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

48 - Restarted jobs have a NULL in the from field.
49 - Modify SD status command to indicate when the SD is writing

135 - It appears to me that you have run into some sort of race
136 condition where two threads want to use the same Volume and they
137 were both given access. Normally that is no problem. However,
138 one thread wanted the particular Volume in drive 0, but it was
139 loaded into drive 1 so it decided to unload it from drive 1 and
140 then loaded it into drive 0, while the second thread went on
141 thinking that the Volume could be used in drive 1 not realizing
142 that in between time, it was loaded in drive 0.
143 I'll look at the code to see if there is some way we can avoid
144 this kind of problem. Probably the best solution is to make the
145 first thread simply start using the Volume in drive 1 rather than
146 transferring it to drive 0.
147 - Fix re-read of last block to check if job has actually written
148 a block, and check if block was written by a different job
149 (i.e. multiple simultaneous jobs writing).
150 - Figure out how to configure query.sql. Suggestion to use m4:
151 == changequote.m4 ===
152 changequote(`[',`]')dnl
153 ==== query.sql.in ===
154 :List next 20 volumes to expire
156 Pool.Name AS PoolName,
161 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
163 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
167 ON Media.PoolId=Pool.PoolId
168 WHERE Media.LastWritten>0
172 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
174 The problem is that it requires m4, which is not present on all machines
176 - Given all the problems with FIFOs, I think the solution is to do something a
177 little different, though I will look at the code and see if there is not some
178 simple solution (i.e. some bug that was introduced). What might be a better
179 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
180 write data to a program rather than the FIFO. For example, suppose you
185 Then, I could imagine if you backup and restore this file with a direct
186 reference as is currently done for fifos, instead, during backup Bacula will
189 /home/kern/my-fifo.backup
191 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
194 /home/kern/my-fifo.restore
196 and send the data backed up to stdout. These programs can either be an
197 executable or a shell script and they need only read/write to stdin/stdout.
199 I think this would give a lot of flexibility to the user without making any
200 significant changes to Bacula.
205 select FilenameId from Filename where Name='';
206 # Get list of all directories referenced in a Backup.

217 === Migration from David ===
218 What I'd like to see:
221 Name = "<poolname>-migrate"
225 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
226 Client | PoolResidence | Volume | JobName | SQLquery
227 Migration Selection Pattern = "regexp"
228 Next Pool = <override>
231 There should be no need for a Level (migration is always Full, since you
232 don't calculate differential/incremental differences for migration),
233 Storage should be determined by the volume types in the pool, and Client
234 is really a selection issue. Migration should always occur to the
235 NextPool defined in the pool definition. If no nextpool is defined, the
236 job should end with a reason of "no place to go". If Next Pool statement
237 is present, we override the check in the pool definition and use the
240 Here's how I'd define Migration Selection Types:
243 Client -- Migrate data from selected client only. Migration Selection
244 Pattern regexp provides pattern to select client names, eg ^FS00* makes
245 all client names starting with FS00 eligible for migration.
247 Jobname -- Migration all jobs matching name. Migration Selection Pattern
248 regexp provides pattern to select jobnames existing in pool.
250 Volume -- Migrate all data on specified volumes. Migration Selection
251 Pattern regexp provides selection criteria for volumes to be migrated.
252 Volumes must exist in pool to be eligible for migration.
256 LowestUtil -- Identify the volume in the pool with the least data on it
257 and empty it. No Migration Selection Pattern required.
259 OldestVol -- Identify the LRU volume with data written, and empty it. No
260 Migration Selection Pattern required.
262 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
263 (starting with most full volumes) until pool occupancy drops below
264 <lowmig>. Pool highmig and lowmig values are in pool definition, no
265 Migration Selection Pattern required.
269 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
270 Migration Selection Pattern contains SQL query to execute; should return
271 a list of 1 or more jobuids to migrate.
273 PoolResidence -- Migrate data sitting in pool for longer than
274 PoolResidence value in pool definition. Migration Selection Pattern
275 optional; if specified, override value in pool definition (value in

453 1. When jobs are running and bacula for some reason crashes or if I do a
454 restart it remembers and jobs it was running before it crashed or restarted
455 as of now I loose all jobs if I restart it.
457 2. When spooling and in the midway if client is disconnected for instance a
458 laptop bacula completely discard the spool. It will be nice if it can write
459 that spool to tape so there will be some backups for that client if not all.
461 3. We have around 150 clients machines it will be nice to have a option to
462 upgrade all the client machines bacula version automatically.
464 4. Atleast one connection should be reserved for the bconsole so at heavy load
465 I should connect to the director via bconsole which at sometimes I can't
467 5. Another most important feature that is missing, say at 10am I manually
468 started backup of client abc and it was a full backup since client abc has
469 no backup history and at 10.30am bacula again automatically started backup of
470 client abc as that was in the schedule. So now we have 2 multiple Full
471 backups of the same client and if we again try to start a full backup of
472 client backup abc bacula won't complain. That should be fixed.
474 - Fix bpipe.c so that it does not modify results pointer.
475 ***FIXME*** calling sequence should be changed.
476 - For Windows disaster recovery see http://unattended.sf.net/
477 - regardless of the retention period, Bacula will not prune the
478 last Full, Diff, or Inc File data until a month after the
479 retention period for the last Full backup that was done.
480 - update volume=xxx --- add status=Full
481 - Remove old spool files on startup.
482 - Exclude SD spool/working directory.
483 - Refuse to prune last valid Full backup. Same goes for Catalog.
485 - Make a callback when Rerun failed levels is called.
486 - Give Python program access to Scheduled jobs.
487 - Add setting Volume State via Python.
488 - Python script to save with Python, not save, save with Bacula.
489 - Python script to do backup.
491 - Change the Priority, Client, Storage, JobStatus (error)
492 at the start of a job.
493 - Why is SpoolDirectory = /home/bacula/spool; not reported
494 as an error when writing a DVD?
495 - Make bootstrap file handle multiple MediaTypes (SD)
496 - Remove all old Device resource code in Dir and code to pass it
497 back in SD -- better, rework it to pass back device statistics.
498 - Check locking of resources -- be sure to lock devices where previously
499 resources were locked.
500 - The last part is left in the spool dir.
503 - In restore don't compare byte count on a raw device -- directory
504 entry does not contain bytes.
508 MA = (last_MA * 3 + rate) / 4
509 rate = (bytes - last_bytes) / (runtime - last_runtime)
510 - Max Vols limit in Pool off by one?
511 - Implement Files/Bytes,... stats for restore job.
512 - Implement Total Bytes Written, ... for restore job.
513 - Despool attributes simultaneously with data in a separate
514 thread, rejoined at end of data spooling.
515 - 7. Implement new Console commands to allow offlining/reserving drives,
516 and possibly manipulating the autochanger (much asked for).
517 - Add start/end date editing in messages (%t %T, %e?) ...
518 - Add ClientDefs similar to JobDefs.
519 - Print more info when bextract -p accepts a bad block.
520 - Fix FD JobType to be set before RunBeforeJob in FD.
521 - Look at adding full Volume and Pool information to a Volume
522 label so that bscan can get *all* the info.
523 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
524 and there is only one volume in the pool, refuse to do it -- otherwise
525 he fills the Volume, then immediately starts reusing it.
526 - Implement copies and stripes.
527 - Add history file to console.
528 - Each file on tape creates a JobMedia record. Peter has 4 million
529 files spread over 10000 tape files and four tapes. A restore takes
530 16 hours to build the restore list.
531 - Add and option to check if the file size changed during backup.
532 - Make sure SD deletes spool files on error exit.
533 - Delete old spool files when SD starts.
534 - When labeling tapes, if you enter 000026, Bacula uses
535 the tape index rather than the Volume name 000026.
536 - Add offline tape command to Bacula console.
538 Enter MediaId or Volume name: 32
539 Enter new Volume name: DLT-20Dec04

550 - Bug: if a job is manually scheduled to run later, it does not appear
551 in any status report and cannot be cancelled.
553 ==== Keeping track of deleted/new files ====
554 - To mark files as deleted, run essentially a Verify to disk, and
555 when a file is found missing (MarkId != JobId), then create
556 a new File record with FileIndex == -1. This could be done
557 by the FD at the same time as the backup.
559 My "trick" for keeping track of deletions is the following.
560 Assuming the user turns on this option, after all the files
561 have been backed up, but before the job has terminated, the
562 FD will make a pass through all the files and send their
563 names to the DIR (*exactly* the same as what a Verify job
564 currently does). This will probably be done at the same
565 time the files are being sent to the SD avoiding a second
566 pass. The DIR will then compare that to what is stored in
567 the catalog. Any files in the catalog but not in what the
568 FD sent will receive a catalog File entry that indicates
569 that at that point in time the file was deleted. This
570 either transmitted to the FD or simultaneously computed in
571 the FD, so that the FD can put a record on the tape that
572 indicates that the file has been deleted at this point.
573 A delete file entry could potentially be one with a FileIndex
574 of 0 or perhaps -1 (need to check if FileIndex is used for
575 some other thing as many of the Bacula fields are "overloaded"
578 During a restore, any file initially picked up by some
579 backup (Full, ...) then subsequently having a File entry
580 marked "delete" will be removed from the tree, so will not
581 be restored. If a file with the same name is later OK it
582 will be inserted in the tree -- this already happens. All
583 will be consistent except for possible changes during the
586 Since I'm on the subject, some of you may be wondering what
587 the utility of the in memory tree is if you are going to
588 restore everything (at least it comes up from time to time
589 on the list). Well, it is still *very* useful because it
590 allows only the last item found for a particular filename
591 (full path) to be entered into the tree, and thus if a file
592 is backed up 10 times, only the last copy will be restored.
593 I recently (last Friday) restored a complete directory, and
594 the Full and all the Differential and Incremental backups
595 spanned 3 Volumes. The first Volume was not even mounted
596 because all the files had been updated and hence backed up
597 since the Full backup was made. In this case, the tree
598 saved me a *lot* of time.
600 Make sure this information is stored on the tape too so
601 that it can be restored directly from the tape.
603 All the code (with the exception of formally generating and
604 saving the delete file entries) already exists in the Verify
605 Catalog command. It explicitly recognizes added/deleted files since
606 the last InitCatalog. It is more or less a "simple" matter of
607 taking that code and adapting it slightly to work for backups.
609 Comments from Martin Simmons (I think they are all covered):
610 Ok, that should cover the basics. There are few issues though:
612 - Restore will depend on the catalog. I think it is better to include the
613 extra data in the backup as well, so it can be seen by bscan and bextract.
615 - I'm not sure if it will preserve multiple hard links to the same inode. Or
616 maybe adding or removing links will cause the data to be dumped again?
618 - I'm not sure if it will handle renamed directories. Possibly it will work
619 by dumping the whole tree under a renamed directory?
621 - It remains to be seen how the backup performance of the DIR's will be
622 affected when comparing the catalog for a large filesystem.
626 How about introducing a Type = MgmtPolicy job type? That job type would
627 be responsible for scanning the Bacula environment looking for specific
628 conditions, and submitting the appropriate jobs for implementing said
632 Name = "Migration-Policy"
634 Policy Selection Job Type = Migrate
635 Scope = "<keyword> <operator> <regexp>"
636 Threshold = "<keyword> <operator> <regexp>"
637 Job Template = <template-name>
640 Where <keyword> is any legal job keyword, <operator> is a comparison
641 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
642 appropriate regexp. I could see an argument for Scope and Threshold
643 being SQL queries if we want to support full flexibility. The
644 Migration-Policy job would then get scheduled as frequently as a site
645 felt necessary (suggested default: every 15 minutes).
650 Name = "Migration-Policy"
652 Policy Selection Job Type = Migration
654 Threshold = "Migration Selection Type = LowestUtil"
655 Job Template = "MigrationTemplate"
658 would select all pools for examination and generate a job based on
659 MigrationTemplate to automatically select the volume with the lowest
660 usage and migrate it's contents to the nextpool defined for that pool.
662 This policy abstraction would be really handy for adjusting the behavior
663 of Bacula according to site-selectable criteria (one thing that pops
664 into mind is Amanda's ability to automatically adjust backup levels
665 depending on various criteria).
671 - Add Pool/Storage override regression test.
672 - Add delete JobId to regression.
673 - Add a regression test for dbcheck.
674 - New test to add bscan to four-concurrent-jobs regression,
675 i.e. after the four-concurrent jobs zap the
676 database as is done in the bscan-test, then use bscan to
677 restore the database, do a restore and compare with the
679 - Add restore of specific JobId to regression (item 3
680 on the restore prompt)
681 - Add IPv6 to regression
682 - Add database test to regression. Test each function like delete,
685 - AntiVir can slow down backups on Win32 systems.
686 - Win32 systems with FAT32 can be much slower than NTFS for
687 more than 1000 files per directory.
691 - A HOLD command to stop all jobs from starting.
692 - A PAUSE command to pause all running jobs ==> release the

695 Media Type Read = LTO,LTO2,LTO3
696 Media Type Write = LTO2, LTO3
698 === From Carsten Menke <bootsy52@gmx.net>
700 Following is a list of what I think in the situations where I'm faced with,
701 could be a usefull enhancement to bacula, which I'm certain other users will
702 benefit from as well.
704 1. NextJob/NextJobs Directive within a Job Resource in the form of
705 NextJobs = job1,job2.
708 I currently solved the problem with running multiple jobs each after each
709 by setting the Max Wait Time for a job to 8 hours, and give
710 the jobs different Priorities. However, there scenarios where
711 1 Job is directly depending on another job, so if the former job fails,
712 the job after it needn't to be run
713 while maybe other jobs should run despite of that
716 A Backup Job and a Verify job, if the backup job fails there is no need to run
717 the verify job, as the backup job already failed. However, one may like
718 to backup the Catalog to disk despite of that the main backup job failed.
721 I see that this is related to the Event Handlers which are on the ToDo
722 list, also it is maybe a good idea to check for the return value and
723 execute different actions based on the return value
726 3. offline capability to bconsole
729 Currently I use a script which I execute within the last Job via the
730 RunAfterJob Directive, to release and eject the tape.
731 So I have to call bconsole "release=Storage-Name" and afterwards
732 mt -f /dev/nst0 eject to get the tape out.
734 If I have multiple Storage Devices, than these may not be /dev/nst0 and
735 I have to modify the script or call it with parameters etc.
736 This would actually not be needed, as everything is already defined
737 in bacula-sd.conf and if I can invoke bconsole with the
738 storage name via $1 in the script than I'm done and information is
741 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
745 For the reason mentioned in 3. to have the ability to call a
746 script with /scripts/foobar %s and in the script use $1
747 to pass the Storage Name to bconsole
749 5. Setting Volume State within a Job Resource
752 Instead of using "Maximum Volume Jobs" in the Pool Resource,
753 I would have the possibilty to define
754 in a Job Resource that after this certain job is run, the Volume State
755 should be set to "Volume State = Used", this give more flexibility (IMHO).
757 6. Localization of Bacula Messages
760 Unfortunatley many,many people I work with don't speak english very well.
761 So if at least the Reporting messages would be localized then they
762 would understand that they have to change the tape,etc. etc.
764 I volunteer to do the german translations, and if I can convince my wife also
765 french and Morre (western african language).
767 7. OK, this is evil, probably bound to security risks and maybe not possible
768 due to the design of bacula.
770 Implementation of Backtics ( `command` ) for shell comand execution to
771 the "Label Format" Directive.
775 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
776 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
777 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
778 the localized name for the day of the week appended to the
779 format string. Then I have the tape labeled automatically with weekday
780 name in the correct language.
782 - Yes, that is surely the case. I probably should turn those into Warning
783 errors. In addition, you just made me think that it might not be bad to
784 add an option to check the file size after backing up the file and
785 report if it changes. This would be done as an option because it would
788 Kern, good idea. If you do do that, mention in the output: file
789 shrunk, or file expanded, just to make it obvious to the user
790 (without having to the refer to file size), just how the file size
793 Would this option be for all file, or just one file? Or a fileset?
794 - Make output from status use html table tags for nicely
795 presenting in a browser.
796 - Can one write tapes faster with 8192 byte block sizes?
797 - Document security problems with the same password for everyone in
798 rpm and Win32 releases.
799 - Browse generations of files.
800 - I've seen an error when my catalog's File table fills up. I
801 then have to recreate the File table with a larger maximum row
802 size. Relevant information is at
803 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
804 "Installing and Configuring MySQL" chapter should talk a bit
805 about this potential problem, and recommend a solution.
806 - For Solaris must use POSIX awk.
807 - Want speed of writing to tape while despooling.
808 - Supported autochanger:
816 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
817 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
818 - Add regex from http://www.pcre.org to Bacula for Win32.
819 - Use only shell tools no make in CDROM package.
820 - Include within include does it work?
821 - Implement a Pool of type Cleaning?
822 - Implement VolReadTime and VolWriteTime in SD
823 - Modify Backing up Your Database to include a bootstrap file.
824 - Think about making certain database errors fatal.
825 - Look at correcting the time jump in the scheduler for daylight
826 savings time changes.
827 - Add a "real" timer to network connections.
828 - Promote to Full = Time period
829 - Check dates entered by user for correctness (month/day/... ranges)
830 - Compress restore Volume listing by date and first file.
831 - Look at patches/bacula_db.b2z postgresql that loops during restore.
833 - Perhaps add read/write programs and/or plugins to FileSets.
834 - How to handle backing up portables ...
835 - Add some sort of guaranteed Interval for upgrading jobs.
836 - Can we write the state file after every job terminates? On Win32
837 the system crashes and the state file is not updated.
840 Documentation to do: (any release a little bit at a time)
841 - Doc to do unmount before removing magazine.
842 - Alternative to static linking "ldd prog" save all binaries listed,
843 restore them and point LD_LIBRARY_PATH to them.
844 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
845 - Document query file format.
846 - Add more documentation for bsr files.
847 - Document problems with Verify and pruning.
848 - Document how to use multiple databases.
849 - VXA drives have a "cleaning required"
850 indicator, but Exabyte recommends preventive cleaning after every 75
853 In this context, it should be noted that Exabyte has a command-line
854 vxatool utility available for free download. (The current version is
855 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
856 test the drive, unload tapes, change drive settings, flash new firmware,
858 Of particular interest in this context is that vxatool <device> -i will
859 report, among other details, the time since last cleaning in tape motion
860 minutes. This information can be retrieved (and settings changed, for
861 that matter) through the generic-SCSI device even when Bacula has the
862 regular tape device locked. (Needless to say, I don't recommend
863 changing tape settings while a job is running.)
864 - Lookup HP cleaning recommendations.
865 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
866 - Document doing table repair
869 ===================================
870 - Add macro expansions in JobDefs.
871 Run Before Job = "SomeFile %{Level} %{Client}"
872 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
873 - Use non-blocking network I/O but if no data is available, use
875 - Use gather write() for network I/O.
876 - Autorestart on crash.
877 - Add bandwidth limiting.
878 - Add acks every once and a while from the SD to keep
879 the line from timing out.
880 - When an error in input occurs and conio beeps, you can back
881 up through the prompt.
882 - Detect fixed tape block mode during positioning by looking at
883 block numbers in btape "test". Possibly adjust in Bacula.
884 - Fix list volumes to output volume retention in some other
885 units, perhaps via a directive.
886 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
887 with multiple priorities.
888 - If you use restore replace=never, the directory attributes for
889 non-existent directories will not be restored properly.
891 - see lzma401.zip in others directory for new compression
893 - Allow the user to select JobType for manual pruning/purging.
894 - bscan does not put first of two volumes back with all info in
896 - Implement the FreeBSD nodump flag in chflags.
897 - Figure out how to make named console messages go only to that
898 console and to the non-restricted console (new console class?).
899 - Make restricted console prompt for password if *ask* is set or
900 perhaps if password is undefined.
901 - Implement "from ISO-date/time every x hours/days/weeks/months" in
904 ==== from Marc Schoechlin
905 - the help-command should be more verbose
906 (it should explain the paramters of the different
908 -> its time-comsuming to consult the manual anytime
909 you need a special parameter
910 -> maybe its more easy to maintain this, if the
911 descriptions of that commands are outsourced to
913 - the cd-command should allow complete paths
914 i.e. cd /foo/bar/foo/bar
915 -> if a customer mails me the path to a certain file,
916 its faster to enter the specified directory
917 - if the password is not configured in bconsole.conf
918 you should be asked for it.
919 -> sometimes you like to do restore on a customer-machine
920 which shouldnt know the password for bacula.
921 -> adding the password to the file favours admins
922 to forget to remove the password after usage
924 the protection of that file is less important
925 - long-listed-output of commands should be scrollable
926 like the unix more/less-command does
927 -> if someone runs 200 and more machines, the lists could
928 be a little long and complex
929 - command-output should be shown column by column
930 to reduce scrolling and to increase clarity
932 - lsmark should list the selected files with full
934 - wildcards for selecting and file and directories would be nice
935 - any actions should be interuptable with STRG+C
936 - command-expansion would be pretty cool
938 - When the replace Never option is set, new directory permissions
939 are not restored. See bug 213. To fix this requires creating a
940 list of newly restored directories so that those directory
941 permissions *can* be restored.
942 - Add prune all command
943 - Document fact that purge can destroy a part of a restore by purging
944 one volume while others remain valid -- perhaps mark Jobs.
945 - Add multiple-media-types.txt
946 - look at mxt-changer.html
947 - Make ? do a help command (no return needed).
948 - Implement restore directory.
949 - Document streams and how to implement them.
950 - Try not to re-backup a file if a new hard link is added.
951 - Add feature to backup hard links only, but not the data.
952 - Fix stream handling to be simpler.
953 - Add Priority and Bootstrap to Run a Job.
954 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
956 - Remove View FileSet button from Run a Job dialog.
957 - Handle prompt for restore job at end of Restore command.
958 - Add display of total selected files to Restore window.
959 - Add tree pane to left of window.
960 - Add progress meter.
961 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
962 - Add message to user to check for fixed block size when the forward
963 space test fails in btape.
964 - When unmarking a directory check if all files below are unmarked and
965 then remove the + flag -- in the restore tree.
966 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
967 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
968 - Revisit the question of multiple Volumes (disk) on a single device.
969 - Add a block copy option to bcopy.
970 - Finish work on Gnome restore GUI.
971 - Fix "llist jobid=xx" where no fileset or client exists.
972 - For each job type (Admin, Restore, ...) require only the really necessary
973 fields.- Pass Director resource name as an option to the Console.
974 - Add a "batch" mode to the Console (no unsolicited queries, ...).
975 - Add a .list all files in the restore tree (probably also a list all files)
976 Do both a long and short form.
977 - Allow browsing the catalog to see all versions of a file (with
978 stat data on each file).
979 - Restore attributes of directory if replace=never set but directory
981 - Use SHA1 on authentication if possible.
982 - See comtest-xxx.zip for Windows code to talk to USB.
983 - Add John's appended files:
984 Appended = { /files/server/logs/http/*log }
985 and such files would be treated as follows.On a FULL backup, they would
986 be backed up like any other file.On an INCREMENTAL backup, where a
987 previous INCREMENTAL or FULL was already in thecatalogue and the length
988 of the file wasgreater than the length of the last backup, only thedata
989 added since the last backup will be dumped.On an INCREMENTAL backup, if
990 the length of the file is less than thelength of the file with the same
991 name last backed up, the completefile is dumped.On Windows systems, with
992 creation date of files, we can be evensmarter about this and not count
993 entirely upon the length.On a restore, the full and all incrementals
994 since it will beapplied in sequence to restore the file.
995 - Check new HAVE_WIN32 open bits.
996 - Check if the tape has moved before writing.
997 - Handling removable disks -- see below:
998 - Keep track of tape use time, and report when cleaning is necessary.
999 - Add FromClient and ToClient keywords on restore command (or
1000 BackupClient RestoreClient).
1001 - Implement a JobSet, which groups any number of jobs. If the
1002 JobSet is started, all the jobs are started together.
1003 Allow Pool, Level, and Schedule overrides.
1004 - Enhance cancel to timeout BSOCK packets after a specific delay.
1005 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1006 ua_status.!!! Thanks to Alan Brown for this tip.
1007 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1008 correctly for multiple simultaneous jobs.
1009 - Correct code so that FileSet MD5 is calculated for < and | filename
1011 - Implement the Media record flag that indicates that the Volume does disk
1013 - Implement VolAddr, which is used when Volume is addressed like a disk,
1014 and form it from VolFile and VolBlock.
1015 - Make multiple restore jobs for multiple media types specifying
1016 the proper storage type.
1017 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1018 pointer (rec) to try_repositioning().
1019 - Look at extracting Win data from BackupRead.
1020 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1021 which would take precidence over the Catalog "JobRetention".
1022 - Implement Label Format in Add and Label console commands.
1023 - Possibly up network buffers to 65K. Put on variable.
1024 - Put email tape request delays on one or more variables. User wants
1025 to cancel the job after a certain time interval. Maximum Mount Wait?
1026 - Job, Client, Device, Pool, or Volume?
1027 Is it possible to make this a directive which is *optional* in multiple
1028 resources, like Level? If so, I think I'd make it an optional directive
1029 in Job, Client, and Pool, with precedence such that Job overrides Client
1030 which in turn overrides Pool.
1032 - New Storage specifications:
1033 - Want to write to multiple storage devices simultaneously
1034 - Want to write to multiple storage devices sequentially (in one job)
1035 - Want to read/write simultaneously
1036 - Key is MediaType -- it must match
1038 Passed to SD as a sort of BSR record called Storage Specification
1042 MediaType -> Next MediaType
1044 Device -> Next Device
1046 Allow multiple Storage specifications
1054 Allow Multiple Pool specifications (note, Pool currently
1056 Allow Multiple MediaType specifications in Dir conf
1057 Allow Multiple Device specifications in Dir conf
1058 Perhaps keep this in a single SSR
1059 Tie a Volume to a specific device by using a MediaType that
1060 is contained in only one device.
1061 In SD allow Device to have Multiple MediaTypes
1063 - Ideas from Jerry Scharf:
1064 First let's point out some big pluses that bacula has for this
1066 more importantly it's active. Thank you so much for that
1067 even more important, it's not flaky
1068 it has an open access catalog, opening many possibilities
1069 it's pushing toward heterogeneous systems capability
1071 Macintosh file client
1072 macs are an interesting niche, but I fear a server is a rathole
1073 working bare iron recovery for windows
1074 the option for inc/diff backups not reset on fileset revision
1075 a) use both change and inode update time against base time
1076 b) do the full catalog check (expensive but accurate)
1077 sizing guide (how much system is needed to back up N systems/files)
1078 consultants on using bacula in building a disaster recovery system
1079 an integration guide
1080 or how to get at fancy things that one could do with bacula
1081 logwatch code for bacula logs (or similar)
1082 linux distro inclusion of bacula (brings good and bad, but necessary)
1083 win2k/XP server capability (icky but you asked)
1084 support for Oracle database ??
1086 - Look at adding SQL server and Exchange support for Windows.
1087 - Make dev->file and dev->block_num signed integers so that -1 can
1088 be an invalid value which happens with BSR.
1089 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1090 is needed to properly specify ranges.
1091 - Add progress of files/bytes to SD and FD.
1092 - Print warning message if FileId > 4 billion
1093 - do a "messages" before the first prompt in Console
1094 - Client does not show busy during Estimate command.
1095 - Implement Console mtx commands.
1096 - Implement a Mount Command and an Unmount Command where
1097 the users could specify a system command to be performed
1098 to do the mount, after which Bacula could attempt to
1099 read the device. This is for Removeable media such as a CDROM.
1100 - Most likely, this mount command would be invoked explicitly
1101 by the user using the current Console "mount" and "unmount"
1102 commands -- the Storage Daemon would do the right thing
1103 depending on the exact nature of the device.
1104 - As with tape drives, when Bacula wanted a new removable
1105 disk mounted, it would unmount the old one, and send a message
1106 to the user, who would then use "mount" as described above
1107 once he had actually inserted the disk.
1108 - Implement dump/print label to UA
1109 - Spool to disk only when the tape is full, then when a tape is hung move
1111 - bextract is sending everything to the log file ****FIXME****
1112 - Allow multiple Storage specifications (or multiple names on
1113 a single Storage specification) in the Job record. Thus a job
1114 can be backed up to a number of storage devices.
1115 - Implement some way for the File daemon to contact the Director
1116 to start a job or pass its DHCP obtained IP number.
1117 - Implement a query tape prompt/replace feature for a console
1118 - Copy console @ code to gnome2-console
1119 - Make tree walk routines like cd, ls, ... more user friendly
1120 by handling spaces better.
1121 - Make sure that Bacula rechecks the tape after the 20 min wait.
1122 - Set IO_NOWAIT on Bacula TCP/IP packets.
1123 - Try doing a raw partition backup and restore by mounting a
1125 - From Lars Kellers:
1126 Yes, it would allow to highly automatic the request for new tapes. If a
1127 tape is empty, bacula reads the barcodes (native or simulated), and if
1128 an unused tape is found, it runs the label command with all the
1129 necessary parameters.
1131 By the way can bacula automatically "move" an empty/purged volume say
1132 in the "short" pool to the "long" pool if this pool runs out of volume
1134 - What to do about "list files job=xxx".
1135 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1136 file descriptor leak in Bacula.
1137 - Implement WrapCounters in Counters.
1138 - Add heartbeat from FD to SD if hb interval expires.
1139 - Can we dynamically change FileSets?
1140 - If pool specified to label command and Label Format is specified,
1141 automatically generate the Volume name.
1142 - Why can't SQL do the filename sort for restore?
1143 - Add ExhautiveRestoreSearch
1144 - Look at the possibility of loading only the necessary
1145 data into the restore tree (i.e. do it one directory at a
1146 time as the user walks through the tree).
1147 - Possibly use the hash code if the user selects all for a restore command.
1148 - Fix "restore all" to bypass building the tree.
1149 - Prohibit backing up archive device (findlib/find_one.c:128)
1150 - Implement Release Device in the Job resource to unmount a drive.
1151 - Implement Acquire Device in the Job resource to mount a drive,
1152 be sure this works with admin jobs so that the user can get
1153 prompted to insert the correct tape. Possibly some way to say to
1154 run the job but don't save the files.
1155 - Make things like list where a file is saved case independent for
1157 - Use autochanger to handle multiple devices.
1158 - Implement a Recycle command
1159 - Start working on Base jobs.
1160 - Implement UnsavedFiles DB record.
1161 - From Phil Stracchino:
1162 It would probably be a per-client option, and would be called
1163 something like, say, "Automatically purge obsoleted jobs". What it
1164 would do is, when you successfully complete a Differential backup of a
1165 client, it would automatically purge all Incremental backups for that
1166 client that are rendered redundant by that Differential. Likewise,
1167 when a Full backup on a client completed, it would automatically purge
1168 all Differential and Incremental jobs obsoleted by that Full backup.
1169 This would let people minimize the number of tapes they're keeping on
1170 hand without having to master the art of retention times.
1171 - When doing a Backup send all attributes back to the Director, who
1172 would then figure out what files have been deleted.
1173 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1174 explicit permission to do so. It should also mark the tape in error
1175 if there is an error.
1176 - Cancel waiting for Client connect in SD if FD goes away.
1178 - Implement timeout in response() when it should come quickly.
1179 - Implement a Slot priority (loaded/not loaded).
1180 - Implement "vacation" Incremental only saves.
1181 - Implement create "FileSet"?
1182 - Add prefixlinks to where or not where absolute links to FD.
1183 - Issue message to mount a new tape before the rewind.
1184 - Simplified client job initiation for portables.
1185 - If SD cannot open a drive, make it periodically retry.
1186 - Add more of the config info to the tape label.
1188 - Refine SD waiting output:
1189 Device is being positioned
1190 > Device is being positioned for append
1191 > Device is being positioned to file x
1193 - Figure out some way to estimate output size and to avoid splitting
1194 a backup across two Volumes -- this could be useful for writing CDROMs
1195 where you really prefer not to have it split -- not serious.
1196 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1197 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1198 actual data on the Volume and compare it.
1199 - Implement Bacula plugins -- design API
1200 - Make bcopy read through bad tape records.
1201 - Program files (i.e. execute a program to read/write files).
1202 Pass read date of last backup, size of file last time.
1203 - Add Signature type to File DB record.
1204 - CD into subdirectory when open()ing files for backup to
1205 speed up things. Test with testfind().
1206 - Priority job to go to top of list.
1207 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1208 - Implement some way for the Console to dynamically create a job.
1209 - Solaris -I on tar for include list
1210 - Need a verbose mode in restore, perhaps to bsr.
1211 - bscan without -v is too quiet -- perhaps show jobs.
1212 - Add code to reject whole blocks if not wanted on restore.
1213 - Check if we can increase Bacula FD priorty in Win2000
1214 - Make sure the MaxVolFiles is fully implemented in SD
1215 - Check if both CatalogFiles and UseCatalog are set to SD.
1216 - Possibly add email to Watchdog if drive is unmounted too
1217 long and a job is waiting on the drive.
1218 - After unmount, if restore job started, ask to mount.
1219 - Add UA rc and history files.
1220 - put termcap (used by console) in ./configure and
1221 allow -with-termcap-dir.
1222 - Fix Autoprune for Volumes to respect need for full save.
1223 - Compare tape to Client files (attributes, or attributes and data)
1224 - Make all database Ids 64 bit.
1225 - Allow console commands to detach or run in background.
1226 - Add SD message variables to control operator wait time
1227 - Maximum Operator Wait
1228 - Minimum Message Interval
1229 - Maximum Message Interval
1230 - Send Operator message when cannot read tape label.
1231 - Verify level=Volume (scan only), level=Data (compare of data to file).
1232 Verify level=Catalog, level=InitCatalog
1234 - Add keyword search to show command in Console.
1235 - Events : tape has more than xxx bytes.
1236 - Complete code in Bacula Resources -- this will permit
1237 reading a new config file at any time.
1238 - Handle ctl-c in Console
1239 - Implement script driven addition of File daemon to config files.
1240 - Think about how to make Bacula work better with File (non-tape) archives.
1241 - Write Unix emulator for Windows.
1242 - Put memory utilization in Status output of each daemon
1243 if full status requested or if some level of debug on.
1244 - Make database type selectable by .conf files i.e. at runtime
1245 - Set flag for uname -a. Add to Volume label.
1246 - Restore files modified after date
1247 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1248 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1249 - Timout a job or terminate if link goes down, or reopen link and query.
1250 - Concept of precious tapes (cannot be reused).
1251 - Make bcopy copy with a single tape drive.
1252 - Permit changing ownership during restore.

1266 - Autolabel should be specified by DIR instead of SD.
1268 - Add media capacity
1269 - AutoScan (check checksum of tape)
1270 - Format command = "format /dev/nst0"
1274 - Seek resolution (usually corresponds to buffer size)
1275 - EODErrorCode=ENOSPC or code
1276 - Partial Read error code
1277 - Partial write error code
1278 - Nonformatted read error
1279 - Nonformatted write error
1280 - WriteProtected error
1284 - IgnoreCloseErrors=yes
1294 - FD sends unsaved file list to Director at end of job (see
1296 - File daemon should build list of files skipped, and then
1297 at end of save retry and report any errors.
1298 - Write a Storage daemon that uses pipes and
1299 standard Unix programs to write to the tape.
1301 - Need something that monitors the JCR queue and
1302 times out jobs by asking the deamons where they are.
1303 - Enhance Jmsg code to permit buffering and saving to disk.
1304 - device driver = "xxxx" for drives.
1305 - Verify from Volume
1306 - Ensure that /dev/null works
1307 - Need report class for messages. Perhaps
1308 report resource where report=group of messages
1309 - enhance scan_attrib and rename scan_jobtype, and
1310 fill in code for "since" option
1311 - Director needs a time after which the report status is sent
1312 anyway -- or better yet, a retry time for the job.
1313 - Don't reschedule a job if previous incarnation is still running.
1314 - Some way to automatically backup everything is needed????
1315 - Need a structure for pending actions:
1317 - termination status (part of buffered msgs?)
1319 Read, Write, Clean, Delete
1320 - Login to Bacula; Bacula users with different permissions:
1321 owner, group, user, quotas
1322 - Store info on each file system type (probably in the job header on tape.
1323 This could be the output of df; or perhaps some sort of /etc/mtab record.

1326 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1327 To: <kern@sibbald.com>
1328 Subject: RE: [Bacula-users] future large programming jobs
1329 Date: Thu, 26 Feb 2004 11:34:54 -0600
1331 I noticed the subject thread and thought I would offer the following
1332 merely as sources of ideas, i.e. something to think about, not even as
1333 strong as a request. In my former life (before retiring) I often
1334 dealt with backups and storage management issues/products as a
1335 developer and as a consultant. I am currently migrating my personal
1336 network from amanda to bacula specifically because of the ability to
1337 cross media boundaries during storing backups.
1338 Are you familiar with the commercial product called ADSM (I think IBM
1339 now sells it under the Tivoli label)? It has a couple of interesting
1340 ideas that may apply to the following topics.
1342 1. Migration: Consider that when you need to restore a system, there
1343 may be pressure to hurry. If all the information for a single client
1344 can eventually end up on the same media (and in chronological order),
1345 the restore is facillitated by not having to search past information
1346 from other clients. ADSM has the concept of "client affinity" that
1347 may be associated with it's storage pools. It seems to me that this
1348 concept (as an optional feature) might fit in your architecture for
1351 ADSM also has the concept of defining one or more storage pools as
1352 "copy pools" (almost mirrors, but only in the sense of contents).
1353 These pools provide the ability to have duplicte data stored both
1354 onsite and offsite. The copy process can be scheduled to be handled
1355 by their storage manager during periods when there is no backup
1356 activity. Again, the migration process might be a place to consider
1357 implementing something like this.
1360 > It strikes me that it would be very nice to be able to do things
1362 > have the Job(s) backing up the machines run, and once they have all

1368 > mechanism described below would probably make it very easy.
1370 This is the goal. In the first step (before events), you simply
1372 the Migration to tape later.
1374 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1375 the database. Once a file (unique by path and metadata such as dates,
1376 size, ownership, etc.) is in a copy pool, no more copies are made. In
1377 other words, when you start ADSM, it begins like your concept of a
1378 base job. After that it is in the "incremental" mode. You can
1379 configure the number of "generations" of files to be retained, plus a
1380 retention date after which even old generations are purged. The
1381 database tracks the contents of media and projects the percentage of
1382 each volume that is valid. When the valid content of a volume drops
1383 below a configured percentage, the valid data are migrated to another
1384 volume and the old volume is marked as empty. Note, this requires
1385 ADSM to have an idea of the contents of a client, i.e. marking the
1386 database when an existing file was deleted, but this would solve your
1387 issue of restoring a client without restoring deleted files.
1389 This is pretty far from what bacula now does, but if you are going to
1390 rip things up for Base jobs,.....
1391 Also, the benefits of this are huge for very large shops, especially
1392 with media robots, but are a pain for shops with manual media
1396 > Base jobs sound pretty useful, but I'm not dying for them.
1398 Nobody is dying for them, but when you see what it does, you will die
1401 3. Restoring deleted files: Since I think my comments in (2) above
1402 have low probability of implementation, I'll also suggest that you
1403 could approach the issue of deleted files by a mechanism of having the
1404 fd report to the dir, a list of all files on the client for every
1405 backup job. The dir could note in the database entry for each file
1406 the date that the file was seen. Then if a restore as of date X takes
1407 place, only files that exist from before X until after X would be
1408 restored. Probably the major cost here is the extra date container in
1409 each row of the files table.
1411 Thanks for "listening". I hope some of this helps. If you want to
1412 contact me, please send me an email - I read some but not all of the
1413 mailing list traffic and might miss a reply there.
1415 Please accept my compliments for bacula. It is doing a great job for
1416 me!! I sympathize with you in the need to wrestle with excelence in
1417 execution vs. excelence in feature inclusion.
1422 ==============================
1425 - Design at hierarchial storage for Bacula. Migration and Clone.
1426 - Implement FSM (File System Modules).
1427 - Audit M_ error codes to ensure they are correct and consistent.
1428 - Add variable break characters to lex analyzer.
1429 Either a bit mask or a string of chars so that
1430 the caller can change the break characters.
1431 - Make a single T_BREAK to replace T_COMMA, etc.
1432 - Ensure that File daemon and Storage daemon can
1433 continue a save if the Director goes down (this
1434 is NOT currently the case). Must detect socket error,
1435 buffer messages for later.
1436 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1437 - Add ability to backup to two Storage devices (two SD sessions) at
1438 the same time -- e.g. onsite, offsite.
1439 - Add the ability to consolidate old backup sets (basically do a restore
1440 to tape and appropriately update the catalog). Compress Volume sets.
1441 Might need to spool via file is only one drive is available.
1442 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1443 someway to do so with every volume that has less than x% valid
1447 Migration: Move a backup from one Volume to another
1448 Clone: Copy a backup -- two Volumes
1451 ======================================================
1453 It is somewhat like a Full save becomes an incremental since
1454 the Base job (or jobs) plus other non-base files.
1456 - A Base backup is same as Full backup, just different type.
1457 - New BaseFiles table that contains:
1459 BaseJobId - Base JobId referenced for this FileId (needed ???)
1460 JobId - JobId currently running
1461 FileId - File not backed up, exists in Base Job
1462 FileIndex - FileIndex from Base Job.
1463 i.e. for each base file that exists but is not saved because
1464 it has not changed, the File daemon sends the JobId, BaseId,
1465 FileId, FileIndex back to the Director who creates the DB entry.
1466 - To initiate a Base save, the Director sends the FD
1467 the FileId, and full filename for each file in the Base.
1468 - When the FD finds a Base file, he requests the Director to
1469 send him the full File entry (stat packet plus MD5), or
1470 conversely, the FD sends it to the Director and the Director
1471 says yes or no. This can be quite rapid if the FileId is kept
1472 by the FD for each Base Filename.
1473 - It is probably better to have the comparison done by the FD
1474 despite the fact that the File entry must be sent across the
1476 - An alternative would be to send the FD the whole File entry
1477 from the start. The disadvantage is that it requires a lot of
1478 space. The advantage is that it requires less communications
1480 - The Job record must be updated to indicate that one or more
1482 - At end of Job, FD returns:
1483 1. Count of base files/bytes not written to tape (i.e. matches)
1484 2. Count of base file that were saved i.e. had changed.
1485 - No tape record would be written for a Base file that matches, in the
1486 same way that no tape record is written for Incremental jobs where
1487 the file is not saved because it is unchanged.
1488 - On a restore, all the Base file records must explicitly be
1489 found from the BaseFile tape. I.e. for each Full save that is marked
1490 to have one or more Base Jobs, search the BaseFile for all occurrences
1492 - An optimization might be to make the BaseFile have:
1498 This would avoid the need to explicitly fetch each File record for
1499 the Base job. The Base Job record will be fetched to get the
1500 VolSessionId and VolSessionTime.
1501 =========================================================
1504 ==========================================================
1506 For each Incremental job that is run, there may be files that
1507 were found but not saved because they were locked (this applies
1508 only to Windows). Such a system could send back to the Director
1509 a list of Unsaved files.
1511 - New UnSavedFiles table that contains:
1515 - Then in the next Incremental job, the list of Unsaved Files will be
1516 feed to the FD, who will ensure that they are explicitly chosen even
1517 if standard date/time check would not have selected them.
1518 =============================================================

1559 (just to verify it remembers where it came from, however it can be

1562 There needs to be a table of drive # to devices somewhere - If there are
1563 multiple changers or drives there may not be a 1:1 correspondance between
1564 changer drive number and system device name - and depending on the way the
1565 drives are hooked up to scsi busses, they may not be linearly numbered
1566 from an offset point either.something like
1568 Autochanger drives = 2
1569 Autochanger drive 0 = /dev/nst1
1570 Autochanger drive 1 = /dev/nst2
1571 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1572 times, not just for multidrive changers. For a 1 drive changer, that's
1578 MTX's manpage (1.2.15):
1579 unload [<slotnum>] [ <drivenum> ]
1580 Unloads media from drive <drivenum> into slot
1581 <slotnum>. If <drivenum> is omitted, defaults to
1582 drive 0 (as do all commands). If <slotnum> is
1583 omitted, defaults to the slot that the drive was
1584 loaded from. Note that there's currently no way
1585 to say 'unload drive 1's media to the slot it
1586 came from', other than to explicitly use that
1587 slot number as the destination.AB

1625 Handling removable disks
1627 From: Karl Cunningham <karlc@keckec.com>
1629 My backups are only to hard disk these days, in removable bays. This is my
1630 idea of how a backup to hard disk would work more smoothly. Some of these
1631 things Bacula does already, but I mention them for completeness. If others
1632 have better ways to do this, I'd like to hear about it.
1634 1. Accommodate several disks, rotated similar to how tapes are. Identified
1635 by partition volume ID or perhaps by the name of a subdirectory.
1636 2. Abort & notify the admin if the wrong disk is in the bay.
1637 3. Write backups to different subdirectories for each machine to be backed
1639 4. Volumes (files) get created as needed in the proper subdirectory, one
1641 5. When a disk is recycled, remove or zero all old backup files. This is
1642 important as the disk being recycled may be close to full. This may be
1643 better done manually since the backup files for many machines may be
1644 scattered in many subdirectories.
1649 - Make sure that all do_prompt() calls in Dir check for
1650 -1 (error) and -2 (cancel) returns.
1651 - Fix foreach_jcr() to have free_jcr() inside next().
1652 jcr=jcr_walk_start();
1653 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1656 - A Volume taken from Scratch should take on the retention period
1658 - Correct doc for Maximum Changer Wait (and others) accepting only
1660 - Implement status that shows why a job is being held in reserve, or
1661 rather why none of the drives are suitable.
1662 - Implement a way to disable a drive (so you can use the second
1663 drive of an autochanger, and the first one will not be used or
1665 - Make sure Maximum Volumes is respected in Pools when adding
1666 Volumes (e.g. when pulling a Scratch volume).
1667 - Keep same dcr when switching device ...
1668 - Implement code that makes the Dir aware that a drive is an
1669 autochanger (so the user doesn't need to use the Autochanger = yes
1671 - Make catalog respect ACL.
1672 - Add recycle count to Media record.
1673 - Add initial write date to Media record.
1674 - Fix store_yesno to be store_bitmask.
