6 - This patch will give Bacula the option to specify files in
7 FileSets which can be dropped in directories which are Included
8 which will cause that directory not the be backed up.
10 For example, my FileSet contains:
11 # List of files to be backed up
13 Name = "Remote Specified1"
18 File = "\\</etc/bacula-include"
19 IgnoreDir = .notthisone
22 File = "\\</etc/bacula-exclude"
26 And /etc/bacula-include contains:
30 But in /home, there are hundreds of directories of users and some
31 people want to indicate that they don't want to have certain
32 directories backed-up:
37 So I can put them in /etc/bacula-exclude, but that is a system
38 file and not editable for mortal users. To make it possible for
39 users to make it clear to the system that certain directories
40 don't need to be backed up, they now can create file called
43 /home/edwin/www/cache/.notthisone
44 /home/edwin/temp/.notthisone
46 so that the backup system will be clear of rubbish like stuff in
47 these two directories but still that I as administrator of the
48 system don't have to be involved in it.
49 - !!! Cannot restore two jobs a the same time that were
50 written simultaneously unless they were totally spooled.
51 - Document cleaning up the spool files:
52 db, pid, state, bsr, mail, conmsg, spool
53 - Document the multiple-drive-changer.txt script.
54 - Pruning with Admin job.
55 - Does WildFile match against full name? Doc.
56 - %d and %v only valid on Director, not for ClientRunBefore/After.
57 - During tests with the 260 char fix code, I found one problem:
58 if the system "sees" a long path once, it seems to forget it's
59 working drive (e.g. c:\), which will lead to a problem during
60 the next job (create bootstrap file will fail). Here is the
61 workaround: specify absolute working and pid directory in
62 bacula-fd.conf (e.g. c:\bacula\working instead of
64 - Document techniques for restoring large numbers of files.
65 - Document setting my.cnf to big file usage.
66 - Add example of proper index output to doc. show index from File;
67 - Correct the Include syntax in the m4.xxx files in examples/conf
68 - Document JobStatus and Termination codes.
69 - Fix the error with the "DVI file can't be opened" while
70 building the French PDF.
71 - Document more DVD stuff
79 - Document all the little details of setting up certificates for
80 the Bacula data encryption code.
81 - Document more precisely how to use master keys -- especially
82 for disaster recovery.
85 - Migration from other vendors

112 - Look at: http://tech.groups.yahoo.com/group/cfg2html
113 and http://www.openeyet.nl/scc/ for managing customer changes
117 - Change calling sequence to delete_job_id_range() in ua_cmds.c
118 the preceding strtok() is done inside the subroutine only once.
119 - Dangling softlinks are not restored properly. For example, take a
120 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
121 move the directory to another machine where the file /usr/share/autoconf does
122 not exist, back it up, then try a full restore. It fails.
123 - Check for FD compatibility -- eg .nobackup ...
124 - Re-check new dcr->reserved_volume
125 - Softlinks that point to non-existent file are not restored in restore all,
126 but are restored if the file is individually selected. BUG!
127 - Doc Duplicate Jobs.
128 - New directive "Delete purged Volumes"
130 - Prune by Job Level (Full, Differential, Incremental)
131 - Strict automatic pruning
132 - Implement unmount of USB volumes.
133 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
134 Win32 to avoid patent problems.
135 - Implement multiple jobid specification for the cancel command,
136 similar to what is permitted on the update slots command.
137 - Implement Bacula plugins -- design API
138 - modify pruning to keep a fixed number of versions of a file,
140 - the cd-command should allow complete paths
141 i.e. cd /foo/bar/foo/bar
142 -> if a customer mails me the path to a certain file,
143 its faster to enter the specified directory
144 - Make tree walk routines like cd, ls, ... more user friendly
145 by handling spaces better.
149 MA = (last_MA * 3 + rate) / 4
150 rate = (bytes - last_bytes) / (runtime - last_runtime)
151 - Add a recursive mark command (rmark) to restore.
152 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
153 of the same level and does not permit multiple simultaneous
154 running of that Job (i.e. lets any previous invocation finish
155 before doing Interval testing).
156 - Look at simplifying File exclusions.
158 - Auto update of slot:
159 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
160 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

164 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
165 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)

168 - Eliminate: /var is a different filesystem. Will not descend from / into /var
169 - Separate Files and Directories in catalog
170 - Create FileVersions table
171 - Look at rsysnc for incremental updates and dedupping
172 - Add MD5 or SHA1 check in SD for data validation
173 - finish implementation of fdcalled -- see ua_run.c:105
174 - Fix problem in postgresql.c in my_postgresql_query, where the
175 generation of the error message doesn't differentiate result==NULL
176 and a bad status from that result. Not only that, the result is
177 cleared on a bail_out without having generated the error message.
179 - Implement SDErrors (must return from SD)
180 - Implement USB keyboard support in rescue CD.
181 - Implement continue spooling while despooling.
182 - Remove all install temp files in Win32 PLUGINSDIR.
183 - Audit retention periods to make sure everything is 64 bit.
184 - No where in restore causes kaboom.
185 - Performance: multiple spool files for a single job.
186 - Performance: despool attributes when despooling data (problem
187 multiplexing Dir connection).
188 - Make restore use the in-use volume reservation algorithm.
189 - When Pool specifies Storage command override does not work.
190 - Implement wait_for_sysop() message display in wait_for_device(), which
191 now prints warnings too often.
192 - Ensure that each device in an Autochanger has a different
194 - Look at sg_logs -a /dev/sg0 for getting soft errors.
195 - btape "test" command with Offline on Unmount = yes
197 This test is essential to Bacula.
199 I'm going to write one record in file 0,
200 two records in file 1,
201 and three records in file 2

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

216 - Figure out some way to "automatically" backup conf changes.
217 - Add the OS version back to the Win32 client info.
218 - Restarted jobs have a NULL in the from field.
219 - Modify SD status command to indicate when the SD is writing
220 to a DVD (the device is not open -- see bug #732).
221 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
222 and possibly changing the blobs into varchar.
223 - Ensure that the SD re-reads the Media record if the JobFiles
224 does not match -- it may have been updated by another job.
226 - Test Volume compatibility between machine architectures
227 - Encryption documentation
228 - Wrong jobbytes with query 12 (todo)
229 - Bare-metal recovery Windows (todo)
234 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
236 - Maximum number of scratch volumes
238 - Next Pool (already have)
239 - Reclamation threshold
241 - Reuse delay (after all files purged from volume before it can be used)
242 - Copy Pool = xx, yyy (or multiple lines).
244 - Allow pool selection during restore.
246 - Average tape size from Eric
247 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
248 count(Media.MediaId) AS volnum,
249 sum(Media.VolBytes) AS voltotal,
250 Media.PoolId AS PoolId,
251 Media.MediaType AS MediaType
253 LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,
254 Media.MediaType AS MediaType
256 WHERE Media.VolStatus = 'Full'
257 GROUP BY Media.MediaType
258 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
259 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
263 - Add doc for bweb -- especially Installation
265 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
267 - Despool attributes in separate thread
270 - Check why restore repeatedly sends Rechdrs between
271 each data chunk -- according to James Harper 9Jan07.
274 - Full at least once a month, ...
275 - Cancel Inc if Diff/Full running
276 - More intelligent re-run
277 - New/deleted file backup
279 - Incremental backup -- rsync, Stow
283 - Try to fix bscan not working with multiple DVD volumes bug #912.
284 - Look at mondo/mindi
285 - Make Bacula by default not backup tmpfs, procfs, sysfs, ...
286 - Fix hardlinked immutable files when linking a second file, the
287 immutable flag must be removed prior to trying to link it.
288 - Implement Python event for backing up/restoring a file.
289 - Change dbcheck to tell users to use native tools for fixing
290 broken databases, and to ensure they have the proper indexes.
291 - add udev rules for Bacula devices.
292 - If a job terminates, the DIR connection can close before the
293 Volume info is updated, leaving the File count wrong.
294 - Look at why SIGPIPE during connection can cause seg fault in
295 writing the daemon message, when Dir dropped to bacula:bacula
296 - Look at zlib 32 => 64 problems.
297 - Possibly turn on St. Bernard code.
298 - Fix bextract to restore ACLs, or better yet, use common routines.
299 - Do we migrate appendable Volumes?
300 - Remove queue.c code.
301 - Print warning message if LANG environment variable does not specify
303 - New dot commands from Arno.
304 .show device=xxx lists information from one storage device, including
305 devices (I'm not even sure that information exists in the DIR...)
306 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
307 better machine-readable output like "Ok" or "Error busy"
308 .move eject device=xxx toslot=yyy the same as above, but with a new
309 target slot. The catalog should be updated accordingly.
310 .move transfer device=xxx fromslot=yyy toslot=zzz

340 - Possibly allow SD to spool even if a tape is not mounted.
341 - Fix re-read of last block to check if job has actually written
342 a block, and check if block was written by a different job
343 (i.e. multiple simultaneous jobs writing).
344 - Figure out how to configure query.sql. Suggestion to use m4:
345 == changequote.m4 ===
346 changequote(`[',`]')dnl
347 ==== query.sql.in ===
348 :List next 20 volumes to expire
350 Pool.Name AS PoolName,
355 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
357 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
361 ON Media.PoolId=Pool.PoolId
362 WHERE Media.LastWritten>0
366 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
368 The problem is that it requires m4, which is not present on all machines
370 - Given all the problems with FIFOs, I think the solution is to do something a
371 little different, though I will look at the code and see if there is not some
372 simple solution (i.e. some bug that was introduced). What might be a better
373 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
374 write data to a program rather than the FIFO. For example, suppose you
379 Then, I could imagine if you backup and restore this file with a direct
380 reference as is currently done for fifos, instead, during backup Bacula will
383 /home/kern/my-fifo.backup
385 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
388 /home/kern/my-fifo.restore
390 and send the data backed up to stdout. These programs can either be an
391 executable or a shell script and they need only read/write to stdin/stdout.
393 I think this would give a lot of flexibility to the user without making any
394 significant changes to Bacula.
399 select FilenameId from Filename where Name='';

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

531 - Directive: at <event> "command"
532 - Command: pycmd "command" generates "command" event. How to
533 attach to a specific job?
534 - Integrate Christopher's St. Bernard code.
535 - run_cmd() returns int should return JobId_t
536 - get_next_jobid_from_list() returns int should return JobId_t
537 - Document export LDFLAGS=-L/usr/lib64
538 - Don't attempt to restore from "Disabled" Volumes.
539 - Network error on Win32 should set Win32 error code.
540 - What happens when you rename a Disk Volume?
541 - Job retention period in a Pool (and hence Volume). The job would
543 - Look at -D_FORTIFY_SOURCE=2
544 - Add Win32 FileSet definition somewhere
545 - Look at fixing restore status stats in SD.
546 - Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
547 http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
548 - Implement a mode that says when a hard read error is
549 encountered, read many times (as it currently does), and if the
550 block cannot be read, skip to the next block, and try again. If
551 that fails, skip to the next file and try again, ...
553 create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
554 insert into LevelType (LevelType,LevelTypeLong) values
558 - Show files/second in client status output.
559 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
560 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
561 see if it become stable and I just have to supervise
563 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
564 PoolId, and when it is empty remove it.
566 - Allow Check Labels to be used with Bacula labels.
567 - "Resuming" a failed backup (lost line for example) by using the
568 failed backup as a sort of "base" job.
570 - Email to the user when the tape is about to need changing x
571 days before it needs changing.
572 - Command to show next tape that will be used for a job even
573 if the job is not scheduled.

575 1. When jobs are running and bacula for some reason crashes or if I do a
576 restart it remembers and jobs it was running before it crashed or restarted
577 as of now I loose all jobs if I restart it.
579 2. When spooling and in the midway if client is disconnected for instance a
580 laptop bacula completely discard the spool. It will be nice if it can write
581 that spool to tape so there will be some backups for that client if not all.
583 3. We have around 150 clients machines it will be nice to have a option to
584 upgrade all the client machines bacula version automatically.
586 4. Atleast one connection should be reserved for the bconsole so at heavy load
587 I should connect to the director via bconsole which at sometimes I can't
589 5. Another most important feature that is missing, say at 10am I manually
590 started backup of client abc and it was a full backup since client abc has
591 no backup history and at 10.30am bacula again automatically started backup of
592 client abc as that was in the schedule. So now we have 2 multiple Full
593 backups of the same client and if we again try to start a full backup of
594 client backup abc bacula won't complain. That should be fixed.
596 - For Windows disaster recovery see http://unattended.sf.net/
597 - regardless of the retention period, Bacula will not prune the
598 last Full, Diff, or Inc File data until a month after the
599 retention period for the last Full backup that was done.
600 - update volume=xxx --- add status=Full
601 - Remove old spool files on startup.
602 - Exclude SD spool/working directory.
603 - Refuse to prune last valid Full backup. Same goes for Catalog.
605 - Make a callback when Rerun failed levels is called.
606 - Give Python program access to Scheduled jobs.
607 - Add setting Volume State via Python.
608 - Python script to save with Python, not save, save with Bacula.
609 - Python script to do backup.
611 - Change the Priority, Client, Storage, JobStatus (error)
612 at the start of a job.
613 - Why is SpoolDirectory = /home/bacula/spool; not reported
614 as an error when writing a DVD?
615 - Make bootstrap file handle multiple MediaTypes (SD)
616 - Remove all old Device resource code in Dir and code to pass it
617 back in SD -- better, rework it to pass back device statistics.
618 - Check locking of resources -- be sure to lock devices where previously
619 resources were locked.
620 - The last part is left in the spool dir.
623 - In restore don't compare byte count on a raw device -- directory
624 entry does not contain bytes.
627 - Max Vols limit in Pool off by one?
628 - Implement Files/Bytes,... stats for restore job.
629 - Implement Total Bytes Written, ... for restore job.
630 - Despool attributes simultaneously with data in a separate
631 thread, rejoined at end of data spooling.
632 - 7. Implement new Console commands to allow offlining/reserving drives,
633 and possibly manipulating the autochanger (much asked for).
634 - Add start/end date editing in messages (%t %T, %e?) ...
635 - Add ClientDefs similar to JobDefs.
636 - Print more info when bextract -p accepts a bad block.
637 - Fix FD JobType to be set before RunBeforeJob in FD.
638 - Look at adding full Volume and Pool information to a Volume
639 label so that bscan can get *all* the info.
640 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
641 and there is only one volume in the pool, refuse to do it -- otherwise
642 he fills the Volume, then immediately starts reusing it.
643 - Implement copies and stripes.
644 - Add history file to console.
645 - Each file on tape creates a JobMedia record. Peter has 4 million
646 files spread over 10000 tape files and four tapes. A restore takes
647 16 hours to build the restore list.
648 - Add and option to check if the file size changed during backup.
649 - Make sure SD deletes spool files on error exit.
650 - Delete old spool files when SD starts.
651 - When labeling tapes, if you enter 000026, Bacula uses
652 the tape index rather than the Volume name 000026.
653 - Add offline tape command to Bacula console.
655 Enter MediaId or Volume name: 32
656 Enter new Volume name: DLT-20Dec04
657 Automatically selected Pool: Default
658 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

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

884 Media Type Write = LTO2, LTO3
886 === From Carsten Menke <bootsy52@gmx.net>
888 Following is a list of what I think in the situations where I'm faced with,
889 could be a usefull enhancement to bacula, which I'm certain other users will
890 benefit from as well.
892 1. NextJob/NextJobs Directive within a Job Resource in the form of
893 NextJobs = job1,job2.
896 I currently solved the problem with running multiple jobs each after each
897 by setting the Max Wait Time for a job to 8 hours, and give
898 the jobs different Priorities. However, there scenarios where
899 1 Job is directly depending on another job, so if the former job fails,
900 the job after it needn't to be run
901 while maybe other jobs should run despite of that
904 A Backup Job and a Verify job, if the backup job fails there is no need to run
905 the verify job, as the backup job already failed. However, one may like
906 to backup the Catalog to disk despite of that the main backup job failed.
909 I see that this is related to the Event Handlers which are on the ToDo
910 list, also it is maybe a good idea to check for the return value and
911 execute different actions based on the return value
914 3. offline capability to bconsole
917 Currently I use a script which I execute within the last Job via the
918 RunAfterJob Directive, to release and eject the tape.
919 So I have to call bconsole "release=Storage-Name" and afterwards
920 mt -f /dev/nst0 eject to get the tape out.
922 If I have multiple Storage Devices, than these may not be /dev/nst0 and
923 I have to modify the script or call it with parameters etc.
924 This would actually not be needed, as everything is already defined
925 in bacula-sd.conf and if I can invoke bconsole with the
926 storage name via $1 in the script than I'm done and information is
929 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
933 For the reason mentioned in 3. to have the ability to call a
934 script with /scripts/foobar %s and in the script use $1
935 to pass the Storage Name to bconsole
937 5. Setting Volume State within a Job Resource
940 Instead of using "Maximum Volume Jobs" in the Pool Resource,
941 I would have the possibilty to define
942 in a Job Resource that after this certain job is run, the Volume State
943 should be set to "Volume State = Used", this give more flexibility (IMHO).
945 6. Localization of Bacula Messages
948 Unfortunatley many,many people I work with don't speak english very well.
949 So if at least the Reporting messages would be localized then they
950 would understand that they have to change the tape,etc. etc.
952 I volunteer to do the german translations, and if I can convince my wife also
953 french and Morre (western african language).
955 7. OK, this is evil, probably bound to security risks and maybe not possible
956 due to the design of bacula.
958 Implementation of Backtics ( `command` ) for shell comand execution to
959 the "Label Format" Directive.
963 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
964 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
965 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
966 the localized name for the day of the week appended to the
967 format string. Then I have the tape labeled automatically with weekday
968 name in the correct language.
970 - Make output from status use html table tags for nicely
971 presenting in a browser.
972 - Can one write tapes faster with 8192 byte block sizes?
973 - Document security problems with the same password for everyone in
974 rpm and Win32 releases.
975 - Browse generations of files.
976 - I've seen an error when my catalog's File table fills up. I
977 then have to recreate the File table with a larger maximum row
978 size. Relevant information is at
979 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
980 "Installing and Configuring MySQL" chapter should talk a bit
981 about this potential problem, and recommend a solution.
982 - For Solaris must use POSIX awk.
983 - Want speed of writing to tape while despooling.
984 - Supported autochanger:
992 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
993 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
994 - Add regex from http://www.pcre.org to Bacula for Win32.
995 - Use only shell tools no make in CDROM package.
996 - Include within include does it work?
997 - Implement a Pool of type Cleaning?
998 - Implement VolReadTime and VolWriteTime in SD
999 - Modify Backing up Your Database to include a bootstrap file.
1000 - Think about making certain database errors fatal.
1001 - Look at correcting the time jump in the scheduler for daylight
1002 savings time changes.
1003 - Add a "real" timer to network connections.
1004 - Promote to Full = Time period
1005 - Check dates entered by user for correctness (month/day/... ranges)
1006 - Compress restore Volume listing by date and first file.
1007 - Look at patches/bacula_db.b2z postgresql that loops during restore.
1009 - Perhaps add read/write programs and/or plugins to FileSets.
1010 - How to handle backing up portables ...
1011 - Add some sort of guaranteed Interval for upgrading jobs.
1012 - Can we write the state file after every job terminates? On Win32
1013 the system crashes and the state file is not updated.
1016 Documentation to do: (any release a little bit at a time)
1017 - Doc to do unmount before removing magazine.
1018 - Alternative to static linking "ldd prog" save all binaries listed,
1019 restore them and point LD_LIBRARY_PATH to them.
1020 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
1021 - Document query file format.
1022 - Add more documentation for bsr files.
1023 - Document problems with Verify and pruning.
1024 - Document how to use multiple databases.
1025 - VXA drives have a "cleaning required"
1026 indicator, but Exabyte recommends preventive cleaning after every 75
1029 In this context, it should be noted that Exabyte has a command-line
1030 vxatool utility available for free download. (The current version is
1031 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
1032 test the drive, unload tapes, change drive settings, flash new firmware,
1034 Of particular interest in this context is that vxatool <device> -i will
1035 report, among other details, the time since last cleaning in tape motion
1036 minutes. This information can be retrieved (and settings changed, for
1037 that matter) through the generic-SCSI device even when Bacula has the
1038 regular tape device locked. (Needless to say, I don't recommend
1039 changing tape settings while a job is running.)
1040 - Lookup HP cleaning recommendations.
1041 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
1042 - Document doing table repair
1045 ===================================
1046 - Add macro expansions in JobDefs.
1047 Run Before Job = "SomeFile %{Level} %{Client}"
1048 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
1049 - Use non-blocking network I/O but if no data is available, use
1051 - Use gather write() for network I/O.
1052 - Autorestart on crash.
1053 - Add bandwidth limiting.
1054 - Add acks every once and a while from the SD to keep
1055 the line from timing out.
1056 - When an error in input occurs and conio beeps, you can back
1057 up through the prompt.
1058 - Detect fixed tape block mode during positioning by looking at
1059 block numbers in btape "test". Possibly adjust in Bacula.
1060 - Fix list volumes to output volume retention in some other
1061 units, perhaps via a directive.
1062 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
1063 with multiple priorities.
1064 - If you use restore replace=never, the directory attributes for
1065 non-existent directories will not be restored properly.
1067 - see lzma401.zip in others directory for new compression
1069 - Allow the user to select JobType for manual pruning/purging.
1070 - bscan does not put first of two volumes back with all info in
1072 - Implement the FreeBSD nodump flag in chflags.
1073 - Figure out how to make named console messages go only to that
1074 console and to the non-restricted console (new console class?).
1075 - Make restricted console prompt for password if *ask* is set or
1076 perhaps if password is undefined.
1077 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1080 ==== from Marc Schoechlin
1081 - the help-command should be more verbose
1082 (it should explain the paramters of the different
1084 -> its time-comsuming to consult the manual anytime
1085 you need a special parameter
1086 -> maybe its more easy to maintain this, if the
1087 descriptions of that commands are outsourced to
1089 - if the password is not configured in bconsole.conf
1090 you should be asked for it.
1091 -> sometimes you like to do restore on a customer-machine
1092 which shouldnt know the password for bacula.
1093 -> adding the password to the file favours admins
1094 to forget to remove the password after usage
1096 the protection of that file is less important
1097 - long-listed-output of commands should be scrollable
1098 like the unix more/less-command does
1099 -> if someone runs 200 and more machines, the lists could
1100 be a little long and complex
1101 - command-output should be shown column by column
1102 to reduce scrolling and to increase clarity
1104 - lsmark should list the selected files with full
1106 - wildcards for selecting and file and directories would be nice
1107 - any actions should be interuptable with STRG+C
1108 - command-expansion would be pretty cool
1110 - When the replace Never option is set, new directory permissions
1111 are not restored. See bug 213. To fix this requires creating a
1112 list of newly restored directories so that those directory
1113 permissions *can* be restored.
1114 - Add prune all command
1115 - Document fact that purge can destroy a part of a restore by purging
1116 one volume while others remain valid -- perhaps mark Jobs.
1117 - Add multiple-media-types.txt
1118 - look at mxt-changer.html
1119 - Make ? do a help command (no return needed).
1120 - Implement restore directory.
1121 - Document streams and how to implement them.
1122 - Try not to re-backup a file if a new hard link is added.
1123 - Add feature to backup hard links only, but not the data.
1124 - Fix stream handling to be simpler.
1125 - Add Priority and Bootstrap to Run a Job.
1126 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1128 - Remove View FileSet button from Run a Job dialog.
1129 - Handle prompt for restore job at end of Restore command.
1130 - Add display of total selected files to Restore window.
1131 - Add tree pane to left of window.
1132 - Add progress meter.
1133 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1134 - Add message to user to check for fixed block size when the forward
1135 space test fails in btape.
1136 - When unmarking a directory check if all files below are unmarked and
1137 then remove the + flag -- in the restore tree.
1138 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1139 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1140 - Revisit the question of multiple Volumes (disk) on a single device.
1141 - Add a block copy option to bcopy.
1142 - Finish work on Gnome restore GUI.
1143 - Fix "llist jobid=xx" where no fileset or client exists.
1144 - For each job type (Admin, Restore, ...) require only the really necessary
1145 fields.- Pass Director resource name as an option to the Console.
1146 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1147 - Add a .list all files in the restore tree (probably also a list all files)
1148 Do both a long and short form.
1149 - Allow browsing the catalog to see all versions of a file (with
1150 stat data on each file).
1151 - Restore attributes of directory if replace=never set but directory
1153 - Use SHA1 on authentication if possible.
1154 - See comtest-xxx.zip for Windows code to talk to USB.
1155 - Add John's appended files:
1156 Appended = { /files/server/logs/http/*log }
1157 and such files would be treated as follows.On a FULL backup, they would
1158 be backed up like any other file.On an INCREMENTAL backup, where a
1159 previous INCREMENTAL or FULL was already in thecatalogue and the length
1160 of the file wasgreater than the length of the last backup, only thedata
1161 added since the last backup will be dumped.On an INCREMENTAL backup, if
1162 the length of the file is less than thelength of the file with the same
1163 name last backed up, the completefile is dumped.On Windows systems, with
1164 creation date of files, we can be evensmarter about this and not count
1165 entirely upon the length.On a restore, the full and all incrementals
1166 since it will beapplied in sequence to restore the file.
1167 - Check new HAVE_WIN32 open bits.
1168 - Check if the tape has moved before writing.
1169 - Handling removable disks -- see below:
1170 - Keep track of tape use time, and report when cleaning is necessary.
1171 - Add FromClient and ToClient keywords on restore command (or
1172 BackupClient RestoreClient).
1173 - Implement a JobSet, which groups any number of jobs. If the
1174 JobSet is started, all the jobs are started together.
1175 Allow Pool, Level, and Schedule overrides.
1176 - Enhance cancel to timeout BSOCK packets after a specific delay.
1177 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1178 ua_status.!!! Thanks to Alan Brown for this tip.
1179 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1180 correctly for multiple simultaneous jobs.
1181 - Correct code so that FileSet MD5 is calculated for < and | filename
1183 - Implement the Media record flag that indicates that the Volume does disk
1185 - Implement VolAddr, which is used when Volume is addressed like a disk,
1186 and form it from VolFile and VolBlock.
1187 - Make multiple restore jobs for multiple media types specifying
1188 the proper storage type.
1189 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1190 pointer (rec) to try_repositioning().
1191 - Look at extracting Win data from BackupRead.
1192 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1193 which would take precidence over the Catalog "JobRetention".
1194 - Implement Label Format in Add and Label console commands.
1195 - Possibly up network buffers to 65K. Put on variable.
1196 - Put email tape request delays on one or more variables. User wants
1197 to cancel the job after a certain time interval. Maximum Mount Wait?
1198 - Job, Client, Device, Pool, or Volume?
1199 Is it possible to make this a directive which is *optional* in multiple
1200 resources, like Level? If so, I think I'd make it an optional directive
1201 in Job, Client, and Pool, with precedence such that Job overrides Client
1202 which in turn overrides Pool.
1204 - New Storage specifications:
1205 - Want to write to multiple storage devices simultaneously
1206 - Want to write to multiple storage devices sequentially (in one job)
1207 - Want to read/write simultaneously
1208 - Key is MediaType -- it must match
1210 Passed to SD as a sort of BSR record called Storage Specification
1214 MediaType -> Next MediaType
1216 Device -> Next Device
1218 Allow multiple Storage specifications
1226 Allow Multiple Pool specifications (note, Pool currently
1228 Allow Multiple MediaType specifications in Dir conf
1229 Allow Multiple Device specifications in Dir conf
1230 Perhaps keep this in a single SSR
1231 Tie a Volume to a specific device by using a MediaType that
1232 is contained in only one device.
1233 In SD allow Device to have Multiple MediaTypes
1235 - Ideas from Jerry Scharf:
1236 First let's point out some big pluses that bacula has for this
1238 more importantly it's active. Thank you so much for that
1239 even more important, it's not flaky
1240 it has an open access catalog, opening many possibilities
1241 it's pushing toward heterogeneous systems capability
1243 Macintosh file client
1244 macs are an interesting niche, but I fear a server is a rathole
1245 working bare iron recovery for windows
1246 the option for inc/diff backups not reset on fileset revision
1247 a) use both change and inode update time against base time
1248 b) do the full catalog check (expensive but accurate)
1249 sizing guide (how much system is needed to back up N systems/files)
1250 consultants on using bacula in building a disaster recovery system
1251 an integration guide
1252 or how to get at fancy things that one could do with bacula
1253 logwatch code for bacula logs (or similar)
1254 linux distro inclusion of bacula (brings good and bad, but necessary)
1255 win2k/XP server capability (icky but you asked)
1256 support for Oracle database ??
1258 - Look at adding SQL server and Exchange support for Windows.
1259 - Make dev->file and dev->block_num signed integers so that -1 can
1260 be an invalid value which happens with BSR.
1261 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1262 is needed to properly specify ranges.
1263 - Add progress of files/bytes to SD and FD.
1264 - Print warning message if FileId > 4 billion
1265 - do a "messages" before the first prompt in Console
1266 - Client does not show busy during Estimate command.
1267 - Implement Console mtx commands.
1268 - Implement a Mount Command and an Unmount Command where
1269 the users could specify a system command to be performed
1270 to do the mount, after which Bacula could attempt to
1271 read the device. This is for Removeable media such as a CDROM.
1272 - Most likely, this mount command would be invoked explicitly
1273 by the user using the current Console "mount" and "unmount"
1274 commands -- the Storage Daemon would do the right thing
1275 depending on the exact nature of the device.
1276 - As with tape drives, when Bacula wanted a new removable
1277 disk mounted, it would unmount the old one, and send a message
1278 to the user, who would then use "mount" as described above
1279 once he had actually inserted the disk.
1280 - Implement dump/print label to UA
1281 - Spool to disk only when the tape is full, then when a tape is hung move
1283 - bextract is sending everything to the log file ****FIXME****
1284 - Allow multiple Storage specifications (or multiple names on
1285 a single Storage specification) in the Job record. Thus a job
1286 can be backed up to a number of storage devices.
1287 - Implement some way for the File daemon to contact the Director
1288 to start a job or pass its DHCP obtained IP number.
1289 - Implement a query tape prompt/replace feature for a console
1290 - Copy console @ code to gnome2-console
1291 - Make sure that Bacula rechecks the tape after the 20 min wait.
1292 - Set IO_NOWAIT on Bacula TCP/IP packets.
1293 - Try doing a raw partition backup and restore by mounting a
1295 - From Lars Kellers:
1296 Yes, it would allow to highly automatic the request for new tapes. If a
1297 tape is empty, bacula reads the barcodes (native or simulated), and if
1298 an unused tape is found, it runs the label command with all the
1299 necessary parameters.
1301 By the way can bacula automatically "move" an empty/purged volume say
1302 in the "short" pool to the "long" pool if this pool runs out of volume
1304 - What to do about "list files job=xxx".
1305 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1306 file descriptor leak in Bacula.
1307 - Implement WrapCounters in Counters.
1308 - Add heartbeat from FD to SD if hb interval expires.
1309 - Can we dynamically change FileSets?
1310 - If pool specified to label command and Label Format is specified,
1311 automatically generate the Volume name.
1312 - Why can't SQL do the filename sort for restore?
1313 - Add ExhautiveRestoreSearch
1314 - Look at the possibility of loading only the necessary
1315 data into the restore tree (i.e. do it one directory at a
1316 time as the user walks through the tree).
1317 - Possibly use the hash code if the user selects all for a restore command.
1318 - Fix "restore all" to bypass building the tree.
1319 - Prohibit backing up archive device (findlib/find_one.c:128)
1320 - Implement Release Device in the Job resource to unmount a drive.
1321 - Implement Acquire Device in the Job resource to mount a drive,
1322 be sure this works with admin jobs so that the user can get
1323 prompted to insert the correct tape. Possibly some way to say to
1324 run the job but don't save the files.
1325 - Make things like list where a file is saved case independent for
1327 - Use autochanger to handle multiple devices.
1328 - Implement a Recycle command
1329 - Start working on Base jobs.
1330 - Implement UnsavedFiles DB record.
1331 - From Phil Stracchino:
1332 It would probably be a per-client option, and would be called
1333 something like, say, "Automatically purge obsoleted jobs". What it
1334 would do is, when you successfully complete a Differential backup of a
1335 client, it would automatically purge all Incremental backups for that
1336 client that are rendered redundant by that Differential. Likewise,
1337 when a Full backup on a client completed, it would automatically purge
1338 all Differential and Incremental jobs obsoleted by that Full backup.
1339 This would let people minimize the number of tapes they're keeping on
1340 hand without having to master the art of retention times.
1341 - When doing a Backup send all attributes back to the Director, who
1342 would then figure out what files have been deleted.
1343 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1344 explicit permission to do so. It should also mark the tape in error
1345 if there is an error.
1346 - Cancel waiting for Client connect in SD if FD goes away.
1348 - Implement timeout in response() when it should come quickly.
1349 - Implement a Slot priority (loaded/not loaded).
1350 - Implement "vacation" Incremental only saves.
1351 - Implement create "FileSet"?
1352 - Add prefixlinks to where or not where absolute links to FD.
1353 - Issue message to mount a new tape before the rewind.
1354 - Simplified client job initiation for portables.
1355 - If SD cannot open a drive, make it periodically retry.
1356 - Add more of the config info to the tape label.
1358 - Refine SD waiting output:
1359 Device is being positioned
1360 > Device is being positioned for append
1361 > Device is being positioned to file x
1363 - Figure out some way to estimate output size and to avoid splitting
1364 a backup across two Volumes -- this could be useful for writing CDROMs
1365 where you really prefer not to have it split -- not serious.
1366 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1367 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1368 actual data on the Volume and compare it.
1369 - Make bcopy read through bad tape records.
1370 - Program files (i.e. execute a program to read/write files).
1371 Pass read date of last backup, size of file last time.
1372 - Add Signature type to File DB record.
1373 - CD into subdirectory when open()ing files for backup to
1374 speed up things. Test with testfind().
1375 - Priority job to go to top of list.
1376 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1377 - Implement some way for the Console to dynamically create a job.
1378 - Solaris -I on tar for include list
1379 - Need a verbose mode in restore, perhaps to bsr.
1380 - bscan without -v is too quiet -- perhaps show jobs.
1381 - Add code to reject whole blocks if not wanted on restore.
1382 - Check if we can increase Bacula FD priorty in Win2000
1383 - Make sure the MaxVolFiles is fully implemented in SD
1384 - Check if both CatalogFiles and UseCatalog are set to SD.
1385 - Possibly add email to Watchdog if drive is unmounted too
1386 long and a job is waiting on the drive.
1387 - After unmount, if restore job started, ask to mount.
1388 - Add UA rc and history files.
1389 - put termcap (used by console) in ./configure and
1390 allow -with-termcap-dir.
1391 - Fix Autoprune for Volumes to respect need for full save.
1392 - Compare tape to Client files (attributes, or attributes and data)
1393 - Make all database Ids 64 bit.
1394 - Allow console commands to detach or run in background.
1395 - Add SD message variables to control operator wait time
1396 - Maximum Operator Wait
1397 - Minimum Message Interval
1398 - Maximum Message Interval
1399 - Send Operator message when cannot read tape label.
1400 - Verify level=Volume (scan only), level=Data (compare of data to file).
1401 Verify level=Catalog, level=InitCatalog
1403 - Add keyword search to show command in Console.
1404 - Events : tape has more than xxx bytes.
1405 - Complete code in Bacula Resources -- this will permit
1406 reading a new config file at any time.
1407 - Handle ctl-c in Console
1408 - Implement script driven addition of File daemon to config files.
1409 - Think about how to make Bacula work better with File (non-tape) archives.
1410 - Write Unix emulator for Windows.
1411 - Put memory utilization in Status output of each daemon
1412 if full status requested or if some level of debug on.
1413 - Make database type selectable by .conf files i.e. at runtime
1414 - Set flag for uname -a. Add to Volume label.
1415 - Restore files modified after date
1416 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1417 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1418 - Timout a job or terminate if link goes down, or reopen link and query.
1419 - Concept of precious tapes (cannot be reused).
1420 - Make bcopy copy with a single tape drive.
1421 - Permit changing ownership during restore.

1435 - Autolabel should be specified by DIR instead of SD.
1437 - Add media capacity
1438 - AutoScan (check checksum of tape)
1439 - Format command = "format /dev/nst0"
1443 - Seek resolution (usually corresponds to buffer size)
1444 - EODErrorCode=ENOSPC or code
1445 - Partial Read error code
1446 - Partial write error code
1447 - Nonformatted read error
1448 - Nonformatted write error
1449 - WriteProtected error
1453 - IgnoreCloseErrors=yes
1463 - FD sends unsaved file list to Director at end of job (see
1465 - File daemon should build list of files skipped, and then
1466 at end of save retry and report any errors.
1467 - Write a Storage daemon that uses pipes and
1468 standard Unix programs to write to the tape.
1470 - Need something that monitors the JCR queue and
1471 times out jobs by asking the deamons where they are.
1472 - Enhance Jmsg code to permit buffering and saving to disk.
1473 - device driver = "xxxx" for drives.
1474 - Verify from Volume
1475 - Ensure that /dev/null works
1476 - Need report class for messages. Perhaps
1477 report resource where report=group of messages
1478 - enhance scan_attrib and rename scan_jobtype, and
1479 fill in code for "since" option
1480 - Director needs a time after which the report status is sent
1481 anyway -- or better yet, a retry time for the job.
1482 - Don't reschedule a job if previous incarnation is still running.
1483 - Some way to automatically backup everything is needed????
1484 - Need a structure for pending actions:
1486 - termination status (part of buffered msgs?)
1488 Read, Write, Clean, Delete
1489 - Login to Bacula; Bacula users with different permissions:
1490 owner, group, user, quotas
1491 - Store info on each file system type (probably in the job header on tape.
1492 This could be the output of df; or perhaps some sort of /etc/mtab record.
1494 ========= ideas ===============
1495 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1496 To: <kern@sibbald.com>
1497 Subject: RE: [Bacula-users] future large programming jobs
1498 Date: Thu, 26 Feb 2004 11:34:54 -0600
1500 I noticed the subject thread and thought I would offer the following
1501 merely as sources of ideas, i.e. something to think about, not even as
1502 strong as a request. In my former life (before retiring) I often
1503 dealt with backups and storage management issues/products as a
1504 developer and as a consultant. I am currently migrating my personal
1505 network from amanda to bacula specifically because of the ability to
1506 cross media boundaries during storing backups.
1507 Are you familiar with the commercial product called ADSM (I think IBM
1508 now sells it under the Tivoli label)? It has a couple of interesting
1509 ideas that may apply to the following topics.
1511 1. Migration: Consider that when you need to restore a system, there
1512 may be pressure to hurry. If all the information for a single client
1513 can eventually end up on the same media (and in chronological order),
1514 the restore is facillitated by not having to search past information
1515 from other clients. ADSM has the concept of "client affinity" that
1516 may be associated with it's storage pools. It seems to me that this
1517 concept (as an optional feature) might fit in your architecture for
1520 ADSM also has the concept of defining one or more storage pools as
1521 "copy pools" (almost mirrors, but only in the sense of contents).
1522 These pools provide the ability to have duplicte data stored both
1523 onsite and offsite. The copy process can be scheduled to be handled
1524 by their storage manager during periods when there is no backup
1525 activity. Again, the migration process might be a place to consider
1526 implementing something like this.
1529 > It strikes me that it would be very nice to be able to do things
1531 > have the Job(s) backing up the machines run, and once they have all

1537 > mechanism described below would probably make it very easy.
1539 This is the goal. In the first step (before events), you simply
1541 the Migration to tape later.
1543 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1544 the database. Once a file (unique by path and metadata such as dates,
1545 size, ownership, etc.) is in a copy pool, no more copies are made. In
1546 other words, when you start ADSM, it begins like your concept of a
1547 base job. After that it is in the "incremental" mode. You can
1548 configure the number of "generations" of files to be retained, plus a
1549 retention date after which even old generations are purged. The
1550 database tracks the contents of media and projects the percentage of
1551 each volume that is valid. When the valid content of a volume drops
1552 below a configured percentage, the valid data are migrated to another
1553 volume and the old volume is marked as empty. Note, this requires
1554 ADSM to have an idea of the contents of a client, i.e. marking the
1555 database when an existing file was deleted, but this would solve your
1556 issue of restoring a client without restoring deleted files.
1558 This is pretty far from what bacula now does, but if you are going to
1559 rip things up for Base jobs,.....
1560 Also, the benefits of this are huge for very large shops, especially
1561 with media robots, but are a pain for shops with manual media
1565 > Base jobs sound pretty useful, but I'm not dying for them.
1567 Nobody is dying for them, but when you see what it does, you will die
1570 3. Restoring deleted files: Since I think my comments in (2) above
1571 have low probability of implementation, I'll also suggest that you
1572 could approach the issue of deleted files by a mechanism of having the
1573 fd report to the dir, a list of all files on the client for every
1574 backup job. The dir could note in the database entry for each file
1575 the date that the file was seen. Then if a restore as of date X takes
1576 place, only files that exist from before X until after X would be
1577 restored. Probably the major cost here is the extra date container in
1578 each row of the files table.
1580 Thanks for "listening". I hope some of this helps. If you want to
1581 contact me, please send me an email - I read some but not all of the
1582 mailing list traffic and might miss a reply there.
1584 Please accept my compliments for bacula. It is doing a great job for
1585 me!! I sympathize with you in the need to wrestle with excelence in
1586 execution vs. excelence in feature inclusion.
1591 ==============================
1594 - Design at hierarchial storage for Bacula. Migration and Clone.
1595 - Implement FSM (File System Modules).
1596 - Audit M_ error codes to ensure they are correct and consistent.
1597 - Add variable break characters to lex analyzer.
1598 Either a bit mask or a string of chars so that
1599 the caller can change the break characters.
1600 - Make a single T_BREAK to replace T_COMMA, etc.
1601 - Ensure that File daemon and Storage daemon can
1602 continue a save if the Director goes down (this
1603 is NOT currently the case). Must detect socket error,
1604 buffer messages for later.
1605 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1606 - Add ability to backup to two Storage devices (two SD sessions) at
1607 the same time -- e.g. onsite, offsite.
1608 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1609 someway to do so with every volume that has less than x% valid
1613 Migration: Move a backup from one Volume to another
1614 Clone: Copy a backup -- two Volumes
1617 ======================================================
1619 It is somewhat like a Full save becomes an incremental since
1620 the Base job (or jobs) plus other non-base files.
1622 - A Base backup is same as Full backup, just different type.
1623 - New BaseFiles table that contains:
1625 BaseJobId - Base JobId referenced for this FileId (needed ???)
1626 JobId - JobId currently running
1627 FileId - File not backed up, exists in Base Job
1628 FileIndex - FileIndex from Base Job.
1629 i.e. for each base file that exists but is not saved because
1630 it has not changed, the File daemon sends the JobId, BaseId,
1631 FileId, FileIndex back to the Director who creates the DB entry.
1632 - To initiate a Base save, the Director sends the FD
1633 the FileId, and full filename for each file in the Base.
1634 - When the FD finds a Base file, he requests the Director to
1635 send him the full File entry (stat packet plus MD5), or
1636 conversely, the FD sends it to the Director and the Director
1637 says yes or no. This can be quite rapid if the FileId is kept
1638 by the FD for each Base Filename.
1639 - It is probably better to have the comparison done by the FD
1640 despite the fact that the File entry must be sent across the
1642 - An alternative would be to send the FD the whole File entry
1643 from the start. The disadvantage is that it requires a lot of
1644 space. The advantage is that it requires less communications
1646 - The Job record must be updated to indicate that one or more
1648 - At end of Job, FD returns:
1649 1. Count of base files/bytes not written to tape (i.e. matches)
1650 2. Count of base file that were saved i.e. had changed.
1651 - No tape record would be written for a Base file that matches, in the
1652 same way that no tape record is written for Incremental jobs where
1653 the file is not saved because it is unchanged.
1654 - On a restore, all the Base file records must explicitly be
1655 found from the BaseFile tape. I.e. for each Full save that is marked
1656 to have one or more Base Jobs, search the BaseFile for all occurrences
1658 - An optimization might be to make the BaseFile have:
1664 This would avoid the need to explicitly fetch each File record for
1665 the Base job. The Base Job record will be fetched to get the
1666 VolSessionId and VolSessionTime.

1707 Unloading Data Transfer Element into Storage Element 15...done
1709 (just to verify it remembers where it came from, however it can be
1710 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1712 There needs to be a table of drive # to devices somewhere - If there are
1713 multiple changers or drives there may not be a 1:1 correspondance between
1714 changer drive number and system device name - and depending on the way the
1715 drives are hooked up to scsi busses, they may not be linearly numbered
1716 from an offset point either.something like
1718 Autochanger drives = 2
1719 Autochanger drive 0 = /dev/nst1
1720 Autochanger drive 1 = /dev/nst2
1721 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1722 times, not just for multidrive changers. For a 1 drive changer, that's
1728 MTX's manpage (1.2.15):
1729 unload [<slotnum>] [ <drivenum> ]
1730 Unloads media from drive <drivenum> into slot
1731 <slotnum>. If <drivenum> is omitted, defaults to
1732 drive 0 (as do all commands). If <slotnum> is
1733 omitted, defaults to the slot that the drive was
1734 loaded from. Note that there's currently no way
1735 to say 'unload drive 1's media to the slot it
1736 came from', other than to explicitly use that
1737 slot number as the destination.AB

1775 Handling removable disks
1777 From: Karl Cunningham <karlc@keckec.com>
1779 My backups are only to hard disk these days, in removable bays. This is my
1780 idea of how a backup to hard disk would work more smoothly. Some of these
1781 things Bacula does already, but I mention them for completeness. If others
1782 have better ways to do this, I'd like to hear about it.
1784 1. Accommodate several disks, rotated similar to how tapes are. Identified
1785 by partition volume ID or perhaps by the name of a subdirectory.
1786 2. Abort & notify the admin if the wrong disk is in the bay.
1787 3. Write backups to different subdirectories for each machine to be backed
1789 4. Volumes (files) get created as needed in the proper subdirectory, one
1791 5. When a disk is recycled, remove or zero all old backup files. This is
1792 important as the disk being recycled may be close to full. This may be
1793 better done manually since the backup files for many machines may be
1794 scattered in many subdirectories.
1799 - Why the heck doesn't bacula drop root priviledges before connecting to
1801 - Look at using posix_fadvise(2) for backups -- see bug #751.
1802 Possibly add the code at findlib/bfile.c:795
1803 /* TCP socket options */
1804 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1805 - Fix bnet_connect() code to set a timer and to use time to
1807 - Implement 4th argument to make_catalog_backup that passes hostname.
1808 - Test FIFO backup/restore -- make regression
1809 - Please mount volume "xxx" on Storage device ... should also list
1810 Pool and MediaType in case user needs to create a new volume.
1811 - On restore add Restore Client, Original Client.

1820 - Check if gnome-console works with TLS.
1821 - the director seg faulted when I omitted the pool directive from a
1822 job resource. I was experimenting and thought it redundant that I had
1823 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1824 apparently not. This happened when I removed the pool directive and
1825 started the director.
1826 - Add Where: client:/.... to restore job report.
1827 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1828 does the right thing.
1829 - FD-SD quick disconnect
1830 - Building the in memory restore tree is slow.
1831 - Erabt if min_block_size > max_block_size
1832 - Add the ability to consolidate old backup sets (basically do a restore
1833 to tape and appropriately update the catalog). Compress Volume sets.
1834 Might need to spool via file is only one drive is available.
1835 - Why doesn't @"xxx abc" work in a conf file?
1836 - Don't restore Solaris Door files:
1837 #define S_IFDOOR in st_mode.
1838 see: http://docs.sun.com/app/docs/doc/816-5173/6mbb8ae23?a=view#indexterm-360
1839 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
1840 - Implement Despooling data status.
1841 - Use E'xxx' to escape PostgreSQL strings.
1842 - Look at mincore: http://insights.oetiker.ch/linux/fadvise.html
1843 - Unicode input http://en.wikipedia.org/wiki/Byte_Order_Mark
1844 - Look at moving the Storage directive from the Job to the
1845 Pool in the default conf files.
1846 - Look at in src/filed/backup.c
1847 > pm_strcpy(ff_pkt->fname, ff_pkt->fname_save);
1848 > pm_strcpy(ff_pkt->link, ff_pkt->link_save);
1849 - Add Catalog = to Pool resource so that pools will exist
1850 in only one catalog -- currently Pools are "global".
1851 - Add TLS to bat (should be done).
1852 === Duplicate jobs ===
1853 - Done, but implemented somewhat differently than described below!!!
1855 hese apply only to backup jobs.
1857 1. Allow Duplicate Jobs = Yes | No | Higher (Yes)
1859 2. Duplicate Job Interval = <time-interval> (0)
1861 The defaults are in parenthesis and would produce the same behavior as today.
1863 If Allow Duplicate Jobs is set to No, then any job starting while a job of the
1864 same name is running will be canceled.
1866 If Allow Duplicate Jobs is set to Higher, then any job starting with the same
1867 or lower level will be canceled, but any job with a Higher level will start.
1868 The Levels are from High to Low: Full, Differential, Incremental
1870 Finally, if you have Duplicate Job Interval set to a non-zero value, any job
1871 of the same name which starts <time-interval> after a previous job of the
1872 same name would run, any one that starts within <time-interval> would be
1873 subject to the above rules. Another way of looking at it is that the Allow
1874 Duplicate Jobs directive will only apply after <time-interval> of when the
1875 previous job finished (i.e. it is the minimum interval between jobs).
1879 Allow Duplicate Jobs = Yes | No | HigherLevel | CancelLowerLevel (Yes)
1881 Where HigherLevel cancels any waiting job but not any running job.
1882 Where CancelLowerLevel is same as HigherLevel but cancels any running job or
1885 Duplicate Job Proximity = <time-interval> (0)
1887 My suggestion was to define it as the minimum guard time between
1888 executions of a specific job -- ie, if a job was scheduled within Job
1889 Proximity number of seconds, it would be considered a duplicate and
1892 Skip = Do not allow two or more jobs with the same name to run
1893 simultaneously within the proximity interval. The second and subsequent
1894 jobs are skipped without further processing (other than to note the job
1895 and exit immediately), and are not considered errors.
1897 Fail = The second and subsequent jobs that attempt to run during the
1898 proximity interval are cancelled and treated as error-terminated jobs.
1900 Promote = If a job is running, and a second/subsequent job of higher
1901 level attempts to start, the running job is promoted to the higher level
1902 of processing using the resources already allocated, and the subsequent
1903 job is treated as in Skip above.
1909 Allow = yes|no (no = default)
1911 AllowHigherLevel = yes|no (no)
1913 AllowLowerLevel = yes|no (no)
1915 AllowSameLevel = yes|no
1917 Cancel = Running | New (no)
1919 CancelledStatus = Fail | Skip (fail)
1921 Job Proximity = <time-interval> (0)
1922 My suggestion was to define it as the minimum guard time between
1923 executions of a specific job -- ie, if a job was scheduled within Job
1924 Proximity number of seconds, it would be considered a duplicate and
1930 - Fix bpipe.c so that it does not modify results pointer.
1931 ***FIXME*** calling sequence should be changed.
