14 - During tests with the 260 char fix code, I found one problem:
15 if the system "sees" a long path once, it seems to forget it's
16 working drive (e.g. c:\), which will lead to a problem during
17 the next job (create bootstrap file will fail). Here is the
18 workaround: specify absolute working and pid directory in
19 bacula-fd.conf (e.g. c:\bacula\working instead of

67 - Ensure that each device in an Autochanger has a different
69 - Add Catalog = to Pool resource so that pools will exist
70 in only one catalog -- currently Pools are "global".
71 - Look at sg_logs -a /dev/sg0 for getting soft errors.

173 better machine-readable output like "Ok" or "Error busy"
174 .move eject device=xxx toslot=yyy the same as above, but with a new

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

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

444 - Add VolumeLock to prevent all but lock holder (SD) from updating
445 the Volume data (with the exception of VolumeState).
446 - The btape fill command does not seem to use the Autochanger
447 - Make Windows installer default to system disk drive.
448 - Look at using ioctl(FIOBMAP, ...) on Linux, and

468 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
469 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
470 - Implement a mode that says when a hard read error is
471 encountered, read many times (as it currently does), and if the
472 block cannot be read, skip to the next block, and try again. If
473 that fails, skip to the next file and try again, ...
475 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
476 insert into LevelType (LevelType,LevelTypeLong) values
480 - Show files/second in client status output.
481 - Add a recursive mark command (rmark) to restore.
482 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
483 of the same level and does not permit multiple simultaneous
484 running of that Job (i.e. lets any previous invocation finish
485 before doing Interval testing).
486 - Look at simplifying File exclusions.
487 - New directive "Delete purged Volumes"
488 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
489 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
490 see if it become stable and I just have to supervise
492 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
493 PoolId, and when it is empty remove it.
494 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
496 - Allow Check Labels to be used with Bacula labels.
497 - "Resuming" a failed backup (lost line for example) by using the
498 failed backup as a sort of "base" job.
500 - Email to the user when the tape is about to need changing x
501 days before it needs changing.
502 - Command to show next tape that will be used for a job even
503 if the job is not scheduled.
504 - From: Arunav Mandal <amandal@trolltech.com>
505 1. When jobs are running and bacula for some reason crashes or if I do a
506 restart it remembers and jobs it was running before it crashed or restarted
507 as of now I loose all jobs if I restart it.
509 2. When spooling and in the midway if client is disconnected for instance a
510 laptop bacula completely discard the spool. It will be nice if it can write
511 that spool to tape so there will be some backups for that client if not all.
513 3. We have around 150 clients machines it will be nice to have a option to
514 upgrade all the client machines bacula version automatically.
516 4. Atleast one connection should be reserved for the bconsole so at heavy load
517 I should connect to the director via bconsole which at sometimes I can't
519 5. Another most important feature that is missing, say at 10am I manually
520 started backup of client abc and it was a full backup since client abc has
521 no backup history and at 10.30am bacula again automatically started backup of
522 client abc as that was in the schedule. So now we have 2 multiple Full
523 backups of the same client and if we again try to start a full backup of
524 client backup abc bacula won't complain. That should be fixed.
526 - Fix bpipe.c so that it does not modify results pointer.
527 ***FIXME*** calling sequence should be changed.
528 - For Windows disaster recovery see http://unattended.sf.net/
529 - regardless of the retention period, Bacula will not prune the
530 last Full, Diff, or Inc File data until a month after the
531 retention period for the last Full backup that was done.
532 - update volume=xxx --- add status=Full
533 - Remove old spool files on startup.
534 - Exclude SD spool/working directory.
535 - Refuse to prune last valid Full backup. Same goes for Catalog.
537 - Make a callback when Rerun failed levels is called.
538 - Give Python program access to Scheduled jobs.
539 - Add setting Volume State via Python.
540 - Python script to save with Python, not save, save with Bacula.
541 - Python script to do backup.
543 - Change the Priority, Client, Storage, JobStatus (error)
544 at the start of a job.
545 - Why is SpoolDirectory = /home/bacula/spool; not reported
546 as an error when writing a DVD?
547 - Make bootstrap file handle multiple MediaTypes (SD)
548 - Remove all old Device resource code in Dir and code to pass it
549 back in SD -- better, rework it to pass back device statistics.
550 - Check locking of resources -- be sure to lock devices where previously
551 resources were locked.
552 - The last part is left in the spool dir.
555 - In restore don't compare byte count on a raw device -- directory
556 entry does not contain bytes.
560 MA = (last_MA * 3 + rate) / 4
561 rate = (bytes - last_bytes) / (runtime - last_runtime)
562 - Max Vols limit in Pool off by one?
563 - Implement Files/Bytes,... stats for restore job.
564 - Implement Total Bytes Written, ... for restore job.
565 - Despool attributes simultaneously with data in a separate
566 thread, rejoined at end of data spooling.
567 - 7. Implement new Console commands to allow offlining/reserving drives,
568 and possibly manipulating the autochanger (much asked for).
569 - Add start/end date editing in messages (%t %T, %e?) ...
570 - Add ClientDefs similar to JobDefs.
571 - Print more info when bextract -p accepts a bad block.
572 - Fix FD JobType to be set before RunBeforeJob in FD.
573 - Look at adding full Volume and Pool information to a Volume
574 label so that bscan can get *all* the info.
575 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
576 and there is only one volume in the pool, refuse to do it -- otherwise
577 he fills the Volume, then immediately starts reusing it.
578 - Implement copies and stripes.
579 - Add history file to console.
580 - Each file on tape creates a JobMedia record. Peter has 4 million
581 files spread over 10000 tape files and four tapes. A restore takes
582 16 hours to build the restore list.
583 - Add and option to check if the file size changed during backup.
584 - Make sure SD deletes spool files on error exit.
585 - Delete old spool files when SD starts.
586 - When labeling tapes, if you enter 000026, Bacula uses
587 the tape index rather than the Volume name 000026.
588 - Add offline tape command to Bacula console.
590 Enter MediaId or Volume name: 32
591 Enter new Volume name: DLT-20Dec04

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

750 === From Carsten Menke <bootsy52@gmx.net>
752 Following is a list of what I think in the situations where I'm faced with,
753 could be a usefull enhancement to bacula, which I'm certain other users will
754 benefit from as well.
756 1. NextJob/NextJobs Directive within a Job Resource in the form of
757 NextJobs = job1,job2.
760 I currently solved the problem with running multiple jobs each after each
761 by setting the Max Wait Time for a job to 8 hours, and give
762 the jobs different Priorities. However, there scenarios where
763 1 Job is directly depending on another job, so if the former job fails,
764 the job after it needn't to be run
765 while maybe other jobs should run despite of that
768 A Backup Job and a Verify job, if the backup job fails there is no need to run
769 the verify job, as the backup job already failed. However, one may like
770 to backup the Catalog to disk despite of that the main backup job failed.
773 I see that this is related to the Event Handlers which are on the ToDo
774 list, also it is maybe a good idea to check for the return value and
775 execute different actions based on the return value
778 3. offline capability to bconsole
781 Currently I use a script which I execute within the last Job via the
782 RunAfterJob Directive, to release and eject the tape.
783 So I have to call bconsole "release=Storage-Name" and afterwards
784 mt -f /dev/nst0 eject to get the tape out.
786 If I have multiple Storage Devices, than these may not be /dev/nst0 and
787 I have to modify the script or call it with parameters etc.
788 This would actually not be needed, as everything is already defined
789 in bacula-sd.conf and if I can invoke bconsole with the
790 storage name via $1 in the script than I'm done and information is
793 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
797 For the reason mentioned in 3. to have the ability to call a
798 script with /scripts/foobar %s and in the script use $1
799 to pass the Storage Name to bconsole
801 5. Setting Volume State within a Job Resource
804 Instead of using "Maximum Volume Jobs" in the Pool Resource,
805 I would have the possibilty to define
806 in a Job Resource that after this certain job is run, the Volume State
807 should be set to "Volume State = Used", this give more flexibility (IMHO).
809 6. Localization of Bacula Messages
812 Unfortunatley many,many people I work with don't speak english very well.
813 So if at least the Reporting messages would be localized then they
814 would understand that they have to change the tape,etc. etc.
816 I volunteer to do the german translations, and if I can convince my wife also
817 french and Morre (western african language).
819 7. OK, this is evil, probably bound to security risks and maybe not possible
820 due to the design of bacula.
822 Implementation of Backtics ( `command` ) for shell comand execution to
823 the "Label Format" Directive.
827 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
828 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
829 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
830 the localized name for the day of the week appended to the
831 format string. Then I have the tape labeled automatically with weekday
832 name in the correct language.
834 - Yes, that is surely the case. I probably should turn those into Warning
835 errors. In addition, you just made me think that it might not be bad to
836 add an option to check the file size after backing up the file and
837 report if it changes. This would be done as an option because it would
840 Kern, good idea. If you do do that, mention in the output: file
841 shrunk, or file expanded, just to make it obvious to the user
842 (without having to the refer to file size), just how the file size
845 Would this option be for all file, or just one file? Or a fileset?
846 - Make output from status use html table tags for nicely
847 presenting in a browser.
848 - Can one write tapes faster with 8192 byte block sizes?
849 - Document security problems with the same password for everyone in
850 rpm and Win32 releases.
851 - Browse generations of files.
852 - I've seen an error when my catalog's File table fills up. I
853 then have to recreate the File table with a larger maximum row
854 size. Relevant information is at
855 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
856 "Installing and Configuring MySQL" chapter should talk a bit
857 about this potential problem, and recommend a solution.
858 - For Solaris must use POSIX awk.
859 - Want speed of writing to tape while despooling.
860 - Supported autochanger:
868 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
869 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
870 - Add regex from http://www.pcre.org to Bacula for Win32.
871 - Use only shell tools no make in CDROM package.
872 - Include within include does it work?
873 - Implement a Pool of type Cleaning?
874 - Implement VolReadTime and VolWriteTime in SD
875 - Modify Backing up Your Database to include a bootstrap file.
876 - Think about making certain database errors fatal.
877 - Look at correcting the time jump in the scheduler for daylight
878 savings time changes.
879 - Add a "real" timer to network connections.
880 - Promote to Full = Time period
881 - Check dates entered by user for correctness (month/day/... ranges)
882 - Compress restore Volume listing by date and first file.
883 - Look at patches/bacula_db.b2z postgresql that loops during restore.
885 - Perhaps add read/write programs and/or plugins to FileSets.
886 - How to handle backing up portables ...
887 - Add some sort of guaranteed Interval for upgrading jobs.
888 - Can we write the state file after every job terminates? On Win32
889 the system crashes and the state file is not updated.
892 Documentation to do: (any release a little bit at a time)
893 - Doc to do unmount before removing magazine.
894 - Alternative to static linking "ldd prog" save all binaries listed,
895 restore them and point LD_LIBRARY_PATH to them.
896 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
897 - Document query file format.
898 - Add more documentation for bsr files.
899 - Document problems with Verify and pruning.
900 - Document how to use multiple databases.
901 - VXA drives have a "cleaning required"
902 indicator, but Exabyte recommends preventive cleaning after every 75
905 In this context, it should be noted that Exabyte has a command-line
906 vxatool utility available for free download. (The current version is
907 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
908 test the drive, unload tapes, change drive settings, flash new firmware,
910 Of particular interest in this context is that vxatool <device> -i will
911 report, among other details, the time since last cleaning in tape motion
912 minutes. This information can be retrieved (and settings changed, for
913 that matter) through the generic-SCSI device even when Bacula has the
914 regular tape device locked. (Needless to say, I don't recommend
915 changing tape settings while a job is running.)
916 - Lookup HP cleaning recommendations.
917 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
918 - Document doing table repair
921 ===================================
922 - Add macro expansions in JobDefs.
923 Run Before Job = "SomeFile %{Level} %{Client}"
924 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
925 - Use non-blocking network I/O but if no data is available, use
927 - Use gather write() for network I/O.
928 - Autorestart on crash.
929 - Add bandwidth limiting.
930 - Add acks every once and a while from the SD to keep
931 the line from timing out.
932 - When an error in input occurs and conio beeps, you can back
933 up through the prompt.
934 - Detect fixed tape block mode during positioning by looking at
935 block numbers in btape "test". Possibly adjust in Bacula.
936 - Fix list volumes to output volume retention in some other
937 units, perhaps via a directive.
938 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
939 with multiple priorities.
940 - If you use restore replace=never, the directory attributes for
941 non-existent directories will not be restored properly.
943 - see lzma401.zip in others directory for new compression
945 - Allow the user to select JobType for manual pruning/purging.
946 - bscan does not put first of two volumes back with all info in
948 - Implement the FreeBSD nodump flag in chflags.
949 - Figure out how to make named console messages go only to that
950 console and to the non-restricted console (new console class?).
951 - Make restricted console prompt for password if *ask* is set or
952 perhaps if password is undefined.
953 - Implement "from ISO-date/time every x hours/days/weeks/months" in
956 ==== from Marc Schoechlin
957 - the help-command should be more verbose
958 (it should explain the paramters of the different
960 -> its time-comsuming to consult the manual anytime
961 you need a special parameter
962 -> maybe its more easy to maintain this, if the
963 descriptions of that commands are outsourced to
965 - the cd-command should allow complete paths
966 i.e. cd /foo/bar/foo/bar
967 -> if a customer mails me the path to a certain file,
968 its faster to enter the specified directory
969 - if the password is not configured in bconsole.conf
970 you should be asked for it.
971 -> sometimes you like to do restore on a customer-machine
972 which shouldnt know the password for bacula.
973 -> adding the password to the file favours admins
974 to forget to remove the password after usage
976 the protection of that file is less important
977 - long-listed-output of commands should be scrollable
978 like the unix more/less-command does
979 -> if someone runs 200 and more machines, the lists could
980 be a little long and complex
981 - command-output should be shown column by column
982 to reduce scrolling and to increase clarity
984 - lsmark should list the selected files with full
986 - wildcards for selecting and file and directories would be nice
987 - any actions should be interuptable with STRG+C
988 - command-expansion would be pretty cool
990 - When the replace Never option is set, new directory permissions
991 are not restored. See bug 213. To fix this requires creating a
992 list of newly restored directories so that those directory
993 permissions *can* be restored.
994 - Add prune all command
995 - Document fact that purge can destroy a part of a restore by purging
996 one volume while others remain valid -- perhaps mark Jobs.
997 - Add multiple-media-types.txt
998 - look at mxt-changer.html
999 - Make ? do a help command (no return needed).
1000 - Implement restore directory.
1001 - Document streams and how to implement them.
1002 - Try not to re-backup a file if a new hard link is added.
1003 - Add feature to backup hard links only, but not the data.
1004 - Fix stream handling to be simpler.
1005 - Add Priority and Bootstrap to Run a Job.
1006 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1008 - Remove View FileSet button from Run a Job dialog.
1009 - Handle prompt for restore job at end of Restore command.
1010 - Add display of total selected files to Restore window.
1011 - Add tree pane to left of window.
1012 - Add progress meter.
1013 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1014 - Add message to user to check for fixed block size when the forward
1015 space test fails in btape.
1016 - When unmarking a directory check if all files below are unmarked and
1017 then remove the + flag -- in the restore tree.
1018 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1019 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1020 - Revisit the question of multiple Volumes (disk) on a single device.
1021 - Add a block copy option to bcopy.
1022 - Finish work on Gnome restore GUI.
1023 - Fix "llist jobid=xx" where no fileset or client exists.
1024 - For each job type (Admin, Restore, ...) require only the really necessary
1025 fields.- Pass Director resource name as an option to the Console.
1026 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1027 - Add a .list all files in the restore tree (probably also a list all files)
1028 Do both a long and short form.
1029 - Allow browsing the catalog to see all versions of a file (with
1030 stat data on each file).
1031 - Restore attributes of directory if replace=never set but directory
1033 - Use SHA1 on authentication if possible.
1034 - See comtest-xxx.zip for Windows code to talk to USB.
1035 - Add John's appended files:
1036 Appended = { /files/server/logs/http/*log }
1037 and such files would be treated as follows.On a FULL backup, they would
1038 be backed up like any other file.On an INCREMENTAL backup, where a
1039 previous INCREMENTAL or FULL was already in thecatalogue and the length
1040 of the file wasgreater than the length of the last backup, only thedata
1041 added since the last backup will be dumped.On an INCREMENTAL backup, if
1042 the length of the file is less than thelength of the file with the same
1043 name last backed up, the completefile is dumped.On Windows systems, with
1044 creation date of files, we can be evensmarter about this and not count
1045 entirely upon the length.On a restore, the full and all incrementals
1046 since it will beapplied in sequence to restore the file.
1047 - Check new HAVE_WIN32 open bits.
1048 - Check if the tape has moved before writing.
1049 - Handling removable disks -- see below:
1050 - Keep track of tape use time, and report when cleaning is necessary.
1051 - Add FromClient and ToClient keywords on restore command (or
1052 BackupClient RestoreClient).
1053 - Implement a JobSet, which groups any number of jobs. If the
1054 JobSet is started, all the jobs are started together.
1055 Allow Pool, Level, and Schedule overrides.
1056 - Enhance cancel to timeout BSOCK packets after a specific delay.
1057 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1058 ua_status.!!! Thanks to Alan Brown for this tip.
1059 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1060 correctly for multiple simultaneous jobs.
1061 - Correct code so that FileSet MD5 is calculated for < and | filename
1063 - Implement the Media record flag that indicates that the Volume does disk
1065 - Implement VolAddr, which is used when Volume is addressed like a disk,
1066 and form it from VolFile and VolBlock.
1067 - Make multiple restore jobs for multiple media types specifying
1068 the proper storage type.
1069 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1070 pointer (rec) to try_repositioning().
1071 - Look at extracting Win data from BackupRead.
1072 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1073 which would take precidence over the Catalog "JobRetention".
1074 - Implement Label Format in Add and Label console commands.
1075 - Possibly up network buffers to 65K. Put on variable.
1076 - Put email tape request delays on one or more variables. User wants
1077 to cancel the job after a certain time interval. Maximum Mount Wait?
1078 - Job, Client, Device, Pool, or Volume?
1079 Is it possible to make this a directive which is *optional* in multiple
1080 resources, like Level? If so, I think I'd make it an optional directive
1081 in Job, Client, and Pool, with precedence such that Job overrides Client
1082 which in turn overrides Pool.
1084 - New Storage specifications:
1085 - Want to write to multiple storage devices simultaneously
1086 - Want to write to multiple storage devices sequentially (in one job)
1087 - Want to read/write simultaneously
1088 - Key is MediaType -- it must match
1090 Passed to SD as a sort of BSR record called Storage Specification
1094 MediaType -> Next MediaType
1096 Device -> Next Device
1098 Allow multiple Storage specifications
1106 Allow Multiple Pool specifications (note, Pool currently
1108 Allow Multiple MediaType specifications in Dir conf
1109 Allow Multiple Device specifications in Dir conf
1110 Perhaps keep this in a single SSR
1111 Tie a Volume to a specific device by using a MediaType that
1112 is contained in only one device.
1113 In SD allow Device to have Multiple MediaTypes
1115 - Ideas from Jerry Scharf:
1116 First let's point out some big pluses that bacula has for this
1118 more importantly it's active. Thank you so much for that
1119 even more important, it's not flaky
1120 it has an open access catalog, opening many possibilities
1121 it's pushing toward heterogeneous systems capability
1123 Macintosh file client
1124 macs are an interesting niche, but I fear a server is a rathole

1128 b) do the full catalog check (expensive but accurate)

1133 logwatch code for bacula logs (or similar)
1134 linux distro inclusion of bacula (brings good and bad, but necessary)
1135 win2k/XP server capability (icky but you asked)
1136 support for Oracle database ??
1138 - Look at adding SQL server and Exchange support for Windows.
1139 - Make dev->file and dev->block_num signed integers so that -1 can
1140 be an invalid value which happens with BSR.
1141 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1142 is needed to properly specify ranges.
1143 - Add progress of files/bytes to SD and FD.
1144 - Print warning message if FileId > 4 billion
1145 - do a "messages" before the first prompt in Console
1146 - Client does not show busy during Estimate command.
1147 - Implement Console mtx commands.
1148 - Implement a Mount Command and an Unmount Command where
1149 the users could specify a system command to be performed
1150 to do the mount, after which Bacula could attempt to
1151 read the device. This is for Removeable media such as a CDROM.
1152 - Most likely, this mount command would be invoked explicitly
1153 by the user using the current Console "mount" and "unmount"
1154 commands -- the Storage Daemon would do the right thing
1155 depending on the exact nature of the device.
1156 - As with tape drives, when Bacula wanted a new removable
1157 disk mounted, it would unmount the old one, and send a message
1158 to the user, who would then use "mount" as described above
1159 once he had actually inserted the disk.
1160 - Implement dump/print label to UA
1161 - Spool to disk only when the tape is full, then when a tape is hung move
1163 - bextract is sending everything to the log file ****FIXME****
1164 - Allow multiple Storage specifications (or multiple names on
1165 a single Storage specification) in the Job record. Thus a job
1166 can be backed up to a number of storage devices.
1167 - Implement some way for the File daemon to contact the Director
1168 to start a job or pass its DHCP obtained IP number.
1169 - Implement a query tape prompt/replace feature for a console
1170 - Copy console @ code to gnome2-console
1171 - Make tree walk routines like cd, ls, ... more user friendly
1172 by handling spaces better.
1173 - Make sure that Bacula rechecks the tape after the 20 min wait.
1174 - Set IO_NOWAIT on Bacula TCP/IP packets.
1175 - Try doing a raw partition backup and restore by mounting a
1177 - From Lars Kellers:
1178 Yes, it would allow to highly automatic the request for new tapes. If a
1179 tape is empty, bacula reads the barcodes (native or simulated), and if
1180 an unused tape is found, it runs the label command with all the
1181 necessary parameters.
1183 By the way can bacula automatically "move" an empty/purged volume say
1184 in the "short" pool to the "long" pool if this pool runs out of volume
1186 - What to do about "list files job=xxx".
1187 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1188 file descriptor leak in Bacula.
1189 - Implement WrapCounters in Counters.
1190 - Add heartbeat from FD to SD if hb interval expires.
1191 - Can we dynamically change FileSets?
1192 - If pool specified to label command and Label Format is specified,
1193 automatically generate the Volume name.
1194 - Why can't SQL do the filename sort for restore?
1195 - Add ExhautiveRestoreSearch
1196 - Look at the possibility of loading only the necessary
1197 data into the restore tree (i.e. do it one directory at a
1198 time as the user walks through the tree).
1199 - Possibly use the hash code if the user selects all for a restore command.
1200 - Fix "restore all" to bypass building the tree.
1201 - Prohibit backing up archive device (findlib/find_one.c:128)
1202 - Implement Release Device in the Job resource to unmount a drive.
1203 - Implement Acquire Device in the Job resource to mount a drive,
1204 be sure this works with admin jobs so that the user can get
1205 prompted to insert the correct tape. Possibly some way to say to
1206 run the job but don't save the files.
1207 - Make things like list where a file is saved case independent for
1209 - Use autochanger to handle multiple devices.
1210 - Implement a Recycle command
1211 - Start working on Base jobs.
1212 - Implement UnsavedFiles DB record.
1213 - From Phil Stracchino:
1214 It would probably be a per-client option, and would be called
1215 something like, say, "Automatically purge obsoleted jobs". What it
1216 would do is, when you successfully complete a Differential backup of a
1217 client, it would automatically purge all Incremental backups for that
1218 client that are rendered redundant by that Differential. Likewise,
1219 when a Full backup on a client completed, it would automatically purge
1220 all Differential and Incremental jobs obsoleted by that Full backup.
1221 This would let people minimize the number of tapes they're keeping on
1222 hand without having to master the art of retention times.
1223 - When doing a Backup send all attributes back to the Director, who
1224 would then figure out what files have been deleted.
1225 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1226 explicit permission to do so. It should also mark the tape in error
1227 if there is an error.
1228 - Cancel waiting for Client connect in SD if FD goes away.
1230 - Implement timeout in response() when it should come quickly.
1231 - Implement a Slot priority (loaded/not loaded).
1232 - Implement "vacation" Incremental only saves.
1233 - Implement create "FileSet"?
1234 - Add prefixlinks to where or not where absolute links to FD.
1235 - Issue message to mount a new tape before the rewind.
1236 - Simplified client job initiation for portables.
1237 - If SD cannot open a drive, make it periodically retry.
1238 - Add more of the config info to the tape label.
1240 - Refine SD waiting output:
1241 Device is being positioned
1242 > Device is being positioned for append
1243 > Device is being positioned to file x
1245 - Figure out some way to estimate output size and to avoid splitting
1246 a backup across two Volumes -- this could be useful for writing CDROMs
1247 where you really prefer not to have it split -- not serious.
1248 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1249 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1250 actual data on the Volume and compare it.
1251 - Implement Bacula plugins -- design API
1252 - Make bcopy read through bad tape records.
1253 - Program files (i.e. execute a program to read/write files).
1254 Pass read date of last backup, size of file last time.
1255 - Add Signature type to File DB record.
1256 - CD into subdirectory when open()ing files for backup to
1257 speed up things. Test with testfind().
1258 - Priority job to go to top of list.
1259 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1260 - Implement some way for the Console to dynamically create a job.
1261 - Solaris -I on tar for include list
1262 - Need a verbose mode in restore, perhaps to bsr.
1263 - bscan without -v is too quiet -- perhaps show jobs.
1264 - Add code to reject whole blocks if not wanted on restore.
1265 - Check if we can increase Bacula FD priorty in Win2000
1266 - Make sure the MaxVolFiles is fully implemented in SD
1267 - Check if both CatalogFiles and UseCatalog are set to SD.
1268 - Possibly add email to Watchdog if drive is unmounted too
1269 long and a job is waiting on the drive.
1270 - After unmount, if restore job started, ask to mount.
1271 - Add UA rc and history files.
1272 - put termcap (used by console) in ./configure and
1273 allow -with-termcap-dir.
1274 - Fix Autoprune for Volumes to respect need for full save.
1275 - Compare tape to Client files (attributes, or attributes and data)
1276 - Make all database Ids 64 bit.
1277 - Allow console commands to detach or run in background.
1278 - Add SD message variables to control operator wait time
1279 - Maximum Operator Wait
1280 - Minimum Message Interval
1281 - Maximum Message Interval
1282 - Send Operator message when cannot read tape label.
1283 - Verify level=Volume (scan only), level=Data (compare of data to file).
1284 Verify level=Catalog, level=InitCatalog
1286 - Add keyword search to show command in Console.
1287 - Events : tape has more than xxx bytes.
1288 - Complete code in Bacula Resources -- this will permit
1289 reading a new config file at any time.
1290 - Handle ctl-c in Console
1291 - Implement script driven addition of File daemon to config files.
1292 - Think about how to make Bacula work better with File (non-tape) archives.
1293 - Write Unix emulator for Windows.
1294 - Put memory utilization in Status output of each daemon
1295 if full status requested or if some level of debug on.
1296 - Make database type selectable by .conf files i.e. at runtime
1297 - Set flag for uname -a. Add to Volume label.
1298 - Restore files modified after date
1299 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1300 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1301 - Timout a job or terminate if link goes down, or reopen link and query.
1302 - Concept of precious tapes (cannot be reused).
1303 - Make bcopy copy with a single tape drive.
1304 - Permit changing ownership during restore.

1318 - Autolabel should be specified by DIR instead of SD.
1320 - Add media capacity
1321 - AutoScan (check checksum of tape)
1322 - Format command = "format /dev/nst0"
1326 - Seek resolution (usually corresponds to buffer size)
1327 - EODErrorCode=ENOSPC or code
1328 - Partial Read error code

1349 at end of save retry and report any errors.
1350 - Write a Storage daemon that uses pipes and
1351 standard Unix programs to write to the tape.

1354 times out jobs by asking the deamons where they are.
1355 - Enhance Jmsg code to permit buffering and saving to disk.
1356 - device driver = "xxxx" for drives.
1357 - Verify from Volume
1358 - Ensure that /dev/null works
1359 - Need report class for messages. Perhaps
1360 report resource where report=group of messages
1361 - enhance scan_attrib and rename scan_jobtype, and
1362 fill in code for "since" option
1363 - Director needs a time after which the report status is sent
1364 anyway -- or better yet, a retry time for the job.
1365 - Don't reschedule a job if previous incarnation is still running.
1366 - Some way to automatically backup everything is needed????
1367 - Need a structure for pending actions:
1369 - termination status (part of buffered msgs?)
1371 Read, Write, Clean, Delete
1372 - Login to Bacula; Bacula users with different permissions:
1373 owner, group, user, quotas
1374 - Store info on each file system type (probably in the job header on tape.
1375 This could be the output of df; or perhaps some sort of /etc/mtab record.
1377 ========= ideas ===============
1378 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1379 To: <kern@sibbald.com>
1380 Subject: RE: [Bacula-users] future large programming jobs
1381 Date: Thu, 26 Feb 2004 11:34:54 -0600
1383 I noticed the subject thread and thought I would offer the following
1384 merely as sources of ideas, i.e. something to think about, not even as
1385 strong as a request. In my former life (before retiring) I often
1386 dealt with backups and storage management issues/products as a
1387 developer and as a consultant. I am currently migrating my personal
1388 network from amanda to bacula specifically because of the ability to
1389 cross media boundaries during storing backups.
1390 Are you familiar with the commercial product called ADSM (I think IBM
1391 now sells it under the Tivoli label)? It has a couple of interesting
1392 ideas that may apply to the following topics.
1394 1. Migration: Consider that when you need to restore a system, there
1395 may be pressure to hurry. If all the information for a single client
1396 can eventually end up on the same media (and in chronological order),
1397 the restore is facillitated by not having to search past information
1398 from other clients. ADSM has the concept of "client affinity" that
1399 may be associated with it's storage pools. It seems to me that this
1400 concept (as an optional feature) might fit in your architecture for
1403 ADSM also has the concept of defining one or more storage pools as
1404 "copy pools" (almost mirrors, but only in the sense of contents).
1405 These pools provide the ability to have duplicte data stored both
1406 onsite and offsite. The copy process can be scheduled to be handled
1407 by their storage manager during periods when there is no backup
1408 activity. Again, the migration process might be a place to consider
1409 implementing something like this.
1412 > It strikes me that it would be very nice to be able to do things
1414 > have the Job(s) backing up the machines run, and once they have all

1420 > mechanism described below would probably make it very easy.
1422 This is the goal. In the first step (before events), you simply
1424 the Migration to tape later.
1426 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1427 the database. Once a file (unique by path and metadata such as dates,
1428 size, ownership, etc.) is in a copy pool, no more copies are made. In
1429 other words, when you start ADSM, it begins like your concept of a
1430 base job. After that it is in the "incremental" mode. You can
1431 configure the number of "generations" of files to be retained, plus a
1432 retention date after which even old generations are purged. The
1433 database tracks the contents of media and projects the percentage of
1434 each volume that is valid. When the valid content of a volume drops
1435 below a configured percentage, the valid data are migrated to another
1436 volume and the old volume is marked as empty. Note, this requires
1437 ADSM to have an idea of the contents of a client, i.e. marking the
1438 database when an existing file was deleted, but this would solve your
1439 issue of restoring a client without restoring deleted files.
1441 This is pretty far from what bacula now does, but if you are going to
1442 rip things up for Base jobs,.....
1443 Also, the benefits of this are huge for very large shops, especially
1444 with media robots, but are a pain for shops with manual media
1448 > Base jobs sound pretty useful, but I'm not dying for them.
1450 Nobody is dying for them, but when you see what it does, you will die
1453 3. Restoring deleted files: Since I think my comments in (2) above
1454 have low probability of implementation, I'll also suggest that you
1455 could approach the issue of deleted files by a mechanism of having the
1456 fd report to the dir, a list of all files on the client for every
1457 backup job. The dir could note in the database entry for each file
1458 the date that the file was seen. Then if a restore as of date X takes
1459 place, only files that exist from before X until after X would be
1460 restored. Probably the major cost here is the extra date container in
1461 each row of the files table.
1463 Thanks for "listening". I hope some of this helps. If you want to
1464 contact me, please send me an email - I read some but not all of the
1465 mailing list traffic and might miss a reply there.
1467 Please accept my compliments for bacula. It is doing a great job for
1468 me!! I sympathize with you in the need to wrestle with excelence in
1469 execution vs. excelence in feature inclusion.
1474 ==============================
1477 - Design at hierarchial storage for Bacula. Migration and Clone.
1478 - Implement FSM (File System Modules).
1479 - Audit M_ error codes to ensure they are correct and consistent.
1480 - Add variable break characters to lex analyzer.
1481 Either a bit mask or a string of chars so that
1482 the caller can change the break characters.
1483 - Make a single T_BREAK to replace T_COMMA, etc.
1484 - Ensure that File daemon and Storage daemon can
1485 continue a save if the Director goes down (this
1486 is NOT currently the case). Must detect socket error,
1487 buffer messages for later.
1488 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1489 - Add ability to backup to two Storage devices (two SD sessions) at
1490 the same time -- e.g. onsite, offsite.
1491 - Add the ability to consolidate old backup sets (basically do a restore
1492 to tape and appropriately update the catalog). Compress Volume sets.
1493 Might need to spool via file is only one drive is available.
1494 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1495 someway to do so with every volume that has less than x% valid
1499 Migration: Move a backup from one Volume to another
1500 Clone: Copy a backup -- two Volumes
1503 ======================================================
1505 It is somewhat like a Full save becomes an incremental since
1506 the Base job (or jobs) plus other non-base files.
1508 - A Base backup is same as Full backup, just different type.
1509 - New BaseFiles table that contains:
1511 BaseJobId - Base JobId referenced for this FileId (needed ???)
1512 JobId - JobId currently running
1513 FileId - File not backed up, exists in Base Job
1514 FileIndex - FileIndex from Base Job.
1515 i.e. for each base file that exists but is not saved because
1516 it has not changed, the File daemon sends the JobId, BaseId,
1517 FileId, FileIndex back to the Director who creates the DB entry.
1518 - To initiate a Base save, the Director sends the FD
1519 the FileId, and full filename for each file in the Base.
1520 - When the FD finds a Base file, he requests the Director to
1521 send him the full File entry (stat packet plus MD5), or
1522 conversely, the FD sends it to the Director and the Director
1523 says yes or no. This can be quite rapid if the FileId is kept
1524 by the FD for each Base Filename.
1525 - It is probably better to have the comparison done by the FD
1526 despite the fact that the File entry must be sent across the
1528 - An alternative would be to send the FD the whole File entry
1529 from the start. The disadvantage is that it requires a lot of
1530 space. The advantage is that it requires less communications
1532 - The Job record must be updated to indicate that one or more
1534 - At end of Job, FD returns:
1535 1. Count of base files/bytes not written to tape (i.e. matches)
1536 2. Count of base file that were saved i.e. had changed.
1537 - No tape record would be written for a Base file that matches, in the
1538 same way that no tape record is written for Incremental jobs where
1539 the file is not saved because it is unchanged.
1540 - On a restore, all the Base file records must explicitly be
1541 found from the BaseFile tape. I.e. for each Full save that is marked
1542 to have one or more Base Jobs, search the BaseFile for all occurrences
1544 - An optimization might be to make the BaseFile have:
1550 This would avoid the need to explicitly fetch each File record for
1551 the Base job. The Base Job record will be fetched to get the
1552 VolSessionId and VolSessionTime.
1553 =========================================================
1556 ==========================================================
1558 For each Incremental job that is run, there may be files that
1559 were found but not saved because they were locked (this applies
1560 only to Windows). Such a system could send back to the Director
1561 a list of Unsaved files.
1563 - New UnSavedFiles table that contains:
1567 - Then in the next Incremental job, the list of Unsaved Files will be
1568 feed to the FD, who will ensure that they are explicitly chosen even
1569 if standard date/time check would not have selected them.

1614 There needs to be a table of drive # to devices somewhere - If there are
1615 multiple changers or drives there may not be a 1:1 correspondance between
1616 changer drive number and system device name - and depending on the way the
1617 drives are hooked up to scsi busses, they may not be linearly numbered
1618 from an offset point either.something like
1620 Autochanger drives = 2
1621 Autochanger drive 0 = /dev/nst1
1622 Autochanger drive 1 = /dev/nst2
1623 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1624 times, not just for multidrive changers. For a 1 drive changer, that's
1630 MTX's manpage (1.2.15):
1631 unload [<slotnum>] [ <drivenum> ]
1632 Unloads media from drive <drivenum> into slot
1633 <slotnum>. If <drivenum> is omitted, defaults to
1634 drive 0 (as do all commands). If <slotnum> is
1635 omitted, defaults to the slot that the drive was
1636 loaded from. Note that there's currently no way
1637 to say 'unload drive 1's media to the slot it
1638 came from', other than to explicitly use that
1639 slot number as the destination.AB

1677 Handling removable disks
1679 From: Karl Cunningham <karlc@keckec.com>
1681 My backups are only to hard disk these days, in removable bays. This is my
1682 idea of how a backup to hard disk would work more smoothly. Some of these
1683 things Bacula does already, but I mention them for completeness. If others
1684 have better ways to do this, I'd like to hear about it.
1686 1. Accommodate several disks, rotated similar to how tapes are. Identified
1687 by partition volume ID or perhaps by the name of a subdirectory.
1688 2. Abort & notify the admin if the wrong disk is in the bay.
1689 3. Write backups to different subdirectories for each machine to be backed
1691 4. Volumes (files) get created as needed in the proper subdirectory, one
1693 5. When a disk is recycled, remove or zero all old backup files. This is
1694 important as the disk being recycled may be close to full. This may be
1695 better done manually since the backup files for many machines may be
1696 scattered in many subdirectories.
1701 - Why the heck doesn't bacula drop root priviledges before connecting to
1703 - Look at using posix_fadvise(2) for backups -- see bug #751.
1704 Possibly add the code at findlib/bfile.c:795
1705 /* TCP socket options */
1706 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1707 - Fix bnet_connect() code to set a timer and to use time to
1709 - Implement 4th argument to make_catalog_backup that passes hostname.
1710 - Test FIFO backup/restore -- make regression
1711 - Please mount volume "xxx" on Storage device ... should also list
1712 Pool and MediaType in case user needs to create a new volume.
1713 - On restore add Restore Client, Original Client.
