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

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

473 - Add VolumeLock to prevent all but lock holder (SD) from updating
474 the Volume data (with the exception of VolumeState).
475 - The btape fill command does not seem to use the Autochanger
476 - Make Windows installer default to system disk drive.
477 - Look at using ioctl(FIOBMAP, ...) on Linux, and

498 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
499 - Implement a mode that says when a hard read error is
500 encountered, read many times (as it currently does), and if the
501 block cannot be read, skip to the next block, and try again. If
502 that fails, skip to the next file and try again, ...
504 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
505 insert into LevelType (LevelType,LevelTypeLong) values
509 - Show files/second in client status output.
510 - Add a recursive mark command (rmark) to restore.
511 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
512 of the same level and does not permit multiple simultaneous
513 running of that Job (i.e. lets any previous invocation finish
514 before doing Interval testing).
515 - Look at simplifying File exclusions.
516 - New directive "Delete purged Volumes"
517 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
518 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
519 see if it become stable and I just have to supervise
521 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
522 PoolId, and when it is empty remove it.
523 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
525 - Allow Check Labels to be used with Bacula labels.
526 - "Resuming" a failed backup (lost line for example) by using the
527 failed backup as a sort of "base" job.
529 - Email to the user when the tape is about to need changing x
530 days before it needs changing.
531 - Command to show next tape that will be used for a job even
532 if the job is not scheduled.
533 - From: Arunav Mandal <amandal@trolltech.com>
534 1. When jobs are running and bacula for some reason crashes or if I do a
535 restart it remembers and jobs it was running before it crashed or restarted
536 as of now I loose all jobs if I restart it.
538 2. When spooling and in the midway if client is disconnected for instance a
539 laptop bacula completely discard the spool. It will be nice if it can write
540 that spool to tape so there will be some backups for that client if not all.
542 3. We have around 150 clients machines it will be nice to have a option to
543 upgrade all the client machines bacula version automatically.
545 4. Atleast one connection should be reserved for the bconsole so at heavy load
546 I should connect to the director via bconsole which at sometimes I can't
548 5. Another most important feature that is missing, say at 10am I manually
549 started backup of client abc and it was a full backup since client abc has
550 no backup history and at 10.30am bacula again automatically started backup of
551 client abc as that was in the schedule. So now we have 2 multiple Full
552 backups of the same client and if we again try to start a full backup of
553 client backup abc bacula won't complain. That should be fixed.
555 - Fix bpipe.c so that it does not modify results pointer.
556 ***FIXME*** calling sequence should be changed.
557 - For Windows disaster recovery see http://unattended.sf.net/
558 - regardless of the retention period, Bacula will not prune the
559 last Full, Diff, or Inc File data until a month after the
560 retention period for the last Full backup that was done.
561 - update volume=xxx --- add status=Full
562 - Remove old spool files on startup.
563 - Exclude SD spool/working directory.
564 - Refuse to prune last valid Full backup. Same goes for Catalog.
566 - Make a callback when Rerun failed levels is called.
567 - Give Python program access to Scheduled jobs.
568 - Add setting Volume State via Python.
569 - Python script to save with Python, not save, save with Bacula.
570 - Python script to do backup.
572 - Change the Priority, Client, Storage, JobStatus (error)
573 at the start of a job.
574 - Why is SpoolDirectory = /home/bacula/spool; not reported
575 as an error when writing a DVD?
576 - Make bootstrap file handle multiple MediaTypes (SD)
577 - Remove all old Device resource code in Dir and code to pass it
578 back in SD -- better, rework it to pass back device statistics.
579 - Check locking of resources -- be sure to lock devices where previously
580 resources were locked.
581 - The last part is left in the spool dir.
584 - In restore don't compare byte count on a raw device -- directory
585 entry does not contain bytes.
589 MA = (last_MA * 3 + rate) / 4
590 rate = (bytes - last_bytes) / (runtime - last_runtime)
591 - Max Vols limit in Pool off by one?
592 - Implement Files/Bytes,... stats for restore job.
593 - Implement Total Bytes Written, ... for restore job.
594 - Despool attributes simultaneously with data in a separate
595 thread, rejoined at end of data spooling.
596 - 7. Implement new Console commands to allow offlining/reserving drives,
597 and possibly manipulating the autochanger (much asked for).
598 - Add start/end date editing in messages (%t %T, %e?) ...
599 - Add ClientDefs similar to JobDefs.
600 - Print more info when bextract -p accepts a bad block.
601 - Fix FD JobType to be set before RunBeforeJob in FD.
602 - Look at adding full Volume and Pool information to a Volume
603 label so that bscan can get *all* the info.
604 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
605 and there is only one volume in the pool, refuse to do it -- otherwise
606 he fills the Volume, then immediately starts reusing it.
607 - Implement copies and stripes.
608 - Add history file to console.
609 - Each file on tape creates a JobMedia record. Peter has 4 million
610 files spread over 10000 tape files and four tapes. A restore takes
611 16 hours to build the restore list.
612 - Add and option to check if the file size changed during backup.
613 - Make sure SD deletes spool files on error exit.
614 - Delete old spool files when SD starts.
615 - When labeling tapes, if you enter 000026, Bacula uses
616 the tape index rather than the Volume name 000026.
617 - Add offline tape command to Bacula console.
619 Enter MediaId or Volume name: 32
620 Enter new Volume name: DLT-20Dec04
621 Automatically selected Pool: Default
622 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

629 Label command failed for Volume DLT-20Dec04.
630 Do not forget to mount the drive!!!
631 - Bug: if a job is manually scheduled to run later, it does not appear
632 in any status report and cannot be cancelled.
634 ==== Keeping track of deleted/new files ====
635 - To mark files as deleted, run essentially a Verify to disk, and
636 when a file is found missing (MarkId != JobId), then create
637 a new File record with FileIndex == -1. This could be done
638 by the FD at the same time as the backup.
640 My "trick" for keeping track of deletions is the following.
641 Assuming the user turns on this option, after all the files
642 have been backed up, but before the job has terminated, the
643 FD will make a pass through all the files and send their
644 names to the DIR (*exactly* the same as what a Verify job
645 currently does). This will probably be done at the same
646 time the files are being sent to the SD avoiding a second
647 pass. The DIR will then compare that to what is stored in
648 the catalog. Any files in the catalog but not in what the
649 FD sent will receive a catalog File entry that indicates
650 that at that point in time the file was deleted. This
651 either transmitted to the FD or simultaneously computed in
652 the FD, so that the FD can put a record on the tape that
653 indicates that the file has been deleted at this point.
654 A delete file entry could potentially be one with a FileIndex
655 of 0 or perhaps -1 (need to check if FileIndex is used for
656 some other thing as many of the Bacula fields are "overloaded"
659 During a restore, any file initially picked up by some
660 backup (Full, ...) then subsequently having a File entry
661 marked "delete" will be removed from the tree, so will not
662 be restored. If a file with the same name is later OK it
663 will be inserted in the tree -- this already happens. All
664 will be consistent except for possible changes during the
667 Since I'm on the subject, some of you may be wondering what
668 the utility of the in memory tree is if you are going to
669 restore everything (at least it comes up from time to time
670 on the list). Well, it is still *very* useful because it
671 allows only the last item found for a particular filename
672 (full path) to be entered into the tree, and thus if a file
673 is backed up 10 times, only the last copy will be restored.
674 I recently (last Friday) restored a complete directory, and
675 the Full and all the Differential and Incremental backups
676 spanned 3 Volumes. The first Volume was not even mounted
677 because all the files had been updated and hence backed up
678 since the Full backup was made. In this case, the tree
679 saved me a *lot* of time.
681 Make sure this information is stored on the tape too so
682 that it can be restored directly from the tape.
684 All the code (with the exception of formally generating and
685 saving the delete file entries) already exists in the Verify
686 Catalog command. It explicitly recognizes added/deleted files since
687 the last InitCatalog. It is more or less a "simple" matter of
688 taking that code and adapting it slightly to work for backups.
690 Comments from Martin Simmons (I think they are all covered):
691 Ok, that should cover the basics. There are few issues though:
693 - Restore will depend on the catalog. I think it is better to include the
694 extra data in the backup as well, so it can be seen by bscan and bextract.
696 - I'm not sure if it will preserve multiple hard links to the same inode. Or
697 maybe adding or removing links will cause the data to be dumped again?
699 - I'm not sure if it will handle renamed directories. Possibly it will work
700 by dumping the whole tree under a renamed directory?
702 - It remains to be seen how the backup performance of the DIR's will be
703 affected when comparing the catalog for a large filesystem.
707 How about introducing a Type = MgmtPolicy job type? That job type would
708 be responsible for scanning the Bacula environment looking for specific
709 conditions, and submitting the appropriate jobs for implementing said
713 Name = "Migration-Policy"
715 Policy Selection Job Type = Migrate
716 Scope = "<keyword> <operator> <regexp>"
717 Threshold = "<keyword> <operator> <regexp>"
718 Job Template = <template-name>
721 Where <keyword> is any legal job keyword, <operator> is a comparison
722 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
723 appropriate regexp. I could see an argument for Scope and Threshold
724 being SQL queries if we want to support full flexibility. The
725 Migration-Policy job would then get scheduled as frequently as a site
726 felt necessary (suggested default: every 15 minutes).
731 Name = "Migration-Policy"
733 Policy Selection Job Type = Migration
735 Threshold = "Migration Selection Type = LowestUtil"
736 Job Template = "MigrationTemplate"
739 would select all pools for examination and generate a job based on
740 MigrationTemplate to automatically select the volume with the lowest
741 usage and migrate it's contents to the nextpool defined for that pool.
743 This policy abstraction would be really handy for adjusting the behavior
744 of Bacula according to site-selectable criteria (one thing that pops
745 into mind is Amanda's ability to automatically adjust backup levels
746 depending on various criteria).
752 - Add Pool/Storage override regression test.
753 - Add delete JobId to regression.
754 - Add a regression test for dbcheck.
755 - New test to add bscan to four-concurrent-jobs regression,
756 i.e. after the four-concurrent jobs zap the
757 database as is done in the bscan-test, then use bscan to
758 restore the database, do a restore and compare with the
760 - Add restore of specific JobId to regression (item 3
761 on the restore prompt)
762 - Add IPv6 to regression
763 - Add database test to regression. Test each function like delete,
766 - AntiVir can slow down backups on Win32 systems.
767 - Win32 systems with FAT32 can be much slower than NTFS for
768 more than 1000 files per directory.
772 - A HOLD command to stop all jobs from starting.
773 - A PAUSE command to pause all running jobs ==> release the

777 Media Type Write = LTO2, LTO3
779 === From Carsten Menke <bootsy52@gmx.net>
781 Following is a list of what I think in the situations where I'm faced with,
782 could be a usefull enhancement to bacula, which I'm certain other users will
783 benefit from as well.
785 1. NextJob/NextJobs Directive within a Job Resource in the form of
786 NextJobs = job1,job2.
789 I currently solved the problem with running multiple jobs each after each
790 by setting the Max Wait Time for a job to 8 hours, and give
791 the jobs different Priorities. However, there scenarios where
792 1 Job is directly depending on another job, so if the former job fails,
793 the job after it needn't to be run
794 while maybe other jobs should run despite of that
797 A Backup Job and a Verify job, if the backup job fails there is no need to run
798 the verify job, as the backup job already failed. However, one may like
799 to backup the Catalog to disk despite of that the main backup job failed.
802 I see that this is related to the Event Handlers which are on the ToDo
803 list, also it is maybe a good idea to check for the return value and
804 execute different actions based on the return value
807 3. offline capability to bconsole
810 Currently I use a script which I execute within the last Job via the
811 RunAfterJob Directive, to release and eject the tape.
812 So I have to call bconsole "release=Storage-Name" and afterwards
813 mt -f /dev/nst0 eject to get the tape out.
815 If I have multiple Storage Devices, than these may not be /dev/nst0 and
816 I have to modify the script or call it with parameters etc.
817 This would actually not be needed, as everything is already defined
818 in bacula-sd.conf and if I can invoke bconsole with the
819 storage name via $1 in the script than I'm done and information is
822 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
826 For the reason mentioned in 3. to have the ability to call a
827 script with /scripts/foobar %s and in the script use $1
828 to pass the Storage Name to bconsole
830 5. Setting Volume State within a Job Resource
833 Instead of using "Maximum Volume Jobs" in the Pool Resource,
834 I would have the possibilty to define
835 in a Job Resource that after this certain job is run, the Volume State
836 should be set to "Volume State = Used", this give more flexibility (IMHO).
838 6. Localization of Bacula Messages
841 Unfortunatley many,many people I work with don't speak english very well.
842 So if at least the Reporting messages would be localized then they
843 would understand that they have to change the tape,etc. etc.
845 I volunteer to do the german translations, and if I can convince my wife also
846 french and Morre (western african language).
848 7. OK, this is evil, probably bound to security risks and maybe not possible
849 due to the design of bacula.
851 Implementation of Backtics ( `command` ) for shell comand execution to
852 the "Label Format" Directive.
856 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
857 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
858 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
859 the localized name for the day of the week appended to the
860 format string. Then I have the tape labeled automatically with weekday
861 name in the correct language.
863 - Yes, that is surely the case. I probably should turn those into Warning
864 errors. In addition, you just made me think that it might not be bad to
865 add an option to check the file size after backing up the file and
866 report if it changes. This would be done as an option because it would
869 Kern, good idea. If you do do that, mention in the output: file
870 shrunk, or file expanded, just to make it obvious to the user
871 (without having to the refer to file size), just how the file size
874 Would this option be for all file, or just one file? Or a fileset?
875 - Make output from status use html table tags for nicely
876 presenting in a browser.
877 - Can one write tapes faster with 8192 byte block sizes?
878 - Document security problems with the same password for everyone in
879 rpm and Win32 releases.
880 - Browse generations of files.
881 - I've seen an error when my catalog's File table fills up. I
882 then have to recreate the File table with a larger maximum row
883 size. Relevant information is at
884 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
885 "Installing and Configuring MySQL" chapter should talk a bit
886 about this potential problem, and recommend a solution.
887 - For Solaris must use POSIX awk.
888 - Want speed of writing to tape while despooling.
889 - Supported autochanger:
897 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
898 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
899 - Add regex from http://www.pcre.org to Bacula for Win32.
900 - Use only shell tools no make in CDROM package.
901 - Include within include does it work?
902 - Implement a Pool of type Cleaning?
903 - Implement VolReadTime and VolWriteTime in SD
904 - Modify Backing up Your Database to include a bootstrap file.
905 - Think about making certain database errors fatal.
906 - Look at correcting the time jump in the scheduler for daylight
907 savings time changes.
908 - Add a "real" timer to network connections.
909 - Promote to Full = Time period
910 - Check dates entered by user for correctness (month/day/... ranges)
911 - Compress restore Volume listing by date and first file.
912 - Look at patches/bacula_db.b2z postgresql that loops during restore.
914 - Perhaps add read/write programs and/or plugins to FileSets.
915 - How to handle backing up portables ...
916 - Add some sort of guaranteed Interval for upgrading jobs.
917 - Can we write the state file after every job terminates? On Win32
918 the system crashes and the state file is not updated.
921 Documentation to do: (any release a little bit at a time)
922 - Doc to do unmount before removing magazine.
923 - Alternative to static linking "ldd prog" save all binaries listed,
924 restore them and point LD_LIBRARY_PATH to them.
925 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
926 - Document query file format.
927 - Add more documentation for bsr files.
928 - Document problems with Verify and pruning.
929 - Document how to use multiple databases.
930 - VXA drives have a "cleaning required"
931 indicator, but Exabyte recommends preventive cleaning after every 75
934 In this context, it should be noted that Exabyte has a command-line
935 vxatool utility available for free download. (The current version is
936 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
937 test the drive, unload tapes, change drive settings, flash new firmware,
939 Of particular interest in this context is that vxatool <device> -i will
940 report, among other details, the time since last cleaning in tape motion
941 minutes. This information can be retrieved (and settings changed, for
942 that matter) through the generic-SCSI device even when Bacula has the
943 regular tape device locked. (Needless to say, I don't recommend
944 changing tape settings while a job is running.)
945 - Lookup HP cleaning recommendations.
946 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
947 - Document doing table repair
950 ===================================
951 - Add macro expansions in JobDefs.
952 Run Before Job = "SomeFile %{Level} %{Client}"
953 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
954 - Use non-blocking network I/O but if no data is available, use
956 - Use gather write() for network I/O.
957 - Autorestart on crash.
958 - Add bandwidth limiting.
959 - Add acks every once and a while from the SD to keep
960 the line from timing out.
961 - When an error in input occurs and conio beeps, you can back
962 up through the prompt.
963 - Detect fixed tape block mode during positioning by looking at
964 block numbers in btape "test". Possibly adjust in Bacula.
965 - Fix list volumes to output volume retention in some other
966 units, perhaps via a directive.
967 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
968 with multiple priorities.
969 - If you use restore replace=never, the directory attributes for
970 non-existent directories will not be restored properly.
972 - see lzma401.zip in others directory for new compression
974 - Allow the user to select JobType for manual pruning/purging.
975 - bscan does not put first of two volumes back with all info in
977 - Implement the FreeBSD nodump flag in chflags.
978 - Figure out how to make named console messages go only to that
979 console and to the non-restricted console (new console class?).
980 - Make restricted console prompt for password if *ask* is set or
981 perhaps if password is undefined.
982 - Implement "from ISO-date/time every x hours/days/weeks/months" in
985 ==== from Marc Schoechlin
986 - the help-command should be more verbose
987 (it should explain the paramters of the different
989 -> its time-comsuming to consult the manual anytime
990 you need a special parameter
991 -> maybe its more easy to maintain this, if the
992 descriptions of that commands are outsourced to
994 - the cd-command should allow complete paths
995 i.e. cd /foo/bar/foo/bar
996 -> if a customer mails me the path to a certain file,
997 its faster to enter the specified directory
998 - if the password is not configured in bconsole.conf
999 you should be asked for it.
1000 -> sometimes you like to do restore on a customer-machine
1001 which shouldnt know the password for bacula.
1002 -> adding the password to the file favours admins
1003 to forget to remove the password after usage
1005 the protection of that file is less important
1006 - long-listed-output of commands should be scrollable
1007 like the unix more/less-command does
1008 -> if someone runs 200 and more machines, the lists could
1009 be a little long and complex
1010 - command-output should be shown column by column
1011 to reduce scrolling and to increase clarity
1013 - lsmark should list the selected files with full
1015 - wildcards for selecting and file and directories would be nice
1016 - any actions should be interuptable with STRG+C
1017 - command-expansion would be pretty cool
1019 - When the replace Never option is set, new directory permissions
1020 are not restored. See bug 213. To fix this requires creating a
1021 list of newly restored directories so that those directory
1022 permissions *can* be restored.
1023 - Add prune all command
1024 - Document fact that purge can destroy a part of a restore by purging
1025 one volume while others remain valid -- perhaps mark Jobs.
1026 - Add multiple-media-types.txt
1027 - look at mxt-changer.html
1028 - Make ? do a help command (no return needed).
1029 - Implement restore directory.
1030 - Document streams and how to implement them.
1031 - Try not to re-backup a file if a new hard link is added.
1032 - Add feature to backup hard links only, but not the data.
1033 - Fix stream handling to be simpler.
1034 - Add Priority and Bootstrap to Run a Job.
1035 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1037 - Remove View FileSet button from Run a Job dialog.
1038 - Handle prompt for restore job at end of Restore command.
1039 - Add display of total selected files to Restore window.
1040 - Add tree pane to left of window.
1041 - Add progress meter.
1042 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1043 - Add message to user to check for fixed block size when the forward
1044 space test fails in btape.
1045 - When unmarking a directory check if all files below are unmarked and
1046 then remove the + flag -- in the restore tree.
1047 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1048 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1049 - Revisit the question of multiple Volumes (disk) on a single device.
1050 - Add a block copy option to bcopy.
1051 - Finish work on Gnome restore GUI.
1052 - Fix "llist jobid=xx" where no fileset or client exists.
1053 - For each job type (Admin, Restore, ...) require only the really necessary
1054 fields.- Pass Director resource name as an option to the Console.
1055 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1056 - Add a .list all files in the restore tree (probably also a list all files)
1057 Do both a long and short form.
1058 - Allow browsing the catalog to see all versions of a file (with
1059 stat data on each file).
1060 - Restore attributes of directory if replace=never set but directory
1062 - Use SHA1 on authentication if possible.
1063 - See comtest-xxx.zip for Windows code to talk to USB.
1064 - Add John's appended files:
1065 Appended = { /files/server/logs/http/*log }
1066 and such files would be treated as follows.On a FULL backup, they would
1067 be backed up like any other file.On an INCREMENTAL backup, where a
1068 previous INCREMENTAL or FULL was already in thecatalogue and the length
1069 of the file wasgreater than the length of the last backup, only thedata
1070 added since the last backup will be dumped.On an INCREMENTAL backup, if
1071 the length of the file is less than thelength of the file with the same
1072 name last backed up, the completefile is dumped.On Windows systems, with
1073 creation date of files, we can be evensmarter about this and not count
1074 entirely upon the length.On a restore, the full and all incrementals
1075 since it will beapplied in sequence to restore the file.
1076 - Check new HAVE_WIN32 open bits.
1077 - Check if the tape has moved before writing.
1078 - Handling removable disks -- see below:
1079 - Keep track of tape use time, and report when cleaning is necessary.
1080 - Add FromClient and ToClient keywords on restore command (or
1081 BackupClient RestoreClient).
1082 - Implement a JobSet, which groups any number of jobs. If the
1083 JobSet is started, all the jobs are started together.
1084 Allow Pool, Level, and Schedule overrides.
1085 - Enhance cancel to timeout BSOCK packets after a specific delay.
1086 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1087 ua_status.!!! Thanks to Alan Brown for this tip.
1088 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1089 correctly for multiple simultaneous jobs.
1090 - Correct code so that FileSet MD5 is calculated for < and | filename
1092 - Implement the Media record flag that indicates that the Volume does disk
1094 - Implement VolAddr, which is used when Volume is addressed like a disk,
1095 and form it from VolFile and VolBlock.
1096 - Make multiple restore jobs for multiple media types specifying
1097 the proper storage type.
1098 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1099 pointer (rec) to try_repositioning().
1100 - Look at extracting Win data from BackupRead.
1101 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1102 which would take precidence over the Catalog "JobRetention".
1103 - Implement Label Format in Add and Label console commands.
1104 - Possibly up network buffers to 65K. Put on variable.
1105 - Put email tape request delays on one or more variables. User wants
1106 to cancel the job after a certain time interval. Maximum Mount Wait?
1107 - Job, Client, Device, Pool, or Volume?
1108 Is it possible to make this a directive which is *optional* in multiple
1109 resources, like Level? If so, I think I'd make it an optional directive
1110 in Job, Client, and Pool, with precedence such that Job overrides Client
1111 which in turn overrides Pool.
1113 - New Storage specifications:
1114 - Want to write to multiple storage devices simultaneously
1115 - Want to write to multiple storage devices sequentially (in one job)
1116 - Want to read/write simultaneously
1117 - Key is MediaType -- it must match
1119 Passed to SD as a sort of BSR record called Storage Specification
1123 MediaType -> Next MediaType
1125 Device -> Next Device
1127 Allow multiple Storage specifications
1135 Allow Multiple Pool specifications (note, Pool currently
1137 Allow Multiple MediaType specifications in Dir conf
1138 Allow Multiple Device specifications in Dir conf
1139 Perhaps keep this in a single SSR
1140 Tie a Volume to a specific device by using a MediaType that
1141 is contained in only one device.
1142 In SD allow Device to have Multiple MediaTypes
1144 - Ideas from Jerry Scharf:
1145 First let's point out some big pluses that bacula has for this
1147 more importantly it's active. Thank you so much for that
1148 even more important, it's not flaky

1167 - Look at adding SQL server and Exchange support for Windows.
1168 - Make dev->file and dev->block_num signed integers so that -1 can
1169 be an invalid value which happens with BSR.
1170 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1171 is needed to properly specify ranges.
1172 - Add progress of files/bytes to SD and FD.
1173 - Print warning message if FileId > 4 billion
1174 - do a "messages" before the first prompt in Console
1175 - Client does not show busy during Estimate command.
1176 - Implement Console mtx commands.
1177 - Implement a Mount Command and an Unmount Command where
1178 the users could specify a system command to be performed
1179 to do the mount, after which Bacula could attempt to
1180 read the device. This is for Removeable media such as a CDROM.
1181 - Most likely, this mount command would be invoked explicitly
1182 by the user using the current Console "mount" and "unmount"
1183 commands -- the Storage Daemon would do the right thing
1184 depending on the exact nature of the device.
1185 - As with tape drives, when Bacula wanted a new removable
1186 disk mounted, it would unmount the old one, and send a message
1187 to the user, who would then use "mount" as described above
1188 once he had actually inserted the disk.
1189 - Implement dump/print label to UA
1190 - Spool to disk only when the tape is full, then when a tape is hung move
1192 - bextract is sending everything to the log file ****FIXME****
1193 - Allow multiple Storage specifications (or multiple names on
1194 a single Storage specification) in the Job record. Thus a job
1195 can be backed up to a number of storage devices.
1196 - Implement some way for the File daemon to contact the Director
1197 to start a job or pass its DHCP obtained IP number.
1198 - Implement a query tape prompt/replace feature for a console
1199 - Copy console @ code to gnome2-console
1200 - Make tree walk routines like cd, ls, ... more user friendly
1201 by handling spaces better.
1202 - Make sure that Bacula rechecks the tape after the 20 min wait.
1203 - Set IO_NOWAIT on Bacula TCP/IP packets.
1204 - Try doing a raw partition backup and restore by mounting a
1206 - From Lars Kellers:
1207 Yes, it would allow to highly automatic the request for new tapes. If a
1208 tape is empty, bacula reads the barcodes (native or simulated), and if
1209 an unused tape is found, it runs the label command with all the
1210 necessary parameters.
1212 By the way can bacula automatically "move" an empty/purged volume say
1213 in the "short" pool to the "long" pool if this pool runs out of volume
1215 - What to do about "list files job=xxx".
1216 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1217 file descriptor leak in Bacula.
1218 - Implement WrapCounters in Counters.
1219 - Add heartbeat from FD to SD if hb interval expires.
1220 - Can we dynamically change FileSets?
1221 - If pool specified to label command and Label Format is specified,
1222 automatically generate the Volume name.
1223 - Why can't SQL do the filename sort for restore?
1224 - Add ExhautiveRestoreSearch
1225 - Look at the possibility of loading only the necessary
1226 data into the restore tree (i.e. do it one directory at a
1227 time as the user walks through the tree).
1228 - Possibly use the hash code if the user selects all for a restore command.
1229 - Fix "restore all" to bypass building the tree.
1230 - Prohibit backing up archive device (findlib/find_one.c:128)
1231 - Implement Release Device in the Job resource to unmount a drive.
1232 - Implement Acquire Device in the Job resource to mount a drive,
1233 be sure this works with admin jobs so that the user can get
1234 prompted to insert the correct tape. Possibly some way to say to
1235 run the job but don't save the files.
1236 - Make things like list where a file is saved case independent for
1238 - Use autochanger to handle multiple devices.
1239 - Implement a Recycle command
1240 - Start working on Base jobs.
1241 - Implement UnsavedFiles DB record.
1242 - From Phil Stracchino:
1243 It would probably be a per-client option, and would be called
1244 something like, say, "Automatically purge obsoleted jobs". What it
1245 would do is, when you successfully complete a Differential backup of a
1246 client, it would automatically purge all Incremental backups for that
1247 client that are rendered redundant by that Differential. Likewise,
1248 when a Full backup on a client completed, it would automatically purge
1249 all Differential and Incremental jobs obsoleted by that Full backup.
1250 This would let people minimize the number of tapes they're keeping on
1251 hand without having to master the art of retention times.
1252 - When doing a Backup send all attributes back to the Director, who
1253 would then figure out what files have been deleted.
1254 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1255 explicit permission to do so. It should also mark the tape in error
1256 if there is an error.
1257 - Cancel waiting for Client connect in SD if FD goes away.
1259 - Implement timeout in response() when it should come quickly.
1260 - Implement a Slot priority (loaded/not loaded).
1261 - Implement "vacation" Incremental only saves.
1262 - Implement create "FileSet"?
1263 - Add prefixlinks to where or not where absolute links to FD.
1264 - Issue message to mount a new tape before the rewind.
1265 - Simplified client job initiation for portables.
1266 - If SD cannot open a drive, make it periodically retry.
1267 - Add more of the config info to the tape label.
1269 - Refine SD waiting output:
1270 Device is being positioned
1271 > Device is being positioned for append
1272 > Device is being positioned to file x
1274 - Figure out some way to estimate output size and to avoid splitting
1275 a backup across two Volumes -- this could be useful for writing CDROMs
1276 where you really prefer not to have it split -- not serious.
1277 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1278 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1279 actual data on the Volume and compare it.
1280 - Implement Bacula plugins -- design API
1281 - Make bcopy read through bad tape records.
1282 - Program files (i.e. execute a program to read/write files).
1283 Pass read date of last backup, size of file last time.
1284 - Add Signature type to File DB record.
1285 - CD into subdirectory when open()ing files for backup to
1286 speed up things. Test with testfind().
1287 - Priority job to go to top of list.
1288 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1289 - Implement some way for the Console to dynamically create a job.
1290 - Solaris -I on tar for include list
1291 - Need a verbose mode in restore, perhaps to bsr.
1292 - bscan without -v is too quiet -- perhaps show jobs.
1293 - Add code to reject whole blocks if not wanted on restore.
1294 - Check if we can increase Bacula FD priorty in Win2000
1295 - Make sure the MaxVolFiles is fully implemented in SD
1296 - Check if both CatalogFiles and UseCatalog are set to SD.
1297 - Possibly add email to Watchdog if drive is unmounted too
1298 long and a job is waiting on the drive.
1299 - After unmount, if restore job started, ask to mount.
1300 - Add UA rc and history files.
1301 - put termcap (used by console) in ./configure and
1302 allow -with-termcap-dir.
1303 - Fix Autoprune for Volumes to respect need for full save.
1304 - Compare tape to Client files (attributes, or attributes and data)
1305 - Make all database Ids 64 bit.
1306 - Allow console commands to detach or run in background.
1307 - Add SD message variables to control operator wait time
1308 - Maximum Operator Wait
1309 - Minimum Message Interval
1310 - Maximum Message Interval
1311 - Send Operator message when cannot read tape label.
1312 - Verify level=Volume (scan only), level=Data (compare of data to file).
1313 Verify level=Catalog, level=InitCatalog
1315 - Add keyword search to show command in Console.
1316 - Events : tape has more than xxx bytes.
1317 - Complete code in Bacula Resources -- this will permit
1318 reading a new config file at any time.
1319 - Handle ctl-c in Console
1320 - Implement script driven addition of File daemon to config files.
1321 - Think about how to make Bacula work better with File (non-tape) archives.
1322 - Write Unix emulator for Windows.
1323 - Put memory utilization in Status output of each daemon
1324 if full status requested or if some level of debug on.
1325 - Make database type selectable by .conf files i.e. at runtime
1326 - Set flag for uname -a. Add to Volume label.
1327 - Restore files modified after date
1328 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1329 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1330 - Timout a job or terminate if link goes down, or reopen link and query.
1331 - Concept of precious tapes (cannot be reused).
1332 - Make bcopy copy with a single tape drive.
1333 - Permit changing ownership during restore.

1347 - Autolabel should be specified by DIR instead of SD.
1349 - Add media capacity
1350 - AutoScan (check checksum of tape)
1351 - Format command = "format /dev/nst0"
1355 - Seek resolution (usually corresponds to buffer size)
1356 - EODErrorCode=ENOSPC or code
1357 - Partial Read error code
1358 - Partial write error code
1359 - Nonformatted read error
1360 - Nonformatted write error
1361 - WriteProtected error
1365 - IgnoreCloseErrors=yes
1375 - FD sends unsaved file list to Director at end of job (see
1377 - File daemon should build list of files skipped, and then
1378 at end of save retry and report any errors.
1379 - Write a Storage daemon that uses pipes and
1380 standard Unix programs to write to the tape.
1382 - Need something that monitors the JCR queue and
1383 times out jobs by asking the deamons where they are.
1384 - Enhance Jmsg code to permit buffering and saving to disk.
1385 - device driver = "xxxx" for drives.
1386 - Verify from Volume
1387 - Ensure that /dev/null works
1388 - Need report class for messages. Perhaps
1389 report resource where report=group of messages
1390 - enhance scan_attrib and rename scan_jobtype, and
1391 fill in code for "since" option
1392 - Director needs a time after which the report status is sent
1393 anyway -- or better yet, a retry time for the job.
1394 - Don't reschedule a job if previous incarnation is still running.
1395 - Some way to automatically backup everything is needed????
1396 - Need a structure for pending actions:
1398 - termination status (part of buffered msgs?)
1400 Read, Write, Clean, Delete
1401 - Login to Bacula; Bacula users with different permissions:
1402 owner, group, user, quotas
1403 - Store info on each file system type (probably in the job header on tape.
1404 This could be the output of df; or perhaps some sort of /etc/mtab record.
1406 ========= ideas ===============
1407 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1408 To: <kern@sibbald.com>
1409 Subject: RE: [Bacula-users] future large programming jobs
1410 Date: Thu, 26 Feb 2004 11:34:54 -0600
1412 I noticed the subject thread and thought I would offer the following
1413 merely as sources of ideas, i.e. something to think about, not even as
1414 strong as a request. In my former life (before retiring) I often
1415 dealt with backups and storage management issues/products as a
1416 developer and as a consultant. I am currently migrating my personal
1417 network from amanda to bacula specifically because of the ability to
1418 cross media boundaries during storing backups.
1419 Are you familiar with the commercial product called ADSM (I think IBM
1420 now sells it under the Tivoli label)? It has a couple of interesting
1421 ideas that may apply to the following topics.
1423 1. Migration: Consider that when you need to restore a system, there
1424 may be pressure to hurry. If all the information for a single client
1425 can eventually end up on the same media (and in chronological order),
1426 the restore is facillitated by not having to search past information
1427 from other clients. ADSM has the concept of "client affinity" that
1428 may be associated with it's storage pools. It seems to me that this
1429 concept (as an optional feature) might fit in your architecture for
1432 ADSM also has the concept of defining one or more storage pools as
1433 "copy pools" (almost mirrors, but only in the sense of contents).
1434 These pools provide the ability to have duplicte data stored both
1435 onsite and offsite. The copy process can be scheduled to be handled
1436 by their storage manager during periods when there is no backup
1437 activity. Again, the migration process might be a place to consider
1438 implementing something like this.
1441 > It strikes me that it would be very nice to be able to do things
1443 > have the Job(s) backing up the machines run, and once they have all

1449 > mechanism described below would probably make it very easy.
1451 This is the goal. In the first step (before events), you simply
1453 the Migration to tape later.
1455 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1456 the database. Once a file (unique by path and metadata such as dates,
1457 size, ownership, etc.) is in a copy pool, no more copies are made. In
1458 other words, when you start ADSM, it begins like your concept of a
1459 base job. After that it is in the "incremental" mode. You can
1460 configure the number of "generations" of files to be retained, plus a
1461 retention date after which even old generations are purged. The
1462 database tracks the contents of media and projects the percentage of
1463 each volume that is valid. When the valid content of a volume drops
1464 below a configured percentage, the valid data are migrated to another
1465 volume and the old volume is marked as empty. Note, this requires
1466 ADSM to have an idea of the contents of a client, i.e. marking the
1467 database when an existing file was deleted, but this would solve your
1468 issue of restoring a client without restoring deleted files.
1470 This is pretty far from what bacula now does, but if you are going to
1471 rip things up for Base jobs,.....
1472 Also, the benefits of this are huge for very large shops, especially
1473 with media robots, but are a pain for shops with manual media
1477 > Base jobs sound pretty useful, but I'm not dying for them.
1479 Nobody is dying for them, but when you see what it does, you will die
1482 3. Restoring deleted files: Since I think my comments in (2) above
1483 have low probability of implementation, I'll also suggest that you
1484 could approach the issue of deleted files by a mechanism of having the
1485 fd report to the dir, a list of all files on the client for every
1486 backup job. The dir could note in the database entry for each file
1487 the date that the file was seen. Then if a restore as of date X takes
1488 place, only files that exist from before X until after X would be
1489 restored. Probably the major cost here is the extra date container in
1490 each row of the files table.
1492 Thanks for "listening". I hope some of this helps. If you want to
1493 contact me, please send me an email - I read some but not all of the
1494 mailing list traffic and might miss a reply there.
1496 Please accept my compliments for bacula. It is doing a great job for
1497 me!! I sympathize with you in the need to wrestle with excelence in
1498 execution vs. excelence in feature inclusion.
1503 ==============================
1506 - Design at hierarchial storage for Bacula. Migration and Clone.
1507 - Implement FSM (File System Modules).
1508 - Audit M_ error codes to ensure they are correct and consistent.
1509 - Add variable break characters to lex analyzer.
1510 Either a bit mask or a string of chars so that
1511 the caller can change the break characters.
1512 - Make a single T_BREAK to replace T_COMMA, etc.
1513 - Ensure that File daemon and Storage daemon can
1514 continue a save if the Director goes down (this
1515 is NOT currently the case). Must detect socket error,
1516 buffer messages for later.
1517 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1518 - Add ability to backup to two Storage devices (two SD sessions) at
1519 the same time -- e.g. onsite, offsite.
1520 - Add the ability to consolidate old backup sets (basically do a restore
1521 to tape and appropriately update the catalog). Compress Volume sets.
1522 Might need to spool via file is only one drive is available.
1523 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1524 someway to do so with every volume that has less than x% valid
1528 Migration: Move a backup from one Volume to another
1529 Clone: Copy a backup -- two Volumes
1532 ======================================================
1534 It is somewhat like a Full save becomes an incremental since
1535 the Base job (or jobs) plus other non-base files.
1537 - A Base backup is same as Full backup, just different type.
1538 - New BaseFiles table that contains:
1540 BaseJobId - Base JobId referenced for this FileId (needed ???)
1541 JobId - JobId currently running
1542 FileId - File not backed up, exists in Base Job
1543 FileIndex - FileIndex from Base Job.
1544 i.e. for each base file that exists but is not saved because
1545 it has not changed, the File daemon sends the JobId, BaseId,
1546 FileId, FileIndex back to the Director who creates the DB entry.
1547 - To initiate a Base save, the Director sends the FD
1548 the FileId, and full filename for each file in the Base.
1549 - When the FD finds a Base file, he requests the Director to
1550 send him the full File entry (stat packet plus MD5), or
1551 conversely, the FD sends it to the Director and the Director
1552 says yes or no. This can be quite rapid if the FileId is kept
1553 by the FD for each Base Filename.
1554 - It is probably better to have the comparison done by the FD
1555 despite the fact that the File entry must be sent across the
1557 - An alternative would be to send the FD the whole File entry
1558 from the start. The disadvantage is that it requires a lot of
1559 space. The advantage is that it requires less communications
1561 - The Job record must be updated to indicate that one or more
1563 - At end of Job, FD returns:
1564 1. Count of base files/bytes not written to tape (i.e. matches)
1565 2. Count of base file that were saved i.e. had changed.
1566 - No tape record would be written for a Base file that matches, in the
1567 same way that no tape record is written for Incremental jobs where
1568 the file is not saved because it is unchanged.
1569 - On a restore, all the Base file records must explicitly be
1570 found from the BaseFile tape. I.e. for each Full save that is marked
1571 to have one or more Base Jobs, search the BaseFile for all occurrences
1573 - An optimization might be to make the BaseFile have:
1579 This would avoid the need to explicitly fetch each File record for
1580 the Base job. The Base Job record will be fetched to get the
1581 VolSessionId and VolSessionTime.
1582 =========================================================
1585 ==========================================================
1587 For each Incremental job that is run, there may be files that
1588 were found but not saved because they were locked (this applies
1589 only to Windows). Such a system could send back to the Director
1590 a list of Unsaved files.
1592 - New UnSavedFiles table that contains:
1596 - Then in the next Incremental job, the list of Unsaved Files will be
1597 feed to the FD, who will ensure that they are explicitly chosen even
1598 if standard date/time check would not have selected them.

1643 There needs to be a table of drive # to devices somewhere - If there are
1644 multiple changers or drives there may not be a 1:1 correspondance between
1645 changer drive number and system device name - and depending on the way the
1646 drives are hooked up to scsi busses, they may not be linearly numbered
1647 from an offset point either.something like
1649 Autochanger drives = 2
1650 Autochanger drive 0 = /dev/nst1
1651 Autochanger drive 1 = /dev/nst2
1652 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1653 times, not just for multidrive changers. For a 1 drive changer, that's
1659 MTX's manpage (1.2.15):
1660 unload [<slotnum>] [ <drivenum> ]
1661 Unloads media from drive <drivenum> into slot
1662 <slotnum>. If <drivenum> is omitted, defaults to
1663 drive 0 (as do all commands). If <slotnum> is
1664 omitted, defaults to the slot that the drive was
1665 loaded from. Note that there's currently no way
1666 to say 'unload drive 1's media to the slot it
1667 came from', other than to explicitly use that
1668 slot number as the destination.AB

1706 Handling removable disks
1708 From: Karl Cunningham <karlc@keckec.com>
1710 My backups are only to hard disk these days, in removable bays. This is my
1711 idea of how a backup to hard disk would work more smoothly. Some of these
1712 things Bacula does already, but I mention them for completeness. If others
1713 have better ways to do this, I'd like to hear about it.
1715 1. Accommodate several disks, rotated similar to how tapes are. Identified
1716 by partition volume ID or perhaps by the name of a subdirectory.
1717 2. Abort & notify the admin if the wrong disk is in the bay.
1718 3. Write backups to different subdirectories for each machine to be backed
1720 4. Volumes (files) get created as needed in the proper subdirectory, one
1722 5. When a disk is recycled, remove or zero all old backup files. This is
1723 important as the disk being recycled may be close to full. This may be
1724 better done manually since the backup files for many machines may be
1725 scattered in many subdirectories.
1730 - Why the heck doesn't bacula drop root priviledges before connecting to
1732 - Look at using posix_fadvise(2) for backups -- see bug #751.
1733 Possibly add the code at findlib/bfile.c:795
1734 /* TCP socket options */
1735 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1736 - Fix bnet_connect() code to set a timer and to use time to
1738 - Implement 4th argument to make_catalog_backup that passes hostname.
1739 - Test FIFO backup/restore -- make regression
1740 - Please mount volume "xxx" on Storage device ... should also list
1741 Pool and MediaType in case user needs to create a new volume.
1742 - On restore add Restore Client, Original Client.

1751 - Check if gnome-console works with TLS.
1752 - the director seg faulted when I omitted the pool directive from a
1753 job resource. I was experimenting and thought it redundant that I had
1754 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1755 apparently not. This happened when I removed the pool directive and
1756 started the director.
1757 - Add Where: client:/.... to restore job report.
1758 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1759 does the right thing.
1760 - FD-SD quick disconnect
1761 - Building the in memory restore tree is slow.
