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

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

491 the Volume data (with the exception of VolumeState).
492 - The btape fill command does not seem to use the Autochanger
493 - Make Windows installer default to system disk drive.
494 - Look at using ioctl(FIOBMAP, ...) on Linux, and

522 insert into LevelType (LevelType,LevelTypeLong) values
526 - Show files/second in client status output.
527 - Add a recursive mark command (rmark) to restore.
528 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
529 of the same level and does not permit multiple simultaneous
530 running of that Job (i.e. lets any previous invocation finish
531 before doing Interval testing).
532 - Look at simplifying File exclusions.
533 - New directive "Delete purged Volumes"
534 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and

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

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

794 Media Type Write = LTO2, LTO3
796 === From Carsten Menke <bootsy52@gmx.net>
798 Following is a list of what I think in the situations where I'm faced with,
799 could be a usefull enhancement to bacula, which I'm certain other users will
800 benefit from as well.
802 1. NextJob/NextJobs Directive within a Job Resource in the form of
803 NextJobs = job1,job2.
806 I currently solved the problem with running multiple jobs each after each
807 by setting the Max Wait Time for a job to 8 hours, and give
808 the jobs different Priorities. However, there scenarios where
809 1 Job is directly depending on another job, so if the former job fails,
810 the job after it needn't to be run
811 while maybe other jobs should run despite of that
814 A Backup Job and a Verify job, if the backup job fails there is no need to run
815 the verify job, as the backup job already failed. However, one may like
816 to backup the Catalog to disk despite of that the main backup job failed.
819 I see that this is related to the Event Handlers which are on the ToDo
820 list, also it is maybe a good idea to check for the return value and
821 execute different actions based on the return value
824 3. offline capability to bconsole
827 Currently I use a script which I execute within the last Job via the
828 RunAfterJob Directive, to release and eject the tape.
829 So I have to call bconsole "release=Storage-Name" and afterwards
830 mt -f /dev/nst0 eject to get the tape out.
832 If I have multiple Storage Devices, than these may not be /dev/nst0 and
833 I have to modify the script or call it with parameters etc.
834 This would actually not be needed, as everything is already defined
835 in bacula-sd.conf and if I can invoke bconsole with the
836 storage name via $1 in the script than I'm done and information is
839 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
843 For the reason mentioned in 3. to have the ability to call a
844 script with /scripts/foobar %s and in the script use $1
845 to pass the Storage Name to bconsole
847 5. Setting Volume State within a Job Resource
850 Instead of using "Maximum Volume Jobs" in the Pool Resource,
851 I would have the possibilty to define
852 in a Job Resource that after this certain job is run, the Volume State
853 should be set to "Volume State = Used", this give more flexibility (IMHO).
855 6. Localization of Bacula Messages
858 Unfortunatley many,many people I work with don't speak english very well.
859 So if at least the Reporting messages would be localized then they
860 would understand that they have to change the tape,etc. etc.
862 I volunteer to do the german translations, and if I can convince my wife also
863 french and Morre (western african language).
865 7. OK, this is evil, probably bound to security risks and maybe not possible
866 due to the design of bacula.
868 Implementation of Backtics ( `command` ) for shell comand execution to
869 the "Label Format" Directive.
873 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
874 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
875 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
876 the localized name for the day of the week appended to the
877 format string. Then I have the tape labeled automatically with weekday
878 name in the correct language.
880 - Yes, that is surely the case. I probably should turn those into Warning
881 errors. In addition, you just made me think that it might not be bad to
882 add an option to check the file size after backing up the file and
883 report if it changes. This would be done as an option because it would
886 Kern, good idea. If you do do that, mention in the output: file
887 shrunk, or file expanded, just to make it obvious to the user
888 (without having to the refer to file size), just how the file size
891 Would this option be for all file, or just one file? Or a fileset?
892 - Make output from status use html table tags for nicely
893 presenting in a browser.
894 - Can one write tapes faster with 8192 byte block sizes?
895 - Document security problems with the same password for everyone in
896 rpm and Win32 releases.
897 - Browse generations of files.
898 - I've seen an error when my catalog's File table fills up. I
899 then have to recreate the File table with a larger maximum row
900 size. Relevant information is at
901 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
902 "Installing and Configuring MySQL" chapter should talk a bit
903 about this potential problem, and recommend a solution.
904 - For Solaris must use POSIX awk.
905 - Want speed of writing to tape while despooling.
906 - Supported autochanger:
914 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
915 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
916 - Add regex from http://www.pcre.org to Bacula for Win32.
917 - Use only shell tools no make in CDROM package.
918 - Include within include does it work?
919 - Implement a Pool of type Cleaning?
920 - Implement VolReadTime and VolWriteTime in SD
921 - Modify Backing up Your Database to include a bootstrap file.
922 - Think about making certain database errors fatal.
923 - Look at correcting the time jump in the scheduler for daylight
924 savings time changes.
925 - Add a "real" timer to network connections.
926 - Promote to Full = Time period
927 - Check dates entered by user for correctness (month/day/... ranges)
928 - Compress restore Volume listing by date and first file.
929 - Look at patches/bacula_db.b2z postgresql that loops during restore.
931 - Perhaps add read/write programs and/or plugins to FileSets.
932 - How to handle backing up portables ...
933 - Add some sort of guaranteed Interval for upgrading jobs.
934 - Can we write the state file after every job terminates? On Win32
935 the system crashes and the state file is not updated.
938 Documentation to do: (any release a little bit at a time)
939 - Doc to do unmount before removing magazine.
940 - Alternative to static linking "ldd prog" save all binaries listed,
941 restore them and point LD_LIBRARY_PATH to them.
942 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
943 - Document query file format.
944 - Add more documentation for bsr files.
945 - Document problems with Verify and pruning.
946 - Document how to use multiple databases.
947 - VXA drives have a "cleaning required"
948 indicator, but Exabyte recommends preventive cleaning after every 75
951 In this context, it should be noted that Exabyte has a command-line
952 vxatool utility available for free download. (The current version is
953 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
954 test the drive, unload tapes, change drive settings, flash new firmware,
956 Of particular interest in this context is that vxatool <device> -i will
957 report, among other details, the time since last cleaning in tape motion
958 minutes. This information can be retrieved (and settings changed, for
959 that matter) through the generic-SCSI device even when Bacula has the
960 regular tape device locked. (Needless to say, I don't recommend
961 changing tape settings while a job is running.)
962 - Lookup HP cleaning recommendations.
963 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
964 - Document doing table repair
967 ===================================
968 - Add macro expansions in JobDefs.
969 Run Before Job = "SomeFile %{Level} %{Client}"
970 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
971 - Use non-blocking network I/O but if no data is available, use
973 - Use gather write() for network I/O.
974 - Autorestart on crash.
975 - Add bandwidth limiting.
976 - Add acks every once and a while from the SD to keep
977 the line from timing out.
978 - When an error in input occurs and conio beeps, you can back
979 up through the prompt.
980 - Detect fixed tape block mode during positioning by looking at
981 block numbers in btape "test". Possibly adjust in Bacula.
982 - Fix list volumes to output volume retention in some other
983 units, perhaps via a directive.
984 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
985 with multiple priorities.
986 - If you use restore replace=never, the directory attributes for
987 non-existent directories will not be restored properly.
989 - see lzma401.zip in others directory for new compression
991 - Allow the user to select JobType for manual pruning/purging.
992 - bscan does not put first of two volumes back with all info in
994 - Implement the FreeBSD nodump flag in chflags.
995 - Figure out how to make named console messages go only to that
996 console and to the non-restricted console (new console class?).
997 - Make restricted console prompt for password if *ask* is set or
998 perhaps if password is undefined.
999 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1002 ==== from Marc Schoechlin
1003 - the help-command should be more verbose
1004 (it should explain the paramters of the different
1006 -> its time-comsuming to consult the manual anytime
1007 you need a special parameter
1008 -> maybe its more easy to maintain this, if the
1009 descriptions of that commands are outsourced to
1011 - the cd-command should allow complete paths
1012 i.e. cd /foo/bar/foo/bar
1013 -> if a customer mails me the path to a certain file,
1014 its faster to enter the specified directory
1015 - if the password is not configured in bconsole.conf
1016 you should be asked for it.
1017 -> sometimes you like to do restore on a customer-machine
1018 which shouldnt know the password for bacula.
1019 -> adding the password to the file favours admins
1020 to forget to remove the password after usage
1022 the protection of that file is less important
1023 - long-listed-output of commands should be scrollable
1024 like the unix more/less-command does
1025 -> if someone runs 200 and more machines, the lists could
1026 be a little long and complex
1027 - command-output should be shown column by column
1028 to reduce scrolling and to increase clarity
1030 - lsmark should list the selected files with full
1032 - wildcards for selecting and file and directories would be nice
1033 - any actions should be interuptable with STRG+C
1034 - command-expansion would be pretty cool
1036 - When the replace Never option is set, new directory permissions
1037 are not restored. See bug 213. To fix this requires creating a
1038 list of newly restored directories so that those directory
1039 permissions *can* be restored.
1040 - Add prune all command
1041 - Document fact that purge can destroy a part of a restore by purging
1042 one volume while others remain valid -- perhaps mark Jobs.
1043 - Add multiple-media-types.txt
1044 - look at mxt-changer.html
1045 - Make ? do a help command (no return needed).
1046 - Implement restore directory.
1047 - Document streams and how to implement them.
1048 - Try not to re-backup a file if a new hard link is added.
1049 - Add feature to backup hard links only, but not the data.
1050 - Fix stream handling to be simpler.
1051 - Add Priority and Bootstrap to Run a Job.
1052 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1054 - Remove View FileSet button from Run a Job dialog.
1055 - Handle prompt for restore job at end of Restore command.
1056 - Add display of total selected files to Restore window.
1057 - Add tree pane to left of window.
1058 - Add progress meter.
1059 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1060 - Add message to user to check for fixed block size when the forward
1061 space test fails in btape.
1062 - When unmarking a directory check if all files below are unmarked and
1063 then remove the + flag -- in the restore tree.
1064 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1065 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1066 - Revisit the question of multiple Volumes (disk) on a single device.
1067 - Add a block copy option to bcopy.
1068 - Finish work on Gnome restore GUI.
1069 - Fix "llist jobid=xx" where no fileset or client exists.
1070 - For each job type (Admin, Restore, ...) require only the really necessary
1071 fields.- Pass Director resource name as an option to the Console.
1072 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1073 - Add a .list all files in the restore tree (probably also a list all files)
1074 Do both a long and short form.
1075 - Allow browsing the catalog to see all versions of a file (with
1076 stat data on each file).
1077 - Restore attributes of directory if replace=never set but directory
1079 - Use SHA1 on authentication if possible.
1080 - See comtest-xxx.zip for Windows code to talk to USB.
1081 - Add John's appended files:
1082 Appended = { /files/server/logs/http/*log }
1083 and such files would be treated as follows.On a FULL backup, they would
1084 be backed up like any other file.On an INCREMENTAL backup, where a
1085 previous INCREMENTAL or FULL was already in thecatalogue and the length
1086 of the file wasgreater than the length of the last backup, only thedata
1087 added since the last backup will be dumped.On an INCREMENTAL backup, if
1088 the length of the file is less than thelength of the file with the same
1089 name last backed up, the completefile is dumped.On Windows systems, with
1090 creation date of files, we can be evensmarter about this and not count
1091 entirely upon the length.On a restore, the full and all incrementals
1092 since it will beapplied in sequence to restore the file.
1093 - Check new HAVE_WIN32 open bits.
1094 - Check if the tape has moved before writing.
1095 - Handling removable disks -- see below:
1096 - Keep track of tape use time, and report when cleaning is necessary.
1097 - Add FromClient and ToClient keywords on restore command (or
1098 BackupClient RestoreClient).
1099 - Implement a JobSet, which groups any number of jobs. If the
1100 JobSet is started, all the jobs are started together.
1101 Allow Pool, Level, and Schedule overrides.
1102 - Enhance cancel to timeout BSOCK packets after a specific delay.
1103 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1104 ua_status.!!! Thanks to Alan Brown for this tip.
1105 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1106 correctly for multiple simultaneous jobs.
1107 - Correct code so that FileSet MD5 is calculated for < and | filename
1109 - Implement the Media record flag that indicates that the Volume does disk
1111 - Implement VolAddr, which is used when Volume is addressed like a disk,
1112 and form it from VolFile and VolBlock.
1113 - Make multiple restore jobs for multiple media types specifying
1114 the proper storage type.
1115 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1116 pointer (rec) to try_repositioning().
1117 - Look at extracting Win data from BackupRead.
1118 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1119 which would take precidence over the Catalog "JobRetention".
1120 - Implement Label Format in Add and Label console commands.
1121 - Possibly up network buffers to 65K. Put on variable.
1122 - Put email tape request delays on one or more variables. User wants
1123 to cancel the job after a certain time interval. Maximum Mount Wait?
1124 - Job, Client, Device, Pool, or Volume?
1125 Is it possible to make this a directive which is *optional* in multiple
1126 resources, like Level? If so, I think I'd make it an optional directive
1127 in Job, Client, and Pool, with precedence such that Job overrides Client
1128 which in turn overrides Pool.
1130 - New Storage specifications:
1131 - Want to write to multiple storage devices simultaneously
1132 - Want to write to multiple storage devices sequentially (in one job)
1133 - Want to read/write simultaneously
1134 - Key is MediaType -- it must match
1136 Passed to SD as a sort of BSR record called Storage Specification
1140 MediaType -> Next MediaType
1142 Device -> Next Device
1144 Allow multiple Storage specifications
1152 Allow Multiple Pool specifications (note, Pool currently
1154 Allow Multiple MediaType specifications in Dir conf
1155 Allow Multiple Device specifications in Dir conf
1156 Perhaps keep this in a single SSR
1157 Tie a Volume to a specific device by using a MediaType that
1158 is contained in only one device.
1159 In SD allow Device to have Multiple MediaTypes
1161 - Ideas from Jerry Scharf:
1162 First let's point out some big pluses that bacula has for this
1164 more importantly it's active. Thank you so much for that
1165 even more important, it's not flaky
1166 it has an open access catalog, opening many possibilities
1167 it's pushing toward heterogeneous systems capability

1182 support for Oracle database ??
1184 - Look at adding SQL server and Exchange support for Windows.
1185 - Make dev->file and dev->block_num signed integers so that -1 can
1186 be an invalid value which happens with BSR.
1187 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1188 is needed to properly specify ranges.
1189 - Add progress of files/bytes to SD and FD.
1190 - Print warning message if FileId > 4 billion
1191 - do a "messages" before the first prompt in Console
1192 - Client does not show busy during Estimate command.
1193 - Implement Console mtx commands.
1194 - Implement a Mount Command and an Unmount Command where
1195 the users could specify a system command to be performed
1196 to do the mount, after which Bacula could attempt to
1197 read the device. This is for Removeable media such as a CDROM.
1198 - Most likely, this mount command would be invoked explicitly
1199 by the user using the current Console "mount" and "unmount"
1200 commands -- the Storage Daemon would do the right thing
1201 depending on the exact nature of the device.
1202 - As with tape drives, when Bacula wanted a new removable
1203 disk mounted, it would unmount the old one, and send a message
1204 to the user, who would then use "mount" as described above
1205 once he had actually inserted the disk.
1206 - Implement dump/print label to UA
1207 - Spool to disk only when the tape is full, then when a tape is hung move
1209 - bextract is sending everything to the log file ****FIXME****
1210 - Allow multiple Storage specifications (or multiple names on
1211 a single Storage specification) in the Job record. Thus a job
1212 can be backed up to a number of storage devices.
1213 - Implement some way for the File daemon to contact the Director
1214 to start a job or pass its DHCP obtained IP number.
1215 - Implement a query tape prompt/replace feature for a console
1216 - Copy console @ code to gnome2-console
1217 - Make tree walk routines like cd, ls, ... more user friendly
1218 by handling spaces better.
1219 - Make sure that Bacula rechecks the tape after the 20 min wait.
1220 - Set IO_NOWAIT on Bacula TCP/IP packets.
1221 - Try doing a raw partition backup and restore by mounting a
1223 - From Lars Kellers:
1224 Yes, it would allow to highly automatic the request for new tapes. If a
1225 tape is empty, bacula reads the barcodes (native or simulated), and if
1226 an unused tape is found, it runs the label command with all the
1227 necessary parameters.
1229 By the way can bacula automatically "move" an empty/purged volume say
1230 in the "short" pool to the "long" pool if this pool runs out of volume
1232 - What to do about "list files job=xxx".
1233 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1234 file descriptor leak in Bacula.
1235 - Implement WrapCounters in Counters.
1236 - Add heartbeat from FD to SD if hb interval expires.
1237 - Can we dynamically change FileSets?
1238 - If pool specified to label command and Label Format is specified,
1239 automatically generate the Volume name.
1240 - Why can't SQL do the filename sort for restore?
1241 - Add ExhautiveRestoreSearch
1242 - Look at the possibility of loading only the necessary
1243 data into the restore tree (i.e. do it one directory at a
1244 time as the user walks through the tree).
1245 - Possibly use the hash code if the user selects all for a restore command.
1246 - Fix "restore all" to bypass building the tree.
1247 - Prohibit backing up archive device (findlib/find_one.c:128)
1248 - Implement Release Device in the Job resource to unmount a drive.
1249 - Implement Acquire Device in the Job resource to mount a drive,
1250 be sure this works with admin jobs so that the user can get
1251 prompted to insert the correct tape. Possibly some way to say to
1252 run the job but don't save the files.
1253 - Make things like list where a file is saved case independent for
1255 - Use autochanger to handle multiple devices.
1256 - Implement a Recycle command
1257 - Start working on Base jobs.
1258 - Implement UnsavedFiles DB record.
1259 - From Phil Stracchino:
1260 It would probably be a per-client option, and would be called
1261 something like, say, "Automatically purge obsoleted jobs". What it
1262 would do is, when you successfully complete a Differential backup of a
1263 client, it would automatically purge all Incremental backups for that
1264 client that are rendered redundant by that Differential. Likewise,
1265 when a Full backup on a client completed, it would automatically purge
1266 all Differential and Incremental jobs obsoleted by that Full backup.
1267 This would let people minimize the number of tapes they're keeping on
1268 hand without having to master the art of retention times.
1269 - When doing a Backup send all attributes back to the Director, who
1270 would then figure out what files have been deleted.
1271 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1272 explicit permission to do so. It should also mark the tape in error
1273 if there is an error.
1274 - Cancel waiting for Client connect in SD if FD goes away.
1276 - Implement timeout in response() when it should come quickly.
1277 - Implement a Slot priority (loaded/not loaded).
1278 - Implement "vacation" Incremental only saves.
1279 - Implement create "FileSet"?
1280 - Add prefixlinks to where or not where absolute links to FD.
1281 - Issue message to mount a new tape before the rewind.
1282 - Simplified client job initiation for portables.
1283 - If SD cannot open a drive, make it periodically retry.
1284 - Add more of the config info to the tape label.
1286 - Refine SD waiting output:
1287 Device is being positioned
1288 > Device is being positioned for append
1289 > Device is being positioned to file x
1291 - Figure out some way to estimate output size and to avoid splitting
1292 a backup across two Volumes -- this could be useful for writing CDROMs
1293 where you really prefer not to have it split -- not serious.
1294 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1295 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1296 actual data on the Volume and compare it.
1297 - Implement Bacula plugins -- design API
1298 - Make bcopy read through bad tape records.
1299 - Program files (i.e. execute a program to read/write files).
1300 Pass read date of last backup, size of file last time.
1301 - Add Signature type to File DB record.
1302 - CD into subdirectory when open()ing files for backup to
1303 speed up things. Test with testfind().
1304 - Priority job to go to top of list.
1305 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1306 - Implement some way for the Console to dynamically create a job.
1307 - Solaris -I on tar for include list
1308 - Need a verbose mode in restore, perhaps to bsr.
1309 - bscan without -v is too quiet -- perhaps show jobs.
1310 - Add code to reject whole blocks if not wanted on restore.
1311 - Check if we can increase Bacula FD priorty in Win2000
1312 - Make sure the MaxVolFiles is fully implemented in SD
1313 - Check if both CatalogFiles and UseCatalog are set to SD.
1314 - Possibly add email to Watchdog if drive is unmounted too
1315 long and a job is waiting on the drive.
1316 - After unmount, if restore job started, ask to mount.
1317 - Add UA rc and history files.
1318 - put termcap (used by console) in ./configure and
1319 allow -with-termcap-dir.
1320 - Fix Autoprune for Volumes to respect need for full save.
1321 - Compare tape to Client files (attributes, or attributes and data)
1322 - Make all database Ids 64 bit.
1323 - Allow console commands to detach or run in background.
1324 - Add SD message variables to control operator wait time
1325 - Maximum Operator Wait
1326 - Minimum Message Interval
1327 - Maximum Message Interval
1328 - Send Operator message when cannot read tape label.
1329 - Verify level=Volume (scan only), level=Data (compare of data to file).
1330 Verify level=Catalog, level=InitCatalog
1332 - Add keyword search to show command in Console.
1333 - Events : tape has more than xxx bytes.
1334 - Complete code in Bacula Resources -- this will permit
1335 reading a new config file at any time.
1336 - Handle ctl-c in Console
1337 - Implement script driven addition of File daemon to config files.
1338 - Think about how to make Bacula work better with File (non-tape) archives.
1339 - Write Unix emulator for Windows.
1340 - Put memory utilization in Status output of each daemon
1341 if full status requested or if some level of debug on.
1342 - Make database type selectable by .conf files i.e. at runtime
1343 - Set flag for uname -a. Add to Volume label.
1344 - Restore files modified after date
1345 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1346 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1347 - Timout a job or terminate if link goes down, or reopen link and query.
1348 - Concept of precious tapes (cannot be reused).
1349 - Make bcopy copy with a single tape drive.
1350 - Permit changing ownership during restore.

1364 - Autolabel should be specified by DIR instead of SD.
1366 - Add media capacity
1367 - AutoScan (check checksum of tape)
1368 - Format command = "format /dev/nst0"
1372 - Seek resolution (usually corresponds to buffer size)
1373 - EODErrorCode=ENOSPC or code
1374 - Partial Read error code
1375 - Partial write error code
1376 - Nonformatted read error
1377 - Nonformatted write error

1409 - Director needs a time after which the report status is sent
1410 anyway -- or better yet, a retry time for the job.
1411 - Don't reschedule a job if previous incarnation is still running.
1412 - Some way to automatically backup everything is needed????

1419 owner, group, user, quotas
1420 - Store info on each file system type (probably in the job header on tape.
1421 This could be the output of df; or perhaps some sort of /etc/mtab record.
1423 ========= ideas ===============
1424 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1425 To: <kern@sibbald.com>
1426 Subject: RE: [Bacula-users] future large programming jobs
1427 Date: Thu, 26 Feb 2004 11:34:54 -0600
1429 I noticed the subject thread and thought I would offer the following
1430 merely as sources of ideas, i.e. something to think about, not even as
1431 strong as a request. In my former life (before retiring) I often
1432 dealt with backups and storage management issues/products as a
1433 developer and as a consultant. I am currently migrating my personal
1434 network from amanda to bacula specifically because of the ability to
1435 cross media boundaries during storing backups.
1436 Are you familiar with the commercial product called ADSM (I think IBM
1437 now sells it under the Tivoli label)? It has a couple of interesting
1438 ideas that may apply to the following topics.
1440 1. Migration: Consider that when you need to restore a system, there
1441 may be pressure to hurry. If all the information for a single client
1442 can eventually end up on the same media (and in chronological order),
1443 the restore is facillitated by not having to search past information
1444 from other clients. ADSM has the concept of "client affinity" that
1445 may be associated with it's storage pools. It seems to me that this
1446 concept (as an optional feature) might fit in your architecture for
1449 ADSM also has the concept of defining one or more storage pools as
1450 "copy pools" (almost mirrors, but only in the sense of contents).
1451 These pools provide the ability to have duplicte data stored both
1452 onsite and offsite. The copy process can be scheduled to be handled
1453 by their storage manager during periods when there is no backup
1454 activity. Again, the migration process might be a place to consider
1455 implementing something like this.
1458 > It strikes me that it would be very nice to be able to do things
1460 > have the Job(s) backing up the machines run, and once they have all

1466 > mechanism described below would probably make it very easy.
1468 This is the goal. In the first step (before events), you simply
1470 the Migration to tape later.
1472 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1473 the database. Once a file (unique by path and metadata such as dates,
1474 size, ownership, etc.) is in a copy pool, no more copies are made. In
1475 other words, when you start ADSM, it begins like your concept of a
1476 base job. After that it is in the "incremental" mode. You can
1477 configure the number of "generations" of files to be retained, plus a
1478 retention date after which even old generations are purged. The
1479 database tracks the contents of media and projects the percentage of
1480 each volume that is valid. When the valid content of a volume drops
1481 below a configured percentage, the valid data are migrated to another
1482 volume and the old volume is marked as empty. Note, this requires
1483 ADSM to have an idea of the contents of a client, i.e. marking the
1484 database when an existing file was deleted, but this would solve your
1485 issue of restoring a client without restoring deleted files.
1487 This is pretty far from what bacula now does, but if you are going to
1488 rip things up for Base jobs,.....
1489 Also, the benefits of this are huge for very large shops, especially
1490 with media robots, but are a pain for shops with manual media
1494 > Base jobs sound pretty useful, but I'm not dying for them.
1496 Nobody is dying for them, but when you see what it does, you will die
1499 3. Restoring deleted files: Since I think my comments in (2) above
1500 have low probability of implementation, I'll also suggest that you
1501 could approach the issue of deleted files by a mechanism of having the
1502 fd report to the dir, a list of all files on the client for every
1503 backup job. The dir could note in the database entry for each file
1504 the date that the file was seen. Then if a restore as of date X takes
1505 place, only files that exist from before X until after X would be
1506 restored. Probably the major cost here is the extra date container in
1507 each row of the files table.
1509 Thanks for "listening". I hope some of this helps. If you want to
1510 contact me, please send me an email - I read some but not all of the
1511 mailing list traffic and might miss a reply there.
1513 Please accept my compliments for bacula. It is doing a great job for
1514 me!! I sympathize with you in the need to wrestle with excelence in
1515 execution vs. excelence in feature inclusion.
1520 ==============================
1523 - Design at hierarchial storage for Bacula. Migration and Clone.
1524 - Implement FSM (File System Modules).
1525 - Audit M_ error codes to ensure they are correct and consistent.
1526 - Add variable break characters to lex analyzer.
1527 Either a bit mask or a string of chars so that
1528 the caller can change the break characters.
1529 - Make a single T_BREAK to replace T_COMMA, etc.
1530 - Ensure that File daemon and Storage daemon can
1531 continue a save if the Director goes down (this
1532 is NOT currently the case). Must detect socket error,
1533 buffer messages for later.
1534 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1535 - Add ability to backup to two Storage devices (two SD sessions) at
1536 the same time -- e.g. onsite, offsite.
1537 - Add the ability to consolidate old backup sets (basically do a restore
1538 to tape and appropriately update the catalog). Compress Volume sets.
1539 Might need to spool via file is only one drive is available.
1540 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1541 someway to do so with every volume that has less than x% valid
1545 Migration: Move a backup from one Volume to another
1546 Clone: Copy a backup -- two Volumes
1549 ======================================================
1551 It is somewhat like a Full save becomes an incremental since
1552 the Base job (or jobs) plus other non-base files.
1554 - A Base backup is same as Full backup, just different type.
1555 - New BaseFiles table that contains:
1557 BaseJobId - Base JobId referenced for this FileId (needed ???)
1558 JobId - JobId currently running
1559 FileId - File not backed up, exists in Base Job
1560 FileIndex - FileIndex from Base Job.
1561 i.e. for each base file that exists but is not saved because
1562 it has not changed, the File daemon sends the JobId, BaseId,
1563 FileId, FileIndex back to the Director who creates the DB entry.
1564 - To initiate a Base save, the Director sends the FD
1565 the FileId, and full filename for each file in the Base.
1566 - When the FD finds a Base file, he requests the Director to
1567 send him the full File entry (stat packet plus MD5), or
1568 conversely, the FD sends it to the Director and the Director
1569 says yes or no. This can be quite rapid if the FileId is kept
1570 by the FD for each Base Filename.
1571 - It is probably better to have the comparison done by the FD
1572 despite the fact that the File entry must be sent across the
1574 - An alternative would be to send the FD the whole File entry
1575 from the start. The disadvantage is that it requires a lot of
1576 space. The advantage is that it requires less communications
1578 - The Job record must be updated to indicate that one or more
1580 - At end of Job, FD returns:
1581 1. Count of base files/bytes not written to tape (i.e. matches)
1582 2. Count of base file that were saved i.e. had changed.
1583 - No tape record would be written for a Base file that matches, in the
1584 same way that no tape record is written for Incremental jobs where
1585 the file is not saved because it is unchanged.
1586 - On a restore, all the Base file records must explicitly be
1587 found from the BaseFile tape. I.e. for each Full save that is marked
1588 to have one or more Base Jobs, search the BaseFile for all occurrences
1590 - An optimization might be to make the BaseFile have:
1596 This would avoid the need to explicitly fetch each File record for
1597 the Base job. The Base Job record will be fetched to get the
1598 VolSessionId and VolSessionTime.
1599 =========================================================
1602 ==========================================================
1604 For each Incremental job that is run, there may be files that
1605 were found but not saved because they were locked (this applies
1606 only to Windows). Such a system could send back to the Director
1607 a list of Unsaved files.
1609 - New UnSavedFiles table that contains:
1613 - Then in the next Incremental job, the list of Unsaved Files will be
1614 feed to the FD, who will ensure that they are explicitly chosen even
1615 if standard date/time check would not have selected them.

1660 There needs to be a table of drive # to devices somewhere - If there are
1661 multiple changers or drives there may not be a 1:1 correspondance between
1662 changer drive number and system device name - and depending on the way the
1663 drives are hooked up to scsi busses, they may not be linearly numbered
1664 from an offset point either.something like
1666 Autochanger drives = 2
1667 Autochanger drive 0 = /dev/nst1
1668 Autochanger drive 1 = /dev/nst2
1669 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1670 times, not just for multidrive changers. For a 1 drive changer, that's
1676 MTX's manpage (1.2.15):
1677 unload [<slotnum>] [ <drivenum> ]
1678 Unloads media from drive <drivenum> into slot
1679 <slotnum>. If <drivenum> is omitted, defaults to
1680 drive 0 (as do all commands). If <slotnum> is
1681 omitted, defaults to the slot that the drive was
1682 loaded from. Note that there's currently no way
1683 to say 'unload drive 1's media to the slot it
1684 came from', other than to explicitly use that
1685 slot number as the destination.AB

1723 Handling removable disks
1725 From: Karl Cunningham <karlc@keckec.com>
1727 My backups are only to hard disk these days, in removable bays. This is my
1728 idea of how a backup to hard disk would work more smoothly. Some of these
1729 things Bacula does already, but I mention them for completeness. If others
1730 have better ways to do this, I'd like to hear about it.
1732 1. Accommodate several disks, rotated similar to how tapes are. Identified
1733 by partition volume ID or perhaps by the name of a subdirectory.
1734 2. Abort & notify the admin if the wrong disk is in the bay.
1735 3. Write backups to different subdirectories for each machine to be backed
1737 4. Volumes (files) get created as needed in the proper subdirectory, one
1739 5. When a disk is recycled, remove or zero all old backup files. This is
1740 important as the disk being recycled may be close to full. This may be
1741 better done manually since the backup files for many machines may be
1742 scattered in many subdirectories.
1747 - Why the heck doesn't bacula drop root priviledges before connecting to
1749 - Look at using posix_fadvise(2) for backups -- see bug #751.
1750 Possibly add the code at findlib/bfile.c:795
1751 /* TCP socket options */
1752 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1753 - Fix bnet_connect() code to set a timer and to use time to
1755 - Implement 4th argument to make_catalog_backup that passes hostname.
1756 - Test FIFO backup/restore -- make regression
1757 - Please mount volume "xxx" on Storage device ... should also list
1758 Pool and MediaType in case user needs to create a new volume.
1759 - On restore add Restore Client, Original Client.

1768 - Check if gnome-console works with TLS.
1769 - the director seg faulted when I omitted the pool directive from a
1770 job resource. I was experimenting and thought it redundant that I had
1771 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1772 apparently not. This happened when I removed the pool directive and
1773 started the director.
1774 - Add Where: client:/.... to restore job report.
1775 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1776 does the right thing.
1777 - FD-SD quick disconnect
1778 - Building the in memory restore tree is slow.
