9 - Document cleaning up the spool files:
10 db, pid, state, bsr, mail, conmsg, spool

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.

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.

75 Next Pool = <override>
78 There should be no need for a Level (migration is always Full, since you
79 don't calculate differential/incremental differences for migration),
80 Storage should be determined by the volume types in the pool, and Client
81 is really a selection issue. Migration should always occur to the
82 NextPool defined in the pool definition. If no nextpool is defined, the
83 job should end with a reason of "no place to go". If Next Pool statement
84 is present, we override the check in the pool definition and use the
87 Here's how I'd define Migration Selection Types:
90 Client -- Migrate data from selected client only. Migration Selection
91 Pattern regexp provides pattern to select client names, eg ^FS00* makes
92 all client names starting with FS00 eligible for migration.
94 Jobname -- Migration all jobs matching name. Migration Selection Pattern
95 regexp provides pattern to select jobnames existing in pool.
97 Volume -- Migrate all data on specified volumes. Migration Selection
98 Pattern regexp provides selection criteria for volumes to be migrated.
99 Volumes must exist in pool to be eligible for migration.
103 LowestUtil -- Identify the volume in the pool with the least data on it
104 and empty it. No Migration Selection Pattern required.
106 OldestVol -- Identify the LRU volume with data written, and empty it. No
107 Migration Selection Pattern required.
109 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
110 (starting with most full volumes) until pool occupancy drops below
111 <lowmig>. Pool highmig and lowmig values are in pool definition, no
112 Migration Selection Pattern required.
116 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
117 Migration Selection Pattern contains SQL query to execute; should return
118 a list of 1 or more jobuids to migrate.
120 PoolResidence -- Migrate data sitting in pool for longer than
121 PoolResidence value in pool definition. Migration Selection Pattern

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

265 - Look at -D_FORTIFY_SOURCE=2
266 - Add Win32 FileSet definition somewhere

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

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

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

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

539 === From Carsten Menke <bootsy52@gmx.net>
541 Following is a list of what I think in the situations where I'm faced with,
542 could be a usefull enhancement to bacula, which I'm certain other users will
543 benefit from as well.
545 1. NextJob/NextJobs Directive within a Job Resource in the form of
546 NextJobs = job1,job2.
549 I currently solved the problem with running multiple jobs each after each
550 by setting the Max Wait Time for a job to 8 hours, and give
551 the jobs different Priorities. However, there scenarios where
552 1 Job is directly depending on another job, so if the former job fails,
553 the job after it needn't to be run
554 while maybe other jobs should run despite of that
557 A Backup Job and a Verify job, if the backup job fails there is no need to run
558 the verify job, as the backup job already failed. However, one may like
559 to backup the Catalog to disk despite of that the main backup job failed.
562 I see that this is related to the Event Handlers which are on the ToDo
563 list, also it is maybe a good idea to check for the return value and
564 execute different actions based on the return value
567 3. offline capability to bconsole
570 Currently I use a script which I execute within the last Job via the
571 RunAfterJob Directive, to release and eject the tape.
572 So I have to call bconsole "release=Storage-Name" and afterwards
573 mt -f /dev/nst0 eject to get the tape out.
575 If I have multiple Storage Devices, than these may not be /dev/nst0 and
576 I have to modify the script or call it with parameters etc.
577 This would actually not be needed, as everything is already defined
578 in bacula-sd.conf and if I can invoke bconsole with the
579 storage name via $1 in the script than I'm done and information is
582 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
586 For the reason mentioned in 3. to have the ability to call a
587 script with /scripts/foobar %s and in the script use $1
588 to pass the Storage Name to bconsole
590 5. Setting Volume State within a Job Resource
593 Instead of using "Maximum Volume Jobs" in the Pool Resource,
594 I would have the possibilty to define
595 in a Job Resource that after this certain job is run, the Volume State
596 should be set to "Volume State = Used", this give more flexibility (IMHO).
598 6. Localization of Bacula Messages
601 Unfortunatley many,many people I work with don't speak english very well.
602 So if at least the Reporting messages would be localized then they
603 would understand that they have to change the tape,etc. etc.
605 I volunteer to do the german translations, and if I can convince my wife also
606 french and Morre (western african language).
608 7. OK, this is evil, probably bound to security risks and maybe not possible
609 due to the design of bacula.
611 Implementation of Backtics ( `command` ) for shell comand execution to
612 the "Label Format" Directive.
616 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
617 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
618 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
619 the localized name for the day of the week appended to the
620 format string. Then I have the tape labeled automatically with weekday
621 name in the correct language.
623 - Yes, that is surely the case. I probably should turn those into Warning
624 errors. In addition, you just made me think that it might not be bad to
625 add an option to check the file size after backing up the file and
626 report if it changes. This would be done as an option because it would
629 Kern, good idea. If you do do that, mention in the output: file
630 shrunk, or file expanded, just to make it obvious to the user
631 (without having to the refer to file size), just how the file size
634 Would this option be for all file, or just one file? Or a fileset?
635 - Make output from status use html table tags for nicely
636 presenting in a browser.
637 - Can one write tapes faster with 8192 byte block sizes?
638 - Document security problems with the same password for everyone in
639 rpm and Win32 releases.
640 - Browse generations of files.
641 - I've seen an error when my catalog's File table fills up. I
642 then have to recreate the File table with a larger maximum row
643 size. Relevant information is at
644 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
645 "Installing and Configuring MySQL" chapter should talk a bit
646 about this potential problem, and recommend a solution.
647 - For Solaris must use POSIX awk.
648 - Want speed of writing to tape while despooling.
649 - Supported autochanger:
657 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
658 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
659 - Add regex from http://www.pcre.org to Bacula for Win32.
660 - Use only shell tools no make in CDROM package.
661 - Include within include does it work?
662 - Implement a Pool of type Cleaning?
663 - Implement VolReadTime and VolWriteTime in SD
664 - Modify Backing up Your Database to include a bootstrap file.
665 - Think about making certain database errors fatal.
666 - Look at correcting the time jump in the scheduler for daylight
667 savings time changes.
668 - Add a "real" timer to network connections.
669 - Promote to Full = Time period
670 - Check dates entered by user for correctness (month/day/... ranges)
671 - Compress restore Volume listing by date and first file.
672 - Look at patches/bacula_db.b2z postgresql that loops during restore.
674 - Perhaps add read/write programs and/or plugins to FileSets.
675 - How to handle backing up portables ...
676 - Add some sort of guaranteed Interval for upgrading jobs.
677 - Can we write the state file after every job terminates? On Win32
678 the system crashes and the state file is not updated.
681 Documentation to do: (any release a little bit at a time)
682 - Doc to do unmount before removing magazine.
683 - Alternative to static linking "ldd prog" save all binaries listed,
684 restore them and point LD_LIBRARY_PATH to them.
685 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
686 - Document query file format.
687 - Add more documentation for bsr files.
688 - Document problems with Verify and pruning.
689 - Document how to use multiple databases.
690 - VXA drives have a "cleaning required"
691 indicator, but Exabyte recommends preventive cleaning after every 75
694 In this context, it should be noted that Exabyte has a command-line
695 vxatool utility available for free download. (The current version is
696 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
697 test the drive, unload tapes, change drive settings, flash new firmware,
699 Of particular interest in this context is that vxatool <device> -i will
700 report, among other details, the time since last cleaning in tape motion
701 minutes. This information can be retrieved (and settings changed, for
702 that matter) through the generic-SCSI device even when Bacula has the
703 regular tape device locked. (Needless to say, I don't recommend
704 changing tape settings while a job is running.)
705 - Lookup HP cleaning recommendations.
706 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
707 - Document doing table repair
710 ===================================
711 - Add macro expansions in JobDefs.
712 Run Before Job = "SomeFile %{Level} %{Client}"
713 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
714 - Use non-blocking network I/O but if no data is available, use
716 - Use gather write() for network I/O.
717 - Autorestart on crash.
718 - Add bandwidth limiting.
719 - Add acks every once and a while from the SD to keep
720 the line from timing out.
721 - When an error in input occurs and conio beeps, you can back
722 up through the prompt.
723 - Detect fixed tape block mode during positioning by looking at
724 block numbers in btape "test". Possibly adjust in Bacula.
725 - Fix list volumes to output volume retention in some other
726 units, perhaps via a directive.
727 - If opening a tape in read/write mode fails attempt to open
728 it in read-only mode, and mark the tape for read only.
729 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
730 with multiple priorities.
731 - If you use restore replace=never, the directory attributes for
732 non-existent directories will not be restored properly.
734 - see lzma401.zip in others directory for new compression
736 - Minimal autochanger handling in Bacula and in btape.
737 - Look into how tar does not save sockets and the possiblity of
738 not saving them in Bacula (Martin Simmons reported this).
739 - Fix restore jobs so that multiple jobs can run if they
740 are not using the same tape(s).
741 - Allow the user to select JobType for manual pruning/purging.
742 - bscan does not put first of two volumes back with all info in
744 - Implement the FreeBSD nodump flag in chflags.
745 - Figure out how to make named console messages go only to that
746 console and to the non-restricted console (new console class?).
747 - Make restricted console prompt for password if *ask* is set or
748 perhaps if password is undefined.
749 - Implement "from ISO-date/time every x hours/days/weeks/months" in
752 ==== from Marc Schoechlin
753 - the help-command should be more verbose
754 (it should explain the paramters of the different
756 -> its time-comsuming to consult the manual anytime
757 you need a special parameter
758 -> maybe its more easy to maintain this, if the
759 descriptions of that commands are outsourced to
761 - the cd-command should allow complete paths
762 i.e. cd /foo/bar/foo/bar
763 -> if a customer mails me the path to a certain file,
764 its faster to enter the specified directory
765 - if the password is not configured in bconsole.conf
766 you should be asked for it.
767 -> sometimes you like to do restore on a customer-machine
768 which shouldnt know the password for bacula.
769 -> adding the password to the file favours admins
770 to forget to remove the password after usage
772 the protection of that file is less important
773 - long-listed-output of commands should be scrollable
774 like the unix more/less-command does
775 -> if someone runs 200 and more machines, the lists could
776 be a little long and complex
777 - command-output should be shown column by column
778 to reduce scrolling and to increase clarity
780 - lsmark should list the selected files with full
782 - wildcards for selecting and file and directories would be nice
783 - any actions should be interuptable with STRG+C
784 - command-expansion would be pretty cool
786 - When the replace Never option is set, new directory permissions
787 are not restored. See bug 213. To fix this requires creating a
788 list of newly restored directories so that those directory
789 permissions *can* be restored.
790 - Compaction of Disk space by "migrating" Volumes that have pruned
791 Jobs (what criteria? size, #jobs, time).
792 - Add prune all command
793 - Document fact that purge can destroy a part of a restore by purging
794 one volume while others remain valid -- perhaps mark Jobs.
795 - Add multiple-media-types.txt
796 - look at mxt-changer.html
797 - Make ? do a help command (no return needed).
798 - Implement restore directory.
799 - Document streams and how to implement them.
800 - Try not to re-backup a file if a new hard link is added.
801 - Add feature to backup hard links only, but not the data.
802 - Fix stream handling to be simpler.
803 - Add Priority and Bootstrap to Run a Job.
804 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
806 - Remove View FileSet button from Run a Job dialog.
807 - Handle prompt for restore job at end of Restore command.
808 - Add display of total selected files to Restore window.
809 - Add tree pane to left of window.
810 - Add progress meter.
811 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
812 - Document writing to a CD/DVD with Bacula.
813 - Add a "base" package to the window installer for pthreadsVCE.dll
814 which is needed by all packages.
815 - Add message to user to check for fixed block size when the forward
816 space test fails in btape.
817 - When unmarking a directory check if all files below are unmarked and
818 then remove the + flag -- in the restore tree.
819 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
820 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
821 - Revisit the question of multiple Volumes (disk) on a single device.
822 - Add a block copy option to bcopy.
823 - Investigate adding Mac Resource Forks.
824 - Finish work on Gnome restore GUI.
825 - Fix "llist jobid=xx" where no fileset or client exists.
826 - For each job type (Admin, Restore, ...) require only the really necessary
827 fields.- Pass Director resource name as an option to the Console.
828 - Add a "batch" mode to the Console (no unsolicited queries, ...).
829 - Add a .list all files in the restore tree (probably also a list all files)
830 Do both a long and short form.
831 - Allow browsing the catalog to see all versions of a file (with
832 stat data on each file).
833 - Restore attributes of directory if replace=never set but directory
835 - Use SHA1 on authentication if possible.
836 - See comtest-xxx.zip for Windows code to talk to USB.
837 - Add John's appended files:
838 Appended = { /files/server/logs/http/*log }
839 and such files would be treated as follows.On a FULL backup, they would
840 be backed up like any other file.On an INCREMENTAL backup, where a
841 previous INCREMENTAL or FULL was already in thecatalogue and the length
842 of the file wasgreater than the length of the last backup, only thedata
843 added since the last backup will be dumped.On an INCREMENTAL backup, if
844 the length of the file is less than thelength of the file with the same
845 name last backed up, the completefile is dumped.On Windows systems, with
846 creation date of files, we can be evensmarter about this and not count
847 entirely upon the length.On a restore, the full and all incrementals
848 since it will beapplied in sequence to restore the file.
849 - Check new HAVE_WIN32 open bits.
850 - Check if the tape has moved before writing.
851 - Handling removable disks -- see below:
852 - Keep track of tape use time, and report when cleaning is necessary.
853 - Add FromClient and ToClient keywords on restore command (or
854 BackupClient RestoreClient).
855 - Implement a JobSet, which groups any number of jobs. If the
856 JobSet is started, all the jobs are started together.
857 Allow Pool, Level, and Schedule overrides.
858 - Enhance cancel to timeout BSOCK packets after a specific delay.
859 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
860 ua_status.!!! Thanks to Alan Brown for this tip.
861 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
862 correctly for multiple simultaneous jobs.
863 - Correct code so that FileSet MD5 is calculated for < and | filename
865 - Implement the Media record flag that indicates that the Volume does disk
867 - Implement VolAddr, which is used when Volume is addressed like a disk,
868 and form it from VolFile and VolBlock.
869 - Make multiple restore jobs for multiple media types specifying
870 the proper storage type.
871 - Fix fast block rejection (stored/read_record.c:118). It passes a null
872 pointer (rec) to try_repositioning().
873 - Look at extracting Win data from BackupRead.
874 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
875 which would take precidence over the Catalog "JobRetention".
876 - Implement Label Format in Add and Label console commands.
877 - Possibly up network buffers to 65K. Put on variable.
878 - Put email tape request delays on one or more variables. User wants
879 to cancel the job after a certain time interval. Maximum Mount Wait?
880 - Job, Client, Device, Pool, or Volume?
881 Is it possible to make this a directive which is *optional* in multiple
882 resources, like Level? If so, I think I'd make it an optional directive
883 in Job, Client, and Pool, with precedence such that Job overrides Client
884 which in turn overrides Pool.
886 - New Storage specifications:
887 - Want to write to multiple storage devices simultaneously
888 - Want to write to multiple storage devices sequentially (in one job)
889 - Want to read/write simultaneously
890 - Key is MediaType -- it must match
892 Passed to SD as a sort of BSR record called Storage Specification
896 MediaType -> Next MediaType
898 Device -> Next Device
900 Allow multiple Storage specifications
908 Allow Multiple Pool specifications (note, Pool currently
910 Allow Multiple MediaType specifications in Dir conf
911 Allow Multiple Device specifications in Dir conf
912 Perhaps keep this in a single SSR
913 Tie a Volume to a specific device by using a MediaType that
914 is contained in only one device.
915 In SD allow Device to have Multiple MediaTypes
917 - Ideas from Jerry Scharf:
918 First let's point out some big pluses that bacula has for this
920 more importantly it's active. Thank you so much for that
921 even more important, it's not flaky
922 it has an open access catalog, opening many possibilities
923 it's pushing toward heterogeneous systems capability
925 Macintosh file client
926 macs are an interesting niche, but I fear a server is a rathole
927 working bare iron recovery for windows
928 the option for inc/diff backups not reset on fileset revision
929 a) use both change and inode update time against base time
930 b) do the full catalog check (expensive but accurate)
931 sizing guide (how much system is needed to back up N systems/files)
932 consultants on using bacula in building a disaster recovery system
934 or how to get at fancy things that one could do with bacula
935 logwatch code for bacula logs (or similar)
936 linux distro inclusion of bacula (brings good and bad, but necessary)
937 win2k/XP server capability (icky but you asked)
938 support for Oracle database ??
940 - Look at adding SQL server and Exchange support for Windows.
941 - Make dev->file and dev->block_num signed integers so that -1 can
942 be an invalid value which happens with BSR.
943 - Create VolAddr for disk files in place of VolFile and VolBlock. This
944 is needed to properly specify ranges.
945 - Add progress of files/bytes to SD and FD.
946 - Print warning message if FileId > 4 billion
947 - do a "messages" before the first prompt in Console
948 - Client does not show busy during Estimate command.
949 - Implement Console mtx commands.
950 - Implement a Mount Command and an Unmount Command where
951 the users could specify a system command to be performed
952 to do the mount, after which Bacula could attempt to
953 read the device. This is for Removeable media such as a CDROM.
954 - Most likely, this mount command would be invoked explicitly
955 by the user using the current Console "mount" and "unmount"
956 commands -- the Storage Daemon would do the right thing
957 depending on the exact nature of the device.
958 - As with tape drives, when Bacula wanted a new removable
959 disk mounted, it would unmount the old one, and send a message
960 to the user, who would then use "mount" as described above
961 once he had actually inserted the disk.
962 - Implement dump/print label to UA
963 - Spool to disk only when the tape is full, then when a tape is hung move
965 - bextract is sending everything to the log file ****FIXME****
966 - Allow multiple Storage specifications (or multiple names on
967 a single Storage specification) in the Job record. Thus a job
968 can be backed up to a number of storage devices.
969 - Implement some way for the File daemon to contact the Director
970 to start a job or pass its DHCP obtained IP number.
971 - Implement a query tape prompt/replace feature for a console
972 - Copy console @ code to gnome2-console
973 - Make AES the only encryption algorithm see
974 http://csrc.nist.gov/CryptoToolkit/aes/). It's
975 an officially adopted standard, has survived peer
976 review, and provides keys up to 256 bits.
977 - Take a careful look at SetACL http://setacl.sourceforge.net
978 - Make tree walk routines like cd, ls, ... more user friendly
979 by handling spaces better.
980 - Make sure that Bacula rechecks the tape after the 20 min wait.
981 - Set IO_NOWAIT on Bacula TCP/IP packets.
982 - Try doing a raw partition backup and restore by mounting a
985 Yes, it would allow to highly automatic the request for new tapes. If a
986 tape is empty, bacula reads the barcodes (native or simulated), and if
987 an unused tape is found, it runs the label command with all the
988 necessary parameters.
990 By the way can bacula automatically "move" an empty/purged volume say
991 in the "short" pool to the "long" pool if this pool runs out of volume
993 - What to do about "list files job=xxx".
994 - Get and test MySQL 4.0
995 - Look at how fuser works and /proc/PID/fd that is how Nic found the
996 file descriptor leak in Bacula.
997 - Implement WrapCounters in Counters.
998 - Add heartbeat from FD to SD if hb interval expires.
999 - Can we dynamically change FileSets?
1000 - If pool specified to label command and Label Format is specified,
1001 automatically generate the Volume name.
1002 - Why can't SQL do the filename sort for restore?
1003 - Add ExhautiveRestoreSearch
1004 - Look at the possibility of loading only the necessary
1005 data into the restore tree (i.e. do it one directory at a
1006 time as the user walks through the tree).
1007 - Possibly use the hash code if the user selects all for a restore command.
1008 - Fix "restore all" to bypass building the tree.
1009 - Prohibit backing up archive device (findlib/find_one.c:128)
1010 - Implement Release Device in the Job resource to unmount a drive.
1011 - Implement Acquire Device in the Job resource to mount a drive,
1012 be sure this works with admin jobs so that the user can get
1013 prompted to insert the correct tape. Possibly some way to say to
1014 run the job but don't save the files.
1015 - Make things like list where a file is saved case independent for
1018 - Use autochanger to handle multiple devices.
1019 - On Windows with very long path names, it may be impossible to create
1020 a file (and thus restore it) because the total length is too long.
1021 We must cd into the directory then create the file without the
1023 - Implement a Recycle command
1024 - Test a second language e.g. french.
1025 - Start working on Base jobs.
1026 - Implement UnsavedFiles DB record.
1027 - From Phil Stracchino:
1028 It would probably be a per-client option, and would be called
1029 something like, say, "Automatically purge obsoleted jobs". What it
1030 would do is, when you successfully complete a Differential backup of a
1031 client, it would automatically purge all Incremental backups for that
1032 client that are rendered redundant by that Differential. Likewise,
1033 when a Full backup on a client completed, it would automatically purge
1034 all Differential and Incremental jobs obsoleted by that Full backup.
1035 This would let people minimize the number of tapes they're keeping on
1036 hand without having to master the art of retention times.
1037 - When doing a Backup send all attributes back to the Director, who
1038 would then figure out what files have been deleted.
1039 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1040 explicit permission to do so. It should also mark the tape in error
1041 if there is an error.
1042 - Cancel waiting for Client connect in SD if FD goes away.
1044 - Implement timeout in response() when it should come quickly.
1045 - Implement a Slot priority (loaded/not loaded).
1046 - Implement "vacation" Incremental only saves.
1047 - Implement create "FileSet"?
1048 - Add prefixlinks to where or not where absolute links to FD.
1049 - Issue message to mount a new tape before the rewind.
1050 - Simplified client job initiation for portables.
1051 - If SD cannot open a drive, make it periodically retry.
1052 - Add more of the config info to the tape label.
1054 - If tape is marked read-only, then try opening it read-only rather than
1055 failing, and remember that it cannot be written.
1056 - Refine SD waiting output:
1057 Device is being positioned
1058 > Device is being positioned for append
1059 > Device is being positioned to file x
1061 - Figure out some way to estimate output size and to avoid splitting
1062 a backup across two Volumes -- this could be useful for writing CDROMs
1063 where you really prefer not to have it split -- not serious.
1064 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1065 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1066 actual data on the Volume and compare it.
1067 - Implement Bacula plugins -- design API
1068 - Make bcopy read through bad tape records.
1069 - Program files (i.e. execute a program to read/write files).
1070 Pass read date of last backup, size of file last time.
1071 - Add Signature type to File DB record.
1072 - CD into subdirectory when open()ing files for backup to
1073 speed up things. Test with testfind().
1074 - Priority job to go to top of list.
1075 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1076 - Implement some way for the Console to dynamically create a job.
1077 - Solaris -I on tar for include list
1078 - Need a verbose mode in restore, perhaps to bsr.
1079 - bscan without -v is too quiet -- perhaps show jobs.
1080 - Add code to reject whole blocks if not wanted on restore.
1081 - Check if we can increase Bacula FD priorty in Win2000
1082 - Make sure the MaxVolFiles is fully implemented in SD
1083 - Check if both CatalogFiles and UseCatalog are set to SD.
1084 - Possibly add email to Watchdog if drive is unmounted too
1085 long and a job is waiting on the drive.
1086 - After unmount, if restore job started, ask to mount.
1087 - Add UA rc and history files.
1088 - put termcap (used by console) in ./configure and
1089 allow -with-termcap-dir.
1090 - Fix Autoprune for Volumes to respect need for full save.
1091 - Compare tape to Client files (attributes, or attributes and data)
1092 - Make all database Ids 64 bit.
1093 - Allow console commands to detach or run in background.
1094 - Fix status delay on storage daemon during rewind.
1095 - Add SD message variables to control operator wait time
1096 - Maximum Operator Wait
1097 - Minimum Message Interval
1098 - Maximum Message Interval
1099 - Send Operator message when cannot read tape label.
1100 - Verify level=Volume (scan only), level=Data (compare of data to file).
1101 Verify level=Catalog, level=InitCatalog
1103 - Add keyword search to show command in Console.
1104 - Events : tape has more than xxx bytes.
1105 - Complete code in Bacula Resources -- this will permit
1106 reading a new config file at any time.
1107 - Handle ctl-c in Console
1108 - Implement script driven addition of File daemon to config files.
1109 - Think about how to make Bacula work better with File (non-tape) archives.
1110 - Write Unix emulator for Windows.
1111 - Put memory utilization in Status output of each daemon
1112 if full status requested or if some level of debug on.
1113 - Make database type selectable by .conf files i.e. at runtime
1114 - Set flag for uname -a. Add to Volume label.
1115 - Restore files modified after date
1116 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1117 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1118 - Timout a job or terminate if link goes down, or reopen link and query.
1119 - Concept of precious tapes (cannot be reused).
1120 - Make bcopy copy with a single tape drive.
1121 - Permit changing ownership during restore.
1124 > My suggestion: Add a feature on the systray menu-icon menu to request
1125 > an immediate backup now. This would be useful for laptop users who may
1126 > not be on the network when the regular scheduled backup is run.

1135 - Autolabel should be specified by DIR instead of SD.
1137 - Add media capacity
1138 - AutoScan (check checksum of tape)
1139 - Format command = "format /dev/nst0"
1143 - Seek resolution (usually corresponds to buffer size)
1144 - EODErrorCode=ENOSPC or code
1145 - Partial Read error code
1146 - Partial write error code
1147 - Nonformatted read error
1148 - Nonformatted write error
1149 - WriteProtected error
1153 - IgnoreCloseErrors=yes
1163 - FD sends unsaved file list to Director at end of job (see
1165 - File daemon should build list of files skipped, and then
1166 at end of save retry and report any errors.
1167 - Write a Storage daemon that uses pipes and
1168 standard Unix programs to write to the tape.
1170 - Need something that monitors the JCR queue and
1171 times out jobs by asking the deamons where they are.
1172 - Enhance Jmsg code to permit buffering and saving to disk.
1173 - device driver = "xxxx" for drives.
1174 - Verify from Volume
1175 - Ensure that /dev/null works
1176 - Need report class for messages. Perhaps
1177 report resource where report=group of messages
1178 - enhance scan_attrib and rename scan_jobtype, and
1179 fill in code for "since" option
1180 - Director needs a time after which the report status is sent
1181 anyway -- or better yet, a retry time for the job.
1182 - Don't reschedule a job if previous incarnation is still running.
1183 - Some way to automatically backup everything is needed????
1184 - Need a structure for pending actions:
1186 - termination status (part of buffered msgs?)
1188 Read, Write, Clean, Delete
1189 - Login to Bacula; Bacula users with different permissions:
1190 owner, group, user, quotas
1191 - Store info on each file system type (probably in the job header on tape.
1192 This could be the output of df; or perhaps some sort of /etc/mtab record.

1197 Subject: RE: [Bacula-users] future large programming jobs
1198 Date: Thu, 26 Feb 2004 11:34:54 -0600
1200 I noticed the subject thread and thought I would offer the following
1201 merely as sources of ideas, i.e. something to think about, not even as
1202 strong as a request. In my former life (before retiring) I often
1203 dealt with backups and storage management issues/products as a
1204 developer and as a consultant. I am currently migrating my personal
1205 network from amanda to bacula specifically because of the ability to
1206 cross media boundaries during storing backups.
1207 Are you familiar with the commercial product called ADSM (I think IBM
1208 now sells it under the Tivoli label)? It has a couple of interesting
1209 ideas that may apply to the following topics.
1211 1. Migration: Consider that when you need to restore a system, there
1212 may be pressure to hurry. If all the information for a single client
1213 can eventually end up on the same media (and in chronological order),
1214 the restore is facillitated by not having to search past information
1215 from other clients. ADSM has the concept of "client affinity" that
1216 may be associated with it's storage pools. It seems to me that this
1217 concept (as an optional feature) might fit in your architecture for
1220 ADSM also has the concept of defining one or more storage pools as
1221 "copy pools" (almost mirrors, but only in the sense of contents).
1222 These pools provide the ability to have duplicte data stored both
1223 onsite and offsite. The copy process can be scheduled to be handled
1224 by their storage manager during periods when there is no backup
1225 activity. Again, the migration process might be a place to consider
1226 implementing something like this.
1229 > It strikes me that it would be very nice to be able to do things
1231 > have the Job(s) backing up the machines run, and once they have all
1232 > completed, start a migration job to copy the data from disks Volumes

1237 > mechanism described below would probably make it very easy.
1239 This is the goal. In the first step (before events), you simply
1241 the Migration to tape later.
1243 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1244 the database. Once a file (unique by path and metadata such as dates,
1245 size, ownership, etc.) is in a copy pool, no more copies are made. In
1246 other words, when you start ADSM, it begins like your concept of a
1247 base job. After that it is in the "incremental" mode. You can
1248 configure the number of "generations" of files to be retained, plus a
1249 retention date after which even old generations are purged. The
1250 database tracks the contents of media and projects the percentage of
1251 each volume that is valid. When the valid content of a volume drops
1252 below a configured percentage, the valid data are migrated to another
1253 volume and the old volume is marked as empty. Note, this requires
1254 ADSM to have an idea of the contents of a client, i.e. marking the
1255 database when an existing file was deleted, but this would solve your
1256 issue of restoring a client without restoring deleted files.
1258 This is pretty far from what bacula now does, but if you are going to
1259 rip things up for Base jobs,.....
1260 Also, the benefits of this are huge for very large shops, especially
1261 with media robots, but are a pain for shops with manual media
1265 > Base jobs sound pretty useful, but I'm not dying for them.
1267 Nobody is dying for them, but when you see what it does, you will die
1270 3. Restoring deleted files: Since I think my comments in (2) above
1271 have low probability of implementation, I'll also suggest that you
1272 could approach the issue of deleted files by a mechanism of having the
1273 fd report to the dir, a list of all files on the client for every
1274 backup job. The dir could note in the database entry for each file
1275 the date that the file was seen. Then if a restore as of date X takes
1276 place, only files that exist from before X until after X would be
1277 restored. Probably the major cost here is the extra date container in
1278 each row of the files table.
1280 Thanks for "listening". I hope some of this helps. If you want to
1281 contact me, please send me an email - I read some but not all of the
1282 mailing list traffic and might miss a reply there.
1284 Please accept my compliments for bacula. It is doing a great job for
1285 me!! I sympathize with you in the need to wrestle with excelence in
1286 execution vs. excelence in feature inclusion.
1291 ==============================
1294 - Design at hierarchial storage for Bacula. Migration and Clone.
1295 - Implement FSM (File System Modules).
1296 - Audit M_ error codes to ensure they are correct and consistent.
1297 - Add variable break characters to lex analyzer.
1298 Either a bit mask or a string of chars so that
1299 the caller can change the break characters.
1300 - Make a single T_BREAK to replace T_COMMA, etc.
1301 - Ensure that File daemon and Storage daemon can
1302 continue a save if the Director goes down (this
1303 is NOT currently the case). Must detect socket error,
1304 buffer messages for later.
1305 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1306 - Add ability to backup to two Storage devices (two SD sessions) at
1307 the same time -- e.g. onsite, offsite.
1308 - Add the ability to consolidate old backup sets (basically do a restore
1309 to tape and appropriately update the catalog). Compress Volume sets.
1310 Might need to spool via file is only one drive is available.
1311 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1312 someway to do so with every volume that has less than x% valid
1316 Migration: Move a backup from one Volume to another
1317 Clone: Copy a backup -- two Volumes
1319 Bacula Migration is based on Jobs (apparently Networker is file by file).

1330 ======================================================
1332 It is somewhat like a Full save becomes an incremental since
1333 the Base job (or jobs) plus other non-base files.
1335 - A Base backup is same as Full backup, just different type.
1336 - New BaseFiles table that contains:
1338 BaseJobId - Base JobId referenced for this FileId (needed ???)
1339 JobId - JobId currently running
1340 FileId - File not backed up, exists in Base Job
1341 FileIndex - FileIndex from Base Job.
1342 i.e. for each base file that exists but is not saved because
1343 it has not changed, the File daemon sends the JobId, BaseId,
1344 FileId, FileIndex back to the Director who creates the DB entry.
1345 - To initiate a Base save, the Director sends the FD
1346 the FileId, and full filename for each file in the Base.
1347 - When the FD finds a Base file, he requests the Director to
1348 send him the full File entry (stat packet plus MD5), or
1349 conversely, the FD sends it to the Director and the Director
1350 says yes or no. This can be quite rapid if the FileId is kept
1351 by the FD for each Base Filename.
1352 - It is probably better to have the comparison done by the FD
1353 despite the fact that the File entry must be sent across the
1355 - An alternative would be to send the FD the whole File entry
1356 from the start. The disadvantage is that it requires a lot of
1357 space. The advantage is that it requires less communications
1359 - The Job record must be updated to indicate that one or more
1361 - At end of Job, FD returns:
1362 1. Count of base files/bytes not written to tape (i.e. matches)
1363 2. Count of base file that were saved i.e. had changed.
1364 - No tape record would be written for a Base file that matches, in the
1365 same way that no tape record is written for Incremental jobs where
1366 the file is not saved because it is unchanged.
1367 - On a restore, all the Base file records must explicitly be
1368 found from the BaseFile tape. I.e. for each Full save that is marked
1369 to have one or more Base Jobs, search the BaseFile for all occurrences
1371 - An optimization might be to make the BaseFile have:
1377 This would avoid the need to explicitly fetch each File record for
1378 the Base job. The Base Job record will be fetched to get the
1379 VolSessionId and VolSessionTime.
1380 =========================================================
1383 ==========================================================
1385 For each Incremental job that is run, there may be files that
1386 were found but not saved because they were locked (this applies
1387 only to Windows). Such a system could send back to the Director
1388 a list of Unsaved files.
1390 - New UnSavedFiles table that contains:
1394 - Then in the next Incremental job, the list of Unsaved Files will be
1395 feed to the FD, who will ensure that they are explicitly chosen even
1396 if standard date/time check would not have selected them.

1438 (just to verify it remembers where it came from, however it can be

1441 There needs to be a table of drive # to devices somewhere - If there are
1442 multiple changers or drives there may not be a 1:1 correspondance between
1443 changer drive number and system device name - and depending on the way the
1444 drives are hooked up to scsi busses, they may not be linearly numbered
1445 from an offset point either.something like
1447 Autochanger drives = 2
1448 Autochanger drive 0 = /dev/nst1
1449 Autochanger drive 1 = /dev/nst2
1450 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1451 times, not just for multidrive changers. For a 1 drive changer, that's
1457 MTX's manpage (1.2.15):
1458 unload [<slotnum>] [ <drivenum> ]
1459 Unloads media from drive <drivenum> into slot
1460 <slotnum>. If <drivenum> is omitted, defaults to
1461 drive 0 (as do all commands). If <slotnum> is
1462 omitted, defaults to the slot that the drive was
1463 loaded from. Note that there's currently no way
1464 to say 'unload drive 1's media to the slot it
1465 came from', other than to explicitly use that
1466 slot number as the destination.AB

1504 Handling removable disks
1506 From: Karl Cunningham <karlc@keckec.com>
1508 My backups are only to hard disk these days, in removable bays. This is my
1509 idea of how a backup to hard disk would work more smoothly. Some of these
1510 things Bacula does already, but I mention them for completeness. If others
1511 have better ways to do this, I'd like to hear about it.
1513 1. Accommodate several disks, rotated similar to how tapes are. Identified
1514 by partition volume ID or perhaps by the name of a subdirectory.
1515 2. Abort & notify the admin if the wrong disk is in the bay.
1516 3. Write backups to different subdirectories for each machine to be backed
1518 4. Volumes (files) get created as needed in the proper subdirectory, one
1520 5. When a disk is recycled, remove or zero all old backup files. This is
1521 important as the disk being recycled may be close to full. This may be
1522 better done manually since the backup files for many machines may be
1523 scattered in many subdirectories.
1528 - Make sure that all do_prompt() calls in Dir check for
1529 -1 (error) and -2 (cancel) returns.
1530 - Fix foreach_jcr() to have free_jcr() inside next().
1531 jcr=jcr_walk_start();
1532 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1535 - A Volume taken from Scratch should take on the retention period
1537 - Correct doc for Maximum Changer Wait (and others) accepting only
1539 - Implement status that shows why a job is being held in reserve, or
1540 rather why none of the drives are suitable.
1541 - Implement a way to disable a drive (so you can use the second
1542 drive of an autochanger, and the first one will not be used or
1544 - Make sure Maximum Volumes is respected in Pools when adding
1545 Volumes (e.g. when pulling a Scratch volume).
1546 - Keep same dcr when switching device ...
1547 - Implement code that makes the Dir aware that a drive is an
1548 autochanger (so the user doesn't need to use the Autochanger = yes
1550 - Make catalog respect ACL.
1551 - Add recycle count to Media record.
1552 - Add initial write date to Media record.
1553 - Fix store_yesno to be store_bitmask.
