4 Documentation to do: (any release a little bit at a time)
5 - Document running a test version.
6 - Document query file format.
7 - Document static linking
8 - Document problems with Verify and pruning.
9 - Document how to use multiple databases.
10 - For FreeBSD typical /dev/nrsa0 and for mtx /dev/pass1
11 - VXA drives have a "cleaning required"
12 indicator, but Exabyte recommends preventive cleaning after every 75
15 In this context, it should be noted that Exabyte has a command-line
16 vxatool utility available for free download. (The current version is
17 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
18 test the drive, unload tapes, change drive settings, flash new firmware,
20 Of particular interest in this context is that vxatool <device> -i will
21 report, among other details, the time since last cleaning in tape motion
22 minutes. This information can be retrieved (and settings changed, for
23 that matter) through the generic-SCSI device even when Bacula has the
24 regular tape device locked. (Needless to say, I don't recommend
25 changing tape settings while a job is running.)
26 - Lookup HP cleaning recommendations.
27 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
28 - Create a man page for each binary (Debian package requirement).
30 Testing to do: (painful)
31 - that ALL console command line options work and are always implemented
32 - blocksize recognition code.
33 - Test if rewind at end of tape waits for tape to rewind.
35 - Test not zeroing Autochanger slot when it is wrong.
36 - Figure out how to use ssh or stunnel to protect Bacula communications.
38 For 1.33 Testing/Documentation:
39 - Document new alias records in Director. SDAddress SDDeviceName, SDPassword.
40 FDPassword, FDAddress, DBAddress, DBPort, DBPassword.
41 - Document new Include/Exclude ...
42 - Add test of exclusion, test multiple Include {} statements.
43 - Add counter variable test.
44 - Document ln -sf /usr/lib/libncurses.so /usr/lib/libtermcap.so
45 and install the esound-dev package for compiling Console on SuSE.
46 - Add an example of using a FIFO in dirdconf.wml
47 - Add an item to the FAQ about running jobs in different timezones.
48 - Add some examples of job editing codes.
49 - Add Dan's 31 Oct 2003 email on tcpwrappers to Tips.
50 - Add to supported autochangers
52 Auto-Changer : QUALSTAR TLS-4210
53 Manufufactur : Qualstar
54 Tapes : 12 (AIT1: 36GB, AIT2: 50GB all uncompressed)
55 Drives : 2xAIT2 (installed in the Qualstar: SONY SDX-500C AIT2)
56 - Setup a standard job that builds a bootstrap file and saves
57 it with the catalog database.
58 - Document Dan's new --with-dir-user, ... options.
59 - Document estimate command in tree.
60 - Document lsmark command in tree.
63 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
64 which would take precidence over the Catalog "JobRetention".
65 - Implement Label Format in Add and Label console commands.
66 - Possibly up network buffers to 65K. Put on variable.
67 - Put email tape request delays on one or more variables. User wants
68 to cancel the job after a certain time interval. Maximum Mount Wait?
69 Job, Client, Device, Pool, or Volume?
72 - Each DVD-RAM disk would be a volume, just like each tape is
73 a volume. It's a 4.7GB media with random access, but there's nothing about
74 it that I can see that makes it so different than a tape from bacula's
75 perspective. Why couldn't I back up to a bare floppy as a volume (ignoring
77 - Make dev->file and dev->block_num signed integers so that -1 can
78 be an invalid value which happens with BSR.
79 - Create VolAddr for disk files in place of VolFile and VolBlock. This
80 is needed to properly specify ranges.
81 - Print bsmtp output to job report so that problems will be seen.
82 - Pass the number of files to be restored to the FD for reporting
83 - Add progress of files/bytes to SD and FD.
84 - Don't continue Restore if no files selected.
85 - Print warning message if FileId > 4 billion
86 - do a "messages" before the first prompt in Console
87 - Add a date and time stamp at the beginning of every line in the
88 Job report (Volker Sauer).
89 - Client does not show busy during Estimate command.
90 - Implement Console mtx commands.
91 - Look at 2Gb limit for SQLite.
92 - Implement 3 Pools for a Job:
95 Full Backup Pool = xxx
96 Incremental Backup Pool = yyy
97 Differential Backup Pool = zzz
99 - Add a default DB password to MySQL.
100 GRANT all privileges ON bacula.* TO bacula@localhost IDENTIFIED BY
103 - Define week of year for scheduler. W01, W02, ...
104 Week 01 of a year is per definition the first week that has the
105 Thursday in this year, which is equivalent to the week that contains the
106 fourth day of January. In other words, the first week of a new year is
107 the week that has the majority of its days in the new year. Week 01
108 might also contain days from the previous year and the week before week
109 01 of a year is the last week (52 or 53) of the previous year even if it
110 contains days from the new year. A week starts with Monday (day 1) and
111 ends with Sunday (day 7). For example, the first week of the year 1997
112 lasts from 1996-12-30 to 1997-01-05 and can be written in standard
117 The week notation can also be extended by a number indicating the day
118 of the week. For example, the day 1996-12-31, which is the Tuesday (day
119 2) of the first week of 1997, can also be written as
121 1997-W01-2 or 1997W012
123 - Implement a Mount Command and an Unmount Command where
124 the users could specify a system command to be performed
125 to do the mount, after which Bacula could attempt to
126 read the device. This is for Removeable media such as a CDROM.
127 - Most likely, this mount command would be invoked explicitly
128 by the user using the current Console "mount" and "unmount"
129 commands -- the Storage Daemon would do the right thing
130 depending on the exact nature of the device.
131 - As with tape drives, when Bacula wanted a new removable
132 disk mounted, it would unmount the old one, and send a message
133 to the user, who would then use "mount" as described above
134 once he had actually inserted the disk.
135 - Implement dump/print label to UA
136 - Implement disk spooling. Two parts: 1. Spool to disk then
137 immediately to tape to speed up tape operations. 2. Spool to
138 disk only when the tape is full, then when a tape is hung move
140 - Scratch Pool where the volumes can be re-assigned to any Pool.
141 - bextract is sending everything to the log file ****FIXME****
142 - Add Progress command that periodically reports the progress of
144 - Restrict characters permitted in a Resource name, and don't permit
146 - Allow multiple Storage specifications (or multiple names on
147 a single Storage specification) in the Job record. Thus a job
148 can be backed up to a number of storage devices.
149 - Implement some way for the File daemon to contact the Director
150 to start a job or pass its DHCP obtained IP number.
151 - Implement multiple Consoles.
152 - Implement a query tape prompt/replace feature for a console
154 Two jobs ready to go, first one blocked waiting for media
155 Cancel 2nd job ("waiting execution" one)
158 - Copy console @ code to gnome2-console
159 - Make AES the only encryption algorithm see
160 http://csrc.nist.gov/CryptoToolkit/aes/). It's
161 an officially adopted standard, has survived peer
162 review, and provides keys up to 256 bits.
163 - Add ctl-c to console to stop current command and discard buffered
165 - Estimate to Tibs never returns.
166 - Think about how space could be freed up on a tape -- perhaps this
167 is a Merge or Compact feature that is needed.
168 - Modify FileSet, did not upgrade the current Increment job, but
169 waited for the next job to be upgraded.
170 - Take a careful look at SetACL http://setacl.sourceforge.net
171 - Implement a where command for the tree telling where a file
173 - Take a careful look at Level for the estimate command, maybe make
174 it a command line option.
175 - Add Volume name to "I cannot write on this volume because"
176 - Make restore job check if all the files are actually restored.
177 - Make tree walk routines like cd, ls, ... more user friendly
178 by handling spaces better.
179 - Write your PID file and chown root:wheel before drop.
180 - Make sure there is no symlink in a file before creating a
182 - Look at mktemp or mkstemp(3).
183 mktemp and mkstemp create files with predictable names too. That's
184 not the vulnerability. The vulnerability is in creating files without
185 using the O_EXCL flag, which means "only create this file if it doesn't
186 exist, including if the file is a dangling symlink."
188 It is *NOT* enough to do the equivalent of
190 if doesn't exist $filename
191 then create $filename
193 because between the test and the create another process could have
194 gotten the CPU and created the file. You must use atomic functions
195 (those that don't get interrupted by other processes) and O_EXCL is
196 the only way for this particular example.
197 - Automatically create pools, but instead of looking for what
198 in in Job records, walk through the pool resources.
199 - Check and double check tree code, why does it take so long?
200 - Add device name to "Current Volume not acceptable because ..."
201 - Make sure that Bacula rechecks the tape after the 20 min wait.
202 - Set IO_NOWAIT on Bacula TCP/IP packets.
203 - Try doing a raw partition backup and restore by mounting a
205 - Report CVS problems to SourceForge.
206 - Implement .consolerc for Console
208 Yes, it would allow to highly automatic the request for new tapes. If a
209 tape is empty, bacula reads the barcodes (native or simulated), and if
210 an unused tape is found, it runs the label command with all the
211 necessary parameters.
213 By the way can bacula automatically "move" an empty/purged volume say
214 in the "short" pool to the "long" pool if this pool runs out of volume
216 - Either restrict the characters in a name, or fix the problem
217 emailing with names containing / (smtp command line breaks).
218 - Eliminate orphaned jobs: dbcheck, normal pruning, delete job command.
219 Hm. Well, there are the remaining orphaned job records:
221 | 105 | Llioness Save | 0000-00-00 00:00:00 | B | D | 0 | 0 | f |
222 | 110 | Llioness Save | 0000-00-00 00:00:00 | B | I | 0 | 0 | f |
223 | 115 | Llioness Save | 2003-09-10 02:22:03 | B | I | 0 | 0 | A |
224 | 128 | Catalog Save | 2003-09-11 03:53:32 | B | I | 0 | 0 | C |
225 | 131 | Catalog Save | 0000-00-00 00:00:00 | B | I | 0 | 0 | f |
227 As you can see, three of the five are failures. I already deleted the
228 one restore and one other failure using the by-client option. Deciding
229 what is an orphaned job is a tricky problem though, I agree. All these
230 records have or had 0 files/ 0 bytes, except for the restore. With no
231 files, of course, I don't know of the job ever actually becomes
232 associated with a Volume.
234 (I'm not sure if this is documented anywhere -- what are the meanings of
235 all the possible JobStatus codes?)
237 Looking at my database, it appears to me as though all the "orphaned"
238 jobs fit into one of two categories:
240 1) The Job record has a StartTime but no EndTime, and the job is not
243 2) The Job record has an EndTime, indicating that it completed, but
244 it has no associated JobMedia record.
247 This does suggest an approach. If failed jobs (or jobs that, for some
248 other reason, write no files) are associated with a volume via a
249 JobMedia record, then they should be purged when the associated volume
250 is purged. I see two ways to handle jobs that are NOT associated with a
253 1) purge them automatically whenever any volume is manually purged;
255 2) add an option to the purge command to manually purge all jobs with
256 no associated volume.
258 I think Restore jobs also fall into category 2 above .... so one might
259 want to make that "The Job record has an EndTime,, but no associated
260 JobMedia record, and is not a Restore job."
261 - make "btape /tmp" work.
262 - Make sure a rescheduled job is properly reported by status.
263 - Walk through the Pool records rather than the Job records
264 in dird.c to create/update pools.
265 - What to do about "list files job=xxx".
266 - Implement scan: for every slot it finds, zero the slot of
267 Volume other volume having that slot.
268 - When job rescheduled, status gives is waiting for Client Rufus
269 to connect to Storage File. Dir needs to inform SD that job
271 - Fix get_storage_from_media_type (ua_restore) to use command line
273 - Don't print "Warning: Wrong Volume mounted ..." if mounting second volume.
274 - Make Dmsg look at global before calling subroutine.
275 - Enable trace output at runtime for Win32
276 - Available volumes for autochangers (see patrick@baanboard.com 3 Sep 03
277 and 4 Sep) scan slots.
278 - Get and test MySQL 4.0
279 - Do a complete audit of all pthreads_mutex, cond, ... to ensure that
280 any that are dynamically initialized are destroyed when no longer used.
281 - Write a mini-readline with history and editing.
282 - Look at how fuser works and /proc/PID/fd that is how Nic found the
283 file descriptor leak in Bacula.
284 - Implement WrapCounters in Counters.
285 - Turn on SIGHUP in dird.c and test.
286 - Use system dependent calls to get more precise info on tape errors.
287 - Add heartbeat from FD to SD if hb interval expires.
288 - Suppress read error on blank tape when doing a label.
289 - Can we dynamically change FileSets?
290 - If pool specified to label command and Label Format is specified,
291 automatically generate the Volume name.
292 - Take a careful look a the Basic recycling algorithm. When Bacula
293 chooses, the order should be:
295 - Look for Recycle or Purged
298 Instead of using lowest media Id, find the least recently used
301 When the tape is mounted and Bacula requests the status
302 - Do everything possible to use it.
304 Define a "available" status, which is the currently mounted
305 Volume and all volumes that are currently in the autochanger.
307 - Why can't SQL do the filename sort for restore?
308 - Is a pool specification really needed for a restore? Yes, and
309 you may want to exclude archive Pools.
310 - Look at libkse (man kse) for FreeBSD threading.
311 - Look into Microsoft Volume Shadowcopy Service VSS for backing
312 up system state components (Active Directory, System Volume, ...)
313 - Add ExhautiveRestoreSearch
314 - Look at the possibility of loading only the necessary
315 data into the restore tree (i.e. do it one directory at a
316 time as the user walks through the tree).
317 - Possibly use the hash code if the user selects all for a restore command.
318 - Orphaned Dir buffer at parse_conf.c:373 => store_dir
319 - Add Console usr permissions.
320 - Fix "restore all" to bypass building the tree.
321 - Fix restore to list errors if Invalid block found, and if # files
322 restored does not match # expected.
323 - Prohibit backing up archive device (findlib/find_one.c:128)
324 - Implement Release Device in the Job resource to unmount a drive.
325 - Implement Acquire Device in the Job resource to mount a drive,
326 be sure this works with admin jobs so that the user can get
327 prompted to insert the correct tape. Possibly some way to say to
328 run the job but don't save the files.
329 - Implement FileOptions (see end of this document)
330 - Make things like list where a file is saved case independent for
333 - Implement a PostgreSQL driver.
334 - Bacula needs to propagate SD errors.

342 - Use autochanger to handle multiple devices.
343 - Add SuSE install doc to list.
344 - Check and rechedk "Invalid block number"
345 - Make bextract release the drive properly between tapes
346 so that an autochanger can be made to work.
347 - User wants to NOT backup up certain big files (email files).
348 - Maybe remove multiple simultaneous devices code in SD.
349 - On Windows with very long path names, it may be impossible to create
350 a file (and thus restore it) because the total length is too long.
351 We must cd into the directory then create the file without the
353 - lstat() is not going to work on Win32 for testing date.
354 - Something is not right in last block of fill command.
355 - Implement a Recycle command
356 - Add FileSet to command line arguments for restore.
357 - Add client name to cram-md5 challenge so Director can immediately
358 verify if it is the correct client.
359 - Add JobLevel in FD status (but make sure it is defined).
360 - Audit all UA commands to ensure that we always prompt where possible.
361 - Check Jmsg in bnet, may not work, must dup bsock.
362 - Suppress Job Name in Jmsg for console
363 - Create Pools that are referenced in a Run statement at startup if possible.
364 - Use runbeforejob to unload, then reload a volume previously used,
365 then the next job run gets an error reading the drive.
366 - Make bootstrap filename unique.
367 - Test a second language e.g. french.
368 - Start working on Base jobs.
369 - Make "make binary-release" work from any directory.
370 - Implement UnsavedFiles DB record.
371 - Implement argc/argv for daemon command line scanning using table driven
373 - Implement table driven single argc/argv scanner to pickup all arguments.
374 Much like xxx_conf.c scan table.
375 keyword, handler(store_routine), store_address, code, flags, default.
376 - From Phil Stracchino:
377 It would probably be a per-client option, and would be called
378 something like, say, "Automatically purge obsoleted jobs". What it
379 would do is, when you successfully complete a Differential backup of a
380 client, it would automatically purge all Incremental backups for that
381 client that are rendered redundant by that Differential. Likewise,
382 when a Full backup on a client completed, it would automatically purge
383 all Differential and Incremental jobs obsoleted by that Full backup.
384 This would let people minimize the number of tapes they're keeping on
385 hand without having to master the art of retention times.
386 - Implement a M_SECURITY message class.
387 - When doing a Backup send all attributes back to the Director, who
388 would then figure out what files have been deleted.
389 - Currently in mount.c:236 the SD simply creates a Volume. It should have
390 explicit permission to do so. It should also mark the tape in error
391 if there is an error.
392 - Make sure all restore counters are working correctly in the FD.
393 - SD Bytes Read is wrong.
394 - Look at ALL higher level routines that call block.c to be sure
395 they don't expect something in errmsg.
396 - Investigate doing RAW backup of Win32 partition.
397 - Add thread specific data to hold the jcr -- send error messages from
398 low level routines by accessing it and using Jmsg().
399 - Cancel waiting for Client connect in SD if FD goes away.
401 - Examine Bare Metal restore problem (a FD crash exists somewhere ...).
402 - Implement timeout in response() when it should come quickly.
403 - Implement console @echo command.
404 - Implement a Slot priority (loaded/not loaded).
405 - Implement "vacation" Incremental only saves.
406 - Implement single pane restore (much like the Gftp panes).
407 - Implement Automatic Mount even in operator wait.
408 - Implement create "FileSet"?
409 - Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
410 - Implement "scratch pool" where tapes are defined and can be
411 taken by any pool that needs them.
412 - Implement restore "current system", but take all files without
413 doing selection tree -- so that jobs without File records can
415 - Implement a relocatable bacula.spec
416 - Add prefixlinks to where or not where absolute links to FD.
417 - Issue message to mount a new tape before the rewind.
418 - Simplified client job initiation for portables.
419 - If SD cannot open a drive, make it periodically retry.
420 - Add more of the config info to the tape label.
422 - If tape is marked read-only, then try opening it read-only rather than
423 failing, and remember that it cannot be written.
424 - Refine SD waiting output:
425 Device is being positioned
426 > Device is being positioned for append
427 > Device is being positioned to file x
429 - Figure out some way to estimate output size and to avoid splitting
430 a backup across two Volumes -- this could be useful for writing CDROMs
431 where you really prefer not to have it split -- not serious.
432 - Have SD compute MD5 or SHA1 and compare to what FD computes.
433 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
434 actual data on the Volume and compare it.
435 - Implement Bacula plugins -- design API
436 - Make bcopy read through bad tape records.
437 - Program files (i.e. execute a program to read/write files).
438 Pass read date of last backup, size of file last time.
439 - Add Signature type to File DB record.
440 - CD into subdirectory when open()ing files for backup to
441 speed up things. Test with testfind().
442 - Priority job to go to top of list.
443 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
444 - Implement some way for the Console to dynamically create a job.
445 - Restore to a particular time -- e.g. before date, after date.
446 - Solaris -I on tar for include list
447 - Need a verbose mode in restore, perhaps to bsr.
448 - bscan without -v is too quiet -- perhaps show jobs.
449 - Add code to reject whole blocks if not wanted on restore.
450 - Check if we can increase Bacula FD priorty in Win2000
451 - Make sure the MaxVolFiles is fully implemented in SD
452 - Check if both CatalogFiles and UseCatalog are set to SD.
453 - Figure out how to do a bare metal Windows restore
454 - Possibly add email to Watchdog if drive is unmounted too
455 long and a job is waiting on the drive.
456 - Restore program that errs in SD due to no tape, reports
457 OK incorrectly in output.
458 - After unmount, if restore job started, ask to mount.
459 - Convert all %x substitution variables, which are hard to remember
460 and read to %(variable-name). Idea from TMDA.
461 - Remove NextId for SQLite. Optimize.
462 - Move all SQL statements into a single location.
463 - Add UA rc and history files.
464 - put termcap (used by console) in ./configure and
465 allow -with-termcap-dir.
466 - Enhance time and size scanning routines.
467 - Fix Autoprune for Volumes to respect need for full save.
468 - Fix Win32 config file definition name on /install
469 - Compare tape to Client files (attributes, or attributes and data)
470 - Make all database Ids 64 bit.
471 - Write an applet for Linux.
472 - Allow console commands to detach or run in background.
473 - Fix status delay on storage daemon during rewind.
474 - Add SD message variables to control operator wait time

476 - Minimum Message Interval
477 - Maximum Message Interval
478 - Send Operator message when cannot read tape label.
479 - Verify level=Volume (scan only), level=Data (compare of data to file).
480 Verify level=Catalog, level=InitCatalog
482 - Add keyword search to show command in Console.
483 - Events : tape has more than xxx bytes.
484 - Complete code in Bacula Resources -- this will permit
485 reading a new config file at any time.
486 - Handle ctl-c in Console
487 - Implement script driven addition of File daemon to config files.
488 - Think about how to make Bacula work better with File (non-tape) archives.
489 - Write Unix emulator for Windows.
490 - Put memory utilization in Status output of each daemon
491 if full status requested or if some level of debug on.
492 - Make database type selectable by .conf files i.e. at runtime
493 - Set flag for uname -a. Add to Volume label.

501 - Timout a job or terminate if link goes down, or reopen link and query.
502 - Concept of precious tapes (cannot be reused).
503 - Make bcopy copy with a single tape drive.
504 - Permit changing ownership during restore.

550 - Autolabel should be specified by DIR instead of SD.
553 - AutoScan (check checksum of tape)
554 - Format command = "format /dev/nst0"
558 - Seek resolution (usually corresponds to buffer size)
559 - EODErrorCode=ENOSPC or code
560 - Partial Read error code
561 - Partial write error code
562 - Nonformatted read error
563 - Nonformatted write error
564 - WriteProtected error
568 - IgnoreCloseErrors=yes
578 - FD sends unsaved file list to Director at end of job (see
580 - File daemon should build list of files skipped, and then
581 at end of save retry and report any errors.
582 - Write a Storage daemon that uses pipes and
583 standard Unix programs to write to the tape.
585 - Need something that monitors the JCR queue and
586 times out jobs by asking the deamons where they are.
587 - Enhance Jmsg code to permit buffering and saving to disk.
588 - device driver = "xxxx" for drives.
590 - Ensure that /dev/null works
591 - Need report class for messages. Perhaps
592 report resource where report=group of messages
593 - enhance scan_attrib and rename scan_jobtype, and
594 fill in code for "since" option
595 - Director needs a time after which the report status is sent
596 anyway -- or better yet, a retry time for the job.
597 - Don't reschedule a job if previous incarnation is still running.
598 - Some way to automatically backup everything is needed????
599 - Need a structure for pending actions:
601 - termination status (part of buffered msgs?)
603 Read, Write, Clean, Delete
604 - Login to Bacula; Bacula users with different permissions:
605 owner, group, user, quotas
606 - Store info on each file system type (probably in the job header on tape.
607 This could be the output of df; or perhaps some sort of /etc/mtab record.
610 - Design at hierarchial storage for Bacula. Migration and Clone.
611 - Implement FSM (File System Modules).
612 - Audit M_ error codes to ensure they are correct and consistent.
613 - Add variable break characters to lex analyzer.
614 Either a bit mask or a string of chars so that
615 the caller can change the break characters.
616 - Make a single T_BREAK to replace T_COMMA, etc.
617 - Ensure that File daemon and Storage daemon can
618 continue a save if the Director goes down (this
619 is NOT currently the case). Must detect socket error,
620 buffer messages for later.
621 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
622 - Add ability to backup to two Storage devices (two SD sessions) at
623 the same time -- e.g. onsite, offsite.
624 - Add the ability to consolidate old backup sets (basically do a restore
625 to tape and appropriately update the catalog). Compress Volume sets.
626 Might need to spool via file is only one drive is available.
627 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
628 someway to do so with every volume that has less than x% valid
632 Migration: Move a backup from one Volume to another
633 Clone: Copy a backup -- two Volumes
635 Bacula Migration is based on Jobs (apparently Networker is file by file).
637 Migration triggered by:
641 Highwater mark (keep total size)
646 ======================================================
648 It is somewhat like a Full save becomes an incremental since
649 the Base job (or jobs) plus other non-base files.
651 - A Base backup is same as Full backup, just different type.
652 - New BaseFiles table that contains:
654 BaseJobId - Base JobId referenced for this FileId (needed ???)
655 JobId - JobId currently running
656 FileId - File not backed up, exists in Base Job
657 FileIndex - FileIndex from Base Job.
658 i.e. for each base file that exists but is not saved because
659 it has not changed, the File daemon sends the JobId, BaseId,
660 FileId, FileIndex back to the Director who creates the DB entry.
661 - To initiate a Base save, the Director sends the FD
662 the FileId, and full filename for each file in the Base.
663 - When the FD finds a Base file, he requests the Director to
664 send him the full File entry (stat packet plus MD5), or
665 conversely, the FD sends it to the Director and the Director
666 says yes or no. This can be quite rapid if the FileId is kept
667 by the FD for each Base Filename.
668 - It is probably better to have the comparison done by the FD
669 despite the fact that the File entry must be sent across the
671 - An alternative would be to send the FD the whole File entry
672 from the start. The disadvantage is that it requires a lot of
673 space. The advantage is that it requires less communications
675 - The Job record must be updated to indicate that one or more
677 - At end of Job, FD returns:
678 1. Count of base files/bytes not written to tape (i.e. matches)
679 2. Count of base file that were saved i.e. had changed.
680 - No tape record would be written for a Base file that matches, in the
681 same way that no tape record is written for Incremental jobs where
682 the file is not saved because it is unchanged.
683 - On a restore, all the Base file records must explicitly be
684 found from the BaseFile tape. I.e. for each Full save that is marked
685 to have one or more Base Jobs, search the BaseFile for all occurrences
687 - An optimization might be to make the BaseFile have:
693 This would avoid the need to explicitly fetch each File record for
694 the Base job. The Base Job record will be fetched to get the
695 VolSessionId and VolSessionTime.

702 Request For Comments For File Backup Options
705 Subject: File Backup Options
708 A few days ago, a Bacula user who is backing up to file volumes and
709 using compression asked if it was possible to suppress compressing
710 all .gz files since it was a waste of CPU time. Although Bacula
711 currently permits using different options (compression, ...) on
712 a directory by directory basis, it cannot do it on a file by
713 file basis, which is clearly what was desired.
715 Proposed Implementation:
716 To solve this problem, I propose the following:
718 - Add a new Director resource type called Options.
720 - The Options resource will have records for all
721 options that can currently be specified on the Include record
722 (in a FileSet). Examples below.
724 - The Options resource will permit an exclude option as well
725 as a number of additional options.
727 - The heart of the Options resource is the ability to
728 supply any number of Match records which specify POSIX
729 regular expressions. These Match regular expressions are
730 applied to the fully qualified filename (path and all). If
731 one matches, then the Options will be used.
733 - When an Match specification matches an included file, the
734 options specified in the Options resource will override
735 the default options specified on the Include record.
737 - Include records will be modified to permit referencing one or
738 more Options resources. The Options will be used
739 in the order listed on the Include record and the first
740 one that matches will be applied.
742 - Options (or specifications) currently supplied on the Include
743 record will be deprecated (i.e. removed in a later version a
744 year or so from now).
746 - The Exclude record will be deprecated as the same functionality
747 can be obtained by using an Exclude = yes in the Options.
750 The following records can appear in the Options resource. An
751 asterisk preceding the name indicates a feature not currently
754 - Regexp "xxx" - Match regular expression
755 - Wild "xxx" - Do a wild card match
758 - Compression= (GZIP, ...)
759 - Signature= (MD5, SHA1, ...)
761 - OneFs= (yes/no) - remain on one filesystem
762 - Recurse= (yes/no) - recurse into subdirectories
763 - Sparse= (yes/no) - do sparse file backup
764 - *Exclude= (yes/no) - exclude file from being saved
765 - *Reader= (filename) - external read (backup) program
766 - *Plugin= (filename) - read/write plugin module
768 - Include= (yes/no) - Include the file matched no additional
769 patterns are applied.
772 - verify= (ipnougsamc5) - verify options
775 - replace= (always/ifnewer/ifolder/never) - replace options currently
777 - *Writer= (filename) - external write (restore) program
781 Currently options specifying compression, MD5 signatures, recursion,
782 ... of a FileSet are supplied on the Include record. These will now
783 all be collected into a Options resource, which will be
784 specified in the Include in place of the options. Multiple Options
785 may be specified. Since the Options may contain regular expressions
786 that are applied to the full filename, this will give the ability
787 to specify backup options on a file by file basis to whatever level
796 Include = compression=GZIP signature=MD5 {
808 Wild = /*.?*/ # matches all files.
813 That's a lot more to do the same thing, but it gives the ability to
814 apply options on a file by file basis. For example, suppose you
815 want to compress all files but not any file with extensions .gz or .Z.
816 In that case, you will need to group two sets of options using
817 the Options resource as follows:
825 # Note multiple Matches are ORed
826 Wild = "*.gz" # matches .gz files
827 Wild = "*.Z" # matches .Z files
832 Wild = "*.?*" # matches all files
838 Now, since the no Compression option is specified in the
839 first group of Options, *.gz or *.Z file will have an MD5 signature computed,
840 but will not be compressed. For all other files, the *.gz *.Z will not
841 match, so the second group of options will be used which will include GZIP
845 - Is it necessary to provide some means of ANDing regular expressions
846 and negation? (not currently planned)
848 e.g. Wild = /*.gz/ && !/big.gz/
850 - I see that Networker has a "null" module which, if specified, does not
851 backup the file, but does make an record of the file in the catalog
852 so that the catalog will reflect an exact picture of the filesystem.
853 The result is that the file can be "seen" when "browsing" the save
854 sets, but it cannot be restored.
856 Is this really useful? Should it be implemented in Bacula?
859 After implementing the above, the user will be able to specify
860 on a file by file basis (using regular expressions) what options are
861 applied for the backup.
864 =============================================
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();
905 - Change console to bconsole.
906 - Change smtp to bsmtp.
907 - Fix time difference problem between Bacula and Client
908 so that everything is in GMT.
909 - Fix TimeZone problem!
910 - Mount a tape that is not right for the job (wrong # files on tape)
911 Bacula asks for another tape, fix problems with first tape and
912 say "mount". All works OK, but status shows:
913 Device /dev/nst0 open but no Bacula volume is mounted.
914 Total Bytes=1,153,820,213 Blocks=17,888 Bytes/block=64,502
915 Positioned at File=9 Block=3,951
916 Full Backup job Rufus.2003-10-26_16.45.31 using Volume "DLT-24Oct03" on device /dev/nst0
917 Files=21,003 Bytes=253,954,408 Bytes/sec=2,919,016
918 FDReadSeqNo=192,134 in_msg=129830 out_msg=5 fd=7
919 - Upgrade to cygwin 1.5
920 - Optimize fsf not to read.
921 - Use ioctl() fsf if it exists. Figure out where we are from
922 the mt_status command. Use slow fsf only if other does not work.
923 - Enhance "update slots" to include a "scan" feature
924 scan 1; scan 1-5; scan 1,2,4 ... to update the catalog
925 - Allow a slot or range of slots on the label barcodes command.
926 - Finish implementation of Verify=DiskToCatalog
927 - Make sure that Volumes are recycled based on "Least recently used"
928 rather than lowest MediaId.
929 - Add flag to write only one EOF mark on the tape.
930 - Implement autochanger testing in btape "test" command.
931 - Implement lmark to list everyfile marked.
932 - Make mark/unmark report how many files marked/unmarked.
933 - Keep last 5 or 10 completed jobs and show them in a similar list.
934 - Make a Running Jobs: output similar to current Scheduled Jobs:
935 - Change "create_media_record in bscan to use Archive instead of Full.
936 - Have some way to estimate the restore size or have it printed.
937 - Volume problems occurs if you have valid volume, written, then it is
938 truncated. You get 12-Nov-2003 11:48 rufus-sd: kernsave.2003-11-12_11.48.09 Warning: mount.c:228 Volume on /tmp is not a Bacula labeled Volume, because:
939 block.c:640 Read zero bytes on device /tmp.
