20 ## Integrate web-bacula into a new Bacula project with
22 ## Consider moving docs to their own project.
24 Suggestions for Preben:
25 - Look at adding Client run command that will use the
26 port opened by the client.
27 - Implement WildFile and WildDir to solve problem of
28 saving only *.doc files.
29 - Bootstrap from JobMedia records.
30 - Optimized bootstrap.
34 data-fd: RestoreFiles.2004-12-07_15.56.42 Error:
35 > ..\findlib\../../findlib/create_file.c:275 Could not open e:/: ERR=Der
36 > Prozess kann nicht auf die Datei zugreifen, da sie von einem anderen
37 > Prozess verwendet wird.
38 Restore restores all files, but then fails at the end.
39 - Add better documentation on how restores can be done
41 - Resolve the problem between Device name and Archive name,
43 - Make sure SD deletes spool files on error exit.
44 - Delete old spool files when SD starts.
45 - When Python creates a new label, the tape is immediately
46 recycled and no label created. This happens when using
47 autolabeling -- even when Python doesn't generate the name.
48 - Add a restore directory-x
49 - When labeling tapes, if you enter 000026, Bacula uses
50 the tape index rather than the Volume name 000026.
51 - Max Vols limit in Pool off by one?
52 - Look at Preben's acl.c error handling code.
53 - See multiple-store.txt for Multiple Storage implementation
55 - Create a new GUI chapter explaining all the GUI programs.
56 - Tell the "restore" user when browsing is no longer possible.
57 - Add disk seeking on restore.
58 - Cancel command should include JobId in list of Jobs.
59 - Require restore via the restore command or make a restore Job
60 get the bootstrap file.
61 - Add dump of VolSessionId/Time and FileIndex with bls.
62 - Make bootstrap file handle multiple MediaTypes (SD)
63 - Add offline tape command to Bacula console.
64 - Add performance testing hooks
65 - Add Python writable variable for changing the Priority,
66 Client, Storage, JobStatus (error), ...
67 - Document that Bootstrap files can be written with cataloging
69 - Look at adding full Volume and Pool information to a Volume
70 label so that bscan can get *all* the info.
71 - Scratch Pool where the volumes can be re-assigned to any Pool.
72 - Upgrade to MySQL 4.1.1 See:
73 http://dev.mysql.com/doc/mysql/en/Server_SQL_mode.html
75 Enter MediaId or Volume name: 32
76 Enter new Volume name: DLT-20Dec04
77 Automatically selected Pool: Default
78 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...
79 Sending relabel command from "DLT-28Jun03" to "DLT-20Dec04" ...
80 block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
81 Error writing final EOF to tape. This tape may not be readable.
82 dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
83 askdir.c:219 NULL Volume name. This shouldn't happen!!!
84 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
86 Label command failed for Volume DLT-20Dec04.
87 Do not forget to mount the drive!!!
88 - Bug: if a job is manually scheduled to run later, it does not appear
89 in any status report and cannot be cancelled.
91 Regression tests (Jo):
92 - Add Pool/Storage override regression test.
93 - Add delete JobId to regression.
94 - Add a regression test for dbcheck.
95 - New test to add bscan to four-concurrent-jobs regression,
96 i.e. after the four-concurrent jobs zap the
97 database as is done in the bscan-test, then use bscan to
98 restore the database, do a restore and compare with the
100 - Add restore of specific JobId to regression (item 3
101 on the restore prompt)
102 - Add IPv6 to regression
103 - Add database test to regression. Test each function like delete,
106 - AntiVir can slow down backups on Win32 systems.
107 - Win32 systems with FAT32 can be much slower than NTFS for
108 more than 1000 files per directory.
112 === From Carsten Menke <bootsy52@gmx.net>
113 The bacula-devel list is CC'ed (I'm also subscribed to the list right now,
114 so I will also get the responses).
116 Following is a list of what I think in the situations where I'm faced with,
117 could be a usefull enhancement to bacula, which I'm certain other users will
118 benefit from as well.
120 1. NextJob/NextJobs Directive within a Job Resource in the form of
121 NextJobs = job1,job2.
124 I currently solved the problem with running multiple jobs each after each
125 by setting the Max Wait Time for a job to 8 hours, and give
126 the jobs different Priorities. However, there scenarios where
127 1 Job is directly depending on another job, so if the former job fails,
128 the job after it needn't to be run
129 while maybe other jobs should run despite of that
132 A Backup Job and a Verify job, if the backup job fails there is no need to run
133 the verify job, as the backup job already failed. However, one may like
134 to backup the Catalog to disk despite of that the main backup job failed.
137 I see that this is related to the Event Handlers which are on the ToDo
138 list, also it is maybe a good idea to check for the return value and
139 execute different actions based on the return value
141 2. Priorities also for the Schedule Resource
145 With this it is possible to run monthly jobs at the end of the month
146 instead of the beginning of the next month, so one could define
147 weekly and monthly pools to be run on Fridays and if there are
148 2 Jobs resulting on the same time, the one with the higher priority
149 takes precedence. This is also helpfull to implement a daily
150 rotation scheme with an additional 2 weeks changing weekly pool
154 Name = "NightlyBackup"
155 Run = Priority = 1,Pool=Weekly friday at 21:00
156 Run = Priority = 2,Pool=Weekly monthly on friday at 21:00
157 Run = Priority = 3,Pool=Weekly yearly on friday at 21:00
160 3. offline capability to bconsole
163 Currently I use a script which I execute within the last Job via the
164 RunAfterJob Directive, to release and eject the tape.
165 So I have to call bconsole "release=Storage-Name" and afterwards
166 mt -f /dev/nst0 eject to get the tape out.
168 If I have multiple Storage Devices, than these may not be /dev/nst0 and
169 I have to modify the script or call it with parameters etc.
170 This would actually not be needed, as everything is already defined
171 in bacula-sd.conf and if I can invoke bconsole with the
172 storage name via $1 in the script than I'm done and information is
175 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
179 For the reason mentioned in 3. to have the ability to call a
180 script with /scripts/foobar %s and in the script use $1
181 to pass the Storage Name to bconsole
183 5. Setting Volume State within a Job Resource
186 Instead of using "Maximum Volume Jobs" in the Pool Resource,
187 I would have the possibilty to define
188 in a Job Resource that after this certain job is run, the Volume State
189 should be set to "Volume State = Used", this give more flexibility (IMHO).
191 6. Localization of Bacula Messages
194 Unfortunatley many,many people I work with don't speak english very well.
195 So if at least the Reporting messages would be localized then they
196 would understand that they have to change the tape,etc. etc.
198 I volunteer to do the german translations, and if I can convince my wife also
199 french and Morre (western african language).
201 7. OK, this is evil, probably bound to security risks and maybe not possible
202 due to the design of bacula.
204 Implementation of Backtics ( `command` ) for shell comand execution to
205 the "Label Format" Directive.
209 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
210 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
211 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
212 the localized name for the day of the week appended to the
213 format string. Then I have the tape labeled automatically with weekday
214 name in the correct language.
216 - Can one write tapes faster with 8192 byte block sizes?
217 - Specify a single directory to restore.
218 - Implement Maximum Job Spool Size
219 - Document security problems with the same password for everyone in
220 rpm and Win32 releases.
221 - Browse generations of files.
222 - I've seen an error when my catalog's File table fills up. I
223 then have to recreate the File table with a larger maximum row
224 size. Relevant information is at
225 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
226 "Installing and Configuring MySQL" chapter should talk a bit
227 about this potential problem, and recommend a solution.
228 - For Solaris must use POSIX awk.
229 - Want speed of writing to tape while despooling.
230 - Supported autochanger:
238 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
239 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
240 - Add regex from http://www.pcre.org to Bacula for Win32.
241 - Use only shell tools no make in CDROM package.
242 - Document PostgreSQL performance problems bug 131.
244 - Document that ChangerDevice is used for Alert command.
245 - Include within include does it work?
246 - Implement a Pool of type Cleaning?
247 - Implement VolReadTime and VolWriteTime in SD
248 - Modify Backing up Your Database to include a bootstrap file.
249 - Think about making certain database errors fatal.
250 - Look at correcting the time jump in the scheduler for daylight
251 savings time changes.
252 - Add a "real" timer to network connections.
253 - Write non-optimized bsrs from the JobMedia and Media records,
254 even after Files are pruned.
255 - Promote to Full = Time period
256 - Despool attributes simultaneously with data in a separate
257 thread, rejoined at end of data spooling.
258 - Implement Files/Bytes,... stats for restore job.
259 - Implement Total Bytes Written, ... for restore job.
260 - Check dates entered by user for correctness (month/day/... ranges)
261 - Compress restore Volume listing by date and first file.
262 - Look at patches/bacula_db.b2z postgresql that loops during restore.
264 - Perhaps add read/write programs and/or plugins to FileSets.
265 - How to handle backing up portables ...
266 - Add some sort of guaranteed Interval for upgrading jobs.
267 - Can we write the state file after every job terminates? On Win32
268 the system crashes and the state file is not updated.
271 Documentation to do: (any release a little bit at a time)
272 - Doc to do unmount before removing magazine.
273 - Alternative to static linking "ldd prog" save all binaries listed,
274 restore them and point LD_LIBRARY_PATH to them.
275 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
276 - Document query file format.
277 - Add more documentation for bsr files.
278 - Document problems with Verify and pruning.
279 - Document how to use multiple databases.
280 - VXA drives have a "cleaning required"
281 indicator, but Exabyte recommends preventive cleaning after every 75
284 In this context, it should be noted that Exabyte has a command-line
285 vxatool utility available for free download. (The current version is
286 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
287 test the drive, unload tapes, change drive settings, flash new firmware,
289 Of particular interest in this context is that vxatool <device> -i will
290 report, among other details, the time since last cleaning in tape motion
291 minutes. This information can be retrieved (and settings changed, for
292 that matter) through the generic-SCSI device even when Bacula has the
293 regular tape device locked. (Needless to say, I don't recommend
294 changing tape settings while a job is running.)
295 - Lookup HP cleaning recommendations.
296 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
297 - Document doing table repair
300 Testing to do: (painful)
303 For 1.37 Testing/Documentation:
304 - Add bandwidth limiting.
305 - Add acks every once and a while from the SD to keep
306 the line from timing out.
307 - When an error in input occurs and conio beeps, you can back
308 up through the prompt.
309 - Detect fixed tape block mode during positioning by looking at
310 block numbers in btape "test". Possibly adjust in Bacula.
311 - Fix list volumes to output volume retention in some other
312 units, perhaps via a directive.
313 - If opening a tape in read/write mode fails attempt to open
314 it in read-only mode, and mark the tape for read only.
315 - Add a read-only mode to the mount option.
316 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
317 with multiple priorities.
318 - If you use restore replace=never, the directory attributes for
319 non-existent directories will not be restored properly.
321 - see lzma401.zip in others directory for new compression
323 - Minimal autochanger handling in Bacula and in btape.
324 - Look into how tar does not save sockets and the possiblity of
325 not saving them in Bacula (Martin Simmons reported this).
326 - Fix restore jobs so that multiple jobs can run if they
327 are not using the same tape(s).
328 - Allow the user to select JobType for manual pruning/purging.
329 - bscan does not put first of two volumes back with all info in
331 - Implement the FreeBSD nodump flag in chflags.
332 - Figure out how to make named console messages go only to that
333 console and to the non-restricted console (new console class?).
334 - Make restricted console prompt for password if *ask* is set or
335 perhaps if password is undefined.
336 - Implement "from ISO-date/time every x hours/days/weeks/months" in
341 MA = (last_MA * 3 + rate) / 4
342 rate = (bytes - last_bytes) / (runtime - last_runtime)
344 ==== from Marc Schoechlin
345 - the help-command should be more verbose
346 (it should explain the paramters of the different
348 -> it´s time-comsuming to consult the manual anytime
349 you need a special parameter
350 -> maybe it´s more easy to maintain this, if the
351 descriptions of that commands are outsourced to
353 - the cd-command should allow complete paths
354 i.e. cd /foo/bar/foo/bar
355 -> if a customer mails me the path to a certain file,
356 it´s faster to enter the specified directory
357 - if the password is not configured in bconsole.conf
358 you should be asked for it.
359 -> sometimes you like to do restore on a customer-machine
360 which shouldn´t know the password for bacula.
361 -> adding the password to the file favours admins
362 to forget to remove the password after usage
364 the protection of that file is less important
365 - long-listed-output of commands should be scrollable
366 like the unix more/less-command does
367 -> if someone runs 200 and more machines, the lists could
368 be a little long and complex
369 - command-output should be shown column by column
370 to reduce scrolling and to increase clarity
372 - lsmark should list the selected files with full
374 - wildcards for selecting and file and directories would be nice
375 - any actions should be interuptable with STRG+C
376 - command-expansion would be pretty cool
378 - When the replace Never option is set, new directory permissions
379 are not restored. See bug 213. To fix this requires creating a
380 list of newly restored directories so that those directory
381 permissions *can* be restored.
382 - Compaction of Disk space by "migrating" Volumes that have pruned
383 Jobs (what criteria? size, #jobs, time).
384 - Add prune all command
385 - Document fact that purge can destroy a part of a restore by purging
386 one volume while others remain valid -- perhaps mark Jobs.
387 - Add multiple-media-types.txt
388 - look at mxt-changer.html
389 - Make ? do a help command (no return needed).
390 - Implement restore directory.
391 - Document streams and how to implement them.
392 - Try not to re-backup a file if a new hard link is added.
393 - Add feature to backup hard links only, but not the data.
394 - Fix stream handling to be simpler.
395 - Add Priority and Bootstrap to Run a Job.
396 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
398 - Remove View FileSet button from Run a Job dialog.
399 - Handle prompt for restore job at end of Restore command.
400 - Add display of total selected files to Restore window.
401 - Add tree pane to left of window.
402 - Add progress meter.
403 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
404 - Document writing to a CD/DVD with Bacula.
405 - Add a "base" package to the window installer for pthreadsVCE.dll
406 which is needed by all packages.
407 - Add message to user to check for fixed block size when the forward
408 space test fails in btape.
409 - When unmarking a directory check if all files below are unmarked and
410 then remove the + flag -- in the restore tree.
411 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
412 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
413 - Revisit the question of multiple Volumes (disk) on a single device.
414 - Add a block copy option to bcopy.
415 - Investigate adding Mac Resource Forks.
416 - Finish work on Gnome restore GUI.
417 - Fix "llist jobid=xx" where no fileset or client exists.
419 it seems to be complaining about 12:00pm which should be a valid 12
420 hour time. I changed the time to 11:59am and everything works fine.
421 Also 12:00am works fine. 0:00pm also works (which I don't think
422 should). None of the values 12:00pm - 12:59pm work for that matter.
423 - Add level to estimate command.
424 - For each job type (Admin, Restore, ...) require only the really necessary
426 - Fix option 2 of restore -- list where file is backed up -- require Client,
427 then list last 20 backups.
428 - Pass Director resource name as an option to the Console.
429 - Add a "batch" mode to the Console (no unsolicited queries, ...).
430 - Add a .list all files in the restore tree (probably also a list all files)
431 Do both a long and short form.
432 - Allow browsing the catalog to see all versions of a file (with
433 stat data on each file).
434 - Restore attributes of directory if replace=never set but directory
436 - Use SHA1 on authentication if possible.
437 - See comtest-xxx.zip for Windows code to talk to USB.
438 - Add Events and Perl scripting.
439 - Add John's appended files:
440 Appended = { /files/server/logs/http/*log }
441 and such files would be treated as follows.On a FULL backup, they would
442 be backed up like any other file.On an INCREMENTAL backup, where a
443 previous INCREMENTAL or FULL was already in thecatalogue and the length
444 of the file wasgreater than the length of the last backup, only thedata
445 added since the last backup will be dumped.On an INCREMENTAL backup, if
446 the length of the file is less than thelength of the file with the same
447 name last backed up, the completefile is dumped.On Windows systems, with
448 creation date of files, we can be evensmarter about this and not count
449 entirely upon the length.On a restore, the full and all incrementals
450 since it will beapplied in sequence to restore the file.
451 - Allow for optional cancelling of SD and FD in case DIR
452 gets a fatal error. Requested by Jesse Guardiani <jesse@wingnet.net>
453 - Add "limit=n" for "list jobs"
454 - Check new HAVE_WIN32 open bits.
455 - Check if the tape has moved before writing.
456 - Handling removable disks -- see below:
457 - Keep track of tape use time, and report when cleaning is necessary.
458 - Add FromClient and ToClient keywords on restore command (or
459 BackupClient RestoreClient).
460 - Implement a JobSet, which groups any number of jobs. If the
461 JobSet is started, all the jobs are started together.
462 Allow Pool, Level, and Schedule overrides.
463 - Enhance cancel to timeout BSOCK packets after a specific delay.
464 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
465 ua_status.!!! Thanks to Alan Brown for this tip.
466 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
467 correctly for multiple simultaneous jobs.
468 - Correct code so that FileSet MD5 is calculated for < and | filename
470 - Implement the Media record flag that indicates that the Volume does disk
472 - Implement VolAddr, which is used when Volume is addressed like a disk,
473 and form it from VolFile and VolBlock.
474 - Make multiple restore jobs for multiple media types specifying
475 the proper storage type.
476 - Implement MediaType keyword in bsr?
477 - Fix fast block rejection (stored/read_record.c:118). It passes a null
478 pointer (rec) to try_repositioning().
479 - Look at extracting Win data from BackupRead.
480 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
481 which would take precidence over the Catalog "JobRetention".
482 - Implement Label Format in Add and Label console commands.
483 - Possibly up network buffers to 65K. Put on variable.
484 - Put email tape request delays on one or more variables. User wants
485 to cancel the job after a certain time interval. Maximum Mount Wait?
486 - Job, Client, Device, Pool, or Volume?
487 Is it possible to make this a directive which is *optional* in multiple
488 resources, like Level? If so, I think I'd make it an optional directive
489 in Job, Client, and Pool, with precedence such that Job overrides Client
490 which in turn overrides Pool.
492 - New Storage specifications:
493 - Want to write to multiple storage devices simultaneously
494 - Want to write to multiple storage devices sequentially (in one job)
495 - Want to read/write simultaneously
496 - Key is MediaType -- it must match
498 Passed to SD as a sort of BSR record called Storage Specification
502 MediaType -> Next MediaType
504 Device -> Next Device
506 Allow multiple Storage specifications
514 Allow Multiple Pool specifications (note, Pool currently
516 Allow Multiple MediaType specifications in Dir conf
517 Allow Multiple Device specifications in Dir conf
518 Perhaps keep this in a single SSR
519 Tie a Volume to a specific device by using a MediaType that
520 is contained in only one device.
521 In SD allow Device to have Multiple MediaTypes
523 - Ideas from Jerry Scharf:
524 First let's point out some big pluses that bacula has for this
526 more importantly it's active. Thank you so much for that
527 even more important, it's not flaky
528 it has an open access catalog, opening many possibilities
529 it's pushing toward heterogeneous systems capability
531 Macintosh file client
532 macs are an interesting niche, but I fear a server is a rathole
533 working bare iron recovery for windows
534 the option for inc/diff backups not reset on fileset revision
535 a) use both change and inode update time against base time
536 b) do the full catalog check (expensive but accurate)
537 sizing guide (how much system is needed to back up N systems/files)
538 consultants on using bacula in building a disaster recovery system
540 or how to get at fancy things that one could do with bacula
541 logwatch code for bacula logs (or similar)
542 linux distro inclusion of bacula (brings good and bad, but necessary)
543 win2k/XP server capability (icky but you asked)
544 support for Oracle database ??
546 - Look at adding SQL server and Exchange support for Windows.
547 - Each DVD-RAM disk would be a volume, just like each tape is
548 a volume. It's a 4.7GB media with random access, but there's nothing about
549 it that I can see that makes it so different than a tape from bacula's
550 perspective. Why couldn't I back up to a bare floppy as a volume (ignoring
552 - Make dev->file and dev->block_num signed integers so that -1 can
553 be an invalid value which happens with BSR.
554 - Create VolAddr for disk files in place of VolFile and VolBlock. This
555 is needed to properly specify ranges.
556 - Add progress of files/bytes to SD and FD.
557 - Print warning message if FileId > 4 billion
558 - do a "messages" before the first prompt in Console
559 - Add a date and time stamp at the beginning of every line in the
560 Job report (Volker Sauer).
561 - Client does not show busy during Estimate command.
562 - Implement Console mtx commands.
563 - Implement a Mount Command and an Unmount Command where
564 the users could specify a system command to be performed
565 to do the mount, after which Bacula could attempt to
566 read the device. This is for Removeable media such as a CDROM.
567 - Most likely, this mount command would be invoked explicitly
568 by the user using the current Console "mount" and "unmount"
569 commands -- the Storage Daemon would do the right thing
570 depending on the exact nature of the device.
571 - As with tape drives, when Bacula wanted a new removable
572 disk mounted, it would unmount the old one, and send a message
573 to the user, who would then use "mount" as described above
574 once he had actually inserted the disk.
575 - Implement dump/print label to UA
576 - Spool to disk only when the tape is full, then when a tape is hung move
578 - bextract is sending everything to the log file ****FIXME****
579 - Allow multiple Storage specifications (or multiple names on
580 a single Storage specification) in the Job record. Thus a job
581 can be backed up to a number of storage devices.
582 - Implement some way for the File daemon to contact the Director
583 to start a job or pass its DHCP obtained IP number.
584 - Implement a query tape prompt/replace feature for a console
585 - Copy console @ code to gnome2-console
586 - Make AES the only encryption algorithm see
587 http://csrc.nist.gov/CryptoToolkit/aes/). It's
588 an officially adopted standard, has survived peer
589 review, and provides keys up to 256 bits.
590 - Take a careful look at SetACL http://setacl.sourceforge.net
591 - Take a careful look at Level for the estimate command, maybe make
592 it a command line option.
593 - Add Volume name to "I cannot write on this volume because"
594 - Make tree walk routines like cd, ls, ... more user friendly
595 by handling spaces better.
596 - Make sure that Bacula rechecks the tape after the 20 min wait.
597 - Set IO_NOWAIT on Bacula TCP/IP packets.
598 - Try doing a raw partition backup and restore by mounting a
601 Yes, it would allow to highly automatic the request for new tapes. If a
602 tape is empty, bacula reads the barcodes (native or simulated), and if
603 an unused tape is found, it runs the label command with all the
604 necessary parameters.
606 By the way can bacula automatically "move" an empty/purged volume say
607 in the "short" pool to the "long" pool if this pool runs out of volume
609 - What to do about "list files job=xxx".
610 - Make Dmsg look at global before calling subroutine.
611 - Get and test MySQL 4.0
612 - Look at how fuser works and /proc/PID/fd that is how Nic found the
613 file descriptor leak in Bacula.
614 - Implement WrapCounters in Counters.
615 - Add heartbeat from FD to SD if hb interval expires.
616 - Can we dynamically change FileSets?
617 - If pool specified to label command and Label Format is specified,
618 automatically generate the Volume name.
619 - Why can't SQL do the filename sort for restore?
620 - Look into Microsoft Volume Shadowcopy Service VSS for backing
621 up system state components (Active Directory, System Volume, ...)
622 - Add ExhautiveRestoreSearch
623 - Look at the possibility of loading only the necessary
624 data into the restore tree (i.e. do it one directory at a
625 time as the user walks through the tree).
626 - Possibly use the hash code if the user selects all for a restore command.
627 - Fix "restore all" to bypass building the tree.
628 - Prohibit backing up archive device (findlib/find_one.c:128)
629 - Implement Release Device in the Job resource to unmount a drive.
630 - Implement Acquire Device in the Job resource to mount a drive,
631 be sure this works with admin jobs so that the user can get
632 prompted to insert the correct tape. Possibly some way to say to
633 run the job but don't save the files.
634 - Make things like list where a file is saved case independent for
637 - Use autochanger to handle multiple devices.
638 - Add SuSE install doc to list.
639 - Check and rechedk "Invalid block number"
640 - User wants to NOT backup up certain big files (email files).
641 - Maybe remove multiple simultaneous devices code in SD.
642 - On Windows with very long path names, it may be impossible to create
643 a file (and thus restore it) because the total length is too long.
644 We must cd into the directory then create the file without the
646 - Implement a Recycle command
647 - Add client name to cram-md5 challenge so Director can immediately
648 verify if it is the correct client.
649 - Audit all UA commands to ensure that we always prompt where possible.
650 - Make bootstrap filename unique.
651 - Test a second language e.g. french.
652 - Start working on Base jobs.
653 - Implement UnsavedFiles DB record.
654 - Implement argc/argv for daemon command line scanning using table driven
656 - From Phil Stracchino:
657 It would probably be a per-client option, and would be called
658 something like, say, "Automatically purge obsoleted jobs". What it
659 would do is, when you successfully complete a Differential backup of a
660 client, it would automatically purge all Incremental backups for that
661 client that are rendered redundant by that Differential. Likewise,
662 when a Full backup on a client completed, it would automatically purge
663 all Differential and Incremental jobs obsoleted by that Full backup.
664 This would let people minimize the number of tapes they're keeping on
665 hand without having to master the art of retention times.
666 - Implement a M_SECURITY message class.
667 - When doing a Backup send all attributes back to the Director, who
668 would then figure out what files have been deleted.
669 - Currently in mount.c:236 the SD simply creates a Volume. It should have
670 explicit permission to do so. It should also mark the tape in error
671 if there is an error.
672 - SD Bytes Read is wrong.
673 - Investigate doing RAW backup of Win32 partition.
674 - Cancel waiting for Client connect in SD if FD goes away.
676 - Implement timeout in response() when it should come quickly.
677 - Implement console @echo command.
678 - Implement a Slot priority (loaded/not loaded).
679 - Implement "vacation" Incremental only saves.
680 - Implement single pane restore (much like the Gftp panes).
681 - Implement Automatic Mount even in operator wait.
682 - Implement create "FileSet"?
683 - Implement restore "current system", but take all files without
684 doing selection tree -- so that jobs without File records can
686 - Add prefixlinks to where or not where absolute links to FD.
687 - Issue message to mount a new tape before the rewind.
688 - Simplified client job initiation for portables.
689 - If SD cannot open a drive, make it periodically retry.
690 - Add more of the config info to the tape label.
692 - If tape is marked read-only, then try opening it read-only rather than
693 failing, and remember that it cannot be written.
694 - Refine SD waiting output:
695 Device is being positioned
696 > Device is being positioned for append
697 > Device is being positioned to file x
699 - Figure out some way to estimate output size and to avoid splitting
700 a backup across two Volumes -- this could be useful for writing CDROMs
701 where you really prefer not to have it split -- not serious.
702 - Have SD compute MD5 or SHA1 and compare to what FD computes.
703 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
704 actual data on the Volume and compare it.
705 - Implement Bacula plugins -- design API
706 - Make bcopy read through bad tape records.
707 - Program files (i.e. execute a program to read/write files).
708 Pass read date of last backup, size of file last time.
709 - Add Signature type to File DB record.
710 - CD into subdirectory when open()ing files for backup to
711 speed up things. Test with testfind().
712 - Priority job to go to top of list.
713 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
714 - Implement some way for the Console to dynamically create a job.
715 - Restore to a particular time -- e.g. before date, after date.
716 - Solaris -I on tar for include list
717 - Need a verbose mode in restore, perhaps to bsr.
718 - bscan without -v is too quiet -- perhaps show jobs.
719 - Add code to reject whole blocks if not wanted on restore.
720 - Check if we can increase Bacula FD priorty in Win2000
721 - Make sure the MaxVolFiles is fully implemented in SD
722 - Check if both CatalogFiles and UseCatalog are set to SD.
723 - Figure out how to do a bare metal Windows restore
724 - Possibly add email to Watchdog if drive is unmounted too
725 long and a job is waiting on the drive.
726 - After unmount, if restore job started, ask to mount.
727 - Convert all %x substitution variables, which are hard to remember
728 and read to %(variable-name). Idea from TMDA.
729 - Remove NextId for SQLite. Optimize.
730 - Move all SQL statements into a single location.
731 - Add UA rc and history files.

746 - Verify level=Volume (scan only), level=Data (compare of data to file).
747 Verify level=Catalog, level=InitCatalog
749 - Add keyword search to show command in Console.
750 - Events : tape has more than xxx bytes.
751 - Complete code in Bacula Resources -- this will permit
752 reading a new config file at any time.
753 - Handle ctl-c in Console
754 - Implement script driven addition of File daemon to config files.
755 - Think about how to make Bacula work better with File (non-tape) archives.
756 - Write Unix emulator for Windows.
757 - Put memory utilization in Status output of each daemon
758 if full status requested or if some level of debug on.

837 - Store info on each file system type (probably in the job header on tape.
838 This could be the output of df; or perhaps some sort of /etc/mtab record.
840 ========= ideas ===============
841 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
842 To: <kern@sibbald.com>
843 Subject: RE: [Bacula-users] future large programming jobs
844 Date: Thu, 26 Feb 2004 11:34:54 -0600
846 I noticed the subject thread and thought I would offer the following
847 merely as sources of ideas, i.e. something to think about, not even as
848 strong as a request. In my former life (before retiring) I often
849 dealt with backups and storage management issues/products as a
850 developer and as a consultant. I am currently migrating my personal
851 network from amanda to bacula specifically because of the ability to
852 cross media boundaries during storing backups.
853 Are you familiar with the commercial product called ADSM (I think IBM
854 now sells it under the Tivoli label)? It has a couple of interesting
855 ideas that may apply to the following topics.
857 1. Migration: Consider that when you need to restore a system, there
858 may be pressure to hurry. If all the information for a single client
859 can eventually end up on the same media (and in chronological order),
860 the restore is facillitated by not having to search past information
861 from other clients. ADSM has the concept of "client affinity" that
862 may be associated with it's storage pools. It seems to me that this
863 concept (as an optional feature) might fit in your architecture for
866 ADSM also has the concept of defining one or more storage pools as
867 "copy pools" (almost mirrors, but only in the sense of contents).
868 These pools provide the ability to have duplicte data stored both
869 onsite and offsite. The copy process can be scheduled to be handled
870 by their storage manager during periods when there is no backup
871 activity. Again, the migration process might be a place to consider
872 implementing something like this.
875 > It strikes me that it would be very nice to be able to do things
877 > have the Job(s) backing up the machines run, and once they have all

883 > mechanism described below would probably make it very easy.
885 This is the goal. In the first step (before events), you simply
887 the Migration to tape later.
889 2. Base jobs: In ADSM, each copy of each stored file is tracked in
890 the database. Once a file (unique by path and metadata such as dates,
891 size, ownership, etc.) is in a copy pool, no more copies are made. In
892 other words, when you start ADSM, it begins like your concept of a
893 base job. After that it is in the "incremental" mode. You can
894 configure the number of "generations" of files to be retained, plus a
895 retention date after which even old generations are purged. The
896 database tracks the contents of media and projects the percentage of
897 each volume that is valid. When the valid content of a volume drops
898 below a configured percentage, the valid data are migrated to another
899 volume and the old volume is marked as empty. Note, this requires
900 ADSM to have an idea of the contents of a client, i.e. marking the
901 database when an existing file was deleted, but this would solve your
902 issue of restoring a client without restoring deleted files.
904 This is pretty far from what bacula now does, but if you are going to
905 rip things up for Base jobs,.....
906 Also, the benefits of this are huge for very large shops, especially
907 with media robots, but are a pain for shops with manual media
911 > Base jobs sound pretty useful, but I'm not dying for them.
913 Nobody is dying for them, but when you see what it does, you will die
916 3. Restoring deleted files: Since I think my comments in (2) above
917 have low probability of implementation, I'll also suggest that you
918 could approach the issue of deleted files by a mechanism of having the
919 fd report to the dir, a list of all files on the client for every
920 backup job. The dir could note in the database entry for each file
921 the date that the file was seen. Then if a restore as of date X takes
922 place, only files that exist from before X until after X would be
923 restored. Probably the major cost here is the extra date container in
924 each row of the files table.
926 Thanks for "listening". I hope some of this helps. If you want to
927 contact me, please send me an email - I read some but not all of the
928 mailing list traffic and might miss a reply there.
930 Please accept my compliments for bacula. It is doing a great job for
931 me!! I sympathize with you in the need to wrestle with excelence in
932 execution vs. excelence in feature inclusion.
937 ==============================
940 - Design at hierarchial storage for Bacula. Migration and Clone.
941 - Implement FSM (File System Modules).
942 - Audit M_ error codes to ensure they are correct and consistent.
943 - Add variable break characters to lex analyzer.
944 Either a bit mask or a string of chars so that
945 the caller can change the break characters.
946 - Make a single T_BREAK to replace T_COMMA, etc.
947 - Ensure that File daemon and Storage daemon can
948 continue a save if the Director goes down (this
949 is NOT currently the case). Must detect socket error,
950 buffer messages for later.
951 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
952 - Add ability to backup to two Storage devices (two SD sessions) at
953 the same time -- e.g. onsite, offsite.
954 - Add the ability to consolidate old backup sets (basically do a restore
955 to tape and appropriately update the catalog). Compress Volume sets.
956 Might need to spool via file is only one drive is available.
957 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
958 someway to do so with every volume that has less than x% valid
962 Migration: Move a backup from one Volume to another
963 Clone: Copy a backup -- two Volumes
965 Bacula Migration is based on Jobs (apparently Networker is file by file).
967 Migration triggered by:
971 Highwater mark (keep total size)
976 ======================================================
978 It is somewhat like a Full save becomes an incremental since
979 the Base job (or jobs) plus other non-base files.
981 - A Base backup is same as Full backup, just different type.
982 - New BaseFiles table that contains:
984 BaseJobId - Base JobId referenced for this FileId (needed ???)
985 JobId - JobId currently running
986 FileId - File not backed up, exists in Base Job
987 FileIndex - FileIndex from Base Job.
988 i.e. for each base file that exists but is not saved because
989 it has not changed, the File daemon sends the JobId, BaseId,
990 FileId, FileIndex back to the Director who creates the DB entry.
991 - To initiate a Base save, the Director sends the FD
992 the FileId, and full filename for each file in the Base.
993 - When the FD finds a Base file, he requests the Director to
994 send him the full File entry (stat packet plus MD5), or
995 conversely, the FD sends it to the Director and the Director
996 says yes or no. This can be quite rapid if the FileId is kept
997 by the FD for each Base Filename.
998 - It is probably better to have the comparison done by the FD
999 despite the fact that the File entry must be sent across the
1001 - An alternative would be to send the FD the whole File entry
1002 from the start. The disadvantage is that it requires a lot of
1003 space. The advantage is that it requires less communications
1005 - The Job record must be updated to indicate that one or more
1007 - At end of Job, FD returns:
1008 1. Count of base files/bytes not written to tape (i.e. matches)
1009 2. Count of base file that were saved i.e. had changed.
1010 - No tape record would be written for a Base file that matches, in the
1011 same way that no tape record is written for Incremental jobs where
1012 the file is not saved because it is unchanged.
1013 - On a restore, all the Base file records must explicitly be
1014 found from the BaseFile tape. I.e. for each Full save that is marked
1015 to have one or more Base Jobs, search the BaseFile for all occurrences
1017 - An optimization might be to make the BaseFile have:
1023 This would avoid the need to explicitly fetch each File record for
1024 the Base job. The Base Job record will be fetched to get the
1025 VolSessionId and VolSessionTime.
1026 =========================================================
1029 ==========================================================
1031 For each Incremental job that is run, there may be files that
1032 were found but not saved because they were locked (this applies
1033 only to Windows). Such a system could send back to the Director
1034 a list of Unsaved files.
1036 - New UnSavedFiles table that contains:
1040 - Then in the next Incremental job, the list of Unsaved Files will be
1041 feed to the FD, who will ensure that they are explicitly chosen even
1042 if standard date/time check would not have selected them.
1043 =============================================================
1046 Done: (see kernsdone for more)
1049 - John's Full save failed with 1.32c FD and 1.31 Dir no FD status,
1050 and no error message.
1051 - Add fd and st as Console keywords.
1052 - Recycling volume with a Slot requires an operator intervention:
1053 rufus-dir: Start Backup JobId 18, Job=kernsave.2003-11-01_21.23.52
1054 rufus-dir: Pruned 1 Job on Volume Vol01 from catalog.
1055 rufus-dir: There are no Jobs associated with Volume Vol01. Marking it purged.
1056 rufus-dir: Recycled volume "Vol01"
1057 rufus-sd: Please mount Volume "Vol01" on Storage Device "DDS-4" for Job kernsave.2003-11-01_21.23.52
1058 Use "mount" command to release Job.
1059 - Implement Dan's bacula script (email of 26 Oct).
1060 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
1061 - Edit the Client/Storage name into authentication failure messages.
1062 - Fix packet too big problem. This is most likely a Windows TCP stack
1064 - Implement ClientRunBeforeJob and ClientRunAfterJob.
1065 - Implement forward spacing block/file: position_device(bsr) --
1066 just before read_block_from_device();

1106 (just to verify it remembers where it came from, however it can be
1107 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1109 There needs to be a table of drive # to devices somewhere - If there are
1110 multiple changers or drives there may not be a 1:1 correspondance between
1111 changer drive number and system device name - and depending on the way the
1112 drives are hooked up to scsi busses, they may not be linearly numbered
1113 from an offset point either.something like
1115 Autochanger drives = 2
1116 Autochanger drive 0 = /dev/nst1
1117 Autochanger drive 1 = /dev/nst2
1118 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1119 times, not just for multidrive changers. For a 1 drive changer, that's
1125 MTX's manpage (1.2.15):
1126 unload [<slotnum>] [ <drivenum> ]
1127 Unloads media from drive <drivenum> into slot
1128 <slotnum>. If <drivenum> is omitted, defaults to
1129 drive 0 (as do all commands). If <slotnum> is
1130 omitted, defaults to the slot that the drive was
1131 loaded from. Note that there's currently no way
1132 to say 'unload drive 1's media to the slot it
1133 came from', other than to explicitly use that

1172 Handling removable disks
1174 From: Karl Cunningham <karlc@keckec.com>
1176 My backups are only to hard disk these days, in removable bays. This is my
1177 idea of how a backup to hard disk would work more smoothly. Some of these
1178 things Bacula does already, but I mention them for completeness. If others
1179 have better ways to do this, I'd like to hear about it.
1181 1. Accommodate several disks, rotated similar to how tapes are. Identified
1182 by partition volume ID or perhaps by the name of a subdirectory.
1183 2. Abort & notify the admin if the wrong disk is in the bay.
1184 3. Write backups to different subdirectories for each machine to be backed
1186 4. Volumes (files) get created as needed in the proper subdirectory, one
1188 5. When a disk is recycled, remove or zero all old backup files. This is
1189 important as the disk being recycled may be close to full. This may be
1190 better done manually since the backup files for many machines may be
1191 scattered in many subdirectories.
1196 - Save mount point for directories not traversed with onefs=yes.
1197 - Add seconds to start and end times in the Job report output.
1198 - if 2 concurrent backups are attempted on the same tape
1199 drive (autoloader) into different tape pools, one of them will exit
1200 fatally instead of halting until the drive is idle
1201 - Update StartTime if job held in Job Queue.
1202 - Look at www.nu2.nu/pebuilder as a helper for full windows
1203 bare metal restore. (done by Scott)
1204 - Fix orphanned buffers:
1205 Orphaned buffer: 24 bytes allocated at line 808 of rufus-dir job.c
1206 Orphaned buffer: 40 bytes allocated at line 45 of rufus-dir alist.c
1207 - Implement Preben's suggestion to add
1208 File System Types = ext2, ext3
1209 to FileSets, thus simplifying backup of *all* local partitions.
