22 - %d and %v only valid on Director, not for ClientRunBefore/After.
23 - During tests with the 260 char fix code, I found one problem:
24 if the system "sees" a long path once, it seems to forget it's
25 working drive (e.g. c:\), which will lead to a problem during
26 the next job (create bootstrap file will fail). Here is the
27 workaround: specify absolute working and pid directory in

80 See email of 21Aug2007 for details.
81 - Look at: http://tech.groups.yahoo.com/group/cfg2html
82 and http://www.openeyet.nl/scc/ for managing customer changes
87 - When reserving a device to read, check to see if the Volume
88 is already in use, if so wait. Probably will need to pass the
89 Volume. See bug #1313. Create a regression test to simulate
90 this problem and see if VolumePollInterval fixes it. Possibly turn
93 - Fix restore of acls and extended attributes to count ERROR
94 messages and make errors non-fatal.
95 - Put save/restore various platform acl/xattrs on a pointer to simplify
98 - Why no error message if restore has no permission on the where
100 - Possibly allow manual "purge" to purge a Volume that has not
101 yet been written (even if FirstWritten time is zero) see ua_purge.c
103 - Add disk block detection bsr code (make it work).
105 - Add blast attributes to DIR to SD.
106 - Detect deadlocks in reservations.
108 - Add list during dump
109 - Add in plugin code flag
110 - Add bRC_EndJob -- stops more calls to plugin this job
111 - Add bRC_Term (unload plugin)
112 - remove time_t from Jmsg and use utime_t?
113 - Deadlock detection, watchdog sees if counter advances when jobs are
114 running. With debug on, can do a "status" command.
115 - User options for plugins.
116 - Pool Storage override precedence over command line.
117 - Autolabel only if Volume catalog information indicates tape not
118 written. This will avoid overwriting a tape that gets an I/O
119 error on reading the volume label.
120 - I/O error, SD thinks it is not the right Volume, should check slot
121 then disable volume, but Asks for mount.
122 - Can be posible modify package to create and use configuration files in
127 /etc/bacula/bacula-dir.conf
128 /etc/bacula/conf.d/pools.conf
129 /etc/bacula/conf.d/clients.conf
130 /etc/bacula/conf.d/storages.conf
132 and into bacula-dir.conf file include
134 @/etc/bacula/conf.d/pools.conf
135 @/etc/bacula/conf.d/clients.conf
136 @/etc/bacula/conf.d/storages.conf
137 - Possibly add an Inconsistent state when a Volume is in error
139 - Fix #ifdefing so that smartalloc can be disabled. Check manual
140 -- the default is enabled.
141 - Change calling sequence to delete_job_id_range() in ua_cmds.c
142 the preceding strtok() is done inside the subroutine only once.
143 - Dangling softlinks are not restored properly. For example, take a
144 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
145 move the directory to another machine where the file /usr/share/autoconf does
146 not exist, back it up, then try a full restore. It fails.
147 - Softlinks that point to non-existent file are not restored in restore all,
148 but are restored if the file is individually selected. BUG!
149 - New directive "Delete purged Volumes"
151 - Prune by Job Level (Full, Differential, Incremental)
152 - Strict automatic pruning
153 - Implement unmount of USB volumes.
154 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
155 Win32 to avoid patent problems.
156 - Implement multiple jobid specification for the cancel command,
157 similar to what is permitted on the update slots command.
158 - modify pruning to keep a fixed number of versions of a file,
160 - the cd-command should allow complete paths
161 i.e. cd /foo/bar/foo/bar
162 -> if a customer mails me the path to a certain file,
163 its faster to enter the specified directory
164 - Make tree walk routines like cd, ls, ... more user friendly
165 by handling spaces better.
166 - When doing a restore, if the user does an "update slots"
167 after the job started in order to add a restore volume, the
168 values prior to the update slots will be put into the catalog.
169 Must retrieve catalog record merge it then write it back at the
170 end of the restore job, if we want to do this right.
174 MA = (last_MA * 3 + rate) / 4
175 rate = (bytes - last_bytes) / (runtime - last_runtime)
176 - Add a recursive mark command (rmark) to restore.
177 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
178 of the same level and does not permit multiple simultaneous
179 running of that Job (i.e. lets any previous invocation finish
180 before doing Interval testing).
181 - Look at simplifying File exclusions.
183 - Auto update of slot:
184 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
185 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

189 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
190 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
191 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.
192 02-Nov 12:58 rufus-dir JobId 10: Bacula rufus-dir 2.3.6 (26Oct07): 02-Nov-2007 12:58:51
193 - Separate Files and Directories in catalog
194 - Create FileVersions table
195 - Look at rsysnc for incremental updates and dedupping
196 - Add MD5 or SHA1 check in SD for data validation
197 - finish implementation of fdcalled -- see ua_run.c:105
198 - Fix problem in postgresql.c in my_postgresql_query, where the
199 generation of the error message doesn't differentiate result==NULL
200 and a bad status from that result. Not only that, the result is
201 cleared on a bail_out without having generated the error message.
203 - Implement SDErrors (must return from SD)
204 - Implement USB keyboard support in rescue CD.
205 - Implement continue spooling while despooling.
206 - Remove all install temp files in Win32 PLUGINSDIR.
207 - Audit retention periods to make sure everything is 64 bit.
208 - No where in restore causes kaboom.
209 - Performance: multiple spool files for a single job.
210 - Performance: despool attributes when despooling data (problem
211 multiplexing Dir connection).
212 - Make restore use the in-use volume reservation algorithm.
213 - When Pool specifies Storage command override does not work.
214 - Implement wait_for_sysop() message display in wait_for_device(), which
215 now prints warnings too often.
216 - Ensure that each device in an Autochanger has a different
218 - Look at sg_logs -a /dev/sg0 for getting soft errors.
219 - btape "test" command with Offline on Unmount = yes
221 This test is essential to Bacula.
223 I'm going to write one record in file 0,
224 two records in file 1,
225 and three records in file 2
227 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715
228 dev.c:714 Bad call to rewind. Device "LTO" (/dev/nst0) not open
229 02-Feb 11:00 btape: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation
230 Kaboom! btape, btape got signal 11. Attempting traceback.
232 - Encryption -- email from Landon
233 > The backup encryption algorithm is currently not configurable, and is
234 > set to AES_128_CBC in src/filed/backup.c. The encryption code
235 > supports a number of different ciphers (as well as adding arbitrary
236 > new ones) -- only a small bit of code would be required to map a
237 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is
238 > interested in implementing this functionality.
240 - Figure out some way to "automatically" backup conf changes.
241 - Add the OS version back to the Win32 client info.
242 - Restarted jobs have a NULL in the from field.
243 - Modify SD status command to indicate when the SD is writing
244 to a DVD (the device is not open -- see bug #732).
245 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
246 and possibly changing the blobs into varchar.
247 - Ensure that the SD re-reads the Media record if the JobFiles
248 does not match -- it may have been updated by another job.
250 - Test Volume compatibility between machine architectures
251 - Encryption documentation
252 - Wrong jobbytes with query 12 (todo)
253 - Bare-metal recovery Windows (todo)
258 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
260 - Maximum number of scratch volumes
262 - Next Pool (already have)
263 - Reclamation threshold
265 - Reuse delay (after all files purged from volume before it can be used)
266 - Copy Pool = xx, yyy (or multiple lines).
268 - Allow pool selection during restore.
270 - Average tape size from Eric
271 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
272 count(Media.MediaId) AS volnum,
273 sum(Media.VolBytes) AS voltotal,
274 Media.PoolId AS PoolId,
275 Media.MediaType AS MediaType
277 LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,
278 Media.MediaType AS MediaType
280 WHERE Media.VolStatus = 'Full'
281 GROUP BY Media.MediaType
282 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
283 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
287 - Add doc for bweb -- especially Installation
289 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
291 - Despool attributes in separate thread
294 - Check why restore repeatedly sends Rechdrs between
295 each data chunk -- according to James Harper 9Jan07.
298 - More intelligent re-run
300 - Incremental backup -- rsync, Stow
303 - Try to fix bscan not working with multiple DVD volumes bug #912.
304 - Look at mondo/mindi
305 - Make Bacula by default not backup tmpfs, procfs, sysfs, ...
306 - Fix hardlinked immutable files when linking a second file, the
307 immutable flag must be removed prior to trying to link it.
308 - Change dbcheck to tell users to use native tools for fixing
309 broken databases, and to ensure they have the proper indexes.
310 - add udev rules for Bacula devices.
311 - If a job terminates, the DIR connection can close before the
312 Volume info is updated, leaving the File count wrong.
313 - Look at why SIGPIPE during connection can cause seg fault in
314 writing the daemon message, when Dir dropped to bacula:bacula
315 - Look at zlib 32 => 64 problems.
316 - Possibly turn on St. Bernard code.
317 - Fix bextract to restore ACLs, or better yet, use common routines.
318 - Do we migrate appendable Volumes?
319 - Remove queue.c code.
320 - Print warning message if LANG environment variable does not specify
322 - New dot commands from Arno.
323 .show device=xxx lists information from one storage device, including
324 devices (I'm not even sure that information exists in the DIR...)
325 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
326 better machine-readable output like "Ok" or "Error busy"
327 .move eject device=xxx toslot=yyy the same as above, but with a new
328 target slot. The catalog should be updated accordingly.
329 .move transfer device=xxx fromslot=yyy toslot=zzz

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

395 - Look into using Dart for testing
396 http://public.kitware.com/Dart/HTML/Index.shtml
398 - Look into replacing autotools with cmake

509 If this is not a blank tape, try unmounting and remounting the Volume.
511 - http://www.dwheeler.com/essays/commercial-floss.html
512 - Add VolumeLock to prevent all but lock holder (SD) from updating
513 the Volume data (with the exception of VolumeState).
514 - The btape fill command does not seem to use the Autochanger
515 - Make Windows installer default to system disk drive.
516 - Look at using ioctl(FIOBMAP, ...) on Linux, and
517 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
518 Win32 for sparse files.
519 http://www.flexhex.com/docs/articles/sparse-files.phtml
520 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
521 - Directive: at <event> "command"
522 - Command: pycmd "command" generates "command" event. How to
523 attach to a specific job?
524 - Integrate Christopher's St. Bernard code.
525 - run_cmd() returns int should return JobId_t
526 - get_next_jobid_from_list() returns int should return JobId_t
527 - Document export LDFLAGS=-L/usr/lib64
528 - Don't attempt to restore from "Disabled" Volumes.
529 - Network error on Win32 should set Win32 error code.
530 - What happens when you rename a Disk Volume?
531 - Job retention period in a Pool (and hence Volume). The job would
533 - Look at -D_FORTIFY_SOURCE=2
534 - Add Win32 FileSet definition somewhere
535 - Look at fixing restore status stats in SD.
536 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
537 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
538 - Implement a mode that says when a hard read error is
539 encountered, read many times (as it currently does), and if the
540 block cannot be read, skip to the next block, and try again. If
541 that fails, skip to the next file and try again, ...
543 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
544 insert into LevelType (LevelType,LevelTypeLong) values
548 - Show files/second in client status output.
549 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
550 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
551 see if it become stable and I just have to supervise
553 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
554 PoolId, and when it is empty remove it.
556 - Allow Check Labels to be used with Bacula labels.
557 - "Resuming" a failed backup (lost line for example) by using the
558 failed backup as a sort of "base" job.
560 - Email to the user when the tape is about to need changing x
561 days before it needs changing.
562 - Command to show next tape that will be used for a job even
563 if the job is not scheduled.
564 - From: Arunav Mandal <amandal@trolltech.com>
565 1. When jobs are running and bacula for some reason crashes or if I do a
566 restart it remembers and jobs it was running before it crashed or restarted
567 as of now I loose all jobs if I restart it.
569 2. When spooling and in the midway if client is disconnected for instance a
570 laptop bacula completely discard the spool. It will be nice if it can write
571 that spool to tape so there will be some backups for that client if not all.
573 3. We have around 150 clients machines it will be nice to have a option to
574 upgrade all the client machines bacula version automatically.
576 4. Atleast one connection should be reserved for the bconsole so at heavy load
577 I should connect to the director via bconsole which at sometimes I can't
579 5. Another most important feature that is missing, say at 10am I manually
580 started backup of client abc and it was a full backup since client abc has
581 no backup history and at 10.30am bacula again automatically started backup of
582 client abc as that was in the schedule. So now we have 2 multiple Full
583 backups of the same client and if we again try to start a full backup of
584 client backup abc bacula won't complain. That should be fixed.
586 - For Windows disaster recovery see http://unattended.sf.net/
587 - regardless of the retention period, Bacula will not prune the
588 last Full, Diff, or Inc File data until a month after the
589 retention period for the last Full backup that was done.
590 - update volume=xxx --- add status=Full
591 - Remove old spool files on startup.
592 - Exclude SD spool/working directory.
593 - Refuse to prune last valid Full backup. Same goes for Catalog.
595 - Make a callback when Rerun failed levels is called.
596 - Give Python program access to Scheduled jobs.
597 - Add setting Volume State via Python.
598 - Python script to save with Python, not save, save with Bacula.
599 - Python script to do backup.
601 - Change the Priority, Client, Storage, JobStatus (error)
602 at the start of a job.
603 - Why is SpoolDirectory = /home/bacula/spool; not reported
604 as an error when writing a DVD?
605 - Make bootstrap file handle multiple MediaTypes (SD)
606 - Remove all old Device resource code in Dir and code to pass it
607 back in SD -- better, rework it to pass back device statistics.
608 - Check locking of resources -- be sure to lock devices where previously
609 resources were locked.
610 - The last part is left in the spool dir.
613 - In restore don't compare byte count on a raw device -- directory
614 entry does not contain bytes.
617 - Max Vols limit in Pool off by one?
618 - Implement Files/Bytes,... stats for restore job.
619 - Implement Total Bytes Written, ... for restore job.
620 - Despool attributes simultaneously with data in a separate
621 thread, rejoined at end of data spooling.
622 - 7. Implement new Console commands to allow offlining/reserving drives,
623 and possibly manipulating the autochanger (much asked for).
624 - Add start/end date editing in messages (%t %T, %e?) ...
625 - Add ClientDefs similar to JobDefs.
626 - Print more info when bextract -p accepts a bad block.
627 - Fix FD JobType to be set before RunBeforeJob in FD.
628 - Look at adding full Volume and Pool information to a Volume
629 label so that bscan can get *all* the info.
630 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
631 and there is only one volume in the pool, refuse to do it -- otherwise
632 he fills the Volume, then immediately starts reusing it.
633 - Implement copies and stripes.
634 - Add history file to console.
635 - Each file on tape creates a JobMedia record. Peter has 4 million
636 files spread over 10000 tape files and four tapes. A restore takes
637 16 hours to build the restore list.
638 - Add and option to check if the file size changed during backup.
639 - Make sure SD deletes spool files on error exit.
640 - Delete old spool files when SD starts.
641 - When labeling tapes, if you enter 000026, Bacula uses
642 the tape index rather than the Volume name 000026.
643 - Add offline tape command to Bacula console.
645 Enter MediaId or Volume name: 32
646 Enter new Volume name: DLT-20Dec04
647 Automatically selected Pool: Default
648 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

650 block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
651 Error writing final EOF to tape. This tape may not be readable.

653 askdir.c:219 NULL Volume name. This shouldn't happen!!!
654 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
655 Label command failed for Volume DLT-20Dec04.
656 Do not forget to mount the drive!!!
657 - Bug: if a job is manually scheduled to run later, it does not appear
658 in any status report and cannot be cancelled.
663 How about introducing a Type = MgmtPolicy job type? That job type would
664 be responsible for scanning the Bacula environment looking for specific
665 conditions, and submitting the appropriate jobs for implementing said
669 Name = "Migration-Policy"
671 Policy Selection Job Type = Migrate
672 Scope = "<keyword> <operator> <regexp>"
673 Threshold = "<keyword> <operator> <regexp>"
674 Job Template = <template-name>
677 Where <keyword> is any legal job keyword, <operator> is a comparison
678 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
679 appropriate regexp. I could see an argument for Scope and Threshold
680 being SQL queries if we want to support full flexibility. The
681 Migration-Policy job would then get scheduled as frequently as a site
682 felt necessary (suggested default: every 15 minutes).
687 Name = "Migration-Policy"
689 Policy Selection Job Type = Migration
691 Threshold = "Migration Selection Type = LowestUtil"
692 Job Template = "MigrationTemplate"
695 would select all pools for examination and generate a job based on
696 MigrationTemplate to automatically select the volume with the lowest
697 usage and migrate it's contents to the nextpool defined for that pool.
699 This policy abstraction would be really handy for adjusting the behavior
700 of Bacula according to site-selectable criteria (one thing that pops
701 into mind is Amanda's ability to automatically adjust backup levels
702 depending on various criteria).
708 - Add Pool/Storage override regression test.
709 - Add delete JobId to regression.
710 - Add a regression test for dbcheck.
711 - New test to add bscan to four-concurrent-jobs regression,
712 i.e. after the four-concurrent jobs zap the
713 database as is done in the bscan-test, then use bscan to
714 restore the database, do a restore and compare with the
716 - Add restore of specific JobId to regression (item 3
717 on the restore prompt)
718 - Add IPv6 to regression
719 - Add database test to regression. Test each function like delete,
722 - AntiVir can slow down backups on Win32 systems.
723 - Win32 systems with FAT32 can be much slower than NTFS for
724 more than 1000 files per directory.
728 - A HOLD command to stop all jobs from starting.
729 - A PAUSE command to pause all running jobs ==> release the
731 - Media Type = LTO,LTO-2,LTO-3
732 Media Type Read = LTO,LTO2,LTO3
733 Media Type Write = LTO2, LTO3
735 === From Carsten Menke <bootsy52@gmx.net>
737 Following is a list of what I think in the situations where I'm faced with,
738 could be a usefull enhancement to bacula, which I'm certain other users will
739 benefit from as well.
741 1. NextJob/NextJobs Directive within a Job Resource in the form of
742 NextJobs = job1,job2.
745 I currently solved the problem with running multiple jobs each after each
746 by setting the Max Wait Time for a job to 8 hours, and give
747 the jobs different Priorities. However, there scenarios where
748 1 Job is directly depending on another job, so if the former job fails,
749 the job after it needn't to be run
750 while maybe other jobs should run despite of that
753 A Backup Job and a Verify job, if the backup job fails there is no need to run
754 the verify job, as the backup job already failed. However, one may like
755 to backup the Catalog to disk despite of that the main backup job failed.
758 I see that this is related to the Event Handlers which are on the ToDo
759 list, also it is maybe a good idea to check for the return value and
760 execute different actions based on the return value
763 3. offline capability to bconsole
766 Currently I use a script which I execute within the last Job via the
767 RunAfterJob Directive, to release and eject the tape.
768 So I have to call bconsole "release=Storage-Name" and afterwards
769 mt -f /dev/nst0 eject to get the tape out.
771 If I have multiple Storage Devices, than these may not be /dev/nst0 and
772 I have to modify the script or call it with parameters etc.
773 This would actually not be needed, as everything is already defined
774 in bacula-sd.conf and if I can invoke bconsole with the
775 storage name via $1 in the script than I'm done and information is
778 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
782 For the reason mentioned in 3. to have the ability to call a
783 script with /scripts/foobar %s and in the script use $1
784 to pass the Storage Name to bconsole
786 5. Setting Volume State within a Job Resource
789 Instead of using "Maximum Volume Jobs" in the Pool Resource,
790 I would have the possibilty to define
791 in a Job Resource that after this certain job is run, the Volume State
792 should be set to "Volume State = Used", this give more flexibility (IMHO).
794 6. Localization of Bacula Messages
797 Unfortunatley many,many people I work with don't speak english very well.
798 So if at least the Reporting messages would be localized then they
799 would understand that they have to change the tape,etc. etc.
801 I volunteer to do the german translations, and if I can convince my wife also
802 french and Morre (western african language).
804 7. OK, this is evil, probably bound to security risks and maybe not possible
805 due to the design of bacula.
807 Implementation of Backtics ( `command` ) for shell comand execution to
808 the "Label Format" Directive.
812 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
813 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
814 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
815 the localized name for the day of the week appended to the
816 format string. Then I have the tape labeled automatically with weekday
817 name in the correct language.
819 - Make output from status use html table tags for nicely
820 presenting in a browser.
821 - Browse generations of files.
822 - I've seen an error when my catalog's File table fills up. I
823 then have to recreate the File table with a larger maximum row
824 size. Relevant information is at
825 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
826 "Installing and Configuring MySQL" chapter should talk a bit
827 about this potential problem, and recommend a solution.
828 - For Solaris must use POSIX awk.
829 - Want speed of writing to tape while despooling.
830 - Supported autochanger:
838 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
839 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
840 - Add regex from http://www.pcre.org to Bacula for Win32.
841 - Use only shell tools no make in CDROM package.
842 - Include within include does it work?
843 - Implement a Pool of type Cleaning?
844 - Implement VolReadTime and VolWriteTime in SD
845 - Modify Backing up Your Database to include a bootstrap file.
846 - Think about making certain database errors fatal.
847 - Look at correcting the time jump in the scheduler for daylight
848 savings time changes.
849 - Add a "real" timer to network connections.
850 - Promote to Full = Time period
851 - Check dates entered by user for correctness (month/day/... ranges)
852 - Compress restore Volume listing by date and first file.
853 - Look at patches/bacula_db.b2z postgresql that loops during restore.
855 - Perhaps add read/write programs and/or plugins to FileSets.
856 - How to handle backing up portables ...
857 - Add some sort of guaranteed Interval for upgrading jobs.
858 - Can we write the state file after every job terminates? On Win32
859 the system crashes and the state file is not updated.
862 Documentation to do: (any release a little bit at a time)
863 - Doc to do unmount before removing magazine.
864 - Alternative to static linking "ldd prog" save all binaries listed,
865 restore them and point LD_LIBRARY_PATH to them.
866 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
867 - Document query file format.
868 - Add more documentation for bsr files.
869 - Document problems with Verify and pruning.
870 - Document how to use multiple databases.
871 - VXA drives have a "cleaning required"
872 indicator, but Exabyte recommends preventive cleaning after every 75
875 In this context, it should be noted that Exabyte has a command-line
876 vxatool utility available for free download. (The current version is
877 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
878 test the drive, unload tapes, change drive settings, flash new firmware,
880 Of particular interest in this context is that vxatool <device> -i will
881 report, among other details, the time since last cleaning in tape motion
882 minutes. This information can be retrieved (and settings changed, for
883 that matter) through the generic-SCSI device even when Bacula has the
884 regular tape device locked. (Needless to say, I don't recommend
885 changing tape settings while a job is running.)
886 - Lookup HP cleaning recommendations.
887 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
888 - Document doing table repair
891 ===================================
892 - Add macro expansions in JobDefs.
893 Run Before Job = "SomeFile %{Level} %{Client}"
894 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
895 - Use non-blocking network I/O but if no data is available, use
897 - Use gather write() for network I/O.
898 - Autorestart on crash.
899 - Add bandwidth limiting.
900 - When an error in input occurs and conio beeps, you can back
901 up through the prompt.
902 - Detect fixed tape block mode during positioning by looking at
903 block numbers in btape "test". Possibly adjust in Bacula.
904 - Fix list volumes to output volume retention in some other
905 units, perhaps via a directive.
906 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
907 with multiple priorities.
908 - If you use restore replace=never, the directory attributes for
909 non-existent directories will not be restored properly.
911 - see lzma401.zip in others directory for new compression
913 - Allow the user to select JobType for manual pruning/purging.
914 - bscan does not put first of two volumes back with all info in
916 - Figure out how to make named console messages go only to that
917 console and to the non-restricted console (new console class?).
918 - Make restricted console prompt for password if *ask* is set or
919 perhaps if password is undefined.
920 - Implement "from ISO-date/time every x hours/days/weeks/months" in
923 ==== from Marc Schoechlin
924 - the help-command should be more verbose
925 (it should explain the paramters of the different
927 -> its time-comsuming to consult the manual anytime
928 you need a special parameter
929 -> maybe its more easy to maintain this, if the
930 descriptions of that commands are outsourced to
932 - if the password is not configured in bconsole.conf
933 you should be asked for it.
934 -> sometimes you like to do restore on a customer-machine
935 which shouldnt know the password for bacula.
936 -> adding the password to the file favours admins
937 to forget to remove the password after usage
939 the protection of that file is less important
940 - long-listed-output of commands should be scrollable
941 like the unix more/less-command does
942 -> if someone runs 200 and more machines, the lists could
943 be a little long and complex
944 - command-output should be shown column by column
945 to reduce scrolling and to increase clarity
947 - lsmark should list the selected files with full
949 - wildcards for selecting and file and directories would be nice
950 - any actions should be interuptable with STRG+C
951 - command-expansion would be pretty cool
953 - When the replace Never option is set, new directory permissions
954 are not restored. See bug 213. To fix this requires creating a
955 list of newly restored directories so that those directory
956 permissions *can* be restored.
957 - Add prune all command
958 - Document fact that purge can destroy a part of a restore by purging
959 one volume while others remain valid -- perhaps mark Jobs.
960 - Add multiple-media-types.txt
961 - look at mxt-changer.html
962 - Make ? do a help command (no return needed).
963 - Implement restore directory.
964 - Document streams and how to implement them.
965 - Try not to re-backup a file if a new hard link is added.
966 - Add feature to backup hard links only, but not the data.
967 - Fix stream handling to be simpler.
968 - Add Priority and Bootstrap to Run a Job.
969 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
971 - Remove View FileSet button from Run a Job dialog.
972 - Handle prompt for restore job at end of Restore command.
973 - Add display of total selected files to Restore window.
974 - Add tree pane to left of window.
975 - Add progress meter.
976 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
977 - Add message to user to check for fixed block size when the forward
978 space test fails in btape.
979 - When unmarking a directory check if all files below are unmarked and
980 then remove the + flag -- in the restore tree.
981 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
982 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
983 - Revisit the question of multiple Volumes (disk) on a single device.
984 - Add a block copy option to bcopy.
985 - Fix "llist jobid=xx" where no fileset or client exists.
986 - For each job type (Admin, Restore, ...) require only the really necessary
987 fields.- Pass Director resource name as an option to the Console.
988 - Add a "batch" mode to the Console (no unsolicited queries, ...).
989 - Allow browsing the catalog to see all versions of a file (with
990 stat data on each file).
991 - Restore attributes of directory if replace=never set but directory
993 - Use SHA1 on authentication if possible.
994 - See comtest-xxx.zip for Windows code to talk to USB.
995 - Add John's appended files:
996 Appended = { /files/server/logs/http/*log }
997 and such files would be treated as follows.On a FULL backup, they would
998 be backed up like any other file.On an INCREMENTAL backup, where a
999 previous INCREMENTAL or FULL was already in thecatalogue and the length
1000 of the file wasgreater than the length of the last backup, only thedata
1001 added since the last backup will be dumped.On an INCREMENTAL backup, if
1002 the length of the file is less than thelength of the file with the same
1003 name last backed up, the completefile is dumped.On Windows systems, with
1004 creation date of files, we can be evensmarter about this and not count
1005 entirely upon the length.On a restore, the full and all incrementals
1006 since it will beapplied in sequence to restore the file.
1007 - Check new HAVE_WIN32 open bits.
1008 - Check if the tape has moved before writing.
1009 - Handling removable disks -- see below:
1010 - Add FromClient and ToClient keywords on restore command (or
1011 BackupClient RestoreClient).
1012 - Implement a JobSet, which groups any number of jobs. If the
1013 JobSet is started, all the jobs are started together.
1014 Allow Pool, Level, and Schedule overrides.
1015 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1016 correctly for multiple simultaneous jobs.
1017 - Implement the Media record flag that indicates that the Volume does disk
1019 - Implement VolAddr, which is used when Volume is addressed like a disk,
1020 and form it from VolFile and VolBlock.
1021 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1022 pointer (rec) to try_repositioning().
1023 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1024 which would take precidence over the Catalog "JobRetention".
1025 - Implement Label Format in Add and Label console commands.
1026 - Put email tape request delays on one or more variables. User wants
1027 to cancel the job after a certain time interval. Maximum Mount Wait?
1028 - Job, Client, Device, Pool, or Volume?
1029 Is it possible to make this a directive which is *optional* in multiple
1030 resources, like Level? If so, I think I'd make it an optional directive
1031 in Job, Client, and Pool, with precedence such that Job overrides Client
1032 which in turn overrides Pool.
1034 - New Storage specifications:
1035 - Want to write to multiple storage devices simultaneously
1036 - Want to write to multiple storage devices sequentially (in one job)
1037 - Want to read/write simultaneously
1038 - Key is MediaType -- it must match
1040 Passed to SD as a sort of BSR record called Storage Specification
1044 MediaType -> Next MediaType
1046 Device -> Next Device
1048 Allow multiple Storage specifications
1056 Allow Multiple Pool specifications (note, Pool currently
1058 Allow Multiple MediaType specifications in Dir conf
1059 Allow Multiple Device specifications in Dir conf
1060 Perhaps keep this in a single SSR
1061 Tie a Volume to a specific device by using a MediaType that
1062 is contained in only one device.
1063 In SD allow Device to have Multiple MediaTypes
1065 - Ideas from Jerry Scharf:
1066 First let's point out some big pluses that bacula has for this
1068 more importantly it's active. Thank you so much for that
1069 even more important, it's not flaky
1070 it has an open access catalog, opening many possibilities
1071 it's pushing toward heterogeneous systems capability
1073 Macintosh file client
1074 macs are an interesting niche, but I fear a server is a rathole
1075 working bare iron recovery for windows
1076 the option for inc/diff backups not reset on fileset revision
1077 a) use both change and inode update time against base time
1078 b) do the full catalog check (expensive but accurate)
1079 sizing guide (how much system is needed to back up N systems/files)
1080 consultants on using bacula in building a disaster recovery system
1081 an integration guide
1082 or how to get at fancy things that one could do with bacula
1083 logwatch code for bacula logs (or similar)
1084 linux distro inclusion of bacula (brings good and bad, but necessary)
1085 win2k/XP server capability (icky but you asked)
1086 support for Oracle database ??
1088 - Look at adding SQL server and Exchange support for Windows.
1089 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1090 is needed to properly specify ranges.
1091 - Add progress of files/bytes to SD and FD.
1092 - Print warning message if FileId > 4 billion
1093 - do a "messages" before the first prompt in Console
1094 - Client does not show busy during Estimate command.
1095 - Implement Console mtx commands.
1096 - Implement a Mount Command and an Unmount Command where
1097 the users could specify a system command to be performed
1098 to do the mount, after which Bacula could attempt to
1099 read the device. This is for Removeable media such as a CDROM.
1100 - Most likely, this mount command would be invoked explicitly
1101 by the user using the current Console "mount" and "unmount"
1102 commands -- the Storage Daemon would do the right thing
1103 depending on the exact nature of the device.
1104 - As with tape drives, when Bacula wanted a new removable
1105 disk mounted, it would unmount the old one, and send a message
1106 to the user, who would then use "mount" as described above
1107 once he had actually inserted the disk.
1108 - Implement dump/print label to UA
1109 - Spool to disk only when the tape is full, then when a tape is hung move
1111 - bextract is sending everything to the log file ****FIXME****
1112 - Allow multiple Storage specifications (or multiple names on
1113 a single Storage specification) in the Job record. Thus a job
1114 can be backed up to a number of storage devices.
1115 - Implement some way for the File daemon to contact the Director
1116 to start a job or pass its DHCP obtained IP number.
1117 - Implement a query tape prompt/replace feature for a console
1118 - Make sure that Bacula rechecks the tape after the 20 min wait.
1119 - Set IO_NOWAIT on Bacula TCP/IP packets.
1120 - Try doing a raw partition backup and restore by mounting a
1122 - From Lars Kellers:
1123 Yes, it would allow to highly automatic the request for new tapes. If a
1124 tape is empty, bacula reads the barcodes (native or simulated), and if
1125 an unused tape is found, it runs the label command with all the
1126 necessary parameters.
1128 By the way can bacula automatically "move" an empty/purged volume say
1129 in the "short" pool to the "long" pool if this pool runs out of volume
1131 - What to do about "list files job=xxx".
1132 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1133 file descriptor leak in Bacula.
1134 - Can we dynamically change FileSets?
1135 - If pool specified to label command and Label Format is specified,
1136 automatically generate the Volume name.
1137 - Add ExhautiveRestoreSearch
1138 - Look at the possibility of loading only the necessary
1139 data into the restore tree (i.e. do it one directory at a
1140 time as the user walks through the tree).
1141 - Possibly use the hash code if the user selects all for a restore command.
1142 - Fix "restore all" to bypass building the tree.
1143 - Prohibit backing up archive device (findlib/find_one.c:128)
1144 - Implement Release Device in the Job resource to unmount a drive.
1145 - Implement Acquire Device in the Job resource to mount a drive,
1146 be sure this works with admin jobs so that the user can get
1147 prompted to insert the correct tape. Possibly some way to say to
1148 run the job but don't save the files.
1149 - Make things like list where a file is saved case independent for
1151 - Implement a Recycle command
1152 - Start working on Base jobs.
1153 - From Phil Stracchino:
1154 It would probably be a per-client option, and would be called
1155 something like, say, "Automatically purge obsoleted jobs". What it
1156 would do is, when you successfully complete a Differential backup of a
1157 client, it would automatically purge all Incremental backups for that
1158 client that are rendered redundant by that Differential. Likewise,
1159 when a Full backup on a client completed, it would automatically purge
1160 all Differential and Incremental jobs obsoleted by that Full backup.
1161 This would let people minimize the number of tapes they're keeping on
1162 hand without having to master the art of retention times.
1163 - When doing a Backup send all attributes back to the Director, who
1164 would then figure out what files have been deleted.
1165 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1166 explicit permission to do so. It should also mark the tape in error
1167 if there is an error.
1168 - Cancel waiting for Client connect in SD if FD goes away.
1170 - Implement timeout in response() when it should come quickly.
1171 - Implement a Slot priority (loaded/not loaded).
1172 - Implement "vacation" Incremental only saves.
1173 - Implement create "FileSet"?
1174 - Add prefixlinks to where or not where absolute links to FD.
1175 - Issue message to mount a new tape before the rewind.
1176 - Simplified client job initiation for portables.
1177 - If SD cannot open a drive, make it periodically retry.
1178 - Add more of the config info to the tape label.
1180 - Refine SD waiting output:
1181 Device is being positioned
1182 > Device is being positioned for append
1183 > Device is being positioned to file x
1185 - Figure out some way to estimate output size and to avoid splitting
1186 a backup across two Volumes -- this could be useful for writing CDROMs
1187 where you really prefer not to have it split -- not serious.
1188 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1189 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1190 actual data on the Volume and compare it.
1191 - Make bcopy read through bad tape records.
1192 - Program files (i.e. execute a program to read/write files).
1193 Pass read date of last backup, size of file last time.
1194 - Add Signature type to File DB record.
1195 - CD into subdirectory when open()ing files for backup to
1196 speed up things. Test with testfind().
1197 - Priority job to go to top of list.
1198 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1199 - Implement some way for the Console to dynamically create a job.
1200 - Solaris -I on tar for include list
1201 - Need a verbose mode in restore, perhaps to bsr.
1202 - bscan without -v is too quiet -- perhaps show jobs.
1203 - Add code to reject whole blocks if not wanted on restore.
1204 - Check if we can increase Bacula FD priorty in Win2000
1205 - Check if both CatalogFiles and UseCatalog are set to SD.
1206 - Possibly add email to Watchdog if drive is unmounted too
1207 long and a job is waiting on the drive.
1208 - After unmount, if restore job started, ask to mount.
1209 - Add UA rc and history files.
1210 - put termcap (used by console) in ./configure and
1211 allow -with-termcap-dir.
1212 - Fix Autoprune for Volumes to respect need for full save.
1213 - Compare tape to Client files (attributes, or attributes and data)
1214 - Make all database Ids 64 bit.
1215 - Allow console commands to detach or run in background.
1216 - Add SD message variables to control operator wait time
1217 - Maximum Operator Wait
1218 - Minimum Message Interval
1219 - Maximum Message Interval
1220 - Send Operator message when cannot read tape label.
1221 - Verify level=Volume (scan only), level=Data (compare of data to file).
1222 Verify level=Catalog, level=InitCatalog
1224 - Add keyword search to show command in Console.
1225 - Events : tape has more than xxx bytes.
1226 - Complete code in Bacula Resources -- this will permit
1227 reading a new config file at any time.
1228 - Handle ctl-c in Console
1229 - Implement script driven addition of File daemon to config files.
1230 - Think about how to make Bacula work better with File (non-tape) archives.
1231 - Write Unix emulator for Windows.
1232 - Make database type selectable by .conf files i.e. at runtime
1233 - Set flag for uname -a. Add to Volume label.
1234 - Restore files modified after date
1235 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1236 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1237 - Timout a job or terminate if link goes down, or reopen link and query.
1238 - Concept of precious tapes (cannot be reused).
1239 - Make bcopy copy with a single tape drive.
1240 - Permit changing ownership during restore.

1254 - Autolabel should be specified by DIR instead of SD.
1256 - Add media capacity
1257 - AutoScan (check checksum of tape)
1258 - Format command = "format /dev/nst0"
1262 - Seek resolution (usually corresponds to buffer size)
1263 - EODErrorCode=ENOSPC or code
1264 - Partial Read error code
1265 - Partial write error code
1266 - Nonformatted read error
1267 - Nonformatted write error
1268 - WriteProtected error
1272 - IgnoreCloseErrors=yes
1282 - Write a Storage daemon that uses pipes and
1283 standard Unix programs to write to the tape.
1285 - Need something that monitors the JCR queue and
1286 times out jobs by asking the deamons where they are.
1287 - Enhance Jmsg code to permit buffering and saving to disk.
1288 - Verify from Volume
1289 - Need report class for messages. Perhaps
1290 report resource where report=group of messages
1291 - enhance scan_attrib and rename scan_jobtype, and
1292 fill in code for "since" option
1293 - Director needs a time after which the report status is sent
1294 anyway -- or better yet, a retry time for the job.
1295 - Don't reschedule a job if previous incarnation is still running.
1296 - Some way to automatically backup everything is needed????
1297 - Need a structure for pending actions:
1299 - termination status (part of buffered msgs?)
1301 Read, Write, Clean, Delete
1302 - Login to Bacula; Bacula users with different permissions:
1303 owner, group, user, quotas
1304 - Store info on each file system type (probably in the job header on tape.
1305 This could be the output of df; or perhaps some sort of /etc/mtab record.
1307 ========= ideas ===============
1308 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1309 To: <kern@sibbald.com>
1310 Subject: RE: [Bacula-users] future large programming jobs
1311 Date: Thu, 26 Feb 2004 11:34:54 -0600
1313 I noticed the subject thread and thought I would offer the following
1314 merely as sources of ideas, i.e. something to think about, not even as
1315 strong as a request. In my former life (before retiring) I often
1316 dealt with backups and storage management issues/products as a
1317 developer and as a consultant. I am currently migrating my personal
1318 network from amanda to bacula specifically because of the ability to
1319 cross media boundaries during storing backups.
1320 Are you familiar with the commercial product called ADSM (I think IBM
1321 now sells it under the Tivoli label)? It has a couple of interesting
1322 ideas that may apply to the following topics.
1324 1. Migration: Consider that when you need to restore a system, there
1325 may be pressure to hurry. If all the information for a single client
1326 can eventually end up on the same media (and in chronological order),
1327 the restore is facillitated by not having to search past information
1328 from other clients. ADSM has the concept of "client affinity" that
1329 may be associated with it's storage pools. It seems to me that this
1330 concept (as an optional feature) might fit in your architecture for
1333 ADSM also has the concept of defining one or more storage pools as
1334 "copy pools" (almost mirrors, but only in the sense of contents).
1335 These pools provide the ability to have duplicte data stored both
1336 onsite and offsite. The copy process can be scheduled to be handled
1337 by their storage manager during periods when there is no backup
1338 activity. Again, the migration process might be a place to consider
1339 implementing something like this.
1342 > It strikes me that it would be very nice to be able to do things
1344 > have the Job(s) backing up the machines run, and once they have all

1350 > mechanism described below would probably make it very easy.
1352 This is the goal. In the first step (before events), you simply
1354 the Migration to tape later.
1356 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1357 the database. Once a file (unique by path and metadata such as dates,
1358 size, ownership, etc.) is in a copy pool, no more copies are made. In
1359 other words, when you start ADSM, it begins like your concept of a
1360 base job. After that it is in the "incremental" mode. You can
1361 configure the number of "generations" of files to be retained, plus a
1362 retention date after which even old generations are purged. The
1363 database tracks the contents of media and projects the percentage of
1364 each volume that is valid. When the valid content of a volume drops
1365 below a configured percentage, the valid data are migrated to another
1366 volume and the old volume is marked as empty. Note, this requires
1367 ADSM to have an idea of the contents of a client, i.e. marking the
1368 database when an existing file was deleted, but this would solve your
1369 issue of restoring a client without restoring deleted files.
1371 This is pretty far from what bacula now does, but if you are going to
1372 rip things up for Base jobs,.....
1373 Also, the benefits of this are huge for very large shops, especially
1374 with media robots, but are a pain for shops with manual media
1378 > Base jobs sound pretty useful, but I'm not dying for them.
1380 Nobody is dying for them, but when you see what it does, you will die
1386 ==============================
1389 - Implement FSM (File System Modules).
1390 - Audit M_ error codes to ensure they are correct and consistent.
1391 - Add variable break characters to lex analyzer.
1392 Either a bit mask or a string of chars so that
1393 the caller can change the break characters.
1394 - Make a single T_BREAK to replace T_COMMA, etc.
1395 - Ensure that File daemon and Storage daemon can
1396 continue a save if the Director goes down (this
1397 is NOT currently the case). Must detect socket error,
1398 buffer messages for later.
1399 - Add ability to backup to two Storage devices (two SD sessions) at
1400 the same time -- e.g. onsite, offsite.
1402 ======================================================
1404 It is somewhat like a Full save becomes an incremental since
1405 the Base job (or jobs) plus other non-base files.
1407 - A Base backup is same as Full backup, just different type.
1408 - New BaseFiles table that contains:
1410 BaseJobId - Base JobId referenced for this FileId (needed ???)
1411 JobId - JobId currently running
1412 FileId - File not backed up, exists in Base Job
1413 FileIndex - FileIndex from Base Job.
1414 i.e. for each base file that exists but is not saved because
1415 it has not changed, the File daemon sends the JobId, BaseId,
1416 FileId, FileIndex back to the Director who creates the DB entry.
1417 - To initiate a Base save, the Director sends the FD
1418 the FileId, and full filename for each file in the Base.
1419 - When the FD finds a Base file, he requests the Director to
1420 send him the full File entry (stat packet plus MD5), or
1421 conversely, the FD sends it to the Director and the Director
1422 says yes or no. This can be quite rapid if the FileId is kept
1423 by the FD for each Base Filename.
1424 - It is probably better to have the comparison done by the FD
1425 despite the fact that the File entry must be sent across the
1427 - An alternative would be to send the FD the whole File entry
1428 from the start. The disadvantage is that it requires a lot of
1429 space. The advantage is that it requires less communications
1431 - The Job record must be updated to indicate that one or more
1433 - At end of Job, FD returns:
1434 1. Count of base files/bytes not written to tape (i.e. matches)
1435 2. Count of base file that were saved i.e. had changed.
1436 - No tape record would be written for a Base file that matches, in the
1437 same way that no tape record is written for Incremental jobs where
1438 the file is not saved because it is unchanged.
1439 - On a restore, all the Base file records must explicitly be
1440 found from the BaseFile tape. I.e. for each Full save that is marked
1441 to have one or more Base Jobs, search the BaseFile for all occurrences
1443 - An optimization might be to make the BaseFile have:
1449 This would avoid the need to explicitly fetch each File record for
1450 the Base job. The Base Job record will be fetched to get the
1451 VolSessionId and VolSessionTime.

1455 Preliminary design of Deletion of disk volumes
1457 tem 5: Deletion of disk Volumes when pruned
1459 Origin: Ross Boylan <RossBoylan at stanfordalumni dot org> (edited
1463 What: Provide a way for Bacula to automatically remove Volumes
1464 from the filesystem, or optionally to truncate them.
1465 Obviously, the Volume must be pruned prior removal.
1467 Why: This would allow users more control over their Volumes and
1468 prevent disk based volumes from consuming too much space.
1470 Notes: The following two directives might do the trick:
1472 Volume Data Retention = <time period>
1473 Remove Volume After = <time period>
1475 The migration project should also remove a Volume that is
1476 migrated. This might also work for tape Volumes.
1478 Notes: (Kern). The data fields to control this have been added
1479 to the new 3.0.0 database table structure.
1481 As noted above, in version 3.0.0, we added a new Media column
1482 named ActionOnPurge, which is a TINYINT (smallint in PostgreSQL).
1483 The purpose of this field is to have a flag set with each Volume
1484 that determines certain actions that will be performed when a
1485 Volume is being marked Purged (i.e. when there are no longer any
1486 Job records pointing to that Volume).
1488 We have envisioned that ActionOnPurge could take on the following
1489 values (some are exclusive and others inclusive):
1492 Delete Delete the Volume from the catalog and disk
1493 What delete means for a tape is unclear.
1494 Truncate Truncate the Volume
1495 Erase Erase the Volume (overwrite data) could be
1496 very time consuming. Erase could be specified
1497 with either Truncate or Delete.
1499 Implementation details:
1500 - ActionOnPurge is probably a bit mask.
1501 - There needs to be a new Directive in the Pool resource that allows
1502 setting of this flag.
1503 - The flag must be passed to the SD along with the current Volume information.
1504 - There needs to be a new command sent from the Director to the SD
1505 that indicates that a Purge was done, the Volume name, and that it
1507 - For security reasons the SD must very carefully check that it actually
1508 can find the correct volume. This means, it must mount it, read the label
1509 or already have done so, and verify that the Volume is really there.
1510 Then the SD can perform the requested function (delete or truncate).
1511 - Doing an Erase could be implemented later.
1512 - In the above Feature Request, the proposed Volume Data Retention
1513 directive is already implemented with Volume Retention Interval.
1514 - In the above Feature Request, the proposed Remove Volume After is
1515 a bit problematic as it means that some action must occur some time
1516 later, and currently Bacula has no mechanism to handle such events.
1517 This will probably be considered as a feature to be added later
1518 if there is sufficient demand.
1520 =========================================================
1522 Item 1: Ability to restart failed jobs
1527 What: Often jobs fail because of a communications line drop or max run time,
1528 cancel, or some other non-critical problem. Currrently any data
1529 saved is lost. This implementation should modify the Storage daemon
1530 so that it saves all the files that it knows are completely backed
1533 The jobs should then be marked as incomplete and a subsequent
1534 Incremental Accurate backup will then take into account all the
1535 previously saved job.
1537 Why: Avoids backuping data already saved.
1539 Notes: Requires Accurate to restart correctly. Must completed have a minimum
1540 volume of data or files stored on Volume before enabling.
1542 Implementation notes:
1543 - Must define new I job termination code for incomplete Jobs -- Done
1544 - In the SD must track the position of the attributes being spooled
1545 when data is actually written to the Volume -- Done
1546 - In the SD, truncate the attributes to the last valid file written
1548 - The Dir must past restart flag to SD -- Done
1549 - If restart flag is sent in SD, and Job fails, must truncate attribute
1550 file and send it to Dir marking the job as I (incomplete).
1551 - In Dir when a Job is restarted, if there is an Incomplete job, must
1552 send Accurate information to FD.
1553 - In FD must use accurate information
1554 - If Incomplete job finishes, must mark it T.
1558 Handling removable disks
1560 From: Karl Cunningham <karlc@keckec.com>
1562 My backups are only to hard disk these days, in removable bays. This is my
1563 idea of how a backup to hard disk would work more smoothly. Some of these
1564 things Bacula does already, but I mention them for completeness. If others
1565 have better ways to do this, I'd like to hear about it.
1567 1. Accommodate several disks, rotated similar to how tapes are. Identified
1568 by partition volume ID or perhaps by the name of a subdirectory.
1569 2. Abort & notify the admin if the wrong disk is in the bay.
1570 3. Write backups to different subdirectories for each machine to be backed
1572 4. Volumes (files) get created as needed in the proper subdirectory, one
1574 5. When a disk is recycled, remove or zero all old backup files. This is
1575 important as the disk being recycled may be close to full. This may be
1576 better done manually since the backup files for many machines may be
1577 scattered in many subdirectories.
1584 - Fix bpipe.c so that it does not modify results pointer.
1585 ***FIXME*** calling sequence should be changed.
