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

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

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

488 - Bug: if a job is manually scheduled to run later, it does not appear
489 in any status report and cannot be cancelled.
491 ==== Keeping track of deleted/new files ====
492 - To mark files as deleted, run essentially a Verify to disk, and
493 when a file is found missing (MarkId != JobId), then create
494 a new File record with FileIndex == -1. This could be done
495 by the FD at the same time as the backup.
497 My "trick" for keeping track of deletions is the following.
498 Assuming the user turns on this option, after all the files
499 have been backed up, but before the job has terminated, the
500 FD will make a pass through all the files and send their
501 names to the DIR (*exactly* the same as what a Verify job
502 currently does). This will probably be done at the same
503 time the files are being sent to the SD avoiding a second
504 pass. The DIR will then compare that to what is stored in
505 the catalog. Any files in the catalog but not in what the
506 FD sent will receive a catalog File entry that indicates
507 that at that point in time the file was deleted. This
508 either transmitted to the FD or simultaneously computed in
509 the FD, so that the FD can put a record on the tape that
510 indicates that the file has been deleted at this point.
511 A delete file entry could potentially be one with a FileIndex
512 of 0 or perhaps -1 (need to check if FileIndex is used for
513 some other thing as many of the Bacula fields are "overloaded"
516 During a restore, any file initially picked up by some
517 backup (Full, ...) then subsequently having a File entry
518 marked "delete" will be removed from the tree, so will not
519 be restored. If a file with the same name is later OK it
520 will be inserted in the tree -- this already happens. All
521 will be consistent except for possible changes during the
524 Since I'm on the subject, some of you may be wondering what
525 the utility of the in memory tree is if you are going to
526 restore everything (at least it comes up from time to time
527 on the list). Well, it is still *very* useful because it
528 allows only the last item found for a particular filename
529 (full path) to be entered into the tree, and thus if a file
530 is backed up 10 times, only the last copy will be restored.
531 I recently (last Friday) restored a complete directory, and
532 the Full and all the Differential and Incremental backups
533 spanned 3 Volumes. The first Volume was not even mounted
534 because all the files had been updated and hence backed up
535 since the Full backup was made. In this case, the tree
536 saved me a *lot* of time.
538 Make sure this information is stored on the tape too so
539 that it can be restored directly from the tape.
541 All the code (with the exception of formally generating and
542 saving the delete file entries) already exists in the Verify
543 Catalog command. It explicitly recognizes added/deleted files since
544 the last InitCatalog. It is more or less a "simple" matter of
545 taking that code and adapting it slightly to work for backups.
547 Comments from Martin Simmons (I think they are all covered):
548 Ok, that should cover the basics. There are few issues though:
550 - Restore will depend on the catalog. I think it is better to include the
551 extra data in the backup as well, so it can be seen by bscan and bextract.
553 - I'm not sure if it will preserve multiple hard links to the same inode. Or
554 maybe adding or removing links will cause the data to be dumped again?
556 - I'm not sure if it will handle renamed directories. Possibly it will work
557 by dumping the whole tree under a renamed directory?
559 - It remains to be seen how the backup performance of the DIR's will be
560 affected when comparing the catalog for a large filesystem.
564 How about introducing a Type = MgmtPolicy job type? That job type would
565 be responsible for scanning the Bacula environment looking for specific
566 conditions, and submitting the appropriate jobs for implementing said
570 Name = "Migration-Policy"
572 Policy Selection Job Type = Migrate
573 Scope = "<keyword> <operator> <regexp>"
574 Threshold = "<keyword> <operator> <regexp>"
575 Job Template = <template-name>
578 Where <keyword> is any legal job keyword, <operator> is a comparison
579 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
580 appropriate regexp. I could see an argument for Scope and Threshold
581 being SQL queries if we want to support full flexibility. The
582 Migration-Policy job would then get scheduled as frequently as a site
583 felt necessary (suggested default: every 15 minutes).
588 Name = "Migration-Policy"
590 Policy Selection Job Type = Migration
592 Threshold = "Migration Selection Type = LowestUtil"
593 Job Template = "MigrationTemplate"
596 would select all pools for examination and generate a job based on
597 MigrationTemplate to automatically select the volume with the lowest
598 usage and migrate it's contents to the nextpool defined for that pool.
600 This policy abstraction would be really handy for adjusting the behavior
601 of Bacula according to site-selectable criteria (one thing that pops
602 into mind is Amanda's ability to automatically adjust backup levels
603 depending on various criteria).
609 - Add Pool/Storage override regression test.
610 - Add delete JobId to regression.
611 - Add a regression test for dbcheck.
612 - New test to add bscan to four-concurrent-jobs regression,
613 i.e. after the four-concurrent jobs zap the
614 database as is done in the bscan-test, then use bscan to
615 restore the database, do a restore and compare with the
617 - Add restore of specific JobId to regression (item 3

619 - Add IPv6 to regression
620 - Add database test to regression. Test each function like delete,

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

636 === From Carsten Menke <bootsy52@gmx.net>
638 Following is a list of what I think in the situations where I'm faced with,
639 could be a usefull enhancement to bacula, which I'm certain other users will
640 benefit from as well.
642 1. NextJob/NextJobs Directive within a Job Resource in the form of
643 NextJobs = job1,job2.
646 I currently solved the problem with running multiple jobs each after each
647 by setting the Max Wait Time for a job to 8 hours, and give
648 the jobs different Priorities. However, there scenarios where
649 1 Job is directly depending on another job, so if the former job fails,
650 the job after it needn't to be run
651 while maybe other jobs should run despite of that
654 A Backup Job and a Verify job, if the backup job fails there is no need to run
655 the verify job, as the backup job already failed. However, one may like
656 to backup the Catalog to disk despite of that the main backup job failed.
659 I see that this is related to the Event Handlers which are on the ToDo
660 list, also it is maybe a good idea to check for the return value and
661 execute different actions based on the return value
664 3. offline capability to bconsole
667 Currently I use a script which I execute within the last Job via the
668 RunAfterJob Directive, to release and eject the tape.
669 So I have to call bconsole "release=Storage-Name" and afterwards
670 mt -f /dev/nst0 eject to get the tape out.
672 If I have multiple Storage Devices, than these may not be /dev/nst0 and
673 I have to modify the script or call it with parameters etc.
674 This would actually not be needed, as everything is already defined
675 in bacula-sd.conf and if I can invoke bconsole with the
676 storage name via $1 in the script than I'm done and information is
679 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
683 For the reason mentioned in 3. to have the ability to call a
684 script with /scripts/foobar %s and in the script use $1
685 to pass the Storage Name to bconsole
687 5. Setting Volume State within a Job Resource
690 Instead of using "Maximum Volume Jobs" in the Pool Resource,
691 I would have the possibilty to define
692 in a Job Resource that after this certain job is run, the Volume State
693 should be set to "Volume State = Used", this give more flexibility (IMHO).
695 6. Localization of Bacula Messages
698 Unfortunatley many,many people I work with don't speak english very well.
699 So if at least the Reporting messages would be localized then they
700 would understand that they have to change the tape,etc. etc.
702 I volunteer to do the german translations, and if I can convince my wife also
703 french and Morre (western african language).
705 7. OK, this is evil, probably bound to security risks and maybe not possible
706 due to the design of bacula.
708 Implementation of Backtics ( `command` ) for shell comand execution to
709 the "Label Format" Directive.
713 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
714 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
715 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
716 the localized name for the day of the week appended to the
717 format string. Then I have the tape labeled automatically with weekday
718 name in the correct language.
720 - Yes, that is surely the case. I probably should turn those into Warning
721 errors. In addition, you just made me think that it might not be bad to
722 add an option to check the file size after backing up the file and
723 report if it changes. This would be done as an option because it would
726 Kern, good idea. If you do do that, mention in the output: file
727 shrunk, or file expanded, just to make it obvious to the user
728 (without having to the refer to file size), just how the file size
731 Would this option be for all file, or just one file? Or a fileset?
732 - Make output from status use html table tags for nicely
733 presenting in a browser.
734 - Can one write tapes faster with 8192 byte block sizes?
735 - Document security problems with the same password for everyone in
736 rpm and Win32 releases.
737 - Browse generations of files.
738 - I've seen an error when my catalog's File table fills up. I
739 then have to recreate the File table with a larger maximum row
740 size. Relevant information is at
741 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
742 "Installing and Configuring MySQL" chapter should talk a bit
743 about this potential problem, and recommend a solution.
744 - For Solaris must use POSIX awk.
745 - Want speed of writing to tape while despooling.
746 - Supported autochanger:
754 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
755 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
756 - Add regex from http://www.pcre.org to Bacula for Win32.
757 - Use only shell tools no make in CDROM package.
758 - Include within include does it work?
759 - Implement a Pool of type Cleaning?
760 - Implement VolReadTime and VolWriteTime in SD
761 - Modify Backing up Your Database to include a bootstrap file.
762 - Think about making certain database errors fatal.
763 - Look at correcting the time jump in the scheduler for daylight
764 savings time changes.
765 - Add a "real" timer to network connections.
766 - Promote to Full = Time period
767 - Check dates entered by user for correctness (month/day/... ranges)
768 - Compress restore Volume listing by date and first file.
769 - Look at patches/bacula_db.b2z postgresql that loops during restore.
771 - Perhaps add read/write programs and/or plugins to FileSets.
772 - How to handle backing up portables ...
773 - Add some sort of guaranteed Interval for upgrading jobs.
774 - Can we write the state file after every job terminates? On Win32
775 the system crashes and the state file is not updated.
778 Documentation to do: (any release a little bit at a time)
779 - Doc to do unmount before removing magazine.
780 - Alternative to static linking "ldd prog" save all binaries listed,
781 restore them and point LD_LIBRARY_PATH to them.
782 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
783 - Document query file format.
784 - Add more documentation for bsr files.
785 - Document problems with Verify and pruning.
786 - Document how to use multiple databases.
787 - VXA drives have a "cleaning required"
788 indicator, but Exabyte recommends preventive cleaning after every 75
791 In this context, it should be noted that Exabyte has a command-line
792 vxatool utility available for free download. (The current version is
793 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
794 test the drive, unload tapes, change drive settings, flash new firmware,
796 Of particular interest in this context is that vxatool <device> -i will
797 report, among other details, the time since last cleaning in tape motion
798 minutes. This information can be retrieved (and settings changed, for
799 that matter) through the generic-SCSI device even when Bacula has the
800 regular tape device locked. (Needless to say, I don't recommend
801 changing tape settings while a job is running.)
802 - Lookup HP cleaning recommendations.
803 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
804 - Document doing table repair
807 ===================================
808 - Add macro expansions in JobDefs.
809 Run Before Job = "SomeFile %{Level} %{Client}"
810 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
811 - Use non-blocking network I/O but if no data is available, use
813 - Use gather write() for network I/O.
814 - Autorestart on crash.
815 - Add bandwidth limiting.
816 - Add acks every once and a while from the SD to keep
817 the line from timing out.
818 - When an error in input occurs and conio beeps, you can back
819 up through the prompt.
820 - Detect fixed tape block mode during positioning by looking at
821 block numbers in btape "test". Possibly adjust in Bacula.
822 - Fix list volumes to output volume retention in some other
823 units, perhaps via a directive.
824 - If opening a tape in read/write mode fails attempt to open
825 it in read-only mode, and mark the tape for read only.
826 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
827 with multiple priorities.
828 - If you use restore replace=never, the directory attributes for
829 non-existent directories will not be restored properly.
831 - see lzma401.zip in others directory for new compression
833 - Minimal autochanger handling in Bacula and in btape.
834 - Look into how tar does not save sockets and the possiblity of
835 not saving them in Bacula (Martin Simmons reported this).
836 - Fix restore jobs so that multiple jobs can run if they
837 are not using the same tape(s).
838 - Allow the user to select JobType for manual pruning/purging.
839 - bscan does not put first of two volumes back with all info in
841 - Implement the FreeBSD nodump flag in chflags.
842 - Figure out how to make named console messages go only to that
843 console and to the non-restricted console (new console class?).
844 - Make restricted console prompt for password if *ask* is set or
845 perhaps if password is undefined.
846 - Implement "from ISO-date/time every x hours/days/weeks/months" in
849 ==== from Marc Schoechlin
850 - the help-command should be more verbose
851 (it should explain the paramters of the different
853 -> its time-comsuming to consult the manual anytime
854 you need a special parameter
855 -> maybe its more easy to maintain this, if the
856 descriptions of that commands are outsourced to
858 - the cd-command should allow complete paths
859 i.e. cd /foo/bar/foo/bar
860 -> if a customer mails me the path to a certain file,
861 its faster to enter the specified directory
862 - if the password is not configured in bconsole.conf
863 you should be asked for it.
864 -> sometimes you like to do restore on a customer-machine
865 which shouldnt know the password for bacula.
866 -> adding the password to the file favours admins
867 to forget to remove the password after usage
869 the protection of that file is less important
870 - long-listed-output of commands should be scrollable
871 like the unix more/less-command does
872 -> if someone runs 200 and more machines, the lists could
873 be a little long and complex
874 - command-output should be shown column by column
875 to reduce scrolling and to increase clarity
877 - lsmark should list the selected files with full
879 - wildcards for selecting and file and directories would be nice
880 - any actions should be interuptable with STRG+C
881 - command-expansion would be pretty cool
883 - When the replace Never option is set, new directory permissions
884 are not restored. See bug 213. To fix this requires creating a
885 list of newly restored directories so that those directory
886 permissions *can* be restored.
887 - Compaction of Disk space by "migrating" Volumes that have pruned
888 Jobs (what criteria? size, #jobs, time).
889 - Add prune all command
890 - Document fact that purge can destroy a part of a restore by purging
891 one volume while others remain valid -- perhaps mark Jobs.
892 - Add multiple-media-types.txt
893 - look at mxt-changer.html
894 - Make ? do a help command (no return needed).
895 - Implement restore directory.
896 - Document streams and how to implement them.
897 - Try not to re-backup a file if a new hard link is added.
898 - Add feature to backup hard links only, but not the data.
899 - Fix stream handling to be simpler.
900 - Add Priority and Bootstrap to Run a Job.
901 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
903 - Remove View FileSet button from Run a Job dialog.
904 - Handle prompt for restore job at end of Restore command.
905 - Add display of total selected files to Restore window.
906 - Add tree pane to left of window.
907 - Add progress meter.
908 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
909 - Document writing to a CD/DVD with Bacula.
910 - Add a "base" package to the window installer for pthreadsVCE.dll
911 which is needed by all packages.
912 - Add message to user to check for fixed block size when the forward
913 space test fails in btape.
914 - When unmarking a directory check if all files below are unmarked and
915 then remove the + flag -- in the restore tree.
916 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
917 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
918 - Revisit the question of multiple Volumes (disk) on a single device.
919 - Add a block copy option to bcopy.
920 - Investigate adding Mac Resource Forks.
921 - Finish work on Gnome restore GUI.
922 - Fix "llist jobid=xx" where no fileset or client exists.
923 - For each job type (Admin, Restore, ...) require only the really necessary
924 fields.- Pass Director resource name as an option to the Console.
925 - Add a "batch" mode to the Console (no unsolicited queries, ...).
926 - Add a .list all files in the restore tree (probably also a list all files)
927 Do both a long and short form.
928 - Allow browsing the catalog to see all versions of a file (with
929 stat data on each file).
930 - Restore attributes of directory if replace=never set but directory
932 - Use SHA1 on authentication if possible.
933 - See comtest-xxx.zip for Windows code to talk to USB.
934 - Add John's appended files:
935 Appended = { /files/server/logs/http/*log }
936 and such files would be treated as follows.On a FULL backup, they would
937 be backed up like any other file.On an INCREMENTAL backup, where a
938 previous INCREMENTAL or FULL was already in thecatalogue and the length
939 of the file wasgreater than the length of the last backup, only thedata
940 added since the last backup will be dumped.On an INCREMENTAL backup, if
941 the length of the file is less than thelength of the file with the same
942 name last backed up, the completefile is dumped.On Windows systems, with
943 creation date of files, we can be evensmarter about this and not count
944 entirely upon the length.On a restore, the full and all incrementals
945 since it will beapplied in sequence to restore the file.
946 - Check new HAVE_WIN32 open bits.
947 - Check if the tape has moved before writing.
948 - Handling removable disks -- see below:
949 - Keep track of tape use time, and report when cleaning is necessary.
950 - Add FromClient and ToClient keywords on restore command (or
951 BackupClient RestoreClient).
952 - Implement a JobSet, which groups any number of jobs. If the
953 JobSet is started, all the jobs are started together.
954 Allow Pool, Level, and Schedule overrides.
955 - Enhance cancel to timeout BSOCK packets after a specific delay.
956 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
957 ua_status.!!! Thanks to Alan Brown for this tip.
958 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
959 correctly for multiple simultaneous jobs.
960 - Correct code so that FileSet MD5 is calculated for < and | filename
962 - Implement the Media record flag that indicates that the Volume does disk
964 - Implement VolAddr, which is used when Volume is addressed like a disk,
965 and form it from VolFile and VolBlock.
966 - Make multiple restore jobs for multiple media types specifying
967 the proper storage type.
968 - Fix fast block rejection (stored/read_record.c:118). It passes a null
969 pointer (rec) to try_repositioning().
970 - Look at extracting Win data from BackupRead.
971 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
972 which would take precidence over the Catalog "JobRetention".
973 - Implement Label Format in Add and Label console commands.
974 - Possibly up network buffers to 65K. Put on variable.
975 - Put email tape request delays on one or more variables. User wants
976 to cancel the job after a certain time interval. Maximum Mount Wait?
977 - Job, Client, Device, Pool, or Volume?
978 Is it possible to make this a directive which is *optional* in multiple
979 resources, like Level? If so, I think I'd make it an optional directive
980 in Job, Client, and Pool, with precedence such that Job overrides Client
981 which in turn overrides Pool.
983 - New Storage specifications:
984 - Want to write to multiple storage devices simultaneously
985 - Want to write to multiple storage devices sequentially (in one job)
986 - Want to read/write simultaneously
987 - Key is MediaType -- it must match
989 Passed to SD as a sort of BSR record called Storage Specification
993 MediaType -> Next MediaType
995 Device -> Next Device
997 Allow multiple Storage specifications
1005 Allow Multiple Pool specifications (note, Pool currently
1007 Allow Multiple MediaType specifications in Dir conf
1008 Allow Multiple Device specifications in Dir conf
1009 Perhaps keep this in a single SSR
1010 Tie a Volume to a specific device by using a MediaType that
1011 is contained in only one device.
1012 In SD allow Device to have Multiple MediaTypes
1014 - Ideas from Jerry Scharf:
1015 First let's point out some big pluses that bacula has for this
1017 more importantly it's active. Thank you so much for that
1018 even more important, it's not flaky
1019 it has an open access catalog, opening many possibilities
1020 it's pushing toward heterogeneous systems capability
1022 Macintosh file client
1023 macs are an interesting niche, but I fear a server is a rathole
1024 working bare iron recovery for windows
1025 the option for inc/diff backups not reset on fileset revision
1026 a) use both change and inode update time against base time
1027 b) do the full catalog check (expensive but accurate)
1028 sizing guide (how much system is needed to back up N systems/files)
1029 consultants on using bacula in building a disaster recovery system
1030 an integration guide
1031 or how to get at fancy things that one could do with bacula
1032 logwatch code for bacula logs (or similar)
1033 linux distro inclusion of bacula (brings good and bad, but necessary)
1034 win2k/XP server capability (icky but you asked)
1035 support for Oracle database ??
1037 - Look at adding SQL server and Exchange support for Windows.
1038 - Make dev->file and dev->block_num signed integers so that -1 can
1039 be an invalid value which happens with BSR.
1040 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1041 is needed to properly specify ranges.
1042 - Add progress of files/bytes to SD and FD.
1043 - Print warning message if FileId > 4 billion
1044 - do a "messages" before the first prompt in Console
1045 - Client does not show busy during Estimate command.
1046 - Implement Console mtx commands.
1047 - Implement a Mount Command and an Unmount Command where
1048 the users could specify a system command to be performed
1049 to do the mount, after which Bacula could attempt to
1050 read the device. This is for Removeable media such as a CDROM.
1051 - Most likely, this mount command would be invoked explicitly
1052 by the user using the current Console "mount" and "unmount"
1053 commands -- the Storage Daemon would do the right thing
1054 depending on the exact nature of the device.
1055 - As with tape drives, when Bacula wanted a new removable
1056 disk mounted, it would unmount the old one, and send a message
1057 to the user, who would then use "mount" as described above
1058 once he had actually inserted the disk.
1059 - Implement dump/print label to UA
1060 - Spool to disk only when the tape is full, then when a tape is hung move
1062 - bextract is sending everything to the log file ****FIXME****
1063 - Allow multiple Storage specifications (or multiple names on
1064 a single Storage specification) in the Job record. Thus a job
1065 can be backed up to a number of storage devices.
1066 - Implement some way for the File daemon to contact the Director
1067 to start a job or pass its DHCP obtained IP number.
1068 - Implement a query tape prompt/replace feature for a console
1069 - Copy console @ code to gnome2-console
1070 - Make AES the only encryption algorithm see
1071 http://csrc.nist.gov/CryptoToolkit/aes/). It's
1072 an officially adopted standard, has survived peer
1073 review, and provides keys up to 256 bits.
1074 - Take a careful look at SetACL http://setacl.sourceforge.net
1075 - Make tree walk routines like cd, ls, ... more user friendly
1076 by handling spaces better.
1077 - Make sure that Bacula rechecks the tape after the 20 min wait.
1078 - Set IO_NOWAIT on Bacula TCP/IP packets.
1079 - Try doing a raw partition backup and restore by mounting a
1081 - From Lars Kellers:
1082 Yes, it would allow to highly automatic the request for new tapes. If a
1083 tape is empty, bacula reads the barcodes (native or simulated), and if
1084 an unused tape is found, it runs the label command with all the
1085 necessary parameters.
1087 By the way can bacula automatically "move" an empty/purged volume say
1088 in the "short" pool to the "long" pool if this pool runs out of volume
1090 - What to do about "list files job=xxx".
1091 - Get and test MySQL 4.0
1092 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1093 file descriptor leak in Bacula.
1094 - Implement WrapCounters in Counters.
1095 - Add heartbeat from FD to SD if hb interval expires.
1096 - Can we dynamically change FileSets?
1097 - If pool specified to label command and Label Format is specified,
1098 automatically generate the Volume name.
1099 - Why can't SQL do the filename sort for restore?
1100 - Add ExhautiveRestoreSearch
1101 - Look at the possibility of loading only the necessary
1102 data into the restore tree (i.e. do it one directory at a
1103 time as the user walks through the tree).
1104 - Possibly use the hash code if the user selects all for a restore command.
1105 - Fix "restore all" to bypass building the tree.
1106 - Prohibit backing up archive device (findlib/find_one.c:128)
1107 - Implement Release Device in the Job resource to unmount a drive.
1108 - Implement Acquire Device in the Job resource to mount a drive,
1109 be sure this works with admin jobs so that the user can get
1110 prompted to insert the correct tape. Possibly some way to say to
1111 run the job but don't save the files.
1112 - Make things like list where a file is saved case independent for
1115 - Use autochanger to handle multiple devices.
1116 - On Windows with very long path names, it may be impossible to create
1117 a file (and thus restore it) because the total length is too long.
1118 We must cd into the directory then create the file without the
1120 - Implement a Recycle command
1121 - Test a second language e.g. french.
1122 - Start working on Base jobs.
1123 - Implement UnsavedFiles DB record.
1124 - From Phil Stracchino:
1125 It would probably be a per-client option, and would be called
1126 something like, say, "Automatically purge obsoleted jobs". What it
1127 would do is, when you successfully complete a Differential backup of a
1128 client, it would automatically purge all Incremental backups for that
1129 client that are rendered redundant by that Differential. Likewise,
1130 when a Full backup on a client completed, it would automatically purge
1131 all Differential and Incremental jobs obsoleted by that Full backup.
1132 This would let people minimize the number of tapes they're keeping on
1133 hand without having to master the art of retention times.
1134 - When doing a Backup send all attributes back to the Director, who
1135 would then figure out what files have been deleted.
1136 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1137 explicit permission to do so. It should also mark the tape in error
1138 if there is an error.
1139 - Cancel waiting for Client connect in SD if FD goes away.
1141 - Implement timeout in response() when it should come quickly.
1142 - Implement a Slot priority (loaded/not loaded).
1143 - Implement "vacation" Incremental only saves.
1144 - Implement create "FileSet"?
1145 - Add prefixlinks to where or not where absolute links to FD.
1146 - Issue message to mount a new tape before the rewind.
1147 - Simplified client job initiation for portables.
1148 - If SD cannot open a drive, make it periodically retry.
1149 - Add more of the config info to the tape label.
1151 - If tape is marked read-only, then try opening it read-only rather than
1152 failing, and remember that it cannot be written.
1153 - Refine SD waiting output:
1154 Device is being positioned
1155 > Device is being positioned for append
1156 > Device is being positioned to file x
1158 - Figure out some way to estimate output size and to avoid splitting
1159 a backup across two Volumes -- this could be useful for writing CDROMs
1160 where you really prefer not to have it split -- not serious.
1161 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1162 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1163 actual data on the Volume and compare it.

1278 anyway -- or better yet, a retry time for the job.
1279 - Don't reschedule a job if previous incarnation is still running.
1280 - Some way to automatically backup everything is needed????
1281 - Need a structure for pending actions:
1283 - termination status (part of buffered msgs?)
1285 Read, Write, Clean, Delete
1286 - Login to Bacula; Bacula users with different permissions:
1287 owner, group, user, quotas
1288 - Store info on each file system type (probably in the job header on tape.
1289 This could be the output of df; or perhaps some sort of /etc/mtab record.
1291 ========= ideas ===============
1292 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1293 To: <kern@sibbald.com>
1294 Subject: RE: [Bacula-users] future large programming jobs
1295 Date: Thu, 26 Feb 2004 11:34:54 -0600
1297 I noticed the subject thread and thought I would offer the following
1298 merely as sources of ideas, i.e. something to think about, not even as
1299 strong as a request. In my former life (before retiring) I often
1300 dealt with backups and storage management issues/products as a
1301 developer and as a consultant. I am currently migrating my personal
1302 network from amanda to bacula specifically because of the ability to
1303 cross media boundaries during storing backups.
1304 Are you familiar with the commercial product called ADSM (I think IBM
1305 now sells it under the Tivoli label)? It has a couple of interesting
1306 ideas that may apply to the following topics.
1308 1. Migration: Consider that when you need to restore a system, there
1309 may be pressure to hurry. If all the information for a single client
1310 can eventually end up on the same media (and in chronological order),
1311 the restore is facillitated by not having to search past information
1312 from other clients. ADSM has the concept of "client affinity" that
1313 may be associated with it's storage pools. It seems to me that this
1314 concept (as an optional feature) might fit in your architecture for
1317 ADSM also has the concept of defining one or more storage pools as
1318 "copy pools" (almost mirrors, but only in the sense of contents).
1319 These pools provide the ability to have duplicte data stored both
1320 onsite and offsite. The copy process can be scheduled to be handled
1321 by their storage manager during periods when there is no backup
1322 activity. Again, the migration process might be a place to consider
1323 implementing something like this.
1326 > It strikes me that it would be very nice to be able to do things
1328 > have the Job(s) backing up the machines run, and once they have all

1334 > mechanism described below would probably make it very easy.
1336 This is the goal. In the first step (before events), you simply
1338 the Migration to tape later.
1340 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1341 the database. Once a file (unique by path and metadata such as dates,
1342 size, ownership, etc.) is in a copy pool, no more copies are made. In
1343 other words, when you start ADSM, it begins like your concept of a
1344 base job. After that it is in the "incremental" mode. You can
1345 configure the number of "generations" of files to be retained, plus a
1346 retention date after which even old generations are purged. The
1347 database tracks the contents of media and projects the percentage of
1348 each volume that is valid. When the valid content of a volume drops
1349 below a configured percentage, the valid data are migrated to another
1350 volume and the old volume is marked as empty. Note, this requires
1351 ADSM to have an idea of the contents of a client, i.e. marking the
1352 database when an existing file was deleted, but this would solve your
1353 issue of restoring a client without restoring deleted files.
1355 This is pretty far from what bacula now does, but if you are going to
1356 rip things up for Base jobs,.....
1357 Also, the benefits of this are huge for very large shops, especially
1358 with media robots, but are a pain for shops with manual media
1362 > Base jobs sound pretty useful, but I'm not dying for them.
1364 Nobody is dying for them, but when you see what it does, you will die
1367 3. Restoring deleted files: Since I think my comments in (2) above
1368 have low probability of implementation, I'll also suggest that you
1369 could approach the issue of deleted files by a mechanism of having the
1370 fd report to the dir, a list of all files on the client for every
1371 backup job. The dir could note in the database entry for each file
1372 the date that the file was seen. Then if a restore as of date X takes
1373 place, only files that exist from before X until after X would be
1374 restored. Probably the major cost here is the extra date container in
1375 each row of the files table.
1377 Thanks for "listening". I hope some of this helps. If you want to
1378 contact me, please send me an email - I read some but not all of the
1379 mailing list traffic and might miss a reply there.
1381 Please accept my compliments for bacula. It is doing a great job for
1382 me!! I sympathize with you in the need to wrestle with excelence in
1383 execution vs. excelence in feature inclusion.
1388 ==============================
1391 - Design at hierarchial storage for Bacula. Migration and Clone.
1392 - Implement FSM (File System Modules).
1393 - Audit M_ error codes to ensure they are correct and consistent.
1394 - Add variable break characters to lex analyzer.
1395 Either a bit mask or a string of chars so that
1396 the caller can change the break characters.
1397 - Make a single T_BREAK to replace T_COMMA, etc.
1398 - Ensure that File daemon and Storage daemon can
1399 continue a save if the Director goes down (this
1400 is NOT currently the case). Must detect socket error,
1401 buffer messages for later.
1402 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1403 - Add ability to backup to two Storage devices (two SD sessions) at
1404 the same time -- e.g. onsite, offsite.
1405 - Add the ability to consolidate old backup sets (basically do a restore
1406 to tape and appropriately update the catalog). Compress Volume sets.
1407 Might need to spool via file is only one drive is available.
1408 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1409 someway to do so with every volume that has less than x% valid
1413 Migration: Move a backup from one Volume to another
1414 Clone: Copy a backup -- two Volumes
1416 Bacula Migration is based on Jobs (apparently Networker is file by file).
1418 Migration triggered by:
1422 Highwater mark (keep total size)
1427 ======================================================
1429 It is somewhat like a Full save becomes an incremental since
1430 the Base job (or jobs) plus other non-base files.
1432 - A Base backup is same as Full backup, just different type.
1433 - New BaseFiles table that contains:
1435 BaseJobId - Base JobId referenced for this FileId (needed ???)
1436 JobId - JobId currently running
1437 FileId - File not backed up, exists in Base Job
1438 FileIndex - FileIndex from Base Job.
1439 i.e. for each base file that exists but is not saved because
1440 it has not changed, the File daemon sends the JobId, BaseId,
1441 FileId, FileIndex back to the Director who creates the DB entry.
1442 - To initiate a Base save, the Director sends the FD
1443 the FileId, and full filename for each file in the Base.
1444 - When the FD finds a Base file, he requests the Director to
1445 send him the full File entry (stat packet plus MD5), or
1446 conversely, the FD sends it to the Director and the Director
1447 says yes or no. This can be quite rapid if the FileId is kept
1448 by the FD for each Base Filename.
1449 - It is probably better to have the comparison done by the FD
1450 despite the fact that the File entry must be sent across the
1452 - An alternative would be to send the FD the whole File entry
1453 from the start. The disadvantage is that it requires a lot of
1454 space. The advantage is that it requires less communications
1456 - The Job record must be updated to indicate that one or more
1458 - At end of Job, FD returns:
1459 1. Count of base files/bytes not written to tape (i.e. matches)
1460 2. Count of base file that were saved i.e. had changed.
1461 - No tape record would be written for a Base file that matches, in the
1462 same way that no tape record is written for Incremental jobs where
1463 the file is not saved because it is unchanged.
1464 - On a restore, all the Base file records must explicitly be
1465 found from the BaseFile tape. I.e. for each Full save that is marked
1466 to have one or more Base Jobs, search the BaseFile for all occurrences
1468 - An optimization might be to make the BaseFile have:
1474 This would avoid the need to explicitly fetch each File record for
1475 the Base job. The Base Job record will be fetched to get the
1476 VolSessionId and VolSessionTime.
1477 =========================================================
1480 ==========================================================
1482 For each Incremental job that is run, there may be files that
1483 were found but not saved because they were locked (this applies
1484 only to Windows). Such a system could send back to the Director
1485 a list of Unsaved files.
1487 - New UnSavedFiles table that contains:
1491 - Then in the next Incremental job, the list of Unsaved Files will be
1492 feed to the FD, who will ensure that they are explicitly chosen even
1493 if standard date/time check would not have selected them.
1494 =============================================================

1535 (just to verify it remembers where it came from, however it can be

1538 There needs to be a table of drive # to devices somewhere - If there are
1539 multiple changers or drives there may not be a 1:1 correspondance between
1540 changer drive number and system device name - and depending on the way the
1541 drives are hooked up to scsi busses, they may not be linearly numbered
1542 from an offset point either.something like
1544 Autochanger drives = 2
1545 Autochanger drive 0 = /dev/nst1
1546 Autochanger drive 1 = /dev/nst2
1547 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1548 times, not just for multidrive changers. For a 1 drive changer, that's
1554 MTX's manpage (1.2.15):
1555 unload [<slotnum>] [ <drivenum> ]
1556 Unloads media from drive <drivenum> into slot
1557 <slotnum>. If <drivenum> is omitted, defaults to
1558 drive 0 (as do all commands). If <slotnum> is
1559 omitted, defaults to the slot that the drive was
1560 loaded from. Note that there's currently no way
1561 to say 'unload drive 1's media to the slot it
1562 came from', other than to explicitly use that
1563 slot number as the destination.AB

1601 Handling removable disks
1603 From: Karl Cunningham <karlc@keckec.com>
1605 My backups are only to hard disk these days, in removable bays. This is my
1606 idea of how a backup to hard disk would work more smoothly. Some of these
1607 things Bacula does already, but I mention them for completeness. If others
1608 have better ways to do this, I'd like to hear about it.
1610 1. Accommodate several disks, rotated similar to how tapes are. Identified
1611 by partition volume ID or perhaps by the name of a subdirectory.
1612 2. Abort & notify the admin if the wrong disk is in the bay.
1613 3. Write backups to different subdirectories for each machine to be backed
1615 4. Volumes (files) get created as needed in the proper subdirectory, one
1617 5. When a disk is recycled, remove or zero all old backup files. This is
1618 important as the disk being recycled may be close to full. This may be
1619 better done manually since the backup files for many machines may be
1620 scattered in many subdirectories.
1625 - Make sure that all do_prompt() calls in Dir check for
1626 -1 (error) and -2 (cancel) returns.
1627 - Fix foreach_jcr() to have free_jcr() inside next().
1628 jcr=jcr_walk_start();
1629 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1632 - A Volume taken from Scratch should take on the retention period
1634 - Correct doc for Maximum Changer Wait (and others) accepting only
1636 - Implement status that shows why a job is being held in reserve, or
1637 rather why none of the drives are suitable.
1638 - Implement a way to disable a drive (so you can use the second
1639 drive of an autochanger, and the first one will not be used or
1641 - Make sure Maximum Volumes is respected in Pools when adding
1642 Volumes (e.g. when pulling a Scratch volume).
1643 - Keep same dcr when switching device ...
1644 - Implement code that makes the Dir aware that a drive is an
1645 autochanger (so the user doesn't need to use the Autochanger = yes
1647 - Make catalog respect ACL.
1648 - Add recycle count to Media record.
1649 - Add initial write date to Media record.
1650 - Fix store_yesno to be store_bitmask.
