9 - Document problems with Verify and pruning.
10 - Document how to use multiple databases.
11 - Document Maximum File Size
13 ***** Write up how to use/manage disk Volume Storage. ******
14 - Add a section to the doc on Manual cycling of Volumes.
15 - Document new MaximumConcurrentJob records (Job, Client, Storage)
17 Testing to do: (painful)
18 - that ALL console command line options work and are always implemented
19 - blocksize recognition code.
20 - multiple simultaneous Volumes
23 - Look at Python for a Bacula scripting language -- www.python.org
24 - add #define ENABLE_NLS for Gnome compile on SuSE.

32 - Add more of the config info to the tape label.
33 - Implement bar code reader for autochangers
34 - Add a default File storage so that new users can do backup
35 and restores right away.
36 - Implement a Mount Command and an Unmount Command where
37 the users could specify a system command to be performed
38 to do the mount, after which Bacula could attempt to
39 read the device. This is for Removeable media such as a CDROM.
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 - If tape is marked read-only, then try opening it read-only rather than
53 failing, and remember that it cannot be written.
54 - Refine SD waiting output:
55 Device is being positioned
56 > Device is being positioned for append
57 > Device is being positioned to file x
59 - Figure out some way to estimate output size and to avoid splitting
60 a backup across two Volumes -- this could be useful for writing CDROMs
61 where you really prefer not to have it split -- not serious.
62 - Add RunBeforeJob and RunAfterJob to the Client program.
63 - Have SD compute MD5 or SHA1 and compare to what FD computes.

97 - Possibly add email to Watchdog if drive is unmounted too
98 long and a job is waiting on the drive.

105 OK incorrectly in output.
106 - After unmount, if restore job started, ask to mount.

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

198 - EODErrorCode=ENOSPC or code
199 - Partial Read error code
200 - Partial write error code
201 - Nonformatted read error
202 - Nonformatted write error
203 - WriteProtected error
207 - IgnoreCloseErrors=yes
217 - FD sends unsaved file list to Director at end of job (see
219 - File daemon should build list of files skipped, and then
220 at end of save retry and report any errors.
221 - Write a Storage daemon that uses pipes and
222 standard Unix programs to write to the tape.
224 - Need something that monitors the JCR queue and
225 times out jobs by asking the deamons where they are.
226 - Enhance Jmsg code to permit buffering and saving to disk.
227 - device driver = "xxxx" for drives.
228 - restart: paranoid: read label fsf to
229 eom read append block, and go
230 super-paranoid: read label, read all files
231 in between, read append block, and go
232 verify: backspace, read append block, and go
233 permissive: same as above but frees drive
234 if tape is not valid.
236 - Ensure that /dev/null works
237 - Need report class for messages. Perhaps
238 report resource where report=group of messages
239 - enhance scan_attrib and rename scan_jobtype, and
240 fill in code for "since" option
241 - Director needs a time after which the report status is sent
242 anyway -- or better yet, a retry time for the job.
243 Don't reschedule a job if previous incarnation is still running.
244 - Some way to automatically backup everything is needed????
245 - Need a structure for pending actions:
247 - termination status (part of buffered msgs?)
248 - Concept of grouping Storage devices and job can use
249 any of a number of devices
251 Read, Write, Clean, Delete
252 - Login to Bacula; Bacula users with different permissions:
253 owner, group, user, quotas
254 - Store info on each file system type (probably in the job header on tape.
255 This could be the output of df; or perhaps some sort of /etc/mtab record.
258 - Design at hierarchial storage for Bacula. Migration and Clone.
259 - Implement FSM (File System Modules).
260 - Identify unchanged or "system" files and save them to a
261 special tape thus removing them from the standard
262 backup FileSet -- BASE backup.
263 - Turn virutally all sprintfs into snprintfs.
264 - Heartbeat between daemons.
265 - Audit M_ error codes to ensure they are correct and consistent.
266 - Add variable break characters to lex analyzer.
267 Either a bit mask or a string of chars so that
268 the caller can change the break characters.
269 - Make a single T_BREAK to replace T_COMMA, etc.
270 - Ensure that File daemon and Storage daemon can
271 continue a save if the Director goes down (this
272 is NOT currently the case). Must detect socket error,
273 buffer messages for later.
274 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
275 - Add ability to backup to two Storage devices (two SD sessions) at
276 the same time -- e.g. onsite, offsite.
277 - Add the ability to consolidate old backup sets (basically do a restore
278 to tape and appropriately update the catalog). Compress Volume sets.
279 Might need to spool via file is only one drive is available.
280 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
281 someway to do so with every volume that has less than x% valid
286 Bacula Projects Roadmap
288 last update 5 January 2003
290 Item 1: Multiple simultaneous Jobs. (done)
291 Done -- Restore part needs better implementation to work correctly
293 What: Permit multiple simultaneous jobs in Bacula.
295 Why: An enterprise level solution needs to go fast without the
296 need for the system administrator to carefully tweak
297 timing. Based on the benchmarks, during a full
298 backup, NetWorker typically hit 10 times the bandwidth to
299 the tape compared to Bacula--largely. This is probably due to
300 running parallel jobs and multi-threaded filling of buffers
301 and writing them to tape. This should also make things work
302 better when you have a mix of fast and slow machines backing
305 Notes: Bacula was designed to run multiple simultaneous jobs. Thus
306 implementing this is a matter of some small cleanups and
310 Item 2: Make the Storage daemon use intermediate file storage to buffer data.
311 Deferred -- not necessary yet.
313 What: If data is coming into the SD too fast, buffer it to
314 disk if the user has configured this option.
316 Why: This would be nice, especially if it more or less falls out
317 when implementing (1) above. If not, it probably should not
318 be given a high priority because fundamentally the backup time
319 is limited by the tape bandwidth. Even though you may finish a
320 client job quicker by spilling to disk, you still have to
321 eventually get it onto tape. If intermediate disk buffering
322 allows us to improve write bandwidth to tape, it may make
325 Notes: Whether or not this is implemented will depend upon performance
326 testing after item 1 is implemented.
329 Item 3: Write the bscan program -- also write a bcopy program.
332 What: Write a program that reads a Bacula tape and puts all the
333 appropriate data into the catalog. This allows recovery
334 from a tape that is no longer in the database, or it allows
335 re-creation of a database if lost.
337 Why: This is a fundamental robustness and disaster recovery tool
338 which will increase the comfort level of a sysadmin
339 considering adopting Bacula.
341 Notes: A skeleton of this program already exists, but much work
342 needs to be done. Implementing this will also make apparent
343 any deficiencies in the current Bacula tape format.
346 Item 4: Implement Base jobs.
348 What: A base job is sort of like a Full save except that you
349 will want the FileSet to contain only files that are unlikely
350 to change in the future (i.e. a snapshot of most of your
351 system after installing it). After the base job has been run,
352 when you are doing a Full save, you can specify to exclude
353 all files saved by the base job that have not been modified.
355 Why: This is something none of the competition does, as far as we know
356 (except BackupPC, which is a Perl program that saves to disk
357 only). It is big win for the user, it makes Bacula stand out
358 as offering a unique optimization that immediately saves time
361 Notes: Big savings in tape usage. Will require more resources because
362 the e. DIR must send FD a list of files/attribs, and the FD must
363 search the list and compare it for each file to be saved.
366 Item 5: Implement Label templates
368 What: This is a mechanism whereby Bacula can automatically create
369 a tape label for new tapes according to a detailed specification
370 provided by the user.
372 Why: It is a major convenience item for folks who use automated label
375 Notes: Bacula already has a working form of automatic tape label
376 creation, but it is very crude. The design for the complete
377 tape labeling project is already documented in the manual.
380 Item 6: Write a regression script.
383 What: This is an automatic script that runs and tests as many features
384 of Bacula as possible. The output is compared to previous
385 versions of Bacula and any differences are reported.
387 Why: This is an enormous help in preventing introduction of new
388 errors in parts of the program that already work correctly.
390 Notes: This probably should be ranked higher, it's something the typical
391 user doesn't see. Depending on how it's implemented, it may
392 make sense to defer it until the archival tape format and
393 user interface mature.
396 Item 7: GUI for interactive restore
397 Item 8: GUI for interactive backup
399 What: The current interactive restore is implemented with a tty
400 interface. It would be much nicer to be able to "see" the
401 list of files backed up in typical GUI tree format.
402 The same mechanism could also be used for creating
403 ad-hoc backup FileSets (item 8).
405 Why: Ease of use -- especially for the end user.
407 Notes: Rather than implementing in Gtk, we probably should go directly
408 for a Browser implementation, even if doing so meant the
409 capability wouldn't be available until much later. Not only
410 is there the question of Windows sites, most
411 Solaris/HP/IRIX, etc, shops can't currently run Gtk programs
412 without installing lots of stuff admins are very wary about.
413 Real sysadmins will always use the command line anyway, and
414 the user who's doing an interactive restore or backup of his
415 own files will in most cases be on a Windows machine running
419 Item 9: Add SSL to daemon communications.
421 What: This provides for secure communications between the daemons.
423 Why: This would allow doing backup across the Internet without
424 privacy concerns (or with much less concern).
426 Notes: The vast majority of near term potential users will be backing up
427 a single site over a LAN and, correctly or not, they probably
428 won't be concerned with security, at least not enough to go to
429 the trouble to set up keys, etc. to screw things down. We suspect
430 that many users genuinely interested in multi-site backup
431 already run some form of VPN software in their internetwork
432 connections, and are willing to delegate security to that layer.
435 Item 10: Define definitive tape format.
438 What: Define that definitive tape format that will not change
439 for the next millennium.
441 Why: Stability, security.
443 Notes: See notes for item 11 below.
446 Item 11: New daemon communication protocol.
448 What: The current daemon to daemon protocol is basically an ASCII
449 printf() and sending the buffer. On the receiving end, the
450 buffer is sscanf()ed to unpack it. The new scheme would
451 be a binary format that allows quick packing and unpacking
452 of any data type with named fields.
454 Why: Using binary packing would be faster. Named fields will permit
455 error checking to ensure that what is sent is what the
456 receiver really wants.
458 Notes: These are internal improvements in the interest of the
459 long-term stability and evolution of the program. On the one
460 hand, the sooner they're done, the less code we have to rip
461 up when the time comes to install them. On the other hand, they
462 don't bring an immediately perceptible benefit to potential
463 users. Item 10 and possibly item 11 should be deferred until Bacula
464 is well established with a growing user community more or
465 less happy with the feature set. At that time, it will make a
466 good "next generation" upgrade in the interest of data
472 ======================================================
474 It is somewhat like a Full save becomes an incremental since
475 the Base job (or jobs) plus other non-base files.
477 - New BaseFile table that contains:
478 JobId, BaseJobId, FileId (from Base).
479 i.e. for each base file that exists but is not saved because
480 it has not changed, the File daemon sends the JobId, BaseId,
481 and FileId back to the Director who creates the DB entry.
482 - To initiate a Base save, the Director sends the FD
483 the FileId, and full filename for each file in the Base.
484 - When the FD finds a Base file, he requests the Director to
485 send him the full File entry (stat packet plus MD5), or
486 conversely, the FD sends it to the Director and the Director
487 says yes or no. This can be quite rapid if the FileId is kept
488 by the FD for each Base Filename.
489 - It is probably better to have the comparison done by the FD
490 despite the fact that the File entry must be sent across the
492 - An alternative would be to send the FD the whole File entry
493 from the start. The disadvantage is that it requires a lot of
494 space. The advantage is that it requires less communications
496 - The Job record must be updated to indicate that one or more
498 - At end of Job, FD returns:
499 1. Count of base files/bytes not written to tape (i.e. matches)
500 2. Count of base file that were saved i.e. had changed.
501 - No tape record would be written for a Base file that matches, in the
502 same way that no tape record is written for Incremental jobs where
503 the file is not saved because it is unchanged.
504 - On a restore, all the Base file records must explicitly be
505 found from the BaseFile tape. I.e. for each Full save that is marked
506 to have one or more Base Jobs, search the BaseFile for all occurrences
508 - An optimization might be to make the BaseFile have:
514 This would avoid the need to explicitly fetch each File record for
515 the Base job. The Base Job record will be fetched to get the
516 VolSessionId and VolSessionTime.
517 =========================================================
519 ==========================================================
521 For each Incremental job that is run, there may be files that
522 were found but not saved because they were locked (this applies
523 only to Windows). Such a system could send back to the Director
524 a list of Unsaved files.
526 - New UnSavedFiles table that contains:
530 - Then in the next Incremental job, the list of Unsaved Files will be
531 feed to the FD, who will ensure that they are explicitly chosen even
532 if standard date/time check would not have selected them.
533 =============================================================
537 =============================================================
539 Request For Comments For File Backup Options
542 Subject: File Backup Options
545 A few days ago, a Bacula user who is backing up to file volumes and
546 using compression asked if it was possible to suppress compressing
547 all .gz files since it was a waste of CPU time. Although Bacula
548 currently permits using different options (compression, ...) on
549 a directory by directory basis, it cannot do it on a file by
550 file basis, which is clearly what was desired.
552 Proposed Implementation:
553 To solve this problem, I propose the following:
555 - Add a new Director resource type called FileOptions.
557 - The FileOptions resource will have records for all
558 options that can currently be specified on the Include record
559 (in a FileSet). Examples below.
561 - The FileOptions resource will permit an exclude option as well
562 as a number of additional options.
564 - The heart of the FileOptions resource is the ability to
565 supply any number of ApplyTo records which specify POSIX
566 regular expressions. These ApplyTo regular expressions are
567 applied to the fully qualified filename (path and all). If
568 one matches, then the FileOptions will be used.
570 - When an ApplyTo specification matches an included file, the
571 options specified in the FileOptions resource will override
572 the default options specified on the Include record.
574 - Include records will be modified to permit referencing one or
575 more FileOptions resources. The FileOptions will be used
576 in the order listed on the Include record and the first
577 one that matches will be applied.
579 - Options (or specifications) currently supplied on the Include
580 record will be deprecated (i.e. removed in a later version a
581 year or so from now).
583 - The Exclude record will be deprecated as the same functionality
584 can be obtained by using an Exclude = yes in the FileOptions.
587 The following records can appear in the FileOptions resource. An
588 asterisk preceding the name indicates a feature not currently
592 - Compression= (GZIP, ...)
593 - Signature= (MD5, SHA1, ...)
595 - OneFs= (yes/no) - remain on one filesystem
596 - Recurse= (yes/no) - recurse into subdirectories
597 - Sparse= (yes/no) - do sparse file backup
598 - *Exclude= (yes/no) - exclude file from being saved
599 - *Reader= (filename) - external read (backup) program
600 - *Plugin= (filename) - read/write plugin module
603 - verify= (ipnougsamc5) - verify options
606 - replace= (always/ifnewer/ifolder/never) - replace options currently
608 - *Writer= (filename) - external write (restore) program
612 Currently options specifying compression, MD5 signatures, recursion,
613 ... of a FileSet are supplied on the Include record. These will now
614 all be collected into a FileOptions resource, which will be
615 specified on the Include in place of the options. Multiple FileOptions
616 may be specified. Since the FileOptions contain regular expressions
617 that are applied to the full filename, this will give the ability
618 to specify backup options on a file by file basis to whatever level
627 Include = compression=GZIP signature=MD5 {
636 Include = FileOptions=Opts {
647 That's a lot more to do the same thing, but it gives the ability to
648 apply options on a file by file basis. For example, suppose you
649 want to compress all files but not any file with extensions .gz or .Z.
650 You could do so as follows:
654 Include = FileOptions=NoCompress FileOptions=Opts {
662 ApplyTo = /*.?*/ # matches all files
667 # Note multiple ApplyTos are ORed
668 ApplyTo = /*.gz/ # matches .gz files */
669 ApplyTo = /*.Z/ # matches .Z files */
672 Now, since the NoCompress FileOptions is specified first on the
673 Include line, any *.gz or *.Z file will have an MD5 signature computed,
674 but will not be compressed. For all other files, the NoCompress will not
675 match, so the Opts options will be used which will include GZIP
679 - Is it necessary to provide some means of ANDing regular expressions
680 and negation? (not currently planned)
682 e.g. ApplyTo = /*.gz/ && !/big.gz/
684 - I see that Networker has a "null" module which, if specified, does not
685 backup the file, but does make an record of the file in the catalog
686 so that the catalog will reflect an exact picture of the filesystem.
687 The result is that the file can be "seen" when "browsing" the save
688 sets, but it cannot be restored.
690 Is this really useful? Should it be implemented in Bacula?
693 After implementing the above, the user will be able to specify
694 on a file by file basis (using regular expressions) what options are
695 applied for the backup.

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

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

784 ==============================================
785 The Project for the above
787 I finally realized that this is not at all
788 the same as reader/writer programs or plugins,
789 which are alternate ways of accessing the
790 files to be backed up. Rather, it is an alternate
791 form of storage device, and I have always planned
792 that Bacula should be able to handle all sorts
795 So, I propose the following phases:
797 1. OK from you to invest some time in testing
798 this as I implement it (requires that you
799 know how to download from the SourceForge
800 cvs -- which I imagine is a piece of cake
803 2. Dumb implementation by allowing a device to
804 be a fifo for write only.
805 Reason: easy to implement, proof of concept.
807 3. Try reading from fifo but with fixed block
809 Reason: proof of concept, easy to implement.
811 4. Extend reading from fifo (restores) to handle
813 Reason: requires some delicate low level coding
814 which could destabilize all of Bacula.
816 5. Implementation of above but to a program. E.g.
817 Device = "|program" (not full pipeline).
818 Reason: routines already exist, and program can
819 be a shell script which contains anything.
821 6. Add full pipeline as a possibility. E.g.
822 Device = "| gzip -c | rsh hsm dd of=path/file.tgz"
823 Reason: needs additional coding to implement full
824 pipeline (must fire off either a shell or all
825 programs and connect their pipes).
827 There are a good number of details in each step
828 that I have left out, but I will specify them at
829 every stage, and there may be a few changes as things
830 evolve. I expect that to get to stage 5 will take a
831 few weeks, and at that point, you will have
832 everything you need (just inside a script).
833 Stage 6 will probably take longer, but if this
834 project pleases you, what we do for 5 should
835 be adequate for some time.
839 =============================================
841 Done: (see kernsdone for more)
842 - Look into Pruning/purging problems or why there seem to
843 be so many files listed each night.

850 - Figure out some way to automatically backup all local partitions
851 - Make hash table for linked files in findlib/find_one.c:161
853 - Rewrite find_one.c to use only pool_memory instead of
854 alloca and malloc (probably not necessary).
855 - Make sure btraceback goes into /sbin not sysconf directory.
856 - InitVerify is getting pruned and it shouldn't (document it)
857 - Make 1.28c release ??? NO do 1.29 directly
858 - Set timeout on opening fifo for save or restore (findlib)
859 - Document FIFO storage device.

864 - Restrict permissions on File Volumes (now 0640).
865 - Umasked 022 daemons
866 - Fix restore of hard linked file.
867 - Figure out how to allow multiple simultaneous file Volumes on a single device.
868 - Implement multiple simultaneous file Volumes on a single device.

877 - Implement max_file_size in block.c (already done, just tweaked).
878 - Look at purge jobs volume (at least document it, and see if it is
880 - Add list volumes does all pools. list volumes pool=xxx now works.
881 - Add pool= to "list media" in ua_output.c

883 - Fix Error: bnet.c:408 gethostbyname() for lpmatou failed:
884 ERR=Operation not permited loop.
885 - Add code if there is no mtio.h (cannot do -- too many ioctl defines needed)
886 - Produce better error messages in when error/eof writing block.
887 - Cancelling of a queued job does NOT work!!!!!!
889 rufus-dir: Volume used once. Marking Volume "File0003" as Used.
890 rufus-sd: Recycled volume File0003 on device /home/kern/bacula/working, all previous data lost.
891 rufus-dir: Volume used once. Marking Volume "File0003" as Used.
892 - Ability to backup to a file then later transfer to a tape -- Migration.
893 Migration based on MaxJobs(MinJobs),MaxVols(MinVols),AgeJobs,MaxBytes(MinBytes)
894 (i.e. HighwaterMark, LowwaterMark).
895 - Eugeny Fisher <efischer@vip-rus.com> wants to cycle through a
896 set of volumes recycling the oldest volume when it is needed.
897 - gethostbyname failure in bnet_connect() continues
898 generating errors -- should stop.
899 - Add chflags() code for FreeBSD file flags
900 - Bevan Anderson suggests having a run queue for each device
901 so that multiple simultaneous jobs can run but each writing
902 to a different Volume.
903 - Look at handling <> in smtp doesn't work with exim.
904 - Need to specify MaximumConcurrentJobs in the Job resource.
905 - ***test GetFileAttributexEx, and remove MessageBox at 335 of winservice.cpp ****
906 - Implement finer multiprocessing options.
907 - Implement | and < in Exclude statements.
908 - Figure out some way to specify a retention period for files
909 that no longer exist on the machine -- so that we maintain
910 say backups for 30 days, but if the file is deleted, we maintain
911 the last copy for 1 year. -- answer Volume retention.
