26 Suggestions for Preben:
27 - Look at adding Client run command that will use the
28 port opened by the client.
29 - Implement WildFile and WildDir to solve problem of
30 saving only *.doc files.
31 - Bootstrap from JobMedia records.
32 - Optimized bootstrap.
35 - Look at Preben's acl.c error handling code.
36 - See multiple-store.txt for Multiple Storage implementation
38 - Create a new GUI chapter explaining all the GUI programs.
39 - Tell the "restore" user when browsing is no longer possible.
40 - Add disk seeking on restore.
41 - Cancel command should include JobId in list of Jobs.
42 - Require restore via the restore command or make a restore Job
43 get the bootstrap file.
44 - Add dump of VolSessionId/Time and FileIndex with bls.
45 - Make bootstrap file handle multiple MediaTypes (SD)
46 - Add offline tape command to Bacula console.
47 - Add performance testing hooks
48 - Add Python writable variable for changing the Priority,
49 Client, Storage, JobStatus (error), ...
50 - Document that Bootstrap files can be written with cataloging
52 - Look at adding full Volume and Pool information to a Volume
53 label so that bscan can get *all* the info.
54 - Scratch Pool where the volumes can be re-assigned to any Pool.
55 - Upgrade to MySQL 4.1.1 See:
56 http://dev.mysql.com/doc/mysql/en/Server_SQL_mode.html
58 Enter MediaId or Volume name: 32
59 Enter new Volume name: DLT-20Dec04
60 Automatically selected Pool: Default
61 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...
62 Sending relabel command from "DLT-28Jun03" to "DLT-20Dec04" ...
63 block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
64 Error writing final EOF to tape. This tape may not be readable.
65 dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
66 askdir.c:219 NULL Volume name. This shouldn't happen!!!
67 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
69 Label command failed for Volume DLT-20Dec04.
70 Do not forget to mount the drive!!!
71 - Bug: if a job is manually scheduled to run later, it does not appear
72 in any status report and cannot be cancelled.
74 Regression tests (Jo):
75 - Add Pool/Storage override regression test.
76 - Add delete JobId to regression.
77 - Add a regression test for dbcheck.
78 - New test to add bscan to four-concurrent-jobs regression,
79 i.e. after the four-concurrent jobs zap the
80 database as is done in the bscan-test, then use bscan to
81 restore the database, do a restore and compare with the
83 - Add restore of specific JobId to regression (item 3
84 on the restore prompt)
85 - Add IPv6 to regression
86 - Add database test to regression. Test each function like delete,
89 - AntiVir can slow down backups on Win32 systems.
90 - Win32 systems with FAT32 can be much slower than NTFS for
91 more than 1000 files per directory.
95 === From Carsten Menke <bootsy52@gmx.net>
96 The bacula-devel list is CC'ed (I'm also subscribed to the list right now,
97 so I will also get the responses).
99 Following is a list of what I think in the situations where I'm faced with,
100 could be a usefull enhancement to bacula, which I'm certain other users will
101 benefit from as well.
103 1. NextJob/NextJobs Directive within a Job Resource in the form of
104 NextJobs = job1,job2.
107 I currently solved the problem with running multiple jobs each after each
108 by setting the Max Wait Time for a job to 8 hours, and give
109 the jobs different Priorities. However, there scenarios where
110 1 Job is directly depending on another job, so if the former job fails,
111 the job after it needn't to be run
112 while maybe other jobs should run despite of that
115 A Backup Job and a Verify job, if the backup job fails there is no need to run
116 the verify job, as the backup job already failed. However, one may like
117 to backup the Catalog to disk despite of that the main backup job failed.
120 I see that this is related to the Event Handlers which are on the ToDo
121 list, also it is maybe a good idea to check for the return value and
122 execute different actions based on the return value
124 2. Priorities also for the Schedule Resource
128 With this it is possible to run monthly jobs at the end of the month
129 instead of the beginning of the next month, so one could define
130 weekly and monthly pools to be run on Fridays and if there are
131 2 Jobs resulting on the same time, the one with the higher priority
132 takes precedence. This is also helpfull to implement a daily
133 rotation scheme with an additional 2 weeks changing weekly pool
137 Name = "NightlyBackup"
138 Run = Priority = 1,Pool=Weekly friday at 21:00
139 Run = Priority = 2,Pool=Weekly monthly on friday at 21:00
140 Run = Priority = 3,Pool=Weekly yearly on friday at 21:00
143 3. offline capability to bconsole
146 Currently I use a script which I execute within the last Job via the
147 RunAfterJob Directive, to release and eject the tape.
148 So I have to call bconsole "release=Storage-Name" and afterwards
149 mt -f /dev/nst0 eject to get the tape out.
151 If I have multiple Storage Devices, than these may not be /dev/nst0 and
152 I have to modify the script or call it with parameters etc.
153 This would actually not be needed, as everything is already defined
154 in bacula-sd.conf and if I can invoke bconsole with the
155 storage name via $1 in the script than I'm done and information is
158 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
162 For the reason mentioned in 3. to have the ability to call a
163 script with /scripts/foobar %s and in the script use $1
164 to pass the Storage Name to bconsole
166 5. Setting Volume State within a Job Resource
169 Instead of using "Maximum Volume Jobs" in the Pool Resource,
170 I would have the possibilty to define
171 in a Job Resource that after this certain job is run, the Volume State
172 should be set to "Volume State = Used", this give more flexibility (IMHO).
174 6. Localization of Bacula Messages
177 Unfortunatley many,many people I work with don't speak english very well.
178 So if at least the Reporting messages would be localized then they
179 would understand that they have to change the tape,etc. etc.
181 I volunteer to do the german translations, and if I can convince my wife also
182 french and Morre (western african language).
184 7. OK, this is evil, probably bound to security risks and maybe not possible
185 due to the design of bacula.
187 Implementation of Backtics ( `command` ) for shell comand execution to
188 the "Label Format" Directive.
192 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
193 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
194 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
195 the localized name for the day of the week appended to the
196 format string. Then I have the tape labeled automatically with weekday
197 name in the correct language.
199 - Can one write tapes faster with 8192 byte block sizes?
200 - Specify a single directory to restore.
201 - Implement Maximum Job Spool Size
202 - Document security problems with the same password for everyone in
203 rpm and Win32 releases.
204 - Browse generations of files.
205 - I've seen an error when my catalog's File table fills up. I
206 then have to recreate the File table with a larger maximum row
207 size. Relevant information is at
208 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
209 "Installing and Configuring MySQL" chapter should talk a bit
210 about this potential problem, and recommend a solution.
211 - For Solaris must use POSIX awk.
212 - Want speed of writing to tape while despooling.
213 - Supported autochanger:
221 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
222 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
223 - Add regex from http://www.pcre.org to Bacula for Win32.
224 - Use only shell tools no make in CDROM package.
225 - Document PostgreSQL performance problems bug 131.
227 - Document that ChangerDevice is used for Alert command.
228 - Include within include does it work?
229 - Implement a Pool of type Cleaning?
230 - Implement VolReadTime and VolWriteTime in SD
231 - Modify Backing up Your Database to include a bootstrap file.
232 - Think about making certain database errors fatal.
233 - Look at correcting the time jump in the scheduler for daylight
234 savings time changes.
235 - Add a "real" timer to network connections.
236 - Write non-optimized bsrs from the JobMedia and Media records,
237 even after Files are pruned.
238 - Promote to Full = Time period
239 - Despool attributes simultaneously with data in a separate
240 thread, rejoined at end of data spooling.
241 - Implement Files/Bytes,... stats for restore job.
242 - Implement Total Bytes Written, ... for restore job.
243 - Check dates entered by user for correctness (month/day/... ranges)
244 - Compress restore Volume listing by date and first file.
245 - Look at patches/bacula_db.b2z postgresql that loops during restore.
247 - Perhaps add read/write programs and/or plugins to FileSets.
248 - How to handle backing up portables ...
249 - Add some sort of guaranteed Interval for upgrading jobs.
250 - Can we write the state file after every job terminates? On Win32
251 the system crashes and the state file is not updated.
254 Documentation to do: (any release a little bit at a time)
255 - Doc to do unmount before removing magazine.
256 - Alternative to static linking "ldd prog" save all binaries listed,
257 restore them and point LD_LIBRARY_PATH to them.
258 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
259 - Document query file format.
260 - Add more documentation for bsr files.
261 - Document problems with Verify and pruning.
262 - Document how to use multiple databases.
263 - VXA drives have a "cleaning required"
264 indicator, but Exabyte recommends preventive cleaning after every 75
267 In this context, it should be noted that Exabyte has a command-line
268 vxatool utility available for free download. (The current version is
269 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
270 test the drive, unload tapes, change drive settings, flash new firmware,
272 Of particular interest in this context is that vxatool <device> -i will
273 report, among other details, the time since last cleaning in tape motion
274 minutes. This information can be retrieved (and settings changed, for
275 that matter) through the generic-SCSI device even when Bacula has the
276 regular tape device locked. (Needless to say, I don't recommend
277 changing tape settings while a job is running.)
278 - Lookup HP cleaning recommendations.
279 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
280 - Document doing table repair
283 Testing to do: (painful)
286 For 1.37 Testing/Documentation:
287 - Add bandwidth limiting.
288 - Add acks every once and a while from the SD to keep
289 the line from timing out.
290 - When an error in input occurs and conio beeps, you can back
291 up through the prompt.
292 - Detect fixed tape block mode during positioning by looking at
293 block numbers in btape "test". Possibly adjust in Bacula.
294 - Fix list volumes to output volume retention in some other
295 units, perhaps via a directive.
296 - If opening a tape in read/write mode fails attempt to open
297 it in read-only mode, and mark the tape for read only.
298 - Add a read-only mode to the mount option.
299 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
300 with multiple priorities.
301 - If you use restore replace=never, the directory attributes for
302 non-existent directories will not be restored properly.
304 - see lzma401.zip in others directory for new compression
306 - Minimal autochanger handling in Bacula and in btape.
307 - Look into how tar does not save sockets and the possiblity of
308 not saving them in Bacula (Martin Simmons reported this).
309 - Fix restore jobs so that multiple jobs can run if they
310 are not using the same tape(s).
311 - Allow the user to select JobType for manual pruning/purging.
312 - bscan does not put first of two volumes back with all info in
314 - Implement the FreeBSD nodump flag in chflags.
315 - Figure out how to make named console messages go only to that
316 console and to the non-restricted console (new console class?).
317 - Make restricted console prompt for password if *ask* is set or
318 perhaps if password is undefined.
319 - Implement "from ISO-date/time every x hours/days/weeks/months" in
324 MA = (last_MA * 3 + rate) / 4
325 rate = (bytes - last_bytes) / (runtime - last_runtime)
327 ==== from Marc Schoechlin
328 - the help-command should be more verbose
329 (it should explain the paramters of the different
331 -> it´s time-comsuming to consult the manual anytime
332 you need a special parameter
333 -> maybe it´s more easy to maintain this, if the
334 descriptions of that commands are outsourced to
336 - the cd-command should allow complete paths
337 i.e. cd /foo/bar/foo/bar
338 -> if a customer mails me the path to a certain file,
339 it´s faster to enter the specified directory
340 - if the password is not configured in bconsole.conf
341 you should be asked for it.
342 -> sometimes you like to do restore on a customer-machine
343 which shouldn´t know the password for bacula.
344 -> adding the password to the file favours admins
345 to forget to remove the password after usage
347 the protection of that file is less important
348 - long-listed-output of commands should be scrollable
349 like the unix more/less-command does
350 -> if someone runs 200 and more machines, the lists could
351 be a little long and complex
352 - command-output should be shown column by column
353 to reduce scrolling and to increase clarity
355 - lsmark should list the selected files with full
357 - wildcards for selecting and file and directories would be nice
358 - any actions should be interuptable with STRG+C
359 - command-expansion would be pretty cool
361 - Compaction of Disk space by "migrating" Volumes that have pruned
362 Jobs (what criteria? size, #jobs, time).
363 - Add prune all command
364 - Document fact that purge can destroy a part of a restore by purging
365 one volume while others remain valid -- perhaps mark Jobs.
366 - Add multiple-media-types.txt
367 - look at mxt-changer.html
368 - Make ? do a help command (no return needed).
369 - Implement restore directory.
370 - Document streams and how to implement them.
371 - Try not to re-backup a file if a new hard link is added.
372 - Add feature to backup hard links only, but not the data.
373 - Fix stream handling to be simpler.
374 - Add Priority and Bootstrap to Run a Job.
375 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
377 - Remove View FileSet button from Run a Job dialog.
378 - Handle prompt for restore job at end of Restore command.
379 - Add display of total selected files to Restore window.
380 - Add tree pane to left of window.
381 - Add progress meter.
382 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
383 - Document writing to a CD/DVD with Bacula.
384 - Add a "base" package to the window installer for pthreadsVCE.dll
385 which is needed by all packages.
386 - Add message to user to check for fixed block size when the forward
387 space test fails in btape.
388 - When unmarking a directory check if all files below are unmarked and
389 then remove the + flag -- in the restore tree.
390 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
391 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
392 - Revisit the question of multiple Volumes (disk) on a single device.
393 - Add a block copy option to bcopy.
394 - Investigate adding Mac Resource Forks.
395 - Finish work on Gnome restore GUI.
396 - Fix "llist jobid=xx" where no fileset or client exists.
398 it seems to be complaining about 12:00pm which should be a valid 12
399 hour time. I changed the time to 11:59am and everything works fine.
400 Also 12:00am works fine. 0:00pm also works (which I don't think
401 should). None of the values 12:00pm - 12:59pm work for that matter.
402 - Add level to estimate command.
403 - For each job type (Admin, Restore, ...) require only the really necessary
405 - Fix option 2 of restore -- list where file is backed up -- require Client,
406 then list last 20 backups.
407 - Pass Director resource name as an option to the Console.
408 - Add a "batch" mode to the Console (no unsolicited queries, ...).
409 - Add a .list all files in the restore tree (probably also a list all files)
410 Do both a long and short form.
411 - Allow browsing the catalog to see all versions of a file (with
412 stat data on each file).
413 - Restore attributes of directory if replace=never set but directory
415 - Use SHA1 on authentication if possible.
416 - See comtest-xxx.zip for Windows code to talk to USB.
417 - Add Events and Perl scripting.
418 - Add John's appended files:
419 Appended = { /files/server/logs/http/*log }
420 and such files would be treated as follows.On a FULL backup, they would
421 be backed up like any other file.On an INCREMENTAL backup, where a
422 previous INCREMENTAL or FULL was already in thecatalogue and the length
423 of the file wasgreater than the length of the last backup, only thedata
424 added since the last backup will be dumped.On an INCREMENTAL backup, if
425 the length of the file is less than thelength of the file with the same
426 name last backed up, the completefile is dumped.On Windows systems, with
427 creation date of files, we can be evensmarter about this and not count
428 entirely upon the length.On a restore, the full and all incrementals
429 since it will beapplied in sequence to restore the file.
430 - Allow for optional cancelling of SD and FD in case DIR
431 gets a fatal error. Requested by Jesse Guardiani <jesse@wingnet.net>
432 - Add "limit=n" for "list jobs"
433 - Check new HAVE_WIN32 open bits.
434 - Check if the tape has moved before writing.
435 - Handling removable disks -- see below:
436 - Keep track of tape use time, and report when cleaning is necessary.
437 - Add FromClient and ToClient keywords on restore command (or
438 BackupClient RestoreClient).
439 - Implement a JobSet, which groups any number of jobs. If the
440 JobSet is started, all the jobs are started together.
441 Allow Pool, Level, and Schedule overrides.
442 - Enhance cancel to timeout BSOCK packets after a specific delay.
443 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
444 ua_status.!!! Thanks to Alan Brown for this tip.
445 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
446 correctly for multiple simultaneous jobs.
447 - Correct code so that FileSet MD5 is calculated for < and | filename
449 - Implement the Media record flag that indicates that the Volume does disk
451 - Implement VolAddr, which is used when Volume is addressed like a disk,
452 and form it from VolFile and VolBlock.
453 - Make multiple restore jobs for multiple media types specifying
454 the proper storage type.
455 - Implement MediaType keyword in bsr?
456 - Fix fast block rejection (stored/read_record.c:118). It passes a null
457 pointer (rec) to try_repositioning().
458 - Look at extracting Win data from BackupRead.
459 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
460 which would take precidence over the Catalog "JobRetention".
461 - Implement Label Format in Add and Label console commands.
462 - Possibly up network buffers to 65K. Put on variable.
463 - Put email tape request delays on one or more variables. User wants
464 to cancel the job after a certain time interval. Maximum Mount Wait?
465 - Job, Client, Device, Pool, or Volume?
466 Is it possible to make this a directive which is *optional* in multiple
467 resources, like Level? If so, I think I'd make it an optional directive
468 in Job, Client, and Pool, with precedence such that Job overrides Client
469 which in turn overrides Pool.
471 - New Storage specifications:
472 - Want to write to multiple storage devices simultaneously
473 - Want to write to multiple storage devices sequentially (in one job)
474 - Want to read/write simultaneously
475 - Key is MediaType -- it must match
477 Passed to SD as a sort of BSR record called Storage Specification
481 MediaType -> Next MediaType
483 Device -> Next Device
485 Allow multiple Storage specifications
493 Allow Multiple Pool specifications (note, Pool currently
495 Allow Multiple MediaType specifications in Dir conf
496 Allow Multiple Device specifications in Dir conf
497 Perhaps keep this in a single SSR
498 Tie a Volume to a specific device by using a MediaType that
499 is contained in only one device.
500 In SD allow Device to have Multiple MediaTypes
502 - Ideas from Jerry Scharf:
503 First let's point out some big pluses that bacula has for this
505 more importantly it's active. Thank you so much for that
506 even more important, it's not flaky
507 it has an open access catalog, opening many possibilities
508 it's pushing toward heterogeneous systems capability
510 Macintosh file client
511 macs are an interesting niche, but I fear a server is a rathole
512 working bare iron recovery for windows
513 the option for inc/diff backups not reset on fileset revision
514 a) use both change and inode update time against base time
515 b) do the full catalog check (expensive but accurate)
516 sizing guide (how much system is needed to back up N systems/files)
517 consultants on using bacula in building a disaster recovery system
519 or how to get at fancy things that one could do with bacula
520 logwatch code for bacula logs (or similar)
521 linux distro inclusion of bacula (brings good and bad, but necessary)
522 win2k/XP server capability (icky but you asked)
523 support for Oracle database ??
525 - Look at adding SQL server and Exchange support for Windows.
526 - Each DVD-RAM disk would be a volume, just like each tape is
527 a volume. It's a 4.7GB media with random access, but there's nothing about
528 it that I can see that makes it so different than a tape from bacula's
529 perspective. Why couldn't I back up to a bare floppy as a volume (ignoring
531 - Make dev->file and dev->block_num signed integers so that -1 can
532 be an invalid value which happens with BSR.
533 - Create VolAddr for disk files in place of VolFile and VolBlock. This
534 is needed to properly specify ranges.
535 - Add progress of files/bytes to SD and FD.
536 - Print warning message if FileId > 4 billion
537 - do a "messages" before the first prompt in Console
538 - Add a date and time stamp at the beginning of every line in the
539 Job report (Volker Sauer).
540 - Client does not show busy during Estimate command.
541 - Implement Console mtx commands.
542 - Implement a Mount Command and an Unmount Command where
543 the users could specify a system command to be performed
544 to do the mount, after which Bacula could attempt to
545 read the device. This is for Removeable media such as a CDROM.
546 - Most likely, this mount command would be invoked explicitly
547 by the user using the current Console "mount" and "unmount"
548 commands -- the Storage Daemon would do the right thing
549 depending on the exact nature of the device.
550 - As with tape drives, when Bacula wanted a new removable
551 disk mounted, it would unmount the old one, and send a message
552 to the user, who would then use "mount" as described above
553 once he had actually inserted the disk.
554 - Implement dump/print label to UA
555 - Spool to disk only when the tape is full, then when a tape is hung move
557 - bextract is sending everything to the log file ****FIXME****
558 - Allow multiple Storage specifications (or multiple names on
559 a single Storage specification) in the Job record. Thus a job
560 can be backed up to a number of storage devices.
561 - Implement some way for the File daemon to contact the Director
562 to start a job or pass its DHCP obtained IP number.
563 - Implement a query tape prompt/replace feature for a console
564 - Copy console @ code to gnome2-console
565 - Make AES the only encryption algorithm see
566 http://csrc.nist.gov/CryptoToolkit/aes/). It's
567 an officially adopted standard, has survived peer
568 review, and provides keys up to 256 bits.
569 - Take a careful look at SetACL http://setacl.sourceforge.net
570 - Take a careful look at Level for the estimate command, maybe make
571 it a command line option.
572 - Add Volume name to "I cannot write on this volume because"
573 - Make tree walk routines like cd, ls, ... more user friendly
574 by handling spaces better.
575 - Make sure that Bacula rechecks the tape after the 20 min wait.
576 - Set IO_NOWAIT on Bacula TCP/IP packets.
577 - Try doing a raw partition backup and restore by mounting a
580 Yes, it would allow to highly automatic the request for new tapes. If a
581 tape is empty, bacula reads the barcodes (native or simulated), and if
582 an unused tape is found, it runs the label command with all the
583 necessary parameters.
585 By the way can bacula automatically "move" an empty/purged volume say
586 in the "short" pool to the "long" pool if this pool runs out of volume
588 - What to do about "list files job=xxx".
589 - Make Dmsg look at global before calling subroutine.
590 - Get and test MySQL 4.0
591 - Look at how fuser works and /proc/PID/fd that is how Nic found the
592 file descriptor leak in Bacula.
593 - Implement WrapCounters in Counters.
594 - Add heartbeat from FD to SD if hb interval expires.
595 - Can we dynamically change FileSets?
596 - If pool specified to label command and Label Format is specified,
597 automatically generate the Volume name.
598 - Why can't SQL do the filename sort for restore?
599 - Look into Microsoft Volume Shadowcopy Service VSS for backing
600 up system state components (Active Directory, System Volume, ...)
601 - Add ExhautiveRestoreSearch
602 - Look at the possibility of loading only the necessary
603 data into the restore tree (i.e. do it one directory at a
604 time as the user walks through the tree).
605 - Possibly use the hash code if the user selects all for a restore command.
606 - Fix "restore all" to bypass building the tree.
607 - Prohibit backing up archive device (findlib/find_one.c:128)
608 - Implement Release Device in the Job resource to unmount a drive.
609 - Implement Acquire Device in the Job resource to mount a drive,
610 be sure this works with admin jobs so that the user can get
611 prompted to insert the correct tape. Possibly some way to say to
612 run the job but don't save the files.
613 - Make things like list where a file is saved case independent for
616 - Use autochanger to handle multiple devices.
617 - Add SuSE install doc to list.
618 - Check and rechedk "Invalid block number"
619 - User wants to NOT backup up certain big files (email files).
620 - Maybe remove multiple simultaneous devices code in SD.
621 - On Windows with very long path names, it may be impossible to create
622 a file (and thus restore it) because the total length is too long.
623 We must cd into the directory then create the file without the
625 - Implement a Recycle command
626 - Add client name to cram-md5 challenge so Director can immediately
627 verify if it is the correct client.
628 - Audit all UA commands to ensure that we always prompt where possible.
629 - Make bootstrap filename unique.
630 - Test a second language e.g. french.
631 - Start working on Base jobs.
632 - Implement UnsavedFiles DB record.
633 - Implement argc/argv for daemon command line scanning using table driven
635 - From Phil Stracchino:
636 It would probably be a per-client option, and would be called
637 something like, say, "Automatically purge obsoleted jobs". What it
638 would do is, when you successfully complete a Differential backup of a
639 client, it would automatically purge all Incremental backups for that
640 client that are rendered redundant by that Differential. Likewise,
641 when a Full backup on a client completed, it would automatically purge
642 all Differential and Incremental jobs obsoleted by that Full backup.
643 This would let people minimize the number of tapes they're keeping on
644 hand without having to master the art of retention times.
645 - Implement a M_SECURITY message class.
646 - When doing a Backup send all attributes back to the Director, who
647 would then figure out what files have been deleted.
648 - Currently in mount.c:236 the SD simply creates a Volume. It should have
649 explicit permission to do so. It should also mark the tape in error
650 if there is an error.
651 - SD Bytes Read is wrong.
652 - Investigate doing RAW backup of Win32 partition.
653 - Cancel waiting for Client connect in SD if FD goes away.
655 - Implement timeout in response() when it should come quickly.
656 - Implement console @echo command.
657 - Implement a Slot priority (loaded/not loaded).
658 - Implement "vacation" Incremental only saves.
659 - Implement single pane restore (much like the Gftp panes).
660 - Implement Automatic Mount even in operator wait.
661 - Implement create "FileSet"?
662 - Implement restore "current system", but take all files without
663 doing selection tree -- so that jobs without File records can
665 - Add prefixlinks to where or not where absolute links to FD.
666 - Issue message to mount a new tape before the rewind.
667 - Simplified client job initiation for portables.
668 - If SD cannot open a drive, make it periodically retry.
669 - Add more of the config info to the tape label.
671 - If tape is marked read-only, then try opening it read-only rather than
672 failing, and remember that it cannot be written.
673 - Refine SD waiting output:
674 Device is being positioned
675 > Device is being positioned for append
676 > Device is being positioned to file x
678 - Figure out some way to estimate output size and to avoid splitting
679 a backup across two Volumes -- this could be useful for writing CDROMs
680 where you really prefer not to have it split -- not serious.
681 - Have SD compute MD5 or SHA1 and compare to what FD computes.
682 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
683 actual data on the Volume and compare it.
684 - Implement Bacula plugins -- design API
685 - Make bcopy read through bad tape records.
686 - Program files (i.e. execute a program to read/write files).
687 Pass read date of last backup, size of file last time.
688 - Add Signature type to File DB record.
689 - CD into subdirectory when open()ing files for backup to
690 speed up things. Test with testfind().
691 - Priority job to go to top of list.
692 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
693 - Implement some way for the Console to dynamically create a job.
694 - Restore to a particular time -- e.g. before date, after date.
695 - Solaris -I on tar for include list
696 - Need a verbose mode in restore, perhaps to bsr.
697 - bscan without -v is too quiet -- perhaps show jobs.
698 - Add code to reject whole blocks if not wanted on restore.
699 - Check if we can increase Bacula FD priorty in Win2000
700 - Make sure the MaxVolFiles is fully implemented in SD
701 - Check if both CatalogFiles and UseCatalog are set to SD.
702 - Figure out how to do a bare metal Windows restore
703 - Possibly add email to Watchdog if drive is unmounted too
704 long and a job is waiting on the drive.
705 - After unmount, if restore job started, ask to mount.
706 - Convert all %x substitution variables, which are hard to remember
707 and read to %(variable-name). Idea from TMDA.
708 - Remove NextId for SQLite. Optimize.
709 - Move all SQL statements into a single location.
710 - Add UA rc and history files.
711 - put termcap (used by console) in ./configure and
712 allow -with-termcap-dir.
713 - Fix Autoprune for Volumes to respect need for full save.

722 - Minimum Message Interval
723 - Maximum Message Interval
724 - Send Operator message when cannot read tape label.
725 - Verify level=Volume (scan only), level=Data (compare of data to file).
726 Verify level=Catalog, level=InitCatalog
728 - Add keyword search to show command in Console.
729 - Events : tape has more than xxx bytes.
730 - Complete code in Bacula Resources -- this will permit
731 reading a new config file at any time.
732 - Handle ctl-c in Console
733 - Implement script driven addition of File daemon to config files.
734 - Think about how to make Bacula work better with File (non-tape) archives.
735 - Write Unix emulator for Windows.
736 - Put memory utilization in Status output of each daemon
737 if full status requested or if some level of debug on.
738 - Make database type selectable by .conf files i.e. at runtime

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

862 > mechanism described below would probably make it very easy.
864 This is the goal. In the first step (before events), you simply
866 the Migration to tape later.
868 2. Base jobs: In ADSM, each copy of each stored file is tracked in
869 the database. Once a file (unique by path and metadata such as dates,
870 size, ownership, etc.) is in a copy pool, no more copies are made. In
871 other words, when you start ADSM, it begins like your concept of a
872 base job. After that it is in the "incremental" mode. You can
873 configure the number of "generations" of files to be retained, plus a
874 retention date after which even old generations are purged. The
875 database tracks the contents of media and projects the percentage of
876 each volume that is valid. When the valid content of a volume drops
877 below a configured percentage, the valid data are migrated to another
878 volume and the old volume is marked as empty. Note, this requires
879 ADSM to have an idea of the contents of a client, i.e. marking the
880 database when an existing file was deleted, but this would solve your
881 issue of restoring a client without restoring deleted files.
883 This is pretty far from what bacula now does, but if you are going to
884 rip things up for Base jobs,.....
885 Also, the benefits of this are huge for very large shops, especially
886 with media robots, but are a pain for shops with manual media
890 > Base jobs sound pretty useful, but I'm not dying for them.
892 Nobody is dying for them, but when you see what it does, you will die
895 3. Restoring deleted files: Since I think my comments in (2) above
896 have low probability of implementation, I'll also suggest that you
897 could approach the issue of deleted files by a mechanism of having the
898 fd report to the dir, a list of all files on the client for every
899 backup job. The dir could note in the database entry for each file
900 the date that the file was seen. Then if a restore as of date X takes
901 place, only files that exist from before X until after X would be
902 restored. Probably the major cost here is the extra date container in
903 each row of the files table.
905 Thanks for "listening". I hope some of this helps. If you want to
906 contact me, please send me an email - I read some but not all of the
907 mailing list traffic and might miss a reply there.
909 Please accept my compliments for bacula. It is doing a great job for
910 me!! I sympathize with you in the need to wrestle with excelence in
911 execution vs. excelence in feature inclusion.
916 ==============================
919 - Design at hierarchial storage for Bacula. Migration and Clone.
920 - Implement FSM (File System Modules).
921 - Audit M_ error codes to ensure they are correct and consistent.
922 - Add variable break characters to lex analyzer.
923 Either a bit mask or a string of chars so that
924 the caller can change the break characters.
925 - Make a single T_BREAK to replace T_COMMA, etc.
926 - Ensure that File daemon and Storage daemon can
927 continue a save if the Director goes down (this
928 is NOT currently the case). Must detect socket error,
929 buffer messages for later.
930 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
931 - Add ability to backup to two Storage devices (two SD sessions) at
932 the same time -- e.g. onsite, offsite.
933 - Add the ability to consolidate old backup sets (basically do a restore
934 to tape and appropriately update the catalog). Compress Volume sets.
935 Might need to spool via file is only one drive is available.
936 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
937 someway to do so with every volume that has less than x% valid
941 Migration: Move a backup from one Volume to another
942 Clone: Copy a backup -- two Volumes
944 Bacula Migration is based on Jobs (apparently Networker is file by file).
946 Migration triggered by:
950 Highwater mark (keep total size)
955 ======================================================
957 It is somewhat like a Full save becomes an incremental since
958 the Base job (or jobs) plus other non-base files.
960 - A Base backup is same as Full backup, just different type.
961 - New BaseFiles table that contains:
963 BaseJobId - Base JobId referenced for this FileId (needed ???)
964 JobId - JobId currently running
965 FileId - File not backed up, exists in Base Job
966 FileIndex - FileIndex from Base Job.
967 i.e. for each base file that exists but is not saved because
968 it has not changed, the File daemon sends the JobId, BaseId,
969 FileId, FileIndex back to the Director who creates the DB entry.
970 - To initiate a Base save, the Director sends the FD
971 the FileId, and full filename for each file in the Base.
972 - When the FD finds a Base file, he requests the Director to
973 send him the full File entry (stat packet plus MD5), or
974 conversely, the FD sends it to the Director and the Director
975 says yes or no. This can be quite rapid if the FileId is kept
976 by the FD for each Base Filename.
977 - It is probably better to have the comparison done by the FD
978 despite the fact that the File entry must be sent across the
980 - An alternative would be to send the FD the whole File entry
981 from the start. The disadvantage is that it requires a lot of
982 space. The advantage is that it requires less communications
984 - The Job record must be updated to indicate that one or more
986 - At end of Job, FD returns:
987 1. Count of base files/bytes not written to tape (i.e. matches)
988 2. Count of base file that were saved i.e. had changed.
989 - No tape record would be written for a Base file that matches, in the
990 same way that no tape record is written for Incremental jobs where
991 the file is not saved because it is unchanged.
992 - On a restore, all the Base file records must explicitly be
993 found from the BaseFile tape. I.e. for each Full save that is marked
994 to have one or more Base Jobs, search the BaseFile for all occurrences
996 - An optimization might be to make the BaseFile have:
1002 This would avoid the need to explicitly fetch each File record for
1003 the Base job. The Base Job record will be fetched to get the
1004 VolSessionId and VolSessionTime.
1005 =========================================================
1008 ==========================================================
1010 For each Incremental job that is run, there may be files that
1011 were found but not saved because they were locked (this applies
1012 only to Windows). Such a system could send back to the Director
1013 a list of Unsaved files.
1015 - New UnSavedFiles table that contains:
1019 - Then in the next Incremental job, the list of Unsaved Files will be
1020 feed to the FD, who will ensure that they are explicitly chosen even
1021 if standard date/time check would not have selected them.
1022 =============================================================
1025 Done: (see kernsdone for more)
1028 - John's Full save failed with 1.32c FD and 1.31 Dir no FD status,
1029 and no error message.
1030 - Add fd and st as Console keywords.
1031 - Recycling volume with a Slot requires an operator intervention:
1032 rufus-dir: Start Backup JobId 18, Job=kernsave.2003-11-01_21.23.52
1033 rufus-dir: Pruned 1 Job on Volume Vol01 from catalog.
1034 rufus-dir: There are no Jobs associated with Volume Vol01. Marking it purged.
1035 rufus-dir: Recycled volume "Vol01"
1036 rufus-sd: Please mount Volume "Vol01" on Storage Device "DDS-4" for Job kernsave.2003-11-01_21.23.52
1037 Use "mount" command to release Job.
1038 - Implement Dan's bacula script (email of 26 Oct).
1039 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
1040 - Edit the Client/Storage name into authentication failure messages.
1041 - Fix packet too big problem. This is most likely a Windows TCP stack
1043 - Implement ClientRunBeforeJob and ClientRunAfterJob.
1044 - Implement forward spacing block/file: position_device(bsr) --
1045 just before read_block_from_device();

1085 (just to verify it remembers where it came from, however it can be
1086 overrriden with mtx unload {slotnumber} to go to any storage slot.)
1088 There needs to be a table of drive # to devices somewhere - If there are
1089 multiple changers or drives there may not be a 1:1 correspondance between
1090 changer drive number and system device name - and depending on the way the
1091 drives are hooked up to scsi busses, they may not be linearly numbered
1092 from an offset point either.something like
1094 Autochanger drives = 2
1095 Autochanger drive 0 = /dev/nst1
1096 Autochanger drive 1 = /dev/nst2
1097 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1098 times, not just for multidrive changers. For a 1 drive changer, that's
1104 MTX's manpage (1.2.15):
1105 unload [<slotnum>] [ <drivenum> ]
1106 Unloads media from drive <drivenum> into slot
1107 <slotnum>. If <drivenum> is omitted, defaults to
1108 drive 0 (as do all commands). If <slotnum> is
1109 omitted, defaults to the slot that the drive was
1110 loaded from. Note that there's currently no way
1111 to say 'unload drive 1's media to the slot it
1112 came from', other than to explicitly use that
1113 slot number as the destination.AB

1153 From: Karl Cunningham <karlc@keckec.com>
1155 My backups are only to hard disk these days, in removable bays. This is my
1156 idea of how a backup to hard disk would work more smoothly. Some of these
1157 things Bacula does already, but I mention them for completeness. If others
1158 have better ways to do this, I'd like to hear about it.
1160 1. Accommodate several disks, rotated similar to how tapes are. Identified
1161 by partition volume ID or perhaps by the name of a subdirectory.
1162 2. Abort & notify the admin if the wrong disk is in the bay.
1163 3. Write backups to different subdirectories for each machine to be backed
1165 4. Volumes (files) get created as needed in the proper subdirectory, one
1167 5. When a disk is recycled, remove or zero all old backup files. This is
1168 important as the disk being recycled may be close to full. This may be
1169 better done manually since the backup files for many machines may be
1170 scattered in many subdirectories.
1175 - Save mount point for directories not traversed with onefs=yes.
1176 - Add seconds to start and end times in the Job report output.
1177 - if 2 concurrent backups are attempted on the same tape
1178 drive (autoloader) into different tape pools, one of them will exit
1179 fatally instead of halting until the drive is idle
1180 - Update StartTime if job held in Job Queue.
1181 - Look at www.nu2.nu/pebuilder as a helper for full windows
1182 bare metal restore. (done by Scott)
1183 - Fix orphanned buffers:
1184 Orphaned buffer: 24 bytes allocated at line 808 of rufus-dir job.c
1185 Orphaned buffer: 40 bytes allocated at line 45 of rufus-dir alist.c
1186 - Implement Preben's suggestion to add
1187 File System Types = ext2, ext3
1188 to FileSets, thus simplifying backup of *all* local partitions.
