16 working drive (e.g. c:\), which will lead to a problem during
17 the next job (create bootstrap file will fail). Here is the

88 - Re-check new dcr->reserved_volume
89 - Softlinks that point to non-existent file are not restored in restore all,
90 but are restored if the file is individually selected. BUG!
92 - New directive "Delete purged Volumes"
94 - Prune by Job Level (Full, Differential, Incremental)
95 - Strict automatic pruning
96 - Implement unmount of USB volumes.
97 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
98 Win32 to avoid patent problems.
99 - Implement Bacula plugins -- design API
100 - modify pruning to keep a fixed number of versions of a file,
102 - the cd-command should allow complete paths
103 i.e. cd /foo/bar/foo/bar
104 -> if a customer mails me the path to a certain file,
105 its faster to enter the specified directory
106 - Fix bpipe.c so that it does not modify results pointer.
107 ***FIXME*** calling sequence should be changed.
108 - Make tree walk routines like cd, ls, ... more user friendly
109 by handling spaces better.
113 MA = (last_MA * 3 + rate) / 4
114 rate = (bytes - last_bytes) / (runtime - last_runtime)
115 - Add a recursive mark command (rmark) to restore.
116 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
117 of the same level and does not permit multiple simultaneous
118 running of that Job (i.e. lets any previous invocation finish
119 before doing Interval testing).
120 - Look at simplifying File exclusions.
122 - Auto update of slot:
123 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
124 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

128 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
129 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
130 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.

132 - Eliminate: /var is a different filesystem. Will not descend from / into /var
133 - Separate Files and Directories in catalog
134 - Create FileVersions table
135 - Look at rsysnc for incremental updates and dedupping
136 - Add MD5 or SHA1 check in SD for data validation
137 - finish implementation of fdcalled -- see ua_run.c:105
138 - Fix problem in postgresql.c in my_postgresql_query, where the
139 generation of the error message doesn't differentiate result==NULL
140 and a bad status from that result. Not only that, the result is
141 cleared on a bail_out without having generated the error message.
143 - Implement SDErrors (must return from SD)
144 - Implement USB keyboard support in rescue CD.
145 - Implement continue spooling while despooling.
146 - Remove all install temp files in Win32 PLUGINSDIR.
147 - Audit retention periods to make sure everything is 64 bit.
148 - No where in restore causes kaboom.
149 - Performance: multiple spool files for a single job.
150 - Performance: despool attributes when despooling data (problem
151 multiplexing Dir connection).
152 - Make restore use the in-use volume reservation algorithm.
153 - When Pool specifies Storage command override does not work.
154 - Implement wait_for_sysop() message display in wait_for_device(), which
155 now prints warnings too often.
156 - Ensure that each device in an Autochanger has a different
158 - Look at sg_logs -a /dev/sg0 for getting soft errors.
159 - btape "test" command with Offline on Unmount = yes
161 This test is essential to Bacula.
163 I'm going to write one record in file 0,
164 two records in file 1,
165 and three records in file 2
167 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715
168 dev.c:714 Bad call to rewind. Device "LTO" (/dev/nst0) not open
169 02-Feb 11:00 btape: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation
170 Kaboom! btape, btape got signal 11. Attempting traceback.
172 - Encryption -- email from Landon
173 > The backup encryption algorithm is currently not configurable, and is
174 > set to AES_128_CBC in src/filed/backup.c. The encryption code
175 > supports a number of different ciphers (as well as adding arbitrary

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

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

304 - Possibly allow SD to spool even if a tape is not mounted.
305 - Fix re-read of last block to check if job has actually written
306 a block, and check if block was written by a different job
307 (i.e. multiple simultaneous jobs writing).
308 - Figure out how to configure query.sql. Suggestion to use m4:
309 == changequote.m4 ===
310 changequote(`[',`]')dnl
311 ==== query.sql.in ===
312 :List next 20 volumes to expire
314 Pool.Name AS PoolName,
319 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
321 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
325 ON Media.PoolId=Pool.PoolId
326 WHERE Media.LastWritten>0
330 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
332 The problem is that it requires m4, which is not present on all machines
334 - Given all the problems with FIFOs, I think the solution is to do something a
335 little different, though I will look at the code and see if there is not some
336 simple solution (i.e. some bug that was introduced). What might be a better
337 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
338 write data to a program rather than the FIFO. For example, suppose you
343 Then, I could imagine if you backup and restore this file with a direct
344 reference as is currently done for fifos, instead, during backup Bacula will
347 /home/kern/my-fifo.backup
349 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
352 /home/kern/my-fifo.restore
354 and send the data backed up to stdout. These programs can either be an
355 executable or a shell script and they need only read/write to stdin/stdout.
357 I think this would give a lot of flexibility to the user without making any
358 significant changes to Bacula.

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

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

630 Do not forget to mount the drive!!!
631 - Bug: if a job is manually scheduled to run later, it does not appear
632 in any status report and cannot be cancelled.
634 ==== Keeping track of deleted/new files ====
635 - To mark files as deleted, run essentially a Verify to disk, and
636 when a file is found missing (MarkId != JobId), then create
637 a new File record with FileIndex == -1. This could be done
638 by the FD at the same time as the backup.
640 My "trick" for keeping track of deletions is the following.
641 Assuming the user turns on this option, after all the files
642 have been backed up, but before the job has terminated, the
643 FD will make a pass through all the files and send their
644 names to the DIR (*exactly* the same as what a Verify job
645 currently does). This will probably be done at the same
646 time the files are being sent to the SD avoiding a second
647 pass. The DIR will then compare that to what is stored in
648 the catalog. Any files in the catalog but not in what the
649 FD sent will receive a catalog File entry that indicates
650 that at that point in time the file was deleted. This
651 either transmitted to the FD or simultaneously computed in
652 the FD, so that the FD can put a record on the tape that
653 indicates that the file has been deleted at this point.
654 A delete file entry could potentially be one with a FileIndex
655 of 0 or perhaps -1 (need to check if FileIndex is used for
656 some other thing as many of the Bacula fields are "overloaded"
659 During a restore, any file initially picked up by some
660 backup (Full, ...) then subsequently having a File entry
661 marked "delete" will be removed from the tree, so will not
662 be restored. If a file with the same name is later OK it
663 will be inserted in the tree -- this already happens. All
664 will be consistent except for possible changes during the
667 Since I'm on the subject, some of you may be wondering what
668 the utility of the in memory tree is if you are going to
669 restore everything (at least it comes up from time to time
670 on the list). Well, it is still *very* useful because it
671 allows only the last item found for a particular filename
672 (full path) to be entered into the tree, and thus if a file
673 is backed up 10 times, only the last copy will be restored.
674 I recently (last Friday) restored a complete directory, and
675 the Full and all the Differential and Incremental backups
676 spanned 3 Volumes. The first Volume was not even mounted
677 because all the files had been updated and hence backed up
678 since the Full backup was made. In this case, the tree
679 saved me a *lot* of time.
681 Make sure this information is stored on the tape too so
682 that it can be restored directly from the tape.
684 All the code (with the exception of formally generating and
685 saving the delete file entries) already exists in the Verify
686 Catalog command. It explicitly recognizes added/deleted files since
687 the last InitCatalog. It is more or less a "simple" matter of
688 taking that code and adapting it slightly to work for backups.
690 Comments from Martin Simmons (I think they are all covered):
691 Ok, that should cover the basics. There are few issues though:
693 - Restore will depend on the catalog. I think it is better to include the
694 extra data in the backup as well, so it can be seen by bscan and bextract.
696 - I'm not sure if it will preserve multiple hard links to the same inode. Or
697 maybe adding or removing links will cause the data to be dumped again?
699 - I'm not sure if it will handle renamed directories. Possibly it will work
700 by dumping the whole tree under a renamed directory?
702 - It remains to be seen how the backup performance of the DIR's will be
703 affected when comparing the catalog for a large filesystem.
705 1. Use the current Director in-memory tree code (very fast), but currently in
706 memory. It probably could be paged.
708 2. Use some DB such as Berkeley DB or SQLite. SQLite is already compiled and
709 built for Win32, and it is something we could compile into the program.
711 3. Implement our own custom DB code.
713 Note, by appropriate use of Directives in the Director, we can dynamically
714 decide if the work is done in the Director or in the FD, and we can even
715 allow the user to choose.
717 === most recent accurate file backup/restore ===
718 Here is a sketch (i.e. more details must be filled in later) that I recently
719 made of an algorithm for doing Accurate Backup.
721 1. Dir informs FD that it is doing an Accurate backup and lookup done by
724 2. FD passes through the file system doing a normal backup based on normal
725 conditions, recording the names of all files and their attributes, and
726 indicating which files were backed up. This is very similar to what Verify
729 3. The Director receives the two lists of files at the end of the FD backup.
730 One, files backed up, and one files not backed up. It then looks up all the
731 files not backed up (using Verify style code).
733 4. The Dir sends the FD a list of:
734 a. Additional files to backup (based on user specified criteria, name, size
735 inode date, hash, ...).
738 5. Dir deletes list of file not backed up.
740 6. FD backs up additional files generates a list of those backed up and sends
741 it to the Director, which adds it to the list of files backed up. The list
742 is now complete and current.
744 7. The FD generates delete records for all the files that were deleted and
747 8. The Dir deletes the previous CurrentBackup list, and then does a
748 transaction insert of the new list that it has.
750 9. The rest works as before ...
754 Two new tables needed.
755 1. CurrentBackupId table that contains Client, JobName, FileSet, and a unique
756 BackupId. This is created during a Full save, and the BackupId can be set to
757 the JobId of the Full save. It will remain the same until another Full
758 backup is done. That is when new records are added during a Differential or
759 Incremental, they must use the same BackupId.
761 2. CurrentBackup table that contains essentially a File record (less a number
762 of fields, but with a few extra fields) -- e.g. a flag that the File was
763 backed up by a Full save (this permits doing a Differential). The unique
764 BackupId allows us to look up the CurrentBackup for a particular Client,
765 Jobname, FileSet using that unique BackupId as the key, so this table must be
766 indexed by the BackupId.
768 Note any time a file is saved by the FD other than during a Full save, the
769 Full save flag is cleared. When doing a Differential backup, if a file has
770 the Full save flag set, it is skipped, otherwise it is backed up. For an
771 Incremental backup, we check to see if the file has changed since the last
772 time we backed it up.
774 Deleted files should have FileIndex == 0
778 How about introducing a Type = MgmtPolicy job type? That job type would
779 be responsible for scanning the Bacula environment looking for specific
780 conditions, and submitting the appropriate jobs for implementing said
784 Name = "Migration-Policy"
786 Policy Selection Job Type = Migrate
787 Scope = "<keyword> <operator> <regexp>"
788 Threshold = "<keyword> <operator> <regexp>"
789 Job Template = <template-name>
792 Where <keyword> is any legal job keyword, <operator> is a comparison
793 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
794 appropriate regexp. I could see an argument for Scope and Threshold
795 being SQL queries if we want to support full flexibility. The
796 Migration-Policy job would then get scheduled as frequently as a site
797 felt necessary (suggested default: every 15 minutes).
802 Name = "Migration-Policy"
804 Policy Selection Job Type = Migration
806 Threshold = "Migration Selection Type = LowestUtil"
807 Job Template = "MigrationTemplate"
810 would select all pools for examination and generate a job based on
811 MigrationTemplate to automatically select the volume with the lowest
812 usage and migrate it's contents to the nextpool defined for that pool.
814 This policy abstraction would be really handy for adjusting the behavior
815 of Bacula according to site-selectable criteria (one thing that pops
816 into mind is Amanda's ability to automatically adjust backup levels
817 depending on various criteria).
823 - Add Pool/Storage override regression test.
824 - Add delete JobId to regression.
825 - Add a regression test for dbcheck.
826 - New test to add bscan to four-concurrent-jobs regression,
827 i.e. after the four-concurrent jobs zap the
828 database as is done in the bscan-test, then use bscan to
829 restore the database, do a restore and compare with the
831 - Add restore of specific JobId to regression (item 3
832 on the restore prompt)
833 - Add IPv6 to regression
834 - Add database test to regression. Test each function like delete,
837 - AntiVir can slow down backups on Win32 systems.
838 - Win32 systems with FAT32 can be much slower than NTFS for
839 more than 1000 files per directory.
843 - A HOLD command to stop all jobs from starting.
844 - A PAUSE command to pause all running jobs ==> release the
846 - Media Type = LTO,LTO-2,LTO-3
847 Media Type Read = LTO,LTO2,LTO3
848 Media Type Write = LTO2, LTO3
850 === From Carsten Menke <bootsy52@gmx.net>
852 Following is a list of what I think in the situations where I'm faced with,
853 could be a usefull enhancement to bacula, which I'm certain other users will
854 benefit from as well.
856 1. NextJob/NextJobs Directive within a Job Resource in the form of
857 NextJobs = job1,job2.
860 I currently solved the problem with running multiple jobs each after each
861 by setting the Max Wait Time for a job to 8 hours, and give
862 the jobs different Priorities. However, there scenarios where
863 1 Job is directly depending on another job, so if the former job fails,
864 the job after it needn't to be run
865 while maybe other jobs should run despite of that
868 A Backup Job and a Verify job, if the backup job fails there is no need to run
869 the verify job, as the backup job already failed. However, one may like
870 to backup the Catalog to disk despite of that the main backup job failed.
873 I see that this is related to the Event Handlers which are on the ToDo
874 list, also it is maybe a good idea to check for the return value and
875 execute different actions based on the return value
878 3. offline capability to bconsole
881 Currently I use a script which I execute within the last Job via the
882 RunAfterJob Directive, to release and eject the tape.
883 So I have to call bconsole "release=Storage-Name" and afterwards
884 mt -f /dev/nst0 eject to get the tape out.
886 If I have multiple Storage Devices, than these may not be /dev/nst0 and
887 I have to modify the script or call it with parameters etc.
888 This would actually not be needed, as everything is already defined
889 in bacula-sd.conf and if I can invoke bconsole with the
890 storage name via $1 in the script than I'm done and information is
893 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
897 For the reason mentioned in 3. to have the ability to call a
898 script with /scripts/foobar %s and in the script use $1
899 to pass the Storage Name to bconsole
901 5. Setting Volume State within a Job Resource
904 Instead of using "Maximum Volume Jobs" in the Pool Resource,
905 I would have the possibilty to define
906 in a Job Resource that after this certain job is run, the Volume State
907 should be set to "Volume State = Used", this give more flexibility (IMHO).
909 6. Localization of Bacula Messages
912 Unfortunatley many,many people I work with don't speak english very well.
913 So if at least the Reporting messages would be localized then they
914 would understand that they have to change the tape,etc. etc.
916 I volunteer to do the german translations, and if I can convince my wife also
917 french and Morre (western african language).
919 7. OK, this is evil, probably bound to security risks and maybe not possible
920 due to the design of bacula.
922 Implementation of Backtics ( `command` ) for shell comand execution to
923 the "Label Format" Directive.
927 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
928 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
929 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
930 the localized name for the day of the week appended to the
931 format string. Then I have the tape labeled automatically with weekday
932 name in the correct language.
934 - Make output from status use html table tags for nicely
935 presenting in a browser.
936 - Can one write tapes faster with 8192 byte block sizes?
937 - Document security problems with the same password for everyone in
938 rpm and Win32 releases.
939 - Browse generations of files.
940 - I've seen an error when my catalog's File table fills up. I
941 then have to recreate the File table with a larger maximum row
942 size. Relevant information is at
943 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
944 "Installing and Configuring MySQL" chapter should talk a bit
945 about this potential problem, and recommend a solution.
946 - For Solaris must use POSIX awk.
947 - Want speed of writing to tape while despooling.
948 - Supported autochanger:
956 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
957 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
958 - Add regex from http://www.pcre.org to Bacula for Win32.
959 - Use only shell tools no make in CDROM package.
960 - Include within include does it work?
961 - Implement a Pool of type Cleaning?
962 - Implement VolReadTime and VolWriteTime in SD
963 - Modify Backing up Your Database to include a bootstrap file.
964 - Think about making certain database errors fatal.
965 - Look at correcting the time jump in the scheduler for daylight
966 savings time changes.
967 - Add a "real" timer to network connections.
968 - Promote to Full = Time period
969 - Check dates entered by user for correctness (month/day/... ranges)
970 - Compress restore Volume listing by date and first file.
971 - Look at patches/bacula_db.b2z postgresql that loops during restore.
973 - Perhaps add read/write programs and/or plugins to FileSets.
974 - How to handle backing up portables ...
975 - Add some sort of guaranteed Interval for upgrading jobs.
976 - Can we write the state file after every job terminates? On Win32
977 the system crashes and the state file is not updated.
980 Documentation to do: (any release a little bit at a time)
981 - Doc to do unmount before removing magazine.
982 - Alternative to static linking "ldd prog" save all binaries listed,
983 restore them and point LD_LIBRARY_PATH to them.
984 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
985 - Document query file format.
986 - Add more documentation for bsr files.
987 - Document problems with Verify and pruning.
988 - Document how to use multiple databases.
989 - VXA drives have a "cleaning required"
990 indicator, but Exabyte recommends preventive cleaning after every 75
993 In this context, it should be noted that Exabyte has a command-line
994 vxatool utility available for free download. (The current version is
995 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
996 test the drive, unload tapes, change drive settings, flash new firmware,
998 Of particular interest in this context is that vxatool <device> -i will
999 report, among other details, the time since last cleaning in tape motion
1000 minutes. This information can be retrieved (and settings changed, for
1001 that matter) through the generic-SCSI device even when Bacula has the
1002 regular tape device locked. (Needless to say, I don't recommend
1003 changing tape settings while a job is running.)
1004 - Lookup HP cleaning recommendations.
1005 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
1006 - Document doing table repair
1009 ===================================
1010 - Add macro expansions in JobDefs.
1011 Run Before Job = "SomeFile %{Level} %{Client}"
1012 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
1013 - Use non-blocking network I/O but if no data is available, use
1015 - Use gather write() for network I/O.
1016 - Autorestart on crash.
1017 - Add bandwidth limiting.
1018 - Add acks every once and a while from the SD to keep
1019 the line from timing out.
1020 - When an error in input occurs and conio beeps, you can back
1021 up through the prompt.
1022 - Detect fixed tape block mode during positioning by looking at
1023 block numbers in btape "test". Possibly adjust in Bacula.
1024 - Fix list volumes to output volume retention in some other
1025 units, perhaps via a directive.
1026 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
1027 with multiple priorities.
1028 - If you use restore replace=never, the directory attributes for
1029 non-existent directories will not be restored properly.
1031 - see lzma401.zip in others directory for new compression
1033 - Allow the user to select JobType for manual pruning/purging.
1034 - bscan does not put first of two volumes back with all info in
1036 - Implement the FreeBSD nodump flag in chflags.
1037 - Figure out how to make named console messages go only to that
1038 console and to the non-restricted console (new console class?).
1039 - Make restricted console prompt for password if *ask* is set or
1040 perhaps if password is undefined.
1041 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1044 ==== from Marc Schoechlin
1045 - the help-command should be more verbose
1046 (it should explain the paramters of the different
1048 -> its time-comsuming to consult the manual anytime
1049 you need a special parameter
1050 -> maybe its more easy to maintain this, if the
1051 descriptions of that commands are outsourced to
1053 - if the password is not configured in bconsole.conf
1054 you should be asked for it.
1055 -> sometimes you like to do restore on a customer-machine
1056 which shouldnt know the password for bacula.
1057 -> adding the password to the file favours admins
1058 to forget to remove the password after usage
1060 the protection of that file is less important
1061 - long-listed-output of commands should be scrollable
1062 like the unix more/less-command does
1063 -> if someone runs 200 and more machines, the lists could
1064 be a little long and complex
1065 - command-output should be shown column by column
1066 to reduce scrolling and to increase clarity
1068 - lsmark should list the selected files with full
1070 - wildcards for selecting and file and directories would be nice
1071 - any actions should be interuptable with STRG+C
1072 - command-expansion would be pretty cool
1074 - When the replace Never option is set, new directory permissions
1075 are not restored. See bug 213. To fix this requires creating a
1076 list of newly restored directories so that those directory
1077 permissions *can* be restored.
1078 - Add prune all command
1079 - Document fact that purge can destroy a part of a restore by purging
1080 one volume while others remain valid -- perhaps mark Jobs.
1081 - Add multiple-media-types.txt
1082 - look at mxt-changer.html
1083 - Make ? do a help command (no return needed).
1084 - Implement restore directory.
1085 - Document streams and how to implement them.
1086 - Try not to re-backup a file if a new hard link is added.
1087 - Add feature to backup hard links only, but not the data.
1088 - Fix stream handling to be simpler.
1089 - Add Priority and Bootstrap to Run a Job.
1090 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1092 - Remove View FileSet button from Run a Job dialog.
1093 - Handle prompt for restore job at end of Restore command.
1094 - Add display of total selected files to Restore window.
1095 - Add tree pane to left of window.
1096 - Add progress meter.
1097 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1098 - Add message to user to check for fixed block size when the forward
1099 space test fails in btape.
1100 - When unmarking a directory check if all files below are unmarked and
1101 then remove the + flag -- in the restore tree.
1102 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1103 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1104 - Revisit the question of multiple Volumes (disk) on a single device.
1105 - Add a block copy option to bcopy.
1106 - Finish work on Gnome restore GUI.
1107 - Fix "llist jobid=xx" where no fileset or client exists.
1108 - For each job type (Admin, Restore, ...) require only the really necessary
1109 fields.- Pass Director resource name as an option to the Console.
1110 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1111 - Add a .list all files in the restore tree (probably also a list all files)
1112 Do both a long and short form.
1113 - Allow browsing the catalog to see all versions of a file (with
1114 stat data on each file).
1115 - Restore attributes of directory if replace=never set but directory
1117 - Use SHA1 on authentication if possible.
1118 - See comtest-xxx.zip for Windows code to talk to USB.
1119 - Add John's appended files:
1120 Appended = { /files/server/logs/http/*log }
1121 and such files would be treated as follows.On a FULL backup, they would
1122 be backed up like any other file.On an INCREMENTAL backup, where a
1123 previous INCREMENTAL or FULL was already in thecatalogue and the length
1124 of the file wasgreater than the length of the last backup, only thedata
1125 added since the last backup will be dumped.On an INCREMENTAL backup, if
1126 the length of the file is less than thelength of the file with the same
1127 name last backed up, the completefile is dumped.On Windows systems, with
1128 creation date of files, we can be evensmarter about this and not count
1129 entirely upon the length.On a restore, the full and all incrementals
1130 since it will beapplied in sequence to restore the file.
1131 - Check new HAVE_WIN32 open bits.
1132 - Check if the tape has moved before writing.
1133 - Handling removable disks -- see below:
1134 - Keep track of tape use time, and report when cleaning is necessary.
1135 - Add FromClient and ToClient keywords on restore command (or
1136 BackupClient RestoreClient).
1137 - Implement a JobSet, which groups any number of jobs. If the
1138 JobSet is started, all the jobs are started together.
1139 Allow Pool, Level, and Schedule overrides.
1140 - Enhance cancel to timeout BSOCK packets after a specific delay.
1141 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1142 ua_status.!!! Thanks to Alan Brown for this tip.
1143 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1144 correctly for multiple simultaneous jobs.
1145 - Correct code so that FileSet MD5 is calculated for < and | filename
1147 - Implement the Media record flag that indicates that the Volume does disk
1149 - Implement VolAddr, which is used when Volume is addressed like a disk,
1150 and form it from VolFile and VolBlock.
1151 - Make multiple restore jobs for multiple media types specifying
1152 the proper storage type.
1153 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1154 pointer (rec) to try_repositioning().
1155 - Look at extracting Win data from BackupRead.
1156 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1157 which would take precidence over the Catalog "JobRetention".
1158 - Implement Label Format in Add and Label console commands.
1159 - Possibly up network buffers to 65K. Put on variable.
1160 - Put email tape request delays on one or more variables. User wants
1161 to cancel the job after a certain time interval. Maximum Mount Wait?
1162 - Job, Client, Device, Pool, or Volume?
1163 Is it possible to make this a directive which is *optional* in multiple
1164 resources, like Level? If so, I think I'd make it an optional directive
1165 in Job, Client, and Pool, with precedence such that Job overrides Client
1166 which in turn overrides Pool.
1168 - New Storage specifications:
1169 - Want to write to multiple storage devices simultaneously
1170 - Want to write to multiple storage devices sequentially (in one job)
1171 - Want to read/write simultaneously
1172 - Key is MediaType -- it must match
1174 Passed to SD as a sort of BSR record called Storage Specification
1178 MediaType -> Next MediaType
1180 Device -> Next Device
1182 Allow multiple Storage specifications
1190 Allow Multiple Pool specifications (note, Pool currently
1192 Allow Multiple MediaType specifications in Dir conf
1193 Allow Multiple Device specifications in Dir conf
1194 Perhaps keep this in a single SSR
1195 Tie a Volume to a specific device by using a MediaType that
1196 is contained in only one device.
1197 In SD allow Device to have Multiple MediaTypes
1199 - Ideas from Jerry Scharf:
1200 First let's point out some big pluses that bacula has for this
1202 more importantly it's active. Thank you so much for that
1203 even more important, it's not flaky
1204 it has an open access catalog, opening many possibilities
1205 it's pushing toward heterogeneous systems capability
1207 Macintosh file client
1208 macs are an interesting niche, but I fear a server is a rathole
1209 working bare iron recovery for windows
1210 the option for inc/diff backups not reset on fileset revision
1211 a) use both change and inode update time against base time
1212 b) do the full catalog check (expensive but accurate)
1213 sizing guide (how much system is needed to back up N systems/files)
1214 consultants on using bacula in building a disaster recovery system
1215 an integration guide
1216 or how to get at fancy things that one could do with bacula
1217 logwatch code for bacula logs (or similar)
1218 linux distro inclusion of bacula (brings good and bad, but necessary)
1219 win2k/XP server capability (icky but you asked)
1220 support for Oracle database ??
1222 - Look at adding SQL server and Exchange support for Windows.
1223 - Make dev->file and dev->block_num signed integers so that -1 can
1224 be an invalid value which happens with BSR.
1225 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1226 is needed to properly specify ranges.
1227 - Add progress of files/bytes to SD and FD.
1228 - Print warning message if FileId > 4 billion
1229 - do a "messages" before the first prompt in Console
1230 - Client does not show busy during Estimate command.
1231 - Implement Console mtx commands.
1232 - Implement a Mount Command and an Unmount Command where
1233 the users could specify a system command to be performed
1234 to do the mount, after which Bacula could attempt to
1235 read the device. This is for Removeable media such as a CDROM.
1236 - Most likely, this mount command would be invoked explicitly
1237 by the user using the current Console "mount" and "unmount"
1238 commands -- the Storage Daemon would do the right thing
1239 depending on the exact nature of the device.
1240 - As with tape drives, when Bacula wanted a new removable
1241 disk mounted, it would unmount the old one, and send a message
1242 to the user, who would then use "mount" as described above
1243 once he had actually inserted the disk.
1244 - Implement dump/print label to UA
1245 - Spool to disk only when the tape is full, then when a tape is hung move
1247 - bextract is sending everything to the log file ****FIXME****
1248 - Allow multiple Storage specifications (or multiple names on
1249 a single Storage specification) in the Job record. Thus a job
1250 can be backed up to a number of storage devices.
1251 - Implement some way for the File daemon to contact the Director
1252 to start a job or pass its DHCP obtained IP number.
1253 - Implement a query tape prompt/replace feature for a console
1254 - Copy console @ code to gnome2-console
1255 - Make sure that Bacula rechecks the tape after the 20 min wait.
1256 - Set IO_NOWAIT on Bacula TCP/IP packets.
1257 - Try doing a raw partition backup and restore by mounting a
1259 - From Lars Kellers:
1260 Yes, it would allow to highly automatic the request for new tapes. If a
1261 tape is empty, bacula reads the barcodes (native or simulated), and if
1262 an unused tape is found, it runs the label command with all the
1263 necessary parameters.
1265 By the way can bacula automatically "move" an empty/purged volume say
1266 in the "short" pool to the "long" pool if this pool runs out of volume
1268 - What to do about "list files job=xxx".
1269 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1270 file descriptor leak in Bacula.
1271 - Implement WrapCounters in Counters.
1272 - Add heartbeat from FD to SD if hb interval expires.
1273 - Can we dynamically change FileSets?
1274 - If pool specified to label command and Label Format is specified,
1275 automatically generate the Volume name.
1276 - Why can't SQL do the filename sort for restore?
1277 - Add ExhautiveRestoreSearch
1278 - Look at the possibility of loading only the necessary
1279 data into the restore tree (i.e. do it one directory at a
1280 time as the user walks through the tree).
1281 - Possibly use the hash code if the user selects all for a restore command.
1282 - Fix "restore all" to bypass building the tree.
1283 - Prohibit backing up archive device (findlib/find_one.c:128)
1284 - Implement Release Device in the Job resource to unmount a drive.
1285 - Implement Acquire Device in the Job resource to mount a drive,
1286 be sure this works with admin jobs so that the user can get
1287 prompted to insert the correct tape. Possibly some way to say to
1288 run the job but don't save the files.
1289 - Make things like list where a file is saved case independent for
1291 - Use autochanger to handle multiple devices.
1292 - Implement a Recycle command
1293 - Start working on Base jobs.
1294 - Implement UnsavedFiles DB record.
1295 - From Phil Stracchino:
1296 It would probably be a per-client option, and would be called
1297 something like, say, "Automatically purge obsoleted jobs". What it
1298 would do is, when you successfully complete a Differential backup of a
1299 client, it would automatically purge all Incremental backups for that
1300 client that are rendered redundant by that Differential. Likewise,
1301 when a Full backup on a client completed, it would automatically purge
1302 all Differential and Incremental jobs obsoleted by that Full backup.
1303 This would let people minimize the number of tapes they're keeping on
1304 hand without having to master the art of retention times.
1305 - When doing a Backup send all attributes back to the Director, who
1306 would then figure out what files have been deleted.
1307 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1308 explicit permission to do so. It should also mark the tape in error
1309 if there is an error.
1310 - Cancel waiting for Client connect in SD if FD goes away.
1312 - Implement timeout in response() when it should come quickly.
1313 - Implement a Slot priority (loaded/not loaded).
1314 - Implement "vacation" Incremental only saves.
1315 - Implement create "FileSet"?
1316 - Add prefixlinks to where or not where absolute links to FD.
1317 - Issue message to mount a new tape before the rewind.
1318 - Simplified client job initiation for portables.
1319 - If SD cannot open a drive, make it periodically retry.
1320 - Add more of the config info to the tape label.
1322 - Refine SD waiting output:
1323 Device is being positioned
1324 > Device is being positioned for append
1325 > Device is being positioned to file x
1327 - Figure out some way to estimate output size and to avoid splitting
1328 a backup across two Volumes -- this could be useful for writing CDROMs
1329 where you really prefer not to have it split -- not serious.
1330 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1331 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1332 actual data on the Volume and compare it.
1333 - Make bcopy read through bad tape records.
1334 - Program files (i.e. execute a program to read/write files).
1335 Pass read date of last backup, size of file last time.
1336 - Add Signature type to File DB record.
1337 - CD into subdirectory when open()ing files for backup to
1338 speed up things. Test with testfind().
1339 - Priority job to go to top of list.
1340 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1341 - Implement some way for the Console to dynamically create a job.
1342 - Solaris -I on tar for include list
1343 - Need a verbose mode in restore, perhaps to bsr.
1344 - bscan without -v is too quiet -- perhaps show jobs.
1345 - Add code to reject whole blocks if not wanted on restore.
1346 - Check if we can increase Bacula FD priorty in Win2000
1347 - Make sure the MaxVolFiles is fully implemented in SD
1348 - Check if both CatalogFiles and UseCatalog are set to SD.
1349 - Possibly add email to Watchdog if drive is unmounted too
1350 long and a job is waiting on the drive.
1351 - After unmount, if restore job started, ask to mount.
1352 - Add UA rc and history files.
1353 - put termcap (used by console) in ./configure and
1354 allow -with-termcap-dir.
1355 - Fix Autoprune for Volumes to respect need for full save.
1356 - Compare tape to Client files (attributes, or attributes and data)
1357 - Make all database Ids 64 bit.
1358 - Allow console commands to detach or run in background.
1359 - Add SD message variables to control operator wait time
1360 - Maximum Operator Wait
1361 - Minimum Message Interval
1362 - Maximum Message Interval
1363 - Send Operator message when cannot read tape label.
1364 - Verify level=Volume (scan only), level=Data (compare of data to file).
1365 Verify level=Catalog, level=InitCatalog
1367 - Add keyword search to show command in Console.
1368 - Events : tape has more than xxx bytes.
1369 - Complete code in Bacula Resources -- this will permit
1370 reading a new config file at any time.
1371 - Handle ctl-c in Console
1372 - Implement script driven addition of File daemon to config files.
1373 - Think about how to make Bacula work better with File (non-tape) archives.
1374 - Write Unix emulator for Windows.
1375 - Put memory utilization in Status output of each daemon
1376 if full status requested or if some level of debug on.
1377 - Make database type selectable by .conf files i.e. at runtime
1378 - Set flag for uname -a. Add to Volume label.
1379 - Restore files modified after date
1380 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1381 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1382 - Timout a job or terminate if link goes down, or reopen link and query.
1383 - Concept of precious tapes (cannot be reused).
1384 - Make bcopy copy with a single tape drive.
1385 - Permit changing ownership during restore.

1399 - Autolabel should be specified by DIR instead of SD.
1401 - Add media capacity
1402 - AutoScan (check checksum of tape)
1403 - Format command = "format /dev/nst0"
1407 - Seek resolution (usually corresponds to buffer size)
1408 - EODErrorCode=ENOSPC or code
1409 - Partial Read error code
1410 - Partial write error code
1411 - Nonformatted read error
1412 - Nonformatted write error
1413 - WriteProtected error
1417 - IgnoreCloseErrors=yes
1427 - FD sends unsaved file list to Director at end of job (see
1429 - File daemon should build list of files skipped, and then
1430 at end of save retry and report any errors.
1431 - Write a Storage daemon that uses pipes and
1432 standard Unix programs to write to the tape.
1434 - Need something that monitors the JCR queue and
1435 times out jobs by asking the deamons where they are.
1436 - Enhance Jmsg code to permit buffering and saving to disk.
1437 - device driver = "xxxx" for drives.
1438 - Verify from Volume
1439 - Ensure that /dev/null works
1440 - Need report class for messages. Perhaps
1441 report resource where report=group of messages
1442 - enhance scan_attrib and rename scan_jobtype, and
1443 fill in code for "since" option
1444 - Director needs a time after which the report status is sent
1445 anyway -- or better yet, a retry time for the job.
1446 - Don't reschedule a job if previous incarnation is still running.
1447 - Some way to automatically backup everything is needed????
1448 - Need a structure for pending actions:
1450 - termination status (part of buffered msgs?)
1452 Read, Write, Clean, Delete
1453 - Login to Bacula; Bacula users with different permissions:
1454 owner, group, user, quotas
1455 - Store info on each file system type (probably in the job header on tape.
1456 This could be the output of df; or perhaps some sort of /etc/mtab record.
1458 ========= ideas ===============
1459 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1460 To: <kern@sibbald.com>
1461 Subject: RE: [Bacula-users] future large programming jobs
1462 Date: Thu, 26 Feb 2004 11:34:54 -0600
1464 I noticed the subject thread and thought I would offer the following
1465 merely as sources of ideas, i.e. something to think about, not even as
1466 strong as a request. In my former life (before retiring) I often
1467 dealt with backups and storage management issues/products as a
1468 developer and as a consultant. I am currently migrating my personal
1469 network from amanda to bacula specifically because of the ability to
1470 cross media boundaries during storing backups.
1471 Are you familiar with the commercial product called ADSM (I think IBM
1472 now sells it under the Tivoli label)? It has a couple of interesting
1473 ideas that may apply to the following topics.
1475 1. Migration: Consider that when you need to restore a system, there
1476 may be pressure to hurry. If all the information for a single client
1477 can eventually end up on the same media (and in chronological order),
1478 the restore is facillitated by not having to search past information
1479 from other clients. ADSM has the concept of "client affinity" that
1480 may be associated with it's storage pools. It seems to me that this
1481 concept (as an optional feature) might fit in your architecture for
1484 ADSM also has the concept of defining one or more storage pools as
1485 "copy pools" (almost mirrors, but only in the sense of contents).
1486 These pools provide the ability to have duplicte data stored both
1487 onsite and offsite. The copy process can be scheduled to be handled
1488 by their storage manager during periods when there is no backup
1489 activity. Again, the migration process might be a place to consider
1490 implementing something like this.
1493 > It strikes me that it would be very nice to be able to do things
1495 > have the Job(s) backing up the machines run, and once they have all

1501 > mechanism described below would probably make it very easy.
1503 This is the goal. In the first step (before events), you simply
1505 the Migration to tape later.
1507 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1508 the database. Once a file (unique by path and metadata such as dates,
1509 size, ownership, etc.) is in a copy pool, no more copies are made. In
1510 other words, when you start ADSM, it begins like your concept of a
1511 base job. After that it is in the "incremental" mode. You can
1512 configure the number of "generations" of files to be retained, plus a
1513 retention date after which even old generations are purged. The
1514 database tracks the contents of media and projects the percentage of
1515 each volume that is valid. When the valid content of a volume drops
1516 below a configured percentage, the valid data are migrated to another
1517 volume and the old volume is marked as empty. Note, this requires
1518 ADSM to have an idea of the contents of a client, i.e. marking the
1519 database when an existing file was deleted, but this would solve your
1520 issue of restoring a client without restoring deleted files.
1522 This is pretty far from what bacula now does, but if you are going to
1523 rip things up for Base jobs,.....
1524 Also, the benefits of this are huge for very large shops, especially
1525 with media robots, but are a pain for shops with manual media
1529 > Base jobs sound pretty useful, but I'm not dying for them.
1531 Nobody is dying for them, but when you see what it does, you will die
1534 3. Restoring deleted files: Since I think my comments in (2) above
1535 have low probability of implementation, I'll also suggest that you
1536 could approach the issue of deleted files by a mechanism of having the
1537 fd report to the dir, a list of all files on the client for every
1538 backup job. The dir could note in the database entry for each file
1539 the date that the file was seen. Then if a restore as of date X takes
1540 place, only files that exist from before X until after X would be
1541 restored. Probably the major cost here is the extra date container in
1542 each row of the files table.
1544 Thanks for "listening". I hope some of this helps. If you want to
1545 contact me, please send me an email - I read some but not all of the
1546 mailing list traffic and might miss a reply there.
1548 Please accept my compliments for bacula. It is doing a great job for
1549 me!! I sympathize with you in the need to wrestle with excelence in
1550 execution vs. excelence in feature inclusion.
1555 ==============================
1558 - Design at hierarchial storage for Bacula. Migration and Clone.
1559 - Implement FSM (File System Modules).
1560 - Audit M_ error codes to ensure they are correct and consistent.
1561 - Add variable break characters to lex analyzer.
1562 Either a bit mask or a string of chars so that
1563 the caller can change the break characters.
1564 - Make a single T_BREAK to replace T_COMMA, etc.
1565 - Ensure that File daemon and Storage daemon can
1566 continue a save if the Director goes down (this
1567 is NOT currently the case). Must detect socket error,
1568 buffer messages for later.
1569 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1570 - Add ability to backup to two Storage devices (two SD sessions) at
1571 the same time -- e.g. onsite, offsite.
1572 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1573 someway to do so with every volume that has less than x% valid
1577 Migration: Move a backup from one Volume to another
1578 Clone: Copy a backup -- two Volumes
1581 ======================================================
1583 It is somewhat like a Full save becomes an incremental since
1584 the Base job (or jobs) plus other non-base files.
1586 - A Base backup is same as Full backup, just different type.
1587 - New BaseFiles table that contains:
1589 BaseJobId - Base JobId referenced for this FileId (needed ???)
1590 JobId - JobId currently running
1591 FileId - File not backed up, exists in Base Job
1592 FileIndex - FileIndex from Base Job.
1593 i.e. for each base file that exists but is not saved because
1594 it has not changed, the File daemon sends the JobId, BaseId,
1595 FileId, FileIndex back to the Director who creates the DB entry.
1596 - To initiate a Base save, the Director sends the FD
1597 the FileId, and full filename for each file in the Base.
1598 - When the FD finds a Base file, he requests the Director to
1599 send him the full File entry (stat packet plus MD5), or
1600 conversely, the FD sends it to the Director and the Director
1601 says yes or no. This can be quite rapid if the FileId is kept
1602 by the FD for each Base Filename.
1603 - It is probably better to have the comparison done by the FD
1604 despite the fact that the File entry must be sent across the
1606 - An alternative would be to send the FD the whole File entry
1607 from the start. The disadvantage is that it requires a lot of
1608 space. The advantage is that it requires less communications
1610 - The Job record must be updated to indicate that one or more
1612 - At end of Job, FD returns:
1613 1. Count of base files/bytes not written to tape (i.e. matches)
1614 2. Count of base file that were saved i.e. had changed.
1615 - No tape record would be written for a Base file that matches, in the
1616 same way that no tape record is written for Incremental jobs where
1617 the file is not saved because it is unchanged.
1618 - On a restore, all the Base file records must explicitly be
1619 found from the BaseFile tape. I.e. for each Full save that is marked
1620 to have one or more Base Jobs, search the BaseFile for all occurrences
1622 - An optimization might be to make the BaseFile have:
1628 This would avoid the need to explicitly fetch each File record for
1629 the Base job. The Base Job record will be fetched to get the
1630 VolSessionId and VolSessionTime.

1671 Unloading Data Transfer Element into Storage Element 15...done
1673 (just to verify it remembers where it came from, however it can be
1674 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1676 There needs to be a table of drive # to devices somewhere - If there are
1677 multiple changers or drives there may not be a 1:1 correspondance between
1678 changer drive number and system device name - and depending on the way the
1679 drives are hooked up to scsi busses, they may not be linearly numbered
1680 from an offset point either.something like
1682 Autochanger drives = 2
1683 Autochanger drive 0 = /dev/nst1
1684 Autochanger drive 1 = /dev/nst2
1685 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1686 times, not just for multidrive changers. For a 1 drive changer, that's
1692 MTX's manpage (1.2.15):
1693 unload [<slotnum>] [ <drivenum> ]
1694 Unloads media from drive <drivenum> into slot
1695 <slotnum>. If <drivenum> is omitted, defaults to
1696 drive 0 (as do all commands). If <slotnum> is
1697 omitted, defaults to the slot that the drive was
1698 loaded from. Note that there's currently no way
1699 to say 'unload drive 1's media to the slot it
1700 came from', other than to explicitly use that
1701 slot number as the destination.AB

1739 Handling removable disks
1741 From: Karl Cunningham <karlc@keckec.com>
1743 My backups are only to hard disk these days, in removable bays. This is my
1744 idea of how a backup to hard disk would work more smoothly. Some of these
1745 things Bacula does already, but I mention them for completeness. If others
1746 have better ways to do this, I'd like to hear about it.
1748 1. Accommodate several disks, rotated similar to how tapes are. Identified
1749 by partition volume ID or perhaps by the name of a subdirectory.
1750 2. Abort & notify the admin if the wrong disk is in the bay.
1751 3. Write backups to different subdirectories for each machine to be backed
1753 4. Volumes (files) get created as needed in the proper subdirectory, one
1755 5. When a disk is recycled, remove or zero all old backup files. This is
1756 important as the disk being recycled may be close to full. This may be
1757 better done manually since the backup files for many machines may be
1758 scattered in many subdirectories.
1763 - Why the heck doesn't bacula drop root priviledges before connecting to
1765 - Look at using posix_fadvise(2) for backups -- see bug #751.
1766 Possibly add the code at findlib/bfile.c:795
1767 /* TCP socket options */
1768 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1769 - Fix bnet_connect() code to set a timer and to use time to
1771 - Implement 4th argument to make_catalog_backup that passes hostname.
1772 - Test FIFO backup/restore -- make regression
1773 - Please mount volume "xxx" on Storage device ... should also list
1774 Pool and MediaType in case user needs to create a new volume.
1775 - On restore add Restore Client, Original Client.

1784 - Check if gnome-console works with TLS.
1785 - the director seg faulted when I omitted the pool directive from a
1786 job resource. I was experimenting and thought it redundant that I had
1787 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1788 apparently not. This happened when I removed the pool directive and
1789 started the director.
1790 - Add Where: client:/.... to restore job report.
1791 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1792 does the right thing.
1793 - FD-SD quick disconnect
1794 - Building the in memory restore tree is slow.
1795 - Erabt if min_block_size > max_block_size
1796 - Add the ability to consolidate old backup sets (basically do a restore
1797 to tape and appropriately update the catalog). Compress Volume sets.
1798 Might need to spool via file is only one drive is available.
1799 - Why doesn't @"xxx abc" work in a conf file?
1800 - Don't restore Solaris Door files:
1801 #define S_IFDOOR in st_mode.
1802 see: http://docs.sun.com/app/docs/doc/816-5173/6mbb8ae23?a=view#indexterm-360
1803 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
1804 - Implement Despooling data status.
1805 - Use E'xxx' to escape PostgreSQL strings.
1806 - Look at mincore: http://insights.oetiker.ch/linux/fadvise.html
1807 - Unicode input http://en.wikipedia.org/wiki/Byte_Order_Mark
1808 - Look at moving the Storage directive from the Job to the
1809 Pool in the default conf files.
1810 - Look at in src/filed/backup.c
1811 > pm_strcpy(ff_pkt->fname, ff_pkt->fname_save);
1812 > pm_strcpy(ff_pkt->link, ff_pkt->link_save);
1813 - Add Catalog = to Pool resource so that pools will exist
1814 in only one catalog -- currently Pools are "global".
1815 - Add TLS to bat (should be done).
1816 === Duplicate jobs ===
1817 hese apply only to backup jobs.
1819 1. Allow Duplicate Jobs = Yes | No | Higher (Yes)
1821 2. Duplicate Job Interval = <time-interval> (0)
1823 The defaults are in parenthesis and would produce the same behavior as today.
1825 If Allow Duplicate Jobs is set to No, then any job starting while a job of the
1826 same name is running will be canceled.
1828 If Allow Duplicate Jobs is set to Higher, then any job starting with the same
1829 or lower level will be canceled, but any job with a Higher level will start.
1830 The Levels are from High to Low: Full, Differential, Incremental
1832 Finally, if you have Duplicate Job Interval set to a non-zero value, any job
1833 of the same name which starts <time-interval> after a previous job of the
1834 same name would run, any one that starts within <time-interval> would be
1835 subject to the above rules. Another way of looking at it is that the Allow
1836 Duplicate Jobs directive will only apply after <time-interval> of when the
1837 previous job finished (i.e. it is the minimum interval between jobs).
1841 Allow Duplicate Jobs = Yes | No | HigherLevel | CancelLowerLevel (Yes)
1843 Where HigherLevel cancels any waiting job but not any running job.
1844 Where CancelLowerLevel is same as HigherLevel but cancels any running job or
1847 Duplicate Job Proximity = <time-interval> (0)
1849 My suggestion was to define it as the minimum guard time between
1850 executions of a specific job -- ie, if a job was scheduled within Job
1851 Proximity number of seconds, it would be considered a duplicate and
1854 Skip = Do not allow two or more jobs with the same name to run
1855 simultaneously within the proximity interval. The second and subsequent
1856 jobs are skipped without further processing (other than to note the job
1857 and exit immediately), and are not considered errors.
1859 Fail = The second and subsequent jobs that attempt to run during the
1860 proximity interval are cancelled and treated as error-terminated jobs.
1862 Promote = If a job is running, and a second/subsequent job of higher
1863 level attempts to start, the running job is promoted to the higher level
1864 of processing using the resources already allocated, and the subsequent
1865 job is treated as in Skip above.
1871 Allow = yes|no (no = default)
1873 AllowHigherLevel = yes|no (no)
1875 AllowLowerLevel = yes|no (no)
1877 AllowSameLevel = yes|no
1879 Cancel = Running | New (no)
1881 CancelledStatus = Fail | Skip (fail)
1883 Job Proximity = <time-interval> (0)
1884 My suggestion was to define it as the minimum guard time between
1885 executions of a specific job -- ie, if a job was scheduled within Job
1886 Proximity number of seconds, it would be considered a duplicate and
