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 - Create a new GUI chapter explaining all the GUI programs.
35 - Tell the "restore" user when browsing is no longer possible.
36 - Add disk seeking on restore.
37 - Cancel command should include JobId in list of Jobs.
38 - Require restore via the restore command or make a restore Job

41 - Make bootstrap file handle multiple MediaTypes (SD)
42 - Add offline command to Bacula console.
43 - Add performance testing hooks
44 - Add Python writable variable for changing the Priority.
45 - Document that Bootstrap files can be written with cataloging
47 - Look at adding full Volume and Pool information to a Volume
48 label so that bscan can get *all* the info.
49 - Scratch Pool where the volumes can be re-assigned to any Pool.
50 - Upgrade to MySQL 4.1.1 See:
51 http://dev.mysql.com/doc/mysql/en/Server_SQL_mode.html
53 Enter MediaId or Volume name: 32
54 Enter new Volume name: DLT-20Dec04
55 Automatically selected Pool: Default
56 Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...
57 Sending relabel command from "DLT-28Jun03" to "DLT-20Dec04" ...
58 block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
59 Error writing final EOF to tape. This tape may not be readable.
60 dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
61 askdir.c:219 NULL Volume name. This shouldn't happen!!!

64 Label command failed for Volume DLT-20Dec04.
65 Do not forget to mount the drive!!!
66 - Bug: if a job is manually scheduled to run later, it does not appear
67 in any status report and cannot be cancelled.
69 Regression tests (Jo):
70 - Add Pool/Storage override regression test.
71 - Add delete JobId to regression.
72 - Add a regression test for dbcheck.
73 - New test to add bscan to four-concurrent-jobs regression,
74 i.e. after the four-concurrent jobs zap the
75 database as is done in the bscan-test, then use bscan to
76 restore the database, do a restore and compare with the
78 - Add restore of specific JobId to regression (item 3
79 on the restore prompt)
80 - Add IPv6 to regression
81 - Add database test to regression. Test each function like delete,
84 - AntiVir can slow down backups on Win32 systems.
85 - Win32 systems with FAT32 can be much slower than NTFS for
86 more than 1000 files per directory.
91 - Media Type (read/write)
94 - Media Type (read/write)
102 - Media Type (read/write)
107 - Migration Time (time after which data migrated to next Pool)
108 - Maximum Devices (that can use Pool simultaneously)
111 - List of Devices/Device Groups/Storage groups
112 (i.e. physical restraint)
115 - Migration Time (time after which data migrated to next Pool)
116 - Maximum Devices (that can use Pool simultaneously)
121 - Can one write tapes faster with 8192 byte block sizes?
122 - Specify a single directory to restore.
123 - Implement Maximum Job Spool Size
124 - Document security problems with the same password for everyone in
125 rpm and Win32 releases.
126 - Browse generations of files.
127 - I've seen an error when my catalog's File table fills up. I
128 then have to recreate the File table with a larger maximum row
129 size. Relevant information is at
130 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
131 "Installing and Configuring MySQL" chapter should talk a bit
132 about this potential problem, and recommend a solution.
133 - For Solaris must use POSIX awk.
134 - Want speed of writing to tape while despooling.
135 - Supported autochanger:
143 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
144 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
145 - Add regex from http://www.pcre.org to Bacula for Win32.
146 - Use only shell tools no make in CDROM package.
147 - Document PostgreSQL performance problems bug 131.
149 - Document that ChangerDevice is used for Alert command.
150 - Include within include does it work?
151 - Implement a Pool of type Cleaning?
152 - Implement VolReadTime and VolWriteTime in SD
153 - Modify Backing up Your Database to include a bootstrap file.
154 - Think about making certain database errors fatal.
155 - Look at correcting the time jump in the scheduler for daylight
156 savings time changes.
157 - Add a "real" timer to network connections.
158 - Write non-optimized bsrs from the JobMedia and Media records,
159 even after Files are pruned.
160 - Promote to Full = Time period
161 - Despool attributes simultaneously with data in a separate
162 thread, rejoined at end of data spooling.
163 - Implement Files/Bytes,... stats for restore job.
164 - Implement Total Bytes Written, ... for restore job.
165 - Check dates entered by user for correctness (month/day/... ranges)
166 - Compress restore Volume listing by date and first file.
167 - Look at patches/bacula_db.b2z postgresql that loops during restore.
169 - Perhaps add read/write programs and/or plugins to FileSets.
170 - How to handle backing up portables ...
171 - Add some sort of guaranteed Interval for upgrading jobs.
172 - Can we write the state file after every job terminates? On Win32
173 the system crashes and the state file is not updated.
176 Documentation to do: (any release a little bit at a time)
177 - Doc to do unmount before removing magazine.
178 - Alternative to static linking "ldd prog" save all binaries listed,
179 restore them and point LD_LIBRARY_PATH to them.
180 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
181 - Document query file format.
182 - Add more documentation for bsr files.
183 - Document problems with Verify and pruning.
184 - Document how to use multiple databases.
185 - VXA drives have a "cleaning required"
186 indicator, but Exabyte recommends preventive cleaning after every 75
189 In this context, it should be noted that Exabyte has a command-line
190 vxatool utility available for free download. (The current version is
191 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
192 test the drive, unload tapes, change drive settings, flash new firmware,
194 Of particular interest in this context is that vxatool <device> -i will
195 report, among other details, the time since last cleaning in tape motion
196 minutes. This information can be retrieved (and settings changed, for
197 that matter) through the generic-SCSI device even when Bacula has the
198 regular tape device locked. (Needless to say, I don't recommend
199 changing tape settings while a job is running.)
200 - Lookup HP cleaning recommendations.
201 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
202 - Document doing table repair
205 Testing to do: (painful)
208 For 1.37 Testing/Documentation:
209 - Add bandwidth limiting.
210 - Add acks every once and a while from the SD to keep
211 the line from timing out.
212 - When an error in input occurs and conio beeps, you can back
213 up through the prompt.
214 - Detect fixed tape block mode during positioning by looking at
215 block numbers in btape "test". Possibly adjust in Bacula.
216 - Fix list volumes to output volume retention in some other
217 units, perhaps via a directive.
218 - If opening a tape in read/write mode fails attempt to open
219 it in read-only mode, and mark the tape for read only.
220 - Add a read-only mode to the mount option.
221 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
222 with multiple priorities.
223 - If you use restore replace=never, the directory attributes for
224 non-existent directories will not be restored properly.
226 - see lzma401.zip in others directory for new compression
228 - Minimal autochanger handling in Bacula and in btape.
229 - Look into how tar does not save sockets and the possiblity of
230 not saving them in Bacula (Martin Simmons reported this).
231 - Fix restore jobs so that multiple jobs can run if they
232 are not using the same tape(s).
233 - Allow the user to select JobType for manual pruning/purging.
234 - bscan does not put first of two volumes back with all info in
236 - Implement the FreeBSD nodump flag in chflags.
237 - Figure out how to make named console messages go only to that
238 console and to the non-restricted console (new console class?).
239 - Make restricted console prompt for password if *ask* is set or
240 perhaps if password is undefined.
241 - Implement "from ISO-date/time every x hours/days/weeks/months" in
246 MA = (last_MA * 3 + rate) / 4
247 rate = (bytes - last_bytes) / (runtime - last_runtime)
249 ==== from Marc Schoechlin
250 - the help-command should be more verbose
251 (it should explain the paramters of the different
253 -> it´s time-comsuming to consult the manual anytime
254 you need a special parameter
255 -> maybe it´s more easy to maintain this, if the
256 descriptions of that commands are outsourced to
258 - the cd-command should allow complete paths
259 i.e. cd /foo/bar/foo/bar
260 -> if a customer mails me the path to a certain file,
261 it´s faster to enter the specified directory
262 - if the password is not configured in bconsole.conf
263 you should be asked for it.
264 -> sometimes you like to do restore on a customer-machine
265 which shouldn´t know the password for bacula.
266 -> adding the password to the file favours admins
267 to forget to remove the password after usage
269 the protection of that file is less important
270 - long-listed-output of commands should be scrollable
271 like the unix more/less-command does
272 -> if someone runs 200 and more machines, the lists could
273 be a little long and complex
274 - command-output should be shown column by column
275 to reduce scrolling and to increase clarity
277 - lsmark should list the selected files with full
279 - wildcards for selecting and file and directories would be nice
280 - any actions should be interuptable with STRG+C
281 - command-expansion would be pretty cool
283 - Compaction of Disk space by "migrating" Volumes that have pruned
284 Jobs (what criteria? size, #jobs, time).
285 - Add prune all command
286 - Document fact that purge can destroy a part of a restore by purging
287 one volume while others remain valid -- perhaps mark Jobs.
288 - Add multiple-media-types.txt
289 - look at mxt-changer.html
290 - Make ? do a help command (no return needed).
291 - Implement restore directory.
292 - Document streams and how to implement them.
293 - Try not to re-backup a file if a new hard link is added.
294 - Add feature to backup hard links only, but not the data.
295 - Fix stream handling to be simpler.
296 - Add Priority and Bootstrap to Run a Job.
297 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
299 - Remove View FileSet button from Run a Job dialog.
300 - Handle prompt for restore job at end of Restore command.
301 - Add display of total selected files to Restore window.
302 - Add tree pane to left of window.
303 - Add progress meter.
304 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
305 - Document writing to a CD/DVD with Bacula.
306 - Add a "base" package to the window installer for pthreadsVCE.dll
307 which is needed by all packages.
308 - Add message to user to check for fixed block size when the forward
309 space test fails in btape.
310 - When unmarking a directory check if all files below are unmarked and
311 then remove the + flag -- in the restore tree.
312 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
313 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
314 - Revisit the question of multiple Volumes (disk) on a single device.
315 - Add a block copy option to bcopy.
316 - Investigate adding Mac Resource Forks.
317 - Finish work on Gnome restore GUI.
318 - Fix "llist jobid=xx" where no fileset or client exists.
320 it seems to be complaining about 12:00pm which should be a valid 12
321 hour time. I changed the time to 11:59am and everything works fine.
322 Also 12:00am works fine. 0:00pm also works (which I don't think
323 should). None of the values 12:00pm - 12:59pm work for that matter.
324 - Add level to estimate command.
325 - For each job type (Admin, Restore, ...) require only the really necessary
327 - Fix option 2 of restore -- list where file is backed up -- require Client,
328 then list last 20 backups.
329 - Pass Director resource name as an option to the Console.
330 - Add a "batch" mode to the Console (no unsolicited queries, ...).
331 - Add a .list all files in the restore tree (probably also a list all files)
332 Do both a long and short form.
333 - Allow browsing the catalog to see all versions of a file (with
334 stat data on each file).
335 - Restore attributes of directory if replace=never set but directory
337 - Use SHA1 on authentication if possible.
338 - See comtest-xxx.zip for Windows code to talk to USB.
339 - Add Events and Perl scripting.
340 - Add John's appended files:
341 Appended = { /files/server/logs/http/*log }
342 and such files would be treated as follows.On a FULL backup, they would
343 be backed up like any other file.On an INCREMENTAL backup, where a
344 previous INCREMENTAL or FULL was already in thecatalogue and the length
345 of the file wasgreater than the length of the last backup, only thedata
346 added since the last backup will be dumped.On an INCREMENTAL backup, if
347 the length of the file is less than thelength of the file with the same
348 name last backed up, the completefile is dumped.On Windows systems, with
349 creation date of files, we can be evensmarter about this and not count
350 entirely upon the length.On a restore, the full and all incrementals
351 since it will beapplied in sequence to restore the file.
352 - Allow for optional cancelling of SD and FD in case DIR
353 gets a fatal error. Requested by Jesse Guardiani <jesse@wingnet.net>
354 - Add "limit=n" for "list jobs"
355 - Check new HAVE_WIN32 open bits.
356 - Check if the tape has moved before writing.
357 - Handling removable disks -- see below:
358 - Keep track of tape use time, and report when cleaning is necessary.
359 - Add FromClient and ToClient keywords on restore command (or
360 BackupClient RestoreClient).
361 - Implement a JobSet, which groups any number of jobs. If the
362 JobSet is started, all the jobs are started together.
363 Allow Pool, Level, and Schedule overrides.
364 - Enhance cancel to timeout BSOCK packets after a specific delay.
365 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
366 ua_status.!!! Thanks to Alan Brown for this tip.
367 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
368 correctly for multiple simultaneous jobs.
369 - Correct code so that FileSet MD5 is calculated for < and | filename
371 - Implement the Media record flag that indicates that the Volume does disk
373 - Implement VolAddr, which is used when Volume is addressed like a disk,
374 and form it from VolFile and VolBlock.
375 - Make multiple restore jobs for multiple media types specifying
376 the proper storage type.
377 - Implement MediaType keyword in bsr?
378 - Fix fast block rejection (stored/read_record.c:118). It passes a null
379 pointer (rec) to try_repositioning().
380 - Look at extracting Win data from BackupRead.
381 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
382 which would take precidence over the Catalog "JobRetention".
383 - Implement Label Format in Add and Label console commands.
384 - Possibly up network buffers to 65K. Put on variable.
385 - Put email tape request delays on one or more variables. User wants
386 to cancel the job after a certain time interval. Maximum Mount Wait?
387 - Job, Client, Device, Pool, or Volume?
388 Is it possible to make this a directive which is *optional* in multiple
389 resources, like Level? If so, I think I'd make it an optional directive
390 in Job, Client, and Pool, with precedence such that Job overrides Client
391 which in turn overrides Pool.
393 - New Storage specifications:
394 - Want to write to multiple storage devices simultaneously
395 - Want to write to multiple storage devices sequentially (in one job)
396 - Want to read/write simultaneously
397 - Key is MediaType -- it must match
399 Passed to SD as a sort of BSR record called Storage Specification
403 MediaType -> Next MediaType
405 Device -> Next Device
407 Allow multiple Storage specifications
415 Allow Multiple Pool specifications (note, Pool currently
417 Allow Multiple MediaType specifications in Dir conf
418 Allow Multiple Device specifications in Dir conf
419 Perhaps keep this in a single SSR
420 Tie a Volume to a specific device by using a MediaType that
421 is contained in only one device.
422 In SD allow Device to have Multiple MediaTypes
424 - Ideas from Jerry Scharf:
425 First let's point out some big pluses that bacula has for this
427 more importantly it's active. Thank you so much for that
428 even more important, it's not flaky
429 it has an open access catalog, opening many possibilities
430 it's pushing toward heterogeneous systems capability
432 Macintosh file client
433 macs are an interesting niche, but I fear a server is a rathole
434 working bare iron recovery for windows
435 the option for inc/diff backups not reset on fileset revision
436 a) use both change and inode update time against base time
437 b) do the full catalog check (expensive but accurate)
438 sizing guide (how much system is needed to back up N systems/files)
439 consultants on using bacula in building a disaster recovery system
441 or how to get at fancy things that one could do with bacula
442 logwatch code for bacula logs (or similar)
443 linux distro inclusion of bacula (brings good and bad, but necessary)
444 win2k/XP server capability (icky but you asked)
445 support for Oracle database ??
447 - Look at adding SQL server and Exchange support for Windows.
448 - Each DVD-RAM disk would be a volume, just like each tape is
449 a volume. It's a 4.7GB media with random access, but there's nothing about
450 it that I can see that makes it so different than a tape from bacula's
451 perspective. Why couldn't I back up to a bare floppy as a volume (ignoring
453 - Make dev->file and dev->block_num signed integers so that -1 can
454 be an invalid value which happens with BSR.
455 - Create VolAddr for disk files in place of VolFile and VolBlock. This
456 is needed to properly specify ranges.
457 - Add progress of files/bytes to SD and FD.
458 - Print warning message if FileId > 4 billion
459 - do a "messages" before the first prompt in Console
460 - Add a date and time stamp at the beginning of every line in the
461 Job report (Volker Sauer).
462 - Client does not show busy during Estimate command.
463 - Implement Console mtx commands.
464 - Implement a Mount Command and an Unmount Command where
465 the users could specify a system command to be performed
466 to do the mount, after which Bacula could attempt to
467 read the device. This is for Removeable media such as a CDROM.
468 - Most likely, this mount command would be invoked explicitly
469 by the user using the current Console "mount" and "unmount"
470 commands -- the Storage Daemon would do the right thing
471 depending on the exact nature of the device.
472 - As with tape drives, when Bacula wanted a new removable
473 disk mounted, it would unmount the old one, and send a message
474 to the user, who would then use "mount" as described above
475 once he had actually inserted the disk.
476 - Implement dump/print label to UA
477 - Spool to disk only when the tape is full, then when a tape is hung move
479 - bextract is sending everything to the log file ****FIXME****
480 - Allow multiple Storage specifications (or multiple names on
481 a single Storage specification) in the Job record. Thus a job
482 can be backed up to a number of storage devices.
483 - Implement some way for the File daemon to contact the Director
484 to start a job or pass its DHCP obtained IP number.
485 - Implement a query tape prompt/replace feature for a console
486 - Copy console @ code to gnome2-console
487 - Make AES the only encryption algorithm see
488 http://csrc.nist.gov/CryptoToolkit/aes/). It's
489 an officially adopted standard, has survived peer
490 review, and provides keys up to 256 bits.
491 - Take a careful look at SetACL http://setacl.sourceforge.net
492 - Take a careful look at Level for the estimate command, maybe make
493 it a command line option.
494 - Add Volume name to "I cannot write on this volume because"
495 - Make tree walk routines like cd, ls, ... more user friendly
496 by handling spaces better.
497 - Make sure that Bacula rechecks the tape after the 20 min wait.
498 - Set IO_NOWAIT on Bacula TCP/IP packets.
499 - Try doing a raw partition backup and restore by mounting a
502 Yes, it would allow to highly automatic the request for new tapes. If a
503 tape is empty, bacula reads the barcodes (native or simulated), and if
504 an unused tape is found, it runs the label command with all the
505 necessary parameters.
507 By the way can bacula automatically "move" an empty/purged volume say
508 in the "short" pool to the "long" pool if this pool runs out of volume
510 - What to do about "list files job=xxx".
511 - Make Dmsg look at global before calling subroutine.
512 - Get and test MySQL 4.0
513 - Look at how fuser works and /proc/PID/fd that is how Nic found the
514 file descriptor leak in Bacula.
515 - Implement WrapCounters in Counters.
516 - Add heartbeat from FD to SD if hb interval expires.
517 - Can we dynamically change FileSets?
518 - If pool specified to label command and Label Format is specified,
519 automatically generate the Volume name.
520 - Why can't SQL do the filename sort for restore?
521 - Look into Microsoft Volume Shadowcopy Service VSS for backing
522 up system state components (Active Directory, System Volume, ...)
523 - Add ExhautiveRestoreSearch
524 - Look at the possibility of loading only the necessary
525 data into the restore tree (i.e. do it one directory at a
526 time as the user walks through the tree).
527 - Possibly use the hash code if the user selects all for a restore command.
528 - Fix "restore all" to bypass building the tree.
529 - Prohibit backing up archive device (findlib/find_one.c:128)
530 - Implement Release Device in the Job resource to unmount a drive.
531 - Implement Acquire Device in the Job resource to mount a drive,
532 be sure this works with admin jobs so that the user can get
533 prompted to insert the correct tape. Possibly some way to say to
534 run the job but don't save the files.
535 - Make things like list where a file is saved case independent for
538 - Use autochanger to handle multiple devices.
539 - Add SuSE install doc to list.
540 - Check and rechedk "Invalid block number"
541 - User wants to NOT backup up certain big files (email files).
542 - Maybe remove multiple simultaneous devices code in SD.
543 - On Windows with very long path names, it may be impossible to create
544 a file (and thus restore it) because the total length is too long.
545 We must cd into the directory then create the file without the
547 - Implement a Recycle command
548 - Add client name to cram-md5 challenge so Director can immediately
549 verify if it is the correct client.
550 - Audit all UA commands to ensure that we always prompt where possible.
551 - Make bootstrap filename unique.
552 - Test a second language e.g. french.
553 - Start working on Base jobs.
554 - Implement UnsavedFiles DB record.
555 - Implement argc/argv for daemon command line scanning using table driven
557 - From Phil Stracchino:
558 It would probably be a per-client option, and would be called
559 something like, say, "Automatically purge obsoleted jobs". What it
560 would do is, when you successfully complete a Differential backup of a
561 client, it would automatically purge all Incremental backups for that
562 client that are rendered redundant by that Differential. Likewise,
563 when a Full backup on a client completed, it would automatically purge
564 all Differential and Incremental jobs obsoleted by that Full backup.
565 This would let people minimize the number of tapes they're keeping on
566 hand without having to master the art of retention times.
567 - Implement a M_SECURITY message class.
568 - When doing a Backup send all attributes back to the Director, who
569 would then figure out what files have been deleted.
570 - Currently in mount.c:236 the SD simply creates a Volume. It should have
571 explicit permission to do so. It should also mark the tape in error
572 if there is an error.
573 - SD Bytes Read is wrong.
574 - Investigate doing RAW backup of Win32 partition.

737 owner, group, user, quotas
738 - Store info on each file system type (probably in the job header on tape.
739 This could be the output of df; or perhaps some sort of /etc/mtab record.
741 ========= ideas ===============
742 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
743 To: <kern@sibbald.com>
744 Subject: RE: [Bacula-users] future large programming jobs
745 Date: Thu, 26 Feb 2004 11:34:54 -0600
747 I noticed the subject thread and thought I would offer the following
748 merely as sources of ideas, i.e. something to think about, not even as
749 strong as a request. In my former life (before retiring) I often
750 dealt with backups and storage management issues/products as a
751 developer and as a consultant. I am currently migrating my personal
752 network from amanda to bacula specifically because of the ability to
753 cross media boundaries during storing backups.
754 Are you familiar with the commercial product called ADSM (I think IBM
755 now sells it under the Tivoli label)? It has a couple of interesting
756 ideas that may apply to the following topics.
758 1. Migration: Consider that when you need to restore a system, there
759 may be pressure to hurry. If all the information for a single client
760 can eventually end up on the same media (and in chronological order),
761 the restore is facillitated by not having to search past information
762 from other clients. ADSM has the concept of "client affinity" that
763 may be associated with it's storage pools. It seems to me that this
764 concept (as an optional feature) might fit in your architecture for
767 ADSM also has the concept of defining one or more storage pools as
768 "copy pools" (almost mirrors, but only in the sense of contents).
769 These pools provide the ability to have duplicte data stored both
770 onsite and offsite. The copy process can be scheduled to be handled
771 by their storage manager during periods when there is no backup
772 activity. Again, the migration process might be a place to consider
773 implementing something like this.
776 > It strikes me that it would be very nice to be able to do things
778 > have the Job(s) backing up the machines run, and once they have all

784 > mechanism described below would probably make it very easy.
786 This is the goal. In the first step (before events), you simply
788 the Migration to tape later.
790 2. Base jobs: In ADSM, each copy of each stored file is tracked in
791 the database. Once a file (unique by path and metadata such as dates,
792 size, ownership, etc.) is in a copy pool, no more copies are made. In
793 other words, when you start ADSM, it begins like your concept of a
794 base job. After that it is in the "incremental" mode. You can
795 configure the number of "generations" of files to be retained, plus a
796 retention date after which even old generations are purged. The
797 database tracks the contents of media and projects the percentage of
798 each volume that is valid. When the valid content of a volume drops
799 below a configured percentage, the valid data are migrated to another
800 volume and the old volume is marked as empty. Note, this requires
801 ADSM to have an idea of the contents of a client, i.e. marking the
802 database when an existing file was deleted, but this would solve your
803 issue of restoring a client without restoring deleted files.
805 This is pretty far from what bacula now does, but if you are going to
806 rip things up for Base jobs,.....
807 Also, the benefits of this are huge for very large shops, especially
808 with media robots, but are a pain for shops with manual media
812 > Base jobs sound pretty useful, but I'm not dying for them.
814 Nobody is dying for them, but when you see what it does, you will die
817 3. Restoring deleted files: Since I think my comments in (2) above
818 have low probability of implementation, I'll also suggest that you
819 could approach the issue of deleted files by a mechanism of having the
820 fd report to the dir, a list of all files on the client for every
821 backup job. The dir could note in the database entry for each file
822 the date that the file was seen. Then if a restore as of date X takes
823 place, only files that exist from before X until after X would be
824 restored. Probably the major cost here is the extra date container in
825 each row of the files table.
827 Thanks for "listening". I hope some of this helps. If you want to
828 contact me, please send me an email - I read some but not all of the
829 mailing list traffic and might miss a reply there.
831 Please accept my compliments for bacula. It is doing a great job for
832 me!! I sympathize with you in the need to wrestle with excelence in
833 execution vs. excelence in feature inclusion.
838 ==============================
841 - Design at hierarchial storage for Bacula. Migration and Clone.
842 - Implement FSM (File System Modules).
843 - Audit M_ error codes to ensure they are correct and consistent.
844 - Add variable break characters to lex analyzer.
845 Either a bit mask or a string of chars so that
846 the caller can change the break characters.
847 - Make a single T_BREAK to replace T_COMMA, etc.
848 - Ensure that File daemon and Storage daemon can
849 continue a save if the Director goes down (this
850 is NOT currently the case). Must detect socket error,
851 buffer messages for later.
852 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
853 - Add ability to backup to two Storage devices (two SD sessions) at
854 the same time -- e.g. onsite, offsite.
855 - Add the ability to consolidate old backup sets (basically do a restore
856 to tape and appropriately update the catalog). Compress Volume sets.
857 Might need to spool via file is only one drive is available.
858 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
859 someway to do so with every volume that has less than x% valid
863 Migration: Move a backup from one Volume to another
864 Clone: Copy a backup -- two Volumes
866 Bacula Migration is based on Jobs (apparently Networker is file by file).
868 Migration triggered by:
872 Highwater mark (keep total size)
877 ======================================================
879 It is somewhat like a Full save becomes an incremental since
880 the Base job (or jobs) plus other non-base files.
882 - A Base backup is same as Full backup, just different type.
883 - New BaseFiles table that contains:
885 BaseJobId - Base JobId referenced for this FileId (needed ???)
886 JobId - JobId currently running
887 FileId - File not backed up, exists in Base Job
888 FileIndex - FileIndex from Base Job.
889 i.e. for each base file that exists but is not saved because
890 it has not changed, the File daemon sends the JobId, BaseId,
891 FileId, FileIndex back to the Director who creates the DB entry.
892 - To initiate a Base save, the Director sends the FD
893 the FileId, and full filename for each file in the Base.
894 - When the FD finds a Base file, he requests the Director to
895 send him the full File entry (stat packet plus MD5), or
896 conversely, the FD sends it to the Director and the Director
897 says yes or no. This can be quite rapid if the FileId is kept
898 by the FD for each Base Filename.
899 - It is probably better to have the comparison done by the FD
900 despite the fact that the File entry must be sent across the
902 - An alternative would be to send the FD the whole File entry
903 from the start. The disadvantage is that it requires a lot of
904 space. The advantage is that it requires less communications
906 - The Job record must be updated to indicate that one or more
908 - At end of Job, FD returns:
909 1. Count of base files/bytes not written to tape (i.e. matches)
910 2. Count of base file that were saved i.e. had changed.
911 - No tape record would be written for a Base file that matches, in the
912 same way that no tape record is written for Incremental jobs where
913 the file is not saved because it is unchanged.
914 - On a restore, all the Base file records must explicitly be
915 found from the BaseFile tape. I.e. for each Full save that is marked
916 to have one or more Base Jobs, search the BaseFile for all occurrences
918 - An optimization might be to make the BaseFile have:
924 This would avoid the need to explicitly fetch each File record for
925 the Base job. The Base Job record will be fetched to get the
926 VolSessionId and VolSessionTime.
927 =========================================================
930 ==========================================================
932 For each Incremental job that is run, there may be files that
933 were found but not saved because they were locked (this applies
934 only to Windows). Such a system could send back to the Director
935 a list of Unsaved files.
937 - New UnSavedFiles table that contains:
941 - Then in the next Incremental job, the list of Unsaved Files will be
942 feed to the FD, who will ensure that they are explicitly chosen even
943 if standard date/time check would not have selected them.
944 =============================================================
947 Done: (see kernsdone for more)
950 - John's Full save failed with 1.32c FD and 1.31 Dir no FD status,
951 and no error message.
952 - Add fd and st as Console keywords.
953 - Recycling volume with a Slot requires an operator intervention:
954 rufus-dir: Start Backup JobId 18, Job=kernsave.2003-11-01_21.23.52
955 rufus-dir: Pruned 1 Job on Volume Vol01 from catalog.
956 rufus-dir: There are no Jobs associated with Volume Vol01. Marking it purged.
957 rufus-dir: Recycled volume "Vol01"
958 rufus-sd: Please mount Volume "Vol01" on Storage Device "DDS-4" for Job kernsave.2003-11-01_21.23.52
959 Use "mount" command to release Job.
960 - Implement Dan's bacula script (email of 26 Oct).
961 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
962 - Edit the Client/Storage name into authentication failure messages.
963 - Fix packet too big problem. This is most likely a Windows TCP stack
965 - Implement ClientRunBeforeJob and ClientRunAfterJob.
966 - Implement forward spacing block/file: position_device(bsr) --
967 just before read_block_from_device();

1007 (just to verify it remembers where it came from, however it can be

1010 There needs to be a table of drive # to devices somewhere - If there are
1011 multiple changers or drives there may not be a 1:1 correspondance between
1012 changer drive number and system device name - and depending on the way the
1013 drives are hooked up to scsi busses, they may not be linearly numbered
1014 from an offset point either.something like
1016 Autochanger drives = 2
1017 Autochanger drive 0 = /dev/nst1
1018 Autochanger drive 1 = /dev/nst2
1019 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1020 times, not just for multidrive changers. For a 1 drive changer, that's
1026 MTX's manpage (1.2.15):
1027 unload [<slotnum>] [ <drivenum> ]
1028 Unloads media from drive <drivenum> into slot
1029 <slotnum>. If <drivenum> is omitted, defaults to
1030 drive 0 (as do all commands). If <slotnum> is
1031 omitted, defaults to the slot that the drive was
1032 loaded from. Note that there's currently no way
1033 to say 'unload drive 1's media to the slot it
1034 came from', other than to explicitly use that
1035 slot number as the destination.AB

1073 Handling removable disks
1075 From: Karl Cunningham <karlc@keckec.com>
1077 My backups are only to hard disk these days, in removable bays. This is my
1078 idea of how a backup to hard disk would work more smoothly. Some of these
1079 things Bacula does already, but I mention them for completeness. If others
1080 have better ways to do this, I'd like to hear about it.
1082 1. Accommodate several disks, rotated similar to how tapes are. Identified
1083 by partition volume ID or perhaps by the name of a subdirectory.
1084 2. Abort & notify the admin if the wrong disk is in the bay.
1085 3. Write backups to different subdirectories for each machine to be backed
1087 4. Volumes (files) get created as needed in the proper subdirectory, one
1089 5. When a disk is recycled, remove or zero all old backup files. This is
1090 important as the disk being recycled may be close to full. This may be
1091 better done manually since the backup files for many machines may be
1092 scattered in many subdirectories.
1097 - Save mount point for directories not traversed with onefs=yes.
1098 - Add seconds to start and end times in the Job report output.
1099 - if 2 concurrent backups are attempted on the same tape
1100 drive (autoloader) into different tape pools, one of them will exit
1101 fatally instead of halting until the drive is idle
1102 - Update StartTime if job held in Job Queue.
1103 - Look at www.nu2.nu/pebuilder as a helper for full windows
1104 bare metal restore. (done by Scott)
1105 - Fix orphanned buffers:
1106 Orphaned buffer: 24 bytes allocated at line 808 of rufus-dir job.c
1107 Orphaned buffer: 40 bytes allocated at line 45 of rufus-dir alist.c
1108 - Implement Preben's suggestion to add
1109 File System Types = ext2, ext3
1110 to FileSets, thus simplifying backup of *all* local partitions.
