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

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 - Detect deadlocks in reservations.
76 - Add list during dump
77 - Add in plugin code flag
78 - Add bRC_EndJob -- stops more calls to plugin this job
79 - Add bRC_Term (unload plugin)
80 - remove time_t from Jmsg and use utime_t?
82 - Deadlock detection, watchdog sees if counter advances when jobs are
83 running. With debug on, can do a "status" command.
84 - User options for plugins.
85 - Pool Storage override precidence over command line.
86 - Autolabel only if Volume catalog information indicates tape not
87 written. This will avoid overwriting a tape that gets an I/O
88 error on reading the volume label.
89 - I/O error, SD thinks it is not the right Volume, should check slot
90 then disable volume, but Asks for mount.
91 - Can be posible modify package to create and use configuration files in
96 /etc/bacula/bacula-dir.conf
97 /etc/bacula/conf.d/pools.conf
98 /etc/bacula/conf.d/clients.conf
99 /etc/bacula/conf.d/storages.conf
101 and into bacula-dir.conf file include
103 @/etc/bacula/conf.d/pools.conf
104 @/etc/bacula/conf.d/clients.conf
105 @/etc/bacula/conf.d/storages.conf
106 - Possibly add an Inconsistent state when a Volume is in error
108 - Fix #ifdefing so that smartalloc can be disabled. Check manual
109 -- the default is enabled.
110 - Change calling sequence to delete_job_id_range() in ua_cmds.c
111 the preceding strtok() is done inside the subroutine only once.
112 - Dangling softlinks are not restored properly. For example, take a
113 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
114 move the directory to another machine where the file /usr/share/autoconf does
115 not exist, back it up, then try a full restore. It fails.
116 - Softlinks that point to non-existent file are not restored in restore all,
117 but are restored if the file is individually selected. BUG!
118 - New directive "Delete purged Volumes"
120 - Prune by Job Level (Full, Differential, Incremental)
121 - Strict automatic pruning
122 - Implement unmount of USB volumes.
123 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
124 Win32 to avoid patent problems.
125 - Implement multiple jobid specification for the cancel command,
126 similar to what is permitted on the update slots command.
127 - modify pruning to keep a fixed number of versions of a file,
129 - the cd-command should allow complete paths
130 i.e. cd /foo/bar/foo/bar
131 -> if a customer mails me the path to a certain file,
132 its faster to enter the specified directory
133 - Make tree walk routines like cd, ls, ... more user friendly
134 by handling spaces better.
138 MA = (last_MA * 3 + rate) / 4
139 rate = (bytes - last_bytes) / (runtime - last_runtime)
140 - Add a recursive mark command (rmark) to restore.
141 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
142 of the same level and does not permit multiple simultaneous
143 running of that Job (i.e. lets any previous invocation finish
144 before doing Interval testing).
145 - Look at simplifying File exclusions.
147 - Auto update of slot:
148 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
149 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

154 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
155 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.
156 02-Nov 12:58 rufus-dir JobId 10: Bacula rufus-dir 2.3.6 (26Oct07): 02-Nov-2007 12:58:51
157 - Separate Files and Directories in catalog
158 - Create FileVersions table
159 - Look at rsysnc for incremental updates and dedupping
160 - Add MD5 or SHA1 check in SD for data validation
161 - finish implementation of fdcalled -- see ua_run.c:105
162 - Fix problem in postgresql.c in my_postgresql_query, where the
163 generation of the error message doesn't differentiate result==NULL
164 and a bad status from that result. Not only that, the result is
165 cleared on a bail_out without having generated the error message.
167 - Implement SDErrors (must return from SD)
168 - Implement USB keyboard support in rescue CD.
169 - Implement continue spooling while despooling.
170 - Remove all install temp files in Win32 PLUGINSDIR.
171 - Audit retention periods to make sure everything is 64 bit.
172 - No where in restore causes kaboom.
173 - Performance: multiple spool files for a single job.
174 - Performance: despool attributes when despooling data (problem
175 multiplexing Dir connection).
176 - Make restore use the in-use volume reservation algorithm.
177 - When Pool specifies Storage command override does not work.
178 - Implement wait_for_sysop() message display in wait_for_device(), which
179 now prints warnings too often.
180 - Ensure that each device in an Autochanger has a different
182 - Look at sg_logs -a /dev/sg0 for getting soft errors.
183 - btape "test" command with Offline on Unmount = yes
185 This test is essential to Bacula.
187 I'm going to write one record in file 0,
188 two records in file 1,
189 and three records in file 2
191 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715
192 dev.c:714 Bad call to rewind. Device "LTO" (/dev/nst0) not open
193 02-Feb 11:00 btape: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation
194 Kaboom! btape, btape got signal 11. Attempting traceback.
196 - Encryption -- email from Landon
197 > The backup encryption algorithm is currently not configurable, and is
198 > set to AES_128_CBC in src/filed/backup.c. The encryption code
199 > supports a number of different ciphers (as well as adding arbitrary
200 > new ones) -- only a small bit of code would be required to map a
201 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is
202 > interested in implementing this functionality.
204 - Figure out some way to "automatically" backup conf changes.
205 - Add the OS version back to the Win32 client info.
206 - Restarted jobs have a NULL in the from field.
207 - Modify SD status command to indicate when the SD is writing
208 to a DVD (the device is not open -- see bug #732).
209 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
210 and possibly changing the blobs into varchar.
211 - Ensure that the SD re-reads the Media record if the JobFiles
212 does not match -- it may have been updated by another job.
214 - Test Volume compatibility between machine architectures
215 - Encryption documentation
216 - Wrong jobbytes with query 12 (todo)
217 - Bare-metal recovery Windows (todo)
222 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
224 - Maximum number of scratch volumes
226 - Next Pool (already have)
227 - Reclamation threshold
229 - Reuse delay (after all files purged from volume before it can be used)
230 - Copy Pool = xx, yyy (or multiple lines).
232 - Allow pool selection during restore.
234 - Average tape size from Eric
235 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
236 count(Media.MediaId) AS volnum,
237 sum(Media.VolBytes) AS voltotal,
238 Media.PoolId AS PoolId,
239 Media.MediaType AS MediaType
241 LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,
242 Media.MediaType AS MediaType

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

323 - Possibly allow SD to spool even if a tape is not mounted.
324 - Figure out how to configure query.sql. Suggestion to use m4:

473 If this is not a blank tape, try unmounting and remounting the Volume.
475 - http://www.dwheeler.com/essays/commercial-floss.html
476 - Add VolumeLock to prevent all but lock holder (SD) from updating
477 the Volume data (with the exception of VolumeState).
478 - The btape fill command does not seem to use the Autochanger
479 - Make Windows installer default to system disk drive.
480 - Look at using ioctl(FIOBMAP, ...) on Linux, and
481 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
482 Win32 for sparse files.
483 http://www.flexhex.com/docs/articles/sparse-files.phtml

485 - Directive: at <event> "command"
486 - Command: pycmd "command" generates "command" event. How to
487 attach to a specific job?
488 - Integrate Christopher's St. Bernard code.
489 - run_cmd() returns int should return JobId_t
490 - get_next_jobid_from_list() returns int should return JobId_t
491 - Document export LDFLAGS=-L/usr/lib64
492 - Don't attempt to restore from "Disabled" Volumes.
493 - Network error on Win32 should set Win32 error code.
494 - What happens when you rename a Disk Volume?
495 - Job retention period in a Pool (and hence Volume). The job would
497 - Look at -D_FORTIFY_SOURCE=2
498 - Add Win32 FileSet definition somewhere
499 - Look at fixing restore status stats in SD.
500 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
501 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
502 - Implement a mode that says when a hard read error is
503 encountered, read many times (as it currently does), and if the
504 block cannot be read, skip to the next block, and try again. If
505 that fails, skip to the next file and try again, ...
507 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
508 insert into LevelType (LevelType,LevelTypeLong) values
512 - Show files/second in client status output.
513 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
514 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
515 see if it become stable and I just have to supervise
517 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
518 PoolId, and when it is empty remove it.
520 - Allow Check Labels to be used with Bacula labels.
521 - "Resuming" a failed backup (lost line for example) by using the
522 failed backup as a sort of "base" job.
524 - Email to the user when the tape is about to need changing x
525 days before it needs changing.
526 - Command to show next tape that will be used for a job even
527 if the job is not scheduled.
528 - From: Arunav Mandal <amandal@trolltech.com>
529 1. When jobs are running and bacula for some reason crashes or if I do a
530 restart it remembers and jobs it was running before it crashed or restarted
531 as of now I loose all jobs if I restart it.
533 2. When spooling and in the midway if client is disconnected for instance a
534 laptop bacula completely discard the spool. It will be nice if it can write
535 that spool to tape so there will be some backups for that client if not all.
537 3. We have around 150 clients machines it will be nice to have a option to
538 upgrade all the client machines bacula version automatically.
540 4. Atleast one connection should be reserved for the bconsole so at heavy load
541 I should connect to the director via bconsole which at sometimes I can't
543 5. Another most important feature that is missing, say at 10am I manually
544 started backup of client abc and it was a full backup since client abc has
545 no backup history and at 10.30am bacula again automatically started backup of
546 client abc as that was in the schedule. So now we have 2 multiple Full
547 backups of the same client and if we again try to start a full backup of
548 client backup abc bacula won't complain. That should be fixed.
550 - For Windows disaster recovery see http://unattended.sf.net/
551 - regardless of the retention period, Bacula will not prune the
552 last Full, Diff, or Inc File data until a month after the
553 retention period for the last Full backup that was done.
554 - update volume=xxx --- add status=Full
555 - Remove old spool files on startup.
556 - Exclude SD spool/working directory.
557 - Refuse to prune last valid Full backup. Same goes for Catalog.
559 - Make a callback when Rerun failed levels is called.
560 - Give Python program access to Scheduled jobs.
561 - Add setting Volume State via Python.
562 - Python script to save with Python, not save, save with Bacula.
563 - Python script to do backup.
565 - Change the Priority, Client, Storage, JobStatus (error)
566 at the start of a job.
567 - Why is SpoolDirectory = /home/bacula/spool; not reported
568 as an error when writing a DVD?
569 - Make bootstrap file handle multiple MediaTypes (SD)
570 - Remove all old Device resource code in Dir and code to pass it
571 back in SD -- better, rework it to pass back device statistics.
572 - Check locking of resources -- be sure to lock devices where previously
573 resources were locked.
574 - The last part is left in the spool dir.
577 - In restore don't compare byte count on a raw device -- directory
578 entry does not contain bytes.
581 - Max Vols limit in Pool off by one?
582 - Implement Files/Bytes,... stats for restore job.
583 - Implement Total Bytes Written, ... for restore job.
584 - Despool attributes simultaneously with data in a separate
585 thread, rejoined at end of data spooling.
586 - 7. Implement new Console commands to allow offlining/reserving drives,
587 and possibly manipulating the autochanger (much asked for).
588 - Add start/end date editing in messages (%t %T, %e?) ...
589 - Add ClientDefs similar to JobDefs.
590 - Print more info when bextract -p accepts a bad block.
591 - Fix FD JobType to be set before RunBeforeJob in FD.
592 - Look at adding full Volume and Pool information to a Volume
593 label so that bscan can get *all* the info.
594 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
595 and there is only one volume in the pool, refuse to do it -- otherwise
596 he fills the Volume, then immediately starts reusing it.
597 - Implement copies and stripes.
598 - Add history file to console.
599 - Each file on tape creates a JobMedia record. Peter has 4 million
600 files spread over 10000 tape files and four tapes. A restore takes
601 16 hours to build the restore list.
602 - Add and option to check if the file size changed during backup.
603 - Make sure SD deletes spool files on error exit.
604 - Delete old spool files when SD starts.
605 - When labeling tapes, if you enter 000026, Bacula uses
606 the tape index rather than the Volume name 000026.
607 - Add offline tape command to Bacula console.
609 Enter MediaId or Volume name: 32
610 Enter new Volume name: DLT-20Dec04
611 Automatically selected Pool: Default
612 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...
613 Sending relabel command from "DLT-28Jun03" to "DLT-20Dec04" ...
614 block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
615 Error writing final EOF to tape. This tape may not be readable.
616 dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
617 askdir.c:219 NULL Volume name. This shouldn't happen!!!
618 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
619 Label command failed for Volume DLT-20Dec04.
620 Do not forget to mount the drive!!!
621 - Bug: if a job is manually scheduled to run later, it does not appear
622 in any status report and cannot be cancelled.
627 How about introducing a Type = MgmtPolicy job type? That job type would
628 be responsible for scanning the Bacula environment looking for specific
629 conditions, and submitting the appropriate jobs for implementing said
633 Name = "Migration-Policy"
635 Policy Selection Job Type = Migrate
636 Scope = "<keyword> <operator> <regexp>"
637 Threshold = "<keyword> <operator> <regexp>"
638 Job Template = <template-name>
641 Where <keyword> is any legal job keyword, <operator> is a comparison
642 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
643 appropriate regexp. I could see an argument for Scope and Threshold
644 being SQL queries if we want to support full flexibility. The
645 Migration-Policy job would then get scheduled as frequently as a site
646 felt necessary (suggested default: every 15 minutes).
651 Name = "Migration-Policy"
653 Policy Selection Job Type = Migration
655 Threshold = "Migration Selection Type = LowestUtil"
656 Job Template = "MigrationTemplate"
659 would select all pools for examination and generate a job based on
660 MigrationTemplate to automatically select the volume with the lowest
661 usage and migrate it's contents to the nextpool defined for that pool.
663 This policy abstraction would be really handy for adjusting the behavior
664 of Bacula according to site-selectable criteria (one thing that pops
665 into mind is Amanda's ability to automatically adjust backup levels
666 depending on various criteria).
672 - Add Pool/Storage override regression test.
673 - Add delete JobId to regression.
674 - Add a regression test for dbcheck.
675 - New test to add bscan to four-concurrent-jobs regression,
676 i.e. after the four-concurrent jobs zap the
677 database as is done in the bscan-test, then use bscan to
678 restore the database, do a restore and compare with the
680 - Add restore of specific JobId to regression (item 3
681 on the restore prompt)
682 - Add IPv6 to regression
683 - Add database test to regression. Test each function like delete,
686 - AntiVir can slow down backups on Win32 systems.
687 - Win32 systems with FAT32 can be much slower than NTFS for
688 more than 1000 files per directory.
692 - A HOLD command to stop all jobs from starting.
693 - A PAUSE command to pause all running jobs ==> release the
695 - Media Type = LTO,LTO-2,LTO-3
696 Media Type Read = LTO,LTO2,LTO3
697 Media Type Write = LTO2, LTO3
699 === From Carsten Menke <bootsy52@gmx.net>
701 Following is a list of what I think in the situations where I'm faced with,
702 could be a usefull enhancement to bacula, which I'm certain other users will
703 benefit from as well.
705 1. NextJob/NextJobs Directive within a Job Resource in the form of
706 NextJobs = job1,job2.
709 I currently solved the problem with running multiple jobs each after each
710 by setting the Max Wait Time for a job to 8 hours, and give
711 the jobs different Priorities. However, there scenarios where
712 1 Job is directly depending on another job, so if the former job fails,
713 the job after it needn't to be run
714 while maybe other jobs should run despite of that
717 A Backup Job and a Verify job, if the backup job fails there is no need to run
718 the verify job, as the backup job already failed. However, one may like
719 to backup the Catalog to disk despite of that the main backup job failed.
722 I see that this is related to the Event Handlers which are on the ToDo
723 list, also it is maybe a good idea to check for the return value and
724 execute different actions based on the return value
727 3. offline capability to bconsole
730 Currently I use a script which I execute within the last Job via the
731 RunAfterJob Directive, to release and eject the tape.
732 So I have to call bconsole "release=Storage-Name" and afterwards
733 mt -f /dev/nst0 eject to get the tape out.
735 If I have multiple Storage Devices, than these may not be /dev/nst0 and
736 I have to modify the script or call it with parameters etc.
737 This would actually not be needed, as everything is already defined
738 in bacula-sd.conf and if I can invoke bconsole with the
739 storage name via $1 in the script than I'm done and information is
742 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
746 For the reason mentioned in 3. to have the ability to call a
747 script with /scripts/foobar %s and in the script use $1
748 to pass the Storage Name to bconsole
750 5. Setting Volume State within a Job Resource
753 Instead of using "Maximum Volume Jobs" in the Pool Resource,
754 I would have the possibilty to define
755 in a Job Resource that after this certain job is run, the Volume State
756 should be set to "Volume State = Used", this give more flexibility (IMHO).
758 6. Localization of Bacula Messages
761 Unfortunatley many,many people I work with don't speak english very well.
762 So if at least the Reporting messages would be localized then they
763 would understand that they have to change the tape,etc. etc.
765 I volunteer to do the german translations, and if I can convince my wife also
766 french and Morre (western african language).
768 7. OK, this is evil, probably bound to security risks and maybe not possible
769 due to the design of bacula.
771 Implementation of Backtics ( `command` ) for shell comand execution to
772 the "Label Format" Directive.
776 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
777 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
778 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
779 the localized name for the day of the week appended to the
780 format string. Then I have the tape labeled automatically with weekday
781 name in the correct language.
783 - Make output from status use html table tags for nicely
784 presenting in a browser.
785 - Browse generations of files.
786 - I've seen an error when my catalog's File table fills up. I
787 then have to recreate the File table with a larger maximum row
788 size. Relevant information is at
789 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
790 "Installing and Configuring MySQL" chapter should talk a bit
791 about this potential problem, and recommend a solution.
792 - For Solaris must use POSIX awk.
793 - Want speed of writing to tape while despooling.
794 - Supported autochanger:
802 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
803 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
804 - Add regex from http://www.pcre.org to Bacula for Win32.
805 - Use only shell tools no make in CDROM package.
806 - Include within include does it work?
807 - Implement a Pool of type Cleaning?
808 - Implement VolReadTime and VolWriteTime in SD
809 - Modify Backing up Your Database to include a bootstrap file.
810 - Think about making certain database errors fatal.
811 - Look at correcting the time jump in the scheduler for daylight
812 savings time changes.
813 - Add a "real" timer to network connections.
814 - Promote to Full = Time period
815 - Check dates entered by user for correctness (month/day/... ranges)
816 - Compress restore Volume listing by date and first file.
817 - Look at patches/bacula_db.b2z postgresql that loops during restore.
819 - Perhaps add read/write programs and/or plugins to FileSets.
820 - How to handle backing up portables ...
821 - Add some sort of guaranteed Interval for upgrading jobs.
822 - Can we write the state file after every job terminates? On Win32
823 the system crashes and the state file is not updated.
826 Documentation to do: (any release a little bit at a time)
827 - Doc to do unmount before removing magazine.
828 - Alternative to static linking "ldd prog" save all binaries listed,
829 restore them and point LD_LIBRARY_PATH to them.
830 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
831 - Document query file format.
832 - Add more documentation for bsr files.
833 - Document problems with Verify and pruning.
834 - Document how to use multiple databases.
835 - VXA drives have a "cleaning required"
836 indicator, but Exabyte recommends preventive cleaning after every 75
839 In this context, it should be noted that Exabyte has a command-line
840 vxatool utility available for free download. (The current version is
841 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
842 test the drive, unload tapes, change drive settings, flash new firmware,
844 Of particular interest in this context is that vxatool <device> -i will
845 report, among other details, the time since last cleaning in tape motion
846 minutes. This information can be retrieved (and settings changed, for
847 that matter) through the generic-SCSI device even when Bacula has the
848 regular tape device locked. (Needless to say, I don't recommend
849 changing tape settings while a job is running.)
850 - Lookup HP cleaning recommendations.
851 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
852 - Document doing table repair
855 ===================================
856 - Add macro expansions in JobDefs.
857 Run Before Job = "SomeFile %{Level} %{Client}"
858 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
859 - Use non-blocking network I/O but if no data is available, use
861 - Use gather write() for network I/O.
862 - Autorestart on crash.
863 - Add bandwidth limiting.
864 - When an error in input occurs and conio beeps, you can back
865 up through the prompt.
866 - Detect fixed tape block mode during positioning by looking at
867 block numbers in btape "test". Possibly adjust in Bacula.
868 - Fix list volumes to output volume retention in some other
869 units, perhaps via a directive.
870 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
871 with multiple priorities.
872 - If you use restore replace=never, the directory attributes for
873 non-existent directories will not be restored properly.
875 - see lzma401.zip in others directory for new compression
877 - Allow the user to select JobType for manual pruning/purging.
878 - bscan does not put first of two volumes back with all info in
880 - Figure out how to make named console messages go only to that
881 console and to the non-restricted console (new console class?).
882 - Make restricted console prompt for password if *ask* is set or
883 perhaps if password is undefined.
884 - Implement "from ISO-date/time every x hours/days/weeks/months" in
887 ==== from Marc Schoechlin
888 - the help-command should be more verbose
889 (it should explain the paramters of the different
891 -> its time-comsuming to consult the manual anytime
892 you need a special parameter
893 -> maybe its more easy to maintain this, if the
894 descriptions of that commands are outsourced to
896 - if the password is not configured in bconsole.conf
897 you should be asked for it.
898 -> sometimes you like to do restore on a customer-machine
899 which shouldnt know the password for bacula.
900 -> adding the password to the file favours admins
901 to forget to remove the password after usage
903 the protection of that file is less important
904 - long-listed-output of commands should be scrollable
905 like the unix more/less-command does
906 -> if someone runs 200 and more machines, the lists could
907 be a little long and complex
908 - command-output should be shown column by column
909 to reduce scrolling and to increase clarity
911 - lsmark should list the selected files with full
913 - wildcards for selecting and file and directories would be nice
914 - any actions should be interuptable with STRG+C
915 - command-expansion would be pretty cool
917 - When the replace Never option is set, new directory permissions
918 are not restored. See bug 213. To fix this requires creating a
919 list of newly restored directories so that those directory
920 permissions *can* be restored.
921 - Add prune all command
922 - Document fact that purge can destroy a part of a restore by purging
923 one volume while others remain valid -- perhaps mark Jobs.
924 - Add multiple-media-types.txt
925 - look at mxt-changer.html
926 - Make ? do a help command (no return needed).
927 - Implement restore directory.
928 - Document streams and how to implement them.
929 - Try not to re-backup a file if a new hard link is added.
930 - Add feature to backup hard links only, but not the data.
931 - Fix stream handling to be simpler.
932 - Add Priority and Bootstrap to Run a Job.
933 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
935 - Remove View FileSet button from Run a Job dialog.
936 - Handle prompt for restore job at end of Restore command.
937 - Add display of total selected files to Restore window.
938 - Add tree pane to left of window.
939 - Add progress meter.
940 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
941 - Add message to user to check for fixed block size when the forward
942 space test fails in btape.
943 - When unmarking a directory check if all files below are unmarked and
944 then remove the + flag -- in the restore tree.
945 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
946 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
947 - Revisit the question of multiple Volumes (disk) on a single device.
948 - Add a block copy option to bcopy.
949 - Fix "llist jobid=xx" where no fileset or client exists.
950 - For each job type (Admin, Restore, ...) require only the really necessary
951 fields.- Pass Director resource name as an option to the Console.
952 - Add a "batch" mode to the Console (no unsolicited queries, ...).
953 - Allow browsing the catalog to see all versions of a file (with
954 stat data on each file).
955 - Restore attributes of directory if replace=never set but directory
957 - Use SHA1 on authentication if possible.
958 - See comtest-xxx.zip for Windows code to talk to USB.
959 - Add John's appended files:
960 Appended = { /files/server/logs/http/*log }
961 and such files would be treated as follows.On a FULL backup, they would
962 be backed up like any other file.On an INCREMENTAL backup, where a
963 previous INCREMENTAL or FULL was already in thecatalogue and the length
964 of the file wasgreater than the length of the last backup, only thedata
965 added since the last backup will be dumped.On an INCREMENTAL backup, if
966 the length of the file is less than thelength of the file with the same
967 name last backed up, the completefile is dumped.On Windows systems, with
968 creation date of files, we can be evensmarter about this and not count
969 entirely upon the length.On a restore, the full and all incrementals
970 since it will beapplied in sequence to restore the file.
971 - Check new HAVE_WIN32 open bits.
972 - Check if the tape has moved before writing.
973 - Handling removable disks -- see below:
974 - Add FromClient and ToClient keywords on restore command (or
975 BackupClient RestoreClient).
976 - Implement a JobSet, which groups any number of jobs. If the
977 JobSet is started, all the jobs are started together.
978 Allow Pool, Level, and Schedule overrides.
979 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
980 correctly for multiple simultaneous jobs.
981 - Implement the Media record flag that indicates that the Volume does disk
983 - Implement VolAddr, which is used when Volume is addressed like a disk,
984 and form it from VolFile and VolBlock.
985 - Fix fast block rejection (stored/read_record.c:118). It passes a null
986 pointer (rec) to try_repositioning().
987 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
988 which would take precidence over the Catalog "JobRetention".
989 - Implement Label Format in Add and Label console commands.
990 - Put email tape request delays on one or more variables. User wants
991 to cancel the job after a certain time interval. Maximum Mount Wait?
992 - Job, Client, Device, Pool, or Volume?
993 Is it possible to make this a directive which is *optional* in multiple
994 resources, like Level? If so, I think I'd make it an optional directive
995 in Job, Client, and Pool, with precedence such that Job overrides Client
996 which in turn overrides Pool.
998 - New Storage specifications:
999 - Want to write to multiple storage devices simultaneously
1000 - Want to write to multiple storage devices sequentially (in one job)
1001 - Want to read/write simultaneously
1002 - Key is MediaType -- it must match
1004 Passed to SD as a sort of BSR record called Storage Specification
1008 MediaType -> Next MediaType
1010 Device -> Next Device
1012 Allow multiple Storage specifications
1020 Allow Multiple Pool specifications (note, Pool currently
1022 Allow Multiple MediaType specifications in Dir conf
1023 Allow Multiple Device specifications in Dir conf
1024 Perhaps keep this in a single SSR
1025 Tie a Volume to a specific device by using a MediaType that
1026 is contained in only one device.
1027 In SD allow Device to have Multiple MediaTypes
1029 - Ideas from Jerry Scharf:
1030 First let's point out some big pluses that bacula has for this
1032 more importantly it's active. Thank you so much for that
1033 even more important, it's not flaky
1034 it has an open access catalog, opening many possibilities
1035 it's pushing toward heterogeneous systems capability
1037 Macintosh file client
1038 macs are an interesting niche, but I fear a server is a rathole
1039 working bare iron recovery for windows
1040 the option for inc/diff backups not reset on fileset revision
1041 a) use both change and inode update time against base time
1042 b) do the full catalog check (expensive but accurate)
1043 sizing guide (how much system is needed to back up N systems/files)
1044 consultants on using bacula in building a disaster recovery system
1045 an integration guide
1046 or how to get at fancy things that one could do with bacula
1047 logwatch code for bacula logs (or similar)
1048 linux distro inclusion of bacula (brings good and bad, but necessary)
1049 win2k/XP server capability (icky but you asked)
1050 support for Oracle database ??
1052 - Look at adding SQL server and Exchange support for Windows.
1053 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1054 is needed to properly specify ranges.
1055 - Add progress of files/bytes to SD and FD.
1056 - Print warning message if FileId > 4 billion
1057 - do a "messages" before the first prompt in Console
1058 - Client does not show busy during Estimate command.
1059 - Implement Console mtx commands.
1060 - Implement a Mount Command and an Unmount Command where
1061 the users could specify a system command to be performed
1062 to do the mount, after which Bacula could attempt to
1063 read the device. This is for Removeable media such as a CDROM.
1064 - Most likely, this mount command would be invoked explicitly
1065 by the user using the current Console "mount" and "unmount"
1066 commands -- the Storage Daemon would do the right thing
1067 depending on the exact nature of the device.
1068 - As with tape drives, when Bacula wanted a new removable
1069 disk mounted, it would unmount the old one, and send a message
1070 to the user, who would then use "mount" as described above
1071 once he had actually inserted the disk.
1072 - Implement dump/print label to UA
1073 - Spool to disk only when the tape is full, then when a tape is hung move
1075 - bextract is sending everything to the log file ****FIXME****
1076 - Allow multiple Storage specifications (or multiple names on
1077 a single Storage specification) in the Job record. Thus a job
1078 can be backed up to a number of storage devices.
1079 - Implement some way for the File daemon to contact the Director
1080 to start a job or pass its DHCP obtained IP number.
1081 - Implement a query tape prompt/replace feature for a console
1082 - Make sure that Bacula rechecks the tape after the 20 min wait.
1083 - Set IO_NOWAIT on Bacula TCP/IP packets.
1084 - Try doing a raw partition backup and restore by mounting a
1086 - From Lars Kellers:
1087 Yes, it would allow to highly automatic the request for new tapes. If a
1088 tape is empty, bacula reads the barcodes (native or simulated), and if
1089 an unused tape is found, it runs the label command with all the
1090 necessary parameters.
1092 By the way can bacula automatically "move" an empty/purged volume say
1093 in the "short" pool to the "long" pool if this pool runs out of volume
1095 - What to do about "list files job=xxx".
1096 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1097 file descriptor leak in Bacula.
1098 - Can we dynamically change FileSets?
1099 - If pool specified to label command and Label Format is specified,
1100 automatically generate the Volume name.
1101 - Add ExhautiveRestoreSearch
1102 - Look at the possibility of loading only the necessary
1103 data into the restore tree (i.e. do it one directory at a
1104 time as the user walks through the tree).
1105 - Possibly use the hash code if the user selects all for a restore command.
1106 - Fix "restore all" to bypass building the tree.
1107 - Prohibit backing up archive device (findlib/find_one.c:128)
1108 - Implement Release Device in the Job resource to unmount a drive.
1109 - Implement Acquire Device in the Job resource to mount a drive,
1110 be sure this works with admin jobs so that the user can get
1111 prompted to insert the correct tape. Possibly some way to say to
1112 run the job but don't save the files.
1113 - Make things like list where a file is saved case independent for
1115 - Implement a Recycle command
1116 - Start working on Base jobs.
1117 - From Phil Stracchino:
1118 It would probably be a per-client option, and would be called
1119 something like, say, "Automatically purge obsoleted jobs". What it
1120 would do is, when you successfully complete a Differential backup of a
1121 client, it would automatically purge all Incremental backups for that
1122 client that are rendered redundant by that Differential. Likewise,
1123 when a Full backup on a client completed, it would automatically purge
1124 all Differential and Incremental jobs obsoleted by that Full backup.
1125 This would let people minimize the number of tapes they're keeping on
1126 hand without having to master the art of retention times.
1127 - When doing a Backup send all attributes back to the Director, who
1128 would then figure out what files have been deleted.
1129 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1130 explicit permission to do so. It should also mark the tape in error
1131 if there is an error.
1132 - Cancel waiting for Client connect in SD if FD goes away.
1134 - Implement timeout in response() when it should come quickly.
1135 - Implement a Slot priority (loaded/not loaded).

1254 report resource where report=group of messages
1255 - enhance scan_attrib and rename scan_jobtype, and
1256 fill in code for "since" option
1257 - Director needs a time after which the report status is sent
1258 anyway -- or better yet, a retry time for the job.
1259 - Don't reschedule a job if previous incarnation is still running.
1260 - Some way to automatically backup everything is needed????
1261 - Need a structure for pending actions:
1263 - termination status (part of buffered msgs?)
1265 Read, Write, Clean, Delete
1266 - Login to Bacula; Bacula users with different permissions:
1267 owner, group, user, quotas
1268 - Store info on each file system type (probably in the job header on tape.
1269 This could be the output of df; or perhaps some sort of /etc/mtab record.
1271 ========= ideas ===============
1272 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1273 To: <kern@sibbald.com>
1274 Subject: RE: [Bacula-users] future large programming jobs
1275 Date: Thu, 26 Feb 2004 11:34:54 -0600
1277 I noticed the subject thread and thought I would offer the following
1278 merely as sources of ideas, i.e. something to think about, not even as
1279 strong as a request. In my former life (before retiring) I often
1280 dealt with backups and storage management issues/products as a
1281 developer and as a consultant. I am currently migrating my personal
1282 network from amanda to bacula specifically because of the ability to
1283 cross media boundaries during storing backups.
1284 Are you familiar with the commercial product called ADSM (I think IBM
1285 now sells it under the Tivoli label)? It has a couple of interesting
1286 ideas that may apply to the following topics.
1288 1. Migration: Consider that when you need to restore a system, there
1289 may be pressure to hurry. If all the information for a single client
1290 can eventually end up on the same media (and in chronological order),
1291 the restore is facillitated by not having to search past information
1292 from other clients. ADSM has the concept of "client affinity" that
1293 may be associated with it's storage pools. It seems to me that this
1294 concept (as an optional feature) might fit in your architecture for
1297 ADSM also has the concept of defining one or more storage pools as
1298 "copy pools" (almost mirrors, but only in the sense of contents).
1299 These pools provide the ability to have duplicte data stored both
1300 onsite and offsite. The copy process can be scheduled to be handled
1301 by their storage manager during periods when there is no backup
1302 activity. Again, the migration process might be a place to consider
1303 implementing something like this.
1306 > It strikes me that it would be very nice to be able to do things

1314 > mechanism described below would probably make it very easy.
1316 This is the goal. In the first step (before events), you simply
1318 the Migration to tape later.
1320 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1321 the database. Once a file (unique by path and metadata such as dates,
1322 size, ownership, etc.) is in a copy pool, no more copies are made. In
1323 other words, when you start ADSM, it begins like your concept of a
1324 base job. After that it is in the "incremental" mode. You can
1325 configure the number of "generations" of files to be retained, plus a
1326 retention date after which even old generations are purged. The
1327 database tracks the contents of media and projects the percentage of
1328 each volume that is valid. When the valid content of a volume drops
1329 below a configured percentage, the valid data are migrated to another
1330 volume and the old volume is marked as empty. Note, this requires
1331 ADSM to have an idea of the contents of a client, i.e. marking the
1332 database when an existing file was deleted, but this would solve your
1333 issue of restoring a client without restoring deleted files.
1335 This is pretty far from what bacula now does, but if you are going to
1336 rip things up for Base jobs,.....
1337 Also, the benefits of this are huge for very large shops, especially
1338 with media robots, but are a pain for shops with manual media
1342 > Base jobs sound pretty useful, but I'm not dying for them.
1344 Nobody is dying for them, but when you see what it does, you will die
1350 ==============================
1353 - Implement FSM (File System Modules).
1354 - Audit M_ error codes to ensure they are correct and consistent.
1355 - Add variable break characters to lex analyzer.
1356 Either a bit mask or a string of chars so that
1357 the caller can change the break characters.
1358 - Make a single T_BREAK to replace T_COMMA, etc.
1359 - Ensure that File daemon and Storage daemon can
1360 continue a save if the Director goes down (this
1361 is NOT currently the case). Must detect socket error,
1362 buffer messages for later.
1363 - Add ability to backup to two Storage devices (two SD sessions) at
1364 the same time -- e.g. onsite, offsite.
1366 ======================================================
1368 It is somewhat like a Full save becomes an incremental since
1369 the Base job (or jobs) plus other non-base files.
1371 - A Base backup is same as Full backup, just different type.
1372 - New BaseFiles table that contains:
1374 BaseJobId - Base JobId referenced for this FileId (needed ???)
1375 JobId - JobId currently running
1376 FileId - File not backed up, exists in Base Job
1377 FileIndex - FileIndex from Base Job.
1378 i.e. for each base file that exists but is not saved because
1379 it has not changed, the File daemon sends the JobId, BaseId,
1380 FileId, FileIndex back to the Director who creates the DB entry.
1381 - To initiate a Base save, the Director sends the FD
1382 the FileId, and full filename for each file in the Base.
1383 - When the FD finds a Base file, he requests the Director to
1384 send him the full File entry (stat packet plus MD5), or
1385 conversely, the FD sends it to the Director and the Director
1386 says yes or no. This can be quite rapid if the FileId is kept
1387 by the FD for each Base Filename.
1388 - It is probably better to have the comparison done by the FD
1389 despite the fact that the File entry must be sent across the
1391 - An alternative would be to send the FD the whole File entry
1392 from the start. The disadvantage is that it requires a lot of
1393 space. The advantage is that it requires less communications
1395 - The Job record must be updated to indicate that one or more
1397 - At end of Job, FD returns:
1398 1. Count of base files/bytes not written to tape (i.e. matches)
1399 2. Count of base file that were saved i.e. had changed.
1400 - No tape record would be written for a Base file that matches, in the
1401 same way that no tape record is written for Incremental jobs where
1402 the file is not saved because it is unchanged.
1403 - On a restore, all the Base file records must explicitly be
1404 found from the BaseFile tape. I.e. for each Full save that is marked
1405 to have one or more Base Jobs, search the BaseFile for all occurrences
1407 - An optimization might be to make the BaseFile have:
1413 This would avoid the need to explicitly fetch each File record for
1414 the Base job. The Base Job record will be fetched to get the
1415 VolSessionId and VolSessionTime.

1419 Handling removable disks
1421 From: Karl Cunningham <karlc@keckec.com>
1423 My backups are only to hard disk these days, in removable bays. This is my
1424 idea of how a backup to hard disk would work more smoothly. Some of these
1425 things Bacula does already, but I mention them for completeness. If others
1426 have better ways to do this, I'd like to hear about it.
1428 1. Accommodate several disks, rotated similar to how tapes are. Identified
1429 by partition volume ID or perhaps by the name of a subdirectory.
1430 2. Abort & notify the admin if the wrong disk is in the bay.
1431 3. Write backups to different subdirectories for each machine to be backed
1433 4. Volumes (files) get created as needed in the proper subdirectory, one
1435 5. When a disk is recycled, remove or zero all old backup files. This is
1436 important as the disk being recycled may be close to full. This may be
1437 better done manually since the backup files for many machines may be
1438 scattered in many subdirectories.
1445 - Fix bpipe.c so that it does not modify results pointer.
1446 ***FIXME*** calling sequence should be changed.
