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.
11 - Add a section to the doc on Manual cycling of Volumes.
14 - Document default file backup
16 Testing to do: (painful)
17 - that ALL console command line options work and are always implemented
18 - blocksize recognition code.
19 - multiple simultaneous Volumes
22 - Fix Bare Metal restore problem.
23 - Fix "access not allowed" for backup of files on WinXP.
24 - Document new transparent Console commands and wait command.
25 - Document new immediate File save capability.
27 - Figure out how to use ssh or stunnel to protect Bacula communications.
30 - Make | and < work on FD side.
31 - Pass prefix_links to FD.
32 - Implement a M_SECURITY message class.
33 - Allow multiple Storage specifications (or multiple names on
34 a single Storage specification) in the Job record. Thus a job
35 can be backed up to a number of storage devices.
36 - Implement dump label to UA
37 - Add prefixlinks to where or not where absolute links to FD.
38 - Look at Python for a Bacula scripting language -- www.python.org
39 - Issue message to mount a new tape before the rewind.
40 - Simplified client job initiation for portables.
41 - If SD cannot open a drive, make it periodically retry.
42 - Implement LabelTemplate (at least first cut).
43 - Add more of the config info to the tape label.
44 - Implement a Mount Command and an Unmount Command where
45 the users could specify a system command to be performed
46 to do the mount, after which Bacula could attempt to
47 read the device. This is for Removeable media such as a CDROM.
48 - Most likely, this mount command would be invoked explicitly
49 by the user using the current Console "mount" and "unmount"
50 commands -- the Storage Daemon would do the right thing
51 depending on the exact nature of the device.
52 - As with tape drives, when Bacula wanted a new removable
53 disk mounted, it would unmount the old one, and send a message
54 to the user, who would then use "mount" as described above
55 once he had actually inserted the disk.
57 - Make some way so that if a machine is skipped because it is not up
58 that Bacula will continue retrying for a specified period of time --
60 - If tape is marked read-only, then try opening it read-only rather than
61 failing, and remember that it cannot be written.
62 - Refine SD waiting output:
63 Device is being positioned
64 > Device is being positioned for append
65 > Device is being positioned to file x
67 - Figure out some way to estimate output size and to avoid splitting
68 a backup across two Volumes -- this could be useful for writing CDROMs
69 where you really prefer not to have it split -- not serious.
70 - Add RunBeforeJob and RunAfterJob to the Client program.
71 - Have SD compute MD5 or SHA1 and compare to what FD computes.
72 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
73 actual data on the Volume and compare it.

75 - Implement Bacula plugins -- design API
76 - Make bcopy read through bad tape records.

80 - Add Signature type to File DB record.
81 - Make Restore report an error if FD or SD term codes are not OK.
82 - CD into subdirectory when open()ing files for backup to
83 speed up things. Test with testfind().
84 - Priority job to go to top of list.
85 - Find out why Full saves run slower and slower (hashing?)

101 a block and a record.
102 - Figure out how to do a bare metal Windows restore
103 - Put system type returned by FD into catalog.
104 - Possibly add email to Watchdog if drive is unmounted too
105 long and a job is waiting on the drive.
106 - Use read_record.c in SD code.
107 - Why don't we get an error message from Win32 FD when bootstrap
108 file cannot be created for restore command?
109 - When Marking a file in Restore that is a hard link, also
110 mark the link so that the data will be reloaded.

112 OK incorrectly in output.
113 - After unmount, if restore job started, ask to mount.
114 - Convert all %x substitution variables, which are hard to remember

179 as sprintf. Do at run time?
180 - Concept of precious tapes (cannot be reused).
181 - Make bcopy copy with a single tape drive.
182 - Permit changing ownership during restore.
184 - Autolabel should be specified by DIR instead of SD.
185 - Find out how to get the system tape block limits, e.g.:
186 Apr 22 21:22:10 polymatou kernel: st1: Block limits 1 - 245760 bytes.
187 Apr 22 21:22:10 polymatou kernel: st0: Block limits 2 - 16777214 bytes.
190 - AutoScan (check checksum of tape)

219 - Write a Storage daemon that uses pipes and
220 standard Unix programs to write to the tape.
222 - Need something that monitors the JCR queue and

225 - device driver = "xxxx" for drives.
226 - restart: paranoid: read label fsf to
227 eom read append block, and go
228 super-paranoid: read label, read all files
229 in between, read append block, and go
230 verify: backspace, read append block, and go
231 permissive: same as above but frees drive
232 if tape is not valid.
234 - Ensure that /dev/null works
235 - Need report class for messages. Perhaps
236 report resource where report=group of messages
237 - enhance scan_attrib and rename scan_jobtype, and
238 fill in code for "since" option
239 - Director needs a time after which the report status is sent
240 anyway -- or better yet, a retry time for the job.
241 Don't reschedule a job if previous incarnation is still running.
242 - Some way to automatically backup everything is needed????
243 - Need a structure for pending actions:
245 - termination status (part of buffered msgs?)
247 Read, Write, Clean, Delete
248 - Login to Bacula; Bacula users with different permissions:
249 owner, group, user, quotas
250 - Store info on each file system type (probably in the job header on tape.
251 This could be the output of df; or perhaps some sort of /etc/mtab record.
254 - Design at hierarchial storage for Bacula. Migration and Clone.
255 - Implement FSM (File System Modules).
256 - Identify unchanged or "system" files and save them to a
257 special tape thus removing them from the standard
258 backup FileSet -- BASE backup.
259 - Heartbeat between daemons.
260 - Audit M_ error codes to ensure they are correct and consistent.
261 - Add variable break characters to lex analyzer.
262 Either a bit mask or a string of chars so that
263 the caller can change the break characters.
264 - Make a single T_BREAK to replace T_COMMA, etc.
265 - Ensure that File daemon and Storage daemon can
266 continue a save if the Director goes down (this
267 is NOT currently the case). Must detect socket error,
268 buffer messages for later.
269 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
270 - Add ability to backup to two Storage devices (two SD sessions) at
271 the same time -- e.g. onsite, offsite.
272 - Add the ability to consolidate old backup sets (basically do a restore
273 to tape and appropriately update the catalog). Compress Volume sets.
274 Might need to spool via file is only one drive is available.
275 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
276 someway to do so with every volume that has less than x% valid
281 Bacula Projects Roadmap
283 last update 5 January 2003
285 Item 1: Multiple simultaneous Jobs. (done)
286 Done -- Restore part needs better implementation to work correctly
288 What: Permit multiple simultaneous jobs in Bacula.
290 Why: An enterprise level solution needs to go fast without the
291 need for the system administrator to carefully tweak
292 timing. Based on the benchmarks, during a full
293 backup, NetWorker typically hit 10 times the bandwidth to
294 the tape compared to Bacula--largely. This is probably due to
295 running parallel jobs and multi-threaded filling of buffers
296 and writing them to tape. This should also make things work
297 better when you have a mix of fast and slow machines backing
300 Notes: Bacula was designed to run multiple simultaneous jobs. Thus
301 implementing this is a matter of some small cleanups and
305 Item 2: Make the Storage daemon use intermediate file storage to buffer data.
306 Deferred -- not necessary yet.
308 What: If data is coming into the SD too fast, buffer it to
309 disk if the user has configured this option.
311 Why: This would be nice, especially if it more or less falls out
312 when implementing (1) above. If not, it probably should not
313 be given a high priority because fundamentally the backup time
314 is limited by the tape bandwidth. Even though you may finish a
315 client job quicker by spilling to disk, you still have to
316 eventually get it onto tape. If intermediate disk buffering
317 allows us to improve write bandwidth to tape, it may make
320 Notes: Whether or not this is implemented will depend upon performance
321 testing after item 1 is implemented.
324 Item 3: Write the bscan program -- also write a bcopy program.
327 What: Write a program that reads a Bacula tape and puts all the
328 appropriate data into the catalog. This allows recovery
329 from a tape that is no longer in the database, or it allows
330 re-creation of a database if lost.
332 Why: This is a fundamental robustness and disaster recovery tool
333 which will increase the comfort level of a sysadmin
334 considering adopting Bacula.
336 Notes: A skeleton of this program already exists, but much work
337 needs to be done. Implementing this will also make apparent
338 any deficiencies in the current Bacula tape format.
341 Item 4: Implement Base jobs.
343 What: A base job is sort of like a Full save except that you
344 will want the FileSet to contain only files that are unlikely
345 to change in the future (i.e. a snapshot of most of your
346 system after installing it). After the base job has been run,
347 when you are doing a Full save, you can specify to exclude
348 all files saved by the base job that have not been modified.
350 Why: This is something none of the competition does, as far as we know
351 (except BackupPC, which is a Perl program that saves to disk
352 only). It is big win for the user, it makes Bacula stand out
353 as offering a unique optimization that immediately saves time
356 Notes: Big savings in tape usage. Will require more resources because
357 the e. DIR must send FD a list of files/attribs, and the FD must
358 search the list and compare it for each file to be saved.
361 Item 5: Implement Label templates
363 What: This is a mechanism whereby Bacula can automatically create
364 a tape label for new tapes according to a detailed specification
365 provided by the user.
367 Why: It is a major convenience item for folks who use automated label
370 Notes: Bacula already has a working form of automatic tape label
371 creation, but it is very crude. The design for the complete
372 tape labeling project is already documented in the manual.
375 Item 6: Write a regression script.
378 What: This is an automatic script that runs and tests as many features
379 of Bacula as possible. The output is compared to previous
380 versions of Bacula and any differences are reported.
382 Why: This is an enormous help in preventing introduction of new
383 errors in parts of the program that already work correctly.
385 Notes: This probably should be ranked higher, it's something the typical
386 user doesn't see. Depending on how it's implemented, it may
387 make sense to defer it until the archival tape format and
388 user interface mature.
391 Item 7: GUI for interactive restore
392 Item 8: GUI for interactive backup
394 What: The current interactive restore is implemented with a tty
395 interface. It would be much nicer to be able to "see" the
396 list of files backed up in typical GUI tree format.
397 The same mechanism could also be used for creating
398 ad-hoc backup FileSets (item 8).
400 Why: Ease of use -- especially for the end user.
402 Notes: Rather than implementing in Gtk, we probably should go directly
403 for a Browser implementation, even if doing so meant the
404 capability wouldn't be available until much later. Not only
405 is there the question of Windows sites, most
406 Solaris/HP/IRIX, etc, shops can't currently run Gtk programs
407 without installing lots of stuff admins are very wary about.
408 Real sysadmins will always use the command line anyway, and
409 the user who's doing an interactive restore or backup of his
410 own files will in most cases be on a Windows machine running
414 Item 9: Add SSL to daemon communications.
416 What: This provides for secure communications between the daemons.
418 Why: This would allow doing backup across the Internet without
419 privacy concerns (or with much less concern).
421 Notes: The vast majority of near term potential users will be backing up
422 a single site over a LAN and, correctly or not, they probably
423 won't be concerned with security, at least not enough to go to
424 the trouble to set up keys, etc. to screw things down. We suspect
425 that many users genuinely interested in multi-site backup
426 already run some form of VPN software in their internetwork
427 connections, and are willing to delegate security to that layer.
430 Item 10: Define definitive tape format.
433 What: Define that definitive tape format that will not change
434 for the next millennium.
436 Why: Stability, security.
438 Notes: See notes for item 11 below.
441 Item 11: New daemon communication protocol.
443 What: The current daemon to daemon protocol is basically an ASCII
444 printf() and sending the buffer. On the receiving end, the
445 buffer is sscanf()ed to unpack it. The new scheme would
446 be a binary format that allows quick packing and unpacking
447 of any data type with named fields.
449 Why: Using binary packing would be faster. Named fields will permit
450 error checking to ensure that what is sent is what the
451 receiver really wants.
453 Notes: These are internal improvements in the interest of the
454 long-term stability and evolution of the program. On the one
455 hand, the sooner they're done, the less code we have to rip
456 up when the time comes to install them. On the other hand, they
457 don't bring an immediately perceptible benefit to potential
458 users. Item 10 and possibly item 11 should be deferred until Bacula
459 is well established with a growing user community more or
460 less happy with the feature set. At that time, it will make a
461 good "next generation" upgrade in the interest of data
467 ======================================================
469 It is somewhat like a Full save becomes an incremental since
470 the Base job (or jobs) plus other non-base files.
472 - New BaseFile table that contains:
473 JobId, BaseJobId, FileId (from Base).
474 i.e. for each base file that exists but is not saved because
475 it has not changed, the File daemon sends the JobId, BaseId,
476 and FileId back to the Director who creates the DB entry.
477 - To initiate a Base save, the Director sends the FD
478 the FileId, and full filename for each file in the Base.
479 - When the FD finds a Base file, he requests the Director to
480 send him the full File entry (stat packet plus MD5), or
481 conversely, the FD sends it to the Director and the Director
482 says yes or no. This can be quite rapid if the FileId is kept
483 by the FD for each Base Filename.
484 - It is probably better to have the comparison done by the FD
485 despite the fact that the File entry must be sent across the
487 - An alternative would be to send the FD the whole File entry
488 from the start. The disadvantage is that it requires a lot of
489 space. The advantage is that it requires less communications
491 - The Job record must be updated to indicate that one or more
493 - At end of Job, FD returns:
494 1. Count of base files/bytes not written to tape (i.e. matches)
495 2. Count of base file that were saved i.e. had changed.
496 - No tape record would be written for a Base file that matches, in the
497 same way that no tape record is written for Incremental jobs where
498 the file is not saved because it is unchanged.
499 - On a restore, all the Base file records must explicitly be
500 found from the BaseFile tape. I.e. for each Full save that is marked
501 to have one or more Base Jobs, search the BaseFile for all occurrences
503 - An optimization might be to make the BaseFile have:
509 This would avoid the need to explicitly fetch each File record for
510 the Base job. The Base Job record will be fetched to get the
511 VolSessionId and VolSessionTime.
512 =========================================================
514 ==========================================================
516 For each Incremental job that is run, there may be files that
517 were found but not saved because they were locked (this applies
518 only to Windows). Such a system could send back to the Director
519 a list of Unsaved files.
521 - New UnSavedFiles table that contains:
525 - Then in the next Incremental job, the list of Unsaved Files will be
526 feed to the FD, who will ensure that they are explicitly chosen even
527 if standard date/time check would not have selected them.
528 =============================================================
532 =============================================================
534 Request For Comments For File Backup Options
537 Subject: File Backup Options
540 A few days ago, a Bacula user who is backing up to file volumes and
541 using compression asked if it was possible to suppress compressing
542 all .gz files since it was a waste of CPU time. Although Bacula
543 currently permits using different options (compression, ...) on
544 a directory by directory basis, it cannot do it on a file by
545 file basis, which is clearly what was desired.
547 Proposed Implementation:
548 To solve this problem, I propose the following:
550 - Add a new Director resource type called FileOptions.
552 - The FileOptions resource will have records for all
553 options that can currently be specified on the Include record
554 (in a FileSet). Examples below.
556 - The FileOptions resource will permit an exclude option as well
557 as a number of additional options.
559 - The heart of the FileOptions resource is the ability to
560 supply any number of ApplyTo records which specify POSIX
561 regular expressions. These ApplyTo regular expressions are
562 applied to the fully qualified filename (path and all). If
563 one matches, then the FileOptions will be used.
565 - When an ApplyTo specification matches an included file, the
566 options specified in the FileOptions resource will override
567 the default options specified on the Include record.
569 - Include records will be modified to permit referencing one or
570 more FileOptions resources. The FileOptions will be used
571 in the order listed on the Include record and the first
572 one that matches will be applied.
574 - Options (or specifications) currently supplied on the Include
575 record will be deprecated (i.e. removed in a later version a
576 year or so from now).
578 - The Exclude record will be deprecated as the same functionality
579 can be obtained by using an Exclude = yes in the FileOptions.
582 The following records can appear in the FileOptions resource. An
583 asterisk preceding the name indicates a feature not currently
587 - Compression= (GZIP, ...)
588 - Signature= (MD5, SHA1, ...)
590 - OneFs= (yes/no) - remain on one filesystem
591 - Recurse= (yes/no) - recurse into subdirectories
592 - Sparse= (yes/no) - do sparse file backup
593 - *Exclude= (yes/no) - exclude file from being saved
594 - *Reader= (filename) - external read (backup) program
595 - *Plugin= (filename) - read/write plugin module
598 - verify= (ipnougsamc5) - verify options
601 - replace= (always/ifnewer/ifolder/never) - replace options currently
603 - *Writer= (filename) - external write (restore) program
607 Currently options specifying compression, MD5 signatures, recursion,
608 ... of a FileSet are supplied on the Include record. These will now
609 all be collected into a FileOptions resource, which will be
610 specified on the Include in place of the options. Multiple FileOptions
611 may be specified. Since the FileOptions contain regular expressions
612 that are applied to the full filename, this will give the ability
613 to specify backup options on a file by file basis to whatever level
622 Include = compression=GZIP signature=MD5 {
631 Include = FileOptions=Opts {
642 That's a lot more to do the same thing, but it gives the ability to
643 apply options on a file by file basis. For example, suppose you
644 want to compress all files but not any file with extensions .gz or .Z.
645 You could do so as follows:
649 Include = FileOptions=NoCompress FileOptions=Opts {
657 ApplyTo = /*.?*/ # matches all files
662 # Note multiple ApplyTos are ORed
663 ApplyTo = /*.gz/ # matches .gz files */
664 ApplyTo = /*.Z/ # matches .Z files */
667 Now, since the NoCompress FileOptions is specified first on the
668 Include line, any *.gz or *.Z file will have an MD5 signature computed,
669 but will not be compressed. For all other files, the NoCompress will not
670 match, so the Opts options will be used which will include GZIP
674 - Is it necessary to provide some means of ANDing regular expressions
675 and negation? (not currently planned)
677 e.g. ApplyTo = /*.gz/ && !/big.gz/
679 - I see that Networker has a "null" module which, if specified, does not
680 backup the file, but does make an record of the file in the catalog
681 so that the catalog will reflect an exact picture of the filesystem.
682 The result is that the file can be "seen" when "browsing" the save
683 sets, but it cannot be restored.
685 Is this really useful? Should it be implemented in Bacula?
688 After implementing the above, the user will be able to specify
689 on a file by file basis (using regular expressions) what options are
690 applied for the backup.

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

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

779 ==============================================
780 The Project for the above
782 I finally realized that this is not at all
783 the same as reader/writer programs or plugins,
784 which are alternate ways of accessing the
785 files to be backed up. Rather, it is an alternate
786 form of storage device, and I have always planned
787 that Bacula should be able to handle all sorts
790 So, I propose the following phases:
792 1. OK from you to invest some time in testing
793 this as I implement it (requires that you
794 know how to download from the SourceForge
795 cvs -- which I imagine is a piece of cake
798 2. Dumb implementation by allowing a device to
799 be a fifo for write only.
800 Reason: easy to implement, proof of concept.
802 3. Try reading from fifo but with fixed block
804 Reason: proof of concept, easy to implement.
806 4. Extend reading from fifo (restores) to handle
808 Reason: requires some delicate low level coding
809 which could destabilize all of Bacula.
811 5. Implementation of above but to a program. E.g.
812 Device = "|program" (not full pipeline).
813 Reason: routines already exist, and program can
814 be a shell script which contains anything.
816 6. Add full pipeline as a possibility. E.g.
817 Device = "| gzip -c | rsh hsm dd of=path/file.tgz"
818 Reason: needs additional coding to implement full
819 pipeline (must fire off either a shell or all
820 programs and connect their pipes).
822 There are a good number of details in each step
823 that I have left out, but I will specify them at
824 every stage, and there may be a few changes as things
825 evolve. I expect that to get to stage 5 will take a
826 few weeks, and at that point, you will have
827 everything you need (just inside a script).
828 Stage 6 will probably take longer, but if this
829 project pleases you, what we do for 5 should
830 be adequate for some time.
