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
89 - Backup conf/exe (all daemons)
90 - Backup up system state
91 - Detect state change of system (verify)
92 - Synthetic Full, Diff, Inc (Virtual, Reconstructed)

109 Complete rework of the scheduling system (not in list)
110 Performance and usage instrumentation (not in list)
111 See email of 21Aug2007 for details.
112 - Look at: http://tech.groups.yahoo.com/group/cfg2html
113 and http://www.openeyet.nl/scc/ for managing customer changes
117 - Can be posible modify package to create and use configuration files in
122 /etc/bacula/bacula-dir.conf
123 /etc/bacula/conf.d/pools.conf
124 /etc/bacula/conf.d/clients.conf
125 /etc/bacula/conf.d/storages.conf
127 and into bacula-dir.conf file include
129 @/etc/bacula/conf.d/pools.conf
130 @/etc/bacula/conf.d/clients.conf
131 @/etc/bacula/conf.d/storages.conf
132 - Possibly add an Inconsistent state when a Volume is in error
134 - Fix #ifdefing so that smartalloc can be disabled. Check manual
135 -- the default is enabled.
136 - Change calling sequence to delete_job_id_range() in ua_cmds.c
137 the preceding strtok() is done inside the subroutine only once.
138 - Dangling softlinks are not restored properly. For example, take a
139 soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
140 move the directory to another machine where the file /usr/share/autoconf does
141 not exist, back it up, then try a full restore. It fails.
142 - Check for FD compatibility -- eg .nobackup ...
143 - Re-check new dcr->reserved_volume
144 - Softlinks that point to non-existent file are not restored in restore all,
145 but are restored if the file is individually selected. BUG!
146 - Doc Duplicate Jobs.
147 - New directive "Delete purged Volumes"
149 - Prune by Job Level (Full, Differential, Incremental)
150 - Strict automatic pruning
151 - Implement unmount of USB volumes.
152 - Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
153 Win32 to avoid patent problems.
154 - Implement multiple jobid specification for the cancel command,
155 similar to what is permitted on the update slots command.
156 - Implement Bacula plugins -- design API
157 - modify pruning to keep a fixed number of versions of a file,
159 - the cd-command should allow complete paths
160 i.e. cd /foo/bar/foo/bar
161 -> if a customer mails me the path to a certain file,
162 its faster to enter the specified directory
163 - Make tree walk routines like cd, ls, ... more user friendly
164 by handling spaces better.
168 MA = (last_MA * 3 + rate) / 4
169 rate = (bytes - last_bytes) / (runtime - last_runtime)
170 - Add a recursive mark command (rmark) to restore.
171 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
172 of the same level and does not permit multiple simultaneous
173 running of that Job (i.e. lets any previous invocation finish
174 before doing Interval testing).
175 - Look at simplifying File exclusions.
177 - Auto update of slot:
178 rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
179 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03

181 02-Nov 12:58 rufus-sd JobId 10: Invalid slot=0 defined in catalog for Volume "Vol001" on "DDS-4" (/dev/nst0). Manual load my be required.
182 02-Nov 12:58 rufus-sd JobId 10: 3301 Issuing autochanger "loaded? drive 0" command.
183 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
184 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
185 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.

187 - Eliminate: /var is a different filesystem. Will not descend from / into /var
188 - Separate Files and Directories in catalog
189 - Create FileVersions table
190 - Look at rsysnc for incremental updates and dedupping
191 - Add MD5 or SHA1 check in SD for data validation
192 - finish implementation of fdcalled -- see ua_run.c:105
193 - Fix problem in postgresql.c in my_postgresql_query, where the
194 generation of the error message doesn't differentiate result==NULL
195 and a bad status from that result. Not only that, the result is
196 cleared on a bail_out without having generated the error message.
198 - Implement SDErrors (must return from SD)
199 - Implement USB keyboard support in rescue CD.
200 - Implement continue spooling while despooling.
201 - Remove all install temp files in Win32 PLUGINSDIR.
202 - Audit retention periods to make sure everything is 64 bit.
203 - No where in restore causes kaboom.
204 - Performance: multiple spool files for a single job.
205 - Performance: despool attributes when despooling data (problem
206 multiplexing Dir connection).
207 - Make restore use the in-use volume reservation algorithm.
208 - When Pool specifies Storage command override does not work.
209 - Implement wait_for_sysop() message display in wait_for_device(), which
210 now prints warnings too often.
211 - Ensure that each device in an Autochanger has a different
213 - Look at sg_logs -a /dev/sg0 for getting soft errors.
214 - btape "test" command with Offline on Unmount = yes
216 This test is essential to Bacula.
218 I'm going to write one record in file 0,
219 two records in file 1,
220 and three records in file 2
222 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715
223 dev.c:714 Bad call to rewind. Device "LTO" (/dev/nst0) not open
224 02-Feb 11:00 btape: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation
225 Kaboom! btape, btape got signal 11. Attempting traceback.
227 - Encryption -- email from Landon
228 > The backup encryption algorithm is currently not configurable, and is
229 > set to AES_128_CBC in src/filed/backup.c. The encryption code
230 > supports a number of different ciphers (as well as adding arbitrary
231 > new ones) -- only a small bit of code would be required to map a
232 > configuration string value to a CRYPTO_CIPHER_* value, if anyone is
233 > interested in implementing this functionality.
235 - Figure out some way to "automatically" backup conf changes.
236 - Add the OS version back to the Win32 client info.
237 - Restarted jobs have a NULL in the from field.
238 - Modify SD status command to indicate when the SD is writing
239 to a DVD (the device is not open -- see bug #732).
240 - Look at the possibility of adding "SET NAMES UTF8" for MySQL,
241 and possibly changing the blobs into varchar.
242 - Ensure that the SD re-reads the Media record if the JobFiles
243 does not match -- it may have been updated by another job.
245 - Test Volume compatibility between machine architectures
246 - Encryption documentation
247 - Wrong jobbytes with query 12 (todo)
248 - Bare-metal recovery Windows (todo)
253 - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
255 - Maximum number of scratch volumes
257 - Next Pool (already have)
258 - Reclamation threshold
260 - Reuse delay (after all files purged from volume before it can be used)
261 - Copy Pool = xx, yyy (or multiple lines).
263 - Allow pool selection during restore.
265 - Average tape size from Eric
266 SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
267 count(Media.MediaId) AS volnum,
268 sum(Media.VolBytes) AS voltotal,
269 Media.PoolId AS PoolId,
270 Media.MediaType AS MediaType
272 LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,
273 Media.MediaType AS MediaType
275 WHERE Media.VolStatus = 'Full'
276 GROUP BY Media.MediaType
277 ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
278 GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
282 - Add doc for bweb -- especially Installation
284 http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
286 - Despool attributes in separate thread
289 - Check why restore repeatedly sends Rechdrs between
290 each data chunk -- according to James Harper 9Jan07.
293 - Full at least once a month, ...
294 - Cancel Inc if Diff/Full running
295 - More intelligent re-run
296 - New/deleted file backup
298 - Incremental backup -- rsync, Stow
302 - Try to fix bscan not working with multiple DVD volumes bug #912.
303 - Look at mondo/mindi
304 - Make Bacula by default not backup tmpfs, procfs, sysfs, ...
305 - Fix hardlinked immutable files when linking a second file, the
306 immutable flag must be removed prior to trying to link it.
307 - Implement Python event for backing up/restoring a file.
308 - Change dbcheck to tell users to use native tools for fixing
309 broken databases, and to ensure they have the proper indexes.
310 - add udev rules for Bacula devices.
311 - If a job terminates, the DIR connection can close before the
312 Volume info is updated, leaving the File count wrong.
313 - Look at why SIGPIPE during connection can cause seg fault in
314 writing the daemon message, when Dir dropped to bacula:bacula
315 - Look at zlib 32 => 64 problems.
316 - Possibly turn on St. Bernard code.
317 - Fix bextract to restore ACLs, or better yet, use common routines.
318 - Do we migrate appendable Volumes?
319 - Remove queue.c code.
320 - Print warning message if LANG environment variable does not specify
322 - New dot commands from Arno.
323 .show device=xxx lists information from one storage device, including
324 devices (I'm not even sure that information exists in the DIR...)
325 .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
326 better machine-readable output like "Ok" or "Error busy"
327 .move eject device=xxx toslot=yyy the same as above, but with a new
328 target slot. The catalog should be updated accordingly.
329 .move transfer device=xxx fromslot=yyy toslot=zzz

359 - Possibly allow SD to spool even if a tape is not mounted.
360 - Fix re-read of last block to check if job has actually written
361 a block, and check if block was written by a different job
362 (i.e. multiple simultaneous jobs writing).
363 - Figure out how to configure query.sql. Suggestion to use m4:
364 == changequote.m4 ===
365 changequote(`[',`]')dnl
366 ==== query.sql.in ===
367 :List next 20 volumes to expire
369 Pool.Name AS PoolName,
374 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
376 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
380 ON Media.PoolId=Pool.PoolId
381 WHERE Media.LastWritten>0
385 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
387 The problem is that it requires m4, which is not present on all machines
389 - Given all the problems with FIFOs, I think the solution is to do something a
390 little different, though I will look at the code and see if there is not some
391 simple solution (i.e. some bug that was introduced). What might be a better
392 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
393 write data to a program rather than the FIFO. For example, suppose you
398 Then, I could imagine if you backup and restore this file with a direct
399 reference as is currently done for fifos, instead, during backup Bacula will
402 /home/kern/my-fifo.backup
404 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
407 /home/kern/my-fifo.restore
409 and send the data backed up to stdout. These programs can either be an
410 executable or a shell script and they need only read/write to stdin/stdout.
412 I think this would give a lot of flexibility to the user without making any
413 significant changes to Bacula.
418 select FilenameId from Filename where Name='';
419 # Get list of all directories referenced in a Backup.
420 select Path.Path from Path,File where File.JobId=nnn and

422 order by Path.Path ASC;
424 - Look into using Dart for testing

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

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

594 1. When jobs are running and bacula for some reason crashes or if I do a
595 restart it remembers and jobs it was running before it crashed or restarted
596 as of now I loose all jobs if I restart it.
598 2. When spooling and in the midway if client is disconnected for instance a
599 laptop bacula completely discard the spool. It will be nice if it can write
600 that spool to tape so there will be some backups for that client if not all.
602 3. We have around 150 clients machines it will be nice to have a option to
603 upgrade all the client machines bacula version automatically.
605 4. Atleast one connection should be reserved for the bconsole so at heavy load
606 I should connect to the director via bconsole which at sometimes I can't
608 5. Another most important feature that is missing, say at 10am I manually
609 started backup of client abc and it was a full backup since client abc has
610 no backup history and at 10.30am bacula again automatically started backup of
611 client abc as that was in the schedule. So now we have 2 multiple Full
612 backups of the same client and if we again try to start a full backup of
613 client backup abc bacula won't complain. That should be fixed.
615 - For Windows disaster recovery see http://unattended.sf.net/
616 - regardless of the retention period, Bacula will not prune the
617 last Full, Diff, or Inc File data until a month after the
618 retention period for the last Full backup that was done.
619 - update volume=xxx --- add status=Full
620 - Remove old spool files on startup.
621 - Exclude SD spool/working directory.
622 - Refuse to prune last valid Full backup. Same goes for Catalog.
624 - Make a callback when Rerun failed levels is called.
625 - Give Python program access to Scheduled jobs.
626 - Add setting Volume State via Python.
627 - Python script to save with Python, not save, save with Bacula.
628 - Python script to do backup.
630 - Change the Priority, Client, Storage, JobStatus (error)
631 at the start of a job.
632 - Why is SpoolDirectory = /home/bacula/spool; not reported
633 as an error when writing a DVD?
634 - Make bootstrap file handle multiple MediaTypes (SD)
635 - Remove all old Device resource code in Dir and code to pass it
636 back in SD -- better, rework it to pass back device statistics.
637 - Check locking of resources -- be sure to lock devices where previously
638 resources were locked.
639 - The last part is left in the spool dir.
642 - In restore don't compare byte count on a raw device -- directory
643 entry does not contain bytes.
646 - Max Vols limit in Pool off by one?
647 - Implement Files/Bytes,... stats for restore job.
648 - Implement Total Bytes Written, ... for restore job.
649 - Despool attributes simultaneously with data in a separate
650 thread, rejoined at end of data spooling.
651 - 7. Implement new Console commands to allow offlining/reserving drives,
652 and possibly manipulating the autochanger (much asked for).
653 - Add start/end date editing in messages (%t %T, %e?) ...
654 - Add ClientDefs similar to JobDefs.
655 - Print more info when bextract -p accepts a bad block.
656 - Fix FD JobType to be set before RunBeforeJob in FD.
657 - Look at adding full Volume and Pool information to a Volume
658 label so that bscan can get *all* the info.
659 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
660 and there is only one volume in the pool, refuse to do it -- otherwise
661 he fills the Volume, then immediately starts reusing it.
662 - Implement copies and stripes.
663 - Add history file to console.
664 - Each file on tape creates a JobMedia record. Peter has 4 million
665 files spread over 10000 tape files and four tapes. A restore takes
666 16 hours to build the restore list.
667 - Add and option to check if the file size changed during backup.
668 - Make sure SD deletes spool files on error exit.
669 - Delete old spool files when SD starts.
670 - When labeling tapes, if you enter 000026, Bacula uses
671 the tape index rather than the Volume name 000026.
672 - Add offline tape command to Bacula console.
674 Enter MediaId or Volume name: 32
675 Enter new Volume name: DLT-20Dec04
676 Automatically selected Pool: Default
677 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

684 Label command failed for Volume DLT-20Dec04.
685 Do not forget to mount the drive!!!
686 - Bug: if a job is manually scheduled to run later, it does not appear
687 in any status report and cannot be cancelled.
689 ==== Keeping track of deleted/new files ====
690 - To mark files as deleted, run essentially a Verify to disk, and
691 when a file is found missing (MarkId != JobId), then create
692 a new File record with FileIndex == -1. This could be done
693 by the FD at the same time as the backup.
695 My "trick" for keeping track of deletions is the following.
696 Assuming the user turns on this option, after all the files
697 have been backed up, but before the job has terminated, the
698 FD will make a pass through all the files and send their
699 names to the DIR (*exactly* the same as what a Verify job
700 currently does). This will probably be done at the same
701 time the files are being sent to the SD avoiding a second
702 pass. The DIR will then compare that to what is stored in
703 the catalog. Any files in the catalog but not in what the
704 FD sent will receive a catalog File entry that indicates
705 that at that point in time the file was deleted. This
706 either transmitted to the FD or simultaneously computed in
707 the FD, so that the FD can put a record on the tape that
708 indicates that the file has been deleted at this point.
709 A delete file entry could potentially be one with a FileIndex
710 of 0 or perhaps -1 (need to check if FileIndex is used for
711 some other thing as many of the Bacula fields are "overloaded"
714 During a restore, any file initially picked up by some
715 backup (Full, ...) then subsequently having a File entry
716 marked "delete" will be removed from the tree, so will not
717 be restored. If a file with the same name is later OK it
718 will be inserted in the tree -- this already happens. All
719 will be consistent except for possible changes during the
722 Since I'm on the subject, some of you may be wondering what
723 the utility of the in memory tree is if you are going to
724 restore everything (at least it comes up from time to time
725 on the list). Well, it is still *very* useful because it
726 allows only the last item found for a particular filename
727 (full path) to be entered into the tree, and thus if a file
728 is backed up 10 times, only the last copy will be restored.
729 I recently (last Friday) restored a complete directory, and
730 the Full and all the Differential and Incremental backups
731 spanned 3 Volumes. The first Volume was not even mounted
732 because all the files had been updated and hence backed up
733 since the Full backup was made. In this case, the tree
734 saved me a *lot* of time.
736 Make sure this information is stored on the tape too so
737 that it can be restored directly from the tape.
739 All the code (with the exception of formally generating and
740 saving the delete file entries) already exists in the Verify
741 Catalog command. It explicitly recognizes added/deleted files since
742 the last InitCatalog. It is more or less a "simple" matter of
743 taking that code and adapting it slightly to work for backups.
745 Comments from Martin Simmons (I think they are all covered):
746 Ok, that should cover the basics. There are few issues though:
748 - Restore will depend on the catalog. I think it is better to include the
749 extra data in the backup as well, so it can be seen by bscan and bextract.
751 - I'm not sure if it will preserve multiple hard links to the same inode. Or
752 maybe adding or removing links will cause the data to be dumped again?
754 - I'm not sure if it will handle renamed directories. Possibly it will work
755 by dumping the whole tree under a renamed directory?
757 - It remains to be seen how the backup performance of the DIR's will be
758 affected when comparing the catalog for a large filesystem.
760 1. Use the current Director in-memory tree code (very fast), but currently in
761 memory. It probably could be paged.
763 2. Use some DB such as Berkeley DB or SQLite. SQLite is already compiled and
764 built for Win32, and it is something we could compile into the program.
766 3. Implement our own custom DB code.
768 Note, by appropriate use of Directives in the Director, we can dynamically
769 decide if the work is done in the Director or in the FD, and we can even
770 allow the user to choose.
772 === most recent accurate file backup/restore ===
773 Here is a sketch (i.e. more details must be filled in later) that I recently
774 made of an algorithm for doing Accurate Backup.
776 1. Dir informs FD that it is doing an Accurate backup and lookup done by
779 2. FD passes through the file system doing a normal backup based on normal
780 conditions, recording the names of all files and their attributes, and
781 indicating which files were backed up. This is very similar to what Verify
784 3. The Director receives the two lists of files at the end of the FD backup.
785 One, files backed up, and one files not backed up. It then looks up all the
786 files not backed up (using Verify style code).
788 4. The Dir sends the FD a list of:
789 a. Additional files to backup (based on user specified criteria, name, size
790 inode date, hash, ...).
793 5. Dir deletes list of file not backed up.
795 6. FD backs up additional files generates a list of those backed up and sends
796 it to the Director, which adds it to the list of files backed up. The list
797 is now complete and current.
799 7. The FD generates delete records for all the files that were deleted and
802 8. The Dir deletes the previous CurrentBackup list, and then does a
803 transaction insert of the new list that it has.
805 9. The rest works as before ...
809 Two new tables needed.
810 1. CurrentBackupId table that contains Client, JobName, FileSet, and a unique
811 BackupId. This is created during a Full save, and the BackupId can be set to
812 the JobId of the Full save. It will remain the same until another Full
813 backup is done. That is when new records are added during a Differential or
814 Incremental, they must use the same BackupId.
816 2. CurrentBackup table that contains essentially a File record (less a number
817 of fields, but with a few extra fields) -- e.g. a flag that the File was
818 backed up by a Full save (this permits doing a Differential). The unique
819 BackupId allows us to look up the CurrentBackup for a particular Client,
820 Jobname, FileSet using that unique BackupId as the key, so this table must be
821 indexed by the BackupId.
823 Note any time a file is saved by the FD other than during a Full save, the
824 Full save flag is cleared. When doing a Differential backup, if a file has
825 the Full save flag set, it is skipped, otherwise it is backed up. For an
826 Incremental backup, we check to see if the file has changed since the last
827 time we backed it up.
829 Deleted files should have FileIndex == 0
833 How about introducing a Type = MgmtPolicy job type? That job type would
834 be responsible for scanning the Bacula environment looking for specific
835 conditions, and submitting the appropriate jobs for implementing said
839 Name = "Migration-Policy"
841 Policy Selection Job Type = Migrate
842 Scope = "<keyword> <operator> <regexp>"
843 Threshold = "<keyword> <operator> <regexp>"
844 Job Template = <template-name>
847 Where <keyword> is any legal job keyword, <operator> is a comparison
848 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
849 appropriate regexp. I could see an argument for Scope and Threshold
850 being SQL queries if we want to support full flexibility. The
851 Migration-Policy job would then get scheduled as frequently as a site
852 felt necessary (suggested default: every 15 minutes).
857 Name = "Migration-Policy"
859 Policy Selection Job Type = Migration
861 Threshold = "Migration Selection Type = LowestUtil"
862 Job Template = "MigrationTemplate"
865 would select all pools for examination and generate a job based on
866 MigrationTemplate to automatically select the volume with the lowest
867 usage and migrate it's contents to the nextpool defined for that pool.
869 This policy abstraction would be really handy for adjusting the behavior
870 of Bacula according to site-selectable criteria (one thing that pops
871 into mind is Amanda's ability to automatically adjust backup levels
872 depending on various criteria).
878 - Add Pool/Storage override regression test.
879 - Add delete JobId to regression.
880 - Add a regression test for dbcheck.
881 - New test to add bscan to four-concurrent-jobs regression,
882 i.e. after the four-concurrent jobs zap the
883 database as is done in the bscan-test, then use bscan to
884 restore the database, do a restore and compare with the
886 - Add restore of specific JobId to regression (item 3
887 on the restore prompt)
888 - Add IPv6 to regression
889 - Add database test to regression. Test each function like delete,
892 - AntiVir can slow down backups on Win32 systems.
893 - Win32 systems with FAT32 can be much slower than NTFS for
894 more than 1000 files per directory.
898 - A HOLD command to stop all jobs from starting.
899 - A PAUSE command to pause all running jobs ==> release the

903 Media Type Write = LTO2, LTO3
905 === From Carsten Menke <bootsy52@gmx.net>
907 Following is a list of what I think in the situations where I'm faced with,
908 could be a usefull enhancement to bacula, which I'm certain other users will
909 benefit from as well.
911 1. NextJob/NextJobs Directive within a Job Resource in the form of
912 NextJobs = job1,job2.
915 I currently solved the problem with running multiple jobs each after each
916 by setting the Max Wait Time for a job to 8 hours, and give
917 the jobs different Priorities. However, there scenarios where
918 1 Job is directly depending on another job, so if the former job fails,
919 the job after it needn't to be run
920 while maybe other jobs should run despite of that
923 A Backup Job and a Verify job, if the backup job fails there is no need to run
924 the verify job, as the backup job already failed. However, one may like
925 to backup the Catalog to disk despite of that the main backup job failed.
928 I see that this is related to the Event Handlers which are on the ToDo
929 list, also it is maybe a good idea to check for the return value and
930 execute different actions based on the return value
933 3. offline capability to bconsole
936 Currently I use a script which I execute within the last Job via the
937 RunAfterJob Directive, to release and eject the tape.
938 So I have to call bconsole "release=Storage-Name" and afterwards
939 mt -f /dev/nst0 eject to get the tape out.
941 If I have multiple Storage Devices, than these may not be /dev/nst0 and
942 I have to modify the script or call it with parameters etc.
943 This would actually not be needed, as everything is already defined
944 in bacula-sd.conf and if I can invoke bconsole with the
945 storage name via $1 in the script than I'm done and information is
948 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
952 For the reason mentioned in 3. to have the ability to call a
953 script with /scripts/foobar %s and in the script use $1
954 to pass the Storage Name to bconsole
956 5. Setting Volume State within a Job Resource
959 Instead of using "Maximum Volume Jobs" in the Pool Resource,
960 I would have the possibilty to define
961 in a Job Resource that after this certain job is run, the Volume State
962 should be set to "Volume State = Used", this give more flexibility (IMHO).
964 6. Localization of Bacula Messages
967 Unfortunatley many,many people I work with don't speak english very well.
968 So if at least the Reporting messages would be localized then they
969 would understand that they have to change the tape,etc. etc.
971 I volunteer to do the german translations, and if I can convince my wife also
972 french and Morre (western african language).
974 7. OK, this is evil, probably bound to security risks and maybe not possible
975 due to the design of bacula.
977 Implementation of Backtics ( `command` ) for shell comand execution to
978 the "Label Format" Directive.
982 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
983 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
984 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
985 the localized name for the day of the week appended to the
986 format string. Then I have the tape labeled automatically with weekday
987 name in the correct language.
989 - Make output from status use html table tags for nicely
990 presenting in a browser.
991 - Can one write tapes faster with 8192 byte block sizes?
992 - Document security problems with the same password for everyone in
993 rpm and Win32 releases.
994 - Browse generations of files.
995 - I've seen an error when my catalog's File table fills up. I
996 then have to recreate the File table with a larger maximum row
997 size. Relevant information is at
998 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
999 "Installing and Configuring MySQL" chapter should talk a bit
1000 about this potential problem, and recommend a solution.
1001 - For Solaris must use POSIX awk.
1002 - Want speed of writing to tape while despooling.
1003 - Supported autochanger:
1011 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
1012 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
1013 - Add regex from http://www.pcre.org to Bacula for Win32.
1014 - Use only shell tools no make in CDROM package.
1015 - Include within include does it work?
1016 - Implement a Pool of type Cleaning?
1017 - Implement VolReadTime and VolWriteTime in SD
1018 - Modify Backing up Your Database to include a bootstrap file.
1019 - Think about making certain database errors fatal.
1020 - Look at correcting the time jump in the scheduler for daylight
1021 savings time changes.
1022 - Add a "real" timer to network connections.
1023 - Promote to Full = Time period
1024 - Check dates entered by user for correctness (month/day/... ranges)
1025 - Compress restore Volume listing by date and first file.
1026 - Look at patches/bacula_db.b2z postgresql that loops during restore.
1028 - Perhaps add read/write programs and/or plugins to FileSets.
1029 - How to handle backing up portables ...
1030 - Add some sort of guaranteed Interval for upgrading jobs.
1031 - Can we write the state file after every job terminates? On Win32
1032 the system crashes and the state file is not updated.
1035 Documentation to do: (any release a little bit at a time)
1036 - Doc to do unmount before removing magazine.
1037 - Alternative to static linking "ldd prog" save all binaries listed,
1038 restore them and point LD_LIBRARY_PATH to them.
1039 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
1040 - Document query file format.
1041 - Add more documentation for bsr files.
1042 - Document problems with Verify and pruning.
1043 - Document how to use multiple databases.
1044 - VXA drives have a "cleaning required"
1045 indicator, but Exabyte recommends preventive cleaning after every 75
1048 In this context, it should be noted that Exabyte has a command-line
1049 vxatool utility available for free download. (The current version is
1050 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
1051 test the drive, unload tapes, change drive settings, flash new firmware,
1053 Of particular interest in this context is that vxatool <device> -i will
1054 report, among other details, the time since last cleaning in tape motion
1055 minutes. This information can be retrieved (and settings changed, for
1056 that matter) through the generic-SCSI device even when Bacula has the
1057 regular tape device locked. (Needless to say, I don't recommend
1058 changing tape settings while a job is running.)
1059 - Lookup HP cleaning recommendations.
1060 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
1061 - Document doing table repair
1064 ===================================
1065 - Add macro expansions in JobDefs.
1066 Run Before Job = "SomeFile %{Level} %{Client}"
1067 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
1068 - Use non-blocking network I/O but if no data is available, use
1070 - Use gather write() for network I/O.
1071 - Autorestart on crash.
1072 - Add bandwidth limiting.
1073 - Add acks every once and a while from the SD to keep
1074 the line from timing out.
1075 - When an error in input occurs and conio beeps, you can back
1076 up through the prompt.
1077 - Detect fixed tape block mode during positioning by looking at
1078 block numbers in btape "test". Possibly adjust in Bacula.
1079 - Fix list volumes to output volume retention in some other
1080 units, perhaps via a directive.
1081 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
1082 with multiple priorities.
1083 - If you use restore replace=never, the directory attributes for
1084 non-existent directories will not be restored properly.
1086 - see lzma401.zip in others directory for new compression
1088 - Allow the user to select JobType for manual pruning/purging.
1089 - bscan does not put first of two volumes back with all info in
1091 - Implement the FreeBSD nodump flag in chflags.
1092 - Figure out how to make named console messages go only to that
1093 console and to the non-restricted console (new console class?).
1094 - Make restricted console prompt for password if *ask* is set or
1095 perhaps if password is undefined.
1096 - Implement "from ISO-date/time every x hours/days/weeks/months" in
1099 ==== from Marc Schoechlin
1100 - the help-command should be more verbose
1101 (it should explain the paramters of the different
1103 -> its time-comsuming to consult the manual anytime
1104 you need a special parameter
1105 -> maybe its more easy to maintain this, if the
1106 descriptions of that commands are outsourced to
1108 - if the password is not configured in bconsole.conf
1109 you should be asked for it.
1110 -> sometimes you like to do restore on a customer-machine
1111 which shouldnt know the password for bacula.
1112 -> adding the password to the file favours admins
1113 to forget to remove the password after usage
1115 the protection of that file is less important
1116 - long-listed-output of commands should be scrollable
1117 like the unix more/less-command does
1118 -> if someone runs 200 and more machines, the lists could
1119 be a little long and complex
1120 - command-output should be shown column by column
1121 to reduce scrolling and to increase clarity
1123 - lsmark should list the selected files with full
1125 - wildcards for selecting and file and directories would be nice
1126 - any actions should be interuptable with STRG+C
1127 - command-expansion would be pretty cool
1129 - When the replace Never option is set, new directory permissions
1130 are not restored. See bug 213. To fix this requires creating a
1131 list of newly restored directories so that those directory
1132 permissions *can* be restored.
1133 - Add prune all command
1134 - Document fact that purge can destroy a part of a restore by purging
1135 one volume while others remain valid -- perhaps mark Jobs.
1136 - Add multiple-media-types.txt
1137 - look at mxt-changer.html
1138 - Make ? do a help command (no return needed).
1139 - Implement restore directory.
1140 - Document streams and how to implement them.
1141 - Try not to re-backup a file if a new hard link is added.
1142 - Add feature to backup hard links only, but not the data.
1143 - Fix stream handling to be simpler.
1144 - Add Priority and Bootstrap to Run a Job.
1145 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
1147 - Remove View FileSet button from Run a Job dialog.
1148 - Handle prompt for restore job at end of Restore command.
1149 - Add display of total selected files to Restore window.
1150 - Add tree pane to left of window.
1151 - Add progress meter.
1152 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
1153 - Add message to user to check for fixed block size when the forward
1154 space test fails in btape.
1155 - When unmarking a directory check if all files below are unmarked and
1156 then remove the + flag -- in the restore tree.
1157 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
1158 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
1159 - Revisit the question of multiple Volumes (disk) on a single device.
1160 - Add a block copy option to bcopy.
1161 - Finish work on Gnome restore GUI.
1162 - Fix "llist jobid=xx" where no fileset or client exists.
1163 - For each job type (Admin, Restore, ...) require only the really necessary
1164 fields.- Pass Director resource name as an option to the Console.
1165 - Add a "batch" mode to the Console (no unsolicited queries, ...).
1166 - Add a .list all files in the restore tree (probably also a list all files)
1167 Do both a long and short form.
1168 - Allow browsing the catalog to see all versions of a file (with
1169 stat data on each file).
1170 - Restore attributes of directory if replace=never set but directory
1172 - Use SHA1 on authentication if possible.
1173 - See comtest-xxx.zip for Windows code to talk to USB.
1174 - Add John's appended files:
1175 Appended = { /files/server/logs/http/*log }
1176 and such files would be treated as follows.On a FULL backup, they would
1177 be backed up like any other file.On an INCREMENTAL backup, where a
1178 previous INCREMENTAL or FULL was already in thecatalogue and the length
1179 of the file wasgreater than the length of the last backup, only thedata
1180 added since the last backup will be dumped.On an INCREMENTAL backup, if
1181 the length of the file is less than thelength of the file with the same
1182 name last backed up, the completefile is dumped.On Windows systems, with
1183 creation date of files, we can be evensmarter about this and not count
1184 entirely upon the length.On a restore, the full and all incrementals
1185 since it will beapplied in sequence to restore the file.
1186 - Check new HAVE_WIN32 open bits.
1187 - Check if the tape has moved before writing.
1188 - Handling removable disks -- see below:
1189 - Keep track of tape use time, and report when cleaning is necessary.
1190 - Add FromClient and ToClient keywords on restore command (or
1191 BackupClient RestoreClient).
1192 - Implement a JobSet, which groups any number of jobs. If the
1193 JobSet is started, all the jobs are started together.
1194 Allow Pool, Level, and Schedule overrides.
1195 - Enhance cancel to timeout BSOCK packets after a specific delay.
1196 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1197 ua_status.!!! Thanks to Alan Brown for this tip.
1198 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1199 correctly for multiple simultaneous jobs.
1200 - Correct code so that FileSet MD5 is calculated for < and | filename
1202 - Implement the Media record flag that indicates that the Volume does disk
1204 - Implement VolAddr, which is used when Volume is addressed like a disk,
1205 and form it from VolFile and VolBlock.
1206 - Make multiple restore jobs for multiple media types specifying
1207 the proper storage type.
1208 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1209 pointer (rec) to try_repositioning().
1210 - Look at extracting Win data from BackupRead.
1211 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1212 which would take precidence over the Catalog "JobRetention".
1213 - Implement Label Format in Add and Label console commands.
1214 - Possibly up network buffers to 65K. Put on variable.
1215 - Put email tape request delays on one or more variables. User wants
1216 to cancel the job after a certain time interval. Maximum Mount Wait?
1217 - Job, Client, Device, Pool, or Volume?
1218 Is it possible to make this a directive which is *optional* in multiple
1219 resources, like Level? If so, I think I'd make it an optional directive
1220 in Job, Client, and Pool, with precedence such that Job overrides Client
1221 which in turn overrides Pool.
1223 - New Storage specifications:
1224 - Want to write to multiple storage devices simultaneously
1225 - Want to write to multiple storage devices sequentially (in one job)
1226 - Want to read/write simultaneously
1227 - Key is MediaType -- it must match
1229 Passed to SD as a sort of BSR record called Storage Specification
1233 MediaType -> Next MediaType
1235 Device -> Next Device
1237 Allow multiple Storage specifications
1245 Allow Multiple Pool specifications (note, Pool currently
1247 Allow Multiple MediaType specifications in Dir conf
1248 Allow Multiple Device specifications in Dir conf
1249 Perhaps keep this in a single SSR
1250 Tie a Volume to a specific device by using a MediaType that
1251 is contained in only one device.
1252 In SD allow Device to have Multiple MediaTypes
1254 - Ideas from Jerry Scharf:
1255 First let's point out some big pluses that bacula has for this
1257 more importantly it's active. Thank you so much for that
1258 even more important, it's not flaky
1259 it has an open access catalog, opening many possibilities
1260 it's pushing toward heterogeneous systems capability
1262 Macintosh file client
1263 macs are an interesting niche, but I fear a server is a rathole
1264 working bare iron recovery for windows
1265 the option for inc/diff backups not reset on fileset revision
1266 a) use both change and inode update time against base time
1267 b) do the full catalog check (expensive but accurate)
1268 sizing guide (how much system is needed to back up N systems/files)
1269 consultants on using bacula in building a disaster recovery system
1270 an integration guide
1271 or how to get at fancy things that one could do with bacula
1272 logwatch code for bacula logs (or similar)
1273 linux distro inclusion of bacula (brings good and bad, but necessary)
1274 win2k/XP server capability (icky but you asked)
1275 support for Oracle database ??
1277 - Look at adding SQL server and Exchange support for Windows.
1278 - Make dev->file and dev->block_num signed integers so that -1 can
1279 be an invalid value which happens with BSR.
1280 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1281 is needed to properly specify ranges.
1282 - Add progress of files/bytes to SD and FD.
1283 - Print warning message if FileId > 4 billion
1284 - do a "messages" before the first prompt in Console
1285 - Client does not show busy during Estimate command.
1286 - Implement Console mtx commands.
1287 - Implement a Mount Command and an Unmount Command where
1288 the users could specify a system command to be performed
1289 to do the mount, after which Bacula could attempt to
1290 read the device. This is for Removeable media such as a CDROM.
1291 - Most likely, this mount command would be invoked explicitly
1292 by the user using the current Console "mount" and "unmount"
1293 commands -- the Storage Daemon would do the right thing
1294 depending on the exact nature of the device.
1295 - As with tape drives, when Bacula wanted a new removable
1296 disk mounted, it would unmount the old one, and send a message
1297 to the user, who would then use "mount" as described above
1298 once he had actually inserted the disk.
1299 - Implement dump/print label to UA
1300 - Spool to disk only when the tape is full, then when a tape is hung move
1302 - bextract is sending everything to the log file ****FIXME****
1303 - Allow multiple Storage specifications (or multiple names on
1304 a single Storage specification) in the Job record. Thus a job
1305 can be backed up to a number of storage devices.
1306 - Implement some way for the File daemon to contact the Director
1307 to start a job or pass its DHCP obtained IP number.
1308 - Implement a query tape prompt/replace feature for a console
1309 - Copy console @ code to gnome2-console
1310 - Make sure that Bacula rechecks the tape after the 20 min wait.
1311 - Set IO_NOWAIT on Bacula TCP/IP packets.
1312 - Try doing a raw partition backup and restore by mounting a
1314 - From Lars Kellers:
1315 Yes, it would allow to highly automatic the request for new tapes. If a
1316 tape is empty, bacula reads the barcodes (native or simulated), and if
1317 an unused tape is found, it runs the label command with all the
1318 necessary parameters.
1320 By the way can bacula automatically "move" an empty/purged volume say
1321 in the "short" pool to the "long" pool if this pool runs out of volume
1323 - What to do about "list files job=xxx".
1324 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1325 file descriptor leak in Bacula.
1326 - Implement WrapCounters in Counters.
1327 - Add heartbeat from FD to SD if hb interval expires.
1328 - Can we dynamically change FileSets?
1329 - If pool specified to label command and Label Format is specified,
1330 automatically generate the Volume name.
1331 - Why can't SQL do the filename sort for restore?
1332 - Add ExhautiveRestoreSearch
1333 - Look at the possibility of loading only the necessary
1334 data into the restore tree (i.e. do it one directory at a
1335 time as the user walks through the tree).
1336 - Possibly use the hash code if the user selects all for a restore command.
1337 - Fix "restore all" to bypass building the tree.
1338 - Prohibit backing up archive device (findlib/find_one.c:128)
1339 - Implement Release Device in the Job resource to unmount a drive.
1340 - Implement Acquire Device in the Job resource to mount a drive,
1341 be sure this works with admin jobs so that the user can get
1342 prompted to insert the correct tape. Possibly some way to say to
1343 run the job but don't save the files.
1344 - Make things like list where a file is saved case independent for
1346 - Use autochanger to handle multiple devices.
1347 - Implement a Recycle command
1348 - Start working on Base jobs.
1349 - Implement UnsavedFiles DB record.
1350 - From Phil Stracchino:
1351 It would probably be a per-client option, and would be called
1352 something like, say, "Automatically purge obsoleted jobs". What it
1353 would do is, when you successfully complete a Differential backup of a
1354 client, it would automatically purge all Incremental backups for that
1355 client that are rendered redundant by that Differential. Likewise,
1356 when a Full backup on a client completed, it would automatically purge
1357 all Differential and Incremental jobs obsoleted by that Full backup.
1358 This would let people minimize the number of tapes they're keeping on
1359 hand without having to master the art of retention times.
1360 - When doing a Backup send all attributes back to the Director, who
1361 would then figure out what files have been deleted.
1362 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1363 explicit permission to do so. It should also mark the tape in error
1364 if there is an error.
1365 - Cancel waiting for Client connect in SD if FD goes away.
1367 - Implement timeout in response() when it should come quickly.
1368 - Implement a Slot priority (loaded/not loaded).
1369 - Implement "vacation" Incremental only saves.
1370 - Implement create "FileSet"?
1371 - Add prefixlinks to where or not where absolute links to FD.
1372 - Issue message to mount a new tape before the rewind.
1373 - Simplified client job initiation for portables.
1374 - If SD cannot open a drive, make it periodically retry.
1375 - Add more of the config info to the tape label.
1377 - Refine SD waiting output:
1378 Device is being positioned
1379 > Device is being positioned for append
1380 > Device is being positioned to file x
1382 - Figure out some way to estimate output size and to avoid splitting
1383 a backup across two Volumes -- this could be useful for writing CDROMs
1384 where you really prefer not to have it split -- not serious.
1385 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1386 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1387 actual data on the Volume and compare it.
1388 - Make bcopy read through bad tape records.
1389 - Program files (i.e. execute a program to read/write files).
1390 Pass read date of last backup, size of file last time.
1391 - Add Signature type to File DB record.
1392 - CD into subdirectory when open()ing files for backup to
1393 speed up things. Test with testfind().
1394 - Priority job to go to top of list.
1395 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1396 - Implement some way for the Console to dynamically create a job.
1397 - Solaris -I on tar for include list
1398 - Need a verbose mode in restore, perhaps to bsr.
1399 - bscan without -v is too quiet -- perhaps show jobs.
1400 - Add code to reject whole blocks if not wanted on restore.
1401 - Check if we can increase Bacula FD priorty in Win2000
1402 - Make sure the MaxVolFiles is fully implemented in SD
1403 - Check if both CatalogFiles and UseCatalog are set to SD.
1404 - Possibly add email to Watchdog if drive is unmounted too
1405 long and a job is waiting on the drive.
1406 - After unmount, if restore job started, ask to mount.
1407 - Add UA rc and history files.
1408 - put termcap (used by console) in ./configure and
1409 allow -with-termcap-dir.
1410 - Fix Autoprune for Volumes to respect need for full save.
1411 - Compare tape to Client files (attributes, or attributes and data)
1412 - Make all database Ids 64 bit.
1413 - Allow console commands to detach or run in background.
1414 - Add SD message variables to control operator wait time
1415 - Maximum Operator Wait
1416 - Minimum Message Interval
1417 - Maximum Message Interval
1418 - Send Operator message when cannot read tape label.
1419 - Verify level=Volume (scan only), level=Data (compare of data to file).
1420 Verify level=Catalog, level=InitCatalog
1422 - Add keyword search to show command in Console.
1423 - Events : tape has more than xxx bytes.
1424 - Complete code in Bacula Resources -- this will permit
1425 reading a new config file at any time.
1426 - Handle ctl-c in Console
1427 - Implement script driven addition of File daemon to config files.
1428 - Think about how to make Bacula work better with File (non-tape) archives.
1429 - Write Unix emulator for Windows.
1430 - Put memory utilization in Status output of each daemon
1431 if full status requested or if some level of debug on.
1432 - Make database type selectable by .conf files i.e. at runtime
1433 - Set flag for uname -a. Add to Volume label.
1434 - Restore files modified after date
1435 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1436 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1437 - Timout a job or terminate if link goes down, or reopen link and query.
1438 - Concept of precious tapes (cannot be reused).
1439 - Make bcopy copy with a single tape drive.
1440 - Permit changing ownership during restore.

1454 - Autolabel should be specified by DIR instead of SD.
1456 - Add media capacity
1457 - AutoScan (check checksum of tape)
1458 - Format command = "format /dev/nst0"
1462 - Seek resolution (usually corresponds to buffer size)
1463 - EODErrorCode=ENOSPC or code
1464 - Partial Read error code
1465 - Partial write error code
1466 - Nonformatted read error
1467 - Nonformatted write error
1468 - WriteProtected error
1472 - IgnoreCloseErrors=yes
1482 - FD sends unsaved file list to Director at end of job (see
1484 - File daemon should build list of files skipped, and then
1485 at end of save retry and report any errors.
1486 - Write a Storage daemon that uses pipes and
1487 standard Unix programs to write to the tape.
1489 - Need something that monitors the JCR queue and
1490 times out jobs by asking the deamons where they are.
1491 - Enhance Jmsg code to permit buffering and saving to disk.
1492 - device driver = "xxxx" for drives.
1493 - Verify from Volume
1494 - Ensure that /dev/null works
1495 - Need report class for messages. Perhaps
1496 report resource where report=group of messages
1497 - enhance scan_attrib and rename scan_jobtype, and
1498 fill in code for "since" option
1499 - Director needs a time after which the report status is sent
1500 anyway -- or better yet, a retry time for the job.
1501 - Don't reschedule a job if previous incarnation is still running.
1502 - Some way to automatically backup everything is needed????
1503 - Need a structure for pending actions:
1505 - termination status (part of buffered msgs?)
1507 Read, Write, Clean, Delete
1508 - Login to Bacula; Bacula users with different permissions:
1509 owner, group, user, quotas
1510 - Store info on each file system type (probably in the job header on tape.
1511 This could be the output of df; or perhaps some sort of /etc/mtab record.
1513 ========= ideas ===============
1514 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1515 To: <kern@sibbald.com>
1516 Subject: RE: [Bacula-users] future large programming jobs
1517 Date: Thu, 26 Feb 2004 11:34:54 -0600
1519 I noticed the subject thread and thought I would offer the following
1520 merely as sources of ideas, i.e. something to think about, not even as
1521 strong as a request. In my former life (before retiring) I often
1522 dealt with backups and storage management issues/products as a
1523 developer and as a consultant. I am currently migrating my personal
1524 network from amanda to bacula specifically because of the ability to
1525 cross media boundaries during storing backups.
1526 Are you familiar with the commercial product called ADSM (I think IBM
1527 now sells it under the Tivoli label)? It has a couple of interesting
1528 ideas that may apply to the following topics.
1530 1. Migration: Consider that when you need to restore a system, there
1531 may be pressure to hurry. If all the information for a single client
1532 can eventually end up on the same media (and in chronological order),
1533 the restore is facillitated by not having to search past information
1534 from other clients. ADSM has the concept of "client affinity" that
1535 may be associated with it's storage pools. It seems to me that this
1536 concept (as an optional feature) might fit in your architecture for
1539 ADSM also has the concept of defining one or more storage pools as
1540 "copy pools" (almost mirrors, but only in the sense of contents).
1541 These pools provide the ability to have duplicte data stored both
1542 onsite and offsite. The copy process can be scheduled to be handled
1543 by their storage manager during periods when there is no backup
1544 activity. Again, the migration process might be a place to consider
1545 implementing something like this.
1548 > It strikes me that it would be very nice to be able to do things
1550 > have the Job(s) backing up the machines run, and once they have all

1556 > mechanism described below would probably make it very easy.
1558 This is the goal. In the first step (before events), you simply
1560 the Migration to tape later.
1562 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1563 the database. Once a file (unique by path and metadata such as dates,
1564 size, ownership, etc.) is in a copy pool, no more copies are made. In
1565 other words, when you start ADSM, it begins like your concept of a
1566 base job. After that it is in the "incremental" mode. You can
1567 configure the number of "generations" of files to be retained, plus a
1568 retention date after which even old generations are purged. The
1569 database tracks the contents of media and projects the percentage of
1570 each volume that is valid. When the valid content of a volume drops
1571 below a configured percentage, the valid data are migrated to another
1572 volume and the old volume is marked as empty. Note, this requires
1573 ADSM to have an idea of the contents of a client, i.e. marking the
1574 database when an existing file was deleted, but this would solve your
1575 issue of restoring a client without restoring deleted files.
1577 This is pretty far from what bacula now does, but if you are going to
1578 rip things up for Base jobs,.....
1579 Also, the benefits of this are huge for very large shops, especially
1580 with media robots, but are a pain for shops with manual media
1584 > Base jobs sound pretty useful, but I'm not dying for them.
1586 Nobody is dying for them, but when you see what it does, you will die
1589 3. Restoring deleted files: Since I think my comments in (2) above
1590 have low probability of implementation, I'll also suggest that you
1591 could approach the issue of deleted files by a mechanism of having the
1592 fd report to the dir, a list of all files on the client for every
1593 backup job. The dir could note in the database entry for each file
1594 the date that the file was seen. Then if a restore as of date X takes
1595 place, only files that exist from before X until after X would be
1596 restored. Probably the major cost here is the extra date container in
1597 each row of the files table.
1599 Thanks for "listening". I hope some of this helps. If you want to
1600 contact me, please send me an email - I read some but not all of the
1601 mailing list traffic and might miss a reply there.
1603 Please accept my compliments for bacula. It is doing a great job for
1604 me!! I sympathize with you in the need to wrestle with excelence in
1605 execution vs. excelence in feature inclusion.
1610 ==============================
1613 - Design at hierarchial storage for Bacula. Migration and Clone.
1614 - Implement FSM (File System Modules).
1615 - Audit M_ error codes to ensure they are correct and consistent.
1616 - Add variable break characters to lex analyzer.
1617 Either a bit mask or a string of chars so that
1618 the caller can change the break characters.
1619 - Make a single T_BREAK to replace T_COMMA, etc.
1620 - Ensure that File daemon and Storage daemon can
1621 continue a save if the Director goes down (this
1622 is NOT currently the case). Must detect socket error,
1623 buffer messages for later.
1624 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1625 - Add ability to backup to two Storage devices (two SD sessions) at
1626 the same time -- e.g. onsite, offsite.
1627 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1628 someway to do so with every volume that has less than x% valid
1632 Migration: Move a backup from one Volume to another
1633 Clone: Copy a backup -- two Volumes
1636 ======================================================
1638 It is somewhat like a Full save becomes an incremental since
1639 the Base job (or jobs) plus other non-base files.
1641 - A Base backup is same as Full backup, just different type.
1642 - New BaseFiles table that contains:
1644 BaseJobId - Base JobId referenced for this FileId (needed ???)
1645 JobId - JobId currently running
1646 FileId - File not backed up, exists in Base Job
1647 FileIndex - FileIndex from Base Job.
1648 i.e. for each base file that exists but is not saved because
1649 it has not changed, the File daemon sends the JobId, BaseId,
1650 FileId, FileIndex back to the Director who creates the DB entry.
1651 - To initiate a Base save, the Director sends the FD
1652 the FileId, and full filename for each file in the Base.
1653 - When the FD finds a Base file, he requests the Director to
1654 send him the full File entry (stat packet plus MD5), or
1655 conversely, the FD sends it to the Director and the Director
1656 says yes or no. This can be quite rapid if the FileId is kept
1657 by the FD for each Base Filename.
1658 - It is probably better to have the comparison done by the FD
1659 despite the fact that the File entry must be sent across the
1661 - An alternative would be to send the FD the whole File entry
1662 from the start. The disadvantage is that it requires a lot of
1663 space. The advantage is that it requires less communications
1665 - The Job record must be updated to indicate that one or more
1667 - At end of Job, FD returns:
1668 1. Count of base files/bytes not written to tape (i.e. matches)
1669 2. Count of base file that were saved i.e. had changed.
1670 - No tape record would be written for a Base file that matches, in the
1671 same way that no tape record is written for Incremental jobs where
1672 the file is not saved because it is unchanged.
1673 - On a restore, all the Base file records must explicitly be
1674 found from the BaseFile tape. I.e. for each Full save that is marked
1675 to have one or more Base Jobs, search the BaseFile for all occurrences
1677 - An optimization might be to make the BaseFile have:
1683 This would avoid the need to explicitly fetch each File record for
1684 the Base job. The Base Job record will be fetched to get the
1685 VolSessionId and VolSessionTime.

1726 Unloading Data Transfer Element into Storage Element 15...done
1728 (just to verify it remembers where it came from, however it can be
1729 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1731 There needs to be a table of drive # to devices somewhere - If there are
1732 multiple changers or drives there may not be a 1:1 correspondance between
1733 changer drive number and system device name - and depending on the way the
1734 drives are hooked up to scsi busses, they may not be linearly numbered
1735 from an offset point either.something like
1737 Autochanger drives = 2
1738 Autochanger drive 0 = /dev/nst1
1739 Autochanger drive 1 = /dev/nst2
1740 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1741 times, not just for multidrive changers. For a 1 drive changer, that's
1747 MTX's manpage (1.2.15):
1748 unload [<slotnum>] [ <drivenum> ]
1749 Unloads media from drive <drivenum> into slot
1750 <slotnum>. If <drivenum> is omitted, defaults to
1751 drive 0 (as do all commands). If <slotnum> is
1752 omitted, defaults to the slot that the drive was
1753 loaded from. Note that there's currently no way
1754 to say 'unload drive 1's media to the slot it
1755 came from', other than to explicitly use that
1756 slot number as the destination.AB

1794 Handling removable disks
1796 From: Karl Cunningham <karlc@keckec.com>
1798 My backups are only to hard disk these days, in removable bays. This is my
1799 idea of how a backup to hard disk would work more smoothly. Some of these
1800 things Bacula does already, but I mention them for completeness. If others
1801 have better ways to do this, I'd like to hear about it.
1803 1. Accommodate several disks, rotated similar to how tapes are. Identified
1804 by partition volume ID or perhaps by the name of a subdirectory.
1805 2. Abort & notify the admin if the wrong disk is in the bay.
1806 3. Write backups to different subdirectories for each machine to be backed
1808 4. Volumes (files) get created as needed in the proper subdirectory, one
1810 5. When a disk is recycled, remove or zero all old backup files. This is
1811 important as the disk being recycled may be close to full. This may be
1812 better done manually since the backup files for many machines may be
1813 scattered in many subdirectories.
1818 - Why the heck doesn't bacula drop root priviledges before connecting to
1820 - Look at using posix_fadvise(2) for backups -- see bug #751.
1821 Possibly add the code at findlib/bfile.c:795
1822 /* TCP socket options */
1823 #define TCP_KEEPIDLE 4 /* Start keeplives after this period */
1824 - Fix bnet_connect() code to set a timer and to use time to
1826 - Implement 4th argument to make_catalog_backup that passes hostname.
1827 - Test FIFO backup/restore -- make regression
1828 - Please mount volume "xxx" on Storage device ... should also list
1829 Pool and MediaType in case user needs to create a new volume.
1830 - On restore add Restore Client, Original Client.

1839 - Check if gnome-console works with TLS.
1840 - the director seg faulted when I omitted the pool directive from a
1841 job resource. I was experimenting and thought it redundant that I had
1842 specified Pool, Full Backup Pool. and Differential Backup Pool. but
1843 apparently not. This happened when I removed the pool directive and
1844 started the director.
1845 - Add Where: client:/.... to restore job report.
1846 - Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
1847 does the right thing.
1848 - FD-SD quick disconnect
1849 - Building the in memory restore tree is slow.
1850 - Erabt if min_block_size > max_block_size
1851 - Add the ability to consolidate old backup sets (basically do a restore
1852 to tape and appropriately update the catalog). Compress Volume sets.
1853 Might need to spool via file is only one drive is available.
1854 - Why doesn't @"xxx abc" work in a conf file?
1855 - Don't restore Solaris Door files:
1856 #define S_IFDOOR in st_mode.
1857 see: http://docs.sun.com/app/docs/doc/816-5173/6mbb8ae23?a=view#indexterm-360
1858 - Figure out how to recycle Scratch volumes back to the Scratch Pool.
1859 - Implement Despooling data status.
1860 - Use E'xxx' to escape PostgreSQL strings.
1861 - Look at mincore: http://insights.oetiker.ch/linux/fadvise.html
1862 - Unicode input http://en.wikipedia.org/wiki/Byte_Order_Mark
1863 - Look at moving the Storage directive from the Job to the
1864 Pool in the default conf files.
1865 - Look at in src/filed/backup.c
1866 > pm_strcpy(ff_pkt->fname, ff_pkt->fname_save);
1867 > pm_strcpy(ff_pkt->link, ff_pkt->link_save);
1868 - Add Catalog = to Pool resource so that pools will exist
1869 in only one catalog -- currently Pools are "global".
1870 - Add TLS to bat (should be done).
1871 === Duplicate jobs ===
1872 - Done, but implemented somewhat differently than described below!!!
1874 hese apply only to backup jobs.
1876 1. Allow Duplicate Jobs = Yes | No | Higher (Yes)
1878 2. Duplicate Job Interval = <time-interval> (0)
1880 The defaults are in parenthesis and would produce the same behavior as today.
1882 If Allow Duplicate Jobs is set to No, then any job starting while a job of the
1883 same name is running will be canceled.
1885 If Allow Duplicate Jobs is set to Higher, then any job starting with the same
1886 or lower level will be canceled, but any job with a Higher level will start.
1887 The Levels are from High to Low: Full, Differential, Incremental
1889 Finally, if you have Duplicate Job Interval set to a non-zero value, any job
1890 of the same name which starts <time-interval> after a previous job of the
1891 same name would run, any one that starts within <time-interval> would be
1892 subject to the above rules. Another way of looking at it is that the Allow
1893 Duplicate Jobs directive will only apply after <time-interval> of when the
1894 previous job finished (i.e. it is the minimum interval between jobs).
1898 Allow Duplicate Jobs = Yes | No | HigherLevel | CancelLowerLevel (Yes)
1900 Where HigherLevel cancels any waiting job but not any running job.
1901 Where CancelLowerLevel is same as HigherLevel but cancels any running job or
1904 Duplicate Job Proximity = <time-interval> (0)
1906 My suggestion was to define it as the minimum guard time between
1907 executions of a specific job -- ie, if a job was scheduled within Job
1908 Proximity number of seconds, it would be considered a duplicate and
1911 Skip = Do not allow two or more jobs with the same name to run
1912 simultaneously within the proximity interval. The second and subsequent
1913 jobs are skipped without further processing (other than to note the job
1914 and exit immediately), and are not considered errors.
1916 Fail = The second and subsequent jobs that attempt to run during the
1917 proximity interval are cancelled and treated as error-terminated jobs.
1919 Promote = If a job is running, and a second/subsequent job of higher
1920 level attempts to start, the running job is promoted to the higher level
1921 of processing using the resources already allocated, and the subsequent
1922 job is treated as in Skip above.
1928 Allow = yes|no (no = default)
1930 AllowHigherLevel = yes|no (no)
1932 AllowLowerLevel = yes|no (no)
1934 AllowSameLevel = yes|no
1936 Cancel = Running | New (no)
1938 CancelledStatus = Fail | Skip (fail)
1940 Job Proximity = <time-interval> (0)
1941 My suggestion was to define it as the minimum guard time between
1942 executions of a specific job -- ie, if a job was scheduled within Job
1943 Proximity number of seconds, it would be considered a duplicate and
1949 - Fix bpipe.c so that it does not modify results pointer.
1950 ***FIXME*** calling sequence should be changed.
