14 - package sg3-utils, program sg_map
15 - !!! Cannot restore two jobs a the same time that were
16 written simultaneously unless they were totally spooled.
17 - Document cleaning up the spool files:
18 db, pid, state, bsr, mail, conmsg, spool
19 - Document the multiple-drive-changer.txt script.
20 - Pruning with Admin job.
21 - Does WildFile match against full name? Doc.
22 - %d and %v only valid on Director, not for ClientRunBefore/After.
23 - During tests with the 260 char fix code, I found one problem:
24 if the system "sees" a long path once, it seems to forget it's
25 working drive (e.g. c:\), which will lead to a problem during
26 the next job (create bootstrap file will fail). Here is the
27 workaround: specify absolute working and pid directory in
28 bacula-fd.conf (e.g. c:\bacula\working instead of
30 - Document techniques for restoring large numbers of files.
31 - Document setting my.cnf to big file usage.
32 - Correct the Include syntax in the m4.xxx files in examples/conf
33 - Document all the little details of setting up certificates for
34 the Bacula data encryption code.
35 - Document more precisely how to use master keys -- especially
36 for disaster recovery.

43 - Add external command to lookup hostname (eg nmblookup timmy-win7)
45 querying gato on 127.255.255.255
46 querying gato on 192.168.1.255
51 - Possibly allow SD to spool even if a tape is not mounted.
52 - How to sync remote offices.
54 - Backup up windows system state
55 - Complete Job restart
56 - Look at rsysnc for incremental updates and dedupping
57 - Implement rwlock() for SD that takes why and can_steal to replace
58 existing block/lock mechanism. rlock() would allow multiple readers
59 wlock would allow only one writer.
60 - For Windows disaster recovery see http://unattended.sf.net/
61 - Add "before=" "olderthan=" to FileSet for doing Base of
63 - Show files/second in client status output.
64 - Don't attempt to restore from "Disabled" Volumes.
65 - Have SD compute MD5 or SHA1 and compare to what FD computes.
66 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
67 actual data on the Volume and compare it.
68 - Remove queue.c code.
69 - Implement multiple jobid specification for the cancel command,
70 similar to what is permitted on the update slots command.
71 - Ensure that the SD re-reads the Media record if the JobFiles
72 does not match -- it may have been updated by another job.
73 - Add MD5 or SHA1 check in SD for data validation
74 - When reserving a device to read, check to see if the Volume
75 is already in use, if so wait. Probably will need to pass the
76 Volume. See bug #1313. Create a regression test to simulate
77 this problem and see if VolumePollInterval fixes it. Possibly turn
82 - Why no error message if restore has no permission on the where
84 - Possibly allow manual "purge" to purge a Volume that has not
85 yet been written (even if FirstWritten time is zero) see ua_purge.c
87 - Add disk block detection bsr code (make it work).
89 - Detect deadlocks in reservations.
91 - Add list during dump
92 - Add in plugin code flag
93 - Add bRC_EndJob -- stops more calls to plugin this job
94 - Add bRC_Term (unload plugin)
95 - remove time_t from Jmsg and use utime_t?
96 - Deadlock detection, watchdog sees if counter advances when jobs are
97 running. With debug on, can do a "status" command.
98 - User options for plugins.
99 - Pool Storage override precedence over command line.
100 - Autolabel only if Volume catalog information indicates tape not
101 written. This will avoid overwriting a tape that gets an I/O
102 error on reading the volume label.
103 - I/O error, SD thinks it is not the right Volume, should check slot
104 then disable volume, but Asks for mount.
105 - Can be posible modify package to create and use configuration files in
110 /etc/bacula/bacula-dir.conf
111 /etc/bacula/conf.d/pools.conf
112 /etc/bacula/conf.d/clients.conf
113 /etc/bacula/conf.d/storages.conf
115 and into bacula-dir.conf file include
117 @/etc/bacula/conf.d/pools.conf
118 @/etc/bacula/conf.d/clients.conf
119 @/etc/bacula/conf.d/storages.conf
120 - Possibly add an Inconsistent state when a Volume is in error
122 - Fix #ifdefing so that smartalloc can be disabled. Check manual
123 -- the default is enabled.
124 - Dangling softlinks are not restored properly. For example, take a
125 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
126 move the directory to another machine where the file /usr/share/autoconf does
127 not exist, back it up, then try a full restore. It fails.
128 - Softlinks that point to non-existent file are not restored in restore all,
129 but are restored if the file is individually selected. BUG!
131 - Prune by Job Level (Full, Differential, Incremental)
132 - modify pruning to keep a fixed number of versions of a file,
134 - the cd-command should allow complete paths
135 i.e. cd /foo/bar/foo/bar
136 -> if a customer mails me the path to a certain file,
137 its faster to enter the specified directory
138 - Make tree walk routines like cd, ls, ... more user friendly
139 by handling spaces better.
140 - When doing a restore, if the user does an "update slots"
141 after the job started in order to add a restore volume, the
142 values prior to the update slots will be put into the catalog.
143 Must retrieve catalog record merge it then write it back at the
144 end of the restore job, if we want to do this right.
148 MA = (last_MA * 3 + rate) / 4
149 rate = (bytes - last_bytes) / (runtime - last_runtime)
151 - Add a recursive mark command (rmark) to restore.
152 - Look at simplifying File exclusions.
154 - Separate Files and Directories in catalog
155 - Create FileVersions table
156 - finish implementation of fdcalled -- see ua_run.c:105
157 - Fix problem in postgresql.c in my_postgresql_query, where the
158 generation of the error message doesn't differentiate result==NULL
159 and a bad status from that result. Not only that, the result is
160 cleared on a bail_out without having generated the error message.
161 - Implement SDErrors (must return from SD)
162 - Implement continue spooling while despooling.
163 - Remove all install temp files in Win32 PLUGINSDIR.
164 - No where in restore causes kaboom.
165 - Performance: multiple spool files for a single job.
166 - Performance: despool attributes when despooling data (problem
167 multiplexing Dir connection).
168 - Implement wait_for_sysop() message display in wait_for_device(), which
169 now prints warnings too often.
170 - Ensure that each device in an Autochanger has a different
172 - Look at sg_logs -a /dev/sg0 for getting soft errors.
173 - btape "test" command with Offline on Unmount = yes
175 This test is essential to Bacula.
177 I'm going to write one record in file 0,
178 two records in file 1,
179 and three records in file 2

186 - Encryption -- email from Landon
187 > The backup encryption algorithm is currently not configurable, and is
188 > set to AES_128_CBC in src/filed/backup.c. The encryption code
189 > supports a number of different ciphers (as well as adding arbitrary
190 > new ones) -- only a small bit of code would be required to map a
191 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is
192 > interested in implementing this functionality.
194 - Add the OS version back to the Win32 client info.
195 - Restarted jobs have a NULL in the from field.
196 - Modify SD status command to indicate when the SD is writing
197 to a DVD (the device is not open -- see bug #732).
198 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
199 and possibly changing the blobs into varchar.
200 - Test Volume compatibility between machine architectures
201 - Encryption documentation
204 - Migration from other vendors
208 - Backup conf/exe (all daemons)

222 - Look at: http://tech.groups.yahoo.com/group/cfg2html
223 and http://www.openeyet.nl/scc/ for managing customer changes
227 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
229 - Maximum number of scratch volumes
231 - Next Pool (already have)
232 - Reclamation threshold
234 - Reuse delay (after all files purged from volume before it can be used)
235 - Copy Pool = xx, yyy (or multiple lines).
237 - Allow pool selection during restore.
239 - Average tape size from Eric
240 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg

251 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
252 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
254 - Despool attributes in separate thread
257 - Check why restore repeatedly sends Rechdrs between
258 each data chunk -- according to James Harper 9Jan07.
261 - More intelligent re-run
262 - Incremental backup -- rsync, Stow
264 - Make Bacula by default not backup tmpfs, procfs, sysfs, ...
265 - Fix hardlinked immutable files when linking a second file, the
266 immutable flag must be removed prior to trying to link it.
267 - Change dbcheck to tell users to use native tools for fixing
268 broken databases, and to ensure they have the proper indexes.
269 - add udev rules for Bacula devices.
270 - If a job terminates, the DIR connection can close before the
271 Volume info is updated, leaving the File count wrong.
272 - Look at why SIGPIPE during connection can cause seg fault in
273 writing the daemon message, when Dir dropped to bacula:bacula
274 - Look at zlib 32 => 64 problems.
275 - Fix bextract to restore ACLs, or better yet, use common routines.
276 - New dot commands from Arno.
277 .show device=xxx lists information from one storage device, including
278 devices (I'm not even sure that information exists in the DIR...)
279 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
280 better machine-readable output like "Ok" or "Error busy"
281 .move eject device=xxx toslot=yyy the same as above, but with a new
282 target slot. The catalog should be updated accordingly.
283 .move transfer device=xxx fromslot=yyy toslot=zzz

456 If this is not a blank tape, try unmounting and remounting the Volume.
458 - http://www.dwheeler.com/essays/commercial-floss.html
459 - Add VolumeLock to prevent all but lock holder (SD) from updating
460 the Volume data (with the exception of VolumeState).
461 - The btape fill command does not seem to use the Autochanger
462 - Make Windows installer default to system disk drive.
463 - Look at using ioctl(FIOBMAP, ...) on Linux, and
464 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
465 Win32 for sparse files.

468 - Directive: at <event> "command"
469 - Command: pycmd "command" generates "command" event. How to
470 attach to a specific job?
471 - run_cmd() returns int should return JobId_t
472 - get_next_jobid_from_list() returns int should return JobId_t
473 - Document export LDFLAGS=-L/usr/lib64
474 - Network error on Win32 should set Win32 error code.
475 - What happens when you rename a Disk Volume?
476 - Job retention period in a Pool (and hence Volume). The job would
478 - Add Win32 FileSet definition somewhere
479 - Look at fixing restore status stats in SD.
480 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
481 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
482 - Implement a mode that says when a hard read error is
483 encountered, read many times (as it currently does), and if the
484 block cannot be read, skip to the next block, and try again. If
485 that fails, skip to the next file and try again, ...
487 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
488 insert into LevelType (LevelType,LevelTypeLong) values
492 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
493 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
494 see if it become stable and I just have to supervise
496 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
497 PoolId, and when it is empty remove it.
499 - Allow Check Labels to be used with Bacula labels.
500 - "Resuming" a failed backup (lost line for example) by using the
501 failed backup as a sort of "base" job.
503 - Email to the user when the tape is about to need changing x
504 days before it needs changing.
505 - Command to show next tape that will be used for a job even
506 if the job is not scheduled.
507 - From: Arunav Mandal <amandal@trolltech.com>
508 1. When jobs are running and bacula for some reason crashes or if I do a
509 restart it remembers and jobs it was running before it crashed or restarted
510 as of now I loose all jobs if I restart it.
512 2. When spooling and in the midway if client is disconnected for instance a
513 laptop bacula completely discard the spool. It will be nice if it can write
514 that spool to tape so there will be some backups for that client if not all.
516 3. We have around 150 clients machines it will be nice to have a option to
517 upgrade all the client machines bacula version automatically.
519 4. Atleast one connection should be reserved for the bconsole so at heavy load
520 I should connect to the director via bconsole which at sometimes I can't
522 5. Another most important feature that is missing, say at 10am I manually
523 started backup of client abc and it was a full backup since client abc has
524 no backup history and at 10.30am bacula again automatically started backup of
525 client abc as that was in the schedule. So now we have 2 multiple Full
526 backups of the same client and if we again try to start a full backup of
527 client backup abc bacula won't complain. That should be fixed.
529 - regardless of the retention period, Bacula will not prune the
530 last Full, Diff, or Inc File data until a month after the
531 retention period for the last Full backup that was done.
532 - update volume=xxx --- add status=Full
533 - Remove old spool files on startup.
534 - Exclude SD spool/working directory.
535 - Refuse to prune last valid Full backup. Same goes for Catalog.
537 - Make a callback when Rerun failed levels is called.
538 - Give Python program access to Scheduled jobs.
539 - Add setting Volume State via Python.
540 - Python script to save with Python, not save, save with Bacula.
541 - Python script to do backup.
543 - Change the Priority, Client, Storage, JobStatus (error)
544 at the start of a job.
545 - Why is SpoolDirectory = /home/bacula/spool; not reported
546 as an error when writing a DVD?
547 - Make bootstrap file handle multiple MediaTypes (SD)
548 - Remove all old Device resource code in Dir and code to pass it
549 back in SD -- better, rework it to pass back device statistics.
550 - Check locking of resources -- be sure to lock devices where previously
551 resources were locked.
552 - The last part is left in the spool dir.
555 - In restore don't compare byte count on a raw device -- directory
556 entry does not contain bytes.
559 - Max Vols limit in Pool off by one?
560 - Implement Files/Bytes,... stats for restore job.
561 - Implement Total Bytes Written, ... for restore job.
562 - Despool attributes simultaneously with data in a separate
563 thread, rejoined at end of data spooling.
564 - 7. Implement new Console commands to allow offlining/reserving drives,
565 and possibly manipulating the autochanger (much asked for).
566 - Add start/end date editing in messages (%t %T, %e?) ...
567 - Add ClientDefs similar to JobDefs.
568 - Print more info when bextract -p accepts a bad block.
569 - Fix FD JobType to be set before RunBeforeJob in FD.
570 - Look at adding full Volume and Pool information to a Volume
571 label so that bscan can get *all* the info.
572 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
573 and there is only one volume in the pool, refuse to do it -- otherwise
574 he fills the Volume, then immediately starts reusing it.
575 - Implement copies and stripes.
576 - Add history file to console.
577 - Each file on tape creates a JobMedia record. Peter has 4 million
578 files spread over 10000 tape files and four tapes. A restore takes
579 16 hours to build the restore list.
580 - Add and option to check if the file size changed during backup.
581 - Make sure SD deletes spool files on error exit.
582 - Delete old spool files when SD starts.
583 - When labeling tapes, if you enter 000026, Bacula uses
584 the tape index rather than the Volume name 000026.
585 - Add offline tape command to Bacula console.
587 Enter MediaId or Volume name: 32
588 Enter new Volume name: DLT-20Dec04
589 Automatically selected Pool: Default
590 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

598 Do not forget to mount the drive!!!
599 - Bug: if a job is manually scheduled to run later, it does not appear
600 in any status report and cannot be cancelled.
605 How about introducing a Type = MgmtPolicy job type? That job type would
606 be responsible for scanning the Bacula environment looking for specific
607 conditions, and submitting the appropriate jobs for implementing said
611 Name = "Migration-Policy"
613 Policy Selection Job Type = Migrate
614 Scope = "<keyword> <operator> <regexp>"
615 Threshold = "<keyword> <operator> <regexp>"
616 Job Template = <template-name>
619 Where <keyword> is any legal job keyword, <operator> is a comparison
620 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
621 appropriate regexp. I could see an argument for Scope and Threshold
622 being SQL queries if we want to support full flexibility. The
623 Migration-Policy job would then get scheduled as frequently as a site
624 felt necessary (suggested default: every 15 minutes).
629 Name = "Migration-Policy"
631 Policy Selection Job Type = Migration
633 Threshold = "Migration Selection Type = LowestUtil"
634 Job Template = "MigrationTemplate"
637 would select all pools for examination and generate a job based on
638 MigrationTemplate to automatically select the volume with the lowest
639 usage and migrate it's contents to the nextpool defined for that pool.
641 This policy abstraction would be really handy for adjusting the behavior
642 of Bacula according to site-selectable criteria (one thing that pops
643 into mind is Amanda's ability to automatically adjust backup levels
644 depending on various criteria).
650 - Add Pool/Storage override regression test.
651 - Add delete JobId to regression.
652 - Add a regression test for dbcheck.
653 - New test to add bscan to four-concurrent-jobs regression,
654 i.e. after the four-concurrent jobs zap the
655 database as is done in the bscan-test, then use bscan to
656 restore the database, do a restore and compare with the
658 - Add restore of specific JobId to regression (item 3
659 on the restore prompt)
660 - Add IPv6 to regression
661 - Add database test to regression. Test each function like delete,
664 - AntiVir can slow down backups on Win32 systems.
665 - Win32 systems with FAT32 can be much slower than NTFS for
666 more than 1000 files per directory.
670 - A HOLD command to stop all jobs from starting.
671 - A PAUSE command to pause all running jobs ==> release the
673 - Media Type = LTO,LTO-2,LTO-3
674 Media Type Read = LTO,LTO2,LTO3
675 Media Type Write = LTO2, LTO3
677 === From Carsten Menke <bootsy52@gmx.net>
679 Following is a list of what I think in the situations where I'm faced with,
680 could be a usefull enhancement to bacula, which I'm certain other users will
681 benefit from as well.
683 1. NextJob/NextJobs Directive within a Job Resource in the form of
684 NextJobs = job1,job2.
687 I currently solved the problem with running multiple jobs each after each
688 by setting the Max Wait Time for a job to 8 hours, and give
689 the jobs different Priorities. However, there scenarios where
690 1 Job is directly depending on another job, so if the former job fails,
691 the job after it needn't to be run
692 while maybe other jobs should run despite of that
695 A Backup Job and a Verify job, if the backup job fails there is no need to run
696 the verify job, as the backup job already failed. However, one may like
697 to backup the Catalog to disk despite of that the main backup job failed.
700 I see that this is related to the Event Handlers which are on the ToDo
701 list, also it is maybe a good idea to check for the return value and
702 execute different actions based on the return value
705 3. offline capability to bconsole
708 Currently I use a script which I execute within the last Job via the
709 RunAfterJob Directive, to release and eject the tape.
710 So I have to call bconsole "release=Storage-Name" and afterwards
711 mt -f /dev/nst0 eject to get the tape out.
713 If I have multiple Storage Devices, than these may not be /dev/nst0 and
714 I have to modify the script or call it with parameters etc.
715 This would actually not be needed, as everything is already defined
716 in bacula-sd.conf and if I can invoke bconsole with the
717 storage name via $1 in the script than I'm done and information is
720 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
724 For the reason mentioned in 3. to have the ability to call a
725 script with /scripts/foobar %s and in the script use $1
726 to pass the Storage Name to bconsole
728 5. Setting Volume State within a Job Resource
731 Instead of using "Maximum Volume Jobs" in the Pool Resource,
732 I would have the possibilty to define
733 in a Job Resource that after this certain job is run, the Volume State
734 should be set to "Volume State = Used", this give more flexibility (IMHO).
736 7. OK, this is evil, probably bound to security risks and maybe not possible
737 due to the design of bacula.
739 Implementation of Backtics ( `command` ) for shell comand execution to
740 the "Label Format" Directive.
744 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
745 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
746 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
747 the localized name for the day of the week appended to the
748 format string. Then I have the tape labeled automatically with weekday
749 name in the correct language.
751 - Make output from status use html table tags for nicely
752 presenting in a browser.
753 - Browse generations of files.
754 - I've seen an error when my catalog's File table fills up. I
755 then have to recreate the File table with a larger maximum row
756 size. Relevant information is at
757 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
758 "Installing and Configuring MySQL" chapter should talk a bit
759 about this potential problem, and recommend a solution.
760 - Want speed of writing to tape while despooling.
761 - Supported autochanger:
769 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
770 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
771 - Add regex from http://www.pcre.org to Bacula for Win32.
772 - Use only shell tools no make in CDROM package.
773 - Include within include does it work?
774 - Implement a Pool of type Cleaning?
775 - Think about making certain database errors fatal.
776 - Look at correcting the time jump in the scheduler for daylight
777 savings time changes.
778 - Check dates entered by user for correctness (month/day/... ranges)
779 - Compress restore Volume listing by date and first file.
780 - Look at patches/bacula_db.b2z postgresql that loops during restore.
782 - Perhaps add read/write programs and/or plugins to FileSets.
783 - How to handle backing up portables ...
786 Documentation to do: (any release a little bit at a time)
787 - Doc to do unmount before removing magazine.
788 - Alternative to static linking "ldd prog" save all binaries listed,
789 restore them and point LD_LIBRARY_PATH to them.
790 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
791 - Document query file format.
792 - Add more documentation for bsr files.
793 - Document problems with Verify and pruning.
794 - Document how to use multiple databases.
795 - VXA drives have a "cleaning required"
796 indicator, but Exabyte recommends preventive cleaning after every 75
799 In this context, it should be noted that Exabyte has a command-line
800 vxatool utility available for free download. (The current version is
801 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
802 test the drive, unload tapes, change drive settings, flash new firmware,
804 Of particular interest in this context is that vxatool <device> -i will
805 report, among other details, the time since last cleaning in tape motion
806 minutes. This information can be retrieved (and settings changed, for
807 that matter) through the generic-SCSI device even when Bacula has the
808 regular tape device locked. (Needless to say, I don't recommend
809 changing tape settings while a job is running.)
810 - Lookup HP cleaning recommendations.
811 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
812 - Document doing table repair
815 ===================================
816 - Add macro expansions in JobDefs.
817 Run Before Job = "SomeFile %{Level} %{Client}"
818 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
819 - Use non-blocking network I/O but if no data is available, use
821 - Use gather write() for network I/O.
822 - Autorestart on crash.
823 - Add bandwidth limiting.
824 - When an error in input occurs and conio beeps, you can back
825 up through the prompt.
826 - Detect fixed tape block mode during positioning by looking at
827 block numbers in btape "test". Possibly adjust in Bacula.
828 - Fix list volumes to output volume retention in some other
829 units, perhaps via a directive.
830 - If you use restore replace=never, the directory attributes for
831 non-existent directories will not be restored properly.
833 - see lzma401.zip in others directory for new compression
835 - Allow the user to select JobType for manual pruning/purging.
836 - bscan does not put first of two volumes back with all info in
838 - Figure out how to make named console messages go only to that
839 console and to the non-restricted console (new console class?).
840 - Make restricted console prompt for password if *ask* is set or
841 perhaps if password is undefined.
842 - Implement "from ISO-date/time every x hours/days/weeks/months" in
845 ==== from Marc Schoechlin
846 - the help-command should be more verbose
847 (it should explain the paramters of the different
849 -> its time-comsuming to consult the manual anytime
850 you need a special parameter
851 -> maybe its more easy to maintain this, if the
852 descriptions of that commands are outsourced to
854 - if the password is not configured in bconsole.conf
855 you should be asked for it.
856 -> sometimes you like to do restore on a customer-machine
857 which shouldnt know the password for bacula.
858 -> adding the password to the file favours admins
859 to forget to remove the password after usage
861 the protection of that file is less important
862 - long-listed-output of commands should be scrollable
863 like the unix more/less-command does
864 -> if someone runs 200 and more machines, the lists could
865 be a little long and complex
866 - command-output should be shown column by column
867 to reduce scrolling and to increase clarity
869 - lsmark should list the selected files with full
871 - wildcards for selecting and file and directories would be nice
872 - any actions should be interuptable with STRG+C
873 - command-expansion would be pretty cool
875 - When the replace Never option is set, new directory permissions
876 are not restored. See bug 213. To fix this requires creating a
877 list of newly restored directories so that those directory
878 permissions *can* be restored.
879 - Add prune all command
880 - Document fact that purge can destroy a part of a restore by purging
881 one volume while others remain valid -- perhaps mark Jobs.
882 - Add multiple-media-types.txt
883 - look at mxt-changer.html
884 - Make ? do a help command (no return needed).
885 - Implement restore directory.
886 - Document streams and how to implement them.
887 - Try not to re-backup a file if a new hard link is added.
888 - Add feature to backup hard links only, but not the data.
889 - Fix stream handling to be simpler.
890 - Add Priority and Bootstrap to Run a Job.
891 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
893 - Remove View FileSet button from Run a Job dialog.
894 - Handle prompt for restore job at end of Restore command.
895 - Add display of total selected files to Restore window.
896 - Add tree pane to left of window.
897 - Add progress meter.
898 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
899 - Add message to user to check for fixed block size when the forward
900 space test fails in btape.
901 - When unmarking a directory check if all files below are unmarked and
902 then remove the + flag -- in the restore tree.
903 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
904 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
905 - Revisit the question of multiple Volumes (disk) on a single device.
906 - Add a block copy option to bcopy.
907 - Fix "llist jobid=xx" where no fileset or client exists.
908 - For each job type (Admin, Restore, ...) require only the really necessary
909 fields.- Pass Director resource name as an option to the Console.
910 - Add a "batch" mode to the Console (no unsolicited queries, ...).
911 - Allow browsing the catalog to see all versions of a file (with
912 stat data on each file).
913 - Restore attributes of directory if replace=never set but directory
915 - Use SHA1 on authentication if possible.
916 - See comtest-xxx.zip for Windows code to talk to USB.
917 - Add John's appended files:
918 Appended = { /files/server/logs/http/*log }
919 and such files would be treated as follows.On a FULL backup, they would
920 be backed up like any other file.On an INCREMENTAL backup, where a
921 previous INCREMENTAL or FULL was already in thecatalogue and the length
922 of the file wasgreater than the length of the last backup, only thedata
923 added since the last backup will be dumped.On an INCREMENTAL backup, if
924 the length of the file is less than thelength of the file with the same
925 name last backed up, the completefile is dumped.On Windows systems, with
926 creation date of files, we can be evensmarter about this and not count
927 entirely upon the length.On a restore, the full and all incrementals
928 since it will beapplied in sequence to restore the file.
929 - Check new HAVE_WIN32 open bits.
930 - Check if the tape has moved before writing.
931 - Handling removable disks -- see below:
932 - Add FromClient and ToClient keywords on restore command (or
933 BackupClient RestoreClient).
934 - Implement a JobSet, which groups any number of jobs. If the
935 JobSet is started, all the jobs are started together.
936 Allow Pool, Level, and Schedule overrides.
937 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
938 correctly for multiple simultaneous jobs.
939 - Implement the Media record flag that indicates that the Volume does disk
941 - Fix fast block rejection (stored/read_record.c:118). It passes a null
942 pointer (rec) to try_repositioning().
943 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
944 which would take precidence over the Catalog "JobRetention".
945 - Implement Label Format in Add and Label console commands.
946 - Put email tape request delays on one or more variables. User wants
947 to cancel the job after a certain time interval. Maximum Mount Wait?
948 - Job, Client, Device, Pool, or Volume?
949 Is it possible to make this a directive which is *optional* in multiple
950 resources, like Level? If so, I think I'd make it an optional directive
951 in Job, Client, and Pool, with precedence such that Job overrides Client
952 which in turn overrides Pool.
954 - New Storage specifications:
955 - Want to write to multiple storage devices simultaneously
956 - Want to write to multiple storage devices sequentially (in one job)
957 - Want to read/write simultaneously
958 - Key is MediaType -- it must match
960 Passed to SD as a sort of BSR record called Storage Specification
964 MediaType -> Next MediaType
966 Device -> Next Device
968 Allow multiple Storage specifications
976 Allow Multiple Pool specifications (note, Pool currently
978 Allow Multiple MediaType specifications in Dir conf
979 Allow Multiple Device specifications in Dir conf
980 Perhaps keep this in a single SSR
981 Tie a Volume to a specific device by using a MediaType that
982 is contained in only one device.
983 In SD allow Device to have Multiple MediaTypes
985 - Ideas from Jerry Scharf:
986 First let's point out some big pluses that bacula has for this
988 more importantly it's active. Thank you so much for that
989 even more important, it's not flaky
990 it has an open access catalog, opening many possibilities
991 it's pushing toward heterogeneous systems capability
993 Macintosh file client
994 working bare iron recovery for windows
995 the option for inc/diff backups not reset on fileset revision
996 a) use both change and inode update time against base time
997 b) do the full catalog check (expensive but accurate)
998 sizing guide (how much system is needed to back up N systems/files)
999 consultants on using bacula in building a disaster recovery system
1000 an integration guide
1001 or how to get at fancy things that one could do with bacula
1002 logwatch code for bacula logs (or similar)
1003 support for Oracle database ??
1005 - Look at adding SQL server and Exchange support for Windows.
1006 - Add progress of files/bytes to SD and FD.
1007 - do a "messages" before the first prompt in Console
1008 - Client does not show busy during Estimate command.
1009 - Implement Console mtx commands.
1010 - Implement a Mount Command and an Unmount Command where
1011 the users could specify a system command to be performed
1012 to do the mount, after which Bacula could attempt to
1013 read the device. This is for Removeable media such as a CDROM.
1014 - Most likely, this mount command would be invoked explicitly
1015 by the user using the current Console "mount" and "unmount"
1016 commands -- the Storage Daemon would do the right thing
1017 depending on the exact nature of the device.
1018 - As with tape drives, when Bacula wanted a new removable
1019 disk mounted, it would unmount the old one, and send a message
1020 to the user, who would then use "mount" as described above
1021 once he had actually inserted the disk.
1022 - Implement dump/print label to UA
1023 - Spool to disk only when the tape is full, then when a tape is hung move
1025 - bextract is sending everything to the log file ****FIXME****
1026 - Allow multiple Storage specifications (or multiple names on
1027 a single Storage specification) in the Job record. Thus a job
1028 can be backed up to a number of storage devices.
1029 - Implement some way for the File daemon to contact the Director
1030 to start a job or pass its DHCP obtained IP number.
1031 - Implement a query tape prompt/replace feature for a console
1032 - Make sure that Bacula rechecks the tape after the 20 min wait.
1033 - Set IO_NOWAIT on Bacula TCP/IP packets.
1034 - Try doing a raw partition backup and restore by mounting a
1036 - From Lars Kellers:
1037 Yes, it would allow to highly automatic the request for new tapes. If a
1038 tape is empty, bacula reads the barcodes (native or simulated), and if
1039 an unused tape is found, it runs the label command with all the
1040 necessary parameters.
1042 By the way can bacula automatically "move" an empty/purged volume say
1043 in the "short" pool to the "long" pool if this pool runs out of volume
1045 - What to do about "list files job=xxx".
1046 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1047 file descriptor leak in Bacula.
1048 - Can we dynamically change FileSets?
1049 - If pool specified to label command and Label Format is specified,
1050 automatically generate the Volume name.
1051 - Add ExhautiveRestoreSearch
1052 - Look at the possibility of loading only the necessary
1053 data into the restore tree (i.e. do it one directory at a
1054 time as the user walks through the tree).
1055 - Possibly use the hash code if the user selects all for a restore command.
1056 - Fix "restore all" to bypass building the tree.
1057 - Prohibit backing up archive device (findlib/find_one.c:128)
1058 - Implement Release Device in the Job resource to unmount a drive.
1059 - Implement Acquire Device in the Job resource to mount a drive,
1060 be sure this works with admin jobs so that the user can get
1061 prompted to insert the correct tape. Possibly some way to say to
1062 run the job but don't save the files.
1063 - Make things like list where a file is saved case independent for
1065 - Implement a Recycle command
1066 - From Phil Stracchino:
1067 It would probably be a per-client option, and would be called
1068 something like, say, "Automatically purge obsoleted jobs". What it
1069 would do is, when you successfully complete a Differential backup of a
1070 client, it would automatically purge all Incremental backups for that
1071 client that are rendered redundant by that Differential. Likewise,
1072 when a Full backup on a client completed, it would automatically purge
1073 all Differential and Incremental jobs obsoleted by that Full backup.
1074 This would let people minimize the number of tapes they're keeping on
1075 hand without having to master the art of retention times.
1076 - When doing a Backup send all attributes back to the Director, who
1077 would then figure out what files have been deleted.
1078 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1079 explicit permission to do so. It should also mark the tape in error
1080 if there is an error.
1081 - Cancel waiting for Client connect in SD if FD goes away.
1083 - Implement timeout in response() when it should come quickly.
1084 - Implement a Slot priority (loaded/not loaded).
1085 - Implement "vacation" Incremental only saves.
1086 - Implement create "FileSet"?
1087 - Add prefixlinks to where or not where absolute links to FD.
1088 - Issue message to mount a new tape before the rewind.
1089 - Simplified client job initiation for portables.
1090 - If SD cannot open a drive, make it periodically retry.
1091 - Add more of the config info to the tape label.
1093 - Refine SD waiting output:
1094 Device is being positioned
1095 > Device is being positioned for append
1096 > Device is being positioned to file x
1098 - Figure out some way to estimate output size and to avoid splitting
1099 a backup across two Volumes -- this could be useful for writing CDROMs
1100 where you really prefer not to have it split -- not serious.
1101 - Make bcopy read through bad tape records.
1102 - Program files (i.e. execute a program to read/write files).
1103 Pass read date of last backup, size of file last time.
1104 - Add Signature type to File DB record.
1105 - CD into subdirectory when open()ing files for backup to
1106 speed up things. Test with testfind().
1107 - Priority job to go to top of list.
1108 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1109 - Implement some way for the Console to dynamically create a job.
1110 - Solaris -I on tar for include list
1111 - Need a verbose mode in restore, perhaps to bsr.
1112 - bscan without -v is too quiet -- perhaps show jobs.
1113 - Add code to reject whole blocks if not wanted on restore.
1114 - Check if we can increase Bacula FD priorty in Win2000
1115 - Check if both CatalogFiles and UseCatalog are set to SD.
1116 - Possibly add email to Watchdog if drive is unmounted too
1117 long and a job is waiting on the drive.
1118 - After unmount, if restore job started, ask to mount.
1119 - Add UA rc and history files.
1120 - put termcap (used by console) in ./configure and
1121 allow -with-termcap-dir.
1122 - Fix Autoprune for Volumes to respect need for full save.
1123 - Compare tape to Client files (attributes, or attributes and data)
1124 - Make all database Ids 64 bit.
1125 - Allow console commands to detach or run in background.
1126 - Add SD message variables to control operator wait time
1127 - Maximum Operator Wait
1128 - Minimum Message Interval
1129 - Maximum Message Interval
1130 - Send Operator message when cannot read tape label.
1131 - Verify level=Volume (scan only), level=Data (compare of data to file).
1132 Verify level=Catalog, level=InitCatalog
1134 - Add keyword search to show command in Console.
1135 - Events : tape has more than xxx bytes.

1164 - Autolabel should be specified by DIR instead of SD.
1166 - Add media capacity
1167 - AutoScan (check checksum of tape)
1168 - Format command = "format /dev/nst0"
1172 - Seek resolution (usually corresponds to buffer size)
1173 - EODErrorCode=ENOSPC or code
1174 - Partial Read error code
1175 - Partial write error code
1176 - Nonformatted read error
1177 - Nonformatted write error
1178 - WriteProtected error
1182 - IgnoreCloseErrors=yes
1192 - Write a Storage daemon that uses pipes and
1193 standard Unix programs to write to the tape.
1195 - Need something that monitors the JCR queue and
1196 times out jobs by asking the deamons where they are.
1197 - Verify from Volume
1198 - Need report class for messages. Perhaps
1199 report resource where report=group of messages
1200 - enhance scan_attrib and rename scan_jobtype, and
1201 fill in code for "since" option
1202 - Director needs a time after which the report status is sent
1203 anyway -- or better yet, a retry time for the job.
1204 - Don't reschedule a job if previous incarnation is still running.
1205 - Some way to automatically backup everything is needed????
1206 - Need a structure for pending actions:
1208 - termination status (part of buffered msgs?)
1210 Read, Write, Clean, Delete
1211 - Login to Bacula; Bacula users with different permissions:
1212 owner, group, user, quotas
1213 - Store info on each file system type (probably in the job header on tape.
1214 This could be the output of df; or perhaps some sort of /etc/mtab record.

1219 Subject: RE: [Bacula-users] future large programming jobs
1220 Date: Thu, 26 Feb 2004 11:34:54 -0600
1222 I noticed the subject thread and thought I would offer the following
1223 merely as sources of ideas, i.e. something to think about, not even as
1224 strong as a request. In my former life (before retiring) I often
1225 dealt with backups and storage management issues/products as a
1226 developer and as a consultant. I am currently migrating my personal
1227 network from amanda to bacula specifically because of the ability to
1228 cross media boundaries during storing backups.
1229 Are you familiar with the commercial product called ADSM (I think IBM
1230 now sells it under the Tivoli label)? It has a couple of interesting
1231 ideas that may apply to the following topics.
1233 1. Migration: Consider that when you need to restore a system, there
1234 may be pressure to hurry. If all the information for a single client
1235 can eventually end up on the same media (and in chronological order),
1236 the restore is facillitated by not having to search past information
1237 from other clients. ADSM has the concept of "client affinity" that
1238 may be associated with it's storage pools. It seems to me that this
1239 concept (as an optional feature) might fit in your architecture for
1242 ADSM also has the concept of defining one or more storage pools as
1243 "copy pools" (almost mirrors, but only in the sense of contents).
1244 These pools provide the ability to have duplicte data stored both
1245 onsite and offsite. The copy process can be scheduled to be handled
1246 by their storage manager during periods when there is no backup
1247 activity. Again, the migration process might be a place to consider
1248 implementing something like this.

1261 This is the goal. In the first step (before events), you simply
1263 the Migration to tape later.
1265 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1266 the database. Once a file (unique by path and metadata such as dates,
1267 size, ownership, etc.) is in a copy pool, no more copies are made. In
1268 other words, when you start ADSM, it begins like your concept of a
1269 base job. After that it is in the "incremental" mode. You can
1270 configure the number of "generations" of files to be retained, plus a
1271 retention date after which even old generations are purged. The
1272 database tracks the contents of media and projects the percentage of
1273 each volume that is valid. When the valid content of a volume drops
1274 below a configured percentage, the valid data are migrated to another
1275 volume and the old volume is marked as empty. Note, this requires
1276 ADSM to have an idea of the contents of a client, i.e. marking the
1277 database when an existing file was deleted, but this would solve your
1278 issue of restoring a client without restoring deleted files.
1280 This is pretty far from what bacula now does, but if you are going to
1281 rip things up for Base jobs,.....
1282 Also, the benefits of this are huge for very large shops, especially
1283 with media robots, but are a pain for shops with manual media
1289 ==============================
1292 - Audit M_ error codes to ensure they are correct and consistent.
1293 - Add variable break characters to lex analyzer.
1294 Either a bit mask or a string of chars so that
1295 the caller can change the break characters.
1296 - Make a single T_BREAK to replace T_COMMA, etc.
1297 - Ensure that File daemon and Storage daemon can
1298 continue a save if the Director goes down (this
1299 is NOT currently the case). Must detect socket error,
1300 buffer messages for later.
1301 - Add ability to backup to two Storage devices (two SD sessions) at
1302 the same time -- e.g. onsite, offsite.

1307 Handling removable disks
1309 From: Karl Cunningham <karlc@keckec.com>
1311 My backups are only to hard disk these days, in removable bays. This is my
1312 idea of how a backup to hard disk would work more smoothly. Some of these
1313 things Bacula does already, but I mention them for completeness. If others
1314 have better ways to do this, I'd like to hear about it.
1316 1. Accommodate several disks, rotated similar to how tapes are. Identified
1317 by partition volume ID or perhaps by the name of a subdirectory.
1318 2. Abort & notify the admin if the wrong disk is in the bay.
1319 3. Write backups to different subdirectories for each machine to be backed
1321 4. Volumes (files) get created as needed in the proper subdirectory, one
1323 5. When a disk is recycled, remove or zero all old backup files. This is
1324 important as the disk being recycled may be close to full. This may be
1325 better done manually since the backup files for many machines may be
1326 scattered in many subdirectories.
1334 It is somewhat like a Full save becomes an incremental since
1335 the Base job (or jobs) plus other non-base files.
1337 - A Base backup is same as Full backup, just different type.
1338 - New BaseFiles table that contains:
1340 BaseJobId - Base JobId referenced for this FileId (needed ???)
1341 JobId - JobId currently running
1342 FileId - File not backed up, exists in Base Job
1343 FileIndex - FileIndex from Base Job.
1344 i.e. for each base file that exists but is not saved because
1345 it has not changed, the File daemon sends the JobId, BaseId,
1346 FileId, FileIndex back to the Director who creates the DB entry.
1347 - To initiate a Base save, the Director sends the FD
1348 the FileId, and full filename for each file in the Base.
1349 - When the FD finds a Base file, he requests the Director to
1350 send him the full File entry (stat packet plus MD5), or
1351 conversely, the FD sends it to the Director and the Director
1352 says yes or no. This can be quite rapid if the FileId is kept
1353 by the FD for each Base Filename.
1354 - It is probably better to have the comparison done by the FD
1355 despite the fact that the File entry must be sent across the
1357 - An alternative would be to send the FD the whole File entry
1358 from the start. The disadvantage is that it requires a lot of
1359 space. The advantage is that it requires less communications
1361 - The Job record must be updated to indicate that one or more
1363 - At end of Job, FD returns:
1364 1. Count of base files/bytes not written to tape (i.e. matches)
1365 2. Count of base file that were saved i.e. had changed.
1366 - No tape record would be written for a Base file that matches, in the
1367 same way that no tape record is written for Incremental jobs where
1368 the file is not saved because it is unchanged.
1369 - On a restore, all the Base file records must explicitly be
1370 found from the BaseFile tape. I.e. for each Full save that is marked
1371 to have one or more Base Jobs, search the BaseFile for all occurrences
1373 - An optimization might be to make the BaseFile have:
1379 This would avoid the need to explicitly fetch each File record for
1380 the Base job. The Base Job record will be fetched to get the
1381 VolSessionId and VolSessionTime.
1382 - Fix bpipe.c so that it does not modify results pointer.
1383 ***FIXME*** calling sequence should be changed.
1384 - Fix restore of acls and extended attributes to count ERROR
1385 messages and make errors non-fatal.
1386 - Put save/restore various platform acl/xattrs on a pointer to simplify
1388 - Add blast attributes to DIR to SD.
1389 - Implement unmount of USB volumes.
1390 - Look into using Dart for testing
