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 - Implement VolumeState as discussed with Arno.
28 - Document techniques for restoring large numbers of files.
29 - Document setting my.cnf to big file usage.
30 - Add example of proper index output to doc.

33 a block, and check if block was written by a different job
34 (i.e. multiple simultaneous jobs writing).
35 - JobStatus and Termination codes.
36 - Some users claim that they must do two prune commands to get a
37 Volume marked as purged.

51 Next Pool = <override>
54 There should be no need for a Level (migration is always Full, since you
55 don't calculate differential/incremental differences for migration),
56 Storage should be determined by the volume types in the pool, and Client
57 is really a selection issue. Migration should always occur to the
58 NextPool defined in the pool definition. If no nextpool is defined, the
59 job should end with a reason of "no place to go". If Next Pool statement
60 is present, we override the check in the pool definition and use the

66 Client -- Migrate data from selected client only. Migration Selection
67 Pattern regexp provides pattern to select client names, eg ^FS00* makes
68 all client names starting with FS00 eligible for migration.
70 Jobname -- Migration all jobs matching name. Migration Selection Pattern
71 regexp provides pattern to select jobnames existing in pool.
73 Volume -- Migrate all data on specified volumes. Migration Selection
74 Pattern regexp provides selection criteria for volumes to be migrated.
75 Volumes must exist in pool to be eligible for migration.
79 LowestUtil -- Identify the volume in the pool with the least data on it
80 and empty it. No Migration Selection Pattern required.
82 OldestVol -- Identify the LRU volume with data written, and empty it. No
83 Migration Selection Pattern required.
85 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
86 (starting with most full volumes) until pool occupancy drops below
87 <lowmig>. Pool highmig and lowmig values are in pool definition, no
88 Migration Selection Pattern required.
92 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
93 Migration Selection Pattern contains SQL query to execute; should return
94 a list of 1 or more jobuids to migrate.
96 PoolResidence -- Migrate data sitting in pool for longer than

267 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and

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

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

503 - Win32 systems with FAT32 can be much slower than NTFS for
504 more than 1000 files per directory.

515 === From Carsten Menke <bootsy52@gmx.net>
517 Following is a list of what I think in the situations where I'm faced with,
518 could be a usefull enhancement to bacula, which I'm certain other users will
519 benefit from as well.
521 1. NextJob/NextJobs Directive within a Job Resource in the form of
522 NextJobs = job1,job2.
525 I currently solved the problem with running multiple jobs each after each
526 by setting the Max Wait Time for a job to 8 hours, and give
527 the jobs different Priorities. However, there scenarios where
528 1 Job is directly depending on another job, so if the former job fails,
529 the job after it needn't to be run
530 while maybe other jobs should run despite of that
533 A Backup Job and a Verify job, if the backup job fails there is no need to run
534 the verify job, as the backup job already failed. However, one may like
535 to backup the Catalog to disk despite of that the main backup job failed.
538 I see that this is related to the Event Handlers which are on the ToDo
539 list, also it is maybe a good idea to check for the return value and
540 execute different actions based on the return value
543 3. offline capability to bconsole
546 Currently I use a script which I execute within the last Job via the
547 RunAfterJob Directive, to release and eject the tape.
548 So I have to call bconsole "release=Storage-Name" and afterwards
549 mt -f /dev/nst0 eject to get the tape out.
551 If I have multiple Storage Devices, than these may not be /dev/nst0 and
552 I have to modify the script or call it with parameters etc.
553 This would actually not be needed, as everything is already defined
554 in bacula-sd.conf and if I can invoke bconsole with the
555 storage name via $1 in the script than I'm done and information is
558 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
562 For the reason mentioned in 3. to have the ability to call a
563 script with /scripts/foobar %s and in the script use $1
564 to pass the Storage Name to bconsole
566 5. Setting Volume State within a Job Resource
569 Instead of using "Maximum Volume Jobs" in the Pool Resource,
570 I would have the possibilty to define
571 in a Job Resource that after this certain job is run, the Volume State
572 should be set to "Volume State = Used", this give more flexibility (IMHO).
574 6. Localization of Bacula Messages
577 Unfortunatley many,many people I work with don't speak english very well.
578 So if at least the Reporting messages would be localized then they
579 would understand that they have to change the tape,etc. etc.
581 I volunteer to do the german translations, and if I can convince my wife also
582 french and Morre (western african language).
584 7. OK, this is evil, probably bound to security risks and maybe not possible
585 due to the design of bacula.
587 Implementation of Backtics ( `command` ) for shell comand execution to
588 the "Label Format" Directive.
592 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
593 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
594 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
595 the localized name for the day of the week appended to the
596 format string. Then I have the tape labeled automatically with weekday
597 name in the correct language.
599 - Yes, that is surely the case. I probably should turn those into Warning
600 errors. In addition, you just made me think that it might not be bad to
601 add an option to check the file size after backing up the file and
602 report if it changes. This would be done as an option because it would
605 Kern, good idea. If you do do that, mention in the output: file
606 shrunk, or file expanded, just to make it obvious to the user
607 (without having to the refer to file size), just how the file size
610 Would this option be for all file, or just one file? Or a fileset?
611 - Make output from status use html table tags for nicely
612 presenting in a browser.
613 - Can one write tapes faster with 8192 byte block sizes?
614 - Document security problems with the same password for everyone in
615 rpm and Win32 releases.
616 - Browse generations of files.
617 - I've seen an error when my catalog's File table fills up. I
618 then have to recreate the File table with a larger maximum row
619 size. Relevant information is at
620 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
621 "Installing and Configuring MySQL" chapter should talk a bit
622 about this potential problem, and recommend a solution.
623 - For Solaris must use POSIX awk.
624 - Want speed of writing to tape while despooling.
625 - Supported autochanger:
633 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
634 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
635 - Add regex from http://www.pcre.org to Bacula for Win32.
636 - Use only shell tools no make in CDROM package.
637 - Include within include does it work?
638 - Implement a Pool of type Cleaning?
639 - Implement VolReadTime and VolWriteTime in SD
640 - Modify Backing up Your Database to include a bootstrap file.
641 - Think about making certain database errors fatal.
642 - Look at correcting the time jump in the scheduler for daylight
643 savings time changes.
644 - Add a "real" timer to network connections.
645 - Promote to Full = Time period
646 - Check dates entered by user for correctness (month/day/... ranges)
647 - Compress restore Volume listing by date and first file.
648 - Look at patches/bacula_db.b2z postgresql that loops during restore.
650 - Perhaps add read/write programs and/or plugins to FileSets.
651 - How to handle backing up portables ...
652 - Add some sort of guaranteed Interval for upgrading jobs.
653 - Can we write the state file after every job terminates? On Win32
654 the system crashes and the state file is not updated.
657 Documentation to do: (any release a little bit at a time)
658 - Doc to do unmount before removing magazine.
659 - Alternative to static linking "ldd prog" save all binaries listed,
660 restore them and point LD_LIBRARY_PATH to them.
661 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
662 - Document query file format.
663 - Add more documentation for bsr files.
664 - Document problems with Verify and pruning.
665 - Document how to use multiple databases.
666 - VXA drives have a "cleaning required"
667 indicator, but Exabyte recommends preventive cleaning after every 75
670 In this context, it should be noted that Exabyte has a command-line
671 vxatool utility available for free download. (The current version is
672 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
673 test the drive, unload tapes, change drive settings, flash new firmware,
675 Of particular interest in this context is that vxatool <device> -i will
676 report, among other details, the time since last cleaning in tape motion
677 minutes. This information can be retrieved (and settings changed, for
678 that matter) through the generic-SCSI device even when Bacula has the
679 regular tape device locked. (Needless to say, I don't recommend
680 changing tape settings while a job is running.)
681 - Lookup HP cleaning recommendations.
682 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
683 - Document doing table repair
686 ===================================
687 - Add macro expansions in JobDefs.
688 Run Before Job = "SomeFile %{Level} %{Client}"
689 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
690 - Use non-blocking network I/O but if no data is available, use
692 - Use gather write() for network I/O.
693 - Autorestart on crash.
694 - Add bandwidth limiting.
695 - Add acks every once and a while from the SD to keep
696 the line from timing out.
697 - When an error in input occurs and conio beeps, you can back
698 up through the prompt.
699 - Detect fixed tape block mode during positioning by looking at
700 block numbers in btape "test". Possibly adjust in Bacula.
701 - Fix list volumes to output volume retention in some other
702 units, perhaps via a directive.
703 - If opening a tape in read/write mode fails attempt to open
704 it in read-only mode, and mark the tape for read only.
705 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
706 with multiple priorities.
707 - If you use restore replace=never, the directory attributes for
708 non-existent directories will not be restored properly.
710 - see lzma401.zip in others directory for new compression
712 - Minimal autochanger handling in Bacula and in btape.
713 - Look into how tar does not save sockets and the possiblity of
714 not saving them in Bacula (Martin Simmons reported this).
715 - Fix restore jobs so that multiple jobs can run if they
716 are not using the same tape(s).
717 - Allow the user to select JobType for manual pruning/purging.
718 - bscan does not put first of two volumes back with all info in
720 - Implement the FreeBSD nodump flag in chflags.
721 - Figure out how to make named console messages go only to that
722 console and to the non-restricted console (new console class?).
723 - Make restricted console prompt for password if *ask* is set or
724 perhaps if password is undefined.
725 - Implement "from ISO-date/time every x hours/days/weeks/months" in
728 ==== from Marc Schoechlin
729 - the help-command should be more verbose
730 (it should explain the paramters of the different
732 -> its time-comsuming to consult the manual anytime
733 you need a special parameter
734 -> maybe its more easy to maintain this, if the
735 descriptions of that commands are outsourced to
737 - the cd-command should allow complete paths
738 i.e. cd /foo/bar/foo/bar
739 -> if a customer mails me the path to a certain file,
740 its faster to enter the specified directory
741 - if the password is not configured in bconsole.conf
742 you should be asked for it.
743 -> sometimes you like to do restore on a customer-machine
744 which shouldnt know the password for bacula.
745 -> adding the password to the file favours admins
746 to forget to remove the password after usage
748 the protection of that file is less important
749 - long-listed-output of commands should be scrollable
750 like the unix more/less-command does
751 -> if someone runs 200 and more machines, the lists could
752 be a little long and complex
753 - command-output should be shown column by column
754 to reduce scrolling and to increase clarity
756 - lsmark should list the selected files with full
758 - wildcards for selecting and file and directories would be nice
759 - any actions should be interuptable with STRG+C
760 - command-expansion would be pretty cool
762 - When the replace Never option is set, new directory permissions
763 are not restored. See bug 213. To fix this requires creating a
764 list of newly restored directories so that those directory
765 permissions *can* be restored.
766 - Compaction of Disk space by "migrating" Volumes that have pruned
767 Jobs (what criteria? size, #jobs, time).
768 - Add prune all command
769 - Document fact that purge can destroy a part of a restore by purging
770 one volume while others remain valid -- perhaps mark Jobs.
771 - Add multiple-media-types.txt
772 - look at mxt-changer.html
773 - Make ? do a help command (no return needed).
774 - Implement restore directory.
775 - Document streams and how to implement them.
776 - Try not to re-backup a file if a new hard link is added.
777 - Add feature to backup hard links only, but not the data.
778 - Fix stream handling to be simpler.
779 - Add Priority and Bootstrap to Run a Job.
780 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
782 - Remove View FileSet button from Run a Job dialog.
783 - Handle prompt for restore job at end of Restore command.
784 - Add display of total selected files to Restore window.
785 - Add tree pane to left of window.
786 - Add progress meter.
787 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
788 - Document writing to a CD/DVD with Bacula.
789 - Add a "base" package to the window installer for pthreadsVCE.dll
790 which is needed by all packages.
791 - Add message to user to check for fixed block size when the forward
792 space test fails in btape.
793 - When unmarking a directory check if all files below are unmarked and
794 then remove the + flag -- in the restore tree.
795 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
796 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
797 - Revisit the question of multiple Volumes (disk) on a single device.
798 - Add a block copy option to bcopy.
799 - Investigate adding Mac Resource Forks.
800 - Finish work on Gnome restore GUI.
801 - Fix "llist jobid=xx" where no fileset or client exists.
802 - For each job type (Admin, Restore, ...) require only the really necessary
803 fields.- Pass Director resource name as an option to the Console.
804 - Add a "batch" mode to the Console (no unsolicited queries, ...).
805 - Add a .list all files in the restore tree (probably also a list all files)
806 Do both a long and short form.
807 - Allow browsing the catalog to see all versions of a file (with
808 stat data on each file).
809 - Restore attributes of directory if replace=never set but directory
811 - Use SHA1 on authentication if possible.
812 - See comtest-xxx.zip for Windows code to talk to USB.
813 - Add John's appended files:
814 Appended = { /files/server/logs/http/*log }
815 and such files would be treated as follows.On a FULL backup, they would
816 be backed up like any other file.On an INCREMENTAL backup, where a
817 previous INCREMENTAL or FULL was already in thecatalogue and the length
818 of the file wasgreater than the length of the last backup, only thedata
819 added since the last backup will be dumped.On an INCREMENTAL backup, if
820 the length of the file is less than thelength of the file with the same
821 name last backed up, the completefile is dumped.On Windows systems, with
822 creation date of files, we can be evensmarter about this and not count
823 entirely upon the length.On a restore, the full and all incrementals
824 since it will beapplied in sequence to restore the file.
825 - Check new HAVE_WIN32 open bits.
826 - Check if the tape has moved before writing.
827 - Handling removable disks -- see below:
828 - Keep track of tape use time, and report when cleaning is necessary.
829 - Add FromClient and ToClient keywords on restore command (or
830 BackupClient RestoreClient).
831 - Implement a JobSet, which groups any number of jobs. If the
832 JobSet is started, all the jobs are started together.
833 Allow Pool, Level, and Schedule overrides.
834 - Enhance cancel to timeout BSOCK packets after a specific delay.
835 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
836 ua_status.!!! Thanks to Alan Brown for this tip.
837 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
838 correctly for multiple simultaneous jobs.
839 - Correct code so that FileSet MD5 is calculated for < and | filename
841 - Implement the Media record flag that indicates that the Volume does disk
843 - Implement VolAddr, which is used when Volume is addressed like a disk,
844 and form it from VolFile and VolBlock.
845 - Make multiple restore jobs for multiple media types specifying
846 the proper storage type.
847 - Fix fast block rejection (stored/read_record.c:118). It passes a null
848 pointer (rec) to try_repositioning().
849 - Look at extracting Win data from BackupRead.
850 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
851 which would take precidence over the Catalog "JobRetention".
852 - Implement Label Format in Add and Label console commands.
853 - Possibly up network buffers to 65K. Put on variable.
854 - Put email tape request delays on one or more variables. User wants
855 to cancel the job after a certain time interval. Maximum Mount Wait?
856 - Job, Client, Device, Pool, or Volume?
857 Is it possible to make this a directive which is *optional* in multiple
858 resources, like Level? If so, I think I'd make it an optional directive
859 in Job, Client, and Pool, with precedence such that Job overrides Client
860 which in turn overrides Pool.
862 - New Storage specifications:
863 - Want to write to multiple storage devices simultaneously
864 - Want to write to multiple storage devices sequentially (in one job)
865 - Want to read/write simultaneously
866 - Key is MediaType -- it must match
868 Passed to SD as a sort of BSR record called Storage Specification
872 MediaType -> Next MediaType
874 Device -> Next Device
876 Allow multiple Storage specifications
884 Allow Multiple Pool specifications (note, Pool currently
886 Allow Multiple MediaType specifications in Dir conf
887 Allow Multiple Device specifications in Dir conf
888 Perhaps keep this in a single SSR
889 Tie a Volume to a specific device by using a MediaType that
890 is contained in only one device.
891 In SD allow Device to have Multiple MediaTypes
893 - Ideas from Jerry Scharf:
894 First let's point out some big pluses that bacula has for this
896 more importantly it's active. Thank you so much for that
897 even more important, it's not flaky
898 it has an open access catalog, opening many possibilities
899 it's pushing toward heterogeneous systems capability
901 Macintosh file client
902 macs are an interesting niche, but I fear a server is a rathole
903 working bare iron recovery for windows
904 the option for inc/diff backups not reset on fileset revision
905 a) use both change and inode update time against base time
906 b) do the full catalog check (expensive but accurate)
907 sizing guide (how much system is needed to back up N systems/files)
908 consultants on using bacula in building a disaster recovery system
910 or how to get at fancy things that one could do with bacula
911 logwatch code for bacula logs (or similar)
912 linux distro inclusion of bacula (brings good and bad, but necessary)
913 win2k/XP server capability (icky but you asked)
914 support for Oracle database ??
916 - Look at adding SQL server and Exchange support for Windows.
917 - Make dev->file and dev->block_num signed integers so that -1 can
918 be an invalid value which happens with BSR.
919 - Create VolAddr for disk files in place of VolFile and VolBlock. This
920 is needed to properly specify ranges.
921 - Add progress of files/bytes to SD and FD.
922 - Print warning message if FileId > 4 billion
923 - do a "messages" before the first prompt in Console
924 - Client does not show busy during Estimate command.
925 - Implement Console mtx commands.
926 - Implement a Mount Command and an Unmount Command where
927 the users could specify a system command to be performed
928 to do the mount, after which Bacula could attempt to
929 read the device. This is for Removeable media such as a CDROM.
930 - Most likely, this mount command would be invoked explicitly
931 by the user using the current Console "mount" and "unmount"
932 commands -- the Storage Daemon would do the right thing
933 depending on the exact nature of the device.
934 - As with tape drives, when Bacula wanted a new removable
935 disk mounted, it would unmount the old one, and send a message
936 to the user, who would then use "mount" as described above
937 once he had actually inserted the disk.
938 - Implement dump/print label to UA
939 - Spool to disk only when the tape is full, then when a tape is hung move
941 - bextract is sending everything to the log file ****FIXME****
942 - Allow multiple Storage specifications (or multiple names on
943 a single Storage specification) in the Job record. Thus a job
944 can be backed up to a number of storage devices.
945 - Implement some way for the File daemon to contact the Director
946 to start a job or pass its DHCP obtained IP number.
947 - Implement a query tape prompt/replace feature for a console
948 - Copy console @ code to gnome2-console
949 - Make AES the only encryption algorithm see
950 http://csrc.nist.gov/CryptoToolkit/aes/). It's
951 an officially adopted standard, has survived peer
952 review, and provides keys up to 256 bits.
953 - Take a careful look at SetACL http://setacl.sourceforge.net
954 - Make tree walk routines like cd, ls, ... more user friendly
955 by handling spaces better.
956 - Make sure that Bacula rechecks the tape after the 20 min wait.
957 - Set IO_NOWAIT on Bacula TCP/IP packets.
958 - Try doing a raw partition backup and restore by mounting a
961 Yes, it would allow to highly automatic the request for new tapes. If a
962 tape is empty, bacula reads the barcodes (native or simulated), and if
963 an unused tape is found, it runs the label command with all the
964 necessary parameters.
966 By the way can bacula automatically "move" an empty/purged volume say
967 in the "short" pool to the "long" pool if this pool runs out of volume
969 - What to do about "list files job=xxx".
970 - Get and test MySQL 4.0
971 - Look at how fuser works and /proc/PID/fd that is how Nic found the
972 file descriptor leak in Bacula.
973 - Implement WrapCounters in Counters.
974 - Add heartbeat from FD to SD if hb interval expires.
975 - Can we dynamically change FileSets?
976 - If pool specified to label command and Label Format is specified,
977 automatically generate the Volume name.
978 - Why can't SQL do the filename sort for restore?
979 - Add ExhautiveRestoreSearch
980 - Look at the possibility of loading only the necessary
981 data into the restore tree (i.e. do it one directory at a
982 time as the user walks through the tree).
983 - Possibly use the hash code if the user selects all for a restore command.
984 - Fix "restore all" to bypass building the tree.
985 - Prohibit backing up archive device (findlib/find_one.c:128)
986 - Implement Release Device in the Job resource to unmount a drive.
987 - Implement Acquire Device in the Job resource to mount a drive,
988 be sure this works with admin jobs so that the user can get
989 prompted to insert the correct tape. Possibly some way to say to
990 run the job but don't save the files.
991 - Make things like list where a file is saved case independent for
994 - Use autochanger to handle multiple devices.
995 - On Windows with very long path names, it may be impossible to create
996 a file (and thus restore it) because the total length is too long.
997 We must cd into the directory then create the file without the
999 - Implement a Recycle command
1000 - Test a second language e.g. french.
1001 - Start working on Base jobs.
1002 - Implement UnsavedFiles DB record.
1003 - From Phil Stracchino:
1004 It would probably be a per-client option, and would be called
1005 something like, say, "Automatically purge obsoleted jobs". What it
1006 would do is, when you successfully complete a Differential backup of a
1007 client, it would automatically purge all Incremental backups for that
1008 client that are rendered redundant by that Differential. Likewise,
1009 when a Full backup on a client completed, it would automatically purge
1010 all Differential and Incremental jobs obsoleted by that Full backup.
1011 This would let people minimize the number of tapes they're keeping on
1012 hand without having to master the art of retention times.
1013 - When doing a Backup send all attributes back to the Director, who
1014 would then figure out what files have been deleted.
1015 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1016 explicit permission to do so. It should also mark the tape in error
1017 if there is an error.
1018 - Cancel waiting for Client connect in SD if FD goes away.
1020 - Implement timeout in response() when it should come quickly.
1021 - Implement a Slot priority (loaded/not loaded).
1022 - Implement "vacation" Incremental only saves.
1023 - Implement create "FileSet"?
1024 - Add prefixlinks to where or not where absolute links to FD.
1025 - Issue message to mount a new tape before the rewind.
1026 - Simplified client job initiation for portables.
1027 - If SD cannot open a drive, make it periodically retry.
1028 - Add more of the config info to the tape label.
1030 - If tape is marked read-only, then try opening it read-only rather than
1031 failing, and remember that it cannot be written.
1032 - Refine SD waiting output:
1033 Device is being positioned
1034 > Device is being positioned for append
1035 > Device is being positioned to file x
1037 - Figure out some way to estimate output size and to avoid splitting
1038 a backup across two Volumes -- this could be useful for writing CDROMs
1039 where you really prefer not to have it split -- not serious.
1040 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1041 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1042 actual data on the Volume and compare it.
1043 - Implement Bacula plugins -- design API
1044 - Make bcopy read through bad tape records.
1045 - Program files (i.e. execute a program to read/write files).
1046 Pass read date of last backup, size of file last time.
1047 - Add Signature type to File DB record.
1048 - CD into subdirectory when open()ing files for backup to
1049 speed up things. Test with testfind().
1050 - Priority job to go to top of list.
1051 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1052 - Implement some way for the Console to dynamically create a job.
1053 - Solaris -I on tar for include list
1054 - Need a verbose mode in restore, perhaps to bsr.
1055 - bscan without -v is too quiet -- perhaps show jobs.
1056 - Add code to reject whole blocks if not wanted on restore.
1057 - Check if we can increase Bacula FD priorty in Win2000
1058 - Make sure the MaxVolFiles is fully implemented in SD
1059 - Check if both CatalogFiles and UseCatalog are set to SD.
1060 - Possibly add email to Watchdog if drive is unmounted too
1061 long and a job is waiting on the drive.
1062 - After unmount, if restore job started, ask to mount.
1063 - Add UA rc and history files.
1064 - put termcap (used by console) in ./configure and
1065 allow -with-termcap-dir.
1066 - Fix Autoprune for Volumes to respect need for full save.
1067 - Compare tape to Client files (attributes, or attributes and data)
1068 - Make all database Ids 64 bit.
1069 - Allow console commands to detach or run in background.
1070 - Fix status delay on storage daemon during rewind.
1071 - Add SD message variables to control operator wait time
1072 - Maximum Operator Wait
1073 - Minimum Message Interval
1074 - Maximum Message Interval
1075 - Send Operator message when cannot read tape label.
1076 - Verify level=Volume (scan only), level=Data (compare of data to file).
1077 Verify level=Catalog, level=InitCatalog
1079 - Add keyword search to show command in Console.
1080 - Events : tape has more than xxx bytes.
1081 - Complete code in Bacula Resources -- this will permit
1082 reading a new config file at any time.
1083 - Handle ctl-c in Console
1084 - Implement script driven addition of File daemon to config files.
1085 - Think about how to make Bacula work better with File (non-tape) archives.
1086 - Write Unix emulator for Windows.
1087 - Put memory utilization in Status output of each daemon
1088 if full status requested or if some level of debug on.
1089 - Make database type selectable by .conf files i.e. at runtime
1090 - Set flag for uname -a. Add to Volume label.
1091 - Restore files modified after date
1092 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1093 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1094 - Timout a job or terminate if link goes down, or reopen link and query.
1095 - Concept of precious tapes (cannot be reused).
1096 - Make bcopy copy with a single tape drive.
1097 - Permit changing ownership during restore.
1100 > My suggestion: Add a feature on the systray menu-icon menu to request
1101 > an immediate backup now. This would be useful for laptop users who may
1102 > not be on the network when the regular scheduled backup is run.

1111 - Autolabel should be specified by DIR instead of SD.
1113 - Add media capacity
1114 - AutoScan (check checksum of tape)
1115 - Format command = "format /dev/nst0"
1119 - Seek resolution (usually corresponds to buffer size)
1120 - EODErrorCode=ENOSPC or code
1121 - Partial Read error code
1122 - Partial write error code
1123 - Nonformatted read error
1124 - Nonformatted write error
1125 - WriteProtected error
1129 - IgnoreCloseErrors=yes
1139 - FD sends unsaved file list to Director at end of job (see
1141 - File daemon should build list of files skipped, and then
1142 at end of save retry and report any errors.
1143 - Write a Storage daemon that uses pipes and
1144 standard Unix programs to write to the tape.
1146 - Need something that monitors the JCR queue and
1147 times out jobs by asking the deamons where they are.
1148 - Enhance Jmsg code to permit buffering and saving to disk.
1149 - device driver = "xxxx" for drives.
1150 - Verify from Volume
1151 - Ensure that /dev/null works
1152 - Need report class for messages. Perhaps
1153 report resource where report=group of messages
1154 - enhance scan_attrib and rename scan_jobtype, and
1155 fill in code for "since" option
1156 - Director needs a time after which the report status is sent
1157 anyway -- or better yet, a retry time for the job.
1158 - Don't reschedule a job if previous incarnation is still running.
1159 - Some way to automatically backup everything is needed????
1160 - Need a structure for pending actions:
1162 - termination status (part of buffered msgs?)
1164 Read, Write, Clean, Delete
1165 - Login to Bacula; Bacula users with different permissions:
1166 owner, group, user, quotas
1167 - Store info on each file system type (probably in the job header on tape.
1168 This could be the output of df; or perhaps some sort of /etc/mtab record.

1173 Subject: RE: [Bacula-users] future large programming jobs
1174 Date: Thu, 26 Feb 2004 11:34:54 -0600
1176 I noticed the subject thread and thought I would offer the following
1177 merely as sources of ideas, i.e. something to think about, not even as
1178 strong as a request. In my former life (before retiring) I often
1179 dealt with backups and storage management issues/products as a
1180 developer and as a consultant. I am currently migrating my personal
1181 network from amanda to bacula specifically because of the ability to
1182 cross media boundaries during storing backups.
1183 Are you familiar with the commercial product called ADSM (I think IBM
1184 now sells it under the Tivoli label)? It has a couple of interesting
1185 ideas that may apply to the following topics.
1187 1. Migration: Consider that when you need to restore a system, there
1188 may be pressure to hurry. If all the information for a single client
1189 can eventually end up on the same media (and in chronological order),
1190 the restore is facillitated by not having to search past information
1191 from other clients. ADSM has the concept of "client affinity" that
1192 may be associated with it's storage pools. It seems to me that this
1193 concept (as an optional feature) might fit in your architecture for
1196 ADSM also has the concept of defining one or more storage pools as
1197 "copy pools" (almost mirrors, but only in the sense of contents).
1198 These pools provide the ability to have duplicte data stored both
1199 onsite and offsite. The copy process can be scheduled to be handled
1200 by their storage manager during periods when there is no backup
1201 activity. Again, the migration process might be a place to consider
1202 implementing something like this.
1205 > It strikes me that it would be very nice to be able to do things
1207 > have the Job(s) backing up the machines run, and once they have all

1213 > mechanism described below would probably make it very easy.
1215 This is the goal. In the first step (before events), you simply
1217 the Migration to tape later.
1219 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1220 the database. Once a file (unique by path and metadata such as dates,
1221 size, ownership, etc.) is in a copy pool, no more copies are made. In
1222 other words, when you start ADSM, it begins like your concept of a
1223 base job. After that it is in the "incremental" mode. You can
1224 configure the number of "generations" of files to be retained, plus a
1225 retention date after which even old generations are purged. The
1226 database tracks the contents of media and projects the percentage of
1227 each volume that is valid. When the valid content of a volume drops
1228 below a configured percentage, the valid data are migrated to another
1229 volume and the old volume is marked as empty. Note, this requires
1230 ADSM to have an idea of the contents of a client, i.e. marking the
1231 database when an existing file was deleted, but this would solve your
1232 issue of restoring a client without restoring deleted files.
1234 This is pretty far from what bacula now does, but if you are going to
1235 rip things up for Base jobs,.....
1236 Also, the benefits of this are huge for very large shops, especially
1237 with media robots, but are a pain for shops with manual media
1241 > Base jobs sound pretty useful, but I'm not dying for them.
1243 Nobody is dying for them, but when you see what it does, you will die
1246 3. Restoring deleted files: Since I think my comments in (2) above
1247 have low probability of implementation, I'll also suggest that you
1248 could approach the issue of deleted files by a mechanism of having the
1249 fd report to the dir, a list of all files on the client for every
1250 backup job. The dir could note in the database entry for each file
1251 the date that the file was seen. Then if a restore as of date X takes
1252 place, only files that exist from before X until after X would be
1253 restored. Probably the major cost here is the extra date container in
1254 each row of the files table.
1256 Thanks for "listening". I hope some of this helps. If you want to
1257 contact me, please send me an email - I read some but not all of the
1258 mailing list traffic and might miss a reply there.
1260 Please accept my compliments for bacula. It is doing a great job for
1261 me!! I sympathize with you in the need to wrestle with excelence in
1262 execution vs. excelence in feature inclusion.
1267 ==============================
1270 - Design at hierarchial storage for Bacula. Migration and Clone.
1271 - Implement FSM (File System Modules).
1272 - Audit M_ error codes to ensure they are correct and consistent.
1273 - Add variable break characters to lex analyzer.
1274 Either a bit mask or a string of chars so that
1275 the caller can change the break characters.
1276 - Make a single T_BREAK to replace T_COMMA, etc.
1277 - Ensure that File daemon and Storage daemon can
1278 continue a save if the Director goes down (this
1279 is NOT currently the case). Must detect socket error,
1280 buffer messages for later.
1281 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1282 - Add ability to backup to two Storage devices (two SD sessions) at
1283 the same time -- e.g. onsite, offsite.
1284 - Add the ability to consolidate old backup sets (basically do a restore
1285 to tape and appropriately update the catalog). Compress Volume sets.
1286 Might need to spool via file is only one drive is available.
1287 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1288 someway to do so with every volume that has less than x% valid
1292 Migration: Move a backup from one Volume to another
1293 Clone: Copy a backup -- two Volumes
1295 Bacula Migration is based on Jobs (apparently Networker is file by file).

1301 Highwater mark (keep total size)
1306 ======================================================
1308 It is somewhat like a Full save becomes an incremental since
1309 the Base job (or jobs) plus other non-base files.
1311 - A Base backup is same as Full backup, just different type.
1312 - New BaseFiles table that contains:
1314 BaseJobId - Base JobId referenced for this FileId (needed ???)
1315 JobId - JobId currently running
1316 FileId - File not backed up, exists in Base Job
1317 FileIndex - FileIndex from Base Job.
1318 i.e. for each base file that exists but is not saved because
1319 it has not changed, the File daemon sends the JobId, BaseId,
1320 FileId, FileIndex back to the Director who creates the DB entry.
1321 - To initiate a Base save, the Director sends the FD
1322 the FileId, and full filename for each file in the Base.
1323 - When the FD finds a Base file, he requests the Director to
1324 send him the full File entry (stat packet plus MD5), or
1325 conversely, the FD sends it to the Director and the Director
1326 says yes or no. This can be quite rapid if the FileId is kept
1327 by the FD for each Base Filename.
1328 - It is probably better to have the comparison done by the FD
1329 despite the fact that the File entry must be sent across the
1331 - An alternative would be to send the FD the whole File entry
1332 from the start. The disadvantage is that it requires a lot of
1333 space. The advantage is that it requires less communications
1335 - The Job record must be updated to indicate that one or more
1337 - At end of Job, FD returns:
1338 1. Count of base files/bytes not written to tape (i.e. matches)
1339 2. Count of base file that were saved i.e. had changed.
1340 - No tape record would be written for a Base file that matches, in the
1341 same way that no tape record is written for Incremental jobs where
1342 the file is not saved because it is unchanged.
1343 - On a restore, all the Base file records must explicitly be
1344 found from the BaseFile tape. I.e. for each Full save that is marked
1345 to have one or more Base Jobs, search the BaseFile for all occurrences
1347 - An optimization might be to make the BaseFile have:
1353 This would avoid the need to explicitly fetch each File record for
1354 the Base job. The Base Job record will be fetched to get the
1355 VolSessionId and VolSessionTime.
1356 =========================================================
1359 ==========================================================
1361 For each Incremental job that is run, there may be files that
1362 were found but not saved because they were locked (this applies
1363 only to Windows). Such a system could send back to the Director
1364 a list of Unsaved files.
1366 - New UnSavedFiles table that contains:
1370 - Then in the next Incremental job, the list of Unsaved Files will be
1371 feed to the FD, who will ensure that they are explicitly chosen even
1372 if standard date/time check would not have selected them.

1414 (just to verify it remembers where it came from, however it can be

1417 There needs to be a table of drive # to devices somewhere - If there are
1418 multiple changers or drives there may not be a 1:1 correspondance between
1419 changer drive number and system device name - and depending on the way the
1420 drives are hooked up to scsi busses, they may not be linearly numbered
1421 from an offset point either.something like
1423 Autochanger drives = 2
1424 Autochanger drive 0 = /dev/nst1
1425 Autochanger drive 1 = /dev/nst2
1426 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1427 times, not just for multidrive changers. For a 1 drive changer, that's
1433 MTX's manpage (1.2.15):
1434 unload [<slotnum>] [ <drivenum> ]
1435 Unloads media from drive <drivenum> into slot
1436 <slotnum>. If <drivenum> is omitted, defaults to
1437 drive 0 (as do all commands). If <slotnum> is
1438 omitted, defaults to the slot that the drive was
1439 loaded from. Note that there's currently no way
1440 to say 'unload drive 1's media to the slot it
1441 came from', other than to explicitly use that
1442 slot number as the destination.AB

1480 Handling removable disks
1482 From: Karl Cunningham <karlc@keckec.com>
1484 My backups are only to hard disk these days, in removable bays. This is my
1485 idea of how a backup to hard disk would work more smoothly. Some of these
1486 things Bacula does already, but I mention them for completeness. If others
1487 have better ways to do this, I'd like to hear about it.
1489 1. Accommodate several disks, rotated similar to how tapes are. Identified
1490 by partition volume ID or perhaps by the name of a subdirectory.
1491 2. Abort & notify the admin if the wrong disk is in the bay.
1492 3. Write backups to different subdirectories for each machine to be backed
1494 4. Volumes (files) get created as needed in the proper subdirectory, one
1496 5. When a disk is recycled, remove or zero all old backup files. This is
1497 important as the disk being recycled may be close to full. This may be
1498 better done manually since the backup files for many machines may be
1499 scattered in many subdirectories.
1504 - Make sure that all do_prompt() calls in Dir check for
1505 -1 (error) and -2 (cancel) returns.
1506 - Fix foreach_jcr() to have free_jcr() inside next().
1507 jcr=jcr_walk_start();
1508 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1511 - A Volume taken from Scratch should take on the retention period
1513 - Correct doc for Maximum Changer Wait (and others) accepting only
1515 - Implement status that shows why a job is being held in reserve, or
1516 rather why none of the drives are suitable.
1517 - Implement a way to disable a drive (so you can use the second
1518 drive of an autochanger, and the first one will not be used or
1520 - Make sure Maximum Volumes is respected in Pools when adding
1521 Volumes (e.g. when pulling a Scratch volume).
1522 - Keep same dcr when switching device ...
1523 - Implement code that makes the Dir aware that a drive is an
1524 autochanger (so the user doesn't need to use the Autochanger = yes
1526 - Make catalog respect ACL.
1527 - Add recycle count to Media record.
1528 - Add initial write date to Media record.
1529 - Fix store_yesno to be store_bitmask.
