9 - Document cleaning up the spool files:
10 db, pid, state, bsr, mail, conmsg, spool
11 - Document the multiple-drive-changer.txt script.
12 - Pruning with Admin job.
13 - Does WildFile match against full name? Doc.
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 - Correct the Include syntax in the m4.xxx files in examples/conf
27 - Get Perl replacement for bregex.c
28 - Make base64.c (bin_to_base64) take a buffer length
29 argument to avoid overruns.
30 and verify that other buffers cannot overrun.
31 - Implement VolumeState as discussed with Arno.
32 - Document techniques for restoring large numbers of files.
33 - Document setting my.cnf to big file usage.
34 - Add example of proper index output to doc.
36 - Fix re-read of last block to check if job has actually written
37 a block, and check if block was written by a different job
38 (i.e. multiple simultaneous jobs writing).
39 - JobStatus and Termination codes.
40 - Some users claim that they must do two prune commands to get a
41 Volume marked as purged.
42 - Print warning message if LANG environment variable does not specify
44 - New dot commands from Arno.
45 .update volume [enabled|disabled|*see below]
46 .show device=xxx lists information from one storage device, including
47 devices (I'm not even sure that information exists in the DIR...)
48 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
49 better machine-readable output like "Ok" or "Error busy"
50 .move eject device=xxx toslot=yyy the same as above, but with a new
51 target slot. The catalog should be updated accordingly.
52 .move transfer device=xxx fromslot=yyy toslot=zzz
54 - Given all the problems with FIFOs, I think the solution is to do something a
55 little different, though I will look at the code and see if there is not some
56 simple solution (i.e. some bug that was introduced). What might be a better
57 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
58 write data to a program rather than the FIFO. For example, suppose you
63 Then, I could imagine if you backup and restore this file with a direct
64 reference as is currently done for fifos, instead, during backup Bacula will
67 /home/kern/my-fifo.backup
69 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
72 /home/kern/my-fifo.restore
74 and send the data backed up to stdout. These programs can either be an
75 executable or a shell script and they need only read/write to stdin/stdout.
77 I think this would give a lot of flexibility to the user without making any
78 significant changes to Bacula.
83 select FilenameId from Filename where Name='';

104 Client | PoolResidence | Volume | JobName | SQLquery
105 Migration Selection Pattern = "regexp"
106 Next Pool = <override>
109 There should be no need for a Level (migration is always Full, since you
110 don't calculate differential/incremental differences for migration),
111 Storage should be determined by the volume types in the pool, and Client
112 is really a selection issue. Migration should always occur to the
113 NextPool defined in the pool definition. If no nextpool is defined, the
114 job should end with a reason of "no place to go". If Next Pool statement
115 is present, we override the check in the pool definition and use the
118 Here's how I'd define Migration Selection Types:
121 Client -- Migrate data from selected client only. Migration Selection
122 Pattern regexp provides pattern to select client names, eg ^FS00* makes
123 all client names starting with FS00 eligible for migration.
125 Jobname -- Migration all jobs matching name. Migration Selection Pattern
126 regexp provides pattern to select jobnames existing in pool.
128 Volume -- Migrate all data on specified volumes. Migration Selection
129 Pattern regexp provides selection criteria for volumes to be migrated.
130 Volumes must exist in pool to be eligible for migration.
134 LowestUtil -- Identify the volume in the pool with the least data on it
135 and empty it. No Migration Selection Pattern required.
137 OldestVol -- Identify the LRU volume with data written, and empty it. No
138 Migration Selection Pattern required.
140 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
141 (starting with most full volumes) until pool occupancy drops below
142 <lowmig>. Pool highmig and lowmig values are in pool definition, no
143 Migration Selection Pattern required.
147 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
148 Migration Selection Pattern contains SQL query to execute; should return
149 a list of 1 or more jobuids to migrate.
151 PoolResidence -- Migrate data sitting in pool for longer than
152 PoolResidence value in pool definition. Migration Selection Pattern
153 optional; if specified, override value in pool definition (value in

269 - Add VolumeState (enable, disable, archive)
270 - Add VolumeLock to prevent all but lock holder (SD) from updating
271 the Volume data (with the exception of VolumeState).
272 - The btape fill command does not seem to use the Autochanger
273 - Make Windows installer default to system disk drive.

306 that fails, skip to the next file and try again, ...

320 - Look at simplifying File exclusions.
321 - New directive "Delete purged Volumes"
322 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
323 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
324 see if it become stable and I just have to supervise

327 PoolId, and when it is empty remove it.
328 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
330 - Allow Check Labels to be used with Bacula labels.
331 - "Resuming" a failed backup (lost line for example) by using the
332 failed backup as a sort of "base" job.
334 - Email to the user when the tape is about to need changing x
335 days before it needs changing.
336 - Command to show next tape that will be used for a job even
337 if the job is not scheduled.
338 - From: Arunav Mandal <amandal@trolltech.com>
339 1. When jobs are running and bacula for some reason crashes or if I do a
340 restart it remembers and jobs it was running before it crashed or restarted
341 as of now I loose all jobs if I restart it.
343 2. When spooling and in the midway if client is disconnected for instance a
344 laptop bacula completely discard the spool. It will be nice if it can write
345 that spool to tape so there will be some backups for that client if not all.
347 3. We have around 150 clients machines it will be nice to have a option to
348 upgrade all the client machines bacula version automatically.
350 4. Atleast one connection should be reserved for the bconsole so at heavy load
351 I should connect to the director via bconsole which at sometimes I can't
353 5. Another most important feature that is missing, say at 10am I manually
354 started backup of client abc and it was a full backup since client abc has
355 no backup history and at 10.30am bacula again automatically started backup of
356 client abc as that was in the schedule. So now we have 2 multiple Full
357 backups of the same client and if we again try to start a full backup of
358 client backup abc bacula won't complain. That should be fixed.
360 - Fix bpipe.c so that it does not modify results pointer.
361 ***FIXME*** calling sequence should be changed.
362 - For Windows disaster recovery see http://unattended.sf.net/
363 - regardless of the retention period, Bacula will not prune the
364 last Full, Diff, or Inc File data until a month after the
365 retention period for the last Full backup that was done.
366 - update volume=xxx --- add status=Full
367 - Remove old spool files on startup.
368 - Exclude SD spool/working directory.
369 - Refuse to prune last valid Full backup. Same goes for Catalog.
371 - Make a callback when Rerun failed levels is called.
372 - Give Python program access to Scheduled jobs.
373 - Add setting Volume State via Python.
374 - Python script to save with Python, not save, save with Bacula.
375 - Python script to do backup.
377 - Change the Priority, Client, Storage, JobStatus (error)
378 at the start of a job.
379 - Why is SpoolDirectory = /home/bacula/spool; not reported
380 as an error when writing a DVD?
381 - Make bootstrap file handle multiple MediaTypes (SD)
382 - Remove all old Device resource code in Dir and code to pass it
383 back in SD -- better, rework it to pass back device statistics.
384 - Check locking of resources -- be sure to lock devices where previously
385 resources were locked.
386 - The last part is left in the spool dir.
389 - In restore don't compare byte count on a raw device -- directory
390 entry does not contain bytes.
391 - To mark files as deleted, run essentially a Verify to disk, and
392 when a file is found missing (MarkId != JobId), then create
393 a new File record with FileIndex == -1. This could be done
394 by the FD at the same time as the backup.
398 MA = (last_MA * 3 + rate) / 4
399 rate = (bytes - last_bytes) / (runtime - last_runtime)
400 - Max Vols limit in Pool off by one?
401 - Implement Files/Bytes,... stats for restore job.
402 - Implement Total Bytes Written, ... for restore job.
403 - Despool attributes simultaneously with data in a separate
404 thread, rejoined at end of data spooling.
405 - 7. Implement new Console commands to allow offlining/reserving drives,
406 and possibly manipulating the autochanger (much asked for).
407 - Add start/end date editing in messages (%t %T, %e?) ...
408 - Add ClientDefs similar to JobDefs.
409 - Print more info when bextract -p accepts a bad block.
410 - Fix FD JobType to be set before RunBeforeJob in FD.
411 - Look at adding full Volume and Pool information to a Volume
412 label so that bscan can get *all* the info.
413 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
414 and there is only one volume in the pool, refuse to do it -- otherwise
415 he fills the Volume, then immediately starts reusing it.
416 - Implement copies and stripes.
417 - Add history file to console.
418 - Each file on tape creates a JobMedia record. Peter has 4 million
419 files spread over 10000 tape files and four tapes. A restore takes
420 16 hours to build the restore list.
421 - Add and option to check if the file size changed during backup.
422 - Make sure SD deletes spool files on error exit.
423 - Delete old spool files when SD starts.
424 - When labeling tapes, if you enter 000026, Bacula uses
425 the tape index rather than the Volume name 000026.
426 - Add offline tape command to Bacula console.
428 Enter MediaId or Volume name: 32
429 Enter new Volume name: DLT-20Dec04
430 Automatically selected Pool: Default
431 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

437 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
438 Label command failed for Volume DLT-20Dec04.
439 Do not forget to mount the drive!!!
440 - Bug: if a job is manually scheduled to run later, it does not appear
441 in any status report and cannot be cancelled.
443 ==== Keeping track of deleted files ====
444 My "trick" for keeping track of deletions is the following.
445 Assuming the user turns on this option, after all the files
446 have been backed up, but before the job has terminated, the
447 FD will make a pass through all the files and send their
448 names to the DIR (*exactly* the same as what a Verify job
449 currently does). This will probably be done at the same
450 time the files are being sent to the SD avoiding a second
451 pass. The DIR will then compare that to what is stored in
452 the catalog. Any files in the catalog but not in what the
453 FD sent will receive a catalog File entry that indicates
454 that at that point in time the file was deleted.
456 During a restore, any file initially picked up by some
457 backup (Full, ...) then subsequently having a File entry
458 marked "delete" will be removed from the tree, so will not
459 be restored. If a file with the same name is later OK it
460 will be inserted in the tree -- this already happens. All
461 will be consistent except for possible changes during the
464 Since I'm on the subject, some of you may be wondering what
465 the utility of the in memory tree is if you are going to
466 restore everything (at least it comes up from time to time
467 on the list). Well, it is still *very* useful because it
468 allows only the last item found for a particular filename
469 (full path) to be entered into the tree, and thus if a file
470 is backed up 10 times, only the last copy will be restored.
471 I recently (last Friday) restored a complete directory, and
472 the Full and all the Differential and Incremental backups
473 spanned 3 Volumes. The first Volume was not even mounted
474 because all the files had been updated and hence backed up
475 since the Full backup was made. In this case, the tree
476 saved me a *lot* of time.
478 Make sure this information is stored on the tape too so
479 that it can be restored directly from the tape.
481 Comments from Martin Simmons (I think they are all covered):
482 Ok, that should cover the basics. There are few issues though:
484 - Restore will depend on the catalog. I think it is better to include the
485 extra data in the backup as well, so it can be seen by bscan and bextract.
487 - I'm not sure if it will preserve multiple hard links to the same inode. Or
488 maybe adding or removing links will cause the data to be dumped again?
490 - I'm not sure if it will handle renamed directories. Possibly it will work
491 by dumping the whole tree under a renamed directory?
493 - It remains to be seen how the backup performance of the DIR's will be
494 affected when comparing the catalog for a large filesystem.
498 How about introducing a Type = MgmtPolicy job type? That job type would
499 be responsible for scanning the Bacula environment looking for specific
500 conditions, and submitting the appropriate jobs for implementing said
504 Name = "Migration-Policy"
506 Policy Selection Job Type = Migrate
507 Scope = "<keyword> <operator> <regexp>"
508 Threshold = "<keyword> <operator> <regexp>"
509 Job Template = <template-name>
512 Where <keyword> is any legal job keyword, <operator> is a comparison
513 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
514 appropriate regexp. I could see an argument for Scope and Threshold
515 being SQL queries if we want to support full flexibility. The
516 Migration-Policy job would then get scheduled as frequently as a site
517 felt necessary (suggested default: every 15 minutes).
522 Name = "Migration-Policy"
524 Policy Selection Job Type = Migration
526 Threshold = "Migration Selection Type = LowestUtil"
527 Job Template = "MigrationTemplate"
530 would select all pools for examination and generate a job based on
531 MigrationTemplate to automatically select the volume with the lowest
532 usage and migrate it's contents to the nextpool defined for that pool.
534 This policy abstraction would be really handy for adjusting the behavior
535 of Bacula according to site-selectable criteria (one thing that pops
536 into mind is Amanda's ability to automatically adjust backup levels
537 depending on various criteria).
543 - Add Pool/Storage override regression test.
544 - Add delete JobId to regression.
545 - Add a regression test for dbcheck.
546 - New test to add bscan to four-concurrent-jobs regression,
547 i.e. after the four-concurrent jobs zap the
548 database as is done in the bscan-test, then use bscan to
549 restore the database, do a restore and compare with the

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

570 === From Carsten Menke <bootsy52@gmx.net>
572 Following is a list of what I think in the situations where I'm faced with,
573 could be a usefull enhancement to bacula, which I'm certain other users will
574 benefit from as well.
576 1. NextJob/NextJobs Directive within a Job Resource in the form of
577 NextJobs = job1,job2.
580 I currently solved the problem with running multiple jobs each after each
581 by setting the Max Wait Time for a job to 8 hours, and give
582 the jobs different Priorities. However, there scenarios where
583 1 Job is directly depending on another job, so if the former job fails,
584 the job after it needn't to be run
585 while maybe other jobs should run despite of that
588 A Backup Job and a Verify job, if the backup job fails there is no need to run
589 the verify job, as the backup job already failed. However, one may like
590 to backup the Catalog to disk despite of that the main backup job failed.
593 I see that this is related to the Event Handlers which are on the ToDo
594 list, also it is maybe a good idea to check for the return value and
595 execute different actions based on the return value
598 3. offline capability to bconsole
601 Currently I use a script which I execute within the last Job via the
602 RunAfterJob Directive, to release and eject the tape.
603 So I have to call bconsole "release=Storage-Name" and afterwards
604 mt -f /dev/nst0 eject to get the tape out.
606 If I have multiple Storage Devices, than these may not be /dev/nst0 and
607 I have to modify the script or call it with parameters etc.
608 This would actually not be needed, as everything is already defined
609 in bacula-sd.conf and if I can invoke bconsole with the
610 storage name via $1 in the script than I'm done and information is
613 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
617 For the reason mentioned in 3. to have the ability to call a
618 script with /scripts/foobar %s and in the script use $1
619 to pass the Storage Name to bconsole
621 5. Setting Volume State within a Job Resource
624 Instead of using "Maximum Volume Jobs" in the Pool Resource,
625 I would have the possibilty to define
626 in a Job Resource that after this certain job is run, the Volume State
627 should be set to "Volume State = Used", this give more flexibility (IMHO).
629 6. Localization of Bacula Messages
632 Unfortunatley many,many people I work with don't speak english very well.
633 So if at least the Reporting messages would be localized then they
634 would understand that they have to change the tape,etc. etc.
636 I volunteer to do the german translations, and if I can convince my wife also
637 french and Morre (western african language).
639 7. OK, this is evil, probably bound to security risks and maybe not possible
640 due to the design of bacula.
642 Implementation of Backtics ( `command` ) for shell comand execution to
643 the "Label Format" Directive.
647 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
648 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
649 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
650 the localized name for the day of the week appended to the
651 format string. Then I have the tape labeled automatically with weekday
652 name in the correct language.
654 - Yes, that is surely the case. I probably should turn those into Warning
655 errors. In addition, you just made me think that it might not be bad to
656 add an option to check the file size after backing up the file and
657 report if it changes. This would be done as an option because it would
660 Kern, good idea. If you do do that, mention in the output: file
661 shrunk, or file expanded, just to make it obvious to the user
662 (without having to the refer to file size), just how the file size
665 Would this option be for all file, or just one file? Or a fileset?
666 - Make output from status use html table tags for nicely
667 presenting in a browser.
668 - Can one write tapes faster with 8192 byte block sizes?
669 - Document security problems with the same password for everyone in
670 rpm and Win32 releases.
671 - Browse generations of files.
672 - I've seen an error when my catalog's File table fills up. I
673 then have to recreate the File table with a larger maximum row
674 size. Relevant information is at
675 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
676 "Installing and Configuring MySQL" chapter should talk a bit
677 about this potential problem, and recommend a solution.
678 - For Solaris must use POSIX awk.
679 - Want speed of writing to tape while despooling.
680 - Supported autochanger:
688 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
689 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
690 - Add regex from http://www.pcre.org to Bacula for Win32.
691 - Use only shell tools no make in CDROM package.
692 - Include within include does it work?
693 - Implement a Pool of type Cleaning?
694 - Implement VolReadTime and VolWriteTime in SD
695 - Modify Backing up Your Database to include a bootstrap file.
696 - Think about making certain database errors fatal.
697 - Look at correcting the time jump in the scheduler for daylight
698 savings time changes.
699 - Add a "real" timer to network connections.
700 - Promote to Full = Time period
701 - Check dates entered by user for correctness (month/day/... ranges)
702 - Compress restore Volume listing by date and first file.
703 - Look at patches/bacula_db.b2z postgresql that loops during restore.
705 - Perhaps add read/write programs and/or plugins to FileSets.
706 - How to handle backing up portables ...
707 - Add some sort of guaranteed Interval for upgrading jobs.
708 - Can we write the state file after every job terminates? On Win32
709 the system crashes and the state file is not updated.
712 Documentation to do: (any release a little bit at a time)
713 - Doc to do unmount before removing magazine.
714 - Alternative to static linking "ldd prog" save all binaries listed,
715 restore them and point LD_LIBRARY_PATH to them.
716 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
717 - Document query file format.
718 - Add more documentation for bsr files.
719 - Document problems with Verify and pruning.
720 - Document how to use multiple databases.
721 - VXA drives have a "cleaning required"
722 indicator, but Exabyte recommends preventive cleaning after every 75
725 In this context, it should be noted that Exabyte has a command-line
726 vxatool utility available for free download. (The current version is
727 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
728 test the drive, unload tapes, change drive settings, flash new firmware,
730 Of particular interest in this context is that vxatool <device> -i will
731 report, among other details, the time since last cleaning in tape motion
732 minutes. This information can be retrieved (and settings changed, for
733 that matter) through the generic-SCSI device even when Bacula has the
734 regular tape device locked. (Needless to say, I don't recommend
735 changing tape settings while a job is running.)
736 - Lookup HP cleaning recommendations.
737 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
738 - Document doing table repair
741 ===================================
742 - Add macro expansions in JobDefs.
743 Run Before Job = "SomeFile %{Level} %{Client}"
744 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
745 - Use non-blocking network I/O but if no data is available, use
747 - Use gather write() for network I/O.
748 - Autorestart on crash.
749 - Add bandwidth limiting.
750 - Add acks every once and a while from the SD to keep
751 the line from timing out.
752 - When an error in input occurs and conio beeps, you can back
753 up through the prompt.
754 - Detect fixed tape block mode during positioning by looking at
755 block numbers in btape "test". Possibly adjust in Bacula.
756 - Fix list volumes to output volume retention in some other
757 units, perhaps via a directive.
758 - If opening a tape in read/write mode fails attempt to open
759 it in read-only mode, and mark the tape for read only.
760 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
761 with multiple priorities.
762 - If you use restore replace=never, the directory attributes for
763 non-existent directories will not be restored properly.
765 - see lzma401.zip in others directory for new compression
767 - Minimal autochanger handling in Bacula and in btape.
768 - Look into how tar does not save sockets and the possiblity of
769 not saving them in Bacula (Martin Simmons reported this).
770 - Fix restore jobs so that multiple jobs can run if they
771 are not using the same tape(s).
772 - Allow the user to select JobType for manual pruning/purging.
773 - bscan does not put first of two volumes back with all info in
775 - Implement the FreeBSD nodump flag in chflags.
776 - Figure out how to make named console messages go only to that
777 console and to the non-restricted console (new console class?).
778 - Make restricted console prompt for password if *ask* is set or
779 perhaps if password is undefined.
780 - Implement "from ISO-date/time every x hours/days/weeks/months" in
783 ==== from Marc Schoechlin
784 - the help-command should be more verbose
785 (it should explain the paramters of the different
787 -> its time-comsuming to consult the manual anytime
788 you need a special parameter
789 -> maybe its more easy to maintain this, if the
790 descriptions of that commands are outsourced to
792 - the cd-command should allow complete paths
793 i.e. cd /foo/bar/foo/bar
794 -> if a customer mails me the path to a certain file,
795 its faster to enter the specified directory
796 - if the password is not configured in bconsole.conf
797 you should be asked for it.
798 -> sometimes you like to do restore on a customer-machine
799 which shouldnt know the password for bacula.
800 -> adding the password to the file favours admins
801 to forget to remove the password after usage
803 the protection of that file is less important
804 - long-listed-output of commands should be scrollable
805 like the unix more/less-command does
806 -> if someone runs 200 and more machines, the lists could
807 be a little long and complex
808 - command-output should be shown column by column
809 to reduce scrolling and to increase clarity
811 - lsmark should list the selected files with full
813 - wildcards for selecting and file and directories would be nice
814 - any actions should be interuptable with STRG+C
815 - command-expansion would be pretty cool
817 - When the replace Never option is set, new directory permissions
818 are not restored. See bug 213. To fix this requires creating a
819 list of newly restored directories so that those directory
820 permissions *can* be restored.
821 - Compaction of Disk space by "migrating" Volumes that have pruned
822 Jobs (what criteria? size, #jobs, time).
823 - Add prune all command
824 - Document fact that purge can destroy a part of a restore by purging
825 one volume while others remain valid -- perhaps mark Jobs.
826 - Add multiple-media-types.txt
827 - look at mxt-changer.html
828 - Make ? do a help command (no return needed).
829 - Implement restore directory.
830 - Document streams and how to implement them.
831 - Try not to re-backup a file if a new hard link is added.
832 - Add feature to backup hard links only, but not the data.
833 - Fix stream handling to be simpler.
834 - Add Priority and Bootstrap to Run a Job.
835 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
837 - Remove View FileSet button from Run a Job dialog.
838 - Handle prompt for restore job at end of Restore command.
839 - Add display of total selected files to Restore window.
840 - Add tree pane to left of window.
841 - Add progress meter.
842 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
843 - Document writing to a CD/DVD with Bacula.
844 - Add a "base" package to the window installer for pthreadsVCE.dll
845 which is needed by all packages.
846 - Add message to user to check for fixed block size when the forward
847 space test fails in btape.
848 - When unmarking a directory check if all files below are unmarked and
849 then remove the + flag -- in the restore tree.
850 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
851 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
852 - Revisit the question of multiple Volumes (disk) on a single device.
853 - Add a block copy option to bcopy.
854 - Investigate adding Mac Resource Forks.
855 - Finish work on Gnome restore GUI.
856 - Fix "llist jobid=xx" where no fileset or client exists.
857 - For each job type (Admin, Restore, ...) require only the really necessary
858 fields.- Pass Director resource name as an option to the Console.
859 - Add a "batch" mode to the Console (no unsolicited queries, ...).
860 - Add a .list all files in the restore tree (probably also a list all files)
861 Do both a long and short form.
862 - Allow browsing the catalog to see all versions of a file (with
863 stat data on each file).
864 - Restore attributes of directory if replace=never set but directory
866 - Use SHA1 on authentication if possible.
867 - See comtest-xxx.zip for Windows code to talk to USB.
868 - Add John's appended files:
869 Appended = { /files/server/logs/http/*log }
870 and such files would be treated as follows.On a FULL backup, they would
871 be backed up like any other file.On an INCREMENTAL backup, where a
872 previous INCREMENTAL or FULL was already in thecatalogue and the length
873 of the file wasgreater than the length of the last backup, only thedata
874 added since the last backup will be dumped.On an INCREMENTAL backup, if
875 the length of the file is less than thelength of the file with the same
876 name last backed up, the completefile is dumped.On Windows systems, with
877 creation date of files, we can be evensmarter about this and not count
878 entirely upon the length.On a restore, the full and all incrementals
879 since it will beapplied in sequence to restore the file.
880 - Check new HAVE_WIN32 open bits.
881 - Check if the tape has moved before writing.
882 - Handling removable disks -- see below:
883 - Keep track of tape use time, and report when cleaning is necessary.
884 - Add FromClient and ToClient keywords on restore command (or
885 BackupClient RestoreClient).
886 - Implement a JobSet, which groups any number of jobs. If the
887 JobSet is started, all the jobs are started together.
888 Allow Pool, Level, and Schedule overrides.
889 - Enhance cancel to timeout BSOCK packets after a specific delay.
890 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
891 ua_status.!!! Thanks to Alan Brown for this tip.
892 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
893 correctly for multiple simultaneous jobs.
894 - Correct code so that FileSet MD5 is calculated for < and | filename
896 - Implement the Media record flag that indicates that the Volume does disk
898 - Implement VolAddr, which is used when Volume is addressed like a disk,
899 and form it from VolFile and VolBlock.
900 - Make multiple restore jobs for multiple media types specifying
901 the proper storage type.
902 - Fix fast block rejection (stored/read_record.c:118). It passes a null
903 pointer (rec) to try_repositioning().
904 - Look at extracting Win data from BackupRead.
905 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
906 which would take precidence over the Catalog "JobRetention".
907 - Implement Label Format in Add and Label console commands.
908 - Possibly up network buffers to 65K. Put on variable.
909 - Put email tape request delays on one or more variables. User wants
910 to cancel the job after a certain time interval. Maximum Mount Wait?
911 - Job, Client, Device, Pool, or Volume?
912 Is it possible to make this a directive which is *optional* in multiple
913 resources, like Level? If so, I think I'd make it an optional directive
914 in Job, Client, and Pool, with precedence such that Job overrides Client
915 which in turn overrides Pool.
917 - New Storage specifications:
918 - Want to write to multiple storage devices simultaneously
919 - Want to write to multiple storage devices sequentially (in one job)
920 - Want to read/write simultaneously
921 - Key is MediaType -- it must match
923 Passed to SD as a sort of BSR record called Storage Specification
927 MediaType -> Next MediaType
929 Device -> Next Device
931 Allow multiple Storage specifications
939 Allow Multiple Pool specifications (note, Pool currently
941 Allow Multiple MediaType specifications in Dir conf
942 Allow Multiple Device specifications in Dir conf
943 Perhaps keep this in a single SSR
944 Tie a Volume to a specific device by using a MediaType that
945 is contained in only one device.
946 In SD allow Device to have Multiple MediaTypes
948 - Ideas from Jerry Scharf:
949 First let's point out some big pluses that bacula has for this
951 more importantly it's active. Thank you so much for that
952 even more important, it's not flaky
953 it has an open access catalog, opening many possibilities
954 it's pushing toward heterogeneous systems capability
956 Macintosh file client
957 macs are an interesting niche, but I fear a server is a rathole
958 working bare iron recovery for windows
959 the option for inc/diff backups not reset on fileset revision
960 a) use both change and inode update time against base time
961 b) do the full catalog check (expensive but accurate)
962 sizing guide (how much system is needed to back up N systems/files)
963 consultants on using bacula in building a disaster recovery system
965 or how to get at fancy things that one could do with bacula
966 logwatch code for bacula logs (or similar)
967 linux distro inclusion of bacula (brings good and bad, but necessary)
968 win2k/XP server capability (icky but you asked)
969 support for Oracle database ??
971 - Look at adding SQL server and Exchange support for Windows.
972 - Make dev->file and dev->block_num signed integers so that -1 can
973 be an invalid value which happens with BSR.
974 - Create VolAddr for disk files in place of VolFile and VolBlock. This
975 is needed to properly specify ranges.
976 - Add progress of files/bytes to SD and FD.
977 - Print warning message if FileId > 4 billion
978 - do a "messages" before the first prompt in Console
979 - Client does not show busy during Estimate command.
980 - Implement Console mtx commands.
981 - Implement a Mount Command and an Unmount Command where
982 the users could specify a system command to be performed
983 to do the mount, after which Bacula could attempt to
984 read the device. This is for Removeable media such as a CDROM.
985 - Most likely, this mount command would be invoked explicitly
986 by the user using the current Console "mount" and "unmount"
987 commands -- the Storage Daemon would do the right thing
988 depending on the exact nature of the device.
989 - As with tape drives, when Bacula wanted a new removable
990 disk mounted, it would unmount the old one, and send a message
991 to the user, who would then use "mount" as described above
992 once he had actually inserted the disk.
993 - Implement dump/print label to UA
994 - Spool to disk only when the tape is full, then when a tape is hung move
996 - bextract is sending everything to the log file ****FIXME****
997 - Allow multiple Storage specifications (or multiple names on
998 a single Storage specification) in the Job record. Thus a job
999 can be backed up to a number of storage devices.
1000 - Implement some way for the File daemon to contact the Director
1001 to start a job or pass its DHCP obtained IP number.
1002 - Implement a query tape prompt/replace feature for a console
1003 - Copy console @ code to gnome2-console
1004 - Make AES the only encryption algorithm see
1005 http://csrc.nist.gov/CryptoToolkit/aes/). It's
1006 an officially adopted standard, has survived peer
1007 review, and provides keys up to 256 bits.
1008 - Take a careful look at SetACL http://setacl.sourceforge.net
1009 - Make tree walk routines like cd, ls, ... more user friendly
1010 by handling spaces better.
1011 - Make sure that Bacula rechecks the tape after the 20 min wait.
1012 - Set IO_NOWAIT on Bacula TCP/IP packets.
1013 - Try doing a raw partition backup and restore by mounting a
1015 - From Lars Kellers:
1016 Yes, it would allow to highly automatic the request for new tapes. If a
1017 tape is empty, bacula reads the barcodes (native or simulated), and if
1018 an unused tape is found, it runs the label command with all the
1019 necessary parameters.
1021 By the way can bacula automatically "move" an empty/purged volume say
1022 in the "short" pool to the "long" pool if this pool runs out of volume
1024 - What to do about "list files job=xxx".
1025 - Get and test MySQL 4.0
1026 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1027 file descriptor leak in Bacula.
1028 - Implement WrapCounters in Counters.
1029 - Add heartbeat from FD to SD if hb interval expires.
1030 - Can we dynamically change FileSets?
1031 - If pool specified to label command and Label Format is specified,
1032 automatically generate the Volume name.
1033 - Why can't SQL do the filename sort for restore?
1034 - Add ExhautiveRestoreSearch
1035 - Look at the possibility of loading only the necessary
1036 data into the restore tree (i.e. do it one directory at a
1037 time as the user walks through the tree).
1038 - Possibly use the hash code if the user selects all for a restore command.
1039 - Fix "restore all" to bypass building the tree.
1040 - Prohibit backing up archive device (findlib/find_one.c:128)
1041 - Implement Release Device in the Job resource to unmount a drive.
1042 - Implement Acquire Device in the Job resource to mount a drive,
1043 be sure this works with admin jobs so that the user can get
1044 prompted to insert the correct tape. Possibly some way to say to
1045 run the job but don't save the files.
1046 - Make things like list where a file is saved case independent for
1049 - Use autochanger to handle multiple devices.
1050 - On Windows with very long path names, it may be impossible to create
1051 a file (and thus restore it) because the total length is too long.
1052 We must cd into the directory then create the file without the
1054 - Implement a Recycle command
1055 - Test a second language e.g. french.
1056 - Start working on Base jobs.
1057 - Implement UnsavedFiles DB record.
1058 - From Phil Stracchino:
1059 It would probably be a per-client option, and would be called
1060 something like, say, "Automatically purge obsoleted jobs". What it
1061 would do is, when you successfully complete a Differential backup of a
1062 client, it would automatically purge all Incremental backups for that
1063 client that are rendered redundant by that Differential. Likewise,
1064 when a Full backup on a client completed, it would automatically purge
1065 all Differential and Incremental jobs obsoleted by that Full backup.
1066 This would let people minimize the number of tapes they're keeping on
1067 hand without having to master the art of retention times.
1068 - When doing a Backup send all attributes back to the Director, who
1069 would then figure out what files have been deleted.
1070 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1071 explicit permission to do so. It should also mark the tape in error
1072 if there is an error.
1073 - Cancel waiting for Client connect in SD if FD goes away.
1075 - Implement timeout in response() when it should come quickly.
1076 - Implement a Slot priority (loaded/not loaded).
1077 - Implement "vacation" Incremental only saves.
1078 - Implement create "FileSet"?
1079 - Add prefixlinks to where or not where absolute links to FD.
1080 - Issue message to mount a new tape before the rewind.
1081 - Simplified client job initiation for portables.
1082 - If SD cannot open a drive, make it periodically retry.
1083 - Add more of the config info to the tape label.
1085 - If tape is marked read-only, then try opening it read-only rather than
1086 failing, and remember that it cannot be written.
1087 - Refine SD waiting output:
1088 Device is being positioned
1089 > Device is being positioned for append
1090 > Device is being positioned to file x
1092 - Figure out some way to estimate output size and to avoid splitting
1093 a backup across two Volumes -- this could be useful for writing CDROMs
1094 where you really prefer not to have it split -- not serious.
1095 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1096 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1097 actual data on the Volume and compare it.
1098 - Implement Bacula plugins -- design API
1099 - Make bcopy read through bad tape records.
1100 - Program files (i.e. execute a program to read/write files).
1101 Pass read date of last backup, size of file last time.
1102 - Add Signature type to File DB record.
1103 - CD into subdirectory when open()ing files for backup to
1104 speed up things. Test with testfind().
1105 - Priority job to go to top of list.
1106 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1107 - Implement some way for the Console to dynamically create a job.
1108 - Solaris -I on tar for include list
1109 - Need a verbose mode in restore, perhaps to bsr.
1110 - bscan without -v is too quiet -- perhaps show jobs.
1111 - Add code to reject whole blocks if not wanted on restore.
1112 - Check if we can increase Bacula FD priorty in Win2000
1113 - Make sure the MaxVolFiles is fully implemented in SD
1114 - Check if both CatalogFiles and UseCatalog are set to SD.
1115 - Possibly add email to Watchdog if drive is unmounted too
1116 long and a job is waiting on the drive.
1117 - After unmount, if restore job started, ask to mount.
1118 - Add UA rc and history files.
1119 - put termcap (used by console) in ./configure and
1120 allow -with-termcap-dir.
1121 - Fix Autoprune for Volumes to respect need for full save.
1122 - Compare tape to Client files (attributes, or attributes and data)
1123 - Make all database Ids 64 bit.
1124 - Allow console commands to detach or run in background.
1125 - Fix status delay on storage daemon during rewind.
1126 - Add SD message variables to control operator wait time
1127 - Maximum Operator Wait
1128 - Minimum Message Interval
1129 - Maximum Message Interval
1130 - Send Operator message when cannot read tape label.
1131 - Verify level=Volume (scan only), level=Data (compare of data to file).
1132 Verify level=Catalog, level=InitCatalog
1134 - Add keyword search to show command in Console.
1135 - Events : tape has more than xxx bytes.
1136 - Complete code in Bacula Resources -- this will permit
1137 reading a new config file at any time.
1138 - Handle ctl-c in Console
1139 - Implement script driven addition of File daemon to config files.
1140 - Think about how to make Bacula work better with File (non-tape) archives.
1141 - Write Unix emulator for Windows.

1166 - Autolabel should be specified by DIR instead of SD.
1168 - Add media capacity
1169 - AutoScan (check checksum of tape)
1170 - Format command = "format /dev/nst0"
1174 - Seek resolution (usually corresponds to buffer size)
1175 - EODErrorCode=ENOSPC or code
1176 - Partial Read error code
1177 - Partial write error code
1178 - Nonformatted read error
1179 - Nonformatted write error
1180 - WriteProtected error
1184 - IgnoreCloseErrors=yes
1194 - FD sends unsaved file list to Director at end of job (see
1196 - File daemon should build list of files skipped, and then
1197 at end of save retry and report any errors.
1198 - Write a Storage daemon that uses pipes and
1199 standard Unix programs to write to the tape.
1201 - Need something that monitors the JCR queue and
1202 times out jobs by asking the deamons where they are.
1203 - Enhance Jmsg code to permit buffering and saving to disk.
1204 - device driver = "xxxx" for drives.
1205 - Verify from Volume
1206 - Ensure that /dev/null works
1207 - Need report class for messages. Perhaps
1208 report resource where report=group of messages
1209 - enhance scan_attrib and rename scan_jobtype, and
1210 fill in code for "since" option
1211 - Director needs a time after which the report status is sent
1212 anyway -- or better yet, a retry time for the job.
1213 - Don't reschedule a job if previous incarnation is still running.
1214 - Some way to automatically backup everything is needed????
1215 - Need a structure for pending actions:
1217 - termination status (part of buffered msgs?)
1219 Read, Write, Clean, Delete
1220 - Login to Bacula; Bacula users with different permissions:
1221 owner, group, user, quotas
1222 - Store info on each file system type (probably in the job header on tape.
1223 This could be the output of df; or perhaps some sort of /etc/mtab record.

1228 Subject: RE: [Bacula-users] future large programming jobs
1229 Date: Thu, 26 Feb 2004 11:34:54 -0600
1231 I noticed the subject thread and thought I would offer the following
1232 merely as sources of ideas, i.e. something to think about, not even as
1233 strong as a request. In my former life (before retiring) I often
1234 dealt with backups and storage management issues/products as a
1235 developer and as a consultant. I am currently migrating my personal
1236 network from amanda to bacula specifically because of the ability to
1237 cross media boundaries during storing backups.
1238 Are you familiar with the commercial product called ADSM (I think IBM
1239 now sells it under the Tivoli label)? It has a couple of interesting
1240 ideas that may apply to the following topics.
1242 1. Migration: Consider that when you need to restore a system, there
1243 may be pressure to hurry. If all the information for a single client
1244 can eventually end up on the same media (and in chronological order),
1245 the restore is facillitated by not having to search past information
1246 from other clients. ADSM has the concept of "client affinity" that
1247 may be associated with it's storage pools. It seems to me that this
1248 concept (as an optional feature) might fit in your architecture for
1251 ADSM also has the concept of defining one or more storage pools as
1252 "copy pools" (almost mirrors, but only in the sense of contents).
1253 These pools provide the ability to have duplicte data stored both
1254 onsite and offsite. The copy process can be scheduled to be handled
1255 by their storage manager during periods when there is no backup
1256 activity. Again, the migration process might be a place to consider
1257 implementing something like this.
1260 > It strikes me that it would be very nice to be able to do things
1262 > have the Job(s) backing up the machines run, and once they have all

1268 > mechanism described below would probably make it very easy.
1270 This is the goal. In the first step (before events), you simply
1272 the Migration to tape later.
1274 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1275 the database. Once a file (unique by path and metadata such as dates,
1276 size, ownership, etc.) is in a copy pool, no more copies are made. In
1277 other words, when you start ADSM, it begins like your concept of a
1278 base job. After that it is in the "incremental" mode. You can
1279 configure the number of "generations" of files to be retained, plus a
1280 retention date after which even old generations are purged. The
1281 database tracks the contents of media and projects the percentage of
1282 each volume that is valid. When the valid content of a volume drops
1283 below a configured percentage, the valid data are migrated to another
1284 volume and the old volume is marked as empty. Note, this requires
1285 ADSM to have an idea of the contents of a client, i.e. marking the
1286 database when an existing file was deleted, but this would solve your
1287 issue of restoring a client without restoring deleted files.
1289 This is pretty far from what bacula now does, but if you are going to
1290 rip things up for Base jobs,.....
1291 Also, the benefits of this are huge for very large shops, especially
1292 with media robots, but are a pain for shops with manual media
1296 > Base jobs sound pretty useful, but I'm not dying for them.
1298 Nobody is dying for them, but when you see what it does, you will die
1301 3. Restoring deleted files: Since I think my comments in (2) above
1302 have low probability of implementation, I'll also suggest that you
1303 could approach the issue of deleted files by a mechanism of having the
1304 fd report to the dir, a list of all files on the client for every
1305 backup job. The dir could note in the database entry for each file
1306 the date that the file was seen. Then if a restore as of date X takes
1307 place, only files that exist from before X until after X would be
1308 restored. Probably the major cost here is the extra date container in
1309 each row of the files table.
1311 Thanks for "listening". I hope some of this helps. If you want to
1312 contact me, please send me an email - I read some but not all of the
1313 mailing list traffic and might miss a reply there.
1315 Please accept my compliments for bacula. It is doing a great job for
1316 me!! I sympathize with you in the need to wrestle with excelence in
1317 execution vs. excelence in feature inclusion.
1322 ==============================
1325 - Design at hierarchial storage for Bacula. Migration and Clone.
1326 - Implement FSM (File System Modules).
1327 - Audit M_ error codes to ensure they are correct and consistent.
1328 - Add variable break characters to lex analyzer.
1329 Either a bit mask or a string of chars so that
1330 the caller can change the break characters.
1331 - Make a single T_BREAK to replace T_COMMA, etc.
1332 - Ensure that File daemon and Storage daemon can
1333 continue a save if the Director goes down (this
1334 is NOT currently the case). Must detect socket error,
1335 buffer messages for later.
1336 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1337 - Add ability to backup to two Storage devices (two SD sessions) at
1338 the same time -- e.g. onsite, offsite.
1339 - Add the ability to consolidate old backup sets (basically do a restore
1340 to tape and appropriately update the catalog). Compress Volume sets.
1341 Might need to spool via file is only one drive is available.
1342 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1343 someway to do so with every volume that has less than x% valid
1347 Migration: Move a backup from one Volume to another
1348 Clone: Copy a backup -- two Volumes
1350 Bacula Migration is based on Jobs (apparently Networker is file by file).
1352 Migration triggered by:
1356 Highwater mark (keep total size)
1361 ======================================================
1363 It is somewhat like a Full save becomes an incremental since
1364 the Base job (or jobs) plus other non-base files.
1366 - A Base backup is same as Full backup, just different type.
1367 - New BaseFiles table that contains:
1369 BaseJobId - Base JobId referenced for this FileId (needed ???)
1370 JobId - JobId currently running
1371 FileId - File not backed up, exists in Base Job
1372 FileIndex - FileIndex from Base Job.
1373 i.e. for each base file that exists but is not saved because
1374 it has not changed, the File daemon sends the JobId, BaseId,
1375 FileId, FileIndex back to the Director who creates the DB entry.
1376 - To initiate a Base save, the Director sends the FD
1377 the FileId, and full filename for each file in the Base.
1378 - When the FD finds a Base file, he requests the Director to
1379 send him the full File entry (stat packet plus MD5), or
1380 conversely, the FD sends it to the Director and the Director
1381 says yes or no. This can be quite rapid if the FileId is kept
1382 by the FD for each Base Filename.
1383 - It is probably better to have the comparison done by the FD
1384 despite the fact that the File entry must be sent across the
1386 - An alternative would be to send the FD the whole File entry
1387 from the start. The disadvantage is that it requires a lot of
1388 space. The advantage is that it requires less communications
1390 - The Job record must be updated to indicate that one or more
1392 - At end of Job, FD returns:
1393 1. Count of base files/bytes not written to tape (i.e. matches)
1394 2. Count of base file that were saved i.e. had changed.
1395 - No tape record would be written for a Base file that matches, in the
1396 same way that no tape record is written for Incremental jobs where
1397 the file is not saved because it is unchanged.
1398 - On a restore, all the Base file records must explicitly be
1399 found from the BaseFile tape. I.e. for each Full save that is marked
1400 to have one or more Base Jobs, search the BaseFile for all occurrences
1402 - An optimization might be to make the BaseFile have:
1408 This would avoid the need to explicitly fetch each File record for
1409 the Base job. The Base Job record will be fetched to get the
1410 VolSessionId and VolSessionTime.
1411 =========================================================
1414 ==========================================================
1416 For each Incremental job that is run, there may be files that
1417 were found but not saved because they were locked (this applies
1418 only to Windows). Such a system could send back to the Director
1419 a list of Unsaved files.
1421 - New UnSavedFiles table that contains:
1425 - Then in the next Incremental job, the list of Unsaved Files will be
1426 feed to the FD, who will ensure that they are explicitly chosen even
1427 if standard date/time check would not have selected them.
1428 =============================================================

1469 (just to verify it remembers where it came from, however it can be

1472 There needs to be a table of drive # to devices somewhere - If there are
1473 multiple changers or drives there may not be a 1:1 correspondance between
1474 changer drive number and system device name - and depending on the way the
1475 drives are hooked up to scsi busses, they may not be linearly numbered
1476 from an offset point either.something like
1478 Autochanger drives = 2
1479 Autochanger drive 0 = /dev/nst1
1480 Autochanger drive 1 = /dev/nst2
1481 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1482 times, not just for multidrive changers. For a 1 drive changer, that's
1488 MTX's manpage (1.2.15):
1489 unload [<slotnum>] [ <drivenum> ]
1490 Unloads media from drive <drivenum> into slot
1491 <slotnum>. If <drivenum> is omitted, defaults to
1492 drive 0 (as do all commands). If <slotnum> is
1493 omitted, defaults to the slot that the drive was
1494 loaded from. Note that there's currently no way
1495 to say 'unload drive 1's media to the slot it
1496 came from', other than to explicitly use that
1497 slot number as the destination.AB

1535 Handling removable disks
1537 From: Karl Cunningham <karlc@keckec.com>
1539 My backups are only to hard disk these days, in removable bays. This is my
1540 idea of how a backup to hard disk would work more smoothly. Some of these
1541 things Bacula does already, but I mention them for completeness. If others
1542 have better ways to do this, I'd like to hear about it.
1544 1. Accommodate several disks, rotated similar to how tapes are. Identified
1545 by partition volume ID or perhaps by the name of a subdirectory.
1546 2. Abort & notify the admin if the wrong disk is in the bay.
1547 3. Write backups to different subdirectories for each machine to be backed
1549 4. Volumes (files) get created as needed in the proper subdirectory, one
1551 5. When a disk is recycled, remove or zero all old backup files. This is
1552 important as the disk being recycled may be close to full. This may be
1553 better done manually since the backup files for many machines may be
1554 scattered in many subdirectories.
1559 - Make sure that all do_prompt() calls in Dir check for
1560 -1 (error) and -2 (cancel) returns.
1561 - Fix foreach_jcr() to have free_jcr() inside next().
1562 jcr=jcr_walk_start();
1563 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1566 - A Volume taken from Scratch should take on the retention period
1568 - Correct doc for Maximum Changer Wait (and others) accepting only
1570 - Implement status that shows why a job is being held in reserve, or
1571 rather why none of the drives are suitable.
1572 - Implement a way to disable a drive (so you can use the second
1573 drive of an autochanger, and the first one will not be used or
1575 - Make sure Maximum Volumes is respected in Pools when adding
1576 Volumes (e.g. when pulling a Scratch volume).
1577 - Keep same dcr when switching device ...
1578 - Implement code that makes the Dir aware that a drive is an
1579 autochanger (so the user doesn't need to use the Autochanger = yes
1581 - Make catalog respect ACL.
1582 - Add recycle count to Media record.
1583 - Add initial write date to Media record.
1584 - Fix store_yesno to be store_bitmask.
