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

61 specified Pool, Full Backup Pool. and Differential Backup Pool. but
62 apparently not. This happened when I removed the pool directive and

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

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

441 the Volume data (with the exception of VolumeState).
442 - The btape fill command does not seem to use the Autochanger
443 - Make Windows installer default to system disk drive.

464 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
465 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
466 - Implement a mode that says when a hard read error is
467 encountered, read many times (as it currently does), and if the
468 block cannot be read, skip to the next block, and try again. If
469 that fails, skip to the next file and try again, ...

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

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

746 === From Carsten Menke <bootsy52@gmx.net>
748 Following is a list of what I think in the situations where I'm faced with,
749 could be a usefull enhancement to bacula, which I'm certain other users will
750 benefit from as well.
752 1. NextJob/NextJobs Directive within a Job Resource in the form of
753 NextJobs = job1,job2.
756 I currently solved the problem with running multiple jobs each after each
757 by setting the Max Wait Time for a job to 8 hours, and give
758 the jobs different Priorities. However, there scenarios where
759 1 Job is directly depending on another job, so if the former job fails,
760 the job after it needn't to be run
761 while maybe other jobs should run despite of that
764 A Backup Job and a Verify job, if the backup job fails there is no need to run
765 the verify job, as the backup job already failed. However, one may like
766 to backup the Catalog to disk despite of that the main backup job failed.
769 I see that this is related to the Event Handlers which are on the ToDo
770 list, also it is maybe a good idea to check for the return value and
771 execute different actions based on the return value
774 3. offline capability to bconsole
777 Currently I use a script which I execute within the last Job via the
778 RunAfterJob Directive, to release and eject the tape.
779 So I have to call bconsole "release=Storage-Name" and afterwards
780 mt -f /dev/nst0 eject to get the tape out.
782 If I have multiple Storage Devices, than these may not be /dev/nst0 and
783 I have to modify the script or call it with parameters etc.
784 This would actually not be needed, as everything is already defined
785 in bacula-sd.conf and if I can invoke bconsole with the
786 storage name via $1 in the script than I'm done and information is
789 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
793 For the reason mentioned in 3. to have the ability to call a
794 script with /scripts/foobar %s and in the script use $1
795 to pass the Storage Name to bconsole
797 5. Setting Volume State within a Job Resource
800 Instead of using "Maximum Volume Jobs" in the Pool Resource,
801 I would have the possibilty to define
802 in a Job Resource that after this certain job is run, the Volume State
803 should be set to "Volume State = Used", this give more flexibility (IMHO).
805 6. Localization of Bacula Messages
808 Unfortunatley many,many people I work with don't speak english very well.
809 So if at least the Reporting messages would be localized then they
810 would understand that they have to change the tape,etc. etc.
812 I volunteer to do the german translations, and if I can convince my wife also
813 french and Morre (western african language).
815 7. OK, this is evil, probably bound to security risks and maybe not possible
816 due to the design of bacula.
818 Implementation of Backtics ( `command` ) for shell comand execution to
819 the "Label Format" Directive.
823 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
824 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
825 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
826 the localized name for the day of the week appended to the
827 format string. Then I have the tape labeled automatically with weekday
828 name in the correct language.
830 - Yes, that is surely the case. I probably should turn those into Warning
831 errors. In addition, you just made me think that it might not be bad to
832 add an option to check the file size after backing up the file and
833 report if it changes. This would be done as an option because it would
836 Kern, good idea. If you do do that, mention in the output: file
837 shrunk, or file expanded, just to make it obvious to the user
838 (without having to the refer to file size), just how the file size
841 Would this option be for all file, or just one file? Or a fileset?
842 - Make output from status use html table tags for nicely
843 presenting in a browser.
844 - Can one write tapes faster with 8192 byte block sizes?
845 - Document security problems with the same password for everyone in
846 rpm and Win32 releases.
847 - Browse generations of files.
848 - I've seen an error when my catalog's File table fills up. I
849 then have to recreate the File table with a larger maximum row
850 size. Relevant information is at
851 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
852 "Installing and Configuring MySQL" chapter should talk a bit
853 about this potential problem, and recommend a solution.
854 - For Solaris must use POSIX awk.
855 - Want speed of writing to tape while despooling.
856 - Supported autochanger:
864 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
865 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
866 - Add regex from http://www.pcre.org to Bacula for Win32.
867 - Use only shell tools no make in CDROM package.
868 - Include within include does it work?
869 - Implement a Pool of type Cleaning?
870 - Implement VolReadTime and VolWriteTime in SD
871 - Modify Backing up Your Database to include a bootstrap file.
872 - Think about making certain database errors fatal.
873 - Look at correcting the time jump in the scheduler for daylight
874 savings time changes.
875 - Add a "real" timer to network connections.
876 - Promote to Full = Time period
877 - Check dates entered by user for correctness (month/day/... ranges)
878 - Compress restore Volume listing by date and first file.
879 - Look at patches/bacula_db.b2z postgresql that loops during restore.
881 - Perhaps add read/write programs and/or plugins to FileSets.
882 - How to handle backing up portables ...
883 - Add some sort of guaranteed Interval for upgrading jobs.
884 - Can we write the state file after every job terminates? On Win32
885 the system crashes and the state file is not updated.
888 Documentation to do: (any release a little bit at a time)
889 - Doc to do unmount before removing magazine.
890 - Alternative to static linking "ldd prog" save all binaries listed,
891 restore them and point LD_LIBRARY_PATH to them.
892 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
893 - Document query file format.
894 - Add more documentation for bsr files.
895 - Document problems with Verify and pruning.
896 - Document how to use multiple databases.
897 - VXA drives have a "cleaning required"
898 indicator, but Exabyte recommends preventive cleaning after every 75
901 In this context, it should be noted that Exabyte has a command-line
902 vxatool utility available for free download. (The current version is
903 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
904 test the drive, unload tapes, change drive settings, flash new firmware,
906 Of particular interest in this context is that vxatool <device> -i will
907 report, among other details, the time since last cleaning in tape motion
908 minutes. This information can be retrieved (and settings changed, for
909 that matter) through the generic-SCSI device even when Bacula has the
910 regular tape device locked. (Needless to say, I don't recommend
911 changing tape settings while a job is running.)
912 - Lookup HP cleaning recommendations.
913 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
914 - Document doing table repair
917 ===================================
918 - Add macro expansions in JobDefs.
919 Run Before Job = "SomeFile %{Level} %{Client}"
920 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
921 - Use non-blocking network I/O but if no data is available, use
923 - Use gather write() for network I/O.
924 - Autorestart on crash.
925 - Add bandwidth limiting.
926 - Add acks every once and a while from the SD to keep
927 the line from timing out.
928 - When an error in input occurs and conio beeps, you can back
929 up through the prompt.
930 - Detect fixed tape block mode during positioning by looking at
931 block numbers in btape "test". Possibly adjust in Bacula.
932 - Fix list volumes to output volume retention in some other
933 units, perhaps via a directive.
934 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
935 with multiple priorities.
936 - If you use restore replace=never, the directory attributes for
937 non-existent directories will not be restored properly.
939 - see lzma401.zip in others directory for new compression
941 - Allow the user to select JobType for manual pruning/purging.
942 - bscan does not put first of two volumes back with all info in
944 - Implement the FreeBSD nodump flag in chflags.
945 - Figure out how to make named console messages go only to that
946 console and to the non-restricted console (new console class?).
947 - Make restricted console prompt for password if *ask* is set or
948 perhaps if password is undefined.
949 - Implement "from ISO-date/time every x hours/days/weeks/months" in
952 ==== from Marc Schoechlin
953 - the help-command should be more verbose
954 (it should explain the paramters of the different
956 -> its time-comsuming to consult the manual anytime
957 you need a special parameter
958 -> maybe its more easy to maintain this, if the
959 descriptions of that commands are outsourced to
961 - the cd-command should allow complete paths
962 i.e. cd /foo/bar/foo/bar
963 -> if a customer mails me the path to a certain file,
964 its faster to enter the specified directory
965 - if the password is not configured in bconsole.conf
966 you should be asked for it.
967 -> sometimes you like to do restore on a customer-machine
968 which shouldnt know the password for bacula.
969 -> adding the password to the file favours admins
970 to forget to remove the password after usage
972 the protection of that file is less important
973 - long-listed-output of commands should be scrollable
974 like the unix more/less-command does
975 -> if someone runs 200 and more machines, the lists could
976 be a little long and complex
977 - command-output should be shown column by column
978 to reduce scrolling and to increase clarity
980 - lsmark should list the selected files with full
982 - wildcards for selecting and file and directories would be nice
983 - any actions should be interuptable with STRG+C
984 - command-expansion would be pretty cool
986 - When the replace Never option is set, new directory permissions
987 are not restored. See bug 213. To fix this requires creating a
988 list of newly restored directories so that those directory
989 permissions *can* be restored.
990 - Add prune all command
991 - Document fact that purge can destroy a part of a restore by purging
992 one volume while others remain valid -- perhaps mark Jobs.
993 - Add multiple-media-types.txt
994 - look at mxt-changer.html
995 - Make ? do a help command (no return needed).
996 - Implement restore directory.
997 - Document streams and how to implement them.
998 - Try not to re-backup a file if a new hard link is added.
999 - Add feature to backup hard links only, but not the data.
1000 - Fix stream handling to be simpler.
1001 - Add Priority and Bootstrap to Run a Job.
1002 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1004 - Remove View FileSet button from Run a Job dialog.
1005 - Handle prompt for restore job at end of Restore command.
1006 - Add display of total selected files to Restore window.
1007 - Add tree pane to left of window.
1008 - Add progress meter.
1009 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1010 - Add message to user to check for fixed block size when the forward
1011 space test fails in btape.
1012 - When unmarking a directory check if all files below are unmarked and
1013 then remove the + flag -- in the restore tree.
1014 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1015 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1016 - Revisit the question of multiple Volumes (disk) on a single device.
1017 - Add a block copy option to bcopy.
1018 - Finish work on Gnome restore GUI.
1019 - Fix "llist jobid=xx" where no fileset or client exists.
1020 - For each job type (Admin, Restore, ...) require only the really necessary
1021 fields.- Pass Director resource name as an option to the Console.
1022 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1023 - Add a .list all files in the restore tree (probably also a list all files)
1024 Do both a long and short form.
1025 - Allow browsing the catalog to see all versions of a file (with
1026 stat data on each file).
1027 - Restore attributes of directory if replace=never set but directory
1029 - Use SHA1 on authentication if possible.
1030 - See comtest-xxx.zip for Windows code to talk to USB.
1031 - Add John's appended files:
1032 Appended = { /files/server/logs/http/*log }
1033 and such files would be treated as follows.On a FULL backup, they would
1034 be backed up like any other file.On an INCREMENTAL backup, where a
1035 previous INCREMENTAL or FULL was already in thecatalogue and the length
1036 of the file wasgreater than the length of the last backup, only thedata
1037 added since the last backup will be dumped.On an INCREMENTAL backup, if
1038 the length of the file is less than thelength of the file with the same
1039 name last backed up, the completefile is dumped.On Windows systems, with
1040 creation date of files, we can be evensmarter about this and not count
1041 entirely upon the length.On a restore, the full and all incrementals
1042 since it will beapplied in sequence to restore the file.
1043 - Check new HAVE_WIN32 open bits.
1044 - Check if the tape has moved before writing.
1045 - Handling removable disks -- see below:
1046 - Keep track of tape use time, and report when cleaning is necessary.
1047 - Add FromClient and ToClient keywords on restore command (or
1048 BackupClient RestoreClient).
1049 - Implement a JobSet, which groups any number of jobs. If the
1050 JobSet is started, all the jobs are started together.
1051 Allow Pool, Level, and Schedule overrides.
1052 - Enhance cancel to timeout BSOCK packets after a specific delay.
1053 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1054 ua_status.!!! Thanks to Alan Brown for this tip.
1055 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1056 correctly for multiple simultaneous jobs.
1057 - Correct code so that FileSet MD5 is calculated for < and | filename
1059 - Implement the Media record flag that indicates that the Volume does disk
1061 - Implement VolAddr, which is used when Volume is addressed like a disk,
1062 and form it from VolFile and VolBlock.
1063 - Make multiple restore jobs for multiple media types specifying
1064 the proper storage type.
1065 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1066 pointer (rec) to try_repositioning().
1067 - Look at extracting Win data from BackupRead.
1068 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1069 which would take precidence over the Catalog "JobRetention".
1070 - Implement Label Format in Add and Label console commands.
1071 - Possibly up network buffers to 65K. Put on variable.
1072 - Put email tape request delays on one or more variables. User wants
1073 to cancel the job after a certain time interval. Maximum Mount Wait?
1074 - Job, Client, Device, Pool, or Volume?
1075 Is it possible to make this a directive which is *optional* in multiple
1076 resources, like Level? If so, I think I'd make it an optional directive
1077 in Job, Client, and Pool, with precedence such that Job overrides Client
1078 which in turn overrides Pool.
1080 - New Storage specifications:
1081 - Want to write to multiple storage devices simultaneously
1082 - Want to write to multiple storage devices sequentially (in one job)
1083 - Want to read/write simultaneously
1084 - Key is MediaType -- it must match
1086 Passed to SD as a sort of BSR record called Storage Specification
1090 MediaType -> Next MediaType
1092 Device -> Next Device
1094 Allow multiple Storage specifications
1102 Allow Multiple Pool specifications (note, Pool currently
1104 Allow Multiple MediaType specifications in Dir conf
1105 Allow Multiple Device specifications in Dir conf
1106 Perhaps keep this in a single SSR
1107 Tie a Volume to a specific device by using a MediaType that
1108 is contained in only one device.
1109 In SD allow Device to have Multiple MediaTypes
1111 - Ideas from Jerry Scharf:
1112 First let's point out some big pluses that bacula has for this
1114 more importantly it's active. Thank you so much for that
1115 even more important, it's not flaky
1116 it has an open access catalog, opening many possibilities
1117 it's pushing toward heterogeneous systems capability
1119 Macintosh file client
1120 macs are an interesting niche, but I fear a server is a rathole
1121 working bare iron recovery for windows
1122 the option for inc/diff backups not reset on fileset revision
1123 a) use both change and inode update time against base time
1124 b) do the full catalog check (expensive but accurate)
1125 sizing guide (how much system is needed to back up N systems/files)
1126 consultants on using bacula in building a disaster recovery system
1127 an integration guide
1128 or how to get at fancy things that one could do with bacula
1129 logwatch code for bacula logs (or similar)
1130 linux distro inclusion of bacula (brings good and bad, but necessary)
1131 win2k/XP server capability (icky but you asked)
1132 support for Oracle database ??
1134 - Look at adding SQL server and Exchange support for Windows.
1135 - Make dev->file and dev->block_num signed integers so that -1 can
1136 be an invalid value which happens with BSR.
1137 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1138 is needed to properly specify ranges.
1139 - Add progress of files/bytes to SD and FD.
1140 - Print warning message if FileId > 4 billion
1141 - do a "messages" before the first prompt in Console
1142 - Client does not show busy during Estimate command.
1143 - Implement Console mtx commands.
1144 - Implement a Mount Command and an Unmount Command where
1145 the users could specify a system command to be performed
1146 to do the mount, after which Bacula could attempt to
1147 read the device. This is for Removeable media such as a CDROM.
1148 - Most likely, this mount command would be invoked explicitly
1149 by the user using the current Console "mount" and "unmount"
1150 commands -- the Storage Daemon would do the right thing
1151 depending on the exact nature of the device.
1152 - As with tape drives, when Bacula wanted a new removable
1153 disk mounted, it would unmount the old one, and send a message
1154 to the user, who would then use "mount" as described above
1155 once he had actually inserted the disk.
1156 - Implement dump/print label to UA
1157 - Spool to disk only when the tape is full, then when a tape is hung move
1159 - bextract is sending everything to the log file ****FIXME****
1160 - Allow multiple Storage specifications (or multiple names on
1161 a single Storage specification) in the Job record. Thus a job
1162 can be backed up to a number of storage devices.
1163 - Implement some way for the File daemon to contact the Director
1164 to start a job or pass its DHCP obtained IP number.
1165 - Implement a query tape prompt/replace feature for a console
1166 - Copy console @ code to gnome2-console
1167 - Make tree walk routines like cd, ls, ... more user friendly
1168 by handling spaces better.
1169 - Make sure that Bacula rechecks the tape after the 20 min wait.
1170 - Set IO_NOWAIT on Bacula TCP/IP packets.
1171 - Try doing a raw partition backup and restore by mounting a
1173 - From Lars Kellers:
1174 Yes, it would allow to highly automatic the request for new tapes. If a
1175 tape is empty, bacula reads the barcodes (native or simulated), and if
1176 an unused tape is found, it runs the label command with all the
1177 necessary parameters.
1179 By the way can bacula automatically "move" an empty/purged volume say
1180 in the "short" pool to the "long" pool if this pool runs out of volume
1182 - What to do about "list files job=xxx".
1183 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1184 file descriptor leak in Bacula.
1185 - Implement WrapCounters in Counters.
1186 - Add heartbeat from FD to SD if hb interval expires.
1187 - Can we dynamically change FileSets?
1188 - If pool specified to label command and Label Format is specified,
1189 automatically generate the Volume name.
1190 - Why can't SQL do the filename sort for restore?
1191 - Add ExhautiveRestoreSearch
1192 - Look at the possibility of loading only the necessary
1193 data into the restore tree (i.e. do it one directory at a
1194 time as the user walks through the tree).
1195 - Possibly use the hash code if the user selects all for a restore command.
1196 - Fix "restore all" to bypass building the tree.
1197 - Prohibit backing up archive device (findlib/find_one.c:128)
1198 - Implement Release Device in the Job resource to unmount a drive.
1199 - Implement Acquire Device in the Job resource to mount a drive,
1200 be sure this works with admin jobs so that the user can get
1201 prompted to insert the correct tape. Possibly some way to say to
1202 run the job but don't save the files.
1203 - Make things like list where a file is saved case independent for
1205 - Use autochanger to handle multiple devices.
1206 - Implement a Recycle command
1207 - Start working on Base jobs.
1208 - Implement UnsavedFiles DB record.
1209 - From Phil Stracchino:
1210 It would probably be a per-client option, and would be called
1211 something like, say, "Automatically purge obsoleted jobs". What it
1212 would do is, when you successfully complete a Differential backup of a
1213 client, it would automatically purge all Incremental backups for that
1214 client that are rendered redundant by that Differential. Likewise,
1215 when a Full backup on a client completed, it would automatically purge
1216 all Differential and Incremental jobs obsoleted by that Full backup.
1217 This would let people minimize the number of tapes they're keeping on
1218 hand without having to master the art of retention times.
1219 - When doing a Backup send all attributes back to the Director, who
1220 would then figure out what files have been deleted.
1221 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1222 explicit permission to do so. It should also mark the tape in error
1223 if there is an error.
1224 - Cancel waiting for Client connect in SD if FD goes away.
1226 - Implement timeout in response() when it should come quickly.
1227 - Implement a Slot priority (loaded/not loaded).
1228 - Implement "vacation" Incremental only saves.
1229 - Implement create "FileSet"?
1230 - Add prefixlinks to where or not where absolute links to FD.
1231 - Issue message to mount a new tape before the rewind.
1232 - Simplified client job initiation for portables.
1233 - If SD cannot open a drive, make it periodically retry.
1234 - Add more of the config info to the tape label.
1236 - Refine SD waiting output:
1237 Device is being positioned
1238 > Device is being positioned for append
1239 > Device is being positioned to file x
1241 - Figure out some way to estimate output size and to avoid splitting
1242 a backup across two Volumes -- this could be useful for writing CDROMs
1243 where you really prefer not to have it split -- not serious.
1244 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1245 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1246 actual data on the Volume and compare it.
1247 - Implement Bacula plugins -- design API
1248 - Make bcopy read through bad tape records.
1249 - Program files (i.e. execute a program to read/write files).
1250 Pass read date of last backup, size of file last time.
1251 - Add Signature type to File DB record.
1252 - CD into subdirectory when open()ing files for backup to
1253 speed up things. Test with testfind().
1254 - Priority job to go to top of list.
1255 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1256 - Implement some way for the Console to dynamically create a job.
1257 - Solaris -I on tar for include list
1258 - Need a verbose mode in restore, perhaps to bsr.
1259 - bscan without -v is too quiet -- perhaps show jobs.
1260 - Add code to reject whole blocks if not wanted on restore.
1261 - Check if we can increase Bacula FD priorty in Win2000
1262 - Make sure the MaxVolFiles is fully implemented in SD
1263 - Check if both CatalogFiles and UseCatalog are set to SD.
1264 - Possibly add email to Watchdog if drive is unmounted too
1265 long and a job is waiting on the drive.
1266 - After unmount, if restore job started, ask to mount.
1267 - Add UA rc and history files.
1268 - put termcap (used by console) in ./configure and
1269 allow -with-termcap-dir.
1270 - Fix Autoprune for Volumes to respect need for full save.
1271 - Compare tape to Client files (attributes, or attributes and data)
1272 - Make all database Ids 64 bit.
1273 - Allow console commands to detach or run in background.
1274 - Add SD message variables to control operator wait time
1275 - Maximum Operator Wait
1276 - Minimum Message Interval
1277 - Maximum Message Interval
1278 - Send Operator message when cannot read tape label.
1279 - Verify level=Volume (scan only), level=Data (compare of data to file).
1280 Verify level=Catalog, level=InitCatalog
1282 - Add keyword search to show command in Console.
1283 - Events : tape has more than xxx bytes.
1284 - Complete code in Bacula Resources -- this will permit
1285 reading a new config file at any time.
1286 - Handle ctl-c in Console
1287 - Implement script driven addition of File daemon to config files.
1288 - Think about how to make Bacula work better with File (non-tape) archives.
1289 - Write Unix emulator for Windows.
1290 - Put memory utilization in Status output of each daemon
1291 if full status requested or if some level of debug on.
1292 - Make database type selectable by .conf files i.e. at runtime
1293 - Set flag for uname -a. Add to Volume label.
1294 - Restore files modified after date
1295 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1296 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1297 - Timout a job or terminate if link goes down, or reopen link and query.
1298 - Concept of precious tapes (cannot be reused).
1299 - Make bcopy copy with a single tape drive.
1300 - Permit changing ownership during restore.

1314 - Autolabel should be specified by DIR instead of SD.
1316 - Add media capacity
1317 - AutoScan (check checksum of tape)
1318 - Format command = "format /dev/nst0"
1322 - Seek resolution (usually corresponds to buffer size)
1323 - EODErrorCode=ENOSPC or code
1324 - Partial Read error code
1325 - Partial write error code
1326 - Nonformatted read error
1327 - Nonformatted write error

1342 - FD sends unsaved file list to Director at end of job (see
1344 - File daemon should build list of files skipped, and then
1345 at end of save retry and report any errors.
1346 - Write a Storage daemon that uses pipes and
1347 standard Unix programs to write to the tape.
1349 - Need something that monitors the JCR queue and
1350 times out jobs by asking the deamons where they are.
1351 - Enhance Jmsg code to permit buffering and saving to disk.
1352 - device driver = "xxxx" for drives.
1353 - Verify from Volume
1354 - Ensure that /dev/null works
1355 - Need report class for messages. Perhaps
1356 report resource where report=group of messages
1357 - enhance scan_attrib and rename scan_jobtype, and
1358 fill in code for "since" option
1359 - Director needs a time after which the report status is sent
1360 anyway -- or better yet, a retry time for the job.
1361 - Don't reschedule a job if previous incarnation is still running.
1362 - Some way to automatically backup everything is needed????
1363 - Need a structure for pending actions:
1365 - termination status (part of buffered msgs?)
1367 Read, Write, Clean, Delete
1368 - Login to Bacula; Bacula users with different permissions:
1369 owner, group, user, quotas
1370 - Store info on each file system type (probably in the job header on tape.
1371 This could be the output of df; or perhaps some sort of /etc/mtab record.
1373 ========= ideas ===============
1374 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1375 To: <kern@sibbald.com>
1376 Subject: RE: [Bacula-users] future large programming jobs
1377 Date: Thu, 26 Feb 2004 11:34:54 -0600
1379 I noticed the subject thread and thought I would offer the following
1380 merely as sources of ideas, i.e. something to think about, not even as
1381 strong as a request. In my former life (before retiring) I often
1382 dealt with backups and storage management issues/products as a
1383 developer and as a consultant. I am currently migrating my personal
1384 network from amanda to bacula specifically because of the ability to
1385 cross media boundaries during storing backups.
1386 Are you familiar with the commercial product called ADSM (I think IBM
1387 now sells it under the Tivoli label)? It has a couple of interesting
1388 ideas that may apply to the following topics.
1390 1. Migration: Consider that when you need to restore a system, there
1391 may be pressure to hurry. If all the information for a single client
1392 can eventually end up on the same media (and in chronological order),
1393 the restore is facillitated by not having to search past information
1394 from other clients. ADSM has the concept of "client affinity" that
1395 may be associated with it's storage pools. It seems to me that this
1396 concept (as an optional feature) might fit in your architecture for
1399 ADSM also has the concept of defining one or more storage pools as
1400 "copy pools" (almost mirrors, but only in the sense of contents).
1401 These pools provide the ability to have duplicte data stored both
1402 onsite and offsite. The copy process can be scheduled to be handled
1403 by their storage manager during periods when there is no backup
1404 activity. Again, the migration process might be a place to consider
1405 implementing something like this.
1408 > It strikes me that it would be very nice to be able to do things
1410 > have the Job(s) backing up the machines run, and once they have all

1416 > mechanism described below would probably make it very easy.
1418 This is the goal. In the first step (before events), you simply
1420 the Migration to tape later.
1422 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1423 the database. Once a file (unique by path and metadata such as dates,
1424 size, ownership, etc.) is in a copy pool, no more copies are made. In
1425 other words, when you start ADSM, it begins like your concept of a
1426 base job. After that it is in the "incremental" mode. You can
1427 configure the number of "generations" of files to be retained, plus a
1428 retention date after which even old generations are purged. The
1429 database tracks the contents of media and projects the percentage of
1430 each volume that is valid. When the valid content of a volume drops
1431 below a configured percentage, the valid data are migrated to another
1432 volume and the old volume is marked as empty. Note, this requires
1433 ADSM to have an idea of the contents of a client, i.e. marking the
1434 database when an existing file was deleted, but this would solve your
1435 issue of restoring a client without restoring deleted files.
1437 This is pretty far from what bacula now does, but if you are going to
1438 rip things up for Base jobs,.....
1439 Also, the benefits of this are huge for very large shops, especially
1440 with media robots, but are a pain for shops with manual media
1444 > Base jobs sound pretty useful, but I'm not dying for them.
1446 Nobody is dying for them, but when you see what it does, you will die
1449 3. Restoring deleted files: Since I think my comments in (2) above
1450 have low probability of implementation, I'll also suggest that you
1451 could approach the issue of deleted files by a mechanism of having the
1452 fd report to the dir, a list of all files on the client for every
1453 backup job. The dir could note in the database entry for each file
1454 the date that the file was seen. Then if a restore as of date X takes
1455 place, only files that exist from before X until after X would be
1456 restored. Probably the major cost here is the extra date container in
1457 each row of the files table.
1459 Thanks for "listening". I hope some of this helps. If you want to
1460 contact me, please send me an email - I read some but not all of the
1461 mailing list traffic and might miss a reply there.
1463 Please accept my compliments for bacula. It is doing a great job for
1464 me!! I sympathize with you in the need to wrestle with excelence in
1465 execution vs. excelence in feature inclusion.
1470 ==============================
1473 - Design at hierarchial storage for Bacula. Migration and Clone.
1474 - Implement FSM (File System Modules).
1475 - Audit M_ error codes to ensure they are correct and consistent.
1476 - Add variable break characters to lex analyzer.
1477 Either a bit mask or a string of chars so that
1478 the caller can change the break characters.
1479 - Make a single T_BREAK to replace T_COMMA, etc.
1480 - Ensure that File daemon and Storage daemon can
1481 continue a save if the Director goes down (this
1482 is NOT currently the case). Must detect socket error,
1483 buffer messages for later.
1484 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1485 - Add ability to backup to two Storage devices (two SD sessions) at
1486 the same time -- e.g. onsite, offsite.
1487 - Add the ability to consolidate old backup sets (basically do a restore
1488 to tape and appropriately update the catalog). Compress Volume sets.
1489 Might need to spool via file is only one drive is available.
1490 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1491 someway to do so with every volume that has less than x% valid
1495 Migration: Move a backup from one Volume to another
1496 Clone: Copy a backup -- two Volumes
1499 ======================================================
1501 It is somewhat like a Full save becomes an incremental since
1502 the Base job (or jobs) plus other non-base files.
1504 - A Base backup is same as Full backup, just different type.
1505 - New BaseFiles table that contains:
1507 BaseJobId - Base JobId referenced for this FileId (needed ???)
1508 JobId - JobId currently running
1509 FileId - File not backed up, exists in Base Job
1510 FileIndex - FileIndex from Base Job.
1511 i.e. for each base file that exists but is not saved because
1512 it has not changed, the File daemon sends the JobId, BaseId,
1513 FileId, FileIndex back to the Director who creates the DB entry.
1514 - To initiate a Base save, the Director sends the FD
1515 the FileId, and full filename for each file in the Base.
1516 - When the FD finds a Base file, he requests the Director to
1517 send him the full File entry (stat packet plus MD5), or
1518 conversely, the FD sends it to the Director and the Director
1519 says yes or no. This can be quite rapid if the FileId is kept
1520 by the FD for each Base Filename.
1521 - It is probably better to have the comparison done by the FD
1522 despite the fact that the File entry must be sent across the
1524 - An alternative would be to send the FD the whole File entry
1525 from the start. The disadvantage is that it requires a lot of
1526 space. The advantage is that it requires less communications
1528 - The Job record must be updated to indicate that one or more
1530 - At end of Job, FD returns:
1531 1. Count of base files/bytes not written to tape (i.e. matches)
1532 2. Count of base file that were saved i.e. had changed.
1533 - No tape record would be written for a Base file that matches, in the
1534 same way that no tape record is written for Incremental jobs where
1535 the file is not saved because it is unchanged.
1536 - On a restore, all the Base file records must explicitly be
1537 found from the BaseFile tape. I.e. for each Full save that is marked
1538 to have one or more Base Jobs, search the BaseFile for all occurrences
1540 - An optimization might be to make the BaseFile have:
1546 This would avoid the need to explicitly fetch each File record for
1547 the Base job. The Base Job record will be fetched to get the
1548 VolSessionId and VolSessionTime.
1549 =========================================================
1552 ==========================================================
1554 For each Incremental job that is run, there may be files that
1555 were found but not saved because they were locked (this applies
1556 only to Windows). Such a system could send back to the Director
1557 a list of Unsaved files.
1559 - New UnSavedFiles table that contains:
1563 - Then in the next Incremental job, the list of Unsaved Files will be
1564 feed to the FD, who will ensure that they are explicitly chosen even
1565 if standard date/time check would not have selected them.

1610 There needs to be a table of drive # to devices somewhere - If there are
1611 multiple changers or drives there may not be a 1:1 correspondance between
1612 changer drive number and system device name - and depending on the way the
1613 drives are hooked up to scsi busses, they may not be linearly numbered
1614 from an offset point either.something like
1616 Autochanger drives = 2
1617 Autochanger drive 0 = /dev/nst1
1618 Autochanger drive 1 = /dev/nst2
1619 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1620 times, not just for multidrive changers. For a 1 drive changer, that's
1626 MTX's manpage (1.2.15):
1627 unload [<slotnum>] [ <drivenum> ]
1628 Unloads media from drive <drivenum> into slot
1629 <slotnum>. If <drivenum> is omitted, defaults to
1630 drive 0 (as do all commands). If <slotnum> is
1631 omitted, defaults to the slot that the drive was
1632 loaded from. Note that there's currently no way
1633 to say 'unload drive 1's media to the slot it
1634 came from', other than to explicitly use that
1635 slot number as the destination.AB

1673 Handling removable disks
1675 From: Karl Cunningham <karlc@keckec.com>
1677 My backups are only to hard disk these days, in removable bays. This is my
1678 idea of how a backup to hard disk would work more smoothly. Some of these
1679 things Bacula does already, but I mention them for completeness. If others
1680 have better ways to do this, I'd like to hear about it.
1682 1. Accommodate several disks, rotated similar to how tapes are. Identified
1683 by partition volume ID or perhaps by the name of a subdirectory.
1684 2. Abort & notify the admin if the wrong disk is in the bay.
1685 3. Write backups to different subdirectories for each machine to be backed
1687 4. Volumes (files) get created as needed in the proper subdirectory, one
1689 5. When a disk is recycled, remove or zero all old backup files. This is
1690 important as the disk being recycled may be close to full. This may be
1691 better done manually since the backup files for many machines may be
1692 scattered in many subdirectories.
1697 - Why the heck doesn't bacula drop root priviledges before connecting to
1699 - Look at using posix_fadvise(2) for backups -- see bug #751.
