12 - Does WildFile match against full name? Doc.
13 - %d and %v only valid on Director, not for ClientRunBefore/After.
14 - During tests with the 260 char fix code, I found one problem:
15 if the system "sees" a long path once, it seems to forget it's
16 working drive (e.g. c:\), which will lead to a problem during
17 the next job (create bootstrap file will fail). Here is the
18 workaround: specify absolute working and pid directory in
19 bacula-fd.conf (e.g. c:\bacula\working instead of

59 > storage="File2" before="2007-02-05 23:05:04" do? (Dirk)
61 - Implement update jobid=
62 - Mention Eric and Marc's work + Marc's doc.
64 - When Pool specifies Storage command override does not work.
65 - Implement wait_for_sysop() message display in wait_for_device(), which
66 now prints warnings too often.
68 - Ensure that each device in an Autochanger has a different
70 - Add Catalog = to Pool resource so that pools will exist
71 in only one catalog -- currently Pools are "global".
72 - Look at sg_logs -a /dev/sg0 for getting soft errors.
73 - btape "test" command with Offline on Unmount = yes

162 writing the daemon message, when Dir dropped to bacula:bacula
163 - Look at zlib 32 => 64 problems.
164 - Possibly turn on St. Bernard code.

174 better machine-readable output like "Ok" or "Error busy"
175 .move eject device=xxx toslot=yyy the same as above, but with a new

188 - It appears to me that you have run into some sort of race
189 condition where two threads want to use the same Volume and they
190 were both given access. Normally that is no problem. However,
191 one thread wanted the particular Volume in drive 0, but it was
192 loaded into drive 1 so it decided to unload it from drive 1 and
193 then loaded it into drive 0, while the second thread went on
194 thinking that the Volume could be used in drive 1 not realizing
195 that in between time, it was loaded in drive 0.
196 I'll look at the code to see if there is some way we can avoid
197 this kind of problem. Probably the best solution is to make the
198 first thread simply start using the Volume in drive 1 rather than
199 transferring it to drive 0.
200 - Fix re-read of last block to check if job has actually written
201 a block, and check if block was written by a different job
202 (i.e. multiple simultaneous jobs writing).
203 - Figure out how to configure query.sql. Suggestion to use m4:
204 == changequote.m4 ===
205 changequote(`[',`]')dnl
206 ==== query.sql.in ===
207 :List next 20 volumes to expire
209 Pool.Name AS PoolName,
214 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
216 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
220 ON Media.PoolId=Pool.PoolId
221 WHERE Media.LastWritten>0
225 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
227 The problem is that it requires m4, which is not present on all machines
229 - Given all the problems with FIFOs, I think the solution is to do something a
230 little different, though I will look at the code and see if there is not some
231 simple solution (i.e. some bug that was introduced). What might be a better
232 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
233 write data to a program rather than the FIFO. For example, suppose you
238 Then, I could imagine if you backup and restore this file with a direct
239 reference as is currently done for fifos, instead, during backup Bacula will
242 /home/kern/my-fifo.backup
244 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
247 /home/kern/my-fifo.restore
249 and send the data backed up to stdout. These programs can either be an
250 executable or a shell script and they need only read/write to stdin/stdout.
252 I think this would give a lot of flexibility to the user without making any
253 significant changes to Bacula.
258 select FilenameId from Filename where Name='';

270 === Migration from David ===
271 What I'd like to see:
274 Name = "<poolname>-migrate"
278 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
279 Client | PoolResidence | Volume | JobName | SQLquery
280 Migration Selection Pattern = "regexp"
281 Next Pool = <override>
284 There should be no need for a Level (migration is always Full, since you
285 don't calculate differential/incremental differences for migration),
286 Storage should be determined by the volume types in the pool, and Client
287 is really a selection issue. Migration should always occur to the
288 NextPool defined in the pool definition. If no nextpool is defined, the
289 job should end with a reason of "no place to go". If Next Pool statement
290 is present, we override the check in the pool definition and use the
293 Here's how I'd define Migration Selection Types:
296 Client -- Migrate data from selected client only. Migration Selection
297 Pattern regexp provides pattern to select client names, eg ^FS00* makes
298 all client names starting with FS00 eligible for migration.
300 Jobname -- Migration all jobs matching name. Migration Selection Pattern
301 regexp provides pattern to select jobnames existing in pool.
303 Volume -- Migrate all data on specified volumes. Migration Selection
304 Pattern regexp provides selection criteria for volumes to be migrated.
305 Volumes must exist in pool to be eligible for migration.
309 LowestUtil -- Identify the volume in the pool with the least data on it
310 and empty it. No Migration Selection Pattern required.
312 OldestVol -- Identify the LRU volume with data written, and empty it. No
313 Migration Selection Pattern required.
315 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
316 (starting with most full volumes) until pool occupancy drops below
317 <lowmig>. Pool highmig and lowmig values are in pool definition, no
318 Migration Selection Pattern required.
322 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
323 Migration Selection Pattern contains SQL query to execute; should return
324 a list of 1 or more jobuids to migrate.
326 PoolResidence -- Migrate data sitting in pool for longer than
327 PoolResidence value in pool definition. Migration Selection Pattern
328 optional; if specified, override value in pool definition (value in

445 - Add VolumeLock to prevent all but lock holder (SD) from updating
446 the Volume data (with the exception of VolumeState).
447 - The btape fill command does not seem to use the Autochanger
448 - Make Windows installer default to system disk drive.
449 - Look at using ioctl(FIOBMAP, ...) on Linux, and

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

603 - Bug: if a job is manually scheduled to run later, it does not appear
604 in any status report and cannot be cancelled.
606 ==== Keeping track of deleted/new files ====
607 - To mark files as deleted, run essentially a Verify to disk, and
608 when a file is found missing (MarkId != JobId), then create
609 a new File record with FileIndex == -1. This could be done
610 by the FD at the same time as the backup.
612 My "trick" for keeping track of deletions is the following.
613 Assuming the user turns on this option, after all the files
614 have been backed up, but before the job has terminated, the
615 FD will make a pass through all the files and send their
616 names to the DIR (*exactly* the same as what a Verify job
617 currently does). This will probably be done at the same
618 time the files are being sent to the SD avoiding a second
619 pass. The DIR will then compare that to what is stored in
620 the catalog. Any files in the catalog but not in what the
621 FD sent will receive a catalog File entry that indicates
622 that at that point in time the file was deleted. This
623 either transmitted to the FD or simultaneously computed in
624 the FD, so that the FD can put a record on the tape that
625 indicates that the file has been deleted at this point.
626 A delete file entry could potentially be one with a FileIndex
627 of 0 or perhaps -1 (need to check if FileIndex is used for
628 some other thing as many of the Bacula fields are "overloaded"
631 During a restore, any file initially picked up by some
632 backup (Full, ...) then subsequently having a File entry
633 marked "delete" will be removed from the tree, so will not
634 be restored. If a file with the same name is later OK it
635 will be inserted in the tree -- this already happens. All
636 will be consistent except for possible changes during the
639 Since I'm on the subject, some of you may be wondering what
640 the utility of the in memory tree is if you are going to
641 restore everything (at least it comes up from time to time
642 on the list). Well, it is still *very* useful because it
643 allows only the last item found for a particular filename
644 (full path) to be entered into the tree, and thus if a file
645 is backed up 10 times, only the last copy will be restored.
646 I recently (last Friday) restored a complete directory, and
647 the Full and all the Differential and Incremental backups
648 spanned 3 Volumes. The first Volume was not even mounted
649 because all the files had been updated and hence backed up
650 since the Full backup was made. In this case, the tree
651 saved me a *lot* of time.
653 Make sure this information is stored on the tape too so
654 that it can be restored directly from the tape.
656 All the code (with the exception of formally generating and
657 saving the delete file entries) already exists in the Verify
658 Catalog command. It explicitly recognizes added/deleted files since
659 the last InitCatalog. It is more or less a "simple" matter of
660 taking that code and adapting it slightly to work for backups.
662 Comments from Martin Simmons (I think they are all covered):
663 Ok, that should cover the basics. There are few issues though:
665 - Restore will depend on the catalog. I think it is better to include the
666 extra data in the backup as well, so it can be seen by bscan and bextract.
668 - I'm not sure if it will preserve multiple hard links to the same inode. Or
669 maybe adding or removing links will cause the data to be dumped again?
671 - I'm not sure if it will handle renamed directories. Possibly it will work
672 by dumping the whole tree under a renamed directory?
674 - It remains to be seen how the backup performance of the DIR's will be
675 affected when comparing the catalog for a large filesystem.
679 How about introducing a Type = MgmtPolicy job type? That job type would
680 be responsible for scanning the Bacula environment looking for specific
681 conditions, and submitting the appropriate jobs for implementing said
685 Name = "Migration-Policy"
687 Policy Selection Job Type = Migrate
688 Scope = "<keyword> <operator> <regexp>"
689 Threshold = "<keyword> <operator> <regexp>"
690 Job Template = <template-name>
693 Where <keyword> is any legal job keyword, <operator> is a comparison
694 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
695 appropriate regexp. I could see an argument for Scope and Threshold
696 being SQL queries if we want to support full flexibility. The
697 Migration-Policy job would then get scheduled as frequently as a site
698 felt necessary (suggested default: every 15 minutes).
703 Name = "Migration-Policy"
705 Policy Selection Job Type = Migration
707 Threshold = "Migration Selection Type = LowestUtil"
708 Job Template = "MigrationTemplate"
711 would select all pools for examination and generate a job based on
712 MigrationTemplate to automatically select the volume with the lowest
713 usage and migrate it's contents to the nextpool defined for that pool.
715 This policy abstraction would be really handy for adjusting the behavior
716 of Bacula according to site-selectable criteria (one thing that pops
717 into mind is Amanda's ability to automatically adjust backup levels
718 depending on various criteria).
724 - Add Pool/Storage override regression test.
725 - Add delete JobId to regression.
726 - Add a regression test for dbcheck.
727 - New test to add bscan to four-concurrent-jobs regression,
728 i.e. after the four-concurrent jobs zap the
729 database as is done in the bscan-test, then use bscan to
730 restore the database, do a restore and compare with the
732 - Add restore of specific JobId to regression (item 3
733 on the restore prompt)
734 - Add IPv6 to regression
735 - Add database test to regression. Test each function like delete,
738 - AntiVir can slow down backups on Win32 systems.
739 - Win32 systems with FAT32 can be much slower than NTFS for
740 more than 1000 files per directory.
744 - A HOLD command to stop all jobs from starting.
745 - A PAUSE command to pause all running jobs ==> release the

751 === From Carsten Menke <bootsy52@gmx.net>
753 Following is a list of what I think in the situations where I'm faced with,
754 could be a usefull enhancement to bacula, which I'm certain other users will
755 benefit from as well.
757 1. NextJob/NextJobs Directive within a Job Resource in the form of
758 NextJobs = job1,job2.
761 I currently solved the problem with running multiple jobs each after each
762 by setting the Max Wait Time for a job to 8 hours, and give
763 the jobs different Priorities. However, there scenarios where
764 1 Job is directly depending on another job, so if the former job fails,
765 the job after it needn't to be run
766 while maybe other jobs should run despite of that
769 A Backup Job and a Verify job, if the backup job fails there is no need to run
770 the verify job, as the backup job already failed. However, one may like
771 to backup the Catalog to disk despite of that the main backup job failed.
774 I see that this is related to the Event Handlers which are on the ToDo
775 list, also it is maybe a good idea to check for the return value and
776 execute different actions based on the return value
779 3. offline capability to bconsole
782 Currently I use a script which I execute within the last Job via the
783 RunAfterJob Directive, to release and eject the tape.
784 So I have to call bconsole "release=Storage-Name" and afterwards
785 mt -f /dev/nst0 eject to get the tape out.
787 If I have multiple Storage Devices, than these may not be /dev/nst0 and
788 I have to modify the script or call it with parameters etc.
789 This would actually not be needed, as everything is already defined
790 in bacula-sd.conf and if I can invoke bconsole with the
791 storage name via $1 in the script than I'm done and information is
794 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
798 For the reason mentioned in 3. to have the ability to call a
799 script with /scripts/foobar %s and in the script use $1
800 to pass the Storage Name to bconsole
802 5. Setting Volume State within a Job Resource
805 Instead of using "Maximum Volume Jobs" in the Pool Resource,
806 I would have the possibilty to define
807 in a Job Resource that after this certain job is run, the Volume State
808 should be set to "Volume State = Used", this give more flexibility (IMHO).
810 6. Localization of Bacula Messages
813 Unfortunatley many,many people I work with don't speak english very well.
814 So if at least the Reporting messages would be localized then they
815 would understand that they have to change the tape,etc. etc.
817 I volunteer to do the german translations, and if I can convince my wife also
818 french and Morre (western african language).
820 7. OK, this is evil, probably bound to security risks and maybe not possible
821 due to the design of bacula.
823 Implementation of Backtics ( `command` ) for shell comand execution to
824 the "Label Format" Directive.
828 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
829 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
830 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
831 the localized name for the day of the week appended to the
832 format string. Then I have the tape labeled automatically with weekday
833 name in the correct language.
835 - Yes, that is surely the case. I probably should turn those into Warning
836 errors. In addition, you just made me think that it might not be bad to
837 add an option to check the file size after backing up the file and
838 report if it changes. This would be done as an option because it would
841 Kern, good idea. If you do do that, mention in the output: file
842 shrunk, or file expanded, just to make it obvious to the user
843 (without having to the refer to file size), just how the file size
846 Would this option be for all file, or just one file? Or a fileset?
847 - Make output from status use html table tags for nicely
848 presenting in a browser.
849 - Can one write tapes faster with 8192 byte block sizes?
850 - Document security problems with the same password for everyone in
851 rpm and Win32 releases.
852 - Browse generations of files.
853 - I've seen an error when my catalog's File table fills up. I
854 then have to recreate the File table with a larger maximum row
855 size. Relevant information is at
856 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
857 "Installing and Configuring MySQL" chapter should talk a bit
858 about this potential problem, and recommend a solution.
859 - For Solaris must use POSIX awk.
860 - Want speed of writing to tape while despooling.
861 - Supported autochanger:
869 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
870 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
871 - Add regex from http://www.pcre.org to Bacula for Win32.
872 - Use only shell tools no make in CDROM package.
873 - Include within include does it work?
874 - Implement a Pool of type Cleaning?
875 - Implement VolReadTime and VolWriteTime in SD
876 - Modify Backing up Your Database to include a bootstrap file.
877 - Think about making certain database errors fatal.
878 - Look at correcting the time jump in the scheduler for daylight
879 savings time changes.
880 - Add a "real" timer to network connections.
881 - Promote to Full = Time period
882 - Check dates entered by user for correctness (month/day/... ranges)
883 - Compress restore Volume listing by date and first file.
884 - Look at patches/bacula_db.b2z postgresql that loops during restore.
886 - Perhaps add read/write programs and/or plugins to FileSets.
887 - How to handle backing up portables ...
888 - Add some sort of guaranteed Interval for upgrading jobs.
889 - Can we write the state file after every job terminates? On Win32
890 the system crashes and the state file is not updated.
893 Documentation to do: (any release a little bit at a time)
894 - Doc to do unmount before removing magazine.
895 - Alternative to static linking "ldd prog" save all binaries listed,
896 restore them and point LD_LIBRARY_PATH to them.
897 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
898 - Document query file format.
899 - Add more documentation for bsr files.
900 - Document problems with Verify and pruning.
901 - Document how to use multiple databases.
902 - VXA drives have a "cleaning required"
903 indicator, but Exabyte recommends preventive cleaning after every 75
906 In this context, it should be noted that Exabyte has a command-line
907 vxatool utility available for free download. (The current version is
908 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
909 test the drive, unload tapes, change drive settings, flash new firmware,
911 Of particular interest in this context is that vxatool <device> -i will
912 report, among other details, the time since last cleaning in tape motion
913 minutes. This information can be retrieved (and settings changed, for
914 that matter) through the generic-SCSI device even when Bacula has the
915 regular tape device locked. (Needless to say, I don't recommend
916 changing tape settings while a job is running.)
917 - Lookup HP cleaning recommendations.
918 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
919 - Document doing table repair
922 ===================================
923 - Add macro expansions in JobDefs.
924 Run Before Job = "SomeFile %{Level} %{Client}"
925 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
926 - Use non-blocking network I/O but if no data is available, use
928 - Use gather write() for network I/O.
929 - Autorestart on crash.
930 - Add bandwidth limiting.
931 - Add acks every once and a while from the SD to keep
932 the line from timing out.
933 - When an error in input occurs and conio beeps, you can back
934 up through the prompt.
935 - Detect fixed tape block mode during positioning by looking at
936 block numbers in btape "test". Possibly adjust in Bacula.
937 - Fix list volumes to output volume retention in some other
938 units, perhaps via a directive.
939 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
940 with multiple priorities.
941 - If you use restore replace=never, the directory attributes for
942 non-existent directories will not be restored properly.
944 - see lzma401.zip in others directory for new compression
946 - Allow the user to select JobType for manual pruning/purging.
947 - bscan does not put first of two volumes back with all info in
949 - Implement the FreeBSD nodump flag in chflags.
950 - Figure out how to make named console messages go only to that
951 console and to the non-restricted console (new console class?).
952 - Make restricted console prompt for password if *ask* is set or
953 perhaps if password is undefined.
954 - Implement "from ISO-date/time every x hours/days/weeks/months" in
957 ==== from Marc Schoechlin
958 - the help-command should be more verbose
959 (it should explain the paramters of the different
961 -> its time-comsuming to consult the manual anytime
962 you need a special parameter
963 -> maybe its more easy to maintain this, if the
964 descriptions of that commands are outsourced to
966 - the cd-command should allow complete paths
967 i.e. cd /foo/bar/foo/bar
968 -> if a customer mails me the path to a certain file,
969 its faster to enter the specified directory
970 - if the password is not configured in bconsole.conf
971 you should be asked for it.
972 -> sometimes you like to do restore on a customer-machine
973 which shouldnt know the password for bacula.
974 -> adding the password to the file favours admins
975 to forget to remove the password after usage
977 the protection of that file is less important
978 - long-listed-output of commands should be scrollable
979 like the unix more/less-command does
980 -> if someone runs 200 and more machines, the lists could
981 be a little long and complex
982 - command-output should be shown column by column
983 to reduce scrolling and to increase clarity
985 - lsmark should list the selected files with full
987 - wildcards for selecting and file and directories would be nice
988 - any actions should be interuptable with STRG+C
989 - command-expansion would be pretty cool
991 - When the replace Never option is set, new directory permissions
992 are not restored. See bug 213. To fix this requires creating a
993 list of newly restored directories so that those directory
994 permissions *can* be restored.
995 - Add prune all command
996 - Document fact that purge can destroy a part of a restore by purging
997 one volume while others remain valid -- perhaps mark Jobs.
998 - Add multiple-media-types.txt
999 - look at mxt-changer.html
1000 - Make ? do a help command (no return needed).
1001 - Implement restore directory.
1002 - Document streams and how to implement them.
1003 - Try not to re-backup a file if a new hard link is added.
1004 - Add feature to backup hard links only, but not the data.
1005 - Fix stream handling to be simpler.
1006 - Add Priority and Bootstrap to Run a Job.
1007 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1009 - Remove View FileSet button from Run a Job dialog.
1010 - Handle prompt for restore job at end of Restore command.
1011 - Add display of total selected files to Restore window.
1012 - Add tree pane to left of window.
1013 - Add progress meter.
1014 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1015 - Add message to user to check for fixed block size when the forward
1016 space test fails in btape.
1017 - When unmarking a directory check if all files below are unmarked and
1018 then remove the + flag -- in the restore tree.
1019 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1020 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1021 - Revisit the question of multiple Volumes (disk) on a single device.
1022 - Add a block copy option to bcopy.
1023 - Finish work on Gnome restore GUI.
1024 - Fix "llist jobid=xx" where no fileset or client exists.
1025 - For each job type (Admin, Restore, ...) require only the really necessary
1026 fields.- Pass Director resource name as an option to the Console.
1027 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1028 - Add a .list all files in the restore tree (probably also a list all files)
1029 Do both a long and short form.
1030 - Allow browsing the catalog to see all versions of a file (with
1031 stat data on each file).
1032 - Restore attributes of directory if replace=never set but directory
1034 - Use SHA1 on authentication if possible.
1035 - See comtest-xxx.zip for Windows code to talk to USB.
1036 - Add John's appended files:
1037 Appended = { /files/server/logs/http/*log }
1038 and such files would be treated as follows.On a FULL backup, they would
1039 be backed up like any other file.On an INCREMENTAL backup, where a
1040 previous INCREMENTAL or FULL was already in thecatalogue and the length
1041 of the file wasgreater than the length of the last backup, only thedata
1042 added since the last backup will be dumped.On an INCREMENTAL backup, if
1043 the length of the file is less than thelength of the file with the same
1044 name last backed up, the completefile is dumped.On Windows systems, with
1045 creation date of files, we can be evensmarter about this and not count
1046 entirely upon the length.On a restore, the full and all incrementals
1047 since it will beapplied in sequence to restore the file.
1048 - Check new HAVE_WIN32 open bits.
1049 - Check if the tape has moved before writing.
1050 - Handling removable disks -- see below:
1051 - Keep track of tape use time, and report when cleaning is necessary.
1052 - Add FromClient and ToClient keywords on restore command (or
1053 BackupClient RestoreClient).
1054 - Implement a JobSet, which groups any number of jobs. If the
1055 JobSet is started, all the jobs are started together.
1056 Allow Pool, Level, and Schedule overrides.
1057 - Enhance cancel to timeout BSOCK packets after a specific delay.
1058 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1059 ua_status.!!! Thanks to Alan Brown for this tip.
1060 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1061 correctly for multiple simultaneous jobs.
1062 - Correct code so that FileSet MD5 is calculated for < and | filename
1064 - Implement the Media record flag that indicates that the Volume does disk
1066 - Implement VolAddr, which is used when Volume is addressed like a disk,
1067 and form it from VolFile and VolBlock.
1068 - Make multiple restore jobs for multiple media types specifying
1069 the proper storage type.
1070 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1071 pointer (rec) to try_repositioning().
1072 - Look at extracting Win data from BackupRead.
1073 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1074 which would take precidence over the Catalog "JobRetention".
1075 - Implement Label Format in Add and Label console commands.
1076 - Possibly up network buffers to 65K. Put on variable.
1077 - Put email tape request delays on one or more variables. User wants
1078 to cancel the job after a certain time interval. Maximum Mount Wait?
1079 - Job, Client, Device, Pool, or Volume?
1080 Is it possible to make this a directive which is *optional* in multiple
1081 resources, like Level? If so, I think I'd make it an optional directive
1082 in Job, Client, and Pool, with precedence such that Job overrides Client
1083 which in turn overrides Pool.
1085 - New Storage specifications:
1086 - Want to write to multiple storage devices simultaneously
1087 - Want to write to multiple storage devices sequentially (in one job)
1088 - Want to read/write simultaneously
1089 - Key is MediaType -- it must match
1091 Passed to SD as a sort of BSR record called Storage Specification
1095 MediaType -> Next MediaType
1097 Device -> Next Device
1099 Allow multiple Storage specifications
1107 Allow Multiple Pool specifications (note, Pool currently
1109 Allow Multiple MediaType specifications in Dir conf
1110 Allow Multiple Device specifications in Dir conf
1111 Perhaps keep this in a single SSR
1112 Tie a Volume to a specific device by using a MediaType that
1113 is contained in only one device.
1114 In SD allow Device to have Multiple MediaTypes
1116 - Ideas from Jerry Scharf:
1117 First let's point out some big pluses that bacula has for this
1119 more importantly it's active. Thank you so much for that
1120 even more important, it's not flaky
1121 it has an open access catalog, opening many possibilities
1122 it's pushing toward heterogeneous systems capability
1124 Macintosh file client
1125 macs are an interesting niche, but I fear a server is a rathole
1126 working bare iron recovery for windows
1127 the option for inc/diff backups not reset on fileset revision

1129 b) do the full catalog check (expensive but accurate)

1132 an integration guide
1133 or how to get at fancy things that one could do with bacula
1134 logwatch code for bacula logs (or similar)
1135 linux distro inclusion of bacula (brings good and bad, but necessary)
1136 win2k/XP server capability (icky but you asked)
1137 support for Oracle database ??
1139 - Look at adding SQL server and Exchange support for Windows.
1140 - Make dev->file and dev->block_num signed integers so that -1 can
1141 be an invalid value which happens with BSR.
1142 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1143 is needed to properly specify ranges.
1144 - Add progress of files/bytes to SD and FD.
1145 - Print warning message if FileId > 4 billion
1146 - do a "messages" before the first prompt in Console
1147 - Client does not show busy during Estimate command.
1148 - Implement Console mtx commands.
1149 - Implement a Mount Command and an Unmount Command where
1150 the users could specify a system command to be performed
1151 to do the mount, after which Bacula could attempt to
1152 read the device. This is for Removeable media such as a CDROM.
1153 - Most likely, this mount command would be invoked explicitly
1154 by the user using the current Console "mount" and "unmount"
1155 commands -- the Storage Daemon would do the right thing
1156 depending on the exact nature of the device.
1157 - As with tape drives, when Bacula wanted a new removable
1158 disk mounted, it would unmount the old one, and send a message
1159 to the user, who would then use "mount" as described above
1160 once he had actually inserted the disk.
1161 - Implement dump/print label to UA
1162 - Spool to disk only when the tape is full, then when a tape is hung move
1164 - bextract is sending everything to the log file ****FIXME****
1165 - Allow multiple Storage specifications (or multiple names on
1166 a single Storage specification) in the Job record. Thus a job
1167 can be backed up to a number of storage devices.
1168 - Implement some way for the File daemon to contact the Director
1169 to start a job or pass its DHCP obtained IP number.
1170 - Implement a query tape prompt/replace feature for a console
1171 - Copy console @ code to gnome2-console
1172 - Make tree walk routines like cd, ls, ... more user friendly
1173 by handling spaces better.
1174 - Make sure that Bacula rechecks the tape after the 20 min wait.
1175 - Set IO_NOWAIT on Bacula TCP/IP packets.
1176 - Try doing a raw partition backup and restore by mounting a
1178 - From Lars Kellers:
1179 Yes, it would allow to highly automatic the request for new tapes. If a
1180 tape is empty, bacula reads the barcodes (native or simulated), and if
1181 an unused tape is found, it runs the label command with all the
1182 necessary parameters.
1184 By the way can bacula automatically "move" an empty/purged volume say
1185 in the "short" pool to the "long" pool if this pool runs out of volume
1187 - What to do about "list files job=xxx".
1188 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1189 file descriptor leak in Bacula.
1190 - Implement WrapCounters in Counters.
1191 - Add heartbeat from FD to SD if hb interval expires.
1192 - Can we dynamically change FileSets?
1193 - If pool specified to label command and Label Format is specified,
1194 automatically generate the Volume name.
1195 - Why can't SQL do the filename sort for restore?
1196 - Add ExhautiveRestoreSearch
1197 - Look at the possibility of loading only the necessary
1198 data into the restore tree (i.e. do it one directory at a
1199 time as the user walks through the tree).
1200 - Possibly use the hash code if the user selects all for a restore command.
1201 - Fix "restore all" to bypass building the tree.
1202 - Prohibit backing up archive device (findlib/find_one.c:128)
1203 - Implement Release Device in the Job resource to unmount a drive.
1204 - Implement Acquire Device in the Job resource to mount a drive,
1205 be sure this works with admin jobs so that the user can get
1206 prompted to insert the correct tape. Possibly some way to say to
1207 run the job but don't save the files.
1208 - Make things like list where a file is saved case independent for
1210 - Use autochanger to handle multiple devices.
1211 - Implement a Recycle command
1212 - Start working on Base jobs.
1213 - Implement UnsavedFiles DB record.
1214 - From Phil Stracchino:
1215 It would probably be a per-client option, and would be called
1216 something like, say, "Automatically purge obsoleted jobs". What it
1217 would do is, when you successfully complete a Differential backup of a
1218 client, it would automatically purge all Incremental backups for that
1219 client that are rendered redundant by that Differential. Likewise,
1220 when a Full backup on a client completed, it would automatically purge
1221 all Differential and Incremental jobs obsoleted by that Full backup.
1222 This would let people minimize the number of tapes they're keeping on
1223 hand without having to master the art of retention times.
1224 - When doing a Backup send all attributes back to the Director, who
1225 would then figure out what files have been deleted.
1226 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1227 explicit permission to do so. It should also mark the tape in error
1228 if there is an error.
1229 - Cancel waiting for Client connect in SD if FD goes away.
1231 - Implement timeout in response() when it should come quickly.
1232 - Implement a Slot priority (loaded/not loaded).
1233 - Implement "vacation" Incremental only saves.
1234 - Implement create "FileSet"?
1235 - Add prefixlinks to where or not where absolute links to FD.
1236 - Issue message to mount a new tape before the rewind.
1237 - Simplified client job initiation for portables.
1238 - If SD cannot open a drive, make it periodically retry.
1239 - Add more of the config info to the tape label.
1241 - Refine SD waiting output:
1242 Device is being positioned
1243 > Device is being positioned for append
1244 > Device is being positioned to file x
1246 - Figure out some way to estimate output size and to avoid splitting
1247 a backup across two Volumes -- this could be useful for writing CDROMs
1248 where you really prefer not to have it split -- not serious.
1249 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1250 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1251 actual data on the Volume and compare it.
1252 - Implement Bacula plugins -- design API
1253 - Make bcopy read through bad tape records.
1254 - Program files (i.e. execute a program to read/write files).
1255 Pass read date of last backup, size of file last time.
1256 - Add Signature type to File DB record.
1257 - CD into subdirectory when open()ing files for backup to
1258 speed up things. Test with testfind().
1259 - Priority job to go to top of list.
1260 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1261 - Implement some way for the Console to dynamically create a job.
1262 - Solaris -I on tar for include list
1263 - Need a verbose mode in restore, perhaps to bsr.
1264 - bscan without -v is too quiet -- perhaps show jobs.
1265 - Add code to reject whole blocks if not wanted on restore.
1266 - Check if we can increase Bacula FD priorty in Win2000
1267 - Make sure the MaxVolFiles is fully implemented in SD
1268 - Check if both CatalogFiles and UseCatalog are set to SD.
1269 - Possibly add email to Watchdog if drive is unmounted too
1270 long and a job is waiting on the drive.
1271 - After unmount, if restore job started, ask to mount.
1272 - Add UA rc and history files.
1273 - put termcap (used by console) in ./configure and
1274 allow -with-termcap-dir.
1275 - Fix Autoprune for Volumes to respect need for full save.
1276 - Compare tape to Client files (attributes, or attributes and data)
1277 - Make all database Ids 64 bit.
1278 - Allow console commands to detach or run in background.
1279 - Add SD message variables to control operator wait time
1280 - Maximum Operator Wait
1281 - Minimum Message Interval
1282 - Maximum Message Interval
1283 - Send Operator message when cannot read tape label.
1284 - Verify level=Volume (scan only), level=Data (compare of data to file).
1285 Verify level=Catalog, level=InitCatalog
1287 - Add keyword search to show command in Console.
1288 - Events : tape has more than xxx bytes.
1289 - Complete code in Bacula Resources -- this will permit
1290 reading a new config file at any time.
1291 - Handle ctl-c in Console
1292 - Implement script driven addition of File daemon to config files.
1293 - Think about how to make Bacula work better with File (non-tape) archives.
1294 - Write Unix emulator for Windows.
1295 - Put memory utilization in Status output of each daemon
1296 if full status requested or if some level of debug on.
1297 - Make database type selectable by .conf files i.e. at runtime
1298 - Set flag for uname -a. Add to Volume label.
1299 - Restore files modified after date
1300 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1301 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1302 - Timout a job or terminate if link goes down, or reopen link and query.
1303 - Concept of precious tapes (cannot be reused).
1304 - Make bcopy copy with a single tape drive.
1305 - Permit changing ownership during restore.

1319 - Autolabel should be specified by DIR instead of SD.
1321 - Add media capacity
1322 - AutoScan (check checksum of tape)
1323 - Format command = "format /dev/nst0"
1327 - Seek resolution (usually corresponds to buffer size)
1328 - EODErrorCode=ENOSPC or code
1329 - Partial Read error code
1330 - Partial write error code
1331 - Nonformatted read error

1347 - FD sends unsaved file list to Director at end of job (see
1349 - File daemon should build list of files skipped, and then
1350 at end of save retry and report any errors.
1351 - Write a Storage daemon that uses pipes and
1352 standard Unix programs to write to the tape.
1354 - Need something that monitors the JCR queue and
1355 times out jobs by asking the deamons where they are.
1356 - Enhance Jmsg code to permit buffering and saving to disk.
1357 - device driver = "xxxx" for drives.
1358 - Verify from Volume
1359 - Ensure that /dev/null works
1360 - Need report class for messages. Perhaps
1361 report resource where report=group of messages
1362 - enhance scan_attrib and rename scan_jobtype, and
1363 fill in code for "since" option
1364 - Director needs a time after which the report status is sent
1365 anyway -- or better yet, a retry time for the job.
1366 - Don't reschedule a job if previous incarnation is still running.
1367 - Some way to automatically backup everything is needed????
1368 - Need a structure for pending actions:
1370 - termination status (part of buffered msgs?)
1372 Read, Write, Clean, Delete
1373 - Login to Bacula; Bacula users with different permissions:
1374 owner, group, user, quotas
1375 - Store info on each file system type (probably in the job header on tape.
1376 This could be the output of df; or perhaps some sort of /etc/mtab record.
1378 ========= ideas ===============
1379 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1380 To: <kern@sibbald.com>
1381 Subject: RE: [Bacula-users] future large programming jobs
1382 Date: Thu, 26 Feb 2004 11:34:54 -0600
1384 I noticed the subject thread and thought I would offer the following
1385 merely as sources of ideas, i.e. something to think about, not even as
1386 strong as a request. In my former life (before retiring) I often
1387 dealt with backups and storage management issues/products as a
1388 developer and as a consultant. I am currently migrating my personal
1389 network from amanda to bacula specifically because of the ability to
1390 cross media boundaries during storing backups.
1391 Are you familiar with the commercial product called ADSM (I think IBM
1392 now sells it under the Tivoli label)? It has a couple of interesting
1393 ideas that may apply to the following topics.
1395 1. Migration: Consider that when you need to restore a system, there
1396 may be pressure to hurry. If all the information for a single client
1397 can eventually end up on the same media (and in chronological order),
1398 the restore is facillitated by not having to search past information
1399 from other clients. ADSM has the concept of "client affinity" that
1400 may be associated with it's storage pools. It seems to me that this
1401 concept (as an optional feature) might fit in your architecture for
1404 ADSM also has the concept of defining one or more storage pools as
1405 "copy pools" (almost mirrors, but only in the sense of contents).
1406 These pools provide the ability to have duplicte data stored both
1407 onsite and offsite. The copy process can be scheduled to be handled
1408 by their storage manager during periods when there is no backup
1409 activity. Again, the migration process might be a place to consider
1410 implementing something like this.
1413 > It strikes me that it would be very nice to be able to do things
1415 > have the Job(s) backing up the machines run, and once they have all

1421 > mechanism described below would probably make it very easy.
1423 This is the goal. In the first step (before events), you simply
1425 the Migration to tape later.
1427 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1428 the database. Once a file (unique by path and metadata such as dates,
1429 size, ownership, etc.) is in a copy pool, no more copies are made. In
1430 other words, when you start ADSM, it begins like your concept of a
1431 base job. After that it is in the "incremental" mode. You can
1432 configure the number of "generations" of files to be retained, plus a
1433 retention date after which even old generations are purged. The
1434 database tracks the contents of media and projects the percentage of
1435 each volume that is valid. When the valid content of a volume drops
1436 below a configured percentage, the valid data are migrated to another
1437 volume and the old volume is marked as empty. Note, this requires
1438 ADSM to have an idea of the contents of a client, i.e. marking the
1439 database when an existing file was deleted, but this would solve your
1440 issue of restoring a client without restoring deleted files.
1442 This is pretty far from what bacula now does, but if you are going to
1443 rip things up for Base jobs,.....
1444 Also, the benefits of this are huge for very large shops, especially
1445 with media robots, but are a pain for shops with manual media
1449 > Base jobs sound pretty useful, but I'm not dying for them.
1451 Nobody is dying for them, but when you see what it does, you will die
1454 3. Restoring deleted files: Since I think my comments in (2) above
1455 have low probability of implementation, I'll also suggest that you
1456 could approach the issue of deleted files by a mechanism of having the
1457 fd report to the dir, a list of all files on the client for every
1458 backup job. The dir could note in the database entry for each file
1459 the date that the file was seen. Then if a restore as of date X takes
1460 place, only files that exist from before X until after X would be
1461 restored. Probably the major cost here is the extra date container in
1462 each row of the files table.
1464 Thanks for "listening". I hope some of this helps. If you want to
1465 contact me, please send me an email - I read some but not all of the
1466 mailing list traffic and might miss a reply there.
1468 Please accept my compliments for bacula. It is doing a great job for
1469 me!! I sympathize with you in the need to wrestle with excelence in
1470 execution vs. excelence in feature inclusion.
1475 ==============================
1478 - Design at hierarchial storage for Bacula. Migration and Clone.
1479 - Implement FSM (File System Modules).
1480 - Audit M_ error codes to ensure they are correct and consistent.
1481 - Add variable break characters to lex analyzer.
1482 Either a bit mask or a string of chars so that
1483 the caller can change the break characters.
1484 - Make a single T_BREAK to replace T_COMMA, etc.
1485 - Ensure that File daemon and Storage daemon can
1486 continue a save if the Director goes down (this
1487 is NOT currently the case). Must detect socket error,
1488 buffer messages for later.
1489 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1490 - Add ability to backup to two Storage devices (two SD sessions) at
1491 the same time -- e.g. onsite, offsite.
1492 - Add the ability to consolidate old backup sets (basically do a restore
1493 to tape and appropriately update the catalog). Compress Volume sets.
1494 Might need to spool via file is only one drive is available.
1495 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1496 someway to do so with every volume that has less than x% valid
1500 Migration: Move a backup from one Volume to another
1501 Clone: Copy a backup -- two Volumes
1504 ======================================================
1506 It is somewhat like a Full save becomes an incremental since
1507 the Base job (or jobs) plus other non-base files.
1509 - A Base backup is same as Full backup, just different type.
1510 - New BaseFiles table that contains:
1512 BaseJobId - Base JobId referenced for this FileId (needed ???)
1513 JobId - JobId currently running
1514 FileId - File not backed up, exists in Base Job
1515 FileIndex - FileIndex from Base Job.
1516 i.e. for each base file that exists but is not saved because
1517 it has not changed, the File daemon sends the JobId, BaseId,
1518 FileId, FileIndex back to the Director who creates the DB entry.
1519 - To initiate a Base save, the Director sends the FD
1520 the FileId, and full filename for each file in the Base.
1521 - When the FD finds a Base file, he requests the Director to
1522 send him the full File entry (stat packet plus MD5), or
1523 conversely, the FD sends it to the Director and the Director
1524 says yes or no. This can be quite rapid if the FileId is kept
1525 by the FD for each Base Filename.
1526 - It is probably better to have the comparison done by the FD
1527 despite the fact that the File entry must be sent across the
1529 - An alternative would be to send the FD the whole File entry
1530 from the start. The disadvantage is that it requires a lot of
1531 space. The advantage is that it requires less communications
1533 - The Job record must be updated to indicate that one or more
1535 - At end of Job, FD returns:
1536 1. Count of base files/bytes not written to tape (i.e. matches)
1537 2. Count of base file that were saved i.e. had changed.
1538 - No tape record would be written for a Base file that matches, in the
1539 same way that no tape record is written for Incremental jobs where
1540 the file is not saved because it is unchanged.
1541 - On a restore, all the Base file records must explicitly be
1542 found from the BaseFile tape. I.e. for each Full save that is marked
1543 to have one or more Base Jobs, search the BaseFile for all occurrences
1545 - An optimization might be to make the BaseFile have:
1551 This would avoid the need to explicitly fetch each File record for
1552 the Base job. The Base Job record will be fetched to get the
1553 VolSessionId and VolSessionTime.
1554 =========================================================
1557 ==========================================================
1559 For each Incremental job that is run, there may be files that
1560 were found but not saved because they were locked (this applies
1561 only to Windows). Such a system could send back to the Director
1562 a list of Unsaved files.
1564 - New UnSavedFiles table that contains:
1568 - Then in the next Incremental job, the list of Unsaved Files will be
1569 feed to the FD, who will ensure that they are explicitly chosen even
1570 if standard date/time check would not have selected them.

1615 There needs to be a table of drive # to devices somewhere - If there are
1616 multiple changers or drives there may not be a 1:1 correspondance between
1617 changer drive number and system device name - and depending on the way the
1618 drives are hooked up to scsi busses, they may not be linearly numbered
1619 from an offset point either.something like
1621 Autochanger drives = 2
1622 Autochanger drive 0 = /dev/nst1
1623 Autochanger drive 1 = /dev/nst2
1624 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1625 times, not just for multidrive changers. For a 1 drive changer, that's
1631 MTX's manpage (1.2.15):
1632 unload [<slotnum>] [ <drivenum> ]
1633 Unloads media from drive <drivenum> into slot
1634 <slotnum>. If <drivenum> is omitted, defaults to
1635 drive 0 (as do all commands). If <slotnum> is
1636 omitted, defaults to the slot that the drive was
1637 loaded from. Note that there's currently no way
1638 to say 'unload drive 1's media to the slot it
1639 came from', other than to explicitly use that
1640 slot number as the destination.AB

1678 Handling removable disks
1680 From: Karl Cunningham <karlc@keckec.com>
1682 My backups are only to hard disk these days, in removable bays. This is my
1683 idea of how a backup to hard disk would work more smoothly. Some of these
1684 things Bacula does already, but I mention them for completeness. If others
1685 have better ways to do this, I'd like to hear about it.
1687 1. Accommodate several disks, rotated similar to how tapes are. Identified
1688 by partition volume ID or perhaps by the name of a subdirectory.
1689 2. Abort & notify the admin if the wrong disk is in the bay.
1690 3. Write backups to different subdirectories for each machine to be backed
1692 4. Volumes (files) get created as needed in the proper subdirectory, one
1694 5. When a disk is recycled, remove or zero all old backup files. This is
1695 important as the disk being recycled may be close to full. This may be
1696 better done manually since the backup files for many machines may be
1697 scattered in many subdirectories.
1702 - Why the heck doesn't bacula drop root priviledges before connecting to
1704 - Look at using posix_fadvise(2) for backups -- see bug #751.
1705 Possibly add the code at findlib/bfile.c:795
1706 /* TCP socket options */
1707 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1708 - Fix bnet_connect() code to set a timer and to use time to
1710 - Implement 4th argument to make_catalog_backup that passes hostname.
1711 - Test FIFO backup/restore -- make regression
1712 - Please mount volume "xxx" on Storage device ... should also list
1713 Pool and MediaType in case user needs to create a new volume.
