111 better machine-readable output like "Ok" or "Error busy"
112 .move eject device=xxx toslot=yyy the same as above, but with a new
113 target slot. The catalog should be updated accordingly.

117 - It appears to me that you have run into some sort of race
118 condition where two threads want to use the same Volume and they
119 were both given access. Normally that is no problem. However,
120 one thread wanted the particular Volume in drive 0, but it was
121 loaded into drive 1 so it decided to unload it from drive 1 and
122 then loaded it into drive 0, while the second thread went on
123 thinking that the Volume could be used in drive 1 not realizing
124 that in between time, it was loaded in drive 0.
125 I'll look at the code to see if there is some way we can avoid
126 this kind of problem. Probably the best solution is to make the
127 first thread simply start using the Volume in drive 1 rather than
128 transferring it to drive 0.
129 - Fix re-read of last block to check if job has actually written
130 a block, and check if block was written by a different job

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

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

435 1. When jobs are running and bacula for some reason crashes or if I do a
436 restart it remembers and jobs it was running before it crashed or restarted
437 as of now I loose all jobs if I restart it.
439 2. When spooling and in the midway if client is disconnected for instance a
440 laptop bacula completely discard the spool. It will be nice if it can write
441 that spool to tape so there will be some backups for that client if not all.
443 3. We have around 150 clients machines it will be nice to have a option to
444 upgrade all the client machines bacula version automatically.
446 4. Atleast one connection should be reserved for the bconsole so at heavy load
447 I should connect to the director via bconsole which at sometimes I can't
449 5. Another most important feature that is missing, say at 10am I manually
450 started backup of client abc and it was a full backup since client abc has
451 no backup history and at 10.30am bacula again automatically started backup of
452 client abc as that was in the schedule. So now we have 2 multiple Full
453 backups of the same client and if we again try to start a full backup of
454 client backup abc bacula won't complain. That should be fixed.
456 - Fix bpipe.c so that it does not modify results pointer.
457 ***FIXME*** calling sequence should be changed.
458 - For Windows disaster recovery see http://unattended.sf.net/
459 - regardless of the retention period, Bacula will not prune the
460 last Full, Diff, or Inc File data until a month after the
461 retention period for the last Full backup that was done.
462 - update volume=xxx --- add status=Full
463 - Remove old spool files on startup.

475 - Why is SpoolDirectory = /home/bacula/spool; not reported
476 as an error when writing a DVD?
477 - Make bootstrap file handle multiple MediaTypes (SD)
478 - Remove all old Device resource code in Dir and code to pass it
479 back in SD -- better, rework it to pass back device statistics.
480 - Check locking of resources -- be sure to lock devices where previously
481 resources were locked.
482 - The last part is left in the spool dir.
485 - In restore don't compare byte count on a raw device -- directory
486 entry does not contain bytes.

498 and possibly manipulating the autochanger (much asked for).
499 - Add start/end date editing in messages (%t %T, %e?) ...
500 - Add ClientDefs similar to JobDefs.
501 - Print more info when bextract -p accepts a bad block.
502 - Fix FD JobType to be set before RunBeforeJob in FD.
503 - Look at adding full Volume and Pool information to a Volume
504 label so that bscan can get *all* the info.
505 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
506 and there is only one volume in the pool, refuse to do it -- otherwise
507 he fills the Volume, then immediately starts reusing it.
508 - Implement copies and stripes.
509 - Add history file to console.
510 - Each file on tape creates a JobMedia record. Peter has 4 million
511 files spread over 10000 tape files and four tapes. A restore takes
512 16 hours to build the restore list.
513 - Add and option to check if the file size changed during backup.
514 - Make sure SD deletes spool files on error exit.
515 - Delete old spool files when SD starts.
516 - When labeling tapes, if you enter 000026, Bacula uses
517 the tape index rather than the Volume name 000026.
518 - Add offline tape command to Bacula console.

532 - Bug: if a job is manually scheduled to run later, it does not appear
533 in any status report and cannot be cancelled.
535 ==== Keeping track of deleted/new files ====
536 - To mark files as deleted, run essentially a Verify to disk, and
537 when a file is found missing (MarkId != JobId), then create
538 a new File record with FileIndex == -1. This could be done
539 by the FD at the same time as the backup.
541 My "trick" for keeping track of deletions is the following.
542 Assuming the user turns on this option, after all the files
543 have been backed up, but before the job has terminated, the
544 FD will make a pass through all the files and send their
545 names to the DIR (*exactly* the same as what a Verify job
546 currently does). This will probably be done at the same
547 time the files are being sent to the SD avoiding a second
548 pass. The DIR will then compare that to what is stored in
549 the catalog. Any files in the catalog but not in what the
550 FD sent will receive a catalog File entry that indicates
551 that at that point in time the file was deleted. This
552 either transmitted to the FD or simultaneously computed in
553 the FD, so that the FD can put a record on the tape that
554 indicates that the file has been deleted at this point.
555 A delete file entry could potentially be one with a FileIndex
556 of 0 or perhaps -1 (need to check if FileIndex is used for
557 some other thing as many of the Bacula fields are "overloaded"
560 During a restore, any file initially picked up by some
561 backup (Full, ...) then subsequently having a File entry
562 marked "delete" will be removed from the tree, so will not
563 be restored. If a file with the same name is later OK it
564 will be inserted in the tree -- this already happens. All
565 will be consistent except for possible changes during the
568 Since I'm on the subject, some of you may be wondering what
569 the utility of the in memory tree is if you are going to
570 restore everything (at least it comes up from time to time
571 on the list). Well, it is still *very* useful because it
572 allows only the last item found for a particular filename
573 (full path) to be entered into the tree, and thus if a file
574 is backed up 10 times, only the last copy will be restored.
575 I recently (last Friday) restored a complete directory, and
576 the Full and all the Differential and Incremental backups
577 spanned 3 Volumes. The first Volume was not even mounted
578 because all the files had been updated and hence backed up
579 since the Full backup was made. In this case, the tree
580 saved me a *lot* of time.
582 Make sure this information is stored on the tape too so
583 that it can be restored directly from the tape.
585 All the code (with the exception of formally generating and
586 saving the delete file entries) already exists in the Verify
587 Catalog command. It explicitly recognizes added/deleted files since
588 the last InitCatalog. It is more or less a "simple" matter of
589 taking that code and adapting it slightly to work for backups.
591 Comments from Martin Simmons (I think they are all covered):
592 Ok, that should cover the basics. There are few issues though:
594 - Restore will depend on the catalog. I think it is better to include the
595 extra data in the backup as well, so it can be seen by bscan and bextract.
597 - I'm not sure if it will preserve multiple hard links to the same inode. Or
598 maybe adding or removing links will cause the data to be dumped again?
600 - I'm not sure if it will handle renamed directories. Possibly it will work
601 by dumping the whole tree under a renamed directory?
603 - It remains to be seen how the backup performance of the DIR's will be
604 affected when comparing the catalog for a large filesystem.
608 How about introducing a Type = MgmtPolicy job type? That job type would
609 be responsible for scanning the Bacula environment looking for specific
610 conditions, and submitting the appropriate jobs for implementing said
614 Name = "Migration-Policy"
616 Policy Selection Job Type = Migrate
617 Scope = "<keyword> <operator> <regexp>"
618 Threshold = "<keyword> <operator> <regexp>"
619 Job Template = <template-name>
622 Where <keyword> is any legal job keyword, <operator> is a comparison
623 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
624 appropriate regexp. I could see an argument for Scope and Threshold
625 being SQL queries if we want to support full flexibility. The
626 Migration-Policy job would then get scheduled as frequently as a site
627 felt necessary (suggested default: every 15 minutes).
632 Name = "Migration-Policy"
634 Policy Selection Job Type = Migration
636 Threshold = "Migration Selection Type = LowestUtil"
637 Job Template = "MigrationTemplate"
640 would select all pools for examination and generate a job based on
641 MigrationTemplate to automatically select the volume with the lowest
642 usage and migrate it's contents to the nextpool defined for that pool.
644 This policy abstraction would be really handy for adjusting the behavior
645 of Bacula according to site-selectable criteria (one thing that pops
646 into mind is Amanda's ability to automatically adjust backup levels
647 depending on various criteria).
653 - Add Pool/Storage override regression test.
654 - Add delete JobId to regression.
655 - Add a regression test for dbcheck.
656 - New test to add bscan to four-concurrent-jobs regression,
657 i.e. after the four-concurrent jobs zap the
658 database as is done in the bscan-test, then use bscan to
659 restore the database, do a restore and compare with the
661 - Add restore of specific JobId to regression (item 3
662 on the restore prompt)
663 - Add IPv6 to regression
664 - Add database test to regression. Test each function like delete,
667 - AntiVir can slow down backups on Win32 systems.
668 - Win32 systems with FAT32 can be much slower than NTFS for
669 more than 1000 files per directory.
673 - A HOLD command to stop all jobs from starting.
674 - A PAUSE command to pause all running jobs ==> release the
676 - Media Type = LTO,LTO-2,LTO-3
677 Media Type Read = LTO,LTO2,LTO3
678 Media Type Write = LTO2, LTO3
680 === From Carsten Menke <bootsy52@gmx.net>
682 Following is a list of what I think in the situations where I'm faced with,
683 could be a usefull enhancement to bacula, which I'm certain other users will
684 benefit from as well.
686 1. NextJob/NextJobs Directive within a Job Resource in the form of
687 NextJobs = job1,job2.
690 I currently solved the problem with running multiple jobs each after each
691 by setting the Max Wait Time for a job to 8 hours, and give
692 the jobs different Priorities. However, there scenarios where
693 1 Job is directly depending on another job, so if the former job fails,
694 the job after it needn't to be run
695 while maybe other jobs should run despite of that
698 A Backup Job and a Verify job, if the backup job fails there is no need to run
699 the verify job, as the backup job already failed. However, one may like
700 to backup the Catalog to disk despite of that the main backup job failed.
703 I see that this is related to the Event Handlers which are on the ToDo
704 list, also it is maybe a good idea to check for the return value and
705 execute different actions based on the return value
708 3. offline capability to bconsole
711 Currently I use a script which I execute within the last Job via the
712 RunAfterJob Directive, to release and eject the tape.
713 So I have to call bconsole "release=Storage-Name" and afterwards
714 mt -f /dev/nst0 eject to get the tape out.
716 If I have multiple Storage Devices, than these may not be /dev/nst0 and
717 I have to modify the script or call it with parameters etc.
718 This would actually not be needed, as everything is already defined
719 in bacula-sd.conf and if I can invoke bconsole with the
720 storage name via $1 in the script than I'm done and information is
723 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
727 For the reason mentioned in 3. to have the ability to call a
728 script with /scripts/foobar %s and in the script use $1
729 to pass the Storage Name to bconsole
731 5. Setting Volume State within a Job Resource
734 Instead of using "Maximum Volume Jobs" in the Pool Resource,
735 I would have the possibilty to define
736 in a Job Resource that after this certain job is run, the Volume State
737 should be set to "Volume State = Used", this give more flexibility (IMHO).
739 6. Localization of Bacula Messages
742 Unfortunatley many,many people I work with don't speak english very well.
743 So if at least the Reporting messages would be localized then they
744 would understand that they have to change the tape,etc. etc.
746 I volunteer to do the german translations, and if I can convince my wife also
747 french and Morre (western african language).
749 7. OK, this is evil, probably bound to security risks and maybe not possible
750 due to the design of bacula.
752 Implementation of Backtics ( `command` ) for shell comand execution to
753 the "Label Format" Directive.
757 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
758 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
759 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
760 the localized name for the day of the week appended to the
761 format string. Then I have the tape labeled automatically with weekday
762 name in the correct language.
764 - Yes, that is surely the case. I probably should turn those into Warning
765 errors. In addition, you just made me think that it might not be bad to
766 add an option to check the file size after backing up the file and
767 report if it changes. This would be done as an option because it would
770 Kern, good idea. If you do do that, mention in the output: file
771 shrunk, or file expanded, just to make it obvious to the user
772 (without having to the refer to file size), just how the file size
775 Would this option be for all file, or just one file? Or a fileset?
776 - Make output from status use html table tags for nicely
777 presenting in a browser.
778 - Can one write tapes faster with 8192 byte block sizes?
779 - Document security problems with the same password for everyone in
780 rpm and Win32 releases.
781 - Browse generations of files.
782 - I've seen an error when my catalog's File table fills up. I
783 then have to recreate the File table with a larger maximum row
784 size. Relevant information is at
785 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
786 "Installing and Configuring MySQL" chapter should talk a bit
787 about this potential problem, and recommend a solution.
788 - For Solaris must use POSIX awk.
789 - Want speed of writing to tape while despooling.
790 - Supported autochanger:
798 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
799 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
800 - Add regex from http://www.pcre.org to Bacula for Win32.
801 - Use only shell tools no make in CDROM package.
802 - Include within include does it work?
803 - Implement a Pool of type Cleaning?
804 - Implement VolReadTime and VolWriteTime in SD
805 - Modify Backing up Your Database to include a bootstrap file.
806 - Think about making certain database errors fatal.
807 - Look at correcting the time jump in the scheduler for daylight
808 savings time changes.
809 - Add a "real" timer to network connections.
810 - Promote to Full = Time period
811 - Check dates entered by user for correctness (month/day/... ranges)
812 - Compress restore Volume listing by date and first file.
813 - Look at patches/bacula_db.b2z postgresql that loops during restore.
815 - Perhaps add read/write programs and/or plugins to FileSets.
816 - How to handle backing up portables ...
817 - Add some sort of guaranteed Interval for upgrading jobs.
818 - Can we write the state file after every job terminates? On Win32
819 the system crashes and the state file is not updated.
822 Documentation to do: (any release a little bit at a time)
823 - Doc to do unmount before removing magazine.
824 - Alternative to static linking "ldd prog" save all binaries listed,
825 restore them and point LD_LIBRARY_PATH to them.
826 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
827 - Document query file format.
828 - Add more documentation for bsr files.
829 - Document problems with Verify and pruning.
830 - Document how to use multiple databases.
831 - VXA drives have a "cleaning required"
832 indicator, but Exabyte recommends preventive cleaning after every 75
835 In this context, it should be noted that Exabyte has a command-line
836 vxatool utility available for free download. (The current version is
837 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
838 test the drive, unload tapes, change drive settings, flash new firmware,
840 Of particular interest in this context is that vxatool <device> -i will
841 report, among other details, the time since last cleaning in tape motion
842 minutes. This information can be retrieved (and settings changed, for
843 that matter) through the generic-SCSI device even when Bacula has the
844 regular tape device locked. (Needless to say, I don't recommend
845 changing tape settings while a job is running.)
846 - Lookup HP cleaning recommendations.
847 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
848 - Document doing table repair
851 ===================================
852 - Add macro expansions in JobDefs.
853 Run Before Job = "SomeFile %{Level} %{Client}"
854 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
855 - Use non-blocking network I/O but if no data is available, use
857 - Use gather write() for network I/O.
858 - Autorestart on crash.
859 - Add bandwidth limiting.
860 - Add acks every once and a while from the SD to keep
861 the line from timing out.
862 - When an error in input occurs and conio beeps, you can back
863 up through the prompt.
864 - Detect fixed tape block mode during positioning by looking at
865 block numbers in btape "test". Possibly adjust in Bacula.
866 - Fix list volumes to output volume retention in some other
867 units, perhaps via a directive.
868 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
869 with multiple priorities.
870 - If you use restore replace=never, the directory attributes for
871 non-existent directories will not be restored properly.
873 - see lzma401.zip in others directory for new compression
875 - Allow the user to select JobType for manual pruning/purging.
876 - bscan does not put first of two volumes back with all info in
878 - Implement the FreeBSD nodump flag in chflags.
879 - Figure out how to make named console messages go only to that
880 console and to the non-restricted console (new console class?).
881 - Make restricted console prompt for password if *ask* is set or
882 perhaps if password is undefined.
883 - Implement "from ISO-date/time every x hours/days/weeks/months" in
886 ==== from Marc Schoechlin
887 - the help-command should be more verbose
888 (it should explain the paramters of the different
890 -> its time-comsuming to consult the manual anytime
891 you need a special parameter
892 -> maybe its more easy to maintain this, if the
893 descriptions of that commands are outsourced to
895 - the cd-command should allow complete paths
896 i.e. cd /foo/bar/foo/bar
897 -> if a customer mails me the path to a certain file,
898 its faster to enter the specified directory
899 - if the password is not configured in bconsole.conf
900 you should be asked for it.
901 -> sometimes you like to do restore on a customer-machine
902 which shouldnt know the password for bacula.
903 -> adding the password to the file favours admins
904 to forget to remove the password after usage
906 the protection of that file is less important
907 - long-listed-output of commands should be scrollable
908 like the unix more/less-command does
909 -> if someone runs 200 and more machines, the lists could
910 be a little long and complex
911 - command-output should be shown column by column
912 to reduce scrolling and to increase clarity
914 - lsmark should list the selected files with full
916 - wildcards for selecting and file and directories would be nice
917 - any actions should be interuptable with STRG+C
918 - command-expansion would be pretty cool
920 - When the replace Never option is set, new directory permissions
921 are not restored. See bug 213. To fix this requires creating a
922 list of newly restored directories so that those directory
923 permissions *can* be restored.
924 - Add prune all command
925 - Document fact that purge can destroy a part of a restore by purging
926 one volume while others remain valid -- perhaps mark Jobs.
927 - Add multiple-media-types.txt
928 - look at mxt-changer.html
929 - Make ? do a help command (no return needed).
930 - Implement restore directory.
931 - Document streams and how to implement them.
932 - Try not to re-backup a file if a new hard link is added.
933 - Add feature to backup hard links only, but not the data.
934 - Fix stream handling to be simpler.
935 - Add Priority and Bootstrap to Run a Job.
936 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
938 - Remove View FileSet button from Run a Job dialog.
939 - Handle prompt for restore job at end of Restore command.
940 - Add display of total selected files to Restore window.
941 - Add tree pane to left of window.
942 - Add progress meter.
943 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
944 - Add message to user to check for fixed block size when the forward
945 space test fails in btape.
946 - When unmarking a directory check if all files below are unmarked and
947 then remove the + flag -- in the restore tree.
948 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
949 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
950 - Revisit the question of multiple Volumes (disk) on a single device.
951 - Add a block copy option to bcopy.
952 - Finish work on Gnome restore GUI.
953 - Fix "llist jobid=xx" where no fileset or client exists.
954 - For each job type (Admin, Restore, ...) require only the really necessary
955 fields.- Pass Director resource name as an option to the Console.
956 - Add a "batch" mode to the Console (no unsolicited queries, ...).
957 - Add a .list all files in the restore tree (probably also a list all files)
958 Do both a long and short form.
959 - Allow browsing the catalog to see all versions of a file (with
960 stat data on each file).
961 - Restore attributes of directory if replace=never set but directory
963 - Use SHA1 on authentication if possible.
964 - See comtest-xxx.zip for Windows code to talk to USB.
965 - Add John's appended files:
966 Appended = { /files/server/logs/http/*log }
967 and such files would be treated as follows.On a FULL backup, they would
968 be backed up like any other file.On an INCREMENTAL backup, where a
969 previous INCREMENTAL or FULL was already in thecatalogue and the length
970 of the file wasgreater than the length of the last backup, only thedata
971 added since the last backup will be dumped.On an INCREMENTAL backup, if
972 the length of the file is less than thelength of the file with the same
973 name last backed up, the completefile is dumped.On Windows systems, with
974 creation date of files, we can be evensmarter about this and not count
975 entirely upon the length.On a restore, the full and all incrementals
976 since it will beapplied in sequence to restore the file.
977 - Check new HAVE_WIN32 open bits.
978 - Check if the tape has moved before writing.
979 - Handling removable disks -- see below:
980 - Keep track of tape use time, and report when cleaning is necessary.
981 - Add FromClient and ToClient keywords on restore command (or
982 BackupClient RestoreClient).
983 - Implement a JobSet, which groups any number of jobs. If the
984 JobSet is started, all the jobs are started together.
985 Allow Pool, Level, and Schedule overrides.
986 - Enhance cancel to timeout BSOCK packets after a specific delay.
987 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
988 ua_status.!!! Thanks to Alan Brown for this tip.
989 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
990 correctly for multiple simultaneous jobs.
991 - Correct code so that FileSet MD5 is calculated for < and | filename
993 - Implement the Media record flag that indicates that the Volume does disk
995 - Implement VolAddr, which is used when Volume is addressed like a disk,
996 and form it from VolFile and VolBlock.
997 - Make multiple restore jobs for multiple media types specifying
998 the proper storage type.
999 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1000 pointer (rec) to try_repositioning().
1001 - Look at extracting Win data from BackupRead.
1002 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1003 which would take precidence over the Catalog "JobRetention".
1004 - Implement Label Format in Add and Label console commands.
1005 - Possibly up network buffers to 65K. Put on variable.
1006 - Put email tape request delays on one or more variables. User wants
1007 to cancel the job after a certain time interval. Maximum Mount Wait?
1008 - Job, Client, Device, Pool, or Volume?
1009 Is it possible to make this a directive which is *optional* in multiple
1010 resources, like Level? If so, I think I'd make it an optional directive
1011 in Job, Client, and Pool, with precedence such that Job overrides Client
1012 which in turn overrides Pool.
1014 - New Storage specifications:
1015 - Want to write to multiple storage devices simultaneously
1016 - Want to write to multiple storage devices sequentially (in one job)
1017 - Want to read/write simultaneously
1018 - Key is MediaType -- it must match
1020 Passed to SD as a sort of BSR record called Storage Specification
1024 MediaType -> Next MediaType
1026 Device -> Next Device
1028 Allow multiple Storage specifications
1036 Allow Multiple Pool specifications (note, Pool currently
1038 Allow Multiple MediaType specifications in Dir conf
1039 Allow Multiple Device specifications in Dir conf
1040 Perhaps keep this in a single SSR
1041 Tie a Volume to a specific device by using a MediaType that
1042 is contained in only one device.
1043 In SD allow Device to have Multiple MediaTypes
1045 - Ideas from Jerry Scharf:
1046 First let's point out some big pluses that bacula has for this
1048 more importantly it's active. Thank you so much for that
1049 even more important, it's not flaky
1050 it has an open access catalog, opening many possibilities
1051 it's pushing toward heterogeneous systems capability
1053 Macintosh file client
1054 macs are an interesting niche, but I fear a server is a rathole
1055 working bare iron recovery for windows
1056 the option for inc/diff backups not reset on fileset revision
1057 a) use both change and inode update time against base time
1058 b) do the full catalog check (expensive but accurate)
1059 sizing guide (how much system is needed to back up N systems/files)
1060 consultants on using bacula in building a disaster recovery system
1061 an integration guide
1062 or how to get at fancy things that one could do with bacula
1063 logwatch code for bacula logs (or similar)
1064 linux distro inclusion of bacula (brings good and bad, but necessary)
1065 win2k/XP server capability (icky but you asked)
1066 support for Oracle database ??
1068 - Look at adding SQL server and Exchange support for Windows.
1069 - Make dev->file and dev->block_num signed integers so that -1 can
1070 be an invalid value which happens with BSR.
1071 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1072 is needed to properly specify ranges.
1073 - Add progress of files/bytes to SD and FD.
1074 - Print warning message if FileId > 4 billion
1075 - do a "messages" before the first prompt in Console
1076 - Client does not show busy during Estimate command.
1077 - Implement Console mtx commands.
1078 - Implement a Mount Command and an Unmount Command where
1079 the users could specify a system command to be performed
1080 to do the mount, after which Bacula could attempt to
1081 read the device. This is for Removeable media such as a CDROM.
1082 - Most likely, this mount command would be invoked explicitly
1083 by the user using the current Console "mount" and "unmount"
1084 commands -- the Storage Daemon would do the right thing
1085 depending on the exact nature of the device.
1086 - As with tape drives, when Bacula wanted a new removable
1087 disk mounted, it would unmount the old one, and send a message
1088 to the user, who would then use "mount" as described above
1089 once he had actually inserted the disk.
1090 - Implement dump/print label to UA
1091 - Spool to disk only when the tape is full, then when a tape is hung move
1093 - bextract is sending everything to the log file ****FIXME****
1094 - Allow multiple Storage specifications (or multiple names on
1095 a single Storage specification) in the Job record. Thus a job
1096 can be backed up to a number of storage devices.
1097 - Implement some way for the File daemon to contact the Director
1098 to start a job or pass its DHCP obtained IP number.
1099 - Implement a query tape prompt/replace feature for a console
1100 - Copy console @ code to gnome2-console
1101 - Make tree walk routines like cd, ls, ... more user friendly
1102 by handling spaces better.
1103 - Make sure that Bacula rechecks the tape after the 20 min wait.
1104 - Set IO_NOWAIT on Bacula TCP/IP packets.
1105 - Try doing a raw partition backup and restore by mounting a
1107 - From Lars Kellers:
1108 Yes, it would allow to highly automatic the request for new tapes. If a
1109 tape is empty, bacula reads the barcodes (native or simulated), and if
1110 an unused tape is found, it runs the label command with all the
1111 necessary parameters.
1113 By the way can bacula automatically "move" an empty/purged volume say
1114 in the "short" pool to the "long" pool if this pool runs out of volume
1116 - What to do about "list files job=xxx".
1117 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1118 file descriptor leak in Bacula.
1119 - Implement WrapCounters in Counters.
1120 - Add heartbeat from FD to SD if hb interval expires.
1121 - Can we dynamically change FileSets?
1122 - If pool specified to label command and Label Format is specified,
1123 automatically generate the Volume name.
1124 - Why can't SQL do the filename sort for restore?
1125 - Add ExhautiveRestoreSearch
1126 - Look at the possibility of loading only the necessary
1127 data into the restore tree (i.e. do it one directory at a
1128 time as the user walks through the tree).
1129 - Possibly use the hash code if the user selects all for a restore command.
1130 - Fix "restore all" to bypass building the tree.
1131 - Prohibit backing up archive device (findlib/find_one.c:128)
1132 - Implement Release Device in the Job resource to unmount a drive.
1133 - Implement Acquire Device in the Job resource to mount a drive,
1134 be sure this works with admin jobs so that the user can get
1135 prompted to insert the correct tape. Possibly some way to say to
1136 run the job but don't save the files.
1137 - Make things like list where a file is saved case independent for
1139 - Use autochanger to handle multiple devices.
1140 - Implement a Recycle command
1141 - Start working on Base jobs.
1142 - Implement UnsavedFiles DB record.
1143 - From Phil Stracchino:
1144 It would probably be a per-client option, and would be called
1145 something like, say, "Automatically purge obsoleted jobs". What it
1146 would do is, when you successfully complete a Differential backup of a
1147 client, it would automatically purge all Incremental backups for that
1148 client that are rendered redundant by that Differential. Likewise,
1149 when a Full backup on a client completed, it would automatically purge
1150 all Differential and Incremental jobs obsoleted by that Full backup.
1151 This would let people minimize the number of tapes they're keeping on
1152 hand without having to master the art of retention times.
1153 - When doing a Backup send all attributes back to the Director, who
1154 would then figure out what files have been deleted.
1155 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1156 explicit permission to do so. It should also mark the tape in error
1157 if there is an error.
1158 - Cancel waiting for Client connect in SD if FD goes away.
1160 - Implement timeout in response() when it should come quickly.
1161 - Implement a Slot priority (loaded/not loaded).
1162 - Implement "vacation" Incremental only saves.
1163 - Implement create "FileSet"?
1164 - Add prefixlinks to where or not where absolute links to FD.
1165 - Issue message to mount a new tape before the rewind.
1166 - Simplified client job initiation for portables.
1167 - If SD cannot open a drive, make it periodically retry.
1168 - Add more of the config info to the tape label.
1170 - Refine SD waiting output:
1171 Device is being positioned
1172 > Device is being positioned for append

1175 - Figure out some way to estimate output size and to avoid splitting
1176 a backup across two Volumes -- this could be useful for writing CDROMs
1177 where you really prefer not to have it split -- not serious.
1178 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1179 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1180 actual data on the Volume and compare it.
1181 - Implement Bacula plugins -- design API
1182 - Make bcopy read through bad tape records.
1183 - Program files (i.e. execute a program to read/write files).
1184 Pass read date of last backup, size of file last time.

1194 - Add code to reject whole blocks if not wanted on restore.
1195 - Check if we can increase Bacula FD priorty in Win2000
1196 - Make sure the MaxVolFiles is fully implemented in SD

1221 - Implement script driven addition of File daemon to config files.
1222 - Think about how to make Bacula work better with File (non-tape) archives.
1223 - Write Unix emulator for Windows.
1224 - Put memory utilization in Status output of each daemon
1225 if full status requested or if some level of debug on.

1290 report resource where report=group of messages
1291 - enhance scan_attrib and rename scan_jobtype, and
1292 fill in code for "since" option
1293 - Director needs a time after which the report status is sent
1294 anyway -- or better yet, a retry time for the job.
1295 - Don't reschedule a job if previous incarnation is still running.
1296 - Some way to automatically backup everything is needed????
1297 - Need a structure for pending actions:
1299 - termination status (part of buffered msgs?)
1301 Read, Write, Clean, Delete
1302 - Login to Bacula; Bacula users with different permissions:
1303 owner, group, user, quotas
1304 - Store info on each file system type (probably in the job header on tape.
1305 This could be the output of df; or perhaps some sort of /etc/mtab record.

1308 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1309 To: <kern@sibbald.com>
1310 Subject: RE: [Bacula-users] future large programming jobs
1311 Date: Thu, 26 Feb 2004 11:34:54 -0600
1313 I noticed the subject thread and thought I would offer the following
1314 merely as sources of ideas, i.e. something to think about, not even as
1315 strong as a request. In my former life (before retiring) I often
1316 dealt with backups and storage management issues/products as a
1317 developer and as a consultant. I am currently migrating my personal
1318 network from amanda to bacula specifically because of the ability to
1319 cross media boundaries during storing backups.
1320 Are you familiar with the commercial product called ADSM (I think IBM
1321 now sells it under the Tivoli label)? It has a couple of interesting
1322 ideas that may apply to the following topics.
1324 1. Migration: Consider that when you need to restore a system, there
1325 may be pressure to hurry. If all the information for a single client
1326 can eventually end up on the same media (and in chronological order),
1327 the restore is facillitated by not having to search past information
1328 from other clients. ADSM has the concept of "client affinity" that
1329 may be associated with it's storage pools. It seems to me that this
1330 concept (as an optional feature) might fit in your architecture for
1333 ADSM also has the concept of defining one or more storage pools as
1334 "copy pools" (almost mirrors, but only in the sense of contents).
1335 These pools provide the ability to have duplicte data stored both
1336 onsite and offsite. The copy process can be scheduled to be handled
1337 by their storage manager during periods when there is no backup
1338 activity. Again, the migration process might be a place to consider
1339 implementing something like this.
1342 > It strikes me that it would be very nice to be able to do things
1344 > have the Job(s) backing up the machines run, and once they have all

1350 > mechanism described below would probably make it very easy.
1352 This is the goal. In the first step (before events), you simply
1354 the Migration to tape later.
1356 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1357 the database. Once a file (unique by path and metadata such as dates,
1358 size, ownership, etc.) is in a copy pool, no more copies are made. In
1359 other words, when you start ADSM, it begins like your concept of a
1360 base job. After that it is in the "incremental" mode. You can
1361 configure the number of "generations" of files to be retained, plus a
1362 retention date after which even old generations are purged. The
1363 database tracks the contents of media and projects the percentage of
1364 each volume that is valid. When the valid content of a volume drops
1365 below a configured percentage, the valid data are migrated to another
1366 volume and the old volume is marked as empty. Note, this requires
1367 ADSM to have an idea of the contents of a client, i.e. marking the
1368 database when an existing file was deleted, but this would solve your
1369 issue of restoring a client without restoring deleted files.
1371 This is pretty far from what bacula now does, but if you are going to
1372 rip things up for Base jobs,.....
1373 Also, the benefits of this are huge for very large shops, especially
1374 with media robots, but are a pain for shops with manual media
1378 > Base jobs sound pretty useful, but I'm not dying for them.
1380 Nobody is dying for them, but when you see what it does, you will die
1383 3. Restoring deleted files: Since I think my comments in (2) above
1384 have low probability of implementation, I'll also suggest that you
1385 could approach the issue of deleted files by a mechanism of having the
1386 fd report to the dir, a list of all files on the client for every
1387 backup job. The dir could note in the database entry for each file
1388 the date that the file was seen. Then if a restore as of date X takes
1389 place, only files that exist from before X until after X would be
1390 restored. Probably the major cost here is the extra date container in
1391 each row of the files table.
1393 Thanks for "listening". I hope some of this helps. If you want to
1394 contact me, please send me an email - I read some but not all of the
1395 mailing list traffic and might miss a reply there.
1397 Please accept my compliments for bacula. It is doing a great job for
1398 me!! I sympathize with you in the need to wrestle with excelence in
1399 execution vs. excelence in feature inclusion.
1404 ==============================
1407 - Design at hierarchial storage for Bacula. Migration and Clone.
1408 - Implement FSM (File System Modules).
1409 - Audit M_ error codes to ensure they are correct and consistent.
1410 - Add variable break characters to lex analyzer.
1411 Either a bit mask or a string of chars so that
1412 the caller can change the break characters.
1413 - Make a single T_BREAK to replace T_COMMA, etc.
1414 - Ensure that File daemon and Storage daemon can
1415 continue a save if the Director goes down (this
1416 is NOT currently the case). Must detect socket error,
1417 buffer messages for later.
1418 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1419 - Add ability to backup to two Storage devices (two SD sessions) at
1420 the same time -- e.g. onsite, offsite.
1421 - Add the ability to consolidate old backup sets (basically do a restore
1422 to tape and appropriately update the catalog). Compress Volume sets.
1423 Might need to spool via file is only one drive is available.
1424 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1425 someway to do so with every volume that has less than x% valid
1429 Migration: Move a backup from one Volume to another
1430 Clone: Copy a backup -- two Volumes
1433 ======================================================
1435 It is somewhat like a Full save becomes an incremental since
1436 the Base job (or jobs) plus other non-base files.
1438 - A Base backup is same as Full backup, just different type.
1439 - New BaseFiles table that contains:
1441 BaseJobId - Base JobId referenced for this FileId (needed ???)
1442 JobId - JobId currently running
1443 FileId - File not backed up, exists in Base Job
1444 FileIndex - FileIndex from Base Job.
1445 i.e. for each base file that exists but is not saved because
1446 it has not changed, the File daemon sends the JobId, BaseId,
1447 FileId, FileIndex back to the Director who creates the DB entry.
1448 - To initiate a Base save, the Director sends the FD
1449 the FileId, and full filename for each file in the Base.
1450 - When the FD finds a Base file, he requests the Director to
1451 send him the full File entry (stat packet plus MD5), or
1452 conversely, the FD sends it to the Director and the Director
1453 says yes or no. This can be quite rapid if the FileId is kept
1454 by the FD for each Base Filename.
1455 - It is probably better to have the comparison done by the FD
1456 despite the fact that the File entry must be sent across the
1458 - An alternative would be to send the FD the whole File entry
1459 from the start. The disadvantage is that it requires a lot of
1460 space. The advantage is that it requires less communications
1462 - The Job record must be updated to indicate that one or more
1464 - At end of Job, FD returns:
1465 1. Count of base files/bytes not written to tape (i.e. matches)
1466 2. Count of base file that were saved i.e. had changed.
1467 - No tape record would be written for a Base file that matches, in the
1468 same way that no tape record is written for Incremental jobs where
1469 the file is not saved because it is unchanged.
1470 - On a restore, all the Base file records must explicitly be
1471 found from the BaseFile tape. I.e. for each Full save that is marked
1472 to have one or more Base Jobs, search the BaseFile for all occurrences
1474 - An optimization might be to make the BaseFile have:
1480 This would avoid the need to explicitly fetch each File record for
1481 the Base job. The Base Job record will be fetched to get the
1482 VolSessionId and VolSessionTime.
1483 =========================================================
1486 ==========================================================
1488 For each Incremental job that is run, there may be files that
1489 were found but not saved because they were locked (this applies
1490 only to Windows). Such a system could send back to the Director
1491 a list of Unsaved files.
1493 - New UnSavedFiles table that contains:
1497 - Then in the next Incremental job, the list of Unsaved Files will be
1498 feed to the FD, who will ensure that they are explicitly chosen even
1499 if standard date/time check would not have selected them.

1541 (just to verify it remembers where it came from, however it can be
1542 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1544 There needs to be a table of drive # to devices somewhere - If there are
1545 multiple changers or drives there may not be a 1:1 correspondance between
1546 changer drive number and system device name - and depending on the way the
1547 drives are hooked up to scsi busses, they may not be linearly numbered
1548 from an offset point either.something like
1550 Autochanger drives = 2
1551 Autochanger drive 0 = /dev/nst1
1552 Autochanger drive 1 = /dev/nst2
1553 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1554 times, not just for multidrive changers. For a 1 drive changer, that's
1560 MTX's manpage (1.2.15):
1561 unload [<slotnum>] [ <drivenum> ]
1562 Unloads media from drive <drivenum> into slot
1563 <slotnum>. If <drivenum> is omitted, defaults to
1564 drive 0 (as do all commands). If <slotnum> is
1565 omitted, defaults to the slot that the drive was
1566 loaded from. Note that there's currently no way
1567 to say 'unload drive 1's media to the slot it
1568 came from', other than to explicitly use that
1569 slot number as the destination.AB

1607 Handling removable disks
1609 From: Karl Cunningham <karlc@keckec.com>
1611 My backups are only to hard disk these days, in removable bays. This is my
1612 idea of how a backup to hard disk would work more smoothly. Some of these
1613 things Bacula does already, but I mention them for completeness. If others
1614 have better ways to do this, I'd like to hear about it.
1616 1. Accommodate several disks, rotated similar to how tapes are. Identified
1617 by partition volume ID or perhaps by the name of a subdirectory.
1618 2. Abort & notify the admin if the wrong disk is in the bay.
1619 3. Write backups to different subdirectories for each machine to be backed
1621 4. Volumes (files) get created as needed in the proper subdirectory, one
1623 5. When a disk is recycled, remove or zero all old backup files. This is
1624 important as the disk being recycled may be close to full. This may be
1625 better done manually since the backup files for many machines may be
1626 scattered in many subdirectories.
1631 - Make sure that all do_prompt() calls in Dir check for
1632 -1 (error) and -2 (cancel) returns.
1633 - Fix foreach_jcr() to have free_jcr() inside next().
1634 jcr=jcr_walk_start();
1635 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1638 - A Volume taken from Scratch should take on the retention period
1640 - Correct doc for Maximum Changer Wait (and others) accepting only
1642 - Implement status that shows why a job is being held in reserve, or
1643 rather why none of the drives are suitable.
1644 - Implement a way to disable a drive (so you can use the second
1645 drive of an autochanger, and the first one will not be used or
1647 - Make sure Maximum Volumes is respected in Pools when adding
1648 Volumes (e.g. when pulling a Scratch volume).
1649 - Keep same dcr when switching device ...
1650 - Implement code that makes the Dir aware that a drive is an
1651 autochanger (so the user doesn't need to use the Autochanger = yes
1653 - Make catalog respect ACL.
1654 - Add recycle count to Media record.
1655 - Add initial write date to Media record.
1656 - Fix store_yesno to be store_bitmask.
