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

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

407 1. When jobs are running and bacula for some reason crashes or if I do a
408 restart it remembers and jobs it was running before it crashed or restarted
409 as of now I loose all jobs if I restart it.
411 2. When spooling and in the midway if client is disconnected for instance a
412 laptop bacula completely discard the spool. It will be nice if it can write
413 that spool to tape so there will be some backups for that client if not all.
415 3. We have around 150 clients machines it will be nice to have a option to
416 upgrade all the client machines bacula version automatically.
418 4. Atleast one connection should be reserved for the bconsole so at heavy load
419 I should connect to the director via bconsole which at sometimes I can't
421 5. Another most important feature that is missing, say at 10am I manually
422 started backup of client abc and it was a full backup since client abc has
423 no backup history and at 10.30am bacula again automatically started backup of
424 client abc as that was in the schedule. So now we have 2 multiple Full
425 backups of the same client and if we again try to start a full backup of
426 client backup abc bacula won't complain. That should be fixed.
428 - Fix bpipe.c so that it does not modify results pointer.
429 ***FIXME*** calling sequence should be changed.
430 - For Windows disaster recovery see http://unattended.sf.net/
431 - regardless of the retention period, Bacula will not prune the
432 last Full, Diff, or Inc File data until a month after the
433 retention period for the last Full backup that was done.
434 - update volume=xxx --- add status=Full
435 - Remove old spool files on startup.
436 - Exclude SD spool/working directory.
437 - Refuse to prune last valid Full backup. Same goes for Catalog.
439 - Make a callback when Rerun failed levels is called.
440 - Give Python program access to Scheduled jobs.
441 - Add setting Volume State via Python.
442 - Python script to save with Python, not save, save with Bacula.
443 - Python script to do backup.
445 - Change the Priority, Client, Storage, JobStatus (error)
446 at the start of a job.
447 - Why is SpoolDirectory = /home/bacula/spool; not reported
448 as an error when writing a DVD?
449 - Make bootstrap file handle multiple MediaTypes (SD)
450 - Remove all old Device resource code in Dir and code to pass it
451 back in SD -- better, rework it to pass back device statistics.
452 - Check locking of resources -- be sure to lock devices where previously
453 resources were locked.
454 - The last part is left in the spool dir.
457 - In restore don't compare byte count on a raw device -- directory
458 entry does not contain bytes.
462 MA = (last_MA * 3 + rate) / 4
463 rate = (bytes - last_bytes) / (runtime - last_runtime)
464 - Max Vols limit in Pool off by one?
465 - Implement Files/Bytes,... stats for restore job.
466 - Implement Total Bytes Written, ... for restore job.
467 - Despool attributes simultaneously with data in a separate
468 thread, rejoined at end of data spooling.
469 - 7. Implement new Console commands to allow offlining/reserving drives,
470 and possibly manipulating the autochanger (much asked for).
471 - Add start/end date editing in messages (%t %T, %e?) ...
472 - Add ClientDefs similar to JobDefs.
473 - Print more info when bextract -p accepts a bad block.
474 - Fix FD JobType to be set before RunBeforeJob in FD.
475 - Look at adding full Volume and Pool information to a Volume
476 label so that bscan can get *all* the info.
477 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
478 and there is only one volume in the pool, refuse to do it -- otherwise
479 he fills the Volume, then immediately starts reusing it.
480 - Implement copies and stripes.
481 - Add history file to console.
482 - Each file on tape creates a JobMedia record. Peter has 4 million
483 files spread over 10000 tape files and four tapes. A restore takes
484 16 hours to build the restore list.
485 - Add and option to check if the file size changed during backup.
486 - Make sure SD deletes spool files on error exit.
487 - Delete old spool files when SD starts.
488 - When labeling tapes, if you enter 000026, Bacula uses
489 the tape index rather than the Volume name 000026.
490 - Add offline tape command to Bacula console.
492 Enter MediaId or Volume name: 32
493 Enter new Volume name: DLT-20Dec04

503 Do not forget to mount the drive!!!
504 - Bug: if a job is manually scheduled to run later, it does not appear
505 in any status report and cannot be cancelled.
507 ==== Keeping track of deleted/new files ====
508 - To mark files as deleted, run essentially a Verify to disk, and
509 when a file is found missing (MarkId != JobId), then create
510 a new File record with FileIndex == -1. This could be done
511 by the FD at the same time as the backup.
513 My "trick" for keeping track of deletions is the following.
514 Assuming the user turns on this option, after all the files
515 have been backed up, but before the job has terminated, the
516 FD will make a pass through all the files and send their
517 names to the DIR (*exactly* the same as what a Verify job
518 currently does). This will probably be done at the same
519 time the files are being sent to the SD avoiding a second
520 pass. The DIR will then compare that to what is stored in
521 the catalog. Any files in the catalog but not in what the
522 FD sent will receive a catalog File entry that indicates
523 that at that point in time the file was deleted. This
524 either transmitted to the FD or simultaneously computed in
525 the FD, so that the FD can put a record on the tape that
526 indicates that the file has been deleted at this point.
527 A delete file entry could potentially be one with a FileIndex
528 of 0 or perhaps -1 (need to check if FileIndex is used for
529 some other thing as many of the Bacula fields are "overloaded"
532 During a restore, any file initially picked up by some
533 backup (Full, ...) then subsequently having a File entry
534 marked "delete" will be removed from the tree, so will not
535 be restored. If a file with the same name is later OK it
536 will be inserted in the tree -- this already happens. All
537 will be consistent except for possible changes during the
540 Since I'm on the subject, some of you may be wondering what
541 the utility of the in memory tree is if you are going to
542 restore everything (at least it comes up from time to time
543 on the list). Well, it is still *very* useful because it
544 allows only the last item found for a particular filename
545 (full path) to be entered into the tree, and thus if a file
546 is backed up 10 times, only the last copy will be restored.
547 I recently (last Friday) restored a complete directory, and
548 the Full and all the Differential and Incremental backups
549 spanned 3 Volumes. The first Volume was not even mounted
550 because all the files had been updated and hence backed up
551 since the Full backup was made. In this case, the tree
552 saved me a *lot* of time.
554 Make sure this information is stored on the tape too so
555 that it can be restored directly from the tape.
557 All the code (with the exception of formally generating and
558 saving the delete file entries) already exists in the Verify
559 Catalog command. It explicitly recognizes added/deleted files since
560 the last InitCatalog. It is more or less a "simple" matter of
561 taking that code and adapting it slightly to work for backups.
563 Comments from Martin Simmons (I think they are all covered):
564 Ok, that should cover the basics. There are few issues though:
566 - Restore will depend on the catalog. I think it is better to include the
567 extra data in the backup as well, so it can be seen by bscan and bextract.
569 - I'm not sure if it will preserve multiple hard links to the same inode. Or
570 maybe adding or removing links will cause the data to be dumped again?
572 - I'm not sure if it will handle renamed directories. Possibly it will work
573 by dumping the whole tree under a renamed directory?
575 - It remains to be seen how the backup performance of the DIR's will be
576 affected when comparing the catalog for a large filesystem.
580 How about introducing a Type = MgmtPolicy job type? That job type would
581 be responsible for scanning the Bacula environment looking for specific
582 conditions, and submitting the appropriate jobs for implementing said
586 Name = "Migration-Policy"
588 Policy Selection Job Type = Migrate
589 Scope = "<keyword> <operator> <regexp>"
590 Threshold = "<keyword> <operator> <regexp>"
591 Job Template = <template-name>
594 Where <keyword> is any legal job keyword, <operator> is a comparison
595 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
596 appropriate regexp. I could see an argument for Scope and Threshold
597 being SQL queries if we want to support full flexibility. The
598 Migration-Policy job would then get scheduled as frequently as a site
599 felt necessary (suggested default: every 15 minutes).
604 Name = "Migration-Policy"
606 Policy Selection Job Type = Migration
608 Threshold = "Migration Selection Type = LowestUtil"
609 Job Template = "MigrationTemplate"
612 would select all pools for examination and generate a job based on
613 MigrationTemplate to automatically select the volume with the lowest
614 usage and migrate it's contents to the nextpool defined for that pool.
616 This policy abstraction would be really handy for adjusting the behavior
617 of Bacula according to site-selectable criteria (one thing that pops
618 into mind is Amanda's ability to automatically adjust backup levels
619 depending on various criteria).
625 - Add Pool/Storage override regression test.
626 - Add delete JobId to regression.
627 - Add a regression test for dbcheck.
628 - New test to add bscan to four-concurrent-jobs regression,
629 i.e. after the four-concurrent jobs zap the
630 database as is done in the bscan-test, then use bscan to
631 restore the database, do a restore and compare with the
633 - Add restore of specific JobId to regression (item 3
634 on the restore prompt)
635 - Add IPv6 to regression
636 - Add database test to regression. Test each function like delete,

640 - Win32 systems with FAT32 can be much slower than NTFS for
641 more than 1000 files per directory.
645 - A HOLD command to stop all jobs from starting.
646 - A PAUSE command to pause all running jobs ==> release the

652 === From Carsten Menke <bootsy52@gmx.net>
654 Following is a list of what I think in the situations where I'm faced with,
655 could be a usefull enhancement to bacula, which I'm certain other users will
656 benefit from as well.
658 1. NextJob/NextJobs Directive within a Job Resource in the form of
659 NextJobs = job1,job2.
662 I currently solved the problem with running multiple jobs each after each
663 by setting the Max Wait Time for a job to 8 hours, and give
664 the jobs different Priorities. However, there scenarios where
665 1 Job is directly depending on another job, so if the former job fails,
666 the job after it needn't to be run
667 while maybe other jobs should run despite of that
670 A Backup Job and a Verify job, if the backup job fails there is no need to run
671 the verify job, as the backup job already failed. However, one may like
672 to backup the Catalog to disk despite of that the main backup job failed.
675 I see that this is related to the Event Handlers which are on the ToDo
676 list, also it is maybe a good idea to check for the return value and
677 execute different actions based on the return value
680 3. offline capability to bconsole
683 Currently I use a script which I execute within the last Job via the
684 RunAfterJob Directive, to release and eject the tape.
685 So I have to call bconsole "release=Storage-Name" and afterwards
686 mt -f /dev/nst0 eject to get the tape out.
688 If I have multiple Storage Devices, than these may not be /dev/nst0 and
689 I have to modify the script or call it with parameters etc.
690 This would actually not be needed, as everything is already defined
691 in bacula-sd.conf and if I can invoke bconsole with the
692 storage name via $1 in the script than I'm done and information is
695 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
699 For the reason mentioned in 3. to have the ability to call a
700 script with /scripts/foobar %s and in the script use $1
701 to pass the Storage Name to bconsole
703 5. Setting Volume State within a Job Resource
706 Instead of using "Maximum Volume Jobs" in the Pool Resource,
707 I would have the possibilty to define
708 in a Job Resource that after this certain job is run, the Volume State
709 should be set to "Volume State = Used", this give more flexibility (IMHO).
711 6. Localization of Bacula Messages
714 Unfortunatley many,many people I work with don't speak english very well.
715 So if at least the Reporting messages would be localized then they
716 would understand that they have to change the tape,etc. etc.
718 I volunteer to do the german translations, and if I can convince my wife also
719 french and Morre (western african language).
721 7. OK, this is evil, probably bound to security risks and maybe not possible
722 due to the design of bacula.
724 Implementation of Backtics ( `command` ) for shell comand execution to
725 the "Label Format" Directive.
729 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
730 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
731 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
732 the localized name for the day of the week appended to the
733 format string. Then I have the tape labeled automatically with weekday
734 name in the correct language.
736 - Yes, that is surely the case. I probably should turn those into Warning
737 errors. In addition, you just made me think that it might not be bad to
738 add an option to check the file size after backing up the file and
739 report if it changes. This would be done as an option because it would
742 Kern, good idea. If you do do that, mention in the output: file
743 shrunk, or file expanded, just to make it obvious to the user
744 (without having to the refer to file size), just how the file size
747 Would this option be for all file, or just one file? Or a fileset?
748 - Make output from status use html table tags for nicely
749 presenting in a browser.
750 - Can one write tapes faster with 8192 byte block sizes?
751 - Document security problems with the same password for everyone in
752 rpm and Win32 releases.
753 - Browse generations of files.
754 - I've seen an error when my catalog's File table fills up. I
755 then have to recreate the File table with a larger maximum row
756 size. Relevant information is at
757 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
758 "Installing and Configuring MySQL" chapter should talk a bit
759 about this potential problem, and recommend a solution.
760 - For Solaris must use POSIX awk.
761 - Want speed of writing to tape while despooling.
762 - Supported autochanger:
770 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
771 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
772 - Add regex from http://www.pcre.org to Bacula for Win32.
773 - Use only shell tools no make in CDROM package.
774 - Include within include does it work?
775 - Implement a Pool of type Cleaning?
776 - Implement VolReadTime and VolWriteTime in SD
777 - Modify Backing up Your Database to include a bootstrap file.
778 - Think about making certain database errors fatal.
779 - Look at correcting the time jump in the scheduler for daylight
780 savings time changes.
781 - Add a "real" timer to network connections.
782 - Promote to Full = Time period
783 - Check dates entered by user for correctness (month/day/... ranges)
784 - Compress restore Volume listing by date and first file.
785 - Look at patches/bacula_db.b2z postgresql that loops during restore.
787 - Perhaps add read/write programs and/or plugins to FileSets.
788 - How to handle backing up portables ...
789 - Add some sort of guaranteed Interval for upgrading jobs.
790 - Can we write the state file after every job terminates? On Win32
791 the system crashes and the state file is not updated.
794 Documentation to do: (any release a little bit at a time)
795 - Doc to do unmount before removing magazine.
796 - Alternative to static linking "ldd prog" save all binaries listed,
797 restore them and point LD_LIBRARY_PATH to them.
798 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
799 - Document query file format.
800 - Add more documentation for bsr files.
801 - Document problems with Verify and pruning.
802 - Document how to use multiple databases.
803 - VXA drives have a "cleaning required"
804 indicator, but Exabyte recommends preventive cleaning after every 75
807 In this context, it should be noted that Exabyte has a command-line
808 vxatool utility available for free download. (The current version is
809 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
810 test the drive, unload tapes, change drive settings, flash new firmware,
812 Of particular interest in this context is that vxatool <device> -i will
813 report, among other details, the time since last cleaning in tape motion
814 minutes. This information can be retrieved (and settings changed, for
815 that matter) through the generic-SCSI device even when Bacula has the
816 regular tape device locked. (Needless to say, I don't recommend
817 changing tape settings while a job is running.)
818 - Lookup HP cleaning recommendations.
819 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
820 - Document doing table repair
823 ===================================
824 - Add macro expansions in JobDefs.
825 Run Before Job = "SomeFile %{Level} %{Client}"
826 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
827 - Use non-blocking network I/O but if no data is available, use
829 - Use gather write() for network I/O.
830 - Autorestart on crash.
831 - Add bandwidth limiting.
832 - Add acks every once and a while from the SD to keep
833 the line from timing out.
834 - When an error in input occurs and conio beeps, you can back
835 up through the prompt.
836 - Detect fixed tape block mode during positioning by looking at
837 block numbers in btape "test". Possibly adjust in Bacula.
838 - Fix list volumes to output volume retention in some other
839 units, perhaps via a directive.
840 - If opening a tape in read/write mode fails attempt to open
841 it in read-only mode, and mark the tape for read only.
842 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
843 with multiple priorities.
844 - If you use restore replace=never, the directory attributes for
845 non-existent directories will not be restored properly.
847 - see lzma401.zip in others directory for new compression
849 - Minimal autochanger handling in Bacula and in btape.
850 - Look into how tar does not save sockets and the possiblity of
851 not saving them in Bacula (Martin Simmons reported this).
852 - Fix restore jobs so that multiple jobs can run if they
853 are not using the same tape(s).
854 - Allow the user to select JobType for manual pruning/purging.
855 - bscan does not put first of two volumes back with all info in
857 - Implement the FreeBSD nodump flag in chflags.
858 - Figure out how to make named console messages go only to that
859 console and to the non-restricted console (new console class?).
860 - Make restricted console prompt for password if *ask* is set or
861 perhaps if password is undefined.
862 - Implement "from ISO-date/time every x hours/days/weeks/months" in
865 ==== from Marc Schoechlin
866 - the help-command should be more verbose
867 (it should explain the paramters of the different
869 -> its time-comsuming to consult the manual anytime
870 you need a special parameter
871 -> maybe its more easy to maintain this, if the
872 descriptions of that commands are outsourced to
874 - the cd-command should allow complete paths
875 i.e. cd /foo/bar/foo/bar
876 -> if a customer mails me the path to a certain file,
877 its faster to enter the specified directory
878 - if the password is not configured in bconsole.conf
879 you should be asked for it.
880 -> sometimes you like to do restore on a customer-machine
881 which shouldnt know the password for bacula.
882 -> adding the password to the file favours admins
883 to forget to remove the password after usage
885 the protection of that file is less important
886 - long-listed-output of commands should be scrollable
887 like the unix more/less-command does
888 -> if someone runs 200 and more machines, the lists could
889 be a little long and complex
890 - command-output should be shown column by column
891 to reduce scrolling and to increase clarity
893 - lsmark should list the selected files with full
895 - wildcards for selecting and file and directories would be nice
896 - any actions should be interuptable with STRG+C
897 - command-expansion would be pretty cool
899 - When the replace Never option is set, new directory permissions
900 are not restored. See bug 213. To fix this requires creating a
901 list of newly restored directories so that those directory
902 permissions *can* be restored.
903 - Compaction of Disk space by "migrating" Volumes that have pruned
904 Jobs (what criteria? size, #jobs, time).
905 - Add prune all command
906 - Document fact that purge can destroy a part of a restore by purging
907 one volume while others remain valid -- perhaps mark Jobs.
908 - Add multiple-media-types.txt
909 - look at mxt-changer.html
910 - Make ? do a help command (no return needed).
911 - Implement restore directory.
912 - Document streams and how to implement them.
913 - Try not to re-backup a file if a new hard link is added.
914 - Add feature to backup hard links only, but not the data.
915 - Fix stream handling to be simpler.
916 - Add Priority and Bootstrap to Run a Job.
917 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
919 - Remove View FileSet button from Run a Job dialog.
920 - Handle prompt for restore job at end of Restore command.
921 - Add display of total selected files to Restore window.
922 - Add tree pane to left of window.
923 - Add progress meter.
924 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
925 - Document writing to a CD/DVD with Bacula.
926 - Add a "base" package to the window installer for pthreadsVCE.dll
927 which is needed by all packages.
928 - Add message to user to check for fixed block size when the forward
929 space test fails in btape.
930 - When unmarking a directory check if all files below are unmarked and
931 then remove the + flag -- in the restore tree.
932 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
933 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
934 - Revisit the question of multiple Volumes (disk) on a single device.
935 - Add a block copy option to bcopy.
936 - Investigate adding Mac Resource Forks.
937 - Finish work on Gnome restore GUI.
938 - Fix "llist jobid=xx" where no fileset or client exists.
939 - For each job type (Admin, Restore, ...) require only the really necessary
940 fields.- Pass Director resource name as an option to the Console.
941 - Add a "batch" mode to the Console (no unsolicited queries, ...).
942 - Add a .list all files in the restore tree (probably also a list all files)
943 Do both a long and short form.
944 - Allow browsing the catalog to see all versions of a file (with
945 stat data on each file).
946 - Restore attributes of directory if replace=never set but directory
948 - Use SHA1 on authentication if possible.
949 - See comtest-xxx.zip for Windows code to talk to USB.
950 - Add John's appended files:
951 Appended = { /files/server/logs/http/*log }
952 and such files would be treated as follows.On a FULL backup, they would
953 be backed up like any other file.On an INCREMENTAL backup, where a
954 previous INCREMENTAL or FULL was already in thecatalogue and the length
955 of the file wasgreater than the length of the last backup, only thedata
956 added since the last backup will be dumped.On an INCREMENTAL backup, if
957 the length of the file is less than thelength of the file with the same
958 name last backed up, the completefile is dumped.On Windows systems, with
959 creation date of files, we can be evensmarter about this and not count
960 entirely upon the length.On a restore, the full and all incrementals
961 since it will beapplied in sequence to restore the file.
962 - Check new HAVE_WIN32 open bits.
963 - Check if the tape has moved before writing.
964 - Handling removable disks -- see below:
965 - Keep track of tape use time, and report when cleaning is necessary.
966 - Add FromClient and ToClient keywords on restore command (or
967 BackupClient RestoreClient).
968 - Implement a JobSet, which groups any number of jobs. If the
969 JobSet is started, all the jobs are started together.
970 Allow Pool, Level, and Schedule overrides.
971 - Enhance cancel to timeout BSOCK packets after a specific delay.
972 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
973 ua_status.!!! Thanks to Alan Brown for this tip.
974 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
975 correctly for multiple simultaneous jobs.
976 - Correct code so that FileSet MD5 is calculated for < and | filename
978 - Implement the Media record flag that indicates that the Volume does disk
980 - Implement VolAddr, which is used when Volume is addressed like a disk,
981 and form it from VolFile and VolBlock.
982 - Make multiple restore jobs for multiple media types specifying
983 the proper storage type.
984 - Fix fast block rejection (stored/read_record.c:118). It passes a null
985 pointer (rec) to try_repositioning().
986 - Look at extracting Win data from BackupRead.
987 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
988 which would take precidence over the Catalog "JobRetention".
989 - Implement Label Format in Add and Label console commands.
990 - Possibly up network buffers to 65K. Put on variable.
991 - Put email tape request delays on one or more variables. User wants
992 to cancel the job after a certain time interval. Maximum Mount Wait?
993 - Job, Client, Device, Pool, or Volume?
994 Is it possible to make this a directive which is *optional* in multiple
995 resources, like Level? If so, I think I'd make it an optional directive
996 in Job, Client, and Pool, with precedence such that Job overrides Client
997 which in turn overrides Pool.
999 - New Storage specifications:
1000 - Want to write to multiple storage devices simultaneously
1001 - Want to write to multiple storage devices sequentially (in one job)
1002 - Want to read/write simultaneously
1003 - Key is MediaType -- it must match
1005 Passed to SD as a sort of BSR record called Storage Specification
1009 MediaType -> Next MediaType
1011 Device -> Next Device
1013 Allow multiple Storage specifications
1021 Allow Multiple Pool specifications (note, Pool currently
1023 Allow Multiple MediaType specifications in Dir conf
1024 Allow Multiple Device specifications in Dir conf
1025 Perhaps keep this in a single SSR
1026 Tie a Volume to a specific device by using a MediaType that
1027 is contained in only one device.
1028 In SD allow Device to have Multiple MediaTypes
1030 - Ideas from Jerry Scharf:
1031 First let's point out some big pluses that bacula has for this
1033 more importantly it's active. Thank you so much for that
1034 even more important, it's not flaky
1035 it has an open access catalog, opening many possibilities
1036 it's pushing toward heterogeneous systems capability
1038 Macintosh file client
1039 macs are an interesting niche, but I fear a server is a rathole
1040 working bare iron recovery for windows
1041 the option for inc/diff backups not reset on fileset revision
1042 a) use both change and inode update time against base time
1043 b) do the full catalog check (expensive but accurate)
1044 sizing guide (how much system is needed to back up N systems/files)
1045 consultants on using bacula in building a disaster recovery system
1046 an integration guide
1047 or how to get at fancy things that one could do with bacula
1048 logwatch code for bacula logs (or similar)
1049 linux distro inclusion of bacula (brings good and bad, but necessary)
1050 win2k/XP server capability (icky but you asked)
1051 support for Oracle database ??
1053 - Look at adding SQL server and Exchange support for Windows.
1054 - Make dev->file and dev->block_num signed integers so that -1 can
1055 be an invalid value which happens with BSR.
1056 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1057 is needed to properly specify ranges.
1058 - Add progress of files/bytes to SD and FD.
1059 - Print warning message if FileId > 4 billion
1060 - do a "messages" before the first prompt in Console
1061 - Client does not show busy during Estimate command.
1062 - Implement Console mtx commands.
1063 - Implement a Mount Command and an Unmount Command where
1064 the users could specify a system command to be performed
1065 to do the mount, after which Bacula could attempt to
1066 read the device. This is for Removeable media such as a CDROM.
1067 - Most likely, this mount command would be invoked explicitly
1068 by the user using the current Console "mount" and "unmount"
1069 commands -- the Storage Daemon would do the right thing
1070 depending on the exact nature of the device.
1071 - As with tape drives, when Bacula wanted a new removable
1072 disk mounted, it would unmount the old one, and send a message
1073 to the user, who would then use "mount" as described above
1074 once he had actually inserted the disk.
1075 - Implement dump/print label to UA
1076 - Spool to disk only when the tape is full, then when a tape is hung move
1078 - bextract is sending everything to the log file ****FIXME****
1079 - Allow multiple Storage specifications (or multiple names on
1080 a single Storage specification) in the Job record. Thus a job
1081 can be backed up to a number of storage devices.
1082 - Implement some way for the File daemon to contact the Director
1083 to start a job or pass its DHCP obtained IP number.
1084 - Implement a query tape prompt/replace feature for a console
1085 - Copy console @ code to gnome2-console
1086 - Make AES the only encryption algorithm see
1087 http://csrc.nist.gov/CryptoToolkit/aes/). It's
1088 an officially adopted standard, has survived peer
1089 review, and provides keys up to 256 bits.
1090 - Take a careful look at SetACL http://setacl.sourceforge.net
1091 - Make tree walk routines like cd, ls, ... more user friendly
1092 by handling spaces better.
1093 - Make sure that Bacula rechecks the tape after the 20 min wait.
1094 - Set IO_NOWAIT on Bacula TCP/IP packets.
1095 - Try doing a raw partition backup and restore by mounting a
1097 - From Lars Kellers:
1098 Yes, it would allow to highly automatic the request for new tapes. If a
1099 tape is empty, bacula reads the barcodes (native or simulated), and if
1100 an unused tape is found, it runs the label command with all the
1101 necessary parameters.
1103 By the way can bacula automatically "move" an empty/purged volume say
1104 in the "short" pool to the "long" pool if this pool runs out of volume
1106 - What to do about "list files job=xxx".
1107 - Get and test MySQL 4.0
1108 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1109 file descriptor leak in Bacula.
1110 - Implement WrapCounters in Counters.
1111 - Add heartbeat from FD to SD if hb interval expires.
1112 - Can we dynamically change FileSets?
1113 - If pool specified to label command and Label Format is specified,
1114 automatically generate the Volume name.
1115 - Why can't SQL do the filename sort for restore?
1116 - Add ExhautiveRestoreSearch
1117 - Look at the possibility of loading only the necessary
1118 data into the restore tree (i.e. do it one directory at a
1119 time as the user walks through the tree).
1120 - Possibly use the hash code if the user selects all for a restore command.
1121 - Fix "restore all" to bypass building the tree.
1122 - Prohibit backing up archive device (findlib/find_one.c:128)
1123 - Implement Release Device in the Job resource to unmount a drive.
1124 - Implement Acquire Device in the Job resource to mount a drive,
1125 be sure this works with admin jobs so that the user can get
1126 prompted to insert the correct tape. Possibly some way to say to
1127 run the job but don't save the files.
1128 - Make things like list where a file is saved case independent for
1131 - Use autochanger to handle multiple devices.
1132 - On Windows with very long path names, it may be impossible to create
1133 a file (and thus restore it) because the total length is too long.
1134 We must cd into the directory then create the file without the
1136 - Implement a Recycle command
1137 - Test a second language e.g. french.
1138 - Start working on Base jobs.
1139 - Implement UnsavedFiles DB record.
1140 - From Phil Stracchino:
1141 It would probably be a per-client option, and would be called
1142 something like, say, "Automatically purge obsoleted jobs". What it
1143 would do is, when you successfully complete a Differential backup of a
1144 client, it would automatically purge all Incremental backups for that
1145 client that are rendered redundant by that Differential. Likewise,
1146 when a Full backup on a client completed, it would automatically purge
1147 all Differential and Incremental jobs obsoleted by that Full backup.
1148 This would let people minimize the number of tapes they're keeping on
1149 hand without having to master the art of retention times.
1150 - When doing a Backup send all attributes back to the Director, who
1151 would then figure out what files have been deleted.
1152 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1153 explicit permission to do so. It should also mark the tape in error
1154 if there is an error.
1155 - Cancel waiting for Client connect in SD if FD goes away.
1157 - Implement timeout in response() when it should come quickly.
1158 - Implement a Slot priority (loaded/not loaded).
1159 - Implement "vacation" Incremental only saves.
1160 - Implement create "FileSet"?
1161 - Add prefixlinks to where or not where absolute links to FD.
1162 - Issue message to mount a new tape before the rewind.
1163 - Simplified client job initiation for portables.
1164 - If SD cannot open a drive, make it periodically retry.
1165 - Add more of the config info to the tape label.
1167 - If tape is marked read-only, then try opening it read-only rather than
1168 failing, and remember that it cannot be written.
1169 - Refine SD waiting output:
1170 Device is being positioned

1174 - Figure out some way to estimate output size and to avoid splitting
1175 a backup across two Volumes -- this could be useful for writing CDROMs
1176 where you really prefer not to have it split -- not serious.
1177 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1178 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1179 actual data on the Volume and compare it.

1194 - Check if we can increase Bacula FD priorty in Win2000
1195 - Make sure the MaxVolFiles is fully implemented in SD
1196 - Check if both CatalogFiles and UseCatalog are set to SD.
1197 - Possibly add email to Watchdog if drive is unmounted too
1198 long and a job is waiting on the drive.

1290 report resource where report=group of messages
1291 - enhance scan_attrib and rename scan_jobtype, and
1292 fill in code for "since" option
1293 - Director needs a time after which the report status is sent
1294 anyway -- or better yet, a retry time for the job.
1295 - Don't reschedule a job if previous incarnation is still running.
1296 - Some way to automatically backup everything is needed????
1297 - Need a structure for pending actions:
1299 - termination status (part of buffered msgs?)
1301 Read, Write, Clean, Delete
1302 - Login to Bacula; Bacula users with different permissions:
1303 owner, group, user, quotas
1304 - Store info on each file system type (probably in the job header on tape.
1305 This could be the output of df; or perhaps some sort of /etc/mtab record.

1308 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1309 To: <kern@sibbald.com>
1310 Subject: RE: [Bacula-users] future large programming jobs
1311 Date: Thu, 26 Feb 2004 11:34:54 -0600
1313 I noticed the subject thread and thought I would offer the following
1314 merely as sources of ideas, i.e. something to think about, not even as
1315 strong as a request. In my former life (before retiring) I often
1316 dealt with backups and storage management issues/products as a
1317 developer and as a consultant. I am currently migrating my personal
1318 network from amanda to bacula specifically because of the ability to
1319 cross media boundaries during storing backups.
1320 Are you familiar with the commercial product called ADSM (I think IBM
1321 now sells it under the Tivoli label)? It has a couple of interesting
1322 ideas that may apply to the following topics.
1324 1. Migration: Consider that when you need to restore a system, there
1325 may be pressure to hurry. If all the information for a single client
1326 can eventually end up on the same media (and in chronological order),
1327 the restore is facillitated by not having to search past information
1328 from other clients. ADSM has the concept of "client affinity" that
1329 may be associated with it's storage pools. It seems to me that this
1330 concept (as an optional feature) might fit in your architecture for
1333 ADSM also has the concept of defining one or more storage pools as
1334 "copy pools" (almost mirrors, but only in the sense of contents).
1335 These pools provide the ability to have duplicte data stored both
1336 onsite and offsite. The copy process can be scheduled to be handled
1337 by their storage manager during periods when there is no backup
1338 activity. Again, the migration process might be a place to consider
1339 implementing something like this.
1342 > It strikes me that it would be very nice to be able to do things
1344 > have the Job(s) backing up the machines run, and once they have all

1350 > mechanism described below would probably make it very easy.
1352 This is the goal. In the first step (before events), you simply
1354 the Migration to tape later.
1356 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1357 the database. Once a file (unique by path and metadata such as dates,
1358 size, ownership, etc.) is in a copy pool, no more copies are made. In
1359 other words, when you start ADSM, it begins like your concept of a
1360 base job. After that it is in the "incremental" mode. You can
1361 configure the number of "generations" of files to be retained, plus a
1362 retention date after which even old generations are purged. The
1363 database tracks the contents of media and projects the percentage of
1364 each volume that is valid. When the valid content of a volume drops
1365 below a configured percentage, the valid data are migrated to another
1366 volume and the old volume is marked as empty. Note, this requires
1367 ADSM to have an idea of the contents of a client, i.e. marking the
1368 database when an existing file was deleted, but this would solve your
1369 issue of restoring a client without restoring deleted files.
1371 This is pretty far from what bacula now does, but if you are going to
1372 rip things up for Base jobs,.....
1373 Also, the benefits of this are huge for very large shops, especially
1374 with media robots, but are a pain for shops with manual media
1378 > Base jobs sound pretty useful, but I'm not dying for them.
1380 Nobody is dying for them, but when you see what it does, you will die
1383 3. Restoring deleted files: Since I think my comments in (2) above
1384 have low probability of implementation, I'll also suggest that you
1385 could approach the issue of deleted files by a mechanism of having the
1386 fd report to the dir, a list of all files on the client for every
1387 backup job. The dir could note in the database entry for each file
1388 the date that the file was seen. Then if a restore as of date X takes
1389 place, only files that exist from before X until after X would be
1390 restored. Probably the major cost here is the extra date container in
1391 each row of the files table.
1393 Thanks for "listening". I hope some of this helps. If you want to
1394 contact me, please send me an email - I read some but not all of the
1395 mailing list traffic and might miss a reply there.
1397 Please accept my compliments for bacula. It is doing a great job for
1398 me!! I sympathize with you in the need to wrestle with excelence in
1399 execution vs. excelence in feature inclusion.
1404 ==============================
1407 - Design at hierarchial storage for Bacula. Migration and Clone.
1408 - Implement FSM (File System Modules).
1409 - Audit M_ error codes to ensure they are correct and consistent.
1410 - Add variable break characters to lex analyzer.
1411 Either a bit mask or a string of chars so that
1412 the caller can change the break characters.
1413 - Make a single T_BREAK to replace T_COMMA, etc.
1414 - Ensure that File daemon and Storage daemon can
1415 continue a save if the Director goes down (this
1416 is NOT currently the case). Must detect socket error,
1417 buffer messages for later.
1418 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1419 - Add ability to backup to two Storage devices (two SD sessions) at
1420 the same time -- e.g. onsite, offsite.
1421 - Add the ability to consolidate old backup sets (basically do a restore
1422 to tape and appropriately update the catalog). Compress Volume sets.
1423 Might need to spool via file is only one drive is available.
1424 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1425 someway to do so with every volume that has less than x% valid
1429 Migration: Move a backup from one Volume to another
1430 Clone: Copy a backup -- two Volumes
1432 Bacula Migration is based on Jobs (apparently Networker is file by file).
1434 Migration triggered by:
1438 Highwater mark (keep total size)
1443 ======================================================
1445 It is somewhat like a Full save becomes an incremental since
1446 the Base job (or jobs) plus other non-base files.
1448 - A Base backup is same as Full backup, just different type.
1449 - New BaseFiles table that contains:
1451 BaseJobId - Base JobId referenced for this FileId (needed ???)
1452 JobId - JobId currently running
1453 FileId - File not backed up, exists in Base Job
1454 FileIndex - FileIndex from Base Job.
1455 i.e. for each base file that exists but is not saved because
1456 it has not changed, the File daemon sends the JobId, BaseId,
1457 FileId, FileIndex back to the Director who creates the DB entry.
1458 - To initiate a Base save, the Director sends the FD
1459 the FileId, and full filename for each file in the Base.
1460 - When the FD finds a Base file, he requests the Director to
1461 send him the full File entry (stat packet plus MD5), or
1462 conversely, the FD sends it to the Director and the Director
1463 says yes or no. This can be quite rapid if the FileId is kept
1464 by the FD for each Base Filename.
1465 - It is probably better to have the comparison done by the FD
1466 despite the fact that the File entry must be sent across the
1468 - An alternative would be to send the FD the whole File entry
1469 from the start. The disadvantage is that it requires a lot of
1470 space. The advantage is that it requires less communications
1472 - The Job record must be updated to indicate that one or more
1474 - At end of Job, FD returns:
1475 1. Count of base files/bytes not written to tape (i.e. matches)
1476 2. Count of base file that were saved i.e. had changed.
1477 - No tape record would be written for a Base file that matches, in the
1478 same way that no tape record is written for Incremental jobs where
1479 the file is not saved because it is unchanged.
1480 - On a restore, all the Base file records must explicitly be
1481 found from the BaseFile tape. I.e. for each Full save that is marked
1482 to have one or more Base Jobs, search the BaseFile for all occurrences
1484 - An optimization might be to make the BaseFile have:
1490 This would avoid the need to explicitly fetch each File record for
1491 the Base job. The Base Job record will be fetched to get the
1492 VolSessionId and VolSessionTime.
1493 =========================================================
1496 ==========================================================
1498 For each Incremental job that is run, there may be files that
1499 were found but not saved because they were locked (this applies
1500 only to Windows). Such a system could send back to the Director
1501 a list of Unsaved files.
1503 - New UnSavedFiles table that contains:
1507 - Then in the next Incremental job, the list of Unsaved Files will be
1508 feed to the FD, who will ensure that they are explicitly chosen even
1509 if standard date/time check would not have selected them.

1551 (just to verify it remembers where it came from, however it can be

1554 There needs to be a table of drive # to devices somewhere - If there are
1555 multiple changers or drives there may not be a 1:1 correspondance between
1556 changer drive number and system device name - and depending on the way the
1557 drives are hooked up to scsi busses, they may not be linearly numbered
1558 from an offset point either.something like
1560 Autochanger drives = 2
1561 Autochanger drive 0 = /dev/nst1
1562 Autochanger drive 1 = /dev/nst2
1563 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1564 times, not just for multidrive changers. For a 1 drive changer, that's
1570 MTX's manpage (1.2.15):
1571 unload [<slotnum>] [ <drivenum> ]
1572 Unloads media from drive <drivenum> into slot
1573 <slotnum>. If <drivenum> is omitted, defaults to
1574 drive 0 (as do all commands). If <slotnum> is
1575 omitted, defaults to the slot that the drive was
1576 loaded from. Note that there's currently no way
1577 to say 'unload drive 1's media to the slot it
1578 came from', other than to explicitly use that
1579 slot number as the destination.AB

1617 Handling removable disks
1619 From: Karl Cunningham <karlc@keckec.com>
1621 My backups are only to hard disk these days, in removable bays. This is my
1622 idea of how a backup to hard disk would work more smoothly. Some of these
1623 things Bacula does already, but I mention them for completeness. If others
1624 have better ways to do this, I'd like to hear about it.
1626 1. Accommodate several disks, rotated similar to how tapes are. Identified
1627 by partition volume ID or perhaps by the name of a subdirectory.
1628 2. Abort & notify the admin if the wrong disk is in the bay.
1629 3. Write backups to different subdirectories for each machine to be backed
1631 4. Volumes (files) get created as needed in the proper subdirectory, one
1633 5. When a disk is recycled, remove or zero all old backup files. This is
1634 important as the disk being recycled may be close to full. This may be
1635 better done manually since the backup files for many machines may be
1636 scattered in many subdirectories.
1641 - Make sure that all do_prompt() calls in Dir check for
1642 -1 (error) and -2 (cancel) returns.
1643 - Fix foreach_jcr() to have free_jcr() inside next().
1644 jcr=jcr_walk_start();
1645 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1648 - A Volume taken from Scratch should take on the retention period
1650 - Correct doc for Maximum Changer Wait (and others) accepting only
1652 - Implement status that shows why a job is being held in reserve, or
1653 rather why none of the drives are suitable.
1654 - Implement a way to disable a drive (so you can use the second
1655 drive of an autochanger, and the first one will not be used or
1657 - Make sure Maximum Volumes is respected in Pools when adding
1658 Volumes (e.g. when pulling a Scratch volume).
1659 - Keep same dcr when switching device ...
1660 - Implement code that makes the Dir aware that a drive is an
1661 autochanger (so the user doesn't need to use the Autochanger = yes
1663 - Make catalog respect ACL.
1664 - Add recycle count to Media record.
1665 - Add initial write date to Media record.
1666 - Fix store_yesno to be store_bitmask.
