12 - Does WildFile match against full name? Doc.
13 - %d and %v only valid on Director, not for ClientRunBefore/After.
14 - During tests with the 260 char fix code, I found one problem:
15 if the system "sees" a long path once, it seems to forget it's
16 working drive (e.g. c:\), which will lead to a problem during
17 the next job (create bootstrap file will fail). Here is the
18 workaround: specify absolute working and pid directory in
19 bacula-fd.conf (e.g. c:\bacula\working instead of
21 - Document techniques for restoring large numbers of files.

63 Threshold triggered migration jobs (not currently in list, but will be
65 Client triggered backups
66 Complete rework of the scheduling system (not in list)
67 Performance and usage instrumentation (not in list)
68 See email of 21Aug2007 for details.
69 - Look at: http://tech.groups.yahoo.com/group/cfg2html
70 and http://www.openeyet.nl/scc/ for managing customer changes
74 - New directive "Delete purged Volumes"
76 - Prune by Job Level (Full, Differential, Incremental)
77 - Strict automatic pruning
78 - Implement unmount of USB volumes.
79 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
80 Win32 to avoid patent problems.
81 - Implement Bacula plugins -- design API
82 - modify pruning to keep a fixed number of versions of a file,
84 - the cd-command should allow complete paths
85 i.e. cd /foo/bar/foo/bar
86 -> if a customer mails me the path to a certain file,
87 its faster to enter the specified directory
88 - Fix bpipe.c so that it does not modify results pointer.
89 ***FIXME*** calling sequence should be changed.
90 - Make tree walk routines like cd, ls, ... more user friendly
91 by handling spaces better.
95 MA = (last_MA * 3 + rate) / 4
96 rate = (bytes - last_bytes) / (runtime - last_runtime)
97 - Add a recursive mark command (rmark) to restore.
98 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
99 of the same level and does not permit multiple simultaneous
100 running of that Job (i.e. lets any previous invocation finish
101 before doing Interval testing).
102 - Look at simplifying File exclusions.
104 - Auto update of slot:
105 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
106 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

114 - Eliminate: /var is a different filesystem. Will not descend from / into /var
115 - Separate Files and Directories in catalog
116 - Create FileVersions table
117 - Look at rsysnc for incremental updates and dedupping
118 - Add MD5 or SHA1 check in SD for data validation
119 - finish implementation of fdcalled -- see ua_run.c:105
120 - Fix problem in postgresql.c in my_postgresql_query, where the
121 generation of the error message doesn't differentiate result==NULL
122 and a bad status from that result. Not only that, the result is
123 cleared on a bail_out without having generated the error message.
125 - Implement SDErrors (must return from SD)
126 - Implement USB keyboard support in rescue CD.
127 - Implement continue spooling while despooling.
128 - Remove all install temp files in Win32 PLUGINSDIR.
129 - Audit retention periods to make sure everything is 64 bit.
130 - No where in restore causes kaboom.
131 - Performance: multiple spool files for a single job.
132 - Performance: despool attributes when despooling data (problem
133 multiplexing Dir connection).
134 - Make restore use the in-use volume reservation algorithm.
135 - When Pool specifies Storage command override does not work.
136 - Implement wait_for_sysop() message display in wait_for_device(), which
137 now prints warnings too often.
138 - Ensure that each device in an Autochanger has a different
140 - Look at sg_logs -a /dev/sg0 for getting soft errors.
141 - btape "test" command with Offline on Unmount = yes
143 This test is essential to Bacula.
145 I'm going to write one record in file 0,
146 two records in file 1,
147 and three records in file 2
149 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715

152 Kaboom! btape, btape got signal 11. Attempting traceback.
154 - Encryption -- email from Landon
155 > The backup encryption algorithm is currently not configurable, and is
156 > set to AES_128_CBC in src/filed/backup.c. The encryption code
157 > supports a number of different ciphers (as well as adding arbitrary
158 > new ones) -- only a small bit of code would be required to map a
159 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is

162 - Figure out some way to "automatically" backup conf changes.
163 - Add the OS version back to the Win32 client info.
164 - Restarted jobs have a NULL in the from field.
165 - Modify SD status command to indicate when the SD is writing
166 to a DVD (the device is not open -- see bug #732).
167 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
168 and possibly changing the blobs into varchar.
169 - Ensure that the SD re-reads the Media record if the JobFiles
170 does not match -- it may have been updated by another job.
172 - Test Volume compatibility between machine architectures
173 - Encryption documentation
174 - Wrong jobbytes with query 12 (todo)
175 - Bare-metal recovery Windows (todo)
180 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
182 - Maximum number of scratch volumes
184 - Next Pool (already have)
185 - Reclamation threshold
187 - Reuse delay (after all files purged from volume before it can be used)
188 - Copy Pool = xx, yyy (or multiple lines).
190 - Allow pool selection during restore.
192 - Average tape size from Eric
193 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg

204 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
205 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
209 - Add doc for bweb -- especially Installation
211 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
213 - Despool attributes in separate thread
216 - Check why restore repeatedly sends Rechdrs between
217 each data chunk -- according to James Harper 9Jan07.
220 - Full at least once a month, ...
221 - Cancel Inc if Diff/Full running
222 - More intelligent re-run
223 - New/deleted file backup
225 - Incremental backup -- rsync, Stow
229 - Try to fix bscan not working with multiple DVD volumes bug #912.
230 - Look at mondo/mindi
231 - Make Bacula by default not backup tmpfs, procfs, sysfs, ...
232 - Fix hardlinked immutable files when linking a second file, the
233 immutable flag must be removed prior to trying to link it.
234 - Implement Python event for backing up/restoring a file.
235 - Change dbcheck to tell users to use native tools for fixing
236 broken databases, and to ensure they have the proper indexes.
237 - add udev rules for Bacula devices.
238 - If a job terminates, the DIR connection can close before the
239 Volume info is updated, leaving the File count wrong.
240 - Look at why SIGPIPE during connection can cause seg fault in
241 writing the daemon message, when Dir dropped to bacula:bacula
242 - Look at zlib 32 => 64 problems.
243 - Possibly turn on St. Bernard code.
244 - Fix bextract to restore ACLs, or better yet, use common routines.
245 - Do we migrate appendable Volumes?
246 - Remove queue.c code.
247 - Print warning message if LANG environment variable does not specify
249 - New dot commands from Arno.
250 .show device=xxx lists information from one storage device, including
251 devices (I'm not even sure that information exists in the DIR...)
252 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
253 better machine-readable output like "Ok" or "Error busy"
254 .move eject device=xxx toslot=yyy the same as above, but with a new
255 target slot. The catalog should be updated accordingly.
256 .move transfer device=xxx fromslot=yyy toslot=zzz

286 - Possibly allow SD to spool even if a tape is not mounted.
287 - Fix re-read of last block to check if job has actually written
288 a block, and check if block was written by a different job
289 (i.e. multiple simultaneous jobs writing).
290 - Figure out how to configure query.sql. Suggestion to use m4:
291 == changequote.m4 ===
292 changequote(`[',`]')dnl
293 ==== query.sql.in ===
294 :List next 20 volumes to expire

307 ON Media.PoolId=Pool.PoolId
308 WHERE Media.LastWritten>0
312 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
314 The problem is that it requires m4, which is not present on all machines
316 - Given all the problems with FIFOs, I think the solution is to do something a
317 little different, though I will look at the code and see if there is not some
318 simple solution (i.e. some bug that was introduced). What might be a better
319 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
320 write data to a program rather than the FIFO. For example, suppose you
325 Then, I could imagine if you backup and restore this file with a direct
326 reference as is currently done for fifos, instead, during backup Bacula will
329 /home/kern/my-fifo.backup
331 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
334 /home/kern/my-fifo.restore
336 and send the data backed up to stdout. These programs can either be an
337 executable or a shell script and they need only read/write to stdin/stdout.
339 I think this would give a lot of flexibility to the user without making any
340 significant changes to Bacula.

465 If this is not a blank tape, try unmounting and remounting the Volume.
467 - http://www.dwheeler.com/essays/commercial-floss.html
468 - Add VolumeLock to prevent all but lock holder (SD) from updating
469 the Volume data (with the exception of VolumeState).
470 - The btape fill command does not seem to use the Autochanger
471 - Make Windows installer default to system disk drive.
472 - Look at using ioctl(FIOBMAP, ...) on Linux, and
473 DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
474 Win32 for sparse files.

478 - Command: pycmd "command" generates "command" event. How to
479 attach to a specific job?
480 - Integrate Christopher's St. Bernard code.
481 - run_cmd() returns int should return JobId_t
482 - get_next_jobid_from_list() returns int should return JobId_t

492 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
493 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
494 - Implement a mode that says when a hard read error is
495 encountered, read many times (as it currently does), and if the
496 block cannot be read, skip to the next block, and try again. If
497 that fails, skip to the next file and try again, ...
499 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
500 insert into LevelType (LevelType,LevelTypeLong) values
504 - Show files/second in client status output.
505 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
506 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
507 see if it become stable and I just have to supervise
509 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
510 PoolId, and when it is empty remove it.
512 - Allow Check Labels to be used with Bacula labels.
513 - "Resuming" a failed backup (lost line for example) by using the
514 failed backup as a sort of "base" job.
516 - Email to the user when the tape is about to need changing x
517 days before it needs changing.
518 - Command to show next tape that will be used for a job even
519 if the job is not scheduled.
520 - From: Arunav Mandal <amandal@trolltech.com>
521 1. When jobs are running and bacula for some reason crashes or if I do a
522 restart it remembers and jobs it was running before it crashed or restarted
523 as of now I loose all jobs if I restart it.
525 2. When spooling and in the midway if client is disconnected for instance a
526 laptop bacula completely discard the spool. It will be nice if it can write
527 that spool to tape so there will be some backups for that client if not all.
529 3. We have around 150 clients machines it will be nice to have a option to
530 upgrade all the client machines bacula version automatically.
532 4. Atleast one connection should be reserved for the bconsole so at heavy load
533 I should connect to the director via bconsole which at sometimes I can't
535 5. Another most important feature that is missing, say at 10am I manually
536 started backup of client abc and it was a full backup since client abc has
537 no backup history and at 10.30am bacula again automatically started backup of
538 client abc as that was in the schedule. So now we have 2 multiple Full
539 backups of the same client and if we again try to start a full backup of
540 client backup abc bacula won't complain. That should be fixed.
542 - For Windows disaster recovery see http://unattended.sf.net/
543 - regardless of the retention period, Bacula will not prune the
544 last Full, Diff, or Inc File data until a month after the
545 retention period for the last Full backup that was done.
546 - update volume=xxx --- add status=Full
547 - Remove old spool files on startup.
548 - Exclude SD spool/working directory.
549 - Refuse to prune last valid Full backup. Same goes for Catalog.
551 - Make a callback when Rerun failed levels is called.
552 - Give Python program access to Scheduled jobs.
553 - Add setting Volume State via Python.
554 - Python script to save with Python, not save, save with Bacula.
555 - Python script to do backup.
557 - Change the Priority, Client, Storage, JobStatus (error)
558 at the start of a job.
559 - Why is SpoolDirectory = /home/bacula/spool; not reported
560 as an error when writing a DVD?
561 - Make bootstrap file handle multiple MediaTypes (SD)
562 - Remove all old Device resource code in Dir and code to pass it
563 back in SD -- better, rework it to pass back device statistics.
564 - Check locking of resources -- be sure to lock devices where previously
565 resources were locked.
566 - The last part is left in the spool dir.
569 - In restore don't compare byte count on a raw device -- directory
570 entry does not contain bytes.
573 - Max Vols limit in Pool off by one?
574 - Implement Files/Bytes,... stats for restore job.
575 - Implement Total Bytes Written, ... for restore job.
576 - Despool attributes simultaneously with data in a separate
577 thread, rejoined at end of data spooling.
578 - 7. Implement new Console commands to allow offlining/reserving drives,
579 and possibly manipulating the autochanger (much asked for).
580 - Add start/end date editing in messages (%t %T, %e?) ...
581 - Add ClientDefs similar to JobDefs.
582 - Print more info when bextract -p accepts a bad block.
583 - Fix FD JobType to be set before RunBeforeJob in FD.
584 - Look at adding full Volume and Pool information to a Volume
585 label so that bscan can get *all* the info.
586 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
587 and there is only one volume in the pool, refuse to do it -- otherwise
588 he fills the Volume, then immediately starts reusing it.
589 - Implement copies and stripes.
590 - Add history file to console.
591 - Each file on tape creates a JobMedia record. Peter has 4 million
592 files spread over 10000 tape files and four tapes. A restore takes
593 16 hours to build the restore list.
594 - Add and option to check if the file size changed during backup.
595 - Make sure SD deletes spool files on error exit.
596 - Delete old spool files when SD starts.
597 - When labeling tapes, if you enter 000026, Bacula uses
598 the tape index rather than the Volume name 000026.
599 - Add offline tape command to Bacula console.
601 Enter MediaId or Volume name: 32
602 Enter new Volume name: DLT-20Dec04

613 - Bug: if a job is manually scheduled to run later, it does not appear
614 in any status report and cannot be cancelled.
616 ==== Keeping track of deleted/new files ====
617 - To mark files as deleted, run essentially a Verify to disk, and
618 when a file is found missing (MarkId != JobId), then create
619 a new File record with FileIndex == -1. This could be done
620 by the FD at the same time as the backup.
622 My "trick" for keeping track of deletions is the following.
623 Assuming the user turns on this option, after all the files
624 have been backed up, but before the job has terminated, the
625 FD will make a pass through all the files and send their
626 names to the DIR (*exactly* the same as what a Verify job
627 currently does). This will probably be done at the same
628 time the files are being sent to the SD avoiding a second
629 pass. The DIR will then compare that to what is stored in
630 the catalog. Any files in the catalog but not in what the
631 FD sent will receive a catalog File entry that indicates
632 that at that point in time the file was deleted. This
633 either transmitted to the FD or simultaneously computed in
634 the FD, so that the FD can put a record on the tape that
635 indicates that the file has been deleted at this point.
636 A delete file entry could potentially be one with a FileIndex
637 of 0 or perhaps -1 (need to check if FileIndex is used for
638 some other thing as many of the Bacula fields are "overloaded"
641 During a restore, any file initially picked up by some
642 backup (Full, ...) then subsequently having a File entry
643 marked "delete" will be removed from the tree, so will not
644 be restored. If a file with the same name is later OK it
645 will be inserted in the tree -- this already happens. All
646 will be consistent except for possible changes during the
649 Since I'm on the subject, some of you may be wondering what
650 the utility of the in memory tree is if you are going to
651 restore everything (at least it comes up from time to time
652 on the list). Well, it is still *very* useful because it
653 allows only the last item found for a particular filename
654 (full path) to be entered into the tree, and thus if a file
655 is backed up 10 times, only the last copy will be restored.
656 I recently (last Friday) restored a complete directory, and
657 the Full and all the Differential and Incremental backups
658 spanned 3 Volumes. The first Volume was not even mounted
659 because all the files had been updated and hence backed up
660 since the Full backup was made. In this case, the tree
661 saved me a *lot* of time.
663 Make sure this information is stored on the tape too so
664 that it can be restored directly from the tape.
666 All the code (with the exception of formally generating and
667 saving the delete file entries) already exists in the Verify
668 Catalog command. It explicitly recognizes added/deleted files since
669 the last InitCatalog. It is more or less a "simple" matter of
670 taking that code and adapting it slightly to work for backups.
672 Comments from Martin Simmons (I think they are all covered):
673 Ok, that should cover the basics. There are few issues though:
675 - Restore will depend on the catalog. I think it is better to include the
676 extra data in the backup as well, so it can be seen by bscan and bextract.
678 - I'm not sure if it will preserve multiple hard links to the same inode. Or
679 maybe adding or removing links will cause the data to be dumped again?
681 - I'm not sure if it will handle renamed directories. Possibly it will work
682 by dumping the whole tree under a renamed directory?
684 - It remains to be seen how the backup performance of the DIR's will be
685 affected when comparing the catalog for a large filesystem.
687 1. Use the current Director in-memory tree code (very fast), but currently in
688 memory. It probably could be paged.
690 2. Use some DB such as Berkeley DB or SQLite. SQLite is already compiled and
691 built for Win32, and it is something we could compile into the program.
693 3. Implement our own custom DB code.
695 Note, by appropriate use of Directives in the Director, we can dynamically
696 decide if the work is done in the Director or in the FD, and we can even
697 allow the user to choose.
699 === most recent accurate file backup/restore ===
700 Here is a sketch (i.e. more details must be filled in later) that I recently
701 made of an algorithm for doing Accurate Backup.
703 1. Dir informs FD that it is doing an Accurate backup and lookup done by
706 2. FD passes through the file system doing a normal backup based on normal
707 conditions, recording the names of all files and their attributes, and
708 indicating which files were backed up. This is very similar to what Verify
711 3. The Director receives the two lists of files at the end of the FD backup.
712 One, files backed up, and one files not backed up. It then looks up all the
713 files not backed up (using Verify style code).
715 4. The Dir sends the FD a list of:
716 a. Additional files to backup (based on user specified criteria, name, size
717 inode date, hash, ...).
720 5. Dir deletes list of file not backed up.
722 6. FD backs up additional files generates a list of those backed up and sends
723 it to the Director, which adds it to the list of files backed up. The list
724 is now complete and current.
726 7. The FD generates delete records for all the files that were deleted and
729 8. The Dir deletes the previous CurrentBackup list, and then does a
730 transaction insert of the new list that it has.
732 9. The rest works as before ...
736 Two new tables needed.
737 1. CurrentBackupId table that contains Client, JobName, FileSet, and a unique
738 BackupId. This is created during a Full save, and the BackupId can be set to
739 the JobId of the Full save. It will remain the same until another Full
740 backup is done. That is when new records are added during a Differential or
741 Incremental, they must use the same BackupId.
743 2. CurrentBackup table that contains essentially a File record (less a number
744 of fields, but with a few extra fields) -- e.g. a flag that the File was
745 backed up by a Full save (this permits doing a Differential). The unique
746 BackupId allows us to look up the CurrentBackup for a particular Client,
747 Jobname, FileSet using that unique BackupId as the key, so this table must be
748 indexed by the BackupId.
750 Note any time a file is saved by the FD other than during a Full save, the
751 Full save flag is cleared. When doing a Differential backup, if a file has
752 the Full save flag set, it is skipped, otherwise it is backed up. For an
753 Incremental backup, we check to see if the file has changed since the last
754 time we backed it up.
756 Deleted files should have FileIndex == 0
760 How about introducing a Type = MgmtPolicy job type? That job type would
761 be responsible for scanning the Bacula environment looking for specific
762 conditions, and submitting the appropriate jobs for implementing said
766 Name = "Migration-Policy"
768 Policy Selection Job Type = Migrate
769 Scope = "<keyword> <operator> <regexp>"
770 Threshold = "<keyword> <operator> <regexp>"
771 Job Template = <template-name>
774 Where <keyword> is any legal job keyword, <operator> is a comparison
775 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
776 appropriate regexp. I could see an argument for Scope and Threshold
777 being SQL queries if we want to support full flexibility. The
778 Migration-Policy job would then get scheduled as frequently as a site
779 felt necessary (suggested default: every 15 minutes).
784 Name = "Migration-Policy"
786 Policy Selection Job Type = Migration
788 Threshold = "Migration Selection Type = LowestUtil"
789 Job Template = "MigrationTemplate"
792 would select all pools for examination and generate a job based on
793 MigrationTemplate to automatically select the volume with the lowest
794 usage and migrate it's contents to the nextpool defined for that pool.
796 This policy abstraction would be really handy for adjusting the behavior
797 of Bacula according to site-selectable criteria (one thing that pops
798 into mind is Amanda's ability to automatically adjust backup levels
799 depending on various criteria).
805 - Add Pool/Storage override regression test.
806 - Add delete JobId to regression.
807 - Add a regression test for dbcheck.
808 - New test to add bscan to four-concurrent-jobs regression,
809 i.e. after the four-concurrent jobs zap the
810 database as is done in the bscan-test, then use bscan to
811 restore the database, do a restore and compare with the
813 - Add restore of specific JobId to regression (item 3
814 on the restore prompt)
815 - Add IPv6 to regression
816 - Add database test to regression. Test each function like delete,
819 - AntiVir can slow down backups on Win32 systems.
820 - Win32 systems with FAT32 can be much slower than NTFS for
821 more than 1000 files per directory.
825 - A HOLD command to stop all jobs from starting.
826 - A PAUSE command to pause all running jobs ==> release the

829 Media Type Read = LTO,LTO2,LTO3
830 Media Type Write = LTO2, LTO3
832 === From Carsten Menke <bootsy52@gmx.net>
834 Following is a list of what I think in the situations where I'm faced with,
835 could be a usefull enhancement to bacula, which I'm certain other users will
836 benefit from as well.
838 1. NextJob/NextJobs Directive within a Job Resource in the form of
839 NextJobs = job1,job2.
842 I currently solved the problem with running multiple jobs each after each
843 by setting the Max Wait Time for a job to 8 hours, and give
844 the jobs different Priorities. However, there scenarios where
845 1 Job is directly depending on another job, so if the former job fails,
846 the job after it needn't to be run
847 while maybe other jobs should run despite of that
850 A Backup Job and a Verify job, if the backup job fails there is no need to run
851 the verify job, as the backup job already failed. However, one may like
852 to backup the Catalog to disk despite of that the main backup job failed.
855 I see that this is related to the Event Handlers which are on the ToDo
856 list, also it is maybe a good idea to check for the return value and
857 execute different actions based on the return value
860 3. offline capability to bconsole
863 Currently I use a script which I execute within the last Job via the
864 RunAfterJob Directive, to release and eject the tape.
865 So I have to call bconsole "release=Storage-Name" and afterwards
866 mt -f /dev/nst0 eject to get the tape out.
868 If I have multiple Storage Devices, than these may not be /dev/nst0 and
869 I have to modify the script or call it with parameters etc.
870 This would actually not be needed, as everything is already defined
871 in bacula-sd.conf and if I can invoke bconsole with the
872 storage name via $1 in the script than I'm done and information is
875 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
879 For the reason mentioned in 3. to have the ability to call a
880 script with /scripts/foobar %s and in the script use $1
881 to pass the Storage Name to bconsole
883 5. Setting Volume State within a Job Resource
886 Instead of using "Maximum Volume Jobs" in the Pool Resource,
887 I would have the possibilty to define
888 in a Job Resource that after this certain job is run, the Volume State
889 should be set to "Volume State = Used", this give more flexibility (IMHO).
891 6. Localization of Bacula Messages
894 Unfortunatley many,many people I work with don't speak english very well.
895 So if at least the Reporting messages would be localized then they
896 would understand that they have to change the tape,etc. etc.
898 I volunteer to do the german translations, and if I can convince my wife also
899 french and Morre (western african language).
901 7. OK, this is evil, probably bound to security risks and maybe not possible
902 due to the design of bacula.
904 Implementation of Backtics ( `command` ) for shell comand execution to
905 the "Label Format" Directive.
909 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
910 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
911 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
912 the localized name for the day of the week appended to the
913 format string. Then I have the tape labeled automatically with weekday
914 name in the correct language.
916 - Make output from status use html table tags for nicely
917 presenting in a browser.
918 - Can one write tapes faster with 8192 byte block sizes?
919 - Document security problems with the same password for everyone in
920 rpm and Win32 releases.
921 - Browse generations of files.
922 - I've seen an error when my catalog's File table fills up. I
923 then have to recreate the File table with a larger maximum row
924 size. Relevant information is at
925 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
926 "Installing and Configuring MySQL" chapter should talk a bit
927 about this potential problem, and recommend a solution.
928 - For Solaris must use POSIX awk.
929 - Want speed of writing to tape while despooling.
930 - Supported autochanger:
938 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
939 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
940 - Add regex from http://www.pcre.org to Bacula for Win32.
941 - Use only shell tools no make in CDROM package.
942 - Include within include does it work?
943 - Implement a Pool of type Cleaning?
944 - Implement VolReadTime and VolWriteTime in SD
945 - Modify Backing up Your Database to include a bootstrap file.
946 - Think about making certain database errors fatal.
947 - Look at correcting the time jump in the scheduler for daylight
948 savings time changes.
949 - Add a "real" timer to network connections.
950 - Promote to Full = Time period
951 - Check dates entered by user for correctness (month/day/... ranges)
952 - Compress restore Volume listing by date and first file.
953 - Look at patches/bacula_db.b2z postgresql that loops during restore.
955 - Perhaps add read/write programs and/or plugins to FileSets.
956 - How to handle backing up portables ...
957 - Add some sort of guaranteed Interval for upgrading jobs.
958 - Can we write the state file after every job terminates? On Win32
959 the system crashes and the state file is not updated.
962 Documentation to do: (any release a little bit at a time)
963 - Doc to do unmount before removing magazine.
964 - Alternative to static linking "ldd prog" save all binaries listed,
965 restore them and point LD_LIBRARY_PATH to them.
966 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
967 - Document query file format.
968 - Add more documentation for bsr files.
969 - Document problems with Verify and pruning.
970 - Document how to use multiple databases.
971 - VXA drives have a "cleaning required"
972 indicator, but Exabyte recommends preventive cleaning after every 75
975 In this context, it should be noted that Exabyte has a command-line
976 vxatool utility available for free download. (The current version is
977 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
978 test the drive, unload tapes, change drive settings, flash new firmware,
980 Of particular interest in this context is that vxatool <device> -i will
981 report, among other details, the time since last cleaning in tape motion
982 minutes. This information can be retrieved (and settings changed, for
983 that matter) through the generic-SCSI device even when Bacula has the
984 regular tape device locked. (Needless to say, I don't recommend
985 changing tape settings while a job is running.)
986 - Lookup HP cleaning recommendations.
987 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
988 - Document doing table repair
991 ===================================
992 - Add macro expansions in JobDefs.
993 Run Before Job = "SomeFile %{Level} %{Client}"
994 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
995 - Use non-blocking network I/O but if no data is available, use
997 - Use gather write() for network I/O.
998 - Autorestart on crash.
999 - Add bandwidth limiting.
1000 - Add acks every once and a while from the SD to keep
1001 the line from timing out.
1002 - When an error in input occurs and conio beeps, you can back
1003 up through the prompt.
1004 - Detect fixed tape block mode during positioning by looking at
1005 block numbers in btape "test". Possibly adjust in Bacula.
1006 - Fix list volumes to output volume retention in some other
1007 units, perhaps via a directive.
1008 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
1009 with multiple priorities.
1010 - If you use restore replace=never, the directory attributes for
1011 non-existent directories will not be restored properly.
1013 - see lzma401.zip in others directory for new compression
1015 - Allow the user to select JobType for manual pruning/purging.
1016 - bscan does not put first of two volumes back with all info in
1018 - Implement the FreeBSD nodump flag in chflags.
1019 - Figure out how to make named console messages go only to that
1020 console and to the non-restricted console (new console class?).
1021 - Make restricted console prompt for password if *ask* is set or
1022 perhaps if password is undefined.
1023 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1026 ==== from Marc Schoechlin
1027 - the help-command should be more verbose
1028 (it should explain the paramters of the different
1030 -> its time-comsuming to consult the manual anytime
1031 you need a special parameter
1032 -> maybe its more easy to maintain this, if the
1033 descriptions of that commands are outsourced to
1035 - if the password is not configured in bconsole.conf
1036 you should be asked for it.
1037 -> sometimes you like to do restore on a customer-machine
1038 which shouldnt know the password for bacula.
1039 -> adding the password to the file favours admins
1040 to forget to remove the password after usage
1042 the protection of that file is less important
1043 - long-listed-output of commands should be scrollable
1044 like the unix more/less-command does
1045 -> if someone runs 200 and more machines, the lists could
1046 be a little long and complex
1047 - command-output should be shown column by column
1048 to reduce scrolling and to increase clarity
1050 - lsmark should list the selected files with full
1052 - wildcards for selecting and file and directories would be nice
1053 - any actions should be interuptable with STRG+C
1054 - command-expansion would be pretty cool
1056 - When the replace Never option is set, new directory permissions
1057 are not restored. See bug 213. To fix this requires creating a
1058 list of newly restored directories so that those directory
1059 permissions *can* be restored.
1060 - Add prune all command
1061 - Document fact that purge can destroy a part of a restore by purging
1062 one volume while others remain valid -- perhaps mark Jobs.
1063 - Add multiple-media-types.txt
1064 - look at mxt-changer.html
1065 - Make ? do a help command (no return needed).
1066 - Implement restore directory.
1067 - Document streams and how to implement them.
1068 - Try not to re-backup a file if a new hard link is added.
1069 - Add feature to backup hard links only, but not the data.
1070 - Fix stream handling to be simpler.
1071 - Add Priority and Bootstrap to Run a Job.
1072 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1074 - Remove View FileSet button from Run a Job dialog.
1075 - Handle prompt for restore job at end of Restore command.
1076 - Add display of total selected files to Restore window.
1077 - Add tree pane to left of window.
1078 - Add progress meter.
1079 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1080 - Add message to user to check for fixed block size when the forward
1081 space test fails in btape.
1082 - When unmarking a directory check if all files below are unmarked and
1083 then remove the + flag -- in the restore tree.
1084 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1085 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1086 - Revisit the question of multiple Volumes (disk) on a single device.
1087 - Add a block copy option to bcopy.
1088 - Finish work on Gnome restore GUI.
1089 - Fix "llist jobid=xx" where no fileset or client exists.
1090 - For each job type (Admin, Restore, ...) require only the really necessary
1091 fields.- Pass Director resource name as an option to the Console.
1092 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1093 - Add a .list all files in the restore tree (probably also a list all files)
1094 Do both a long and short form.
1095 - Allow browsing the catalog to see all versions of a file (with
1096 stat data on each file).
1097 - Restore attributes of directory if replace=never set but directory
1099 - Use SHA1 on authentication if possible.
1100 - See comtest-xxx.zip for Windows code to talk to USB.
1101 - Add John's appended files:
1102 Appended = { /files/server/logs/http/*log }
1103 and such files would be treated as follows.On a FULL backup, they would
1104 be backed up like any other file.On an INCREMENTAL backup, where a
1105 previous INCREMENTAL or FULL was already in thecatalogue and the length
1106 of the file wasgreater than the length of the last backup, only thedata
1107 added since the last backup will be dumped.On an INCREMENTAL backup, if
1108 the length of the file is less than thelength of the file with the same
1109 name last backed up, the completefile is dumped.On Windows systems, with
1110 creation date of files, we can be evensmarter about this and not count
1111 entirely upon the length.On a restore, the full and all incrementals
1112 since it will beapplied in sequence to restore the file.
1113 - Check new HAVE_WIN32 open bits.
1114 - Check if the tape has moved before writing.
1115 - Handling removable disks -- see below:
1116 - Keep track of tape use time, and report when cleaning is necessary.
1117 - Add FromClient and ToClient keywords on restore command (or
1118 BackupClient RestoreClient).
1119 - Implement a JobSet, which groups any number of jobs. If the
1120 JobSet is started, all the jobs are started together.
1121 Allow Pool, Level, and Schedule overrides.
1122 - Enhance cancel to timeout BSOCK packets after a specific delay.
1123 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1124 ua_status.!!! Thanks to Alan Brown for this tip.
1125 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1126 correctly for multiple simultaneous jobs.
1127 - Correct code so that FileSet MD5 is calculated for < and | filename
1129 - Implement the Media record flag that indicates that the Volume does disk
1131 - Implement VolAddr, which is used when Volume is addressed like a disk,
1132 and form it from VolFile and VolBlock.
1133 - Make multiple restore jobs for multiple media types specifying
1134 the proper storage type.
1135 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1136 pointer (rec) to try_repositioning().
1137 - Look at extracting Win data from BackupRead.
1138 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1139 which would take precidence over the Catalog "JobRetention".
1140 - Implement Label Format in Add and Label console commands.
1141 - Possibly up network buffers to 65K. Put on variable.
1142 - Put email tape request delays on one or more variables. User wants
1143 to cancel the job after a certain time interval. Maximum Mount Wait?
1144 - Job, Client, Device, Pool, or Volume?
1145 Is it possible to make this a directive which is *optional* in multiple
1146 resources, like Level? If so, I think I'd make it an optional directive
1147 in Job, Client, and Pool, with precedence such that Job overrides Client
1148 which in turn overrides Pool.
1150 - New Storage specifications:
1151 - Want to write to multiple storage devices simultaneously
1152 - Want to write to multiple storage devices sequentially (in one job)
1153 - Want to read/write simultaneously
1154 - Key is MediaType -- it must match
1156 Passed to SD as a sort of BSR record called Storage Specification
1160 MediaType -> Next MediaType
1162 Device -> Next Device
1164 Allow multiple Storage specifications
1172 Allow Multiple Pool specifications (note, Pool currently
1174 Allow Multiple MediaType specifications in Dir conf
1175 Allow Multiple Device specifications in Dir conf
1176 Perhaps keep this in a single SSR
1177 Tie a Volume to a specific device by using a MediaType that
1178 is contained in only one device.
1179 In SD allow Device to have Multiple MediaTypes
1181 - Ideas from Jerry Scharf:
1182 First let's point out some big pluses that bacula has for this
1184 more importantly it's active. Thank you so much for that
1185 even more important, it's not flaky
1186 it has an open access catalog, opening many possibilities
1187 it's pushing toward heterogeneous systems capability
1189 Macintosh file client
1190 macs are an interesting niche, but I fear a server is a rathole
1191 working bare iron recovery for windows
1192 the option for inc/diff backups not reset on fileset revision
1193 a) use both change and inode update time against base time
1194 b) do the full catalog check (expensive but accurate)
1195 sizing guide (how much system is needed to back up N systems/files)
1196 consultants on using bacula in building a disaster recovery system
1197 an integration guide
1198 or how to get at fancy things that one could do with bacula
1199 logwatch code for bacula logs (or similar)
1200 linux distro inclusion of bacula (brings good and bad, but necessary)
1201 win2k/XP server capability (icky but you asked)
1202 support for Oracle database ??
1204 - Look at adding SQL server and Exchange support for Windows.
1205 - Make dev->file and dev->block_num signed integers so that -1 can
1206 be an invalid value which happens with BSR.
1207 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1208 is needed to properly specify ranges.
1209 - Add progress of files/bytes to SD and FD.
1210 - Print warning message if FileId > 4 billion
1211 - do a "messages" before the first prompt in Console
1212 - Client does not show busy during Estimate command.
1213 - Implement Console mtx commands.
1214 - Implement a Mount Command and an Unmount Command where
1215 the users could specify a system command to be performed
1216 to do the mount, after which Bacula could attempt to
1217 read the device. This is for Removeable media such as a CDROM.
1218 - Most likely, this mount command would be invoked explicitly
1219 by the user using the current Console "mount" and "unmount"
1220 commands -- the Storage Daemon would do the right thing
1221 depending on the exact nature of the device.
1222 - As with tape drives, when Bacula wanted a new removable
1223 disk mounted, it would unmount the old one, and send a message
1224 to the user, who would then use "mount" as described above
1225 once he had actually inserted the disk.
1226 - Implement dump/print label to UA
1227 - Spool to disk only when the tape is full, then when a tape is hung move
1229 - bextract is sending everything to the log file ****FIXME****
1230 - Allow multiple Storage specifications (or multiple names on
1231 a single Storage specification) in the Job record. Thus a job
1232 can be backed up to a number of storage devices.
1233 - Implement some way for the File daemon to contact the Director
1234 to start a job or pass its DHCP obtained IP number.
1235 - Implement a query tape prompt/replace feature for a console
1236 - Copy console @ code to gnome2-console
1237 - Make sure that Bacula rechecks the tape after the 20 min wait.
1238 - Set IO_NOWAIT on Bacula TCP/IP packets.
1239 - Try doing a raw partition backup and restore by mounting a
1241 - From Lars Kellers:
1242 Yes, it would allow to highly automatic the request for new tapes. If a
1243 tape is empty, bacula reads the barcodes (native or simulated), and if
1244 an unused tape is found, it runs the label command with all the
1245 necessary parameters.
1247 By the way can bacula automatically "move" an empty/purged volume say
1248 in the "short" pool to the "long" pool if this pool runs out of volume
1250 - What to do about "list files job=xxx".
1251 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1252 file descriptor leak in Bacula.
1253 - Implement WrapCounters in Counters.
1254 - Add heartbeat from FD to SD if hb interval expires.
1255 - Can we dynamically change FileSets?
1256 - If pool specified to label command and Label Format is specified,
1257 automatically generate the Volume name.
1258 - Why can't SQL do the filename sort for restore?
1259 - Add ExhautiveRestoreSearch
1260 - Look at the possibility of loading only the necessary
1261 data into the restore tree (i.e. do it one directory at a
1262 time as the user walks through the tree).
1263 - Possibly use the hash code if the user selects all for a restore command.
1264 - Fix "restore all" to bypass building the tree.
1265 - Prohibit backing up archive device (findlib/find_one.c:128)
1266 - Implement Release Device in the Job resource to unmount a drive.
1267 - Implement Acquire Device in the Job resource to mount a drive,
1268 be sure this works with admin jobs so that the user can get
1269 prompted to insert the correct tape. Possibly some way to say to
1270 run the job but don't save the files.
1271 - Make things like list where a file is saved case independent for
1273 - Use autochanger to handle multiple devices.
1274 - Implement a Recycle command
1275 - Start working on Base jobs.
1276 - Implement UnsavedFiles DB record.
1277 - From Phil Stracchino:
1278 It would probably be a per-client option, and would be called
1279 something like, say, "Automatically purge obsoleted jobs". What it
1280 would do is, when you successfully complete a Differential backup of a
1281 client, it would automatically purge all Incremental backups for that
1282 client that are rendered redundant by that Differential. Likewise,
1283 when a Full backup on a client completed, it would automatically purge
1284 all Differential and Incremental jobs obsoleted by that Full backup.
1285 This would let people minimize the number of tapes they're keeping on
1286 hand without having to master the art of retention times.
1287 - When doing a Backup send all attributes back to the Director, who
1288 would then figure out what files have been deleted.
1289 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1290 explicit permission to do so. It should also mark the tape in error
1291 if there is an error.
1292 - Cancel waiting for Client connect in SD if FD goes away.
1294 - Implement timeout in response() when it should come quickly.
1295 - Implement a Slot priority (loaded/not loaded).
1296 - Implement "vacation" Incremental only saves.
1297 - Implement create "FileSet"?
1298 - Add prefixlinks to where or not where absolute links to FD.
1299 - Issue message to mount a new tape before the rewind.
1300 - Simplified client job initiation for portables.
1301 - If SD cannot open a drive, make it periodically retry.
1302 - Add more of the config info to the tape label.
1304 - Refine SD waiting output:
1305 Device is being positioned
1306 > Device is being positioned for append
1307 > Device is being positioned to file x
1309 - Figure out some way to estimate output size and to avoid splitting
1310 a backup across two Volumes -- this could be useful for writing CDROMs
1311 where you really prefer not to have it split -- not serious.
1312 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1313 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1314 actual data on the Volume and compare it.
1315 - Make bcopy read through bad tape records.
1316 - Program files (i.e. execute a program to read/write files).
1317 Pass read date of last backup, size of file last time.
1318 - Add Signature type to File DB record.
1319 - CD into subdirectory when open()ing files for backup to
1320 speed up things. Test with testfind().
1321 - Priority job to go to top of list.
1322 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1323 - Implement some way for the Console to dynamically create a job.
1324 - Solaris -I on tar for include list
1325 - Need a verbose mode in restore, perhaps to bsr.
1326 - bscan without -v is too quiet -- perhaps show jobs.
1327 - Add code to reject whole blocks if not wanted on restore.
1328 - Check if we can increase Bacula FD priorty in Win2000
1329 - Make sure the MaxVolFiles is fully implemented in SD
1330 - Check if both CatalogFiles and UseCatalog are set to SD.
1331 - Possibly add email to Watchdog if drive is unmounted too
1332 long and a job is waiting on the drive.
1333 - After unmount, if restore job started, ask to mount.
1334 - Add UA rc and history files.
1335 - put termcap (used by console) in ./configure and
1336 allow -with-termcap-dir.
1337 - Fix Autoprune for Volumes to respect need for full save.
1338 - Compare tape to Client files (attributes, or attributes and data)
1339 - Make all database Ids 64 bit.
1340 - Allow console commands to detach or run in background.
1341 - Add SD message variables to control operator wait time
1342 - Maximum Operator Wait
1343 - Minimum Message Interval
1344 - Maximum Message Interval
1345 - Send Operator message when cannot read tape label.
1346 - Verify level=Volume (scan only), level=Data (compare of data to file).
1347 Verify level=Catalog, level=InitCatalog
1349 - Add keyword search to show command in Console.
1350 - Events : tape has more than xxx bytes.
1351 - Complete code in Bacula Resources -- this will permit
1352 reading a new config file at any time.
1353 - Handle ctl-c in Console
1354 - Implement script driven addition of File daemon to config files.
1355 - Think about how to make Bacula work better with File (non-tape) archives.
1356 - Write Unix emulator for Windows.
1357 - Put memory utilization in Status output of each daemon
1358 if full status requested or if some level of debug on.
1359 - Make database type selectable by .conf files i.e. at runtime
1360 - Set flag for uname -a. Add to Volume label.
1361 - Restore files modified after date
1362 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1363 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1364 - Timout a job or terminate if link goes down, or reopen link and query.
1365 - Concept of precious tapes (cannot be reused).
1366 - Make bcopy copy with a single tape drive.
1367 - Permit changing ownership during restore.

1381 - Autolabel should be specified by DIR instead of SD.
1383 - Add media capacity
1384 - AutoScan (check checksum of tape)
1385 - Format command = "format /dev/nst0"
1389 - Seek resolution (usually corresponds to buffer size)
1390 - EODErrorCode=ENOSPC or code
1391 - Partial Read error code
1392 - Partial write error code
1393 - Nonformatted read error
1394 - Nonformatted write error
1395 - WriteProtected error
1399 - IgnoreCloseErrors=yes
1409 - FD sends unsaved file list to Director at end of job (see
1411 - File daemon should build list of files skipped, and then
1412 at end of save retry and report any errors.
1413 - Write a Storage daemon that uses pipes and
1414 standard Unix programs to write to the tape.
1416 - Need something that monitors the JCR queue and
1417 times out jobs by asking the deamons where they are.
1418 - Enhance Jmsg code to permit buffering and saving to disk.
1419 - device driver = "xxxx" for drives.
1420 - Verify from Volume
1421 - Ensure that /dev/null works
1422 - Need report class for messages. Perhaps
1423 report resource where report=group of messages
1424 - enhance scan_attrib and rename scan_jobtype, and
1425 fill in code for "since" option
1426 - Director needs a time after which the report status is sent
1427 anyway -- or better yet, a retry time for the job.
1428 - Don't reschedule a job if previous incarnation is still running.
1429 - Some way to automatically backup everything is needed????
1430 - Need a structure for pending actions:
1432 - termination status (part of buffered msgs?)
1434 Read, Write, Clean, Delete
1435 - Login to Bacula; Bacula users with different permissions:
1436 owner, group, user, quotas
1437 - Store info on each file system type (probably in the job header on tape.
1438 This could be the output of df; or perhaps some sort of /etc/mtab record.
1440 ========= ideas ===============
1441 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1442 To: <kern@sibbald.com>
1443 Subject: RE: [Bacula-users] future large programming jobs
1444 Date: Thu, 26 Feb 2004 11:34:54 -0600
1446 I noticed the subject thread and thought I would offer the following
1447 merely as sources of ideas, i.e. something to think about, not even as
1448 strong as a request. In my former life (before retiring) I often
1449 dealt with backups and storage management issues/products as a
1450 developer and as a consultant. I am currently migrating my personal
1451 network from amanda to bacula specifically because of the ability to
1452 cross media boundaries during storing backups.
1453 Are you familiar with the commercial product called ADSM (I think IBM
1454 now sells it under the Tivoli label)? It has a couple of interesting
1455 ideas that may apply to the following topics.
1457 1. Migration: Consider that when you need to restore a system, there
1458 may be pressure to hurry. If all the information for a single client
1459 can eventually end up on the same media (and in chronological order),
1460 the restore is facillitated by not having to search past information
1461 from other clients. ADSM has the concept of "client affinity" that
1462 may be associated with it's storage pools. It seems to me that this
1463 concept (as an optional feature) might fit in your architecture for
1466 ADSM also has the concept of defining one or more storage pools as
1467 "copy pools" (almost mirrors, but only in the sense of contents).
1468 These pools provide the ability to have duplicte data stored both
1469 onsite and offsite. The copy process can be scheduled to be handled
1470 by their storage manager during periods when there is no backup
1471 activity. Again, the migration process might be a place to consider
1472 implementing something like this.
1475 > It strikes me that it would be very nice to be able to do things
1477 > have the Job(s) backing up the machines run, and once they have all

1483 > mechanism described below would probably make it very easy.
1485 This is the goal. In the first step (before events), you simply
1487 the Migration to tape later.
1489 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1490 the database. Once a file (unique by path and metadata such as dates,
1491 size, ownership, etc.) is in a copy pool, no more copies are made. In
1492 other words, when you start ADSM, it begins like your concept of a
1493 base job. After that it is in the "incremental" mode. You can
1494 configure the number of "generations" of files to be retained, plus a
1495 retention date after which even old generations are purged. The
1496 database tracks the contents of media and projects the percentage of
1497 each volume that is valid. When the valid content of a volume drops
1498 below a configured percentage, the valid data are migrated to another
1499 volume and the old volume is marked as empty. Note, this requires
1500 ADSM to have an idea of the contents of a client, i.e. marking the
1501 database when an existing file was deleted, but this would solve your
1502 issue of restoring a client without restoring deleted files.
1504 This is pretty far from what bacula now does, but if you are going to
1505 rip things up for Base jobs,.....
1506 Also, the benefits of this are huge for very large shops, especially
1507 with media robots, but are a pain for shops with manual media
1511 > Base jobs sound pretty useful, but I'm not dying for them.
1513 Nobody is dying for them, but when you see what it does, you will die
1516 3. Restoring deleted files: Since I think my comments in (2) above
1517 have low probability of implementation, I'll also suggest that you
1518 could approach the issue of deleted files by a mechanism of having the
1519 fd report to the dir, a list of all files on the client for every
1520 backup job. The dir could note in the database entry for each file
1521 the date that the file was seen. Then if a restore as of date X takes
1522 place, only files that exist from before X until after X would be
1523 restored. Probably the major cost here is the extra date container in
1524 each row of the files table.
1526 Thanks for "listening". I hope some of this helps. If you want to
1527 contact me, please send me an email - I read some but not all of the
1528 mailing list traffic and might miss a reply there.
1530 Please accept my compliments for bacula. It is doing a great job for
1531 me!! I sympathize with you in the need to wrestle with excelence in
1532 execution vs. excelence in feature inclusion.
1537 ==============================
1540 - Design at hierarchial storage for Bacula. Migration and Clone.
1541 - Implement FSM (File System Modules).
1542 - Audit M_ error codes to ensure they are correct and consistent.
1543 - Add variable break characters to lex analyzer.
1544 Either a bit mask or a string of chars so that
1545 the caller can change the break characters.
1546 - Make a single T_BREAK to replace T_COMMA, etc.
1547 - Ensure that File daemon and Storage daemon can
1548 continue a save if the Director goes down (this
1549 is NOT currently the case). Must detect socket error,
1550 buffer messages for later.
1551 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1552 - Add ability to backup to two Storage devices (two SD sessions) at
1553 the same time -- e.g. onsite, offsite.
1554 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1555 someway to do so with every volume that has less than x% valid
1559 Migration: Move a backup from one Volume to another
1560 Clone: Copy a backup -- two Volumes
1563 ======================================================
1565 It is somewhat like a Full save becomes an incremental since
1566 the Base job (or jobs) plus other non-base files.
1568 - A Base backup is same as Full backup, just different type.
1569 - New BaseFiles table that contains:
1571 BaseJobId - Base JobId referenced for this FileId (needed ???)
1572 JobId - JobId currently running
1573 FileId - File not backed up, exists in Base Job
1574 FileIndex - FileIndex from Base Job.
1575 i.e. for each base file that exists but is not saved because
1576 it has not changed, the File daemon sends the JobId, BaseId,
1577 FileId, FileIndex back to the Director who creates the DB entry.
1578 - To initiate a Base save, the Director sends the FD
1579 the FileId, and full filename for each file in the Base.
1580 - When the FD finds a Base file, he requests the Director to
1581 send him the full File entry (stat packet plus MD5), or
1582 conversely, the FD sends it to the Director and the Director
1583 says yes or no. This can be quite rapid if the FileId is kept
1584 by the FD for each Base Filename.
1585 - It is probably better to have the comparison done by the FD
1586 despite the fact that the File entry must be sent across the
1588 - An alternative would be to send the FD the whole File entry
1589 from the start. The disadvantage is that it requires a lot of
1590 space. The advantage is that it requires less communications
1592 - The Job record must be updated to indicate that one or more
1594 - At end of Job, FD returns:
1595 1. Count of base files/bytes not written to tape (i.e. matches)
1596 2. Count of base file that were saved i.e. had changed.
1597 - No tape record would be written for a Base file that matches, in the
1598 same way that no tape record is written for Incremental jobs where
1599 the file is not saved because it is unchanged.
1600 - On a restore, all the Base file records must explicitly be
1601 found from the BaseFile tape. I.e. for each Full save that is marked
1602 to have one or more Base Jobs, search the BaseFile for all occurrences
1604 - An optimization might be to make the BaseFile have:
1610 This would avoid the need to explicitly fetch each File record for
1611 the Base job. The Base Job record will be fetched to get the
1612 VolSessionId and VolSessionTime.

1655 (just to verify it remembers where it came from, however it can be

1658 There needs to be a table of drive # to devices somewhere - If there are
1659 multiple changers or drives there may not be a 1:1 correspondance between
1660 changer drive number and system device name - and depending on the way the
1661 drives are hooked up to scsi busses, they may not be linearly numbered
1662 from an offset point either.something like
1664 Autochanger drives = 2
1665 Autochanger drive 0 = /dev/nst1
1666 Autochanger drive 1 = /dev/nst2
1667 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1668 times, not just for multidrive changers. For a 1 drive changer, that's
1674 MTX's manpage (1.2.15):
1675 unload [<slotnum>] [ <drivenum> ]
1676 Unloads media from drive <drivenum> into slot
1677 <slotnum>. If <drivenum> is omitted, defaults to
1678 drive 0 (as do all commands). If <slotnum> is

1721 Handling removable disks
1723 From: Karl Cunningham <karlc@keckec.com>
1725 My backups are only to hard disk these days, in removable bays. This is my
1726 idea of how a backup to hard disk would work more smoothly. Some of these
1727 things Bacula does already, but I mention them for completeness. If others
1728 have better ways to do this, I'd like to hear about it.
1730 1. Accommodate several disks, rotated similar to how tapes are. Identified
1731 by partition volume ID or perhaps by the name of a subdirectory.
1732 2. Abort & notify the admin if the wrong disk is in the bay.
1733 3. Write backups to different subdirectories for each machine to be backed
1735 4. Volumes (files) get created as needed in the proper subdirectory, one
1737 5. When a disk is recycled, remove or zero all old backup files. This is
1738 important as the disk being recycled may be close to full. This may be
1739 better done manually since the backup files for many machines may be
1740 scattered in many subdirectories.
1745 - Why the heck doesn't bacula drop root priviledges before connecting to
1747 - Look at using posix_fadvise(2) for backups -- see bug #751.
1748 Possibly add the code at findlib/bfile.c:795
1749 /* TCP socket options */
1750 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1751 - Fix bnet_connect() code to set a timer and to use time to
1753 - Implement 4th argument to make_catalog_backup that passes hostname.
1754 - Test FIFO backup/restore -- make regression
1755 - Please mount volume "xxx" on Storage device ... should also list
1756 Pool and MediaType in case user needs to create a new volume.
1757 - On restore add Restore Client, Original Client.

1766 - Check if gnome-console works with TLS.
1767 - the director seg faulted when I omitted the pool directive from a
1768 job resource. I was experimenting and thought it redundant that I had
1769 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1770 apparently not. This happened when I removed the pool directive and
1771 started the director.
1772 - Add Where: client:/.... to restore job report.
1773 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1774 does the right thing.
1775 - FD-SD quick disconnect
1776 - Building the in memory restore tree is slow.
1777 - Erabt if min_block_size > max_block_size
1778 - Add the ability to consolidate old backup sets (basically do a restore
1779 to tape and appropriately update the catalog). Compress Volume sets.
1780 Might need to spool via file is only one drive is available.
1781 - Why doesn't @"xxx abc" work in a conf file?
1782 - Don't restore Solaris Door files:
1783 #define S_IFDOOR in st_mode.
1784 see: http://docs.sun.com/app/docs/doc/816-5173/6mbb8ae23?a=view#indexterm-360
1785 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
1786 - Implement Despooling data status.
1787 - Use E'xxx' to escape PostgreSQL strings.
1788 - Look at mincore: http://insights.oetiker.ch/linux/fadvise.html
1789 - Unicode input http://en.wikipedia.org/wiki/Byte_Order_Mark
1790 - Look at moving the Storage directive from the Job to the
1791 Pool in the default conf files.
1792 - Look at in src/filed/backup.c
1793 > pm_strcpy(ff_pkt->fname, ff_pkt->fname_save);
1794 > pm_strcpy(ff_pkt->link, ff_pkt->link_save);
1795 - Add Catalog = to Pool resource so that pools will exist
1796 in only one catalog -- currently Pools are "global".
1797 - Add TLS to bat (should be done).
1798 === Duplicate jobs ===
1799 hese apply only to backup jobs.
1801 1. Allow Duplicate Jobs = Yes | No | Higher (Yes)
1803 2. Duplicate Job Interval = <time-interval> (0)
1805 The defaults are in parenthesis and would produce the same behavior as today.
1807 If Allow Duplicate Jobs is set to No, then any job starting while a job of the
1808 same name is running will be canceled.
1810 If Allow Duplicate Jobs is set to Higher, then any job starting with the same
1811 or lower level will be canceled, but any job with a Higher level will start.
1812 The Levels are from High to Low: Full, Differential, Incremental
1814 Finally, if you have Duplicate Job Interval set to a non-zero value, any job
1815 of the same name which starts <time-interval> after a previous job of the
1816 same name would run, any one that starts within <time-interval> would be
1817 subject to the above rules. Another way of looking at it is that the Allow
1818 Duplicate Jobs directive will only apply after <time-interval> of when the
1819 previous job finished (i.e. it is the minimum interval between jobs).
1823 Allow Duplicate Jobs = Yes | No | HigherLevel | CancelLowerLevel (Yes)
1825 Where HigherLevel cancels any waiting job but not any running job.
1826 Where CancelLowerLevel is same as HigherLevel but cancels any running job or
1829 Duplicate Job Proximity = <time-interval> (0)
1831 My suggestion was to define it as the minimum guard time between
1832 executions of a specific job -- ie, if a job was scheduled within Job
1833 Proximity number of seconds, it would be considered a duplicate and
1836 Skip = Do not allow two or more jobs with the same name to run
1837 simultaneously within the proximity interval. The second and subsequent
1838 jobs are skipped without further processing (other than to note the job
1839 and exit immediately), and are not considered errors.
1841 Fail = The second and subsequent jobs that attempt to run during the
1842 proximity interval are cancelled and treated as error-terminated jobs.
1844 Promote = If a job is running, and a second/subsequent job of higher
1845 level attempts to start, the running job is promoted to the higher level
1846 of processing using the resources already allocated, and the subsequent
1847 job is treated as in Skip above.
1853 Allow = yes|no (no = default)
1855 AllowHigherLevel = yes|no (no)
1857 AllowLowerLevel = yes|no (no)
1859 AllowSameLevel = yes|no
1861 Cancel = Running | New (no)
1863 CancelledStatus = Fail | Skip (fail)
1865 Job Proximity = <time-interval> (0)
1866 My suggestion was to define it as the minimum guard time between
1867 executions of a specific job -- ie, if a job was scheduled within Job
1868 Proximity number of seconds, it would be considered a duplicate and
