17 - During tests with the 260 char fix code, I found one problem:
18 if the system "sees" a long path once, it seems to forget it's
19 working drive (e.g. c:\), which will lead to a problem during
20 the next job (create bootstrap file will fail). Here is the
21 workaround: specify absolute working and pid directory in

142 better machine-readable output like "Ok" or "Error busy"
143 .move eject device=xxx toslot=yyy the same as above, but with a new
144 target slot. The catalog should be updated accordingly.

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

230 order by Path.Path ASC;
232 - Look into using Dart for testing

238 === Migration from David ===
239 What I'd like to see:
242 Name = "<poolname>-migrate"
246 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
247 Client | PoolResidence | Volume | JobName | SQLquery
248 Migration Selection Pattern = "regexp"
249 Next Pool = <override>
252 There should be no need for a Level (migration is always Full, since you
253 don't calculate differential/incremental differences for migration),
254 Storage should be determined by the volume types in the pool, and Client
255 is really a selection issue. Migration should always occur to the
256 NextPool defined in the pool definition. If no nextpool is defined, the
257 job should end with a reason of "no place to go". If Next Pool statement
258 is present, we override the check in the pool definition and use the
261 Here's how I'd define Migration Selection Types:
264 Client -- Migrate data from selected client only. Migration Selection
265 Pattern regexp provides pattern to select client names, eg ^FS00* makes
266 all client names starting with FS00 eligible for migration.
268 Jobname -- Migration all jobs matching name. Migration Selection Pattern
269 regexp provides pattern to select jobnames existing in pool.
271 Volume -- Migrate all data on specified volumes. Migration Selection
272 Pattern regexp provides selection criteria for volumes to be migrated.
273 Volumes must exist in pool to be eligible for migration.
277 LowestUtil -- Identify the volume in the pool with the least data on it
278 and empty it. No Migration Selection Pattern required.
280 OldestVol -- Identify the LRU volume with data written, and empty it. No
281 Migration Selection Pattern required.
283 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
284 (starting with most full volumes) until pool occupancy drops below
285 <lowmig>. Pool highmig and lowmig values are in pool definition, no
286 Migration Selection Pattern required.
290 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
291 Migration Selection Pattern contains SQL query to execute; should return
292 a list of 1 or more jobuids to migrate.
294 PoolResidence -- Migrate data sitting in pool for longer than
295 PoolResidence value in pool definition. Migration Selection Pattern
296 optional; if specified, override value in pool definition (value in

474 1. When jobs are running and bacula for some reason crashes or if I do a
475 restart it remembers and jobs it was running before it crashed or restarted
476 as of now I loose all jobs if I restart it.
478 2. When spooling and in the midway if client is disconnected for instance a
479 laptop bacula completely discard the spool. It will be nice if it can write
480 that spool to tape so there will be some backups for that client if not all.
482 3. We have around 150 clients machines it will be nice to have a option to
483 upgrade all the client machines bacula version automatically.
485 4. Atleast one connection should be reserved for the bconsole so at heavy load
486 I should connect to the director via bconsole which at sometimes I can't
488 5. Another most important feature that is missing, say at 10am I manually
489 started backup of client abc and it was a full backup since client abc has
490 no backup history and at 10.30am bacula again automatically started backup of
491 client abc as that was in the schedule. So now we have 2 multiple Full
492 backups of the same client and if we again try to start a full backup of
493 client backup abc bacula won't complain. That should be fixed.
495 - Fix bpipe.c so that it does not modify results pointer.
496 ***FIXME*** calling sequence should be changed.
497 - For Windows disaster recovery see http://unattended.sf.net/
498 - regardless of the retention period, Bacula will not prune the
499 last Full, Diff, or Inc File data until a month after the
500 retention period for the last Full backup that was done.
501 - update volume=xxx --- add status=Full
502 - Remove old spool files on startup.
503 - Exclude SD spool/working directory.
504 - Refuse to prune last valid Full backup. Same goes for Catalog.
506 - Make a callback when Rerun failed levels is called.
507 - Give Python program access to Scheduled jobs.
508 - Add setting Volume State via Python.
509 - Python script to save with Python, not save, save with Bacula.
510 - Python script to do backup.
512 - Change the Priority, Client, Storage, JobStatus (error)
513 at the start of a job.
514 - Why is SpoolDirectory = /home/bacula/spool; not reported
515 as an error when writing a DVD?
516 - Make bootstrap file handle multiple MediaTypes (SD)
517 - Remove all old Device resource code in Dir and code to pass it
518 back in SD -- better, rework it to pass back device statistics.
519 - Check locking of resources -- be sure to lock devices where previously
520 resources were locked.
521 - The last part is left in the spool dir.
524 - In restore don't compare byte count on a raw device -- directory
525 entry does not contain bytes.
529 MA = (last_MA * 3 + rate) / 4
530 rate = (bytes - last_bytes) / (runtime - last_runtime)
531 - Max Vols limit in Pool off by one?
532 - Implement Files/Bytes,... stats for restore job.
533 - Implement Total Bytes Written, ... for restore job.
534 - Despool attributes simultaneously with data in a separate
535 thread, rejoined at end of data spooling.
536 - 7. Implement new Console commands to allow offlining/reserving drives,
537 and possibly manipulating the autochanger (much asked for).
538 - Add start/end date editing in messages (%t %T, %e?) ...
539 - Add ClientDefs similar to JobDefs.
540 - Print more info when bextract -p accepts a bad block.
541 - Fix FD JobType to be set before RunBeforeJob in FD.
542 - Look at adding full Volume and Pool information to a Volume
543 label so that bscan can get *all* the info.
544 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
545 and there is only one volume in the pool, refuse to do it -- otherwise
546 he fills the Volume, then immediately starts reusing it.
547 - Implement copies and stripes.
548 - Add history file to console.
549 - Each file on tape creates a JobMedia record. Peter has 4 million
550 files spread over 10000 tape files and four tapes. A restore takes
551 16 hours to build the restore list.
552 - Add and option to check if the file size changed during backup.
553 - Make sure SD deletes spool files on error exit.
554 - Delete old spool files when SD starts.
555 - When labeling tapes, if you enter 000026, Bacula uses
556 the tape index rather than the Volume name 000026.
557 - Add offline tape command to Bacula console.
559 Enter MediaId or Volume name: 32
560 Enter new Volume name: DLT-20Dec04

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

716 Media Type Read = LTO,LTO2,LTO3
717 Media Type Write = LTO2, LTO3
719 === From Carsten Menke <bootsy52@gmx.net>
721 Following is a list of what I think in the situations where I'm faced with,
722 could be a usefull enhancement to bacula, which I'm certain other users will
723 benefit from as well.
725 1. NextJob/NextJobs Directive within a Job Resource in the form of
726 NextJobs = job1,job2.
729 I currently solved the problem with running multiple jobs each after each
730 by setting the Max Wait Time for a job to 8 hours, and give
731 the jobs different Priorities. However, there scenarios where
732 1 Job is directly depending on another job, so if the former job fails,
733 the job after it needn't to be run
734 while maybe other jobs should run despite of that
737 A Backup Job and a Verify job, if the backup job fails there is no need to run
738 the verify job, as the backup job already failed. However, one may like
739 to backup the Catalog to disk despite of that the main backup job failed.
742 I see that this is related to the Event Handlers which are on the ToDo
743 list, also it is maybe a good idea to check for the return value and
744 execute different actions based on the return value
747 3. offline capability to bconsole
750 Currently I use a script which I execute within the last Job via the
751 RunAfterJob Directive, to release and eject the tape.
752 So I have to call bconsole "release=Storage-Name" and afterwards
753 mt -f /dev/nst0 eject to get the tape out.
755 If I have multiple Storage Devices, than these may not be /dev/nst0 and
756 I have to modify the script or call it with parameters etc.
757 This would actually not be needed, as everything is already defined
758 in bacula-sd.conf and if I can invoke bconsole with the
759 storage name via $1 in the script than I'm done and information is
762 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
766 For the reason mentioned in 3. to have the ability to call a
767 script with /scripts/foobar %s and in the script use $1
768 to pass the Storage Name to bconsole
770 5. Setting Volume State within a Job Resource
773 Instead of using "Maximum Volume Jobs" in the Pool Resource,
774 I would have the possibilty to define
775 in a Job Resource that after this certain job is run, the Volume State
776 should be set to "Volume State = Used", this give more flexibility (IMHO).
778 6. Localization of Bacula Messages
781 Unfortunatley many,many people I work with don't speak english very well.
782 So if at least the Reporting messages would be localized then they
783 would understand that they have to change the tape,etc. etc.
785 I volunteer to do the german translations, and if I can convince my wife also
786 french and Morre (western african language).
788 7. OK, this is evil, probably bound to security risks and maybe not possible
789 due to the design of bacula.
791 Implementation of Backtics ( `command` ) for shell comand execution to
792 the "Label Format" Directive.
796 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
797 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
798 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
799 the localized name for the day of the week appended to the
800 format string. Then I have the tape labeled automatically with weekday
801 name in the correct language.
803 - Yes, that is surely the case. I probably should turn those into Warning
804 errors. In addition, you just made me think that it might not be bad to
805 add an option to check the file size after backing up the file and
806 report if it changes. This would be done as an option because it would
809 Kern, good idea. If you do do that, mention in the output: file
810 shrunk, or file expanded, just to make it obvious to the user
811 (without having to the refer to file size), just how the file size
814 Would this option be for all file, or just one file? Or a fileset?
815 - Make output from status use html table tags for nicely
816 presenting in a browser.
817 - Can one write tapes faster with 8192 byte block sizes?
818 - Document security problems with the same password for everyone in
819 rpm and Win32 releases.
820 - Browse generations of files.
821 - I've seen an error when my catalog's File table fills up. I
822 then have to recreate the File table with a larger maximum row
823 size. Relevant information is at
824 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
825 "Installing and Configuring MySQL" chapter should talk a bit
826 about this potential problem, and recommend a solution.
827 - For Solaris must use POSIX awk.
828 - Want speed of writing to tape while despooling.
829 - Supported autochanger:
837 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
838 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
839 - Add regex from http://www.pcre.org to Bacula for Win32.
840 - Use only shell tools no make in CDROM package.
841 - Include within include does it work?
842 - Implement a Pool of type Cleaning?
843 - Implement VolReadTime and VolWriteTime in SD
844 - Modify Backing up Your Database to include a bootstrap file.
845 - Think about making certain database errors fatal.
846 - Look at correcting the time jump in the scheduler for daylight
847 savings time changes.
848 - Add a "real" timer to network connections.
849 - Promote to Full = Time period
850 - Check dates entered by user for correctness (month/day/... ranges)
851 - Compress restore Volume listing by date and first file.
852 - Look at patches/bacula_db.b2z postgresql that loops during restore.
854 - Perhaps add read/write programs and/or plugins to FileSets.
855 - How to handle backing up portables ...
856 - Add some sort of guaranteed Interval for upgrading jobs.
857 - Can we write the state file after every job terminates? On Win32
858 the system crashes and the state file is not updated.
861 Documentation to do: (any release a little bit at a time)
862 - Doc to do unmount before removing magazine.
863 - Alternative to static linking "ldd prog" save all binaries listed,
864 restore them and point LD_LIBRARY_PATH to them.
865 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
866 - Document query file format.
867 - Add more documentation for bsr files.
868 - Document problems with Verify and pruning.
869 - Document how to use multiple databases.
870 - VXA drives have a "cleaning required"
871 indicator, but Exabyte recommends preventive cleaning after every 75
874 In this context, it should be noted that Exabyte has a command-line
875 vxatool utility available for free download. (The current version is
876 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
877 test the drive, unload tapes, change drive settings, flash new firmware,
879 Of particular interest in this context is that vxatool <device> -i will
880 report, among other details, the time since last cleaning in tape motion
881 minutes. This information can be retrieved (and settings changed, for
882 that matter) through the generic-SCSI device even when Bacula has the
883 regular tape device locked. (Needless to say, I don't recommend
884 changing tape settings while a job is running.)
885 - Lookup HP cleaning recommendations.
886 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
887 - Document doing table repair
890 ===================================
891 - Add macro expansions in JobDefs.
892 Run Before Job = "SomeFile %{Level} %{Client}"
893 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
894 - Use non-blocking network I/O but if no data is available, use
896 - Use gather write() for network I/O.
897 - Autorestart on crash.
898 - Add bandwidth limiting.
899 - Add acks every once and a while from the SD to keep
900 the line from timing out.
901 - When an error in input occurs and conio beeps, you can back
902 up through the prompt.
903 - Detect fixed tape block mode during positioning by looking at
904 block numbers in btape "test". Possibly adjust in Bacula.
905 - Fix list volumes to output volume retention in some other
906 units, perhaps via a directive.
907 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
908 with multiple priorities.
909 - If you use restore replace=never, the directory attributes for
910 non-existent directories will not be restored properly.
912 - see lzma401.zip in others directory for new compression
914 - Allow the user to select JobType for manual pruning/purging.
915 - bscan does not put first of two volumes back with all info in
917 - Implement the FreeBSD nodump flag in chflags.
918 - Figure out how to make named console messages go only to that
919 console and to the non-restricted console (new console class?).
920 - Make restricted console prompt for password if *ask* is set or
921 perhaps if password is undefined.
922 - Implement "from ISO-date/time every x hours/days/weeks/months" in
925 ==== from Marc Schoechlin
926 - the help-command should be more verbose
927 (it should explain the paramters of the different
929 -> its time-comsuming to consult the manual anytime
930 you need a special parameter
931 -> maybe its more easy to maintain this, if the
932 descriptions of that commands are outsourced to
934 - the cd-command should allow complete paths
935 i.e. cd /foo/bar/foo/bar
936 -> if a customer mails me the path to a certain file,
937 its faster to enter the specified directory
938 - if the password is not configured in bconsole.conf
939 you should be asked for it.
940 -> sometimes you like to do restore on a customer-machine
941 which shouldnt know the password for bacula.
942 -> adding the password to the file favours admins
943 to forget to remove the password after usage
945 the protection of that file is less important
946 - long-listed-output of commands should be scrollable
947 like the unix more/less-command does
948 -> if someone runs 200 and more machines, the lists could
949 be a little long and complex
950 - command-output should be shown column by column
951 to reduce scrolling and to increase clarity
953 - lsmark should list the selected files with full
955 - wildcards for selecting and file and directories would be nice
956 - any actions should be interuptable with STRG+C
957 - command-expansion would be pretty cool
959 - When the replace Never option is set, new directory permissions
960 are not restored. See bug 213. To fix this requires creating a
961 list of newly restored directories so that those directory
962 permissions *can* be restored.
963 - Add prune all command
964 - Document fact that purge can destroy a part of a restore by purging
965 one volume while others remain valid -- perhaps mark Jobs.
966 - Add multiple-media-types.txt
967 - look at mxt-changer.html
968 - Make ? do a help command (no return needed).
969 - Implement restore directory.
970 - Document streams and how to implement them.
971 - Try not to re-backup a file if a new hard link is added.
972 - Add feature to backup hard links only, but not the data.
973 - Fix stream handling to be simpler.
974 - Add Priority and Bootstrap to Run a Job.
975 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
977 - Remove View FileSet button from Run a Job dialog.
978 - Handle prompt for restore job at end of Restore command.
979 - Add display of total selected files to Restore window.
980 - Add tree pane to left of window.
981 - Add progress meter.
982 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
983 - Add message to user to check for fixed block size when the forward
984 space test fails in btape.
985 - When unmarking a directory check if all files below are unmarked and
986 then remove the + flag -- in the restore tree.
987 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
988 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
989 - Revisit the question of multiple Volumes (disk) on a single device.
990 - Add a block copy option to bcopy.
991 - Finish work on Gnome restore GUI.
992 - Fix "llist jobid=xx" where no fileset or client exists.
993 - For each job type (Admin, Restore, ...) require only the really necessary
994 fields.- Pass Director resource name as an option to the Console.
995 - Add a "batch" mode to the Console (no unsolicited queries, ...).
996 - Add a .list all files in the restore tree (probably also a list all files)
997 Do both a long and short form.
998 - Allow browsing the catalog to see all versions of a file (with
999 stat data on each file).
1000 - Restore attributes of directory if replace=never set but directory
1002 - Use SHA1 on authentication if possible.
1003 - See comtest-xxx.zip for Windows code to talk to USB.
1004 - Add John's appended files:
1005 Appended = { /files/server/logs/http/*log }
1006 and such files would be treated as follows.On a FULL backup, they would
1007 be backed up like any other file.On an INCREMENTAL backup, where a
1008 previous INCREMENTAL or FULL was already in thecatalogue and the length
1009 of the file wasgreater than the length of the last backup, only thedata
1010 added since the last backup will be dumped.On an INCREMENTAL backup, if
1011 the length of the file is less than thelength of the file with the same
1012 name last backed up, the completefile is dumped.On Windows systems, with
1013 creation date of files, we can be evensmarter about this and not count
1014 entirely upon the length.On a restore, the full and all incrementals
1015 since it will beapplied in sequence to restore the file.
1016 - Check new HAVE_WIN32 open bits.
1017 - Check if the tape has moved before writing.
1018 - Handling removable disks -- see below:
1019 - Keep track of tape use time, and report when cleaning is necessary.
1020 - Add FromClient and ToClient keywords on restore command (or
1021 BackupClient RestoreClient).
1022 - Implement a JobSet, which groups any number of jobs. If the
1023 JobSet is started, all the jobs are started together.
1024 Allow Pool, Level, and Schedule overrides.
1025 - Enhance cancel to timeout BSOCK packets after a specific delay.
1026 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1027 ua_status.!!! Thanks to Alan Brown for this tip.
1028 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1029 correctly for multiple simultaneous jobs.
1030 - Correct code so that FileSet MD5 is calculated for < and | filename
1032 - Implement the Media record flag that indicates that the Volume does disk
1034 - Implement VolAddr, which is used when Volume is addressed like a disk,
1035 and form it from VolFile and VolBlock.
1036 - Make multiple restore jobs for multiple media types specifying
1037 the proper storage type.
1038 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1039 pointer (rec) to try_repositioning().
1040 - Look at extracting Win data from BackupRead.
1041 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1042 which would take precidence over the Catalog "JobRetention".
1043 - Implement Label Format in Add and Label console commands.
1044 - Possibly up network buffers to 65K. Put on variable.
1045 - Put email tape request delays on one or more variables. User wants
1046 to cancel the job after a certain time interval. Maximum Mount Wait?
1047 - Job, Client, Device, Pool, or Volume?
1048 Is it possible to make this a directive which is *optional* in multiple
1049 resources, like Level? If so, I think I'd make it an optional directive
1050 in Job, Client, and Pool, with precedence such that Job overrides Client
1051 which in turn overrides Pool.
1053 - New Storage specifications:
1054 - Want to write to multiple storage devices simultaneously
1055 - Want to write to multiple storage devices sequentially (in one job)
1056 - Want to read/write simultaneously
1057 - Key is MediaType -- it must match
1059 Passed to SD as a sort of BSR record called Storage Specification
1063 MediaType -> Next MediaType
1065 Device -> Next Device
1067 Allow multiple Storage specifications
1075 Allow Multiple Pool specifications (note, Pool currently
1077 Allow Multiple MediaType specifications in Dir conf
1078 Allow Multiple Device specifications in Dir conf
1079 Perhaps keep this in a single SSR
1080 Tie a Volume to a specific device by using a MediaType that
1081 is contained in only one device.
1082 In SD allow Device to have Multiple MediaTypes
1084 - Ideas from Jerry Scharf:
1085 First let's point out some big pluses that bacula has for this
1087 more importantly it's active. Thank you so much for that
1088 even more important, it's not flaky
1089 it has an open access catalog, opening many possibilities
1090 it's pushing toward heterogeneous systems capability
1092 Macintosh file client
1093 macs are an interesting niche, but I fear a server is a rathole
1094 working bare iron recovery for windows
1095 the option for inc/diff backups not reset on fileset revision
1096 a) use both change and inode update time against base time
1097 b) do the full catalog check (expensive but accurate)
1098 sizing guide (how much system is needed to back up N systems/files)
1099 consultants on using bacula in building a disaster recovery system
1100 an integration guide
1101 or how to get at fancy things that one could do with bacula
1102 logwatch code for bacula logs (or similar)
1103 linux distro inclusion of bacula (brings good and bad, but necessary)
1104 win2k/XP server capability (icky but you asked)
1105 support for Oracle database ??
1107 - Look at adding SQL server and Exchange support for Windows.
1108 - Make dev->file and dev->block_num signed integers so that -1 can
1109 be an invalid value which happens with BSR.
1110 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1111 is needed to properly specify ranges.
1112 - Add progress of files/bytes to SD and FD.
1113 - Print warning message if FileId > 4 billion
1114 - do a "messages" before the first prompt in Console
1115 - Client does not show busy during Estimate command.
1116 - Implement Console mtx commands.
1117 - Implement a Mount Command and an Unmount Command where
1118 the users could specify a system command to be performed
1119 to do the mount, after which Bacula could attempt to
1120 read the device. This is for Removeable media such as a CDROM.
1121 - Most likely, this mount command would be invoked explicitly
1122 by the user using the current Console "mount" and "unmount"
1123 commands -- the Storage Daemon would do the right thing
1124 depending on the exact nature of the device.
1125 - As with tape drives, when Bacula wanted a new removable
1126 disk mounted, it would unmount the old one, and send a message
1127 to the user, who would then use "mount" as described above
1128 once he had actually inserted the disk.
1129 - Implement dump/print label to UA
1130 - Spool to disk only when the tape is full, then when a tape is hung move
1132 - bextract is sending everything to the log file ****FIXME****
1133 - Allow multiple Storage specifications (or multiple names on
1134 a single Storage specification) in the Job record. Thus a job
1135 can be backed up to a number of storage devices.
1136 - Implement some way for the File daemon to contact the Director
1137 to start a job or pass its DHCP obtained IP number.
1138 - Implement a query tape prompt/replace feature for a console
1139 - Copy console @ code to gnome2-console
1140 - Make tree walk routines like cd, ls, ... more user friendly
1141 by handling spaces better.
1142 - Make sure that Bacula rechecks the tape after the 20 min wait.
1143 - Set IO_NOWAIT on Bacula TCP/IP packets.
1144 - Try doing a raw partition backup and restore by mounting a
1146 - From Lars Kellers:
1147 Yes, it would allow to highly automatic the request for new tapes. If a
1148 tape is empty, bacula reads the barcodes (native or simulated), and if
1149 an unused tape is found, it runs the label command with all the
1150 necessary parameters.
1152 By the way can bacula automatically "move" an empty/purged volume say
1153 in the "short" pool to the "long" pool if this pool runs out of volume
1155 - What to do about "list files job=xxx".
1156 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1157 file descriptor leak in Bacula.
1158 - Implement WrapCounters in Counters.
1159 - Add heartbeat from FD to SD if hb interval expires.
1160 - Can we dynamically change FileSets?
1161 - If pool specified to label command and Label Format is specified,
1162 automatically generate the Volume name.
1163 - Why can't SQL do the filename sort for restore?
1164 - Add ExhautiveRestoreSearch
1165 - Look at the possibility of loading only the necessary
1166 data into the restore tree (i.e. do it one directory at a
1167 time as the user walks through the tree).
1168 - Possibly use the hash code if the user selects all for a restore command.
1169 - Fix "restore all" to bypass building the tree.
1170 - Prohibit backing up archive device (findlib/find_one.c:128)
1171 - Implement Release Device in the Job resource to unmount a drive.
1172 - Implement Acquire Device in the Job resource to mount a drive,
1173 be sure this works with admin jobs so that the user can get
1174 prompted to insert the correct tape. Possibly some way to say to
1175 run the job but don't save the files.
1176 - Make things like list where a file is saved case independent for
1178 - Use autochanger to handle multiple devices.
1179 - Implement a Recycle command
1180 - Start working on Base jobs.
1181 - Implement UnsavedFiles DB record.
1182 - From Phil Stracchino:
1183 It would probably be a per-client option, and would be called
1184 something like, say, "Automatically purge obsoleted jobs". What it
1185 would do is, when you successfully complete a Differential backup of a
1186 client, it would automatically purge all Incremental backups for that
1187 client that are rendered redundant by that Differential. Likewise,
1188 when a Full backup on a client completed, it would automatically purge
1189 all Differential and Incremental jobs obsoleted by that Full backup.
1190 This would let people minimize the number of tapes they're keeping on
1191 hand without having to master the art of retention times.
1192 - When doing a Backup send all attributes back to the Director, who
1193 would then figure out what files have been deleted.
1194 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1195 explicit permission to do so. It should also mark the tape in error
1196 if there is an error.
1197 - Cancel waiting for Client connect in SD if FD goes away.
1199 - Implement timeout in response() when it should come quickly.
1200 - Implement a Slot priority (loaded/not loaded).
1201 - Implement "vacation" Incremental only saves.
1202 - Implement create "FileSet"?
1203 - Add prefixlinks to where or not where absolute links to FD.
1204 - Issue message to mount a new tape before the rewind.
1205 - Simplified client job initiation for portables.
1206 - If SD cannot open a drive, make it periodically retry.
1207 - Add more of the config info to the tape label.
1209 - Refine SD waiting output:
1210 Device is being positioned
1211 > Device is being positioned for append
1212 > Device is being positioned to file x
1214 - Figure out some way to estimate output size and to avoid splitting
1215 a backup across two Volumes -- this could be useful for writing CDROMs
1216 where you really prefer not to have it split -- not serious.
1217 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1218 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1219 actual data on the Volume and compare it.
1220 - Implement Bacula plugins -- design API
1221 - Make bcopy read through bad tape records.
1222 - Program files (i.e. execute a program to read/write files).
1223 Pass read date of last backup, size of file last time.
1224 - Add Signature type to File DB record.
1225 - CD into subdirectory when open()ing files for backup to
1226 speed up things. Test with testfind().
1227 - Priority job to go to top of list.
1228 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1229 - Implement some way for the Console to dynamically create a job.
1230 - Solaris -I on tar for include list
1231 - Need a verbose mode in restore, perhaps to bsr.
1232 - bscan without -v is too quiet -- perhaps show jobs.
1233 - Add code to reject whole blocks if not wanted on restore.
1234 - Check if we can increase Bacula FD priorty in Win2000
1235 - Make sure the MaxVolFiles is fully implemented in SD
1236 - Check if both CatalogFiles and UseCatalog are set to SD.
1237 - Possibly add email to Watchdog if drive is unmounted too
1238 long and a job is waiting on the drive.
1239 - After unmount, if restore job started, ask to mount.
1240 - Add UA rc and history files.
1241 - put termcap (used by console) in ./configure and
1242 allow -with-termcap-dir.
1243 - Fix Autoprune for Volumes to respect need for full save.
1244 - Compare tape to Client files (attributes, or attributes and data)
1245 - Make all database Ids 64 bit.
1246 - Allow console commands to detach or run in background.
1247 - Add SD message variables to control operator wait time
1248 - Maximum Operator Wait
1249 - Minimum Message Interval
1250 - Maximum Message Interval
1251 - Send Operator message when cannot read tape label.
1252 - Verify level=Volume (scan only), level=Data (compare of data to file).
1253 Verify level=Catalog, level=InitCatalog
1255 - Add keyword search to show command in Console.
1256 - Events : tape has more than xxx bytes.
1257 - Complete code in Bacula Resources -- this will permit
1258 reading a new config file at any time.
1259 - Handle ctl-c in Console
1260 - Implement script driven addition of File daemon to config files.
1261 - Think about how to make Bacula work better with File (non-tape) archives.
1262 - Write Unix emulator for Windows.
1263 - Put memory utilization in Status output of each daemon
1264 if full status requested or if some level of debug on.
1265 - Make database type selectable by .conf files i.e. at runtime
1266 - Set flag for uname -a. Add to Volume label.
1267 - Restore files modified after date
1268 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1269 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1270 - Timout a job or terminate if link goes down, or reopen link and query.
1271 - Concept of precious tapes (cannot be reused).
1272 - Make bcopy copy with a single tape drive.
1273 - Permit changing ownership during restore.

1287 - Autolabel should be specified by DIR instead of SD.
1289 - Add media capacity
1290 - AutoScan (check checksum of tape)
1291 - Format command = "format /dev/nst0"
1295 - Seek resolution (usually corresponds to buffer size)
1296 - EODErrorCode=ENOSPC or code
1297 - Partial Read error code
1298 - Partial write error code
1299 - Nonformatted read error
1300 - Nonformatted write error
1301 - WriteProtected error
1305 - IgnoreCloseErrors=yes
1315 - FD sends unsaved file list to Director at end of job (see
1317 - File daemon should build list of files skipped, and then
1318 at end of save retry and report any errors.
1319 - Write a Storage daemon that uses pipes and
1320 standard Unix programs to write to the tape.
1322 - Need something that monitors the JCR queue and
1323 times out jobs by asking the deamons where they are.
1324 - Enhance Jmsg code to permit buffering and saving to disk.
1325 - device driver = "xxxx" for drives.
1326 - Verify from Volume
1327 - Ensure that /dev/null works
1328 - Need report class for messages. Perhaps
1329 report resource where report=group of messages
1330 - enhance scan_attrib and rename scan_jobtype, and
1331 fill in code for "since" option
1332 - Director needs a time after which the report status is sent
1333 anyway -- or better yet, a retry time for the job.
1334 - Don't reschedule a job if previous incarnation is still running.
1335 - Some way to automatically backup everything is needed????
1336 - Need a structure for pending actions:
1338 - termination status (part of buffered msgs?)
1340 Read, Write, Clean, Delete
1341 - Login to Bacula; Bacula users with different permissions:
1342 owner, group, user, quotas
1343 - Store info on each file system type (probably in the job header on tape.
1344 This could be the output of df; or perhaps some sort of /etc/mtab record.
1346 ========= ideas ===============
1347 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1348 To: <kern@sibbald.com>
1349 Subject: RE: [Bacula-users] future large programming jobs
1350 Date: Thu, 26 Feb 2004 11:34:54 -0600
1352 I noticed the subject thread and thought I would offer the following
1353 merely as sources of ideas, i.e. something to think about, not even as
1354 strong as a request. In my former life (before retiring) I often
1355 dealt with backups and storage management issues/products as a
1356 developer and as a consultant. I am currently migrating my personal
1357 network from amanda to bacula specifically because of the ability to
1358 cross media boundaries during storing backups.
1359 Are you familiar with the commercial product called ADSM (I think IBM
1360 now sells it under the Tivoli label)? It has a couple of interesting
1361 ideas that may apply to the following topics.
1363 1. Migration: Consider that when you need to restore a system, there
1364 may be pressure to hurry. If all the information for a single client
1365 can eventually end up on the same media (and in chronological order),
1366 the restore is facillitated by not having to search past information
1367 from other clients. ADSM has the concept of "client affinity" that
1368 may be associated with it's storage pools. It seems to me that this
1369 concept (as an optional feature) might fit in your architecture for
1372 ADSM also has the concept of defining one or more storage pools as
1373 "copy pools" (almost mirrors, but only in the sense of contents).
1374 These pools provide the ability to have duplicte data stored both
1375 onsite and offsite. The copy process can be scheduled to be handled
1376 by their storage manager during periods when there is no backup
1377 activity. Again, the migration process might be a place to consider
1378 implementing something like this.
1381 > It strikes me that it would be very nice to be able to do things
1383 > have the Job(s) backing up the machines run, and once they have all
1384 > completed, start a migration job to copy the data from disks Volumes

1389 > mechanism described below would probably make it very easy.
1391 This is the goal. In the first step (before events), you simply
1393 the Migration to tape later.
1395 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1396 the database. Once a file (unique by path and metadata such as dates,
1397 size, ownership, etc.) is in a copy pool, no more copies are made. In
1398 other words, when you start ADSM, it begins like your concept of a
1399 base job. After that it is in the "incremental" mode. You can
1400 configure the number of "generations" of files to be retained, plus a
1401 retention date after which even old generations are purged. The
1402 database tracks the contents of media and projects the percentage of
1403 each volume that is valid. When the valid content of a volume drops
1404 below a configured percentage, the valid data are migrated to another
1405 volume and the old volume is marked as empty. Note, this requires
1406 ADSM to have an idea of the contents of a client, i.e. marking the
1407 database when an existing file was deleted, but this would solve your
1408 issue of restoring a client without restoring deleted files.
1410 This is pretty far from what bacula now does, but if you are going to
1411 rip things up for Base jobs,.....
1412 Also, the benefits of this are huge for very large shops, especially
1413 with media robots, but are a pain for shops with manual media
1417 > Base jobs sound pretty useful, but I'm not dying for them.
1419 Nobody is dying for them, but when you see what it does, you will die
1422 3. Restoring deleted files: Since I think my comments in (2) above
1423 have low probability of implementation, I'll also suggest that you
1424 could approach the issue of deleted files by a mechanism of having the
1425 fd report to the dir, a list of all files on the client for every
1426 backup job. The dir could note in the database entry for each file
1427 the date that the file was seen. Then if a restore as of date X takes
1428 place, only files that exist from before X until after X would be
1429 restored. Probably the major cost here is the extra date container in
1430 each row of the files table.
1432 Thanks for "listening". I hope some of this helps. If you want to
1433 contact me, please send me an email - I read some but not all of the
1434 mailing list traffic and might miss a reply there.
1436 Please accept my compliments for bacula. It is doing a great job for
1437 me!! I sympathize with you in the need to wrestle with excelence in
1438 execution vs. excelence in feature inclusion.
1443 ==============================
1446 - Design at hierarchial storage for Bacula. Migration and Clone.
1447 - Implement FSM (File System Modules).
1448 - Audit M_ error codes to ensure they are correct and consistent.
1449 - Add variable break characters to lex analyzer.
1450 Either a bit mask or a string of chars so that
1451 the caller can change the break characters.
1452 - Make a single T_BREAK to replace T_COMMA, etc.
1453 - Ensure that File daemon and Storage daemon can
1454 continue a save if the Director goes down (this
1455 is NOT currently the case). Must detect socket error,
1456 buffer messages for later.
1457 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1458 - Add ability to backup to two Storage devices (two SD sessions) at
1459 the same time -- e.g. onsite, offsite.
1460 - Add the ability to consolidate old backup sets (basically do a restore
1461 to tape and appropriately update the catalog). Compress Volume sets.
1462 Might need to spool via file is only one drive is available.
1463 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1464 someway to do so with every volume that has less than x% valid
1468 Migration: Move a backup from one Volume to another
1469 Clone: Copy a backup -- two Volumes
1472 ======================================================
1474 It is somewhat like a Full save becomes an incremental since
1475 the Base job (or jobs) plus other non-base files.
1477 - A Base backup is same as Full backup, just different type.
1478 - New BaseFiles table that contains:
1480 BaseJobId - Base JobId referenced for this FileId (needed ???)
1481 JobId - JobId currently running
1482 FileId - File not backed up, exists in Base Job
1483 FileIndex - FileIndex from Base Job.
1484 i.e. for each base file that exists but is not saved because
1485 it has not changed, the File daemon sends the JobId, BaseId,
1486 FileId, FileIndex back to the Director who creates the DB entry.
1487 - To initiate a Base save, the Director sends the FD
1488 the FileId, and full filename for each file in the Base.
1489 - When the FD finds a Base file, he requests the Director to
1490 send him the full File entry (stat packet plus MD5), or
1491 conversely, the FD sends it to the Director and the Director
1492 says yes or no. This can be quite rapid if the FileId is kept
1493 by the FD for each Base Filename.
1494 - It is probably better to have the comparison done by the FD
1495 despite the fact that the File entry must be sent across the
1497 - An alternative would be to send the FD the whole File entry
1498 from the start. The disadvantage is that it requires a lot of
1499 space. The advantage is that it requires less communications
1501 - The Job record must be updated to indicate that one or more
1503 - At end of Job, FD returns:
1504 1. Count of base files/bytes not written to tape (i.e. matches)
1505 2. Count of base file that were saved i.e. had changed.
1506 - No tape record would be written for a Base file that matches, in the
1507 same way that no tape record is written for Incremental jobs where
1508 the file is not saved because it is unchanged.
1509 - On a restore, all the Base file records must explicitly be
1510 found from the BaseFile tape. I.e. for each Full save that is marked
1511 to have one or more Base Jobs, search the BaseFile for all occurrences
1513 - An optimization might be to make the BaseFile have:
1519 This would avoid the need to explicitly fetch each File record for
1520 the Base job. The Base Job record will be fetched to get the
1521 VolSessionId and VolSessionTime.
1522 =========================================================
1525 ==========================================================
1527 For each Incremental job that is run, there may be files that
1528 were found but not saved because they were locked (this applies
1529 only to Windows). Such a system could send back to the Director
1530 a list of Unsaved files.
1532 - New UnSavedFiles table that contains:
1536 - Then in the next Incremental job, the list of Unsaved Files will be
1537 feed to the FD, who will ensure that they are explicitly chosen even
1538 if standard date/time check would not have selected them.
1539 =============================================================

1580 (just to verify it remembers where it came from, however it can be

1583 There needs to be a table of drive # to devices somewhere - If there are
1584 multiple changers or drives there may not be a 1:1 correspondance between
1585 changer drive number and system device name - and depending on the way the
1586 drives are hooked up to scsi busses, they may not be linearly numbered
1587 from an offset point either.something like
1589 Autochanger drives = 2
1590 Autochanger drive 0 = /dev/nst1
1591 Autochanger drive 1 = /dev/nst2
1592 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1593 times, not just for multidrive changers. For a 1 drive changer, that's
1599 MTX's manpage (1.2.15):
1600 unload [<slotnum>] [ <drivenum> ]
1601 Unloads media from drive <drivenum> into slot
1602 <slotnum>. If <drivenum> is omitted, defaults to
1603 drive 0 (as do all commands). If <slotnum> is
1604 omitted, defaults to the slot that the drive was
1605 loaded from. Note that there's currently no way
1606 to say 'unload drive 1's media to the slot it
1607 came from', other than to explicitly use that
1608 slot number as the destination.AB

1646 Handling removable disks
1648 From: Karl Cunningham <karlc@keckec.com>
1650 My backups are only to hard disk these days, in removable bays. This is my
1651 idea of how a backup to hard disk would work more smoothly. Some of these
1652 things Bacula does already, but I mention them for completeness. If others
1653 have better ways to do this, I'd like to hear about it.
1655 1. Accommodate several disks, rotated similar to how tapes are. Identified
1656 by partition volume ID or perhaps by the name of a subdirectory.
1657 2. Abort & notify the admin if the wrong disk is in the bay.
1658 3. Write backups to different subdirectories for each machine to be backed
1660 4. Volumes (files) get created as needed in the proper subdirectory, one
1662 5. When a disk is recycled, remove or zero all old backup files. This is
1663 important as the disk being recycled may be close to full. This may be
1664 better done manually since the backup files for many machines may be
1665 scattered in many subdirectories.
1670 - Make sure that all do_prompt() calls in Dir check for
1671 -1 (error) and -2 (cancel) returns.
1672 - Fix foreach_jcr() to have free_jcr() inside next().
1673 jcr=jcr_walk_start();
1674 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1677 - A Volume taken from Scratch should take on the retention period
1679 - Correct doc for Maximum Changer Wait (and others) accepting only
1681 - Implement status that shows why a job is being held in reserve, or
1682 rather why none of the drives are suitable.
1683 - Implement a way to disable a drive (so you can use the second
1684 drive of an autochanger, and the first one will not be used or
1686 - Make sure Maximum Volumes is respected in Pools when adding
1687 Volumes (e.g. when pulling a Scratch volume).
1688 - Keep same dcr when switching device ...
1689 - Implement code that makes the Dir aware that a drive is an
1690 autochanger (so the user doesn't need to use the Autochanger = yes
1692 - Make catalog respect ACL.
1693 - Add recycle count to Media record.
1694 - Add initial write date to Media record.
1695 - Fix store_yesno to be store_bitmask.
