4 Documentation to do: (any release a little bit at a time)
5 - Document query file format.
6 - Document problems with Verify and pruning.
7 - Document how to use multiple databases.
8 - VXA drives have a "cleaning required"
9 indicator, but Exabyte recommends preventive cleaning after every 75
12 In this context, it should be noted that Exabyte has a command-line
13 vxatool utility available for free download. (The current version is
14 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
15 test the drive, unload tapes, change drive settings, flash new firmware,
17 Of particular interest in this context is that vxatool <device> -i will
18 report, among other details, the time since last cleaning in tape motion
19 minutes. This information can be retrieved (and settings changed, for
20 that matter) through the generic-SCSI device even when Bacula has the
21 regular tape device locked. (Needless to say, I don't recommend
22 changing tape settings while a job is running.)
23 - Lookup HP cleaning recommendations.
24 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
26 Testing to do: (painful)
28 - blocksize recognition code.
29 - Test if rewind at end of tape waits for tape to rewind.
32 For 1.33 Testing/Documentation:
33 - Figure out how to use ssh or stunnel to protect Bacula communications.
34 Add Dan's work to manual See ssl.txt
35 - Add db check test to regression. Test each function like delete,
37 - If you use restore replace=never, the directory attributes for
38 non-existent directories will not be restored properly.
41 - Add multiple-media-types.txt
42 - look at mxt-changer.html
46 - Try not to re-backup a file if a new hard link is added.
47 - Backup hard links only, but not the data.
48 - Add "All Local = yes" option to save to include all local partitions.
49 - Fix stream handling to be simpler.
50 - Add Priority and Bootstrap to Run a Job.
51 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
53 - Remove View FileSet button from Run a Job dialog.
54 - Don't count higher level non-saved directories in Files expected
56 - Handle prompt for restore job at end of Restore command.
57 - Add display of total selected files to Restore window.
58 - Add tree pane to left of window.
60 - Polling does not work for restore. It tries a number of times,
61 gives up, and crashes the FD.
62 - Lock jcr_chain when doing attach/detach in acquire.c
63 - Add assert in free_jcr if attach/detach chain active.
64 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
65 - Document writing to a CD/DVD with Bacula.
66 - Add check for tape alerts.
67 - Add a "base" package to the window installer for pthreadsVCE.dll
68 which is needed by all packages.
69 - Add message to user to check for fixed block size when the forward
70 space test fails in btape.
71 - When unmarking a directory check if all files below are unmarked and
72 then remove the + flag -- in the restore tree.
73 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
74 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
75 - Revisit the question of multiple Volumes (disk) on a single device.
77 - Check that all change in wait status in the SD are
78 signaled to the Director.
79 - Add a block copy option to bcopy.
80 - Investigate adding Mac Resource Forks.
81 - Finish work on Gnome restore GUI.
82 - Fix "llist jobid=xx" where no fileset or client exists.
84 it seems to be complaining about 12:00pm which should be a valid 12
85 hour time. I changed the time to 11:59am and everything works fine.
86 Also 12:00am works fine. 0:00pm also works (which I don't think
87 should). None of the values 12:00pm - 12:59pm work for that matter.
88 - Add level to estimate command.
89 - Fix option 2 of restore -- list where file is backed up -- require Client,
90 then list last 20 backups.
91 - Add all pools in Dir conf to DB also update them to catch changed
92 LabelFormats and such.
93 - Update volumes FromPool=xxx does all volumes.
94 - Pass Director resource name as an option to the Console.
95 - Add a "batch" mode to the Console (no unsolicited queries, ...).
96 - Add code to check for tape alerts -- tapeinfo.
97 - Make sure list of Volumes needed is in correct order for restore.
99 - Remove paths (and files that reference them) that have no trailing slash
100 in dbcheck -- or add a trailing slash.
101 - Remove Filenames (and files that reference them) that have a trailing
102 slash in dbcheck -- or remove the trailing slash.
103 - Remove orphaned paths/filenames by copying them to a new table with a
104 reference count, then mark all referenced files/paths and remove unreferenced
106 - Add a .list all files in the restore tree (probably also a list all files)
107 Do both a long and short form.
108 - Allow browsing the catalog to see all versions of a file (with
109 stat data on each file).
110 - Restore attributes of directory if replace=never set but directory
112 - Allow "delete job jobid=xxx,yyy,aaa-bbb" i.e. list + ranges.
113 - Use SHA1 on authentication if possible.
114 - See comtest-xxx.zip for Windows code to talk to USB.
115 - Make btape accept Device Names in addition to Archive names.
116 - Add Events and Perl scripting.
117 - Add John's appended files:
118 Appended = { /files/server/logs/http/*log }
119 and such files would be treated as follows.On a FULL backup, they would
120 be backed up like any other file.On an INCREMENTAL backup, where a
121 previous INCREMENTAL or FULL was already in thecatalogue and the length
122 of the file wasgreater than the length of the last backup, only thedata
123 added since the last backup will be dumped.On an INCREMENTAL backup, if
124 the length of the file is less than thelength of the file with the same
125 name last backed up, the completefile is dumped.On Windows systems, with
126 creation date of files, we can be evensmarter about this and not count
127 entirely upon the length.On a restore, the full and all incrementals
128 since it will beapplied in sequence to restore the file.
129 - Add a regression test for dbcheck.
130 - Add disk seeking on restore. - Allow
131 for optional cancelling of SD and FD in case DIR
132 gets a fatal error. Requested by Jesse Guardiani <jesse@wingnet.net>
133 - Bizarre message: Error: Could not open WriteBootstrap file:
134 - Build console in client only build.
135 - Add "limit=n" for "list jobs"
136 - Check new HAVE_WIN32 open bits.
137 - Check if the tape has moved before writing.
138 - Handling removable disks -- see below:
139 - Multiple drive autochanger support -- see below.
140 - Keep track of tape use time, and report when cleaning is necessary.
141 - Fix FreeBSD mt_count problem.
142 - Add FromClient and ToClient keywords on restore command (or
143 BackupClient RestoreClient).
144 - Automatic "update slots" on user configuration directive when a
146 - Implement a JobSet, which groups any number of jobs. If the
147 JobSet is started, all the jobs are started together.
148 Allow Pool, Level, and Schedule overrides.
149 - Enhance cancel to timeout BSOCK packets after a specific delay.
150 - When I restore to Windows the Created, Accessed and Modifiedtimes are
151 those of the time of the restore, not those of the originalfile.
152 The dates you will find in your restore log seem to be the original
154 - Volume "add"ed to Pool gets recycled in first use. VolBytes=0
155 - If a tape is recycled while it is mounted, Stanislav Tvrudy must do an
156 additional mount to deblock the job.
158 bscan: sql_update.c:65 UPDATE File SET MD5='Ij+5kwN6TFIxK+8l8+/I+A' WHERE FileId=0
159 bscan: bscan.c:1074 Could not add MD5/SHA1 to File record. ERR=sql_update.c:65 Update problem: affected_rows=0
160 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
161 ua_status.!!! Thanks to Alan Brown for this tip.
162 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
163 correctly for multiple simultaneous jobs.
164 - Correct code so that FileSet MD5 is calculated for < and | filename
166 - Mark Volume in error on error from WEOF.
167 - Implement the Media record flag that indicates that the Volume does disk
169 - Implement VolAddr, which is used when Volume is addressed like a disk,
170 and form it from VolFile and VolBlock.
171 - Make multiple restore jobs for multiple media types specifying
172 the proper storage type.
173 - Implement MediaType keyword in bsr?
174 - Fix fast block rejection (stored/read_record.c:118). It passes a null
175 pointer (rec) to try_repositioning().
176 - Look at extracting Win data from BackupRead.
177 - Having dashes in filenames apparently creates problems for restore
178 by filename??? hard to believe.
179 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
180 which would take precidence over the Catalog "JobRetention".
181 - Implement Label Format in Add and Label console commands.
182 - Possibly up network buffers to 65K. Put on variable.
183 - Put email tape request delays on one or more variables. User wants
184 to cancel the job after a certain time interval. Maximum Mount Wait?
185 - Job, Client, Device, Pool, or Volume?
186 Is it possible to make this a directive which is *optional* in multiple
187 resources, like Level? If so, I think I'd make it an optional directive
188 in Job, Client, and Pool, with precedence such that Job overrides Client
189 which in turn overrides Pool.
190 - Print a message when a job starts if the conf file is not current.
192 - Spooling ideas taken from Volker Sauer's and other's emails:
193 > IMHO job spooling should be turned on
199 > where and 2) overrides 1) and 3) is independent.
201 Yes, this is the minimum that I think is necessary.
205 > It should be switched by job, because the job that backs up the machine
206 > with the bacula-sd on doesn't need spooling.
207 > It should be switched by schedule, because for full-backups I don't need
208 > spooling, so I can switch it off (because the network faster then the
211 True, with the exception that if you have enough disk spool space,
212 and you want to run concurrent jobs, spooling can eliminate the block
213 interleaving restore inefficiencies.
215 > And you should be able to turn it of by sd for sd-machines with low disk
216 > capacity or if you just don't need or want this feature.
219 > - definitly the possibility for multipe spool direcories
221 Having multiple directories is no problem -- having different maximum
222 sizes creates specification problems. At some point, I will probably
223 have a common SD pool of spool directories as well as a set of
224 private spool directories for each device. The first implementation
225 will be a set of private spool directories for each device since
226 managing a global pool with a bunch of threads writing into the same
227 directory is *much* more complicated and prone to error.
229 > - the ability to spool parts of a backup (not the whole client)
231 This may change in the future, but for the moment, it will spool
232 either to a job high water mark, or until the directory is full
233 (reaches max spool size or I/O error). It will then write to tape,
234 truncate the spool file, and begin spooling again.
236 > - spooling while writing to tape
238 Not within a job, but yes, if you run concurrent jobs -- each is a
239 different thread. Within a job could be a feature, but *much* later.
241 > - parallel spooling (like parallel jobs/ concurrent jobs) of clients
243 Yes, this is one of my main motivations for doing it (aside from
244 eliminating tape "shoe shine" during incremental backups.
246 > - flushing a backup that only went to disk (like amflush in amanda)
248 This will be a future feature, since spooling is different from backing
249 up to disk. The future feature will be "migration" which will move a job
250 from one backup Volume to another.
252 - New Storage specifications:
253 Passed to SD as a sort of BSR record called Storage Specification
257 MediaType -> Next MediaType
259 Device -> Next Device
260 Write Copy Resource that makes a copy of a resource.
262 Allow multiple Storage specifications
270 Allow Multiple Pool specifications (note, Pool currently
272 Allow Multiple MediaType specifications
273 Allow Multiple Device specifications
274 Perhaps keep this in a single SSR
275 Tie a Volume to a specific device by using a MediaType that
276 is contained in only one device.
277 In SD allow Device to have Multiple MediaTypes
280 - Look at www.nu2.nu/pebuilder as a helper for full windows
282 Ideas from Jerry Scharf:
283 First let's point out some big pluses that bacula has for this
285 more importantly it's active. Thank you so much for that
286 even more important, it's not flaky
287 it has an open access catalog, opening many possibilities
288 it's pushing toward heterogeneous systems capability
290 I don't remember an include file directive for config files
291 (not filesets, actual config directives)
292 can you check the configs without starting the daemon?
293 some warnings about possible common mistakes
295 doing the testing and blessing of concurrent backup writes
296 this is absolutely necessary in the enterprise
297 easy user recovery GUI with full access checking
298 Macintosh file client
299 macs are an interesting niche, but I fear a server is a rathole
300 working bare iron recovery for windows
301 much better handling on running config changes
302 thinking through the logic of what happens to jobs in progress
303 the option for inc/diff backups not reset on fileset revision
304 a) use both change and inode update time against base time
305 b) do the full catalog check (expensive but accurate)
306 sizing guide (how much system is needed to back up N systems/files)
307 consultants on using bacula in building a disaster recovery system
309 or how to get at fancy things that one could do with bacula
310 logwatch code for bacula logs (or similar)
311 linux distro inclusion of bacula (brings good and bad, but necessary)
312 win2k/XP server capability (icky but you asked)
313 support for Oracle database ??
315 - Look at adding SQL server and Exchange support for Windows.
316 - Restore: Enter Filename: 'C:/Documents and Settings/Comercial/My
317 Documents/MOP/formulário de registro BELAS ARTES.doc' causes Bacula to
319 - Each DVD-RAM disk would be a volume, just like each tape is
320 a volume. It's a 4.7GB media with random access, but there's nothing about
321 it that I can see that makes it so different than a tape from bacula's
322 perspective. Why couldn't I back up to a bare floppy as a volume (ignoring
324 - Make dev->file and dev->block_num signed integers so that -1 can
325 be an invalid value which happens with BSR.
326 - Create VolAddr for disk files in place of VolFile and VolBlock. This
327 is needed to properly specify ranges.
328 - Print bsmtp output to job report so that problems will be seen.
329 - Pass the number of files to be restored to the FD for reporting
330 - Add progress of files/bytes to SD and FD.
331 - Don't continue Restore if no files selected.
332 - Print warning message if FileId > 4 billion
333 - do a "messages" before the first prompt in Console
334 - Add a date and time stamp at the beginning of every line in the
335 Job report (Volker Sauer).
336 - Client does not show busy during Estimate command.
337 - Implement Console mtx commands.
338 - Add a default DB password to MySQL.
339 GRANT all privileges ON bacula.* TO bacula@localhost IDENTIFIED BY
342 - Implement a Mount Command and an Unmount Command where
343 the users could specify a system command to be performed
344 to do the mount, after which Bacula could attempt to
345 read the device. This is for Removeable media such as a CDROM.
346 - Most likely, this mount command would be invoked explicitly
347 by the user using the current Console "mount" and "unmount"
348 commands -- the Storage Daemon would do the right thing
349 depending on the exact nature of the device.
350 - As with tape drives, when Bacula wanted a new removable
351 disk mounted, it would unmount the old one, and send a message
352 to the user, who would then use "mount" as described above
353 once he had actually inserted the disk.
354 - Implement dump/print label to UA
355 - Implement disk spooling. Two parts: 1. Spool to disk then
356 immediately to tape to speed up tape operations. 2. Spool to
357 disk only when the tape is full, then when a tape is hung move
359 - Scratch Pool where the volumes can be re-assigned to any Pool.
360 - bextract is sending everything to the log file ****FIXME****
361 - Add Progress command that periodically reports the progress of
363 - Restrict characters permitted in a Resource name, and don't permit
365 - Allow multiple Storage specifications (or multiple names on
366 a single Storage specification) in the Job record. Thus a job
367 can be backed up to a number of storage devices.
368 - Implement some way for the File daemon to contact the Director
369 to start a job or pass its DHCP obtained IP number.
370 - Implement multiple Consoles.
371 - Implement a query tape prompt/replace feature for a console
373 Two jobs ready to go, first one blocked waiting for media
374 Cancel 2nd job ("waiting execution" one)
377 - Copy console @ code to gnome2-console
378 - Make AES the only encryption algorithm see
379 http://csrc.nist.gov/CryptoToolkit/aes/). It's
380 an officially adopted standard, has survived peer
381 review, and provides keys up to 256 bits.
382 - Think about how space could be freed up on a tape -- perhaps this
383 is a Merge or Compact feature that is needed.
384 - Modify FileSet, did not upgrade the current Increment job, but
385 waited for the next job to be upgraded.
386 - Take a careful look at SetACL http://setacl.sourceforge.net
387 - Implement a where command for the tree telling where a file
389 - Take a careful look at Level for the estimate command, maybe make
390 it a command line option.
391 - Add Volume name to "I cannot write on this volume because"
392 - Make tree walk routines like cd, ls, ... more user friendly
393 by handling spaces better.
394 - Write your PID file and chown root:wheel before drop.
395 - Make sure there is no symlink in a file before creating a
397 - Look at mktemp or mkstemp(3).
398 mktemp and mkstemp create files with predictable names too. That's
399 not the vulnerability. The vulnerability is in creating files without
400 using the O_EXCL flag, which means "only create this file if it doesn't
401 exist, including if the file is a dangling symlink."
403 It is *NOT* enough to do the equivalent of
405 if doesn't exist $filename
406 then create $filename
408 because between the test and the create another process could have
409 gotten the CPU and created the file. You must use atomic functions
410 (those that don't get interrupted by other processes) and O_EXCL is
411 the only way for this particular example.
412 - Automatically create pools, but instead of looking for what
413 in in Job records, walk through the pool resources.
414 - Check and double check tree code, why does it take so long?
415 - Add device name to "Current Volume not acceptable because ..."
416 - Make sure that Bacula rechecks the tape after the 20 min wait.
417 - Set IO_NOWAIT on Bacula TCP/IP packets.
418 - Try doing a raw partition backup and restore by mounting a
421 Yes, it would allow to highly automatic the request for new tapes. If a
422 tape is empty, bacula reads the barcodes (native or simulated), and if
423 an unused tape is found, it runs the label command with all the
424 necessary parameters.
426 By the way can bacula automatically "move" an empty/purged volume say
427 in the "short" pool to the "long" pool if this pool runs out of volume
429 - Eliminate orphaned jobs: dbcheck, normal pruning, delete job command.
430 Hm. Well, there are the remaining orphaned job records:
432 | 105 | Llioness Save | 0000-00-00 00:00:00 | B | D | 0 | 0 | f |
433 | 110 | Llioness Save | 0000-00-00 00:00:00 | B | I | 0 | 0 | f |
434 | 115 | Llioness Save | 2003-09-10 02:22:03 | B | I | 0 | 0 | A |
435 | 128 | Catalog Save | 2003-09-11 03:53:32 | B | I | 0 | 0 | C |
436 | 131 | Catalog Save | 0000-00-00 00:00:00 | B | I | 0 | 0 | f |
438 As you can see, three of the five are failures. I already deleted the
439 one restore and one other failure using the by-client option. Deciding
440 what is an orphaned job is a tricky problem though, I agree. All these
441 records have or had 0 files/ 0 bytes, except for the restore. With no
442 files, of course, I don't know of the job ever actually becomes
443 associated with a Volume.
445 (I'm not sure if this is documented anywhere -- what are the meanings of
446 all the possible JobStatus codes?)
448 Looking at my database, it appears to me as though all the "orphaned"
449 jobs fit into one of two categories:
451 1) The Job record has a StartTime but no EndTime, and the job is not
454 2) The Job record has an EndTime, indicating that it completed, but
455 it has no associated JobMedia record.
458 This does suggest an approach. If failed jobs (or jobs that, for some
459 other reason, write no files) are associated with a volume via a
460 JobMedia record, then they should be purged when the associated volume
461 is purged. I see two ways to handle jobs that are NOT associated with a
464 1) purge them automatically whenever any volume is manually purged;
466 2) add an option to the purge command to manually purge all jobs with
467 no associated volume.
469 I think Restore jobs also fall into category 2 above .... so one might
470 want to make that "The Job record has an EndTime,, but no associated
471 JobMedia record, and is not a Restore job."
472 - make "btape /tmp" work.
473 - Make sure a rescheduled job is properly reported by status.
474 - Walk through the Pool records rather than the Job records
475 in dird.c to create/update pools.
476 - What to do about "list files job=xxx".
477 - When job rescheduled, status gives is waiting for Client Rufus
478 to connect to Storage File. Dir needs to inform SD that job
480 - Make Dmsg look at global before calling subroutine.
481 - Enable trace output at runtime for Win32
482 - Available volumes for autochangers (see patrick@baanboard.com 3 Sep 03
483 and 4 Sep) scan slots.
484 - Get and test MySQL 4.0
485 - Do a complete audit of all pthreads_mutex, cond, ... to ensure that
486 any that are dynamically initialized are destroyed when no longer used.
487 - Look at how fuser works and /proc/PID/fd that is how Nic found the
488 file descriptor leak in Bacula.
489 - Implement WrapCounters in Counters.
490 - Turn on SIGHUP in dird.c and test.
491 - Use system dependent calls to get more precise info on tape errors.
492 - Add heartbeat from FD to SD if hb interval expires.
493 - Suppress read error on blank tape when doing a label.
494 - Can we dynamically change FileSets?
495 - If pool specified to label command and Label Format is specified,
496 automatically generate the Volume name.
497 - Why can't SQL do the filename sort for restore?
498 - Look at libkse (man kse) for FreeBSD threading.
499 - Look into Microsoft Volume Shadowcopy Service VSS for backing
500 up system state components (Active Directory, System Volume, ...)
501 - Add ExhautiveRestoreSearch
502 - Look at the possibility of loading only the necessary
503 data into the restore tree (i.e. do it one directory at a
504 time as the user walks through the tree).
505 - Possibly use the hash code if the user selects all for a restore command.
506 - Orphaned Dir buffer at parse_conf.c:373 => store_dir
507 - Fix "restore all" to bypass building the tree.
508 - Prohibit backing up archive device (findlib/find_one.c:128)
509 - Implement Release Device in the Job resource to unmount a drive.
510 - Implement Acquire Device in the Job resource to mount a drive,
511 be sure this works with admin jobs so that the user can get
512 prompted to insert the correct tape. Possibly some way to say to
513 run the job but don't save the files.
514 - Implement FileOptions (see end of this document)
515 - Make things like list where a file is saved case independent for
518 - Bacula needs to propagate SD errors.

526 - Use autochanger to handle multiple devices.
527 - Add SuSE install doc to list.
528 - Check and rechedk "Invalid block number"
529 - Make bextract release the drive properly between tapes
530 so that an autochanger can be made to work.
531 - User wants to NOT backup up certain big files (email files).
532 - Maybe remove multiple simultaneous devices code in SD.
533 - On Windows with very long path names, it may be impossible to create
534 a file (and thus restore it) because the total length is too long.
535 We must cd into the directory then create the file without the
537 - lstat() is not going to work on Win32 for testing date.
538 - Implement a Recycle command
539 - Add client name to cram-md5 challenge so Director can immediately
540 verify if it is the correct client.
541 - Add JobLevel in FD status (but make sure it is defined).
542 - Audit all UA commands to ensure that we always prompt where possible.
543 - Check Jmsg in bnet, may not work, must dup bsock.
544 - Suppress Job Name in Jmsg for console
545 - Create Pools that are referenced in a Run statement at startup if possible.
546 - Use runbeforejob to unload, then reload a volume previously used,
547 then the next job run gets an error reading the drive.
548 - Make bootstrap filename unique.
549 - Test a second language e.g. french.
550 - Start working on Base jobs.
551 - Make "make binary-release" work from any directory.
552 - Implement UnsavedFiles DB record.
553 - Implement argc/argv for daemon command line scanning using table driven
555 - Implement table driven single argc/argv scanner to pickup all arguments.
556 Much like xxx_conf.c scan table.
557 keyword, handler(store_routine), store_address, code, flags, default.
558 - From Phil Stracchino:
559 It would probably be a per-client option, and would be called
560 something like, say, "Automatically purge obsoleted jobs". What it
561 would do is, when you successfully complete a Differential backup of a
562 client, it would automatically purge all Incremental backups for that
563 client that are rendered redundant by that Differential. Likewise,
564 when a Full backup on a client completed, it would automatically purge
565 all Differential and Incremental jobs obsoleted by that Full backup.
566 This would let people minimize the number of tapes they're keeping on
567 hand without having to master the art of retention times.
568 - Implement a M_SECURITY message class.
569 - When doing a Backup send all attributes back to the Director, who
570 would then figure out what files have been deleted.
571 - Currently in mount.c:236 the SD simply creates a Volume. It should have
572 explicit permission to do so. It should also mark the tape in error
573 if there is an error.
574 - Make sure all restore counters are working correctly in the FD.
575 - SD Bytes Read is wrong.
576 - Look at ALL higher level routines that call block.c to be sure
577 they don't expect something in errmsg.
578 - Investigate doing RAW backup of Win32 partition.
579 - Add thread specific data to hold the jcr -- send error messages from
580 low level routines by accessing it and using Jmsg().
581 - Cancel waiting for Client connect in SD if FD goes away.
583 - Examine Bare Metal restore problem (a FD crash exists somewhere ...).
584 - Implement timeout in response() when it should come quickly.
585 - Implement console @echo command.
586 - Implement a Slot priority (loaded/not loaded).
587 - Implement "vacation" Incremental only saves.
588 - Implement single pane restore (much like the Gftp panes).
589 - Implement Automatic Mount even in operator wait.
590 - Implement create "FileSet"?
591 - Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
592 - Implement "scratch pool" where tapes are defined and can be
593 taken by any pool that needs them.
594 - Implement restore "current system", but take all files without
595 doing selection tree -- so that jobs without File records can
597 - Add prefixlinks to where or not where absolute links to FD.
598 - Issue message to mount a new tape before the rewind.
599 - Simplified client job initiation for portables.
600 - If SD cannot open a drive, make it periodically retry.
601 - Add more of the config info to the tape label.
603 - If tape is marked read-only, then try opening it read-only rather than
604 failing, and remember that it cannot be written.
605 - Refine SD waiting output:
606 Device is being positioned
607 > Device is being positioned for append
608 > Device is being positioned to file x
610 - Figure out some way to estimate output size and to avoid splitting
611 a backup across two Volumes -- this could be useful for writing CDROMs
612 where you really prefer not to have it split -- not serious.
613 - Have SD compute MD5 or SHA1 and compare to what FD computes.
614 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
615 actual data on the Volume and compare it.
616 - Implement Bacula plugins -- design API
617 - Make bcopy read through bad tape records.
618 - Program files (i.e. execute a program to read/write files).
619 Pass read date of last backup, size of file last time.
620 - Add Signature type to File DB record.
621 - CD into subdirectory when open()ing files for backup to
622 speed up things. Test with testfind().
623 - Priority job to go to top of list.
624 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
625 - Implement some way for the Console to dynamically create a job.
626 - Restore to a particular time -- e.g. before date, after date.
627 - Solaris -I on tar for include list
628 - Need a verbose mode in restore, perhaps to bsr.
629 - bscan without -v is too quiet -- perhaps show jobs.
630 - Add code to reject whole blocks if not wanted on restore.
631 - Check if we can increase Bacula FD priorty in Win2000
632 - Make sure the MaxVolFiles is fully implemented in SD
633 - Check if both CatalogFiles and UseCatalog are set to SD.
634 - Figure out how to do a bare metal Windows restore
635 - Possibly add email to Watchdog if drive is unmounted too
636 long and a job is waiting on the drive.
637 - Restore program that errs in SD due to no tape, reports
638 OK incorrectly in output.
639 - After unmount, if restore job started, ask to mount.
640 - Convert all %x substitution variables, which are hard to remember
641 and read to %(variable-name). Idea from TMDA.
642 - Remove NextId for SQLite. Optimize.
643 - Move all SQL statements into a single location.
644 - Add UA rc and history files.
645 - put termcap (used by console) in ./configure and
646 allow -with-termcap-dir.
647 - Fix Autoprune for Volumes to respect need for full save.
648 - Fix Win32 config file definition name on /install
649 - Compare tape to Client files (attributes, or attributes and data)
650 - Make all database Ids 64 bit.
651 - Write an applet for Linux.
652 - Allow console commands to detach or run in background.
653 - Fix status delay on storage daemon during rewind.
654 - Add SD message variables to control operator wait time
655 - Maximum Operator Wait
656 - Minimum Message Interval
657 - Maximum Message Interval
658 - Send Operator message when cannot read tape label.
659 - Verify level=Volume (scan only), level=Data (compare of data to file).
660 Verify level=Catalog, level=InitCatalog
662 - Add keyword search to show command in Console.
663 - Events : tape has more than xxx bytes.
664 - Complete code in Bacula Resources -- this will permit
665 reading a new config file at any time.
666 - Handle ctl-c in Console
667 - Implement script driven addition of File daemon to config files.
668 - Think about how to make Bacula work better with File (non-tape) archives.

680 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
681 - Timout a job or terminate if link goes down, or reopen link and query.
682 - Concept of precious tapes (cannot be reused).
683 - Make bcopy copy with a single tape drive.
684 - Permit changing ownership during restore.

698 - Autolabel should be specified by DIR instead of SD.
701 - AutoScan (check checksum of tape)
702 - Format command = "format /dev/nst0"
706 - Seek resolution (usually corresponds to buffer size)
707 - EODErrorCode=ENOSPC or code
708 - Partial Read error code
709 - Partial write error code
710 - Nonformatted read error
711 - Nonformatted write error
712 - WriteProtected error
716 - IgnoreCloseErrors=yes
726 - FD sends unsaved file list to Director at end of job (see
728 - File daemon should build list of files skipped, and then
729 at end of save retry and report any errors.
730 - Write a Storage daemon that uses pipes and
731 standard Unix programs to write to the tape.
733 - Need something that monitors the JCR queue and
734 times out jobs by asking the deamons where they are.
735 - Enhance Jmsg code to permit buffering and saving to disk.
736 - device driver = "xxxx" for drives.
738 - Ensure that /dev/null works
739 - Need report class for messages. Perhaps
740 report resource where report=group of messages
741 - enhance scan_attrib and rename scan_jobtype, and
742 fill in code for "since" option
743 - Director needs a time after which the report status is sent
744 anyway -- or better yet, a retry time for the job.
745 - Don't reschedule a job if previous incarnation is still running.
746 - Some way to automatically backup everything is needed????
747 - Need a structure for pending actions:
749 - termination status (part of buffered msgs?)
751 Read, Write, Clean, Delete
752 - Login to Bacula; Bacula users with different permissions:
753 owner, group, user, quotas
754 - Store info on each file system type (probably in the job header on tape.
755 This could be the output of df; or perhaps some sort of /etc/mtab record.
758 - Design at hierarchial storage for Bacula. Migration and Clone.
759 - Implement FSM (File System Modules).
760 - Audit M_ error codes to ensure they are correct and consistent.
761 - Add variable break characters to lex analyzer.
762 Either a bit mask or a string of chars so that
763 the caller can change the break characters.
764 - Make a single T_BREAK to replace T_COMMA, etc.
765 - Ensure that File daemon and Storage daemon can
766 continue a save if the Director goes down (this
767 is NOT currently the case). Must detect socket error,
768 buffer messages for later.
769 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
770 - Add ability to backup to two Storage devices (two SD sessions) at
771 the same time -- e.g. onsite, offsite.
772 - Add the ability to consolidate old backup sets (basically do a restore
773 to tape and appropriately update the catalog). Compress Volume sets.
774 Might need to spool via file is only one drive is available.
775 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
776 someway to do so with every volume that has less than x% valid
780 Migration: Move a backup from one Volume to another
781 Clone: Copy a backup -- two Volumes
783 Bacula Migration is based on Jobs (apparently Networker is file by file).
785 Migration triggered by:
789 Highwater mark (keep total size)
794 ======================================================
796 It is somewhat like a Full save becomes an incremental since
797 the Base job (or jobs) plus other non-base files.
799 - A Base backup is same as Full backup, just different type.
800 - New BaseFiles table that contains:
802 BaseJobId - Base JobId referenced for this FileId (needed ???)
803 JobId - JobId currently running
804 FileId - File not backed up, exists in Base Job
805 FileIndex - FileIndex from Base Job.
806 i.e. for each base file that exists but is not saved because
807 it has not changed, the File daemon sends the JobId, BaseId,
808 FileId, FileIndex back to the Director who creates the DB entry.
809 - To initiate a Base save, the Director sends the FD
810 the FileId, and full filename for each file in the Base.
811 - When the FD finds a Base file, he requests the Director to
812 send him the full File entry (stat packet plus MD5), or
813 conversely, the FD sends it to the Director and the Director
814 says yes or no. This can be quite rapid if the FileId is kept
815 by the FD for each Base Filename.
816 - It is probably better to have the comparison done by the FD
817 despite the fact that the File entry must be sent across the
819 - An alternative would be to send the FD the whole File entry
820 from the start. The disadvantage is that it requires a lot of
821 space. The advantage is that it requires less communications
823 - The Job record must be updated to indicate that one or more
825 - At end of Job, FD returns:
826 1. Count of base files/bytes not written to tape (i.e. matches)
827 2. Count of base file that were saved i.e. had changed.
828 - No tape record would be written for a Base file that matches, in the
829 same way that no tape record is written for Incremental jobs where
830 the file is not saved because it is unchanged.
831 - On a restore, all the Base file records must explicitly be
832 found from the BaseFile tape. I.e. for each Full save that is marked
833 to have one or more Base Jobs, search the BaseFile for all occurrences
835 - An optimization might be to make the BaseFile have:
841 This would avoid the need to explicitly fetch each File record for
842 the Base job. The Base Job record will be fetched to get the
843 VolSessionId and VolSessionTime.
844 =========================================================
847 ==========================================================
849 For each Incremental job that is run, there may be files that
850 were found but not saved because they were locked (this applies
851 only to Windows). Such a system could send back to the Director
852 a list of Unsaved files.
854 - New UnSavedFiles table that contains:
858 - Then in the next Incremental job, the list of Unsaved Files will be
859 feed to the FD, who will ensure that they are explicitly chosen even
860 if standard date/time check would not have selected them.
861 =============================================================
864 Done: (see kernsdone for more)
867 - John's Full save failed with 1.32c FD and 1.31 Dir no FD status,
868 and no error message.
869 - Add fd and st as Console keywords.
870 - Recycling volume with a Slot requires an operator intervention:
871 rufus-dir: Start Backup JobId 18, Job=kernsave.2003-11-01_21.23.52
872 rufus-dir: Pruned 1 Job on Volume Vol01 from catalog.
873 rufus-dir: There are no Jobs associated with Volume Vol01. Marking it purged.
874 rufus-dir: Recycled volume "Vol01"
875 rufus-sd: Please mount Volume "Vol01" on Storage Device "DDS-4" for Job kernsave.2003-11-01_21.23.52
876 Use "mount" command to release Job.
877 - Implement Dan's bacula script (email of 26 Oct).
878 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
879 - Edit the Client/Storage name into authentication failure messages.
880 - Fix packet too big problem. This is most likely a Windows TCP stack
882 - Implement ClientRunBeforeJob and ClientRunAfterJob.
883 - Implement forward spacing block/file: position_device(bsr) --
884 just before read_block_from_device();

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

927 There needs to be a table of drive # to devices somewhere - If there are
928 multiple changers or drives there may not be a 1:1 correspondance between
929 changer drive number and system device name - and depending on the way the
930 drives are hooked up to scsi busses, they may not be linearly numbered
931 from an offset point either.something like
933 Autochanger drives = 2
934 Autochanger drive 0 = /dev/nst1
935 Autochanger drive 1 = /dev/nst2
936 IMHO, it would be _safest_ to use explicit mtx unload commands at all
937 times, not just for multidrive changers. For a 1 drive changer, that's
943 MTX's manpage (1.2.15):
944 unload [<slotnum>] [ <drivenum> ]
945 Unloads media from drive <drivenum> into slot
946 <slotnum>. If <drivenum> is omitted, defaults to
947 drive 0 (as do all commands). If <slotnum> is
948 omitted, defaults to the slot that the drive was
949 loaded from. Note that there's currently no way
950 to say 'unload drive 1's media to the slot it
951 came from', other than to explicitly use that
952 slot number as the destination.AB

990 Handling removable disks
992 From: Karl Cunningham <karlc@keckec.com>
994 My backups are only to hard disk these days, in removable bays. This is my
995 idea of how a backup to hard disk would work more smoothly. Some of these
996 things Bacula does already, but I mention them for completeness. If others
997 have better ways to do this, I'd like to hear about it.
999 1. Accommodate several disks, rotated similar to how tapes are. Identified
1000 by partition volume ID or perhaps by the name of a subdirectory.
1001 2. Abort & notify the admin if the wrong disk is in the bay.
1002 3. Write backups to different subdirectories for each machine to be backed
1004 4. Volumes (files) get created as needed in the proper subdirectory, one
1006 5. When a disk is recycled, remove or zero all old backup files. This is
1007 important as the disk being recycled may be close to full. This may be
1008 better done manually since the backup files for many machines may be
1009 scattered in many subdirectories.
