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)

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 - Autolabel only if Volume catalog information indicates tape not
75 written. This will avoid overwriting a tape that gets an I/O
76 error on reading the volume label.
77 - Can be posible modify package to create and use configuration files in
82 /etc/bacula/bacula-dir.conf
83 /etc/bacula/conf.d/pools.conf
84 /etc/bacula/conf.d/clients.conf
85 /etc/bacula/conf.d/storages.conf
87 and into bacula-dir.conf file include
89 @/etc/bacula/conf.d/pools.conf
90 @/etc/bacula/conf.d/clients.conf
91 @/etc/bacula/conf.d/storages.conf
92 - Possibly add an Inconsistent state when a Volume is in error
94 - Fix #ifdefing so that smartalloc can be disabled. Check manual
95 -- the default is enabled.
96 - Change calling sequence to delete_job_id_range() in ua_cmds.c
97 the preceding strtok() is done inside the subroutine only once.
98 - Dangling softlinks are not restored properly. For example, take a
99 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
100 move the directory to another machine where the file /usr/share/autoconf does
101 not exist, back it up, then try a full restore. It fails.
102 - Softlinks that point to non-existent file are not restored in restore all,
103 but are restored if the file is individually selected. BUG!
104 - New directive "Delete purged Volumes"
106 - Prune by Job Level (Full, Differential, Incremental)
107 - Strict automatic pruning
108 - Implement unmount of USB volumes.
109 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
110 Win32 to avoid patent problems.
111 - Implement multiple jobid specification for the cancel command,
112 similar to what is permitted on the update slots command.
113 - Implement Bacula plugins -- design API
114 - modify pruning to keep a fixed number of versions of a file,
116 - the cd-command should allow complete paths
117 i.e. cd /foo/bar/foo/bar
118 -> if a customer mails me the path to a certain file,
119 its faster to enter the specified directory
120 - Make tree walk routines like cd, ls, ... more user friendly
121 by handling spaces better.
125 MA = (last_MA * 3 + rate) / 4
126 rate = (bytes - last_bytes) / (runtime - last_runtime)
127 - Add a recursive mark command (rmark) to restore.
128 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
129 of the same level and does not permit multiple simultaneous
130 running of that Job (i.e. lets any previous invocation finish
131 before doing Interval testing).
132 - Look at simplifying File exclusions.
134 - Auto update of slot:
135 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
136 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

141 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
142 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.

144 - Separate Files and Directories in catalog
145 - Create FileVersions table
146 - Look at rsysnc for incremental updates and dedupping
147 - Add MD5 or SHA1 check in SD for data validation
148 - finish implementation of fdcalled -- see ua_run.c:105
149 - Fix problem in postgresql.c in my_postgresql_query, where the
150 generation of the error message doesn't differentiate result==NULL
151 and a bad status from that result. Not only that, the result is
152 cleared on a bail_out without having generated the error message.
154 - Implement SDErrors (must return from SD)
155 - Implement USB keyboard support in rescue CD.
156 - Implement continue spooling while despooling.
157 - Remove all install temp files in Win32 PLUGINSDIR.
158 - Audit retention periods to make sure everything is 64 bit.
159 - No where in restore causes kaboom.
160 - Performance: multiple spool files for a single job.
161 - Performance: despool attributes when despooling data (problem
162 multiplexing Dir connection).
163 - Make restore use the in-use volume reservation algorithm.
164 - When Pool specifies Storage command override does not work.
165 - Implement wait_for_sysop() message display in wait_for_device(), which
166 now prints warnings too often.
167 - Ensure that each device in an Autochanger has a different
169 - Look at sg_logs -a /dev/sg0 for getting soft errors.
170 - btape "test" command with Offline on Unmount = yes
172 This test is essential to Bacula.
174 I'm going to write one record in file 0,
175 two records in file 1,
176 and three records in file 2
178 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715

181 Kaboom! btape, btape got signal 11. Attempting traceback.
183 - Encryption -- email from Landon
184 > The backup encryption algorithm is currently not configurable, and is
185 > set to AES_128_CBC in src/filed/backup.c. The encryption code
186 > supports a number of different ciphers (as well as adding arbitrary
187 > new ones) -- only a small bit of code would be required to map a
188 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is

191 - Figure out some way to "automatically" backup conf changes.
192 - Add the OS version back to the Win32 client info.
193 - Restarted jobs have a NULL in the from field.
194 - Modify SD status command to indicate when the SD is writing
195 to a DVD (the device is not open -- see bug #732).
196 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
197 and possibly changing the blobs into varchar.
198 - Ensure that the SD re-reads the Media record if the JobFiles
199 does not match -- it may have been updated by another job.
201 - Test Volume compatibility between machine architectures
202 - Encryption documentation
203 - Wrong jobbytes with query 12 (todo)
204 - Bare-metal recovery Windows (todo)
209 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
211 - Maximum number of scratch volumes
213 - Next Pool (already have)
214 - Reclamation threshold
216 - Reuse delay (after all files purged from volume before it can be used)
217 - Copy Pool = xx, yyy (or multiple lines).
219 - Allow pool selection during restore.
221 - Average tape size from Eric
222 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg

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

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

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

604 askdir.c:219 NULL Volume name. This shouldn't happen!!!
605 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
606 Label command failed for Volume DLT-20Dec04.
607 Do not forget to mount the drive!!!
608 - Bug: if a job is manually scheduled to run later, it does not appear
609 in any status report and cannot be cancelled.
614 How about introducing a Type = MgmtPolicy job type? That job type would
615 be responsible for scanning the Bacula environment looking for specific
616 conditions, and submitting the appropriate jobs for implementing said
620 Name = "Migration-Policy"
622 Policy Selection Job Type = Migrate
623 Scope = "<keyword> <operator> <regexp>"
624 Threshold = "<keyword> <operator> <regexp>"
625 Job Template = <template-name>
628 Where <keyword> is any legal job keyword, <operator> is a comparison
629 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
630 appropriate regexp. I could see an argument for Scope and Threshold
631 being SQL queries if we want to support full flexibility. The
632 Migration-Policy job would then get scheduled as frequently as a site
633 felt necessary (suggested default: every 15 minutes).
638 Name = "Migration-Policy"
640 Policy Selection Job Type = Migration
642 Threshold = "Migration Selection Type = LowestUtil"
643 Job Template = "MigrationTemplate"
646 would select all pools for examination and generate a job based on
647 MigrationTemplate to automatically select the volume with the lowest
648 usage and migrate it's contents to the nextpool defined for that pool.
650 This policy abstraction would be really handy for adjusting the behavior
651 of Bacula according to site-selectable criteria (one thing that pops
652 into mind is Amanda's ability to automatically adjust backup levels
653 depending on various criteria).
659 - Add Pool/Storage override regression test.
660 - Add delete JobId to regression.
661 - Add a regression test for dbcheck.
662 - New test to add bscan to four-concurrent-jobs regression,
663 i.e. after the four-concurrent jobs zap the
664 database as is done in the bscan-test, then use bscan to
665 restore the database, do a restore and compare with the
667 - Add restore of specific JobId to regression (item 3
668 on the restore prompt)
669 - Add IPv6 to regression
670 - Add database test to regression. Test each function like delete,
673 - AntiVir can slow down backups on Win32 systems.
674 - Win32 systems with FAT32 can be much slower than NTFS for
675 more than 1000 files per directory.
679 - A HOLD command to stop all jobs from starting.
680 - A PAUSE command to pause all running jobs ==> release the
682 - Media Type = LTO,LTO-2,LTO-3
683 Media Type Read = LTO,LTO2,LTO3
684 Media Type Write = LTO2, LTO3
686 === From Carsten Menke <bootsy52@gmx.net>
688 Following is a list of what I think in the situations where I'm faced with,
689 could be a usefull enhancement to bacula, which I'm certain other users will
690 benefit from as well.
692 1. NextJob/NextJobs Directive within a Job Resource in the form of
693 NextJobs = job1,job2.
696 I currently solved the problem with running multiple jobs each after each
697 by setting the Max Wait Time for a job to 8 hours, and give
698 the jobs different Priorities. However, there scenarios where
699 1 Job is directly depending on another job, so if the former job fails,
700 the job after it needn't to be run
701 while maybe other jobs should run despite of that
704 A Backup Job and a Verify job, if the backup job fails there is no need to run
705 the verify job, as the backup job already failed. However, one may like
706 to backup the Catalog to disk despite of that the main backup job failed.
709 I see that this is related to the Event Handlers which are on the ToDo
710 list, also it is maybe a good idea to check for the return value and
711 execute different actions based on the return value
714 3. offline capability to bconsole
717 Currently I use a script which I execute within the last Job via the
718 RunAfterJob Directive, to release and eject the tape.
719 So I have to call bconsole "release=Storage-Name" and afterwards
720 mt -f /dev/nst0 eject to get the tape out.
722 If I have multiple Storage Devices, than these may not be /dev/nst0 and
723 I have to modify the script or call it with parameters etc.
724 This would actually not be needed, as everything is already defined
725 in bacula-sd.conf and if I can invoke bconsole with the
726 storage name via $1 in the script than I'm done and information is
729 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
733 For the reason mentioned in 3. to have the ability to call a
734 script with /scripts/foobar %s and in the script use $1
735 to pass the Storage Name to bconsole
737 5. Setting Volume State within a Job Resource
740 Instead of using "Maximum Volume Jobs" in the Pool Resource,
741 I would have the possibilty to define
742 in a Job Resource that after this certain job is run, the Volume State
743 should be set to "Volume State = Used", this give more flexibility (IMHO).
745 6. Localization of Bacula Messages
748 Unfortunatley many,many people I work with don't speak english very well.
749 So if at least the Reporting messages would be localized then they
750 would understand that they have to change the tape,etc. etc.
752 I volunteer to do the german translations, and if I can convince my wife also
753 french and Morre (western african language).
755 7. OK, this is evil, probably bound to security risks and maybe not possible
756 due to the design of bacula.
758 Implementation of Backtics ( `command` ) for shell comand execution to
759 the "Label Format" Directive.
763 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
764 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
765 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
766 the localized name for the day of the week appended to the
767 format string. Then I have the tape labeled automatically with weekday
768 name in the correct language.
770 - Make output from status use html table tags for nicely
771 presenting in a browser.
772 - Browse generations of files.
773 - I've seen an error when my catalog's File table fills up. I
774 then have to recreate the File table with a larger maximum row
775 size. Relevant information is at
776 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
777 "Installing and Configuring MySQL" chapter should talk a bit
778 about this potential problem, and recommend a solution.
779 - For Solaris must use POSIX awk.
780 - Want speed of writing to tape while despooling.
781 - Supported autochanger:
789 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
790 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
791 - Add regex from http://www.pcre.org to Bacula for Win32.
792 - Use only shell tools no make in CDROM package.
793 - Include within include does it work?
794 - Implement a Pool of type Cleaning?
795 - Implement VolReadTime and VolWriteTime in SD
796 - Modify Backing up Your Database to include a bootstrap file.
797 - Think about making certain database errors fatal.
798 - Look at correcting the time jump in the scheduler for daylight
799 savings time changes.
800 - Add a "real" timer to network connections.
801 - Promote to Full = Time period
802 - Check dates entered by user for correctness (month/day/... ranges)
803 - Compress restore Volume listing by date and first file.
804 - Look at patches/bacula_db.b2z postgresql that loops during restore.
806 - Perhaps add read/write programs and/or plugins to FileSets.
807 - How to handle backing up portables ...
808 - Add some sort of guaranteed Interval for upgrading jobs.
809 - Can we write the state file after every job terminates? On Win32
810 the system crashes and the state file is not updated.
813 Documentation to do: (any release a little bit at a time)
814 - Doc to do unmount before removing magazine.
815 - Alternative to static linking "ldd prog" save all binaries listed,
816 restore them and point LD_LIBRARY_PATH to them.
817 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
818 - Document query file format.
819 - Add more documentation for bsr files.
820 - Document problems with Verify and pruning.
821 - Document how to use multiple databases.
822 - VXA drives have a "cleaning required"
823 indicator, but Exabyte recommends preventive cleaning after every 75
826 In this context, it should be noted that Exabyte has a command-line
827 vxatool utility available for free download. (The current version is
828 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
829 test the drive, unload tapes, change drive settings, flash new firmware,
831 Of particular interest in this context is that vxatool <device> -i will
832 report, among other details, the time since last cleaning in tape motion
833 minutes. This information can be retrieved (and settings changed, for
834 that matter) through the generic-SCSI device even when Bacula has the
835 regular tape device locked. (Needless to say, I don't recommend
836 changing tape settings while a job is running.)
837 - Lookup HP cleaning recommendations.
838 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
839 - Document doing table repair
842 ===================================
843 - Add macro expansions in JobDefs.
844 Run Before Job = "SomeFile %{Level} %{Client}"
845 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
846 - Use non-blocking network I/O but if no data is available, use
848 - Use gather write() for network I/O.
849 - Autorestart on crash.
850 - Add bandwidth limiting.
851 - When an error in input occurs and conio beeps, you can back
852 up through the prompt.
853 - Detect fixed tape block mode during positioning by looking at
854 block numbers in btape "test". Possibly adjust in Bacula.
855 - Fix list volumes to output volume retention in some other
856 units, perhaps via a directive.
857 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
858 with multiple priorities.
859 - If you use restore replace=never, the directory attributes for
860 non-existent directories will not be restored properly.
862 - see lzma401.zip in others directory for new compression
864 - Allow the user to select JobType for manual pruning/purging.
865 - bscan does not put first of two volumes back with all info in
867 - Figure out how to make named console messages go only to that
868 console and to the non-restricted console (new console class?).
869 - Make restricted console prompt for password if *ask* is set or
870 perhaps if password is undefined.
871 - Implement "from ISO-date/time every x hours/days/weeks/months" in
874 ==== from Marc Schoechlin
875 - the help-command should be more verbose
876 (it should explain the paramters of the different
878 -> its time-comsuming to consult the manual anytime
879 you need a special parameter
880 -> maybe its more easy to maintain this, if the
881 descriptions of that commands are outsourced to
883 - if the password is not configured in bconsole.conf
884 you should be asked for it.
885 -> sometimes you like to do restore on a customer-machine
886 which shouldnt know the password for bacula.
887 -> adding the password to the file favours admins
888 to forget to remove the password after usage
890 the protection of that file is less important
891 - long-listed-output of commands should be scrollable
892 like the unix more/less-command does
893 -> if someone runs 200 and more machines, the lists could
894 be a little long and complex
895 - command-output should be shown column by column
896 to reduce scrolling and to increase clarity
898 - lsmark should list the selected files with full
900 - wildcards for selecting and file and directories would be nice
901 - any actions should be interuptable with STRG+C
902 - command-expansion would be pretty cool
904 - When the replace Never option is set, new directory permissions
905 are not restored. See bug 213. To fix this requires creating a
906 list of newly restored directories so that those directory
907 permissions *can* be restored.
908 - Add prune all command
909 - Document fact that purge can destroy a part of a restore by purging
910 one volume while others remain valid -- perhaps mark Jobs.
911 - Add multiple-media-types.txt
912 - look at mxt-changer.html
913 - Make ? do a help command (no return needed).
914 - Implement restore directory.
915 - Document streams and how to implement them.
916 - Try not to re-backup a file if a new hard link is added.
917 - Add feature to backup hard links only, but not the data.
918 - Fix stream handling to be simpler.
919 - Add Priority and Bootstrap to Run a Job.
920 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
922 - Remove View FileSet button from Run a Job dialog.
923 - Handle prompt for restore job at end of Restore command.
924 - Add display of total selected files to Restore window.
925 - Add tree pane to left of window.
926 - Add progress meter.
927 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
928 - Add message to user to check for fixed block size when the forward
929 space test fails in btape.
930 - When unmarking a directory check if all files below are unmarked and
931 then remove the + flag -- in the restore tree.
932 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
933 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
934 - Revisit the question of multiple Volumes (disk) on a single device.
935 - Add a block copy option to bcopy.
936 - Fix "llist jobid=xx" where no fileset or client exists.
937 - For each job type (Admin, Restore, ...) require only the really necessary
938 fields.- Pass Director resource name as an option to the Console.
939 - Add a "batch" mode to the Console (no unsolicited queries, ...).
940 - Allow browsing the catalog to see all versions of a file (with
941 stat data on each file).
942 - Restore attributes of directory if replace=never set but directory
944 - Use SHA1 on authentication if possible.
945 - See comtest-xxx.zip for Windows code to talk to USB.
946 - Add John's appended files:
947 Appended = { /files/server/logs/http/*log }
948 and such files would be treated as follows.On a FULL backup, they would
949 be backed up like any other file.On an INCREMENTAL backup, where a
950 previous INCREMENTAL or FULL was already in thecatalogue and the length
951 of the file wasgreater than the length of the last backup, only thedata
952 added since the last backup will be dumped.On an INCREMENTAL backup, if
953 the length of the file is less than thelength of the file with the same
954 name last backed up, the completefile is dumped.On Windows systems, with
955 creation date of files, we can be evensmarter about this and not count
956 entirely upon the length.On a restore, the full and all incrementals
957 since it will beapplied in sequence to restore the file.
958 - Check new HAVE_WIN32 open bits.
959 - Check if the tape has moved before writing.
960 - Handling removable disks -- see below:
961 - Add FromClient and ToClient keywords on restore command (or
962 BackupClient RestoreClient).
963 - Implement a JobSet, which groups any number of jobs. If the
964 JobSet is started, all the jobs are started together.
965 Allow Pool, Level, and Schedule overrides.
966 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
967 correctly for multiple simultaneous jobs.
968 - Implement the Media record flag that indicates that the Volume does disk
970 - Implement VolAddr, which is used when Volume is addressed like a disk,
971 and form it from VolFile and VolBlock.
972 - Fix fast block rejection (stored/read_record.c:118). It passes a null
973 pointer (rec) to try_repositioning().
974 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
975 which would take precidence over the Catalog "JobRetention".
976 - Implement Label Format in Add and Label console commands.
977 - Put email tape request delays on one or more variables. User wants
978 to cancel the job after a certain time interval. Maximum Mount Wait?
979 - Job, Client, Device, Pool, or Volume?
980 Is it possible to make this a directive which is *optional* in multiple
981 resources, like Level? If so, I think I'd make it an optional directive
982 in Job, Client, and Pool, with precedence such that Job overrides Client
983 which in turn overrides Pool.
985 - New Storage specifications:
986 - Want to write to multiple storage devices simultaneously
987 - Want to write to multiple storage devices sequentially (in one job)
988 - Want to read/write simultaneously
989 - Key is MediaType -- it must match
991 Passed to SD as a sort of BSR record called Storage Specification
995 MediaType -> Next MediaType
997 Device -> Next Device
999 Allow multiple Storage specifications
1007 Allow Multiple Pool specifications (note, Pool currently
1009 Allow Multiple MediaType specifications in Dir conf
1010 Allow Multiple Device specifications in Dir conf
1011 Perhaps keep this in a single SSR
1012 Tie a Volume to a specific device by using a MediaType that
1013 is contained in only one device.
1014 In SD allow Device to have Multiple MediaTypes
1016 - Ideas from Jerry Scharf:
1017 First let's point out some big pluses that bacula has for this
1019 more importantly it's active. Thank you so much for that
1020 even more important, it's not flaky
1021 it has an open access catalog, opening many possibilities
1022 it's pushing toward heterogeneous systems capability
1024 Macintosh file client
1025 macs are an interesting niche, but I fear a server is a rathole
1026 working bare iron recovery for windows
1027 the option for inc/diff backups not reset on fileset revision
1028 a) use both change and inode update time against base time
1029 b) do the full catalog check (expensive but accurate)
1030 sizing guide (how much system is needed to back up N systems/files)
1031 consultants on using bacula in building a disaster recovery system
1032 an integration guide
1033 or how to get at fancy things that one could do with bacula
1034 logwatch code for bacula logs (or similar)
1035 linux distro inclusion of bacula (brings good and bad, but necessary)
1036 win2k/XP server capability (icky but you asked)
1037 support for Oracle database ??
1039 - Look at adding SQL server and Exchange support for Windows.
1040 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1041 is needed to properly specify ranges.
1042 - Add progress of files/bytes to SD and FD.
1043 - Print warning message if FileId > 4 billion
1044 - do a "messages" before the first prompt in Console
1045 - Client does not show busy during Estimate command.
1046 - Implement Console mtx commands.
1047 - Implement a Mount Command and an Unmount Command where
1048 the users could specify a system command to be performed
1049 to do the mount, after which Bacula could attempt to
1050 read the device. This is for Removeable media such as a CDROM.
1051 - Most likely, this mount command would be invoked explicitly
1052 by the user using the current Console "mount" and "unmount"
1053 commands -- the Storage Daemon would do the right thing
1054 depending on the exact nature of the device.
1055 - As with tape drives, when Bacula wanted a new removable
1056 disk mounted, it would unmount the old one, and send a message
1057 to the user, who would then use "mount" as described above
1058 once he had actually inserted the disk.
1059 - Implement dump/print label to UA
1060 - Spool to disk only when the tape is full, then when a tape is hung move
1062 - bextract is sending everything to the log file ****FIXME****
1063 - Allow multiple Storage specifications (or multiple names on
1064 a single Storage specification) in the Job record. Thus a job
1065 can be backed up to a number of storage devices.
1066 - Implement some way for the File daemon to contact the Director
1067 to start a job or pass its DHCP obtained IP number.
1068 - Implement a query tape prompt/replace feature for a console
1069 - Make sure that Bacula rechecks the tape after the 20 min wait.
1070 - Set IO_NOWAIT on Bacula TCP/IP packets.
1071 - Try doing a raw partition backup and restore by mounting a
1073 - From Lars Kellers:
1074 Yes, it would allow to highly automatic the request for new tapes. If a
1075 tape is empty, bacula reads the barcodes (native or simulated), and if
1076 an unused tape is found, it runs the label command with all the
1077 necessary parameters.
1079 By the way can bacula automatically "move" an empty/purged volume say
1080 in the "short" pool to the "long" pool if this pool runs out of volume
1082 - What to do about "list files job=xxx".
1083 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1084 file descriptor leak in Bacula.
1085 - Can we dynamically change FileSets?
1086 - If pool specified to label command and Label Format is specified,
1087 automatically generate the Volume name.
1088 - Add ExhautiveRestoreSearch
1089 - Look at the possibility of loading only the necessary
1090 data into the restore tree (i.e. do it one directory at a
1091 time as the user walks through the tree).
1092 - Possibly use the hash code if the user selects all for a restore command.
1093 - Fix "restore all" to bypass building the tree.
1094 - Prohibit backing up archive device (findlib/find_one.c:128)
1095 - Implement Release Device in the Job resource to unmount a drive.
1096 - Implement Acquire Device in the Job resource to mount a drive,
1097 be sure this works with admin jobs so that the user can get
1098 prompted to insert the correct tape. Possibly some way to say to
1099 run the job but don't save the files.
1100 - Make things like list where a file is saved case independent for
1102 - Implement a Recycle command
1103 - Start working on Base jobs.
1104 - From Phil Stracchino:
1105 It would probably be a per-client option, and would be called
1106 something like, say, "Automatically purge obsoleted jobs". What it
1107 would do is, when you successfully complete a Differential backup of a
1108 client, it would automatically purge all Incremental backups for that
1109 client that are rendered redundant by that Differential. Likewise,
1110 when a Full backup on a client completed, it would automatically purge
1111 all Differential and Incremental jobs obsoleted by that Full backup.
1112 This would let people minimize the number of tapes they're keeping on
1113 hand without having to master the art of retention times.
1114 - When doing a Backup send all attributes back to the Director, who
1115 would then figure out what files have been deleted.
1116 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1117 explicit permission to do so. It should also mark the tape in error
1118 if there is an error.
1119 - Cancel waiting for Client connect in SD if FD goes away.
1121 - Implement timeout in response() when it should come quickly.
1122 - Implement a Slot priority (loaded/not loaded).
1123 - Implement "vacation" Incremental only saves.
1124 - Implement create "FileSet"?
1125 - Add prefixlinks to where or not where absolute links to FD.
1126 - Issue message to mount a new tape before the rewind.
1127 - Simplified client job initiation for portables.
1128 - If SD cannot open a drive, make it periodically retry.
1129 - Add more of the config info to the tape label.
1131 - Refine SD waiting output:
1132 Device is being positioned

1136 - Figure out some way to estimate output size and to avoid splitting
1137 a backup across two Volumes -- this could be useful for writing CDROMs
1138 where you really prefer not to have it split -- not serious.
1139 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1140 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1141 actual data on the Volume and compare it.
1142 - Make bcopy read through bad tape records.
1143 - Program files (i.e. execute a program to read/write files).
1144 Pass read date of last backup, size of file last time.
1145 - Add Signature type to File DB record.
1146 - CD into subdirectory when open()ing files for backup to
1147 speed up things. Test with testfind().
1148 - Priority job to go to top of list.
1149 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1150 - Implement some way for the Console to dynamically create a job.
1151 - Solaris -I on tar for include list
1152 - Need a verbose mode in restore, perhaps to bsr.
1153 - bscan without -v is too quiet -- perhaps show jobs.
1154 - Add code to reject whole blocks if not wanted on restore.
1155 - Check if we can increase Bacula FD priorty in Win2000
1156 - Check if both CatalogFiles and UseCatalog are set to SD.
1157 - Possibly add email to Watchdog if drive is unmounted too
1158 long and a job is waiting on the drive.
1159 - After unmount, if restore job started, ask to mount.
1160 - Add UA rc and history files.
1161 - put termcap (used by console) in ./configure and
1162 allow -with-termcap-dir.
1163 - Fix Autoprune for Volumes to respect need for full save.
1164 - Compare tape to Client files (attributes, or attributes and data)
1165 - Make all database Ids 64 bit.
1166 - Allow console commands to detach or run in background.
1167 - Add SD message variables to control operator wait time
1168 - Maximum Operator Wait
1169 - Minimum Message Interval
1170 - Maximum Message Interval
1171 - Send Operator message when cannot read tape label.
1172 - Verify level=Volume (scan only), level=Data (compare of data to file).
1173 Verify level=Catalog, level=InitCatalog
1175 - Add keyword search to show command in Console.
1176 - Events : tape has more than xxx bytes.
1177 - Complete code in Bacula Resources -- this will permit
1178 reading a new config file at any time.
1179 - Handle ctl-c in Console
1180 - Implement script driven addition of File daemon to config files.
1181 - Think about how to make Bacula work better with File (non-tape) archives.
1182 - Write Unix emulator for Windows.
1183 - Make database type selectable by .conf files i.e. at runtime
1184 - Set flag for uname -a. Add to Volume label.
1185 - Restore files modified after date
1186 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1187 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1188 - Timout a job or terminate if link goes down, or reopen link and query.
1189 - Concept of precious tapes (cannot be reused).
1190 - Make bcopy copy with a single tape drive.
1191 - Permit changing ownership during restore.

1205 - Autolabel should be specified by DIR instead of SD.
1207 - Add media capacity
1208 - AutoScan (check checksum of tape)
1209 - Format command = "format /dev/nst0"
1213 - Seek resolution (usually corresponds to buffer size)
1214 - EODErrorCode=ENOSPC or code
1215 - Partial Read error code
1216 - Partial write error code
1217 - Nonformatted read error
1218 - Nonformatted write error
1219 - WriteProtected error
1223 - IgnoreCloseErrors=yes
1233 - Write a Storage daemon that uses pipes and
1234 standard Unix programs to write to the tape.
1236 - Need something that monitors the JCR queue and
1237 times out jobs by asking the deamons where they are.
1238 - Enhance Jmsg code to permit buffering and saving to disk.
1239 - Verify from Volume
1240 - Need report class for messages. Perhaps
1241 report resource where report=group of messages
1242 - enhance scan_attrib and rename scan_jobtype, and
1243 fill in code for "since" option
1244 - Director needs a time after which the report status is sent
1245 anyway -- or better yet, a retry time for the job.
1246 - Don't reschedule a job if previous incarnation is still running.
1247 - Some way to automatically backup everything is needed????
1248 - Need a structure for pending actions:
1250 - termination status (part of buffered msgs?)
1252 Read, Write, Clean, Delete
1253 - Login to Bacula; Bacula users with different permissions:
1254 owner, group, user, quotas
1255 - Store info on each file system type (probably in the job header on tape.
1256 This could be the output of df; or perhaps some sort of /etc/mtab record.
1258 ========= ideas ===============
1259 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1260 To: <kern@sibbald.com>
1261 Subject: RE: [Bacula-users] future large programming jobs
1262 Date: Thu, 26 Feb 2004 11:34:54 -0600
1264 I noticed the subject thread and thought I would offer the following
1265 merely as sources of ideas, i.e. something to think about, not even as
1266 strong as a request. In my former life (before retiring) I often
1267 dealt with backups and storage management issues/products as a
1268 developer and as a consultant. I am currently migrating my personal
1269 network from amanda to bacula specifically because of the ability to
1270 cross media boundaries during storing backups.
1271 Are you familiar with the commercial product called ADSM (I think IBM
1272 now sells it under the Tivoli label)? It has a couple of interesting
1273 ideas that may apply to the following topics.
1275 1. Migration: Consider that when you need to restore a system, there
1276 may be pressure to hurry. If all the information for a single client
1277 can eventually end up on the same media (and in chronological order),
1278 the restore is facillitated by not having to search past information
1279 from other clients. ADSM has the concept of "client affinity" that
1280 may be associated with it's storage pools. It seems to me that this
1281 concept (as an optional feature) might fit in your architecture for
1284 ADSM also has the concept of defining one or more storage pools as
1285 "copy pools" (almost mirrors, but only in the sense of contents).
1286 These pools provide the ability to have duplicte data stored both
1287 onsite and offsite. The copy process can be scheduled to be handled
1288 by their storage manager during periods when there is no backup
1289 activity. Again, the migration process might be a place to consider
1290 implementing something like this.

1303 This is the goal. In the first step (before events), you simply
1305 the Migration to tape later.
1307 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1308 the database. Once a file (unique by path and metadata such as dates,
1309 size, ownership, etc.) is in a copy pool, no more copies are made. In
1310 other words, when you start ADSM, it begins like your concept of a
1311 base job. After that it is in the "incremental" mode. You can
1312 configure the number of "generations" of files to be retained, plus a
1313 retention date after which even old generations are purged. The
1314 database tracks the contents of media and projects the percentage of
1315 each volume that is valid. When the valid content of a volume drops
1316 below a configured percentage, the valid data are migrated to another
1317 volume and the old volume is marked as empty. Note, this requires
1318 ADSM to have an idea of the contents of a client, i.e. marking the
1319 database when an existing file was deleted, but this would solve your
1320 issue of restoring a client without restoring deleted files.
1322 This is pretty far from what bacula now does, but if you are going to
1323 rip things up for Base jobs,.....
1324 Also, the benefits of this are huge for very large shops, especially
1325 with media robots, but are a pain for shops with manual media
1329 > Base jobs sound pretty useful, but I'm not dying for them.
1331 Nobody is dying for them, but when you see what it does, you will die
1337 ==============================
1340 - Implement FSM (File System Modules).
1341 - Audit M_ error codes to ensure they are correct and consistent.
1342 - Add variable break characters to lex analyzer.
1343 Either a bit mask or a string of chars so that
1344 the caller can change the break characters.
1345 - Make a single T_BREAK to replace T_COMMA, etc.
1346 - Ensure that File daemon and Storage daemon can
1347 continue a save if the Director goes down (this
1348 is NOT currently the case). Must detect socket error,
1349 buffer messages for later.
1350 - Add ability to backup to two Storage devices (two SD sessions) at
1351 the same time -- e.g. onsite, offsite.
1353 ======================================================
1355 It is somewhat like a Full save becomes an incremental since
1356 the Base job (or jobs) plus other non-base files.
1358 - A Base backup is same as Full backup, just different type.
1359 - New BaseFiles table that contains:
1361 BaseJobId - Base JobId referenced for this FileId (needed ???)
1362 JobId - JobId currently running
1363 FileId - File not backed up, exists in Base Job
1364 FileIndex - FileIndex from Base Job.
1365 i.e. for each base file that exists but is not saved because
1366 it has not changed, the File daemon sends the JobId, BaseId,
1367 FileId, FileIndex back to the Director who creates the DB entry.
1368 - To initiate a Base save, the Director sends the FD
1369 the FileId, and full filename for each file in the Base.
1370 - When the FD finds a Base file, he requests the Director to
1371 send him the full File entry (stat packet plus MD5), or
1372 conversely, the FD sends it to the Director and the Director
1373 says yes or no. This can be quite rapid if the FileId is kept
1374 by the FD for each Base Filename.
1375 - It is probably better to have the comparison done by the FD
1376 despite the fact that the File entry must be sent across the
1378 - An alternative would be to send the FD the whole File entry
1379 from the start. The disadvantage is that it requires a lot of
1380 space. The advantage is that it requires less communications
1382 - The Job record must be updated to indicate that one or more
1384 - At end of Job, FD returns:
1385 1. Count of base files/bytes not written to tape (i.e. matches)
1386 2. Count of base file that were saved i.e. had changed.
1387 - No tape record would be written for a Base file that matches, in the
1388 same way that no tape record is written for Incremental jobs where
1389 the file is not saved because it is unchanged.
1390 - On a restore, all the Base file records must explicitly be
1391 found from the BaseFile tape. I.e. for each Full save that is marked
1392 to have one or more Base Jobs, search the BaseFile for all occurrences
1394 - An optimization might be to make the BaseFile have:
1400 This would avoid the need to explicitly fetch each File record for
1401 the Base job. The Base Job record will be fetched to get the
1402 VolSessionId and VolSessionTime.

1406 Handling removable disks
1408 From: Karl Cunningham <karlc@keckec.com>
1410 My backups are only to hard disk these days, in removable bays. This is my
1411 idea of how a backup to hard disk would work more smoothly. Some of these
1412 things Bacula does already, but I mention them for completeness. If others
1413 have better ways to do this, I'd like to hear about it.
1415 1. Accommodate several disks, rotated similar to how tapes are. Identified
1416 by partition volume ID or perhaps by the name of a subdirectory.
1417 2. Abort & notify the admin if the wrong disk is in the bay.
1418 3. Write backups to different subdirectories for each machine to be backed
1420 4. Volumes (files) get created as needed in the proper subdirectory, one
1422 5. When a disk is recycled, remove or zero all old backup files. This is
1423 important as the disk being recycled may be close to full. This may be
1424 better done manually since the backup files for many machines may be
1425 scattered in many subdirectories.
1432 - Fix bpipe.c so that it does not modify results pointer.
1433 ***FIXME*** calling sequence should be changed.
