80 - finish implementation of fdcalled -- see ua_run.c:105
81 - Fix problem in postgresql.c in my_postgresql_query, where the
82 generation of the error message doesn't differentiate result==NULL

108 - Ensure that each device in an Autochanger has a different
110 - Add Catalog = to Pool resource so that pools will exist
111 in only one catalog -- currently Pools are "global".
112 - Look at sg_logs -a /dev/sg0 for getting soft errors.
113 - btape "test" command with Offline on Unmount = yes
115 This test is essential to Bacula.

134 - Why doesn't @"xxx abc" work in a conf file?
135 - Figure out some way to "automatically" backup conf changes.
136 - Add the OS version back to the Win32 client info.
137 - Restarted jobs have a NULL in the from field.
138 - Modify SD status command to indicate when the SD is writing
139 to a DVD (the device is not open -- see bug #732).
140 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
141 and possibly changing the blobs into varchar.
142 - Ensure that the SD re-reads the Media record if the JobFiles
143 does not match -- it may have been updated by another job.
144 - Look at moving the Storage directive from the Job to the
145 Pool in the default conf files.

213 - Change dbcheck to tell users to use native tools for fixing
214 broken databases, and to ensure they have the proper indexes.
215 - add udev rules for Bacula devices.
216 - If a job terminates, the DIR connection can close before the
217 Volume info is updated, leaving the File count wrong.
218 - Look at why SIGPIPE during connection can cause seg fault in
219 writing the daemon message, when Dir dropped to bacula:bacula
220 - Look at zlib 32 => 64 problems.
221 - Possibly turn on St. Bernard code.
222 - Fix bextract to restore ACLs, or better yet, use common routines.
223 - Do we migrate appendable Volumes?
224 - Remove queue.c code.
225 - Print warning message if LANG environment variable does not specify
227 - New dot commands from Arno.
228 .show device=xxx lists information from one storage device, including
229 devices (I'm not even sure that information exists in the DIR...)
230 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
231 better machine-readable output like "Ok" or "Error busy"
232 .move eject device=xxx toslot=yyy the same as above, but with a new
233 target slot. The catalog should be updated accordingly.

264 - Possibly allow SD to spool even if a tape is not mounted.
265 - It appears to me that you have run into some sort of race
266 condition where two threads want to use the same Volume and they
267 were both given access. Normally that is no problem. However,
268 one thread wanted the particular Volume in drive 0, but it was
269 loaded into drive 1 so it decided to unload it from drive 1 and
270 then loaded it into drive 0, while the second thread went on
271 thinking that the Volume could be used in drive 1 not realizing
272 that in between time, it was loaded in drive 0.
273 I'll look at the code to see if there is some way we can avoid
274 this kind of problem. Probably the best solution is to make the
275 first thread simply start using the Volume in drive 1 rather than
276 transferring it to drive 0.
277 - Fix re-read of last block to check if job has actually written
278 a block, and check if block was written by a different job
279 (i.e. multiple simultaneous jobs writing).
280 - Figure out how to configure query.sql. Suggestion to use m4:
281 == changequote.m4 ===
282 changequote(`[',`]')dnl
283 ==== query.sql.in ===
284 :List next 20 volumes to expire
286 Pool.Name AS PoolName,
291 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
293 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
297 ON Media.PoolId=Pool.PoolId
298 WHERE Media.LastWritten>0
302 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
304 The problem is that it requires m4, which is not present on all machines
306 - Given all the problems with FIFOs, I think the solution is to do something a
307 little different, though I will look at the code and see if there is not some
308 simple solution (i.e. some bug that was introduced). What might be a better
309 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
310 write data to a program rather than the FIFO. For example, suppose you
315 Then, I could imagine if you backup and restore this file with a direct
316 reference as is currently done for fifos, instead, during backup Bacula will
319 /home/kern/my-fifo.backup
321 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
324 /home/kern/my-fifo.restore
326 and send the data backed up to stdout. These programs can either be an
327 executable or a shell script and they need only read/write to stdin/stdout.
329 I think this would give a lot of flexibility to the user without making any
330 significant changes to Bacula.

347 === Migration from David ===
348 What I'd like to see:
351 Name = "<poolname>-migrate"
355 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
356 Client | PoolResidence | Volume | JobName | SQLquery
357 Migration Selection Pattern = "regexp"
358 Next Pool = <override>
361 There should be no need for a Level (migration is always Full, since you
362 don't calculate differential/incremental differences for migration),
363 Storage should be determined by the volume types in the pool, and Client
364 is really a selection issue. Migration should always occur to the
365 NextPool defined in the pool definition. If no nextpool is defined, the
366 job should end with a reason of "no place to go". If Next Pool statement
367 is present, we override the check in the pool definition and use the
370 Here's how I'd define Migration Selection Types:
373 Client -- Migrate data from selected client only. Migration Selection
374 Pattern regexp provides pattern to select client names, eg ^FS00* makes
375 all client names starting with FS00 eligible for migration.
377 Jobname -- Migration all jobs matching name. Migration Selection Pattern
378 regexp provides pattern to select jobnames existing in pool.
380 Volume -- Migrate all data on specified volumes. Migration Selection
381 Pattern regexp provides selection criteria for volumes to be migrated.
382 Volumes must exist in pool to be eligible for migration.
386 LowestUtil -- Identify the volume in the pool with the least data on it
387 and empty it. No Migration Selection Pattern required.
389 OldestVol -- Identify the LRU volume with data written, and empty it. No
390 Migration Selection Pattern required.
392 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
393 (starting with most full volumes) until pool occupancy drops below
394 <lowmig>. Pool highmig and lowmig values are in pool definition, no
395 Migration Selection Pattern required.
399 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
400 Migration Selection Pattern contains SQL query to execute; should return
401 a list of 1 or more jobuids to migrate.
403 PoolResidence -- Migrate data sitting in pool for longer than
404 PoolResidence value in pool definition. Migration Selection Pattern
405 optional; if specified, override value in pool definition (value in

521 - http://www.dwheeler.com/essays/commercial-floss.html
522 - Add VolumeLock to prevent all but lock holder (SD) from updating
523 the Volume data (with the exception of VolumeState).
524 - The btape fill command does not seem to use the Autochanger
525 - Make Windows installer default to system disk drive.
526 - Look at using ioctl(FIOBMAP, ...) on Linux, and
527 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
528 Win32 for sparse files.

546 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
547 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
548 - Implement a mode that says when a hard read error is
549 encountered, read many times (as it currently does), and if the
550 block cannot be read, skip to the next block, and try again. If
551 that fails, skip to the next file and try again, ...
553 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
554 insert into LevelType (LevelType,LevelTypeLong) values
558 - Show files/second in client status output.
559 - Add a recursive mark command (rmark) to restore.
560 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
561 of the same level and does not permit multiple simultaneous
562 running of that Job (i.e. lets any previous invocation finish
563 before doing Interval testing).
564 - Look at simplifying File exclusions.
565 - New directive "Delete purged Volumes"
566 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
567 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
568 see if it become stable and I just have to supervise
570 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
571 PoolId, and when it is empty remove it.
572 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
574 - Allow Check Labels to be used with Bacula labels.
575 - "Resuming" a failed backup (lost line for example) by using the
576 failed backup as a sort of "base" job.
578 - Email to the user when the tape is about to need changing x
579 days before it needs changing.
580 - Command to show next tape that will be used for a job even
581 if the job is not scheduled.
582 - From: Arunav Mandal <amandal@trolltech.com>
583 1. When jobs are running and bacula for some reason crashes or if I do a
584 restart it remembers and jobs it was running before it crashed or restarted
585 as of now I loose all jobs if I restart it.
587 2. When spooling and in the midway if client is disconnected for instance a
588 laptop bacula completely discard the spool. It will be nice if it can write
589 that spool to tape so there will be some backups for that client if not all.
591 3. We have around 150 clients machines it will be nice to have a option to
592 upgrade all the client machines bacula version automatically.
594 4. Atleast one connection should be reserved for the bconsole so at heavy load
595 I should connect to the director via bconsole which at sometimes I can't
597 5. Another most important feature that is missing, say at 10am I manually
598 started backup of client abc and it was a full backup since client abc has
599 no backup history and at 10.30am bacula again automatically started backup of
600 client abc as that was in the schedule. So now we have 2 multiple Full
601 backups of the same client and if we again try to start a full backup of
602 client backup abc bacula won't complain. That should be fixed.
604 - Fix bpipe.c so that it does not modify results pointer.
605 ***FIXME*** calling sequence should be changed.
606 - For Windows disaster recovery see http://unattended.sf.net/
607 - regardless of the retention period, Bacula will not prune the
608 last Full, Diff, or Inc File data until a month after the
609 retention period for the last Full backup that was done.
610 - update volume=xxx --- add status=Full
611 - Remove old spool files on startup.
612 - Exclude SD spool/working directory.
613 - Refuse to prune last valid Full backup. Same goes for Catalog.
615 - Make a callback when Rerun failed levels is called.
616 - Give Python program access to Scheduled jobs.
617 - Add setting Volume State via Python.
618 - Python script to save with Python, not save, save with Bacula.
619 - Python script to do backup.
621 - Change the Priority, Client, Storage, JobStatus (error)
622 at the start of a job.
623 - Why is SpoolDirectory = /home/bacula/spool; not reported
624 as an error when writing a DVD?
625 - Make bootstrap file handle multiple MediaTypes (SD)
626 - Remove all old Device resource code in Dir and code to pass it
627 back in SD -- better, rework it to pass back device statistics.
628 - Check locking of resources -- be sure to lock devices where previously
629 resources were locked.
630 - The last part is left in the spool dir.
633 - In restore don't compare byte count on a raw device -- directory
634 entry does not contain bytes.
638 MA = (last_MA * 3 + rate) / 4
639 rate = (bytes - last_bytes) / (runtime - last_runtime)
640 - Max Vols limit in Pool off by one?
641 - Implement Files/Bytes,... stats for restore job.
642 - Implement Total Bytes Written, ... for restore job.
643 - Despool attributes simultaneously with data in a separate
644 thread, rejoined at end of data spooling.
645 - 7. Implement new Console commands to allow offlining/reserving drives,
646 and possibly manipulating the autochanger (much asked for).
647 - Add start/end date editing in messages (%t %T, %e?) ...
648 - Add ClientDefs similar to JobDefs.
649 - Print more info when bextract -p accepts a bad block.
650 - Fix FD JobType to be set before RunBeforeJob in FD.
651 - Look at adding full Volume and Pool information to a Volume
652 label so that bscan can get *all* the info.
653 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
654 and there is only one volume in the pool, refuse to do it -- otherwise
655 he fills the Volume, then immediately starts reusing it.
656 - Implement copies and stripes.
657 - Add history file to console.
658 - Each file on tape creates a JobMedia record. Peter has 4 million
659 files spread over 10000 tape files and four tapes. A restore takes
660 16 hours to build the restore list.
661 - Add and option to check if the file size changed during backup.
662 - Make sure SD deletes spool files on error exit.
663 - Delete old spool files when SD starts.
664 - When labeling tapes, if you enter 000026, Bacula uses
665 the tape index rather than the Volume name 000026.
666 - Add offline tape command to Bacula console.
668 Enter MediaId or Volume name: 32
669 Enter new Volume name: DLT-20Dec04
670 Automatically selected Pool: Default
671 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

673 block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
674 Error writing final EOF to tape. This tape may not be readable.
675 dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
676 askdir.c:219 NULL Volume name. This shouldn't happen!!!
677 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
678 Label command failed for Volume DLT-20Dec04.
679 Do not forget to mount the drive!!!
680 - Bug: if a job is manually scheduled to run later, it does not appear
681 in any status report and cannot be cancelled.
683 ==== Keeping track of deleted/new files ====
684 - To mark files as deleted, run essentially a Verify to disk, and
685 when a file is found missing (MarkId != JobId), then create
686 a new File record with FileIndex == -1. This could be done
687 by the FD at the same time as the backup.
689 My "trick" for keeping track of deletions is the following.
690 Assuming the user turns on this option, after all the files
691 have been backed up, but before the job has terminated, the
692 FD will make a pass through all the files and send their
693 names to the DIR (*exactly* the same as what a Verify job
694 currently does). This will probably be done at the same
695 time the files are being sent to the SD avoiding a second
696 pass. The DIR will then compare that to what is stored in
697 the catalog. Any files in the catalog but not in what the
698 FD sent will receive a catalog File entry that indicates
699 that at that point in time the file was deleted. This
700 either transmitted to the FD or simultaneously computed in
701 the FD, so that the FD can put a record on the tape that
702 indicates that the file has been deleted at this point.
703 A delete file entry could potentially be one with a FileIndex
704 of 0 or perhaps -1 (need to check if FileIndex is used for
705 some other thing as many of the Bacula fields are "overloaded"
708 During a restore, any file initially picked up by some
709 backup (Full, ...) then subsequently having a File entry
710 marked "delete" will be removed from the tree, so will not
711 be restored. If a file with the same name is later OK it
712 will be inserted in the tree -- this already happens. All
713 will be consistent except for possible changes during the
716 Since I'm on the subject, some of you may be wondering what
717 the utility of the in memory tree is if you are going to
718 restore everything (at least it comes up from time to time
719 on the list). Well, it is still *very* useful because it
720 allows only the last item found for a particular filename
721 (full path) to be entered into the tree, and thus if a file
722 is backed up 10 times, only the last copy will be restored.
723 I recently (last Friday) restored a complete directory, and
724 the Full and all the Differential and Incremental backups
725 spanned 3 Volumes. The first Volume was not even mounted
726 because all the files had been updated and hence backed up
727 since the Full backup was made. In this case, the tree
728 saved me a *lot* of time.
730 Make sure this information is stored on the tape too so
731 that it can be restored directly from the tape.
733 All the code (with the exception of formally generating and
734 saving the delete file entries) already exists in the Verify
735 Catalog command. It explicitly recognizes added/deleted files since
736 the last InitCatalog. It is more or less a "simple" matter of
737 taking that code and adapting it slightly to work for backups.
739 Comments from Martin Simmons (I think they are all covered):
740 Ok, that should cover the basics. There are few issues though:
742 - Restore will depend on the catalog. I think it is better to include the
743 extra data in the backup as well, so it can be seen by bscan and bextract.
745 - I'm not sure if it will preserve multiple hard links to the same inode. Or
746 maybe adding or removing links will cause the data to be dumped again?
748 - I'm not sure if it will handle renamed directories. Possibly it will work
749 by dumping the whole tree under a renamed directory?
751 - It remains to be seen how the backup performance of the DIR's will be
752 affected when comparing the catalog for a large filesystem.
756 How about introducing a Type = MgmtPolicy job type? That job type would
757 be responsible for scanning the Bacula environment looking for specific
758 conditions, and submitting the appropriate jobs for implementing said
762 Name = "Migration-Policy"
764 Policy Selection Job Type = Migrate
765 Scope = "<keyword> <operator> <regexp>"
766 Threshold = "<keyword> <operator> <regexp>"
767 Job Template = <template-name>
770 Where <keyword> is any legal job keyword, <operator> is a comparison
771 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
772 appropriate regexp. I could see an argument for Scope and Threshold
773 being SQL queries if we want to support full flexibility. The
774 Migration-Policy job would then get scheduled as frequently as a site
775 felt necessary (suggested default: every 15 minutes).
780 Name = "Migration-Policy"
782 Policy Selection Job Type = Migration
784 Threshold = "Migration Selection Type = LowestUtil"
785 Job Template = "MigrationTemplate"
788 would select all pools for examination and generate a job based on
789 MigrationTemplate to automatically select the volume with the lowest
790 usage and migrate it's contents to the nextpool defined for that pool.
792 This policy abstraction would be really handy for adjusting the behavior
793 of Bacula according to site-selectable criteria (one thing that pops
794 into mind is Amanda's ability to automatically adjust backup levels
795 depending on various criteria).
801 - Add Pool/Storage override regression test.
802 - Add delete JobId to regression.
803 - Add a regression test for dbcheck.
804 - New test to add bscan to four-concurrent-jobs regression,
805 i.e. after the four-concurrent jobs zap the
806 database as is done in the bscan-test, then use bscan to
807 restore the database, do a restore and compare with the
809 - Add restore of specific JobId to regression (item 3
810 on the restore prompt)
811 - Add IPv6 to regression
812 - Add database test to regression. Test each function like delete,
815 - AntiVir can slow down backups on Win32 systems.
816 - Win32 systems with FAT32 can be much slower than NTFS for
817 more than 1000 files per directory.
821 - A HOLD command to stop all jobs from starting.
822 - A PAUSE command to pause all running jobs ==> release the

828 === From Carsten Menke <bootsy52@gmx.net>
830 Following is a list of what I think in the situations where I'm faced with,
831 could be a usefull enhancement to bacula, which I'm certain other users will
832 benefit from as well.
834 1. NextJob/NextJobs Directive within a Job Resource in the form of
835 NextJobs = job1,job2.
838 I currently solved the problem with running multiple jobs each after each
839 by setting the Max Wait Time for a job to 8 hours, and give
840 the jobs different Priorities. However, there scenarios where
841 1 Job is directly depending on another job, so if the former job fails,
842 the job after it needn't to be run
843 while maybe other jobs should run despite of that
846 A Backup Job and a Verify job, if the backup job fails there is no need to run
847 the verify job, as the backup job already failed. However, one may like
848 to backup the Catalog to disk despite of that the main backup job failed.
851 I see that this is related to the Event Handlers which are on the ToDo
852 list, also it is maybe a good idea to check for the return value and
853 execute different actions based on the return value
856 3. offline capability to bconsole
859 Currently I use a script which I execute within the last Job via the
860 RunAfterJob Directive, to release and eject the tape.
861 So I have to call bconsole "release=Storage-Name" and afterwards
862 mt -f /dev/nst0 eject to get the tape out.
864 If I have multiple Storage Devices, than these may not be /dev/nst0 and
865 I have to modify the script or call it with parameters etc.
866 This would actually not be needed, as everything is already defined
867 in bacula-sd.conf and if I can invoke bconsole with the
868 storage name via $1 in the script than I'm done and information is
871 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
875 For the reason mentioned in 3. to have the ability to call a
876 script with /scripts/foobar %s and in the script use $1
877 to pass the Storage Name to bconsole
879 5. Setting Volume State within a Job Resource
882 Instead of using "Maximum Volume Jobs" in the Pool Resource,
883 I would have the possibilty to define
884 in a Job Resource that after this certain job is run, the Volume State
885 should be set to "Volume State = Used", this give more flexibility (IMHO).
887 6. Localization of Bacula Messages
890 Unfortunatley many,many people I work with don't speak english very well.
891 So if at least the Reporting messages would be localized then they
892 would understand that they have to change the tape,etc. etc.
894 I volunteer to do the german translations, and if I can convince my wife also
895 french and Morre (western african language).
897 7. OK, this is evil, probably bound to security risks and maybe not possible
898 due to the design of bacula.
900 Implementation of Backtics ( `command` ) for shell comand execution to
901 the "Label Format" Directive.
905 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
906 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
907 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
908 the localized name for the day of the week appended to the
909 format string. Then I have the tape labeled automatically with weekday
910 name in the correct language.
912 - Yes, that is surely the case. I probably should turn those into Warning
913 errors. In addition, you just made me think that it might not be bad to
914 add an option to check the file size after backing up the file and
915 report if it changes. This would be done as an option because it would
918 Kern, good idea. If you do do that, mention in the output: file
919 shrunk, or file expanded, just to make it obvious to the user
920 (without having to the refer to file size), just how the file size
923 Would this option be for all file, or just one file? Or a fileset?
924 - Make output from status use html table tags for nicely
925 presenting in a browser.
926 - Can one write tapes faster with 8192 byte block sizes?
927 - Document security problems with the same password for everyone in
928 rpm and Win32 releases.
929 - Browse generations of files.
930 - I've seen an error when my catalog's File table fills up. I
931 then have to recreate the File table with a larger maximum row
932 size. Relevant information is at
933 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
934 "Installing and Configuring MySQL" chapter should talk a bit
935 about this potential problem, and recommend a solution.
936 - For Solaris must use POSIX awk.
937 - Want speed of writing to tape while despooling.
938 - Supported autochanger:
946 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
947 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
948 - Add regex from http://www.pcre.org to Bacula for Win32.
949 - Use only shell tools no make in CDROM package.
950 - Include within include does it work?
951 - Implement a Pool of type Cleaning?
952 - Implement VolReadTime and VolWriteTime in SD
953 - Modify Backing up Your Database to include a bootstrap file.
954 - Think about making certain database errors fatal.
955 - Look at correcting the time jump in the scheduler for daylight
956 savings time changes.
957 - Add a "real" timer to network connections.
958 - Promote to Full = Time period
959 - Check dates entered by user for correctness (month/day/... ranges)
960 - Compress restore Volume listing by date and first file.
961 - Look at patches/bacula_db.b2z postgresql that loops during restore.
963 - Perhaps add read/write programs and/or plugins to FileSets.
964 - How to handle backing up portables ...
965 - Add some sort of guaranteed Interval for upgrading jobs.
966 - Can we write the state file after every job terminates? On Win32
967 the system crashes and the state file is not updated.
970 Documentation to do: (any release a little bit at a time)
971 - Doc to do unmount before removing magazine.
972 - Alternative to static linking "ldd prog" save all binaries listed,
973 restore them and point LD_LIBRARY_PATH to them.
974 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
975 - Document query file format.
976 - Add more documentation for bsr files.
977 - Document problems with Verify and pruning.
978 - Document how to use multiple databases.
979 - VXA drives have a "cleaning required"
980 indicator, but Exabyte recommends preventive cleaning after every 75
983 In this context, it should be noted that Exabyte has a command-line
984 vxatool utility available for free download. (The current version is
985 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
986 test the drive, unload tapes, change drive settings, flash new firmware,
988 Of particular interest in this context is that vxatool <device> -i will
989 report, among other details, the time since last cleaning in tape motion
990 minutes. This information can be retrieved (and settings changed, for
991 that matter) through the generic-SCSI device even when Bacula has the
992 regular tape device locked. (Needless to say, I don't recommend
993 changing tape settings while a job is running.)
994 - Lookup HP cleaning recommendations.
995 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
996 - Document doing table repair
999 ===================================
1000 - Add macro expansions in JobDefs.
1001 Run Before Job = "SomeFile %{Level} %{Client}"
1002 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
1003 - Use non-blocking network I/O but if no data is available, use
1005 - Use gather write() for network I/O.
1006 - Autorestart on crash.
1007 - Add bandwidth limiting.
1008 - Add acks every once and a while from the SD to keep
1009 the line from timing out.
1010 - When an error in input occurs and conio beeps, you can back
1011 up through the prompt.
1012 - Detect fixed tape block mode during positioning by looking at
1013 block numbers in btape "test". Possibly adjust in Bacula.
1014 - Fix list volumes to output volume retention in some other
1015 units, perhaps via a directive.
1016 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
1017 with multiple priorities.
1018 - If you use restore replace=never, the directory attributes for
1019 non-existent directories will not be restored properly.
1021 - see lzma401.zip in others directory for new compression
1023 - Allow the user to select JobType for manual pruning/purging.
1024 - bscan does not put first of two volumes back with all info in
1026 - Implement the FreeBSD nodump flag in chflags.
1027 - Figure out how to make named console messages go only to that
1028 console and to the non-restricted console (new console class?).
1029 - Make restricted console prompt for password if *ask* is set or
1030 perhaps if password is undefined.
1031 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1034 ==== from Marc Schoechlin
1035 - the help-command should be more verbose
1036 (it should explain the paramters of the different
1038 -> its time-comsuming to consult the manual anytime
1039 you need a special parameter
1040 -> maybe its more easy to maintain this, if the
1041 descriptions of that commands are outsourced to
1043 - the cd-command should allow complete paths
1044 i.e. cd /foo/bar/foo/bar
1045 -> if a customer mails me the path to a certain file,
1046 its faster to enter the specified directory
1047 - if the password is not configured in bconsole.conf
1048 you should be asked for it.
1049 -> sometimes you like to do restore on a customer-machine
1050 which shouldnt know the password for bacula.
1051 -> adding the password to the file favours admins
1052 to forget to remove the password after usage
1054 the protection of that file is less important
1055 - long-listed-output of commands should be scrollable
1056 like the unix more/less-command does
1057 -> if someone runs 200 and more machines, the lists could
1058 be a little long and complex
1059 - command-output should be shown column by column
1060 to reduce scrolling and to increase clarity
1062 - lsmark should list the selected files with full
1064 - wildcards for selecting and file and directories would be nice
1065 - any actions should be interuptable with STRG+C
1066 - command-expansion would be pretty cool
1068 - When the replace Never option is set, new directory permissions
1069 are not restored. See bug 213. To fix this requires creating a
1070 list of newly restored directories so that those directory
1071 permissions *can* be restored.
1072 - Add prune all command
1073 - Document fact that purge can destroy a part of a restore by purging
1074 one volume while others remain valid -- perhaps mark Jobs.
1075 - Add multiple-media-types.txt
1076 - look at mxt-changer.html
1077 - Make ? do a help command (no return needed).
1078 - Implement restore directory.
1079 - Document streams and how to implement them.
1080 - Try not to re-backup a file if a new hard link is added.
1081 - Add feature to backup hard links only, but not the data.
1082 - Fix stream handling to be simpler.
1083 - Add Priority and Bootstrap to Run a Job.
1084 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1086 - Remove View FileSet button from Run a Job dialog.
1087 - Handle prompt for restore job at end of Restore command.
1088 - Add display of total selected files to Restore window.
1089 - Add tree pane to left of window.
1090 - Add progress meter.
1091 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1092 - Add message to user to check for fixed block size when the forward
1093 space test fails in btape.
1094 - When unmarking a directory check if all files below are unmarked and
1095 then remove the + flag -- in the restore tree.
1096 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1097 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1098 - Revisit the question of multiple Volumes (disk) on a single device.
1099 - Add a block copy option to bcopy.
1100 - Finish work on Gnome restore GUI.
1101 - Fix "llist jobid=xx" where no fileset or client exists.
1102 - For each job type (Admin, Restore, ...) require only the really necessary
1103 fields.- Pass Director resource name as an option to the Console.
1104 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1105 - Add a .list all files in the restore tree (probably also a list all files)
1106 Do both a long and short form.
1107 - Allow browsing the catalog to see all versions of a file (with
1108 stat data on each file).
1109 - Restore attributes of directory if replace=never set but directory
1111 - Use SHA1 on authentication if possible.
1112 - See comtest-xxx.zip for Windows code to talk to USB.
1113 - Add John's appended files:
1114 Appended = { /files/server/logs/http/*log }
1115 and such files would be treated as follows.On a FULL backup, they would
1116 be backed up like any other file.On an INCREMENTAL backup, where a
1117 previous INCREMENTAL or FULL was already in thecatalogue and the length
1118 of the file wasgreater than the length of the last backup, only thedata
1119 added since the last backup will be dumped.On an INCREMENTAL backup, if
1120 the length of the file is less than thelength of the file with the same
1121 name last backed up, the completefile is dumped.On Windows systems, with
1122 creation date of files, we can be evensmarter about this and not count
1123 entirely upon the length.On a restore, the full and all incrementals
1124 since it will beapplied in sequence to restore the file.
1125 - Check new HAVE_WIN32 open bits.
1126 - Check if the tape has moved before writing.
1127 - Handling removable disks -- see below:
1128 - Keep track of tape use time, and report when cleaning is necessary.
1129 - Add FromClient and ToClient keywords on restore command (or
1130 BackupClient RestoreClient).
1131 - Implement a JobSet, which groups any number of jobs. If the
1132 JobSet is started, all the jobs are started together.
1133 Allow Pool, Level, and Schedule overrides.
1134 - Enhance cancel to timeout BSOCK packets after a specific delay.
1135 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1136 ua_status.!!! Thanks to Alan Brown for this tip.
1137 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1138 correctly for multiple simultaneous jobs.
1139 - Correct code so that FileSet MD5 is calculated for < and | filename
1141 - Implement the Media record flag that indicates that the Volume does disk
1143 - Implement VolAddr, which is used when Volume is addressed like a disk,
1144 and form it from VolFile and VolBlock.
1145 - Make multiple restore jobs for multiple media types specifying
1146 the proper storage type.
1147 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1148 pointer (rec) to try_repositioning().
1149 - Look at extracting Win data from BackupRead.
1150 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1151 which would take precidence over the Catalog "JobRetention".
1152 - Implement Label Format in Add and Label console commands.
1153 - Possibly up network buffers to 65K. Put on variable.
1154 - Put email tape request delays on one or more variables. User wants
1155 to cancel the job after a certain time interval. Maximum Mount Wait?
1156 - Job, Client, Device, Pool, or Volume?
1157 Is it possible to make this a directive which is *optional* in multiple
1158 resources, like Level? If so, I think I'd make it an optional directive
1159 in Job, Client, and Pool, with precedence such that Job overrides Client
1160 which in turn overrides Pool.
1162 - New Storage specifications:
1163 - Want to write to multiple storage devices simultaneously
1164 - Want to write to multiple storage devices sequentially (in one job)
1165 - Want to read/write simultaneously
1166 - Key is MediaType -- it must match
1168 Passed to SD as a sort of BSR record called Storage Specification
1172 MediaType -> Next MediaType
1174 Device -> Next Device
1176 Allow multiple Storage specifications
1184 Allow Multiple Pool specifications (note, Pool currently
1186 Allow Multiple MediaType specifications in Dir conf
1187 Allow Multiple Device specifications in Dir conf
1188 Perhaps keep this in a single SSR
1189 Tie a Volume to a specific device by using a MediaType that
1190 is contained in only one device.
1191 In SD allow Device to have Multiple MediaTypes
1193 - Ideas from Jerry Scharf:
1194 First let's point out some big pluses that bacula has for this
1196 more importantly it's active. Thank you so much for that
1197 even more important, it's not flaky
1198 it has an open access catalog, opening many possibilities
1199 it's pushing toward heterogeneous systems capability
1201 Macintosh file client
1202 macs are an interesting niche, but I fear a server is a rathole
1203 working bare iron recovery for windows
1204 the option for inc/diff backups not reset on fileset revision
1205 a) use both change and inode update time against base time
1206 b) do the full catalog check (expensive but accurate)
1207 sizing guide (how much system is needed to back up N systems/files)
1208 consultants on using bacula in building a disaster recovery system
1209 an integration guide
1210 or how to get at fancy things that one could do with bacula
1211 logwatch code for bacula logs (or similar)
1212 linux distro inclusion of bacula (brings good and bad, but necessary)
1213 win2k/XP server capability (icky but you asked)
1214 support for Oracle database ??
1216 - Look at adding SQL server and Exchange support for Windows.
1217 - Make dev->file and dev->block_num signed integers so that -1 can
1218 be an invalid value which happens with BSR.
1219 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1220 is needed to properly specify ranges.
1221 - Add progress of files/bytes to SD and FD.
1222 - Print warning message if FileId > 4 billion
1223 - do a "messages" before the first prompt in Console
1224 - Client does not show busy during Estimate command.
1225 - Implement Console mtx commands.
1226 - Implement a Mount Command and an Unmount Command where
1227 the users could specify a system command to be performed
1228 to do the mount, after which Bacula could attempt to
1229 read the device. This is for Removeable media such as a CDROM.
1230 - Most likely, this mount command would be invoked explicitly
1231 by the user using the current Console "mount" and "unmount"
1232 commands -- the Storage Daemon would do the right thing
1233 depending on the exact nature of the device.
1234 - As with tape drives, when Bacula wanted a new removable
1235 disk mounted, it would unmount the old one, and send a message
1236 to the user, who would then use "mount" as described above
1237 once he had actually inserted the disk.
1238 - Implement dump/print label to UA
1239 - Spool to disk only when the tape is full, then when a tape is hung move
1241 - bextract is sending everything to the log file ****FIXME****
1242 - Allow multiple Storage specifications (or multiple names on
1243 a single Storage specification) in the Job record. Thus a job
1244 can be backed up to a number of storage devices.
1245 - Implement some way for the File daemon to contact the Director
1246 to start a job or pass its DHCP obtained IP number.
1247 - Implement a query tape prompt/replace feature for a console
1248 - Copy console @ code to gnome2-console
1249 - Make tree walk routines like cd, ls, ... more user friendly
1250 by handling spaces better.
1251 - Make sure that Bacula rechecks the tape after the 20 min wait.
1252 - Set IO_NOWAIT on Bacula TCP/IP packets.
1253 - Try doing a raw partition backup and restore by mounting a
1255 - From Lars Kellers:
1256 Yes, it would allow to highly automatic the request for new tapes. If a
1257 tape is empty, bacula reads the barcodes (native or simulated), and if
1258 an unused tape is found, it runs the label command with all the
1259 necessary parameters.
1261 By the way can bacula automatically "move" an empty/purged volume say
1262 in the "short" pool to the "long" pool if this pool runs out of volume
1264 - What to do about "list files job=xxx".
1265 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1266 file descriptor leak in Bacula.
1267 - Implement WrapCounters in Counters.
1268 - Add heartbeat from FD to SD if hb interval expires.
1269 - Can we dynamically change FileSets?
1270 - If pool specified to label command and Label Format is specified,
1271 automatically generate the Volume name.
1272 - Why can't SQL do the filename sort for restore?
1273 - Add ExhautiveRestoreSearch
1274 - Look at the possibility of loading only the necessary
1275 data into the restore tree (i.e. do it one directory at a
1276 time as the user walks through the tree).
1277 - Possibly use the hash code if the user selects all for a restore command.
1278 - Fix "restore all" to bypass building the tree.
1279 - Prohibit backing up archive device (findlib/find_one.c:128)
1280 - Implement Release Device in the Job resource to unmount a drive.
1281 - Implement Acquire Device in the Job resource to mount a drive,
1282 be sure this works with admin jobs so that the user can get
1283 prompted to insert the correct tape. Possibly some way to say to
1284 run the job but don't save the files.
1285 - Make things like list where a file is saved case independent for
1287 - Use autochanger to handle multiple devices.
1288 - Implement a Recycle command
1289 - Start working on Base jobs.
1290 - Implement UnsavedFiles DB record.
1291 - From Phil Stracchino:
1292 It would probably be a per-client option, and would be called
1293 something like, say, "Automatically purge obsoleted jobs". What it
1294 would do is, when you successfully complete a Differential backup of a
1295 client, it would automatically purge all Incremental backups for that
1296 client that are rendered redundant by that Differential. Likewise,
1297 when a Full backup on a client completed, it would automatically purge
1298 all Differential and Incremental jobs obsoleted by that Full backup.
1299 This would let people minimize the number of tapes they're keeping on
1300 hand without having to master the art of retention times.
1301 - When doing a Backup send all attributes back to the Director, who
1302 would then figure out what files have been deleted.
1303 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1304 explicit permission to do so. It should also mark the tape in error
1305 if there is an error.
1306 - Cancel waiting for Client connect in SD if FD goes away.
1308 - Implement timeout in response() when it should come quickly.
1309 - Implement a Slot priority (loaded/not loaded).
1310 - Implement "vacation" Incremental only saves.
1311 - Implement create "FileSet"?
1312 - Add prefixlinks to where or not where absolute links to FD.
1313 - Issue message to mount a new tape before the rewind.
1314 - Simplified client job initiation for portables.
1315 - If SD cannot open a drive, make it periodically retry.
1316 - Add more of the config info to the tape label.
1318 - Refine SD waiting output:
1319 Device is being positioned
1320 > Device is being positioned for append
1321 > Device is being positioned to file x
1323 - Figure out some way to estimate output size and to avoid splitting
1324 a backup across two Volumes -- this could be useful for writing CDROMs
1325 where you really prefer not to have it split -- not serious.
1326 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1327 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1328 actual data on the Volume and compare it.
1329 - Implement Bacula plugins -- design API
1330 - Make bcopy read through bad tape records.
1331 - Program files (i.e. execute a program to read/write files).
1332 Pass read date of last backup, size of file last time.
1333 - Add Signature type to File DB record.
1334 - CD into subdirectory when open()ing files for backup to
1335 speed up things. Test with testfind().
1336 - Priority job to go to top of list.
1337 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1338 - Implement some way for the Console to dynamically create a job.
1339 - Solaris -I on tar for include list
1340 - Need a verbose mode in restore, perhaps to bsr.
1341 - bscan without -v is too quiet -- perhaps show jobs.
1342 - Add code to reject whole blocks if not wanted on restore.
1343 - Check if we can increase Bacula FD priorty in Win2000
1344 - Make sure the MaxVolFiles is fully implemented in SD
1345 - Check if both CatalogFiles and UseCatalog are set to SD.
1346 - Possibly add email to Watchdog if drive is unmounted too
1347 long and a job is waiting on the drive.
1348 - After unmount, if restore job started, ask to mount.
1349 - Add UA rc and history files.
1350 - put termcap (used by console) in ./configure and
1351 allow -with-termcap-dir.
1352 - Fix Autoprune for Volumes to respect need for full save.
1353 - Compare tape to Client files (attributes, or attributes and data)
1354 - Make all database Ids 64 bit.
1355 - Allow console commands to detach or run in background.
1356 - Add SD message variables to control operator wait time
1357 - Maximum Operator Wait
1358 - Minimum Message Interval
1359 - Maximum Message Interval
1360 - Send Operator message when cannot read tape label.
1361 - Verify level=Volume (scan only), level=Data (compare of data to file).
1362 Verify level=Catalog, level=InitCatalog
1364 - Add keyword search to show command in Console.
1365 - Events : tape has more than xxx bytes.
1366 - Complete code in Bacula Resources -- this will permit
1367 reading a new config file at any time.
1368 - Handle ctl-c in Console
1369 - Implement script driven addition of File daemon to config files.
1370 - Think about how to make Bacula work better with File (non-tape) archives.
1371 - Write Unix emulator for Windows.
1372 - Put memory utilization in Status output of each daemon
1373 if full status requested or if some level of debug on.
1374 - Make database type selectable by .conf files i.e. at runtime
1375 - Set flag for uname -a. Add to Volume label.
1376 - Restore files modified after date
1377 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1378 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1379 - Timout a job or terminate if link goes down, or reopen link and query.
1380 - Concept of precious tapes (cannot be reused).
1381 - Make bcopy copy with a single tape drive.
1382 - Permit changing ownership during restore.

1396 - Autolabel should be specified by DIR instead of SD.
1398 - Add media capacity
1399 - AutoScan (check checksum of tape)
1400 - Format command = "format /dev/nst0"
1404 - Seek resolution (usually corresponds to buffer size)
1405 - EODErrorCode=ENOSPC or code
1406 - Partial Read error code
1407 - Partial write error code
1408 - Nonformatted read error
1409 - Nonformatted write error
1410 - WriteProtected error
1414 - IgnoreCloseErrors=yes
1424 - FD sends unsaved file list to Director at end of job (see
1426 - File daemon should build list of files skipped, and then
1427 at end of save retry and report any errors.
1428 - Write a Storage daemon that uses pipes and
1429 standard Unix programs to write to the tape.
1431 - Need something that monitors the JCR queue and
1432 times out jobs by asking the deamons where they are.
1433 - Enhance Jmsg code to permit buffering and saving to disk.
1434 - device driver = "xxxx" for drives.
1435 - Verify from Volume
1436 - Ensure that /dev/null works
1437 - Need report class for messages. Perhaps
1438 report resource where report=group of messages
1439 - enhance scan_attrib and rename scan_jobtype, and
1440 fill in code for "since" option
1441 - Director needs a time after which the report status is sent
1442 anyway -- or better yet, a retry time for the job.
1443 - Don't reschedule a job if previous incarnation is still running.
1444 - Some way to automatically backup everything is needed????
1445 - Need a structure for pending actions:
1447 - termination status (part of buffered msgs?)
1449 Read, Write, Clean, Delete
1450 - Login to Bacula; Bacula users with different permissions:
1451 owner, group, user, quotas
1452 - Store info on each file system type (probably in the job header on tape.
1453 This could be the output of df; or perhaps some sort of /etc/mtab record.
1455 ========= ideas ===============
1456 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1457 To: <kern@sibbald.com>
1458 Subject: RE: [Bacula-users] future large programming jobs
1459 Date: Thu, 26 Feb 2004 11:34:54 -0600
1461 I noticed the subject thread and thought I would offer the following
1462 merely as sources of ideas, i.e. something to think about, not even as
1463 strong as a request. In my former life (before retiring) I often
1464 dealt with backups and storage management issues/products as a
1465 developer and as a consultant. I am currently migrating my personal
1466 network from amanda to bacula specifically because of the ability to
1467 cross media boundaries during storing backups.
1468 Are you familiar with the commercial product called ADSM (I think IBM
1469 now sells it under the Tivoli label)? It has a couple of interesting
1470 ideas that may apply to the following topics.
1472 1. Migration: Consider that when you need to restore a system, there
1473 may be pressure to hurry. If all the information for a single client
1474 can eventually end up on the same media (and in chronological order),
1475 the restore is facillitated by not having to search past information
1476 from other clients. ADSM has the concept of "client affinity" that
1477 may be associated with it's storage pools. It seems to me that this
1478 concept (as an optional feature) might fit in your architecture for
1481 ADSM also has the concept of defining one or more storage pools as
1482 "copy pools" (almost mirrors, but only in the sense of contents).
1483 These pools provide the ability to have duplicte data stored both
1484 onsite and offsite. The copy process can be scheduled to be handled
1485 by their storage manager during periods when there is no backup
1486 activity. Again, the migration process might be a place to consider
1487 implementing something like this.
1490 > It strikes me that it would be very nice to be able to do things
1492 > have the Job(s) backing up the machines run, and once they have all

1498 > mechanism described below would probably make it very easy.
1500 This is the goal. In the first step (before events), you simply
1502 the Migration to tape later.
1504 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1505 the database. Once a file (unique by path and metadata such as dates,
1506 size, ownership, etc.) is in a copy pool, no more copies are made. In
1507 other words, when you start ADSM, it begins like your concept of a
1508 base job. After that it is in the "incremental" mode. You can
1509 configure the number of "generations" of files to be retained, plus a
1510 retention date after which even old generations are purged. The
1511 database tracks the contents of media and projects the percentage of
1512 each volume that is valid. When the valid content of a volume drops
1513 below a configured percentage, the valid data are migrated to another
1514 volume and the old volume is marked as empty. Note, this requires
1515 ADSM to have an idea of the contents of a client, i.e. marking the
1516 database when an existing file was deleted, but this would solve your
1517 issue of restoring a client without restoring deleted files.
1519 This is pretty far from what bacula now does, but if you are going to
1520 rip things up for Base jobs,.....
1521 Also, the benefits of this are huge for very large shops, especially
1522 with media robots, but are a pain for shops with manual media
1526 > Base jobs sound pretty useful, but I'm not dying for them.
1528 Nobody is dying for them, but when you see what it does, you will die
1531 3. Restoring deleted files: Since I think my comments in (2) above
1532 have low probability of implementation, I'll also suggest that you
1533 could approach the issue of deleted files by a mechanism of having the
1534 fd report to the dir, a list of all files on the client for every
1535 backup job. The dir could note in the database entry for each file
1536 the date that the file was seen. Then if a restore as of date X takes
1537 place, only files that exist from before X until after X would be
1538 restored. Probably the major cost here is the extra date container in
1539 each row of the files table.
1541 Thanks for "listening". I hope some of this helps. If you want to
1542 contact me, please send me an email - I read some but not all of the
1543 mailing list traffic and might miss a reply there.
1545 Please accept my compliments for bacula. It is doing a great job for
1546 me!! I sympathize with you in the need to wrestle with excelence in
1547 execution vs. excelence in feature inclusion.
1552 ==============================
1555 - Design at hierarchial storage for Bacula. Migration and Clone.
1556 - Implement FSM (File System Modules).
1557 - Audit M_ error codes to ensure they are correct and consistent.
1558 - Add variable break characters to lex analyzer.
1559 Either a bit mask or a string of chars so that
1560 the caller can change the break characters.
1561 - Make a single T_BREAK to replace T_COMMA, etc.
1562 - Ensure that File daemon and Storage daemon can
1563 continue a save if the Director goes down (this
1564 is NOT currently the case). Must detect socket error,
1565 buffer messages for later.
1566 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1567 - Add ability to backup to two Storage devices (two SD sessions) at
1568 the same time -- e.g. onsite, offsite.
1569 - Add the ability to consolidate old backup sets (basically do a restore
1570 to tape and appropriately update the catalog). Compress Volume sets.
1571 Might need to spool via file is only one drive is available.
1572 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1573 someway to do so with every volume that has less than x% valid
1577 Migration: Move a backup from one Volume to another
1578 Clone: Copy a backup -- two Volumes
1581 ======================================================
1583 It is somewhat like a Full save becomes an incremental since
1584 the Base job (or jobs) plus other non-base files.
1586 - A Base backup is same as Full backup, just different type.
1587 - New BaseFiles table that contains:
1589 BaseJobId - Base JobId referenced for this FileId (needed ???)
1590 JobId - JobId currently running
1591 FileId - File not backed up, exists in Base Job
1592 FileIndex - FileIndex from Base Job.
1593 i.e. for each base file that exists but is not saved because
1594 it has not changed, the File daemon sends the JobId, BaseId,
1595 FileId, FileIndex back to the Director who creates the DB entry.
1596 - To initiate a Base save, the Director sends the FD
1597 the FileId, and full filename for each file in the Base.
1598 - When the FD finds a Base file, he requests the Director to
1599 send him the full File entry (stat packet plus MD5), or
1600 conversely, the FD sends it to the Director and the Director
1601 says yes or no. This can be quite rapid if the FileId is kept
1602 by the FD for each Base Filename.
1603 - It is probably better to have the comparison done by the FD
1604 despite the fact that the File entry must be sent across the
1606 - An alternative would be to send the FD the whole File entry
1607 from the start. The disadvantage is that it requires a lot of
1608 space. The advantage is that it requires less communications
1610 - The Job record must be updated to indicate that one or more
1612 - At end of Job, FD returns:
1613 1. Count of base files/bytes not written to tape (i.e. matches)
1614 2. Count of base file that were saved i.e. had changed.
1615 - No tape record would be written for a Base file that matches, in the
1616 same way that no tape record is written for Incremental jobs where
1617 the file is not saved because it is unchanged.
1618 - On a restore, all the Base file records must explicitly be
1619 found from the BaseFile tape. I.e. for each Full save that is marked
1620 to have one or more Base Jobs, search the BaseFile for all occurrences
1622 - An optimization might be to make the BaseFile have:
1628 This would avoid the need to explicitly fetch each File record for
1629 the Base job. The Base Job record will be fetched to get the
1630 VolSessionId and VolSessionTime.
1631 =========================================================
1634 ==========================================================
1636 For each Incremental job that is run, there may be files that
1637 were found but not saved because they were locked (this applies
1638 only to Windows). Such a system could send back to the Director
1639 a list of Unsaved files.
1641 - New UnSavedFiles table that contains:
1645 - Then in the next Incremental job, the list of Unsaved Files will be
1646 feed to the FD, who will ensure that they are explicitly chosen even
1647 if standard date/time check would not have selected them.
1648 =============================================================

1689 (just to verify it remembers where it came from, however it can be
1690 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1692 There needs to be a table of drive # to devices somewhere - If there are
1693 multiple changers or drives there may not be a 1:1 correspondance between
1694 changer drive number and system device name - and depending on the way the
1695 drives are hooked up to scsi busses, they may not be linearly numbered
1696 from an offset point either.something like
1698 Autochanger drives = 2
1699 Autochanger drive 0 = /dev/nst1
1700 Autochanger drive 1 = /dev/nst2
1701 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1702 times, not just for multidrive changers. For a 1 drive changer, that's
1708 MTX's manpage (1.2.15):
1709 unload [<slotnum>] [ <drivenum> ]
1710 Unloads media from drive <drivenum> into slot
1711 <slotnum>. If <drivenum> is omitted, defaults to
1712 drive 0 (as do all commands). If <slotnum> is
1713 omitted, defaults to the slot that the drive was
1714 loaded from. Note that there's currently no way
1715 to say 'unload drive 1's media to the slot it
1716 came from', other than to explicitly use that
1717 slot number as the destination.AB

1755 Handling removable disks
1757 From: Karl Cunningham <karlc@keckec.com>
1759 My backups are only to hard disk these days, in removable bays. This is my
1760 idea of how a backup to hard disk would work more smoothly. Some of these
1761 things Bacula does already, but I mention them for completeness. If others
1762 have better ways to do this, I'd like to hear about it.
1764 1. Accommodate several disks, rotated similar to how tapes are. Identified
1765 by partition volume ID or perhaps by the name of a subdirectory.
1766 2. Abort & notify the admin if the wrong disk is in the bay.
1767 3. Write backups to different subdirectories for each machine to be backed
1769 4. Volumes (files) get created as needed in the proper subdirectory, one
1771 5. When a disk is recycled, remove or zero all old backup files. This is
1772 important as the disk being recycled may be close to full. This may be
1773 better done manually since the backup files for many machines may be
1774 scattered in many subdirectories.
1779 - Why the heck doesn't bacula drop root priviledges before connecting to
1781 - Look at using posix_fadvise(2) for backups -- see bug #751.
1782 Possibly add the code at findlib/bfile.c:795
1783 /* TCP socket options */
1784 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1785 - Fix bnet_connect() code to set a timer and to use time to
1787 - Implement 4th argument to make_catalog_backup that passes hostname.
1788 - Test FIFO backup/restore -- make regression
1789 - Please mount volume "xxx" on Storage device ... should also list
1790 Pool and MediaType in case user needs to create a new volume.
1791 - On restore add Restore Client, Original Client.

1800 - Check if gnome-console works with TLS.
1801 - the director seg faulted when I omitted the pool directive from a
1802 job resource. I was experimenting and thought it redundant that I had
1803 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1804 apparently not. This happened when I removed the pool directive and
1805 started the director.
1806 - Add Where: client:/.... to restore job report.
1807 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1808 does the right thing.
1809 - FD-SD quick disconnect
1810 - Building the in memory restore tree is slow.
