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

157 better machine-readable output like "Ok" or "Error busy"
158 .move eject device=xxx toslot=yyy the same as above, but with a new

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

245 order by Path.Path ASC;
247 - Look into using Dart for testing
248 http://public.kitware.com/Dart/HTML/Index.shtml

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

427 - http://www.dwheeler.com/essays/commercial-floss.html
428 - Add VolumeLock to prevent all but lock holder (SD) from updating
429 the Volume data (with the exception of VolumeState).
430 - The btape fill command does not seem to use the Autochanger
431 - Make Windows installer default to system disk drive.
432 - Look at using ioctl(FIOBMAP, ...) on Linux, and
433 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
434 Win32 for sparse files.

437 - Directive: at <event> "command"
438 - Command: pycmd "command" generates "command" event. How to
439 attach to a specific job?
440 - Integrate Christopher's St. Bernard code.
441 - run_cmd() returns int should return JobId_t
442 - get_next_jobid_from_list() returns int should return JobId_t
443 - Document export LDFLAGS=-L/usr/lib64

445 - Network error on Win32 should set Win32 error code.
446 - What happens when you rename a Disk Volume?

449 - Look at -D_FORTIFY_SOURCE=2
450 - Add Win32 FileSet definition somewhere
451 - Look at fixing restore status stats in SD.
452 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
453 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
454 - Implement a mode that says when a hard read error is
455 encountered, read many times (as it currently does), and if the
456 block cannot be read, skip to the next block, and try again. If
457 that fails, skip to the next file and try again, ...
459 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
460 insert into LevelType (LevelType,LevelTypeLong) values
464 - Show files/second in client status output.
465 - Add a recursive mark command (rmark) to restore.
466 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
467 of the same level and does not permit multiple simultaneous
468 running of that Job (i.e. lets any previous invocation finish
469 before doing Interval testing).
470 - Look at simplifying File exclusions.
471 - New directive "Delete purged Volumes"
472 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
473 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
474 see if it become stable and I just have to supervise
476 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
477 PoolId, and when it is empty remove it.
478 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
480 - Allow Check Labels to be used with Bacula labels.
481 - "Resuming" a failed backup (lost line for example) by using the
482 failed backup as a sort of "base" job.
484 - Email to the user when the tape is about to need changing x
485 days before it needs changing.
486 - Command to show next tape that will be used for a job even
487 if the job is not scheduled.
488 - From: Arunav Mandal <amandal@trolltech.com>
489 1. When jobs are running and bacula for some reason crashes or if I do a
490 restart it remembers and jobs it was running before it crashed or restarted
491 as of now I loose all jobs if I restart it.
493 2. When spooling and in the midway if client is disconnected for instance a
494 laptop bacula completely discard the spool. It will be nice if it can write
495 that spool to tape so there will be some backups for that client if not all.
497 3. We have around 150 clients machines it will be nice to have a option to
498 upgrade all the client machines bacula version automatically.
500 4. Atleast one connection should be reserved for the bconsole so at heavy load
501 I should connect to the director via bconsole which at sometimes I can't
503 5. Another most important feature that is missing, say at 10am I manually
504 started backup of client abc and it was a full backup since client abc has
505 no backup history and at 10.30am bacula again automatically started backup of
506 client abc as that was in the schedule. So now we have 2 multiple Full
507 backups of the same client and if we again try to start a full backup of
508 client backup abc bacula won't complain. That should be fixed.
510 - Fix bpipe.c so that it does not modify results pointer.
511 ***FIXME*** calling sequence should be changed.
512 - For Windows disaster recovery see http://unattended.sf.net/
513 - regardless of the retention period, Bacula will not prune the
514 last Full, Diff, or Inc File data until a month after the
515 retention period for the last Full backup that was done.
516 - update volume=xxx --- add status=Full
517 - Remove old spool files on startup.
518 - Exclude SD spool/working directory.
519 - Refuse to prune last valid Full backup. Same goes for Catalog.
521 - Make a callback when Rerun failed levels is called.
522 - Give Python program access to Scheduled jobs.
523 - Add setting Volume State via Python.
524 - Python script to save with Python, not save, save with Bacula.
525 - Python script to do backup.
527 - Change the Priority, Client, Storage, JobStatus (error)
528 at the start of a job.
529 - Why is SpoolDirectory = /home/bacula/spool; not reported
530 as an error when writing a DVD?
531 - Make bootstrap file handle multiple MediaTypes (SD)
532 - Remove all old Device resource code in Dir and code to pass it
533 back in SD -- better, rework it to pass back device statistics.
534 - Check locking of resources -- be sure to lock devices where previously
535 resources were locked.
536 - The last part is left in the spool dir.
539 - In restore don't compare byte count on a raw device -- directory
540 entry does not contain bytes.
544 MA = (last_MA * 3 + rate) / 4
545 rate = (bytes - last_bytes) / (runtime - last_runtime)
546 - Max Vols limit in Pool off by one?
547 - Implement Files/Bytes,... stats for restore job.
548 - Implement Total Bytes Written, ... for restore job.
549 - Despool attributes simultaneously with data in a separate
550 thread, rejoined at end of data spooling.
551 - 7. Implement new Console commands to allow offlining/reserving drives,
552 and possibly manipulating the autochanger (much asked for).
553 - Add start/end date editing in messages (%t %T, %e?) ...
554 - Add ClientDefs similar to JobDefs.
555 - Print more info when bextract -p accepts a bad block.
556 - Fix FD JobType to be set before RunBeforeJob in FD.
557 - Look at adding full Volume and Pool information to a Volume
558 label so that bscan can get *all* the info.
559 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
560 and there is only one volume in the pool, refuse to do it -- otherwise
561 he fills the Volume, then immediately starts reusing it.
562 - Implement copies and stripes.
563 - Add history file to console.
564 - Each file on tape creates a JobMedia record. Peter has 4 million
565 files spread over 10000 tape files and four tapes. A restore takes
566 16 hours to build the restore list.
567 - Add and option to check if the file size changed during backup.
568 - Make sure SD deletes spool files on error exit.
569 - Delete old spool files when SD starts.
570 - When labeling tapes, if you enter 000026, Bacula uses
571 the tape index rather than the Volume name 000026.
572 - Add offline tape command to Bacula console.
574 Enter MediaId or Volume name: 32
575 Enter new Volume name: DLT-20Dec04
576 Automatically selected Pool: Default
577 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

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

734 === From Carsten Menke <bootsy52@gmx.net>
736 Following is a list of what I think in the situations where I'm faced with,
737 could be a usefull enhancement to bacula, which I'm certain other users will
738 benefit from as well.
740 1. NextJob/NextJobs Directive within a Job Resource in the form of
741 NextJobs = job1,job2.
744 I currently solved the problem with running multiple jobs each after each
745 by setting the Max Wait Time for a job to 8 hours, and give
746 the jobs different Priorities. However, there scenarios where
747 1 Job is directly depending on another job, so if the former job fails,
748 the job after it needn't to be run
749 while maybe other jobs should run despite of that
752 A Backup Job and a Verify job, if the backup job fails there is no need to run
753 the verify job, as the backup job already failed. However, one may like
754 to backup the Catalog to disk despite of that the main backup job failed.
757 I see that this is related to the Event Handlers which are on the ToDo
758 list, also it is maybe a good idea to check for the return value and
759 execute different actions based on the return value
762 3. offline capability to bconsole
765 Currently I use a script which I execute within the last Job via the
766 RunAfterJob Directive, to release and eject the tape.
767 So I have to call bconsole "release=Storage-Name" and afterwards
768 mt -f /dev/nst0 eject to get the tape out.
770 If I have multiple Storage Devices, than these may not be /dev/nst0 and
771 I have to modify the script or call it with parameters etc.
772 This would actually not be needed, as everything is already defined
773 in bacula-sd.conf and if I can invoke bconsole with the
774 storage name via $1 in the script than I'm done and information is
777 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
781 For the reason mentioned in 3. to have the ability to call a
782 script with /scripts/foobar %s and in the script use $1
783 to pass the Storage Name to bconsole
785 5. Setting Volume State within a Job Resource
788 Instead of using "Maximum Volume Jobs" in the Pool Resource,
789 I would have the possibilty to define
790 in a Job Resource that after this certain job is run, the Volume State
791 should be set to "Volume State = Used", this give more flexibility (IMHO).
793 6. Localization of Bacula Messages
796 Unfortunatley many,many people I work with don't speak english very well.
797 So if at least the Reporting messages would be localized then they
798 would understand that they have to change the tape,etc. etc.
800 I volunteer to do the german translations, and if I can convince my wife also
801 french and Morre (western african language).
803 7. OK, this is evil, probably bound to security risks and maybe not possible
804 due to the design of bacula.
806 Implementation of Backtics ( `command` ) for shell comand execution to
807 the "Label Format" Directive.
811 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
812 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
813 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
814 the localized name for the day of the week appended to the
815 format string. Then I have the tape labeled automatically with weekday
816 name in the correct language.
818 - Yes, that is surely the case. I probably should turn those into Warning
819 errors. In addition, you just made me think that it might not be bad to
820 add an option to check the file size after backing up the file and
821 report if it changes. This would be done as an option because it would
824 Kern, good idea. If you do do that, mention in the output: file
825 shrunk, or file expanded, just to make it obvious to the user
826 (without having to the refer to file size), just how the file size
829 Would this option be for all file, or just one file? Or a fileset?
830 - Make output from status use html table tags for nicely
831 presenting in a browser.
832 - Can one write tapes faster with 8192 byte block sizes?
833 - Document security problems with the same password for everyone in
834 rpm and Win32 releases.
835 - Browse generations of files.
836 - I've seen an error when my catalog's File table fills up. I
837 then have to recreate the File table with a larger maximum row
838 size. Relevant information is at
839 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
840 "Installing and Configuring MySQL" chapter should talk a bit
841 about this potential problem, and recommend a solution.
842 - For Solaris must use POSIX awk.
843 - Want speed of writing to tape while despooling.
844 - Supported autochanger:
852 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
853 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
854 - Add regex from http://www.pcre.org to Bacula for Win32.
855 - Use only shell tools no make in CDROM package.
856 - Include within include does it work?
857 - Implement a Pool of type Cleaning?
858 - Implement VolReadTime and VolWriteTime in SD
859 - Modify Backing up Your Database to include a bootstrap file.
860 - Think about making certain database errors fatal.
861 - Look at correcting the time jump in the scheduler for daylight
862 savings time changes.
863 - Add a "real" timer to network connections.
864 - Promote to Full = Time period
865 - Check dates entered by user for correctness (month/day/... ranges)
866 - Compress restore Volume listing by date and first file.
867 - Look at patches/bacula_db.b2z postgresql that loops during restore.
869 - Perhaps add read/write programs and/or plugins to FileSets.
870 - How to handle backing up portables ...
871 - Add some sort of guaranteed Interval for upgrading jobs.
872 - Can we write the state file after every job terminates? On Win32
873 the system crashes and the state file is not updated.
876 Documentation to do: (any release a little bit at a time)
877 - Doc to do unmount before removing magazine.
878 - Alternative to static linking "ldd prog" save all binaries listed,
879 restore them and point LD_LIBRARY_PATH to them.
880 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
881 - Document query file format.
882 - Add more documentation for bsr files.
883 - Document problems with Verify and pruning.
884 - Document how to use multiple databases.
885 - VXA drives have a "cleaning required"
886 indicator, but Exabyte recommends preventive cleaning after every 75
889 In this context, it should be noted that Exabyte has a command-line
890 vxatool utility available for free download. (The current version is
891 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
892 test the drive, unload tapes, change drive settings, flash new firmware,
894 Of particular interest in this context is that vxatool <device> -i will
895 report, among other details, the time since last cleaning in tape motion
896 minutes. This information can be retrieved (and settings changed, for
897 that matter) through the generic-SCSI device even when Bacula has the
898 regular tape device locked. (Needless to say, I don't recommend
899 changing tape settings while a job is running.)
900 - Lookup HP cleaning recommendations.
901 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
902 - Document doing table repair
905 ===================================
906 - Add macro expansions in JobDefs.
907 Run Before Job = "SomeFile %{Level} %{Client}"
908 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
909 - Use non-blocking network I/O but if no data is available, use
911 - Use gather write() for network I/O.
912 - Autorestart on crash.
913 - Add bandwidth limiting.
914 - Add acks every once and a while from the SD to keep
915 the line from timing out.
916 - When an error in input occurs and conio beeps, you can back
917 up through the prompt.
918 - Detect fixed tape block mode during positioning by looking at
919 block numbers in btape "test". Possibly adjust in Bacula.
920 - Fix list volumes to output volume retention in some other
921 units, perhaps via a directive.
922 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
923 with multiple priorities.
924 - If you use restore replace=never, the directory attributes for
925 non-existent directories will not be restored properly.
927 - see lzma401.zip in others directory for new compression
929 - Allow the user to select JobType for manual pruning/purging.
930 - bscan does not put first of two volumes back with all info in
932 - Implement the FreeBSD nodump flag in chflags.
933 - Figure out how to make named console messages go only to that
934 console and to the non-restricted console (new console class?).
935 - Make restricted console prompt for password if *ask* is set or
936 perhaps if password is undefined.
937 - Implement "from ISO-date/time every x hours/days/weeks/months" in
940 ==== from Marc Schoechlin
941 - the help-command should be more verbose
942 (it should explain the paramters of the different
944 -> its time-comsuming to consult the manual anytime
945 you need a special parameter
946 -> maybe its more easy to maintain this, if the
947 descriptions of that commands are outsourced to
949 - the cd-command should allow complete paths
950 i.e. cd /foo/bar/foo/bar
951 -> if a customer mails me the path to a certain file,
952 its faster to enter the specified directory
953 - if the password is not configured in bconsole.conf
954 you should be asked for it.
955 -> sometimes you like to do restore on a customer-machine
956 which shouldnt know the password for bacula.
957 -> adding the password to the file favours admins
958 to forget to remove the password after usage
960 the protection of that file is less important
961 - long-listed-output of commands should be scrollable
962 like the unix more/less-command does
963 -> if someone runs 200 and more machines, the lists could
964 be a little long and complex
965 - command-output should be shown column by column
966 to reduce scrolling and to increase clarity
968 - lsmark should list the selected files with full
970 - wildcards for selecting and file and directories would be nice
971 - any actions should be interuptable with STRG+C
972 - command-expansion would be pretty cool
974 - When the replace Never option is set, new directory permissions
975 are not restored. See bug 213. To fix this requires creating a
976 list of newly restored directories so that those directory
977 permissions *can* be restored.
978 - Add prune all command
979 - Document fact that purge can destroy a part of a restore by purging
980 one volume while others remain valid -- perhaps mark Jobs.
981 - Add multiple-media-types.txt
982 - look at mxt-changer.html
983 - Make ? do a help command (no return needed).
984 - Implement restore directory.
985 - Document streams and how to implement them.
986 - Try not to re-backup a file if a new hard link is added.
987 - Add feature to backup hard links only, but not the data.
988 - Fix stream handling to be simpler.
989 - Add Priority and Bootstrap to Run a Job.
990 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
992 - Remove View FileSet button from Run a Job dialog.
993 - Handle prompt for restore job at end of Restore command.
994 - Add display of total selected files to Restore window.
995 - Add tree pane to left of window.
996 - Add progress meter.
997 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
998 - Add message to user to check for fixed block size when the forward
999 space test fails in btape.
1000 - When unmarking a directory check if all files below are unmarked and
1001 then remove the + flag -- in the restore tree.
1002 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1003 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1004 - Revisit the question of multiple Volumes (disk) on a single device.
1005 - Add a block copy option to bcopy.
1006 - Finish work on Gnome restore GUI.
1007 - Fix "llist jobid=xx" where no fileset or client exists.
1008 - For each job type (Admin, Restore, ...) require only the really necessary
1009 fields.- Pass Director resource name as an option to the Console.
1010 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1011 - Add a .list all files in the restore tree (probably also a list all files)
1012 Do both a long and short form.
1013 - Allow browsing the catalog to see all versions of a file (with
1014 stat data on each file).
1015 - Restore attributes of directory if replace=never set but directory
1017 - Use SHA1 on authentication if possible.
1018 - See comtest-xxx.zip for Windows code to talk to USB.
1019 - Add John's appended files:
1020 Appended = { /files/server/logs/http/*log }
1021 and such files would be treated as follows.On a FULL backup, they would
1022 be backed up like any other file.On an INCREMENTAL backup, where a
1023 previous INCREMENTAL or FULL was already in thecatalogue and the length
1024 of the file wasgreater than the length of the last backup, only thedata
1025 added since the last backup will be dumped.On an INCREMENTAL backup, if
1026 the length of the file is less than thelength of the file with the same
1027 name last backed up, the completefile is dumped.On Windows systems, with
1028 creation date of files, we can be evensmarter about this and not count
1029 entirely upon the length.On a restore, the full and all incrementals
1030 since it will beapplied in sequence to restore the file.
1031 - Check new HAVE_WIN32 open bits.
1032 - Check if the tape has moved before writing.
1033 - Handling removable disks -- see below:
1034 - Keep track of tape use time, and report when cleaning is necessary.
1035 - Add FromClient and ToClient keywords on restore command (or
1036 BackupClient RestoreClient).
1037 - Implement a JobSet, which groups any number of jobs. If the
1038 JobSet is started, all the jobs are started together.
1039 Allow Pool, Level, and Schedule overrides.
1040 - Enhance cancel to timeout BSOCK packets after a specific delay.
1041 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1042 ua_status.!!! Thanks to Alan Brown for this tip.
1043 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1044 correctly for multiple simultaneous jobs.
1045 - Correct code so that FileSet MD5 is calculated for < and | filename
1047 - Implement the Media record flag that indicates that the Volume does disk
1049 - Implement VolAddr, which is used when Volume is addressed like a disk,
1050 and form it from VolFile and VolBlock.
1051 - Make multiple restore jobs for multiple media types specifying
1052 the proper storage type.
1053 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1054 pointer (rec) to try_repositioning().
1055 - Look at extracting Win data from BackupRead.
1056 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1057 which would take precidence over the Catalog "JobRetention".
1058 - Implement Label Format in Add and Label console commands.
1059 - Possibly up network buffers to 65K. Put on variable.
1060 - Put email tape request delays on one or more variables. User wants
1061 to cancel the job after a certain time interval. Maximum Mount Wait?
1062 - Job, Client, Device, Pool, or Volume?
1063 Is it possible to make this a directive which is *optional* in multiple
1064 resources, like Level? If so, I think I'd make it an optional directive
1065 in Job, Client, and Pool, with precedence such that Job overrides Client
1066 which in turn overrides Pool.
1068 - New Storage specifications:
1069 - Want to write to multiple storage devices simultaneously
1070 - Want to write to multiple storage devices sequentially (in one job)
1071 - Want to read/write simultaneously
1072 - Key is MediaType -- it must match
1074 Passed to SD as a sort of BSR record called Storage Specification
1078 MediaType -> Next MediaType
1080 Device -> Next Device
1082 Allow multiple Storage specifications
1090 Allow Multiple Pool specifications (note, Pool currently
1092 Allow Multiple MediaType specifications in Dir conf
1093 Allow Multiple Device specifications in Dir conf
1094 Perhaps keep this in a single SSR
1095 Tie a Volume to a specific device by using a MediaType that
1096 is contained in only one device.
1097 In SD allow Device to have Multiple MediaTypes
1099 - Ideas from Jerry Scharf:
1100 First let's point out some big pluses that bacula has for this
1102 more importantly it's active. Thank you so much for that
1103 even more important, it's not flaky
1104 it has an open access catalog, opening many possibilities
1105 it's pushing toward heterogeneous systems capability
1107 Macintosh file client
1108 macs are an interesting niche, but I fear a server is a rathole
1109 working bare iron recovery for windows
1110 the option for inc/diff backups not reset on fileset revision
1111 a) use both change and inode update time against base time
1112 b) do the full catalog check (expensive but accurate)
1113 sizing guide (how much system is needed to back up N systems/files)
1114 consultants on using bacula in building a disaster recovery system
1115 an integration guide
1116 or how to get at fancy things that one could do with bacula
1117 logwatch code for bacula logs (or similar)
1118 linux distro inclusion of bacula (brings good and bad, but necessary)
1119 win2k/XP server capability (icky but you asked)
1120 support for Oracle database ??
1122 - Look at adding SQL server and Exchange support for Windows.
1123 - Make dev->file and dev->block_num signed integers so that -1 can
1124 be an invalid value which happens with BSR.
1125 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1126 is needed to properly specify ranges.
1127 - Add progress of files/bytes to SD and FD.
1128 - Print warning message if FileId > 4 billion
1129 - do a "messages" before the first prompt in Console
1130 - Client does not show busy during Estimate command.
1131 - Implement Console mtx commands.
1132 - Implement a Mount Command and an Unmount Command where
1133 the users could specify a system command to be performed
1134 to do the mount, after which Bacula could attempt to
1135 read the device. This is for Removeable media such as a CDROM.
1136 - Most likely, this mount command would be invoked explicitly
1137 by the user using the current Console "mount" and "unmount"
1138 commands -- the Storage Daemon would do the right thing
1139 depending on the exact nature of the device.
1140 - As with tape drives, when Bacula wanted a new removable
1141 disk mounted, it would unmount the old one, and send a message
1142 to the user, who would then use "mount" as described above
1143 once he had actually inserted the disk.
1144 - Implement dump/print label to UA
1145 - Spool to disk only when the tape is full, then when a tape is hung move
1147 - bextract is sending everything to the log file ****FIXME****
1148 - Allow multiple Storage specifications (or multiple names on
1149 a single Storage specification) in the Job record. Thus a job
1150 can be backed up to a number of storage devices.
1151 - Implement some way for the File daemon to contact the Director
1152 to start a job or pass its DHCP obtained IP number.
1153 - Implement a query tape prompt/replace feature for a console
1154 - Copy console @ code to gnome2-console
1155 - Make tree walk routines like cd, ls, ... more user friendly
1156 by handling spaces better.
1157 - Make sure that Bacula rechecks the tape after the 20 min wait.
1158 - Set IO_NOWAIT on Bacula TCP/IP packets.
1159 - Try doing a raw partition backup and restore by mounting a
1161 - From Lars Kellers:
1162 Yes, it would allow to highly automatic the request for new tapes. If a
1163 tape is empty, bacula reads the barcodes (native or simulated), and if
1164 an unused tape is found, it runs the label command with all the
1165 necessary parameters.
1167 By the way can bacula automatically "move" an empty/purged volume say
1168 in the "short" pool to the "long" pool if this pool runs out of volume
1170 - What to do about "list files job=xxx".
1171 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1172 file descriptor leak in Bacula.
1173 - Implement WrapCounters in Counters.
1174 - Add heartbeat from FD to SD if hb interval expires.
1175 - Can we dynamically change FileSets?
1176 - If pool specified to label command and Label Format is specified,
1177 automatically generate the Volume name.
1178 - Why can't SQL do the filename sort for restore?
1179 - Add ExhautiveRestoreSearch
1180 - Look at the possibility of loading only the necessary
1181 data into the restore tree (i.e. do it one directory at a
1182 time as the user walks through the tree).
1183 - Possibly use the hash code if the user selects all for a restore command.
1184 - Fix "restore all" to bypass building the tree.
1185 - Prohibit backing up archive device (findlib/find_one.c:128)
1186 - Implement Release Device in the Job resource to unmount a drive.
1187 - Implement Acquire Device in the Job resource to mount a drive,
1188 be sure this works with admin jobs so that the user can get
1189 prompted to insert the correct tape. Possibly some way to say to
1190 run the job but don't save the files.
1191 - Make things like list where a file is saved case independent for
1193 - Use autochanger to handle multiple devices.
1194 - Implement a Recycle command
1195 - Start working on Base jobs.
1196 - Implement UnsavedFiles DB record.
1197 - From Phil Stracchino:
1198 It would probably be a per-client option, and would be called
1199 something like, say, "Automatically purge obsoleted jobs". What it
1200 would do is, when you successfully complete a Differential backup of a
1201 client, it would automatically purge all Incremental backups for that
1202 client that are rendered redundant by that Differential. Likewise,
1203 when a Full backup on a client completed, it would automatically purge
1204 all Differential and Incremental jobs obsoleted by that Full backup.
1205 This would let people minimize the number of tapes they're keeping on
1206 hand without having to master the art of retention times.
1207 - When doing a Backup send all attributes back to the Director, who
1208 would then figure out what files have been deleted.
1209 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1210 explicit permission to do so. It should also mark the tape in error
1211 if there is an error.
1212 - Cancel waiting for Client connect in SD if FD goes away.
1214 - Implement timeout in response() when it should come quickly.
1215 - Implement a Slot priority (loaded/not loaded).
1216 - Implement "vacation" Incremental only saves.
1217 - Implement create "FileSet"?
1218 - Add prefixlinks to where or not where absolute links to FD.
1219 - Issue message to mount a new tape before the rewind.
1220 - Simplified client job initiation for portables.
1221 - If SD cannot open a drive, make it periodically retry.
1222 - Add more of the config info to the tape label.
1224 - Refine SD waiting output:
1225 Device is being positioned
1226 > Device is being positioned for append
1227 > Device is being positioned to file x
1229 - Figure out some way to estimate output size and to avoid splitting
1230 a backup across two Volumes -- this could be useful for writing CDROMs
1231 where you really prefer not to have it split -- not serious.
1232 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1233 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1234 actual data on the Volume and compare it.
1235 - Implement Bacula plugins -- design API
1236 - Make bcopy read through bad tape records.
1237 - Program files (i.e. execute a program to read/write files).
1238 Pass read date of last backup, size of file last time.
1239 - Add Signature type to File DB record.
1240 - CD into subdirectory when open()ing files for backup to
1241 speed up things. Test with testfind().
1242 - Priority job to go to top of list.
1243 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1244 - Implement some way for the Console to dynamically create a job.
1245 - Solaris -I on tar for include list
1246 - Need a verbose mode in restore, perhaps to bsr.
1247 - bscan without -v is too quiet -- perhaps show jobs.
1248 - Add code to reject whole blocks if not wanted on restore.
1249 - Check if we can increase Bacula FD priorty in Win2000
1250 - Make sure the MaxVolFiles is fully implemented in SD
1251 - Check if both CatalogFiles and UseCatalog are set to SD.
1252 - Possibly add email to Watchdog if drive is unmounted too
1253 long and a job is waiting on the drive.
1254 - After unmount, if restore job started, ask to mount.
1255 - Add UA rc and history files.
1256 - put termcap (used by console) in ./configure and
1257 allow -with-termcap-dir.
1258 - Fix Autoprune for Volumes to respect need for full save.
1259 - Compare tape to Client files (attributes, or attributes and data)
1260 - Make all database Ids 64 bit.
1261 - Allow console commands to detach or run in background.
1262 - Add SD message variables to control operator wait time
1263 - Maximum Operator Wait
1264 - Minimum Message Interval
1265 - Maximum Message Interval
1266 - Send Operator message when cannot read tape label.
1267 - Verify level=Volume (scan only), level=Data (compare of data to file).
1268 Verify level=Catalog, level=InitCatalog
1270 - Add keyword search to show command in Console.
1271 - Events : tape has more than xxx bytes.
1272 - Complete code in Bacula Resources -- this will permit
1273 reading a new config file at any time.
1274 - Handle ctl-c in Console
1275 - Implement script driven addition of File daemon to config files.
1276 - Think about how to make Bacula work better with File (non-tape) archives.
1277 - Write Unix emulator for Windows.
1278 - Put memory utilization in Status output of each daemon
1279 if full status requested or if some level of debug on.
1280 - Make database type selectable by .conf files i.e. at runtime
1281 - Set flag for uname -a. Add to Volume label.
1282 - Restore files modified after date
1283 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1284 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1285 - Timout a job or terminate if link goes down, or reopen link and query.
1286 - Concept of precious tapes (cannot be reused).
1287 - Make bcopy copy with a single tape drive.
1288 - Permit changing ownership during restore.

1302 - Autolabel should be specified by DIR instead of SD.
1304 - Add media capacity
1305 - AutoScan (check checksum of tape)
1306 - Format command = "format /dev/nst0"
1310 - Seek resolution (usually corresponds to buffer size)
1311 - EODErrorCode=ENOSPC or code
1312 - Partial Read error code

1330 - FD sends unsaved file list to Director at end of job (see
1332 - File daemon should build list of files skipped, and then
1333 at end of save retry and report any errors.
1334 - Write a Storage daemon that uses pipes and
1335 standard Unix programs to write to the tape.
1337 - Need something that monitors the JCR queue and
1338 times out jobs by asking the deamons where they are.
1339 - Enhance Jmsg code to permit buffering and saving to disk.
1340 - device driver = "xxxx" for drives.
1341 - Verify from Volume
1342 - Ensure that /dev/null works
1343 - Need report class for messages. Perhaps
1344 report resource where report=group of messages
1345 - enhance scan_attrib and rename scan_jobtype, and
1346 fill in code for "since" option
1347 - Director needs a time after which the report status is sent
1348 anyway -- or better yet, a retry time for the job.
1349 - Don't reschedule a job if previous incarnation is still running.
1350 - Some way to automatically backup everything is needed????
1351 - Need a structure for pending actions:
1353 - termination status (part of buffered msgs?)
1355 Read, Write, Clean, Delete
1356 - Login to Bacula; Bacula users with different permissions:
1357 owner, group, user, quotas
1358 - Store info on each file system type (probably in the job header on tape.
1359 This could be the output of df; or perhaps some sort of /etc/mtab record.
1361 ========= ideas ===============
1362 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1363 To: <kern@sibbald.com>
1364 Subject: RE: [Bacula-users] future large programming jobs
1365 Date: Thu, 26 Feb 2004 11:34:54 -0600
1367 I noticed the subject thread and thought I would offer the following
1368 merely as sources of ideas, i.e. something to think about, not even as
1369 strong as a request. In my former life (before retiring) I often
1370 dealt with backups and storage management issues/products as a
1371 developer and as a consultant. I am currently migrating my personal
1372 network from amanda to bacula specifically because of the ability to
1373 cross media boundaries during storing backups.
1374 Are you familiar with the commercial product called ADSM (I think IBM
1375 now sells it under the Tivoli label)? It has a couple of interesting
1376 ideas that may apply to the following topics.
1378 1. Migration: Consider that when you need to restore a system, there
1379 may be pressure to hurry. If all the information for a single client
1380 can eventually end up on the same media (and in chronological order),
1381 the restore is facillitated by not having to search past information
1382 from other clients. ADSM has the concept of "client affinity" that
1383 may be associated with it's storage pools. It seems to me that this
1384 concept (as an optional feature) might fit in your architecture for
1387 ADSM also has the concept of defining one or more storage pools as
1388 "copy pools" (almost mirrors, but only in the sense of contents).
1389 These pools provide the ability to have duplicte data stored both
1390 onsite and offsite. The copy process can be scheduled to be handled
1391 by their storage manager during periods when there is no backup
1392 activity. Again, the migration process might be a place to consider
1393 implementing something like this.
1396 > It strikes me that it would be very nice to be able to do things
1398 > have the Job(s) backing up the machines run, and once they have all

1404 > mechanism described below would probably make it very easy.
1406 This is the goal. In the first step (before events), you simply
1408 the Migration to tape later.
1410 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1411 the database. Once a file (unique by path and metadata such as dates,
1412 size, ownership, etc.) is in a copy pool, no more copies are made. In
1413 other words, when you start ADSM, it begins like your concept of a
1414 base job. After that it is in the "incremental" mode. You can
1415 configure the number of "generations" of files to be retained, plus a
1416 retention date after which even old generations are purged. The
1417 database tracks the contents of media and projects the percentage of
1418 each volume that is valid. When the valid content of a volume drops
1419 below a configured percentage, the valid data are migrated to another
1420 volume and the old volume is marked as empty. Note, this requires
1421 ADSM to have an idea of the contents of a client, i.e. marking the
1422 database when an existing file was deleted, but this would solve your
1423 issue of restoring a client without restoring deleted files.
1425 This is pretty far from what bacula now does, but if you are going to
1426 rip things up for Base jobs,.....
1427 Also, the benefits of this are huge for very large shops, especially
1428 with media robots, but are a pain for shops with manual media
1432 > Base jobs sound pretty useful, but I'm not dying for them.
1434 Nobody is dying for them, but when you see what it does, you will die
1437 3. Restoring deleted files: Since I think my comments in (2) above
1438 have low probability of implementation, I'll also suggest that you
1439 could approach the issue of deleted files by a mechanism of having the
1440 fd report to the dir, a list of all files on the client for every
1441 backup job. The dir could note in the database entry for each file
1442 the date that the file was seen. Then if a restore as of date X takes
1443 place, only files that exist from before X until after X would be
1444 restored. Probably the major cost here is the extra date container in
1445 each row of the files table.
1447 Thanks for "listening". I hope some of this helps. If you want to
1448 contact me, please send me an email - I read some but not all of the
1449 mailing list traffic and might miss a reply there.
1451 Please accept my compliments for bacula. It is doing a great job for
1452 me!! I sympathize with you in the need to wrestle with excelence in
1453 execution vs. excelence in feature inclusion.
1458 ==============================
1461 - Design at hierarchial storage for Bacula. Migration and Clone.
1462 - Implement FSM (File System Modules).
1463 - Audit M_ error codes to ensure they are correct and consistent.
1464 - Add variable break characters to lex analyzer.
1465 Either a bit mask or a string of chars so that
1466 the caller can change the break characters.
1467 - Make a single T_BREAK to replace T_COMMA, etc.
1468 - Ensure that File daemon and Storage daemon can
1469 continue a save if the Director goes down (this
1470 is NOT currently the case). Must detect socket error,
1471 buffer messages for later.
1472 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1473 - Add ability to backup to two Storage devices (two SD sessions) at
1474 the same time -- e.g. onsite, offsite.
1475 - Add the ability to consolidate old backup sets (basically do a restore
1476 to tape and appropriately update the catalog). Compress Volume sets.
1477 Might need to spool via file is only one drive is available.
1478 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1479 someway to do so with every volume that has less than x% valid
1483 Migration: Move a backup from one Volume to another
1484 Clone: Copy a backup -- two Volumes
1487 ======================================================
1489 It is somewhat like a Full save becomes an incremental since
1490 the Base job (or jobs) plus other non-base files.
1492 - A Base backup is same as Full backup, just different type.
1493 - New BaseFiles table that contains:
1495 BaseJobId - Base JobId referenced for this FileId (needed ???)
1496 JobId - JobId currently running
1497 FileId - File not backed up, exists in Base Job
1498 FileIndex - FileIndex from Base Job.
1499 i.e. for each base file that exists but is not saved because
1500 it has not changed, the File daemon sends the JobId, BaseId,
1501 FileId, FileIndex back to the Director who creates the DB entry.
1502 - To initiate a Base save, the Director sends the FD
1503 the FileId, and full filename for each file in the Base.
1504 - When the FD finds a Base file, he requests the Director to
1505 send him the full File entry (stat packet plus MD5), or
1506 conversely, the FD sends it to the Director and the Director
1507 says yes or no. This can be quite rapid if the FileId is kept
1508 by the FD for each Base Filename.
1509 - It is probably better to have the comparison done by the FD
1510 despite the fact that the File entry must be sent across the
1512 - An alternative would be to send the FD the whole File entry
1513 from the start. The disadvantage is that it requires a lot of
1514 space. The advantage is that it requires less communications
1516 - The Job record must be updated to indicate that one or more
1518 - At end of Job, FD returns:
1519 1. Count of base files/bytes not written to tape (i.e. matches)
1520 2. Count of base file that were saved i.e. had changed.
1521 - No tape record would be written for a Base file that matches, in the
1522 same way that no tape record is written for Incremental jobs where
1523 the file is not saved because it is unchanged.
1524 - On a restore, all the Base file records must explicitly be
1525 found from the BaseFile tape. I.e. for each Full save that is marked
1526 to have one or more Base Jobs, search the BaseFile for all occurrences
1528 - An optimization might be to make the BaseFile have:
1534 This would avoid the need to explicitly fetch each File record for
1535 the Base job. The Base Job record will be fetched to get the
1536 VolSessionId and VolSessionTime.
1537 =========================================================
1540 ==========================================================
1542 For each Incremental job that is run, there may be files that
1543 were found but not saved because they were locked (this applies
1544 only to Windows). Such a system could send back to the Director
1545 a list of Unsaved files.
1547 - New UnSavedFiles table that contains:
1551 - Then in the next Incremental job, the list of Unsaved Files will be
1552 feed to the FD, who will ensure that they are explicitly chosen even
1553 if standard date/time check would not have selected them.

1598 There needs to be a table of drive # to devices somewhere - If there are
1599 multiple changers or drives there may not be a 1:1 correspondance between
1600 changer drive number and system device name - and depending on the way the
1601 drives are hooked up to scsi busses, they may not be linearly numbered
1602 from an offset point either.something like
1604 Autochanger drives = 2
1605 Autochanger drive 0 = /dev/nst1
1606 Autochanger drive 1 = /dev/nst2
1607 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1608 times, not just for multidrive changers. For a 1 drive changer, that's
1614 MTX's manpage (1.2.15):
1615 unload [<slotnum>] [ <drivenum> ]
1616 Unloads media from drive <drivenum> into slot
1617 <slotnum>. If <drivenum> is omitted, defaults to
1618 drive 0 (as do all commands). If <slotnum> is
1619 omitted, defaults to the slot that the drive was
1620 loaded from. Note that there's currently no way
1621 to say 'unload drive 1's media to the slot it
1622 came from', other than to explicitly use that
1623 slot number as the destination.AB

1661 Handling removable disks
1663 From: Karl Cunningham <karlc@keckec.com>
1665 My backups are only to hard disk these days, in removable bays. This is my
1666 idea of how a backup to hard disk would work more smoothly. Some of these
1667 things Bacula does already, but I mention them for completeness. If others
1668 have better ways to do this, I'd like to hear about it.
1670 1. Accommodate several disks, rotated similar to how tapes are. Identified
1671 by partition volume ID or perhaps by the name of a subdirectory.
1672 2. Abort & notify the admin if the wrong disk is in the bay.
1673 3. Write backups to different subdirectories for each machine to be backed
1675 4. Volumes (files) get created as needed in the proper subdirectory, one
1677 5. When a disk is recycled, remove or zero all old backup files. This is
1678 important as the disk being recycled may be close to full. This may be
1679 better done manually since the backup files for many machines may be
1680 scattered in many subdirectories.
1685 - Make sure that all do_prompt() calls in Dir check for
1686 -1 (error) and -2 (cancel) returns.
1687 - Fix foreach_jcr() to have free_jcr() inside next().
1688 jcr=jcr_walk_start();
1689 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1692 - A Volume taken from Scratch should take on the retention period
1694 - Correct doc for Maximum Changer Wait (and others) accepting only
1696 - Implement status that shows why a job is being held in reserve, or
1697 rather why none of the drives are suitable.
1698 - Implement a way to disable a drive (so you can use the second
1699 drive of an autochanger, and the first one will not be used or
1701 - Make sure Maximum Volumes is respected in Pools when adding
1702 Volumes (e.g. when pulling a Scratch volume).
1703 - Keep same dcr when switching device ...
1704 - Implement code that makes the Dir aware that a drive is an
1705 autochanger (so the user doesn't need to use the Autochanger = yes
