27 === Migration from David ===
31 Name = "<poolname>-migrate"
35 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
36 Client | PoolResidence | Volume | JobName | SQLquery
37 Migration Selection Pattern = "regexp"
38 Next Pool = <override>
41 There should be no need for a Level (migration is always Full, since you
42 don't calculate differential/incremental differences for migration),
43 Storage should be determined by the volume types in the pool, and Client
44 is really a selection issue. Migration should always occur to the
45 NextPool defined in the pool definition. If no nextpool is defined, the
46 job should end with a reason of "no place to go". If Next Pool statement
47 is present, we override the check in the pool definition and use the
50 Here's how I'd define Migration Selection Types:
53 Client -- Migrate data from selected client only. Migration Selection
54 Pattern regexp provides pattern to select client names, eg ^FS00* makes
55 all client names starting with FS00 eligible for migration.
57 Jobname -- Migration all jobs matching name. Migration Selection Pattern
58 regexp provides pattern to select jobnames existing in pool.
60 Volume -- Migrate all data on specified volumes. Migration Selection
61 Pattern regexp provides selection criteria for volumes to be migrated.
62 Volumes must exist in pool to be eligible for migration.
66 LowestUtil -- Identify the volume in the pool with the least data on it
67 and empty it. No Migration Selection Pattern required.
69 OldestVol -- Identify the LRU volume with data written, and empty it. No
70 Migration Selection Pattern required.
72 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
73 (starting with most full volumes) until pool occupancy drops below
74 <lowmig>. Pool highmig and lowmig values are in pool definition, no
75 Migration Selection Pattern required.
79 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
80 Migration Selection Pattern contains SQL query to execute; should return
81 a list of 1 or more jobuids to migrate.
83 PoolResidence -- Migrate data sitting in pool for longer than
84 PoolResidence value in pool definition. Migration Selection Pattern
85 optional; if specified, override value in pool definition (value in

129 - Look at simplifying File exclusions.
130 - New directive "Delete purged Volumes"
131 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and

147 - From: Arunav Mandal <amandal@trolltech.com>
148 1. When jobs are running and bacula for some reason crashes or if I do a
149 restart it remembers and jobs it was running before it crashed or restarted
150 as of now I loose all jobs if I restart it.
152 2. When spooling and in the midway if client is disconnected for instance a
153 laptop bacula completely discard the spool. It will be nice if it can write
154 that spool to tape so there will be some backups for that client if not all.
156 3. We have around 150 clients machines it will be nice to have a option to
157 upgrade all the client machines bacula version automatically.
159 4. Atleast one connection should be reserved for the bconsole so at heavy load
160 I should connect to the director via bconsole which at sometimes I can't
162 5. Another most important feature that is missing, say at 10am I manually
163 started backup of client abc and it was a full backup since client abc has
164 no backup history and at 10.30am bacula again automatically started backup of
165 client abc as that was in the schedule. So now we have 2 multiple Full
166 backups of the same client and if we again try to start a full backup of
167 client backup abc bacula won't complain. That should be fixed.
169 - Fix bpipe.c so that it does not modify results pointer.
170 ***FIXME*** calling sequence should be changed.
171 - For Windows disaster recovery see http://unattended.sf.net/
172 - regardless of the retention period, Bacula will not prune the
173 last Full, Diff, or Inc File data until a month after the
174 retention period for the last Full backup that was done.
175 - update volume=xxx --- add status=Full
176 - Remove old spool files on startup.
177 - Exclude SD spool/working directory.
178 - Refuse to prune last valid Full backup. Same goes for Catalog.
180 - Make a callback when Rerun failed levels is called.
181 - Give Python program access to Scheduled jobs.
182 - Add setting Volume State via Python.
183 - Python script to save with Python, not save, save with Bacula.
184 - Python script to do backup.
186 - Change the Priority, Client, Storage, JobStatus (error)
187 at the start of a job.
188 - Why is SpoolDirectory = /home/bacula/spool; not reported
189 as an error when writing a DVD?
190 - Make bootstrap file handle multiple MediaTypes (SD)
191 - Remove all old Device resource code in Dir and code to pass it
192 back in SD -- better, rework it to pass back device statistics.
193 - Check locking of resources -- be sure to lock devices where previously
194 resources were locked.
195 - The last part is left in the spool dir.
198 - In restore don't compare byte count on a raw device -- directory
199 entry does not contain bytes.
200 - To mark files as deleted, run essentially a Verify to disk, and
201 when a file is found missing (MarkId != JobId), then create
202 a new File record with FileIndex == -1. This could be done
203 by the FD at the same time as the backup.
207 MA = (last_MA * 3 + rate) / 4
208 rate = (bytes - last_bytes) / (runtime - last_runtime)
209 - Max Vols limit in Pool off by one?
210 - Implement Files/Bytes,... stats for restore job.
211 - Implement Total Bytes Written, ... for restore job.
212 - Despool attributes simultaneously with data in a separate
213 thread, rejoined at end of data spooling.
214 - 7. Implement new Console commands to allow offlining/reserving drives,
215 and possibly manipulating the autochanger (much asked for).
216 - Add start/end date editing in messages (%t %T, %e?) ...
217 - Add ClientDefs similar to JobDefs.
218 - Print more info when bextract -p accepts a bad block.
219 - Fix FD JobType to be set before RunBeforeJob in FD.
220 - Look at adding full Volume and Pool information to a Volume
221 label so that bscan can get *all* the info.
222 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
223 and there is only one volume in the pool, refuse to do it -- otherwise
224 he fills the Volume, then immediately starts reusing it.
225 - Implement copies and stripes.
226 - Add history file to console.
227 - Each file on tape creates a JobMedia record. Peter has 4 million
228 files spread over 10000 tape files and four tapes. A restore takes
229 16 hours to build the restore list.
230 - Add and option to check if the file size changed during backup.
231 - Make sure SD deletes spool files on error exit.
232 - Delete old spool files when SD starts.
233 - When labeling tapes, if you enter 000026, Bacula uses
234 the tape index rather than the Volume name 000026.
235 - Add offline tape command to Bacula console.
237 Enter MediaId or Volume name: 32
238 Enter new Volume name: DLT-20Dec04

247 Label command failed for Volume DLT-20Dec04.
248 Do not forget to mount the drive!!!
249 - Bug: if a job is manually scheduled to run later, it does not appear
250 in any status report and cannot be cancelled.
252 ==== Keeping track of deleted files ====
253 My "trick" for keeping track of deletions is the following.
254 Assuming the user turns on this option, after all the files
255 have been backed up, but before the job has terminated, the
256 FD will make a pass through all the files and send their
257 names to the DIR (*exactly* the same as what a Verify job
258 currently does). This will probably be done at the same
259 time the files are being sent to the SD avoiding a second
260 pass. The DIR will then compare that to what is stored in
261 the catalog. Any files in the catalog but not in what the
262 FD sent will receive a catalog File entry that indicates
263 that at that point in time the file was deleted.
265 During a restore, any file initially picked up by some
266 backup (Full, ...) then subsequently having a File entry
267 marked "delete" will be removed from the tree, so will not
268 be restored. If a file with the same name is later OK it
269 will be inserted in the tree -- this already happens. All
270 will be consistent except for possible changes during the
273 Since I'm on the subject, some of you may be wondering what
274 the utility of the in memory tree is if you are going to
275 restore everything (at least it comes up from time to time
276 on the list). Well, it is still *very* useful because it
277 allows only the last item found for a particular filename
278 (full path) to be entered into the tree, and thus if a file
279 is backed up 10 times, only the last copy will be restored.
280 I recently (last Friday) restored a complete directory, and
281 the Full and all the Differential and Incremental backups
282 spanned 3 Volumes. The first Volume was not even mounted
283 because all the files had been updated and hence backed up
284 since the Full backup was made. In this case, the tree
285 saved me a *lot* of time.
287 Make sure this information is stored on the tape too so
288 that it can be restored directly from the tape.
290 Comments from Martin Simmons (I think they are all covered):
291 Ok, that should cover the basics. There are few issues though:
293 - Restore will depend on the catalog. I think it is better to include the
294 extra data in the backup as well, so it can be seen by bscan and bextract.
296 - I'm not sure if it will preserve multiple hard links to the same inode. Or
297 maybe adding or removing links will cause the data to be dumped again?
299 - I'm not sure if it will handle renamed directories. Possibly it will work
300 by dumping the whole tree under a renamed directory?
302 - It remains to be seen how the backup performance of the DIR's will be
303 affected when comparing the catalog for a large filesystem.
307 How about introducing a Type = MgmtPolicy job type? That job type would
308 be responsible for scanning the Bacula environment looking for specific
309 conditions, and submitting the appropriate jobs for implementing said
313 Name = "Migration-Policy"
315 Policy Selection Job Type = Migrate
316 Scope = "<keyword> <operator> <regexp>"
317 Threshold = "<keyword> <operator> <regexp>"
318 Job Template = <template-name>
321 Where <keyword> is any legal job keyword, <operator> is a comparison
322 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
323 appropriate regexp. I could see an argument for Scope and Threshold
324 being SQL queries if we want to support full flexibility. The
325 Migration-Policy job would then get scheduled as frequently as a site
326 felt necessary (suggested default: every 15 minutes).
331 Name = "Migration-Policy"
333 Policy Selection Job Type = Migration
335 Threshold = "Migration Selection Type = LowestUtil"
336 Job Template = "MigrationTemplate"
339 would select all pools for examination and generate a job based on
340 MigrationTemplate to automatically select the volume with the lowest
341 usage and migrate it's contents to the nextpool defined for that pool.
343 This policy abstraction would be really handy for adjusting the behavior
344 of Bacula according to site-selectable criteria (one thing that pops
345 into mind is Amanda's ability to automatically adjust backup levels
346 depending on various criteria).
352 - Add Pool/Storage override regression test.
353 - Add delete JobId to regression.
354 - Add a regression test for dbcheck.
355 - New test to add bscan to four-concurrent-jobs regression,
356 i.e. after the four-concurrent jobs zap the
357 database as is done in the bscan-test, then use bscan to
358 restore the database, do a restore and compare with the

379 === From Carsten Menke <bootsy52@gmx.net>
381 Following is a list of what I think in the situations where I'm faced with,
382 could be a usefull enhancement to bacula, which I'm certain other users will
383 benefit from as well.
385 1. NextJob/NextJobs Directive within a Job Resource in the form of
386 NextJobs = job1,job2.
389 I currently solved the problem with running multiple jobs each after each
390 by setting the Max Wait Time for a job to 8 hours, and give
391 the jobs different Priorities. However, there scenarios where
392 1 Job is directly depending on another job, so if the former job fails,
393 the job after it needn't to be run
394 while maybe other jobs should run despite of that
397 A Backup Job and a Verify job, if the backup job fails there is no need to run
398 the verify job, as the backup job already failed. However, one may like
399 to backup the Catalog to disk despite of that the main backup job failed.
402 I see that this is related to the Event Handlers which are on the ToDo
403 list, also it is maybe a good idea to check for the return value and
404 execute different actions based on the return value
407 3. offline capability to bconsole
410 Currently I use a script which I execute within the last Job via the
411 RunAfterJob Directive, to release and eject the tape.
412 So I have to call bconsole "release=Storage-Name" and afterwards
413 mt -f /dev/nst0 eject to get the tape out.
415 If I have multiple Storage Devices, than these may not be /dev/nst0 and
416 I have to modify the script or call it with parameters etc.
417 This would actually not be needed, as everything is already defined
418 in bacula-sd.conf and if I can invoke bconsole with the
419 storage name via $1 in the script than I'm done and information is
422 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
426 For the reason mentioned in 3. to have the ability to call a
427 script with /scripts/foobar %s and in the script use $1
428 to pass the Storage Name to bconsole
430 5. Setting Volume State within a Job Resource
433 Instead of using "Maximum Volume Jobs" in the Pool Resource,
434 I would have the possibilty to define
435 in a Job Resource that after this certain job is run, the Volume State
436 should be set to "Volume State = Used", this give more flexibility (IMHO).
438 6. Localization of Bacula Messages
441 Unfortunatley many,many people I work with don't speak english very well.
442 So if at least the Reporting messages would be localized then they
443 would understand that they have to change the tape,etc. etc.
445 I volunteer to do the german translations, and if I can convince my wife also
446 french and Morre (western african language).
448 7. OK, this is evil, probably bound to security risks and maybe not possible
449 due to the design of bacula.
451 Implementation of Backtics ( `command` ) for shell comand execution to
452 the "Label Format" Directive.
456 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
457 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
458 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
459 the localized name for the day of the week appended to the
460 format string. Then I have the tape labeled automatically with weekday
461 name in the correct language.
463 - Yes, that is surely the case. I probably should turn those into Warning
464 errors. In addition, you just made me think that it might not be bad to
465 add an option to check the file size after backing up the file and
466 report if it changes. This would be done as an option because it would
469 Kern, good idea. If you do do that, mention in the output: file
470 shrunk, or file expanded, just to make it obvious to the user
471 (without having to the refer to file size), just how the file size
474 Would this option be for all file, or just one file? Or a fileset?
475 - Make output from status use html table tags for nicely
476 presenting in a browser.
477 - Can one write tapes faster with 8192 byte block sizes?
478 - Document security problems with the same password for everyone in
479 rpm and Win32 releases.
480 - Browse generations of files.
481 - I've seen an error when my catalog's File table fills up. I
482 then have to recreate the File table with a larger maximum row
483 size. Relevant information is at
484 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
485 "Installing and Configuring MySQL" chapter should talk a bit
486 about this potential problem, and recommend a solution.
487 - For Solaris must use POSIX awk.
488 - Want speed of writing to tape while despooling.
489 - Supported autochanger:
497 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
498 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
499 - Add regex from http://www.pcre.org to Bacula for Win32.
500 - Use only shell tools no make in CDROM package.
501 - Include within include does it work?
502 - Implement a Pool of type Cleaning?
503 - Implement VolReadTime and VolWriteTime in SD
504 - Modify Backing up Your Database to include a bootstrap file.
505 - Think about making certain database errors fatal.
506 - Look at correcting the time jump in the scheduler for daylight
507 savings time changes.
508 - Add a "real" timer to network connections.
509 - Promote to Full = Time period
510 - Check dates entered by user for correctness (month/day/... ranges)
511 - Compress restore Volume listing by date and first file.
512 - Look at patches/bacula_db.b2z postgresql that loops during restore.
514 - Perhaps add read/write programs and/or plugins to FileSets.
515 - How to handle backing up portables ...
516 - Add some sort of guaranteed Interval for upgrading jobs.
517 - Can we write the state file after every job terminates? On Win32
518 the system crashes and the state file is not updated.
521 Documentation to do: (any release a little bit at a time)
522 - Doc to do unmount before removing magazine.
523 - Alternative to static linking "ldd prog" save all binaries listed,
524 restore them and point LD_LIBRARY_PATH to them.
525 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
526 - Document query file format.
527 - Add more documentation for bsr files.
528 - Document problems with Verify and pruning.
529 - Document how to use multiple databases.
530 - VXA drives have a "cleaning required"
531 indicator, but Exabyte recommends preventive cleaning after every 75
534 In this context, it should be noted that Exabyte has a command-line
535 vxatool utility available for free download. (The current version is
536 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
537 test the drive, unload tapes, change drive settings, flash new firmware,
539 Of particular interest in this context is that vxatool <device> -i will
540 report, among other details, the time since last cleaning in tape motion
541 minutes. This information can be retrieved (and settings changed, for
542 that matter) through the generic-SCSI device even when Bacula has the
543 regular tape device locked. (Needless to say, I don't recommend
544 changing tape settings while a job is running.)
545 - Lookup HP cleaning recommendations.
546 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
547 - Document doing table repair
550 ===================================
551 - Add macro expansions in JobDefs.
552 Run Before Job = "SomeFile %{Level} %{Client}"
553 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
554 - Use non-blocking network I/O but if no data is available, use
556 - Use gather write() for network I/O.
557 - Autorestart on crash.
558 - Add bandwidth limiting.
559 - Add acks every once and a while from the SD to keep
560 the line from timing out.
561 - When an error in input occurs and conio beeps, you can back
562 up through the prompt.
563 - Detect fixed tape block mode during positioning by looking at
564 block numbers in btape "test". Possibly adjust in Bacula.
565 - Fix list volumes to output volume retention in some other
566 units, perhaps via a directive.
567 - If opening a tape in read/write mode fails attempt to open
568 it in read-only mode, and mark the tape for read only.
569 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
570 with multiple priorities.
571 - If you use restore replace=never, the directory attributes for
572 non-existent directories will not be restored properly.
574 - see lzma401.zip in others directory for new compression
576 - Minimal autochanger handling in Bacula and in btape.
577 - Look into how tar does not save sockets and the possiblity of
578 not saving them in Bacula (Martin Simmons reported this).
579 - Fix restore jobs so that multiple jobs can run if they
580 are not using the same tape(s).
581 - Allow the user to select JobType for manual pruning/purging.
582 - bscan does not put first of two volumes back with all info in
584 - Implement the FreeBSD nodump flag in chflags.
585 - Figure out how to make named console messages go only to that
586 console and to the non-restricted console (new console class?).
587 - Make restricted console prompt for password if *ask* is set or
588 perhaps if password is undefined.
589 - Implement "from ISO-date/time every x hours/days/weeks/months" in
592 ==== from Marc Schoechlin
593 - the help-command should be more verbose
594 (it should explain the paramters of the different
596 -> its time-comsuming to consult the manual anytime
597 you need a special parameter
598 -> maybe its more easy to maintain this, if the
599 descriptions of that commands are outsourced to
601 - the cd-command should allow complete paths
602 i.e. cd /foo/bar/foo/bar
603 -> if a customer mails me the path to a certain file,
604 its faster to enter the specified directory
605 - if the password is not configured in bconsole.conf
606 you should be asked for it.
607 -> sometimes you like to do restore on a customer-machine
608 which shouldnt know the password for bacula.
609 -> adding the password to the file favours admins
610 to forget to remove the password after usage
612 the protection of that file is less important
613 - long-listed-output of commands should be scrollable
614 like the unix more/less-command does
615 -> if someone runs 200 and more machines, the lists could
616 be a little long and complex
617 - command-output should be shown column by column
618 to reduce scrolling and to increase clarity
620 - lsmark should list the selected files with full
622 - wildcards for selecting and file and directories would be nice
623 - any actions should be interuptable with STRG+C
624 - command-expansion would be pretty cool
626 - When the replace Never option is set, new directory permissions
627 are not restored. See bug 213. To fix this requires creating a
628 list of newly restored directories so that those directory
629 permissions *can* be restored.
630 - Compaction of Disk space by "migrating" Volumes that have pruned
631 Jobs (what criteria? size, #jobs, time).
632 - Add prune all command
633 - Document fact that purge can destroy a part of a restore by purging
634 one volume while others remain valid -- perhaps mark Jobs.
635 - Add multiple-media-types.txt
636 - look at mxt-changer.html
637 - Make ? do a help command (no return needed).
638 - Implement restore directory.
639 - Document streams and how to implement them.
640 - Try not to re-backup a file if a new hard link is added.
641 - Add feature to backup hard links only, but not the data.
642 - Fix stream handling to be simpler.
643 - Add Priority and Bootstrap to Run a Job.
644 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
646 - Remove View FileSet button from Run a Job dialog.
647 - Handle prompt for restore job at end of Restore command.
648 - Add display of total selected files to Restore window.
649 - Add tree pane to left of window.
650 - Add progress meter.
651 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
652 - Document writing to a CD/DVD with Bacula.
653 - Add a "base" package to the window installer for pthreadsVCE.dll
654 which is needed by all packages.
655 - Add message to user to check for fixed block size when the forward
656 space test fails in btape.
657 - When unmarking a directory check if all files below are unmarked and
658 then remove the + flag -- in the restore tree.
659 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
660 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
661 - Revisit the question of multiple Volumes (disk) on a single device.
662 - Add a block copy option to bcopy.
663 - Investigate adding Mac Resource Forks.
664 - Finish work on Gnome restore GUI.
665 - Fix "llist jobid=xx" where no fileset or client exists.
666 - For each job type (Admin, Restore, ...) require only the really necessary
667 fields.- Pass Director resource name as an option to the Console.
668 - Add a "batch" mode to the Console (no unsolicited queries, ...).
669 - Add a .list all files in the restore tree (probably also a list all files)
670 Do both a long and short form.
671 - Allow browsing the catalog to see all versions of a file (with
672 stat data on each file).
673 - Restore attributes of directory if replace=never set but directory
675 - Use SHA1 on authentication if possible.
676 - See comtest-xxx.zip for Windows code to talk to USB.
677 - Add John's appended files:
678 Appended = { /files/server/logs/http/*log }
679 and such files would be treated as follows.On a FULL backup, they would
680 be backed up like any other file.On an INCREMENTAL backup, where a
681 previous INCREMENTAL or FULL was already in thecatalogue and the length
682 of the file wasgreater than the length of the last backup, only thedata
683 added since the last backup will be dumped.On an INCREMENTAL backup, if
684 the length of the file is less than thelength of the file with the same
685 name last backed up, the completefile is dumped.On Windows systems, with
686 creation date of files, we can be evensmarter about this and not count
687 entirely upon the length.On a restore, the full and all incrementals
688 since it will beapplied in sequence to restore the file.
689 - Check new HAVE_WIN32 open bits.
690 - Check if the tape has moved before writing.
691 - Handling removable disks -- see below:
692 - Keep track of tape use time, and report when cleaning is necessary.
693 - Add FromClient and ToClient keywords on restore command (or
694 BackupClient RestoreClient).
695 - Implement a JobSet, which groups any number of jobs. If the
696 JobSet is started, all the jobs are started together.
697 Allow Pool, Level, and Schedule overrides.
698 - Enhance cancel to timeout BSOCK packets after a specific delay.
699 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
700 ua_status.!!! Thanks to Alan Brown for this tip.
701 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
702 correctly for multiple simultaneous jobs.
703 - Correct code so that FileSet MD5 is calculated for < and | filename
705 - Implement the Media record flag that indicates that the Volume does disk
707 - Implement VolAddr, which is used when Volume is addressed like a disk,
708 and form it from VolFile and VolBlock.
709 - Make multiple restore jobs for multiple media types specifying
710 the proper storage type.
711 - Fix fast block rejection (stored/read_record.c:118). It passes a null
712 pointer (rec) to try_repositioning().
713 - Look at extracting Win data from BackupRead.
714 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
715 which would take precidence over the Catalog "JobRetention".
716 - Implement Label Format in Add and Label console commands.
717 - Possibly up network buffers to 65K. Put on variable.
718 - Put email tape request delays on one or more variables. User wants
719 to cancel the job after a certain time interval. Maximum Mount Wait?
720 - Job, Client, Device, Pool, or Volume?
721 Is it possible to make this a directive which is *optional* in multiple
722 resources, like Level? If so, I think I'd make it an optional directive
723 in Job, Client, and Pool, with precedence such that Job overrides Client
724 which in turn overrides Pool.
726 - New Storage specifications:
727 - Want to write to multiple storage devices simultaneously
728 - Want to write to multiple storage devices sequentially (in one job)
729 - Want to read/write simultaneously
730 - Key is MediaType -- it must match
732 Passed to SD as a sort of BSR record called Storage Specification
736 MediaType -> Next MediaType
738 Device -> Next Device
740 Allow multiple Storage specifications
748 Allow Multiple Pool specifications (note, Pool currently
750 Allow Multiple MediaType specifications in Dir conf
751 Allow Multiple Device specifications in Dir conf
752 Perhaps keep this in a single SSR
753 Tie a Volume to a specific device by using a MediaType that
754 is contained in only one device.
755 In SD allow Device to have Multiple MediaTypes
757 - Ideas from Jerry Scharf:
758 First let's point out some big pluses that bacula has for this
760 more importantly it's active. Thank you so much for that
761 even more important, it's not flaky
762 it has an open access catalog, opening many possibilities
763 it's pushing toward heterogeneous systems capability
765 Macintosh file client
766 macs are an interesting niche, but I fear a server is a rathole
767 working bare iron recovery for windows
768 the option for inc/diff backups not reset on fileset revision
769 a) use both change and inode update time against base time
770 b) do the full catalog check (expensive but accurate)
771 sizing guide (how much system is needed to back up N systems/files)
772 consultants on using bacula in building a disaster recovery system
774 or how to get at fancy things that one could do with bacula
775 logwatch code for bacula logs (or similar)
776 linux distro inclusion of bacula (brings good and bad, but necessary)
777 win2k/XP server capability (icky but you asked)
778 support for Oracle database ??
780 - Look at adding SQL server and Exchange support for Windows.
781 - Make dev->file and dev->block_num signed integers so that -1 can
782 be an invalid value which happens with BSR.
783 - Create VolAddr for disk files in place of VolFile and VolBlock. This
784 is needed to properly specify ranges.
785 - Add progress of files/bytes to SD and FD.
786 - Print warning message if FileId > 4 billion
787 - do a "messages" before the first prompt in Console
788 - Client does not show busy during Estimate command.
789 - Implement Console mtx commands.
790 - Implement a Mount Command and an Unmount Command where
791 the users could specify a system command to be performed
792 to do the mount, after which Bacula could attempt to
793 read the device. This is for Removeable media such as a CDROM.
794 - Most likely, this mount command would be invoked explicitly
795 by the user using the current Console "mount" and "unmount"
796 commands -- the Storage Daemon would do the right thing
797 depending on the exact nature of the device.
798 - As with tape drives, when Bacula wanted a new removable
799 disk mounted, it would unmount the old one, and send a message
800 to the user, who would then use "mount" as described above
801 once he had actually inserted the disk.
802 - Implement dump/print label to UA
803 - Spool to disk only when the tape is full, then when a tape is hung move
805 - bextract is sending everything to the log file ****FIXME****
806 - Allow multiple Storage specifications (or multiple names on
807 a single Storage specification) in the Job record. Thus a job
808 can be backed up to a number of storage devices.
809 - Implement some way for the File daemon to contact the Director
810 to start a job or pass its DHCP obtained IP number.
811 - Implement a query tape prompt/replace feature for a console
812 - Copy console @ code to gnome2-console
813 - Make AES the only encryption algorithm see
814 http://csrc.nist.gov/CryptoToolkit/aes/). It's
815 an officially adopted standard, has survived peer
816 review, and provides keys up to 256 bits.
817 - Take a careful look at SetACL http://setacl.sourceforge.net
818 - Make tree walk routines like cd, ls, ... more user friendly
819 by handling spaces better.
820 - Make sure that Bacula rechecks the tape after the 20 min wait.
821 - Set IO_NOWAIT on Bacula TCP/IP packets.
822 - Try doing a raw partition backup and restore by mounting a
825 Yes, it would allow to highly automatic the request for new tapes. If a
826 tape is empty, bacula reads the barcodes (native or simulated), and if
827 an unused tape is found, it runs the label command with all the
828 necessary parameters.
830 By the way can bacula automatically "move" an empty/purged volume say
831 in the "short" pool to the "long" pool if this pool runs out of volume
833 - What to do about "list files job=xxx".
834 - Get and test MySQL 4.0
835 - Look at how fuser works and /proc/PID/fd that is how Nic found the
836 file descriptor leak in Bacula.
837 - Implement WrapCounters in Counters.
838 - Add heartbeat from FD to SD if hb interval expires.
839 - Can we dynamically change FileSets?
840 - If pool specified to label command and Label Format is specified,
841 automatically generate the Volume name.
842 - Why can't SQL do the filename sort for restore?
843 - Add ExhautiveRestoreSearch
844 - Look at the possibility of loading only the necessary
845 data into the restore tree (i.e. do it one directory at a
846 time as the user walks through the tree).
847 - Possibly use the hash code if the user selects all for a restore command.
848 - Fix "restore all" to bypass building the tree.
849 - Prohibit backing up archive device (findlib/find_one.c:128)
850 - Implement Release Device in the Job resource to unmount a drive.
851 - Implement Acquire Device in the Job resource to mount a drive,
852 be sure this works with admin jobs so that the user can get
853 prompted to insert the correct tape. Possibly some way to say to
854 run the job but don't save the files.
855 - Make things like list where a file is saved case independent for
858 - Use autochanger to handle multiple devices.
859 - On Windows with very long path names, it may be impossible to create
860 a file (and thus restore it) because the total length is too long.
861 We must cd into the directory then create the file without the
863 - Implement a Recycle command
864 - Test a second language e.g. french.
865 - Start working on Base jobs.
866 - Implement UnsavedFiles DB record.
867 - From Phil Stracchino:
868 It would probably be a per-client option, and would be called
869 something like, say, "Automatically purge obsoleted jobs". What it
870 would do is, when you successfully complete a Differential backup of a
871 client, it would automatically purge all Incremental backups for that
872 client that are rendered redundant by that Differential. Likewise,
873 when a Full backup on a client completed, it would automatically purge
874 all Differential and Incremental jobs obsoleted by that Full backup.
875 This would let people minimize the number of tapes they're keeping on
876 hand without having to master the art of retention times.
877 - When doing a Backup send all attributes back to the Director, who
878 would then figure out what files have been deleted.
879 - Currently in mount.c:236 the SD simply creates a Volume. It should have
880 explicit permission to do so. It should also mark the tape in error
881 if there is an error.
882 - Cancel waiting for Client connect in SD if FD goes away.
884 - Implement timeout in response() when it should come quickly.
885 - Implement a Slot priority (loaded/not loaded).
886 - Implement "vacation" Incremental only saves.
887 - Implement create "FileSet"?
888 - Add prefixlinks to where or not where absolute links to FD.
889 - Issue message to mount a new tape before the rewind.
890 - Simplified client job initiation for portables.
891 - If SD cannot open a drive, make it periodically retry.
892 - Add more of the config info to the tape label.
894 - If tape is marked read-only, then try opening it read-only rather than
895 failing, and remember that it cannot be written.
896 - Refine SD waiting output:
897 Device is being positioned
898 > Device is being positioned for append
899 > Device is being positioned to file x
901 - Figure out some way to estimate output size and to avoid splitting
902 a backup across two Volumes -- this could be useful for writing CDROMs
903 where you really prefer not to have it split -- not serious.
904 - Have SD compute MD5 or SHA1 and compare to what FD computes.
905 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
906 actual data on the Volume and compare it.
907 - Implement Bacula plugins -- design API
908 - Make bcopy read through bad tape records.
909 - Program files (i.e. execute a program to read/write files).
910 Pass read date of last backup, size of file last time.
911 - Add Signature type to File DB record.
912 - CD into subdirectory when open()ing files for backup to
913 speed up things. Test with testfind().
914 - Priority job to go to top of list.
915 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
916 - Implement some way for the Console to dynamically create a job.
917 - Solaris -I on tar for include list
918 - Need a verbose mode in restore, perhaps to bsr.
919 - bscan without -v is too quiet -- perhaps show jobs.
920 - Add code to reject whole blocks if not wanted on restore.
921 - Check if we can increase Bacula FD priorty in Win2000
922 - Make sure the MaxVolFiles is fully implemented in SD
923 - Check if both CatalogFiles and UseCatalog are set to SD.
924 - Possibly add email to Watchdog if drive is unmounted too
925 long and a job is waiting on the drive.
926 - After unmount, if restore job started, ask to mount.
927 - Add UA rc and history files.
928 - put termcap (used by console) in ./configure and
929 allow -with-termcap-dir.
930 - Fix Autoprune for Volumes to respect need for full save.
931 - Compare tape to Client files (attributes, or attributes and data)
932 - Make all database Ids 64 bit.
933 - Allow console commands to detach or run in background.
934 - Fix status delay on storage daemon during rewind.
935 - Add SD message variables to control operator wait time
936 - Maximum Operator Wait
937 - Minimum Message Interval
938 - Maximum Message Interval
939 - Send Operator message when cannot read tape label.
940 - Verify level=Volume (scan only), level=Data (compare of data to file).
941 Verify level=Catalog, level=InitCatalog
943 - Add keyword search to show command in Console.
944 - Events : tape has more than xxx bytes.
945 - Complete code in Bacula Resources -- this will permit
946 reading a new config file at any time.
947 - Handle ctl-c in Console
948 - Implement script driven addition of File daemon to config files.
949 - Think about how to make Bacula work better with File (non-tape) archives.
950 - Write Unix emulator for Windows.
951 - Put memory utilization in Status output of each daemon
952 if full status requested or if some level of debug on.
953 - Make database type selectable by .conf files i.e. at runtime
954 - Set flag for uname -a. Add to Volume label.
955 - Restore files modified after date
956 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
957 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
958 - Timout a job or terminate if link goes down, or reopen link and query.
959 - Concept of precious tapes (cannot be reused).
960 - Make bcopy copy with a single tape drive.
961 - Permit changing ownership during restore.

975 - Autolabel should be specified by DIR instead of SD.
978 - AutoScan (check checksum of tape)
979 - Format command = "format /dev/nst0"
983 - Seek resolution (usually corresponds to buffer size)
984 - EODErrorCode=ENOSPC or code
985 - Partial Read error code
986 - Partial write error code
987 - Nonformatted read error
988 - Nonformatted write error
989 - WriteProtected error
993 - IgnoreCloseErrors=yes
1003 - FD sends unsaved file list to Director at end of job (see
1005 - File daemon should build list of files skipped, and then
1006 at end of save retry and report any errors.
1007 - Write a Storage daemon that uses pipes and
1008 standard Unix programs to write to the tape.
1010 - Need something that monitors the JCR queue and
1011 times out jobs by asking the deamons where they are.
1012 - Enhance Jmsg code to permit buffering and saving to disk.
1013 - device driver = "xxxx" for drives.
1014 - Verify from Volume
1015 - Ensure that /dev/null works
1016 - Need report class for messages. Perhaps
1017 report resource where report=group of messages
1018 - enhance scan_attrib and rename scan_jobtype, and
1019 fill in code for "since" option
1020 - Director needs a time after which the report status is sent
1021 anyway -- or better yet, a retry time for the job.
1022 - Don't reschedule a job if previous incarnation is still running.
1023 - Some way to automatically backup everything is needed????
1024 - Need a structure for pending actions:
1026 - termination status (part of buffered msgs?)
1028 Read, Write, Clean, Delete
1029 - Login to Bacula; Bacula users with different permissions:
1030 owner, group, user, quotas
1031 - Store info on each file system type (probably in the job header on tape.
1032 This could be the output of df; or perhaps some sort of /etc/mtab record.
1034 ========= ideas ===============
1035 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1036 To: <kern@sibbald.com>
1037 Subject: RE: [Bacula-users] future large programming jobs
1038 Date: Thu, 26 Feb 2004 11:34:54 -0600
1040 I noticed the subject thread and thought I would offer the following
1041 merely as sources of ideas, i.e. something to think about, not even as
1042 strong as a request. In my former life (before retiring) I often
1043 dealt with backups and storage management issues/products as a
1044 developer and as a consultant. I am currently migrating my personal
1045 network from amanda to bacula specifically because of the ability to
1046 cross media boundaries during storing backups.
1047 Are you familiar with the commercial product called ADSM (I think IBM
1048 now sells it under the Tivoli label)? It has a couple of interesting
1049 ideas that may apply to the following topics.
1051 1. Migration: Consider that when you need to restore a system, there
1052 may be pressure to hurry. If all the information for a single client
1053 can eventually end up on the same media (and in chronological order),
1054 the restore is facillitated by not having to search past information
1055 from other clients. ADSM has the concept of "client affinity" that
1056 may be associated with it's storage pools. It seems to me that this
1057 concept (as an optional feature) might fit in your architecture for
1060 ADSM also has the concept of defining one or more storage pools as
1061 "copy pools" (almost mirrors, but only in the sense of contents).
1062 These pools provide the ability to have duplicte data stored both
1063 onsite and offsite. The copy process can be scheduled to be handled
1064 by their storage manager during periods when there is no backup
1065 activity. Again, the migration process might be a place to consider
1066 implementing something like this.
1069 > It strikes me that it would be very nice to be able to do things
1071 > have the Job(s) backing up the machines run, and once they have all

1077 > mechanism described below would probably make it very easy.
1079 This is the goal. In the first step (before events), you simply
1081 the Migration to tape later.
1083 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1084 the database. Once a file (unique by path and metadata such as dates,
1085 size, ownership, etc.) is in a copy pool, no more copies are made. In
1086 other words, when you start ADSM, it begins like your concept of a
1087 base job. After that it is in the "incremental" mode. You can
1088 configure the number of "generations" of files to be retained, plus a
1089 retention date after which even old generations are purged. The
1090 database tracks the contents of media and projects the percentage of
1091 each volume that is valid. When the valid content of a volume drops
1092 below a configured percentage, the valid data are migrated to another
1093 volume and the old volume is marked as empty. Note, this requires
1094 ADSM to have an idea of the contents of a client, i.e. marking the
1095 database when an existing file was deleted, but this would solve your
1096 issue of restoring a client without restoring deleted files.
1098 This is pretty far from what bacula now does, but if you are going to
1099 rip things up for Base jobs,.....
1100 Also, the benefits of this are huge for very large shops, especially
1101 with media robots, but are a pain for shops with manual media
1105 > Base jobs sound pretty useful, but I'm not dying for them.
1107 Nobody is dying for them, but when you see what it does, you will die
1110 3. Restoring deleted files: Since I think my comments in (2) above
1111 have low probability of implementation, I'll also suggest that you
1112 could approach the issue of deleted files by a mechanism of having the
1113 fd report to the dir, a list of all files on the client for every
1114 backup job. The dir could note in the database entry for each file
1115 the date that the file was seen. Then if a restore as of date X takes
1116 place, only files that exist from before X until after X would be
1117 restored. Probably the major cost here is the extra date container in
1118 each row of the files table.
1120 Thanks for "listening". I hope some of this helps. If you want to
1121 contact me, please send me an email - I read some but not all of the
1122 mailing list traffic and might miss a reply there.
1124 Please accept my compliments for bacula. It is doing a great job for
1125 me!! I sympathize with you in the need to wrestle with excelence in
1126 execution vs. excelence in feature inclusion.
1131 ==============================
1134 - Design at hierarchial storage for Bacula. Migration and Clone.
1135 - Implement FSM (File System Modules).
1136 - Audit M_ error codes to ensure they are correct and consistent.
1137 - Add variable break characters to lex analyzer.
1138 Either a bit mask or a string of chars so that
1139 the caller can change the break characters.
1140 - Make a single T_BREAK to replace T_COMMA, etc.
1141 - Ensure that File daemon and Storage daemon can
1142 continue a save if the Director goes down (this
1143 is NOT currently the case). Must detect socket error,
1144 buffer messages for later.
1145 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1146 - Add ability to backup to two Storage devices (two SD sessions) at
1147 the same time -- e.g. onsite, offsite.
1148 - Add the ability to consolidate old backup sets (basically do a restore
1149 to tape and appropriately update the catalog). Compress Volume sets.
1150 Might need to spool via file is only one drive is available.
1151 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1152 someway to do so with every volume that has less than x% valid

1170 ======================================================
1172 It is somewhat like a Full save becomes an incremental since
1173 the Base job (or jobs) plus other non-base files.
1175 - A Base backup is same as Full backup, just different type.
1176 - New BaseFiles table that contains:
1178 BaseJobId - Base JobId referenced for this FileId (needed ???)
1179 JobId - JobId currently running
1180 FileId - File not backed up, exists in Base Job
1181 FileIndex - FileIndex from Base Job.
1182 i.e. for each base file that exists but is not saved because
1183 it has not changed, the File daemon sends the JobId, BaseId,
1184 FileId, FileIndex back to the Director who creates the DB entry.
1185 - To initiate a Base save, the Director sends the FD
1186 the FileId, and full filename for each file in the Base.
1187 - When the FD finds a Base file, he requests the Director to
1188 send him the full File entry (stat packet plus MD5), or
1189 conversely, the FD sends it to the Director and the Director
1190 says yes or no. This can be quite rapid if the FileId is kept
1191 by the FD for each Base Filename.
1192 - It is probably better to have the comparison done by the FD
1193 despite the fact that the File entry must be sent across the
1195 - An alternative would be to send the FD the whole File entry
1196 from the start. The disadvantage is that it requires a lot of
1197 space. The advantage is that it requires less communications
1199 - The Job record must be updated to indicate that one or more
1201 - At end of Job, FD returns:
1202 1. Count of base files/bytes not written to tape (i.e. matches)
1203 2. Count of base file that were saved i.e. had changed.
1204 - No tape record would be written for a Base file that matches, in the
1205 same way that no tape record is written for Incremental jobs where
1206 the file is not saved because it is unchanged.
1207 - On a restore, all the Base file records must explicitly be
1208 found from the BaseFile tape. I.e. for each Full save that is marked
1209 to have one or more Base Jobs, search the BaseFile for all occurrences
1211 - An optimization might be to make the BaseFile have:
1217 This would avoid the need to explicitly fetch each File record for
1218 the Base job. The Base Job record will be fetched to get the
1219 VolSessionId and VolSessionTime.
1220 =========================================================
1223 ==========================================================
1225 For each Incremental job that is run, there may be files that
1226 were found but not saved because they were locked (this applies
1227 only to Windows). Such a system could send back to the Director
1228 a list of Unsaved files.
1230 - New UnSavedFiles table that contains:
1234 - Then in the next Incremental job, the list of Unsaved Files will be
1235 feed to the FD, who will ensure that they are explicitly chosen even
1236 if standard date/time check would not have selected them.

1281 There needs to be a table of drive # to devices somewhere - If there are
1282 multiple changers or drives there may not be a 1:1 correspondance between
1283 changer drive number and system device name - and depending on the way the
1284 drives are hooked up to scsi busses, they may not be linearly numbered
1285 from an offset point either.something like
1287 Autochanger drives = 2
1288 Autochanger drive 0 = /dev/nst1
1289 Autochanger drive 1 = /dev/nst2
1290 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1291 times, not just for multidrive changers. For a 1 drive changer, that's
1297 MTX's manpage (1.2.15):
1298 unload [<slotnum>] [ <drivenum> ]
1299 Unloads media from drive <drivenum> into slot
1300 <slotnum>. If <drivenum> is omitted, defaults to
1301 drive 0 (as do all commands). If <slotnum> is
1302 omitted, defaults to the slot that the drive was
1303 loaded from. Note that there's currently no way
1304 to say 'unload drive 1's media to the slot it
1305 came from', other than to explicitly use that
1306 slot number as the destination.AB

1344 Handling removable disks
1346 From: Karl Cunningham <karlc@keckec.com>
1348 My backups are only to hard disk these days, in removable bays. This is my
1349 idea of how a backup to hard disk would work more smoothly. Some of these
1350 things Bacula does already, but I mention them for completeness. If others
1351 have better ways to do this, I'd like to hear about it.
1353 1. Accommodate several disks, rotated similar to how tapes are. Identified
1354 by partition volume ID or perhaps by the name of a subdirectory.
1355 2. Abort & notify the admin if the wrong disk is in the bay.
1356 3. Write backups to different subdirectories for each machine to be backed
1358 4. Volumes (files) get created as needed in the proper subdirectory, one
1360 5. When a disk is recycled, remove or zero all old backup files. This is
1361 important as the disk being recycled may be close to full. This may be
1362 better done manually since the backup files for many machines may be
1363 scattered in many subdirectories.
1368 - Make sure that all do_prompt() calls in Dir check for
1369 -1 (error) and -2 (cancel) returns.
1370 - Fix foreach_jcr() to have free_jcr() inside next().
1371 jcr=jcr_walk_start();
1372 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1375 - A Volume taken from Scratch should take on the retention period
1377 - Correct doc for Maximum Changer Wait (and others) accepting only
1379 - Implement status that shows why a job is being held in reserve, or
1380 rather why none of the drives are suitable.
1381 - Implement a way to disable a drive (so you can use the second
1382 drive of an autochanger, and the first one will not be used or
1384 - Make sure Maximum Volumes is respected in Pools when adding
1385 Volumes (e.g. when pulling a Scratch volume).
1386 - Keep same dcr when switching device ...
1387 - Implement code that makes the Dir aware that a drive is an
1388 autochanger (so the user doesn't need to use the Autochanger = yes
1390 - Make catalog respect ACL.
1391 - Add recycle count to Media record.
1392 - Add initial write date to Media record.
1393 - Fix store_yesno to be store_bitmask.
