6 - !!! Cannot restore two jobs a the same time that were
7 written simultaneously unless they were totally spooled.
8 - Document cleaning up the spool files:
9 db, pid, state, bsr, mail, conmsg, spool
10 - Document the multiple-drive-changer.txt script.
11 - Pruning with Admin job.
12 - Does WildFile match against full name? Doc.
13 - %d and %v only valid on Director, not for ClientRunBefore/After.
14 - During tests with the 260 char fix code, I found one problem:
15 if the system "sees" a long path once, it seems to forget it's
16 working drive (e.g. c:\), which will lead to a problem during
17 the next job (create bootstrap file will fail). Here is the
18 workaround: specify absolute working and pid directory in
19 bacula-fd.conf (e.g. c:\bacula\working instead of
21 - Document techniques for restoring large numbers of files.
22 - Document setting my.cnf to big file usage.
23 - Add example of proper index output to doc. show index from File;
24 - Correct the Include syntax in the m4.xxx files in examples/conf
25 - Document JobStatus and Termination codes.
26 - Fix the error with the "DVI file can't be opened" while
27 building the French PDF.
28 - Document more DVD stuff
36 - Document all the little details of setting up certificates for
37 the Bacula data encryption code.
38 - Document more precisely how to use master keys -- especially
39 for disaster recovery.
42 - Migration from other vendors
46 - Backup conf/exe (all daemons)
47 - Backup up system state
48 - Detect state change of system (verify)
49 - Synthetic Full, Diff, Inc (Virtual, Reconstructed)

61 Extract capability (#25)
62 Continued enhancement of bweb
63 Threshold triggered migration jobs (not currently in list, but will be
65 Client triggered backups
66 Complete rework of the scheduling system (not in list)
67 Performance and usage instrumentation (not in list)
68 See email of 21Aug2007 for details.
69 - Look at: http://tech.groups.yahoo.com/group/cfg2html
70 and http://www.openeyet.nl/scc/ for managing customer changes
74 - Can be posible modify package to create and use configuration files in
79 /etc/bacula/bacula-dir.conf
80 /etc/bacula/conf.d/pools.conf
81 /etc/bacula/conf.d/clients.conf
82 /etc/bacula/conf.d/storages.conf
84 and into bacula-dir.conf file include
86 @/etc/bacula/conf.d/pools.conf
87 @/etc/bacula/conf.d/clients.conf
88 @/etc/bacula/conf.d/storages.conf
89 - Possibly add an Inconsistent state when a Volume is in error
91 - Fix #ifdefing so that smartalloc can be disabled. Check manual
92 -- the default is enabled.
93 - Change calling sequence to delete_job_id_range() in ua_cmds.c
94 the preceding strtok() is done inside the subroutine only once.
95 - Dangling softlinks are not restored properly. For example, take a
96 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
97 move the directory to another machine where the file /usr/share/autoconf does
98 not exist, back it up, then try a full restore. It fails.
99 - Softlinks that point to non-existent file are not restored in restore all,
100 but are restored if the file is individually selected. BUG!
101 - New directive "Delete purged Volumes"
103 - Prune by Job Level (Full, Differential, Incremental)
104 - Strict automatic pruning
105 - Implement unmount of USB volumes.
106 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
107 Win32 to avoid patent problems.
108 - Implement multiple jobid specification for the cancel command,
109 similar to what is permitted on the update slots command.
110 - Implement Bacula plugins -- design API
111 - modify pruning to keep a fixed number of versions of a file,
113 - the cd-command should allow complete paths
114 i.e. cd /foo/bar/foo/bar
115 -> if a customer mails me the path to a certain file,
116 its faster to enter the specified directory
117 - Make tree walk routines like cd, ls, ... more user friendly
118 by handling spaces better.
122 MA = (last_MA * 3 + rate) / 4
123 rate = (bytes - last_bytes) / (runtime - last_runtime)
124 - Add a recursive mark command (rmark) to restore.
125 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
126 of the same level and does not permit multiple simultaneous
127 running of that Job (i.e. lets any previous invocation finish
128 before doing Interval testing).
129 - Look at simplifying File exclusions.
131 - Auto update of slot:
132 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
133 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

137 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
138 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
139 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.

141 - Separate Files and Directories in catalog
142 - Create FileVersions table
143 - Look at rsysnc for incremental updates and dedupping
144 - Add MD5 or SHA1 check in SD for data validation
145 - finish implementation of fdcalled -- see ua_run.c:105
146 - Fix problem in postgresql.c in my_postgresql_query, where the
147 generation of the error message doesn't differentiate result==NULL
148 and a bad status from that result. Not only that, the result is
149 cleared on a bail_out without having generated the error message.
151 - Implement SDErrors (must return from SD)
152 - Implement USB keyboard support in rescue CD.
153 - Implement continue spooling while despooling.
154 - Remove all install temp files in Win32 PLUGINSDIR.
155 - Audit retention periods to make sure everything is 64 bit.
156 - No where in restore causes kaboom.
157 - Performance: multiple spool files for a single job.
158 - Performance: despool attributes when despooling data (problem
159 multiplexing Dir connection).
160 - Make restore use the in-use volume reservation algorithm.
161 - When Pool specifies Storage command override does not work.
162 - Implement wait_for_sysop() message display in wait_for_device(), which
163 now prints warnings too often.
164 - Ensure that each device in an Autochanger has a different
166 - Look at sg_logs -a /dev/sg0 for getting soft errors.
167 - btape "test" command with Offline on Unmount = yes
169 This test is essential to Bacula.
171 I'm going to write one record in file 0,
172 two records in file 1,
173 and three records in file 2
175 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715

178 Kaboom! btape, btape got signal 11. Attempting traceback.
180 - Encryption -- email from Landon
181 > The backup encryption algorithm is currently not configurable, and is
182 > set to AES_128_CBC in src/filed/backup.c. The encryption code
183 > supports a number of different ciphers (as well as adding arbitrary
184 > new ones) -- only a small bit of code would be required to map a
185 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is
186 > interested in implementing this functionality.
188 - Figure out some way to "automatically" backup conf changes.
189 - Add the OS version back to the Win32 client info.
190 - Restarted jobs have a NULL in the from field.
191 - Modify SD status command to indicate when the SD is writing
192 to a DVD (the device is not open -- see bug #732).
193 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
194 and possibly changing the blobs into varchar.
195 - Ensure that the SD re-reads the Media record if the JobFiles
196 does not match -- it may have been updated by another job.
198 - Test Volume compatibility between machine architectures
199 - Encryption documentation
200 - Wrong jobbytes with query 12 (todo)
201 - Bare-metal recovery Windows (todo)
206 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
208 - Maximum number of scratch volumes
210 - Next Pool (already have)
211 - Reclamation threshold
213 - Reuse delay (after all files purged from volume before it can be used)
214 - Copy Pool = xx, yyy (or multiple lines).
216 - Allow pool selection during restore.
218 - Average tape size from Eric
219 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
220 count(Media.MediaId) AS volnum,
221 sum(Media.VolBytes) AS voltotal,
222 Media.PoolId AS PoolId,
223 Media.MediaType AS MediaType
225 LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,
226 Media.MediaType AS MediaType

229 GROUP BY Media.MediaType
230 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
231 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
235 - Add doc for bweb -- especially Installation
237 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
239 - Despool attributes in separate thread
242 - Check why restore repeatedly sends Rechdrs between
243 each data chunk -- according to James Harper 9Jan07.
246 - More intelligent re-run
248 - Incremental backup -- rsync, Stow
251 - Try to fix bscan not working with multiple DVD volumes bug #912.
252 - Look at mondo/mindi
253 - Make Bacula by default not backup tmpfs, procfs, sysfs, ...
254 - Fix hardlinked immutable files when linking a second file, the
255 immutable flag must be removed prior to trying to link it.
256 - Change dbcheck to tell users to use native tools for fixing
257 broken databases, and to ensure they have the proper indexes.
258 - add udev rules for Bacula devices.
259 - If a job terminates, the DIR connection can close before the
260 Volume info is updated, leaving the File count wrong.
261 - Look at why SIGPIPE during connection can cause seg fault in
262 writing the daemon message, when Dir dropped to bacula:bacula
263 - Look at zlib 32 => 64 problems.
264 - Possibly turn on St. Bernard code.
265 - Fix bextract to restore ACLs, or better yet, use common routines.
266 - Do we migrate appendable Volumes?
267 - Remove queue.c code.
268 - Print warning message if LANG environment variable does not specify
270 - New dot commands from Arno.
271 .show device=xxx lists information from one storage device, including
272 devices (I'm not even sure that information exists in the DIR...)
273 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
274 better machine-readable output like "Ok" or "Error busy"
275 .move eject device=xxx toslot=yyy the same as above, but with a new
276 target slot. The catalog should be updated accordingly.
277 .move transfer device=xxx fromslot=yyy toslot=zzz

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

601 askdir.c:219 NULL Volume name. This shouldn't happen!!!
602 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
603 Label command failed for Volume DLT-20Dec04.
604 Do not forget to mount the drive!!!
605 - Bug: if a job is manually scheduled to run later, it does not appear
606 in any status report and cannot be cancelled.
611 How about introducing a Type = MgmtPolicy job type? That job type would
612 be responsible for scanning the Bacula environment looking for specific
613 conditions, and submitting the appropriate jobs for implementing said
617 Name = "Migration-Policy"
619 Policy Selection Job Type = Migrate
620 Scope = "<keyword> <operator> <regexp>"
621 Threshold = "<keyword> <operator> <regexp>"
622 Job Template = <template-name>
625 Where <keyword> is any legal job keyword, <operator> is a comparison
626 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
627 appropriate regexp. I could see an argument for Scope and Threshold
628 being SQL queries if we want to support full flexibility. The
629 Migration-Policy job would then get scheduled as frequently as a site
630 felt necessary (suggested default: every 15 minutes).
635 Name = "Migration-Policy"
637 Policy Selection Job Type = Migration
639 Threshold = "Migration Selection Type = LowestUtil"
640 Job Template = "MigrationTemplate"
643 would select all pools for examination and generate a job based on
644 MigrationTemplate to automatically select the volume with the lowest
645 usage and migrate it's contents to the nextpool defined for that pool.
647 This policy abstraction would be really handy for adjusting the behavior
648 of Bacula according to site-selectable criteria (one thing that pops
649 into mind is Amanda's ability to automatically adjust backup levels
650 depending on various criteria).
656 - Add Pool/Storage override regression test.
657 - Add delete JobId to regression.
658 - Add a regression test for dbcheck.
659 - New test to add bscan to four-concurrent-jobs regression,
660 i.e. after the four-concurrent jobs zap the
661 database as is done in the bscan-test, then use bscan to
662 restore the database, do a restore and compare with the
664 - Add restore of specific JobId to regression (item 3
665 on the restore prompt)
666 - Add IPv6 to regression
667 - Add database test to regression. Test each function like delete,
670 - AntiVir can slow down backups on Win32 systems.
671 - Win32 systems with FAT32 can be much slower than NTFS for
672 more than 1000 files per directory.
676 - A HOLD command to stop all jobs from starting.
677 - A PAUSE command to pause all running jobs ==> release the
679 - Media Type = LTO,LTO-2,LTO-3
680 Media Type Read = LTO,LTO2,LTO3
681 Media Type Write = LTO2, LTO3
683 === From Carsten Menke <bootsy52@gmx.net>
685 Following is a list of what I think in the situations where I'm faced with,
686 could be a usefull enhancement to bacula, which I'm certain other users will
687 benefit from as well.
689 1. NextJob/NextJobs Directive within a Job Resource in the form of
690 NextJobs = job1,job2.
693 I currently solved the problem with running multiple jobs each after each
694 by setting the Max Wait Time for a job to 8 hours, and give
695 the jobs different Priorities. However, there scenarios where
696 1 Job is directly depending on another job, so if the former job fails,
697 the job after it needn't to be run
698 while maybe other jobs should run despite of that
701 A Backup Job and a Verify job, if the backup job fails there is no need to run
702 the verify job, as the backup job already failed. However, one may like
703 to backup the Catalog to disk despite of that the main backup job failed.
706 I see that this is related to the Event Handlers which are on the ToDo
707 list, also it is maybe a good idea to check for the return value and
708 execute different actions based on the return value
711 3. offline capability to bconsole
714 Currently I use a script which I execute within the last Job via the
715 RunAfterJob Directive, to release and eject the tape.
716 So I have to call bconsole "release=Storage-Name" and afterwards
717 mt -f /dev/nst0 eject to get the tape out.
719 If I have multiple Storage Devices, than these may not be /dev/nst0 and
720 I have to modify the script or call it with parameters etc.
721 This would actually not be needed, as everything is already defined
722 in bacula-sd.conf and if I can invoke bconsole with the
723 storage name via $1 in the script than I'm done and information is
726 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
730 For the reason mentioned in 3. to have the ability to call a
731 script with /scripts/foobar %s and in the script use $1
732 to pass the Storage Name to bconsole
734 5. Setting Volume State within a Job Resource
737 Instead of using "Maximum Volume Jobs" in the Pool Resource,
738 I would have the possibilty to define
739 in a Job Resource that after this certain job is run, the Volume State
740 should be set to "Volume State = Used", this give more flexibility (IMHO).
742 6. Localization of Bacula Messages
745 Unfortunatley many,many people I work with don't speak english very well.
746 So if at least the Reporting messages would be localized then they
747 would understand that they have to change the tape,etc. etc.
749 I volunteer to do the german translations, and if I can convince my wife also
750 french and Morre (western african language).
752 7. OK, this is evil, probably bound to security risks and maybe not possible
753 due to the design of bacula.
755 Implementation of Backtics ( `command` ) for shell comand execution to
756 the "Label Format" Directive.
760 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
761 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
762 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
763 the localized name for the day of the week appended to the
764 format string. Then I have the tape labeled automatically with weekday
765 name in the correct language.
767 - Make output from status use html table tags for nicely
768 presenting in a browser.
769 - Browse generations of files.
770 - I've seen an error when my catalog's File table fills up. I
771 then have to recreate the File table with a larger maximum row
772 size. Relevant information is at
773 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
774 "Installing and Configuring MySQL" chapter should talk a bit
775 about this potential problem, and recommend a solution.
776 - For Solaris must use POSIX awk.
777 - Want speed of writing to tape while despooling.
778 - Supported autochanger:
786 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
787 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
788 - Add regex from http://www.pcre.org to Bacula for Win32.
789 - Use only shell tools no make in CDROM package.
790 - Include within include does it work?
791 - Implement a Pool of type Cleaning?
792 - Implement VolReadTime and VolWriteTime in SD
793 - Modify Backing up Your Database to include a bootstrap file.
794 - Think about making certain database errors fatal.
795 - Look at correcting the time jump in the scheduler for daylight
796 savings time changes.
797 - Add a "real" timer to network connections.
798 - Promote to Full = Time period
799 - Check dates entered by user for correctness (month/day/... ranges)
800 - Compress restore Volume listing by date and first file.
801 - Look at patches/bacula_db.b2z postgresql that loops during restore.
803 - Perhaps add read/write programs and/or plugins to FileSets.
804 - How to handle backing up portables ...
805 - Add some sort of guaranteed Interval for upgrading jobs.
806 - Can we write the state file after every job terminates? On Win32
807 the system crashes and the state file is not updated.
810 Documentation to do: (any release a little bit at a time)
811 - Doc to do unmount before removing magazine.
812 - Alternative to static linking "ldd prog" save all binaries listed,
813 restore them and point LD_LIBRARY_PATH to them.
814 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
815 - Document query file format.
816 - Add more documentation for bsr files.
817 - Document problems with Verify and pruning.
818 - Document how to use multiple databases.
819 - VXA drives have a "cleaning required"
820 indicator, but Exabyte recommends preventive cleaning after every 75
823 In this context, it should be noted that Exabyte has a command-line
824 vxatool utility available for free download. (The current version is
825 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
826 test the drive, unload tapes, change drive settings, flash new firmware,
828 Of particular interest in this context is that vxatool <device> -i will
829 report, among other details, the time since last cleaning in tape motion
830 minutes. This information can be retrieved (and settings changed, for
831 that matter) through the generic-SCSI device even when Bacula has the
832 regular tape device locked. (Needless to say, I don't recommend
833 changing tape settings while a job is running.)
834 - Lookup HP cleaning recommendations.
835 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
836 - Document doing table repair
839 ===================================
840 - Add macro expansions in JobDefs.
841 Run Before Job = "SomeFile %{Level} %{Client}"
842 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
843 - Use non-blocking network I/O but if no data is available, use
845 - Use gather write() for network I/O.
846 - Autorestart on crash.
847 - Add bandwidth limiting.
848 - When an error in input occurs and conio beeps, you can back
849 up through the prompt.
850 - Detect fixed tape block mode during positioning by looking at
851 block numbers in btape "test". Possibly adjust in Bacula.
852 - Fix list volumes to output volume retention in some other
853 units, perhaps via a directive.
854 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
855 with multiple priorities.
856 - If you use restore replace=never, the directory attributes for
857 non-existent directories will not be restored properly.
859 - see lzma401.zip in others directory for new compression
861 - Allow the user to select JobType for manual pruning/purging.
862 - bscan does not put first of two volumes back with all info in
864 - Figure out how to make named console messages go only to that
865 console and to the non-restricted console (new console class?).
866 - Make restricted console prompt for password if *ask* is set or
867 perhaps if password is undefined.
868 - Implement "from ISO-date/time every x hours/days/weeks/months" in
871 ==== from Marc Schoechlin
872 - the help-command should be more verbose
873 (it should explain the paramters of the different
875 -> its time-comsuming to consult the manual anytime
876 you need a special parameter
877 -> maybe its more easy to maintain this, if the
878 descriptions of that commands are outsourced to
880 - if the password is not configured in bconsole.conf
881 you should be asked for it.
882 -> sometimes you like to do restore on a customer-machine
883 which shouldnt know the password for bacula.
884 -> adding the password to the file favours admins
885 to forget to remove the password after usage
887 the protection of that file is less important
888 - long-listed-output of commands should be scrollable
889 like the unix more/less-command does
890 -> if someone runs 200 and more machines, the lists could
891 be a little long and complex
892 - command-output should be shown column by column
893 to reduce scrolling and to increase clarity
895 - lsmark should list the selected files with full
897 - wildcards for selecting and file and directories would be nice
898 - any actions should be interuptable with STRG+C
899 - command-expansion would be pretty cool
901 - When the replace Never option is set, new directory permissions
902 are not restored. See bug 213. To fix this requires creating a
903 list of newly restored directories so that those directory
904 permissions *can* be restored.
905 - Add prune all command
906 - Document fact that purge can destroy a part of a restore by purging
907 one volume while others remain valid -- perhaps mark Jobs.
908 - Add multiple-media-types.txt
909 - look at mxt-changer.html
910 - Make ? do a help command (no return needed).
911 - Implement restore directory.
912 - Document streams and how to implement them.
913 - Try not to re-backup a file if a new hard link is added.
914 - Add feature to backup hard links only, but not the data.
915 - Fix stream handling to be simpler.
916 - Add Priority and Bootstrap to Run a Job.
917 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
919 - Remove View FileSet button from Run a Job dialog.
920 - Handle prompt for restore job at end of Restore command.
921 - Add display of total selected files to Restore window.
922 - Add tree pane to left of window.
923 - Add progress meter.
924 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
925 - Add message to user to check for fixed block size when the forward
926 space test fails in btape.
927 - When unmarking a directory check if all files below are unmarked and
928 then remove the + flag -- in the restore tree.
929 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
930 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
931 - Revisit the question of multiple Volumes (disk) on a single device.
932 - Add a block copy option to bcopy.
933 - Fix "llist jobid=xx" where no fileset or client exists.
934 - For each job type (Admin, Restore, ...) require only the really necessary
935 fields.- Pass Director resource name as an option to the Console.
936 - Add a "batch" mode to the Console (no unsolicited queries, ...).
937 - Allow browsing the catalog to see all versions of a file (with
938 stat data on each file).
939 - Restore attributes of directory if replace=never set but directory
941 - Use SHA1 on authentication if possible.
942 - See comtest-xxx.zip for Windows code to talk to USB.
943 - Add John's appended files:
944 Appended = { /files/server/logs/http/*log }
945 and such files would be treated as follows.On a FULL backup, they would
946 be backed up like any other file.On an INCREMENTAL backup, where a
947 previous INCREMENTAL or FULL was already in thecatalogue and the length
948 of the file wasgreater than the length of the last backup, only thedata
949 added since the last backup will be dumped.On an INCREMENTAL backup, if
950 the length of the file is less than thelength of the file with the same
951 name last backed up, the completefile is dumped.On Windows systems, with
952 creation date of files, we can be evensmarter about this and not count
953 entirely upon the length.On a restore, the full and all incrementals
954 since it will beapplied in sequence to restore the file.
955 - Check new HAVE_WIN32 open bits.
956 - Check if the tape has moved before writing.
957 - Handling removable disks -- see below:
958 - Add FromClient and ToClient keywords on restore command (or
959 BackupClient RestoreClient).
960 - Implement a JobSet, which groups any number of jobs. If the
961 JobSet is started, all the jobs are started together.
962 Allow Pool, Level, and Schedule overrides.
963 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
964 correctly for multiple simultaneous jobs.
965 - Implement the Media record flag that indicates that the Volume does disk
967 - Implement VolAddr, which is used when Volume is addressed like a disk,
968 and form it from VolFile and VolBlock.
969 - Fix fast block rejection (stored/read_record.c:118). It passes a null
970 pointer (rec) to try_repositioning().
971 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
972 which would take precidence over the Catalog "JobRetention".
973 - Implement Label Format in Add and Label console commands.
974 - Put email tape request delays on one or more variables. User wants
975 to cancel the job after a certain time interval. Maximum Mount Wait?
976 - Job, Client, Device, Pool, or Volume?
977 Is it possible to make this a directive which is *optional* in multiple
978 resources, like Level? If so, I think I'd make it an optional directive
979 in Job, Client, and Pool, with precedence such that Job overrides Client
980 which in turn overrides Pool.
982 - New Storage specifications:
983 - Want to write to multiple storage devices simultaneously
984 - Want to write to multiple storage devices sequentially (in one job)
985 - Want to read/write simultaneously
986 - Key is MediaType -- it must match
988 Passed to SD as a sort of BSR record called Storage Specification
992 MediaType -> Next MediaType
994 Device -> Next Device
996 Allow multiple Storage specifications
1004 Allow Multiple Pool specifications (note, Pool currently
1006 Allow Multiple MediaType specifications in Dir conf
1007 Allow Multiple Device specifications in Dir conf
1008 Perhaps keep this in a single SSR
1009 Tie a Volume to a specific device by using a MediaType that
1010 is contained in only one device.
1011 In SD allow Device to have Multiple MediaTypes
1013 - Ideas from Jerry Scharf:
1014 First let's point out some big pluses that bacula has for this
1016 more importantly it's active. Thank you so much for that
1017 even more important, it's not flaky
1018 it has an open access catalog, opening many possibilities
1019 it's pushing toward heterogeneous systems capability
1021 Macintosh file client
1022 macs are an interesting niche, but I fear a server is a rathole
1023 working bare iron recovery for windows
1024 the option for inc/diff backups not reset on fileset revision
1025 a) use both change and inode update time against base time
1026 b) do the full catalog check (expensive but accurate)
1027 sizing guide (how much system is needed to back up N systems/files)
1028 consultants on using bacula in building a disaster recovery system
1029 an integration guide
1030 or how to get at fancy things that one could do with bacula
1031 logwatch code for bacula logs (or similar)
1032 linux distro inclusion of bacula (brings good and bad, but necessary)
1033 win2k/XP server capability (icky but you asked)
1034 support for Oracle database ??
1036 - Look at adding SQL server and Exchange support for Windows.
1037 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1038 is needed to properly specify ranges.
1039 - Add progress of files/bytes to SD and FD.
1040 - Print warning message if FileId > 4 billion
1041 - do a "messages" before the first prompt in Console
1042 - Client does not show busy during Estimate command.
1043 - Implement Console mtx commands.
1044 - Implement a Mount Command and an Unmount Command where
1045 the users could specify a system command to be performed
1046 to do the mount, after which Bacula could attempt to
1047 read the device. This is for Removeable media such as a CDROM.
1048 - Most likely, this mount command would be invoked explicitly
1049 by the user using the current Console "mount" and "unmount"
1050 commands -- the Storage Daemon would do the right thing
1051 depending on the exact nature of the device.
1052 - As with tape drives, when Bacula wanted a new removable
1053 disk mounted, it would unmount the old one, and send a message
1054 to the user, who would then use "mount" as described above
1055 once he had actually inserted the disk.
1056 - Implement dump/print label to UA
1057 - Spool to disk only when the tape is full, then when a tape is hung move
1059 - bextract is sending everything to the log file ****FIXME****
1060 - Allow multiple Storage specifications (or multiple names on
1061 a single Storage specification) in the Job record. Thus a job
1062 can be backed up to a number of storage devices.
1063 - Implement some way for the File daemon to contact the Director
1064 to start a job or pass its DHCP obtained IP number.
1065 - Implement a query tape prompt/replace feature for a console
1066 - Make sure that Bacula rechecks the tape after the 20 min wait.
1067 - Set IO_NOWAIT on Bacula TCP/IP packets.
1068 - Try doing a raw partition backup and restore by mounting a
1070 - From Lars Kellers:
1071 Yes, it would allow to highly automatic the request for new tapes. If a
1072 tape is empty, bacula reads the barcodes (native or simulated), and if
1073 an unused tape is found, it runs the label command with all the
1074 necessary parameters.
1076 By the way can bacula automatically "move" an empty/purged volume say
1077 in the "short" pool to the "long" pool if this pool runs out of volume
1079 - What to do about "list files job=xxx".
1080 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1081 file descriptor leak in Bacula.
1082 - Can we dynamically change FileSets?
1083 - If pool specified to label command and Label Format is specified,
1084 automatically generate the Volume name.
1085 - Add ExhautiveRestoreSearch
1086 - Look at the possibility of loading only the necessary
1087 data into the restore tree (i.e. do it one directory at a
1088 time as the user walks through the tree).
1089 - Possibly use the hash code if the user selects all for a restore command.
1090 - Fix "restore all" to bypass building the tree.
1091 - Prohibit backing up archive device (findlib/find_one.c:128)
1092 - Implement Release Device in the Job resource to unmount a drive.
1093 - Implement Acquire Device in the Job resource to mount a drive,
1094 be sure this works with admin jobs so that the user can get
1095 prompted to insert the correct tape. Possibly some way to say to
1096 run the job but don't save the files.
1097 - Make things like list where a file is saved case independent for
1099 - Implement a Recycle command
1100 - Start working on Base jobs.
1101 - From Phil Stracchino:
1102 It would probably be a per-client option, and would be called
1103 something like, say, "Automatically purge obsoleted jobs". What it
1104 would do is, when you successfully complete a Differential backup of a
1105 client, it would automatically purge all Incremental backups for that
1106 client that are rendered redundant by that Differential. Likewise,
1107 when a Full backup on a client completed, it would automatically purge
1108 all Differential and Incremental jobs obsoleted by that Full backup.
1109 This would let people minimize the number of tapes they're keeping on
1110 hand without having to master the art of retention times.
1111 - When doing a Backup send all attributes back to the Director, who
1112 would then figure out what files have been deleted.
1113 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1114 explicit permission to do so. It should also mark the tape in error
1115 if there is an error.
1116 - Cancel waiting for Client connect in SD if FD goes away.
1118 - Implement timeout in response() when it should come quickly.
1119 - Implement a Slot priority (loaded/not loaded).
1120 - Implement "vacation" Incremental only saves.
1121 - Implement create "FileSet"?
1122 - Add prefixlinks to where or not where absolute links to FD.
1123 - Issue message to mount a new tape before the rewind.
1124 - Simplified client job initiation for portables.
1125 - If SD cannot open a drive, make it periodically retry.
1126 - Add more of the config info to the tape label.
1128 - Refine SD waiting output:
1129 Device is being positioned
1130 > Device is being positioned for append
1131 > Device is being positioned to file x
1133 - Figure out some way to estimate output size and to avoid splitting
1134 a backup across two Volumes -- this could be useful for writing CDROMs
1135 where you really prefer not to have it split -- not serious.
1136 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1137 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1138 actual data on the Volume and compare it.

1149 - Need a verbose mode in restore, perhaps to bsr.
1150 - bscan without -v is too quiet -- perhaps show jobs.
1151 - Add code to reject whole blocks if not wanted on restore.
1152 - Check if we can increase Bacula FD priorty in Win2000
1153 - Check if both CatalogFiles and UseCatalog are set to SD.
1154 - Possibly add email to Watchdog if drive is unmounted too
1155 long and a job is waiting on the drive.
1156 - After unmount, if restore job started, ask to mount.

1202 - Autolabel should be specified by DIR instead of SD.
1204 - Add media capacity
1205 - AutoScan (check checksum of tape)
1206 - Format command = "format /dev/nst0"
1210 - Seek resolution (usually corresponds to buffer size)
1211 - EODErrorCode=ENOSPC or code

1234 times out jobs by asking the deamons where they are.
1235 - Enhance Jmsg code to permit buffering and saving to disk.
1236 - Verify from Volume
1237 - Need report class for messages. Perhaps
1238 report resource where report=group of messages
1239 - enhance scan_attrib and rename scan_jobtype, and
1240 fill in code for "since" option
1241 - Director needs a time after which the report status is sent
1242 anyway -- or better yet, a retry time for the job.
1243 - Don't reschedule a job if previous incarnation is still running.
1244 - Some way to automatically backup everything is needed????
1245 - Need a structure for pending actions:
1247 - termination status (part of buffered msgs?)
1249 Read, Write, Clean, Delete
1250 - Login to Bacula; Bacula users with different permissions:
1251 owner, group, user, quotas
1252 - Store info on each file system type (probably in the job header on tape.
1253 This could be the output of df; or perhaps some sort of /etc/mtab record.

1256 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1257 To: <kern@sibbald.com>
1258 Subject: RE: [Bacula-users] future large programming jobs
1259 Date: Thu, 26 Feb 2004 11:34:54 -0600
1261 I noticed the subject thread and thought I would offer the following
1262 merely as sources of ideas, i.e. something to think about, not even as
1263 strong as a request. In my former life (before retiring) I often
1264 dealt with backups and storage management issues/products as a
1265 developer and as a consultant. I am currently migrating my personal
1266 network from amanda to bacula specifically because of the ability to
1267 cross media boundaries during storing backups.
1268 Are you familiar with the commercial product called ADSM (I think IBM
1269 now sells it under the Tivoli label)? It has a couple of interesting
1270 ideas that may apply to the following topics.
1272 1. Migration: Consider that when you need to restore a system, there
1273 may be pressure to hurry. If all the information for a single client
1274 can eventually end up on the same media (and in chronological order),
1275 the restore is facillitated by not having to search past information
1276 from other clients. ADSM has the concept of "client affinity" that
1277 may be associated with it's storage pools. It seems to me that this
1278 concept (as an optional feature) might fit in your architecture for
1281 ADSM also has the concept of defining one or more storage pools as
1282 "copy pools" (almost mirrors, but only in the sense of contents).
1283 These pools provide the ability to have duplicte data stored both
1284 onsite and offsite. The copy process can be scheduled to be handled
1285 by their storage manager during periods when there is no backup
1286 activity. Again, the migration process might be a place to consider
1287 implementing something like this.
1290 > It strikes me that it would be very nice to be able to do things

1300 This is the goal. In the first step (before events), you simply
1302 the Migration to tape later.
1304 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1305 the database. Once a file (unique by path and metadata such as dates,
1306 size, ownership, etc.) is in a copy pool, no more copies are made. In
1307 other words, when you start ADSM, it begins like your concept of a
1308 base job. After that it is in the "incremental" mode. You can
1309 configure the number of "generations" of files to be retained, plus a
1310 retention date after which even old generations are purged. The
1311 database tracks the contents of media and projects the percentage of
1312 each volume that is valid. When the valid content of a volume drops
1313 below a configured percentage, the valid data are migrated to another
1314 volume and the old volume is marked as empty. Note, this requires
1315 ADSM to have an idea of the contents of a client, i.e. marking the
1316 database when an existing file was deleted, but this would solve your
1317 issue of restoring a client without restoring deleted files.
1319 This is pretty far from what bacula now does, but if you are going to
1320 rip things up for Base jobs,.....
1321 Also, the benefits of this are huge for very large shops, especially
1322 with media robots, but are a pain for shops with manual media
1326 > Base jobs sound pretty useful, but I'm not dying for them.
1328 Nobody is dying for them, but when you see what it does, you will die
1334 ==============================
1337 - Implement FSM (File System Modules).
1338 - Audit M_ error codes to ensure they are correct and consistent.
1339 - Add variable break characters to lex analyzer.
1340 Either a bit mask or a string of chars so that
1341 the caller can change the break characters.
1342 - Make a single T_BREAK to replace T_COMMA, etc.
1343 - Ensure that File daemon and Storage daemon can
1344 continue a save if the Director goes down (this
1345 is NOT currently the case). Must detect socket error,
1346 buffer messages for later.
1347 - Add ability to backup to two Storage devices (two SD sessions) at
1348 the same time -- e.g. onsite, offsite.
1350 ======================================================
1352 It is somewhat like a Full save becomes an incremental since
1353 the Base job (or jobs) plus other non-base files.
1355 - A Base backup is same as Full backup, just different type.
1356 - New BaseFiles table that contains:
1358 BaseJobId - Base JobId referenced for this FileId (needed ???)
1359 JobId - JobId currently running
1360 FileId - File not backed up, exists in Base Job
1361 FileIndex - FileIndex from Base Job.
1362 i.e. for each base file that exists but is not saved because
1363 it has not changed, the File daemon sends the JobId, BaseId,
1364 FileId, FileIndex back to the Director who creates the DB entry.
1365 - To initiate a Base save, the Director sends the FD
1366 the FileId, and full filename for each file in the Base.
1367 - When the FD finds a Base file, he requests the Director to
1368 send him the full File entry (stat packet plus MD5), or
1369 conversely, the FD sends it to the Director and the Director
1370 says yes or no. This can be quite rapid if the FileId is kept
1371 by the FD for each Base Filename.
1372 - It is probably better to have the comparison done by the FD
1373 despite the fact that the File entry must be sent across the
1375 - An alternative would be to send the FD the whole File entry
1376 from the start. The disadvantage is that it requires a lot of
1377 space. The advantage is that it requires less communications
1379 - The Job record must be updated to indicate that one or more
1381 - At end of Job, FD returns:
1382 1. Count of base files/bytes not written to tape (i.e. matches)
1383 2. Count of base file that were saved i.e. had changed.
1384 - No tape record would be written for a Base file that matches, in the
1385 same way that no tape record is written for Incremental jobs where
1386 the file is not saved because it is unchanged.
1387 - On a restore, all the Base file records must explicitly be
1388 found from the BaseFile tape. I.e. for each Full save that is marked
1389 to have one or more Base Jobs, search the BaseFile for all occurrences
1391 - An optimization might be to make the BaseFile have:
1397 This would avoid the need to explicitly fetch each File record for
1398 the Base job. The Base Job record will be fetched to get the
1399 VolSessionId and VolSessionTime.

1403 Handling removable disks
1405 From: Karl Cunningham <karlc@keckec.com>
1407 My backups are only to hard disk these days, in removable bays. This is my
1408 idea of how a backup to hard disk would work more smoothly. Some of these
1409 things Bacula does already, but I mention them for completeness. If others
1410 have better ways to do this, I'd like to hear about it.
1412 1. Accommodate several disks, rotated similar to how tapes are. Identified
1413 by partition volume ID or perhaps by the name of a subdirectory.
1414 2. Abort & notify the admin if the wrong disk is in the bay.
1415 3. Write backups to different subdirectories for each machine to be backed
1417 4. Volumes (files) get created as needed in the proper subdirectory, one
1419 5. When a disk is recycled, remove or zero all old backup files. This is
1420 important as the disk being recycled may be close to full. This may be
1421 better done manually since the backup files for many machines may be
1422 scattered in many subdirectories.
1429 - Fix bpipe.c so that it does not modify results pointer.
1430 ***FIXME*** calling sequence should be changed.
