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

198 - It appears to me that you have run into some sort of race
199 condition where two threads want to use the same Volume and they
200 were both given access. Normally that is no problem. However,
201 one thread wanted the particular Volume in drive 0, but it was
202 loaded into drive 1 so it decided to unload it from drive 1 and
203 then loaded it into drive 0, while the second thread went on
204 thinking that the Volume could be used in drive 1 not realizing
205 that in between time, it was loaded in drive 0.
206 I'll look at the code to see if there is some way we can avoid
207 this kind of problem. Probably the best solution is to make the
208 first thread simply start using the Volume in drive 1 rather than
209 transferring it to drive 0.
210 - Fix re-read of last block to check if job has actually written
211 a block, and check if block was written by a different job
212 (i.e. multiple simultaneous jobs writing).
213 - Figure out how to configure query.sql. Suggestion to use m4:
214 == changequote.m4 ===

216 ==== query.sql.in ===
217 :List next 20 volumes to expire
219 Pool.Name AS PoolName,
224 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
226 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
230 ON Media.PoolId=Pool.PoolId
231 WHERE Media.LastWritten>0
235 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
237 The problem is that it requires m4, which is not present on all machines
239 - Given all the problems with FIFOs, I think the solution is to do something a
240 little different, though I will look at the code and see if there is not some
241 simple solution (i.e. some bug that was introduced). What might be a better
242 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
243 write data to a program rather than the FIFO. For example, suppose you
248 Then, I could imagine if you backup and restore this file with a direct
249 reference as is currently done for fifos, instead, during backup Bacula will
252 /home/kern/my-fifo.backup
254 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
257 /home/kern/my-fifo.restore
259 and send the data backed up to stdout. These programs can either be an
260 executable or a shell script and they need only read/write to stdin/stdout.
262 I think this would give a lot of flexibility to the user without making any
263 significant changes to Bacula.
268 select FilenameId from Filename where Name='';

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

457 - The btape fill command does not seem to use the Autochanger
458 - Make Windows installer default to system disk drive.

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

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

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

761 === From Carsten Menke <bootsy52@gmx.net>
763 Following is a list of what I think in the situations where I'm faced with,
764 could be a usefull enhancement to bacula, which I'm certain other users will
765 benefit from as well.
767 1. NextJob/NextJobs Directive within a Job Resource in the form of
768 NextJobs = job1,job2.
771 I currently solved the problem with running multiple jobs each after each
772 by setting the Max Wait Time for a job to 8 hours, and give
773 the jobs different Priorities. However, there scenarios where
774 1 Job is directly depending on another job, so if the former job fails,
775 the job after it needn't to be run
776 while maybe other jobs should run despite of that
779 A Backup Job and a Verify job, if the backup job fails there is no need to run
780 the verify job, as the backup job already failed. However, one may like
781 to backup the Catalog to disk despite of that the main backup job failed.
784 I see that this is related to the Event Handlers which are on the ToDo
785 list, also it is maybe a good idea to check for the return value and
786 execute different actions based on the return value
789 3. offline capability to bconsole
792 Currently I use a script which I execute within the last Job via the
793 RunAfterJob Directive, to release and eject the tape.
794 So I have to call bconsole "release=Storage-Name" and afterwards
795 mt -f /dev/nst0 eject to get the tape out.
797 If I have multiple Storage Devices, than these may not be /dev/nst0 and
798 I have to modify the script or call it with parameters etc.
799 This would actually not be needed, as everything is already defined
800 in bacula-sd.conf and if I can invoke bconsole with the
801 storage name via $1 in the script than I'm done and information is
804 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
808 For the reason mentioned in 3. to have the ability to call a
809 script with /scripts/foobar %s and in the script use $1
810 to pass the Storage Name to bconsole
812 5. Setting Volume State within a Job Resource
815 Instead of using "Maximum Volume Jobs" in the Pool Resource,
816 I would have the possibilty to define
817 in a Job Resource that after this certain job is run, the Volume State
818 should be set to "Volume State = Used", this give more flexibility (IMHO).
820 6. Localization of Bacula Messages
823 Unfortunatley many,many people I work with don't speak english very well.
824 So if at least the Reporting messages would be localized then they
825 would understand that they have to change the tape,etc. etc.
827 I volunteer to do the german translations, and if I can convince my wife also
828 french and Morre (western african language).
830 7. OK, this is evil, probably bound to security risks and maybe not possible
831 due to the design of bacula.
833 Implementation of Backtics ( `command` ) for shell comand execution to
834 the "Label Format" Directive.
838 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
839 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
840 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
841 the localized name for the day of the week appended to the
842 format string. Then I have the tape labeled automatically with weekday
843 name in the correct language.
845 - Yes, that is surely the case. I probably should turn those into Warning
846 errors. In addition, you just made me think that it might not be bad to
847 add an option to check the file size after backing up the file and
848 report if it changes. This would be done as an option because it would
851 Kern, good idea. If you do do that, mention in the output: file
852 shrunk, or file expanded, just to make it obvious to the user
853 (without having to the refer to file size), just how the file size
856 Would this option be for all file, or just one file? Or a fileset?
857 - Make output from status use html table tags for nicely
858 presenting in a browser.
859 - Can one write tapes faster with 8192 byte block sizes?
860 - Document security problems with the same password for everyone in
861 rpm and Win32 releases.
862 - Browse generations of files.
863 - I've seen an error when my catalog's File table fills up. I
864 then have to recreate the File table with a larger maximum row
865 size. Relevant information is at
866 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
867 "Installing and Configuring MySQL" chapter should talk a bit
868 about this potential problem, and recommend a solution.
869 - For Solaris must use POSIX awk.
870 - Want speed of writing to tape while despooling.
871 - Supported autochanger:
879 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
880 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
881 - Add regex from http://www.pcre.org to Bacula for Win32.
882 - Use only shell tools no make in CDROM package.
883 - Include within include does it work?
884 - Implement a Pool of type Cleaning?
885 - Implement VolReadTime and VolWriteTime in SD
886 - Modify Backing up Your Database to include a bootstrap file.
887 - Think about making certain database errors fatal.
888 - Look at correcting the time jump in the scheduler for daylight
889 savings time changes.
890 - Add a "real" timer to network connections.
891 - Promote to Full = Time period
892 - Check dates entered by user for correctness (month/day/... ranges)
893 - Compress restore Volume listing by date and first file.
894 - Look at patches/bacula_db.b2z postgresql that loops during restore.
896 - Perhaps add read/write programs and/or plugins to FileSets.
897 - How to handle backing up portables ...
898 - Add some sort of guaranteed Interval for upgrading jobs.
899 - Can we write the state file after every job terminates? On Win32
900 the system crashes and the state file is not updated.
903 Documentation to do: (any release a little bit at a time)
904 - Doc to do unmount before removing magazine.
905 - Alternative to static linking "ldd prog" save all binaries listed,
906 restore them and point LD_LIBRARY_PATH to them.
907 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
908 - Document query file format.
909 - Add more documentation for bsr files.
910 - Document problems with Verify and pruning.
911 - Document how to use multiple databases.
912 - VXA drives have a "cleaning required"
913 indicator, but Exabyte recommends preventive cleaning after every 75
916 In this context, it should be noted that Exabyte has a command-line
917 vxatool utility available for free download. (The current version is
918 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
919 test the drive, unload tapes, change drive settings, flash new firmware,
921 Of particular interest in this context is that vxatool <device> -i will
922 report, among other details, the time since last cleaning in tape motion
923 minutes. This information can be retrieved (and settings changed, for
924 that matter) through the generic-SCSI device even when Bacula has the
925 regular tape device locked. (Needless to say, I don't recommend
926 changing tape settings while a job is running.)
927 - Lookup HP cleaning recommendations.
928 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
929 - Document doing table repair
932 ===================================
933 - Add macro expansions in JobDefs.
934 Run Before Job = "SomeFile %{Level} %{Client}"
935 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
936 - Use non-blocking network I/O but if no data is available, use
938 - Use gather write() for network I/O.
939 - Autorestart on crash.
940 - Add bandwidth limiting.
941 - Add acks every once and a while from the SD to keep
942 the line from timing out.
943 - When an error in input occurs and conio beeps, you can back
944 up through the prompt.
945 - Detect fixed tape block mode during positioning by looking at
946 block numbers in btape "test". Possibly adjust in Bacula.
947 - Fix list volumes to output volume retention in some other
948 units, perhaps via a directive.
949 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
950 with multiple priorities.
951 - If you use restore replace=never, the directory attributes for
952 non-existent directories will not be restored properly.
954 - see lzma401.zip in others directory for new compression
956 - Allow the user to select JobType for manual pruning/purging.
957 - bscan does not put first of two volumes back with all info in
959 - Implement the FreeBSD nodump flag in chflags.
960 - Figure out how to make named console messages go only to that
961 console and to the non-restricted console (new console class?).
962 - Make restricted console prompt for password if *ask* is set or
963 perhaps if password is undefined.
964 - Implement "from ISO-date/time every x hours/days/weeks/months" in
967 ==== from Marc Schoechlin
968 - the help-command should be more verbose
969 (it should explain the paramters of the different
971 -> its time-comsuming to consult the manual anytime
972 you need a special parameter
973 -> maybe its more easy to maintain this, if the
974 descriptions of that commands are outsourced to
976 - the cd-command should allow complete paths
977 i.e. cd /foo/bar/foo/bar
978 -> if a customer mails me the path to a certain file,
979 its faster to enter the specified directory
980 - if the password is not configured in bconsole.conf
981 you should be asked for it.
982 -> sometimes you like to do restore on a customer-machine
983 which shouldnt know the password for bacula.
984 -> adding the password to the file favours admins
985 to forget to remove the password after usage
987 the protection of that file is less important
988 - long-listed-output of commands should be scrollable
989 like the unix more/less-command does
990 -> if someone runs 200 and more machines, the lists could
991 be a little long and complex
992 - command-output should be shown column by column
993 to reduce scrolling and to increase clarity
995 - lsmark should list the selected files with full
997 - wildcards for selecting and file and directories would be nice
998 - any actions should be interuptable with STRG+C
999 - command-expansion would be pretty cool
1001 - When the replace Never option is set, new directory permissions
1002 are not restored. See bug 213. To fix this requires creating a
1003 list of newly restored directories so that those directory
1004 permissions *can* be restored.
1005 - Add prune all command
1006 - Document fact that purge can destroy a part of a restore by purging
1007 one volume while others remain valid -- perhaps mark Jobs.
1008 - Add multiple-media-types.txt
1009 - look at mxt-changer.html
1010 - Make ? do a help command (no return needed).
1011 - Implement restore directory.
1012 - Document streams and how to implement them.
1013 - Try not to re-backup a file if a new hard link is added.
1014 - Add feature to backup hard links only, but not the data.
1015 - Fix stream handling to be simpler.
1016 - Add Priority and Bootstrap to Run a Job.
1017 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1019 - Remove View FileSet button from Run a Job dialog.
1020 - Handle prompt for restore job at end of Restore command.
1021 - Add display of total selected files to Restore window.
1022 - Add tree pane to left of window.
1023 - Add progress meter.
1024 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1025 - Add message to user to check for fixed block size when the forward
1026 space test fails in btape.
1027 - When unmarking a directory check if all files below are unmarked and
1028 then remove the + flag -- in the restore tree.
1029 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1030 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1031 - Revisit the question of multiple Volumes (disk) on a single device.
1032 - Add a block copy option to bcopy.
1033 - Finish work on Gnome restore GUI.
1034 - Fix "llist jobid=xx" where no fileset or client exists.
1035 - For each job type (Admin, Restore, ...) require only the really necessary
1036 fields.- Pass Director resource name as an option to the Console.
1037 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1038 - Add a .list all files in the restore tree (probably also a list all files)
1039 Do both a long and short form.
1040 - Allow browsing the catalog to see all versions of a file (with
1041 stat data on each file).
1042 - Restore attributes of directory if replace=never set but directory
1044 - Use SHA1 on authentication if possible.
1045 - See comtest-xxx.zip for Windows code to talk to USB.
1046 - Add John's appended files:
1047 Appended = { /files/server/logs/http/*log }
1048 and such files would be treated as follows.On a FULL backup, they would
1049 be backed up like any other file.On an INCREMENTAL backup, where a
1050 previous INCREMENTAL or FULL was already in thecatalogue and the length
1051 of the file wasgreater than the length of the last backup, only thedata
1052 added since the last backup will be dumped.On an INCREMENTAL backup, if
1053 the length of the file is less than thelength of the file with the same
1054 name last backed up, the completefile is dumped.On Windows systems, with
1055 creation date of files, we can be evensmarter about this and not count
1056 entirely upon the length.On a restore, the full and all incrementals
1057 since it will beapplied in sequence to restore the file.
1058 - Check new HAVE_WIN32 open bits.
1059 - Check if the tape has moved before writing.
1060 - Handling removable disks -- see below:
1061 - Keep track of tape use time, and report when cleaning is necessary.
1062 - Add FromClient and ToClient keywords on restore command (or
1063 BackupClient RestoreClient).
1064 - Implement a JobSet, which groups any number of jobs. If the
1065 JobSet is started, all the jobs are started together.
1066 Allow Pool, Level, and Schedule overrides.
1067 - Enhance cancel to timeout BSOCK packets after a specific delay.
1068 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1069 ua_status.!!! Thanks to Alan Brown for this tip.
1070 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1071 correctly for multiple simultaneous jobs.
1072 - Correct code so that FileSet MD5 is calculated for < and | filename
1074 - Implement the Media record flag that indicates that the Volume does disk
1076 - Implement VolAddr, which is used when Volume is addressed like a disk,
1077 and form it from VolFile and VolBlock.
1078 - Make multiple restore jobs for multiple media types specifying
1079 the proper storage type.
1080 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1081 pointer (rec) to try_repositioning().
1082 - Look at extracting Win data from BackupRead.
1083 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1084 which would take precidence over the Catalog "JobRetention".
1085 - Implement Label Format in Add and Label console commands.
1086 - Possibly up network buffers to 65K. Put on variable.
1087 - Put email tape request delays on one or more variables. User wants
1088 to cancel the job after a certain time interval. Maximum Mount Wait?
1089 - Job, Client, Device, Pool, or Volume?
1090 Is it possible to make this a directive which is *optional* in multiple
1091 resources, like Level? If so, I think I'd make it an optional directive
1092 in Job, Client, and Pool, with precedence such that Job overrides Client
1093 which in turn overrides Pool.
1095 - New Storage specifications:
1096 - Want to write to multiple storage devices simultaneously
1097 - Want to write to multiple storage devices sequentially (in one job)
1098 - Want to read/write simultaneously
1099 - Key is MediaType -- it must match
1101 Passed to SD as a sort of BSR record called Storage Specification
1105 MediaType -> Next MediaType
1107 Device -> Next Device
1109 Allow multiple Storage specifications
1117 Allow Multiple Pool specifications (note, Pool currently
1119 Allow Multiple MediaType specifications in Dir conf
1120 Allow Multiple Device specifications in Dir conf
1121 Perhaps keep this in a single SSR
1122 Tie a Volume to a specific device by using a MediaType that
1123 is contained in only one device.
1124 In SD allow Device to have Multiple MediaTypes
1126 - Ideas from Jerry Scharf:
1127 First let's point out some big pluses that bacula has for this
1129 more importantly it's active. Thank you so much for that
1130 even more important, it's not flaky
1131 it has an open access catalog, opening many possibilities
1132 it's pushing toward heterogeneous systems capability
1134 Macintosh file client
1135 macs are an interesting niche, but I fear a server is a rathole
1136 working bare iron recovery for windows
1137 the option for inc/diff backups not reset on fileset revision
1138 a) use both change and inode update time against base time
1139 b) do the full catalog check (expensive but accurate)
1140 sizing guide (how much system is needed to back up N systems/files)
1141 consultants on using bacula in building a disaster recovery system
1142 an integration guide
1143 or how to get at fancy things that one could do with bacula
1144 logwatch code for bacula logs (or similar)
1145 linux distro inclusion of bacula (brings good and bad, but necessary)
1146 win2k/XP server capability (icky but you asked)
1147 support for Oracle database ??
1149 - Look at adding SQL server and Exchange support for Windows.
1150 - Make dev->file and dev->block_num signed integers so that -1 can
1151 be an invalid value which happens with BSR.
1152 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1153 is needed to properly specify ranges.
1154 - Add progress of files/bytes to SD and FD.
1155 - Print warning message if FileId > 4 billion
1156 - do a "messages" before the first prompt in Console
1157 - Client does not show busy during Estimate command.
1158 - Implement Console mtx commands.
1159 - Implement a Mount Command and an Unmount Command where
1160 the users could specify a system command to be performed
1161 to do the mount, after which Bacula could attempt to
1162 read the device. This is for Removeable media such as a CDROM.
1163 - Most likely, this mount command would be invoked explicitly
1164 by the user using the current Console "mount" and "unmount"
1165 commands -- the Storage Daemon would do the right thing
1166 depending on the exact nature of the device.
1167 - As with tape drives, when Bacula wanted a new removable
1168 disk mounted, it would unmount the old one, and send a message
1169 to the user, who would then use "mount" as described above
1170 once he had actually inserted the disk.
1171 - Implement dump/print label to UA
1172 - Spool to disk only when the tape is full, then when a tape is hung move
1174 - bextract is sending everything to the log file ****FIXME****
1175 - Allow multiple Storage specifications (or multiple names on
1176 a single Storage specification) in the Job record. Thus a job
1177 can be backed up to a number of storage devices.
1178 - Implement some way for the File daemon to contact the Director
1179 to start a job or pass its DHCP obtained IP number.
1180 - Implement a query tape prompt/replace feature for a console
1181 - Copy console @ code to gnome2-console
1182 - Make tree walk routines like cd, ls, ... more user friendly
1183 by handling spaces better.
1184 - Make sure that Bacula rechecks the tape after the 20 min wait.
1185 - Set IO_NOWAIT on Bacula TCP/IP packets.
1186 - Try doing a raw partition backup and restore by mounting a
1188 - From Lars Kellers:
1189 Yes, it would allow to highly automatic the request for new tapes. If a
1190 tape is empty, bacula reads the barcodes (native or simulated), and if
1191 an unused tape is found, it runs the label command with all the
1192 necessary parameters.
1194 By the way can bacula automatically "move" an empty/purged volume say
1195 in the "short" pool to the "long" pool if this pool runs out of volume
1197 - What to do about "list files job=xxx".
1198 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1199 file descriptor leak in Bacula.
1200 - Implement WrapCounters in Counters.
1201 - Add heartbeat from FD to SD if hb interval expires.
1202 - Can we dynamically change FileSets?
1203 - If pool specified to label command and Label Format is specified,
1204 automatically generate the Volume name.
1205 - Why can't SQL do the filename sort for restore?
1206 - Add ExhautiveRestoreSearch
1207 - Look at the possibility of loading only the necessary
1208 data into the restore tree (i.e. do it one directory at a
1209 time as the user walks through the tree).
1210 - Possibly use the hash code if the user selects all for a restore command.
1211 - Fix "restore all" to bypass building the tree.
1212 - Prohibit backing up archive device (findlib/find_one.c:128)
1213 - Implement Release Device in the Job resource to unmount a drive.
1214 - Implement Acquire Device in the Job resource to mount a drive,
1215 be sure this works with admin jobs so that the user can get
1216 prompted to insert the correct tape. Possibly some way to say to
1217 run the job but don't save the files.
1218 - Make things like list where a file is saved case independent for
1220 - Use autochanger to handle multiple devices.
1221 - Implement a Recycle command
1222 - Start working on Base jobs.
1223 - Implement UnsavedFiles DB record.
1224 - From Phil Stracchino:
1225 It would probably be a per-client option, and would be called
1226 something like, say, "Automatically purge obsoleted jobs". What it
1227 would do is, when you successfully complete a Differential backup of a
1228 client, it would automatically purge all Incremental backups for that
1229 client that are rendered redundant by that Differential. Likewise,
1230 when a Full backup on a client completed, it would automatically purge
1231 all Differential and Incremental jobs obsoleted by that Full backup.
1232 This would let people minimize the number of tapes they're keeping on
1233 hand without having to master the art of retention times.
1234 - When doing a Backup send all attributes back to the Director, who
1235 would then figure out what files have been deleted.
1236 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1237 explicit permission to do so. It should also mark the tape in error
1238 if there is an error.
1239 - Cancel waiting for Client connect in SD if FD goes away.
1241 - Implement timeout in response() when it should come quickly.
1242 - Implement a Slot priority (loaded/not loaded).
1243 - Implement "vacation" Incremental only saves.
1244 - Implement create "FileSet"?
1245 - Add prefixlinks to where or not where absolute links to FD.
1246 - Issue message to mount a new tape before the rewind.
1247 - Simplified client job initiation for portables.
1248 - If SD cannot open a drive, make it periodically retry.
1249 - Add more of the config info to the tape label.
1251 - Refine SD waiting output:
1252 Device is being positioned
1253 > Device is being positioned for append
1254 > Device is being positioned to file x
1256 - Figure out some way to estimate output size and to avoid splitting
1257 a backup across two Volumes -- this could be useful for writing CDROMs
1258 where you really prefer not to have it split -- not serious.
1259 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1260 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1261 actual data on the Volume and compare it.
1262 - Implement Bacula plugins -- design API
1263 - Make bcopy read through bad tape records.
1264 - Program files (i.e. execute a program to read/write files).
1265 Pass read date of last backup, size of file last time.
1266 - Add Signature type to File DB record.
1267 - CD into subdirectory when open()ing files for backup to
1268 speed up things. Test with testfind().
1269 - Priority job to go to top of list.
1270 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1271 - Implement some way for the Console to dynamically create a job.
1272 - Solaris -I on tar for include list
1273 - Need a verbose mode in restore, perhaps to bsr.
1274 - bscan without -v is too quiet -- perhaps show jobs.
1275 - Add code to reject whole blocks if not wanted on restore.
1276 - Check if we can increase Bacula FD priorty in Win2000
1277 - Make sure the MaxVolFiles is fully implemented in SD
1278 - Check if both CatalogFiles and UseCatalog are set to SD.
1279 - Possibly add email to Watchdog if drive is unmounted too
1280 long and a job is waiting on the drive.
1281 - After unmount, if restore job started, ask to mount.
1282 - Add UA rc and history files.
1283 - put termcap (used by console) in ./configure and
1284 allow -with-termcap-dir.
1285 - Fix Autoprune for Volumes to respect need for full save.
1286 - Compare tape to Client files (attributes, or attributes and data)
1287 - Make all database Ids 64 bit.
1288 - Allow console commands to detach or run in background.
1289 - Add SD message variables to control operator wait time
1290 - Maximum Operator Wait
1291 - Minimum Message Interval
1292 - Maximum Message Interval
1293 - Send Operator message when cannot read tape label.
1294 - Verify level=Volume (scan only), level=Data (compare of data to file).
1295 Verify level=Catalog, level=InitCatalog
1297 - Add keyword search to show command in Console.
1298 - Events : tape has more than xxx bytes.
1299 - Complete code in Bacula Resources -- this will permit
1300 reading a new config file at any time.
1301 - Handle ctl-c in Console
1302 - Implement script driven addition of File daemon to config files.
1303 - Think about how to make Bacula work better with File (non-tape) archives.
1304 - Write Unix emulator for Windows.
1305 - Put memory utilization in Status output of each daemon
1306 if full status requested or if some level of debug on.
1307 - Make database type selectable by .conf files i.e. at runtime
1308 - Set flag for uname -a. Add to Volume label.
1309 - Restore files modified after date
1310 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1311 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1312 - Timout a job or terminate if link goes down, or reopen link and query.
1313 - Concept of precious tapes (cannot be reused).
1314 - Make bcopy copy with a single tape drive.
1315 - Permit changing ownership during restore.

1329 - Autolabel should be specified by DIR instead of SD.
1331 - Add media capacity
1332 - AutoScan (check checksum of tape)
1333 - Format command = "format /dev/nst0"
1337 - Seek resolution (usually corresponds to buffer size)
1338 - EODErrorCode=ENOSPC or code
1339 - Partial Read error code
1340 - Partial write error code
1341 - Nonformatted read error
1342 - Nonformatted write error
1343 - WriteProtected error
1347 - IgnoreCloseErrors=yes
1357 - FD sends unsaved file list to Director at end of job (see
1359 - File daemon should build list of files skipped, and then
1360 at end of save retry and report any errors.
1361 - Write a Storage daemon that uses pipes and
1362 standard Unix programs to write to the tape.
1364 - Need something that monitors the JCR queue and
1365 times out jobs by asking the deamons where they are.
1366 - Enhance Jmsg code to permit buffering and saving to disk.
1367 - device driver = "xxxx" for drives.
1368 - Verify from Volume
1369 - Ensure that /dev/null works
1370 - Need report class for messages. Perhaps
1371 report resource where report=group of messages
1372 - enhance scan_attrib and rename scan_jobtype, and
1373 fill in code for "since" option
1374 - Director needs a time after which the report status is sent
1375 anyway -- or better yet, a retry time for the job.
1376 - Don't reschedule a job if previous incarnation is still running.
1377 - Some way to automatically backup everything is needed????
1378 - Need a structure for pending actions:
1380 - termination status (part of buffered msgs?)
1382 Read, Write, Clean, Delete
1383 - Login to Bacula; Bacula users with different permissions:
1384 owner, group, user, quotas
1385 - Store info on each file system type (probably in the job header on tape.
1386 This could be the output of df; or perhaps some sort of /etc/mtab record.
1388 ========= ideas ===============
1389 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1390 To: <kern@sibbald.com>
1391 Subject: RE: [Bacula-users] future large programming jobs
1392 Date: Thu, 26 Feb 2004 11:34:54 -0600
1394 I noticed the subject thread and thought I would offer the following
1395 merely as sources of ideas, i.e. something to think about, not even as
1396 strong as a request. In my former life (before retiring) I often
1397 dealt with backups and storage management issues/products as a
1398 developer and as a consultant. I am currently migrating my personal
1399 network from amanda to bacula specifically because of the ability to
1400 cross media boundaries during storing backups.
1401 Are you familiar with the commercial product called ADSM (I think IBM
1402 now sells it under the Tivoli label)? It has a couple of interesting
1403 ideas that may apply to the following topics.
1405 1. Migration: Consider that when you need to restore a system, there
1406 may be pressure to hurry. If all the information for a single client
1407 can eventually end up on the same media (and in chronological order),
1408 the restore is facillitated by not having to search past information
1409 from other clients. ADSM has the concept of "client affinity" that
1410 may be associated with it's storage pools. It seems to me that this
1411 concept (as an optional feature) might fit in your architecture for
1414 ADSM also has the concept of defining one or more storage pools as
1415 "copy pools" (almost mirrors, but only in the sense of contents).
1416 These pools provide the ability to have duplicte data stored both
1417 onsite and offsite. The copy process can be scheduled to be handled
1418 by their storage manager during periods when there is no backup
1419 activity. Again, the migration process might be a place to consider
1420 implementing something like this.
1423 > It strikes me that it would be very nice to be able to do things
1425 > have the Job(s) backing up the machines run, and once they have all

1431 > mechanism described below would probably make it very easy.
1433 This is the goal. In the first step (before events), you simply
1435 the Migration to tape later.
1437 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1438 the database. Once a file (unique by path and metadata such as dates,
1439 size, ownership, etc.) is in a copy pool, no more copies are made. In
1440 other words, when you start ADSM, it begins like your concept of a
1441 base job. After that it is in the "incremental" mode. You can
1442 configure the number of "generations" of files to be retained, plus a
1443 retention date after which even old generations are purged. The
1444 database tracks the contents of media and projects the percentage of
1445 each volume that is valid. When the valid content of a volume drops
1446 below a configured percentage, the valid data are migrated to another
1447 volume and the old volume is marked as empty. Note, this requires
1448 ADSM to have an idea of the contents of a client, i.e. marking the
1449 database when an existing file was deleted, but this would solve your
1450 issue of restoring a client without restoring deleted files.
1452 This is pretty far from what bacula now does, but if you are going to
1453 rip things up for Base jobs,.....
1454 Also, the benefits of this are huge for very large shops, especially
1455 with media robots, but are a pain for shops with manual media
1459 > Base jobs sound pretty useful, but I'm not dying for them.
1461 Nobody is dying for them, but when you see what it does, you will die
1464 3. Restoring deleted files: Since I think my comments in (2) above
1465 have low probability of implementation, I'll also suggest that you
1466 could approach the issue of deleted files by a mechanism of having the
1467 fd report to the dir, a list of all files on the client for every
1468 backup job. The dir could note in the database entry for each file
1469 the date that the file was seen. Then if a restore as of date X takes
1470 place, only files that exist from before X until after X would be
1471 restored. Probably the major cost here is the extra date container in
1472 each row of the files table.
1474 Thanks for "listening". I hope some of this helps. If you want to
1475 contact me, please send me an email - I read some but not all of the
1476 mailing list traffic and might miss a reply there.
1478 Please accept my compliments for bacula. It is doing a great job for
1479 me!! I sympathize with you in the need to wrestle with excelence in
1480 execution vs. excelence in feature inclusion.
1485 ==============================
1488 - Design at hierarchial storage for Bacula. Migration and Clone.
1489 - Implement FSM (File System Modules).
1490 - Audit M_ error codes to ensure they are correct and consistent.
1491 - Add variable break characters to lex analyzer.
1492 Either a bit mask or a string of chars so that
1493 the caller can change the break characters.
1494 - Make a single T_BREAK to replace T_COMMA, etc.
1495 - Ensure that File daemon and Storage daemon can
1496 continue a save if the Director goes down (this
1497 is NOT currently the case). Must detect socket error,
1498 buffer messages for later.
1499 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1500 - Add ability to backup to two Storage devices (two SD sessions) at
1501 the same time -- e.g. onsite, offsite.
1502 - Add the ability to consolidate old backup sets (basically do a restore
1503 to tape and appropriately update the catalog). Compress Volume sets.
1504 Might need to spool via file is only one drive is available.
1505 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1506 someway to do so with every volume that has less than x% valid
1510 Migration: Move a backup from one Volume to another
1511 Clone: Copy a backup -- two Volumes
1514 ======================================================
1516 It is somewhat like a Full save becomes an incremental since
1517 the Base job (or jobs) plus other non-base files.
1519 - A Base backup is same as Full backup, just different type.
1520 - New BaseFiles table that contains:
1522 BaseJobId - Base JobId referenced for this FileId (needed ???)
1523 JobId - JobId currently running
1524 FileId - File not backed up, exists in Base Job
1525 FileIndex - FileIndex from Base Job.
1526 i.e. for each base file that exists but is not saved because
1527 it has not changed, the File daemon sends the JobId, BaseId,
1528 FileId, FileIndex back to the Director who creates the DB entry.
1529 - To initiate a Base save, the Director sends the FD
1530 the FileId, and full filename for each file in the Base.
1531 - When the FD finds a Base file, he requests the Director to
1532 send him the full File entry (stat packet plus MD5), or
1533 conversely, the FD sends it to the Director and the Director
1534 says yes or no. This can be quite rapid if the FileId is kept
1535 by the FD for each Base Filename.
1536 - It is probably better to have the comparison done by the FD
1537 despite the fact that the File entry must be sent across the
1539 - An alternative would be to send the FD the whole File entry
1540 from the start. The disadvantage is that it requires a lot of
1541 space. The advantage is that it requires less communications
1543 - The Job record must be updated to indicate that one or more
1545 - At end of Job, FD returns:
1546 1. Count of base files/bytes not written to tape (i.e. matches)
1547 2. Count of base file that were saved i.e. had changed.
1548 - No tape record would be written for a Base file that matches, in the
1549 same way that no tape record is written for Incremental jobs where
1550 the file is not saved because it is unchanged.
1551 - On a restore, all the Base file records must explicitly be
1552 found from the BaseFile tape. I.e. for each Full save that is marked
1553 to have one or more Base Jobs, search the BaseFile for all occurrences
1555 - An optimization might be to make the BaseFile have:
1561 This would avoid the need to explicitly fetch each File record for
1562 the Base job. The Base Job record will be fetched to get the
1563 VolSessionId and VolSessionTime.
1564 =========================================================
1567 ==========================================================
1569 For each Incremental job that is run, there may be files that
1570 were found but not saved because they were locked (this applies
1571 only to Windows). Such a system could send back to the Director
1572 a list of Unsaved files.
1574 - New UnSavedFiles table that contains:
1578 - Then in the next Incremental job, the list of Unsaved Files will be
1579 feed to the FD, who will ensure that they are explicitly chosen even
1580 if standard date/time check would not have selected them.

1625 There needs to be a table of drive # to devices somewhere - If there are
1626 multiple changers or drives there may not be a 1:1 correspondance between
1627 changer drive number and system device name - and depending on the way the
1628 drives are hooked up to scsi busses, they may not be linearly numbered
1629 from an offset point either.something like
1631 Autochanger drives = 2
1632 Autochanger drive 0 = /dev/nst1
1633 Autochanger drive 1 = /dev/nst2
1634 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1635 times, not just for multidrive changers. For a 1 drive changer, that's
1641 MTX's manpage (1.2.15):
1642 unload [<slotnum>] [ <drivenum> ]
1643 Unloads media from drive <drivenum> into slot
1644 <slotnum>. If <drivenum> is omitted, defaults to
1645 drive 0 (as do all commands). If <slotnum> is
1646 omitted, defaults to the slot that the drive was
1647 loaded from. Note that there's currently no way
1648 to say 'unload drive 1's media to the slot it
1649 came from', other than to explicitly use that
1650 slot number as the destination.AB

1688 Handling removable disks
1690 From: Karl Cunningham <karlc@keckec.com>
1692 My backups are only to hard disk these days, in removable bays. This is my
1693 idea of how a backup to hard disk would work more smoothly. Some of these
1694 things Bacula does already, but I mention them for completeness. If others
1695 have better ways to do this, I'd like to hear about it.
1697 1. Accommodate several disks, rotated similar to how tapes are. Identified
1698 by partition volume ID or perhaps by the name of a subdirectory.
1699 2. Abort & notify the admin if the wrong disk is in the bay.
1700 3. Write backups to different subdirectories for each machine to be backed
1702 4. Volumes (files) get created as needed in the proper subdirectory, one
1704 5. When a disk is recycled, remove or zero all old backup files. This is
1705 important as the disk being recycled may be close to full. This may be
1706 better done manually since the backup files for many machines may be
1707 scattered in many subdirectories.
1712 - Why the heck doesn't bacula drop root priviledges before connecting to
1714 - Look at using posix_fadvise(2) for backups -- see bug #751.
1715 Possibly add the code at findlib/bfile.c:795
1716 /* TCP socket options */
1717 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
