63 - Implement disk spooling. Two parts: 1. Spool to disk then

65 disk only when the tape is full, then when a tape is hung move
67 - From Phil Stracchino:
68 It would probably be a per-client option, and would be called
69 something like, say, "Automatically purge obsoleted jobs". What it
70 would do is, when you successfully complete a Differential backup of a
71 client, it would automatically purge all Incremental backups for that
72 client that are rendered redundant by that Differential. Likewise,
73 when a Full backup on a client completed, it would automatically purge
74 all Differential and Incremental jobs obsoleted by that Full backup.
75 This would let people minimize the number of tapes they're keeping on
76 hand without having to master the art of retention times.
78 - Allow multiple Storage specifications (or multiple names on
79 a single Storage specification) in the Job record. Thus a job
80 can be backed up to a number of storage devices.
81 - Implement dump/print label to UA
82 - Add prefixlinks to where or not where absolute links to FD.
83 - Look at Python for a Bacula scripting language -- www.python.org
84 - Issue message to mount a new tape before the rewind.
85 - Simplified client job initiation for portables.
86 - If SD cannot open a drive, make it periodically retry.
87 - Implement LabelTemplate (at least first cut).
88 - Add more of the config info to the tape label.
89 - Implement a Mount Command and an Unmount Command where
90 the users could specify a system command to be performed
91 to do the mount, after which Bacula could attempt to
92 read the device. This is for Removeable media such as a CDROM.
93 - Most likely, this mount command would be invoked explicitly
94 by the user using the current Console "mount" and "unmount"
95 commands -- the Storage Daemon would do the right thing
96 depending on the exact nature of the device.
97 - As with tape drives, when Bacula wanted a new removable
98 disk mounted, it would unmount the old one, and send a message
99 to the user, who would then use "mount" as described above
100 once he had actually inserted the disk.
102 - Make some way so that if a machine is skipped because it is not up
103 that Bacula will continue retrying for a specified period of time --
105 - If tape is marked read-only, then try opening it read-only rather than
106 failing, and remember that it cannot be written.
107 - Refine SD waiting output:
108 Device is being positioned
109 > Device is being positioned for append
110 > Device is being positioned to file x
112 - Figure out some way to estimate output size and to avoid splitting
113 a backup across two Volumes -- this could be useful for writing CDROMs
114 where you really prefer not to have it split -- not serious.
115 - Add RunBeforeJob and RunAfterJob to the Client program.
116 - Have SD compute MD5 or SHA1 and compare to what FD computes.
117 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
118 actual data on the Volume and compare it.
119 - Implement FileOptions (see end of this document)
120 - Implement Bacula plugins -- design API
121 - Make bcopy read through bad tape records.
122 - Fix read_record to handle multiple sessions.

124 Pass read date of last backup, size of file last time.
125 - Add Signature type to File DB record.
126 - Make Restore report an error if FD or SD term codes are not OK.
127 - CD into subdirectory when open()ing files for backup to
128 speed up things. Test with testfind().
129 - Priority job to go to top of list.
130 - Find out why Full saves run slower and slower (hashing?)
131 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
132 - Implement some way for the Console to dynamically create a job.
133 - Restore to a particular time -- e.g. before date, after date.
134 - Solaris -I on tar for include list
135 - Prohibit backing up archive device (findlib/find_one.c:128)
136 - Need a verbose mode in restore, perhaps to bsr.

138 - Add code to reject whole blocks if not wanted on restore.
139 - Start working on Base jobs.
140 - Check if we can increase Bacula FD priorty in Win2000
141 - Make sure the MaxVolFiles is fully implemented in SD
142 - Check if both CatalogFiles and UseCatalog are set to SD.
143 - Need return status on read_cb() from read_records(). Need multiple
144 records -- one per Job, maybe a JCR or some other structure with
145 a block and a record.
146 - Figure out how to do a bare metal Windows restore
147 - Put system type returned by FD into catalog.
148 - Possibly add email to Watchdog if drive is unmounted too
149 long and a job is waiting on the drive.
150 - Use read_record.c in SD code.
151 - Why don't we get an error message from Win32 FD when bootstrap
152 file cannot be created for restore command?
153 - When Marking a file in Restore that is a hard link, also
154 mark the link so that the data will be reloaded.
155 - Restore program that errors in SD due to no tape reports
156 OK incorrectly in output.
157 - After unmount, if restore job started, ask to mount.
158 - Convert all %x substitution variables, which are hard to remember
159 and read to %(variable-name). Idea from TMDA.
160 - Add JobLevel in FD status (but make sure it is defined).
161 - Make Pool resource handle Counter resources.
162 - Remove NextId for SQLite. Optimize.

224 - Concept of precious tapes (cannot be reused).
225 - Make bcopy copy with a single tape drive.
226 - Permit changing ownership during restore.
228 - Autolabel should be specified by DIR instead of SD.
229 - Find out how to get the system tape block limits, e.g.:
230 Apr 22 21:22:10 polymatou kernel: st1: Block limits 1 - 245760 bytes.
231 Apr 22 21:22:10 polymatou kernel: st0: Block limits 2 - 16777214 bytes.
234 - AutoScan (check checksum of tape)

249 - IgnoreCloseErrors=yes
259 - FD sends unsaved file list to Director at end of job (see

274 verify: backspace, read append block, and go
275 permissive: same as above but frees drive
276 if tape is not valid.
278 - Ensure that /dev/null works
279 - Need report class for messages. Perhaps
280 report resource where report=group of messages
281 - enhance scan_attrib and rename scan_jobtype, and
282 fill in code for "since" option
283 - Director needs a time after which the report status is sent
284 anyway -- or better yet, a retry time for the job.
285 Don't reschedule a job if previous incarnation is still running.
286 - Some way to automatically backup everything is needed????
287 - Need a structure for pending actions:
289 - termination status (part of buffered msgs?)
291 Read, Write, Clean, Delete
292 - Login to Bacula; Bacula users with different permissions:
293 owner, group, user, quotas
294 - Store info on each file system type (probably in the job header on tape.
295 This could be the output of df; or perhaps some sort of /etc/mtab record.
298 - Design at hierarchial storage for Bacula. Migration and Clone.
299 - Implement FSM (File System Modules).
300 - Identify unchanged or "system" files and save them to a
301 special tape thus removing them from the standard
302 backup FileSet -- BASE backup.
303 - Audit M_ error codes to ensure they are correct and consistent.
304 - Add variable break characters to lex analyzer.
305 Either a bit mask or a string of chars so that
306 the caller can change the break characters.
307 - Make a single T_BREAK to replace T_COMMA, etc.
308 - Ensure that File daemon and Storage daemon can
309 continue a save if the Director goes down (this
310 is NOT currently the case). Must detect socket error,
311 buffer messages for later.
312 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
313 - Add ability to backup to two Storage devices (two SD sessions) at
314 the same time -- e.g. onsite, offsite.
315 - Add the ability to consolidate old backup sets (basically do a restore
316 to tape and appropriately update the catalog). Compress Volume sets.
317 Might need to spool via file is only one drive is available.
318 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
319 someway to do so with every volume that has less than x% valid
324 Bacula Projects Roadmap
326 last update 8 May 2003
328 Item 1: Multiple simultaneous Jobs. (done)
329 Done -- Restore part needs better implementation to work correctly
330 Also, it needs considerable testing
332 What: Permit multiple simultaneous jobs in Bacula.
334 Why: An enterprise level solution needs to go fast without the
335 need for the system administrator to carefully tweak
336 timing. Based on the benchmarks, during a full
337 backup, NetWorker typically hit 10 times the bandwidth to
338 the tape compared to Bacula--largely. This is probably due to
339 running parallel jobs and multi-threaded filling of buffers
340 and writing them to tape. This should also make things work
341 better when you have a mix of fast and slow machines backing
344 Notes: Bacula was designed to run multiple simultaneous jobs. Thus
345 implementing this is a matter of some small cleanups and
349 Item 2: Make the Storage daemon use intermediate file storage to buffer data.
350 Deferred -- not necessary yet.
352 What: If data is coming into the SD too fast, buffer it to
353 disk if the user has configured this option.
355 Why: This would be nice, especially if it more or less falls out
356 when implementing (1) above. If not, it probably should not
357 be given a high priority because fundamentally the backup time
358 is limited by the tape bandwidth. Even though you may finish a
359 client job quicker by spilling to disk, you still have to
360 eventually get it onto tape. If intermediate disk buffering
361 allows us to improve write bandwidth to tape, it may make
364 Notes: Whether or not this is implemented will depend upon performance
365 testing after item 1 is implemented.
368 Item 3: Write the bscan program -- also write a bcopy program.
371 What: Write a program that reads a Bacula tape and puts all the
372 appropriate data into the catalog. This allows recovery
373 from a tape that is no longer in the database, or it allows
374 re-creation of a database if lost.
376 Why: This is a fundamental robustness and disaster recovery tool
377 which will increase the comfort level of a sysadmin
378 considering adopting Bacula.
380 Notes: A skeleton of this program already exists, but much work
381 needs to be done. Implementing this will also make apparent
382 any deficiencies in the current Bacula tape format.
385 Item 4: Implement Base jobs.
387 What: A base job is sort of like a Full save except that you
388 will want the FileSet to contain only files that are unlikely
389 to change in the future (i.e. a snapshot of most of your
390 system after installing it). After the base job has been run,
391 when you are doing a Full save, you can specify to exclude
392 all files saved by the base job that have not been modified.
394 Why: This is something none of the competition does, as far as we know
395 (except BackupPC, which is a Perl program that saves to disk
396 only). It is big win for the user, it makes Bacula stand out
397 as offering a unique optimization that immediately saves time
400 Notes: Big savings in tape usage. Will require more resources because
401 the e. DIR must send FD a list of files/attribs, and the FD must
402 search the list and compare it for each file to be saved.
405 Item 5: Implement Label templates
407 What: This is a mechanism whereby Bacula can automatically create
408 a tape label for new tapes according to a detailed specification
409 provided by the user.
411 Why: It is a major convenience item for folks who use automated label
414 Notes: Bacula already has a working form of automatic tape label
415 creation, but it is very crude. The design for the complete
416 tape labeling project is already documented in the manual.
419 Item 6: Write a regression script.
420 Done -- Continue to expand its testing.
422 What: This is an automatic script that runs and tests as many features
423 of Bacula as possible. The output is compared to previous
424 versions of Bacula and any differences are reported.
426 Why: This is an enormous help in preventing introduction of new
427 errors in parts of the program that already work correctly.
429 Notes: This probably should be ranked higher, it's something the typical
430 user doesn't see. Depending on how it's implemented, it may
431 make sense to defer it until the archival tape format and
432 user interface mature.
435 Item 7: GUI for interactive restore
436 Item 8: GUI for interactive backup
438 What: The current interactive restore is implemented with a tty
439 interface. It would be much nicer to be able to "see" the
440 list of files backed up in typical GUI tree format.
441 The same mechanism could also be used for creating
442 ad-hoc backup FileSets (item 8).
444 Why: Ease of use -- especially for the end user.
446 Notes: Rather than implementing in Gtk, we probably should go directly
447 for a Browser implementation, even if doing so meant the
448 capability wouldn't be available until much later. Not only
449 is there the question of Windows sites, most
450 Solaris/HP/IRIX, etc, shops can't currently run Gtk programs
451 without installing lots of stuff admins are very wary about.
452 Real sysadmins will always use the command line anyway, and
453 the user who's doing an interactive restore or backup of his
454 own files will in most cases be on a Windows machine running
458 Item 9: Add SSL to daemon communications.
459 Inprogress as of version 1.31.
461 What: This provides for secure communications between the daemons.
463 Why: This would allow doing backup across the Internet without
464 privacy concerns (or with much less concern).
466 Notes: The vast majority of near term potential users will be backing up
467 a single site over a LAN and, correctly or not, they probably
468 won't be concerned with security, at least not enough to go to
469 the trouble to set up keys, etc. to screw things down. We suspect
470 that many users genuinely interested in multi-site backup
471 already run some form of VPN software in their internetwork
472 connections, and are willing to delegate security to that layer.
475 Item 10: Define definitive tape format.
478 What: Define that definitive tape format that will not change
479 for the next millennium.
481 Why: Stability, security.
483 Notes: See notes for item 11 below.
486 Item 11: New daemon communication protocol.
488 What: The current daemon to daemon protocol is basically an ASCII
489 printf() and sending the buffer. On the receiving end, the
490 buffer is sscanf()ed to unpack it. The new scheme would
491 be a binary format that allows quick packing and unpacking
492 of any data type with named fields.
494 Why: Using binary packing would be faster. Named fields will permit
495 error checking to ensure that what is sent is what the
496 receiver really wants.
498 Notes: These are internal improvements in the interest of the
499 long-term stability and evolution of the program. On the one
500 hand, the sooner they're done, the less code we have to rip
501 up when the time comes to install them. On the other hand, they
502 don't bring an immediately perceptible benefit to potential
503 users. Item 10 and possibly item 11 should be deferred until Bacula
504 is well established with a growing user community more or
505 less happy with the feature set. At that time, it will make a
506 good "next generation" upgrade in the interest of data
512 ======================================================
514 It is somewhat like a Full save becomes an incremental since
515 the Base job (or jobs) plus other non-base files.
517 - New BaseFile table that contains:
518 JobId, BaseJobId, FileId (from Base).
519 i.e. for each base file that exists but is not saved because
520 it has not changed, the File daemon sends the JobId, BaseId,
521 and FileId back to the Director who creates the DB entry.
522 - To initiate a Base save, the Director sends the FD
523 the FileId, and full filename for each file in the Base.
524 - When the FD finds a Base file, he requests the Director to
525 send him the full File entry (stat packet plus MD5), or
526 conversely, the FD sends it to the Director and the Director
527 says yes or no. This can be quite rapid if the FileId is kept
528 by the FD for each Base Filename.
529 - It is probably better to have the comparison done by the FD
530 despite the fact that the File entry must be sent across the
532 - An alternative would be to send the FD the whole File entry
533 from the start. The disadvantage is that it requires a lot of
534 space. The advantage is that it requires less communications
536 - The Job record must be updated to indicate that one or more
538 - At end of Job, FD returns:
539 1. Count of base files/bytes not written to tape (i.e. matches)
540 2. Count of base file that were saved i.e. had changed.
541 - No tape record would be written for a Base file that matches, in the
542 same way that no tape record is written for Incremental jobs where
543 the file is not saved because it is unchanged.
544 - On a restore, all the Base file records must explicitly be
545 found from the BaseFile tape. I.e. for each Full save that is marked
546 to have one or more Base Jobs, search the BaseFile for all occurrences
548 - An optimization might be to make the BaseFile have:
554 This would avoid the need to explicitly fetch each File record for
555 the Base job. The Base Job record will be fetched to get the
556 VolSessionId and VolSessionTime.

563 Request For Comments For File Backup Options
566 Subject: File Backup Options
569 A few days ago, a Bacula user who is backing up to file volumes and
570 using compression asked if it was possible to suppress compressing
571 all .gz files since it was a waste of CPU time. Although Bacula
572 currently permits using different options (compression, ...) on
573 a directory by directory basis, it cannot do it on a file by
574 file basis, which is clearly what was desired.
576 Proposed Implementation:
577 To solve this problem, I propose the following:
579 - Add a new Director resource type called FileOptions.
581 - The FileOptions resource will have records for all
582 options that can currently be specified on the Include record
583 (in a FileSet). Examples below.
585 - The FileOptions resource will permit an exclude option as well
586 as a number of additional options.
588 - The heart of the FileOptions resource is the ability to
589 supply any number of ApplyTo records which specify POSIX
590 regular expressions. These ApplyTo regular expressions are
591 applied to the fully qualified filename (path and all). If
592 one matches, then the FileOptions will be used.
594 - When an ApplyTo specification matches an included file, the
595 options specified in the FileOptions resource will override
596 the default options specified on the Include record.
598 - Include records will be modified to permit referencing one or
599 more FileOptions resources. The FileOptions will be used
600 in the order listed on the Include record and the first
601 one that matches will be applied.
603 - Options (or specifications) currently supplied on the Include
604 record will be deprecated (i.e. removed in a later version a
605 year or so from now).
607 - The Exclude record will be deprecated as the same functionality
608 can be obtained by using an Exclude = yes in the FileOptions.
611 The following records can appear in the FileOptions resource. An
612 asterisk preceding the name indicates a feature not currently
616 - Compression= (GZIP, ...)
617 - Signature= (MD5, SHA1, ...)
619 - OneFs= (yes/no) - remain on one filesystem
620 - Recurse= (yes/no) - recurse into subdirectories
621 - Sparse= (yes/no) - do sparse file backup
622 - *Exclude= (yes/no) - exclude file from being saved
623 - *Reader= (filename) - external read (backup) program
624 - *Plugin= (filename) - read/write plugin module
627 - verify= (ipnougsamc5) - verify options
630 - replace= (always/ifnewer/ifolder/never) - replace options currently
632 - *Writer= (filename) - external write (restore) program
636 Currently options specifying compression, MD5 signatures, recursion,
637 ... of a FileSet are supplied on the Include record. These will now
638 all be collected into a FileOptions resource, which will be
639 specified on the Include in place of the options. Multiple FileOptions
640 may be specified. Since the FileOptions contain regular expressions
641 that are applied to the full filename, this will give the ability
642 to specify backup options on a file by file basis to whatever level
651 Include = compression=GZIP signature=MD5 {
660 Include = FileOptions=Opts {
671 That's a lot more to do the same thing, but it gives the ability to
672 apply options on a file by file basis. For example, suppose you
673 want to compress all files but not any file with extensions .gz or .Z.
674 You could do so as follows:
678 Include = FileOptions=NoCompress FileOptions=Opts {
686 ApplyTo = /*.?*/ # matches all files
691 # Note multiple ApplyTos are ORed
692 ApplyTo = /*.gz/ # matches .gz files */
693 ApplyTo = /*.Z/ # matches .Z files */
696 Now, since the NoCompress FileOptions is specified first on the
697 Include line, any *.gz or *.Z file will have an MD5 signature computed,
698 but will not be compressed. For all other files, the NoCompress will not
699 match, so the Opts options will be used which will include GZIP
703 - Is it necessary to provide some means of ANDing regular expressions
704 and negation? (not currently planned)
706 e.g. ApplyTo = /*.gz/ && !/big.gz/
708 - I see that Networker has a "null" module which, if specified, does not
709 backup the file, but does make an record of the file in the catalog
710 so that the catalog will reflect an exact picture of the filesystem.
711 The result is that the file can be "seen" when "browsing" the save
712 sets, but it cannot be restored.
714 Is this really useful? Should it be implemented in Bacula?
717 After implementing the above, the user will be able to specify
718 on a file by file basis (using regular expressions) what options are
719 applied for the backup.

726 For each Incremental job that is run, there may be files that
727 were found but not saved because they were locked (this applies
728 only to Windows). Such a system could send back to the Director
729 a list of Unsaved files.
731 - New UnSavedFiles table that contains:
735 - Then in the next Incremental job, the list of Unsaved Files will be
736 feed to the FD, who will ensure that they are explicitly chosen even
737 if standard date/time check would not have selected them.
738 =============================================================
741 Done: (see kernsdone for more)
742 - Heartbeat between daemons.
743 - Fix Dir heartbeat in restore and verify vol. Be sure to make
744 bnet_recv() ignore BNET_HEARTBEAT.
745 - Implement HEART_BEAT while SD waiting for tapes.
746 - Include RunBeforeJob and RunAfterJob output in the message
748 - Change M_INFO to M_RESTORED for all restored files.
749 - Fix command prompt in gnome-console by checking on Ready.
