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
26 - Fix re-read of last block to check if job has actually written
27 a block, and check if block was written by a different job
28 (i.e. multiple simultaneous jobs writing).
29 - JobStatus and Termination codes.
30 - Some users claim that they must do two prune commands to get a
31 Volume marked as purged.
32 - Print warning message if LANG environment variable does not specify

45 Next Pool = <override>
48 There should be no need for a Level (migration is always Full, since you
49 don't calculate differential/incremental differences for migration),
50 Storage should be determined by the volume types in the pool, and Client
51 is really a selection issue. Migration should always occur to the
52 NextPool defined in the pool definition. If no nextpool is defined, the
53 job should end with a reason of "no place to go". If Next Pool statement
54 is present, we override the check in the pool definition and use the
57 Here's how I'd define Migration Selection Types:
60 Client -- Migrate data from selected client only. Migration Selection
61 Pattern regexp provides pattern to select client names, eg ^FS00* makes
62 all client names starting with FS00 eligible for migration.
64 Jobname -- Migration all jobs matching name. Migration Selection Pattern
65 regexp provides pattern to select jobnames existing in pool.
67 Volume -- Migrate all data on specified volumes. Migration Selection
68 Pattern regexp provides selection criteria for volumes to be migrated.
69 Volumes must exist in pool to be eligible for migration.
73 LowestUtil -- Identify the volume in the pool with the least data on it
74 and empty it. No Migration Selection Pattern required.
76 OldestVol -- Identify the LRU volume with data written, and empty it. No
77 Migration Selection Pattern required.
79 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
80 (starting with most full volumes) until pool occupancy drops below
81 <lowmig>. Pool highmig and lowmig values are in pool definition, no
82 Migration Selection Pattern required.
86 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
87 Migration Selection Pattern contains SQL query to execute; should return
88 a list of 1 or more jobuids to migrate.
90 PoolResidence -- Migrate data sitting in pool for longer than

277 - From: Arunav Mandal <amandal@trolltech.com>
278 1. When jobs are running and bacula for some reason crashes or if I do a
279 restart it remembers and jobs it was running before it crashed or restarted
280 as of now I loose all jobs if I restart it.
282 2. When spooling and in the midway if client is disconnected for instance a
283 laptop bacula completely discard the spool. It will be nice if it can write
284 that spool to tape so there will be some backups for that client if not all.
286 3. We have around 150 clients machines it will be nice to have a option to
287 upgrade all the client machines bacula version automatically.
289 4. Atleast one connection should be reserved for the bconsole so at heavy load
290 I should connect to the director via bconsole which at sometimes I can't
292 5. Another most important feature that is missing, say at 10am I manually
293 started backup of client abc and it was a full backup since client abc has
294 no backup history and at 10.30am bacula again automatically started backup of
295 client abc as that was in the schedule. So now we have 2 multiple Full
296 backups of the same client and if we again try to start a full backup of
297 client backup abc bacula won't complain. That should be fixed.
299 - Fix bpipe.c so that it does not modify results pointer.
300 ***FIXME*** calling sequence should be changed.
301 - For Windows disaster recovery see http://unattended.sf.net/
302 - regardless of the retention period, Bacula will not prune the
303 last Full, Diff, or Inc File data until a month after the
304 retention period for the last Full backup that was done.
305 - update volume=xxx --- add status=Full
306 - Remove old spool files on startup.
307 - Exclude SD spool/working directory.
308 - Refuse to prune last valid Full backup. Same goes for Catalog.
310 - Make a callback when Rerun failed levels is called.
311 - Give Python program access to Scheduled jobs.
312 - Add setting Volume State via Python.
313 - Python script to save with Python, not save, save with Bacula.
314 - Python script to do backup.
316 - Change the Priority, Client, Storage, JobStatus (error)
317 at the start of a job.
318 - Why is SpoolDirectory = /home/bacula/spool; not reported
319 as an error when writing a DVD?
320 - Make bootstrap file handle multiple MediaTypes (SD)
321 - Remove all old Device resource code in Dir and code to pass it
322 back in SD -- better, rework it to pass back device statistics.
323 - Check locking of resources -- be sure to lock devices where previously
324 resources were locked.
325 - The last part is left in the spool dir.
328 - In restore don't compare byte count on a raw device -- directory
329 entry does not contain bytes.
330 - To mark files as deleted, run essentially a Verify to disk, and
331 when a file is found missing (MarkId != JobId), then create
332 a new File record with FileIndex == -1. This could be done
333 by the FD at the same time as the backup.
337 MA = (last_MA * 3 + rate) / 4
338 rate = (bytes - last_bytes) / (runtime - last_runtime)
339 - Max Vols limit in Pool off by one?
340 - Implement Files/Bytes,... stats for restore job.
341 - Implement Total Bytes Written, ... for restore job.
342 - Despool attributes simultaneously with data in a separate
343 thread, rejoined at end of data spooling.
344 - 7. Implement new Console commands to allow offlining/reserving drives,
345 and possibly manipulating the autochanger (much asked for).
346 - Add start/end date editing in messages (%t %T, %e?) ...
347 - Add ClientDefs similar to JobDefs.
348 - Print more info when bextract -p accepts a bad block.
349 - Fix FD JobType to be set before RunBeforeJob in FD.
350 - Look at adding full Volume and Pool information to a Volume
351 label so that bscan can get *all* the info.
352 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
353 and there is only one volume in the pool, refuse to do it -- otherwise
354 he fills the Volume, then immediately starts reusing it.
355 - Implement copies and stripes.
356 - Add history file to console.
357 - Each file on tape creates a JobMedia record. Peter has 4 million
358 files spread over 10000 tape files and four tapes. A restore takes
359 16 hours to build the restore list.
360 - Add and option to check if the file size changed during backup.
361 - Make sure SD deletes spool files on error exit.
362 - Delete old spool files when SD starts.
363 - When labeling tapes, if you enter 000026, Bacula uses
364 the tape index rather than the Volume name 000026.
365 - Add offline tape command to Bacula console.
367 Enter MediaId or Volume name: 32
368 Enter new Volume name: DLT-20Dec04
369 Automatically selected Pool: Default
370 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

376 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
377 Label command failed for Volume DLT-20Dec04.
378 Do not forget to mount the drive!!!
379 - Bug: if a job is manually scheduled to run later, it does not appear
380 in any status report and cannot be cancelled.
382 ==== Keeping track of deleted files ====
383 My "trick" for keeping track of deletions is the following.
384 Assuming the user turns on this option, after all the files
385 have been backed up, but before the job has terminated, the
386 FD will make a pass through all the files and send their
387 names to the DIR (*exactly* the same as what a Verify job
388 currently does). This will probably be done at the same
389 time the files are being sent to the SD avoiding a second
390 pass. The DIR will then compare that to what is stored in
391 the catalog. Any files in the catalog but not in what the
392 FD sent will receive a catalog File entry that indicates
393 that at that point in time the file was deleted.
395 During a restore, any file initially picked up by some
396 backup (Full, ...) then subsequently having a File entry
397 marked "delete" will be removed from the tree, so will not
398 be restored. If a file with the same name is later OK it
399 will be inserted in the tree -- this already happens. All
400 will be consistent except for possible changes during the
403 Since I'm on the subject, some of you may be wondering what
404 the utility of the in memory tree is if you are going to
405 restore everything (at least it comes up from time to time
406 on the list). Well, it is still *very* useful because it
407 allows only the last item found for a particular filename
408 (full path) to be entered into the tree, and thus if a file
409 is backed up 10 times, only the last copy will be restored.
410 I recently (last Friday) restored a complete directory, and
411 the Full and all the Differential and Incremental backups
412 spanned 3 Volumes. The first Volume was not even mounted
413 because all the files had been updated and hence backed up
414 since the Full backup was made. In this case, the tree
415 saved me a *lot* of time.
417 Make sure this information is stored on the tape too so
418 that it can be restored directly from the tape.
420 Comments from Martin Simmons (I think they are all covered):
421 Ok, that should cover the basics. There are few issues though:
423 - Restore will depend on the catalog. I think it is better to include the
424 extra data in the backup as well, so it can be seen by bscan and bextract.
426 - I'm not sure if it will preserve multiple hard links to the same inode. Or
427 maybe adding or removing links will cause the data to be dumped again?
429 - I'm not sure if it will handle renamed directories. Possibly it will work
430 by dumping the whole tree under a renamed directory?
432 - It remains to be seen how the backup performance of the DIR's will be
433 affected when comparing the catalog for a large filesystem.
437 How about introducing a Type = MgmtPolicy job type? That job type would
438 be responsible for scanning the Bacula environment looking for specific
439 conditions, and submitting the appropriate jobs for implementing said
443 Name = "Migration-Policy"
445 Policy Selection Job Type = Migrate
446 Scope = "<keyword> <operator> <regexp>"
447 Threshold = "<keyword> <operator> <regexp>"
448 Job Template = <template-name>
451 Where <keyword> is any legal job keyword, <operator> is a comparison
452 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
453 appropriate regexp. I could see an argument for Scope and Threshold
454 being SQL queries if we want to support full flexibility. The
455 Migration-Policy job would then get scheduled as frequently as a site
456 felt necessary (suggested default: every 15 minutes).
461 Name = "Migration-Policy"
463 Policy Selection Job Type = Migration
465 Threshold = "Migration Selection Type = LowestUtil"
466 Job Template = "MigrationTemplate"
469 would select all pools for examination and generate a job based on
470 MigrationTemplate to automatically select the volume with the lowest
471 usage and migrate it's contents to the nextpool defined for that pool.
473 This policy abstraction would be really handy for adjusting the behavior
474 of Bacula according to site-selectable criteria (one thing that pops
475 into mind is Amanda's ability to automatically adjust backup levels
476 depending on various criteria).
482 - Add Pool/Storage override regression test.
483 - Add delete JobId to regression.
484 - Add a regression test for dbcheck.
485 - New test to add bscan to four-concurrent-jobs regression,
486 i.e. after the four-concurrent jobs zap the
487 database as is done in the bscan-test, then use bscan to
488 restore the database, do a restore and compare with the
490 - Add restore of specific JobId to regression (item 3
491 on the restore prompt)
492 - Add IPv6 to regression
493 - Add database test to regression. Test each function like delete,
496 - AntiVir can slow down backups on Win32 systems.
497 - Win32 systems with FAT32 can be much slower than NTFS for
498 more than 1000 files per directory.

503 - A PAUSE command to pause all running jobs ==> release the

509 === From Carsten Menke <bootsy52@gmx.net>
511 Following is a list of what I think in the situations where I'm faced with,
512 could be a usefull enhancement to bacula, which I'm certain other users will
513 benefit from as well.
515 1. NextJob/NextJobs Directive within a Job Resource in the form of
516 NextJobs = job1,job2.
519 I currently solved the problem with running multiple jobs each after each
520 by setting the Max Wait Time for a job to 8 hours, and give
521 the jobs different Priorities. However, there scenarios where
522 1 Job is directly depending on another job, so if the former job fails,
523 the job after it needn't to be run
524 while maybe other jobs should run despite of that
527 A Backup Job and a Verify job, if the backup job fails there is no need to run
528 the verify job, as the backup job already failed. However, one may like
529 to backup the Catalog to disk despite of that the main backup job failed.
532 I see that this is related to the Event Handlers which are on the ToDo
533 list, also it is maybe a good idea to check for the return value and
534 execute different actions based on the return value
537 3. offline capability to bconsole
540 Currently I use a script which I execute within the last Job via the
541 RunAfterJob Directive, to release and eject the tape.
542 So I have to call bconsole "release=Storage-Name" and afterwards
543 mt -f /dev/nst0 eject to get the tape out.
545 If I have multiple Storage Devices, than these may not be /dev/nst0 and
546 I have to modify the script or call it with parameters etc.
547 This would actually not be needed, as everything is already defined
548 in bacula-sd.conf and if I can invoke bconsole with the
549 storage name via $1 in the script than I'm done and information is
552 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
556 For the reason mentioned in 3. to have the ability to call a
557 script with /scripts/foobar %s and in the script use $1
558 to pass the Storage Name to bconsole
560 5. Setting Volume State within a Job Resource
563 Instead of using "Maximum Volume Jobs" in the Pool Resource,
564 I would have the possibilty to define
565 in a Job Resource that after this certain job is run, the Volume State
566 should be set to "Volume State = Used", this give more flexibility (IMHO).
568 6. Localization of Bacula Messages
571 Unfortunatley many,many people I work with don't speak english very well.
572 So if at least the Reporting messages would be localized then they
573 would understand that they have to change the tape,etc. etc.
575 I volunteer to do the german translations, and if I can convince my wife also
576 french and Morre (western african language).
578 7. OK, this is evil, probably bound to security risks and maybe not possible
579 due to the design of bacula.
581 Implementation of Backtics ( `command` ) for shell comand execution to
582 the "Label Format" Directive.
586 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
587 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
588 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
589 the localized name for the day of the week appended to the
590 format string. Then I have the tape labeled automatically with weekday
591 name in the correct language.
593 - Yes, that is surely the case. I probably should turn those into Warning
594 errors. In addition, you just made me think that it might not be bad to
595 add an option to check the file size after backing up the file and
596 report if it changes. This would be done as an option because it would
599 Kern, good idea. If you do do that, mention in the output: file
600 shrunk, or file expanded, just to make it obvious to the user
601 (without having to the refer to file size), just how the file size
604 Would this option be for all file, or just one file? Or a fileset?
605 - Make output from status use html table tags for nicely
606 presenting in a browser.
607 - Can one write tapes faster with 8192 byte block sizes?
608 - Document security problems with the same password for everyone in
609 rpm and Win32 releases.
610 - Browse generations of files.
611 - I've seen an error when my catalog's File table fills up. I
612 then have to recreate the File table with a larger maximum row
613 size. Relevant information is at
614 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
615 "Installing and Configuring MySQL" chapter should talk a bit
616 about this potential problem, and recommend a solution.
617 - For Solaris must use POSIX awk.
618 - Want speed of writing to tape while despooling.
619 - Supported autochanger:
627 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
628 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
629 - Add regex from http://www.pcre.org to Bacula for Win32.
630 - Use only shell tools no make in CDROM package.
631 - Include within include does it work?
632 - Implement a Pool of type Cleaning?
633 - Implement VolReadTime and VolWriteTime in SD
634 - Modify Backing up Your Database to include a bootstrap file.
635 - Think about making certain database errors fatal.
636 - Look at correcting the time jump in the scheduler for daylight
637 savings time changes.
638 - Add a "real" timer to network connections.
639 - Promote to Full = Time period
640 - Check dates entered by user for correctness (month/day/... ranges)
641 - Compress restore Volume listing by date and first file.
642 - Look at patches/bacula_db.b2z postgresql that loops during restore.
644 - Perhaps add read/write programs and/or plugins to FileSets.
645 - How to handle backing up portables ...
646 - Add some sort of guaranteed Interval for upgrading jobs.
647 - Can we write the state file after every job terminates? On Win32
648 the system crashes and the state file is not updated.
651 Documentation to do: (any release a little bit at a time)
652 - Doc to do unmount before removing magazine.
653 - Alternative to static linking "ldd prog" save all binaries listed,
654 restore them and point LD_LIBRARY_PATH to them.
655 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
656 - Document query file format.
657 - Add more documentation for bsr files.
658 - Document problems with Verify and pruning.
659 - Document how to use multiple databases.
660 - VXA drives have a "cleaning required"
661 indicator, but Exabyte recommends preventive cleaning after every 75
664 In this context, it should be noted that Exabyte has a command-line
665 vxatool utility available for free download. (The current version is
666 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
667 test the drive, unload tapes, change drive settings, flash new firmware,
669 Of particular interest in this context is that vxatool <device> -i will
670 report, among other details, the time since last cleaning in tape motion
671 minutes. This information can be retrieved (and settings changed, for
672 that matter) through the generic-SCSI device even when Bacula has the
673 regular tape device locked. (Needless to say, I don't recommend
674 changing tape settings while a job is running.)
675 - Lookup HP cleaning recommendations.
676 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
677 - Document doing table repair
680 ===================================
681 - Add macro expansions in JobDefs.
682 Run Before Job = "SomeFile %{Level} %{Client}"
683 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
684 - Use non-blocking network I/O but if no data is available, use
686 - Use gather write() for network I/O.
687 - Autorestart on crash.
688 - Add bandwidth limiting.
689 - Add acks every once and a while from the SD to keep
690 the line from timing out.
691 - When an error in input occurs and conio beeps, you can back
692 up through the prompt.
693 - Detect fixed tape block mode during positioning by looking at
694 block numbers in btape "test". Possibly adjust in Bacula.
695 - Fix list volumes to output volume retention in some other
696 units, perhaps via a directive.
697 - If opening a tape in read/write mode fails attempt to open
698 it in read-only mode, and mark the tape for read only.
699 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
700 with multiple priorities.
701 - If you use restore replace=never, the directory attributes for
702 non-existent directories will not be restored properly.
704 - see lzma401.zip in others directory for new compression
706 - Minimal autochanger handling in Bacula and in btape.
707 - Look into how tar does not save sockets and the possiblity of
708 not saving them in Bacula (Martin Simmons reported this).
709 - Fix restore jobs so that multiple jobs can run if they
710 are not using the same tape(s).
711 - Allow the user to select JobType for manual pruning/purging.
712 - bscan does not put first of two volumes back with all info in
714 - Implement the FreeBSD nodump flag in chflags.
715 - Figure out how to make named console messages go only to that
716 console and to the non-restricted console (new console class?).
717 - Make restricted console prompt for password if *ask* is set or
718 perhaps if password is undefined.
719 - Implement "from ISO-date/time every x hours/days/weeks/months" in
722 ==== from Marc Schoechlin
723 - the help-command should be more verbose
724 (it should explain the paramters of the different
726 -> its time-comsuming to consult the manual anytime
727 you need a special parameter
728 -> maybe its more easy to maintain this, if the
729 descriptions of that commands are outsourced to
731 - the cd-command should allow complete paths
732 i.e. cd /foo/bar/foo/bar
733 -> if a customer mails me the path to a certain file,
734 its faster to enter the specified directory
735 - if the password is not configured in bconsole.conf
736 you should be asked for it.
737 -> sometimes you like to do restore on a customer-machine
738 which shouldnt know the password for bacula.
739 -> adding the password to the file favours admins
740 to forget to remove the password after usage
742 the protection of that file is less important
743 - long-listed-output of commands should be scrollable
744 like the unix more/less-command does
745 -> if someone runs 200 and more machines, the lists could
746 be a little long and complex
747 - command-output should be shown column by column
748 to reduce scrolling and to increase clarity
750 - lsmark should list the selected files with full
752 - wildcards for selecting and file and directories would be nice
753 - any actions should be interuptable with STRG+C
754 - command-expansion would be pretty cool
756 - When the replace Never option is set, new directory permissions
757 are not restored. See bug 213. To fix this requires creating a
758 list of newly restored directories so that those directory
759 permissions *can* be restored.
760 - Compaction of Disk space by "migrating" Volumes that have pruned
761 Jobs (what criteria? size, #jobs, time).
762 - Add prune all command
763 - Document fact that purge can destroy a part of a restore by purging
764 one volume while others remain valid -- perhaps mark Jobs.
765 - Add multiple-media-types.txt
766 - look at mxt-changer.html
767 - Make ? do a help command (no return needed).
768 - Implement restore directory.
769 - Document streams and how to implement them.
770 - Try not to re-backup a file if a new hard link is added.
771 - Add feature to backup hard links only, but not the data.
772 - Fix stream handling to be simpler.
773 - Add Priority and Bootstrap to Run a Job.
774 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
776 - Remove View FileSet button from Run a Job dialog.
777 - Handle prompt for restore job at end of Restore command.
778 - Add display of total selected files to Restore window.
779 - Add tree pane to left of window.
780 - Add progress meter.
781 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
782 - Document writing to a CD/DVD with Bacula.
783 - Add a "base" package to the window installer for pthreadsVCE.dll
784 which is needed by all packages.
785 - Add message to user to check for fixed block size when the forward
786 space test fails in btape.
787 - When unmarking a directory check if all files below are unmarked and
788 then remove the + flag -- in the restore tree.
789 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
790 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
791 - Revisit the question of multiple Volumes (disk) on a single device.
792 - Add a block copy option to bcopy.
793 - Investigate adding Mac Resource Forks.
794 - Finish work on Gnome restore GUI.
795 - Fix "llist jobid=xx" where no fileset or client exists.
796 - For each job type (Admin, Restore, ...) require only the really necessary
797 fields.- Pass Director resource name as an option to the Console.
798 - Add a "batch" mode to the Console (no unsolicited queries, ...).
799 - Add a .list all files in the restore tree (probably also a list all files)
800 Do both a long and short form.
801 - Allow browsing the catalog to see all versions of a file (with
802 stat data on each file).
803 - Restore attributes of directory if replace=never set but directory
805 - Use SHA1 on authentication if possible.
806 - See comtest-xxx.zip for Windows code to talk to USB.
807 - Add John's appended files:
808 Appended = { /files/server/logs/http/*log }
809 and such files would be treated as follows.On a FULL backup, they would
810 be backed up like any other file.On an INCREMENTAL backup, where a
811 previous INCREMENTAL or FULL was already in thecatalogue and the length
812 of the file wasgreater than the length of the last backup, only thedata
813 added since the last backup will be dumped.On an INCREMENTAL backup, if
814 the length of the file is less than thelength of the file with the same
815 name last backed up, the completefile is dumped.On Windows systems, with
816 creation date of files, we can be evensmarter about this and not count
817 entirely upon the length.On a restore, the full and all incrementals
818 since it will beapplied in sequence to restore the file.
819 - Check new HAVE_WIN32 open bits.
820 - Check if the tape has moved before writing.
821 - Handling removable disks -- see below:
822 - Keep track of tape use time, and report when cleaning is necessary.
823 - Add FromClient and ToClient keywords on restore command (or
824 BackupClient RestoreClient).
825 - Implement a JobSet, which groups any number of jobs. If the
826 JobSet is started, all the jobs are started together.
827 Allow Pool, Level, and Schedule overrides.
828 - Enhance cancel to timeout BSOCK packets after a specific delay.
829 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
830 ua_status.!!! Thanks to Alan Brown for this tip.
831 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
832 correctly for multiple simultaneous jobs.
833 - Correct code so that FileSet MD5 is calculated for < and | filename
835 - Implement the Media record flag that indicates that the Volume does disk
837 - Implement VolAddr, which is used when Volume is addressed like a disk,
838 and form it from VolFile and VolBlock.
839 - Make multiple restore jobs for multiple media types specifying
840 the proper storage type.
841 - Fix fast block rejection (stored/read_record.c:118). It passes a null
842 pointer (rec) to try_repositioning().
843 - Look at extracting Win data from BackupRead.
844 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
845 which would take precidence over the Catalog "JobRetention".
846 - Implement Label Format in Add and Label console commands.
847 - Possibly up network buffers to 65K. Put on variable.
848 - Put email tape request delays on one or more variables. User wants
849 to cancel the job after a certain time interval. Maximum Mount Wait?
850 - Job, Client, Device, Pool, or Volume?
851 Is it possible to make this a directive which is *optional* in multiple
852 resources, like Level? If so, I think I'd make it an optional directive
853 in Job, Client, and Pool, with precedence such that Job overrides Client
854 which in turn overrides Pool.
856 - New Storage specifications:
857 - Want to write to multiple storage devices simultaneously
858 - Want to write to multiple storage devices sequentially (in one job)
859 - Want to read/write simultaneously
860 - Key is MediaType -- it must match
862 Passed to SD as a sort of BSR record called Storage Specification
866 MediaType -> Next MediaType
868 Device -> Next Device
870 Allow multiple Storage specifications
878 Allow Multiple Pool specifications (note, Pool currently
880 Allow Multiple MediaType specifications in Dir conf
881 Allow Multiple Device specifications in Dir conf
882 Perhaps keep this in a single SSR
883 Tie a Volume to a specific device by using a MediaType that
884 is contained in only one device.
885 In SD allow Device to have Multiple MediaTypes
887 - Ideas from Jerry Scharf:
888 First let's point out some big pluses that bacula has for this
890 more importantly it's active. Thank you so much for that
891 even more important, it's not flaky
892 it has an open access catalog, opening many possibilities
893 it's pushing toward heterogeneous systems capability
895 Macintosh file client
896 macs are an interesting niche, but I fear a server is a rathole
897 working bare iron recovery for windows
898 the option for inc/diff backups not reset on fileset revision
899 a) use both change and inode update time against base time
900 b) do the full catalog check (expensive but accurate)
901 sizing guide (how much system is needed to back up N systems/files)
902 consultants on using bacula in building a disaster recovery system
904 or how to get at fancy things that one could do with bacula
905 logwatch code for bacula logs (or similar)
906 linux distro inclusion of bacula (brings good and bad, but necessary)
907 win2k/XP server capability (icky but you asked)
908 support for Oracle database ??
910 - Look at adding SQL server and Exchange support for Windows.
911 - Make dev->file and dev->block_num signed integers so that -1 can
912 be an invalid value which happens with BSR.
913 - Create VolAddr for disk files in place of VolFile and VolBlock. This
914 is needed to properly specify ranges.
915 - Add progress of files/bytes to SD and FD.
916 - Print warning message if FileId > 4 billion
917 - do a "messages" before the first prompt in Console
918 - Client does not show busy during Estimate command.
919 - Implement Console mtx commands.
920 - Implement a Mount Command and an Unmount Command where
921 the users could specify a system command to be performed
922 to do the mount, after which Bacula could attempt to
923 read the device. This is for Removeable media such as a CDROM.
924 - Most likely, this mount command would be invoked explicitly
925 by the user using the current Console "mount" and "unmount"
926 commands -- the Storage Daemon would do the right thing
927 depending on the exact nature of the device.
928 - As with tape drives, when Bacula wanted a new removable
929 disk mounted, it would unmount the old one, and send a message
930 to the user, who would then use "mount" as described above
931 once he had actually inserted the disk.
932 - Implement dump/print label to UA
933 - Spool to disk only when the tape is full, then when a tape is hung move
935 - bextract is sending everything to the log file ****FIXME****
936 - Allow multiple Storage specifications (or multiple names on
937 a single Storage specification) in the Job record. Thus a job
938 can be backed up to a number of storage devices.
939 - Implement some way for the File daemon to contact the Director
940 to start a job or pass its DHCP obtained IP number.
941 - Implement a query tape prompt/replace feature for a console
942 - Copy console @ code to gnome2-console
943 - Make AES the only encryption algorithm see
944 http://csrc.nist.gov/CryptoToolkit/aes/). It's
945 an officially adopted standard, has survived peer
946 review, and provides keys up to 256 bits.
947 - Take a careful look at SetACL http://setacl.sourceforge.net
948 - Make tree walk routines like cd, ls, ... more user friendly
949 by handling spaces better.
950 - Make sure that Bacula rechecks the tape after the 20 min wait.
951 - Set IO_NOWAIT on Bacula TCP/IP packets.
952 - Try doing a raw partition backup and restore by mounting a
955 Yes, it would allow to highly automatic the request for new tapes. If a
956 tape is empty, bacula reads the barcodes (native or simulated), and if
957 an unused tape is found, it runs the label command with all the
958 necessary parameters.
960 By the way can bacula automatically "move" an empty/purged volume say
961 in the "short" pool to the "long" pool if this pool runs out of volume
963 - What to do about "list files job=xxx".
964 - Get and test MySQL 4.0
965 - Look at how fuser works and /proc/PID/fd that is how Nic found the
966 file descriptor leak in Bacula.
967 - Implement WrapCounters in Counters.
968 - Add heartbeat from FD to SD if hb interval expires.
969 - Can we dynamically change FileSets?
970 - If pool specified to label command and Label Format is specified,
971 automatically generate the Volume name.
972 - Why can't SQL do the filename sort for restore?
973 - Add ExhautiveRestoreSearch
974 - Look at the possibility of loading only the necessary
975 data into the restore tree (i.e. do it one directory at a
976 time as the user walks through the tree).
977 - Possibly use the hash code if the user selects all for a restore command.
978 - Fix "restore all" to bypass building the tree.
979 - Prohibit backing up archive device (findlib/find_one.c:128)
980 - Implement Release Device in the Job resource to unmount a drive.
981 - Implement Acquire Device in the Job resource to mount a drive,
982 be sure this works with admin jobs so that the user can get
983 prompted to insert the correct tape. Possibly some way to say to
984 run the job but don't save the files.
985 - Make things like list where a file is saved case independent for
988 - Use autochanger to handle multiple devices.
989 - On Windows with very long path names, it may be impossible to create
990 a file (and thus restore it) because the total length is too long.
991 We must cd into the directory then create the file without the
993 - Implement a Recycle command
994 - Test a second language e.g. french.
995 - Start working on Base jobs.
996 - Implement UnsavedFiles DB record.
997 - From Phil Stracchino:
998 It would probably be a per-client option, and would be called
999 something like, say, "Automatically purge obsoleted jobs". What it
1000 would do is, when you successfully complete a Differential backup of a
1001 client, it would automatically purge all Incremental backups for that
1002 client that are rendered redundant by that Differential. Likewise,
1003 when a Full backup on a client completed, it would automatically purge
1004 all Differential and Incremental jobs obsoleted by that Full backup.
1005 This would let people minimize the number of tapes they're keeping on
1006 hand without having to master the art of retention times.
1007 - When doing a Backup send all attributes back to the Director, who
1008 would then figure out what files have been deleted.
1009 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1010 explicit permission to do so. It should also mark the tape in error
1011 if there is an error.
1012 - Cancel waiting for Client connect in SD if FD goes away.
1014 - Implement timeout in response() when it should come quickly.
1015 - Implement a Slot priority (loaded/not loaded).
1016 - Implement "vacation" Incremental only saves.
1017 - Implement create "FileSet"?
1018 - Add prefixlinks to where or not where absolute links to FD.
1019 - Issue message to mount a new tape before the rewind.
1020 - Simplified client job initiation for portables.
1021 - If SD cannot open a drive, make it periodically retry.
1022 - Add more of the config info to the tape label.
1024 - If tape is marked read-only, then try opening it read-only rather than
1025 failing, and remember that it cannot be written.
1026 - Refine SD waiting output:
1027 Device is being positioned
1028 > Device is being positioned for append
1029 > Device is being positioned to file x
1031 - Figure out some way to estimate output size and to avoid splitting
1032 a backup across two Volumes -- this could be useful for writing CDROMs
1033 where you really prefer not to have it split -- not serious.
1034 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1035 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1036 actual data on the Volume and compare it.
1037 - Implement Bacula plugins -- design API
1038 - Make bcopy read through bad tape records.
1039 - Program files (i.e. execute a program to read/write files).
1040 Pass read date of last backup, size of file last time.
1041 - Add Signature type to File DB record.
1042 - CD into subdirectory when open()ing files for backup to
1043 speed up things. Test with testfind().
1044 - Priority job to go to top of list.
1045 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1046 - Implement some way for the Console to dynamically create a job.
1047 - Solaris -I on tar for include list
1048 - Need a verbose mode in restore, perhaps to bsr.
1049 - bscan without -v is too quiet -- perhaps show jobs.
1050 - Add code to reject whole blocks if not wanted on restore.
1051 - Check if we can increase Bacula FD priorty in Win2000
1052 - Make sure the MaxVolFiles is fully implemented in SD
1053 - Check if both CatalogFiles and UseCatalog are set to SD.
1054 - Possibly add email to Watchdog if drive is unmounted too
1055 long and a job is waiting on the drive.
1056 - After unmount, if restore job started, ask to mount.
1057 - Add UA rc and history files.
1058 - put termcap (used by console) in ./configure and
1059 allow -with-termcap-dir.
1060 - Fix Autoprune for Volumes to respect need for full save.
1061 - Compare tape to Client files (attributes, or attributes and data)
1062 - Make all database Ids 64 bit.
1063 - Allow console commands to detach or run in background.
1064 - Fix status delay on storage daemon during rewind.
1065 - Add SD message variables to control operator wait time
1066 - Maximum Operator Wait
1067 - Minimum Message Interval
1068 - Maximum Message Interval
1069 - Send Operator message when cannot read tape label.
1070 - Verify level=Volume (scan only), level=Data (compare of data to file).
1071 Verify level=Catalog, level=InitCatalog
1073 - Add keyword search to show command in Console.
1074 - Events : tape has more than xxx bytes.
1075 - Complete code in Bacula Resources -- this will permit
1076 reading a new config file at any time.
1077 - Handle ctl-c in Console
1078 - Implement script driven addition of File daemon to config files.
1079 - Think about how to make Bacula work better with File (non-tape) archives.
1080 - Write Unix emulator for Windows.
1081 - Put memory utilization in Status output of each daemon
1082 if full status requested or if some level of debug on.
1083 - Make database type selectable by .conf files i.e. at runtime
1084 - Set flag for uname -a. Add to Volume label.
1085 - Restore files modified after date
1086 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1087 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1088 - Timout a job or terminate if link goes down, or reopen link and query.
1089 - Concept of precious tapes (cannot be reused).
1090 - Make bcopy copy with a single tape drive.
1091 - Permit changing ownership during restore.
1094 > My suggestion: Add a feature on the systray menu-icon menu to request
1095 > an immediate backup now. This would be useful for laptop users who may
1096 > not be on the network when the regular scheduled backup is run.
1098 > My wife's suggestion: Add a setting to the win32 client to allow it to
1099 > shut down the machine after backup is complete (after, of course,
1100 > displaying a "System will shut down in one minute, click here to cancel"
1101 > warning dialog). This would be useful for sites that want user
1102 > woorkstations to be shut down overnight to save power.
1105 - Autolabel should be specified by DIR instead of SD.
1107 - Add media capacity
1108 - AutoScan (check checksum of tape)
1109 - Format command = "format /dev/nst0"
1113 - Seek resolution (usually corresponds to buffer size)
1114 - EODErrorCode=ENOSPC or code
1115 - Partial Read error code
1116 - Partial write error code
1117 - Nonformatted read error
1118 - Nonformatted write error
1119 - WriteProtected error
1123 - IgnoreCloseErrors=yes
1133 - FD sends unsaved file list to Director at end of job (see
1135 - File daemon should build list of files skipped, and then
1136 at end of save retry and report any errors.
1137 - Write a Storage daemon that uses pipes and
1138 standard Unix programs to write to the tape.
1140 - Need something that monitors the JCR queue and
1141 times out jobs by asking the deamons where they are.
1142 - Enhance Jmsg code to permit buffering and saving to disk.
1143 - device driver = "xxxx" for drives.
1144 - Verify from Volume
1145 - Ensure that /dev/null works
1146 - Need report class for messages. Perhaps
1147 report resource where report=group of messages
1148 - enhance scan_attrib and rename scan_jobtype, and
1149 fill in code for "since" option
1150 - Director needs a time after which the report status is sent
1151 anyway -- or better yet, a retry time for the job.
1152 - Don't reschedule a job if previous incarnation is still running.
1153 - Some way to automatically backup everything is needed????
1154 - Need a structure for pending actions:
1156 - termination status (part of buffered msgs?)
1158 Read, Write, Clean, Delete
1159 - Login to Bacula; Bacula users with different permissions:
1160 owner, group, user, quotas
1161 - Store info on each file system type (probably in the job header on tape.
1162 This could be the output of df; or perhaps some sort of /etc/mtab record.

1167 Subject: RE: [Bacula-users] future large programming jobs
1168 Date: Thu, 26 Feb 2004 11:34:54 -0600
1170 I noticed the subject thread and thought I would offer the following
1171 merely as sources of ideas, i.e. something to think about, not even as
1172 strong as a request. In my former life (before retiring) I often
1173 dealt with backups and storage management issues/products as a
1174 developer and as a consultant. I am currently migrating my personal
1175 network from amanda to bacula specifically because of the ability to
1176 cross media boundaries during storing backups.
1177 Are you familiar with the commercial product called ADSM (I think IBM
1178 now sells it under the Tivoli label)? It has a couple of interesting
1179 ideas that may apply to the following topics.
1181 1. Migration: Consider that when you need to restore a system, there
1182 may be pressure to hurry. If all the information for a single client
1183 can eventually end up on the same media (and in chronological order),
1184 the restore is facillitated by not having to search past information
1185 from other clients. ADSM has the concept of "client affinity" that
1186 may be associated with it's storage pools. It seems to me that this
1187 concept (as an optional feature) might fit in your architecture for
1190 ADSM also has the concept of defining one or more storage pools as
1191 "copy pools" (almost mirrors, but only in the sense of contents).
1192 These pools provide the ability to have duplicte data stored both
1193 onsite and offsite. The copy process can be scheduled to be handled
1194 by their storage manager during periods when there is no backup
1195 activity. Again, the migration process might be a place to consider
1196 implementing something like this.
1199 > It strikes me that it would be very nice to be able to do things

1207 > mechanism described below would probably make it very easy.
1209 This is the goal. In the first step (before events), you simply
1211 the Migration to tape later.
1213 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1214 the database. Once a file (unique by path and metadata such as dates,
1215 size, ownership, etc.) is in a copy pool, no more copies are made. In
1216 other words, when you start ADSM, it begins like your concept of a
1217 base job. After that it is in the "incremental" mode. You can
1218 configure the number of "generations" of files to be retained, plus a
1219 retention date after which even old generations are purged. The
1220 database tracks the contents of media and projects the percentage of
1221 each volume that is valid. When the valid content of a volume drops
1222 below a configured percentage, the valid data are migrated to another
1223 volume and the old volume is marked as empty. Note, this requires
1224 ADSM to have an idea of the contents of a client, i.e. marking the
1225 database when an existing file was deleted, but this would solve your
1226 issue of restoring a client without restoring deleted files.
1228 This is pretty far from what bacula now does, but if you are going to
1229 rip things up for Base jobs,.....
1230 Also, the benefits of this are huge for very large shops, especially
1231 with media robots, but are a pain for shops with manual media
1235 > Base jobs sound pretty useful, but I'm not dying for them.
1237 Nobody is dying for them, but when you see what it does, you will die
1240 3. Restoring deleted files: Since I think my comments in (2) above
1241 have low probability of implementation, I'll also suggest that you
1242 could approach the issue of deleted files by a mechanism of having the
1243 fd report to the dir, a list of all files on the client for every
1244 backup job. The dir could note in the database entry for each file
1245 the date that the file was seen. Then if a restore as of date X takes
1246 place, only files that exist from before X until after X would be
1247 restored. Probably the major cost here is the extra date container in
1248 each row of the files table.
1250 Thanks for "listening". I hope some of this helps. If you want to
1251 contact me, please send me an email - I read some but not all of the
1252 mailing list traffic and might miss a reply there.
1254 Please accept my compliments for bacula. It is doing a great job for
1255 me!! I sympathize with you in the need to wrestle with excelence in
1256 execution vs. excelence in feature inclusion.
1261 ==============================
1264 - Design at hierarchial storage for Bacula. Migration and Clone.
1265 - Implement FSM (File System Modules).
1266 - Audit M_ error codes to ensure they are correct and consistent.
1267 - Add variable break characters to lex analyzer.
1268 Either a bit mask or a string of chars so that
1269 the caller can change the break characters.
1270 - Make a single T_BREAK to replace T_COMMA, etc.
1271 - Ensure that File daemon and Storage daemon can
1272 continue a save if the Director goes down (this
1273 is NOT currently the case). Must detect socket error,
1274 buffer messages for later.
1275 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1276 - Add ability to backup to two Storage devices (two SD sessions) at
1277 the same time -- e.g. onsite, offsite.
1278 - Add the ability to consolidate old backup sets (basically do a restore
1279 to tape and appropriately update the catalog). Compress Volume sets.
1280 Might need to spool via file is only one drive is available.
1281 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1282 someway to do so with every volume that has less than x% valid
1286 Migration: Move a backup from one Volume to another
1287 Clone: Copy a backup -- two Volumes
1289 Bacula Migration is based on Jobs (apparently Networker is file by file).

1300 ======================================================
1302 It is somewhat like a Full save becomes an incremental since
1303 the Base job (or jobs) plus other non-base files.
1305 - A Base backup is same as Full backup, just different type.
1306 - New BaseFiles table that contains:
1308 BaseJobId - Base JobId referenced for this FileId (needed ???)
1309 JobId - JobId currently running
1310 FileId - File not backed up, exists in Base Job
1311 FileIndex - FileIndex from Base Job.
1312 i.e. for each base file that exists but is not saved because
1313 it has not changed, the File daemon sends the JobId, BaseId,
1314 FileId, FileIndex back to the Director who creates the DB entry.
1315 - To initiate a Base save, the Director sends the FD
1316 the FileId, and full filename for each file in the Base.
1317 - When the FD finds a Base file, he requests the Director to
1318 send him the full File entry (stat packet plus MD5), or
1319 conversely, the FD sends it to the Director and the Director
1320 says yes or no. This can be quite rapid if the FileId is kept
1321 by the FD for each Base Filename.
1322 - It is probably better to have the comparison done by the FD
1323 despite the fact that the File entry must be sent across the
1325 - An alternative would be to send the FD the whole File entry
1326 from the start. The disadvantage is that it requires a lot of
1327 space. The advantage is that it requires less communications
1329 - The Job record must be updated to indicate that one or more
1331 - At end of Job, FD returns:
1332 1. Count of base files/bytes not written to tape (i.e. matches)
1333 2. Count of base file that were saved i.e. had changed.
1334 - No tape record would be written for a Base file that matches, in the
1335 same way that no tape record is written for Incremental jobs where
1336 the file is not saved because it is unchanged.
1337 - On a restore, all the Base file records must explicitly be
1338 found from the BaseFile tape. I.e. for each Full save that is marked
1339 to have one or more Base Jobs, search the BaseFile for all occurrences
1341 - An optimization might be to make the BaseFile have:
1347 This would avoid the need to explicitly fetch each File record for
1348 the Base job. The Base Job record will be fetched to get the
1349 VolSessionId and VolSessionTime.
1350 =========================================================
1353 ==========================================================
1355 For each Incremental job that is run, there may be files that
1356 were found but not saved because they were locked (this applies
1357 only to Windows). Such a system could send back to the Director
1358 a list of Unsaved files.
1360 - New UnSavedFiles table that contains:
1364 - Then in the next Incremental job, the list of Unsaved Files will be
1365 feed to the FD, who will ensure that they are explicitly chosen even
1366 if standard date/time check would not have selected them.

1411 There needs to be a table of drive # to devices somewhere - If there are
1412 multiple changers or drives there may not be a 1:1 correspondance between
1413 changer drive number and system device name - and depending on the way the
1414 drives are hooked up to scsi busses, they may not be linearly numbered
1415 from an offset point either.something like
1417 Autochanger drives = 2
1418 Autochanger drive 0 = /dev/nst1
1419 Autochanger drive 1 = /dev/nst2
1420 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1421 times, not just for multidrive changers. For a 1 drive changer, that's
1427 MTX's manpage (1.2.15):
1428 unload [<slotnum>] [ <drivenum> ]
1429 Unloads media from drive <drivenum> into slot
1430 <slotnum>. If <drivenum> is omitted, defaults to
1431 drive 0 (as do all commands). If <slotnum> is
1432 omitted, defaults to the slot that the drive was
1433 loaded from. Note that there's currently no way
1434 to say 'unload drive 1's media to the slot it
1435 came from', other than to explicitly use that
1436 slot number as the destination.AB

1474 Handling removable disks
1476 From: Karl Cunningham <karlc@keckec.com>
1478 My backups are only to hard disk these days, in removable bays. This is my
1479 idea of how a backup to hard disk would work more smoothly. Some of these
1480 things Bacula does already, but I mention them for completeness. If others
1481 have better ways to do this, I'd like to hear about it.
1483 1. Accommodate several disks, rotated similar to how tapes are. Identified
1484 by partition volume ID or perhaps by the name of a subdirectory.
1485 2. Abort & notify the admin if the wrong disk is in the bay.
1486 3. Write backups to different subdirectories for each machine to be backed
1488 4. Volumes (files) get created as needed in the proper subdirectory, one
1490 5. When a disk is recycled, remove or zero all old backup files. This is
1491 important as the disk being recycled may be close to full. This may be
1492 better done manually since the backup files for many machines may be
1493 scattered in many subdirectories.
1498 - Make sure that all do_prompt() calls in Dir check for
1499 -1 (error) and -2 (cancel) returns.
1500 - Fix foreach_jcr() to have free_jcr() inside next().
1501 jcr=jcr_walk_start();
1502 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1505 - A Volume taken from Scratch should take on the retention period
1507 - Correct doc for Maximum Changer Wait (and others) accepting only
1509 - Implement status that shows why a job is being held in reserve, or
1510 rather why none of the drives are suitable.
1511 - Implement a way to disable a drive (so you can use the second
1512 drive of an autochanger, and the first one will not be used or
1514 - Make sure Maximum Volumes is respected in Pools when adding
1515 Volumes (e.g. when pulling a Scratch volume).
1516 - Keep same dcr when switching device ...
1517 - Implement code that makes the Dir aware that a drive is an
1518 autochanger (so the user doesn't need to use the Autochanger = yes
1520 - Make catalog respect ACL.
1521 - Add recycle count to Media record.
1522 - Add initial write date to Media record.
1523 - Fix store_yesno to be store_bitmask.
