16 if the system "sees" a long path once, it seems to forget it's
17 working drive (e.g. c:\), which will lead to a problem during
18 the next job (create bootstrap file will fail). Here is the

129 - It appears to me that you have run into some sort of race
130 condition where two threads want to use the same Volume and they
131 were both given access. Normally that is no problem. However,
132 one thread wanted the particular Volume in drive 0, but it was
133 loaded into drive 1 so it decided to unload it from drive 1 and
134 then loaded it into drive 0, while the second thread went on
135 thinking that the Volume could be used in drive 1 not realizing
136 that in between time, it was loaded in drive 0.
137 I'll look at the code to see if there is some way we can avoid
138 this kind of problem. Probably the best solution is to make the
139 first thread simply start using the Volume in drive 1 rather than
140 transferring it to drive 0.
141 - Fix re-read of last block to check if job has actually written
142 a block, and check if block was written by a different job
143 (i.e. multiple simultaneous jobs writing).
144 - Figure out how to configure query.sql. Suggestion to use m4:
145 == changequote.m4 ===
146 changequote(`[',`]')dnl
147 ==== query.sql.in ===

150 Pool.Name AS PoolName,
155 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
157 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
161 ON Media.PoolId=Pool.PoolId
162 WHERE Media.LastWritten>0
166 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
168 The problem is that it requires m4, which is not present on all machines
170 - Given all the problems with FIFOs, I think the solution is to do something a
171 little different, though I will look at the code and see if there is not some
172 simple solution (i.e. some bug that was introduced). What might be a better
173 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
174 write data to a program rather than the FIFO. For example, suppose you
179 Then, I could imagine if you backup and restore this file with a direct
180 reference as is currently done for fifos, instead, during backup Bacula will
183 /home/kern/my-fifo.backup
185 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
188 /home/kern/my-fifo.restore
190 and send the data backed up to stdout. These programs can either be an
191 executable or a shell script and they need only read/write to stdin/stdout.
193 I think this would give a lot of flexibility to the user without making any
194 significant changes to Bacula.
199 select FilenameId from Filename where Name='';

211 === Migration from David ===
212 What I'd like to see:
215 Name = "<poolname>-migrate"
219 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
220 Client | PoolResidence | Volume | JobName | SQLquery
221 Migration Selection Pattern = "regexp"
222 Next Pool = <override>
225 There should be no need for a Level (migration is always Full, since you
226 don't calculate differential/incremental differences for migration),
227 Storage should be determined by the volume types in the pool, and Client
228 is really a selection issue. Migration should always occur to the
229 NextPool defined in the pool definition. If no nextpool is defined, the
230 job should end with a reason of "no place to go". If Next Pool statement
231 is present, we override the check in the pool definition and use the
234 Here's how I'd define Migration Selection Types:
237 Client -- Migrate data from selected client only. Migration Selection
238 Pattern regexp provides pattern to select client names, eg ^FS00* makes
239 all client names starting with FS00 eligible for migration.
241 Jobname -- Migration all jobs matching name. Migration Selection Pattern
242 regexp provides pattern to select jobnames existing in pool.
244 Volume -- Migrate all data on specified volumes. Migration Selection
245 Pattern regexp provides selection criteria for volumes to be migrated.
246 Volumes must exist in pool to be eligible for migration.
250 LowestUtil -- Identify the volume in the pool with the least data on it
251 and empty it. No Migration Selection Pattern required.
253 OldestVol -- Identify the LRU volume with data written, and empty it. No
254 Migration Selection Pattern required.
256 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
257 (starting with most full volumes) until pool occupancy drops below
258 <lowmig>. Pool highmig and lowmig values are in pool definition, no
259 Migration Selection Pattern required.
263 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
264 Migration Selection Pattern contains SQL query to execute; should return
265 a list of 1 or more jobuids to migrate.
267 PoolResidence -- Migrate data sitting in pool for longer than
268 PoolResidence value in pool definition. Migration Selection Pattern
269 optional; if specified, override value in pool definition (value in

447 1. When jobs are running and bacula for some reason crashes or if I do a
448 restart it remembers and jobs it was running before it crashed or restarted
449 as of now I loose all jobs if I restart it.
451 2. When spooling and in the midway if client is disconnected for instance a
452 laptop bacula completely discard the spool. It will be nice if it can write
453 that spool to tape so there will be some backups for that client if not all.
455 3. We have around 150 clients machines it will be nice to have a option to
456 upgrade all the client machines bacula version automatically.
458 4. Atleast one connection should be reserved for the bconsole so at heavy load
459 I should connect to the director via bconsole which at sometimes I can't
461 5. Another most important feature that is missing, say at 10am I manually
462 started backup of client abc and it was a full backup since client abc has
463 no backup history and at 10.30am bacula again automatically started backup of
464 client abc as that was in the schedule. So now we have 2 multiple Full
465 backups of the same client and if we again try to start a full backup of
466 client backup abc bacula won't complain. That should be fixed.
468 - Fix bpipe.c so that it does not modify results pointer.
469 ***FIXME*** calling sequence should be changed.
470 - For Windows disaster recovery see http://unattended.sf.net/
471 - regardless of the retention period, Bacula will not prune the
472 last Full, Diff, or Inc File data until a month after the
473 retention period for the last Full backup that was done.
474 - update volume=xxx --- add status=Full
475 - Remove old spool files on startup.
476 - Exclude SD spool/working directory.
477 - Refuse to prune last valid Full backup. Same goes for Catalog.
479 - Make a callback when Rerun failed levels is called.
480 - Give Python program access to Scheduled jobs.
481 - Add setting Volume State via Python.
482 - Python script to save with Python, not save, save with Bacula.
483 - Python script to do backup.
485 - Change the Priority, Client, Storage, JobStatus (error)
486 at the start of a job.
487 - Why is SpoolDirectory = /home/bacula/spool; not reported
488 as an error when writing a DVD?
489 - Make bootstrap file handle multiple MediaTypes (SD)
490 - Remove all old Device resource code in Dir and code to pass it
491 back in SD -- better, rework it to pass back device statistics.
492 - Check locking of resources -- be sure to lock devices where previously
493 resources were locked.
494 - The last part is left in the spool dir.
497 - In restore don't compare byte count on a raw device -- directory
498 entry does not contain bytes.
502 MA = (last_MA * 3 + rate) / 4
503 rate = (bytes - last_bytes) / (runtime - last_runtime)
504 - Max Vols limit in Pool off by one?
505 - Implement Files/Bytes,... stats for restore job.
506 - Implement Total Bytes Written, ... for restore job.
507 - Despool attributes simultaneously with data in a separate
508 thread, rejoined at end of data spooling.
509 - 7. Implement new Console commands to allow offlining/reserving drives,
510 and possibly manipulating the autochanger (much asked for).
511 - Add start/end date editing in messages (%t %T, %e?) ...
512 - Add ClientDefs similar to JobDefs.
513 - Print more info when bextract -p accepts a bad block.
514 - Fix FD JobType to be set before RunBeforeJob in FD.
515 - Look at adding full Volume and Pool information to a Volume
516 label so that bscan can get *all* the info.
517 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
518 and there is only one volume in the pool, refuse to do it -- otherwise
519 he fills the Volume, then immediately starts reusing it.
520 - Implement copies and stripes.
521 - Add history file to console.
522 - Each file on tape creates a JobMedia record. Peter has 4 million
523 files spread over 10000 tape files and four tapes. A restore takes
524 16 hours to build the restore list.
525 - Add and option to check if the file size changed during backup.
526 - Make sure SD deletes spool files on error exit.
527 - Delete old spool files when SD starts.
528 - When labeling tapes, if you enter 000026, Bacula uses
529 the tape index rather than the Volume name 000026.
530 - Add offline tape command to Bacula console.
532 Enter MediaId or Volume name: 32
533 Enter new Volume name: DLT-20Dec04

544 - Bug: if a job is manually scheduled to run later, it does not appear
545 in any status report and cannot be cancelled.
547 ==== Keeping track of deleted/new files ====
548 - To mark files as deleted, run essentially a Verify to disk, and
549 when a file is found missing (MarkId != JobId), then create
550 a new File record with FileIndex == -1. This could be done
551 by the FD at the same time as the backup.
553 My "trick" for keeping track of deletions is the following.
554 Assuming the user turns on this option, after all the files
555 have been backed up, but before the job has terminated, the
556 FD will make a pass through all the files and send their
557 names to the DIR (*exactly* the same as what a Verify job
558 currently does). This will probably be done at the same
559 time the files are being sent to the SD avoiding a second
560 pass. The DIR will then compare that to what is stored in
561 the catalog. Any files in the catalog but not in what the
562 FD sent will receive a catalog File entry that indicates
563 that at that point in time the file was deleted. This
564 either transmitted to the FD or simultaneously computed in
565 the FD, so that the FD can put a record on the tape that
566 indicates that the file has been deleted at this point.
567 A delete file entry could potentially be one with a FileIndex
568 of 0 or perhaps -1 (need to check if FileIndex is used for
569 some other thing as many of the Bacula fields are "overloaded"
572 During a restore, any file initially picked up by some
573 backup (Full, ...) then subsequently having a File entry
574 marked "delete" will be removed from the tree, so will not
575 be restored. If a file with the same name is later OK it
576 will be inserted in the tree -- this already happens. All
577 will be consistent except for possible changes during the
580 Since I'm on the subject, some of you may be wondering what
581 the utility of the in memory tree is if you are going to
582 restore everything (at least it comes up from time to time
583 on the list). Well, it is still *very* useful because it
584 allows only the last item found for a particular filename
585 (full path) to be entered into the tree, and thus if a file
586 is backed up 10 times, only the last copy will be restored.
587 I recently (last Friday) restored a complete directory, and
588 the Full and all the Differential and Incremental backups
589 spanned 3 Volumes. The first Volume was not even mounted
590 because all the files had been updated and hence backed up
591 since the Full backup was made. In this case, the tree
592 saved me a *lot* of time.
594 Make sure this information is stored on the tape too so
595 that it can be restored directly from the tape.
597 All the code (with the exception of formally generating and
598 saving the delete file entries) already exists in the Verify
599 Catalog command. It explicitly recognizes added/deleted files since
600 the last InitCatalog. It is more or less a "simple" matter of
601 taking that code and adapting it slightly to work for backups.
603 Comments from Martin Simmons (I think they are all covered):
604 Ok, that should cover the basics. There are few issues though:
606 - Restore will depend on the catalog. I think it is better to include the
607 extra data in the backup as well, so it can be seen by bscan and bextract.
609 - I'm not sure if it will preserve multiple hard links to the same inode. Or
610 maybe adding or removing links will cause the data to be dumped again?
612 - I'm not sure if it will handle renamed directories. Possibly it will work
613 by dumping the whole tree under a renamed directory?
615 - It remains to be seen how the backup performance of the DIR's will be
616 affected when comparing the catalog for a large filesystem.
620 How about introducing a Type = MgmtPolicy job type? That job type would
621 be responsible for scanning the Bacula environment looking for specific
622 conditions, and submitting the appropriate jobs for implementing said
626 Name = "Migration-Policy"
628 Policy Selection Job Type = Migrate
629 Scope = "<keyword> <operator> <regexp>"
630 Threshold = "<keyword> <operator> <regexp>"
631 Job Template = <template-name>
634 Where <keyword> is any legal job keyword, <operator> is a comparison
635 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
636 appropriate regexp. I could see an argument for Scope and Threshold
637 being SQL queries if we want to support full flexibility. The
638 Migration-Policy job would then get scheduled as frequently as a site
639 felt necessary (suggested default: every 15 minutes).
644 Name = "Migration-Policy"
646 Policy Selection Job Type = Migration
648 Threshold = "Migration Selection Type = LowestUtil"
649 Job Template = "MigrationTemplate"
652 would select all pools for examination and generate a job based on
653 MigrationTemplate to automatically select the volume with the lowest
654 usage and migrate it's contents to the nextpool defined for that pool.
656 This policy abstraction would be really handy for adjusting the behavior
657 of Bacula according to site-selectable criteria (one thing that pops
658 into mind is Amanda's ability to automatically adjust backup levels
659 depending on various criteria).
665 - Add Pool/Storage override regression test.
666 - Add delete JobId to regression.
667 - Add a regression test for dbcheck.
668 - New test to add bscan to four-concurrent-jobs regression,
669 i.e. after the four-concurrent jobs zap the
670 database as is done in the bscan-test, then use bscan to
671 restore the database, do a restore and compare with the
673 - Add restore of specific JobId to regression (item 3
674 on the restore prompt)
675 - Add IPv6 to regression
676 - Add database test to regression. Test each function like delete,
679 - AntiVir can slow down backups on Win32 systems.
680 - Win32 systems with FAT32 can be much slower than NTFS for
681 more than 1000 files per directory.
685 - A HOLD command to stop all jobs from starting.
686 - A PAUSE command to pause all running jobs ==> release the
688 - Media Type = LTO,LTO-2,LTO-3
689 Media Type Read = LTO,LTO2,LTO3
690 Media Type Write = LTO2, LTO3
692 === From Carsten Menke <bootsy52@gmx.net>
694 Following is a list of what I think in the situations where I'm faced with,
695 could be a usefull enhancement to bacula, which I'm certain other users will
696 benefit from as well.
698 1. NextJob/NextJobs Directive within a Job Resource in the form of
699 NextJobs = job1,job2.
702 I currently solved the problem with running multiple jobs each after each
703 by setting the Max Wait Time for a job to 8 hours, and give
704 the jobs different Priorities. However, there scenarios where
705 1 Job is directly depending on another job, so if the former job fails,
706 the job after it needn't to be run
707 while maybe other jobs should run despite of that
710 A Backup Job and a Verify job, if the backup job fails there is no need to run
711 the verify job, as the backup job already failed. However, one may like
712 to backup the Catalog to disk despite of that the main backup job failed.
715 I see that this is related to the Event Handlers which are on the ToDo
716 list, also it is maybe a good idea to check for the return value and
717 execute different actions based on the return value
720 3. offline capability to bconsole
723 Currently I use a script which I execute within the last Job via the
724 RunAfterJob Directive, to release and eject the tape.
725 So I have to call bconsole "release=Storage-Name" and afterwards
726 mt -f /dev/nst0 eject to get the tape out.
728 If I have multiple Storage Devices, than these may not be /dev/nst0 and
729 I have to modify the script or call it with parameters etc.
730 This would actually not be needed, as everything is already defined
731 in bacula-sd.conf and if I can invoke bconsole with the
732 storage name via $1 in the script than I'm done and information is
735 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
739 For the reason mentioned in 3. to have the ability to call a
740 script with /scripts/foobar %s and in the script use $1
741 to pass the Storage Name to bconsole
743 5. Setting Volume State within a Job Resource
746 Instead of using "Maximum Volume Jobs" in the Pool Resource,
747 I would have the possibilty to define
748 in a Job Resource that after this certain job is run, the Volume State
749 should be set to "Volume State = Used", this give more flexibility (IMHO).
751 6. Localization of Bacula Messages
754 Unfortunatley many,many people I work with don't speak english very well.
755 So if at least the Reporting messages would be localized then they
756 would understand that they have to change the tape,etc. etc.
758 I volunteer to do the german translations, and if I can convince my wife also
759 french and Morre (western african language).
761 7. OK, this is evil, probably bound to security risks and maybe not possible
762 due to the design of bacula.
764 Implementation of Backtics ( `command` ) for shell comand execution to
765 the "Label Format" Directive.
769 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
770 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
771 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
772 the localized name for the day of the week appended to the
773 format string. Then I have the tape labeled automatically with weekday
774 name in the correct language.
776 - Yes, that is surely the case. I probably should turn those into Warning
777 errors. In addition, you just made me think that it might not be bad to
778 add an option to check the file size after backing up the file and
779 report if it changes. This would be done as an option because it would
782 Kern, good idea. If you do do that, mention in the output: file
783 shrunk, or file expanded, just to make it obvious to the user
784 (without having to the refer to file size), just how the file size
787 Would this option be for all file, or just one file? Or a fileset?
788 - Make output from status use html table tags for nicely
789 presenting in a browser.
790 - Can one write tapes faster with 8192 byte block sizes?
791 - Document security problems with the same password for everyone in
792 rpm and Win32 releases.
793 - Browse generations of files.
794 - I've seen an error when my catalog's File table fills up. I
795 then have to recreate the File table with a larger maximum row
796 size. Relevant information is at
797 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
798 "Installing and Configuring MySQL" chapter should talk a bit
799 about this potential problem, and recommend a solution.
800 - For Solaris must use POSIX awk.
801 - Want speed of writing to tape while despooling.
802 - Supported autochanger:
810 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
811 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
812 - Add regex from http://www.pcre.org to Bacula for Win32.
813 - Use only shell tools no make in CDROM package.
814 - Include within include does it work?
815 - Implement a Pool of type Cleaning?
816 - Implement VolReadTime and VolWriteTime in SD
817 - Modify Backing up Your Database to include a bootstrap file.
818 - Think about making certain database errors fatal.
819 - Look at correcting the time jump in the scheduler for daylight
820 savings time changes.
821 - Add a "real" timer to network connections.
822 - Promote to Full = Time period
823 - Check dates entered by user for correctness (month/day/... ranges)
824 - Compress restore Volume listing by date and first file.
825 - Look at patches/bacula_db.b2z postgresql that loops during restore.
827 - Perhaps add read/write programs and/or plugins to FileSets.
828 - How to handle backing up portables ...
829 - Add some sort of guaranteed Interval for upgrading jobs.
830 - Can we write the state file after every job terminates? On Win32
831 the system crashes and the state file is not updated.
834 Documentation to do: (any release a little bit at a time)
835 - Doc to do unmount before removing magazine.
836 - Alternative to static linking "ldd prog" save all binaries listed,
837 restore them and point LD_LIBRARY_PATH to them.
838 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
839 - Document query file format.
840 - Add more documentation for bsr files.
841 - Document problems with Verify and pruning.
842 - Document how to use multiple databases.
843 - VXA drives have a "cleaning required"
844 indicator, but Exabyte recommends preventive cleaning after every 75
847 In this context, it should be noted that Exabyte has a command-line
848 vxatool utility available for free download. (The current version is
849 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
850 test the drive, unload tapes, change drive settings, flash new firmware,
852 Of particular interest in this context is that vxatool <device> -i will
853 report, among other details, the time since last cleaning in tape motion
854 minutes. This information can be retrieved (and settings changed, for
855 that matter) through the generic-SCSI device even when Bacula has the
856 regular tape device locked. (Needless to say, I don't recommend
857 changing tape settings while a job is running.)
858 - Lookup HP cleaning recommendations.
859 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
860 - Document doing table repair
863 ===================================
864 - Add macro expansions in JobDefs.
865 Run Before Job = "SomeFile %{Level} %{Client}"
866 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
867 - Use non-blocking network I/O but if no data is available, use
869 - Use gather write() for network I/O.
870 - Autorestart on crash.
871 - Add bandwidth limiting.
872 - Add acks every once and a while from the SD to keep
873 the line from timing out.
874 - When an error in input occurs and conio beeps, you can back
875 up through the prompt.
876 - Detect fixed tape block mode during positioning by looking at
877 block numbers in btape "test". Possibly adjust in Bacula.
878 - Fix list volumes to output volume retention in some other
879 units, perhaps via a directive.
880 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
881 with multiple priorities.
882 - If you use restore replace=never, the directory attributes for
883 non-existent directories will not be restored properly.
885 - see lzma401.zip in others directory for new compression
887 - Allow the user to select JobType for manual pruning/purging.
888 - bscan does not put first of two volumes back with all info in
890 - Implement the FreeBSD nodump flag in chflags.
891 - Figure out how to make named console messages go only to that
892 console and to the non-restricted console (new console class?).
893 - Make restricted console prompt for password if *ask* is set or
894 perhaps if password is undefined.
895 - Implement "from ISO-date/time every x hours/days/weeks/months" in
898 ==== from Marc Schoechlin
899 - the help-command should be more verbose
900 (it should explain the paramters of the different
902 -> its time-comsuming to consult the manual anytime
903 you need a special parameter
904 -> maybe its more easy to maintain this, if the
905 descriptions of that commands are outsourced to
907 - the cd-command should allow complete paths
908 i.e. cd /foo/bar/foo/bar
909 -> if a customer mails me the path to a certain file,
910 its faster to enter the specified directory
911 - if the password is not configured in bconsole.conf
912 you should be asked for it.
913 -> sometimes you like to do restore on a customer-machine
914 which shouldnt know the password for bacula.
915 -> adding the password to the file favours admins
916 to forget to remove the password after usage
918 the protection of that file is less important
919 - long-listed-output of commands should be scrollable
920 like the unix more/less-command does
921 -> if someone runs 200 and more machines, the lists could
922 be a little long and complex
923 - command-output should be shown column by column
924 to reduce scrolling and to increase clarity
926 - lsmark should list the selected files with full
928 - wildcards for selecting and file and directories would be nice
929 - any actions should be interuptable with STRG+C
930 - command-expansion would be pretty cool
932 - When the replace Never option is set, new directory permissions
933 are not restored. See bug 213. To fix this requires creating a
934 list of newly restored directories so that those directory
935 permissions *can* be restored.
936 - Add prune all command
937 - Document fact that purge can destroy a part of a restore by purging
938 one volume while others remain valid -- perhaps mark Jobs.
939 - Add multiple-media-types.txt
940 - look at mxt-changer.html
941 - Make ? do a help command (no return needed).
942 - Implement restore directory.
943 - Document streams and how to implement them.
944 - Try not to re-backup a file if a new hard link is added.
945 - Add feature to backup hard links only, but not the data.
946 - Fix stream handling to be simpler.
947 - Add Priority and Bootstrap to Run a Job.
948 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
950 - Remove View FileSet button from Run a Job dialog.
951 - Handle prompt for restore job at end of Restore command.
952 - Add display of total selected files to Restore window.
953 - Add tree pane to left of window.
954 - Add progress meter.
955 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
956 - Add message to user to check for fixed block size when the forward
957 space test fails in btape.
958 - When unmarking a directory check if all files below are unmarked and
959 then remove the + flag -- in the restore tree.
960 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
961 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
962 - Revisit the question of multiple Volumes (disk) on a single device.
963 - Add a block copy option to bcopy.
964 - Finish work on Gnome restore GUI.
965 - Fix "llist jobid=xx" where no fileset or client exists.
966 - For each job type (Admin, Restore, ...) require only the really necessary
967 fields.- Pass Director resource name as an option to the Console.
968 - Add a "batch" mode to the Console (no unsolicited queries, ...).
969 - Add a .list all files in the restore tree (probably also a list all files)
970 Do both a long and short form.
971 - Allow browsing the catalog to see all versions of a file (with
972 stat data on each file).
973 - Restore attributes of directory if replace=never set but directory
975 - Use SHA1 on authentication if possible.
976 - See comtest-xxx.zip for Windows code to talk to USB.
977 - Add John's appended files:
978 Appended = { /files/server/logs/http/*log }
979 and such files would be treated as follows.On a FULL backup, they would
980 be backed up like any other file.On an INCREMENTAL backup, where a
981 previous INCREMENTAL or FULL was already in thecatalogue and the length
982 of the file wasgreater than the length of the last backup, only thedata
983 added since the last backup will be dumped.On an INCREMENTAL backup, if
984 the length of the file is less than thelength of the file with the same
985 name last backed up, the completefile is dumped.On Windows systems, with
986 creation date of files, we can be evensmarter about this and not count
987 entirely upon the length.On a restore, the full and all incrementals
988 since it will beapplied in sequence to restore the file.
989 - Check new HAVE_WIN32 open bits.
990 - Check if the tape has moved before writing.
991 - Handling removable disks -- see below:
992 - Keep track of tape use time, and report when cleaning is necessary.
993 - Add FromClient and ToClient keywords on restore command (or
994 BackupClient RestoreClient).
995 - Implement a JobSet, which groups any number of jobs. If the
996 JobSet is started, all the jobs are started together.
997 Allow Pool, Level, and Schedule overrides.
998 - Enhance cancel to timeout BSOCK packets after a specific delay.
999 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1000 ua_status.!!! Thanks to Alan Brown for this tip.
1001 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1002 correctly for multiple simultaneous jobs.
1003 - Correct code so that FileSet MD5 is calculated for < and | filename
1005 - Implement the Media record flag that indicates that the Volume does disk
1007 - Implement VolAddr, which is used when Volume is addressed like a disk,
1008 and form it from VolFile and VolBlock.
1009 - Make multiple restore jobs for multiple media types specifying
1010 the proper storage type.
1011 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1012 pointer (rec) to try_repositioning().
1013 - Look at extracting Win data from BackupRead.
1014 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1015 which would take precidence over the Catalog "JobRetention".
1016 - Implement Label Format in Add and Label console commands.
1017 - Possibly up network buffers to 65K. Put on variable.
1018 - Put email tape request delays on one or more variables. User wants
1019 to cancel the job after a certain time interval. Maximum Mount Wait?
1020 - Job, Client, Device, Pool, or Volume?
1021 Is it possible to make this a directive which is *optional* in multiple
1022 resources, like Level? If so, I think I'd make it an optional directive
1023 in Job, Client, and Pool, with precedence such that Job overrides Client
1024 which in turn overrides Pool.
1026 - New Storage specifications:
1027 - Want to write to multiple storage devices simultaneously
1028 - Want to write to multiple storage devices sequentially (in one job)
1029 - Want to read/write simultaneously
1030 - Key is MediaType -- it must match
1032 Passed to SD as a sort of BSR record called Storage Specification
1036 MediaType -> Next MediaType
1038 Device -> Next Device
1040 Allow multiple Storage specifications
1048 Allow Multiple Pool specifications (note, Pool currently
1050 Allow Multiple MediaType specifications in Dir conf
1051 Allow Multiple Device specifications in Dir conf
1052 Perhaps keep this in a single SSR
1053 Tie a Volume to a specific device by using a MediaType that
1054 is contained in only one device.
1055 In SD allow Device to have Multiple MediaTypes
1057 - Ideas from Jerry Scharf:
1058 First let's point out some big pluses that bacula has for this
1060 more importantly it's active. Thank you so much for that
1061 even more important, it's not flaky
1062 it has an open access catalog, opening many possibilities
1063 it's pushing toward heterogeneous systems capability
1065 Macintosh file client
1066 macs are an interesting niche, but I fear a server is a rathole
1067 working bare iron recovery for windows
1068 the option for inc/diff backups not reset on fileset revision
1069 a) use both change and inode update time against base time
1070 b) do the full catalog check (expensive but accurate)
1071 sizing guide (how much system is needed to back up N systems/files)
1072 consultants on using bacula in building a disaster recovery system
1073 an integration guide
1074 or how to get at fancy things that one could do with bacula
1075 logwatch code for bacula logs (or similar)
1076 linux distro inclusion of bacula (brings good and bad, but necessary)
1077 win2k/XP server capability (icky but you asked)
1078 support for Oracle database ??
1080 - Look at adding SQL server and Exchange support for Windows.
1081 - Make dev->file and dev->block_num signed integers so that -1 can
1082 be an invalid value which happens with BSR.
1083 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1084 is needed to properly specify ranges.
1085 - Add progress of files/bytes to SD and FD.
1086 - Print warning message if FileId > 4 billion
1087 - do a "messages" before the first prompt in Console
1088 - Client does not show busy during Estimate command.
1089 - Implement Console mtx commands.
1090 - Implement a Mount Command and an Unmount Command where
1091 the users could specify a system command to be performed
1092 to do the mount, after which Bacula could attempt to
1093 read the device. This is for Removeable media such as a CDROM.
1094 - Most likely, this mount command would be invoked explicitly
1095 by the user using the current Console "mount" and "unmount"
1096 commands -- the Storage Daemon would do the right thing
1097 depending on the exact nature of the device.
1098 - As with tape drives, when Bacula wanted a new removable
1099 disk mounted, it would unmount the old one, and send a message
1100 to the user, who would then use "mount" as described above
1101 once he had actually inserted the disk.
1102 - Implement dump/print label to UA
1103 - Spool to disk only when the tape is full, then when a tape is hung move
1105 - bextract is sending everything to the log file ****FIXME****
1106 - Allow multiple Storage specifications (or multiple names on
1107 a single Storage specification) in the Job record. Thus a job
1108 can be backed up to a number of storage devices.
1109 - Implement some way for the File daemon to contact the Director
1110 to start a job or pass its DHCP obtained IP number.
1111 - Implement a query tape prompt/replace feature for a console
1112 - Copy console @ code to gnome2-console
1113 - Make tree walk routines like cd, ls, ... more user friendly
1114 by handling spaces better.
1115 - Make sure that Bacula rechecks the tape after the 20 min wait.
1116 - Set IO_NOWAIT on Bacula TCP/IP packets.
1117 - Try doing a raw partition backup and restore by mounting a
1119 - From Lars Kellers:
1120 Yes, it would allow to highly automatic the request for new tapes. If a
1121 tape is empty, bacula reads the barcodes (native or simulated), and if
1122 an unused tape is found, it runs the label command with all the
1123 necessary parameters.
1125 By the way can bacula automatically "move" an empty/purged volume say
1126 in the "short" pool to the "long" pool if this pool runs out of volume
1128 - What to do about "list files job=xxx".
1129 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1130 file descriptor leak in Bacula.
1131 - Implement WrapCounters in Counters.
1132 - Add heartbeat from FD to SD if hb interval expires.
1133 - Can we dynamically change FileSets?
1134 - If pool specified to label command and Label Format is specified,
1135 automatically generate the Volume name.
1136 - Why can't SQL do the filename sort for restore?
1137 - Add ExhautiveRestoreSearch
1138 - Look at the possibility of loading only the necessary
1139 data into the restore tree (i.e. do it one directory at a
1140 time as the user walks through the tree).
1141 - Possibly use the hash code if the user selects all for a restore command.
1142 - Fix "restore all" to bypass building the tree.
1143 - Prohibit backing up archive device (findlib/find_one.c:128)
1144 - Implement Release Device in the Job resource to unmount a drive.
1145 - Implement Acquire Device in the Job resource to mount a drive,
1146 be sure this works with admin jobs so that the user can get
1147 prompted to insert the correct tape. Possibly some way to say to
1148 run the job but don't save the files.
1149 - Make things like list where a file is saved case independent for
1151 - Use autochanger to handle multiple devices.
1152 - Implement a Recycle command
1153 - Start working on Base jobs.
1154 - Implement UnsavedFiles DB record.
1155 - From Phil Stracchino:
1156 It would probably be a per-client option, and would be called
1157 something like, say, "Automatically purge obsoleted jobs". What it
1158 would do is, when you successfully complete a Differential backup of a
1159 client, it would automatically purge all Incremental backups for that
1160 client that are rendered redundant by that Differential. Likewise,
1161 when a Full backup on a client completed, it would automatically purge
1162 all Differential and Incremental jobs obsoleted by that Full backup.
1163 This would let people minimize the number of tapes they're keeping on
1164 hand without having to master the art of retention times.
1165 - When doing a Backup send all attributes back to the Director, who
1166 would then figure out what files have been deleted.
1167 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1168 explicit permission to do so. It should also mark the tape in error
1169 if there is an error.
1170 - Cancel waiting for Client connect in SD if FD goes away.
1172 - Implement timeout in response() when it should come quickly.
1173 - Implement a Slot priority (loaded/not loaded).
1174 - Implement "vacation" Incremental only saves.
1175 - Implement create "FileSet"?
1176 - Add prefixlinks to where or not where absolute links to FD.
1177 - Issue message to mount a new tape before the rewind.
1178 - Simplified client job initiation for portables.
1179 - If SD cannot open a drive, make it periodically retry.
1180 - Add more of the config info to the tape label.
1182 - Refine SD waiting output:
1183 Device is being positioned
1184 > Device is being positioned for append
1185 > Device is being positioned to file x
1187 - Figure out some way to estimate output size and to avoid splitting
1188 a backup across two Volumes -- this could be useful for writing CDROMs
1189 where you really prefer not to have it split -- not serious.
1190 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1191 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1192 actual data on the Volume and compare it.
1193 - Implement Bacula plugins -- design API
1194 - Make bcopy read through bad tape records.
1195 - Program files (i.e. execute a program to read/write files).
1196 Pass read date of last backup, size of file last time.
1197 - Add Signature type to File DB record.
1198 - CD into subdirectory when open()ing files for backup to
1199 speed up things. Test with testfind().
1200 - Priority job to go to top of list.
1201 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1202 - Implement some way for the Console to dynamically create a job.
1203 - Solaris -I on tar for include list
1204 - Need a verbose mode in restore, perhaps to bsr.
1205 - bscan without -v is too quiet -- perhaps show jobs.
1206 - Add code to reject whole blocks if not wanted on restore.
1207 - Check if we can increase Bacula FD priorty in Win2000
1208 - Make sure the MaxVolFiles is fully implemented in SD
1209 - Check if both CatalogFiles and UseCatalog are set to SD.
1210 - Possibly add email to Watchdog if drive is unmounted too
1211 long and a job is waiting on the drive.
1212 - After unmount, if restore job started, ask to mount.
1213 - Add UA rc and history files.
1214 - put termcap (used by console) in ./configure and
1215 allow -with-termcap-dir.
1216 - Fix Autoprune for Volumes to respect need for full save.
1217 - Compare tape to Client files (attributes, or attributes and data)
1218 - Make all database Ids 64 bit.
1219 - Allow console commands to detach or run in background.
1220 - Add SD message variables to control operator wait time
1221 - Maximum Operator Wait
1222 - Minimum Message Interval
1223 - Maximum Message Interval
1224 - Send Operator message when cannot read tape label.
1225 - Verify level=Volume (scan only), level=Data (compare of data to file).
1226 Verify level=Catalog, level=InitCatalog
1228 - Add keyword search to show command in Console.
1229 - Events : tape has more than xxx bytes.
1230 - Complete code in Bacula Resources -- this will permit
1231 reading a new config file at any time.
1232 - Handle ctl-c in Console
1233 - Implement script driven addition of File daemon to config files.
1234 - Think about how to make Bacula work better with File (non-tape) archives.
1235 - Write Unix emulator for Windows.
1236 - Put memory utilization in Status output of each daemon
1237 if full status requested or if some level of debug on.
1238 - Make database type selectable by .conf files i.e. at runtime
1239 - Set flag for uname -a. Add to Volume label.
1240 - Restore files modified after date
1241 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1242 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1243 - Timout a job or terminate if link goes down, or reopen link and query.
1244 - Concept of precious tapes (cannot be reused).
1245 - Make bcopy copy with a single tape drive.
1246 - Permit changing ownership during restore.

1260 - Autolabel should be specified by DIR instead of SD.
1262 - Add media capacity
1263 - AutoScan (check checksum of tape)
1264 - Format command = "format /dev/nst0"
1268 - Seek resolution (usually corresponds to buffer size)
1269 - EODErrorCode=ENOSPC or code
1270 - Partial Read error code
1271 - Partial write error code
1272 - Nonformatted read error
1273 - Nonformatted write error
1274 - WriteProtected error
1278 - IgnoreCloseErrors=yes
1288 - FD sends unsaved file list to Director at end of job (see
1290 - File daemon should build list of files skipped, and then
1291 at end of save retry and report any errors.
1292 - Write a Storage daemon that uses pipes and
1293 standard Unix programs to write to the tape.
1295 - Need something that monitors the JCR queue and
1296 times out jobs by asking the deamons where they are.
1297 - Enhance Jmsg code to permit buffering and saving to disk.
1298 - device driver = "xxxx" for drives.
1299 - Verify from Volume
1300 - Ensure that /dev/null works
1301 - Need report class for messages. Perhaps
1302 report resource where report=group of messages
1303 - enhance scan_attrib and rename scan_jobtype, and
1304 fill in code for "since" option
1305 - Director needs a time after which the report status is sent
1306 anyway -- or better yet, a retry time for the job.
1307 - Don't reschedule a job if previous incarnation is still running.
1308 - Some way to automatically backup everything is needed????
1309 - Need a structure for pending actions:
1311 - termination status (part of buffered msgs?)
1313 Read, Write, Clean, Delete
1314 - Login to Bacula; Bacula users with different permissions:
1315 owner, group, user, quotas
1316 - Store info on each file system type (probably in the job header on tape.
1317 This could be the output of df; or perhaps some sort of /etc/mtab record.
1319 ========= ideas ===============
1320 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1321 To: <kern@sibbald.com>
1322 Subject: RE: [Bacula-users] future large programming jobs
1323 Date: Thu, 26 Feb 2004 11:34:54 -0600
1325 I noticed the subject thread and thought I would offer the following
1326 merely as sources of ideas, i.e. something to think about, not even as
1327 strong as a request. In my former life (before retiring) I often
1328 dealt with backups and storage management issues/products as a
1329 developer and as a consultant. I am currently migrating my personal
1330 network from amanda to bacula specifically because of the ability to
1331 cross media boundaries during storing backups.
1332 Are you familiar with the commercial product called ADSM (I think IBM
1333 now sells it under the Tivoli label)? It has a couple of interesting
1334 ideas that may apply to the following topics.
1336 1. Migration: Consider that when you need to restore a system, there
1337 may be pressure to hurry. If all the information for a single client
1338 can eventually end up on the same media (and in chronological order),
1339 the restore is facillitated by not having to search past information
1340 from other clients. ADSM has the concept of "client affinity" that
1341 may be associated with it's storage pools. It seems to me that this
1342 concept (as an optional feature) might fit in your architecture for
1345 ADSM also has the concept of defining one or more storage pools as
1346 "copy pools" (almost mirrors, but only in the sense of contents).
1347 These pools provide the ability to have duplicte data stored both
1348 onsite and offsite. The copy process can be scheduled to be handled
1349 by their storage manager during periods when there is no backup
1350 activity. Again, the migration process might be a place to consider
1351 implementing something like this.
1354 > It strikes me that it would be very nice to be able to do things
1356 > have the Job(s) backing up the machines run, and once they have all

1362 > mechanism described below would probably make it very easy.
1364 This is the goal. In the first step (before events), you simply
1366 the Migration to tape later.
1368 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1369 the database. Once a file (unique by path and metadata such as dates,
1370 size, ownership, etc.) is in a copy pool, no more copies are made. In
1371 other words, when you start ADSM, it begins like your concept of a
1372 base job. After that it is in the "incremental" mode. You can
1373 configure the number of "generations" of files to be retained, plus a
1374 retention date after which even old generations are purged. The
1375 database tracks the contents of media and projects the percentage of
1376 each volume that is valid. When the valid content of a volume drops
1377 below a configured percentage, the valid data are migrated to another
1378 volume and the old volume is marked as empty. Note, this requires
1379 ADSM to have an idea of the contents of a client, i.e. marking the
1380 database when an existing file was deleted, but this would solve your
1381 issue of restoring a client without restoring deleted files.
1383 This is pretty far from what bacula now does, but if you are going to
1384 rip things up for Base jobs,.....
1385 Also, the benefits of this are huge for very large shops, especially
1386 with media robots, but are a pain for shops with manual media
1390 > Base jobs sound pretty useful, but I'm not dying for them.
1392 Nobody is dying for them, but when you see what it does, you will die
1395 3. Restoring deleted files: Since I think my comments in (2) above
1396 have low probability of implementation, I'll also suggest that you
1397 could approach the issue of deleted files by a mechanism of having the
1398 fd report to the dir, a list of all files on the client for every
1399 backup job. The dir could note in the database entry for each file
1400 the date that the file was seen. Then if a restore as of date X takes
1401 place, only files that exist from before X until after X would be
1402 restored. Probably the major cost here is the extra date container in
1403 each row of the files table.
1405 Thanks for "listening". I hope some of this helps. If you want to
1406 contact me, please send me an email - I read some but not all of the
1407 mailing list traffic and might miss a reply there.
1409 Please accept my compliments for bacula. It is doing a great job for
1410 me!! I sympathize with you in the need to wrestle with excelence in
1411 execution vs. excelence in feature inclusion.
1416 ==============================
1419 - Design at hierarchial storage for Bacula. Migration and Clone.
1420 - Implement FSM (File System Modules).
1421 - Audit M_ error codes to ensure they are correct and consistent.
1422 - Add variable break characters to lex analyzer.
1423 Either a bit mask or a string of chars so that
1424 the caller can change the break characters.
1425 - Make a single T_BREAK to replace T_COMMA, etc.
1426 - Ensure that File daemon and Storage daemon can
1427 continue a save if the Director goes down (this
1428 is NOT currently the case). Must detect socket error,
1429 buffer messages for later.
1430 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1431 - Add ability to backup to two Storage devices (two SD sessions) at
1432 the same time -- e.g. onsite, offsite.
1433 - Add the ability to consolidate old backup sets (basically do a restore
1434 to tape and appropriately update the catalog). Compress Volume sets.
1435 Might need to spool via file is only one drive is available.
1436 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1437 someway to do so with every volume that has less than x% valid
1441 Migration: Move a backup from one Volume to another
1442 Clone: Copy a backup -- two Volumes
1445 ======================================================
1447 It is somewhat like a Full save becomes an incremental since
1448 the Base job (or jobs) plus other non-base files.
1450 - A Base backup is same as Full backup, just different type.
1451 - New BaseFiles table that contains:
1453 BaseJobId - Base JobId referenced for this FileId (needed ???)
1454 JobId - JobId currently running
1455 FileId - File not backed up, exists in Base Job
1456 FileIndex - FileIndex from Base Job.
1457 i.e. for each base file that exists but is not saved because
1458 it has not changed, the File daemon sends the JobId, BaseId,
1459 FileId, FileIndex back to the Director who creates the DB entry.
1460 - To initiate a Base save, the Director sends the FD
1461 the FileId, and full filename for each file in the Base.
1462 - When the FD finds a Base file, he requests the Director to
1463 send him the full File entry (stat packet plus MD5), or
1464 conversely, the FD sends it to the Director and the Director
1465 says yes or no. This can be quite rapid if the FileId is kept
1466 by the FD for each Base Filename.
1467 - It is probably better to have the comparison done by the FD
1468 despite the fact that the File entry must be sent across the
1470 - An alternative would be to send the FD the whole File entry
1471 from the start. The disadvantage is that it requires a lot of
1472 space. The advantage is that it requires less communications
1474 - The Job record must be updated to indicate that one or more
1476 - At end of Job, FD returns:
1477 1. Count of base files/bytes not written to tape (i.e. matches)
1478 2. Count of base file that were saved i.e. had changed.
1479 - No tape record would be written for a Base file that matches, in the
1480 same way that no tape record is written for Incremental jobs where
1481 the file is not saved because it is unchanged.
1482 - On a restore, all the Base file records must explicitly be
1483 found from the BaseFile tape. I.e. for each Full save that is marked
1484 to have one or more Base Jobs, search the BaseFile for all occurrences
1486 - An optimization might be to make the BaseFile have:
1492 This would avoid the need to explicitly fetch each File record for
1493 the Base job. The Base Job record will be fetched to get the
1494 VolSessionId and VolSessionTime.
1495 =========================================================
1498 ==========================================================
1500 For each Incremental job that is run, there may be files that
1501 were found but not saved because they were locked (this applies
1502 only to Windows). Such a system could send back to the Director
1503 a list of Unsaved files.
1505 - New UnSavedFiles table that contains:
1509 - Then in the next Incremental job, the list of Unsaved Files will be
1510 feed to the FD, who will ensure that they are explicitly chosen even
1511 if standard date/time check would not have selected them.

1553 (just to verify it remembers where it came from, however it can be

1556 There needs to be a table of drive # to devices somewhere - If there are
1557 multiple changers or drives there may not be a 1:1 correspondance between
1558 changer drive number and system device name - and depending on the way the
1559 drives are hooked up to scsi busses, they may not be linearly numbered
1560 from an offset point either.something like
1562 Autochanger drives = 2
1563 Autochanger drive 0 = /dev/nst1
1564 Autochanger drive 1 = /dev/nst2
1565 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1566 times, not just for multidrive changers. For a 1 drive changer, that's
1572 MTX's manpage (1.2.15):
1573 unload [<slotnum>] [ <drivenum> ]
1574 Unloads media from drive <drivenum> into slot
1575 <slotnum>. If <drivenum> is omitted, defaults to
1576 drive 0 (as do all commands). If <slotnum> is
1577 omitted, defaults to the slot that the drive was
1578 loaded from. Note that there's currently no way
1579 to say 'unload drive 1's media to the slot it
1580 came from', other than to explicitly use that
1581 slot number as the destination.AB

1619 Handling removable disks
1621 From: Karl Cunningham <karlc@keckec.com>
1623 My backups are only to hard disk these days, in removable bays. This is my
1624 idea of how a backup to hard disk would work more smoothly. Some of these
1625 things Bacula does already, but I mention them for completeness. If others
1626 have better ways to do this, I'd like to hear about it.
1628 1. Accommodate several disks, rotated similar to how tapes are. Identified
1629 by partition volume ID or perhaps by the name of a subdirectory.
1630 2. Abort & notify the admin if the wrong disk is in the bay.
1631 3. Write backups to different subdirectories for each machine to be backed
1633 4. Volumes (files) get created as needed in the proper subdirectory, one
1635 5. When a disk is recycled, remove or zero all old backup files. This is
1636 important as the disk being recycled may be close to full. This may be
1637 better done manually since the backup files for many machines may be
1638 scattered in many subdirectories.
1643 - Make sure that all do_prompt() calls in Dir check for
1644 -1 (error) and -2 (cancel) returns.
1645 - Fix foreach_jcr() to have free_jcr() inside next().
1646 jcr=jcr_walk_start();
1647 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1650 - A Volume taken from Scratch should take on the retention period
1652 - Correct doc for Maximum Changer Wait (and others) accepting only
1654 - Implement status that shows why a job is being held in reserve, or
1655 rather why none of the drives are suitable.
1656 - Implement a way to disable a drive (so you can use the second
1657 drive of an autochanger, and the first one will not be used or
1659 - Make sure Maximum Volumes is respected in Pools when adding
1660 Volumes (e.g. when pulling a Scratch volume).
1661 - Keep same dcr when switching device ...
1662 - Implement code that makes the Dir aware that a drive is an
1663 autochanger (so the user doesn't need to use the Autochanger = yes
1665 - Make catalog respect ACL.
1666 - Add recycle count to Media record.
1667 - Add initial write date to Media record.
1668 - Fix store_yesno to be store_bitmask.

1692 and verify that other buffers cannot overrun.
1693 - Implement VolumeState as discussed with Arno.
1694 - Add LocationId to update volume
1702 - Add Comment to Media record
1703 - Fix auth compatibility with 1.38
1704 - Update dbcheck to include Log table
1705 - Update llist to include new fields.

1712 - Fix ClientRunBefore/AfterJob compatibility.
1713 - Ensure that connection to daemon failure always indicates what
1714 daemon it was trying to connect to.
