4 Documentation to do: (a little bit at a time)
5 - Document running a test version.
6 - Document query file format.
7 - Document static linking
8 - Document how to automatically backup all local partitions
9 - Document problems with Verify and pruning.
10 - Document how to use multiple databases.
13 Testing to do: (painful)
14 - that console command line options work
15 - blocksize recognition code.
16 - multiple simultaneous Volumes
19 - Implement max_file_size in block.c
20 - Add code if there is no mtio.h.
21 - Add a section to the doc on Manual cycling
22 - Look at purge jobs volume (at least document it, and see if it is
24 - Add list volumes pool=*
25 - Add pool= to "list media" in ua_output.c
26 - Figure out some way to specify a retention period for files
27 that no longer exist on the machine -- so that we maintain
28 say backups for 30 days, but if the file is deleted, we maintain
29 the last copy for 1 year.
30 - Have Bacula "poll" the tape to see if it is there.
31 - Add more of the config info to the tape label.
32 - Implement bar code reader for autochangers
33 - Add a default File storage so that new users can do backup
34 and restores right away.
35 - Implement a Mount Command and an Unmount Command where
36 the users could specify a system command to be performed
37 to do the mount, after which Bacula could attempt to
38 read the device. This is for Removeable media such as a
40 - Most likely, this mount command would be invoked explicitly
41 by the user using the current Console "mount" and "unmount"
42 commands -- the Storage Daemon would do the right thing
43 depending on the exact nature of the device.
44 - As with tape drives, when Bacula wanted a new removable
45 disk mounted, it would unmount the old one, and send a message
46 to the user, who would then use "mount" as described above
47 once he had actually inserted the disk.
49 - Make some way so that if a machine is skipped because it is not up
50 that Bacula will continue retrying for a specified period of time --
52 - Figure out some way to estimate output size and to avoid splitting
53 a backup across two Volumes -- this could be useful for writing CDROMs
54 where you really prefer not to have it split -- not serious.

61 - Implement Bacula plugins -- design API
62 - Make bcopy read through bad tape records.
63 - Fix read_record to handle multiple sessions.

187 - Make bcopy copy with a single tape drive.
188 - Permit changing ownership during restore.
190 - Autolabel should be specified by DIR instead of SD.
191 - Find out how to get the system tape block limits, e.g.:
192 Apr 22 21:22:10 polymatou kernel: st1: Block limits 1 - 245760 bytes.
193 Apr 22 21:22:10 polymatou kernel: st0: Block limits 2 - 16777214 bytes.
196 - AutoScan (check checksum of tape)

202 - EODErrorCode=ENOSPC or code
203 - Partial Read error code
204 - Partial write error code
205 - Nonformatted read error
206 - Nonformatted write error
207 - WriteProtected error
211 - IgnoreCloseErrors=yes
221 - FD sends unsaved file list to Director at end of job (see
223 - File daemon should build list of files skipped, and then
224 at end of save retry and report any errors.

226 standard Unix programs to write to the tape.
228 - Need something that monitors the JCR queue and
229 times out jobs by asking the deamons where they are.
230 - Enhance Jmsg code to permit buffering and saving to disk.
231 - device driver = "xxxx" for drives.
232 - restart: paranoid: read label fsf to
233 eom read append block, and go
234 super-paranoid: read label, read all files
235 in between, read append block, and go
236 verify: backspace, read append block, and go
237 permissive: same as above but frees drive
238 if tape is not valid.
240 - Ensure that /dev/null works
241 - Need report class for messages. Perhaps
242 report resource where report=group of messages
243 - enhance scan_attrib and rename scan_jobtype, and
244 fill in code for "since" option
245 - Director needs a time after which the report status is sent
246 anyway -- or better yet, a retry time for the job.
247 Don't reschedule a job if previous incarnation is still running.
248 - Some way to automatically backup everything is needed????
249 - Need a structure for pending actions:
251 - termination status (part of buffered msgs?)
252 - Concept of grouping Storage devices and job can use
253 any of a number of devices
255 Read, Write, Clean, Delete
256 - Login to Bacula; Bacula users with different permissions:
257 owner, group, user, quotas
258 - Store info on each file system type (probably in the job header on tape.
259 This could be the output of df; or perhaps some sort of /etc/mtab record.
262 - Design at hierarchial storage for Bacula.
263 - Implement FSM (File System Modules).
264 - Identify unchanged or "system" files and save them to a
265 special tape thus removing them from the standard
266 backup FileSet -- BASE backup.
267 - Turn virutally all sprintfs into snprintfs.
268 - Heartbeat between daemons.
269 - Audit M_ error codes to ensure they are correct and consistent.
270 - Add variable break characters to lex analyzer.
271 Either a bit mask or a string of chars so that
272 the caller can change the break characters.
273 - Make a single T_BREAK to replace T_COMMA, etc.
274 - Ensure that File daemon and Storage daemon can
275 continue a save if the Director goes down (this
276 is NOT currently the case). Must detect socket error,
277 buffer messages for later.
278 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
279 - Add ability to backup to two Storage devices (two SD sessions) at
280 the same time -- e.g. onsite, offsite.
281 - Add the ability to consolidate old backup sets (basically do a restore
282 to tape and appropriately update the catalog). Compress Volume sets.
283 Might need to spool via file is only one drive is available.
284 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
285 someway to do so with every volume that has less than x% valid
290 Bacula Projects Roadmap
292 last update 5 January 2003
294 Item 1: Multiple simultaneous Jobs. (done)
295 Done -- Restore part needs better implementation to work correctly
297 What: Permit multiple simultaneous jobs in Bacula.
299 Why: An enterprise level solution needs to go fast without the
300 need for the system administrator to carefully tweak
301 timing. Based on the benchmarks, during a full
302 backup, NetWorker typically hit 10 times the bandwidth to
303 the tape compared to Bacula--largely. This is probably due to
304 running parallel jobs and multi-threaded filling of buffers
305 and writing them to tape. This should also make things work
306 better when you have a mix of fast and slow machines backing
309 Notes: Bacula was designed to run multiple simultaneous jobs. Thus
310 implementing this is a matter of some small cleanups and
314 Item 2: Make the Storage daemon use intermediate file storage to buffer data.
315 Deferred -- not necessary yet.
317 What: If data is coming into the SD too fast, buffer it to
318 disk if the user has configured this option.
320 Why: This would be nice, especially if it more or less falls out
321 when implementing (1) above. If not, it probably should not
322 be given a high priority because fundamentally the backup time
323 is limited by the tape bandwidth. Even though you may finish a
324 client job quicker by spilling to disk, you still have to
325 eventually get it onto tape. If intermediate disk buffering
326 allows us to improve write bandwidth to tape, it may make
329 Notes: Whether or not this is implemented will depend upon performance
330 testing after item 1 is implemented.
333 Item 3: Write the bscan program -- also write a bcopy program.
336 What: Write a program that reads a Bacula tape and puts all the
337 appropriate data into the catalog. This allows recovery
338 from a tape that is no longer in the database, or it allows
339 re-creation of a database if lost.
341 Why: This is a fundamental robustness and disaster recovery tool
342 which will increase the comfort level of a sysadmin
343 considering adopting Bacula.
345 Notes: A skeleton of this program already exists, but much work
346 needs to be done. Implementing this will also make apparent
347 any deficiencies in the current Bacula tape format.
350 Item 4: Implement Base jobs.
352 What: A base job is sort of like a Full save except that you
353 will want the FileSet to contain only files that are unlikely
354 to change in the future (i.e. a snapshot of most of your
355 system after installing it). After the base job has been run,
356 when you are doing a Full save, you can specify to exclude
357 all files saved by the base job that have not been modified.
359 Why: This is something none of the competition does, as far as we know
360 (except BackupPC, which is a Perl program that saves to disk
361 only). It is big win for the user, it makes Bacula stand out
362 as offering a unique optimization that immediately saves time
365 Notes: Big savings in tape usage. Will require more resources because
366 the e. DIR must send FD a list of files/attribs, and the FD must
367 search the list and compare it for each file to be saved.
370 Item 5: Implement Label templates
372 What: This is a mechanism whereby Bacula can automatically create
373 a tape label for new tapes according to a detailed specification
374 provided by the user.
376 Why: It is a major convenience item for folks who use automated label
379 Notes: Bacula already has a working form of automatic tape label
380 creation, but it is very crude. The design for the complete
381 tape labeling project is already documented in the manual.
384 Item 6: Write a regression script.
387 What: This is an automatic script that runs and tests as many features
388 of Bacula as possible. The output is compared to previous
389 versions of Bacula and any differences are reported.
391 Why: This is an enormous help in preventing introduction of new
392 errors in parts of the program that already work correctly.
394 Notes: This probably should be ranked higher, it's something the typical
395 user doesn't see. Depending on how it's implemented, it may
396 make sense to defer it until the archival tape format and
397 user interface mature.
400 Item 7: GUI for interactive restore
401 Item 8: GUI for interactive backup
403 What: The current interactive restore is implemented with a tty
404 interface. It would be much nicer to be able to "see" the
405 list of files backed up in typical GUI tree format.
406 The same mechanism could also be used for creating
407 ad-hoc backup FileSets (item 8).
409 Why: Ease of use -- especially for the end user.
411 Notes: Rather than implementing in Gtk, we probably should go directly
412 for a Browser implementation, even if doing so meant the
413 capability wouldn't be available until much later. Not only
414 is there the question of Windows sites, most
415 Solaris/HP/IRIX, etc, shops can't currently run Gtk programs
416 without installing lots of stuff admins are very wary about.
417 Real sysadmins will always use the command line anyway, and
418 the user who's doing an interactive restore or backup of his
419 own files will in most cases be on a Windows machine running
423 Item 9: Add SSL to daemon communications.
425 What: This provides for secure communications between the daemons.
427 Why: This would allow doing backup across the Internet without
428 privacy concerns (or with much less concern).
430 Notes: The vast majority of near term potential users will be backing up
431 a single site over a LAN and, correctly or not, they probably
432 won't be concerned with security, at least not enough to go to
433 the trouble to set up keys, etc. to screw things down. We suspect
434 that many users genuinely interested in multi-site backup
435 already run some form of VPN software in their internetwork
436 connections, and are willing to delegate security to that layer.
439 Item 10: Define definitive tape format.
442 What: Define that definitive tape format that will not change
443 for the next millennium.
445 Why: Stability, security.
447 Notes: See notes for item 11 below.
450 Item 11: New daemon communication protocol.
452 What: The current daemon to daemon protocol is basically an ASCII
453 printf() and sending the buffer. On the receiving end, the
454 buffer is sscanf()ed to unpack it. The new scheme would
455 be a binary format that allows quick packing and unpacking
456 of any data type with named fields.
458 Why: Using binary packing would be faster. Named fields will permit
459 error checking to ensure that what is sent is what the
460 receiver really wants.
462 Notes: These are internal improvements in the interest of the
463 long-term stability and evolution of the program. On the one
464 hand, the sooner they're done, the less code we have to rip
465 up when the time comes to install them. On the other hand, they
466 don't bring an immediately perceptible benefit to potential
467 users. Item 10 and possibly item 11 should be deferred until Bacula
468 is well established with a growing user community more or
469 less happy with the feature set. At that time, it will make a
470 good "next generation" upgrade in the interest of data
476 ======================================================
478 It is somewhat like a Full save becomes an incremental since
479 the Base job (or jobs) plus other non-base files.
481 - New BaseFile table that contains:
482 JobId, BaseJobId, FileId (from Base).
483 i.e. for each base file that exists but is not saved because
484 it has not changed, the File daemon sends the JobId, BaseId,
485 and FileId back to the Director who creates the DB entry.
486 - To initiate a Base save, the Director sends the FD
487 the FileId, and full filename for each file in the Base.
488 - When the FD finds a Base file, he requests the Director to
489 send him the full File entry (stat packet plus MD5), or
490 conversely, the FD sends it to the Director and the Director
491 says yes or no. This can be quite rapid if the FileId is kept
492 by the FD for each Base Filename.
493 - It is probably better to have the comparison done by the FD
494 despite the fact that the File entry must be sent across the
496 - An alternative would be to send the FD the whole File entry
497 from the start. The disadvantage is that it requires a lot of
498 space. The advantage is that it requires less communications
500 - The Job record must be updated to indicate that one or more
502 - At end of Job, FD returns:
503 1. Count of base files/bytes not written to tape (i.e. matches)
504 2. Count of base file that were saved i.e. had changed.
505 - No tape record would be written for a Base file that matches, in the
506 same way that no tape record is written for Incremental jobs where
507 the file is not saved because it is unchanged.
508 - On a restore, all the Base file records must explicitly be
509 found from the BaseFile tape. I.e. for each Full save that is marked
510 to have one or more Base Jobs, search the BaseFile for all occurrences
512 - An optimization might be to make the BaseFile have:
518 This would avoid the need to explicitly fetch each File record for
519 the Base job. The Base Job record will be fetched to get the
520 VolSessionId and VolSessionTime.
521 =========================================================
523 ==========================================================
525 For each Incremental job that is run, there may be files that
526 were found but not saved because they were locked (this applies
527 only to Windows). Such a system could send back to the Director
528 a list of Unsaved files.
530 - New UnSavedFiles table that contains:
534 - Then in the next Incremental job, the list of Unsaved Files will be
535 feed to the FD, who will ensure that they are explicitly chosen even
536 if standard date/time check would not have selected them.
537 =============================================================
541 =============================================================
543 Request For Comments For File Backup Options
546 Subject: File Backup Options
549 A few days ago, a Bacula user who is backing up to file volumes and
550 using compression asked if it was possible to suppress compressing
551 all .gz files since it was a waste of CPU time. Although Bacula
552 currently permits using different options (compression, ...) on
553 a directory by directory basis, it cannot do it on a file by
554 file basis, which is clearly what was desired.
556 Proposed Implementation:
557 To solve this problem, I propose the following:
559 - Add a new Director resource type called FileOptions.
561 - The FileOptions resource will have records for all
562 options that can currently be specified on the Include record
563 (in a FileSet). Examples below.
565 - The FileOptions resource will permit an exclude option as well
566 as a number of additional options.
568 - The heart of the FileOptions resource is the ability to
569 supply any number of ApplyTo records which specify POSIX
570 regular expressions. These ApplyTo regular expressions are
571 applied to the fully qualified filename (path and all). If
572 one matches, then the FileOptions will be used.
574 - When an ApplyTo specification matches an included file, the
575 options specified in the FileOptions resource will override
576 the default options specified on the Include record.
578 - Include records will be modified to permit referencing one or
579 more FileOptions resources. The FileOptions will be used
580 in the order listed on the Include record and the first
581 one that matches will be applied.
583 - Options (or specifications) currently supplied on the Include
584 record will be deprecated (i.e. removed in a later version a
585 year or so from now).
587 - The Exclude record will be deprecated as the same functionality
588 can be obtained by using an Exclude = yes in the FileOptions.
591 The following records can appear in the FileOptions resource. An
592 asterisk preceding the name indicates a feature not currently
596 - Compression= (GZIP, ...)
597 - Signature= (MD5, SHA1, ...)
599 - OneFs= (yes/no) - remain on one filesystem
600 - Recurse= (yes/no) - recurse into subdirectories
601 - Sparse= (yes/no) - do sparse file backup
602 - *Exclude= (yes/no) - exclude file from being saved
603 - *Reader= (filename) - external read (backup) program
604 - *Plugin= (filename) - read/write plugin module
607 - verify= (ipnougsamc5) - verify options
610 - replace= (always/ifnewer/ifolder/never) - replace options currently
612 - *Writer= (filename) - external write (restore) program
616 Currently options specifying compression, MD5 signatures, recursion,
617 ... of a FileSet are supplied on the Include record. These will now
618 all be collected into a FileOptions resource, which will be
619 specified on the Include in place of the options. Multiple FileOptions
620 may be specified. Since the FileOptions contain regular expressions
621 that are applied to the full filename, this will give the ability
622 to specify backup options on a file by file basis to whatever level
631 Include = compression=GZIP signature=MD5 {
640 Include = FileOptions=Opts {
651 That's a lot more to do the same thing, but it gives the ability to
652 apply options on a file by file basis. For example, suppose you
653 want to compress all files but not any file with extensions .gz or .Z.
654 You could do so as follows:
658 Include = FileOptions=NoCompress FileOptions=Opts {
666 ApplyTo = /*.?*/ # matches all files
671 # Note multiple ApplyTos are ORed
672 ApplyTo = /*.gz/ # matches .gz files */
673 ApplyTo = /*.Z/ # matches .Z files */
676 Now, since the NoCompress FileOptions is specified first on the
677 Include line, any *.gz or *.Z file will have an MD5 signature computed,
678 but will not be compressed. For all other files, the NoCompress will not
679 match, so the Opts options will be used which will include GZIP
683 - Is it necessary to provide some means of ANDing regular expressions
684 and negation? (not currently planned)
686 e.g. ApplyTo = /*.gz/ && !/big.gz/
688 - I see that Networker has a "null" module which, if specified, does not
689 backup the file, but does make an record of the file in the catalog
690 so that the catalog will reflect an exact picture of the filesystem.
691 The result is that the file can be "seen" when "browsing" the save
692 sets, but it cannot be restored.
694 Is this really useful? Should it be implemented in Bacula?
697 After implementing the above, the user will be able to specify
698 on a file by file basis (using regular expressions) what options are
699 applied for the backup.

733 We have been able to get Amanda to use the HSM as a storage
734 device. Someone here wrote a driver for Amanda. BUT, Amanda doesn't
735 handle Windows systems very well (or at all without Samba). So I am
736 looking for a backup system that has a Windows client. I really like the
737 Windows integration of Bacula.
739 From the command line, its rather trivial to move the data around. We use
742 tar cf - ./files | gzip -c | rsh hsm dd of=path/file.tgz
744 or if you use GNU tar:
746 tar czf hsm:path/file.tgz ./files
748 One idea for you to consider; Sendmail offers pipes in the aliases file;
749 (mailpipe: "|/usr/bin/vacation root") and Perl supports pipes in the
750 "open" statement (open FILE, "|/bin/nroff -man";) Could you could make a
751 pipe available, as a storage device? Then we could use any command that
752 handles stdin as a storage destination.
759 #Password is not used in rsh, but might be used in ftp.
760 Device = "| gzip -c | rsh hsm dd of=path/file.tgz"
767 Password = "foobar&-"
768 Device = "| ncftpput -c hsm /path/file.bacula"

778 It is, but maybe worth a try. Is there some function in Bacula to put
779 variables in filenames? i.e. backup.2003-01-15.root

788 ==============================================
789 The Project for the above
791 I finally realized that this is not at all
792 the same as reader/writer programs or plugins,
793 which are alternate ways of accessing the
794 files to be backed up. Rather, it is an alternate
795 form of storage device, and I have always planned
796 that Bacula should be able to handle all sorts
799 So, I propose the following phases:
801 1. OK from you to invest some time in testing
802 this as I implement it (requires that you
803 know how to download from the SourceForge
804 cvs -- which I imagine is a piece of cake
807 2. Dumb implementation by allowing a device to
808 be a fifo for write only.
809 Reason: easy to implement, proof of concept.
811 3. Try reading from fifo but with fixed block
813 Reason: proof of concept, easy to implement.
815 4. Extend reading from fifo (restores) to handle
817 Reason: requires some delicate low level coding
818 which could destabilize all of Bacula.
820 5. Implementation of above but to a program. E.g.
821 Device = "|program" (not full pipeline).
822 Reason: routines already exist, and program can
823 be a shell script which contains anything.
825 6. Add full pipeline as a possibility. E.g.
826 Device = "| gzip -c | rsh hsm dd of=path/file.tgz"
827 Reason: needs additional coding to implement full
828 pipeline (must fire off either a shell or all
829 programs and connect their pipes).
831 There are a good number of details in each step
832 that I have left out, but I will specify them at
833 every stage, and there may be a few changes as things
834 evolve. I expect that to get to stage 5 will take a
835 few weeks, and at that point, you will have
836 everything you need (just inside a script).
837 Stage 6 will probably take longer, but if this
838 project pleases you, what we do for 5 should
839 be adequate for some time.
843 =============================================
845 Done: (see kernsdone for more)
846 - Look into Pruning/purging problems or why there seem to
847 be so many files listed each night.
848 - Fix cancel in find_one -- need jcr.
