15 if the system "sees" a long path once, it seems to forget it's
16 working drive (e.g. c:\), which will lead to a problem during
17 the next job (create bootstrap file will fail). Here is the

93 - Eliminate: /var is a different filesystem. Will not descend from / into /var
94 - Separate Files and Directories in catalog
95 - Create FileVersions table
96 - Look at rsysnc for incremental updates and dedupping
97 - Add MD5 or SHA1 check in SD for data validation
98 - modify pruning to keep a fixed number of versions of a file,
100 - finish implementation of fdcalled -- see ua_run.c:105
101 - Fix problem in postgresql.c in my_postgresql_query, where the
102 generation of the error message doesn't differentiate result==NULL
103 and a bad status from that result. Not only that, the result is
104 cleared on a bail_out without having generated the error message.
106 - Implement SDErrors (must return from SD)

122 now prints warnings too often.
123 - Ensure that each device in an Autochanger has a different
125 - Add Catalog = to Pool resource so that pools will exist
126 in only one catalog -- currently Pools are "global".
127 - Look at sg_logs -a /dev/sg0 for getting soft errors.
128 - btape "test" command with Offline on Unmount = yes
130 This test is essential to Bacula.
132 I'm going to write one record in file 0,

149 - Why doesn't @"xxx abc" work in a conf file?
150 - Figure out some way to "automatically" backup conf changes.
151 - Add the OS version back to the Win32 client info.
152 - Restarted jobs have a NULL in the from field.
153 - Modify SD status command to indicate when the SD is writing
154 to a DVD (the device is not open -- see bug #732).
155 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
156 and possibly changing the blobs into varchar.
157 - Ensure that the SD re-reads the Media record if the JobFiles
158 does not match -- it may have been updated by another job.
159 - Look at moving the Storage directive from the Job to the
160 Pool in the default conf files.
162 - Test Volume compatibility between machine architectures
163 - Encryption documentation

178 - Copy Pool = xx, yyy (or multiple lines).
180 - Allow pool selection during restore.
182 - Average tape size from Eric
183 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg

194 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
195 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
199 - Add doc for bweb -- especially Installation
201 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
203 - Despool attributes in separate thread
206 - Check why restore repeatedly sends Rechdrs between
207 each data chunk -- according to James Harper 9Jan07.
210 - Full at least once a month, ...
211 - Cancel Inc if Diff/Full running
212 - More intelligent re-run

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

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

354 order by Path.Path ASC;
356 - Look into using Dart for testing

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

536 - http://www.dwheeler.com/essays/commercial-floss.html
537 - Add VolumeLock to prevent all but lock holder (SD) from updating
538 the Volume data (with the exception of VolumeState).
539 - The btape fill command does not seem to use the Autochanger
540 - Make Windows installer default to system disk drive.
541 - Look at using ioctl(FIOBMAP, ...) on Linux, and
542 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
543 Win32 for sparse files.

561 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
562 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
563 - Implement a mode that says when a hard read error is
564 encountered, read many times (as it currently does), and if the
565 block cannot be read, skip to the next block, and try again. If
566 that fails, skip to the next file and try again, ...
568 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
569 insert into LevelType (LevelType,LevelTypeLong) values
573 - Show files/second in client status output.
574 - Add a recursive mark command (rmark) to restore.
575 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
576 of the same level and does not permit multiple simultaneous
577 running of that Job (i.e. lets any previous invocation finish
578 before doing Interval testing).
579 - Look at simplifying File exclusions.
580 - New directive "Delete purged Volumes"
581 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
582 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
583 see if it become stable and I just have to supervise
585 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
586 PoolId, and when it is empty remove it.
587 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
589 - Allow Check Labels to be used with Bacula labels.

591 failed backup as a sort of "base" job.
593 - Email to the user when the tape is about to need changing x
594 days before it needs changing.
595 - Command to show next tape that will be used for a job even
596 if the job is not scheduled.
597 - From: Arunav Mandal <amandal@trolltech.com>
598 1. When jobs are running and bacula for some reason crashes or if I do a
599 restart it remembers and jobs it was running before it crashed or restarted
600 as of now I loose all jobs if I restart it.
602 2. When spooling and in the midway if client is disconnected for instance a
603 laptop bacula completely discard the spool. It will be nice if it can write
604 that spool to tape so there will be some backups for that client if not all.
606 3. We have around 150 clients machines it will be nice to have a option to
607 upgrade all the client machines bacula version automatically.
609 4. Atleast one connection should be reserved for the bconsole so at heavy load
610 I should connect to the director via bconsole which at sometimes I can't
612 5. Another most important feature that is missing, say at 10am I manually
613 started backup of client abc and it was a full backup since client abc has
614 no backup history and at 10.30am bacula again automatically started backup of
615 client abc as that was in the schedule. So now we have 2 multiple Full
616 backups of the same client and if we again try to start a full backup of
617 client backup abc bacula won't complain. That should be fixed.
619 - Fix bpipe.c so that it does not modify results pointer.
620 ***FIXME*** calling sequence should be changed.
621 - For Windows disaster recovery see http://unattended.sf.net/
622 - regardless of the retention period, Bacula will not prune the
623 last Full, Diff, or Inc File data until a month after the
624 retention period for the last Full backup that was done.
625 - update volume=xxx --- add status=Full
626 - Remove old spool files on startup.
627 - Exclude SD spool/working directory.
628 - Refuse to prune last valid Full backup. Same goes for Catalog.
630 - Make a callback when Rerun failed levels is called.
631 - Give Python program access to Scheduled jobs.
632 - Add setting Volume State via Python.
633 - Python script to save with Python, not save, save with Bacula.
634 - Python script to do backup.
636 - Change the Priority, Client, Storage, JobStatus (error)
637 at the start of a job.
638 - Why is SpoolDirectory = /home/bacula/spool; not reported
639 as an error when writing a DVD?
640 - Make bootstrap file handle multiple MediaTypes (SD)
641 - Remove all old Device resource code in Dir and code to pass it
642 back in SD -- better, rework it to pass back device statistics.
643 - Check locking of resources -- be sure to lock devices where previously
644 resources were locked.
645 - The last part is left in the spool dir.
648 - In restore don't compare byte count on a raw device -- directory
649 entry does not contain bytes.
653 MA = (last_MA * 3 + rate) / 4
654 rate = (bytes - last_bytes) / (runtime - last_runtime)
655 - Max Vols limit in Pool off by one?
656 - Implement Files/Bytes,... stats for restore job.
657 - Implement Total Bytes Written, ... for restore job.
658 - Despool attributes simultaneously with data in a separate
659 thread, rejoined at end of data spooling.
660 - 7. Implement new Console commands to allow offlining/reserving drives,
661 and possibly manipulating the autochanger (much asked for).
662 - Add start/end date editing in messages (%t %T, %e?) ...
663 - Add ClientDefs similar to JobDefs.
664 - Print more info when bextract -p accepts a bad block.
665 - Fix FD JobType to be set before RunBeforeJob in FD.
666 - Look at adding full Volume and Pool information to a Volume
667 label so that bscan can get *all* the info.
668 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
669 and there is only one volume in the pool, refuse to do it -- otherwise
670 he fills the Volume, then immediately starts reusing it.
671 - Implement copies and stripes.
672 - Add history file to console.
673 - Each file on tape creates a JobMedia record. Peter has 4 million
674 files spread over 10000 tape files and four tapes. A restore takes
675 16 hours to build the restore list.
676 - Add and option to check if the file size changed during backup.
677 - Make sure SD deletes spool files on error exit.
678 - Delete old spool files when SD starts.
679 - When labeling tapes, if you enter 000026, Bacula uses
680 the tape index rather than the Volume name 000026.
681 - Add offline tape command to Bacula console.
683 Enter MediaId or Volume name: 32
684 Enter new Volume name: DLT-20Dec04
685 Automatically selected Pool: Default
686 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

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

843 === From Carsten Menke <bootsy52@gmx.net>
845 Following is a list of what I think in the situations where I'm faced with,
846 could be a usefull enhancement to bacula, which I'm certain other users will
847 benefit from as well.
849 1. NextJob/NextJobs Directive within a Job Resource in the form of
850 NextJobs = job1,job2.
853 I currently solved the problem with running multiple jobs each after each
854 by setting the Max Wait Time for a job to 8 hours, and give
855 the jobs different Priorities. However, there scenarios where
856 1 Job is directly depending on another job, so if the former job fails,
857 the job after it needn't to be run
858 while maybe other jobs should run despite of that
861 A Backup Job and a Verify job, if the backup job fails there is no need to run
862 the verify job, as the backup job already failed. However, one may like
863 to backup the Catalog to disk despite of that the main backup job failed.
866 I see that this is related to the Event Handlers which are on the ToDo
867 list, also it is maybe a good idea to check for the return value and
868 execute different actions based on the return value
871 3. offline capability to bconsole
874 Currently I use a script which I execute within the last Job via the
875 RunAfterJob Directive, to release and eject the tape.
876 So I have to call bconsole "release=Storage-Name" and afterwards
877 mt -f /dev/nst0 eject to get the tape out.
879 If I have multiple Storage Devices, than these may not be /dev/nst0 and
880 I have to modify the script or call it with parameters etc.
881 This would actually not be needed, as everything is already defined
882 in bacula-sd.conf and if I can invoke bconsole with the
883 storage name via $1 in the script than I'm done and information is
886 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
890 For the reason mentioned in 3. to have the ability to call a
891 script with /scripts/foobar %s and in the script use $1
892 to pass the Storage Name to bconsole
894 5. Setting Volume State within a Job Resource
897 Instead of using "Maximum Volume Jobs" in the Pool Resource,
898 I would have the possibilty to define
899 in a Job Resource that after this certain job is run, the Volume State
900 should be set to "Volume State = Used", this give more flexibility (IMHO).
902 6. Localization of Bacula Messages
905 Unfortunatley many,many people I work with don't speak english very well.
906 So if at least the Reporting messages would be localized then they
907 would understand that they have to change the tape,etc. etc.
909 I volunteer to do the german translations, and if I can convince my wife also
910 french and Morre (western african language).
912 7. OK, this is evil, probably bound to security risks and maybe not possible
913 due to the design of bacula.
915 Implementation of Backtics ( `command` ) for shell comand execution to
916 the "Label Format" Directive.
920 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
921 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
922 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
923 the localized name for the day of the week appended to the
924 format string. Then I have the tape labeled automatically with weekday
925 name in the correct language.
927 - Yes, that is surely the case. I probably should turn those into Warning
928 errors. In addition, you just made me think that it might not be bad to
929 add an option to check the file size after backing up the file and
930 report if it changes. This would be done as an option because it would
933 Kern, good idea. If you do do that, mention in the output: file
934 shrunk, or file expanded, just to make it obvious to the user
935 (without having to the refer to file size), just how the file size
938 Would this option be for all file, or just one file? Or a fileset?
939 - Make output from status use html table tags for nicely
940 presenting in a browser.
941 - Can one write tapes faster with 8192 byte block sizes?
942 - Document security problems with the same password for everyone in
943 rpm and Win32 releases.
944 - Browse generations of files.
945 - I've seen an error when my catalog's File table fills up. I
946 then have to recreate the File table with a larger maximum row
947 size. Relevant information is at
948 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
949 "Installing and Configuring MySQL" chapter should talk a bit
950 about this potential problem, and recommend a solution.
951 - For Solaris must use POSIX awk.
952 - Want speed of writing to tape while despooling.
953 - Supported autochanger:
961 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
962 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
963 - Add regex from http://www.pcre.org to Bacula for Win32.
964 - Use only shell tools no make in CDROM package.
965 - Include within include does it work?
966 - Implement a Pool of type Cleaning?
967 - Implement VolReadTime and VolWriteTime in SD
968 - Modify Backing up Your Database to include a bootstrap file.
969 - Think about making certain database errors fatal.
970 - Look at correcting the time jump in the scheduler for daylight
971 savings time changes.
972 - Add a "real" timer to network connections.
973 - Promote to Full = Time period
974 - Check dates entered by user for correctness (month/day/... ranges)
975 - Compress restore Volume listing by date and first file.
976 - Look at patches/bacula_db.b2z postgresql that loops during restore.
978 - Perhaps add read/write programs and/or plugins to FileSets.
979 - How to handle backing up portables ...
980 - Add some sort of guaranteed Interval for upgrading jobs.
981 - Can we write the state file after every job terminates? On Win32
982 the system crashes and the state file is not updated.
985 Documentation to do: (any release a little bit at a time)
986 - Doc to do unmount before removing magazine.
987 - Alternative to static linking "ldd prog" save all binaries listed,
988 restore them and point LD_LIBRARY_PATH to them.
989 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
990 - Document query file format.
991 - Add more documentation for bsr files.
992 - Document problems with Verify and pruning.
993 - Document how to use multiple databases.
994 - VXA drives have a "cleaning required"
995 indicator, but Exabyte recommends preventive cleaning after every 75
998 In this context, it should be noted that Exabyte has a command-line
999 vxatool utility available for free download. (The current version is
1000 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
1001 test the drive, unload tapes, change drive settings, flash new firmware,
1003 Of particular interest in this context is that vxatool <device> -i will
1004 report, among other details, the time since last cleaning in tape motion
1005 minutes. This information can be retrieved (and settings changed, for
1006 that matter) through the generic-SCSI device even when Bacula has the
1007 regular tape device locked. (Needless to say, I don't recommend
1008 changing tape settings while a job is running.)
1009 - Lookup HP cleaning recommendations.
1010 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
1011 - Document doing table repair
1014 ===================================
1015 - Add macro expansions in JobDefs.
1016 Run Before Job = "SomeFile %{Level} %{Client}"
1017 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
1018 - Use non-blocking network I/O but if no data is available, use
1020 - Use gather write() for network I/O.
1021 - Autorestart on crash.
1022 - Add bandwidth limiting.
1023 - Add acks every once and a while from the SD to keep
1024 the line from timing out.
1025 - When an error in input occurs and conio beeps, you can back
1026 up through the prompt.
1027 - Detect fixed tape block mode during positioning by looking at
1028 block numbers in btape "test". Possibly adjust in Bacula.
1029 - Fix list volumes to output volume retention in some other
1030 units, perhaps via a directive.
1031 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
1032 with multiple priorities.
1033 - If you use restore replace=never, the directory attributes for
1034 non-existent directories will not be restored properly.
1036 - see lzma401.zip in others directory for new compression
1038 - Allow the user to select JobType for manual pruning/purging.
1039 - bscan does not put first of two volumes back with all info in
1041 - Implement the FreeBSD nodump flag in chflags.
1042 - Figure out how to make named console messages go only to that
1043 console and to the non-restricted console (new console class?).
1044 - Make restricted console prompt for password if *ask* is set or
1045 perhaps if password is undefined.
1046 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1049 ==== from Marc Schoechlin
1050 - the help-command should be more verbose
1051 (it should explain the paramters of the different
1053 -> its time-comsuming to consult the manual anytime
1054 you need a special parameter
1055 -> maybe its more easy to maintain this, if the
1056 descriptions of that commands are outsourced to
1058 - the cd-command should allow complete paths
1059 i.e. cd /foo/bar/foo/bar
1060 -> if a customer mails me the path to a certain file,
1061 its faster to enter the specified directory
1062 - if the password is not configured in bconsole.conf
1063 you should be asked for it.
1064 -> sometimes you like to do restore on a customer-machine
1065 which shouldnt know the password for bacula.
1066 -> adding the password to the file favours admins
1067 to forget to remove the password after usage
1069 the protection of that file is less important
1070 - long-listed-output of commands should be scrollable
1071 like the unix more/less-command does
1072 -> if someone runs 200 and more machines, the lists could
1073 be a little long and complex
1074 - command-output should be shown column by column
1075 to reduce scrolling and to increase clarity
1077 - lsmark should list the selected files with full
1079 - wildcards for selecting and file and directories would be nice
1080 - any actions should be interuptable with STRG+C
1081 - command-expansion would be pretty cool
1083 - When the replace Never option is set, new directory permissions
1084 are not restored. See bug 213. To fix this requires creating a
1085 list of newly restored directories so that those directory
1086 permissions *can* be restored.
1087 - Add prune all command
1088 - Document fact that purge can destroy a part of a restore by purging
1089 one volume while others remain valid -- perhaps mark Jobs.
1090 - Add multiple-media-types.txt
1091 - look at mxt-changer.html
1092 - Make ? do a help command (no return needed).
1093 - Implement restore directory.
1094 - Document streams and how to implement them.
1095 - Try not to re-backup a file if a new hard link is added.
1096 - Add feature to backup hard links only, but not the data.
1097 - Fix stream handling to be simpler.
1098 - Add Priority and Bootstrap to Run a Job.
1099 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1101 - Remove View FileSet button from Run a Job dialog.
1102 - Handle prompt for restore job at end of Restore command.
1103 - Add display of total selected files to Restore window.
1104 - Add tree pane to left of window.
1105 - Add progress meter.
1106 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1107 - Add message to user to check for fixed block size when the forward
1108 space test fails in btape.
1109 - When unmarking a directory check if all files below are unmarked and
1110 then remove the + flag -- in the restore tree.
1111 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1112 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1113 - Revisit the question of multiple Volumes (disk) on a single device.
1114 - Add a block copy option to bcopy.
1115 - Finish work on Gnome restore GUI.
1116 - Fix "llist jobid=xx" where no fileset or client exists.
1117 - For each job type (Admin, Restore, ...) require only the really necessary
1118 fields.- Pass Director resource name as an option to the Console.
1119 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1120 - Add a .list all files in the restore tree (probably also a list all files)
1121 Do both a long and short form.
1122 - Allow browsing the catalog to see all versions of a file (with
1123 stat data on each file).
1124 - Restore attributes of directory if replace=never set but directory
1126 - Use SHA1 on authentication if possible.
1127 - See comtest-xxx.zip for Windows code to talk to USB.
1128 - Add John's appended files:
1129 Appended = { /files/server/logs/http/*log }
1130 and such files would be treated as follows.On a FULL backup, they would
1131 be backed up like any other file.On an INCREMENTAL backup, where a
1132 previous INCREMENTAL or FULL was already in thecatalogue and the length
1133 of the file wasgreater than the length of the last backup, only thedata
1134 added since the last backup will be dumped.On an INCREMENTAL backup, if
1135 the length of the file is less than thelength of the file with the same
1136 name last backed up, the completefile is dumped.On Windows systems, with
1137 creation date of files, we can be evensmarter about this and not count
1138 entirely upon the length.On a restore, the full and all incrementals
1139 since it will beapplied in sequence to restore the file.
1140 - Check new HAVE_WIN32 open bits.
1141 - Check if the tape has moved before writing.
1142 - Handling removable disks -- see below:
1143 - Keep track of tape use time, and report when cleaning is necessary.
1144 - Add FromClient and ToClient keywords on restore command (or
1145 BackupClient RestoreClient).
1146 - Implement a JobSet, which groups any number of jobs. If the
1147 JobSet is started, all the jobs are started together.
1148 Allow Pool, Level, and Schedule overrides.
1149 - Enhance cancel to timeout BSOCK packets after a specific delay.
1150 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1151 ua_status.!!! Thanks to Alan Brown for this tip.
1152 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1153 correctly for multiple simultaneous jobs.
1154 - Correct code so that FileSet MD5 is calculated for < and | filename
1156 - Implement the Media record flag that indicates that the Volume does disk
1158 - Implement VolAddr, which is used when Volume is addressed like a disk,
1159 and form it from VolFile and VolBlock.
1160 - Make multiple restore jobs for multiple media types specifying
1161 the proper storage type.
1162 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1163 pointer (rec) to try_repositioning().
1164 - Look at extracting Win data from BackupRead.
1165 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1166 which would take precidence over the Catalog "JobRetention".
1167 - Implement Label Format in Add and Label console commands.
1168 - Possibly up network buffers to 65K. Put on variable.
1169 - Put email tape request delays on one or more variables. User wants
1170 to cancel the job after a certain time interval. Maximum Mount Wait?
1171 - Job, Client, Device, Pool, or Volume?
1172 Is it possible to make this a directive which is *optional* in multiple
1173 resources, like Level? If so, I think I'd make it an optional directive
1174 in Job, Client, and Pool, with precedence such that Job overrides Client
1175 which in turn overrides Pool.
1177 - New Storage specifications:
1178 - Want to write to multiple storage devices simultaneously
1179 - Want to write to multiple storage devices sequentially (in one job)
1180 - Want to read/write simultaneously
1181 - Key is MediaType -- it must match
1183 Passed to SD as a sort of BSR record called Storage Specification
1187 MediaType -> Next MediaType
1189 Device -> Next Device
1191 Allow multiple Storage specifications
1199 Allow Multiple Pool specifications (note, Pool currently
1201 Allow Multiple MediaType specifications in Dir conf
1202 Allow Multiple Device specifications in Dir conf
1203 Perhaps keep this in a single SSR
1204 Tie a Volume to a specific device by using a MediaType that
1205 is contained in only one device.
1206 In SD allow Device to have Multiple MediaTypes
1208 - Ideas from Jerry Scharf:
1209 First let's point out some big pluses that bacula has for this
1211 more importantly it's active. Thank you so much for that
1212 even more important, it's not flaky
1213 it has an open access catalog, opening many possibilities
1214 it's pushing toward heterogeneous systems capability
1216 Macintosh file client
1217 macs are an interesting niche, but I fear a server is a rathole
1218 working bare iron recovery for windows
1219 the option for inc/diff backups not reset on fileset revision
1220 a) use both change and inode update time against base time
1221 b) do the full catalog check (expensive but accurate)
1222 sizing guide (how much system is needed to back up N systems/files)
1223 consultants on using bacula in building a disaster recovery system
1224 an integration guide
1225 or how to get at fancy things that one could do with bacula
1226 logwatch code for bacula logs (or similar)
1227 linux distro inclusion of bacula (brings good and bad, but necessary)
1228 win2k/XP server capability (icky but you asked)
1229 support for Oracle database ??
1231 - Look at adding SQL server and Exchange support for Windows.
1232 - Make dev->file and dev->block_num signed integers so that -1 can
1233 be an invalid value which happens with BSR.
1234 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1235 is needed to properly specify ranges.
1236 - Add progress of files/bytes to SD and FD.
1237 - Print warning message if FileId > 4 billion
1238 - do a "messages" before the first prompt in Console
1239 - Client does not show busy during Estimate command.
1240 - Implement Console mtx commands.
1241 - Implement a Mount Command and an Unmount Command where
1242 the users could specify a system command to be performed
1243 to do the mount, after which Bacula could attempt to
1244 read the device. This is for Removeable media such as a CDROM.
1245 - Most likely, this mount command would be invoked explicitly
1246 by the user using the current Console "mount" and "unmount"
1247 commands -- the Storage Daemon would do the right thing
1248 depending on the exact nature of the device.
1249 - As with tape drives, when Bacula wanted a new removable
1250 disk mounted, it would unmount the old one, and send a message
1251 to the user, who would then use "mount" as described above
1252 once he had actually inserted the disk.
1253 - Implement dump/print label to UA
1254 - Spool to disk only when the tape is full, then when a tape is hung move
1256 - bextract is sending everything to the log file ****FIXME****
1257 - Allow multiple Storage specifications (or multiple names on
1258 a single Storage specification) in the Job record. Thus a job
1259 can be backed up to a number of storage devices.
1260 - Implement some way for the File daemon to contact the Director
1261 to start a job or pass its DHCP obtained IP number.
1262 - Implement a query tape prompt/replace feature for a console
1263 - Copy console @ code to gnome2-console
1264 - Make tree walk routines like cd, ls, ... more user friendly
1265 by handling spaces better.
1266 - Make sure that Bacula rechecks the tape after the 20 min wait.
1267 - Set IO_NOWAIT on Bacula TCP/IP packets.
1268 - Try doing a raw partition backup and restore by mounting a
1270 - From Lars Kellers:
1271 Yes, it would allow to highly automatic the request for new tapes. If a
1272 tape is empty, bacula reads the barcodes (native or simulated), and if
1273 an unused tape is found, it runs the label command with all the
1274 necessary parameters.
1276 By the way can bacula automatically "move" an empty/purged volume say
1277 in the "short" pool to the "long" pool if this pool runs out of volume
1279 - What to do about "list files job=xxx".
1280 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1281 file descriptor leak in Bacula.
1282 - Implement WrapCounters in Counters.
1283 - Add heartbeat from FD to SD if hb interval expires.
1284 - Can we dynamically change FileSets?
1285 - If pool specified to label command and Label Format is specified,
1286 automatically generate the Volume name.
1287 - Why can't SQL do the filename sort for restore?
1288 - Add ExhautiveRestoreSearch
1289 - Look at the possibility of loading only the necessary
1290 data into the restore tree (i.e. do it one directory at a
1291 time as the user walks through the tree).
1292 - Possibly use the hash code if the user selects all for a restore command.
1293 - Fix "restore all" to bypass building the tree.
1294 - Prohibit backing up archive device (findlib/find_one.c:128)
1295 - Implement Release Device in the Job resource to unmount a drive.
1296 - Implement Acquire Device in the Job resource to mount a drive,
1297 be sure this works with admin jobs so that the user can get
1298 prompted to insert the correct tape. Possibly some way to say to
1299 run the job but don't save the files.
1300 - Make things like list where a file is saved case independent for
1302 - Use autochanger to handle multiple devices.
1303 - Implement a Recycle command
1304 - Start working on Base jobs.
1305 - Implement UnsavedFiles DB record.
1306 - From Phil Stracchino:
1307 It would probably be a per-client option, and would be called
1308 something like, say, "Automatically purge obsoleted jobs". What it
1309 would do is, when you successfully complete a Differential backup of a
1310 client, it would automatically purge all Incremental backups for that
1311 client that are rendered redundant by that Differential. Likewise,
1312 when a Full backup on a client completed, it would automatically purge
1313 all Differential and Incremental jobs obsoleted by that Full backup.
1314 This would let people minimize the number of tapes they're keeping on
1315 hand without having to master the art of retention times.
1316 - When doing a Backup send all attributes back to the Director, who
1317 would then figure out what files have been deleted.
1318 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1319 explicit permission to do so. It should also mark the tape in error
1320 if there is an error.
1321 - Cancel waiting for Client connect in SD if FD goes away.
1323 - Implement timeout in response() when it should come quickly.
1324 - Implement a Slot priority (loaded/not loaded).
1325 - Implement "vacation" Incremental only saves.
1326 - Implement create "FileSet"?
1327 - Add prefixlinks to where or not where absolute links to FD.
1328 - Issue message to mount a new tape before the rewind.
1329 - Simplified client job initiation for portables.
1330 - If SD cannot open a drive, make it periodically retry.
1331 - Add more of the config info to the tape label.
1333 - Refine SD waiting output:
1334 Device is being positioned
1335 > Device is being positioned for append
1336 > Device is being positioned to file x
1338 - Figure out some way to estimate output size and to avoid splitting
1339 a backup across two Volumes -- this could be useful for writing CDROMs
1340 where you really prefer not to have it split -- not serious.
1341 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1342 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1343 actual data on the Volume and compare it.
1344 - Make bcopy read through bad tape records.
1345 - Program files (i.e. execute a program to read/write files).
1346 Pass read date of last backup, size of file last time.
1347 - Add Signature type to File DB record.
1348 - CD into subdirectory when open()ing files for backup to
1349 speed up things. Test with testfind().
1350 - Priority job to go to top of list.
1351 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1352 - Implement some way for the Console to dynamically create a job.
1353 - Solaris -I on tar for include list
1354 - Need a verbose mode in restore, perhaps to bsr.
1355 - bscan without -v is too quiet -- perhaps show jobs.
1356 - Add code to reject whole blocks if not wanted on restore.
1357 - Check if we can increase Bacula FD priorty in Win2000
1358 - Make sure the MaxVolFiles is fully implemented in SD
1359 - Check if both CatalogFiles and UseCatalog are set to SD.
1360 - Possibly add email to Watchdog if drive is unmounted too
1361 long and a job is waiting on the drive.
1362 - After unmount, if restore job started, ask to mount.
1363 - Add UA rc and history files.
1364 - put termcap (used by console) in ./configure and
1365 allow -with-termcap-dir.
1366 - Fix Autoprune for Volumes to respect need for full save.
1367 - Compare tape to Client files (attributes, or attributes and data)
1368 - Make all database Ids 64 bit.
1369 - Allow console commands to detach or run in background.
1370 - Add SD message variables to control operator wait time
1371 - Maximum Operator Wait
1372 - Minimum Message Interval
1373 - Maximum Message Interval
1374 - Send Operator message when cannot read tape label.
1375 - Verify level=Volume (scan only), level=Data (compare of data to file).
1376 Verify level=Catalog, level=InitCatalog
1378 - Add keyword search to show command in Console.
1379 - Events : tape has more than xxx bytes.
1380 - Complete code in Bacula Resources -- this will permit
1381 reading a new config file at any time.
1382 - Handle ctl-c in Console
1383 - Implement script driven addition of File daemon to config files.
1384 - Think about how to make Bacula work better with File (non-tape) archives.
1385 - Write Unix emulator for Windows.
1386 - Put memory utilization in Status output of each daemon
1387 if full status requested or if some level of debug on.
1388 - Make database type selectable by .conf files i.e. at runtime
1389 - Set flag for uname -a. Add to Volume label.
1390 - Restore files modified after date
1391 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1392 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1393 - Timout a job or terminate if link goes down, or reopen link and query.
1394 - Concept of precious tapes (cannot be reused).
1395 - Make bcopy copy with a single tape drive.
1396 - Permit changing ownership during restore.

1410 - Autolabel should be specified by DIR instead of SD.
1412 - Add media capacity
1413 - AutoScan (check checksum of tape)
1414 - Format command = "format /dev/nst0"
1418 - Seek resolution (usually corresponds to buffer size)
1419 - EODErrorCode=ENOSPC or code
1420 - Partial Read error code
1421 - Partial write error code
1422 - Nonformatted read error
1423 - Nonformatted write error
1424 - WriteProtected error
1428 - IgnoreCloseErrors=yes
1438 - FD sends unsaved file list to Director at end of job (see
1440 - File daemon should build list of files skipped, and then
1441 at end of save retry and report any errors.
1442 - Write a Storage daemon that uses pipes and
1443 standard Unix programs to write to the tape.
1445 - Need something that monitors the JCR queue and
1446 times out jobs by asking the deamons where they are.
1447 - Enhance Jmsg code to permit buffering and saving to disk.
1448 - device driver = "xxxx" for drives.
1449 - Verify from Volume
1450 - Ensure that /dev/null works
1451 - Need report class for messages. Perhaps
1452 report resource where report=group of messages
1453 - enhance scan_attrib and rename scan_jobtype, and
1454 fill in code for "since" option
1455 - Director needs a time after which the report status is sent
1456 anyway -- or better yet, a retry time for the job.
1457 - Don't reschedule a job if previous incarnation is still running.
1458 - Some way to automatically backup everything is needed????
1459 - Need a structure for pending actions:
1461 - termination status (part of buffered msgs?)
1463 Read, Write, Clean, Delete
1464 - Login to Bacula; Bacula users with different permissions:
1465 owner, group, user, quotas
1466 - Store info on each file system type (probably in the job header on tape.
1467 This could be the output of df; or perhaps some sort of /etc/mtab record.
1469 ========= ideas ===============
1470 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1471 To: <kern@sibbald.com>
1472 Subject: RE: [Bacula-users] future large programming jobs
1473 Date: Thu, 26 Feb 2004 11:34:54 -0600
1475 I noticed the subject thread and thought I would offer the following
1476 merely as sources of ideas, i.e. something to think about, not even as
1477 strong as a request. In my former life (before retiring) I often
1478 dealt with backups and storage management issues/products as a
1479 developer and as a consultant. I am currently migrating my personal
1480 network from amanda to bacula specifically because of the ability to
1481 cross media boundaries during storing backups.
1482 Are you familiar with the commercial product called ADSM (I think IBM
1483 now sells it under the Tivoli label)? It has a couple of interesting
1484 ideas that may apply to the following topics.
1486 1. Migration: Consider that when you need to restore a system, there
1487 may be pressure to hurry. If all the information for a single client
1488 can eventually end up on the same media (and in chronological order),
1489 the restore is facillitated by not having to search past information
1490 from other clients. ADSM has the concept of "client affinity" that
1491 may be associated with it's storage pools. It seems to me that this
1492 concept (as an optional feature) might fit in your architecture for
1495 ADSM also has the concept of defining one or more storage pools as
1496 "copy pools" (almost mirrors, but only in the sense of contents).
1497 These pools provide the ability to have duplicte data stored both
1498 onsite and offsite. The copy process can be scheduled to be handled
1499 by their storage manager during periods when there is no backup
1500 activity. Again, the migration process might be a place to consider
1501 implementing something like this.
1504 > It strikes me that it would be very nice to be able to do things
1506 > have the Job(s) backing up the machines run, and once they have all

1512 > mechanism described below would probably make it very easy.
1514 This is the goal. In the first step (before events), you simply
1516 the Migration to tape later.
1518 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1519 the database. Once a file (unique by path and metadata such as dates,
1520 size, ownership, etc.) is in a copy pool, no more copies are made. In
1521 other words, when you start ADSM, it begins like your concept of a
1522 base job. After that it is in the "incremental" mode. You can
1523 configure the number of "generations" of files to be retained, plus a
1524 retention date after which even old generations are purged. The
1525 database tracks the contents of media and projects the percentage of
1526 each volume that is valid. When the valid content of a volume drops
1527 below a configured percentage, the valid data are migrated to another
1528 volume and the old volume is marked as empty. Note, this requires
1529 ADSM to have an idea of the contents of a client, i.e. marking the
1530 database when an existing file was deleted, but this would solve your
1531 issue of restoring a client without restoring deleted files.
1533 This is pretty far from what bacula now does, but if you are going to
1534 rip things up for Base jobs,.....
1535 Also, the benefits of this are huge for very large shops, especially
1536 with media robots, but are a pain for shops with manual media
1540 > Base jobs sound pretty useful, but I'm not dying for them.
1542 Nobody is dying for them, but when you see what it does, you will die
1545 3. Restoring deleted files: Since I think my comments in (2) above
1546 have low probability of implementation, I'll also suggest that you
1547 could approach the issue of deleted files by a mechanism of having the
1548 fd report to the dir, a list of all files on the client for every
1549 backup job. The dir could note in the database entry for each file
1550 the date that the file was seen. Then if a restore as of date X takes
1551 place, only files that exist from before X until after X would be
1552 restored. Probably the major cost here is the extra date container in
1553 each row of the files table.
1555 Thanks for "listening". I hope some of this helps. If you want to
1556 contact me, please send me an email - I read some but not all of the
1557 mailing list traffic and might miss a reply there.
1559 Please accept my compliments for bacula. It is doing a great job for
1560 me!! I sympathize with you in the need to wrestle with excelence in
1561 execution vs. excelence in feature inclusion.
1566 ==============================
1569 - Implement wait on multiple objects
1570 - Multiple max times
1572 - socket input ready
1573 - Design at hierarchial storage for Bacula. Migration and Clone.
1574 - Implement FSM (File System Modules).
1575 - Audit M_ error codes to ensure they are correct and consistent.
1576 - Add variable break characters to lex analyzer.
1577 Either a bit mask or a string of chars so that
1578 the caller can change the break characters.
1579 - Make a single T_BREAK to replace T_COMMA, etc.
1580 - Ensure that File daemon and Storage daemon can
1581 continue a save if the Director goes down (this
1582 is NOT currently the case). Must detect socket error,
1583 buffer messages for later.
1584 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1585 - Add ability to backup to two Storage devices (two SD sessions) at
1586 the same time -- e.g. onsite, offsite.
1587 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1588 someway to do so with every volume that has less than x% valid
1592 Migration: Move a backup from one Volume to another
1593 Clone: Copy a backup -- two Volumes
1596 ======================================================
1598 It is somewhat like a Full save becomes an incremental since
1599 the Base job (or jobs) plus other non-base files.
1601 - A Base backup is same as Full backup, just different type.
1602 - New BaseFiles table that contains:
1604 BaseJobId - Base JobId referenced for this FileId (needed ???)
1605 JobId - JobId currently running
1606 FileId - File not backed up, exists in Base Job
1607 FileIndex - FileIndex from Base Job.
1608 i.e. for each base file that exists but is not saved because
1609 it has not changed, the File daemon sends the JobId, BaseId,
1610 FileId, FileIndex back to the Director who creates the DB entry.
1611 - To initiate a Base save, the Director sends the FD
1612 the FileId, and full filename for each file in the Base.
1613 - When the FD finds a Base file, he requests the Director to
1614 send him the full File entry (stat packet plus MD5), or
1615 conversely, the FD sends it to the Director and the Director
1616 says yes or no. This can be quite rapid if the FileId is kept
1617 by the FD for each Base Filename.
1618 - It is probably better to have the comparison done by the FD
1619 despite the fact that the File entry must be sent across the
1621 - An alternative would be to send the FD the whole File entry
1622 from the start. The disadvantage is that it requires a lot of
1623 space. The advantage is that it requires less communications
1625 - The Job record must be updated to indicate that one or more
1627 - At end of Job, FD returns:
1628 1. Count of base files/bytes not written to tape (i.e. matches)
1629 2. Count of base file that were saved i.e. had changed.
1630 - No tape record would be written for a Base file that matches, in the
1631 same way that no tape record is written for Incremental jobs where
1632 the file is not saved because it is unchanged.
1633 - On a restore, all the Base file records must explicitly be
1634 found from the BaseFile tape. I.e. for each Full save that is marked
1635 to have one or more Base Jobs, search the BaseFile for all occurrences
1637 - An optimization might be to make the BaseFile have:
1643 This would avoid the need to explicitly fetch each File record for
1644 the Base job. The Base Job record will be fetched to get the
1645 VolSessionId and VolSessionTime.
1646 =========================================================
1649 ==========================================================
1651 For each Incremental job that is run, there may be files that
1652 were found but not saved because they were locked (this applies
1653 only to Windows). Such a system could send back to the Director
1654 a list of Unsaved files.
1656 - New UnSavedFiles table that contains:
1660 - Then in the next Incremental job, the list of Unsaved Files will be
1661 feed to the FD, who will ensure that they are explicitly chosen even
1662 if standard date/time check would not have selected them.
1663 =============================================================

1702 Unloading Data Transfer Element into Storage Element 15...done
1704 (just to verify it remembers where it came from, however it can be
1705 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1707 There needs to be a table of drive # to devices somewhere - If there are
1708 multiple changers or drives there may not be a 1:1 correspondance between
1709 changer drive number and system device name - and depending on the way the
1710 drives are hooked up to scsi busses, they may not be linearly numbered
1711 from an offset point either.something like
1713 Autochanger drives = 2
1714 Autochanger drive 0 = /dev/nst1
1715 Autochanger drive 1 = /dev/nst2
1716 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1717 times, not just for multidrive changers. For a 1 drive changer, that's
1723 MTX's manpage (1.2.15):
1724 unload [<slotnum>] [ <drivenum> ]
1725 Unloads media from drive <drivenum> into slot
1726 <slotnum>. If <drivenum> is omitted, defaults to
1727 drive 0 (as do all commands). If <slotnum> is
1728 omitted, defaults to the slot that the drive was
1729 loaded from. Note that there's currently no way
1730 to say 'unload drive 1's media to the slot it
1731 came from', other than to explicitly use that
1732 slot number as the destination.AB

1770 Handling removable disks
1772 From: Karl Cunningham <karlc@keckec.com>
1774 My backups are only to hard disk these days, in removable bays. This is my
1775 idea of how a backup to hard disk would work more smoothly. Some of these
1776 things Bacula does already, but I mention them for completeness. If others
1777 have better ways to do this, I'd like to hear about it.
1779 1. Accommodate several disks, rotated similar to how tapes are. Identified
1780 by partition volume ID or perhaps by the name of a subdirectory.
1781 2. Abort & notify the admin if the wrong disk is in the bay.
1782 3. Write backups to different subdirectories for each machine to be backed
1784 4. Volumes (files) get created as needed in the proper subdirectory, one
1786 5. When a disk is recycled, remove or zero all old backup files. This is
1787 important as the disk being recycled may be close to full. This may be
1788 better done manually since the backup files for many machines may be
1789 scattered in many subdirectories.
1794 - Why the heck doesn't bacula drop root priviledges before connecting to
1796 - Look at using posix_fadvise(2) for backups -- see bug #751.
1797 Possibly add the code at findlib/bfile.c:795
1798 /* TCP socket options */
1799 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1800 - Fix bnet_connect() code to set a timer and to use time to
1802 - Implement 4th argument to make_catalog_backup that passes hostname.
1803 - Test FIFO backup/restore -- make regression
1804 - Please mount volume "xxx" on Storage device ... should also list
1805 Pool and MediaType in case user needs to create a new volume.
1806 - On restore add Restore Client, Original Client.

1815 - Check if gnome-console works with TLS.
1816 - the director seg faulted when I omitted the pool directive from a
1817 job resource. I was experimenting and thought it redundant that I had
1818 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1819 apparently not. This happened when I removed the pool directive and
1820 started the director.
1821 - Add Where: client:/.... to restore job report.
1822 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1823 does the right thing.
1824 - FD-SD quick disconnect
1825 - Building the in memory restore tree is slow.
1826 - Erabt if min_block_size > max_block_size
1827 - Add the ability to consolidate old backup sets (basically do a restore
1828 to tape and appropriately update the catalog). Compress Volume sets.
1829 Might need to spool via file is only one drive is available.
