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.
19 - Some users claim that they must do two prune commands to get a
20 Volume marked as purged.
21 - Print warning message if LANG environment variable does not specify
23 === Migration from David ===
27 Name = "<poolname>-migrate"
31 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
32 Client | PoolResidence | Volume | JobName | SQLquery
33 Migration Selection Pattern = "regexp"
34 Next Pool = <override>
37 There should be no need for a Level (migration is always Full, since you
38 don't calculate differential/incremental differences for migration),
39 Storage should be determined by the volume types in the pool, and Client
40 is really a selection issue. Migration should always occur to the
41 NextPool defined in the pool definition. If no nextpool is defined, the
42 job should end with a reason of "no place to go". If Next Pool statement
43 is present, we override the check in the pool definition and use the
46 Here's how I'd define Migration Selection Types:
48 LowestUtil -- Identify the volume in the pool with the least data on it
49 and empty it. No Migration Selection Pattern required.
51 OldestVol -- Identify the LRU volume with data written, and empty it. No
52 Migration Selection Pattern required.
54 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
55 (starting with most full volumes) until pool occupancy drops below
56 <lowmig>. Pool highmig and lowmig values are in pool definition, no
57 Migration Selection Pattern required.
59 Client -- Migrate data from selected client only. Migration Selection
60 Pattern regexp provides pattern to select client names, eg ^FS00* makes
61 all client names starting with FS00 eligible for migration.
63 PoolResidence -- Migrate data sitting in pool for longer than
64 PoolResidence value in pool definition. Migration Selection Pattern
65 optional; if specified, override value in pool definition (value in
68 Volume -- Migrate all data on specified volumes. Migration Selection
69 Pattern regexp provides selection criteria for volumes to be migrated.
70 Volumes must exist in pool to be eligible for migration.
72 Jobname -- Migration all jobs matching name. Migration Selection Pattern
73 regexp provides pattern to select jobnames existing in pool.
75 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
76 Migration Selection Pattern contains SQL query to execute; should return
77 a list of 1 or more jobuids to migrate.
79 [ possibly a Python event -- kes ]
81 - Network error on Win32 should set Win32 error code.
82 - What happens when you rename a Disk Volume?
83 - Job retention period in a Pool (and hence Volume). The job would
85 - Detect resource deadlock in Migrate when same job wants to read
86 and write the same device.
87 - Make hardlink code at line 240 of find_one.c use binary search.
88 - Queue warning/error messages during restore so that they
89 are reported at the end of the report rather than being
90 hidden in the file listing ...
91 - Look at -D_FORTIFY_SOURCE=2
92 - Add Win32 FileSet definition somewhere
93 - Look at fixing restore status stats in SD.
94 - Make selection of Database used in restore correspond to
96 - Implement a mode that says when a hard read error is
97 encountered, read many times (as it currently does), and if the
98 block cannot be read, skip to the next block, and try again. If
99 that fails, skip to the next file and try again, ...
101 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
102 insert into LevelType (LevelType,LevelTypeLong) values
106 - Add ACL to restore only to original location.
107 - Add a recursive mark command (rmark) to restore.
108 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
109 of the same level and does not permit multiple simultaneous
110 running of that Job (i.e. lets any previous invocation finish
111 before doing Interval testing).
112 - Look at simplifying File exclusions.
113 - New directive "Delete purged Volumes"
114 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
115 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
116 see if it become stable and I just have to supervise
118 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
119 PoolId, and when it is empty remove it.
120 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
122 - Allow Check Labels to be used with Bacula labels.
123 - "Resuming" a failed backup (lost line for example) by using the
124 failed backup as a sort of "base" job.
126 - Email to the user when the tape is about to need changing x
127 days before it needs changing.
128 - Command to show next tape that will be used for a job even
129 if the job is not scheduled.
130 - From: Arunav Mandal <amandal@trolltech.com>
131 1. When jobs are running and bacula for some reason crashes or if I do a
132 restart it remembers and jobs it was running before it crashed or restarted
133 as of now I loose all jobs if I restart it.
135 2. When spooling and in the midway if client is disconnected for instance a
136 laptop bacula completely discard the spool. It will be nice if it can write
137 that spool to tape so there will be some backups for that client if not all.
139 3. We have around 150 clients machines it will be nice to have a option to
140 upgrade all the client machines bacula version automatically.
142 4. Atleast one connection should be reserved for the bconsole so at heavy load
143 I should connect to the director via bconsole which at sometimes I can't
145 5. Another most important feature that is missing, say at 10am I manually
146 started backup of client abc and it was a full backup since client abc has
147 no backup history and at 10.30am bacula again automatically started backup of
148 client abc as that was in the schedule. So now we have 2 multiple Full
149 backups of the same client and if we again try to start a full backup of
150 client backup abc bacula won't complain. That should be fixed.
152 - Fix bpipe.c so that it does not modify results pointer.
153 ***FIXME*** calling sequence should be changed.
154 - For Windows disaster recovery see http://unattended.sf.net/
155 - regardless of the retention period, Bacula will not prune the
156 last Full, Diff, or Inc File data until a month after the
157 retention period for the last Full backup that was done.
158 - update volume=xxx --- add status=Full
159 - Remove old spool files on startup.
160 - Exclude SD spool/working directory.
161 - Refuse to prune last valid Full backup. Same goes for Catalog.
163 - Make a callback when Rerun failed levels is called.
164 - Give Python program access to Scheduled jobs.
165 - Add setting Volume State via Python.
166 - Python script to save with Python, not save, save with Bacula.
167 - Python script to do backup.
169 - Change the Priority, Client, Storage, JobStatus (error)
170 at the start of a job.
171 - Why is SpoolDirectory = /home/bacula/spool; not reported
172 as an error when writing a DVD?
173 - Make bootstrap file handle multiple MediaTypes (SD)
174 - Remove all old Device resource code in Dir and code to pass it
175 back in SD -- better, rework it to pass back device statistics.
176 - Check locking of resources -- be sure to lock devices where previously
177 resources were locked.
178 - The last part is left in the spool dir.
181 - In restore don't compare byte count on a raw device -- directory
182 entry does not contain bytes.
183 - To mark files as deleted, run essentially a Verify to disk, and
184 when a file is found missing (MarkId != JobId), then create
185 a new File record with FileIndex == -1. This could be done
186 by the FD at the same time as the backup.
190 MA = (last_MA * 3 + rate) / 4
191 rate = (bytes - last_bytes) / (runtime - last_runtime)
192 - Max Vols limit in Pool off by one?
193 - Implement Files/Bytes,... stats for restore job.
194 - Implement Total Bytes Written, ... for restore job.
195 - Despool attributes simultaneously with data in a separate
196 thread, rejoined at end of data spooling.
197 - 7. Implement new Console commands to allow offlining/reserving drives,
198 and possibly manipulating the autochanger (much asked for).
199 - Add start/end date editing in messages (%t %T, %e?) ...
200 - Add ClientDefs similar to JobDefs.
201 - Print more info when bextract -p accepts a bad block.
202 - Fix FD JobType to be set before RunBeforeJob in FD.
203 - Look at adding full Volume and Pool information to a Volume
204 label so that bscan can get *all* the info.
205 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
206 and there is only one volume in the pool, refuse to do it -- otherwise
207 he fills the Volume, then immediately starts reusing it.
208 - Implement copies and stripes.
209 - Add history file to console.
210 - Each file on tape creates a JobMedia record. Peter has 4 million
211 files spread over 10000 tape files and four tapes. A restore takes
212 16 hours to build the restore list.
213 - Add and option to check if the file size changed during backup.
214 - Make sure SD deletes spool files on error exit.
215 - Delete old spool files when SD starts.
216 - When labeling tapes, if you enter 000026, Bacula uses
217 the tape index rather than the Volume name 000026.
218 - Add offline tape command to Bacula console.
220 Enter MediaId or Volume name: 32
221 Enter new Volume name: DLT-20Dec04
222 Automatically selected Pool: Default
223 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

228 askdir.c:219 NULL Volume name. This shouldn't happen!!!
229 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
230 Label command failed for Volume DLT-20Dec04.
231 Do not forget to mount the drive!!!
232 - Bug: if a job is manually scheduled to run later, it does not appear
233 in any status report and cannot be cancelled.
235 ==== Keeping track of deleted files ====
236 My "trick" for keeping track of deletions is the following.
237 Assuming the user turns on this option, after all the files
238 have been backed up, but before the job has terminated, the
239 FD will make a pass through all the files and send their
240 names to the DIR (*exactly* the same as what a Verify job
241 currently does). This will probably be done at the same
242 time the files are being sent to the SD avoiding a second
243 pass. The DIR will then compare that to what is stored in
244 the catalog. Any files in the catalog but not in what the
245 FD sent will receive a catalog File entry that indicates
246 that at that point in time the file was deleted.
248 During a restore, any file initially picked up by some
249 backup (Full, ...) then subsequently having a File entry
250 marked "delete" will be removed from the tree, so will not
251 be restored. If a file with the same name is later OK it
252 will be inserted in the tree -- this already happens. All
253 will be consistent except for possible changes during the
256 Since I'm on the subject, some of you may be wondering what
257 the utility of the in memory tree is if you are going to
258 restore everything (at least it comes up from time to time
259 on the list). Well, it is still *very* useful because it
260 allows only the last item found for a particular filename
261 (full path) to be entered into the tree, and thus if a file
262 is backed up 10 times, only the last copy will be restored.
263 I recently (last Friday) restored a complete directory, and
264 the Full and all the Differential and Incremental backups
265 spanned 3 Volumes. The first Volume was not even mounted
266 because all the files had been updated and hence backed up
267 since the Full backup was made. In this case, the tree
268 saved me a *lot* of time.
270 Make sure this information is stored on the tape too so
271 that it can be restored directly from the tape.
273 Comments from Martin Simmons (I think they are all covered):
274 Ok, that should cover the basics. There are few issues though:
276 - Restore will depend on the catalog. I think it is better to include the
277 extra data in the backup as well, so it can be seen by bscan and bextract.
279 - I'm not sure if it will preserve multiple hard links to the same inode. Or
280 maybe adding or removing links will cause the data to be dumped again?
282 - I'm not sure if it will handle renamed directories. Possibly it will work
283 by dumping the whole tree under a renamed directory?
285 - It remains to be seen how the backup performance of the DIR's will be
286 affected when comparing the catalog for a large filesystem.
290 How about introducing a Type = MgmtPolicy job type? That job type would
291 be responsible for scanning the Bacula environment looking for specific
292 conditions, and submitting the appropriate jobs for implementing said
296 Name = "Migration-Policy"
298 Policy Selection Job Type = Migrate
299 Scope = "<keyword> <operator> <regexp>"
300 Threshold = "<keyword> <operator> <regexp>"
301 Job Template = <template-name>
304 Where <keyword> is any legal job keyword, <operator> is a comparison
305 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
306 appropriate regexp. I could see an argument for Scope and Threshold
307 being SQL queries if we want to support full flexibility. The
308 Migration-Policy job would then get scheduled as frequently as a site
309 felt necessary (suggested default: every 15 minutes).
314 Name = "Migration-Policy"
316 Policy Selection Job Type = Migration
318 Threshold = "Migration Selection Type = LowestUtil"
319 Job Template = "MigrationTemplate"
322 would select all pools for examination and generate a job based on
323 MigrationTemplate to automatically select the volume with the lowest
324 usage and migrate it's contents to the nextpool defined for that pool.
326 This policy abstraction would be really handy for adjusting the behavior
327 of Bacula according to site-selectable criteria (one thing that pops
328 into mind is Amanda's ability to automatically adjust backup levels
329 depending on various criteria).
335 - Add Pool/Storage override regression test.
336 - Add delete JobId to regression.
337 - Add a regression test for dbcheck.
338 - New test to add bscan to four-concurrent-jobs regression,
339 i.e. after the four-concurrent jobs zap the
340 database as is done in the bscan-test, then use bscan to
341 restore the database, do a restore and compare with the
343 - Add restore of specific JobId to regression (item 3
344 on the restore prompt)
345 - Add IPv6 to regression
346 - Add database test to regression. Test each function like delete,

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

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

362 === From Carsten Menke <bootsy52@gmx.net>
364 Following is a list of what I think in the situations where I'm faced with,
365 could be a usefull enhancement to bacula, which I'm certain other users will
366 benefit from as well.
368 1. NextJob/NextJobs Directive within a Job Resource in the form of
369 NextJobs = job1,job2.
372 I currently solved the problem with running multiple jobs each after each
373 by setting the Max Wait Time for a job to 8 hours, and give
374 the jobs different Priorities. However, there scenarios where
375 1 Job is directly depending on another job, so if the former job fails,
376 the job after it needn't to be run
377 while maybe other jobs should run despite of that
380 A Backup Job and a Verify job, if the backup job fails there is no need to run
381 the verify job, as the backup job already failed. However, one may like
382 to backup the Catalog to disk despite of that the main backup job failed.
385 I see that this is related to the Event Handlers which are on the ToDo
386 list, also it is maybe a good idea to check for the return value and
387 execute different actions based on the return value
390 3. offline capability to bconsole
393 Currently I use a script which I execute within the last Job via the
394 RunAfterJob Directive, to release and eject the tape.
395 So I have to call bconsole "release=Storage-Name" and afterwards
396 mt -f /dev/nst0 eject to get the tape out.
398 If I have multiple Storage Devices, than these may not be /dev/nst0 and
399 I have to modify the script or call it with parameters etc.
400 This would actually not be needed, as everything is already defined
401 in bacula-sd.conf and if I can invoke bconsole with the
402 storage name via $1 in the script than I'm done and information is
405 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
409 For the reason mentioned in 3. to have the ability to call a
410 script with /scripts/foobar %s and in the script use $1
411 to pass the Storage Name to bconsole
413 5. Setting Volume State within a Job Resource
416 Instead of using "Maximum Volume Jobs" in the Pool Resource,
417 I would have the possibilty to define
418 in a Job Resource that after this certain job is run, the Volume State
419 should be set to "Volume State = Used", this give more flexibility (IMHO).
421 6. Localization of Bacula Messages
424 Unfortunatley many,many people I work with don't speak english very well.
425 So if at least the Reporting messages would be localized then they
426 would understand that they have to change the tape,etc. etc.
428 I volunteer to do the german translations, and if I can convince my wife also
429 french and Morre (western african language).
431 7. OK, this is evil, probably bound to security risks and maybe not possible
432 due to the design of bacula.
434 Implementation of Backtics ( `command` ) for shell comand execution to
435 the "Label Format" Directive.
439 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
440 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
441 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
442 the localized name for the day of the week appended to the
443 format string. Then I have the tape labeled automatically with weekday
444 name in the correct language.
446 - Yes, that is surely the case. I probably should turn those into Warning
447 errors. In addition, you just made me think that it might not be bad to
448 add an option to check the file size after backing up the file and
449 report if it changes. This would be done as an option because it would
452 Kern, good idea. If you do do that, mention in the output: file
453 shrunk, or file expanded, just to make it obvious to the user
454 (without having to the refer to file size), just how the file size
457 Would this option be for all file, or just one file? Or a fileset?
458 - Make output from status use html table tags for nicely
459 presenting in a browser.
460 - Can one write tapes faster with 8192 byte block sizes?
461 - Document security problems with the same password for everyone in
462 rpm and Win32 releases.
463 - Browse generations of files.
464 - I've seen an error when my catalog's File table fills up. I
465 then have to recreate the File table with a larger maximum row
466 size. Relevant information is at
467 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
468 "Installing and Configuring MySQL" chapter should talk a bit
469 about this potential problem, and recommend a solution.
470 - For Solaris must use POSIX awk.
471 - Want speed of writing to tape while despooling.
472 - Supported autochanger:
480 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
481 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
482 - Add regex from http://www.pcre.org to Bacula for Win32.
483 - Use only shell tools no make in CDROM package.
484 - Include within include does it work?
485 - Implement a Pool of type Cleaning?
486 - Implement VolReadTime and VolWriteTime in SD
487 - Modify Backing up Your Database to include a bootstrap file.
488 - Think about making certain database errors fatal.
489 - Look at correcting the time jump in the scheduler for daylight
490 savings time changes.
491 - Add a "real" timer to network connections.
492 - Promote to Full = Time period
493 - Check dates entered by user for correctness (month/day/... ranges)
494 - Compress restore Volume listing by date and first file.
495 - Look at patches/bacula_db.b2z postgresql that loops during restore.
497 - Perhaps add read/write programs and/or plugins to FileSets.
498 - How to handle backing up portables ...
499 - Add some sort of guaranteed Interval for upgrading jobs.
500 - Can we write the state file after every job terminates? On Win32
501 the system crashes and the state file is not updated.
504 Documentation to do: (any release a little bit at a time)
505 - Doc to do unmount before removing magazine.
506 - Alternative to static linking "ldd prog" save all binaries listed,
507 restore them and point LD_LIBRARY_PATH to them.
508 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
509 - Document query file format.
510 - Add more documentation for bsr files.
511 - Document problems with Verify and pruning.
512 - Document how to use multiple databases.
513 - VXA drives have a "cleaning required"
514 indicator, but Exabyte recommends preventive cleaning after every 75
517 In this context, it should be noted that Exabyte has a command-line
518 vxatool utility available for free download. (The current version is
519 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
520 test the drive, unload tapes, change drive settings, flash new firmware,
522 Of particular interest in this context is that vxatool <device> -i will
523 report, among other details, the time since last cleaning in tape motion
524 minutes. This information can be retrieved (and settings changed, for
525 that matter) through the generic-SCSI device even when Bacula has the
526 regular tape device locked. (Needless to say, I don't recommend
527 changing tape settings while a job is running.)
528 - Lookup HP cleaning recommendations.
529 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
530 - Document doing table repair
533 ===================================
534 - Add macro expansions in JobDefs.
535 Run Before Job = "SomeFile %{Level} %{Client}"
536 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
537 - Use non-blocking network I/O but if no data is available, use
539 - Use gather write() for network I/O.
540 - Autorestart on crash.
541 - Add bandwidth limiting.
542 - Add acks every once and a while from the SD to keep
543 the line from timing out.
544 - When an error in input occurs and conio beeps, you can back
545 up through the prompt.
546 - Detect fixed tape block mode during positioning by looking at
547 block numbers in btape "test". Possibly adjust in Bacula.
548 - Fix list volumes to output volume retention in some other
549 units, perhaps via a directive.
550 - If opening a tape in read/write mode fails attempt to open
551 it in read-only mode, and mark the tape for read only.
552 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
553 with multiple priorities.
554 - If you use restore replace=never, the directory attributes for
555 non-existent directories will not be restored properly.
557 - see lzma401.zip in others directory for new compression
559 - Minimal autochanger handling in Bacula and in btape.
560 - Look into how tar does not save sockets and the possiblity of
561 not saving them in Bacula (Martin Simmons reported this).
562 - Fix restore jobs so that multiple jobs can run if they
563 are not using the same tape(s).
564 - Allow the user to select JobType for manual pruning/purging.
565 - bscan does not put first of two volumes back with all info in
567 - Implement the FreeBSD nodump flag in chflags.
568 - Figure out how to make named console messages go only to that
569 console and to the non-restricted console (new console class?).
570 - Make restricted console prompt for password if *ask* is set or
571 perhaps if password is undefined.
572 - Implement "from ISO-date/time every x hours/days/weeks/months" in
575 ==== from Marc Schoechlin
576 - the help-command should be more verbose
577 (it should explain the paramters of the different
579 -> its time-comsuming to consult the manual anytime
580 you need a special parameter
581 -> maybe its more easy to maintain this, if the
582 descriptions of that commands are outsourced to
584 - the cd-command should allow complete paths
585 i.e. cd /foo/bar/foo/bar
586 -> if a customer mails me the path to a certain file,
587 its faster to enter the specified directory
588 - if the password is not configured in bconsole.conf
589 you should be asked for it.
590 -> sometimes you like to do restore on a customer-machine
591 which shouldnt know the password for bacula.
592 -> adding the password to the file favours admins
593 to forget to remove the password after usage
595 the protection of that file is less important
596 - long-listed-output of commands should be scrollable
597 like the unix more/less-command does
598 -> if someone runs 200 and more machines, the lists could
599 be a little long and complex
600 - command-output should be shown column by column
601 to reduce scrolling and to increase clarity
603 - lsmark should list the selected files with full
605 - wildcards for selecting and file and directories would be nice
606 - any actions should be interuptable with STRG+C
607 - command-expansion would be pretty cool
609 - When the replace Never option is set, new directory permissions
610 are not restored. See bug 213. To fix this requires creating a
611 list of newly restored directories so that those directory
612 permissions *can* be restored.
613 - Compaction of Disk space by "migrating" Volumes that have pruned
614 Jobs (what criteria? size, #jobs, time).
615 - Add prune all command
616 - Document fact that purge can destroy a part of a restore by purging
617 one volume while others remain valid -- perhaps mark Jobs.
618 - Add multiple-media-types.txt
619 - look at mxt-changer.html
620 - Make ? do a help command (no return needed).
621 - Implement restore directory.
622 - Document streams and how to implement them.
623 - Try not to re-backup a file if a new hard link is added.
624 - Add feature to backup hard links only, but not the data.
625 - Fix stream handling to be simpler.
626 - Add Priority and Bootstrap to Run a Job.
627 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
629 - Remove View FileSet button from Run a Job dialog.
630 - Handle prompt for restore job at end of Restore command.
631 - Add display of total selected files to Restore window.
632 - Add tree pane to left of window.
633 - Add progress meter.
634 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
635 - Document writing to a CD/DVD with Bacula.
636 - Add a "base" package to the window installer for pthreadsVCE.dll
637 which is needed by all packages.
638 - Add message to user to check for fixed block size when the forward
639 space test fails in btape.
640 - When unmarking a directory check if all files below are unmarked and
641 then remove the + flag -- in the restore tree.
642 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
643 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
644 - Revisit the question of multiple Volumes (disk) on a single device.
645 - Add a block copy option to bcopy.
646 - Investigate adding Mac Resource Forks.
647 - Finish work on Gnome restore GUI.
648 - Fix "llist jobid=xx" where no fileset or client exists.
649 - For each job type (Admin, Restore, ...) require only the really necessary
650 fields.- Pass Director resource name as an option to the Console.
651 - Add a "batch" mode to the Console (no unsolicited queries, ...).
652 - Add a .list all files in the restore tree (probably also a list all files)
653 Do both a long and short form.
654 - Allow browsing the catalog to see all versions of a file (with
655 stat data on each file).
656 - Restore attributes of directory if replace=never set but directory
658 - Use SHA1 on authentication if possible.
659 - See comtest-xxx.zip for Windows code to talk to USB.
660 - Add John's appended files:
661 Appended = { /files/server/logs/http/*log }
662 and such files would be treated as follows.On a FULL backup, they would
663 be backed up like any other file.On an INCREMENTAL backup, where a
664 previous INCREMENTAL or FULL was already in thecatalogue and the length
665 of the file wasgreater than the length of the last backup, only thedata
666 added since the last backup will be dumped.On an INCREMENTAL backup, if
667 the length of the file is less than thelength of the file with the same
668 name last backed up, the completefile is dumped.On Windows systems, with
669 creation date of files, we can be evensmarter about this and not count
670 entirely upon the length.On a restore, the full and all incrementals
671 since it will beapplied in sequence to restore the file.
672 - Check new HAVE_WIN32 open bits.
673 - Check if the tape has moved before writing.
674 - Handling removable disks -- see below:
675 - Keep track of tape use time, and report when cleaning is necessary.
676 - Add FromClient and ToClient keywords on restore command (or
677 BackupClient RestoreClient).
678 - Implement a JobSet, which groups any number of jobs. If the
679 JobSet is started, all the jobs are started together.
680 Allow Pool, Level, and Schedule overrides.
681 - Enhance cancel to timeout BSOCK packets after a specific delay.
682 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
683 ua_status.!!! Thanks to Alan Brown for this tip.
684 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
685 correctly for multiple simultaneous jobs.
686 - Correct code so that FileSet MD5 is calculated for < and | filename
688 - Implement the Media record flag that indicates that the Volume does disk
690 - Implement VolAddr, which is used when Volume is addressed like a disk,
691 and form it from VolFile and VolBlock.
692 - Make multiple restore jobs for multiple media types specifying
693 the proper storage type.
694 - Fix fast block rejection (stored/read_record.c:118). It passes a null
695 pointer (rec) to try_repositioning().
696 - Look at extracting Win data from BackupRead.
697 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
698 which would take precidence over the Catalog "JobRetention".
699 - Implement Label Format in Add and Label console commands.
700 - Possibly up network buffers to 65K. Put on variable.
701 - Put email tape request delays on one or more variables. User wants
702 to cancel the job after a certain time interval. Maximum Mount Wait?
703 - Job, Client, Device, Pool, or Volume?
704 Is it possible to make this a directive which is *optional* in multiple
705 resources, like Level? If so, I think I'd make it an optional directive
706 in Job, Client, and Pool, with precedence such that Job overrides Client
707 which in turn overrides Pool.
709 - New Storage specifications:
710 - Want to write to multiple storage devices simultaneously
711 - Want to write to multiple storage devices sequentially (in one job)
712 - Want to read/write simultaneously
713 - Key is MediaType -- it must match
715 Passed to SD as a sort of BSR record called Storage Specification
719 MediaType -> Next MediaType
721 Device -> Next Device
723 Allow multiple Storage specifications
731 Allow Multiple Pool specifications (note, Pool currently
733 Allow Multiple MediaType specifications in Dir conf
734 Allow Multiple Device specifications in Dir conf
735 Perhaps keep this in a single SSR
736 Tie a Volume to a specific device by using a MediaType that
737 is contained in only one device.
738 In SD allow Device to have Multiple MediaTypes
740 - Ideas from Jerry Scharf:
741 First let's point out some big pluses that bacula has for this
743 more importantly it's active. Thank you so much for that
744 even more important, it's not flaky
745 it has an open access catalog, opening many possibilities
746 it's pushing toward heterogeneous systems capability
748 Macintosh file client
749 macs are an interesting niche, but I fear a server is a rathole
750 working bare iron recovery for windows
751 the option for inc/diff backups not reset on fileset revision
752 a) use both change and inode update time against base time
753 b) do the full catalog check (expensive but accurate)
754 sizing guide (how much system is needed to back up N systems/files)
755 consultants on using bacula in building a disaster recovery system
757 or how to get at fancy things that one could do with bacula
758 logwatch code for bacula logs (or similar)
759 linux distro inclusion of bacula (brings good and bad, but necessary)
760 win2k/XP server capability (icky but you asked)
761 support for Oracle database ??
763 - Look at adding SQL server and Exchange support for Windows.
764 - Make dev->file and dev->block_num signed integers so that -1 can
765 be an invalid value which happens with BSR.
766 - Create VolAddr for disk files in place of VolFile and VolBlock. This
767 is needed to properly specify ranges.
768 - Add progress of files/bytes to SD and FD.
769 - Print warning message if FileId > 4 billion
770 - do a "messages" before the first prompt in Console
771 - Client does not show busy during Estimate command.
772 - Implement Console mtx commands.
773 - Implement a Mount Command and an Unmount Command where
774 the users could specify a system command to be performed
775 to do the mount, after which Bacula could attempt to
776 read the device. This is for Removeable media such as a CDROM.
777 - Most likely, this mount command would be invoked explicitly
778 by the user using the current Console "mount" and "unmount"
779 commands -- the Storage Daemon would do the right thing
780 depending on the exact nature of the device.
781 - As with tape drives, when Bacula wanted a new removable
782 disk mounted, it would unmount the old one, and send a message
783 to the user, who would then use "mount" as described above
784 once he had actually inserted the disk.
785 - Implement dump/print label to UA
786 - Spool to disk only when the tape is full, then when a tape is hung move
788 - bextract is sending everything to the log file ****FIXME****
789 - Allow multiple Storage specifications (or multiple names on
790 a single Storage specification) in the Job record. Thus a job
791 can be backed up to a number of storage devices.
792 - Implement some way for the File daemon to contact the Director
793 to start a job or pass its DHCP obtained IP number.
794 - Implement a query tape prompt/replace feature for a console
795 - Copy console @ code to gnome2-console
796 - Make AES the only encryption algorithm see
797 http://csrc.nist.gov/CryptoToolkit/aes/). It's
798 an officially adopted standard, has survived peer
799 review, and provides keys up to 256 bits.
800 - Take a careful look at SetACL http://setacl.sourceforge.net
801 - Make tree walk routines like cd, ls, ... more user friendly
802 by handling spaces better.
803 - Make sure that Bacula rechecks the tape after the 20 min wait.
804 - Set IO_NOWAIT on Bacula TCP/IP packets.
805 - Try doing a raw partition backup and restore by mounting a
808 Yes, it would allow to highly automatic the request for new tapes. If a
809 tape is empty, bacula reads the barcodes (native or simulated), and if
810 an unused tape is found, it runs the label command with all the
811 necessary parameters.
813 By the way can bacula automatically "move" an empty/purged volume say
814 in the "short" pool to the "long" pool if this pool runs out of volume
816 - What to do about "list files job=xxx".
817 - Get and test MySQL 4.0
818 - Look at how fuser works and /proc/PID/fd that is how Nic found the
819 file descriptor leak in Bacula.
820 - Implement WrapCounters in Counters.
821 - Add heartbeat from FD to SD if hb interval expires.
822 - Can we dynamically change FileSets?
823 - If pool specified to label command and Label Format is specified,
824 automatically generate the Volume name.
825 - Why can't SQL do the filename sort for restore?
826 - Add ExhautiveRestoreSearch
827 - Look at the possibility of loading only the necessary
828 data into the restore tree (i.e. do it one directory at a
829 time as the user walks through the tree).
830 - Possibly use the hash code if the user selects all for a restore command.
831 - Fix "restore all" to bypass building the tree.
832 - Prohibit backing up archive device (findlib/find_one.c:128)
833 - Implement Release Device in the Job resource to unmount a drive.
834 - Implement Acquire Device in the Job resource to mount a drive,
835 be sure this works with admin jobs so that the user can get
836 prompted to insert the correct tape. Possibly some way to say to
837 run the job but don't save the files.
838 - Make things like list where a file is saved case independent for
841 - Use autochanger to handle multiple devices.
842 - On Windows with very long path names, it may be impossible to create
843 a file (and thus restore it) because the total length is too long.
844 We must cd into the directory then create the file without the
846 - Implement a Recycle command
847 - Test a second language e.g. french.
848 - Start working on Base jobs.
849 - Implement UnsavedFiles DB record.
850 - From Phil Stracchino:
851 It would probably be a per-client option, and would be called
852 something like, say, "Automatically purge obsoleted jobs". What it
853 would do is, when you successfully complete a Differential backup of a
854 client, it would automatically purge all Incremental backups for that
855 client that are rendered redundant by that Differential. Likewise,
856 when a Full backup on a client completed, it would automatically purge
857 all Differential and Incremental jobs obsoleted by that Full backup.
858 This would let people minimize the number of tapes they're keeping on
859 hand without having to master the art of retention times.
860 - When doing a Backup send all attributes back to the Director, who
861 would then figure out what files have been deleted.
862 - Currently in mount.c:236 the SD simply creates a Volume. It should have
863 explicit permission to do so. It should also mark the tape in error
864 if there is an error.
865 - Cancel waiting for Client connect in SD if FD goes away.
867 - Implement timeout in response() when it should come quickly.
868 - Implement a Slot priority (loaded/not loaded).
869 - Implement "vacation" Incremental only saves.
870 - Implement create "FileSet"?
871 - Add prefixlinks to where or not where absolute links to FD.
872 - Issue message to mount a new tape before the rewind.
873 - Simplified client job initiation for portables.
874 - If SD cannot open a drive, make it periodically retry.
875 - Add more of the config info to the tape label.
877 - If tape is marked read-only, then try opening it read-only rather than
878 failing, and remember that it cannot be written.
879 - Refine SD waiting output:
880 Device is being positioned
881 > Device is being positioned for append
882 > Device is being positioned to file x
884 - Figure out some way to estimate output size and to avoid splitting
885 a backup across two Volumes -- this could be useful for writing CDROMs
886 where you really prefer not to have it split -- not serious.
887 - Have SD compute MD5 or SHA1 and compare to what FD computes.
888 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
889 actual data on the Volume and compare it.
890 - Implement Bacula plugins -- design API
891 - Make bcopy read through bad tape records.
892 - Program files (i.e. execute a program to read/write files).
893 Pass read date of last backup, size of file last time.
894 - Add Signature type to File DB record.
895 - CD into subdirectory when open()ing files for backup to
896 speed up things. Test with testfind().
897 - Priority job to go to top of list.
898 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
899 - Implement some way for the Console to dynamically create a job.
900 - Solaris -I on tar for include list
901 - Need a verbose mode in restore, perhaps to bsr.
902 - bscan without -v is too quiet -- perhaps show jobs.
903 - Add code to reject whole blocks if not wanted on restore.
904 - Check if we can increase Bacula FD priorty in Win2000
905 - Make sure the MaxVolFiles is fully implemented in SD
906 - Check if both CatalogFiles and UseCatalog are set to SD.
907 - Possibly add email to Watchdog if drive is unmounted too
908 long and a job is waiting on the drive.
909 - After unmount, if restore job started, ask to mount.
910 - Add UA rc and history files.
911 - put termcap (used by console) in ./configure and
912 allow -with-termcap-dir.
913 - Fix Autoprune for Volumes to respect need for full save.
914 - Compare tape to Client files (attributes, or attributes and data)
915 - Make all database Ids 64 bit.
916 - Allow console commands to detach or run in background.
917 - Fix status delay on storage daemon during rewind.
918 - Add SD message variables to control operator wait time
919 - Maximum Operator Wait
920 - Minimum Message Interval
921 - Maximum Message Interval
922 - Send Operator message when cannot read tape label.
923 - Verify level=Volume (scan only), level=Data (compare of data to file).
924 Verify level=Catalog, level=InitCatalog
926 - Add keyword search to show command in Console.
927 - Events : tape has more than xxx bytes.
928 - Complete code in Bacula Resources -- this will permit
929 reading a new config file at any time.
930 - Handle ctl-c in Console
931 - Implement script driven addition of File daemon to config files.
932 - Think about how to make Bacula work better with File (non-tape) archives.
933 - Write Unix emulator for Windows.
934 - Put memory utilization in Status output of each daemon
935 if full status requested or if some level of debug on.
936 - Make database type selectable by .conf files i.e. at runtime
937 - Set flag for uname -a. Add to Volume label.
938 - Restore files modified after date
939 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
940 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
941 - Timout a job or terminate if link goes down, or reopen link and query.
942 - Concept of precious tapes (cannot be reused).
943 - Make bcopy copy with a single tape drive.
944 - Permit changing ownership during restore.

958 - Autolabel should be specified by DIR instead of SD.
961 - AutoScan (check checksum of tape)
962 - Format command = "format /dev/nst0"
966 - Seek resolution (usually corresponds to buffer size)
967 - EODErrorCode=ENOSPC or code
968 - Partial Read error code
969 - Partial write error code
970 - Nonformatted read error
971 - Nonformatted write error
972 - WriteProtected error
976 - IgnoreCloseErrors=yes
986 - FD sends unsaved file list to Director at end of job (see
988 - File daemon should build list of files skipped, and then
989 at end of save retry and report any errors.
990 - Write a Storage daemon that uses pipes and
991 standard Unix programs to write to the tape.
993 - Need something that monitors the JCR queue and
994 times out jobs by asking the deamons where they are.
995 - Enhance Jmsg code to permit buffering and saving to disk.
996 - device driver = "xxxx" for drives.
998 - Ensure that /dev/null works
999 - Need report class for messages. Perhaps
1000 report resource where report=group of messages
1001 - enhance scan_attrib and rename scan_jobtype, and
1002 fill in code for "since" option
1003 - Director needs a time after which the report status is sent
1004 anyway -- or better yet, a retry time for the job.
1005 - Don't reschedule a job if previous incarnation is still running.
1006 - Some way to automatically backup everything is needed????
1007 - Need a structure for pending actions:
1009 - termination status (part of buffered msgs?)
1011 Read, Write, Clean, Delete
1012 - Login to Bacula; Bacula users with different permissions:
1013 owner, group, user, quotas
1014 - Store info on each file system type (probably in the job header on tape.
1015 This could be the output of df; or perhaps some sort of /etc/mtab record.
1017 ========= ideas ===============
1018 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1019 To: <kern@sibbald.com>
1020 Subject: RE: [Bacula-users] future large programming jobs
1021 Date: Thu, 26 Feb 2004 11:34:54 -0600
1023 I noticed the subject thread and thought I would offer the following
1024 merely as sources of ideas, i.e. something to think about, not even as
1025 strong as a request. In my former life (before retiring) I often
1026 dealt with backups and storage management issues/products as a
1027 developer and as a consultant. I am currently migrating my personal
1028 network from amanda to bacula specifically because of the ability to
1029 cross media boundaries during storing backups.
1030 Are you familiar with the commercial product called ADSM (I think IBM
1031 now sells it under the Tivoli label)? It has a couple of interesting
1032 ideas that may apply to the following topics.
1034 1. Migration: Consider that when you need to restore a system, there
1035 may be pressure to hurry. If all the information for a single client
1036 can eventually end up on the same media (and in chronological order),
1037 the restore is facillitated by not having to search past information
1038 from other clients. ADSM has the concept of "client affinity" that
1039 may be associated with it's storage pools. It seems to me that this
1040 concept (as an optional feature) might fit in your architecture for
1043 ADSM also has the concept of defining one or more storage pools as
1044 "copy pools" (almost mirrors, but only in the sense of contents).
1045 These pools provide the ability to have duplicte data stored both
1046 onsite and offsite. The copy process can be scheduled to be handled
1047 by their storage manager during periods when there is no backup
1048 activity. Again, the migration process might be a place to consider
1049 implementing something like this.
1052 > It strikes me that it would be very nice to be able to do things
1054 > have the Job(s) backing up the machines run, and once they have all

1060 > mechanism described below would probably make it very easy.
1062 This is the goal. In the first step (before events), you simply
1064 the Migration to tape later.
1066 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1067 the database. Once a file (unique by path and metadata such as dates,
1068 size, ownership, etc.) is in a copy pool, no more copies are made. In
1069 other words, when you start ADSM, it begins like your concept of a
1070 base job. After that it is in the "incremental" mode. You can
1071 configure the number of "generations" of files to be retained, plus a
1072 retention date after which even old generations are purged. The
1073 database tracks the contents of media and projects the percentage of
1074 each volume that is valid. When the valid content of a volume drops
1075 below a configured percentage, the valid data are migrated to another
1076 volume and the old volume is marked as empty. Note, this requires
1077 ADSM to have an idea of the contents of a client, i.e. marking the
1078 database when an existing file was deleted, but this would solve your
1079 issue of restoring a client without restoring deleted files.
1081 This is pretty far from what bacula now does, but if you are going to
1082 rip things up for Base jobs,.....
1083 Also, the benefits of this are huge for very large shops, especially
1084 with media robots, but are a pain for shops with manual media
1088 > Base jobs sound pretty useful, but I'm not dying for them.
1090 Nobody is dying for them, but when you see what it does, you will die
1093 3. Restoring deleted files: Since I think my comments in (2) above
1094 have low probability of implementation, I'll also suggest that you
1095 could approach the issue of deleted files by a mechanism of having the
1096 fd report to the dir, a list of all files on the client for every
1097 backup job. The dir could note in the database entry for each file
1098 the date that the file was seen. Then if a restore as of date X takes
1099 place, only files that exist from before X until after X would be
1100 restored. Probably the major cost here is the extra date container in
1101 each row of the files table.
1103 Thanks for "listening". I hope some of this helps. If you want to
1104 contact me, please send me an email - I read some but not all of the
1105 mailing list traffic and might miss a reply there.
1107 Please accept my compliments for bacula. It is doing a great job for
1108 me!! I sympathize with you in the need to wrestle with excelence in
1109 execution vs. excelence in feature inclusion.
1114 ==============================
1117 - Design at hierarchial storage for Bacula. Migration and Clone.
1118 - Implement FSM (File System Modules).
1119 - Audit M_ error codes to ensure they are correct and consistent.
1120 - Add variable break characters to lex analyzer.
1121 Either a bit mask or a string of chars so that
1122 the caller can change the break characters.
1123 - Make a single T_BREAK to replace T_COMMA, etc.
1124 - Ensure that File daemon and Storage daemon can
1125 continue a save if the Director goes down (this
1126 is NOT currently the case). Must detect socket error,
1127 buffer messages for later.
1128 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1129 - Add ability to backup to two Storage devices (two SD sessions) at
1130 the same time -- e.g. onsite, offsite.
1131 - Add the ability to consolidate old backup sets (basically do a restore
1132 to tape and appropriately update the catalog). Compress Volume sets.
1133 Might need to spool via file is only one drive is available.
1134 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1135 someway to do so with every volume that has less than x% valid
1139 Migration: Move a backup from one Volume to another
1140 Clone: Copy a backup -- two Volumes
1142 Bacula Migration is based on Jobs (apparently Networker is file by file).
1144 Migration triggered by:
1148 Highwater mark (keep total size)
1153 ======================================================
1155 It is somewhat like a Full save becomes an incremental since
1156 the Base job (or jobs) plus other non-base files.
1158 - A Base backup is same as Full backup, just different type.
1159 - New BaseFiles table that contains:
1161 BaseJobId - Base JobId referenced for this FileId (needed ???)
1162 JobId - JobId currently running
1163 FileId - File not backed up, exists in Base Job
1164 FileIndex - FileIndex from Base Job.
1165 i.e. for each base file that exists but is not saved because
1166 it has not changed, the File daemon sends the JobId, BaseId,
1167 FileId, FileIndex back to the Director who creates the DB entry.
1168 - To initiate a Base save, the Director sends the FD
1169 the FileId, and full filename for each file in the Base.
1170 - When the FD finds a Base file, he requests the Director to
1171 send him the full File entry (stat packet plus MD5), or
1172 conversely, the FD sends it to the Director and the Director
1173 says yes or no. This can be quite rapid if the FileId is kept
1174 by the FD for each Base Filename.
1175 - It is probably better to have the comparison done by the FD
1176 despite the fact that the File entry must be sent across the
1178 - An alternative would be to send the FD the whole File entry
1179 from the start. The disadvantage is that it requires a lot of
1180 space. The advantage is that it requires less communications
1182 - The Job record must be updated to indicate that one or more
1184 - At end of Job, FD returns:
1185 1. Count of base files/bytes not written to tape (i.e. matches)
1186 2. Count of base file that were saved i.e. had changed.
1187 - No tape record would be written for a Base file that matches, in the
1188 same way that no tape record is written for Incremental jobs where
1189 the file is not saved because it is unchanged.
1190 - On a restore, all the Base file records must explicitly be
1191 found from the BaseFile tape. I.e. for each Full save that is marked
1192 to have one or more Base Jobs, search the BaseFile for all occurrences
1194 - An optimization might be to make the BaseFile have:
1200 This would avoid the need to explicitly fetch each File record for
1201 the Base job. The Base Job record will be fetched to get the
1202 VolSessionId and VolSessionTime.
1203 =========================================================
1206 ==========================================================
1208 For each Incremental job that is run, there may be files that
1209 were found but not saved because they were locked (this applies
1210 only to Windows). Such a system could send back to the Director
1211 a list of Unsaved files.
1213 - New UnSavedFiles table that contains:
1217 - Then in the next Incremental job, the list of Unsaved Files will be
1218 feed to the FD, who will ensure that they are explicitly chosen even
1219 if standard date/time check would not have selected them.

1264 There needs to be a table of drive # to devices somewhere - If there are
1265 multiple changers or drives there may not be a 1:1 correspondance between
1266 changer drive number and system device name - and depending on the way the
1267 drives are hooked up to scsi busses, they may not be linearly numbered
1268 from an offset point either.something like
1270 Autochanger drives = 2
1271 Autochanger drive 0 = /dev/nst1
1272 Autochanger drive 1 = /dev/nst2
1273 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1274 times, not just for multidrive changers. For a 1 drive changer, that's
1280 MTX's manpage (1.2.15):
1281 unload [<slotnum>] [ <drivenum> ]
1282 Unloads media from drive <drivenum> into slot
1283 <slotnum>. If <drivenum> is omitted, defaults to
1284 drive 0 (as do all commands). If <slotnum> is
1285 omitted, defaults to the slot that the drive was
1286 loaded from. Note that there's currently no way
1287 to say 'unload drive 1's media to the slot it
1288 came from', other than to explicitly use that
1289 slot number as the destination.AB

1327 Handling removable disks
1329 From: Karl Cunningham <karlc@keckec.com>
1331 My backups are only to hard disk these days, in removable bays. This is my
1332 idea of how a backup to hard disk would work more smoothly. Some of these
1333 things Bacula does already, but I mention them for completeness. If others
1334 have better ways to do this, I'd like to hear about it.
1336 1. Accommodate several disks, rotated similar to how tapes are. Identified
1337 by partition volume ID or perhaps by the name of a subdirectory.
1338 2. Abort & notify the admin if the wrong disk is in the bay.
1339 3. Write backups to different subdirectories for each machine to be backed
1341 4. Volumes (files) get created as needed in the proper subdirectory, one
1343 5. When a disk is recycled, remove or zero all old backup files. This is
1344 important as the disk being recycled may be close to full. This may be
1345 better done manually since the backup files for many machines may be
1346 scattered in many subdirectories.
1351 - Make sure that all do_prompt() calls in Dir check for
1352 -1 (error) and -2 (cancel) returns.
1353 - Fix foreach_jcr() to have free_jcr() inside next().
1354 jcr=jcr_walk_start();
1355 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1358 - A Volume taken from Scratch should take on the retention period
1360 - Correct doc for Maximum Changer Wait (and others) accepting only
1362 - Implement status that shows why a job is being held in reserve, or
1363 rather why none of the drives are suitable.
1364 - Implement a way to disable a drive (so you can use the second
1365 drive of an autochanger, and the first one will not be used or
1367 - Make sure Maximum Volumes is respected in Pools when adding
1368 Volumes (e.g. when pulling a Scratch volume).
1369 - Keep same dcr when switching device ...
1370 - Implement code that makes the Dir aware that a drive is an
1371 autochanger (so the user doesn't need to use the Autochanger = yes
1373 - Make catalog respect ACL.
1374 - Add recycle count to Media record.
1375 - Add initial write date to Media record.
1376 - Fix store_yesno to be store_bitmask.
