16 Orphaned buffer: 40 bytes allocated at line 45 of rufus-dir alist.c
17 - Add dump of VolSessionId/Time and FileIndex with bls.

24 #7 Single Job Writing to Multiple Storage Devices
27 - Add Pool/Storage override regression test.
28 - Add delete JobId to regression.
29 - Add a regression test for dbcheck.
30 - New test to add bscan to four-concurrent-jobs regression,
31 i.e. after the four-concurrent jobs zap the
32 database as is done in the bscan-test, then use bscan to
33 restore the database, do a restore and compare with the
35 - Add restore of specific JobId to regression (item 3
36 on the restore prompt)
37 - Add IPv6 to regression
38 - Add database test to regression. Test each function like delete,
43 - Browse generations of files.
44 - Add offline command to Bacula console.
45 - I've seen an error when my catalog's File table fills up. I
46 then have to recreate the File table with a larger maximum row
47 size. Relevant information is at
48 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
49 "Installing and Configuring MySQL" chapter should talk a bit
50 about this potential problem, and recommend a solution.
51 - For Solaris must use POSIX awk.
52 - Want speed of writing to tape while despooling.
53 - Supported autochanger:
60 - Save mount point for directories not traversed with
62 - Implement WildFile and WildDir to solve problem of
63 saving only *.doc files.
64 - Add regex from http://www.pcre.org to Bacula for Win32.
65 - Cancel command should include JobId in list of Jobs.
66 - Require restore via the restore command or make a restore Job
67 get the bootstrap file.
68 - Use only shell tools no make in CDROM package.
69 - Document PostgreSQL performance problems bug 131.
71 - Add performance testing hooks
72 - if 2 concurrent backups are attempted on the same tape
73 drive (autoloader) into different tape pools, one of them will exit
74 fatally instead of halting until the drive is idle
75 - Add seconds to start and end times in the Job report output.
76 - Add disk seeking on restore.
77 - Document that ChangerDevice is used for Alert command.
78 - Include within include does it work?
79 - Implement a Pool of type Cleaning?
80 - Implement VolReadTime and VolWriteTime in SD
81 - Modify Backing up Your Database to include a bootstrap file.
82 - Think about making certain database errors fatal.
83 - Look at correcting the time jump in the sceduler for daylight
85 - Add a "real" timer to network connections.
86 - Tell the "restore" user when browsing is no longer possible.
87 - Write non-optimized bsrs from the JobMedia and Media records,
88 even after Files are pruned.
89 - Document that Bootstrap files can be written with cataloging
91 - Look at adding full Volume and Pool information to a Volume
92 label so that bscan can get *all* the info.
93 - Promote to Full = Time period
94 - Scratch Pool where the volumes can be re-assigned to any Pool.
95 - Update StartTime if job held in Job Queue.
96 - Despool attributes simultaneously with data in a separate
97 thread, rejoined at end of data spooling.
98 - Implement Files/Bytes,... stats for restore job.
99 - Implement Total Bytes Written, ... for restore job.
100 - Check dates entered by user for correctness (month/day/... ranges)
101 - Compress restore Volume listing by date and first file.
102 - Look at patches/bacula_db.b2z postgresql that loops during restore.
104 - Perhaps add read/write programs and/or plugins to FileSets.
105 - How to handle backing up portables ...
106 - Add some sort of guaranteed Interval for upgrading jobs.
107 - Can we write the state file after every job terminates? On Win32
108 the system crashes and the state file is not updated.
111 Documentation to do: (any release a little bit at a time)
112 - Doc to do unmount before removing magazine.
113 - Alternative to static linking "ldd prog" save all binaries listed,
114 restore them and point LD_LIBRARY_PATH to them.
115 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
116 - Document query file format.
117 - Add more documentation for bsr files.
118 - Document problems with Verify and pruning.
119 - Document how to use multiple databases.
120 - VXA drives have a "cleaning required"
121 indicator, but Exabyte recommends preventive cleaning after every 75
124 In this context, it should be noted that Exabyte has a command-line
125 vxatool utility available for free download. (The current version is
126 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
127 test the drive, unload tapes, change drive settings, flash new firmware,
129 Of particular interest in this context is that vxatool <device> -i will
130 report, among other details, the time since last cleaning in tape motion
131 minutes. This information can be retrieved (and settings changed, for
132 that matter) through the generic-SCSI device even when Bacula has the
133 regular tape device locked. (Needless to say, I don't recommend
134 changing tape settings while a job is running.)
135 - Lookup HP cleaning recommendations.
136 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
137 - Document doing table repair
140 Testing to do: (painful)
143 For 1.37 Testing/Documentation:
144 - Add bandwidth limiting.
145 - Add acks every once and a while from the SD to keep
146 the line from timing out.
147 - When an error in input occurs and conio beeps, you can back
148 up through the prompt.
149 - Detect fixed tape block mode during positioning by looking at
150 block numbers in btape "test". Possibly adjust in Bacula.
151 - Fix list volumes to output volume retention in some other
152 units, perhaps via a directive.
153 - If opening a tape in read/write mode fails attempt to open
154 it in read-only mode, and mark the tape for read only.
155 - Add a read-only mode to the mount option.
156 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
157 with multiple priorities.
158 - If you use restore replace=never, the directory attributes for
159 non-existent directories will not be restored properly.
161 - see lzma401.zip in others directory for new compression
163 - Minimal autochanger handling in Bacula and in btape.
164 - Look into how tar does not save sockets and the possiblity of
165 not saving them in Bacula (Martin Simmons reported this).
166 - Add All Local Partitions = yes to new style saves.
167 - localmounts=`awk '/ext/ { print $2 }' /proc/mounts` # or whatever
168 find $localmounts -xdev -type s -ls
169 - Fix restore jobs so that multiple jobs can run if they
170 are not using the same tape(s).
171 - Allow the user to select JobType for manual pruning/purging.
172 - Look at adding Client run command that will use the
173 port opened by the client.
174 - bscan does not put first of two volumes back with all info in
176 - Implement the FreeBSD nodump flag in chflags.
177 - Figure out how to make named console messages go only to that
178 console and to the non-restricted console (new console class?).
179 - Make restricted console prompt for password if *ask* is set or
180 perhaps if password is undefined.
181 - Implement "from ISO-date/time every x hours/days/weeks/months" in
183 ==== from Marc Schoechlin
184 - the help-command should be more verbose
185 (it should explain the paramters of the different
187 -> it´s time-comsuming to consult the manual anytime
188 you need a special parameter
189 -> maybe it´s more easy to maintain this, if the
190 descriptions of that commands are outsourced to
192 - the cd-command should allow complete paths
193 i.e. cd /foo/bar/foo/bar
194 -> if a customer mails me the path to a certain file,
195 it´s faster to enter the specified directory
196 - if the password is not configured in bconsole.conf
197 you should be asked for it.
198 -> sometimes you like to do restore on a customer-machine
199 which shouldn´t know the password for bacula.
200 -> adding the password to the file favours admins
201 to forget to remove the password after usage
203 the protection of that file is less important
204 - long-listed-output of commands should be scrollable
205 like the unix more/less-command does
206 -> if someone runs 200 and more machines, the lists could
207 be a little long and complex
208 - command-output should be shown column by column
209 to reduce scrolling and to increase clarity
211 - lsmark should list the selected files with full
213 - wildcards for selecting and file and directories would be nice
214 - any actions should be interuptable with STRG+C
215 - command-expansion would be pretty cool
217 - Compaction of Disk space by "migrating" Volumes that have pruned
218 Jobs (what criteria? size, #jobs, time).
219 - Add prune all command
220 - Document fact that purge can destroy a part of a restore by purging
221 one volume while others remain valid -- perhaps mark Jobs.
222 - Add multiple-media-types.txt
223 - look at mxt-changer.html
224 - Make ? do a help command (no return needed).
225 - Implement restore directory.
226 - Document streams and how to implement them.
227 - Try not to re-backup a file if a new hard link is added.
228 - Add feature to backup hard links only, but not the data.
229 - Fix stream handling to be simpler.
230 - Add Priority and Bootstrap to Run a Job.
231 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
233 - Remove View FileSet button from Run a Job dialog.
234 - Handle prompt for restore job at end of Restore command.
235 - Add display of total selected files to Restore window.
236 - Add tree pane to left of window.
237 - Add progress meter.
238 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
239 - Document writing to a CD/DVD with Bacula.
240 - Add a "base" package to the window installer for pthreadsVCE.dll
241 which is needed by all packages.
242 - Add message to user to check for fixed block size when the forward
243 space test fails in btape.
244 - When unmarking a directory check if all files below are unmarked and
245 then remove the + flag -- in the restore tree.
246 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
247 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
248 - Revisit the question of multiple Volumes (disk) on a single device.
249 - Add a block copy option to bcopy.
250 - Investigate adding Mac Resource Forks.
251 - Finish work on Gnome restore GUI.
252 - Fix "llist jobid=xx" where no fileset or client exists.
254 it seems to be complaining about 12:00pm which should be a valid 12
255 hour time. I changed the time to 11:59am and everything works fine.
256 Also 12:00am works fine. 0:00pm also works (which I don't think
257 should). None of the values 12:00pm - 12:59pm work for that matter.
258 - Add level to estimate command.
259 - For each job type (Admin, Restore, ...) require only the really necessary
261 - Fix option 2 of restore -- list where file is backed up -- require Client,
262 then list last 20 backups.
263 - Pass Director resource name as an option to the Console.
264 - Add a "batch" mode to the Console (no unsolicited queries, ...).
265 - Add a .list all files in the restore tree (probably also a list all files)
266 Do both a long and short form.
267 - Allow browsing the catalog to see all versions of a file (with
268 stat data on each file).
269 - Restore attributes of directory if replace=never set but directory
271 - Use SHA1 on authentication if possible.
272 - See comtest-xxx.zip for Windows code to talk to USB.
273 - Add Events and Perl scripting.
274 - Add John's appended files:
275 Appended = { /files/server/logs/http/*log }
276 and such files would be treated as follows.On a FULL backup, they would
277 be backed up like any other file.On an INCREMENTAL backup, where a
278 previous INCREMENTAL or FULL was already in thecatalogue and the length
279 of the file wasgreater than the length of the last backup, only thedata
280 added since the last backup will be dumped.On an INCREMENTAL backup, if
281 the length of the file is less than thelength of the file with the same
282 name last backed up, the completefile is dumped.On Windows systems, with
283 creation date of files, we can be evensmarter about this and not count
284 entirely upon the length.On a restore, the full and all incrementals
285 since it will beapplied in sequence to restore the file.
286 - Allow for optional cancelling of SD and FD in case DIR
287 gets a fatal error. Requested by Jesse Guardiani <jesse@wingnet.net>
288 - Add "limit=n" for "list jobs"
289 - Check new HAVE_WIN32 open bits.
290 - Check if the tape has moved before writing.
291 - Handling removable disks -- see below:
292 - Keep track of tape use time, and report when cleaning is necessary.
293 - Add FromClient and ToClient keywords on restore command (or
294 BackupClient RestoreClient).
295 - Implement a JobSet, which groups any number of jobs. If the
296 JobSet is started, all the jobs are started together.
297 Allow Pool, Level, and Schedule overrides.
298 - Enhance cancel to timeout BSOCK packets after a specific delay.
299 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
300 ua_status.!!! Thanks to Alan Brown for this tip.
301 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
302 correctly for multiple simultaneous jobs.
303 - Correct code so that FileSet MD5 is calculated for < and | filename
305 - Implement the Media record flag that indicates that the Volume does disk
307 - Implement VolAddr, which is used when Volume is addressed like a disk,
308 and form it from VolFile and VolBlock.
309 - Make multiple restore jobs for multiple media types specifying
310 the proper storage type.
311 - Implement MediaType keyword in bsr?
312 - Fix fast block rejection (stored/read_record.c:118). It passes a null
313 pointer (rec) to try_repositioning().
314 - Look at extracting Win data from BackupRead.
315 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
316 which would take precidence over the Catalog "JobRetention".
317 - Implement Label Format in Add and Label console commands.
318 - Possibly up network buffers to 65K. Put on variable.
319 - Put email tape request delays on one or more variables. User wants
320 to cancel the job after a certain time interval. Maximum Mount Wait?
321 - Job, Client, Device, Pool, or Volume?
322 Is it possible to make this a directive which is *optional* in multiple
323 resources, like Level? If so, I think I'd make it an optional directive
324 in Job, Client, and Pool, with precedence such that Job overrides Client
325 which in turn overrides Pool.
327 - New Storage specifications:
328 - Want to write to multiple storage devices simultaneously
329 - Want to write to multiple storage devices sequentially (in one job)
330 - Want to read/write simultaneously
331 - Key is MediaType -- it must match
333 Passed to SD as a sort of BSR record called Storage Specification
337 MediaType -> Next MediaType
339 Device -> Next Device
341 Allow multiple Storage specifications
349 Allow Multiple Pool specifications (note, Pool currently
351 Allow Multiple MediaType specifications in Dir conf
352 Allow Multiple Device specifications in Dir conf
353 Perhaps keep this in a single SSR
354 Tie a Volume to a specific device by using a MediaType that
355 is contained in only one device.
356 In SD allow Device to have Multiple MediaTypes
358 - Look at www.nu2.nu/pebuilder as a helper for full windows
360 - Ideas from Jerry Scharf:
361 First let's point out some big pluses that bacula has for this
363 more importantly it's active. Thank you so much for that
364 even more important, it's not flaky
365 it has an open access catalog, opening many possibilities
366 it's pushing toward heterogeneous systems capability
368 Macintosh file client
369 macs are an interesting niche, but I fear a server is a rathole
370 working bare iron recovery for windows
371 the option for inc/diff backups not reset on fileset revision
372 a) use both change and inode update time against base time
373 b) do the full catalog check (expensive but accurate)
374 sizing guide (how much system is needed to back up N systems/files)
375 consultants on using bacula in building a disaster recovery system
377 or how to get at fancy things that one could do with bacula
378 logwatch code for bacula logs (or similar)
379 linux distro inclusion of bacula (brings good and bad, but necessary)
380 win2k/XP server capability (icky but you asked)
381 support for Oracle database ??
383 - Look at adding SQL server and Exchange support for Windows.
384 - Each DVD-RAM disk would be a volume, just like each tape is
385 a volume. It's a 4.7GB media with random access, but there's nothing about
386 it that I can see that makes it so different than a tape from bacula's
387 perspective. Why couldn't I back up to a bare floppy as a volume (ignoring
389 - Make dev->file and dev->block_num signed integers so that -1 can
390 be an invalid value which happens with BSR.
391 - Create VolAddr for disk files in place of VolFile and VolBlock. This
392 is needed to properly specify ranges.
393 - Add progress of files/bytes to SD and FD.
394 - Print warning message if FileId > 4 billion
395 - do a "messages" before the first prompt in Console
396 - Add a date and time stamp at the beginning of every line in the
397 Job report (Volker Sauer).
398 - Client does not show busy during Estimate command.
399 - Implement Console mtx commands.
400 - Implement a Mount Command and an Unmount Command where
401 the users could specify a system command to be performed
402 to do the mount, after which Bacula could attempt to
403 read the device. This is for Removeable media such as a CDROM.
404 - Most likely, this mount command would be invoked explicitly
405 by the user using the current Console "mount" and "unmount"
406 commands -- the Storage Daemon would do the right thing
407 depending on the exact nature of the device.
408 - As with tape drives, when Bacula wanted a new removable
409 disk mounted, it would unmount the old one, and send a message
410 to the user, who would then use "mount" as described above
411 once he had actually inserted the disk.
412 - Implement dump/print label to UA
413 - Spool to disk only when the tape is full, then when a tape is hung move
415 - bextract is sending everything to the log file ****FIXME****
416 - Allow multiple Storage specifications (or multiple names on
417 a single Storage specification) in the Job record. Thus a job
418 can be backed up to a number of storage devices.
419 - Implement some way for the File daemon to contact the Director
420 to start a job or pass its DHCP obtained IP number.
421 - Implement a query tape prompt/replace feature for a console
422 - Copy console @ code to gnome2-console
423 - Make AES the only encryption algorithm see
424 http://csrc.nist.gov/CryptoToolkit/aes/). It's
425 an officially adopted standard, has survived peer
426 review, and provides keys up to 256 bits.
427 - Take a careful look at SetACL http://setacl.sourceforge.net
428 - Take a careful look at Level for the estimate command, maybe make
429 it a command line option.
430 - Add Volume name to "I cannot write on this volume because"
431 - Make tree walk routines like cd, ls, ... more user friendly
432 by handling spaces better.
433 - Make sure that Bacula rechecks the tape after the 20 min wait.
434 - Set IO_NOWAIT on Bacula TCP/IP packets.
435 - Try doing a raw partition backup and restore by mounting a
438 Yes, it would allow to highly automatic the request for new tapes. If a
439 tape is empty, bacula reads the barcodes (native or simulated), and if
440 an unused tape is found, it runs the label command with all the
441 necessary parameters.
443 By the way can bacula automatically "move" an empty/purged volume say
444 in the "short" pool to the "long" pool if this pool runs out of volume
446 - What to do about "list files job=xxx".
447 - Make Dmsg look at global before calling subroutine.
448 - Get and test MySQL 4.0
449 - Look at how fuser works and /proc/PID/fd that is how Nic found the
450 file descriptor leak in Bacula.
451 - Implement WrapCounters in Counters.
452 - Add heartbeat from FD to SD if hb interval expires.
453 - Can we dynamically change FileSets?
454 - If pool specified to label command and Label Format is specified,
455 automatically generate the Volume name.
456 - Why can't SQL do the filename sort for restore?
457 - Look into Microsoft Volume Shadowcopy Service VSS for backing
458 up system state components (Active Directory, System Volume, ...)
459 - Add ExhautiveRestoreSearch
460 - Look at the possibility of loading only the necessary
461 data into the restore tree (i.e. do it one directory at a
462 time as the user walks through the tree).
463 - Possibly use the hash code if the user selects all for a restore command.
464 - Fix "restore all" to bypass building the tree.
465 - Prohibit backing up archive device (findlib/find_one.c:128)
466 - Implement Release Device in the Job resource to unmount a drive.
467 - Implement Acquire Device in the Job resource to mount a drive,
468 be sure this works with admin jobs so that the user can get
469 prompted to insert the correct tape. Possibly some way to say to
470 run the job but don't save the files.
471 - Make things like list where a file is saved case independent for
474 - Use autochanger to handle multiple devices.
475 - Add SuSE install doc to list.
476 - Check and rechedk "Invalid block number"
477 - User wants to NOT backup up certain big files (email files).
478 - Maybe remove multiple simultaneous devices code in SD.
479 - On Windows with very long path names, it may be impossible to create
480 a file (and thus restore it) because the total length is too long.
481 We must cd into the directory then create the file without the
483 - Implement a Recycle command
484 - Add client name to cram-md5 challenge so Director can immediately
485 verify if it is the correct client.
486 - Audit all UA commands to ensure that we always prompt where possible.
487 - Make bootstrap filename unique.
488 - Test a second language e.g. french.
489 - Start working on Base jobs.
490 - Implement UnsavedFiles DB record.
491 - Implement argc/argv for daemon command line scanning using table driven
493 - From Phil Stracchino:
494 It would probably be a per-client option, and would be called
495 something like, say, "Automatically purge obsoleted jobs". What it
496 would do is, when you successfully complete a Differential backup of a
497 client, it would automatically purge all Incremental backups for that
498 client that are rendered redundant by that Differential. Likewise,
499 when a Full backup on a client completed, it would automatically purge
500 all Differential and Incremental jobs obsoleted by that Full backup.
501 This would let people minimize the number of tapes they're keeping on
502 hand without having to master the art of retention times.
503 - Implement a M_SECURITY message class.
504 - When doing a Backup send all attributes back to the Director, who
505 would then figure out what files have been deleted.
506 - Currently in mount.c:236 the SD simply creates a Volume. It should have
507 explicit permission to do so. It should also mark the tape in error
508 if there is an error.
509 - SD Bytes Read is wrong.
510 - Investigate doing RAW backup of Win32 partition.
511 - Cancel waiting for Client connect in SD if FD goes away.
513 - Implement timeout in response() when it should come quickly.
514 - Implement console @echo command.
515 - Implement a Slot priority (loaded/not loaded).
516 - Implement "vacation" Incremental only saves.
517 - Implement single pane restore (much like the Gftp panes).
518 - Implement Automatic Mount even in operator wait.
519 - Implement create "FileSet"?
520 - Implement restore "current system", but take all files without
521 doing selection tree -- so that jobs without File records can
523 - Add prefixlinks to where or not where absolute links to FD.
524 - Issue message to mount a new tape before the rewind.
525 - Simplified client job initiation for portables.
526 - If SD cannot open a drive, make it periodically retry.
527 - Add more of the config info to the tape label.
529 - If tape is marked read-only, then try opening it read-only rather than
530 failing, and remember that it cannot be written.
531 - Refine SD waiting output:
532 Device is being positioned
533 > Device is being positioned for append
534 > Device is being positioned to file x
536 - Figure out some way to estimate output size and to avoid splitting
537 a backup across two Volumes -- this could be useful for writing CDROMs
538 where you really prefer not to have it split -- not serious.
539 - Have SD compute MD5 or SHA1 and compare to what FD computes.
540 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
541 actual data on the Volume and compare it.
542 - Implement Bacula plugins -- design API
543 - Make bcopy read through bad tape records.
544 - Program files (i.e. execute a program to read/write files).
545 Pass read date of last backup, size of file last time.
546 - Add Signature type to File DB record.
547 - CD into subdirectory when open()ing files for backup to
548 speed up things. Test with testfind().
549 - Priority job to go to top of list.
550 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
551 - Implement some way for the Console to dynamically create a job.
552 - Restore to a particular time -- e.g. before date, after date.

678 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>

680 Subject: RE: [Bacula-users] future large programming jobs
681 Date: Thu, 26 Feb 2004 11:34:54 -0600
683 I noticed the subject thread and thought I would offer the following
684 merely as sources of ideas, i.e. something to think about, not even as
685 strong as a request. In my former life (before retiring) I often
686 dealt with backups and storage management issues/products as a
687 developer and as a consultant. I am currently migrating my personal
688 network from amanda to bacula specifically because of the ability to
689 cross media boundaries during storing backups.
690 Are you familiar with the commercial product called ADSM (I think IBM
691 now sells it under the Tivoli label)? It has a couple of interesting
692 ideas that may apply to the following topics.
694 1. Migration: Consider that when you need to restore a system, there
695 may be pressure to hurry. If all the information for a single client
696 can eventually end up on the same media (and in chronological order),
697 the restore is facillitated by not having to search past information
698 from other clients. ADSM has the concept of "client affinity" that
699 may be associated with it's storage pools. It seems to me that this
700 concept (as an optional feature) might fit in your architecture for
703 ADSM also has the concept of defining one or more storage pools as
704 "copy pools" (almost mirrors, but only in the sense of contents).
705 These pools provide the ability to have duplicte data stored both
706 onsite and offsite. The copy process can be scheduled to be handled
707 by their storage manager during periods when there is no backup
708 activity. Again, the migration process might be a place to consider
709 implementing something like this.
712 > It strikes me that it would be very nice to be able to do things
714 > have the Job(s) backing up the machines run, and once they have all

720 > mechanism described below would probably make it very easy.
722 This is the goal. In the first step (before events), you simply
724 the Migration to tape later.
726 2. Base jobs: In ADSM, each copy of each stored file is tracked in
727 the database. Once a file (unique by path and metadata such as dates,
728 size, ownership, etc.) is in a copy pool, no more copies are made. In
729 other words, when you start ADSM, it begins like your concept of a
730 base job. After that it is in the "incremental" mode. You can
731 configure the number of "generations" of files to be retained, plus a
732 retention date after which even old generations are purged. The
733 database tracks the contents of media and projects the percentage of
734 each volume that is valid. When the valid content of a volume drops
735 below a configured percentage, the valid data are migrated to another
736 volume and the old volume is marked as empty. Note, this requires
737 ADSM to have an idea of the contents of a client, i.e. marking the
738 database when an existing file was deleted, but this would solve your
739 issue of restoring a client without restoring deleted files.
741 This is pretty far from what bacula now does, but if you are going to
742 rip things up for Base jobs,.....
743 Also, the benefits of this are huge for very large shops, especially
744 with media robots, but are a pain for shops with manual media
748 > Base jobs sound pretty useful, but I'm not dying for them.
750 Nobody is dying for them, but when you see what it does, you will die
753 3. Restoring deleted files: Since I think my comments in (2) above
754 have low probability of implementation, I'll also suggest that you
755 could approach the issue of deleted files by a mechanism of having the
756 fd report to the dir, a list of all files on the client for every
757 backup job. The dir could note in the database entry for each file
758 the date that the file was seen. Then if a restore as of date X takes
759 place, only files that exist from before X until after X would be
760 restored. Probably the major cost here is the extra date container in
761 each row of the files table.
763 Thanks for "listening". I hope some of this helps. If you want to
764 contact me, please send me an email - I read some but not all of the
765 mailing list traffic and might miss a reply there.
767 Please accept my compliments for bacula. It is doing a great job for
768 me!! I sympathize with you in the need to wrestle with excelence in
769 execution vs. excelence in feature inclusion.
774 ==============================
777 - Design at hierarchial storage for Bacula. Migration and Clone.
778 - Implement FSM (File System Modules).
779 - Audit M_ error codes to ensure they are correct and consistent.
780 - Add variable break characters to lex analyzer.
781 Either a bit mask or a string of chars so that
782 the caller can change the break characters.
783 - Make a single T_BREAK to replace T_COMMA, etc.
784 - Ensure that File daemon and Storage daemon can
785 continue a save if the Director goes down (this
786 is NOT currently the case). Must detect socket error,
787 buffer messages for later.
788 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
789 - Add ability to backup to two Storage devices (two SD sessions) at
790 the same time -- e.g. onsite, offsite.
791 - Add the ability to consolidate old backup sets (basically do a restore
792 to tape and appropriately update the catalog). Compress Volume sets.
793 Might need to spool via file is only one drive is available.
794 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
795 someway to do so with every volume that has less than x% valid
799 Migration: Move a backup from one Volume to another
800 Clone: Copy a backup -- two Volumes
802 Bacula Migration is based on Jobs (apparently Networker is file by file).
804 Migration triggered by:
808 Highwater mark (keep total size)
813 ======================================================
815 It is somewhat like a Full save becomes an incremental since
816 the Base job (or jobs) plus other non-base files.
818 - A Base backup is same as Full backup, just different type.
819 - New BaseFiles table that contains:
821 BaseJobId - Base JobId referenced for this FileId (needed ???)
822 JobId - JobId currently running
823 FileId - File not backed up, exists in Base Job
824 FileIndex - FileIndex from Base Job.
825 i.e. for each base file that exists but is not saved because
826 it has not changed, the File daemon sends the JobId, BaseId,
827 FileId, FileIndex back to the Director who creates the DB entry.
828 - To initiate a Base save, the Director sends the FD
829 the FileId, and full filename for each file in the Base.
830 - When the FD finds a Base file, he requests the Director to
831 send him the full File entry (stat packet plus MD5), or
832 conversely, the FD sends it to the Director and the Director
833 says yes or no. This can be quite rapid if the FileId is kept
834 by the FD for each Base Filename.
835 - It is probably better to have the comparison done by the FD
836 despite the fact that the File entry must be sent across the
838 - An alternative would be to send the FD the whole File entry
839 from the start. The disadvantage is that it requires a lot of
840 space. The advantage is that it requires less communications
842 - The Job record must be updated to indicate that one or more
844 - At end of Job, FD returns:
845 1. Count of base files/bytes not written to tape (i.e. matches)
846 2. Count of base file that were saved i.e. had changed.
847 - No tape record would be written for a Base file that matches, in the
848 same way that no tape record is written for Incremental jobs where
849 the file is not saved because it is unchanged.
850 - On a restore, all the Base file records must explicitly be
851 found from the BaseFile tape. I.e. for each Full save that is marked
852 to have one or more Base Jobs, search the BaseFile for all occurrences
854 - An optimization might be to make the BaseFile have:
860 This would avoid the need to explicitly fetch each File record for
861 the Base job. The Base Job record will be fetched to get the
862 VolSessionId and VolSessionTime.
863 =========================================================
866 ==========================================================
868 For each Incremental job that is run, there may be files that
869 were found but not saved because they were locked (this applies
870 only to Windows). Such a system could send back to the Director
871 a list of Unsaved files.
873 - New UnSavedFiles table that contains:
877 - Then in the next Incremental job, the list of Unsaved Files will be
878 feed to the FD, who will ensure that they are explicitly chosen even
879 if standard date/time check would not have selected them.
880 =============================================================
883 Done: (see kernsdone for more)
886 - John's Full save failed with 1.32c FD and 1.31 Dir no FD status,
887 and no error message.
888 - Add fd and st as Console keywords.
889 - Recycling volume with a Slot requires an operator intervention:
890 rufus-dir: Start Backup JobId 18, Job=kernsave.2003-11-01_21.23.52
891 rufus-dir: Pruned 1 Job on Volume Vol01 from catalog.
892 rufus-dir: There are no Jobs associated with Volume Vol01. Marking it purged.
893 rufus-dir: Recycled volume "Vol01"
894 rufus-sd: Please mount Volume "Vol01" on Storage Device "DDS-4" for Job kernsave.2003-11-01_21.23.52
895 Use "mount" command to release Job.
896 - Implement Dan's bacula script (email of 26 Oct).
897 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
898 - Edit the Client/Storage name into authentication failure messages.
899 - Fix packet too big problem. This is most likely a Windows TCP stack
901 - Implement ClientRunBeforeJob and ClientRunAfterJob.
902 - Implement forward spacing block/file: position_device(bsr) --
903 just before read_block_from_device();

943 (just to verify it remembers where it came from, however it can be
944 overrriden with mtx unload {slotnumber} to go to any storage slot.)
946 There needs to be a table of drive # to devices somewhere - If there are
947 multiple changers or drives there may not be a 1:1 correspondance between
948 changer drive number and system device name - and depending on the way the
949 drives are hooked up to scsi busses, they may not be linearly numbered
950 from an offset point either.something like
952 Autochanger drives = 2
953 Autochanger drive 0 = /dev/nst1
954 Autochanger drive 1 = /dev/nst2
955 IMHO, it would be _safest_ to use explicit mtx unload commands at all
956 times, not just for multidrive changers. For a 1 drive changer, that's
962 MTX's manpage (1.2.15):
963 unload [<slotnum>] [ <drivenum> ]
964 Unloads media from drive <drivenum> into slot
965 <slotnum>. If <drivenum> is omitted, defaults to
966 drive 0 (as do all commands). If <slotnum> is
967 omitted, defaults to the slot that the drive was
968 loaded from. Note that there's currently no way
969 to say 'unload drive 1's media to the slot it
970 came from', other than to explicitly use that
971 slot number as the destination.AB

1009 Handling removable disks
1011 From: Karl Cunningham <karlc@keckec.com>
1013 My backups are only to hard disk these days, in removable bays. This is my
1014 idea of how a backup to hard disk would work more smoothly. Some of these
1015 things Bacula does already, but I mention them for completeness. If others
1016 have better ways to do this, I'd like to hear about it.
1018 1. Accommodate several disks, rotated similar to how tapes are. Identified
1019 by partition volume ID or perhaps by the name of a subdirectory.
1020 2. Abort & notify the admin if the wrong disk is in the bay.
1021 3. Write backups to different subdirectories for each machine to be backed
1023 4. Volumes (files) get created as needed in the proper subdirectory, one
1025 5. When a disk is recycled, remove or zero all old backup files. This is
1026 important as the disk being recycled may be close to full. This may be
1027 better done manually since the backup files for many machines may be
1028 scattered in many subdirectories.
1033 - Add "Rerun failed levels = yes/no" to Job resource.
1034 - Fix CDROM make script to permit picking up already installed
1036 - Add date/time to each Jmsg.
