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

85 x = k[i] - (d[i] & 0xF))
87 x = k[i] - (d[i] & 0xF) + 16
90 - Eliminate: /var is a different filesystem. Will not descend from / into /var
91 - Separate Files and Directories in catalog
92 - Create FileVersions table
93 - Look at rsysnc for incremental updates and dedupping
94 - Add MD5 or SHA1 check in SD for data validation
95 - modify pruning to keep a fixed number of versions of a file,
97 - finish implementation of fdcalled -- see ua_run.c:105
98 - Fix problem in postgresql.c in my_postgresql_query, where the
99 generation of the error message doesn't differentiate result==NULL
100 and a bad status from that result. Not only that, the result is
101 cleared on a bail_out without having generated the error message.
102 - Erabt if min_block_size > max_block_size

121 - Add TLS to bat (should be done).
122 - When Pool specifies Storage command override does not work.
123 - Implement wait_for_sysop() message display in wait_for_device(), which
124 now prints warnings too often.
125 - Ensure that each device in an Autochanger has a different
127 - Add Catalog = to Pool resource so that pools will exist
128 in only one catalog -- currently Pools are "global".
129 - Look at sg_logs -a /dev/sg0 for getting soft errors.
130 - btape "test" command with Offline on Unmount = yes
132 This test is essential to Bacula.

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

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

196 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
197 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
201 - Add doc for bweb -- especially Installation
203 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
205 - Despool attributes in separate thread
208 - Check why restore repeatedly sends Rechdrs between
209 each data chunk -- according to James Harper 9Jan07.

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

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

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

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

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

563 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
564 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
565 - Implement a mode that says when a hard read error is
566 encountered, read many times (as it currently does), and if the
567 block cannot be read, skip to the next block, and try again. If
568 that fails, skip to the next file and try again, ...
570 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
571 insert into LevelType (LevelType,LevelTypeLong) values
575 - Show files/second in client status output.
576 - Add a recursive mark command (rmark) to restore.
577 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
578 of the same level and does not permit multiple simultaneous
579 running of that Job (i.e. lets any previous invocation finish
580 before doing Interval testing).
581 - Look at simplifying File exclusions.
582 - New directive "Delete purged Volumes"
583 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
584 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
585 see if it become stable and I just have to supervise
587 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
588 PoolId, and when it is empty remove it.
589 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
591 - Allow Check Labels to be used with Bacula labels.
592 - "Resuming" a failed backup (lost line for example) by using the
593 failed backup as a sort of "base" job.
595 - Email to the user when the tape is about to need changing x
596 days before it needs changing.
597 - Command to show next tape that will be used for a job even
598 if the job is not scheduled.
599 - From: Arunav Mandal <amandal@trolltech.com>
600 1. When jobs are running and bacula for some reason crashes or if I do a
601 restart it remembers and jobs it was running before it crashed or restarted
602 as of now I loose all jobs if I restart it.
604 2. When spooling and in the midway if client is disconnected for instance a
605 laptop bacula completely discard the spool. It will be nice if it can write
606 that spool to tape so there will be some backups for that client if not all.
608 3. We have around 150 clients machines it will be nice to have a option to
609 upgrade all the client machines bacula version automatically.
611 4. Atleast one connection should be reserved for the bconsole so at heavy load
612 I should connect to the director via bconsole which at sometimes I can't
614 5. Another most important feature that is missing, say at 10am I manually
615 started backup of client abc and it was a full backup since client abc has
616 no backup history and at 10.30am bacula again automatically started backup of
617 client abc as that was in the schedule. So now we have 2 multiple Full
618 backups of the same client and if we again try to start a full backup of
619 client backup abc bacula won't complain. That should be fixed.
621 - Fix bpipe.c so that it does not modify results pointer.
622 ***FIXME*** calling sequence should be changed.
623 - For Windows disaster recovery see http://unattended.sf.net/
624 - regardless of the retention period, Bacula will not prune the
625 last Full, Diff, or Inc File data until a month after the
626 retention period for the last Full backup that was done.
627 - update volume=xxx --- add status=Full
628 - Remove old spool files on startup.
629 - Exclude SD spool/working directory.
630 - Refuse to prune last valid Full backup. Same goes for Catalog.
632 - Make a callback when Rerun failed levels is called.
633 - Give Python program access to Scheduled jobs.
634 - Add setting Volume State via Python.
635 - Python script to save with Python, not save, save with Bacula.
636 - Python script to do backup.
638 - Change the Priority, Client, Storage, JobStatus (error)
639 at the start of a job.
640 - Why is SpoolDirectory = /home/bacula/spool; not reported
641 as an error when writing a DVD?
642 - Make bootstrap file handle multiple MediaTypes (SD)
643 - Remove all old Device resource code in Dir and code to pass it
644 back in SD -- better, rework it to pass back device statistics.
645 - Check locking of resources -- be sure to lock devices where previously
646 resources were locked.
647 - The last part is left in the spool dir.
650 - In restore don't compare byte count on a raw device -- directory
651 entry does not contain bytes.
655 MA = (last_MA * 3 + rate) / 4
656 rate = (bytes - last_bytes) / (runtime - last_runtime)
657 - Max Vols limit in Pool off by one?
658 - Implement Files/Bytes,... stats for restore job.
659 - Implement Total Bytes Written, ... for restore job.
660 - Despool attributes simultaneously with data in a separate
661 thread, rejoined at end of data spooling.
662 - 7. Implement new Console commands to allow offlining/reserving drives,
663 and possibly manipulating the autochanger (much asked for).
664 - Add start/end date editing in messages (%t %T, %e?) ...
665 - Add ClientDefs similar to JobDefs.
666 - Print more info when bextract -p accepts a bad block.
667 - Fix FD JobType to be set before RunBeforeJob in FD.
668 - Look at adding full Volume and Pool information to a Volume
669 label so that bscan can get *all* the info.
670 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
671 and there is only one volume in the pool, refuse to do it -- otherwise
672 he fills the Volume, then immediately starts reusing it.
673 - Implement copies and stripes.
674 - Add history file to console.
675 - Each file on tape creates a JobMedia record. Peter has 4 million
676 files spread over 10000 tape files and four tapes. A restore takes
677 16 hours to build the restore list.
678 - Add and option to check if the file size changed during backup.
679 - Make sure SD deletes spool files on error exit.
680 - Delete old spool files when SD starts.
681 - When labeling tapes, if you enter 000026, Bacula uses
682 the tape index rather than the Volume name 000026.
683 - Add offline tape command to Bacula console.
685 Enter MediaId or Volume name: 32
686 Enter new Volume name: DLT-20Dec04
687 Automatically selected Pool: Default
688 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

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

845 === From Carsten Menke <bootsy52@gmx.net>
847 Following is a list of what I think in the situations where I'm faced with,
848 could be a usefull enhancement to bacula, which I'm certain other users will
849 benefit from as well.
851 1. NextJob/NextJobs Directive within a Job Resource in the form of
852 NextJobs = job1,job2.
855 I currently solved the problem with running multiple jobs each after each
856 by setting the Max Wait Time for a job to 8 hours, and give
857 the jobs different Priorities. However, there scenarios where
858 1 Job is directly depending on another job, so if the former job fails,
859 the job after it needn't to be run
860 while maybe other jobs should run despite of that
863 A Backup Job and a Verify job, if the backup job fails there is no need to run
864 the verify job, as the backup job already failed. However, one may like
865 to backup the Catalog to disk despite of that the main backup job failed.
868 I see that this is related to the Event Handlers which are on the ToDo
869 list, also it is maybe a good idea to check for the return value and
870 execute different actions based on the return value
873 3. offline capability to bconsole
876 Currently I use a script which I execute within the last Job via the
877 RunAfterJob Directive, to release and eject the tape.
878 So I have to call bconsole "release=Storage-Name" and afterwards
879 mt -f /dev/nst0 eject to get the tape out.
881 If I have multiple Storage Devices, than these may not be /dev/nst0 and
882 I have to modify the script or call it with parameters etc.
883 This would actually not be needed, as everything is already defined
884 in bacula-sd.conf and if I can invoke bconsole with the
885 storage name via $1 in the script than I'm done and information is
888 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
892 For the reason mentioned in 3. to have the ability to call a
893 script with /scripts/foobar %s and in the script use $1
894 to pass the Storage Name to bconsole
896 5. Setting Volume State within a Job Resource
899 Instead of using "Maximum Volume Jobs" in the Pool Resource,
900 I would have the possibilty to define
901 in a Job Resource that after this certain job is run, the Volume State
902 should be set to "Volume State = Used", this give more flexibility (IMHO).
904 6. Localization of Bacula Messages
907 Unfortunatley many,many people I work with don't speak english very well.
908 So if at least the Reporting messages would be localized then they
909 would understand that they have to change the tape,etc. etc.
911 I volunteer to do the german translations, and if I can convince my wife also
912 french and Morre (western african language).
914 7. OK, this is evil, probably bound to security risks and maybe not possible
915 due to the design of bacula.
917 Implementation of Backtics ( `command` ) for shell comand execution to
918 the "Label Format" Directive.
922 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
923 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
924 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
925 the localized name for the day of the week appended to the
926 format string. Then I have the tape labeled automatically with weekday
927 name in the correct language.
929 - Yes, that is surely the case. I probably should turn those into Warning
930 errors. In addition, you just made me think that it might not be bad to
931 add an option to check the file size after backing up the file and
932 report if it changes. This would be done as an option because it would
935 Kern, good idea. If you do do that, mention in the output: file
936 shrunk, or file expanded, just to make it obvious to the user
937 (without having to the refer to file size), just how the file size
940 Would this option be for all file, or just one file? Or a fileset?
941 - Make output from status use html table tags for nicely
942 presenting in a browser.
943 - Can one write tapes faster with 8192 byte block sizes?
944 - Document security problems with the same password for everyone in
945 rpm and Win32 releases.
946 - Browse generations of files.
947 - I've seen an error when my catalog's File table fills up. I
948 then have to recreate the File table with a larger maximum row
949 size. Relevant information is at
950 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
951 "Installing and Configuring MySQL" chapter should talk a bit
952 about this potential problem, and recommend a solution.
953 - For Solaris must use POSIX awk.
954 - Want speed of writing to tape while despooling.
955 - Supported autochanger:
963 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
964 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
965 - Add regex from http://www.pcre.org to Bacula for Win32.
966 - Use only shell tools no make in CDROM package.
967 - Include within include does it work?
968 - Implement a Pool of type Cleaning?
969 - Implement VolReadTime and VolWriteTime in SD
970 - Modify Backing up Your Database to include a bootstrap file.
971 - Think about making certain database errors fatal.
972 - Look at correcting the time jump in the scheduler for daylight
973 savings time changes.
974 - Add a "real" timer to network connections.
975 - Promote to Full = Time period
976 - Check dates entered by user for correctness (month/day/... ranges)
977 - Compress restore Volume listing by date and first file.
978 - Look at patches/bacula_db.b2z postgresql that loops during restore.
980 - Perhaps add read/write programs and/or plugins to FileSets.
981 - How to handle backing up portables ...
982 - Add some sort of guaranteed Interval for upgrading jobs.
983 - Can we write the state file after every job terminates? On Win32
984 the system crashes and the state file is not updated.
987 Documentation to do: (any release a little bit at a time)
988 - Doc to do unmount before removing magazine.
989 - Alternative to static linking "ldd prog" save all binaries listed,
990 restore them and point LD_LIBRARY_PATH to them.
991 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
992 - Document query file format.
993 - Add more documentation for bsr files.
994 - Document problems with Verify and pruning.
995 - Document how to use multiple databases.
996 - VXA drives have a "cleaning required"
997 indicator, but Exabyte recommends preventive cleaning after every 75
1000 In this context, it should be noted that Exabyte has a command-line
1001 vxatool utility available for free download. (The current version is
1002 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
1003 test the drive, unload tapes, change drive settings, flash new firmware,
1005 Of particular interest in this context is that vxatool <device> -i will
1006 report, among other details, the time since last cleaning in tape motion
1007 minutes. This information can be retrieved (and settings changed, for
1008 that matter) through the generic-SCSI device even when Bacula has the
1009 regular tape device locked. (Needless to say, I don't recommend
1010 changing tape settings while a job is running.)
1011 - Lookup HP cleaning recommendations.
1012 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
1013 - Document doing table repair
1016 ===================================
1017 - Add macro expansions in JobDefs.
1018 Run Before Job = "SomeFile %{Level} %{Client}"
1019 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
1020 - Use non-blocking network I/O but if no data is available, use
1022 - Use gather write() for network I/O.
1023 - Autorestart on crash.
1024 - Add bandwidth limiting.
1025 - Add acks every once and a while from the SD to keep
1026 the line from timing out.
1027 - When an error in input occurs and conio beeps, you can back
1028 up through the prompt.
1029 - Detect fixed tape block mode during positioning by looking at
1030 block numbers in btape "test". Possibly adjust in Bacula.
1031 - Fix list volumes to output volume retention in some other
1032 units, perhaps via a directive.
1033 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
1034 with multiple priorities.
1035 - If you use restore replace=never, the directory attributes for
1036 non-existent directories will not be restored properly.
1038 - see lzma401.zip in others directory for new compression
1040 - Allow the user to select JobType for manual pruning/purging.
1041 - bscan does not put first of two volumes back with all info in
1043 - Implement the FreeBSD nodump flag in chflags.
1044 - Figure out how to make named console messages go only to that
1045 console and to the non-restricted console (new console class?).
1046 - Make restricted console prompt for password if *ask* is set or
1047 perhaps if password is undefined.
1048 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1051 ==== from Marc Schoechlin
1052 - the help-command should be more verbose
1053 (it should explain the paramters of the different
1055 -> its time-comsuming to consult the manual anytime
1056 you need a special parameter
1057 -> maybe its more easy to maintain this, if the
1058 descriptions of that commands are outsourced to
1060 - the cd-command should allow complete paths
1061 i.e. cd /foo/bar/foo/bar
1062 -> if a customer mails me the path to a certain file,
1063 its faster to enter the specified directory
1064 - if the password is not configured in bconsole.conf
1065 you should be asked for it.
1066 -> sometimes you like to do restore on a customer-machine
1067 which shouldnt know the password for bacula.
1068 -> adding the password to the file favours admins
1069 to forget to remove the password after usage
1071 the protection of that file is less important
1072 - long-listed-output of commands should be scrollable
1073 like the unix more/less-command does
1074 -> if someone runs 200 and more machines, the lists could
1075 be a little long and complex
1076 - command-output should be shown column by column
1077 to reduce scrolling and to increase clarity
1079 - lsmark should list the selected files with full
1081 - wildcards for selecting and file and directories would be nice
1082 - any actions should be interuptable with STRG+C
1083 - command-expansion would be pretty cool
1085 - When the replace Never option is set, new directory permissions
1086 are not restored. See bug 213. To fix this requires creating a
1087 list of newly restored directories so that those directory
1088 permissions *can* be restored.
1089 - Add prune all command
1090 - Document fact that purge can destroy a part of a restore by purging
1091 one volume while others remain valid -- perhaps mark Jobs.
1092 - Add multiple-media-types.txt
1093 - look at mxt-changer.html
1094 - Make ? do a help command (no return needed).
1095 - Implement restore directory.
1096 - Document streams and how to implement them.
1097 - Try not to re-backup a file if a new hard link is added.
1098 - Add feature to backup hard links only, but not the data.
1099 - Fix stream handling to be simpler.
1100 - Add Priority and Bootstrap to Run a Job.
1101 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1103 - Remove View FileSet button from Run a Job dialog.
1104 - Handle prompt for restore job at end of Restore command.
1105 - Add display of total selected files to Restore window.
1106 - Add tree pane to left of window.
1107 - Add progress meter.
1108 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1109 - Add message to user to check for fixed block size when the forward
1110 space test fails in btape.
1111 - When unmarking a directory check if all files below are unmarked and
1112 then remove the + flag -- in the restore tree.
1113 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1114 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1115 - Revisit the question of multiple Volumes (disk) on a single device.
1116 - Add a block copy option to bcopy.
1117 - Finish work on Gnome restore GUI.
1118 - Fix "llist jobid=xx" where no fileset or client exists.
1119 - For each job type (Admin, Restore, ...) require only the really necessary
1120 fields.- Pass Director resource name as an option to the Console.
1121 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1122 - Add a .list all files in the restore tree (probably also a list all files)
1123 Do both a long and short form.
1124 - Allow browsing the catalog to see all versions of a file (with
1125 stat data on each file).
1126 - Restore attributes of directory if replace=never set but directory
1128 - Use SHA1 on authentication if possible.
1129 - See comtest-xxx.zip for Windows code to talk to USB.
1130 - Add John's appended files:
1131 Appended = { /files/server/logs/http/*log }
1132 and such files would be treated as follows.On a FULL backup, they would
1133 be backed up like any other file.On an INCREMENTAL backup, where a
1134 previous INCREMENTAL or FULL was already in thecatalogue and the length
1135 of the file wasgreater than the length of the last backup, only thedata
1136 added since the last backup will be dumped.On an INCREMENTAL backup, if
1137 the length of the file is less than thelength of the file with the same
1138 name last backed up, the completefile is dumped.On Windows systems, with
1139 creation date of files, we can be evensmarter about this and not count
1140 entirely upon the length.On a restore, the full and all incrementals
1141 since it will beapplied in sequence to restore the file.
1142 - Check new HAVE_WIN32 open bits.
1143 - Check if the tape has moved before writing.
1144 - Handling removable disks -- see below:
1145 - Keep track of tape use time, and report when cleaning is necessary.
1146 - Add FromClient and ToClient keywords on restore command (or
1147 BackupClient RestoreClient).
1148 - Implement a JobSet, which groups any number of jobs. If the
1149 JobSet is started, all the jobs are started together.
1150 Allow Pool, Level, and Schedule overrides.
1151 - Enhance cancel to timeout BSOCK packets after a specific delay.
1152 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1153 ua_status.!!! Thanks to Alan Brown for this tip.
1154 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1155 correctly for multiple simultaneous jobs.
1156 - Correct code so that FileSet MD5 is calculated for < and | filename
1158 - Implement the Media record flag that indicates that the Volume does disk
1160 - Implement VolAddr, which is used when Volume is addressed like a disk,
1161 and form it from VolFile and VolBlock.
1162 - Make multiple restore jobs for multiple media types specifying
1163 the proper storage type.
1164 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1165 pointer (rec) to try_repositioning().
1166 - Look at extracting Win data from BackupRead.
1167 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1168 which would take precidence over the Catalog "JobRetention".
1169 - Implement Label Format in Add and Label console commands.
1170 - Possibly up network buffers to 65K. Put on variable.
1171 - Put email tape request delays on one or more variables. User wants
1172 to cancel the job after a certain time interval. Maximum Mount Wait?
1173 - Job, Client, Device, Pool, or Volume?
1174 Is it possible to make this a directive which is *optional* in multiple
1175 resources, like Level? If so, I think I'd make it an optional directive
1176 in Job, Client, and Pool, with precedence such that Job overrides Client
1177 which in turn overrides Pool.
1179 - New Storage specifications:
1180 - Want to write to multiple storage devices simultaneously
1181 - Want to write to multiple storage devices sequentially (in one job)
1182 - Want to read/write simultaneously
1183 - Key is MediaType -- it must match
1185 Passed to SD as a sort of BSR record called Storage Specification
1189 MediaType -> Next MediaType
1191 Device -> Next Device
1193 Allow multiple Storage specifications
1201 Allow Multiple Pool specifications (note, Pool currently
1203 Allow Multiple MediaType specifications in Dir conf
1204 Allow Multiple Device specifications in Dir conf
1205 Perhaps keep this in a single SSR
1206 Tie a Volume to a specific device by using a MediaType that
1207 is contained in only one device.
1208 In SD allow Device to have Multiple MediaTypes
1210 - Ideas from Jerry Scharf:
1211 First let's point out some big pluses that bacula has for this
1213 more importantly it's active. Thank you so much for that
1214 even more important, it's not flaky
1215 it has an open access catalog, opening many possibilities
1216 it's pushing toward heterogeneous systems capability
1218 Macintosh file client
1219 macs are an interesting niche, but I fear a server is a rathole
1220 working bare iron recovery for windows
1221 the option for inc/diff backups not reset on fileset revision
1222 a) use both change and inode update time against base time
1223 b) do the full catalog check (expensive but accurate)
1224 sizing guide (how much system is needed to back up N systems/files)
1225 consultants on using bacula in building a disaster recovery system
1226 an integration guide
1227 or how to get at fancy things that one could do with bacula
1228 logwatch code for bacula logs (or similar)
1229 linux distro inclusion of bacula (brings good and bad, but necessary)
1230 win2k/XP server capability (icky but you asked)
1231 support for Oracle database ??
1233 - Look at adding SQL server and Exchange support for Windows.
1234 - Make dev->file and dev->block_num signed integers so that -1 can
1235 be an invalid value which happens with BSR.
1236 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1237 is needed to properly specify ranges.
1238 - Add progress of files/bytes to SD and FD.
1239 - Print warning message if FileId > 4 billion
1240 - do a "messages" before the first prompt in Console
1241 - Client does not show busy during Estimate command.
1242 - Implement Console mtx commands.
1243 - Implement a Mount Command and an Unmount Command where
1244 the users could specify a system command to be performed
1245 to do the mount, after which Bacula could attempt to
1246 read the device. This is for Removeable media such as a CDROM.
1247 - Most likely, this mount command would be invoked explicitly
1248 by the user using the current Console "mount" and "unmount"
1249 commands -- the Storage Daemon would do the right thing
1250 depending on the exact nature of the device.
1251 - As with tape drives, when Bacula wanted a new removable
1252 disk mounted, it would unmount the old one, and send a message
1253 to the user, who would then use "mount" as described above
1254 once he had actually inserted the disk.
1255 - Implement dump/print label to UA
1256 - Spool to disk only when the tape is full, then when a tape is hung move
1258 - bextract is sending everything to the log file ****FIXME****
1259 - Allow multiple Storage specifications (or multiple names on
1260 a single Storage specification) in the Job record. Thus a job
1261 can be backed up to a number of storage devices.
1262 - Implement some way for the File daemon to contact the Director
1263 to start a job or pass its DHCP obtained IP number.
1264 - Implement a query tape prompt/replace feature for a console
1265 - Copy console @ code to gnome2-console
1266 - Make tree walk routines like cd, ls, ... more user friendly
1267 by handling spaces better.
1268 - Make sure that Bacula rechecks the tape after the 20 min wait.
1269 - Set IO_NOWAIT on Bacula TCP/IP packets.
1270 - Try doing a raw partition backup and restore by mounting a
1272 - From Lars Kellers:
1273 Yes, it would allow to highly automatic the request for new tapes. If a
1274 tape is empty, bacula reads the barcodes (native or simulated), and if
1275 an unused tape is found, it runs the label command with all the
1276 necessary parameters.
1278 By the way can bacula automatically "move" an empty/purged volume say
1279 in the "short" pool to the "long" pool if this pool runs out of volume
1281 - What to do about "list files job=xxx".
1282 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1283 file descriptor leak in Bacula.
1284 - Implement WrapCounters in Counters.
1285 - Add heartbeat from FD to SD if hb interval expires.
1286 - Can we dynamically change FileSets?
1287 - If pool specified to label command and Label Format is specified,
1288 automatically generate the Volume name.
1289 - Why can't SQL do the filename sort for restore?
1290 - Add ExhautiveRestoreSearch
1291 - Look at the possibility of loading only the necessary
1292 data into the restore tree (i.e. do it one directory at a
1293 time as the user walks through the tree).
1294 - Possibly use the hash code if the user selects all for a restore command.
1295 - Fix "restore all" to bypass building the tree.
1296 - Prohibit backing up archive device (findlib/find_one.c:128)
1297 - Implement Release Device in the Job resource to unmount a drive.
1298 - Implement Acquire Device in the Job resource to mount a drive,
1299 be sure this works with admin jobs so that the user can get
1300 prompted to insert the correct tape. Possibly some way to say to
1301 run the job but don't save the files.
1302 - Make things like list where a file is saved case independent for
1304 - Use autochanger to handle multiple devices.
1305 - Implement a Recycle command
1306 - Start working on Base jobs.
1307 - Implement UnsavedFiles DB record.
1308 - From Phil Stracchino:
1309 It would probably be a per-client option, and would be called
1310 something like, say, "Automatically purge obsoleted jobs". What it
1311 would do is, when you successfully complete a Differential backup of a
1312 client, it would automatically purge all Incremental backups for that
1313 client that are rendered redundant by that Differential. Likewise,
1314 when a Full backup on a client completed, it would automatically purge
1315 all Differential and Incremental jobs obsoleted by that Full backup.
1316 This would let people minimize the number of tapes they're keeping on
1317 hand without having to master the art of retention times.
1318 - When doing a Backup send all attributes back to the Director, who
1319 would then figure out what files have been deleted.
1320 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1321 explicit permission to do so. It should also mark the tape in error
1322 if there is an error.
1323 - Cancel waiting for Client connect in SD if FD goes away.
1325 - Implement timeout in response() when it should come quickly.
1326 - Implement a Slot priority (loaded/not loaded).
1327 - Implement "vacation" Incremental only saves.
1328 - Implement create "FileSet"?
1329 - Add prefixlinks to where or not where absolute links to FD.
1330 - Issue message to mount a new tape before the rewind.
1331 - Simplified client job initiation for portables.
1332 - If SD cannot open a drive, make it periodically retry.
1333 - Add more of the config info to the tape label.
1335 - Refine SD waiting output:
1336 Device is being positioned
1337 > Device is being positioned for append
1338 > Device is being positioned to file x
1340 - Figure out some way to estimate output size and to avoid splitting
1341 a backup across two Volumes -- this could be useful for writing CDROMs
1342 where you really prefer not to have it split -- not serious.
1343 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1344 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1345 actual data on the Volume and compare it.
1346 - Implement Bacula plugins -- design API
1347 - Make bcopy read through bad tape records.
1348 - Program files (i.e. execute a program to read/write files).
1349 Pass read date of last backup, size of file last time.
1350 - Add Signature type to File DB record.
1351 - CD into subdirectory when open()ing files for backup to
1352 speed up things. Test with testfind().
1353 - Priority job to go to top of list.
1354 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1355 - Implement some way for the Console to dynamically create a job.
1356 - Solaris -I on tar for include list
1357 - Need a verbose mode in restore, perhaps to bsr.
1358 - bscan without -v is too quiet -- perhaps show jobs.
1359 - Add code to reject whole blocks if not wanted on restore.
1360 - Check if we can increase Bacula FD priorty in Win2000
1361 - Make sure the MaxVolFiles is fully implemented in SD
1362 - Check if both CatalogFiles and UseCatalog are set to SD.
1363 - Possibly add email to Watchdog if drive is unmounted too
1364 long and a job is waiting on the drive.
1365 - After unmount, if restore job started, ask to mount.
1366 - Add UA rc and history files.
1367 - put termcap (used by console) in ./configure and
1368 allow -with-termcap-dir.
1369 - Fix Autoprune for Volumes to respect need for full save.
1370 - Compare tape to Client files (attributes, or attributes and data)
1371 - Make all database Ids 64 bit.
1372 - Allow console commands to detach or run in background.
1373 - Add SD message variables to control operator wait time
1374 - Maximum Operator Wait
1375 - Minimum Message Interval
1376 - Maximum Message Interval
1377 - Send Operator message when cannot read tape label.
1378 - Verify level=Volume (scan only), level=Data (compare of data to file).
1379 Verify level=Catalog, level=InitCatalog
1381 - Add keyword search to show command in Console.
1382 - Events : tape has more than xxx bytes.
1383 - Complete code in Bacula Resources -- this will permit
1384 reading a new config file at any time.
1385 - Handle ctl-c in Console
1386 - Implement script driven addition of File daemon to config files.
1387 - Think about how to make Bacula work better with File (non-tape) archives.
1388 - Write Unix emulator for Windows.
1389 - Put memory utilization in Status output of each daemon
1390 if full status requested or if some level of debug on.
1391 - Make database type selectable by .conf files i.e. at runtime
1392 - Set flag for uname -a. Add to Volume label.
1393 - Restore files modified after date
1394 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1395 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1396 - Timout a job or terminate if link goes down, or reopen link and query.
1397 - Concept of precious tapes (cannot be reused).
1398 - Make bcopy copy with a single tape drive.
1399 - Permit changing ownership during restore.

1413 - Autolabel should be specified by DIR instead of SD.
1415 - Add media capacity
1416 - AutoScan (check checksum of tape)
1417 - Format command = "format /dev/nst0"
1421 - Seek resolution (usually corresponds to buffer size)
1422 - EODErrorCode=ENOSPC or code
1423 - Partial Read error code
1424 - Partial write error code
1425 - Nonformatted read error
1426 - Nonformatted write error
1427 - WriteProtected error
1431 - IgnoreCloseErrors=yes
1441 - FD sends unsaved file list to Director at end of job (see
1443 - File daemon should build list of files skipped, and then
1444 at end of save retry and report any errors.
1445 - Write a Storage daemon that uses pipes and
1446 standard Unix programs to write to the tape.
1448 - Need something that monitors the JCR queue and
1449 times out jobs by asking the deamons where they are.
1450 - Enhance Jmsg code to permit buffering and saving to disk.
1451 - device driver = "xxxx" for drives.
1452 - Verify from Volume
1453 - Ensure that /dev/null works
1454 - Need report class for messages. Perhaps
1455 report resource where report=group of messages
1456 - enhance scan_attrib and rename scan_jobtype, and
1457 fill in code for "since" option
1458 - Director needs a time after which the report status is sent
1459 anyway -- or better yet, a retry time for the job.
1460 - Don't reschedule a job if previous incarnation is still running.
1461 - Some way to automatically backup everything is needed????
1462 - Need a structure for pending actions:
1464 - termination status (part of buffered msgs?)
1466 Read, Write, Clean, Delete
1467 - Login to Bacula; Bacula users with different permissions:
1468 owner, group, user, quotas
1469 - Store info on each file system type (probably in the job header on tape.
1470 This could be the output of df; or perhaps some sort of /etc/mtab record.
1472 ========= ideas ===============
1473 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1474 To: <kern@sibbald.com>
1475 Subject: RE: [Bacula-users] future large programming jobs
1476 Date: Thu, 26 Feb 2004 11:34:54 -0600
1478 I noticed the subject thread and thought I would offer the following
1479 merely as sources of ideas, i.e. something to think about, not even as
1480 strong as a request. In my former life (before retiring) I often
1481 dealt with backups and storage management issues/products as a
1482 developer and as a consultant. I am currently migrating my personal
1483 network from amanda to bacula specifically because of the ability to
1484 cross media boundaries during storing backups.
1485 Are you familiar with the commercial product called ADSM (I think IBM
1486 now sells it under the Tivoli label)? It has a couple of interesting
1487 ideas that may apply to the following topics.
1489 1. Migration: Consider that when you need to restore a system, there
1490 may be pressure to hurry. If all the information for a single client
1491 can eventually end up on the same media (and in chronological order),
1492 the restore is facillitated by not having to search past information
1493 from other clients. ADSM has the concept of "client affinity" that
1494 may be associated with it's storage pools. It seems to me that this
1495 concept (as an optional feature) might fit in your architecture for
1498 ADSM also has the concept of defining one or more storage pools as
1499 "copy pools" (almost mirrors, but only in the sense of contents).
1500 These pools provide the ability to have duplicte data stored both
1501 onsite and offsite. The copy process can be scheduled to be handled
1502 by their storage manager during periods when there is no backup
1503 activity. Again, the migration process might be a place to consider
1504 implementing something like this.
1507 > It strikes me that it would be very nice to be able to do things
1509 > have the Job(s) backing up the machines run, and once they have all

1515 > mechanism described below would probably make it very easy.
1517 This is the goal. In the first step (before events), you simply
1519 the Migration to tape later.
1521 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1522 the database. Once a file (unique by path and metadata such as dates,
1523 size, ownership, etc.) is in a copy pool, no more copies are made. In
1524 other words, when you start ADSM, it begins like your concept of a
1525 base job. After that it is in the "incremental" mode. You can
1526 configure the number of "generations" of files to be retained, plus a
1527 retention date after which even old generations are purged. The
1528 database tracks the contents of media and projects the percentage of
1529 each volume that is valid. When the valid content of a volume drops
1530 below a configured percentage, the valid data are migrated to another
1531 volume and the old volume is marked as empty. Note, this requires
1532 ADSM to have an idea of the contents of a client, i.e. marking the
1533 database when an existing file was deleted, but this would solve your
1534 issue of restoring a client without restoring deleted files.
1536 This is pretty far from what bacula now does, but if you are going to
1537 rip things up for Base jobs,.....
1538 Also, the benefits of this are huge for very large shops, especially
1539 with media robots, but are a pain for shops with manual media
1543 > Base jobs sound pretty useful, but I'm not dying for them.
1545 Nobody is dying for them, but when you see what it does, you will die
1548 3. Restoring deleted files: Since I think my comments in (2) above
1549 have low probability of implementation, I'll also suggest that you
1550 could approach the issue of deleted files by a mechanism of having the
1551 fd report to the dir, a list of all files on the client for every
1552 backup job. The dir could note in the database entry for each file
1553 the date that the file was seen. Then if a restore as of date X takes
1554 place, only files that exist from before X until after X would be
1555 restored. Probably the major cost here is the extra date container in
1556 each row of the files table.
1558 Thanks for "listening". I hope some of this helps. If you want to
1559 contact me, please send me an email - I read some but not all of the
1560 mailing list traffic and might miss a reply there.
1562 Please accept my compliments for bacula. It is doing a great job for
1563 me!! I sympathize with you in the need to wrestle with excelence in
1564 execution vs. excelence in feature inclusion.
1569 ==============================
1572 - Design at hierarchial storage for Bacula. Migration and Clone.
1573 - Implement FSM (File System Modules).
1574 - Audit M_ error codes to ensure they are correct and consistent.
1575 - Add variable break characters to lex analyzer.
1576 Either a bit mask or a string of chars so that
1577 the caller can change the break characters.
1578 - Make a single T_BREAK to replace T_COMMA, etc.
1579 - Ensure that File daemon and Storage daemon can
1580 continue a save if the Director goes down (this
1581 is NOT currently the case). Must detect socket error,
1582 buffer messages for later.
1583 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1584 - Add ability to backup to two Storage devices (two SD sessions) at
1585 the same time -- e.g. onsite, offsite.
1586 - Add the ability to consolidate old backup sets (basically do a restore
1587 to tape and appropriately update the catalog). Compress Volume sets.
1588 Might need to spool via file is only one drive is available.
1589 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1590 someway to do so with every volume that has less than x% valid
1594 Migration: Move a backup from one Volume to another
1595 Clone: Copy a backup -- two Volumes
1598 ======================================================
1600 It is somewhat like a Full save becomes an incremental since
1601 the Base job (or jobs) plus other non-base files.
1603 - A Base backup is same as Full backup, just different type.
1604 - New BaseFiles table that contains:
1606 BaseJobId - Base JobId referenced for this FileId (needed ???)
1607 JobId - JobId currently running
1608 FileId - File not backed up, exists in Base Job
1609 FileIndex - FileIndex from Base Job.
1610 i.e. for each base file that exists but is not saved because
1611 it has not changed, the File daemon sends the JobId, BaseId,
1612 FileId, FileIndex back to the Director who creates the DB entry.
1613 - To initiate a Base save, the Director sends the FD
1614 the FileId, and full filename for each file in the Base.
1615 - When the FD finds a Base file, he requests the Director to
1616 send him the full File entry (stat packet plus MD5), or
1617 conversely, the FD sends it to the Director and the Director
1618 says yes or no. This can be quite rapid if the FileId is kept
1619 by the FD for each Base Filename.
1620 - It is probably better to have the comparison done by the FD
1621 despite the fact that the File entry must be sent across the
1623 - An alternative would be to send the FD the whole File entry
1624 from the start. The disadvantage is that it requires a lot of
1625 space. The advantage is that it requires less communications
1627 - The Job record must be updated to indicate that one or more
1629 - At end of Job, FD returns:
1630 1. Count of base files/bytes not written to tape (i.e. matches)
1631 2. Count of base file that were saved i.e. had changed.
1632 - No tape record would be written for a Base file that matches, in the
1633 same way that no tape record is written for Incremental jobs where
1634 the file is not saved because it is unchanged.
1635 - On a restore, all the Base file records must explicitly be
1636 found from the BaseFile tape. I.e. for each Full save that is marked
1637 to have one or more Base Jobs, search the BaseFile for all occurrences
1639 - An optimization might be to make the BaseFile have:
1645 This would avoid the need to explicitly fetch each File record for
1646 the Base job. The Base Job record will be fetched to get the
1647 VolSessionId and VolSessionTime.
1648 =========================================================
1651 ==========================================================
1653 For each Incremental job that is run, there may be files that
1654 were found but not saved because they were locked (this applies
1655 only to Windows). Such a system could send back to the Director
1656 a list of Unsaved files.
1658 - New UnSavedFiles table that contains:
1662 - Then in the next Incremental job, the list of Unsaved Files will be
1663 feed to the FD, who will ensure that they are explicitly chosen even
1664 if standard date/time check would not have selected them.
1665 =============================================================

1704 Unloading Data Transfer Element into Storage Element 15...done
1706 (just to verify it remembers where it came from, however it can be
1707 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1709 There needs to be a table of drive # to devices somewhere - If there are
1710 multiple changers or drives there may not be a 1:1 correspondance between
1711 changer drive number and system device name - and depending on the way the
1712 drives are hooked up to scsi busses, they may not be linearly numbered
1713 from an offset point either.something like
1715 Autochanger drives = 2
1716 Autochanger drive 0 = /dev/nst1
1717 Autochanger drive 1 = /dev/nst2
1718 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1719 times, not just for multidrive changers. For a 1 drive changer, that's
1725 MTX's manpage (1.2.15):
1726 unload [<slotnum>] [ <drivenum> ]
1727 Unloads media from drive <drivenum> into slot
1728 <slotnum>. If <drivenum> is omitted, defaults to
1729 drive 0 (as do all commands). If <slotnum> is
1730 omitted, defaults to the slot that the drive was
1731 loaded from. Note that there's currently no way
1732 to say 'unload drive 1's media to the slot it
1733 came from', other than to explicitly use that
1734 slot number as the destination.AB

1772 Handling removable disks
1774 From: Karl Cunningham <karlc@keckec.com>
1776 My backups are only to hard disk these days, in removable bays. This is my
1777 idea of how a backup to hard disk would work more smoothly. Some of these
1778 things Bacula does already, but I mention them for completeness. If others
1779 have better ways to do this, I'd like to hear about it.
1781 1. Accommodate several disks, rotated similar to how tapes are. Identified
1782 by partition volume ID or perhaps by the name of a subdirectory.
1783 2. Abort & notify the admin if the wrong disk is in the bay.
1784 3. Write backups to different subdirectories for each machine to be backed
1786 4. Volumes (files) get created as needed in the proper subdirectory, one
1788 5. When a disk is recycled, remove or zero all old backup files. This is
1789 important as the disk being recycled may be close to full. This may be
1790 better done manually since the backup files for many machines may be
1791 scattered in many subdirectories.
1796 - Why the heck doesn't bacula drop root priviledges before connecting to
1798 - Look at using posix_fadvise(2) for backups -- see bug #751.
1799 Possibly add the code at findlib/bfile.c:795
1800 /* TCP socket options */
1801 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1802 - Fix bnet_connect() code to set a timer and to use time to
1804 - Implement 4th argument to make_catalog_backup that passes hostname.
1805 - Test FIFO backup/restore -- make regression
1806 - Please mount volume "xxx" on Storage device ... should also list
1807 Pool and MediaType in case user needs to create a new volume.
1808 - On restore add Restore Client, Original Client.

1817 - Check if gnome-console works with TLS.
1818 - the director seg faulted when I omitted the pool directive from a
1819 job resource. I was experimenting and thought it redundant that I had
1820 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1821 apparently not. This happened when I removed the pool directive and
1822 started the director.
1823 - Add Where: client:/.... to restore job report.
1824 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1825 does the right thing.
1826 - FD-SD quick disconnect
1827 - Building the in memory restore tree is slow.
