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

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
88 - Prune by Pool (Job and File)
89 - Prune by Job and or Job Level (Full, Differential, Incremental)
90 - Strict automatic pruning (runscript console command?)
91 - Why no error message if restore has no permission on the where
93 - Possibly allow manual "purge" to purge a Volume that has not
94 yet been written (even if FirstWritten time is zero) see ua_purge.c
96 - Add disk block detection bsr code (make it work).
98 - User options for plugins.
99 - Pool Storage override precedence over command line.
100 - Autolabel only if Volume catalog information indicates tape not
101 written. This will avoid overwriting a tape that gets an I/O
102 error on reading the volume label.
103 - I/O error, SD thinks it is not the right Volume, should check slot
104 then disable volume, but Asks for mount.
105 - Can be posible modify package to create and use configuration files in
110 /etc/bacula/bacula-dir.conf
111 /etc/bacula/conf.d/pools.conf
112 /etc/bacula/conf.d/clients.conf
113 /etc/bacula/conf.d/storages.conf
115 and into bacula-dir.conf file include
117 @/etc/bacula/conf.d/pools.conf
118 @/etc/bacula/conf.d/clients.conf
119 @/etc/bacula/conf.d/storages.conf
120 - Possibly add an Inconsistent state when a Volume is in error
122 - Fix #ifdefing so that smartalloc can be disabled. Check manual
123 -- the default is enabled.
124 - Change calling sequence to delete_job_id_range() in ua_cmds.c
125 the preceding strtok() is done inside the subroutine only once.
126 - Dangling softlinks are not restored properly. For example, take a
127 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
128 move the directory to another machine where the file /usr/share/autoconf does
129 not exist, back it up, then try a full restore. It fails.
130 - Softlinks that point to non-existent file are not restored in restore all,
131 but are restored if the file is individually selected. BUG!
132 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
133 Win32 to avoid patent problems.
134 - Implement multiple jobid specification for the cancel command,
135 similar to what is permitted on the update slots command.
136 - Better yet allow wild-cards or regexes.
137 - Add Group resource for grouping Jobs so they can all be
138 run at the same time or canceled at the same time.
139 - modify pruning to keep a fixed number of versions of a file,
141 - the cd-command should allow complete paths
142 i.e. cd /foo/bar/foo/bar
143 -> if a customer mails me the path to a certain file,
144 its faster to enter the specified directory
145 - Make tree walk routines like cd, ls, ... more user friendly
146 by handling spaces better.
147 - When doing a restore, if the user does an "update slots"
148 after the job started in order to add a restore volume, the
149 values prior to the update slots will be put into the catalog.
150 Must retrieve catalog record merge it then write it back at the
151 end of the restore job, if we want to do this right.
155 MA = (last_MA * 3 + rate) / 4
156 rate = (bytes - last_bytes) / (runtime - last_runtime)
157 - Add a recursive mark command (rmark) to restore.
158 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
159 of the same level and does not permit multiple simultaneous
160 running of that Job (i.e. lets any previous invocation finish
161 before doing Interval testing).
162 - Look at simplifying File exclusions.
164 - Auto update of slot:
165 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
166 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

170 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
171 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
172 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.

174 - Separate Files and Directories in catalog
175 - Create FileVersions table
176 - Look at rsysnc for incremental updates and dedupping
177 - Add MD5 or SHA1 check in SD for data validation
178 - finish implementation of fdcalled -- see ua_run.c:105
179 - Fix problem in postgresql.c in my_postgresql_query, where the
180 generation of the error message doesn't differentiate result==NULL
181 and a bad status from that result. Not only that, the result is
182 cleared on a bail_out without having generated the error message.
184 - Implement SDErrors (must return from SD)
185 - Implement USB keyboard support in rescue CD.
186 - Implement continue spooling while despooling.
187 - Remove all install temp files in Win32 PLUGINSDIR.
188 - Audit retention periods to make sure everything is 64 bit.
189 - No where in restore causes kaboom.
190 - Performance: multiple spool files for a single job.
191 - Performance: despool attributes when despooling data (problem
192 multiplexing Dir connection).
193 - Make restore use the in-use volume reservation algorithm.
194 - When Pool specifies Storage command override does not work.
195 - Implement wait_for_sysop() message display in wait_for_device(), which
196 now prints warnings too often.
197 - Ensure that each device in an Autochanger has a different
199 - Look at sg_logs -a /dev/sg0 for getting soft errors.
200 - btape "test" command with Offline on Unmount = yes
202 This test is essential to Bacula.
204 I'm going to write one record in file 0,
205 two records in file 1,
206 and three records in file 2
208 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715

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

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

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

631 block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
632 Error writing final EOF to tape. This tape may not be readable.
633 dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
634 askdir.c:219 NULL Volume name. This shouldn't happen!!!
635 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
636 Label command failed for Volume DLT-20Dec04.
637 Do not forget to mount the drive!!!
638 - Bug: if a job is manually scheduled to run later, it does not appear
639 in any status report and cannot be cancelled.
644 How about introducing a Type = MgmtPolicy job type? That job type would
645 be responsible for scanning the Bacula environment looking for specific
646 conditions, and submitting the appropriate jobs for implementing said
650 Name = "Migration-Policy"
652 Policy Selection Job Type = Migrate
653 Scope = "<keyword> <operator> <regexp>"
654 Threshold = "<keyword> <operator> <regexp>"
655 Job Template = <template-name>
658 Where <keyword> is any legal job keyword, <operator> is a comparison
659 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
660 appropriate regexp. I could see an argument for Scope and Threshold
661 being SQL queries if we want to support full flexibility. The
662 Migration-Policy job would then get scheduled as frequently as a site
663 felt necessary (suggested default: every 15 minutes).
668 Name = "Migration-Policy"
670 Policy Selection Job Type = Migration
672 Threshold = "Migration Selection Type = LowestUtil"
673 Job Template = "MigrationTemplate"
676 would select all pools for examination and generate a job based on
677 MigrationTemplate to automatically select the volume with the lowest
678 usage and migrate it's contents to the nextpool defined for that pool.
680 This policy abstraction would be really handy for adjusting the behavior
681 of Bacula according to site-selectable criteria (one thing that pops
682 into mind is Amanda's ability to automatically adjust backup levels
683 depending on various criteria).
689 - Add Pool/Storage override regression test.
690 - Add delete JobId to regression.
691 - Add a regression test for dbcheck.
692 - New test to add bscan to four-concurrent-jobs regression,
693 i.e. after the four-concurrent jobs zap the
694 database as is done in the bscan-test, then use bscan to
695 restore the database, do a restore and compare with the
697 - Add restore of specific JobId to regression (item 3
698 on the restore prompt)
699 - Add IPv6 to regression
700 - Add database test to regression. Test each function like delete,
703 - AntiVir can slow down backups on Win32 systems.
704 - Win32 systems with FAT32 can be much slower than NTFS for
705 more than 1000 files per directory.
709 - A HOLD command to stop all jobs from starting.
710 - A PAUSE command to pause all running jobs ==> release the
712 - Media Type = LTO,LTO-2,LTO-3
713 Media Type Read = LTO,LTO2,LTO3
714 Media Type Write = LTO2, LTO3
716 === From Carsten Menke <bootsy52@gmx.net>
718 Following is a list of what I think in the situations where I'm faced with,
719 could be a usefull enhancement to bacula, which I'm certain other users will
720 benefit from as well.
722 1. NextJob/NextJobs Directive within a Job Resource in the form of
723 NextJobs = job1,job2.
726 I currently solved the problem with running multiple jobs each after each
727 by setting the Max Wait Time for a job to 8 hours, and give
728 the jobs different Priorities. However, there scenarios where
729 1 Job is directly depending on another job, so if the former job fails,
730 the job after it needn't to be run
731 while maybe other jobs should run despite of that
734 A Backup Job and a Verify job, if the backup job fails there is no need to run
735 the verify job, as the backup job already failed. However, one may like
736 to backup the Catalog to disk despite of that the main backup job failed.
739 I see that this is related to the Event Handlers which are on the ToDo
740 list, also it is maybe a good idea to check for the return value and
741 execute different actions based on the return value
744 3. offline capability to bconsole
747 Currently I use a script which I execute within the last Job via the
748 RunAfterJob Directive, to release and eject the tape.
749 So I have to call bconsole "release=Storage-Name" and afterwards
750 mt -f /dev/nst0 eject to get the tape out.
752 If I have multiple Storage Devices, than these may not be /dev/nst0 and
753 I have to modify the script or call it with parameters etc.
754 This would actually not be needed, as everything is already defined
755 in bacula-sd.conf and if I can invoke bconsole with the
756 storage name via $1 in the script than I'm done and information is
759 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
763 For the reason mentioned in 3. to have the ability to call a
764 script with /scripts/foobar %s and in the script use $1
765 to pass the Storage Name to bconsole
767 5. Setting Volume State within a Job Resource
770 Instead of using "Maximum Volume Jobs" in the Pool Resource,
771 I would have the possibilty to define
772 in a Job Resource that after this certain job is run, the Volume State
773 should be set to "Volume State = Used", this give more flexibility (IMHO).
775 6. Localization of Bacula Messages
778 Unfortunatley many,many people I work with don't speak english very well.
779 So if at least the Reporting messages would be localized then they
780 would understand that they have to change the tape,etc. etc.
782 I volunteer to do the german translations, and if I can convince my wife also
783 french and Morre (western african language).
785 7. OK, this is evil, probably bound to security risks and maybe not possible
786 due to the design of bacula.
788 Implementation of Backtics ( `command` ) for shell comand execution to
789 the "Label Format" Directive.
793 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
794 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
795 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
796 the localized name for the day of the week appended to the
797 format string. Then I have the tape labeled automatically with weekday
798 name in the correct language.
800 - Make output from status use html table tags for nicely
801 presenting in a browser.
802 - Browse generations of files.
803 - I've seen an error when my catalog's File table fills up. I
804 then have to recreate the File table with a larger maximum row
805 size. Relevant information is at
806 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
807 "Installing and Configuring MySQL" chapter should talk a bit
808 about this potential problem, and recommend a solution.
809 - For Solaris must use POSIX awk.
810 - Want speed of writing to tape while despooling.
811 - Supported autochanger:
819 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
820 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
821 - Add regex from http://www.pcre.org to Bacula for Win32.
822 - Use only shell tools no make in CDROM package.
823 - Include within include does it work?
824 - Implement a Pool of type Cleaning?
825 - Implement VolReadTime and VolWriteTime in SD
826 - Modify Backing up Your Database to include a bootstrap file.
827 - Think about making certain database errors fatal.
828 - Look at correcting the time jump in the scheduler for daylight
829 savings time changes.
830 - Add a "real" timer to network connections.
831 - Promote to Full = Time period
832 - Check dates entered by user for correctness (month/day/... ranges)
833 - Compress restore Volume listing by date and first file.
834 - Look at patches/bacula_db.b2z postgresql that loops during restore.
836 - Perhaps add read/write programs and/or plugins to FileSets.
837 - How to handle backing up portables ...
838 - Add some sort of guaranteed Interval for upgrading jobs.
839 - Can we write the state file after every job terminates? On Win32
840 the system crashes and the state file is not updated.
843 Documentation to do: (any release a little bit at a time)
844 - Doc to do unmount before removing magazine.
845 - Alternative to static linking "ldd prog" save all binaries listed,
846 restore them and point LD_LIBRARY_PATH to them.
847 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
848 - Document query file format.
849 - Add more documentation for bsr files.
850 - Document problems with Verify and pruning.
851 - Document how to use multiple databases.
852 - VXA drives have a "cleaning required"
853 indicator, but Exabyte recommends preventive cleaning after every 75
856 In this context, it should be noted that Exabyte has a command-line
857 vxatool utility available for free download. (The current version is
858 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
859 test the drive, unload tapes, change drive settings, flash new firmware,
861 Of particular interest in this context is that vxatool <device> -i will
862 report, among other details, the time since last cleaning in tape motion
863 minutes. This information can be retrieved (and settings changed, for
864 that matter) through the generic-SCSI device even when Bacula has the
865 regular tape device locked. (Needless to say, I don't recommend
866 changing tape settings while a job is running.)
867 - Lookup HP cleaning recommendations.
868 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
869 - Document doing table repair
872 ===================================
873 - Add macro expansions in JobDefs.
874 Run Before Job = "SomeFile %{Level} %{Client}"
875 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
876 - Use non-blocking network I/O but if no data is available, use
878 - Use gather write() for network I/O.
879 - Autorestart on crash.
880 - Add bandwidth limiting.
881 - When an error in input occurs and conio beeps, you can back
882 up through the prompt.
883 - Detect fixed tape block mode during positioning by looking at
884 block numbers in btape "test". Possibly adjust in Bacula.
885 - Fix list volumes to output volume retention in some other
886 units, perhaps via a directive.
887 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
888 with multiple priorities.
889 - If you use restore replace=never, the directory attributes for
890 non-existent directories will not be restored properly.
892 - see lzma401.zip in others directory for new compression
894 - Allow the user to select JobType for manual pruning/purging.
895 - bscan does not put first of two volumes back with all info in
897 - Figure out how to make named console messages go only to that
898 console and to the non-restricted console (new console class?).
899 - Make restricted console prompt for password if *ask* is set or
900 perhaps if password is undefined.
901 - Implement "from ISO-date/time every x hours/days/weeks/months" in
904 ==== from Marc Schoechlin
905 - the help-command should be more verbose
906 (it should explain the paramters of the different
908 -> its time-comsuming to consult the manual anytime
909 you need a special parameter
910 -> maybe its more easy to maintain this, if the
911 descriptions of that commands are outsourced to
913 - if the password is not configured in bconsole.conf
914 you should be asked for it.
915 -> sometimes you like to do restore on a customer-machine
916 which shouldnt know the password for bacula.
917 -> adding the password to the file favours admins
918 to forget to remove the password after usage
920 the protection of that file is less important
921 - long-listed-output of commands should be scrollable
922 like the unix more/less-command does
923 -> if someone runs 200 and more machines, the lists could
924 be a little long and complex
925 - command-output should be shown column by column
926 to reduce scrolling and to increase clarity
928 - lsmark should list the selected files with full
930 - wildcards for selecting and file and directories would be nice
931 - any actions should be interuptable with STRG+C
932 - command-expansion would be pretty cool
934 - When the replace Never option is set, new directory permissions
935 are not restored. See bug 213. To fix this requires creating a
936 list of newly restored directories so that those directory
937 permissions *can* be restored.
938 - Add prune all command
939 - Document fact that purge can destroy a part of a restore by purging
940 one volume while others remain valid -- perhaps mark Jobs.
941 - Add multiple-media-types.txt
942 - look at mxt-changer.html
943 - Make ? do a help command (no return needed).
944 - Implement restore directory.
945 - Document streams and how to implement them.
946 - Try not to re-backup a file if a new hard link is added.
947 - Add feature to backup hard links only, but not the data.
948 - Fix stream handling to be simpler.
949 - Add Priority and Bootstrap to Run a Job.
950 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
952 - Remove View FileSet button from Run a Job dialog.
953 - Handle prompt for restore job at end of Restore command.
954 - Add display of total selected files to Restore window.
955 - Add tree pane to left of window.
956 - Add progress meter.
957 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
958 - Add message to user to check for fixed block size when the forward
959 space test fails in btape.
960 - When unmarking a directory check if all files below are unmarked and
961 then remove the + flag -- in the restore tree.
962 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
963 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
964 - Revisit the question of multiple Volumes (disk) on a single device.
965 - Add a block copy option to bcopy.
966 - Fix "llist jobid=xx" where no fileset or client exists.
967 - For each job type (Admin, Restore, ...) require only the really necessary
968 fields.- Pass Director resource name as an option to the Console.
969 - Add a "batch" mode to the Console (no unsolicited queries, ...).
970 - Allow browsing the catalog to see all versions of a file (with
971 stat data on each file).
972 - Restore attributes of directory if replace=never set but directory
974 - Use SHA1 on authentication if possible.
975 - See comtest-xxx.zip for Windows code to talk to USB.
976 - Add John's appended files:
977 Appended = { /files/server/logs/http/*log }
978 and such files would be treated as follows.On a FULL backup, they would
979 be backed up like any other file.On an INCREMENTAL backup, where a
980 previous INCREMENTAL or FULL was already in thecatalogue and the length
981 of the file wasgreater than the length of the last backup, only thedata
982 added since the last backup will be dumped.On an INCREMENTAL backup, if
983 the length of the file is less than thelength of the file with the same
984 name last backed up, the completefile is dumped.On Windows systems, with
985 creation date of files, we can be evensmarter about this and not count
986 entirely upon the length.On a restore, the full and all incrementals
987 since it will beapplied in sequence to restore the file.
988 - Check new HAVE_WIN32 open bits.
989 - Check if the tape has moved before writing.
990 - Handling removable disks -- see below:
991 - Add FromClient and ToClient keywords on restore command (or
992 BackupClient RestoreClient).
993 - Implement a JobSet, which groups any number of jobs. If the
994 JobSet is started, all the jobs are started together.
995 Allow Pool, Level, and Schedule overrides.
996 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
997 correctly for multiple simultaneous jobs.
998 - Implement the Media record flag that indicates that the Volume does disk
1000 - Implement VolAddr, which is used when Volume is addressed like a disk,
1001 and form it from VolFile and VolBlock.
1002 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1003 pointer (rec) to try_repositioning().
1004 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1005 which would take precidence over the Catalog "JobRetention".
1006 - Implement Label Format in Add and Label console commands.
1007 - Put email tape request delays on one or more variables. User wants
1008 to cancel the job after a certain time interval. Maximum Mount Wait?
1009 - Job, Client, Device, Pool, or Volume?
1010 Is it possible to make this a directive which is *optional* in multiple
1011 resources, like Level? If so, I think I'd make it an optional directive
1012 in Job, Client, and Pool, with precedence such that Job overrides Client
1013 which in turn overrides Pool.
1015 - New Storage specifications:
1016 - Want to write to multiple storage devices simultaneously
1017 - Want to write to multiple storage devices sequentially (in one job)
1018 - Want to read/write simultaneously
1019 - Key is MediaType -- it must match
1021 Passed to SD as a sort of BSR record called Storage Specification
1025 MediaType -> Next MediaType
1027 Device -> Next Device
1029 Allow multiple Storage specifications
1037 Allow Multiple Pool specifications (note, Pool currently
1039 Allow Multiple MediaType specifications in Dir conf
1040 Allow Multiple Device specifications in Dir conf
1041 Perhaps keep this in a single SSR
1042 Tie a Volume to a specific device by using a MediaType that
1043 is contained in only one device.
1044 In SD allow Device to have Multiple MediaTypes
1046 - Ideas from Jerry Scharf:
1047 First let's point out some big pluses that bacula has for this
1049 more importantly it's active. Thank you so much for that
1050 even more important, it's not flaky
1051 it has an open access catalog, opening many possibilities
1052 it's pushing toward heterogeneous systems capability
1054 Macintosh file client
1055 macs are an interesting niche, but I fear a server is a rathole
1056 working bare iron recovery for windows
1057 the option for inc/diff backups not reset on fileset revision
1058 a) use both change and inode update time against base time
1059 b) do the full catalog check (expensive but accurate)
1060 sizing guide (how much system is needed to back up N systems/files)
1061 consultants on using bacula in building a disaster recovery system
1062 an integration guide
1063 or how to get at fancy things that one could do with bacula
1064 logwatch code for bacula logs (or similar)
1065 linux distro inclusion of bacula (brings good and bad, but necessary)
1066 win2k/XP server capability (icky but you asked)
1067 support for Oracle database ??
1069 - Look at adding SQL server and Exchange support for Windows.
1070 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1071 is needed to properly specify ranges.
1072 - Add progress of files/bytes to SD and FD.
1073 - Print warning message if FileId > 4 billion
1074 - do a "messages" before the first prompt in Console
1075 - Client does not show busy during Estimate command.
1076 - Implement Console mtx commands.
1077 - Implement a Mount Command and an Unmount Command where
1078 the users could specify a system command to be performed
1079 to do the mount, after which Bacula could attempt to
1080 read the device. This is for Removeable media such as a CDROM.
1081 - Most likely, this mount command would be invoked explicitly
1082 by the user using the current Console "mount" and "unmount"
1083 commands -- the Storage Daemon would do the right thing
1084 depending on the exact nature of the device.
1085 - As with tape drives, when Bacula wanted a new removable
1086 disk mounted, it would unmount the old one, and send a message
1087 to the user, who would then use "mount" as described above
1088 once he had actually inserted the disk.
1089 - Implement dump/print label to UA
1090 - Spool to disk only when the tape is full, then when a tape is hung move
1092 - bextract is sending everything to the log file ****FIXME****
1093 - Allow multiple Storage specifications (or multiple names on
1094 a single Storage specification) in the Job record. Thus a job
1095 can be backed up to a number of storage devices.
1096 - Implement some way for the File daemon to contact the Director
1097 to start a job or pass its DHCP obtained IP number.
1098 - Implement a query tape prompt/replace feature for a console
1099 - Make sure that Bacula rechecks the tape after the 20 min wait.
1100 - Set IO_NOWAIT on Bacula TCP/IP packets.
1101 - Try doing a raw partition backup and restore by mounting a
1103 - From Lars Kellers:
1104 Yes, it would allow to highly automatic the request for new tapes. If a
1105 tape is empty, bacula reads the barcodes (native or simulated), and if
1106 an unused tape is found, it runs the label command with all the
1107 necessary parameters.
1109 By the way can bacula automatically "move" an empty/purged volume say
1110 in the "short" pool to the "long" pool if this pool runs out of volume
1112 - What to do about "list files job=xxx".
1113 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1114 file descriptor leak in Bacula.
1115 - Can we dynamically change FileSets?
1116 - If pool specified to label command and Label Format is specified,
1117 automatically generate the Volume name.
1118 - Add ExhautiveRestoreSearch
1119 - Look at the possibility of loading only the necessary
1120 data into the restore tree (i.e. do it one directory at a
1121 time as the user walks through the tree).
1122 - Possibly use the hash code if the user selects all for a restore command.
1123 - Fix "restore all" to bypass building the tree.
1124 - Prohibit backing up archive device (findlib/find_one.c:128)
1125 - Implement Release Device in the Job resource to unmount a drive.
1126 - Implement Acquire Device in the Job resource to mount a drive,
1127 be sure this works with admin jobs so that the user can get
1128 prompted to insert the correct tape. Possibly some way to say to
1129 run the job but don't save the files.
1130 - Make things like list where a file is saved case independent for
1132 - Implement a Recycle command
1133 - Start working on Base jobs.
1134 - From Phil Stracchino:
1135 It would probably be a per-client option, and would be called
1136 something like, say, "Automatically purge obsoleted jobs". What it
1137 would do is, when you successfully complete a Differential backup of a
1138 client, it would automatically purge all Incremental backups for that
1139 client that are rendered redundant by that Differential. Likewise,
1140 when a Full backup on a client completed, it would automatically purge
1141 all Differential and Incremental jobs obsoleted by that Full backup.
1142 This would let people minimize the number of tapes they're keeping on
1143 hand without having to master the art of retention times.
1144 - When doing a Backup send all attributes back to the Director, who
1145 would then figure out what files have been deleted.
1146 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1147 explicit permission to do so. It should also mark the tape in error
1148 if there is an error.
1149 - Cancel waiting for Client connect in SD if FD goes away.
1151 - Implement timeout in response() when it should come quickly.
1152 - Implement a Slot priority (loaded/not loaded).
1153 - Implement "vacation" Incremental only saves.
1154 - Implement create "FileSet"?
1155 - Add prefixlinks to where or not where absolute links to FD.
1156 - Issue message to mount a new tape before the rewind.
1157 - Simplified client job initiation for portables.
1158 - If SD cannot open a drive, make it periodically retry.
1159 - Add more of the config info to the tape label.
1161 - Refine SD waiting output:
1162 Device is being positioned
1163 > Device is being positioned for append
1164 > Device is being positioned to file x
1166 - Figure out some way to estimate output size and to avoid splitting
1167 a backup across two Volumes -- this could be useful for writing CDROMs
1168 where you really prefer not to have it split -- not serious.
1169 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1170 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1171 actual data on the Volume and compare it.
1172 - Make bcopy read through bad tape records.
1173 - Program files (i.e. execute a program to read/write files).
1174 Pass read date of last backup, size of file last time.
1175 - Add Signature type to File DB record.
1176 - CD into subdirectory when open()ing files for backup to
1177 speed up things. Test with testfind().
1178 - Priority job to go to top of list.
1179 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1180 - Implement some way for the Console to dynamically create a job.
1181 - Solaris -I on tar for include list
1182 - Need a verbose mode in restore, perhaps to bsr.
1183 - bscan without -v is too quiet -- perhaps show jobs.
1184 - Add code to reject whole blocks if not wanted on restore.
1185 - Check if we can increase Bacula FD priorty in Win2000
1186 - Check if both CatalogFiles and UseCatalog are set to SD.
1187 - Possibly add email to Watchdog if drive is unmounted too
1188 long and a job is waiting on the drive.
1189 - After unmount, if restore job started, ask to mount.
1190 - Add UA rc and history files.
1191 - put termcap (used by console) in ./configure and
1192 allow -with-termcap-dir.
1193 - Fix Autoprune for Volumes to respect need for full save.
1194 - Compare tape to Client files (attributes, or attributes and data)
1195 - Make all database Ids 64 bit.
1196 - Allow console commands to detach or run in background.
1197 - Add SD message variables to control operator wait time
1198 - Maximum Operator Wait
1199 - Minimum Message Interval
1200 - Maximum Message Interval
1201 - Send Operator message when cannot read tape label.
1202 - Verify level=Volume (scan only), level=Data (compare of data to file).
1203 Verify level=Catalog, level=InitCatalog
1205 - Add keyword search to show command in Console.
1206 - Events : tape has more than xxx bytes.
1207 - Complete code in Bacula Resources -- this will permit
1208 reading a new config file at any time.
1209 - Handle ctl-c in Console
1210 - Implement script driven addition of File daemon to config files.
1211 - Think about how to make Bacula work better with File (non-tape) archives.
1212 - Write Unix emulator for Windows.
1213 - Make database type selectable by .conf files i.e. at runtime
1214 - Set flag for uname -a. Add to Volume label.
1215 - Restore files modified after date
1216 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1217 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1218 - Timout a job or terminate if link goes down, or reopen link and query.
1219 - Concept of precious tapes (cannot be reused).
1220 - Make bcopy copy with a single tape drive.
1221 - Permit changing ownership during restore.

1235 - Autolabel should be specified by DIR instead of SD.
1237 - Add media capacity
1238 - AutoScan (check checksum of tape)
1239 - Format command = "format /dev/nst0"
1243 - Seek resolution (usually corresponds to buffer size)
1244 - EODErrorCode=ENOSPC or code
1245 - Partial Read error code
1246 - Partial write error code
1247 - Nonformatted read error
1248 - Nonformatted write error
1249 - WriteProtected error
1253 - IgnoreCloseErrors=yes
1263 - Write a Storage daemon that uses pipes and
1264 standard Unix programs to write to the tape.
1266 - Need something that monitors the JCR queue and
1267 times out jobs by asking the deamons where they are.
1268 - Enhance Jmsg code to permit buffering and saving to disk.
1269 - Verify from Volume
1270 - Need report class for messages. Perhaps
1271 report resource where report=group of messages
1272 - enhance scan_attrib and rename scan_jobtype, and
1273 fill in code for "since" option
1274 - Director needs a time after which the report status is sent
1275 anyway -- or better yet, a retry time for the job.
1276 - Don't reschedule a job if previous incarnation is still running.
1277 - Some way to automatically backup everything is needed????
1278 - Need a structure for pending actions:
1280 - termination status (part of buffered msgs?)
1282 Read, Write, Clean, Delete
1283 - Login to Bacula; Bacula users with different permissions:
1284 owner, group, user, quotas
1285 - Store info on each file system type (probably in the job header on tape.
1286 This could be the output of df; or perhaps some sort of /etc/mtab record.
1288 ========= ideas ===============
1289 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1290 To: <kern@sibbald.com>
1291 Subject: RE: [Bacula-users] future large programming jobs
1292 Date: Thu, 26 Feb 2004 11:34:54 -0600
1294 I noticed the subject thread and thought I would offer the following
1295 merely as sources of ideas, i.e. something to think about, not even as
1296 strong as a request. In my former life (before retiring) I often
1297 dealt with backups and storage management issues/products as a
1298 developer and as a consultant. I am currently migrating my personal
1299 network from amanda to bacula specifically because of the ability to
1300 cross media boundaries during storing backups.
1301 Are you familiar with the commercial product called ADSM (I think IBM
1302 now sells it under the Tivoli label)? It has a couple of interesting
1303 ideas that may apply to the following topics.
1305 1. Migration: Consider that when you need to restore a system, there
1306 may be pressure to hurry. If all the information for a single client
1307 can eventually end up on the same media (and in chronological order),
1308 the restore is facillitated by not having to search past information
1309 from other clients. ADSM has the concept of "client affinity" that
1310 may be associated with it's storage pools. It seems to me that this
1311 concept (as an optional feature) might fit in your architecture for
1314 ADSM also has the concept of defining one or more storage pools as
1315 "copy pools" (almost mirrors, but only in the sense of contents).
1316 These pools provide the ability to have duplicte data stored both
1317 onsite and offsite. The copy process can be scheduled to be handled
1318 by their storage manager during periods when there is no backup
1319 activity. Again, the migration process might be a place to consider
1320 implementing something like this.
1323 > It strikes me that it would be very nice to be able to do things
1325 > have the Job(s) backing up the machines run, and once they have all

1331 > mechanism described below would probably make it very easy.
1333 This is the goal. In the first step (before events), you simply
1335 the Migration to tape later.
1337 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1338 the database. Once a file (unique by path and metadata such as dates,
1339 size, ownership, etc.) is in a copy pool, no more copies are made. In
1340 other words, when you start ADSM, it begins like your concept of a
1341 base job. After that it is in the "incremental" mode. You can
1342 configure the number of "generations" of files to be retained, plus a
1343 retention date after which even old generations are purged. The
1344 database tracks the contents of media and projects the percentage of
1345 each volume that is valid. When the valid content of a volume drops
1346 below a configured percentage, the valid data are migrated to another
1347 volume and the old volume is marked as empty. Note, this requires
1348 ADSM to have an idea of the contents of a client, i.e. marking the
1349 database when an existing file was deleted, but this would solve your
1350 issue of restoring a client without restoring deleted files.
1352 This is pretty far from what bacula now does, but if you are going to
1353 rip things up for Base jobs,.....
1354 Also, the benefits of this are huge for very large shops, especially
1355 with media robots, but are a pain for shops with manual media
1359 > Base jobs sound pretty useful, but I'm not dying for them.
1361 Nobody is dying for them, but when you see what it does, you will die
1367 ==============================
1370 - Implement FSM (File System Modules).
1371 - Audit M_ error codes to ensure they are correct and consistent.
1372 - Add variable break characters to lex analyzer.
1373 Either a bit mask or a string of chars so that
1374 the caller can change the break characters.
1375 - Make a single T_BREAK to replace T_COMMA, etc.
1376 - Ensure that File daemon and Storage daemon can
1377 continue a save if the Director goes down (this
1378 is NOT currently the case). Must detect socket error,
1379 buffer messages for later.
1380 - Add ability to backup to two Storage devices (two SD sessions) at
1381 the same time -- e.g. onsite, offsite.
1383 ======================================================
1385 It is somewhat like a Full save becomes an incremental since
1386 the Base job (or jobs) plus other non-base files.
1388 - A Base backup is same as Full backup, just different type.
1389 - New BaseFiles table that contains:
1391 BaseJobId - Base JobId referenced for this FileId (needed ???)
1392 JobId - JobId currently running
1393 FileId - File not backed up, exists in Base Job
1394 FileIndex - FileIndex from Base Job.
1395 i.e. for each base file that exists but is not saved because
1396 it has not changed, the File daemon sends the JobId, BaseId,
1397 FileId, FileIndex back to the Director who creates the DB entry.
1398 - To initiate a Base save, the Director sends the FD
1399 the FileId, and full filename for each file in the Base.
1400 - When the FD finds a Base file, he requests the Director to
1401 send him the full File entry (stat packet plus MD5), or
1402 conversely, the FD sends it to the Director and the Director
1403 says yes or no. This can be quite rapid if the FileId is kept
1404 by the FD for each Base Filename.
1405 - It is probably better to have the comparison done by the FD
1406 despite the fact that the File entry must be sent across the
1408 - An alternative would be to send the FD the whole File entry
1409 from the start. The disadvantage is that it requires a lot of
1410 space. The advantage is that it requires less communications
1412 - The Job record must be updated to indicate that one or more
1414 - At end of Job, FD returns:
1415 1. Count of base files/bytes not written to tape (i.e. matches)
1416 2. Count of base file that were saved i.e. had changed.
1417 - No tape record would be written for a Base file that matches, in the
1418 same way that no tape record is written for Incremental jobs where
1419 the file is not saved because it is unchanged.
1420 - On a restore, all the Base file records must explicitly be
1421 found from the BaseFile tape. I.e. for each Full save that is marked
1422 to have one or more Base Jobs, search the BaseFile for all occurrences
1424 - An optimization might be to make the BaseFile have:
1430 This would avoid the need to explicitly fetch each File record for
1431 the Base job. The Base Job record will be fetched to get the
1432 VolSessionId and VolSessionTime.

1436 Preliminary design of Deletion of disk volumes
1438 tem 5: Deletion of disk Volumes when pruned
1440 Origin: Ross Boylan <RossBoylan at stanfordalumni dot org> (edited
1444 What: Provide a way for Bacula to automatically remove Volumes
1445 from the filesystem, or optionally to truncate them.
1446 Obviously, the Volume must be pruned prior removal.
1448 Why: This would allow users more control over their Volumes and
1449 prevent disk based volumes from consuming too much space.
1451 Notes: The following two directives might do the trick:
1453 Volume Data Retention = <time period>
1454 Remove Volume After = <time period>
1456 The migration project should also remove a Volume that is
1457 migrated. This might also work for tape Volumes.
1459 Notes: (Kern). The data fields to control this have been added
1460 to the new 3.0.0 database table structure.
1462 As noted above, in version 3.0.0, we added a new Media column
1463 named ActionOnPurge, which is a TINYINT (smallint in PostgreSQL).
1464 The purpose of this field is to have a flag set with each Volume
1465 that determines certain actions that will be performed when a
1466 Volume is being marked Purged (i.e. when there are no longer any
1467 Job records pointing to that Volume).
1469 We have envisioned that ActionOnPurge could take on the following
1470 values (some are exclusive and others inclusive):
1473 Delete Delete the Volume from the catalog and disk
1474 What delete means for a tape is unclear.
1475 Truncate Truncate the Volume
1476 Erase Erase the Volume (overwrite data) could be
1477 very time consuming. Erase could be specified
1478 with either Truncate or Delete.
1480 Implementation details:
1481 - ActionOnPurge is probably a bit mask.
1482 - There needs to be a new Directive in the Pool resource that allows
1483 setting of this flag.
1484 - The flag must be passed to the SD along with the current Volume information.
1485 - There needs to be a new command sent from the Director to the SD
1486 that indicates that a Purge was done, the Volume name, and that it
1488 - For security reasons the SD must very carefully check that it actually
1489 can find the correct volume. This means, it must mount it, read the label
1490 or already have done so, and verify that the Volume is really there.
1491 Then the SD can perform the requested function (delete or truncate).
1492 - Doing an Erase could be implemented later.
1493 - In the above Feature Request, the proposed Volume Data Retention
1494 directive is already implemented with Volume Retention Interval.
1495 - In the above Feature Request, the proposed Remove Volume After is
1496 a bit problematic as it means that some action must occur some time
1497 later, and currently Bacula has no mechanism to handle such events.
1498 This will probably be considered as a feature to be added later
1499 if there is sufficient demand.
1501 =========================================================
1503 Item 1: Ability to restart failed jobs
1508 What: Often jobs fail because of a communications line drop or max run time,
1509 cancel, or some other non-critical problem. Currrently any data
1510 saved is lost. This implementation should modify the Storage daemon
1511 so that it saves all the files that it knows are completely backed
1514 The jobs should then be marked as incomplete and a subsequent
1515 Incremental Accurate backup will then take into account all the
1516 previously saved job.
1518 Why: Avoids backuping data already saved.
1520 Notes: Requires Accurate to restart correctly. Must completed have a minimum
1521 volume of data or files stored on Volume before enabling.
1523 Implementation notes:
1524 - Must define new I job termination code for incomplete Jobs -- Done
1525 - In the SD must track the position of the attributes being spooled
1526 when data is actually written to the Volume -- Done
1527 - In the SD, truncate the attributes to the last valid file written
1529 - The Dir must past restart flag to SD -- Done
1530 - If restart flag is sent in SD, and Job fails, must truncate attribute
1531 file and send it to Dir marking the job as I (incomplete).
1532 - In Dir when a Job is restarted, if there is an Incomplete job, must
1533 send Accurate information to FD.
1534 - In FD must use accurate information
1535 - If Incomplete job finishes, must mark it T.
1539 Handling removable disks
1541 From: Karl Cunningham <karlc@keckec.com>
1543 My backups are only to hard disk these days, in removable bays. This is my
1544 idea of how a backup to hard disk would work more smoothly. Some of these
1545 things Bacula does already, but I mention them for completeness. If others
1546 have better ways to do this, I'd like to hear about it.
1548 1. Accommodate several disks, rotated similar to how tapes are. Identified
1549 by partition volume ID or perhaps by the name of a subdirectory.
1550 2. Abort & notify the admin if the wrong disk is in the bay.
1551 3. Write backups to different subdirectories for each machine to be backed
1553 4. Volumes (files) get created as needed in the proper subdirectory, one
1555 5. When a disk is recycled, remove or zero all old backup files. This is
1556 important as the disk being recycled may be close to full. This may be
1557 better done manually since the backup files for many machines may be
1558 scattered in many subdirectories.
1565 - Fix bpipe.c so that it does not modify results pointer.
1566 ***FIXME*** calling sequence should be changed.
1568 - When reserving a device to read, check to see if the Volume
1569 is already in use, if so wait. Probably will need to pass the
1570 Volume. See bug #1313. Create a regression test to simulate
1571 this problem and see if VolumePollInterval fixes it. Possibly turn
1574 - Fix restore of acls and extended attributes to count ERROR
1575 messages and make errors non-fatal.
1576 - Put save/restore various platform acl/xattrs on a pointer to simplify
1578 - Add blast attributes to DIR to SD.
1579 - Detect deadlocks in reservations.
1581 - Add list during dump
1582 - Add in plugin code flag
1583 - Add bRC_EndJob -- stops more calls to plugin this job
1584 - Add bRC_Term (unload plugin)
1585 - remove time_t from Jmsg and use utime_t?
1586 - Deadlock detection, watchdog sees if counter advances when jobs are
1587 running. With debug on, can do a "status" command.
1588 - New directive "Delete purged Volumes"
1589 - Implement unmount of USB volumes.
