38 - Check "update slots=7 scan storage=DLT drive=0" with
39 non-bacula tape in the drive.
41 - --without-openssl breaks at least on Solaris.
42 - Arno had to do -- to get update slots=x to work
43 UPDATE Media SET InChanger=0,Slot=0 WHERE InChanger>0 AND Slot>0; (MySQL)
46 - Does ClientRunAfterJob fail the job on a bad return code?
47 - Document cleaning up the spool files:
48 db, pid, state, bsr, mail, conmsg, spool
49 - Document the multiple-drive-changer.txt script.
50 - Pruning with Admin job.
51 - Does WildFile match against full name? Doc.
54 - Add binary tree search for tree routines.
55 - Add a new Autochanger directive "Global lock = yes|no"
56 that provides a global lock on calling mtx-changer so
57 that multiple autochanger definitions can reference
58 the same physical autochanger.
59 - Look at -D_FORTIFY_SOURCE=2
60 - Close STDOUT if debug_level == 0
62 - Add scratch pool event.
63 - Implement NeedVolume event
64 - Add Win32 FileSet definition somewhere
65 - Look at fixing restore status stats in SD.
66 - Make selection of Database used in restore correspond to
68 - implement a mode that says when a hard read error is
69 encountered, read many times (as it currently does), and if the
70 block cannot be read, skip to the next block, and try again. If
71 that fails, skip to the next file and try again, ...
72 - Add ACL to restore only to original location.
73 - Add a recursive mark command (rmark) to restore.
74 - "Minimum Job Interval = nnn" sets minimum interval between Jobs
75 of the same level and does not permit multiple simultaneous
76 running of that Job (i.e. lets any previous invocation finish
77 before doing Interval testing).
78 - Look at simplifying File exclusions.
79 - Fix store_yesno to be store_bitmask.
80 - New directive "Delete purged Volumes"
81 - new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
82 let it fill itself, and RecyclePoolId = XXX's PoolId so I can
83 see if it become stable and I just have to supervise
85 - If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
86 PoolId, and when it is empty remove it.
87 - Figure out how to recycle Scratch volumes back to the Scratch
90 - Allow Check Labels to be used with Bacula labels.
91 - "Resuming" a failed backup (lost line for example) by using the
92 failed backup as a sort of "base" job.
94 - Email to the user when the tape is about to need changing x
95 days before it needs changing.
96 - Command to show next tape that will be used for a job even
97 if the job is not scheduled.

110 1. When jobs are running and bacula for some reason crashes or if I do a
111 restart it remembers and jobs it was running before it crashed or restarted
112 as of now I loose all jobs if I restart it.
114 2. When spooling and in the midway if client is disconnected for instance a
115 laptop bacula completely discard the spool. It will be nice if it can write
116 that spool to tape so there will be some backups for that client if not all.
118 3. We have around 150 clients machines it will be nice to have a option to
119 upgrade all the client machines bacula version automatically.
121 4. Atleast one connection should be reserved for the bconsole so at heavy load
122 I should connect to the director via bconsole which at sometimes I can't
124 5. Another most important feature that is missing, say at 10am I manually
125 started backup of client abc and it was a full backup since client abc has
126 no backup history and at 10.30am bacula again automatically started backup of
127 client abc as that was in the schedule. So now we have 2 multiple Full
128 backups of the same client and if we again try to start a full backup of
129 client backup abc bacula won't complain. That should be fixed.
131 - Fix bpipe.c so that it does not modify results pointer.
132 ***FIXME*** calling sequence should be changed.
134 #3 Migration (Move, Copy, Archive Jobs)
135 #7 Single Job Writing to Multiple Storage Devices
136 - Reserve blocks other restore jobs when first cannot connect
138 - Add true/false to conf same as yes/no
139 - For Windows disaster recovery see http://unattended.sf.net/
140 - regardless of the retention period, Bacula will not prune the
141 last Full, Diff, or Inc File data until a month after the
142 retention period for the last Full backup that was done.
143 - update volume=xxx --- add status=Full
144 - Remove old spool files on startup.
145 - Exclude SD spool/working directory.
146 - Refuse to prune last valid Full backup. Same goes for Catalog.
148 - Make a callback when Rerun failed levels is called.
149 - Give Python program access to Scheduled jobs.
150 - Add setting Volume State via Python.
151 - Python script to save with Python, not save, save with Bacula.
152 - Python script to do backup.
154 - Change the Priority, Client, Storage, JobStatus (error)
155 at the start of a job.
156 - Why is SpoolDirectory = /home/bacula/spool; not reported
157 as an error when writing a DVD?
158 - Make bootstrap file handle multiple MediaTypes (SD)
159 - Remove all old Device resource code in Dir and code to pass it
160 back in SD -- better, rework it to pass back device statistics.
161 - Check locking of resources -- be sure to lock devices where previously
162 resources were locked.
163 - The last part is left in the spool dir.
166 - In restore don't compare byte count on a raw device -- directory
167 entry does not contain bytes.
168 - To mark files as deleted, run essentially a Verify to disk, and
169 when a file is found missing (MarkId != JobId), then create
170 a new File record with FileIndex == -1. This could be done
171 by the FD at the same time as the backup.
175 MA = (last_MA * 3 + rate) / 4
176 rate = (bytes - last_bytes) / (runtime - last_runtime)
177 - Max Vols limit in Pool off by one?
178 - Implement Files/Bytes,... stats for restore job.
179 - Implement Total Bytes Written, ... for restore job.
180 - Despool attributes simultaneously with data in a separate
181 thread, rejoined at end of data spooling.
182 - 7. Implement new Console commands to allow offlining/reserving drives,
183 and possibly manipulating the autochanger (much asked for).
184 - Add start/end date editing in messages (%t %T, %e?) ...
185 - Add ClientDefs similar to JobDefs.
186 - Print more info when bextract -p accepts a bad block.
187 - Fix FD JobType to be set before RunBeforeJob in FD.
188 - Look at adding full Volume and Pool information to a Volume
189 label so that bscan can get *all* the info.
190 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
191 and there is only one volume in the pool, refuse to do it -- otherwise
192 he fills the Volume, then immediately starts reusing it.
193 - Implement copies and stripes.
194 - Add history file to console.
195 - Each file on tape creates a JobMedia record. Peter has 4 million
196 files spread over 10000 tape files and four tapes. A restore takes
197 16 hours to build the restore list.
198 - Add and option to check if the file size changed during backup.
199 - Make sure SD deletes spool files on error exit.
200 - Delete old spool files when SD starts.
201 - When labeling tapes, if you enter 000026, Bacula uses
202 the tape index rather than the Volume name 000026.
203 - Add offline tape command to Bacula console.
205 Enter MediaId or Volume name: 32
206 Enter new Volume name: DLT-20Dec04
207 Automatically selected Pool: Default
208 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...

211 Error writing final EOF to tape. This tape may not be readable.
212 dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
213 askdir.c:219 NULL Volume name. This shouldn't happen!!!
214 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
215 Label command failed for Volume DLT-20Dec04.
216 Do not forget to mount the drive!!!
217 - Bug: if a job is manually scheduled to run later, it does not appear
218 in any status report and cannot be cancelled.
220 ==== Keeping track of deleted files ====
221 My "trick" for keeping track of deletions is the following.
222 Assuming the user turns on this option, after all the files
223 have been backed up, but before the job has terminated, the
224 FD will make a pass through all the files and send their
225 names to the DIR (*exactly* the same as what a Verify job
226 currently does). This will probably be done at the same
227 time the files are being sent to the SD avoiding a second
228 pass. The DIR will then compare that to what is stored in
229 the catalog. Any files in the catalog but not in what the
230 FD sent will receive a catalog File entry that indicates
231 that at that point in time the file was deleted.
233 During a restore, any file initially picked up by some
234 backup (Full, ...) then subsequently having a File entry
235 marked "delete" will be removed from the tree, so will not
236 be restored. If a file with the same name is later OK it
237 will be inserted in the tree -- this already happens. All
238 will be consistent except for possible changes during the
241 Since I'm on the subject, some of you may be wondering what
242 the utility of the in memory tree is if you are going to
243 restore everything (at least it comes up from time to time
244 on the list). Well, it is still *very* useful because it
245 allows only the last item found for a particular filename
246 (full path) to be entered into the tree, and thus if a file
247 is backed up 10 times, only the last copy will be restored.
248 I recently (last Friday) restored a complete directory, and
249 the Full and all the Differential and Incremental backups
250 spanned 3 Volumes. The first Volume was not even mounted
251 because all the files had been updated and hence backed up
252 since the Full backup was made. In this case, the tree
253 saved me a *lot* of time.
255 Make sure this information is stored on the tape too so
256 that it can be restored directly from the tape.
258 Comments from Martin Simmons (I think they are all covered):
259 Ok, that should cover the basics. There are few issues though:
261 - Restore will depend on the catalog. I think it is better to include the
262 extra data in the backup as well, so it can be seen by bscan and bextract.
264 - I'm not sure if it will preserve multiple hard links to the same inode. Or
265 maybe adding or removing links will cause the data to be dumped again?
267 - I'm not sure if it will handle renamed directories. Possibly it will work
268 by dumping the whole tree under a renamed directory?
270 - It remains to be seen how the backup performance of the DIR's will be
271 affected when comparing the catalog for a large filesystem.
276 - Add Pool/Storage override regression test.
277 - Add delete JobId to regression.
278 - Add a regression test for dbcheck.
279 - New test to add bscan to four-concurrent-jobs regression,
280 i.e. after the four-concurrent jobs zap the
281 database as is done in the bscan-test, then use bscan to
282 restore the database, do a restore and compare with the
284 - Add restore of specific JobId to regression (item 3
285 on the restore prompt)
286 - Add IPv6 to regression
287 - Add database test to regression. Test each function like delete,
290 - AntiVir can slow down backups on Win32 systems.
291 - Win32 systems with FAT32 can be much slower than NTFS for
292 more than 1000 files per directory.
296 - A HOLD command to stop all jobs from starting.
297 - A PAUSE command to pause all running jobs ==> release the
299 - Media Type = LTO,LTO-2,LTO-3
300 Media Type Read = LTO,LTO2,LTO3
301 Media Type Write = LTO2, LTO3
303 === From Carsten Menke <bootsy52@gmx.net>
305 Following is a list of what I think in the situations where I'm faced with,
306 could be a usefull enhancement to bacula, which I'm certain other users will
307 benefit from as well.
309 1. NextJob/NextJobs Directive within a Job Resource in the form of
310 NextJobs = job1,job2.
313 I currently solved the problem with running multiple jobs each after each
314 by setting the Max Wait Time for a job to 8 hours, and give
315 the jobs different Priorities. However, there scenarios where
316 1 Job is directly depending on another job, so if the former job fails,
317 the job after it needn't to be run
318 while maybe other jobs should run despite of that
321 A Backup Job and a Verify job, if the backup job fails there is no need to run
322 the verify job, as the backup job already failed. However, one may like
323 to backup the Catalog to disk despite of that the main backup job failed.
326 I see that this is related to the Event Handlers which are on the ToDo
327 list, also it is maybe a good idea to check for the return value and
328 execute different actions based on the return value
331 3. offline capability to bconsole
334 Currently I use a script which I execute within the last Job via the
335 RunAfterJob Directive, to release and eject the tape.
336 So I have to call bconsole "release=Storage-Name" and afterwards
337 mt -f /dev/nst0 eject to get the tape out.
339 If I have multiple Storage Devices, than these may not be /dev/nst0 and
340 I have to modify the script or call it with parameters etc.
341 This would actually not be needed, as everything is already defined
342 in bacula-sd.conf and if I can invoke bconsole with the
343 storage name via $1 in the script than I'm done and information is
346 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
350 For the reason mentioned in 3. to have the ability to call a
351 script with /scripts/foobar %s and in the script use $1
352 to pass the Storage Name to bconsole
354 5. Setting Volume State within a Job Resource
357 Instead of using "Maximum Volume Jobs" in the Pool Resource,
358 I would have the possibilty to define
359 in a Job Resource that after this certain job is run, the Volume State
360 should be set to "Volume State = Used", this give more flexibility (IMHO).
362 6. Localization of Bacula Messages
365 Unfortunatley many,many people I work with don't speak english very well.
366 So if at least the Reporting messages would be localized then they
367 would understand that they have to change the tape,etc. etc.
369 I volunteer to do the german translations, and if I can convince my wife also
370 french and Morre (western african language).
372 7. OK, this is evil, probably bound to security risks and maybe not possible
373 due to the design of bacula.
375 Implementation of Backtics ( `command` ) for shell comand execution to
376 the "Label Format" Directive.
380 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
381 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
382 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
383 the localized name for the day of the week appended to the
384 format string. Then I have the tape labeled automatically with weekday
385 name in the correct language.
387 - Yes, that is surely the case. I probably should turn those into Warning
388 errors. In addition, you just made me think that it might not be bad to
389 add an option to check the file size after backing up the file and
390 report if it changes. This would be done as an option because it would
393 Kern, good idea. If you do do that, mention in the output: file
394 shrunk, or file expanded, just to make it obvious to the user
395 (without having to the refer to file size), just how the file size
398 Would this option be for all file, or just one file? Or a fileset?
399 - Make output from status use html table tags for nicely
400 presenting in a browser.
401 - Can one write tapes faster with 8192 byte block sizes?
402 - Document security problems with the same password for everyone in
403 rpm and Win32 releases.
404 - Browse generations of files.
405 - I've seen an error when my catalog's File table fills up. I
406 then have to recreate the File table with a larger maximum row
407 size. Relevant information is at
408 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
409 "Installing and Configuring MySQL" chapter should talk a bit
410 about this potential problem, and recommend a solution.
411 - For Solaris must use POSIX awk.
412 - Want speed of writing to tape while despooling.
413 - Supported autochanger:
421 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
422 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
423 - Add regex from http://www.pcre.org to Bacula for Win32.
424 - Use only shell tools no make in CDROM package.
425 - Include within include does it work?
426 - Implement a Pool of type Cleaning?
427 - Implement VolReadTime and VolWriteTime in SD
428 - Modify Backing up Your Database to include a bootstrap file.
429 - Think about making certain database errors fatal.
430 - Look at correcting the time jump in the scheduler for daylight
431 savings time changes.
432 - Add a "real" timer to network connections.
433 - Promote to Full = Time period
434 - Check dates entered by user for correctness (month/day/... ranges)
435 - Compress restore Volume listing by date and first file.
436 - Look at patches/bacula_db.b2z postgresql that loops during restore.
438 - Perhaps add read/write programs and/or plugins to FileSets.
439 - How to handle backing up portables ...
440 - Add some sort of guaranteed Interval for upgrading jobs.
441 - Can we write the state file after every job terminates? On Win32
442 the system crashes and the state file is not updated.
445 Documentation to do: (any release a little bit at a time)
446 - Doc to do unmount before removing magazine.
447 - Alternative to static linking "ldd prog" save all binaries listed,
448 restore them and point LD_LIBRARY_PATH to them.
449 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
450 - Document query file format.
451 - Add more documentation for bsr files.
452 - Document problems with Verify and pruning.
453 - Document how to use multiple databases.
454 - VXA drives have a "cleaning required"
455 indicator, but Exabyte recommends preventive cleaning after every 75
458 In this context, it should be noted that Exabyte has a command-line
459 vxatool utility available for free download. (The current version is
460 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
461 test the drive, unload tapes, change drive settings, flash new firmware,
463 Of particular interest in this context is that vxatool <device> -i will
464 report, among other details, the time since last cleaning in tape motion
465 minutes. This information can be retrieved (and settings changed, for
466 that matter) through the generic-SCSI device even when Bacula has the
467 regular tape device locked. (Needless to say, I don't recommend
468 changing tape settings while a job is running.)
469 - Lookup HP cleaning recommendations.
470 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
471 - Document doing table repair
474 ===================================
475 - Add macro expansions in JobDefs.
476 Run Before Job = "SomeFile %{Level} %{Client}"
477 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
478 - Use non-blocking network I/O but if no data is available, use
480 - Use gather write() for network I/O.
481 - Autorestart on crash.
482 - Add bandwidth limiting.
483 - Add acks every once and a while from the SD to keep
484 the line from timing out.
485 - When an error in input occurs and conio beeps, you can back
486 up through the prompt.
487 - Detect fixed tape block mode during positioning by looking at
488 block numbers in btape "test". Possibly adjust in Bacula.
489 - Fix list volumes to output volume retention in some other
490 units, perhaps via a directive.
491 - If opening a tape in read/write mode fails attempt to open
492 it in read-only mode, and mark the tape for read only.
493 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
494 with multiple priorities.
495 - If you use restore replace=never, the directory attributes for
496 non-existent directories will not be restored properly.
498 - see lzma401.zip in others directory for new compression
500 - Minimal autochanger handling in Bacula and in btape.
501 - Look into how tar does not save sockets and the possiblity of
502 not saving them in Bacula (Martin Simmons reported this).
503 - Fix restore jobs so that multiple jobs can run if they
504 are not using the same tape(s).
505 - Allow the user to select JobType for manual pruning/purging.
506 - bscan does not put first of two volumes back with all info in
508 - Implement the FreeBSD nodump flag in chflags.
509 - Figure out how to make named console messages go only to that
510 console and to the non-restricted console (new console class?).
511 - Make restricted console prompt for password if *ask* is set or
512 perhaps if password is undefined.
513 - Implement "from ISO-date/time every x hours/days/weeks/months" in
516 ==== from Marc Schoechlin
517 - the help-command should be more verbose
518 (it should explain the paramters of the different
520 -> its time-comsuming to consult the manual anytime
521 you need a special parameter
522 -> maybe its more easy to maintain this, if the
523 descriptions of that commands are outsourced to
525 - the cd-command should allow complete paths
526 i.e. cd /foo/bar/foo/bar
527 -> if a customer mails me the path to a certain file,
528 its faster to enter the specified directory
529 - if the password is not configured in bconsole.conf
530 you should be asked for it.
531 -> sometimes you like to do restore on a customer-machine
532 which shouldnt know the password for bacula.
533 -> adding the password to the file favours admins
534 to forget to remove the password after usage
536 the protection of that file is less important
537 - long-listed-output of commands should be scrollable
538 like the unix more/less-command does
539 -> if someone runs 200 and more machines, the lists could
540 be a little long and complex
541 - command-output should be shown column by column
542 to reduce scrolling and to increase clarity
544 - lsmark should list the selected files with full
546 - wildcards for selecting and file and directories would be nice
547 - any actions should be interuptable with STRG+C
548 - command-expansion would be pretty cool
550 - When the replace Never option is set, new directory permissions
551 are not restored. See bug 213. To fix this requires creating a
552 list of newly restored directories so that those directory
553 permissions *can* be restored.
554 - Compaction of Disk space by "migrating" Volumes that have pruned
555 Jobs (what criteria? size, #jobs, time).
556 - Add prune all command
557 - Document fact that purge can destroy a part of a restore by purging
558 one volume while others remain valid -- perhaps mark Jobs.
559 - Add multiple-media-types.txt
560 - look at mxt-changer.html
561 - Make ? do a help command (no return needed).
562 - Implement restore directory.
563 - Document streams and how to implement them.
564 - Try not to re-backup a file if a new hard link is added.
565 - Add feature to backup hard links only, but not the data.
566 - Fix stream handling to be simpler.
567 - Add Priority and Bootstrap to Run a Job.
568 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
570 - Remove View FileSet button from Run a Job dialog.
571 - Handle prompt for restore job at end of Restore command.
572 - Add display of total selected files to Restore window.
573 - Add tree pane to left of window.
574 - Add progress meter.
575 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
576 - Document writing to a CD/DVD with Bacula.
577 - Add a "base" package to the window installer for pthreadsVCE.dll
578 which is needed by all packages.
579 - Add message to user to check for fixed block size when the forward
580 space test fails in btape.
581 - When unmarking a directory check if all files below are unmarked and
582 then remove the + flag -- in the restore tree.
583 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
584 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
585 - Revisit the question of multiple Volumes (disk) on a single device.
586 - Add a block copy option to bcopy.
587 - Investigate adding Mac Resource Forks.
588 - Finish work on Gnome restore GUI.
589 - Fix "llist jobid=xx" where no fileset or client exists.
590 - For each job type (Admin, Restore, ...) require only the really necessary
591 fields.- Pass Director resource name as an option to the Console.
592 - Add a "batch" mode to the Console (no unsolicited queries, ...).
593 - Add a .list all files in the restore tree (probably also a list all files)
594 Do both a long and short form.
595 - Allow browsing the catalog to see all versions of a file (with
596 stat data on each file).
597 - Restore attributes of directory if replace=never set but directory
599 - Use SHA1 on authentication if possible.
600 - See comtest-xxx.zip for Windows code to talk to USB.
601 - Add John's appended files:
602 Appended = { /files/server/logs/http/*log }
603 and such files would be treated as follows.On a FULL backup, they would
604 be backed up like any other file.On an INCREMENTAL backup, where a
605 previous INCREMENTAL or FULL was already in thecatalogue and the length
606 of the file wasgreater than the length of the last backup, only thedata
607 added since the last backup will be dumped.On an INCREMENTAL backup, if
608 the length of the file is less than thelength of the file with the same
609 name last backed up, the completefile is dumped.On Windows systems, with
610 creation date of files, we can be evensmarter about this and not count
611 entirely upon the length.On a restore, the full and all incrementals
612 since it will beapplied in sequence to restore the file.
613 - Check new HAVE_WIN32 open bits.
614 - Check if the tape has moved before writing.
615 - Handling removable disks -- see below:
616 - Keep track of tape use time, and report when cleaning is necessary.
617 - Add FromClient and ToClient keywords on restore command (or
618 BackupClient RestoreClient).
619 - Implement a JobSet, which groups any number of jobs. If the
620 JobSet is started, all the jobs are started together.
621 Allow Pool, Level, and Schedule overrides.
622 - Enhance cancel to timeout BSOCK packets after a specific delay.
623 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
624 ua_status.!!! Thanks to Alan Brown for this tip.
625 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
626 correctly for multiple simultaneous jobs.
627 - Correct code so that FileSet MD5 is calculated for < and | filename
629 - Implement the Media record flag that indicates that the Volume does disk
631 - Implement VolAddr, which is used when Volume is addressed like a disk,
632 and form it from VolFile and VolBlock.
633 - Make multiple restore jobs for multiple media types specifying
634 the proper storage type.
635 - Fix fast block rejection (stored/read_record.c:118). It passes a null
636 pointer (rec) to try_repositioning().
637 - Look at extracting Win data from BackupRead.
638 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
639 which would take precidence over the Catalog "JobRetention".
640 - Implement Label Format in Add and Label console commands.
641 - Possibly up network buffers to 65K. Put on variable.
642 - Put email tape request delays on one or more variables. User wants
643 to cancel the job after a certain time interval. Maximum Mount Wait?
644 - Job, Client, Device, Pool, or Volume?
645 Is it possible to make this a directive which is *optional* in multiple
646 resources, like Level? If so, I think I'd make it an optional directive
647 in Job, Client, and Pool, with precedence such that Job overrides Client
648 which in turn overrides Pool.
650 - New Storage specifications:
651 - Want to write to multiple storage devices simultaneously
652 - Want to write to multiple storage devices sequentially (in one job)
653 - Want to read/write simultaneously
654 - Key is MediaType -- it must match
656 Passed to SD as a sort of BSR record called Storage Specification
660 MediaType -> Next MediaType
662 Device -> Next Device
664 Allow multiple Storage specifications
672 Allow Multiple Pool specifications (note, Pool currently
674 Allow Multiple MediaType specifications in Dir conf
675 Allow Multiple Device specifications in Dir conf
676 Perhaps keep this in a single SSR
677 Tie a Volume to a specific device by using a MediaType that
678 is contained in only one device.
679 In SD allow Device to have Multiple MediaTypes
681 - Ideas from Jerry Scharf:
682 First let's point out some big pluses that bacula has for this
684 more importantly it's active. Thank you so much for that
685 even more important, it's not flaky
686 it has an open access catalog, opening many possibilities
687 it's pushing toward heterogeneous systems capability
689 Macintosh file client
690 macs are an interesting niche, but I fear a server is a rathole
691 working bare iron recovery for windows
692 the option for inc/diff backups not reset on fileset revision
693 a) use both change and inode update time against base time
694 b) do the full catalog check (expensive but accurate)
695 sizing guide (how much system is needed to back up N systems/files)
696 consultants on using bacula in building a disaster recovery system
698 or how to get at fancy things that one could do with bacula
699 logwatch code for bacula logs (or similar)
700 linux distro inclusion of bacula (brings good and bad, but necessary)
701 win2k/XP server capability (icky but you asked)
702 support for Oracle database ??
704 - Look at adding SQL server and Exchange support for Windows.
705 - Make dev->file and dev->block_num signed integers so that -1 can
706 be an invalid value which happens with BSR.
707 - Create VolAddr for disk files in place of VolFile and VolBlock. This
708 is needed to properly specify ranges.
709 - Add progress of files/bytes to SD and FD.
710 - Print warning message if FileId > 4 billion
711 - do a "messages" before the first prompt in Console
712 - Client does not show busy during Estimate command.
713 - Implement Console mtx commands.
714 - Implement a Mount Command and an Unmount Command where
715 the users could specify a system command to be performed
716 to do the mount, after which Bacula could attempt to
717 read the device. This is for Removeable media such as a CDROM.
718 - Most likely, this mount command would be invoked explicitly
719 by the user using the current Console "mount" and "unmount"
720 commands -- the Storage Daemon would do the right thing
721 depending on the exact nature of the device.
722 - As with tape drives, when Bacula wanted a new removable
723 disk mounted, it would unmount the old one, and send a message
724 to the user, who would then use "mount" as described above
725 once he had actually inserted the disk.
726 - Implement dump/print label to UA
727 - Spool to disk only when the tape is full, then when a tape is hung move
729 - bextract is sending everything to the log file ****FIXME****
730 - Allow multiple Storage specifications (or multiple names on
731 a single Storage specification) in the Job record. Thus a job
732 can be backed up to a number of storage devices.
733 - Implement some way for the File daemon to contact the Director
734 to start a job or pass its DHCP obtained IP number.
735 - Implement a query tape prompt/replace feature for a console
736 - Copy console @ code to gnome2-console
737 - Make AES the only encryption algorithm see
738 http://csrc.nist.gov/CryptoToolkit/aes/). It's
739 an officially adopted standard, has survived peer
740 review, and provides keys up to 256 bits.
741 - Take a careful look at SetACL http://setacl.sourceforge.net
742 - Make tree walk routines like cd, ls, ... more user friendly
743 by handling spaces better.
744 - Make sure that Bacula rechecks the tape after the 20 min wait.
745 - Set IO_NOWAIT on Bacula TCP/IP packets.
746 - Try doing a raw partition backup and restore by mounting a
749 Yes, it would allow to highly automatic the request for new tapes. If a
750 tape is empty, bacula reads the barcodes (native or simulated), and if
751 an unused tape is found, it runs the label command with all the
752 necessary parameters.
754 By the way can bacula automatically "move" an empty/purged volume say
755 in the "short" pool to the "long" pool if this pool runs out of volume
757 - What to do about "list files job=xxx".
758 - Get and test MySQL 4.0
759 - Look at how fuser works and /proc/PID/fd that is how Nic found the
760 file descriptor leak in Bacula.
761 - Implement WrapCounters in Counters.
762 - Add heartbeat from FD to SD if hb interval expires.
763 - Can we dynamically change FileSets?
764 - If pool specified to label command and Label Format is specified,
765 automatically generate the Volume name.
766 - Why can't SQL do the filename sort for restore?
767 - Add ExhautiveRestoreSearch
768 - Look at the possibility of loading only the necessary
769 data into the restore tree (i.e. do it one directory at a
770 time as the user walks through the tree).
771 - Possibly use the hash code if the user selects all for a restore command.
772 - Fix "restore all" to bypass building the tree.
773 - Prohibit backing up archive device (findlib/find_one.c:128)
774 - Implement Release Device in the Job resource to unmount a drive.
775 - Implement Acquire Device in the Job resource to mount a drive,
776 be sure this works with admin jobs so that the user can get
777 prompted to insert the correct tape. Possibly some way to say to
778 run the job but don't save the files.
779 - Make things like list where a file is saved case independent for
782 - Use autochanger to handle multiple devices.
783 - On Windows with very long path names, it may be impossible to create
784 a file (and thus restore it) because the total length is too long.
785 We must cd into the directory then create the file without the
787 - Implement a Recycle command
788 - Test a second language e.g. french.
789 - Start working on Base jobs.
790 - Implement UnsavedFiles DB record.
791 - From Phil Stracchino:
792 It would probably be a per-client option, and would be called
793 something like, say, "Automatically purge obsoleted jobs". What it
794 would do is, when you successfully complete a Differential backup of a
795 client, it would automatically purge all Incremental backups for that
796 client that are rendered redundant by that Differential. Likewise,
797 when a Full backup on a client completed, it would automatically purge
798 all Differential and Incremental jobs obsoleted by that Full backup.
799 This would let people minimize the number of tapes they're keeping on
800 hand without having to master the art of retention times.
801 - When doing a Backup send all attributes back to the Director, who
802 would then figure out what files have been deleted.
803 - Currently in mount.c:236 the SD simply creates a Volume. It should have
804 explicit permission to do so. It should also mark the tape in error
805 if there is an error.
806 - Cancel waiting for Client connect in SD if FD goes away.
808 - Implement timeout in response() when it should come quickly.
809 - Implement a Slot priority (loaded/not loaded).
810 - Implement "vacation" Incremental only saves.
811 - Implement create "FileSet"?
812 - Add prefixlinks to where or not where absolute links to FD.
813 - Issue message to mount a new tape before the rewind.
814 - Simplified client job initiation for portables.
815 - If SD cannot open a drive, make it periodically retry.
816 - Add more of the config info to the tape label.
818 - If tape is marked read-only, then try opening it read-only rather than
819 failing, and remember that it cannot be written.
820 - Refine SD waiting output:
821 Device is being positioned
822 > Device is being positioned for append
823 > Device is being positioned to file x
825 - Figure out some way to estimate output size and to avoid splitting
826 a backup across two Volumes -- this could be useful for writing CDROMs
827 where you really prefer not to have it split -- not serious.
828 - Have SD compute MD5 or SHA1 and compare to what FD computes.
829 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
830 actual data on the Volume and compare it.
831 - Implement Bacula plugins -- design API
832 - Make bcopy read through bad tape records.
833 - Program files (i.e. execute a program to read/write files).
834 Pass read date of last backup, size of file last time.
835 - Add Signature type to File DB record.
836 - CD into subdirectory when open()ing files for backup to
837 speed up things. Test with testfind().
838 - Priority job to go to top of list.
839 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
840 - Implement some way for the Console to dynamically create a job.
841 - Solaris -I on tar for include list
842 - Need a verbose mode in restore, perhaps to bsr.
843 - bscan without -v is too quiet -- perhaps show jobs.
844 - Add code to reject whole blocks if not wanted on restore.
845 - Check if we can increase Bacula FD priorty in Win2000
846 - Make sure the MaxVolFiles is fully implemented in SD
847 - Check if both CatalogFiles and UseCatalog are set to SD.
848 - Possibly add email to Watchdog if drive is unmounted too
849 long and a job is waiting on the drive.
850 - After unmount, if restore job started, ask to mount.
851 - Add UA rc and history files.
852 - put termcap (used by console) in ./configure and
853 allow -with-termcap-dir.
854 - Fix Autoprune for Volumes to respect need for full save.
855 - Compare tape to Client files (attributes, or attributes and data)
856 - Make all database Ids 64 bit.
857 - Allow console commands to detach or run in background.
858 - Fix status delay on storage daemon during rewind.
859 - Add SD message variables to control operator wait time
860 - Maximum Operator Wait
861 - Minimum Message Interval
862 - Maximum Message Interval
863 - Send Operator message when cannot read tape label.
864 - Verify level=Volume (scan only), level=Data (compare of data to file).
865 Verify level=Catalog, level=InitCatalog
867 - Add keyword search to show command in Console.
868 - Events : tape has more than xxx bytes.
869 - Complete code in Bacula Resources -- this will permit
870 reading a new config file at any time.
871 - Handle ctl-c in Console
872 - Implement script driven addition of File daemon to config files.
873 - Think about how to make Bacula work better with File (non-tape) archives.
874 - Write Unix emulator for Windows.
875 - Put memory utilization in Status output of each daemon
876 if full status requested or if some level of debug on.
877 - Make database type selectable by .conf files i.e. at runtime
878 - Set flag for uname -a. Add to Volume label.
879 - Restore files modified after date
880 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
881 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
882 - Timout a job or terminate if link goes down, or reopen link and query.
883 - Concept of precious tapes (cannot be reused).
884 - Make bcopy copy with a single tape drive.
885 - Permit changing ownership during restore.

899 - Autolabel should be specified by DIR instead of SD.
902 - AutoScan (check checksum of tape)
903 - Format command = "format /dev/nst0"
907 - Seek resolution (usually corresponds to buffer size)
908 - EODErrorCode=ENOSPC or code
909 - Partial Read error code
910 - Partial write error code
911 - Nonformatted read error
912 - Nonformatted write error
913 - WriteProtected error
917 - IgnoreCloseErrors=yes
927 - FD sends unsaved file list to Director at end of job (see
929 - File daemon should build list of files skipped, and then
930 at end of save retry and report any errors.
931 - Write a Storage daemon that uses pipes and
932 standard Unix programs to write to the tape.
934 - Need something that monitors the JCR queue and
935 times out jobs by asking the deamons where they are.
936 - Enhance Jmsg code to permit buffering and saving to disk.
937 - device driver = "xxxx" for drives.
939 - Ensure that /dev/null works
940 - Need report class for messages. Perhaps
941 report resource where report=group of messages
942 - enhance scan_attrib and rename scan_jobtype, and
943 fill in code for "since" option
944 - Director needs a time after which the report status is sent
945 anyway -- or better yet, a retry time for the job.
946 - Don't reschedule a job if previous incarnation is still running.
947 - Some way to automatically backup everything is needed????
948 - Need a structure for pending actions:
950 - termination status (part of buffered msgs?)
952 Read, Write, Clean, Delete
953 - Login to Bacula; Bacula users with different permissions:
954 owner, group, user, quotas
955 - Store info on each file system type (probably in the job header on tape.
956 This could be the output of df; or perhaps some sort of /etc/mtab record.
958 ========= ideas ===============
959 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
960 To: <kern@sibbald.com>
961 Subject: RE: [Bacula-users] future large programming jobs
962 Date: Thu, 26 Feb 2004 11:34:54 -0600
964 I noticed the subject thread and thought I would offer the following
965 merely as sources of ideas, i.e. something to think about, not even as
966 strong as a request. In my former life (before retiring) I often
967 dealt with backups and storage management issues/products as a
968 developer and as a consultant. I am currently migrating my personal
969 network from amanda to bacula specifically because of the ability to
970 cross media boundaries during storing backups.
971 Are you familiar with the commercial product called ADSM (I think IBM
972 now sells it under the Tivoli label)? It has a couple of interesting
973 ideas that may apply to the following topics.
975 1. Migration: Consider that when you need to restore a system, there
976 may be pressure to hurry. If all the information for a single client
977 can eventually end up on the same media (and in chronological order),
978 the restore is facillitated by not having to search past information
979 from other clients. ADSM has the concept of "client affinity" that
980 may be associated with it's storage pools. It seems to me that this
981 concept (as an optional feature) might fit in your architecture for
984 ADSM also has the concept of defining one or more storage pools as
985 "copy pools" (almost mirrors, but only in the sense of contents).
986 These pools provide the ability to have duplicte data stored both
987 onsite and offsite. The copy process can be scheduled to be handled
988 by their storage manager during periods when there is no backup
989 activity. Again, the migration process might be a place to consider
990 implementing something like this.
993 > It strikes me that it would be very nice to be able to do things
995 > have the Job(s) backing up the machines run, and once they have all

1001 > mechanism described below would probably make it very easy.
1003 This is the goal. In the first step (before events), you simply
1005 the Migration to tape later.
1007 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1008 the database. Once a file (unique by path and metadata such as dates,
1009 size, ownership, etc.) is in a copy pool, no more copies are made. In
1010 other words, when you start ADSM, it begins like your concept of a
1011 base job. After that it is in the "incremental" mode. You can
1012 configure the number of "generations" of files to be retained, plus a
1013 retention date after which even old generations are purged. The
1014 database tracks the contents of media and projects the percentage of
1015 each volume that is valid. When the valid content of a volume drops
1016 below a configured percentage, the valid data are migrated to another
1017 volume and the old volume is marked as empty. Note, this requires
1018 ADSM to have an idea of the contents of a client, i.e. marking the
1019 database when an existing file was deleted, but this would solve your
1020 issue of restoring a client without restoring deleted files.
1022 This is pretty far from what bacula now does, but if you are going to
1023 rip things up for Base jobs,.....
1024 Also, the benefits of this are huge for very large shops, especially
1025 with media robots, but are a pain for shops with manual media
1029 > Base jobs sound pretty useful, but I'm not dying for them.
1031 Nobody is dying for them, but when you see what it does, you will die
1034 3. Restoring deleted files: Since I think my comments in (2) above
1035 have low probability of implementation, I'll also suggest that you
1036 could approach the issue of deleted files by a mechanism of having the
1037 fd report to the dir, a list of all files on the client for every
1038 backup job. The dir could note in the database entry for each file
1039 the date that the file was seen. Then if a restore as of date X takes
1040 place, only files that exist from before X until after X would be
1041 restored. Probably the major cost here is the extra date container in
1042 each row of the files table.
1044 Thanks for "listening". I hope some of this helps. If you want to
1045 contact me, please send me an email - I read some but not all of the
1046 mailing list traffic and might miss a reply there.
1048 Please accept my compliments for bacula. It is doing a great job for
1049 me!! I sympathize with you in the need to wrestle with excelence in
1050 execution vs. excelence in feature inclusion.
1055 ==============================
1058 - Design at hierarchial storage for Bacula. Migration and Clone.
1059 - Implement FSM (File System Modules).
1060 - Audit M_ error codes to ensure they are correct and consistent.
1061 - Add variable break characters to lex analyzer.
1062 Either a bit mask or a string of chars so that
1063 the caller can change the break characters.
1064 - Make a single T_BREAK to replace T_COMMA, etc.
1065 - Ensure that File daemon and Storage daemon can
1066 continue a save if the Director goes down (this
1067 is NOT currently the case). Must detect socket error,
1068 buffer messages for later.
1069 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1070 - Add ability to backup to two Storage devices (two SD sessions) at
1071 the same time -- e.g. onsite, offsite.
1072 - Add the ability to consolidate old backup sets (basically do a restore
1073 to tape and appropriately update the catalog). Compress Volume sets.
1074 Might need to spool via file is only one drive is available.
1075 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1076 someway to do so with every volume that has less than x% valid
1080 Migration: Move a backup from one Volume to another
1081 Clone: Copy a backup -- two Volumes
1083 Bacula Migration is based on Jobs (apparently Networker is file by file).
1085 Migration triggered by:
1089 Highwater mark (keep total size)
1094 ======================================================
1096 It is somewhat like a Full save becomes an incremental since
1097 the Base job (or jobs) plus other non-base files.
1099 - A Base backup is same as Full backup, just different type.
1100 - New BaseFiles table that contains:
1102 BaseJobId - Base JobId referenced for this FileId (needed ???)
1103 JobId - JobId currently running
1104 FileId - File not backed up, exists in Base Job
1105 FileIndex - FileIndex from Base Job.
1106 i.e. for each base file that exists but is not saved because
1107 it has not changed, the File daemon sends the JobId, BaseId,
1108 FileId, FileIndex back to the Director who creates the DB entry.
1109 - To initiate a Base save, the Director sends the FD
1110 the FileId, and full filename for each file in the Base.
1111 - When the FD finds a Base file, he requests the Director to
1112 send him the full File entry (stat packet plus MD5), or
1113 conversely, the FD sends it to the Director and the Director
1114 says yes or no. This can be quite rapid if the FileId is kept
1115 by the FD for each Base Filename.
1116 - It is probably better to have the comparison done by the FD
1117 despite the fact that the File entry must be sent across the
1119 - An alternative would be to send the FD the whole File entry
1120 from the start. The disadvantage is that it requires a lot of
1121 space. The advantage is that it requires less communications
1123 - The Job record must be updated to indicate that one or more
1125 - At end of Job, FD returns:
1126 1. Count of base files/bytes not written to tape (i.e. matches)
1127 2. Count of base file that were saved i.e. had changed.
1128 - No tape record would be written for a Base file that matches, in the
1129 same way that no tape record is written for Incremental jobs where
1130 the file is not saved because it is unchanged.
1131 - On a restore, all the Base file records must explicitly be
1132 found from the BaseFile tape. I.e. for each Full save that is marked
1133 to have one or more Base Jobs, search the BaseFile for all occurrences
1135 - An optimization might be to make the BaseFile have:
1141 This would avoid the need to explicitly fetch each File record for
1142 the Base job. The Base Job record will be fetched to get the
1143 VolSessionId and VolSessionTime.
1144 =========================================================
1147 ==========================================================
1149 For each Incremental job that is run, there may be files that
1150 were found but not saved because they were locked (this applies
1151 only to Windows). Such a system could send back to the Director
1152 a list of Unsaved files.
1154 - New UnSavedFiles table that contains:
1158 - Then in the next Incremental job, the list of Unsaved Files will be
1159 feed to the FD, who will ensure that they are explicitly chosen even
1160 if standard date/time check would not have selected them.

1205 There needs to be a table of drive # to devices somewhere - If there are
1206 multiple changers or drives there may not be a 1:1 correspondance between
1207 changer drive number and system device name - and depending on the way the
1208 drives are hooked up to scsi busses, they may not be linearly numbered
1209 from an offset point either.something like
1211 Autochanger drives = 2
1212 Autochanger drive 0 = /dev/nst1
1213 Autochanger drive 1 = /dev/nst2
1214 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1215 times, not just for multidrive changers. For a 1 drive changer, that's
1221 MTX's manpage (1.2.15):
1222 unload [<slotnum>] [ <drivenum> ]
1223 Unloads media from drive <drivenum> into slot
1224 <slotnum>. If <drivenum> is omitted, defaults to
1225 drive 0 (as do all commands). If <slotnum> is
1226 omitted, defaults to the slot that the drive was
1227 loaded from. Note that there's currently no way
1228 to say 'unload drive 1's media to the slot it
1229 came from', other than to explicitly use that
1230 slot number as the destination.AB

1268 Handling removable disks
1270 From: Karl Cunningham <karlc@keckec.com>
1272 My backups are only to hard disk these days, in removable bays. This is my
1273 idea of how a backup to hard disk would work more smoothly. Some of these
1274 things Bacula does already, but I mention them for completeness. If others
1275 have better ways to do this, I'd like to hear about it.
1277 1. Accommodate several disks, rotated similar to how tapes are. Identified
1278 by partition volume ID or perhaps by the name of a subdirectory.
1279 2. Abort & notify the admin if the wrong disk is in the bay.
1280 3. Write backups to different subdirectories for each machine to be backed
1282 4. Volumes (files) get created as needed in the proper subdirectory, one
1284 5. When a disk is recycled, remove or zero all old backup files. This is
1285 important as the disk being recycled may be close to full. This may be
1286 better done manually since the backup files for many machines may be
1287 scattered in many subdirectories.
1292 - Save mount point for directories not traversed with onefs=yes.
1293 - Add seconds to start and end times in the Job report output.
1294 - if 2 concurrent backups are attempted on the same tape
1295 drive (autoloader) into different tape pools, one of them will exit
1296 fatally instead of halting until the drive is idle
1297 - Update StartTime if job held in Job Queue.
1298 - Look at www.nu2.nu/pebuilder as a helper for full windows
1299 bare metal restore. (done by Scott)
1300 - Fix orphanned buffers:
1301 Orphaned buffer: 24 bytes allocated at line 808 of rufus-dir job.c
1302 Orphaned buffer: 40 bytes allocated at line 45 of rufus-dir alist.c
1303 - Implement Preben's suggestion to add
1304 File System Types = ext2, ext3
1305 to FileSets, thus simplifying backup of *all* local partitions.
1306 - Try to open a device on each Job if it was not opened
1307 when the SD started.
1308 - Add dump of VolSessionId/Time and FileIndex with bls.
1309 - If Bacula does not find the right tape in the Autochanger,
1310 then mark the tape in error and move on rather than asking
1311 for operator intervention.
1312 - Cancel command should include JobId in list of Jobs.
1313 - Add performance testing hooks
1314 - Bootstrap from JobMedia records.
1315 - Implement WildFile and WildDir to solve problem of
1316 saving only *.doc files.
1318 Please use the "label" command to create a new Volume for:
1319 Storage: DDS-4-changer
1323 The defined Storage resources are:
1324 - Copy Changer Device and Changer Command from Autochanger
1325 to Device resource in SD if none given in Device resource.
1326 - 1. Automatic use of more than one drive in an autochanger (done)
1327 - 2. Automatic selection of the correct drive for each Job (i.e.
1328 selects a drive with an appropriate Volume for the Job) (done)
1329 - 6. Allow multiple simultaneous Jobs referencing the same pool write
1330 to several tapes (some new directive(s) are are probably needed for
1333 - Key on Storage rather than Pool (done)
1334 - Allow multiple drives to use same Pool (change jobq.c DIR) (done).
1335 - Synchronize multiple drives so that not more
1336 than one loads a tape and any time (done)
1337 - 4. Use Changer Device and Changer Command specified in the
1338 Autochanger resource, if none is found in the Device resource.
1339 You can continue to specify them in the Device resource if you want
1340 or need them to be different for each device.
1341 - 5. Implement a new Device directive (perhaps "Autoselect = yes/no")
1342 that can allow a Device be part of an Autochanger, and hence the changer
1343 script protected, but if set to no, will prevent the Device from being
1344 automatically selected from the changer. This allows the device to
1345 be directly accessed through its Device name, but not through the
1347 #6 Select one from among Multiple Storage Devices for Job
1348 #5 Events that call a Python program
1349 (Implemented in Dir/SD)
1350 - Make sure the Device name is in the Query packet returned.
1351 - Don't start a second file job if one is already running.
1352 - Implement EOF/EOV labels for ANSI labels
1353 - Implement IBM labels.
1354 - When Python creates a new label, the tape is immediately
1355 recycled and no label created. This happens when using
1356 autolabeling -- even when Python doesn't generate the name.
1357 - Scratch Pool where the volumes can be re-assigned to any Pool.
1358 - 28-Mar 23:19 rufus-sd: acquire.c:379 Device "DDS-4" (/dev/nst0)
1359 is busy reading. Job 6 canceled.
1360 - Remove separate thread for opening devices in SD. On the other
1361 hand, don't block waiting for open() for devices.
1362 - Fix code to either handle updating NumVol or to calculate it in
1364 - Ensure that you cannot exclude a directory or a file explicitly
1366 #4 Embedded Python Scripting
1367 (Implemented in Dir/SD/FD)
1368 - Add Python writable variable for changing the Priority,
1369 Client, Storage, JobStatus (error), ...
1372 - Add disk seeking on restore; turn off seek on tapes.
1374 - Look at dird_conf.c:1000: warning: `int size'
1375 might be used uninitialized in this function
1376 - Indicate when a Job is purged/pruned during restore.
1377 - Implement some way to turn off automatic pruning in Jobs.
1378 - Implement a way an Admin Job can prune, possibly multiple
1379 clients -- Python script?
1380 - Look at Preben's acl.c error handling code.
1381 - SD crashes after a tape restore then doing a backup.
1382 - If drive is opened read/write, close it and re-open
1383 read-only if doing a restore, and vice-versa.
1385 data-fd: RestoreFiles.2004-12-07_15.56.42 Error:
1386 > ..\findlib\../../findlib/create_file.c:275 Could not open e:/: ERR=Der

1389 Restore restores all files, but then fails at the end trying
1390 to set the attributes of e:
1391 from failed jobs.- Resolve the problem between Device name and Archive name,
1392 and fix SD messages.
1393 - Tell the "restore" user when browsing is no longer possible.
1394 - Add a restore directory-x
1395 - Write non-optimized bsrs from the JobMedia and Media records,
1396 even after Files are pruned.
1397 - Delete Stripe and Copy from VolParams to save space.
1398 - Fix option 2 of restore -- list where file is backed up -- require Client,
1399 then list last 20 backups.
1400 - Finish implementation of passing all Storage and Device needs to
1402 - Move test for max wait time exceeded in job.c up -- Peter's idea.
1403 ## Consider moving docs to their own project.
1404 ## Move rescue to its own project.
1405 - Add client version to the Client name line that prints in
1407 - Fix the Rescue CDROM.
1408 - By the way: on page http://www.bacula.org/?page=tapedrives , at the
1409 bottom, the link to "Tape Testing Chapter" is broken. It goes to
1410 /html-manual/... while the others point to /rel-manual/...
1411 - Device resource needs the "name" of the SD.
1412 - Specify a single directory to restore.
1413 - Implement MediaType keyword in bsr?
1414 - Add a date and time stamp at the beginning of every line in the
1415 Job report (Volker Sauer).
1416 - Add level to estimate command.
1417 - Add "limit=n" for "list jobs"
1418 - Make bootstrap filename unique.
1419 - Make Dmsg look at global before calling subroutine.
1421 it seems to be complaining about 12:00pm which should be a valid 12
1422 hour time. I changed the time to 11:59am and everything works fine.
1423 Also 12:00am works fine. 0:00pm also works (which I don't think
1424 should). None of the values 12:00pm - 12:59pm work for that matter.
1425 - Require restore via the restore command or make a restore Job
1426 get the bootstrap file.
1427 - Implement Maximum Job Spool Size
1428 - Fix 3993 error in SD. It forgets to look at autochanger
1429 resource for device command, ...
1430 - 3. Prevent two drives requesting the same Volume in any given
1431 autochanger, by checking if a Volume is mounted on another drive
1433 - Upgrade to MySQL 4.1.12 See:
1434 http://dev.mysql.com/doc/mysql/en/Server_SQL_mode.html
1435 - Add # Job Level date to bsr file
1436 - Implement "PreferMountedVolumes = yes|no" in Job resource.
1437 ## Integrate web-bacula into a new Bacula project with
1439 - Cleaning tapes should have Status "Cleaning" rather than append.
1440 - Make sure that Python has access to Client address/port so that
1441 it can check if Clients are alive.
1442 - Review all items in "restore".
1443 - Fix PostgreSQL GROUP BY problems in restore.
1444 - Fix PostgreSQL sql problems in bugs.

1452 ## Create a new GUI chapter explaining all the GUI programs.
1453 - Make "update slots" when pointing to Autochanger, remove
1454 all Volumes from other drives. "update slots all-drives"?
1455 No, this is done by modifying mtx-changer to list what is
1457 - Finish TLS implementation.
1458 - Port limiting -m in iptables to prevent DoS attacks
1459 could cause broken pipes on Bacula.
1460 6. Build and test the Volume Shadow Copy (VSS) for Win32.
1461 - Allow cancel of unknown Job
1462 - State not saved when closing Win32 FD by icon
1463 - bsr-opt-test fails. bsr deleted. Fix.
1464 - Move Python daemon variables from Job to Bacula object.
1465 WorkingDir, ConfigFile
1466 - Document that Bootstrap files can be written with cataloging
1468 - Document details of ANSI/IBM labels
