109 - It appears to me that you have run into some sort of race
110 condition where two threads want to use the same Volume and they
111 were both given access. Normally that is no problem. However,
112 one thread wanted the particular Volume in drive 0, but it was
113 loaded into drive 1 so it decided to unload it from drive 1 and
114 then loaded it into drive 0, while the second thread went on
115 thinking that the Volume could be used in drive 1 not realizing
116 that in between time, it was loaded in drive 0.
117 I'll look at the code to see if there is some way we can avoid
118 this kind of problem. Probably the best solution is to make the
119 first thread simply start using the Volume in drive 1 rather than
120 transferring it to drive 0.

155 - Given all the problems with FIFOs, I think the solution is to do something a
156 little different, though I will look at the code and see if there is not some
157 simple solution (i.e. some bug that was introduced). What might be a better
158 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
159 write data to a program rather than the FIFO. For example, suppose you
164 Then, I could imagine if you backup and restore this file with a direct
165 reference as is currently done for fifos, instead, during backup Bacula will
168 /home/kern/my-fifo.backup
170 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
173 /home/kern/my-fifo.restore
175 and send the data backed up to stdout. These programs can either be an
176 executable or a shell script and they need only read/write to stdin/stdout.
178 I think this would give a lot of flexibility to the user without making any
179 significant changes to Bacula.

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

441 1. When jobs are running and bacula for some reason crashes or if I do a
442 restart it remembers and jobs it was running before it crashed or restarted
443 as of now I loose all jobs if I restart it.
445 2. When spooling and in the midway if client is disconnected for instance a
446 laptop bacula completely discard the spool. It will be nice if it can write
447 that spool to tape so there will be some backups for that client if not all.
449 3. We have around 150 clients machines it will be nice to have a option to
450 upgrade all the client machines bacula version automatically.
452 4. Atleast one connection should be reserved for the bconsole so at heavy load
453 I should connect to the director via bconsole which at sometimes I can't
455 5. Another most important feature that is missing, say at 10am I manually
456 started backup of client abc and it was a full backup since client abc has
457 no backup history and at 10.30am bacula again automatically started backup of
458 client abc as that was in the schedule. So now we have 2 multiple Full
459 backups of the same client and if we again try to start a full backup of
460 client backup abc bacula won't complain. That should be fixed.

513 he fills the Volume, then immediately starts reusing it.
514 - Implement copies and stripes.
515 - Add history file to console.
516 - Each file on tape creates a JobMedia record. Peter has 4 million
517 files spread over 10000 tape files and four tapes. A restore takes
518 16 hours to build the restore list.
519 - Add and option to check if the file size changed during backup.
520 - Make sure SD deletes spool files on error exit.
521 - Delete old spool files when SD starts.

538 - Bug: if a job is manually scheduled to run later, it does not appear
539 in any status report and cannot be cancelled.
541 ==== Keeping track of deleted/new files ====
542 - To mark files as deleted, run essentially a Verify to disk, and
543 when a file is found missing (MarkId != JobId), then create
544 a new File record with FileIndex == -1. This could be done
545 by the FD at the same time as the backup.
547 My "trick" for keeping track of deletions is the following.
548 Assuming the user turns on this option, after all the files
549 have been backed up, but before the job has terminated, the
550 FD will make a pass through all the files and send their
551 names to the DIR (*exactly* the same as what a Verify job
552 currently does). This will probably be done at the same
553 time the files are being sent to the SD avoiding a second
554 pass. The DIR will then compare that to what is stored in
555 the catalog. Any files in the catalog but not in what the
556 FD sent will receive a catalog File entry that indicates
557 that at that point in time the file was deleted. This
558 either transmitted to the FD or simultaneously computed in
559 the FD, so that the FD can put a record on the tape that
560 indicates that the file has been deleted at this point.
561 A delete file entry could potentially be one with a FileIndex
562 of 0 or perhaps -1 (need to check if FileIndex is used for
563 some other thing as many of the Bacula fields are "overloaded"
566 During a restore, any file initially picked up by some
567 backup (Full, ...) then subsequently having a File entry
568 marked "delete" will be removed from the tree, so will not
569 be restored. If a file with the same name is later OK it
570 will be inserted in the tree -- this already happens. All
571 will be consistent except for possible changes during the
574 Since I'm on the subject, some of you may be wondering what
575 the utility of the in memory tree is if you are going to
576 restore everything (at least it comes up from time to time
577 on the list). Well, it is still *very* useful because it
578 allows only the last item found for a particular filename
579 (full path) to be entered into the tree, and thus if a file
580 is backed up 10 times, only the last copy will be restored.
581 I recently (last Friday) restored a complete directory, and
582 the Full and all the Differential and Incremental backups
583 spanned 3 Volumes. The first Volume was not even mounted
584 because all the files had been updated and hence backed up
585 since the Full backup was made. In this case, the tree
586 saved me a *lot* of time.
588 Make sure this information is stored on the tape too so
589 that it can be restored directly from the tape.
591 All the code (with the exception of formally generating and
592 saving the delete file entries) already exists in the Verify
593 Catalog command. It explicitly recognizes added/deleted files since
594 the last InitCatalog. It is more or less a "simple" matter of
595 taking that code and adapting it slightly to work for backups.
597 Comments from Martin Simmons (I think they are all covered):
598 Ok, that should cover the basics. There are few issues though:
600 - Restore will depend on the catalog. I think it is better to include the
601 extra data in the backup as well, so it can be seen by bscan and bextract.
603 - I'm not sure if it will preserve multiple hard links to the same inode. Or
604 maybe adding or removing links will cause the data to be dumped again?
606 - I'm not sure if it will handle renamed directories. Possibly it will work
607 by dumping the whole tree under a renamed directory?
609 - It remains to be seen how the backup performance of the DIR's will be
610 affected when comparing the catalog for a large filesystem.
614 How about introducing a Type = MgmtPolicy job type? That job type would
615 be responsible for scanning the Bacula environment looking for specific
616 conditions, and submitting the appropriate jobs for implementing said
620 Name = "Migration-Policy"
622 Policy Selection Job Type = Migrate
623 Scope = "<keyword> <operator> <regexp>"
624 Threshold = "<keyword> <operator> <regexp>"
625 Job Template = <template-name>
628 Where <keyword> is any legal job keyword, <operator> is a comparison
629 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
630 appropriate regexp. I could see an argument for Scope and Threshold
631 being SQL queries if we want to support full flexibility. The
632 Migration-Policy job would then get scheduled as frequently as a site
633 felt necessary (suggested default: every 15 minutes).
638 Name = "Migration-Policy"
640 Policy Selection Job Type = Migration
642 Threshold = "Migration Selection Type = LowestUtil"
643 Job Template = "MigrationTemplate"
646 would select all pools for examination and generate a job based on
647 MigrationTemplate to automatically select the volume with the lowest
648 usage and migrate it's contents to the nextpool defined for that pool.
650 This policy abstraction would be really handy for adjusting the behavior
651 of Bacula according to site-selectable criteria (one thing that pops
652 into mind is Amanda's ability to automatically adjust backup levels
653 depending on various criteria).
659 - Add Pool/Storage override regression test.
660 - Add delete JobId to regression.
661 - Add a regression test for dbcheck.
662 - New test to add bscan to four-concurrent-jobs regression,
663 i.e. after the four-concurrent jobs zap the
664 database as is done in the bscan-test, then use bscan to
665 restore the database, do a restore and compare with the
667 - Add restore of specific JobId to regression (item 3
668 on the restore prompt)
669 - Add IPv6 to regression
670 - Add database test to regression. Test each function like delete,
673 - AntiVir can slow down backups on Win32 systems.
674 - Win32 systems with FAT32 can be much slower than NTFS for
675 more than 1000 files per directory.
679 - A HOLD command to stop all jobs from starting.
680 - A PAUSE command to pause all running jobs ==> release the
682 - Media Type = LTO,LTO-2,LTO-3
683 Media Type Read = LTO,LTO2,LTO3
684 Media Type Write = LTO2, LTO3
686 === From Carsten Menke <bootsy52@gmx.net>
688 Following is a list of what I think in the situations where I'm faced with,
689 could be a usefull enhancement to bacula, which I'm certain other users will
690 benefit from as well.
692 1. NextJob/NextJobs Directive within a Job Resource in the form of
693 NextJobs = job1,job2.
696 I currently solved the problem with running multiple jobs each after each
697 by setting the Max Wait Time for a job to 8 hours, and give
698 the jobs different Priorities. However, there scenarios where
699 1 Job is directly depending on another job, so if the former job fails,
700 the job after it needn't to be run
701 while maybe other jobs should run despite of that
704 A Backup Job and a Verify job, if the backup job fails there is no need to run
705 the verify job, as the backup job already failed. However, one may like
706 to backup the Catalog to disk despite of that the main backup job failed.
709 I see that this is related to the Event Handlers which are on the ToDo
710 list, also it is maybe a good idea to check for the return value and
711 execute different actions based on the return value
714 3. offline capability to bconsole
717 Currently I use a script which I execute within the last Job via the
718 RunAfterJob Directive, to release and eject the tape.
719 So I have to call bconsole "release=Storage-Name" and afterwards
720 mt -f /dev/nst0 eject to get the tape out.
722 If I have multiple Storage Devices, than these may not be /dev/nst0 and
723 I have to modify the script or call it with parameters etc.
724 This would actually not be needed, as everything is already defined
725 in bacula-sd.conf and if I can invoke bconsole with the
726 storage name via $1 in the script than I'm done and information is
729 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
733 For the reason mentioned in 3. to have the ability to call a
734 script with /scripts/foobar %s and in the script use $1
735 to pass the Storage Name to bconsole
737 5. Setting Volume State within a Job Resource
740 Instead of using "Maximum Volume Jobs" in the Pool Resource,
741 I would have the possibilty to define
742 in a Job Resource that after this certain job is run, the Volume State
743 should be set to "Volume State = Used", this give more flexibility (IMHO).
745 6. Localization of Bacula Messages
748 Unfortunatley many,many people I work with don't speak english very well.
749 So if at least the Reporting messages would be localized then they
750 would understand that they have to change the tape,etc. etc.
752 I volunteer to do the german translations, and if I can convince my wife also
753 french and Morre (western african language).
755 7. OK, this is evil, probably bound to security risks and maybe not possible
756 due to the design of bacula.
758 Implementation of Backtics ( `command` ) for shell comand execution to
759 the "Label Format" Directive.
763 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
764 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
765 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
766 the localized name for the day of the week appended to the
767 format string. Then I have the tape labeled automatically with weekday
768 name in the correct language.
770 - Yes, that is surely the case. I probably should turn those into Warning
771 errors. In addition, you just made me think that it might not be bad to
772 add an option to check the file size after backing up the file and
773 report if it changes. This would be done as an option because it would
776 Kern, good idea. If you do do that, mention in the output: file
777 shrunk, or file expanded, just to make it obvious to the user
778 (without having to the refer to file size), just how the file size
781 Would this option be for all file, or just one file? Or a fileset?
782 - Make output from status use html table tags for nicely
783 presenting in a browser.
784 - Can one write tapes faster with 8192 byte block sizes?
785 - Document security problems with the same password for everyone in
786 rpm and Win32 releases.
787 - Browse generations of files.
788 - I've seen an error when my catalog's File table fills up. I
789 then have to recreate the File table with a larger maximum row
790 size. Relevant information is at
791 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
792 "Installing and Configuring MySQL" chapter should talk a bit
793 about this potential problem, and recommend a solution.
794 - For Solaris must use POSIX awk.
795 - Want speed of writing to tape while despooling.
796 - Supported autochanger:
804 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
805 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
806 - Add regex from http://www.pcre.org to Bacula for Win32.
807 - Use only shell tools no make in CDROM package.
808 - Include within include does it work?
809 - Implement a Pool of type Cleaning?
810 - Implement VolReadTime and VolWriteTime in SD
811 - Modify Backing up Your Database to include a bootstrap file.
812 - Think about making certain database errors fatal.
813 - Look at correcting the time jump in the scheduler for daylight
814 savings time changes.
815 - Add a "real" timer to network connections.
816 - Promote to Full = Time period
817 - Check dates entered by user for correctness (month/day/... ranges)
818 - Compress restore Volume listing by date and first file.
819 - Look at patches/bacula_db.b2z postgresql that loops during restore.
821 - Perhaps add read/write programs and/or plugins to FileSets.
822 - How to handle backing up portables ...
823 - Add some sort of guaranteed Interval for upgrading jobs.
824 - Can we write the state file after every job terminates? On Win32
825 the system crashes and the state file is not updated.
828 Documentation to do: (any release a little bit at a time)
829 - Doc to do unmount before removing magazine.
830 - Alternative to static linking "ldd prog" save all binaries listed,
831 restore them and point LD_LIBRARY_PATH to them.
832 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
833 - Document query file format.
834 - Add more documentation for bsr files.
835 - Document problems with Verify and pruning.
836 - Document how to use multiple databases.
837 - VXA drives have a "cleaning required"
838 indicator, but Exabyte recommends preventive cleaning after every 75
841 In this context, it should be noted that Exabyte has a command-line
842 vxatool utility available for free download. (The current version is
843 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
844 test the drive, unload tapes, change drive settings, flash new firmware,
846 Of particular interest in this context is that vxatool <device> -i will
847 report, among other details, the time since last cleaning in tape motion
848 minutes. This information can be retrieved (and settings changed, for
849 that matter) through the generic-SCSI device even when Bacula has the
850 regular tape device locked. (Needless to say, I don't recommend
851 changing tape settings while a job is running.)
852 - Lookup HP cleaning recommendations.
853 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
854 - Document doing table repair
857 ===================================
858 - Add macro expansions in JobDefs.
859 Run Before Job = "SomeFile %{Level} %{Client}"
860 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
861 - Use non-blocking network I/O but if no data is available, use
863 - Use gather write() for network I/O.
864 - Autorestart on crash.
865 - Add bandwidth limiting.
866 - Add acks every once and a while from the SD to keep
867 the line from timing out.
868 - When an error in input occurs and conio beeps, you can back
869 up through the prompt.
870 - Detect fixed tape block mode during positioning by looking at
871 block numbers in btape "test". Possibly adjust in Bacula.
872 - Fix list volumes to output volume retention in some other
873 units, perhaps via a directive.
874 - If opening a tape in read/write mode fails attempt to open
875 it in read-only mode, and mark the tape for read only.
876 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
877 with multiple priorities.
878 - If you use restore replace=never, the directory attributes for
879 non-existent directories will not be restored properly.
881 - see lzma401.zip in others directory for new compression
883 - Minimal autochanger handling in Bacula and in btape.
884 - Look into how tar does not save sockets and the possiblity of
885 not saving them in Bacula (Martin Simmons reported this).
886 - Fix restore jobs so that multiple jobs can run if they
887 are not using the same tape(s).
888 - Allow the user to select JobType for manual pruning/purging.
889 - bscan does not put first of two volumes back with all info in
891 - Implement the FreeBSD nodump flag in chflags.
892 - Figure out how to make named console messages go only to that
893 console and to the non-restricted console (new console class?).
894 - Make restricted console prompt for password if *ask* is set or
895 perhaps if password is undefined.
896 - Implement "from ISO-date/time every x hours/days/weeks/months" in
899 ==== from Marc Schoechlin
900 - the help-command should be more verbose
901 (it should explain the paramters of the different
903 -> its time-comsuming to consult the manual anytime
904 you need a special parameter
905 -> maybe its more easy to maintain this, if the
906 descriptions of that commands are outsourced to
908 - the cd-command should allow complete paths
909 i.e. cd /foo/bar/foo/bar
910 -> if a customer mails me the path to a certain file,
911 its faster to enter the specified directory
912 - if the password is not configured in bconsole.conf
913 you should be asked for it.
914 -> sometimes you like to do restore on a customer-machine
915 which shouldnt know the password for bacula.
916 -> adding the password to the file favours admins
917 to forget to remove the password after usage
919 the protection of that file is less important
920 - long-listed-output of commands should be scrollable
921 like the unix more/less-command does
922 -> if someone runs 200 and more machines, the lists could
923 be a little long and complex
924 - command-output should be shown column by column
925 to reduce scrolling and to increase clarity
927 - lsmark should list the selected files with full
929 - wildcards for selecting and file and directories would be nice
930 - any actions should be interuptable with STRG+C
931 - command-expansion would be pretty cool
933 - When the replace Never option is set, new directory permissions
934 are not restored. See bug 213. To fix this requires creating a
935 list of newly restored directories so that those directory
936 permissions *can* be restored.
937 - Compaction of Disk space by "migrating" Volumes that have pruned
938 Jobs (what criteria? size, #jobs, time).
939 - Add prune all command
940 - Document fact that purge can destroy a part of a restore by purging
941 one volume while others remain valid -- perhaps mark Jobs.
942 - Add multiple-media-types.txt
943 - look at mxt-changer.html
944 - Make ? do a help command (no return needed).
945 - Implement restore directory.
946 - Document streams and how to implement them.
947 - Try not to re-backup a file if a new hard link is added.
948 - Add feature to backup hard links only, but not the data.
949 - Fix stream handling to be simpler.
950 - Add Priority and Bootstrap to Run a Job.
951 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
953 - Remove View FileSet button from Run a Job dialog.
954 - Handle prompt for restore job at end of Restore command.
955 - Add display of total selected files to Restore window.
956 - Add tree pane to left of window.
957 - Add progress meter.
958 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
959 - Document writing to a CD/DVD with Bacula.
960 - Add a "base" package to the window installer for pthreadsVCE.dll
961 which is needed by all packages.
962 - Add message to user to check for fixed block size when the forward
963 space test fails in btape.
964 - When unmarking a directory check if all files below are unmarked and
965 then remove the + flag -- in the restore tree.
966 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
967 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
968 - Revisit the question of multiple Volumes (disk) on a single device.
969 - Add a block copy option to bcopy.
970 - Investigate adding Mac Resource Forks.
971 - Finish work on Gnome restore GUI.
972 - Fix "llist jobid=xx" where no fileset or client exists.
973 - For each job type (Admin, Restore, ...) require only the really necessary
974 fields.- Pass Director resource name as an option to the Console.
975 - Add a "batch" mode to the Console (no unsolicited queries, ...).
976 - Add a .list all files in the restore tree (probably also a list all files)
977 Do both a long and short form.
978 - Allow browsing the catalog to see all versions of a file (with
979 stat data on each file).
980 - Restore attributes of directory if replace=never set but directory
982 - Use SHA1 on authentication if possible.
983 - See comtest-xxx.zip for Windows code to talk to USB.
984 - Add John's appended files:
985 Appended = { /files/server/logs/http/*log }
986 and such files would be treated as follows.On a FULL backup, they would
987 be backed up like any other file.On an INCREMENTAL backup, where a
988 previous INCREMENTAL or FULL was already in thecatalogue and the length
989 of the file wasgreater than the length of the last backup, only thedata
990 added since the last backup will be dumped.On an INCREMENTAL backup, if
991 the length of the file is less than thelength of the file with the same
992 name last backed up, the completefile is dumped.On Windows systems, with
993 creation date of files, we can be evensmarter about this and not count
994 entirely upon the length.On a restore, the full and all incrementals
995 since it will beapplied in sequence to restore the file.
996 - Check new HAVE_WIN32 open bits.
997 - Check if the tape has moved before writing.
998 - Handling removable disks -- see below:
999 - Keep track of tape use time, and report when cleaning is necessary.
1000 - Add FromClient and ToClient keywords on restore command (or
1001 BackupClient RestoreClient).
1002 - Implement a JobSet, which groups any number of jobs. If the
1003 JobSet is started, all the jobs are started together.
1004 Allow Pool, Level, and Schedule overrides.
1005 - Enhance cancel to timeout BSOCK packets after a specific delay.
1006 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1007 ua_status.!!! Thanks to Alan Brown for this tip.
1008 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1009 correctly for multiple simultaneous jobs.
1010 - Correct code so that FileSet MD5 is calculated for < and | filename
1012 - Implement the Media record flag that indicates that the Volume does disk
1014 - Implement VolAddr, which is used when Volume is addressed like a disk,
1015 and form it from VolFile and VolBlock.
1016 - Make multiple restore jobs for multiple media types specifying
1017 the proper storage type.
1018 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1019 pointer (rec) to try_repositioning().
1020 - Look at extracting Win data from BackupRead.
1021 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1022 which would take precidence over the Catalog "JobRetention".
1023 - Implement Label Format in Add and Label console commands.
1024 - Possibly up network buffers to 65K. Put on variable.
1025 - Put email tape request delays on one or more variables. User wants
1026 to cancel the job after a certain time interval. Maximum Mount Wait?
1027 - Job, Client, Device, Pool, or Volume?
1028 Is it possible to make this a directive which is *optional* in multiple
1029 resources, like Level? If so, I think I'd make it an optional directive
1030 in Job, Client, and Pool, with precedence such that Job overrides Client
1031 which in turn overrides Pool.
1033 - New Storage specifications:
1034 - Want to write to multiple storage devices simultaneously
1035 - Want to write to multiple storage devices sequentially (in one job)
1036 - Want to read/write simultaneously
1037 - Key is MediaType -- it must match
1039 Passed to SD as a sort of BSR record called Storage Specification
1043 MediaType -> Next MediaType
1045 Device -> Next Device
1047 Allow multiple Storage specifications
1055 Allow Multiple Pool specifications (note, Pool currently
1057 Allow Multiple MediaType specifications in Dir conf
1058 Allow Multiple Device specifications in Dir conf
1059 Perhaps keep this in a single SSR
1060 Tie a Volume to a specific device by using a MediaType that
1061 is contained in only one device.
1062 In SD allow Device to have Multiple MediaTypes
1064 - Ideas from Jerry Scharf:
1065 First let's point out some big pluses that bacula has for this
1067 more importantly it's active. Thank you so much for that
1068 even more important, it's not flaky
1069 it has an open access catalog, opening many possibilities
1070 it's pushing toward heterogeneous systems capability
1072 Macintosh file client
1073 macs are an interesting niche, but I fear a server is a rathole
1074 working bare iron recovery for windows
1075 the option for inc/diff backups not reset on fileset revision
1076 a) use both change and inode update time against base time
1077 b) do the full catalog check (expensive but accurate)
1078 sizing guide (how much system is needed to back up N systems/files)
1079 consultants on using bacula in building a disaster recovery system
1080 an integration guide
1081 or how to get at fancy things that one could do with bacula
1082 logwatch code for bacula logs (or similar)
1083 linux distro inclusion of bacula (brings good and bad, but necessary)
1084 win2k/XP server capability (icky but you asked)
1085 support for Oracle database ??
1087 - Look at adding SQL server and Exchange support for Windows.
1088 - Make dev->file and dev->block_num signed integers so that -1 can
1089 be an invalid value which happens with BSR.
1090 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1091 is needed to properly specify ranges.
1092 - Add progress of files/bytes to SD and FD.
1093 - Print warning message if FileId > 4 billion
1094 - do a "messages" before the first prompt in Console
1095 - Client does not show busy during Estimate command.
1096 - Implement Console mtx commands.
1097 - Implement a Mount Command and an Unmount Command where
1098 the users could specify a system command to be performed
1099 to do the mount, after which Bacula could attempt to
1100 read the device. This is for Removeable media such as a CDROM.
1101 - Most likely, this mount command would be invoked explicitly
1102 by the user using the current Console "mount" and "unmount"
1103 commands -- the Storage Daemon would do the right thing
1104 depending on the exact nature of the device.
1105 - As with tape drives, when Bacula wanted a new removable
1106 disk mounted, it would unmount the old one, and send a message
1107 to the user, who would then use "mount" as described above
1108 once he had actually inserted the disk.
1109 - Implement dump/print label to UA
1110 - Spool to disk only when the tape is full, then when a tape is hung move
1112 - bextract is sending everything to the log file ****FIXME****
1113 - Allow multiple Storage specifications (or multiple names on
1114 a single Storage specification) in the Job record. Thus a job
1115 can be backed up to a number of storage devices.
1116 - Implement some way for the File daemon to contact the Director
1117 to start a job or pass its DHCP obtained IP number.
1118 - Implement a query tape prompt/replace feature for a console
1119 - Copy console @ code to gnome2-console
1120 - Make AES the only encryption algorithm see
1121 http://csrc.nist.gov/CryptoToolkit/aes/). It's
1122 an officially adopted standard, has survived peer
1123 review, and provides keys up to 256 bits.
1124 - Take a careful look at SetACL http://setacl.sourceforge.net
1125 - Make tree walk routines like cd, ls, ... more user friendly
1126 by handling spaces better.
1127 - Make sure that Bacula rechecks the tape after the 20 min wait.
1128 - Set IO_NOWAIT on Bacula TCP/IP packets.
1129 - Try doing a raw partition backup and restore by mounting a
1131 - From Lars Kellers:
1132 Yes, it would allow to highly automatic the request for new tapes. If a
1133 tape is empty, bacula reads the barcodes (native or simulated), and if
1134 an unused tape is found, it runs the label command with all the
1135 necessary parameters.
1137 By the way can bacula automatically "move" an empty/purged volume say
1138 in the "short" pool to the "long" pool if this pool runs out of volume
1140 - What to do about "list files job=xxx".
1141 - Get and test MySQL 4.0
1142 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1143 file descriptor leak in Bacula.
1144 - Implement WrapCounters in Counters.
1145 - Add heartbeat from FD to SD if hb interval expires.
1146 - Can we dynamically change FileSets?
1147 - If pool specified to label command and Label Format is specified,
1148 automatically generate the Volume name.
1149 - Why can't SQL do the filename sort for restore?
1150 - Add ExhautiveRestoreSearch
1151 - Look at the possibility of loading only the necessary
1152 data into the restore tree (i.e. do it one directory at a
1153 time as the user walks through the tree).
1154 - Possibly use the hash code if the user selects all for a restore command.
1155 - Fix "restore all" to bypass building the tree.
1156 - Prohibit backing up archive device (findlib/find_one.c:128)
1157 - Implement Release Device in the Job resource to unmount a drive.
1158 - Implement Acquire Device in the Job resource to mount a drive,
1159 be sure this works with admin jobs so that the user can get
1160 prompted to insert the correct tape. Possibly some way to say to
1161 run the job but don't save the files.
1162 - Make things like list where a file is saved case independent for
1165 - Use autochanger to handle multiple devices.
1166 - On Windows with very long path names, it may be impossible to create
1167 a file (and thus restore it) because the total length is too long.
1168 We must cd into the directory then create the file without the
1170 - Implement a Recycle command
1171 - Test a second language e.g. french.
1172 - Start working on Base jobs.
1173 - Implement UnsavedFiles DB record.
1174 - From Phil Stracchino:
1175 It would probably be a per-client option, and would be called
1176 something like, say, "Automatically purge obsoleted jobs". What it
1177 would do is, when you successfully complete a Differential backup of a
1178 client, it would automatically purge all Incremental backups for that
1179 client that are rendered redundant by that Differential. Likewise,
1180 when a Full backup on a client completed, it would automatically purge
1181 all Differential and Incremental jobs obsoleted by that Full backup.
1182 This would let people minimize the number of tapes they're keeping on
1183 hand without having to master the art of retention times.
1184 - When doing a Backup send all attributes back to the Director, who
1185 would then figure out what files have been deleted.
1186 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1187 explicit permission to do so. It should also mark the tape in error
1188 if there is an error.
1189 - Cancel waiting for Client connect in SD if FD goes away.
1191 - Implement timeout in response() when it should come quickly.
1192 - Implement a Slot priority (loaded/not loaded).
1193 - Implement "vacation" Incremental only saves.
1194 - Implement create "FileSet"?
1195 - Add prefixlinks to where or not where absolute links to FD.
1196 - Issue message to mount a new tape before the rewind.
1197 - Simplified client job initiation for portables.
1198 - If SD cannot open a drive, make it periodically retry.
1199 - Add more of the config info to the tape label.
1201 - If tape is marked read-only, then try opening it read-only rather than
1202 failing, and remember that it cannot be written.
1203 - Refine SD waiting output:
1204 Device is being positioned
1205 > Device is being positioned for append
1206 > Device is being positioned to file x
1208 - Figure out some way to estimate output size and to avoid splitting
1209 a backup across two Volumes -- this could be useful for writing CDROMs
1210 where you really prefer not to have it split -- not serious.
1211 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1212 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1213 actual data on the Volume and compare it.
1214 - Implement Bacula plugins -- design API
1215 - Make bcopy read through bad tape records.
1216 - Program files (i.e. execute a program to read/write files).
1217 Pass read date of last backup, size of file last time.
1218 - Add Signature type to File DB record.
1219 - CD into subdirectory when open()ing files for backup to
1220 speed up things. Test with testfind().
1221 - Priority job to go to top of list.
1222 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1223 - Implement some way for the Console to dynamically create a job.
1224 - Solaris -I on tar for include list
1225 - Need a verbose mode in restore, perhaps to bsr.
1226 - bscan without -v is too quiet -- perhaps show jobs.
1227 - Add code to reject whole blocks if not wanted on restore.
1228 - Check if we can increase Bacula FD priorty in Win2000
1229 - Make sure the MaxVolFiles is fully implemented in SD
1230 - Check if both CatalogFiles and UseCatalog are set to SD.
1231 - Possibly add email to Watchdog if drive is unmounted too
1232 long and a job is waiting on the drive.
1233 - After unmount, if restore job started, ask to mount.
1234 - Add UA rc and history files.
1235 - put termcap (used by console) in ./configure and
1236 allow -with-termcap-dir.
1237 - Fix Autoprune for Volumes to respect need for full save.
1238 - Compare tape to Client files (attributes, or attributes and data)
1239 - Make all database Ids 64 bit.
1240 - Allow console commands to detach or run in background.
1241 - Fix status delay on storage daemon during rewind.
1242 - Add SD message variables to control operator wait time
1243 - Maximum Operator Wait
1244 - Minimum Message Interval
1245 - Maximum Message Interval
1246 - Send Operator message when cannot read tape label.
1247 - Verify level=Volume (scan only), level=Data (compare of data to file).
1248 Verify level=Catalog, level=InitCatalog
1250 - Add keyword search to show command in Console.
1251 - Events : tape has more than xxx bytes.
1252 - Complete code in Bacula Resources -- this will permit
1253 reading a new config file at any time.
1254 - Handle ctl-c in Console
1255 - Implement script driven addition of File daemon to config files.
1256 - Think about how to make Bacula work better with File (non-tape) archives.
1257 - Write Unix emulator for Windows.
1258 - Put memory utilization in Status output of each daemon
1259 if full status requested or if some level of debug on.
1260 - Make database type selectable by .conf files i.e. at runtime
1261 - Set flag for uname -a. Add to Volume label.
1262 - Restore files modified after date
1263 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1264 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1265 - Timout a job or terminate if link goes down, or reopen link and query.
1266 - Concept of precious tapes (cannot be reused).
1267 - Make bcopy copy with a single tape drive.
1268 - Permit changing ownership during restore.

1282 - Autolabel should be specified by DIR instead of SD.
1284 - Add media capacity
1285 - AutoScan (check checksum of tape)
1286 - Format command = "format /dev/nst0"
1290 - Seek resolution (usually corresponds to buffer size)
1291 - EODErrorCode=ENOSPC or code
1292 - Partial Read error code
1293 - Partial write error code
1294 - Nonformatted read error
1295 - Nonformatted write error
1296 - WriteProtected error
1300 - IgnoreCloseErrors=yes
1310 - FD sends unsaved file list to Director at end of job (see
1312 - File daemon should build list of files skipped, and then
1313 at end of save retry and report any errors.
1314 - Write a Storage daemon that uses pipes and
1315 standard Unix programs to write to the tape.
1317 - Need something that monitors the JCR queue and
1318 times out jobs by asking the deamons where they are.
1319 - Enhance Jmsg code to permit buffering and saving to disk.
1320 - device driver = "xxxx" for drives.
1321 - Verify from Volume
1322 - Ensure that /dev/null works
1323 - Need report class for messages. Perhaps
1324 report resource where report=group of messages
1325 - enhance scan_attrib and rename scan_jobtype, and
1326 fill in code for "since" option
1327 - Director needs a time after which the report status is sent
1328 anyway -- or better yet, a retry time for the job.
1329 - Don't reschedule a job if previous incarnation is still running.
1330 - Some way to automatically backup everything is needed????
1331 - Need a structure for pending actions:
1333 - termination status (part of buffered msgs?)
1335 Read, Write, Clean, Delete
1336 - Login to Bacula; Bacula users with different permissions:
1337 owner, group, user, quotas
1338 - Store info on each file system type (probably in the job header on tape.
1339 This could be the output of df; or perhaps some sort of /etc/mtab record.
1341 ========= ideas ===============
1342 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1343 To: <kern@sibbald.com>
1344 Subject: RE: [Bacula-users] future large programming jobs
1345 Date: Thu, 26 Feb 2004 11:34:54 -0600
1347 I noticed the subject thread and thought I would offer the following
1348 merely as sources of ideas, i.e. something to think about, not even as
1349 strong as a request. In my former life (before retiring) I often
1350 dealt with backups and storage management issues/products as a
1351 developer and as a consultant. I am currently migrating my personal
1352 network from amanda to bacula specifically because of the ability to
1353 cross media boundaries during storing backups.
1354 Are you familiar with the commercial product called ADSM (I think IBM
1355 now sells it under the Tivoli label)? It has a couple of interesting
1356 ideas that may apply to the following topics.
1358 1. Migration: Consider that when you need to restore a system, there
1359 may be pressure to hurry. If all the information for a single client
1360 can eventually end up on the same media (and in chronological order),
1361 the restore is facillitated by not having to search past information
1362 from other clients. ADSM has the concept of "client affinity" that
1363 may be associated with it's storage pools. It seems to me that this
1364 concept (as an optional feature) might fit in your architecture for
1367 ADSM also has the concept of defining one or more storage pools as
1368 "copy pools" (almost mirrors, but only in the sense of contents).
1369 These pools provide the ability to have duplicte data stored both
1370 onsite and offsite. The copy process can be scheduled to be handled
1371 by their storage manager during periods when there is no backup
1372 activity. Again, the migration process might be a place to consider
1373 implementing something like this.
1376 > It strikes me that it would be very nice to be able to do things
1378 > have the Job(s) backing up the machines run, and once they have all
1379 > completed, start a migration job to copy the data from disks Volumes

1384 > mechanism described below would probably make it very easy.
1386 This is the goal. In the first step (before events), you simply
1388 the Migration to tape later.
1390 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1391 the database. Once a file (unique by path and metadata such as dates,
1392 size, ownership, etc.) is in a copy pool, no more copies are made. In
1393 other words, when you start ADSM, it begins like your concept of a
1394 base job. After that it is in the "incremental" mode. You can
1395 configure the number of "generations" of files to be retained, plus a
1396 retention date after which even old generations are purged. The
1397 database tracks the contents of media and projects the percentage of
1398 each volume that is valid. When the valid content of a volume drops
1399 below a configured percentage, the valid data are migrated to another
1400 volume and the old volume is marked as empty. Note, this requires
1401 ADSM to have an idea of the contents of a client, i.e. marking the
1402 database when an existing file was deleted, but this would solve your
1403 issue of restoring a client without restoring deleted files.
1405 This is pretty far from what bacula now does, but if you are going to
1406 rip things up for Base jobs,.....
1407 Also, the benefits of this are huge for very large shops, especially
1408 with media robots, but are a pain for shops with manual media
1412 > Base jobs sound pretty useful, but I'm not dying for them.
1414 Nobody is dying for them, but when you see what it does, you will die
1417 3. Restoring deleted files: Since I think my comments in (2) above
1418 have low probability of implementation, I'll also suggest that you
1419 could approach the issue of deleted files by a mechanism of having the
1420 fd report to the dir, a list of all files on the client for every
1421 backup job. The dir could note in the database entry for each file
1422 the date that the file was seen. Then if a restore as of date X takes
1423 place, only files that exist from before X until after X would be
1424 restored. Probably the major cost here is the extra date container in
1425 each row of the files table.
1427 Thanks for "listening". I hope some of this helps. If you want to
1428 contact me, please send me an email - I read some but not all of the
1429 mailing list traffic and might miss a reply there.
1431 Please accept my compliments for bacula. It is doing a great job for
1432 me!! I sympathize with you in the need to wrestle with excelence in
1433 execution vs. excelence in feature inclusion.
1438 ==============================
1441 - Design at hierarchial storage for Bacula. Migration and Clone.
1442 - Implement FSM (File System Modules).
1443 - Audit M_ error codes to ensure they are correct and consistent.
1444 - Add variable break characters to lex analyzer.
1445 Either a bit mask or a string of chars so that
1446 the caller can change the break characters.
1447 - Make a single T_BREAK to replace T_COMMA, etc.
1448 - Ensure that File daemon and Storage daemon can
1449 continue a save if the Director goes down (this
1450 is NOT currently the case). Must detect socket error,
1451 buffer messages for later.
1452 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1453 - Add ability to backup to two Storage devices (two SD sessions) at
1454 the same time -- e.g. onsite, offsite.
1455 - Add the ability to consolidate old backup sets (basically do a restore
1456 to tape and appropriately update the catalog). Compress Volume sets.
1457 Might need to spool via file is only one drive is available.
1458 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1459 someway to do so with every volume that has less than x% valid
1463 Migration: Move a backup from one Volume to another
1464 Clone: Copy a backup -- two Volumes
1466 Bacula Migration is based on Jobs (apparently Networker is file by file).
1468 Migration triggered by:
1472 Highwater mark (keep total size)
1477 ======================================================
1479 It is somewhat like a Full save becomes an incremental since
1480 the Base job (or jobs) plus other non-base files.
1482 - A Base backup is same as Full backup, just different type.
1483 - New BaseFiles table that contains:
1485 BaseJobId - Base JobId referenced for this FileId (needed ???)
1486 JobId - JobId currently running
1487 FileId - File not backed up, exists in Base Job
1488 FileIndex - FileIndex from Base Job.
1489 i.e. for each base file that exists but is not saved because
1490 it has not changed, the File daemon sends the JobId, BaseId,
1491 FileId, FileIndex back to the Director who creates the DB entry.
1492 - To initiate a Base save, the Director sends the FD
1493 the FileId, and full filename for each file in the Base.
1494 - When the FD finds a Base file, he requests the Director to
1495 send him the full File entry (stat packet plus MD5), or
1496 conversely, the FD sends it to the Director and the Director
1497 says yes or no. This can be quite rapid if the FileId is kept
1498 by the FD for each Base Filename.
1499 - It is probably better to have the comparison done by the FD
1500 despite the fact that the File entry must be sent across the
1502 - An alternative would be to send the FD the whole File entry
1503 from the start. The disadvantage is that it requires a lot of
1504 space. The advantage is that it requires less communications
1506 - The Job record must be updated to indicate that one or more
1508 - At end of Job, FD returns:
1509 1. Count of base files/bytes not written to tape (i.e. matches)
1510 2. Count of base file that were saved i.e. had changed.
1511 - No tape record would be written for a Base file that matches, in the
1512 same way that no tape record is written for Incremental jobs where
1513 the file is not saved because it is unchanged.
1514 - On a restore, all the Base file records must explicitly be
1515 found from the BaseFile tape. I.e. for each Full save that is marked
1516 to have one or more Base Jobs, search the BaseFile for all occurrences
1518 - An optimization might be to make the BaseFile have:
1524 This would avoid the need to explicitly fetch each File record for
1525 the Base job. The Base Job record will be fetched to get the
1526 VolSessionId and VolSessionTime.
1527 =========================================================
1530 ==========================================================
1532 For each Incremental job that is run, there may be files that
1533 were found but not saved because they were locked (this applies
1534 only to Windows). Such a system could send back to the Director
1535 a list of Unsaved files.
1537 - New UnSavedFiles table that contains:
1541 - Then in the next Incremental job, the list of Unsaved Files will be
1542 feed to the FD, who will ensure that they are explicitly chosen even
1543 if standard date/time check would not have selected them.

1588 There needs to be a table of drive # to devices somewhere - If there are
1589 multiple changers or drives there may not be a 1:1 correspondance between
1590 changer drive number and system device name - and depending on the way the
1591 drives are hooked up to scsi busses, they may not be linearly numbered
1592 from an offset point either.something like
1594 Autochanger drives = 2
1595 Autochanger drive 0 = /dev/nst1
1596 Autochanger drive 1 = /dev/nst2
1597 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1598 times, not just for multidrive changers. For a 1 drive changer, that's
1604 MTX's manpage (1.2.15):
1605 unload [<slotnum>] [ <drivenum> ]
1606 Unloads media from drive <drivenum> into slot
1607 <slotnum>. If <drivenum> is omitted, defaults to
1608 drive 0 (as do all commands). If <slotnum> is
1609 omitted, defaults to the slot that the drive was
1610 loaded from. Note that there's currently no way
1611 to say 'unload drive 1's media to the slot it
1612 came from', other than to explicitly use that
1613 slot number as the destination.AB

1651 Handling removable disks
1653 From: Karl Cunningham <karlc@keckec.com>
1655 My backups are only to hard disk these days, in removable bays. This is my
1656 idea of how a backup to hard disk would work more smoothly. Some of these
1657 things Bacula does already, but I mention them for completeness. If others
1658 have better ways to do this, I'd like to hear about it.
1660 1. Accommodate several disks, rotated similar to how tapes are. Identified
1661 by partition volume ID or perhaps by the name of a subdirectory.
1662 2. Abort & notify the admin if the wrong disk is in the bay.
1663 3. Write backups to different subdirectories for each machine to be backed
1665 4. Volumes (files) get created as needed in the proper subdirectory, one
1667 5. When a disk is recycled, remove or zero all old backup files. This is
1668 important as the disk being recycled may be close to full. This may be
1669 better done manually since the backup files for many machines may be
1670 scattered in many subdirectories.
1675 - Make sure that all do_prompt() calls in Dir check for
1676 -1 (error) and -2 (cancel) returns.
1677 - Fix foreach_jcr() to have free_jcr() inside next().
1678 jcr=jcr_walk_start();
1679 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1682 - A Volume taken from Scratch should take on the retention period
1684 - Correct doc for Maximum Changer Wait (and others) accepting only
1686 - Implement status that shows why a job is being held in reserve, or
1687 rather why none of the drives are suitable.
1688 - Implement a way to disable a drive (so you can use the second
1689 drive of an autochanger, and the first one will not be used or
1691 - Make sure Maximum Volumes is respected in Pools when adding
1692 Volumes (e.g. when pulling a Scratch volume).
1693 - Keep same dcr when switching device ...
1694 - Implement code that makes the Dir aware that a drive is an
1695 autochanger (so the user doesn't need to use the Autochanger = yes
1697 - Make catalog respect ACL.
1698 - Add recycle count to Media record.
1699 - Add initial write date to Media record.
1700 - Fix store_yesno to be store_bitmask.
