16 if the system "sees" a long path once, it seems to forget it's
17 working drive (e.g. c:\), which will lead to a problem during

104 - Given all the problems with FIFOs, I think the solution is to do something a
105 little different, though I will look at the code and see if there is not some
106 simple solution (i.e. some bug that was introduced). What might be a better
107 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
108 write data to a program rather than the FIFO. For example, suppose you
113 Then, I could imagine if you backup and restore this file with a direct
114 reference as is currently done for fifos, instead, during backup Bacula will
117 /home/kern/my-fifo.backup
119 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
122 /home/kern/my-fifo.restore
124 and send the data backed up to stdout. These programs can either be an
125 executable or a shell script and they need only read/write to stdin/stdout.
127 I think this would give a lot of flexibility to the user without making any
128 significant changes to Bacula.

145 === Migration from David ===
146 What I'd like to see:
149 Name = "<poolname>-migrate"
153 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
154 Client | PoolResidence | Volume | JobName | SQLquery
155 Migration Selection Pattern = "regexp"
156 Next Pool = <override>
159 There should be no need for a Level (migration is always Full, since you
160 don't calculate differential/incremental differences for migration),
161 Storage should be determined by the volume types in the pool, and Client
162 is really a selection issue. Migration should always occur to the
163 NextPool defined in the pool definition. If no nextpool is defined, the
164 job should end with a reason of "no place to go". If Next Pool statement
165 is present, we override the check in the pool definition and use the
168 Here's how I'd define Migration Selection Types:
171 Client -- Migrate data from selected client only. Migration Selection
172 Pattern regexp provides pattern to select client names, eg ^FS00* makes
173 all client names starting with FS00 eligible for migration.
175 Jobname -- Migration all jobs matching name. Migration Selection Pattern
176 regexp provides pattern to select jobnames existing in pool.
178 Volume -- Migrate all data on specified volumes. Migration Selection
179 Pattern regexp provides selection criteria for volumes to be migrated.
180 Volumes must exist in pool to be eligible for migration.
184 LowestUtil -- Identify the volume in the pool with the least data on it
185 and empty it. No Migration Selection Pattern required.
187 OldestVol -- Identify the LRU volume with data written, and empty it. No
188 Migration Selection Pattern required.
190 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
191 (starting with most full volumes) until pool occupancy drops below
192 <lowmig>. Pool highmig and lowmig values are in pool definition, no
193 Migration Selection Pattern required.
197 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
198 Migration Selection Pattern contains SQL query to execute; should return
199 a list of 1 or more jobuids to migrate.
201 PoolResidence -- Migrate data sitting in pool for longer than
202 PoolResidence value in pool definition. Migration Selection Pattern
203 optional; if specified, override value in pool definition (value in

321 the Volume data (with the exception of VolumeState).
322 - The btape fill command does not seem to use the Autochanger
323 - Make Windows installer default to system disk drive.

345 hidden in the file listing ...
346 - Look at -D_FORTIFY_SOURCE=2
347 - Add Win32 FileSet definition somewhere

389 1. When jobs are running and bacula for some reason crashes or if I do a
390 restart it remembers and jobs it was running before it crashed or restarted
391 as of now I loose all jobs if I restart it.
393 2. When spooling and in the midway if client is disconnected for instance a
394 laptop bacula completely discard the spool. It will be nice if it can write
395 that spool to tape so there will be some backups for that client if not all.
397 3. We have around 150 clients machines it will be nice to have a option to
398 upgrade all the client machines bacula version automatically.
400 4. Atleast one connection should be reserved for the bconsole so at heavy load
401 I should connect to the director via bconsole which at sometimes I can't
403 5. Another most important feature that is missing, say at 10am I manually
404 started backup of client abc and it was a full backup since client abc has
405 no backup history and at 10.30am bacula again automatically started backup of
406 client abc as that was in the schedule. So now we have 2 multiple Full
407 backups of the same client and if we again try to start a full backup of
408 client backup abc bacula won't complain. That should be fixed.
410 - Fix bpipe.c so that it does not modify results pointer.
411 ***FIXME*** calling sequence should be changed.
412 - For Windows disaster recovery see http://unattended.sf.net/
413 - regardless of the retention period, Bacula will not prune the
414 last Full, Diff, or Inc File data until a month after the
415 retention period for the last Full backup that was done.
416 - update volume=xxx --- add status=Full
417 - Remove old spool files on startup.
418 - Exclude SD spool/working directory.
419 - Refuse to prune last valid Full backup. Same goes for Catalog.
421 - Make a callback when Rerun failed levels is called.
422 - Give Python program access to Scheduled jobs.
423 - Add setting Volume State via Python.
424 - Python script to save with Python, not save, save with Bacula.
425 - Python script to do backup.
427 - Change the Priority, Client, Storage, JobStatus (error)
428 at the start of a job.
429 - Why is SpoolDirectory = /home/bacula/spool; not reported
430 as an error when writing a DVD?
431 - Make bootstrap file handle multiple MediaTypes (SD)
432 - Remove all old Device resource code in Dir and code to pass it
433 back in SD -- better, rework it to pass back device statistics.
434 - Check locking of resources -- be sure to lock devices where previously
435 resources were locked.
436 - The last part is left in the spool dir.
439 - In restore don't compare byte count on a raw device -- directory
440 entry does not contain bytes.
441 - To mark files as deleted, run essentially a Verify to disk, and
442 when a file is found missing (MarkId != JobId), then create
443 a new File record with FileIndex == -1. This could be done
444 by the FD at the same time as the backup.
448 MA = (last_MA * 3 + rate) / 4
449 rate = (bytes - last_bytes) / (runtime - last_runtime)
450 - Max Vols limit in Pool off by one?
451 - Implement Files/Bytes,... stats for restore job.
452 - Implement Total Bytes Written, ... for restore job.
453 - Despool attributes simultaneously with data in a separate
454 thread, rejoined at end of data spooling.
455 - 7. Implement new Console commands to allow offlining/reserving drives,
456 and possibly manipulating the autochanger (much asked for).
457 - Add start/end date editing in messages (%t %T, %e?) ...
458 - Add ClientDefs similar to JobDefs.
459 - Print more info when bextract -p accepts a bad block.
460 - Fix FD JobType to be set before RunBeforeJob in FD.
461 - Look at adding full Volume and Pool information to a Volume
462 label so that bscan can get *all* the info.
463 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
464 and there is only one volume in the pool, refuse to do it -- otherwise
465 he fills the Volume, then immediately starts reusing it.
466 - Implement copies and stripes.
467 - Add history file to console.
468 - Each file on tape creates a JobMedia record. Peter has 4 million
469 files spread over 10000 tape files and four tapes. A restore takes
470 16 hours to build the restore list.
471 - Add and option to check if the file size changed during backup.
472 - Make sure SD deletes spool files on error exit.
473 - Delete old spool files when SD starts.
474 - When labeling tapes, if you enter 000026, Bacula uses
475 the tape index rather than the Volume name 000026.
476 - Add offline tape command to Bacula console.
478 Enter MediaId or Volume name: 32
479 Enter new Volume name: DLT-20Dec04

488 Label command failed for Volume DLT-20Dec04.
489 Do not forget to mount the drive!!!
490 - Bug: if a job is manually scheduled to run later, it does not appear
491 in any status report and cannot be cancelled.
493 ==== Keeping track of deleted files ====
494 My "trick" for keeping track of deletions is the following.
495 Assuming the user turns on this option, after all the files
496 have been backed up, but before the job has terminated, the
497 FD will make a pass through all the files and send their
498 names to the DIR (*exactly* the same as what a Verify job
499 currently does). This will probably be done at the same
500 time the files are being sent to the SD avoiding a second
501 pass. The DIR will then compare that to what is stored in
502 the catalog. Any files in the catalog but not in what the
503 FD sent will receive a catalog File entry that indicates
504 that at that point in time the file was deleted.
506 During a restore, any file initially picked up by some
507 backup (Full, ...) then subsequently having a File entry
508 marked "delete" will be removed from the tree, so will not
509 be restored. If a file with the same name is later OK it
510 will be inserted in the tree -- this already happens. All
511 will be consistent except for possible changes during the
514 Since I'm on the subject, some of you may be wondering what
515 the utility of the in memory tree is if you are going to
516 restore everything (at least it comes up from time to time
517 on the list). Well, it is still *very* useful because it
518 allows only the last item found for a particular filename
519 (full path) to be entered into the tree, and thus if a file
520 is backed up 10 times, only the last copy will be restored.
521 I recently (last Friday) restored a complete directory, and
522 the Full and all the Differential and Incremental backups
523 spanned 3 Volumes. The first Volume was not even mounted
524 because all the files had been updated and hence backed up
525 since the Full backup was made. In this case, the tree
526 saved me a *lot* of time.
528 Make sure this information is stored on the tape too so
529 that it can be restored directly from the tape.
531 Comments from Martin Simmons (I think they are all covered):
532 Ok, that should cover the basics. There are few issues though:
534 - Restore will depend on the catalog. I think it is better to include the
535 extra data in the backup as well, so it can be seen by bscan and bextract.
537 - I'm not sure if it will preserve multiple hard links to the same inode. Or
538 maybe adding or removing links will cause the data to be dumped again?
540 - I'm not sure if it will handle renamed directories. Possibly it will work
541 by dumping the whole tree under a renamed directory?
543 - It remains to be seen how the backup performance of the DIR's will be
544 affected when comparing the catalog for a large filesystem.
548 How about introducing a Type = MgmtPolicy job type? That job type would
549 be responsible for scanning the Bacula environment looking for specific
550 conditions, and submitting the appropriate jobs for implementing said
554 Name = "Migration-Policy"
556 Policy Selection Job Type = Migrate
557 Scope = "<keyword> <operator> <regexp>"
558 Threshold = "<keyword> <operator> <regexp>"
559 Job Template = <template-name>
562 Where <keyword> is any legal job keyword, <operator> is a comparison
563 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
564 appropriate regexp. I could see an argument for Scope and Threshold
565 being SQL queries if we want to support full flexibility. The
566 Migration-Policy job would then get scheduled as frequently as a site
567 felt necessary (suggested default: every 15 minutes).
572 Name = "Migration-Policy"
574 Policy Selection Job Type = Migration
576 Threshold = "Migration Selection Type = LowestUtil"
577 Job Template = "MigrationTemplate"
580 would select all pools for examination and generate a job based on
581 MigrationTemplate to automatically select the volume with the lowest
582 usage and migrate it's contents to the nextpool defined for that pool.
584 This policy abstraction would be really handy for adjusting the behavior
585 of Bacula according to site-selectable criteria (one thing that pops
586 into mind is Amanda's ability to automatically adjust backup levels
587 depending on various criteria).
593 - Add Pool/Storage override regression test.

623 could be a usefull enhancement to bacula, which I'm certain other users will
624 benefit from as well.
626 1. NextJob/NextJobs Directive within a Job Resource in the form of
627 NextJobs = job1,job2.
630 I currently solved the problem with running multiple jobs each after each
631 by setting the Max Wait Time for a job to 8 hours, and give
632 the jobs different Priorities. However, there scenarios where
633 1 Job is directly depending on another job, so if the former job fails,
634 the job after it needn't to be run
635 while maybe other jobs should run despite of that
638 A Backup Job and a Verify job, if the backup job fails there is no need to run
639 the verify job, as the backup job already failed. However, one may like
640 to backup the Catalog to disk despite of that the main backup job failed.
643 I see that this is related to the Event Handlers which are on the ToDo
644 list, also it is maybe a good idea to check for the return value and
645 execute different actions based on the return value
648 3. offline capability to bconsole
651 Currently I use a script which I execute within the last Job via the
652 RunAfterJob Directive, to release and eject the tape.
653 So I have to call bconsole "release=Storage-Name" and afterwards
654 mt -f /dev/nst0 eject to get the tape out.
656 If I have multiple Storage Devices, than these may not be /dev/nst0 and
657 I have to modify the script or call it with parameters etc.
658 This would actually not be needed, as everything is already defined
659 in bacula-sd.conf and if I can invoke bconsole with the
660 storage name via $1 in the script than I'm done and information is
663 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
667 For the reason mentioned in 3. to have the ability to call a
668 script with /scripts/foobar %s and in the script use $1
669 to pass the Storage Name to bconsole
671 5. Setting Volume State within a Job Resource
674 Instead of using "Maximum Volume Jobs" in the Pool Resource,
675 I would have the possibilty to define
676 in a Job Resource that after this certain job is run, the Volume State
677 should be set to "Volume State = Used", this give more flexibility (IMHO).
679 6. Localization of Bacula Messages
682 Unfortunatley many,many people I work with don't speak english very well.
683 So if at least the Reporting messages would be localized then they
684 would understand that they have to change the tape,etc. etc.
686 I volunteer to do the german translations, and if I can convince my wife also
687 french and Morre (western african language).
689 7. OK, this is evil, probably bound to security risks and maybe not possible
690 due to the design of bacula.
692 Implementation of Backtics ( `command` ) for shell comand execution to
693 the "Label Format" Directive.
697 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
698 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
699 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
700 the localized name for the day of the week appended to the
701 format string. Then I have the tape labeled automatically with weekday
702 name in the correct language.
704 - Yes, that is surely the case. I probably should turn those into Warning
705 errors. In addition, you just made me think that it might not be bad to
706 add an option to check the file size after backing up the file and
707 report if it changes. This would be done as an option because it would
710 Kern, good idea. If you do do that, mention in the output: file
711 shrunk, or file expanded, just to make it obvious to the user
712 (without having to the refer to file size), just how the file size
715 Would this option be for all file, or just one file? Or a fileset?
716 - Make output from status use html table tags for nicely
717 presenting in a browser.
718 - Can one write tapes faster with 8192 byte block sizes?
719 - Document security problems with the same password for everyone in
720 rpm and Win32 releases.
721 - Browse generations of files.
722 - I've seen an error when my catalog's File table fills up. I
723 then have to recreate the File table with a larger maximum row
724 size. Relevant information is at
725 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
726 "Installing and Configuring MySQL" chapter should talk a bit
727 about this potential problem, and recommend a solution.
728 - For Solaris must use POSIX awk.
729 - Want speed of writing to tape while despooling.
730 - Supported autochanger:
738 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
739 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
740 - Add regex from http://www.pcre.org to Bacula for Win32.
741 - Use only shell tools no make in CDROM package.
742 - Include within include does it work?
743 - Implement a Pool of type Cleaning?
744 - Implement VolReadTime and VolWriteTime in SD
745 - Modify Backing up Your Database to include a bootstrap file.
746 - Think about making certain database errors fatal.
747 - Look at correcting the time jump in the scheduler for daylight
748 savings time changes.
749 - Add a "real" timer to network connections.
750 - Promote to Full = Time period
751 - Check dates entered by user for correctness (month/day/... ranges)
752 - Compress restore Volume listing by date and first file.
753 - Look at patches/bacula_db.b2z postgresql that loops during restore.
755 - Perhaps add read/write programs and/or plugins to FileSets.
756 - How to handle backing up portables ...
757 - Add some sort of guaranteed Interval for upgrading jobs.
758 - Can we write the state file after every job terminates? On Win32
759 the system crashes and the state file is not updated.
762 Documentation to do: (any release a little bit at a time)
763 - Doc to do unmount before removing magazine.
764 - Alternative to static linking "ldd prog" save all binaries listed,
765 restore them and point LD_LIBRARY_PATH to them.
766 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
767 - Document query file format.
768 - Add more documentation for bsr files.
769 - Document problems with Verify and pruning.
770 - Document how to use multiple databases.
771 - VXA drives have a "cleaning required"
772 indicator, but Exabyte recommends preventive cleaning after every 75
775 In this context, it should be noted that Exabyte has a command-line
776 vxatool utility available for free download. (The current version is
777 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
778 test the drive, unload tapes, change drive settings, flash new firmware,
780 Of particular interest in this context is that vxatool <device> -i will
781 report, among other details, the time since last cleaning in tape motion
782 minutes. This information can be retrieved (and settings changed, for
783 that matter) through the generic-SCSI device even when Bacula has the
784 regular tape device locked. (Needless to say, I don't recommend
785 changing tape settings while a job is running.)
786 - Lookup HP cleaning recommendations.
787 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
788 - Document doing table repair
791 ===================================
792 - Add macro expansions in JobDefs.
793 Run Before Job = "SomeFile %{Level} %{Client}"
794 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
795 - Use non-blocking network I/O but if no data is available, use
797 - Use gather write() for network I/O.
798 - Autorestart on crash.
799 - Add bandwidth limiting.
800 - Add acks every once and a while from the SD to keep
801 the line from timing out.
802 - When an error in input occurs and conio beeps, you can back
803 up through the prompt.
804 - Detect fixed tape block mode during positioning by looking at
805 block numbers in btape "test". Possibly adjust in Bacula.
806 - Fix list volumes to output volume retention in some other
807 units, perhaps via a directive.
808 - If opening a tape in read/write mode fails attempt to open
809 it in read-only mode, and mark the tape for read only.
810 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
811 with multiple priorities.
812 - If you use restore replace=never, the directory attributes for
813 non-existent directories will not be restored properly.
815 - see lzma401.zip in others directory for new compression
817 - Minimal autochanger handling in Bacula and in btape.
818 - Look into how tar does not save sockets and the possiblity of
819 not saving them in Bacula (Martin Simmons reported this).
820 - Fix restore jobs so that multiple jobs can run if they
821 are not using the same tape(s).
822 - Allow the user to select JobType for manual pruning/purging.
823 - bscan does not put first of two volumes back with all info in
825 - Implement the FreeBSD nodump flag in chflags.
826 - Figure out how to make named console messages go only to that
827 console and to the non-restricted console (new console class?).
828 - Make restricted console prompt for password if *ask* is set or
829 perhaps if password is undefined.
830 - Implement "from ISO-date/time every x hours/days/weeks/months" in
833 ==== from Marc Schoechlin
834 - the help-command should be more verbose
835 (it should explain the paramters of the different
837 -> its time-comsuming to consult the manual anytime
838 you need a special parameter
839 -> maybe its more easy to maintain this, if the
840 descriptions of that commands are outsourced to
842 - the cd-command should allow complete paths
843 i.e. cd /foo/bar/foo/bar
844 -> if a customer mails me the path to a certain file,
845 its faster to enter the specified directory
846 - if the password is not configured in bconsole.conf
847 you should be asked for it.
848 -> sometimes you like to do restore on a customer-machine
849 which shouldnt know the password for bacula.
850 -> adding the password to the file favours admins
851 to forget to remove the password after usage
853 the protection of that file is less important
854 - long-listed-output of commands should be scrollable
855 like the unix more/less-command does
856 -> if someone runs 200 and more machines, the lists could
857 be a little long and complex
858 - command-output should be shown column by column
859 to reduce scrolling and to increase clarity
861 - lsmark should list the selected files with full
863 - wildcards for selecting and file and directories would be nice
864 - any actions should be interuptable with STRG+C
865 - command-expansion would be pretty cool
867 - When the replace Never option is set, new directory permissions
868 are not restored. See bug 213. To fix this requires creating a
869 list of newly restored directories so that those directory
870 permissions *can* be restored.
871 - Compaction of Disk space by "migrating" Volumes that have pruned
872 Jobs (what criteria? size, #jobs, time).
873 - Add prune all command
874 - Document fact that purge can destroy a part of a restore by purging
875 one volume while others remain valid -- perhaps mark Jobs.
876 - Add multiple-media-types.txt
877 - look at mxt-changer.html
878 - Make ? do a help command (no return needed).
879 - Implement restore directory.
880 - Document streams and how to implement them.
881 - Try not to re-backup a file if a new hard link is added.
882 - Add feature to backup hard links only, but not the data.
883 - Fix stream handling to be simpler.
884 - Add Priority and Bootstrap to Run a Job.
885 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
887 - Remove View FileSet button from Run a Job dialog.
888 - Handle prompt for restore job at end of Restore command.
889 - Add display of total selected files to Restore window.
890 - Add tree pane to left of window.
891 - Add progress meter.
892 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
893 - Document writing to a CD/DVD with Bacula.
894 - Add a "base" package to the window installer for pthreadsVCE.dll
895 which is needed by all packages.
896 - Add message to user to check for fixed block size when the forward
897 space test fails in btape.
898 - When unmarking a directory check if all files below are unmarked and
899 then remove the + flag -- in the restore tree.
900 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
901 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
902 - Revisit the question of multiple Volumes (disk) on a single device.
903 - Add a block copy option to bcopy.
904 - Investigate adding Mac Resource Forks.
905 - Finish work on Gnome restore GUI.
906 - Fix "llist jobid=xx" where no fileset or client exists.
907 - For each job type (Admin, Restore, ...) require only the really necessary
908 fields.- Pass Director resource name as an option to the Console.
909 - Add a "batch" mode to the Console (no unsolicited queries, ...).
910 - Add a .list all files in the restore tree (probably also a list all files)
911 Do both a long and short form.
912 - Allow browsing the catalog to see all versions of a file (with
913 stat data on each file).
914 - Restore attributes of directory if replace=never set but directory
916 - Use SHA1 on authentication if possible.
917 - See comtest-xxx.zip for Windows code to talk to USB.
918 - Add John's appended files:
919 Appended = { /files/server/logs/http/*log }
920 and such files would be treated as follows.On a FULL backup, they would
921 be backed up like any other file.On an INCREMENTAL backup, where a
922 previous INCREMENTAL or FULL was already in thecatalogue and the length
923 of the file wasgreater than the length of the last backup, only thedata
924 added since the last backup will be dumped.On an INCREMENTAL backup, if
925 the length of the file is less than thelength of the file with the same
926 name last backed up, the completefile is dumped.On Windows systems, with
927 creation date of files, we can be evensmarter about this and not count
928 entirely upon the length.On a restore, the full and all incrementals
929 since it will beapplied in sequence to restore the file.
930 - Check new HAVE_WIN32 open bits.
931 - Check if the tape has moved before writing.
932 - Handling removable disks -- see below:
933 - Keep track of tape use time, and report when cleaning is necessary.
934 - Add FromClient and ToClient keywords on restore command (or
935 BackupClient RestoreClient).
936 - Implement a JobSet, which groups any number of jobs. If the
937 JobSet is started, all the jobs are started together.
938 Allow Pool, Level, and Schedule overrides.
939 - Enhance cancel to timeout BSOCK packets after a specific delay.
940 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
941 ua_status.!!! Thanks to Alan Brown for this tip.
942 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
943 correctly for multiple simultaneous jobs.
944 - Correct code so that FileSet MD5 is calculated for < and | filename
946 - Implement the Media record flag that indicates that the Volume does disk
948 - Implement VolAddr, which is used when Volume is addressed like a disk,
949 and form it from VolFile and VolBlock.
950 - Make multiple restore jobs for multiple media types specifying
951 the proper storage type.
952 - Fix fast block rejection (stored/read_record.c:118). It passes a null
953 pointer (rec) to try_repositioning().
954 - Look at extracting Win data from BackupRead.
955 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
956 which would take precidence over the Catalog "JobRetention".
957 - Implement Label Format in Add and Label console commands.
958 - Possibly up network buffers to 65K. Put on variable.
959 - Put email tape request delays on one or more variables. User wants
960 to cancel the job after a certain time interval. Maximum Mount Wait?
961 - Job, Client, Device, Pool, or Volume?
962 Is it possible to make this a directive which is *optional* in multiple
963 resources, like Level? If so, I think I'd make it an optional directive
964 in Job, Client, and Pool, with precedence such that Job overrides Client
965 which in turn overrides Pool.
967 - New Storage specifications:
968 - Want to write to multiple storage devices simultaneously
969 - Want to write to multiple storage devices sequentially (in one job)
970 - Want to read/write simultaneously
971 - Key is MediaType -- it must match
973 Passed to SD as a sort of BSR record called Storage Specification
977 MediaType -> Next MediaType
979 Device -> Next Device
981 Allow multiple Storage specifications
989 Allow Multiple Pool specifications (note, Pool currently
991 Allow Multiple MediaType specifications in Dir conf
992 Allow Multiple Device specifications in Dir conf
993 Perhaps keep this in a single SSR
994 Tie a Volume to a specific device by using a MediaType that
995 is contained in only one device.
996 In SD allow Device to have Multiple MediaTypes
998 - Ideas from Jerry Scharf:
999 First let's point out some big pluses that bacula has for this
1001 more importantly it's active. Thank you so much for that
1002 even more important, it's not flaky
1003 it has an open access catalog, opening many possibilities
1004 it's pushing toward heterogeneous systems capability
1006 Macintosh file client
1007 macs are an interesting niche, but I fear a server is a rathole
1008 working bare iron recovery for windows
1009 the option for inc/diff backups not reset on fileset revision
1010 a) use both change and inode update time against base time
1011 b) do the full catalog check (expensive but accurate)
1012 sizing guide (how much system is needed to back up N systems/files)
1013 consultants on using bacula in building a disaster recovery system
1014 an integration guide
1015 or how to get at fancy things that one could do with bacula
1016 logwatch code for bacula logs (or similar)
1017 linux distro inclusion of bacula (brings good and bad, but necessary)
1018 win2k/XP server capability (icky but you asked)
1019 support for Oracle database ??
1021 - Look at adding SQL server and Exchange support for Windows.
1022 - Make dev->file and dev->block_num signed integers so that -1 can
1023 be an invalid value which happens with BSR.
1024 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1025 is needed to properly specify ranges.
1026 - Add progress of files/bytes to SD and FD.
1027 - Print warning message if FileId > 4 billion
1028 - do a "messages" before the first prompt in Console
1029 - Client does not show busy during Estimate command.
1030 - Implement Console mtx commands.
1031 - Implement a Mount Command and an Unmount Command where
1032 the users could specify a system command to be performed
1033 to do the mount, after which Bacula could attempt to
1034 read the device. This is for Removeable media such as a CDROM.
1035 - Most likely, this mount command would be invoked explicitly
1036 by the user using the current Console "mount" and "unmount"
1037 commands -- the Storage Daemon would do the right thing
1038 depending on the exact nature of the device.
1039 - As with tape drives, when Bacula wanted a new removable
1040 disk mounted, it would unmount the old one, and send a message
1041 to the user, who would then use "mount" as described above
1042 once he had actually inserted the disk.
1043 - Implement dump/print label to UA
1044 - Spool to disk only when the tape is full, then when a tape is hung move
1046 - bextract is sending everything to the log file ****FIXME****
1047 - Allow multiple Storage specifications (or multiple names on
1048 a single Storage specification) in the Job record. Thus a job
1049 can be backed up to a number of storage devices.
1050 - Implement some way for the File daemon to contact the Director
1051 to start a job or pass its DHCP obtained IP number.
1052 - Implement a query tape prompt/replace feature for a console
1053 - Copy console @ code to gnome2-console
1054 - Make AES the only encryption algorithm see
1055 http://csrc.nist.gov/CryptoToolkit/aes/). It's
1056 an officially adopted standard, has survived peer
1057 review, and provides keys up to 256 bits.
1058 - Take a careful look at SetACL http://setacl.sourceforge.net
1059 - Make tree walk routines like cd, ls, ... more user friendly
1060 by handling spaces better.
1061 - Make sure that Bacula rechecks the tape after the 20 min wait.
1062 - Set IO_NOWAIT on Bacula TCP/IP packets.
1063 - Try doing a raw partition backup and restore by mounting a
1065 - From Lars Kellers:
1066 Yes, it would allow to highly automatic the request for new tapes. If a
1067 tape is empty, bacula reads the barcodes (native or simulated), and if
1068 an unused tape is found, it runs the label command with all the
1069 necessary parameters.
1071 By the way can bacula automatically "move" an empty/purged volume say
1072 in the "short" pool to the "long" pool if this pool runs out of volume
1074 - What to do about "list files job=xxx".
1075 - Get and test MySQL 4.0
1076 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1077 file descriptor leak in Bacula.
1078 - Implement WrapCounters in Counters.
1079 - Add heartbeat from FD to SD if hb interval expires.
1080 - Can we dynamically change FileSets?
1081 - If pool specified to label command and Label Format is specified,
1082 automatically generate the Volume name.
1083 - Why can't SQL do the filename sort for restore?
1084 - Add ExhautiveRestoreSearch
1085 - Look at the possibility of loading only the necessary
1086 data into the restore tree (i.e. do it one directory at a
1087 time as the user walks through the tree).
1088 - Possibly use the hash code if the user selects all for a restore command.
1089 - Fix "restore all" to bypass building the tree.
1090 - Prohibit backing up archive device (findlib/find_one.c:128)
1091 - Implement Release Device in the Job resource to unmount a drive.
1092 - Implement Acquire Device in the Job resource to mount a drive,
1093 be sure this works with admin jobs so that the user can get
1094 prompted to insert the correct tape. Possibly some way to say to
1095 run the job but don't save the files.
1096 - Make things like list where a file is saved case independent for
1099 - Use autochanger to handle multiple devices.
1100 - On Windows with very long path names, it may be impossible to create
1101 a file (and thus restore it) because the total length is too long.
1102 We must cd into the directory then create the file without the
1104 - Implement a Recycle command
1105 - Test a second language e.g. french.
1106 - Start working on Base jobs.
1107 - Implement UnsavedFiles DB record.
1108 - From Phil Stracchino:
1109 It would probably be a per-client option, and would be called
1110 something like, say, "Automatically purge obsoleted jobs". What it
1111 would do is, when you successfully complete a Differential backup of a
1112 client, it would automatically purge all Incremental backups for that
1113 client that are rendered redundant by that Differential. Likewise,
1114 when a Full backup on a client completed, it would automatically purge
1115 all Differential and Incremental jobs obsoleted by that Full backup.
1116 This would let people minimize the number of tapes they're keeping on
1117 hand without having to master the art of retention times.
1118 - When doing a Backup send all attributes back to the Director, who
1119 would then figure out what files have been deleted.
1120 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1121 explicit permission to do so. It should also mark the tape in error
1122 if there is an error.
1123 - Cancel waiting for Client connect in SD if FD goes away.
1125 - Implement timeout in response() when it should come quickly.
1126 - Implement a Slot priority (loaded/not loaded).
1127 - Implement "vacation" Incremental only saves.
1128 - Implement create "FileSet"?
1129 - Add prefixlinks to where or not where absolute links to FD.
1130 - Issue message to mount a new tape before the rewind.
1131 - Simplified client job initiation for portables.
1132 - If SD cannot open a drive, make it periodically retry.
1133 - Add more of the config info to the tape label.
1135 - If tape is marked read-only, then try opening it read-only rather than
1136 failing, and remember that it cannot be written.
1137 - Refine SD waiting output:
1138 Device is being positioned
1139 > Device is being positioned for append
1140 > Device is being positioned to file x
1142 - Figure out some way to estimate output size and to avoid splitting
1143 a backup across two Volumes -- this could be useful for writing CDROMs
1144 where you really prefer not to have it split -- not serious.
1145 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1146 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1147 actual data on the Volume and compare it.
1148 - Implement Bacula plugins -- design API
1149 - Make bcopy read through bad tape records.
1150 - Program files (i.e. execute a program to read/write files).
1151 Pass read date of last backup, size of file last time.
1152 - Add Signature type to File DB record.
1153 - CD into subdirectory when open()ing files for backup to
1154 speed up things. Test with testfind().
1155 - Priority job to go to top of list.
1156 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1157 - Implement some way for the Console to dynamically create a job.
1158 - Solaris -I on tar for include list

1258 report resource where report=group of messages
1259 - enhance scan_attrib and rename scan_jobtype, and
1260 fill in code for "since" option
1261 - Director needs a time after which the report status is sent
1262 anyway -- or better yet, a retry time for the job.
1263 - Don't reschedule a job if previous incarnation is still running.
1264 - Some way to automatically backup everything is needed????
1265 - Need a structure for pending actions:
1267 - termination status (part of buffered msgs?)
1269 Read, Write, Clean, Delete
1270 - Login to Bacula; Bacula users with different permissions:
1271 owner, group, user, quotas
1272 - Store info on each file system type (probably in the job header on tape.
1273 This could be the output of df; or perhaps some sort of /etc/mtab record.

1276 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1277 To: <kern@sibbald.com>
1278 Subject: RE: [Bacula-users] future large programming jobs
1279 Date: Thu, 26 Feb 2004 11:34:54 -0600
1281 I noticed the subject thread and thought I would offer the following
1282 merely as sources of ideas, i.e. something to think about, not even as
1283 strong as a request. In my former life (before retiring) I often
1284 dealt with backups and storage management issues/products as a
1285 developer and as a consultant. I am currently migrating my personal
1286 network from amanda to bacula specifically because of the ability to
1287 cross media boundaries during storing backups.
1288 Are you familiar with the commercial product called ADSM (I think IBM
1289 now sells it under the Tivoli label)? It has a couple of interesting
1290 ideas that may apply to the following topics.
1292 1. Migration: Consider that when you need to restore a system, there
1293 may be pressure to hurry. If all the information for a single client
1294 can eventually end up on the same media (and in chronological order),
1295 the restore is facillitated by not having to search past information
1296 from other clients. ADSM has the concept of "client affinity" that
1297 may be associated with it's storage pools. It seems to me that this
1298 concept (as an optional feature) might fit in your architecture for
1301 ADSM also has the concept of defining one or more storage pools as
1302 "copy pools" (almost mirrors, but only in the sense of contents).
1303 These pools provide the ability to have duplicte data stored both
1304 onsite and offsite. The copy process can be scheduled to be handled
1305 by their storage manager during periods when there is no backup
1306 activity. Again, the migration process might be a place to consider
1307 implementing something like this.
1310 > It strikes me that it would be very nice to be able to do things
1312 > have the Job(s) backing up the machines run, and once they have all

1318 > mechanism described below would probably make it very easy.
1320 This is the goal. In the first step (before events), you simply
1322 the Migration to tape later.
1324 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1325 the database. Once a file (unique by path and metadata such as dates,
1326 size, ownership, etc.) is in a copy pool, no more copies are made. In
1327 other words, when you start ADSM, it begins like your concept of a
1328 base job. After that it is in the "incremental" mode. You can
1329 configure the number of "generations" of files to be retained, plus a
1330 retention date after which even old generations are purged. The
1331 database tracks the contents of media and projects the percentage of
1332 each volume that is valid. When the valid content of a volume drops
1333 below a configured percentage, the valid data are migrated to another
1334 volume and the old volume is marked as empty. Note, this requires
1335 ADSM to have an idea of the contents of a client, i.e. marking the
1336 database when an existing file was deleted, but this would solve your
1337 issue of restoring a client without restoring deleted files.
1339 This is pretty far from what bacula now does, but if you are going to
1340 rip things up for Base jobs,.....
1341 Also, the benefits of this are huge for very large shops, especially
1342 with media robots, but are a pain for shops with manual media
1346 > Base jobs sound pretty useful, but I'm not dying for them.
1348 Nobody is dying for them, but when you see what it does, you will die
1351 3. Restoring deleted files: Since I think my comments in (2) above
1352 have low probability of implementation, I'll also suggest that you
1353 could approach the issue of deleted files by a mechanism of having the
1354 fd report to the dir, a list of all files on the client for every
1355 backup job. The dir could note in the database entry for each file
1356 the date that the file was seen. Then if a restore as of date X takes
1357 place, only files that exist from before X until after X would be
1358 restored. Probably the major cost here is the extra date container in
1359 each row of the files table.
1361 Thanks for "listening". I hope some of this helps. If you want to
1362 contact me, please send me an email - I read some but not all of the
1363 mailing list traffic and might miss a reply there.
1365 Please accept my compliments for bacula. It is doing a great job for
1366 me!! I sympathize with you in the need to wrestle with excelence in
1367 execution vs. excelence in feature inclusion.
1372 ==============================
1375 - Design at hierarchial storage for Bacula. Migration and Clone.
1376 - Implement FSM (File System Modules).
1377 - Audit M_ error codes to ensure they are correct and consistent.
1378 - Add variable break characters to lex analyzer.
1379 Either a bit mask or a string of chars so that
1380 the caller can change the break characters.
1381 - Make a single T_BREAK to replace T_COMMA, etc.
1382 - Ensure that File daemon and Storage daemon can
1383 continue a save if the Director goes down (this
1384 is NOT currently the case). Must detect socket error,
1385 buffer messages for later.
1386 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1387 - Add ability to backup to two Storage devices (two SD sessions) at
1388 the same time -- e.g. onsite, offsite.
1389 - Add the ability to consolidate old backup sets (basically do a restore
1390 to tape and appropriately update the catalog). Compress Volume sets.
1391 Might need to spool via file is only one drive is available.
1392 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1393 someway to do so with every volume that has less than x% valid
1397 Migration: Move a backup from one Volume to another
1398 Clone: Copy a backup -- two Volumes
1400 Bacula Migration is based on Jobs (apparently Networker is file by file).
1402 Migration triggered by:
1406 Highwater mark (keep total size)
1411 ======================================================
1413 It is somewhat like a Full save becomes an incremental since
1414 the Base job (or jobs) plus other non-base files.
1416 - A Base backup is same as Full backup, just different type.
1417 - New BaseFiles table that contains:
1419 BaseJobId - Base JobId referenced for this FileId (needed ???)
1420 JobId - JobId currently running
1421 FileId - File not backed up, exists in Base Job
1422 FileIndex - FileIndex from Base Job.
1423 i.e. for each base file that exists but is not saved because
1424 it has not changed, the File daemon sends the JobId, BaseId,
1425 FileId, FileIndex back to the Director who creates the DB entry.
1426 - To initiate a Base save, the Director sends the FD
1427 the FileId, and full filename for each file in the Base.
1428 - When the FD finds a Base file, he requests the Director to
1429 send him the full File entry (stat packet plus MD5), or
1430 conversely, the FD sends it to the Director and the Director
1431 says yes or no. This can be quite rapid if the FileId is kept
1432 by the FD for each Base Filename.
1433 - It is probably better to have the comparison done by the FD
1434 despite the fact that the File entry must be sent across the
1436 - An alternative would be to send the FD the whole File entry
1437 from the start. The disadvantage is that it requires a lot of
1438 space. The advantage is that it requires less communications
1440 - The Job record must be updated to indicate that one or more
1442 - At end of Job, FD returns:
1443 1. Count of base files/bytes not written to tape (i.e. matches)
1444 2. Count of base file that were saved i.e. had changed.
1445 - No tape record would be written for a Base file that matches, in the
1446 same way that no tape record is written for Incremental jobs where
1447 the file is not saved because it is unchanged.
1448 - On a restore, all the Base file records must explicitly be
1449 found from the BaseFile tape. I.e. for each Full save that is marked
1450 to have one or more Base Jobs, search the BaseFile for all occurrences
1452 - An optimization might be to make the BaseFile have:
1458 This would avoid the need to explicitly fetch each File record for
1459 the Base job. The Base Job record will be fetched to get the
1460 VolSessionId and VolSessionTime.
1461 =========================================================
1464 ==========================================================
1466 For each Incremental job that is run, there may be files that
1467 were found but not saved because they were locked (this applies
1468 only to Windows). Such a system could send back to the Director
1469 a list of Unsaved files.
1471 - New UnSavedFiles table that contains:
1475 - Then in the next Incremental job, the list of Unsaved Files will be
1476 feed to the FD, who will ensure that they are explicitly chosen even
1477 if standard date/time check would not have selected them.

1519 (just to verify it remembers where it came from, however it can be

1522 There needs to be a table of drive # to devices somewhere - If there are
1523 multiple changers or drives there may not be a 1:1 correspondance between
1524 changer drive number and system device name - and depending on the way the
1525 drives are hooked up to scsi busses, they may not be linearly numbered
1526 from an offset point either.something like
1528 Autochanger drives = 2
1529 Autochanger drive 0 = /dev/nst1
1530 Autochanger drive 1 = /dev/nst2
1531 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1532 times, not just for multidrive changers. For a 1 drive changer, that's
1538 MTX's manpage (1.2.15):
1539 unload [<slotnum>] [ <drivenum> ]
1540 Unloads media from drive <drivenum> into slot
1541 <slotnum>. If <drivenum> is omitted, defaults to
1542 drive 0 (as do all commands). If <slotnum> is
1543 omitted, defaults to the slot that the drive was
1544 loaded from. Note that there's currently no way
1545 to say 'unload drive 1's media to the slot it
1546 came from', other than to explicitly use that
1547 slot number as the destination.AB

1585 Handling removable disks
1587 From: Karl Cunningham <karlc@keckec.com>
1589 My backups are only to hard disk these days, in removable bays. This is my
1590 idea of how a backup to hard disk would work more smoothly. Some of these
1591 things Bacula does already, but I mention them for completeness. If others
1592 have better ways to do this, I'd like to hear about it.
1594 1. Accommodate several disks, rotated similar to how tapes are. Identified
1595 by partition volume ID or perhaps by the name of a subdirectory.
1596 2. Abort & notify the admin if the wrong disk is in the bay.
1597 3. Write backups to different subdirectories for each machine to be backed
1599 4. Volumes (files) get created as needed in the proper subdirectory, one
1601 5. When a disk is recycled, remove or zero all old backup files. This is
1602 important as the disk being recycled may be close to full. This may be
1603 better done manually since the backup files for many machines may be
1604 scattered in many subdirectories.
1609 - Make sure that all do_prompt() calls in Dir check for
1610 -1 (error) and -2 (cancel) returns.
1611 - Fix foreach_jcr() to have free_jcr() inside next().
1612 jcr=jcr_walk_start();
1613 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1616 - A Volume taken from Scratch should take on the retention period
1618 - Correct doc for Maximum Changer Wait (and others) accepting only
1620 - Implement status that shows why a job is being held in reserve, or
1621 rather why none of the drives are suitable.
1622 - Implement a way to disable a drive (so you can use the second
1623 drive of an autochanger, and the first one will not be used or
1625 - Make sure Maximum Volumes is respected in Pools when adding
1626 Volumes (e.g. when pulling a Scratch volume).
1627 - Keep same dcr when switching device ...
1628 - Implement code that makes the Dir aware that a drive is an
1629 autochanger (so the user doesn't need to use the Autochanger = yes
1631 - Make catalog respect ACL.
1632 - Add recycle count to Media record.
1633 - Add initial write date to Media record.
1634 - Fix store_yesno to be store_bitmask.

1658 and verify that other buffers cannot overrun.
1659 - Implement VolumeState as discussed with Arno.
