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 - Make authentication failures single threaded.
27 - Make base64.c (bin_to_base64) take a buffer length
28 argument to avoid overruns.
29 - Fix catreq.c digestbuf at line 411 in src/dird/catreq.c
30 and verify that other buffers cannot overrun.
31 - Implement VolumeState as discussed with Arno.
33 - Document techniques for restoring large numbers of files.
34 - Document setting my.cnf to big file usage.
35 - Add example of proper index output to doc.
37 - Fix re-read of last block to check if job has actually written
38 a block, and check if block was written by a different job
39 (i.e. multiple simultaneous jobs writing).
40 - JobStatus and Termination codes.
41 - Some users claim that they must do two prune commands to get a
42 Volume marked as purged.
43 - Print warning message if LANG environment variable does not specify

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

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

219 - Add VolumeState (enable, disable, archive)
220 - Add VolumeLock to prevent all but lock holder (SD) from updating
221 the Volume data (with the exception of VolumeState).
222 - The btape fill command does not seem to use the Autochanger
223 - Make Windows installer default to system disk drive.
224 - Look at using ioctl(FIOBMAP, ...) on Linux, and
225 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
226 Win32 for sparse files.

242 and write the same device.
243 - Queue warning/error messages during restore so that they
244 are reported at the end of the report rather than being
245 hidden in the file listing ...
246 - Look at -D_FORTIFY_SOURCE=2
247 - Add Win32 FileSet definition somewhere

255 block cannot be read, skip to the next block, and try again. If
256 that fails, skip to the next file and try again, ...

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

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

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

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

520 === From Carsten Menke <bootsy52@gmx.net>
522 Following is a list of what I think in the situations where I'm faced with,
523 could be a usefull enhancement to bacula, which I'm certain other users will
524 benefit from as well.
526 1. NextJob/NextJobs Directive within a Job Resource in the form of
527 NextJobs = job1,job2.
530 I currently solved the problem with running multiple jobs each after each
531 by setting the Max Wait Time for a job to 8 hours, and give
532 the jobs different Priorities. However, there scenarios where
533 1 Job is directly depending on another job, so if the former job fails,
534 the job after it needn't to be run
535 while maybe other jobs should run despite of that
538 A Backup Job and a Verify job, if the backup job fails there is no need to run
539 the verify job, as the backup job already failed. However, one may like
540 to backup the Catalog to disk despite of that the main backup job failed.
543 I see that this is related to the Event Handlers which are on the ToDo
544 list, also it is maybe a good idea to check for the return value and
545 execute different actions based on the return value
548 3. offline capability to bconsole
551 Currently I use a script which I execute within the last Job via the
552 RunAfterJob Directive, to release and eject the tape.
553 So I have to call bconsole "release=Storage-Name" and afterwards
554 mt -f /dev/nst0 eject to get the tape out.
556 If I have multiple Storage Devices, than these may not be /dev/nst0 and
557 I have to modify the script or call it with parameters etc.
558 This would actually not be needed, as everything is already defined
559 in bacula-sd.conf and if I can invoke bconsole with the
560 storage name via $1 in the script than I'm done and information is
563 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
567 For the reason mentioned in 3. to have the ability to call a
568 script with /scripts/foobar %s and in the script use $1
569 to pass the Storage Name to bconsole
571 5. Setting Volume State within a Job Resource
574 Instead of using "Maximum Volume Jobs" in the Pool Resource,
575 I would have the possibilty to define
576 in a Job Resource that after this certain job is run, the Volume State
577 should be set to "Volume State = Used", this give more flexibility (IMHO).
579 6. Localization of Bacula Messages
582 Unfortunatley many,many people I work with don't speak english very well.
583 So if at least the Reporting messages would be localized then they
584 would understand that they have to change the tape,etc. etc.
586 I volunteer to do the german translations, and if I can convince my wife also
587 french and Morre (western african language).
589 7. OK, this is evil, probably bound to security risks and maybe not possible
590 due to the design of bacula.
592 Implementation of Backtics ( `command` ) for shell comand execution to
593 the "Label Format" Directive.
597 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
598 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
599 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
600 the localized name for the day of the week appended to the
601 format string. Then I have the tape labeled automatically with weekday
602 name in the correct language.
604 - Yes, that is surely the case. I probably should turn those into Warning
605 errors. In addition, you just made me think that it might not be bad to
606 add an option to check the file size after backing up the file and
607 report if it changes. This would be done as an option because it would
610 Kern, good idea. If you do do that, mention in the output: file
611 shrunk, or file expanded, just to make it obvious to the user
612 (without having to the refer to file size), just how the file size
615 Would this option be for all file, or just one file? Or a fileset?
616 - Make output from status use html table tags for nicely
617 presenting in a browser.
618 - Can one write tapes faster with 8192 byte block sizes?
619 - Document security problems with the same password for everyone in
620 rpm and Win32 releases.
621 - Browse generations of files.
622 - I've seen an error when my catalog's File table fills up. I
623 then have to recreate the File table with a larger maximum row
624 size. Relevant information is at
625 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
626 "Installing and Configuring MySQL" chapter should talk a bit
627 about this potential problem, and recommend a solution.
628 - For Solaris must use POSIX awk.
629 - Want speed of writing to tape while despooling.
630 - Supported autochanger:
638 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
639 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
640 - Add regex from http://www.pcre.org to Bacula for Win32.
641 - Use only shell tools no make in CDROM package.
642 - Include within include does it work?
643 - Implement a Pool of type Cleaning?
644 - Implement VolReadTime and VolWriteTime in SD
645 - Modify Backing up Your Database to include a bootstrap file.
646 - Think about making certain database errors fatal.
647 - Look at correcting the time jump in the scheduler for daylight
648 savings time changes.
649 - Add a "real" timer to network connections.
650 - Promote to Full = Time period
651 - Check dates entered by user for correctness (month/day/... ranges)
652 - Compress restore Volume listing by date and first file.
653 - Look at patches/bacula_db.b2z postgresql that loops during restore.
655 - Perhaps add read/write programs and/or plugins to FileSets.
656 - How to handle backing up portables ...
657 - Add some sort of guaranteed Interval for upgrading jobs.
658 - Can we write the state file after every job terminates? On Win32
659 the system crashes and the state file is not updated.
662 Documentation to do: (any release a little bit at a time)
663 - Doc to do unmount before removing magazine.
664 - Alternative to static linking "ldd prog" save all binaries listed,
665 restore them and point LD_LIBRARY_PATH to them.
666 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
667 - Document query file format.
668 - Add more documentation for bsr files.
669 - Document problems with Verify and pruning.
670 - Document how to use multiple databases.
671 - VXA drives have a "cleaning required"
672 indicator, but Exabyte recommends preventive cleaning after every 75
675 In this context, it should be noted that Exabyte has a command-line
676 vxatool utility available for free download. (The current version is
677 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
678 test the drive, unload tapes, change drive settings, flash new firmware,
680 Of particular interest in this context is that vxatool <device> -i will
681 report, among other details, the time since last cleaning in tape motion
682 minutes. This information can be retrieved (and settings changed, for
683 that matter) through the generic-SCSI device even when Bacula has the
684 regular tape device locked. (Needless to say, I don't recommend
685 changing tape settings while a job is running.)
686 - Lookup HP cleaning recommendations.
687 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
688 - Document doing table repair
691 ===================================
692 - Add macro expansions in JobDefs.
693 Run Before Job = "SomeFile %{Level} %{Client}"
694 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
695 - Use non-blocking network I/O but if no data is available, use
697 - Use gather write() for network I/O.
698 - Autorestart on crash.
699 - Add bandwidth limiting.
700 - Add acks every once and a while from the SD to keep
701 the line from timing out.
702 - When an error in input occurs and conio beeps, you can back
703 up through the prompt.
704 - Detect fixed tape block mode during positioning by looking at
705 block numbers in btape "test". Possibly adjust in Bacula.
706 - Fix list volumes to output volume retention in some other
707 units, perhaps via a directive.
708 - If opening a tape in read/write mode fails attempt to open
709 it in read-only mode, and mark the tape for read only.
710 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
711 with multiple priorities.
712 - If you use restore replace=never, the directory attributes for
713 non-existent directories will not be restored properly.
715 - see lzma401.zip in others directory for new compression
717 - Minimal autochanger handling in Bacula and in btape.
718 - Look into how tar does not save sockets and the possiblity of
719 not saving them in Bacula (Martin Simmons reported this).
720 - Fix restore jobs so that multiple jobs can run if they
721 are not using the same tape(s).
722 - Allow the user to select JobType for manual pruning/purging.
723 - bscan does not put first of two volumes back with all info in
725 - Implement the FreeBSD nodump flag in chflags.
726 - Figure out how to make named console messages go only to that
727 console and to the non-restricted console (new console class?).
728 - Make restricted console prompt for password if *ask* is set or
729 perhaps if password is undefined.
730 - Implement "from ISO-date/time every x hours/days/weeks/months" in
733 ==== from Marc Schoechlin
734 - the help-command should be more verbose
735 (it should explain the paramters of the different
737 -> its time-comsuming to consult the manual anytime
738 you need a special parameter
739 -> maybe its more easy to maintain this, if the
740 descriptions of that commands are outsourced to
742 - the cd-command should allow complete paths
743 i.e. cd /foo/bar/foo/bar
744 -> if a customer mails me the path to a certain file,
745 its faster to enter the specified directory
746 - if the password is not configured in bconsole.conf
747 you should be asked for it.
748 -> sometimes you like to do restore on a customer-machine
749 which shouldnt know the password for bacula.
750 -> adding the password to the file favours admins
751 to forget to remove the password after usage
753 the protection of that file is less important
754 - long-listed-output of commands should be scrollable
755 like the unix more/less-command does
756 -> if someone runs 200 and more machines, the lists could
757 be a little long and complex
758 - command-output should be shown column by column
759 to reduce scrolling and to increase clarity
761 - lsmark should list the selected files with full
763 - wildcards for selecting and file and directories would be nice
764 - any actions should be interuptable with STRG+C
765 - command-expansion would be pretty cool
767 - When the replace Never option is set, new directory permissions
768 are not restored. See bug 213. To fix this requires creating a
769 list of newly restored directories so that those directory
770 permissions *can* be restored.
771 - Compaction of Disk space by "migrating" Volumes that have pruned
772 Jobs (what criteria? size, #jobs, time).
773 - Add prune all command
774 - Document fact that purge can destroy a part of a restore by purging
775 one volume while others remain valid -- perhaps mark Jobs.
776 - Add multiple-media-types.txt
777 - look at mxt-changer.html
778 - Make ? do a help command (no return needed).
779 - Implement restore directory.
780 - Document streams and how to implement them.
781 - Try not to re-backup a file if a new hard link is added.
782 - Add feature to backup hard links only, but not the data.
783 - Fix stream handling to be simpler.
784 - Add Priority and Bootstrap to Run a Job.
785 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
787 - Remove View FileSet button from Run a Job dialog.
788 - Handle prompt for restore job at end of Restore command.
789 - Add display of total selected files to Restore window.
790 - Add tree pane to left of window.
791 - Add progress meter.
792 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
793 - Document writing to a CD/DVD with Bacula.
794 - Add a "base" package to the window installer for pthreadsVCE.dll
795 which is needed by all packages.
796 - Add message to user to check for fixed block size when the forward
797 space test fails in btape.
798 - When unmarking a directory check if all files below are unmarked and
799 then remove the + flag -- in the restore tree.
800 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
801 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
802 - Revisit the question of multiple Volumes (disk) on a single device.
803 - Add a block copy option to bcopy.
804 - Investigate adding Mac Resource Forks.
805 - Finish work on Gnome restore GUI.
806 - Fix "llist jobid=xx" where no fileset or client exists.
807 - For each job type (Admin, Restore, ...) require only the really necessary
808 fields.- Pass Director resource name as an option to the Console.
809 - Add a "batch" mode to the Console (no unsolicited queries, ...).
810 - Add a .list all files in the restore tree (probably also a list all files)
811 Do both a long and short form.
812 - Allow browsing the catalog to see all versions of a file (with
813 stat data on each file).
814 - Restore attributes of directory if replace=never set but directory
816 - Use SHA1 on authentication if possible.
817 - See comtest-xxx.zip for Windows code to talk to USB.
818 - Add John's appended files:
819 Appended = { /files/server/logs/http/*log }
820 and such files would be treated as follows.On a FULL backup, they would
821 be backed up like any other file.On an INCREMENTAL backup, where a
822 previous INCREMENTAL or FULL was already in thecatalogue and the length
823 of the file wasgreater than the length of the last backup, only thedata
824 added since the last backup will be dumped.On an INCREMENTAL backup, if
825 the length of the file is less than thelength of the file with the same
826 name last backed up, the completefile is dumped.On Windows systems, with
827 creation date of files, we can be evensmarter about this and not count
828 entirely upon the length.On a restore, the full and all incrementals
829 since it will beapplied in sequence to restore the file.
830 - Check new HAVE_WIN32 open bits.
831 - Check if the tape has moved before writing.
832 - Handling removable disks -- see below:
833 - Keep track of tape use time, and report when cleaning is necessary.
834 - Add FromClient and ToClient keywords on restore command (or
835 BackupClient RestoreClient).
836 - Implement a JobSet, which groups any number of jobs. If the
837 JobSet is started, all the jobs are started together.
838 Allow Pool, Level, and Schedule overrides.
839 - Enhance cancel to timeout BSOCK packets after a specific delay.
840 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
841 ua_status.!!! Thanks to Alan Brown for this tip.
842 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
843 correctly for multiple simultaneous jobs.
844 - Correct code so that FileSet MD5 is calculated for < and | filename
846 - Implement the Media record flag that indicates that the Volume does disk
848 - Implement VolAddr, which is used when Volume is addressed like a disk,
849 and form it from VolFile and VolBlock.
850 - Make multiple restore jobs for multiple media types specifying
851 the proper storage type.
852 - Fix fast block rejection (stored/read_record.c:118). It passes a null
853 pointer (rec) to try_repositioning().
854 - Look at extracting Win data from BackupRead.
855 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
856 which would take precidence over the Catalog "JobRetention".
857 - Implement Label Format in Add and Label console commands.
858 - Possibly up network buffers to 65K. Put on variable.
859 - Put email tape request delays on one or more variables. User wants
860 to cancel the job after a certain time interval. Maximum Mount Wait?
861 - Job, Client, Device, Pool, or Volume?
862 Is it possible to make this a directive which is *optional* in multiple
863 resources, like Level? If so, I think I'd make it an optional directive
864 in Job, Client, and Pool, with precedence such that Job overrides Client
865 which in turn overrides Pool.
867 - New Storage specifications:
868 - Want to write to multiple storage devices simultaneously
869 - Want to write to multiple storage devices sequentially (in one job)
870 - Want to read/write simultaneously
871 - Key is MediaType -- it must match
873 Passed to SD as a sort of BSR record called Storage Specification
877 MediaType -> Next MediaType
879 Device -> Next Device
881 Allow multiple Storage specifications
889 Allow Multiple Pool specifications (note, Pool currently
891 Allow Multiple MediaType specifications in Dir conf
892 Allow Multiple Device specifications in Dir conf
893 Perhaps keep this in a single SSR
894 Tie a Volume to a specific device by using a MediaType that
895 is contained in only one device.
896 In SD allow Device to have Multiple MediaTypes
898 - Ideas from Jerry Scharf:
899 First let's point out some big pluses that bacula has for this
901 more importantly it's active. Thank you so much for that
902 even more important, it's not flaky
903 it has an open access catalog, opening many possibilities
904 it's pushing toward heterogeneous systems capability
906 Macintosh file client
907 macs are an interesting niche, but I fear a server is a rathole
908 working bare iron recovery for windows
909 the option for inc/diff backups not reset on fileset revision
910 a) use both change and inode update time against base time
911 b) do the full catalog check (expensive but accurate)
912 sizing guide (how much system is needed to back up N systems/files)
913 consultants on using bacula in building a disaster recovery system
915 or how to get at fancy things that one could do with bacula
916 logwatch code for bacula logs (or similar)
917 linux distro inclusion of bacula (brings good and bad, but necessary)
918 win2k/XP server capability (icky but you asked)
919 support for Oracle database ??
921 - Look at adding SQL server and Exchange support for Windows.
922 - Make dev->file and dev->block_num signed integers so that -1 can
923 be an invalid value which happens with BSR.
924 - Create VolAddr for disk files in place of VolFile and VolBlock. This
925 is needed to properly specify ranges.
926 - Add progress of files/bytes to SD and FD.
927 - Print warning message if FileId > 4 billion
928 - do a "messages" before the first prompt in Console
929 - Client does not show busy during Estimate command.
930 - Implement Console mtx commands.
931 - Implement a Mount Command and an Unmount Command where
932 the users could specify a system command to be performed
933 to do the mount, after which Bacula could attempt to
934 read the device. This is for Removeable media such as a CDROM.
935 - Most likely, this mount command would be invoked explicitly
936 by the user using the current Console "mount" and "unmount"
937 commands -- the Storage Daemon would do the right thing
938 depending on the exact nature of the device.
939 - As with tape drives, when Bacula wanted a new removable
940 disk mounted, it would unmount the old one, and send a message
941 to the user, who would then use "mount" as described above
942 once he had actually inserted the disk.
943 - Implement dump/print label to UA
944 - Spool to disk only when the tape is full, then when a tape is hung move
946 - bextract is sending everything to the log file ****FIXME****
947 - Allow multiple Storage specifications (or multiple names on
948 a single Storage specification) in the Job record. Thus a job
949 can be backed up to a number of storage devices.
950 - Implement some way for the File daemon to contact the Director
951 to start a job or pass its DHCP obtained IP number.
952 - Implement a query tape prompt/replace feature for a console
953 - Copy console @ code to gnome2-console
954 - Make AES the only encryption algorithm see
955 http://csrc.nist.gov/CryptoToolkit/aes/). It's
956 an officially adopted standard, has survived peer
957 review, and provides keys up to 256 bits.
958 - Take a careful look at SetACL http://setacl.sourceforge.net
959 - Make tree walk routines like cd, ls, ... more user friendly
960 by handling spaces better.
961 - Make sure that Bacula rechecks the tape after the 20 min wait.
962 - Set IO_NOWAIT on Bacula TCP/IP packets.
963 - Try doing a raw partition backup and restore by mounting a
966 Yes, it would allow to highly automatic the request for new tapes. If a
967 tape is empty, bacula reads the barcodes (native or simulated), and if
968 an unused tape is found, it runs the label command with all the
969 necessary parameters.
971 By the way can bacula automatically "move" an empty/purged volume say
972 in the "short" pool to the "long" pool if this pool runs out of volume
974 - What to do about "list files job=xxx".
975 - Get and test MySQL 4.0
976 - Look at how fuser works and /proc/PID/fd that is how Nic found the
977 file descriptor leak in Bacula.
978 - Implement WrapCounters in Counters.
979 - Add heartbeat from FD to SD if hb interval expires.
980 - Can we dynamically change FileSets?
981 - If pool specified to label command and Label Format is specified,
982 automatically generate the Volume name.
983 - Why can't SQL do the filename sort for restore?
984 - Add ExhautiveRestoreSearch
985 - Look at the possibility of loading only the necessary
986 data into the restore tree (i.e. do it one directory at a
987 time as the user walks through the tree).
988 - Possibly use the hash code if the user selects all for a restore command.
989 - Fix "restore all" to bypass building the tree.
990 - Prohibit backing up archive device (findlib/find_one.c:128)
991 - Implement Release Device in the Job resource to unmount a drive.
992 - Implement Acquire Device in the Job resource to mount a drive,
993 be sure this works with admin jobs so that the user can get
994 prompted to insert the correct tape. Possibly some way to say to
995 run the job but don't save the files.
996 - Make things like list where a file is saved case independent for
999 - Use autochanger to handle multiple devices.
1000 - On Windows with very long path names, it may be impossible to create
1001 a file (and thus restore it) because the total length is too long.
1002 We must cd into the directory then create the file without the
1004 - Implement a Recycle command
1005 - Test a second language e.g. french.
1006 - Start working on Base jobs.
1007 - Implement UnsavedFiles DB record.
1008 - From Phil Stracchino:
1009 It would probably be a per-client option, and would be called
1010 something like, say, "Automatically purge obsoleted jobs". What it
1011 would do is, when you successfully complete a Differential backup of a
1012 client, it would automatically purge all Incremental backups for that
1013 client that are rendered redundant by that Differential. Likewise,
1014 when a Full backup on a client completed, it would automatically purge
1015 all Differential and Incremental jobs obsoleted by that Full backup.
1016 This would let people minimize the number of tapes they're keeping on
1017 hand without having to master the art of retention times.
1018 - When doing a Backup send all attributes back to the Director, who
1019 would then figure out what files have been deleted.
1020 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1021 explicit permission to do so. It should also mark the tape in error
1022 if there is an error.
1023 - Cancel waiting for Client connect in SD if FD goes away.
1025 - Implement timeout in response() when it should come quickly.
1026 - Implement a Slot priority (loaded/not loaded).
1027 - Implement "vacation" Incremental only saves.
1028 - Implement create "FileSet"?
1029 - Add prefixlinks to where or not where absolute links to FD.
1030 - Issue message to mount a new tape before the rewind.
1031 - Simplified client job initiation for portables.
1032 - If SD cannot open a drive, make it periodically retry.
1033 - Add more of the config info to the tape label.
1035 - If tape is marked read-only, then try opening it read-only rather than
1036 failing, and remember that it cannot be written.
1037 - Refine SD waiting output:
1038 Device is being positioned
1039 > Device is being positioned for append
1040 > Device is being positioned to file x
1042 - Figure out some way to estimate output size and to avoid splitting
1043 a backup across two Volumes -- this could be useful for writing CDROMs
1044 where you really prefer not to have it split -- not serious.
1045 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1046 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1047 actual data on the Volume and compare it.
1048 - Implement Bacula plugins -- design API
1049 - Make bcopy read through bad tape records.
1050 - Program files (i.e. execute a program to read/write files).
1051 Pass read date of last backup, size of file last time.
1052 - Add Signature type to File DB record.
1053 - CD into subdirectory when open()ing files for backup to
1054 speed up things. Test with testfind().
1055 - Priority job to go to top of list.
1056 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1057 - Implement some way for the Console to dynamically create a job.
1058 - Solaris -I on tar for include list
1059 - Need a verbose mode in restore, perhaps to bsr.
1060 - bscan without -v is too quiet -- perhaps show jobs.
1061 - Add code to reject whole blocks if not wanted on restore.
1062 - Check if we can increase Bacula FD priorty in Win2000
1063 - Make sure the MaxVolFiles is fully implemented in SD
1064 - Check if both CatalogFiles and UseCatalog are set to SD.
1065 - Possibly add email to Watchdog if drive is unmounted too
1066 long and a job is waiting on the drive.
1067 - After unmount, if restore job started, ask to mount.
1068 - Add UA rc and history files.
1069 - put termcap (used by console) in ./configure and
1070 allow -with-termcap-dir.
1071 - Fix Autoprune for Volumes to respect need for full save.
1072 - Compare tape to Client files (attributes, or attributes and data)
1073 - Make all database Ids 64 bit.
1074 - Allow console commands to detach or run in background.
1075 - Fix status delay on storage daemon during rewind.
1076 - Add SD message variables to control operator wait time
1077 - Maximum Operator Wait
1078 - Minimum Message Interval
1079 - Maximum Message Interval
1080 - Send Operator message when cannot read tape label.
1081 - Verify level=Volume (scan only), level=Data (compare of data to file).
1082 Verify level=Catalog, level=InitCatalog
1084 - Add keyword search to show command in Console.
1085 - Events : tape has more than xxx bytes.
1086 - Complete code in Bacula Resources -- this will permit
1087 reading a new config file at any time.
1088 - Handle ctl-c in Console
1089 - Implement script driven addition of File daemon to config files.
1090 - Think about how to make Bacula work better with File (non-tape) archives.
1091 - Write Unix emulator for Windows.
1092 - Put memory utilization in Status output of each daemon
1093 if full status requested or if some level of debug on.
1094 - Make database type selectable by .conf files i.e. at runtime
1095 - Set flag for uname -a. Add to Volume label.
1096 - Restore files modified after date
1097 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1098 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1099 - Timout a job or terminate if link goes down, or reopen link and query.
1100 - Concept of precious tapes (cannot be reused).
1101 - Make bcopy copy with a single tape drive.
1102 - Permit changing ownership during restore.
1105 > My suggestion: Add a feature on the systray menu-icon menu to request
1106 > an immediate backup now. This would be useful for laptop users who may
1107 > not be on the network when the regular scheduled backup is run.
1109 > My wife's suggestion: Add a setting to the win32 client to allow it to

1111 > displaying a "System will shut down in one minute, click here to cancel"
1112 > warning dialog). This would be useful for sites that want user
1113 > woorkstations to be shut down overnight to save power.
1116 - Autolabel should be specified by DIR instead of SD.
1118 - Add media capacity
1119 - AutoScan (check checksum of tape)
1120 - Format command = "format /dev/nst0"
1124 - Seek resolution (usually corresponds to buffer size)
1125 - EODErrorCode=ENOSPC or code
1126 - Partial Read error code
1127 - Partial write error code
1128 - Nonformatted read error
1129 - Nonformatted write error
1130 - WriteProtected error
1134 - IgnoreCloseErrors=yes
1144 - FD sends unsaved file list to Director at end of job (see
1146 - File daemon should build list of files skipped, and then
1147 at end of save retry and report any errors.
1148 - Write a Storage daemon that uses pipes and
1149 standard Unix programs to write to the tape.
1151 - Need something that monitors the JCR queue and
1152 times out jobs by asking the deamons where they are.
1153 - Enhance Jmsg code to permit buffering and saving to disk.
1154 - device driver = "xxxx" for drives.
1155 - Verify from Volume
1156 - Ensure that /dev/null works
1157 - Need report class for messages. Perhaps
1158 report resource where report=group of messages
1159 - enhance scan_attrib and rename scan_jobtype, and
1160 fill in code for "since" option
1161 - Director needs a time after which the report status is sent
1162 anyway -- or better yet, a retry time for the job.
1163 - Don't reschedule a job if previous incarnation is still running.
1164 - Some way to automatically backup everything is needed????
1165 - Need a structure for pending actions:
1167 - termination status (part of buffered msgs?)
1169 Read, Write, Clean, Delete
1170 - Login to Bacula; Bacula users with different permissions:
1171 owner, group, user, quotas
1172 - Store info on each file system type (probably in the job header on tape.
1173 This could be the output of df; or perhaps some sort of /etc/mtab record.

1178 Subject: RE: [Bacula-users] future large programming jobs
1179 Date: Thu, 26 Feb 2004 11:34:54 -0600
1181 I noticed the subject thread and thought I would offer the following
1182 merely as sources of ideas, i.e. something to think about, not even as
1183 strong as a request. In my former life (before retiring) I often
1184 dealt with backups and storage management issues/products as a
1185 developer and as a consultant. I am currently migrating my personal
1186 network from amanda to bacula specifically because of the ability to
1187 cross media boundaries during storing backups.
1188 Are you familiar with the commercial product called ADSM (I think IBM
1189 now sells it under the Tivoli label)? It has a couple of interesting
1190 ideas that may apply to the following topics.
1192 1. Migration: Consider that when you need to restore a system, there
1193 may be pressure to hurry. If all the information for a single client
1194 can eventually end up on the same media (and in chronological order),
1195 the restore is facillitated by not having to search past information
1196 from other clients. ADSM has the concept of "client affinity" that
1197 may be associated with it's storage pools. It seems to me that this
1198 concept (as an optional feature) might fit in your architecture for
1201 ADSM also has the concept of defining one or more storage pools as
1202 "copy pools" (almost mirrors, but only in the sense of contents).
1203 These pools provide the ability to have duplicte data stored both
1204 onsite and offsite. The copy process can be scheduled to be handled
1205 by their storage manager during periods when there is no backup
1206 activity. Again, the migration process might be a place to consider
1207 implementing something like this.
1210 > It strikes me that it would be very nice to be able to do things
1212 > have the Job(s) backing up the machines run, and once they have all
1213 > completed, start a migration job to copy the data from disks Volumes

1218 > mechanism described below would probably make it very easy.
1220 This is the goal. In the first step (before events), you simply
1222 the Migration to tape later.
1224 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1225 the database. Once a file (unique by path and metadata such as dates,
1226 size, ownership, etc.) is in a copy pool, no more copies are made. In
1227 other words, when you start ADSM, it begins like your concept of a
1228 base job. After that it is in the "incremental" mode. You can
1229 configure the number of "generations" of files to be retained, plus a
1230 retention date after which even old generations are purged. The
1231 database tracks the contents of media and projects the percentage of
1232 each volume that is valid. When the valid content of a volume drops
1233 below a configured percentage, the valid data are migrated to another
1234 volume and the old volume is marked as empty. Note, this requires
1235 ADSM to have an idea of the contents of a client, i.e. marking the
1236 database when an existing file was deleted, but this would solve your
1237 issue of restoring a client without restoring deleted files.
1239 This is pretty far from what bacula now does, but if you are going to
1240 rip things up for Base jobs,.....
1241 Also, the benefits of this are huge for very large shops, especially
1242 with media robots, but are a pain for shops with manual media
1246 > Base jobs sound pretty useful, but I'm not dying for them.
1248 Nobody is dying for them, but when you see what it does, you will die
1251 3. Restoring deleted files: Since I think my comments in (2) above
1252 have low probability of implementation, I'll also suggest that you
1253 could approach the issue of deleted files by a mechanism of having the
1254 fd report to the dir, a list of all files on the client for every
1255 backup job. The dir could note in the database entry for each file
1256 the date that the file was seen. Then if a restore as of date X takes
1257 place, only files that exist from before X until after X would be
1258 restored. Probably the major cost here is the extra date container in
1259 each row of the files table.
1261 Thanks for "listening". I hope some of this helps. If you want to
1262 contact me, please send me an email - I read some but not all of the
1263 mailing list traffic and might miss a reply there.
1265 Please accept my compliments for bacula. It is doing a great job for
1266 me!! I sympathize with you in the need to wrestle with excelence in
1267 execution vs. excelence in feature inclusion.
1272 ==============================
1275 - Design at hierarchial storage for Bacula. Migration and Clone.
1276 - Implement FSM (File System Modules).
1277 - Audit M_ error codes to ensure they are correct and consistent.
1278 - Add variable break characters to lex analyzer.
1279 Either a bit mask or a string of chars so that
1280 the caller can change the break characters.
1281 - Make a single T_BREAK to replace T_COMMA, etc.
1282 - Ensure that File daemon and Storage daemon can
1283 continue a save if the Director goes down (this
1284 is NOT currently the case). Must detect socket error,
1285 buffer messages for later.
1286 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1287 - Add ability to backup to two Storage devices (two SD sessions) at
1288 the same time -- e.g. onsite, offsite.
1289 - Add the ability to consolidate old backup sets (basically do a restore
1290 to tape and appropriately update the catalog). Compress Volume sets.
1291 Might need to spool via file is only one drive is available.
1292 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1293 someway to do so with every volume that has less than x% valid
1297 Migration: Move a backup from one Volume to another
1298 Clone: Copy a backup -- two Volumes
1300 Bacula Migration is based on Jobs (apparently Networker is file by file).

1306 Highwater mark (keep total size)
1311 ======================================================
1313 It is somewhat like a Full save becomes an incremental since
1314 the Base job (or jobs) plus other non-base files.
1316 - A Base backup is same as Full backup, just different type.
1317 - New BaseFiles table that contains:
1319 BaseJobId - Base JobId referenced for this FileId (needed ???)
1320 JobId - JobId currently running
1321 FileId - File not backed up, exists in Base Job
1322 FileIndex - FileIndex from Base Job.
1323 i.e. for each base file that exists but is not saved because
1324 it has not changed, the File daemon sends the JobId, BaseId,
1325 FileId, FileIndex back to the Director who creates the DB entry.
1326 - To initiate a Base save, the Director sends the FD
1327 the FileId, and full filename for each file in the Base.
1328 - When the FD finds a Base file, he requests the Director to
1329 send him the full File entry (stat packet plus MD5), or
1330 conversely, the FD sends it to the Director and the Director
1331 says yes or no. This can be quite rapid if the FileId is kept
1332 by the FD for each Base Filename.
1333 - It is probably better to have the comparison done by the FD
1334 despite the fact that the File entry must be sent across the
1336 - An alternative would be to send the FD the whole File entry
1337 from the start. The disadvantage is that it requires a lot of
1338 space. The advantage is that it requires less communications
1340 - The Job record must be updated to indicate that one or more
1342 - At end of Job, FD returns:
1343 1. Count of base files/bytes not written to tape (i.e. matches)
1344 2. Count of base file that were saved i.e. had changed.
1345 - No tape record would be written for a Base file that matches, in the
1346 same way that no tape record is written for Incremental jobs where
1347 the file is not saved because it is unchanged.
1348 - On a restore, all the Base file records must explicitly be
1349 found from the BaseFile tape. I.e. for each Full save that is marked
1350 to have one or more Base Jobs, search the BaseFile for all occurrences
1352 - An optimization might be to make the BaseFile have:
1358 This would avoid the need to explicitly fetch each File record for
1359 the Base job. The Base Job record will be fetched to get the
1360 VolSessionId and VolSessionTime.
1361 =========================================================
1364 ==========================================================
1366 For each Incremental job that is run, there may be files that
1367 were found but not saved because they were locked (this applies
1368 only to Windows). Such a system could send back to the Director
1369 a list of Unsaved files.
1371 - New UnSavedFiles table that contains:
1375 - Then in the next Incremental job, the list of Unsaved Files will be
1376 feed to the FD, who will ensure that they are explicitly chosen even
1377 if standard date/time check would not have selected them.

1419 (just to verify it remembers where it came from, however it can be

1422 There needs to be a table of drive # to devices somewhere - If there are
1423 multiple changers or drives there may not be a 1:1 correspondance between
1424 changer drive number and system device name - and depending on the way the
1425 drives are hooked up to scsi busses, they may not be linearly numbered
1426 from an offset point either.something like
1428 Autochanger drives = 2
1429 Autochanger drive 0 = /dev/nst1
1430 Autochanger drive 1 = /dev/nst2
1431 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1432 times, not just for multidrive changers. For a 1 drive changer, that's
1438 MTX's manpage (1.2.15):
1439 unload [<slotnum>] [ <drivenum> ]
1440 Unloads media from drive <drivenum> into slot
1441 <slotnum>. If <drivenum> is omitted, defaults to
1442 drive 0 (as do all commands). If <slotnum> is
1443 omitted, defaults to the slot that the drive was
1444 loaded from. Note that there's currently no way
1445 to say 'unload drive 1's media to the slot it
1446 came from', other than to explicitly use that
1447 slot number as the destination.AB

1485 Handling removable disks
1487 From: Karl Cunningham <karlc@keckec.com>
1489 My backups are only to hard disk these days, in removable bays. This is my
1490 idea of how a backup to hard disk would work more smoothly. Some of these
1491 things Bacula does already, but I mention them for completeness. If others
1492 have better ways to do this, I'd like to hear about it.
1494 1. Accommodate several disks, rotated similar to how tapes are. Identified
1495 by partition volume ID or perhaps by the name of a subdirectory.
1496 2. Abort & notify the admin if the wrong disk is in the bay.
1497 3. Write backups to different subdirectories for each machine to be backed
1499 4. Volumes (files) get created as needed in the proper subdirectory, one
1501 5. When a disk is recycled, remove or zero all old backup files. This is
1502 important as the disk being recycled may be close to full. This may be
1503 better done manually since the backup files for many machines may be
1504 scattered in many subdirectories.
1509 - Make sure that all do_prompt() calls in Dir check for
1510 -1 (error) and -2 (cancel) returns.
1511 - Fix foreach_jcr() to have free_jcr() inside next().
1512 jcr=jcr_walk_start();
1513 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1516 - A Volume taken from Scratch should take on the retention period
1518 - Correct doc for Maximum Changer Wait (and others) accepting only
1520 - Implement status that shows why a job is being held in reserve, or
1521 rather why none of the drives are suitable.
1522 - Implement a way to disable a drive (so you can use the second
1523 drive of an autochanger, and the first one will not be used or
1525 - Make sure Maximum Volumes is respected in Pools when adding
1526 Volumes (e.g. when pulling a Scratch volume).
1527 - Keep same dcr when switching device ...
1528 - Implement code that makes the Dir aware that a drive is an
1529 autochanger (so the user doesn't need to use the Autochanger = yes
1531 - Make catalog respect ACL.
1532 - Add recycle count to Media record.
1533 - Add initial write date to Media record.
1534 - Fix store_yesno to be store_bitmask.
