117 - Modify SD status command to indicate when the SD is writing
118 to a DVD (the device is not open -- see bug #732).
119 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
120 and possibly changing the blobs into varchar.
121 - Ensure that the SD re-reads the Media record if the JobFiles

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

243 - Possibly allow SD to spool even if a tape is not mounted.
244 - It appears to me that you have run into some sort of race
245 condition where two threads want to use the same Volume and they
246 were both given access. Normally that is no problem. However,
247 one thread wanted the particular Volume in drive 0, but it was
248 loaded into drive 1 so it decided to unload it from drive 1 and
249 then loaded it into drive 0, while the second thread went on
250 thinking that the Volume could be used in drive 1 not realizing
251 that in between time, it was loaded in drive 0.
252 I'll look at the code to see if there is some way we can avoid
253 this kind of problem. Probably the best solution is to make the
254 first thread simply start using the Volume in drive 1 rather than
255 transferring it to drive 0.
256 - Fix re-read of last block to check if job has actually written
257 a block, and check if block was written by a different job
258 (i.e. multiple simultaneous jobs writing).
259 - Figure out how to configure query.sql. Suggestion to use m4:
260 == changequote.m4 ===
261 changequote(`[',`]')dnl
262 ==== query.sql.in ===
263 :List next 20 volumes to expire
265 Pool.Name AS PoolName,
270 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
272 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
276 ON Media.PoolId=Pool.PoolId
277 WHERE Media.LastWritten>0
281 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
283 The problem is that it requires m4, which is not present on all machines
285 - Given all the problems with FIFOs, I think the solution is to do something a
286 little different, though I will look at the code and see if there is not some
287 simple solution (i.e. some bug that was introduced). What might be a better
288 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
289 write data to a program rather than the FIFO. For example, suppose you
294 Then, I could imagine if you backup and restore this file with a direct
295 reference as is currently done for fifos, instead, during backup Bacula will
298 /home/kern/my-fifo.backup
300 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
303 /home/kern/my-fifo.restore
305 and send the data backed up to stdout. These programs can either be an
306 executable or a shell script and they need only read/write to stdin/stdout.
308 I think this would give a lot of flexibility to the user without making any
309 significant changes to Bacula.

326 === Migration from David ===
327 What I'd like to see:
330 Name = "<poolname>-migrate"
334 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
335 Client | PoolResidence | Volume | JobName | SQLquery
336 Migration Selection Pattern = "regexp"
337 Next Pool = <override>
340 There should be no need for a Level (migration is always Full, since you
341 don't calculate differential/incremental differences for migration),
342 Storage should be determined by the volume types in the pool, and Client
343 is really a selection issue. Migration should always occur to the
344 NextPool defined in the pool definition. If no nextpool is defined, the
345 job should end with a reason of "no place to go". If Next Pool statement
346 is present, we override the check in the pool definition and use the
349 Here's how I'd define Migration Selection Types:
352 Client -- Migrate data from selected client only. Migration Selection
353 Pattern regexp provides pattern to select client names, eg ^FS00* makes
354 all client names starting with FS00 eligible for migration.
356 Jobname -- Migration all jobs matching name. Migration Selection Pattern
357 regexp provides pattern to select jobnames existing in pool.
359 Volume -- Migrate all data on specified volumes. Migration Selection
360 Pattern regexp provides selection criteria for volumes to be migrated.
361 Volumes must exist in pool to be eligible for migration.
365 LowestUtil -- Identify the volume in the pool with the least data on it
366 and empty it. No Migration Selection Pattern required.
368 OldestVol -- Identify the LRU volume with data written, and empty it. No
369 Migration Selection Pattern required.
371 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
372 (starting with most full volumes) until pool occupancy drops below
373 <lowmig>. Pool highmig and lowmig values are in pool definition, no
374 Migration Selection Pattern required.
378 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
379 Migration Selection Pattern contains SQL query to execute; should return
380 a list of 1 or more jobuids to migrate.
382 PoolResidence -- Migrate data sitting in pool for longer than
383 PoolResidence value in pool definition. Migration Selection Pattern
384 optional; if specified, override value in pool definition (value in

500 - http://www.dwheeler.com/essays/commercial-floss.html
501 - Add VolumeLock to prevent all but lock holder (SD) from updating
502 the Volume data (with the exception of VolumeState).
503 - The btape fill command does not seem to use the Autochanger
504 - Make Windows installer default to system disk drive.
505 - Look at using ioctl(FIOBMAP, ...) on Linux, and
506 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
507 Win32 for sparse files.

527 - Implement a mode that says when a hard read error is
528 encountered, read many times (as it currently does), and if the
529 block cannot be read, skip to the next block, and try again. If
530 that fails, skip to the next file and try again, ...
532 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
533 insert into LevelType (LevelType,LevelTypeLong) values
537 - Show files/second in client status output.
538 - Add a recursive mark command (rmark) to restore.
539 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
540 of the same level and does not permit multiple simultaneous
541 running of that Job (i.e. lets any previous invocation finish
542 before doing Interval testing).
543 - Look at simplifying File exclusions.
544 - New directive "Delete purged Volumes"
545 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
546 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
547 see if it become stable and I just have to supervise
549 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
550 PoolId, and when it is empty remove it.
551 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
553 - Allow Check Labels to be used with Bacula labels.
554 - "Resuming" a failed backup (lost line for example) by using the
555 failed backup as a sort of "base" job.
557 - Email to the user when the tape is about to need changing x
558 days before it needs changing.
559 - Command to show next tape that will be used for a job even
560 if the job is not scheduled.
561 - From: Arunav Mandal <amandal@trolltech.com>
562 1. When jobs are running and bacula for some reason crashes or if I do a
563 restart it remembers and jobs it was running before it crashed or restarted
564 as of now I loose all jobs if I restart it.
566 2. When spooling and in the midway if client is disconnected for instance a
567 laptop bacula completely discard the spool. It will be nice if it can write
568 that spool to tape so there will be some backups for that client if not all.
570 3. We have around 150 clients machines it will be nice to have a option to
571 upgrade all the client machines bacula version automatically.
573 4. Atleast one connection should be reserved for the bconsole so at heavy load
574 I should connect to the director via bconsole which at sometimes I can't
576 5. Another most important feature that is missing, say at 10am I manually
577 started backup of client abc and it was a full backup since client abc has
578 no backup history and at 10.30am bacula again automatically started backup of
579 client abc as that was in the schedule. So now we have 2 multiple Full
580 backups of the same client and if we again try to start a full backup of
581 client backup abc bacula won't complain. That should be fixed.
583 - Fix bpipe.c so that it does not modify results pointer.
584 ***FIXME*** calling sequence should be changed.
585 - For Windows disaster recovery see http://unattended.sf.net/
586 - regardless of the retention period, Bacula will not prune the
587 last Full, Diff, or Inc File data until a month after the
588 retention period for the last Full backup that was done.
589 - update volume=xxx --- add status=Full
590 - Remove old spool files on startup.
591 - Exclude SD spool/working directory.
592 - Refuse to prune last valid Full backup. Same goes for Catalog.
594 - Make a callback when Rerun failed levels is called.
595 - Give Python program access to Scheduled jobs.
596 - Add setting Volume State via Python.
597 - Python script to save with Python, not save, save with Bacula.
598 - Python script to do backup.
600 - Change the Priority, Client, Storage, JobStatus (error)
601 at the start of a job.
602 - Why is SpoolDirectory = /home/bacula/spool; not reported
603 as an error when writing a DVD?
604 - Make bootstrap file handle multiple MediaTypes (SD)
605 - Remove all old Device resource code in Dir and code to pass it
606 back in SD -- better, rework it to pass back device statistics.
607 - Check locking of resources -- be sure to lock devices where previously
608 resources were locked.
609 - The last part is left in the spool dir.
612 - In restore don't compare byte count on a raw device -- directory
613 entry does not contain bytes.
617 MA = (last_MA * 3 + rate) / 4
618 rate = (bytes - last_bytes) / (runtime - last_runtime)
619 - Max Vols limit in Pool off by one?
620 - Implement Files/Bytes,... stats for restore job.
621 - Implement Total Bytes Written, ... for restore job.
622 - Despool attributes simultaneously with data in a separate
623 thread, rejoined at end of data spooling.
624 - 7. Implement new Console commands to allow offlining/reserving drives,
625 and possibly manipulating the autochanger (much asked for).
626 - Add start/end date editing in messages (%t %T, %e?) ...
627 - Add ClientDefs similar to JobDefs.
628 - Print more info when bextract -p accepts a bad block.
629 - Fix FD JobType to be set before RunBeforeJob in FD.
630 - Look at adding full Volume and Pool information to a Volume
631 label so that bscan can get *all* the info.
632 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
633 and there is only one volume in the pool, refuse to do it -- otherwise
634 he fills the Volume, then immediately starts reusing it.
635 - Implement copies and stripes.
636 - Add history file to console.
637 - Each file on tape creates a JobMedia record. Peter has 4 million
638 files spread over 10000 tape files and four tapes. A restore takes
639 16 hours to build the restore list.
640 - Add and option to check if the file size changed during backup.
641 - Make sure SD deletes spool files on error exit.
642 - Delete old spool files when SD starts.
643 - When labeling tapes, if you enter 000026, Bacula uses
644 the tape index rather than the Volume name 000026.
645 - Add offline tape command to Bacula console.
647 Enter MediaId or Volume name: 32
648 Enter new Volume name: DLT-20Dec04
649 Automatically selected Pool: Default
650 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

657 Label command failed for Volume DLT-20Dec04.
658 Do not forget to mount the drive!!!
659 - Bug: if a job is manually scheduled to run later, it does not appear
660 in any status report and cannot be cancelled.
662 ==== Keeping track of deleted/new files ====
663 - To mark files as deleted, run essentially a Verify to disk, and
664 when a file is found missing (MarkId != JobId), then create
665 a new File record with FileIndex == -1. This could be done
666 by the FD at the same time as the backup.
668 My "trick" for keeping track of deletions is the following.
669 Assuming the user turns on this option, after all the files
670 have been backed up, but before the job has terminated, the
671 FD will make a pass through all the files and send their
672 names to the DIR (*exactly* the same as what a Verify job
673 currently does). This will probably be done at the same
674 time the files are being sent to the SD avoiding a second
675 pass. The DIR will then compare that to what is stored in
676 the catalog. Any files in the catalog but not in what the
677 FD sent will receive a catalog File entry that indicates
678 that at that point in time the file was deleted. This
679 either transmitted to the FD or simultaneously computed in
680 the FD, so that the FD can put a record on the tape that
681 indicates that the file has been deleted at this point.
682 A delete file entry could potentially be one with a FileIndex
683 of 0 or perhaps -1 (need to check if FileIndex is used for
684 some other thing as many of the Bacula fields are "overloaded"
687 During a restore, any file initially picked up by some
688 backup (Full, ...) then subsequently having a File entry
689 marked "delete" will be removed from the tree, so will not
690 be restored. If a file with the same name is later OK it
691 will be inserted in the tree -- this already happens. All
692 will be consistent except for possible changes during the
695 Since I'm on the subject, some of you may be wondering what
696 the utility of the in memory tree is if you are going to
697 restore everything (at least it comes up from time to time
698 on the list). Well, it is still *very* useful because it
699 allows only the last item found for a particular filename
700 (full path) to be entered into the tree, and thus if a file
701 is backed up 10 times, only the last copy will be restored.
702 I recently (last Friday) restored a complete directory, and
703 the Full and all the Differential and Incremental backups
704 spanned 3 Volumes. The first Volume was not even mounted
705 because all the files had been updated and hence backed up
706 since the Full backup was made. In this case, the tree
707 saved me a *lot* of time.
709 Make sure this information is stored on the tape too so
710 that it can be restored directly from the tape.
712 All the code (with the exception of formally generating and
713 saving the delete file entries) already exists in the Verify
714 Catalog command. It explicitly recognizes added/deleted files since
715 the last InitCatalog. It is more or less a "simple" matter of
716 taking that code and adapting it slightly to work for backups.
718 Comments from Martin Simmons (I think they are all covered):
719 Ok, that should cover the basics. There are few issues though:
721 - Restore will depend on the catalog. I think it is better to include the
722 extra data in the backup as well, so it can be seen by bscan and bextract.
724 - I'm not sure if it will preserve multiple hard links to the same inode. Or
725 maybe adding or removing links will cause the data to be dumped again?
727 - I'm not sure if it will handle renamed directories. Possibly it will work
728 by dumping the whole tree under a renamed directory?
730 - It remains to be seen how the backup performance of the DIR's will be
731 affected when comparing the catalog for a large filesystem.
735 How about introducing a Type = MgmtPolicy job type? That job type would
736 be responsible for scanning the Bacula environment looking for specific
737 conditions, and submitting the appropriate jobs for implementing said
741 Name = "Migration-Policy"
743 Policy Selection Job Type = Migrate
744 Scope = "<keyword> <operator> <regexp>"
745 Threshold = "<keyword> <operator> <regexp>"
746 Job Template = <template-name>
749 Where <keyword> is any legal job keyword, <operator> is a comparison
750 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
751 appropriate regexp. I could see an argument for Scope and Threshold
752 being SQL queries if we want to support full flexibility. The
753 Migration-Policy job would then get scheduled as frequently as a site
754 felt necessary (suggested default: every 15 minutes).
759 Name = "Migration-Policy"
761 Policy Selection Job Type = Migration
763 Threshold = "Migration Selection Type = LowestUtil"
764 Job Template = "MigrationTemplate"
767 would select all pools for examination and generate a job based on
768 MigrationTemplate to automatically select the volume with the lowest
769 usage and migrate it's contents to the nextpool defined for that pool.
771 This policy abstraction would be really handy for adjusting the behavior
772 of Bacula according to site-selectable criteria (one thing that pops
773 into mind is Amanda's ability to automatically adjust backup levels
774 depending on various criteria).
780 - Add Pool/Storage override regression test.
781 - Add delete JobId to regression.
782 - Add a regression test for dbcheck.
783 - New test to add bscan to four-concurrent-jobs regression,
784 i.e. after the four-concurrent jobs zap the
785 database as is done in the bscan-test, then use bscan to
786 restore the database, do a restore and compare with the
788 - Add restore of specific JobId to regression (item 3
789 on the restore prompt)
790 - Add IPv6 to regression
791 - Add database test to regression. Test each function like delete,
794 - AntiVir can slow down backups on Win32 systems.
795 - Win32 systems with FAT32 can be much slower than NTFS for
796 more than 1000 files per directory.
800 - A HOLD command to stop all jobs from starting.
801 - A PAUSE command to pause all running jobs ==> release the

805 Media Type Write = LTO2, LTO3
807 === From Carsten Menke <bootsy52@gmx.net>
809 Following is a list of what I think in the situations where I'm faced with,
810 could be a usefull enhancement to bacula, which I'm certain other users will
811 benefit from as well.
813 1. NextJob/NextJobs Directive within a Job Resource in the form of
814 NextJobs = job1,job2.
817 I currently solved the problem with running multiple jobs each after each
818 by setting the Max Wait Time for a job to 8 hours, and give
819 the jobs different Priorities. However, there scenarios where
820 1 Job is directly depending on another job, so if the former job fails,
821 the job after it needn't to be run
822 while maybe other jobs should run despite of that
825 A Backup Job and a Verify job, if the backup job fails there is no need to run
826 the verify job, as the backup job already failed. However, one may like
827 to backup the Catalog to disk despite of that the main backup job failed.
830 I see that this is related to the Event Handlers which are on the ToDo
831 list, also it is maybe a good idea to check for the return value and
832 execute different actions based on the return value
835 3. offline capability to bconsole
838 Currently I use a script which I execute within the last Job via the
839 RunAfterJob Directive, to release and eject the tape.
840 So I have to call bconsole "release=Storage-Name" and afterwards
841 mt -f /dev/nst0 eject to get the tape out.
843 If I have multiple Storage Devices, than these may not be /dev/nst0 and
844 I have to modify the script or call it with parameters etc.
845 This would actually not be needed, as everything is already defined
846 in bacula-sd.conf and if I can invoke bconsole with the
847 storage name via $1 in the script than I'm done and information is
850 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
854 For the reason mentioned in 3. to have the ability to call a
855 script with /scripts/foobar %s and in the script use $1
856 to pass the Storage Name to bconsole
858 5. Setting Volume State within a Job Resource
861 Instead of using "Maximum Volume Jobs" in the Pool Resource,
862 I would have the possibilty to define
863 in a Job Resource that after this certain job is run, the Volume State
864 should be set to "Volume State = Used", this give more flexibility (IMHO).
866 6. Localization of Bacula Messages
869 Unfortunatley many,many people I work with don't speak english very well.
870 So if at least the Reporting messages would be localized then they
871 would understand that they have to change the tape,etc. etc.
873 I volunteer to do the german translations, and if I can convince my wife also
874 french and Morre (western african language).
876 7. OK, this is evil, probably bound to security risks and maybe not possible
877 due to the design of bacula.
879 Implementation of Backtics ( `command` ) for shell comand execution to
880 the "Label Format" Directive.
884 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
885 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
886 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
887 the localized name for the day of the week appended to the
888 format string. Then I have the tape labeled automatically with weekday
889 name in the correct language.
891 - Yes, that is surely the case. I probably should turn those into Warning
892 errors. In addition, you just made me think that it might not be bad to
893 add an option to check the file size after backing up the file and
894 report if it changes. This would be done as an option because it would
897 Kern, good idea. If you do do that, mention in the output: file
898 shrunk, or file expanded, just to make it obvious to the user
899 (without having to the refer to file size), just how the file size
902 Would this option be for all file, or just one file? Or a fileset?
903 - Make output from status use html table tags for nicely
904 presenting in a browser.
905 - Can one write tapes faster with 8192 byte block sizes?
906 - Document security problems with the same password for everyone in
907 rpm and Win32 releases.
908 - Browse generations of files.
909 - I've seen an error when my catalog's File table fills up. I
910 then have to recreate the File table with a larger maximum row
911 size. Relevant information is at
912 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
913 "Installing and Configuring MySQL" chapter should talk a bit
914 about this potential problem, and recommend a solution.
915 - For Solaris must use POSIX awk.
916 - Want speed of writing to tape while despooling.
917 - Supported autochanger:
925 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
926 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
927 - Add regex from http://www.pcre.org to Bacula for Win32.
928 - Use only shell tools no make in CDROM package.
929 - Include within include does it work?
930 - Implement a Pool of type Cleaning?
931 - Implement VolReadTime and VolWriteTime in SD
932 - Modify Backing up Your Database to include a bootstrap file.
933 - Think about making certain database errors fatal.
934 - Look at correcting the time jump in the scheduler for daylight
935 savings time changes.
936 - Add a "real" timer to network connections.
937 - Promote to Full = Time period
938 - Check dates entered by user for correctness (month/day/... ranges)
939 - Compress restore Volume listing by date and first file.
940 - Look at patches/bacula_db.b2z postgresql that loops during restore.
942 - Perhaps add read/write programs and/or plugins to FileSets.
943 - How to handle backing up portables ...
944 - Add some sort of guaranteed Interval for upgrading jobs.
945 - Can we write the state file after every job terminates? On Win32
946 the system crashes and the state file is not updated.
949 Documentation to do: (any release a little bit at a time)
950 - Doc to do unmount before removing magazine.
951 - Alternative to static linking "ldd prog" save all binaries listed,
952 restore them and point LD_LIBRARY_PATH to them.
953 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
954 - Document query file format.
955 - Add more documentation for bsr files.
956 - Document problems with Verify and pruning.
957 - Document how to use multiple databases.
958 - VXA drives have a "cleaning required"
959 indicator, but Exabyte recommends preventive cleaning after every 75
962 In this context, it should be noted that Exabyte has a command-line
963 vxatool utility available for free download. (The current version is
964 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
965 test the drive, unload tapes, change drive settings, flash new firmware,
967 Of particular interest in this context is that vxatool <device> -i will
968 report, among other details, the time since last cleaning in tape motion
969 minutes. This information can be retrieved (and settings changed, for
970 that matter) through the generic-SCSI device even when Bacula has the
971 regular tape device locked. (Needless to say, I don't recommend
972 changing tape settings while a job is running.)
973 - Lookup HP cleaning recommendations.
974 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
975 - Document doing table repair
978 ===================================
979 - Add macro expansions in JobDefs.
980 Run Before Job = "SomeFile %{Level} %{Client}"
981 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
982 - Use non-blocking network I/O but if no data is available, use
984 - Use gather write() for network I/O.
985 - Autorestart on crash.
986 - Add bandwidth limiting.
987 - Add acks every once and a while from the SD to keep
988 the line from timing out.
989 - When an error in input occurs and conio beeps, you can back
990 up through the prompt.
991 - Detect fixed tape block mode during positioning by looking at
992 block numbers in btape "test". Possibly adjust in Bacula.
993 - Fix list volumes to output volume retention in some other
994 units, perhaps via a directive.
995 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
996 with multiple priorities.
997 - If you use restore replace=never, the directory attributes for
998 non-existent directories will not be restored properly.
1000 - see lzma401.zip in others directory for new compression
1002 - Allow the user to select JobType for manual pruning/purging.
1003 - bscan does not put first of two volumes back with all info in
1005 - Implement the FreeBSD nodump flag in chflags.
1006 - Figure out how to make named console messages go only to that
1007 console and to the non-restricted console (new console class?).
1008 - Make restricted console prompt for password if *ask* is set or
1009 perhaps if password is undefined.
1010 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1013 ==== from Marc Schoechlin
1014 - the help-command should be more verbose
1015 (it should explain the paramters of the different
1017 -> its time-comsuming to consult the manual anytime
1018 you need a special parameter
1019 -> maybe its more easy to maintain this, if the
1020 descriptions of that commands are outsourced to
1022 - the cd-command should allow complete paths
1023 i.e. cd /foo/bar/foo/bar
1024 -> if a customer mails me the path to a certain file,
1025 its faster to enter the specified directory
1026 - if the password is not configured in bconsole.conf
1027 you should be asked for it.
1028 -> sometimes you like to do restore on a customer-machine
1029 which shouldnt know the password for bacula.
1030 -> adding the password to the file favours admins
1031 to forget to remove the password after usage
1033 the protection of that file is less important
1034 - long-listed-output of commands should be scrollable
1035 like the unix more/less-command does
1036 -> if someone runs 200 and more machines, the lists could
1037 be a little long and complex
1038 - command-output should be shown column by column
1039 to reduce scrolling and to increase clarity
1041 - lsmark should list the selected files with full
1043 - wildcards for selecting and file and directories would be nice
1044 - any actions should be interuptable with STRG+C
1045 - command-expansion would be pretty cool
1047 - When the replace Never option is set, new directory permissions
1048 are not restored. See bug 213. To fix this requires creating a
1049 list of newly restored directories so that those directory
1050 permissions *can* be restored.
1051 - Add prune all command
1052 - Document fact that purge can destroy a part of a restore by purging
1053 one volume while others remain valid -- perhaps mark Jobs.
1054 - Add multiple-media-types.txt
1055 - look at mxt-changer.html
1056 - Make ? do a help command (no return needed).
1057 - Implement restore directory.
1058 - Document streams and how to implement them.
1059 - Try not to re-backup a file if a new hard link is added.
1060 - Add feature to backup hard links only, but not the data.
1061 - Fix stream handling to be simpler.
1062 - Add Priority and Bootstrap to Run a Job.
1063 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1065 - Remove View FileSet button from Run a Job dialog.
1066 - Handle prompt for restore job at end of Restore command.
1067 - Add display of total selected files to Restore window.
1068 - Add tree pane to left of window.
1069 - Add progress meter.
1070 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1071 - Add message to user to check for fixed block size when the forward
1072 space test fails in btape.
1073 - When unmarking a directory check if all files below are unmarked and
1074 then remove the + flag -- in the restore tree.
1075 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1076 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1077 - Revisit the question of multiple Volumes (disk) on a single device.
1078 - Add a block copy option to bcopy.
1079 - Finish work on Gnome restore GUI.
1080 - Fix "llist jobid=xx" where no fileset or client exists.
1081 - For each job type (Admin, Restore, ...) require only the really necessary
1082 fields.- Pass Director resource name as an option to the Console.
1083 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1084 - Add a .list all files in the restore tree (probably also a list all files)
1085 Do both a long and short form.
1086 - Allow browsing the catalog to see all versions of a file (with
1087 stat data on each file).
1088 - Restore attributes of directory if replace=never set but directory
1090 - Use SHA1 on authentication if possible.
1091 - See comtest-xxx.zip for Windows code to talk to USB.
1092 - Add John's appended files:
1093 Appended = { /files/server/logs/http/*log }
1094 and such files would be treated as follows.On a FULL backup, they would
1095 be backed up like any other file.On an INCREMENTAL backup, where a
1096 previous INCREMENTAL or FULL was already in thecatalogue and the length
1097 of the file wasgreater than the length of the last backup, only thedata
1098 added since the last backup will be dumped.On an INCREMENTAL backup, if
1099 the length of the file is less than thelength of the file with the same
1100 name last backed up, the completefile is dumped.On Windows systems, with
1101 creation date of files, we can be evensmarter about this and not count
1102 entirely upon the length.On a restore, the full and all incrementals
1103 since it will beapplied in sequence to restore the file.
1104 - Check new HAVE_WIN32 open bits.
1105 - Check if the tape has moved before writing.
1106 - Handling removable disks -- see below:
1107 - Keep track of tape use time, and report when cleaning is necessary.
1108 - Add FromClient and ToClient keywords on restore command (or
1109 BackupClient RestoreClient).
1110 - Implement a JobSet, which groups any number of jobs. If the
1111 JobSet is started, all the jobs are started together.
1112 Allow Pool, Level, and Schedule overrides.
1113 - Enhance cancel to timeout BSOCK packets after a specific delay.
1114 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1115 ua_status.!!! Thanks to Alan Brown for this tip.
1116 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1117 correctly for multiple simultaneous jobs.
1118 - Correct code so that FileSet MD5 is calculated for < and | filename
1120 - Implement the Media record flag that indicates that the Volume does disk
1122 - Implement VolAddr, which is used when Volume is addressed like a disk,
1123 and form it from VolFile and VolBlock.
1124 - Make multiple restore jobs for multiple media types specifying
1125 the proper storage type.
1126 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1127 pointer (rec) to try_repositioning().
1128 - Look at extracting Win data from BackupRead.
1129 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1130 which would take precidence over the Catalog "JobRetention".
1131 - Implement Label Format in Add and Label console commands.
1132 - Possibly up network buffers to 65K. Put on variable.
1133 - Put email tape request delays on one or more variables. User wants
1134 to cancel the job after a certain time interval. Maximum Mount Wait?
1135 - Job, Client, Device, Pool, or Volume?
1136 Is it possible to make this a directive which is *optional* in multiple
1137 resources, like Level? If so, I think I'd make it an optional directive
1138 in Job, Client, and Pool, with precedence such that Job overrides Client
1139 which in turn overrides Pool.
1141 - New Storage specifications:
1142 - Want to write to multiple storage devices simultaneously
1143 - Want to write to multiple storage devices sequentially (in one job)
1144 - Want to read/write simultaneously
1145 - Key is MediaType -- it must match
1147 Passed to SD as a sort of BSR record called Storage Specification
1151 MediaType -> Next MediaType
1153 Device -> Next Device
1155 Allow multiple Storage specifications
1163 Allow Multiple Pool specifications (note, Pool currently
1165 Allow Multiple MediaType specifications in Dir conf
1166 Allow Multiple Device specifications in Dir conf
1167 Perhaps keep this in a single SSR
1168 Tie a Volume to a specific device by using a MediaType that
1169 is contained in only one device.
1170 In SD allow Device to have Multiple MediaTypes
1172 - Ideas from Jerry Scharf:
1173 First let's point out some big pluses that bacula has for this
1175 more importantly it's active. Thank you so much for that
1176 even more important, it's not flaky
1177 it has an open access catalog, opening many possibilities
1178 it's pushing toward heterogeneous systems capability
1180 Macintosh file client
1181 macs are an interesting niche, but I fear a server is a rathole
1182 working bare iron recovery for windows
1183 the option for inc/diff backups not reset on fileset revision
1184 a) use both change and inode update time against base time
1185 b) do the full catalog check (expensive but accurate)
1186 sizing guide (how much system is needed to back up N systems/files)
1187 consultants on using bacula in building a disaster recovery system
1188 an integration guide
1189 or how to get at fancy things that one could do with bacula
1190 logwatch code for bacula logs (or similar)
1191 linux distro inclusion of bacula (brings good and bad, but necessary)
1192 win2k/XP server capability (icky but you asked)
1193 support for Oracle database ??
1195 - Look at adding SQL server and Exchange support for Windows.
1196 - Make dev->file and dev->block_num signed integers so that -1 can
1197 be an invalid value which happens with BSR.
1198 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1199 is needed to properly specify ranges.
1200 - Add progress of files/bytes to SD and FD.
1201 - Print warning message if FileId > 4 billion
1202 - do a "messages" before the first prompt in Console
1203 - Client does not show busy during Estimate command.
1204 - Implement Console mtx commands.
1205 - Implement a Mount Command and an Unmount Command where
1206 the users could specify a system command to be performed
1207 to do the mount, after which Bacula could attempt to
1208 read the device. This is for Removeable media such as a CDROM.
1209 - Most likely, this mount command would be invoked explicitly
1210 by the user using the current Console "mount" and "unmount"
1211 commands -- the Storage Daemon would do the right thing
1212 depending on the exact nature of the device.
1213 - As with tape drives, when Bacula wanted a new removable
1214 disk mounted, it would unmount the old one, and send a message
1215 to the user, who would then use "mount" as described above
1216 once he had actually inserted the disk.
1217 - Implement dump/print label to UA
1218 - Spool to disk only when the tape is full, then when a tape is hung move
1220 - bextract is sending everything to the log file ****FIXME****
1221 - Allow multiple Storage specifications (or multiple names on
1222 a single Storage specification) in the Job record. Thus a job
1223 can be backed up to a number of storage devices.
1224 - Implement some way for the File daemon to contact the Director
1225 to start a job or pass its DHCP obtained IP number.
1226 - Implement a query tape prompt/replace feature for a console
1227 - Copy console @ code to gnome2-console
1228 - Make tree walk routines like cd, ls, ... more user friendly
1229 by handling spaces better.
1230 - Make sure that Bacula rechecks the tape after the 20 min wait.
1231 - Set IO_NOWAIT on Bacula TCP/IP packets.
1232 - Try doing a raw partition backup and restore by mounting a
1234 - From Lars Kellers:
1235 Yes, it would allow to highly automatic the request for new tapes. If a
1236 tape is empty, bacula reads the barcodes (native or simulated), and if
1237 an unused tape is found, it runs the label command with all the
1238 necessary parameters.
1240 By the way can bacula automatically "move" an empty/purged volume say
1241 in the "short" pool to the "long" pool if this pool runs out of volume
1243 - What to do about "list files job=xxx".
1244 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1245 file descriptor leak in Bacula.
1246 - Implement WrapCounters in Counters.
1247 - Add heartbeat from FD to SD if hb interval expires.
1248 - Can we dynamically change FileSets?
1249 - If pool specified to label command and Label Format is specified,
1250 automatically generate the Volume name.
1251 - Why can't SQL do the filename sort for restore?
1252 - Add ExhautiveRestoreSearch
1253 - Look at the possibility of loading only the necessary
1254 data into the restore tree (i.e. do it one directory at a
1255 time as the user walks through the tree).
1256 - Possibly use the hash code if the user selects all for a restore command.
1257 - Fix "restore all" to bypass building the tree.
1258 - Prohibit backing up archive device (findlib/find_one.c:128)
1259 - Implement Release Device in the Job resource to unmount a drive.
1260 - Implement Acquire Device in the Job resource to mount a drive,
1261 be sure this works with admin jobs so that the user can get
1262 prompted to insert the correct tape. Possibly some way to say to
1263 run the job but don't save the files.
1264 - Make things like list where a file is saved case independent for
1266 - Use autochanger to handle multiple devices.
1267 - Implement a Recycle command
1268 - Start working on Base jobs.
1269 - Implement UnsavedFiles DB record.
1270 - From Phil Stracchino:
1271 It would probably be a per-client option, and would be called
1272 something like, say, "Automatically purge obsoleted jobs". What it
1273 would do is, when you successfully complete a Differential backup of a
1274 client, it would automatically purge all Incremental backups for that
1275 client that are rendered redundant by that Differential. Likewise,
1276 when a Full backup on a client completed, it would automatically purge
1277 all Differential and Incremental jobs obsoleted by that Full backup.
1278 This would let people minimize the number of tapes they're keeping on
1279 hand without having to master the art of retention times.
1280 - When doing a Backup send all attributes back to the Director, who
1281 would then figure out what files have been deleted.
1282 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1283 explicit permission to do so. It should also mark the tape in error
1284 if there is an error.
1285 - Cancel waiting for Client connect in SD if FD goes away.
1287 - Implement timeout in response() when it should come quickly.
1288 - Implement a Slot priority (loaded/not loaded).
1289 - Implement "vacation" Incremental only saves.
1290 - Implement create "FileSet"?
1291 - Add prefixlinks to where or not where absolute links to FD.
1292 - Issue message to mount a new tape before the rewind.
1293 - Simplified client job initiation for portables.
1294 - If SD cannot open a drive, make it periodically retry.
1295 - Add more of the config info to the tape label.
1297 - Refine SD waiting output:
1298 Device is being positioned
1299 > Device is being positioned for append
1300 > Device is being positioned to file x
1302 - Figure out some way to estimate output size and to avoid splitting
1303 a backup across two Volumes -- this could be useful for writing CDROMs
1304 where you really prefer not to have it split -- not serious.
1305 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1306 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1307 actual data on the Volume and compare it.
1308 - Implement Bacula plugins -- design API
1309 - Make bcopy read through bad tape records.
1310 - Program files (i.e. execute a program to read/write files).
1311 Pass read date of last backup, size of file last time.
1312 - Add Signature type to File DB record.
1313 - CD into subdirectory when open()ing files for backup to
1314 speed up things. Test with testfind().
1315 - Priority job to go to top of list.
1316 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1317 - Implement some way for the Console to dynamically create a job.
1318 - Solaris -I on tar for include list
1319 - Need a verbose mode in restore, perhaps to bsr.
1320 - bscan without -v is too quiet -- perhaps show jobs.
1321 - Add code to reject whole blocks if not wanted on restore.
1322 - Check if we can increase Bacula FD priorty in Win2000
1323 - Make sure the MaxVolFiles is fully implemented in SD
1324 - Check if both CatalogFiles and UseCatalog are set to SD.
1325 - Possibly add email to Watchdog if drive is unmounted too
1326 long and a job is waiting on the drive.
1327 - After unmount, if restore job started, ask to mount.
1328 - Add UA rc and history files.
1329 - put termcap (used by console) in ./configure and
1330 allow -with-termcap-dir.
1331 - Fix Autoprune for Volumes to respect need for full save.
1332 - Compare tape to Client files (attributes, or attributes and data)
1333 - Make all database Ids 64 bit.
1334 - Allow console commands to detach or run in background.
1335 - Add SD message variables to control operator wait time
1336 - Maximum Operator Wait
1337 - Minimum Message Interval
1338 - Maximum Message Interval
1339 - Send Operator message when cannot read tape label.
1340 - Verify level=Volume (scan only), level=Data (compare of data to file).
1341 Verify level=Catalog, level=InitCatalog
1343 - Add keyword search to show command in Console.
1344 - Events : tape has more than xxx bytes.
1345 - Complete code in Bacula Resources -- this will permit
1346 reading a new config file at any time.
1347 - Handle ctl-c in Console
1348 - Implement script driven addition of File daemon to config files.
1349 - Think about how to make Bacula work better with File (non-tape) archives.
1350 - Write Unix emulator for Windows.
1351 - Put memory utilization in Status output of each daemon
1352 if full status requested or if some level of debug on.
1353 - Make database type selectable by .conf files i.e. at runtime
1354 - Set flag for uname -a. Add to Volume label.
1355 - Restore files modified after date
1356 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1357 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1358 - Timout a job or terminate if link goes down, or reopen link and query.
1359 - Concept of precious tapes (cannot be reused).
1360 - Make bcopy copy with a single tape drive.
1361 - Permit changing ownership during restore.

1375 - Autolabel should be specified by DIR instead of SD.
1377 - Add media capacity
1378 - AutoScan (check checksum of tape)
1379 - Format command = "format /dev/nst0"
1383 - Seek resolution (usually corresponds to buffer size)
1384 - EODErrorCode=ENOSPC or code
1385 - Partial Read error code
1386 - Partial write error code
1387 - Nonformatted read error
1388 - Nonformatted write error
1389 - WriteProtected error
1393 - IgnoreCloseErrors=yes
1403 - FD sends unsaved file list to Director at end of job (see
1405 - File daemon should build list of files skipped, and then
1406 at end of save retry and report any errors.
1407 - Write a Storage daemon that uses pipes and
1408 standard Unix programs to write to the tape.
1410 - Need something that monitors the JCR queue and
1411 times out jobs by asking the deamons where they are.
1412 - Enhance Jmsg code to permit buffering and saving to disk.
1413 - device driver = "xxxx" for drives.
1414 - Verify from Volume
1415 - Ensure that /dev/null works
1416 - Need report class for messages. Perhaps
1417 report resource where report=group of messages
1418 - enhance scan_attrib and rename scan_jobtype, and
1419 fill in code for "since" option
1420 - Director needs a time after which the report status is sent
1421 anyway -- or better yet, a retry time for the job.
1422 - Don't reschedule a job if previous incarnation is still running.
1423 - Some way to automatically backup everything is needed????
1424 - Need a structure for pending actions:
1426 - termination status (part of buffered msgs?)
1428 Read, Write, Clean, Delete
1429 - Login to Bacula; Bacula users with different permissions:
1430 owner, group, user, quotas
1431 - Store info on each file system type (probably in the job header on tape.
1432 This could be the output of df; or perhaps some sort of /etc/mtab record.

1435 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1436 To: <kern@sibbald.com>
1437 Subject: RE: [Bacula-users] future large programming jobs
1438 Date: Thu, 26 Feb 2004 11:34:54 -0600
1440 I noticed the subject thread and thought I would offer the following
1441 merely as sources of ideas, i.e. something to think about, not even as
1442 strong as a request. In my former life (before retiring) I often
1443 dealt with backups and storage management issues/products as a
1444 developer and as a consultant. I am currently migrating my personal
1445 network from amanda to bacula specifically because of the ability to
1446 cross media boundaries during storing backups.
1447 Are you familiar with the commercial product called ADSM (I think IBM
1448 now sells it under the Tivoli label)? It has a couple of interesting
1449 ideas that may apply to the following topics.
1451 1. Migration: Consider that when you need to restore a system, there
1452 may be pressure to hurry. If all the information for a single client
1453 can eventually end up on the same media (and in chronological order),
1454 the restore is facillitated by not having to search past information
1455 from other clients. ADSM has the concept of "client affinity" that
1456 may be associated with it's storage pools. It seems to me that this
1457 concept (as an optional feature) might fit in your architecture for
1460 ADSM also has the concept of defining one or more storage pools as
1461 "copy pools" (almost mirrors, but only in the sense of contents).
1462 These pools provide the ability to have duplicte data stored both
1463 onsite and offsite. The copy process can be scheduled to be handled
1464 by their storage manager during periods when there is no backup
1465 activity. Again, the migration process might be a place to consider
1466 implementing something like this.
1469 > It strikes me that it would be very nice to be able to do things
1471 > have the Job(s) backing up the machines run, and once they have all

1477 > mechanism described below would probably make it very easy.
1479 This is the goal. In the first step (before events), you simply
1481 the Migration to tape later.
1483 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1484 the database. Once a file (unique by path and metadata such as dates,
1485 size, ownership, etc.) is in a copy pool, no more copies are made. In
1486 other words, when you start ADSM, it begins like your concept of a
1487 base job. After that it is in the "incremental" mode. You can
1488 configure the number of "generations" of files to be retained, plus a
1489 retention date after which even old generations are purged. The
1490 database tracks the contents of media and projects the percentage of
1491 each volume that is valid. When the valid content of a volume drops
1492 below a configured percentage, the valid data are migrated to another
1493 volume and the old volume is marked as empty. Note, this requires
1494 ADSM to have an idea of the contents of a client, i.e. marking the
1495 database when an existing file was deleted, but this would solve your
1496 issue of restoring a client without restoring deleted files.
1498 This is pretty far from what bacula now does, but if you are going to
1499 rip things up for Base jobs,.....
1500 Also, the benefits of this are huge for very large shops, especially
1501 with media robots, but are a pain for shops with manual media
1505 > Base jobs sound pretty useful, but I'm not dying for them.
1507 Nobody is dying for them, but when you see what it does, you will die
1510 3. Restoring deleted files: Since I think my comments in (2) above
1511 have low probability of implementation, I'll also suggest that you
1512 could approach the issue of deleted files by a mechanism of having the
1513 fd report to the dir, a list of all files on the client for every
1514 backup job. The dir could note in the database entry for each file
1515 the date that the file was seen. Then if a restore as of date X takes
1516 place, only files that exist from before X until after X would be
1517 restored. Probably the major cost here is the extra date container in
1518 each row of the files table.
1520 Thanks for "listening". I hope some of this helps. If you want to
1521 contact me, please send me an email - I read some but not all of the
1522 mailing list traffic and might miss a reply there.
1524 Please accept my compliments for bacula. It is doing a great job for
1525 me!! I sympathize with you in the need to wrestle with excelence in
1526 execution vs. excelence in feature inclusion.
1531 ==============================
1534 - Design at hierarchial storage for Bacula. Migration and Clone.
1535 - Implement FSM (File System Modules).
1536 - Audit M_ error codes to ensure they are correct and consistent.
1537 - Add variable break characters to lex analyzer.
1538 Either a bit mask or a string of chars so that
1539 the caller can change the break characters.
1540 - Make a single T_BREAK to replace T_COMMA, etc.
1541 - Ensure that File daemon and Storage daemon can
1542 continue a save if the Director goes down (this
1543 is NOT currently the case). Must detect socket error,
1544 buffer messages for later.
1545 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1546 - Add ability to backup to two Storage devices (two SD sessions) at
1547 the same time -- e.g. onsite, offsite.
1548 - Add the ability to consolidate old backup sets (basically do a restore
1549 to tape and appropriately update the catalog). Compress Volume sets.
1550 Might need to spool via file is only one drive is available.
1551 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1552 someway to do so with every volume that has less than x% valid
1556 Migration: Move a backup from one Volume to another
1557 Clone: Copy a backup -- two Volumes
1560 ======================================================
1562 It is somewhat like a Full save becomes an incremental since
1563 the Base job (or jobs) plus other non-base files.
1565 - A Base backup is same as Full backup, just different type.
1566 - New BaseFiles table that contains:
1568 BaseJobId - Base JobId referenced for this FileId (needed ???)
1569 JobId - JobId currently running
1570 FileId - File not backed up, exists in Base Job
1571 FileIndex - FileIndex from Base Job.
1572 i.e. for each base file that exists but is not saved because
1573 it has not changed, the File daemon sends the JobId, BaseId,
1574 FileId, FileIndex back to the Director who creates the DB entry.
1575 - To initiate a Base save, the Director sends the FD
1576 the FileId, and full filename for each file in the Base.
1577 - When the FD finds a Base file, he requests the Director to
1578 send him the full File entry (stat packet plus MD5), or
1579 conversely, the FD sends it to the Director and the Director
1580 says yes or no. This can be quite rapid if the FileId is kept
1581 by the FD for each Base Filename.
1582 - It is probably better to have the comparison done by the FD
1583 despite the fact that the File entry must be sent across the
1585 - An alternative would be to send the FD the whole File entry
1586 from the start. The disadvantage is that it requires a lot of
1587 space. The advantage is that it requires less communications
1589 - The Job record must be updated to indicate that one or more
1591 - At end of Job, FD returns:
1592 1. Count of base files/bytes not written to tape (i.e. matches)
1593 2. Count of base file that were saved i.e. had changed.
1594 - No tape record would be written for a Base file that matches, in the
1595 same way that no tape record is written for Incremental jobs where
1596 the file is not saved because it is unchanged.
1597 - On a restore, all the Base file records must explicitly be
1598 found from the BaseFile tape. I.e. for each Full save that is marked
1599 to have one or more Base Jobs, search the BaseFile for all occurrences
1601 - An optimization might be to make the BaseFile have:
1607 This would avoid the need to explicitly fetch each File record for
1608 the Base job. The Base Job record will be fetched to get the
1609 VolSessionId and VolSessionTime.
1610 =========================================================
1613 ==========================================================
1615 For each Incremental job that is run, there may be files that
1616 were found but not saved because they were locked (this applies
1617 only to Windows). Such a system could send back to the Director
1618 a list of Unsaved files.
1620 - New UnSavedFiles table that contains:
1624 - Then in the next Incremental job, the list of Unsaved Files will be
1625 feed to the FD, who will ensure that they are explicitly chosen even
1626 if standard date/time check would not have selected them.
1627 =============================================================

1668 (just to verify it remembers where it came from, however it can be

1671 There needs to be a table of drive # to devices somewhere - If there are
1672 multiple changers or drives there may not be a 1:1 correspondance between
1673 changer drive number and system device name - and depending on the way the
1674 drives are hooked up to scsi busses, they may not be linearly numbered
1675 from an offset point either.something like
1677 Autochanger drives = 2
1678 Autochanger drive 0 = /dev/nst1
1679 Autochanger drive 1 = /dev/nst2
1680 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1681 times, not just for multidrive changers. For a 1 drive changer, that's
1687 MTX's manpage (1.2.15):
1688 unload [<slotnum>] [ <drivenum> ]
1689 Unloads media from drive <drivenum> into slot
1690 <slotnum>. If <drivenum> is omitted, defaults to
1691 drive 0 (as do all commands). If <slotnum> is
1692 omitted, defaults to the slot that the drive was
1693 loaded from. Note that there's currently no way
1694 to say 'unload drive 1's media to the slot it
1695 came from', other than to explicitly use that
1696 slot number as the destination.AB

1734 Handling removable disks
1736 From: Karl Cunningham <karlc@keckec.com>
1738 My backups are only to hard disk these days, in removable bays. This is my
1739 idea of how a backup to hard disk would work more smoothly. Some of these
1740 things Bacula does already, but I mention them for completeness. If others
1741 have better ways to do this, I'd like to hear about it.
1743 1. Accommodate several disks, rotated similar to how tapes are. Identified
1744 by partition volume ID or perhaps by the name of a subdirectory.
1745 2. Abort & notify the admin if the wrong disk is in the bay.
1746 3. Write backups to different subdirectories for each machine to be backed
1748 4. Volumes (files) get created as needed in the proper subdirectory, one
1750 5. When a disk is recycled, remove or zero all old backup files. This is
1751 important as the disk being recycled may be close to full. This may be
1752 better done manually since the backup files for many machines may be
1753 scattered in many subdirectories.
1758 - Why the heck doesn't bacula drop root priviledges before connecting to
1760 - Look at using posix_fadvise(2) for backups -- see bug #751.
1761 Possibly add the code at findlib/bfile.c:795
1762 /* TCP socket options */
1763 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1764 - Fix bnet_connect() code to set a timer and to use time to
1766 - Implement 4th argument to make_catalog_backup that passes hostname.
1767 - Test FIFO backup/restore -- make regression
1768 - Please mount volume "xxx" on Storage device ... should also list
1769 Pool and MediaType in case user needs to create a new volume.
1770 - On restore add Restore Client, Original Client.

1779 - Check if gnome-console works with TLS.
1780 - the director seg faulted when I omitted the pool directive from a
1781 job resource. I was experimenting and thought it redundant that I had
1782 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1783 apparently not. This happened when I removed the pool directive and
1784 started the director.
1785 - Add Where: client:/.... to restore job report.
1786 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1787 does the right thing.
1788 - FD-SD quick disconnect
1789 - Building the in memory restore tree is slow.
