
1019 Passed to SD as a sort of BSR record called Storage Specification
1023 MediaType -> Next MediaType
1025 Device -> Next Device
1027 Allow multiple Storage specifications
1035 Allow Multiple Pool specifications (note, Pool currently
1037 Allow Multiple MediaType specifications in Dir conf
1038 Allow Multiple Device specifications in Dir conf
1039 Perhaps keep this in a single SSR
1040 Tie a Volume to a specific device by using a MediaType that
1041 is contained in only one device.
1042 In SD allow Device to have Multiple MediaTypes
1044 - Ideas from Jerry Scharf:
1045 First let's point out some big pluses that bacula has for this
1047 more importantly it's active. Thank you so much for that
1048 even more important, it's not flaky
1049 it has an open access catalog, opening many possibilities
1050 it's pushing toward heterogeneous systems capability
1052 Macintosh file client
1053 macs are an interesting niche, but I fear a server is a rathole
1054 working bare iron recovery for windows
1055 the option for inc/diff backups not reset on fileset revision
1056 a) use both change and inode update time against base time
1057 b) do the full catalog check (expensive but accurate)
1058 sizing guide (how much system is needed to back up N systems/files)
1059 consultants on using bacula in building a disaster recovery system
1060 an integration guide
1061 or how to get at fancy things that one could do with bacula
1062 logwatch code for bacula logs (or similar)
1063 linux distro inclusion of bacula (brings good and bad, but necessary)
1064 win2k/XP server capability (icky but you asked)
1065 support for Oracle database ??
1067 - Look at adding SQL server and Exchange support for Windows.
1068 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1069 is needed to properly specify ranges.
1070 - Add progress of files/bytes to SD and FD.
1071 - Print warning message if FileId > 4 billion
1072 - do a "messages" before the first prompt in Console
1073 - Client does not show busy during Estimate command.
1074 - Implement Console mtx commands.
1075 - Implement a Mount Command and an Unmount Command where
1076 the users could specify a system command to be performed
1077 to do the mount, after which Bacula could attempt to
1078 read the device. This is for Removeable media such as a CDROM.
1079 - Most likely, this mount command would be invoked explicitly
1080 by the user using the current Console "mount" and "unmount"
1081 commands -- the Storage Daemon would do the right thing
1082 depending on the exact nature of the device.
1083 - As with tape drives, when Bacula wanted a new removable
1084 disk mounted, it would unmount the old one, and send a message
1085 to the user, who would then use "mount" as described above
1086 once he had actually inserted the disk.
1087 - Implement dump/print label to UA
1088 - Spool to disk only when the tape is full, then when a tape is hung move
1090 - bextract is sending everything to the log file ****FIXME****
1091 - Allow multiple Storage specifications (or multiple names on
1092 a single Storage specification) in the Job record. Thus a job
1093 can be backed up to a number of storage devices.
1094 - Implement some way for the File daemon to contact the Director
1095 to start a job or pass its DHCP obtained IP number.
1096 - Implement a query tape prompt/replace feature for a console
1097 - Make sure that Bacula rechecks the tape after the 20 min wait.
1098 - Set IO_NOWAIT on Bacula TCP/IP packets.
1099 - Try doing a raw partition backup and restore by mounting a
1101 - From Lars Kellers:
1102 Yes, it would allow to highly automatic the request for new tapes. If a
1103 tape is empty, bacula reads the barcodes (native or simulated), and if
1104 an unused tape is found, it runs the label command with all the
1105 necessary parameters.
1107 By the way can bacula automatically "move" an empty/purged volume say
1108 in the "short" pool to the "long" pool if this pool runs out of volume
1110 - What to do about "list files job=xxx".
1111 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1112 file descriptor leak in Bacula.
1113 - Can we dynamically change FileSets?
1114 - If pool specified to label command and Label Format is specified,
1115 automatically generate the Volume name.
1116 - Add ExhautiveRestoreSearch
1117 - Look at the possibility of loading only the necessary
1118 data into the restore tree (i.e. do it one directory at a
1119 time as the user walks through the tree).
1120 - Possibly use the hash code if the user selects all for a restore command.
1121 - Fix "restore all" to bypass building the tree.
1122 - Prohibit backing up archive device (findlib/find_one.c:128)
1123 - Implement Release Device in the Job resource to unmount a drive.
1124 - Implement Acquire Device in the Job resource to mount a drive,
1125 be sure this works with admin jobs so that the user can get
1126 prompted to insert the correct tape. Possibly some way to say to
1127 run the job but don't save the files.
1128 - Make things like list where a file is saved case independent for
1130 - Implement a Recycle command
1131 - Start working on Base jobs.
1132 - From Phil Stracchino:
1133 It would probably be a per-client option, and would be called
1134 something like, say, "Automatically purge obsoleted jobs". What it
1135 would do is, when you successfully complete a Differential backup of a
1136 client, it would automatically purge all Incremental backups for that
1137 client that are rendered redundant by that Differential. Likewise,
1138 when a Full backup on a client completed, it would automatically purge
1139 all Differential and Incremental jobs obsoleted by that Full backup.
1140 This would let people minimize the number of tapes they're keeping on
1141 hand without having to master the art of retention times.
1142 - When doing a Backup send all attributes back to the Director, who
1143 would then figure out what files have been deleted.
1144 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1145 explicit permission to do so. It should also mark the tape in error
1146 if there is an error.
1147 - Cancel waiting for Client connect in SD if FD goes away.
1149 - Implement timeout in response() when it should come quickly.
1150 - Implement a Slot priority (loaded/not loaded).
1151 - Implement "vacation" Incremental only saves.
1152 - Implement create "FileSet"?
1153 - Add prefixlinks to where or not where absolute links to FD.
1154 - Issue message to mount a new tape before the rewind.
1155 - Simplified client job initiation for portables.
1156 - If SD cannot open a drive, make it periodically retry.
1157 - Add more of the config info to the tape label.
1159 - Refine SD waiting output:
1160 Device is being positioned
1161 > Device is being positioned for append
1162 > Device is being positioned to file x
1164 - Figure out some way to estimate output size and to avoid splitting
1165 a backup across two Volumes -- this could be useful for writing CDROMs
1166 where you really prefer not to have it split -- not serious.
1167 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1168 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1169 actual data on the Volume and compare it.
1170 - Make bcopy read through bad tape records.
1171 - Program files (i.e. execute a program to read/write files).
1172 Pass read date of last backup, size of file last time.
1173 - Add Signature type to File DB record.
1174 - CD into subdirectory when open()ing files for backup to
1175 speed up things. Test with testfind().
1176 - Priority job to go to top of list.
1177 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1178 - Implement some way for the Console to dynamically create a job.
1179 - Solaris -I on tar for include list
1180 - Need a verbose mode in restore, perhaps to bsr.
1181 - bscan without -v is too quiet -- perhaps show jobs.
1182 - Add code to reject whole blocks if not wanted on restore.
1183 - Check if we can increase Bacula FD priorty in Win2000
1184 - Check if both CatalogFiles and UseCatalog are set to SD.
1185 - Possibly add email to Watchdog if drive is unmounted too
1186 long and a job is waiting on the drive.
1187 - After unmount, if restore job started, ask to mount.
1188 - Add UA rc and history files.
1189 - put termcap (used by console) in ./configure and
1190 allow -with-termcap-dir.
1191 - Fix Autoprune for Volumes to respect need for full save.
1192 - Compare tape to Client files (attributes, or attributes and data)
1193 - Make all database Ids 64 bit.
1194 - Allow console commands to detach or run in background.
1195 - Add SD message variables to control operator wait time
1196 - Maximum Operator Wait
1197 - Minimum Message Interval
1198 - Maximum Message Interval
1199 - Send Operator message when cannot read tape label.
1200 - Verify level=Volume (scan only), level=Data (compare of data to file).
1201 Verify level=Catalog, level=InitCatalog
1203 - Add keyword search to show command in Console.
1204 - Events : tape has more than xxx bytes.
1205 - Complete code in Bacula Resources -- this will permit
1206 reading a new config file at any time.
1207 - Handle ctl-c in Console
1208 - Implement script driven addition of File daemon to config files.
1209 - Think about how to make Bacula work better with File (non-tape) archives.
1210 - Write Unix emulator for Windows.
1211 - Make database type selectable by .conf files i.e. at runtime
1212 - Set flag for uname -a. Add to Volume label.
1213 - Restore files modified after date
1214 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1215 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1216 - Timout a job or terminate if link goes down, or reopen link and query.
1217 - Concept of precious tapes (cannot be reused).
1218 - Make bcopy copy with a single tape drive.
1219 - Permit changing ownership during restore.

1233 - Autolabel should be specified by DIR instead of SD.
1235 - Add media capacity
1236 - AutoScan (check checksum of tape)
1237 - Format command = "format /dev/nst0"
1241 - Seek resolution (usually corresponds to buffer size)
1242 - EODErrorCode=ENOSPC or code
1243 - Partial Read error code
1244 - Partial write error code
1245 - Nonformatted read error
1246 - Nonformatted write error
1247 - WriteProtected error
1251 - IgnoreCloseErrors=yes
1261 - Write a Storage daemon that uses pipes and
1262 standard Unix programs to write to the tape.
1264 - Need something that monitors the JCR queue and
1265 times out jobs by asking the deamons where they are.
1266 - Enhance Jmsg code to permit buffering and saving to disk.
1267 - Verify from Volume
1268 - Need report class for messages. Perhaps
1269 report resource where report=group of messages
1270 - enhance scan_attrib and rename scan_jobtype, and
1271 fill in code for "since" option
1272 - Director needs a time after which the report status is sent
1273 anyway -- or better yet, a retry time for the job.
1274 - Don't reschedule a job if previous incarnation is still running.
1275 - Some way to automatically backup everything is needed????
1276 - Need a structure for pending actions:
1278 - termination status (part of buffered msgs?)
1280 Read, Write, Clean, Delete
1281 - Login to Bacula; Bacula users with different permissions:
1282 owner, group, user, quotas
1283 - Store info on each file system type (probably in the job header on tape.
1284 This could be the output of df; or perhaps some sort of /etc/mtab record.

1287 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1288 To: <kern@sibbald.com>
1289 Subject: RE: [Bacula-users] future large programming jobs
1290 Date: Thu, 26 Feb 2004 11:34:54 -0600
1292 I noticed the subject thread and thought I would offer the following
1293 merely as sources of ideas, i.e. something to think about, not even as
1294 strong as a request. In my former life (before retiring) I often
1295 dealt with backups and storage management issues/products as a
1296 developer and as a consultant. I am currently migrating my personal
1297 network from amanda to bacula specifically because of the ability to
1298 cross media boundaries during storing backups.
1299 Are you familiar with the commercial product called ADSM (I think IBM
1300 now sells it under the Tivoli label)? It has a couple of interesting
1301 ideas that may apply to the following topics.
1303 1. Migration: Consider that when you need to restore a system, there
1304 may be pressure to hurry. If all the information for a single client
1305 can eventually end up on the same media (and in chronological order),
1306 the restore is facillitated by not having to search past information
1307 from other clients. ADSM has the concept of "client affinity" that
1308 may be associated with it's storage pools. It seems to me that this
1309 concept (as an optional feature) might fit in your architecture for
1312 ADSM also has the concept of defining one or more storage pools as
1313 "copy pools" (almost mirrors, but only in the sense of contents).
1314 These pools provide the ability to have duplicte data stored both
1315 onsite and offsite. The copy process can be scheduled to be handled
1316 by their storage manager during periods when there is no backup
1317 activity. Again, the migration process might be a place to consider
1318 implementing something like this.
1321 > It strikes me that it would be very nice to be able to do things

1329 > mechanism described below would probably make it very easy.
1331 This is the goal. In the first step (before events), you simply
1333 the Migration to tape later.
1335 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1336 the database. Once a file (unique by path and metadata such as dates,
1337 size, ownership, etc.) is in a copy pool, no more copies are made. In
1338 other words, when you start ADSM, it begins like your concept of a
1339 base job. After that it is in the "incremental" mode. You can
1340 configure the number of "generations" of files to be retained, plus a
1341 retention date after which even old generations are purged. The
1342 database tracks the contents of media and projects the percentage of
1343 each volume that is valid. When the valid content of a volume drops
1344 below a configured percentage, the valid data are migrated to another
1345 volume and the old volume is marked as empty. Note, this requires
1346 ADSM to have an idea of the contents of a client, i.e. marking the
1347 database when an existing file was deleted, but this would solve your
1348 issue of restoring a client without restoring deleted files.
1350 This is pretty far from what bacula now does, but if you are going to
1351 rip things up for Base jobs,.....
1352 Also, the benefits of this are huge for very large shops, especially
1353 with media robots, but are a pain for shops with manual media
1357 > Base jobs sound pretty useful, but I'm not dying for them.
1359 Nobody is dying for them, but when you see what it does, you will die
1365 ==============================
1368 - Implement FSM (File System Modules).
1369 - Audit M_ error codes to ensure they are correct and consistent.
1370 - Add variable break characters to lex analyzer.
1371 Either a bit mask or a string of chars so that
1372 the caller can change the break characters.
1373 - Make a single T_BREAK to replace T_COMMA, etc.
1374 - Ensure that File daemon and Storage daemon can
1375 continue a save if the Director goes down (this
1376 is NOT currently the case). Must detect socket error,
1377 buffer messages for later.
1378 - Add ability to backup to two Storage devices (two SD sessions) at
1379 the same time -- e.g. onsite, offsite.
1381 ======================================================
1383 It is somewhat like a Full save becomes an incremental since
1384 the Base job (or jobs) plus other non-base files.
1386 - A Base backup is same as Full backup, just different type.
1387 - New BaseFiles table that contains:
1389 BaseJobId - Base JobId referenced for this FileId (needed ???)
1390 JobId - JobId currently running
1391 FileId - File not backed up, exists in Base Job
1392 FileIndex - FileIndex from Base Job.
1393 i.e. for each base file that exists but is not saved because
1394 it has not changed, the File daemon sends the JobId, BaseId,
1395 FileId, FileIndex back to the Director who creates the DB entry.
1396 - To initiate a Base save, the Director sends the FD
1397 the FileId, and full filename for each file in the Base.
1398 - When the FD finds a Base file, he requests the Director to
1399 send him the full File entry (stat packet plus MD5), or
1400 conversely, the FD sends it to the Director and the Director
1401 says yes or no. This can be quite rapid if the FileId is kept
1402 by the FD for each Base Filename.
1403 - It is probably better to have the comparison done by the FD
1404 despite the fact that the File entry must be sent across the
1406 - An alternative would be to send the FD the whole File entry
1407 from the start. The disadvantage is that it requires a lot of
1408 space. The advantage is that it requires less communications
1410 - The Job record must be updated to indicate that one or more
1412 - At end of Job, FD returns:
1413 1. Count of base files/bytes not written to tape (i.e. matches)
1414 2. Count of base file that were saved i.e. had changed.
1415 - No tape record would be written for a Base file that matches, in the
1416 same way that no tape record is written for Incremental jobs where
1417 the file is not saved because it is unchanged.
1418 - On a restore, all the Base file records must explicitly be
1419 found from the BaseFile tape. I.e. for each Full save that is marked
1420 to have one or more Base Jobs, search the BaseFile for all occurrences
1422 - An optimization might be to make the BaseFile have:
1428 This would avoid the need to explicitly fetch each File record for
1429 the Base job. The Base Job record will be fetched to get the
1430 VolSessionId and VolSessionTime.

1434 Handling removable disks
1436 From: Karl Cunningham <karlc@keckec.com>
1438 My backups are only to hard disk these days, in removable bays. This is my
1439 idea of how a backup to hard disk would work more smoothly. Some of these
1440 things Bacula does already, but I mention them for completeness. If others
1441 have better ways to do this, I'd like to hear about it.
1443 1. Accommodate several disks, rotated similar to how tapes are. Identified
1444 by partition volume ID or perhaps by the name of a subdirectory.
1445 2. Abort & notify the admin if the wrong disk is in the bay.
1446 3. Write backups to different subdirectories for each machine to be backed
1448 4. Volumes (files) get created as needed in the proper subdirectory, one
1450 5. When a disk is recycled, remove or zero all old backup files. This is
1451 important as the disk being recycled may be close to full. This may be
1452 better done manually since the backup files for many machines may be
1453 scattered in many subdirectories.
1460 - Fix bpipe.c so that it does not modify results pointer.
1461 ***FIXME*** calling sequence should be changed.
