15 - During tests with the 260 char fix code, I found one problem:
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
18 the next job (create bootstrap file will fail). Here is the
19 workaround: specify absolute working and pid directory in

72 .show device=xxx lists information from one storage device, including
73 devices (I'm not even sure that information exists in the DIR...)
74 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
75 better machine-readable output like "Ok" or "Error busy"

81 - Get Perl replacement for bregex.c
82 - Given all the problems with FIFOs, I think the solution is to do something a
83 little different, though I will look at the code and see if there is not some
84 simple solution (i.e. some bug that was introduced). What might be a better
85 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
86 write data to a program rather than the FIFO. For example, suppose you
91 Then, I could imagine if you backup and restore this file with a direct
92 reference as is currently done for fifos, instead, during backup Bacula will
95 /home/kern/my-fifo.backup
97 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
100 /home/kern/my-fifo.restore
102 and send the data backed up to stdout. These programs can either be an
103 executable or a shell script and they need only read/write to stdin/stdout.
105 I think this would give a lot of flexibility to the user without making any
106 significant changes to Bacula.

123 === Migration from David ===
124 What I'd like to see:
127 Name = "<poolname>-migrate"
131 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
132 Client | PoolResidence | Volume | JobName | SQLquery
133 Migration Selection Pattern = "regexp"
134 Next Pool = <override>
137 There should be no need for a Level (migration is always Full, since you
138 don't calculate differential/incremental differences for migration),
139 Storage should be determined by the volume types in the pool, and Client
140 is really a selection issue. Migration should always occur to the
141 NextPool defined in the pool definition. If no nextpool is defined, the
142 job should end with a reason of "no place to go". If Next Pool statement
143 is present, we override the check in the pool definition and use the
146 Here's how I'd define Migration Selection Types:
149 Client -- Migrate data from selected client only. Migration Selection
150 Pattern regexp provides pattern to select client names, eg ^FS00* makes
151 all client names starting with FS00 eligible for migration.
153 Jobname -- Migration all jobs matching name. Migration Selection Pattern
154 regexp provides pattern to select jobnames existing in pool.
156 Volume -- Migrate all data on specified volumes. Migration Selection
157 Pattern regexp provides selection criteria for volumes to be migrated.
158 Volumes must exist in pool to be eligible for migration.
162 LowestUtil -- Identify the volume in the pool with the least data on it
163 and empty it. No Migration Selection Pattern required.
165 OldestVol -- Identify the LRU volume with data written, and empty it. No
166 Migration Selection Pattern required.
168 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
169 (starting with most full volumes) until pool occupancy drops below
170 <lowmig>. Pool highmig and lowmig values are in pool definition, no
171 Migration Selection Pattern required.
175 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
176 Migration Selection Pattern contains SQL query to execute; should return
177 a list of 1 or more jobuids to migrate.
179 PoolResidence -- Migrate data sitting in pool for longer than
180 PoolResidence value in pool definition. Migration Selection Pattern
181 optional; if specified, override value in pool definition (value in

300 - The btape fill command does not seem to use the Autochanger
301 - Make Windows installer default to system disk drive.

330 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
331 - Implement a mode that says when a hard read error is

334 that fails, skip to the next file and try again, ...

348 - Look at simplifying File exclusions.

350 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and

360 failed backup as a sort of "base" job.

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

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

586 - Win32 systems with FAT32 can be much slower than NTFS for
587 more than 1000 files per directory.

598 === From Carsten Menke <bootsy52@gmx.net>
600 Following is a list of what I think in the situations where I'm faced with,
601 could be a usefull enhancement to bacula, which I'm certain other users will
602 benefit from as well.
604 1. NextJob/NextJobs Directive within a Job Resource in the form of
605 NextJobs = job1,job2.
608 I currently solved the problem with running multiple jobs each after each
609 by setting the Max Wait Time for a job to 8 hours, and give
610 the jobs different Priorities. However, there scenarios where
611 1 Job is directly depending on another job, so if the former job fails,
612 the job after it needn't to be run
613 while maybe other jobs should run despite of that
616 A Backup Job and a Verify job, if the backup job fails there is no need to run
617 the verify job, as the backup job already failed. However, one may like
618 to backup the Catalog to disk despite of that the main backup job failed.
621 I see that this is related to the Event Handlers which are on the ToDo
622 list, also it is maybe a good idea to check for the return value and
623 execute different actions based on the return value
626 3. offline capability to bconsole
629 Currently I use a script which I execute within the last Job via the
630 RunAfterJob Directive, to release and eject the tape.
631 So I have to call bconsole "release=Storage-Name" and afterwards
632 mt -f /dev/nst0 eject to get the tape out.
634 If I have multiple Storage Devices, than these may not be /dev/nst0 and
635 I have to modify the script or call it with parameters etc.
636 This would actually not be needed, as everything is already defined
637 in bacula-sd.conf and if I can invoke bconsole with the
638 storage name via $1 in the script than I'm done and information is
641 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
645 For the reason mentioned in 3. to have the ability to call a
646 script with /scripts/foobar %s and in the script use $1
647 to pass the Storage Name to bconsole
649 5. Setting Volume State within a Job Resource
652 Instead of using "Maximum Volume Jobs" in the Pool Resource,
653 I would have the possibilty to define
654 in a Job Resource that after this certain job is run, the Volume State
655 should be set to "Volume State = Used", this give more flexibility (IMHO).
657 6. Localization of Bacula Messages
660 Unfortunatley many,many people I work with don't speak english very well.
661 So if at least the Reporting messages would be localized then they
662 would understand that they have to change the tape,etc. etc.
664 I volunteer to do the german translations, and if I can convince my wife also
665 french and Morre (western african language).
667 7. OK, this is evil, probably bound to security risks and maybe not possible
668 due to the design of bacula.
670 Implementation of Backtics ( `command` ) for shell comand execution to
671 the "Label Format" Directive.
675 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
676 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
677 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
678 the localized name for the day of the week appended to the
679 format string. Then I have the tape labeled automatically with weekday
680 name in the correct language.
682 - Yes, that is surely the case. I probably should turn those into Warning
683 errors. In addition, you just made me think that it might not be bad to
684 add an option to check the file size after backing up the file and
685 report if it changes. This would be done as an option because it would
688 Kern, good idea. If you do do that, mention in the output: file
689 shrunk, or file expanded, just to make it obvious to the user
690 (without having to the refer to file size), just how the file size
693 Would this option be for all file, or just one file? Or a fileset?
694 - Make output from status use html table tags for nicely
695 presenting in a browser.
696 - Can one write tapes faster with 8192 byte block sizes?
697 - Document security problems with the same password for everyone in
698 rpm and Win32 releases.
699 - Browse generations of files.
700 - I've seen an error when my catalog's File table fills up. I
701 then have to recreate the File table with a larger maximum row
702 size. Relevant information is at
703 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
704 "Installing and Configuring MySQL" chapter should talk a bit
705 about this potential problem, and recommend a solution.
706 - For Solaris must use POSIX awk.
707 - Want speed of writing to tape while despooling.
708 - Supported autochanger:
716 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
717 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
718 - Add regex from http://www.pcre.org to Bacula for Win32.
719 - Use only shell tools no make in CDROM package.
720 - Include within include does it work?
721 - Implement a Pool of type Cleaning?
722 - Implement VolReadTime and VolWriteTime in SD
723 - Modify Backing up Your Database to include a bootstrap file.
724 - Think about making certain database errors fatal.
725 - Look at correcting the time jump in the scheduler for daylight
726 savings time changes.
727 - Add a "real" timer to network connections.
728 - Promote to Full = Time period
729 - Check dates entered by user for correctness (month/day/... ranges)
730 - Compress restore Volume listing by date and first file.
731 - Look at patches/bacula_db.b2z postgresql that loops during restore.
733 - Perhaps add read/write programs and/or plugins to FileSets.
734 - How to handle backing up portables ...
735 - Add some sort of guaranteed Interval for upgrading jobs.
736 - Can we write the state file after every job terminates? On Win32
737 the system crashes and the state file is not updated.
740 Documentation to do: (any release a little bit at a time)
741 - Doc to do unmount before removing magazine.
742 - Alternative to static linking "ldd prog" save all binaries listed,
743 restore them and point LD_LIBRARY_PATH to them.
744 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
745 - Document query file format.
746 - Add more documentation for bsr files.
747 - Document problems with Verify and pruning.
748 - Document how to use multiple databases.
749 - VXA drives have a "cleaning required"
750 indicator, but Exabyte recommends preventive cleaning after every 75
753 In this context, it should be noted that Exabyte has a command-line
754 vxatool utility available for free download. (The current version is
755 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
756 test the drive, unload tapes, change drive settings, flash new firmware,
758 Of particular interest in this context is that vxatool <device> -i will
759 report, among other details, the time since last cleaning in tape motion
760 minutes. This information can be retrieved (and settings changed, for
761 that matter) through the generic-SCSI device even when Bacula has the
762 regular tape device locked. (Needless to say, I don't recommend
763 changing tape settings while a job is running.)
764 - Lookup HP cleaning recommendations.
765 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
766 - Document doing table repair
769 ===================================
770 - Add macro expansions in JobDefs.
771 Run Before Job = "SomeFile %{Level} %{Client}"
772 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
773 - Use non-blocking network I/O but if no data is available, use
775 - Use gather write() for network I/O.
776 - Autorestart on crash.
777 - Add bandwidth limiting.
778 - Add acks every once and a while from the SD to keep
779 the line from timing out.
780 - When an error in input occurs and conio beeps, you can back
781 up through the prompt.
782 - Detect fixed tape block mode during positioning by looking at
783 block numbers in btape "test". Possibly adjust in Bacula.
784 - Fix list volumes to output volume retention in some other
785 units, perhaps via a directive.
786 - If opening a tape in read/write mode fails attempt to open
787 it in read-only mode, and mark the tape for read only.
788 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
789 with multiple priorities.
790 - If you use restore replace=never, the directory attributes for
791 non-existent directories will not be restored properly.
793 - see lzma401.zip in others directory for new compression
795 - Minimal autochanger handling in Bacula and in btape.
796 - Look into how tar does not save sockets and the possiblity of
797 not saving them in Bacula (Martin Simmons reported this).
798 - Fix restore jobs so that multiple jobs can run if they
799 are not using the same tape(s).
800 - Allow the user to select JobType for manual pruning/purging.
801 - bscan does not put first of two volumes back with all info in
803 - Implement the FreeBSD nodump flag in chflags.
804 - Figure out how to make named console messages go only to that
805 console and to the non-restricted console (new console class?).
806 - Make restricted console prompt for password if *ask* is set or
807 perhaps if password is undefined.
808 - Implement "from ISO-date/time every x hours/days/weeks/months" in
811 ==== from Marc Schoechlin
812 - the help-command should be more verbose
813 (it should explain the paramters of the different
815 -> its time-comsuming to consult the manual anytime
816 you need a special parameter
817 -> maybe its more easy to maintain this, if the
818 descriptions of that commands are outsourced to
820 - the cd-command should allow complete paths
821 i.e. cd /foo/bar/foo/bar
822 -> if a customer mails me the path to a certain file,
823 its faster to enter the specified directory
824 - if the password is not configured in bconsole.conf
825 you should be asked for it.
826 -> sometimes you like to do restore on a customer-machine
827 which shouldnt know the password for bacula.
828 -> adding the password to the file favours admins
829 to forget to remove the password after usage
831 the protection of that file is less important
832 - long-listed-output of commands should be scrollable
833 like the unix more/less-command does
834 -> if someone runs 200 and more machines, the lists could
835 be a little long and complex
836 - command-output should be shown column by column
837 to reduce scrolling and to increase clarity
839 - lsmark should list the selected files with full
841 - wildcards for selecting and file and directories would be nice
842 - any actions should be interuptable with STRG+C
843 - command-expansion would be pretty cool
845 - When the replace Never option is set, new directory permissions
846 are not restored. See bug 213. To fix this requires creating a
847 list of newly restored directories so that those directory
848 permissions *can* be restored.
849 - Compaction of Disk space by "migrating" Volumes that have pruned
850 Jobs (what criteria? size, #jobs, time).
851 - Add prune all command
852 - Document fact that purge can destroy a part of a restore by purging
853 one volume while others remain valid -- perhaps mark Jobs.
854 - Add multiple-media-types.txt
855 - look at mxt-changer.html
856 - Make ? do a help command (no return needed).
857 - Implement restore directory.
858 - Document streams and how to implement them.
859 - Try not to re-backup a file if a new hard link is added.
860 - Add feature to backup hard links only, but not the data.
861 - Fix stream handling to be simpler.
862 - Add Priority and Bootstrap to Run a Job.
863 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
865 - Remove View FileSet button from Run a Job dialog.
866 - Handle prompt for restore job at end of Restore command.
867 - Add display of total selected files to Restore window.
868 - Add tree pane to left of window.
869 - Add progress meter.
870 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
871 - Document writing to a CD/DVD with Bacula.
872 - Add a "base" package to the window installer for pthreadsVCE.dll
873 which is needed by all packages.
874 - Add message to user to check for fixed block size when the forward
875 space test fails in btape.
876 - When unmarking a directory check if all files below are unmarked and
877 then remove the + flag -- in the restore tree.
878 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
879 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
880 - Revisit the question of multiple Volumes (disk) on a single device.
881 - Add a block copy option to bcopy.
882 - Investigate adding Mac Resource Forks.
883 - Finish work on Gnome restore GUI.
884 - Fix "llist jobid=xx" where no fileset or client exists.
885 - For each job type (Admin, Restore, ...) require only the really necessary
886 fields.- Pass Director resource name as an option to the Console.
887 - Add a "batch" mode to the Console (no unsolicited queries, ...).
888 - Add a .list all files in the restore tree (probably also a list all files)
889 Do both a long and short form.
890 - Allow browsing the catalog to see all versions of a file (with
891 stat data on each file).
892 - Restore attributes of directory if replace=never set but directory
894 - Use SHA1 on authentication if possible.
895 - See comtest-xxx.zip for Windows code to talk to USB.
896 - Add John's appended files:
897 Appended = { /files/server/logs/http/*log }
898 and such files would be treated as follows.On a FULL backup, they would
899 be backed up like any other file.On an INCREMENTAL backup, where a
900 previous INCREMENTAL or FULL was already in thecatalogue and the length
901 of the file wasgreater than the length of the last backup, only thedata
902 added since the last backup will be dumped.On an INCREMENTAL backup, if
903 the length of the file is less than thelength of the file with the same
904 name last backed up, the completefile is dumped.On Windows systems, with
905 creation date of files, we can be evensmarter about this and not count
906 entirely upon the length.On a restore, the full and all incrementals
907 since it will beapplied in sequence to restore the file.
908 - Check new HAVE_WIN32 open bits.
909 - Check if the tape has moved before writing.
910 - Handling removable disks -- see below:
911 - Keep track of tape use time, and report when cleaning is necessary.
912 - Add FromClient and ToClient keywords on restore command (or
913 BackupClient RestoreClient).
914 - Implement a JobSet, which groups any number of jobs. If the
915 JobSet is started, all the jobs are started together.
916 Allow Pool, Level, and Schedule overrides.
917 - Enhance cancel to timeout BSOCK packets after a specific delay.
918 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
919 ua_status.!!! Thanks to Alan Brown for this tip.
920 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
921 correctly for multiple simultaneous jobs.
922 - Correct code so that FileSet MD5 is calculated for < and | filename
924 - Implement the Media record flag that indicates that the Volume does disk
926 - Implement VolAddr, which is used when Volume is addressed like a disk,
927 and form it from VolFile and VolBlock.
928 - Make multiple restore jobs for multiple media types specifying
929 the proper storage type.
930 - Fix fast block rejection (stored/read_record.c:118). It passes a null
931 pointer (rec) to try_repositioning().
932 - Look at extracting Win data from BackupRead.
933 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
934 which would take precidence over the Catalog "JobRetention".
935 - Implement Label Format in Add and Label console commands.
936 - Possibly up network buffers to 65K. Put on variable.
937 - Put email tape request delays on one or more variables. User wants
938 to cancel the job after a certain time interval. Maximum Mount Wait?
939 - Job, Client, Device, Pool, or Volume?
940 Is it possible to make this a directive which is *optional* in multiple
941 resources, like Level? If so, I think I'd make it an optional directive
942 in Job, Client, and Pool, with precedence such that Job overrides Client
943 which in turn overrides Pool.
945 - New Storage specifications:
946 - Want to write to multiple storage devices simultaneously
947 - Want to write to multiple storage devices sequentially (in one job)
948 - Want to read/write simultaneously
949 - Key is MediaType -- it must match
951 Passed to SD as a sort of BSR record called Storage Specification
955 MediaType -> Next MediaType
957 Device -> Next Device
959 Allow multiple Storage specifications
967 Allow Multiple Pool specifications (note, Pool currently
969 Allow Multiple MediaType specifications in Dir conf
970 Allow Multiple Device specifications in Dir conf
971 Perhaps keep this in a single SSR
972 Tie a Volume to a specific device by using a MediaType that
973 is contained in only one device.
974 In SD allow Device to have Multiple MediaTypes
976 - Ideas from Jerry Scharf:
977 First let's point out some big pluses that bacula has for this
979 more importantly it's active. Thank you so much for that
980 even more important, it's not flaky
981 it has an open access catalog, opening many possibilities
982 it's pushing toward heterogeneous systems capability
984 Macintosh file client
985 macs are an interesting niche, but I fear a server is a rathole
986 working bare iron recovery for windows
987 the option for inc/diff backups not reset on fileset revision
988 a) use both change and inode update time against base time
989 b) do the full catalog check (expensive but accurate)
990 sizing guide (how much system is needed to back up N systems/files)
991 consultants on using bacula in building a disaster recovery system
993 or how to get at fancy things that one could do with bacula
994 logwatch code for bacula logs (or similar)
995 linux distro inclusion of bacula (brings good and bad, but necessary)
996 win2k/XP server capability (icky but you asked)
997 support for Oracle database ??
999 - Look at adding SQL server and Exchange support for Windows.
1000 - Make dev->file and dev->block_num signed integers so that -1 can
1001 be an invalid value which happens with BSR.
1002 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1003 is needed to properly specify ranges.
1004 - Add progress of files/bytes to SD and FD.
1005 - Print warning message if FileId > 4 billion
1006 - do a "messages" before the first prompt in Console
1007 - Client does not show busy during Estimate command.
1008 - Implement Console mtx commands.
1009 - Implement a Mount Command and an Unmount Command where
1010 the users could specify a system command to be performed
1011 to do the mount, after which Bacula could attempt to
1012 read the device. This is for Removeable media such as a CDROM.
1013 - Most likely, this mount command would be invoked explicitly
1014 by the user using the current Console "mount" and "unmount"
1015 commands -- the Storage Daemon would do the right thing
1016 depending on the exact nature of the device.
1017 - As with tape drives, when Bacula wanted a new removable
1018 disk mounted, it would unmount the old one, and send a message
1019 to the user, who would then use "mount" as described above
1020 once he had actually inserted the disk.
1021 - Implement dump/print label to UA
1022 - Spool to disk only when the tape is full, then when a tape is hung move
1024 - bextract is sending everything to the log file ****FIXME****
1025 - Allow multiple Storage specifications (or multiple names on
1026 a single Storage specification) in the Job record. Thus a job
1027 can be backed up to a number of storage devices.
1028 - Implement some way for the File daemon to contact the Director
1029 to start a job or pass its DHCP obtained IP number.
1030 - Implement a query tape prompt/replace feature for a console
1031 - Copy console @ code to gnome2-console
1032 - Make AES the only encryption algorithm see
1033 http://csrc.nist.gov/CryptoToolkit/aes/). It's
1034 an officially adopted standard, has survived peer
1035 review, and provides keys up to 256 bits.
1036 - Take a careful look at SetACL http://setacl.sourceforge.net
1037 - Make tree walk routines like cd, ls, ... more user friendly
1038 by handling spaces better.
1039 - Make sure that Bacula rechecks the tape after the 20 min wait.
1040 - Set IO_NOWAIT on Bacula TCP/IP packets.
1041 - Try doing a raw partition backup and restore by mounting a
1043 - From Lars Kellers:
1044 Yes, it would allow to highly automatic the request for new tapes. If a
1045 tape is empty, bacula reads the barcodes (native or simulated), and if
1046 an unused tape is found, it runs the label command with all the
1047 necessary parameters.
1049 By the way can bacula automatically "move" an empty/purged volume say
1050 in the "short" pool to the "long" pool if this pool runs out of volume
1052 - What to do about "list files job=xxx".
1053 - Get and test MySQL 4.0
1054 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1055 file descriptor leak in Bacula.
1056 - Implement WrapCounters in Counters.
1057 - Add heartbeat from FD to SD if hb interval expires.
1058 - Can we dynamically change FileSets?
1059 - If pool specified to label command and Label Format is specified,
1060 automatically generate the Volume name.
1061 - Why can't SQL do the filename sort for restore?
1062 - Add ExhautiveRestoreSearch
1063 - Look at the possibility of loading only the necessary
1064 data into the restore tree (i.e. do it one directory at a
1065 time as the user walks through the tree).
1066 - Possibly use the hash code if the user selects all for a restore command.
1067 - Fix "restore all" to bypass building the tree.
1068 - Prohibit backing up archive device (findlib/find_one.c:128)
1069 - Implement Release Device in the Job resource to unmount a drive.
1070 - Implement Acquire Device in the Job resource to mount a drive,
1071 be sure this works with admin jobs so that the user can get
1072 prompted to insert the correct tape. Possibly some way to say to
1073 run the job but don't save the files.
1074 - Make things like list where a file is saved case independent for
1077 - Use autochanger to handle multiple devices.
1078 - On Windows with very long path names, it may be impossible to create
1079 a file (and thus restore it) because the total length is too long.
1080 We must cd into the directory then create the file without the
1082 - Implement a Recycle command
1083 - Test a second language e.g. french.
1084 - Start working on Base jobs.
1085 - Implement UnsavedFiles DB record.
1086 - From Phil Stracchino:
1087 It would probably be a per-client option, and would be called
1088 something like, say, "Automatically purge obsoleted jobs". What it
1089 would do is, when you successfully complete a Differential backup of a
1090 client, it would automatically purge all Incremental backups for that
1091 client that are rendered redundant by that Differential. Likewise,
1092 when a Full backup on a client completed, it would automatically purge
1093 all Differential and Incremental jobs obsoleted by that Full backup.
1094 This would let people minimize the number of tapes they're keeping on
1095 hand without having to master the art of retention times.
1096 - When doing a Backup send all attributes back to the Director, who
1097 would then figure out what files have been deleted.
1098 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1099 explicit permission to do so. It should also mark the tape in error
1100 if there is an error.
1101 - Cancel waiting for Client connect in SD if FD goes away.
1103 - Implement timeout in response() when it should come quickly.
1104 - Implement a Slot priority (loaded/not loaded).
1105 - Implement "vacation" Incremental only saves.
1106 - Implement create "FileSet"?
1107 - Add prefixlinks to where or not where absolute links to FD.
1108 - Issue message to mount a new tape before the rewind.
1109 - Simplified client job initiation for portables.
1110 - If SD cannot open a drive, make it periodically retry.
1111 - Add more of the config info to the tape label.
1113 - If tape is marked read-only, then try opening it read-only rather than
1114 failing, and remember that it cannot be written.
1115 - Refine SD waiting output:
1116 Device is being positioned
1117 > Device is being positioned for append
1118 > Device is being positioned to file x
1120 - Figure out some way to estimate output size and to avoid splitting
1121 a backup across two Volumes -- this could be useful for writing CDROMs
1122 where you really prefer not to have it split -- not serious.
1123 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1124 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1125 actual data on the Volume and compare it.
1126 - Implement Bacula plugins -- design API
1127 - Make bcopy read through bad tape records.
1128 - Program files (i.e. execute a program to read/write files).
1129 Pass read date of last backup, size of file last time.
1130 - Add Signature type to File DB record.
1131 - CD into subdirectory when open()ing files for backup to
1132 speed up things. Test with testfind().
1133 - Priority job to go to top of list.
1134 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1135 - Implement some way for the Console to dynamically create a job.
1136 - Solaris -I on tar for include list
1137 - Need a verbose mode in restore, perhaps to bsr.
1138 - bscan without -v is too quiet -- perhaps show jobs.
1139 - Add code to reject whole blocks if not wanted on restore.

1239 - Director needs a time after which the report status is sent
1240 anyway -- or better yet, a retry time for the job.
1241 - Don't reschedule a job if previous incarnation is still running.
1242 - Some way to automatically backup everything is needed????
1243 - Need a structure for pending actions:
1245 - termination status (part of buffered msgs?)
1247 Read, Write, Clean, Delete
1248 - Login to Bacula; Bacula users with different permissions:
1249 owner, group, user, quotas
1250 - Store info on each file system type (probably in the job header on tape.
1251 This could be the output of df; or perhaps some sort of /etc/mtab record.

1254 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1255 To: <kern@sibbald.com>
1256 Subject: RE: [Bacula-users] future large programming jobs
1257 Date: Thu, 26 Feb 2004 11:34:54 -0600
1259 I noticed the subject thread and thought I would offer the following
1260 merely as sources of ideas, i.e. something to think about, not even as
1261 strong as a request. In my former life (before retiring) I often
1262 dealt with backups and storage management issues/products as a
1263 developer and as a consultant. I am currently migrating my personal
1264 network from amanda to bacula specifically because of the ability to
1265 cross media boundaries during storing backups.
1266 Are you familiar with the commercial product called ADSM (I think IBM
1267 now sells it under the Tivoli label)? It has a couple of interesting
1268 ideas that may apply to the following topics.
1270 1. Migration: Consider that when you need to restore a system, there
1271 may be pressure to hurry. If all the information for a single client
1272 can eventually end up on the same media (and in chronological order),
1273 the restore is facillitated by not having to search past information
1274 from other clients. ADSM has the concept of "client affinity" that
1275 may be associated with it's storage pools. It seems to me that this
1276 concept (as an optional feature) might fit in your architecture for
1279 ADSM also has the concept of defining one or more storage pools as
1280 "copy pools" (almost mirrors, but only in the sense of contents).
1281 These pools provide the ability to have duplicte data stored both
1282 onsite and offsite. The copy process can be scheduled to be handled
1283 by their storage manager during periods when there is no backup
1284 activity. Again, the migration process might be a place to consider
1285 implementing something like this.
1288 > It strikes me that it would be very nice to be able to do things
1290 > have the Job(s) backing up the machines run, and once they have all

1296 > mechanism described below would probably make it very easy.
1298 This is the goal. In the first step (before events), you simply
1300 the Migration to tape later.
1302 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1303 the database. Once a file (unique by path and metadata such as dates,
1304 size, ownership, etc.) is in a copy pool, no more copies are made. In
1305 other words, when you start ADSM, it begins like your concept of a
1306 base job. After that it is in the "incremental" mode. You can
1307 configure the number of "generations" of files to be retained, plus a
1308 retention date after which even old generations are purged. The
1309 database tracks the contents of media and projects the percentage of
1310 each volume that is valid. When the valid content of a volume drops
1311 below a configured percentage, the valid data are migrated to another
1312 volume and the old volume is marked as empty. Note, this requires
1313 ADSM to have an idea of the contents of a client, i.e. marking the
1314 database when an existing file was deleted, but this would solve your
1315 issue of restoring a client without restoring deleted files.
1317 This is pretty far from what bacula now does, but if you are going to
1318 rip things up for Base jobs,.....
1319 Also, the benefits of this are huge for very large shops, especially
1320 with media robots, but are a pain for shops with manual media
1324 > Base jobs sound pretty useful, but I'm not dying for them.
1326 Nobody is dying for them, but when you see what it does, you will die
1329 3. Restoring deleted files: Since I think my comments in (2) above
1330 have low probability of implementation, I'll also suggest that you
1331 could approach the issue of deleted files by a mechanism of having the
1332 fd report to the dir, a list of all files on the client for every
1333 backup job. The dir could note in the database entry for each file
1334 the date that the file was seen. Then if a restore as of date X takes
1335 place, only files that exist from before X until after X would be
1336 restored. Probably the major cost here is the extra date container in
1337 each row of the files table.
1339 Thanks for "listening". I hope some of this helps. If you want to
1340 contact me, please send me an email - I read some but not all of the
1341 mailing list traffic and might miss a reply there.
1343 Please accept my compliments for bacula. It is doing a great job for
1344 me!! I sympathize with you in the need to wrestle with excelence in
1345 execution vs. excelence in feature inclusion.
1350 ==============================
1353 - Design at hierarchial storage for Bacula. Migration and Clone.
1354 - Implement FSM (File System Modules).
1355 - Audit M_ error codes to ensure they are correct and consistent.
1356 - Add variable break characters to lex analyzer.
1357 Either a bit mask or a string of chars so that
1358 the caller can change the break characters.
1359 - Make a single T_BREAK to replace T_COMMA, etc.
1360 - Ensure that File daemon and Storage daemon can
1361 continue a save if the Director goes down (this
1362 is NOT currently the case). Must detect socket error,
1363 buffer messages for later.
1364 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1365 - Add ability to backup to two Storage devices (two SD sessions) at
1366 the same time -- e.g. onsite, offsite.
1367 - Add the ability to consolidate old backup sets (basically do a restore
1368 to tape and appropriately update the catalog). Compress Volume sets.
1369 Might need to spool via file is only one drive is available.
1370 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1371 someway to do so with every volume that has less than x% valid
1375 Migration: Move a backup from one Volume to another
1376 Clone: Copy a backup -- two Volumes
1378 Bacula Migration is based on Jobs (apparently Networker is file by file).
1380 Migration triggered by:
1384 Highwater mark (keep total size)
1389 ======================================================
1391 It is somewhat like a Full save becomes an incremental since
1392 the Base job (or jobs) plus other non-base files.
1394 - A Base backup is same as Full backup, just different type.
1395 - New BaseFiles table that contains:
1397 BaseJobId - Base JobId referenced for this FileId (needed ???)
1398 JobId - JobId currently running
1399 FileId - File not backed up, exists in Base Job
1400 FileIndex - FileIndex from Base Job.
1401 i.e. for each base file that exists but is not saved because
1402 it has not changed, the File daemon sends the JobId, BaseId,
1403 FileId, FileIndex back to the Director who creates the DB entry.
1404 - To initiate a Base save, the Director sends the FD
1405 the FileId, and full filename for each file in the Base.
1406 - When the FD finds a Base file, he requests the Director to
1407 send him the full File entry (stat packet plus MD5), or
1408 conversely, the FD sends it to the Director and the Director
1409 says yes or no. This can be quite rapid if the FileId is kept
1410 by the FD for each Base Filename.
1411 - It is probably better to have the comparison done by the FD
1412 despite the fact that the File entry must be sent across the
1414 - An alternative would be to send the FD the whole File entry
1415 from the start. The disadvantage is that it requires a lot of
1416 space. The advantage is that it requires less communications
1418 - The Job record must be updated to indicate that one or more
1420 - At end of Job, FD returns:
1421 1. Count of base files/bytes not written to tape (i.e. matches)
1422 2. Count of base file that were saved i.e. had changed.
1423 - No tape record would be written for a Base file that matches, in the
1424 same way that no tape record is written for Incremental jobs where
1425 the file is not saved because it is unchanged.
1426 - On a restore, all the Base file records must explicitly be
1427 found from the BaseFile tape. I.e. for each Full save that is marked
1428 to have one or more Base Jobs, search the BaseFile for all occurrences
1430 - An optimization might be to make the BaseFile have:
1436 This would avoid the need to explicitly fetch each File record for
1437 the Base job. The Base Job record will be fetched to get the
1438 VolSessionId and VolSessionTime.
1439 =========================================================
1442 ==========================================================
1444 For each Incremental job that is run, there may be files that
1445 were found but not saved because they were locked (this applies
1446 only to Windows). Such a system could send back to the Director
1447 a list of Unsaved files.
1449 - New UnSavedFiles table that contains:
1453 - Then in the next Incremental job, the list of Unsaved Files will be
1454 feed to the FD, who will ensure that they are explicitly chosen even
1455 if standard date/time check would not have selected them.

1500 There needs to be a table of drive # to devices somewhere - If there are
1501 multiple changers or drives there may not be a 1:1 correspondance between
1502 changer drive number and system device name - and depending on the way the
1503 drives are hooked up to scsi busses, they may not be linearly numbered
1504 from an offset point either.something like
1506 Autochanger drives = 2
1507 Autochanger drive 0 = /dev/nst1
1508 Autochanger drive 1 = /dev/nst2
1509 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1510 times, not just for multidrive changers. For a 1 drive changer, that's
1516 MTX's manpage (1.2.15):
1517 unload [<slotnum>] [ <drivenum> ]
1518 Unloads media from drive <drivenum> into slot
1519 <slotnum>. If <drivenum> is omitted, defaults to
1520 drive 0 (as do all commands). If <slotnum> is
1521 omitted, defaults to the slot that the drive was
1522 loaded from. Note that there's currently no way
1523 to say 'unload drive 1's media to the slot it
1524 came from', other than to explicitly use that
1525 slot number as the destination.AB

1563 Handling removable disks
1565 From: Karl Cunningham <karlc@keckec.com>
1567 My backups are only to hard disk these days, in removable bays. This is my
1568 idea of how a backup to hard disk would work more smoothly. Some of these
1569 things Bacula does already, but I mention them for completeness. If others
1570 have better ways to do this, I'd like to hear about it.
1572 1. Accommodate several disks, rotated similar to how tapes are. Identified
1573 by partition volume ID or perhaps by the name of a subdirectory.
1574 2. Abort & notify the admin if the wrong disk is in the bay.
1575 3. Write backups to different subdirectories for each machine to be backed
1577 4. Volumes (files) get created as needed in the proper subdirectory, one
1579 5. When a disk is recycled, remove or zero all old backup files. This is
1580 important as the disk being recycled may be close to full. This may be
1581 better done manually since the backup files for many machines may be
1582 scattered in many subdirectories.
1587 - Make sure that all do_prompt() calls in Dir check for
1588 -1 (error) and -2 (cancel) returns.
1589 - Fix foreach_jcr() to have free_jcr() inside next().
1590 jcr=jcr_walk_start();
1591 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1594 - A Volume taken from Scratch should take on the retention period
1596 - Correct doc for Maximum Changer Wait (and others) accepting only
1598 - Implement status that shows why a job is being held in reserve, or
1599 rather why none of the drives are suitable.
1600 - Implement a way to disable a drive (so you can use the second
1601 drive of an autochanger, and the first one will not be used or
1603 - Make sure Maximum Volumes is respected in Pools when adding
1604 Volumes (e.g. when pulling a Scratch volume).
1605 - Keep same dcr when switching device ...
1606 - Implement code that makes the Dir aware that a drive is an
1607 autochanger (so the user doesn't need to use the Autochanger = yes
1609 - Make catalog respect ACL.
1610 - Add recycle count to Media record.
1611 - Add initial write date to Media record.
1612 - Fix store_yesno to be store_bitmask.
