58 restored does not match # expected.
59 - User wants to NOT backup up certain big files (email files).
60 - Maybe remove multiple simultaneous devices code in SD.
61 - On Windows with very long path names, it may be impossible to create
62 a file (and thus restore it) because the total length is too long.
63 We must cd into the directory then create the file without the

94 - Implement table driven single argc/argv scanner to pickup all arguments.
95 Much like xxx_conf.c scan table.
96 keyword, handler(store_routine), store_address, code, flags, default.
97 - From Phil Stracchino:
98 It would probably be a per-client option, and would be called
99 something like, say, "Automatically purge obsoleted jobs". What it
100 would do is, when you successfully complete a Differential backup of a
101 client, it would automatically purge all Incremental backups for that
102 client that are rendered redundant by that Differential. Likewise,
103 when a Full backup on a client completed, it would automatically purge
104 all Differential and Incremental jobs obsoleted by that Full backup.
105 This would let people minimize the number of tapes they're keeping on
106 hand without having to master the art of retention times.
107 - Implement new serialize subroutines
108 send(socket, "string", &Vol, "uint32", &i, NULL)
109 - Scratch Pool where the volumes can be re-assigned to any Pool.
110 - Implement a M_SECURITY message class.
111 - Implement forward spacing block/file: position_device(bsr) --
112 just before read_block_from_device();
113 - When doing a Backup send all attributes back to the Director, who
114 would then figure out what files have been deleted.
115 - Currently in mount.c:236 the SD simply creates a Volume. It should have
116 explicit permission to do so. It should also mark the tape in error
117 if there is an error.
118 - Make sure all restore counters are working correctly in the FD.
119 - SD Bytes Read is wrong.
120 - Configure mtx-changer to have correct path to mtx.
121 - Look at ALL higher level routines that call block.c to be sure
122 they don't expect something in errmsg.
123 - Investigate doing RAW backup of Win32 partition.
124 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
125 - Add thread specific data to hold the jcr -- send error messages from
126 low level routines by accessing it and using Jmsg().
127 - Cancel waiting for Client connect in SD if FD goes away.
129 - Add Progress command that periodically reports the progress of
131 - One block was orphaned in the SD probably after cancel.
132 - Add all command line arguments to "update", e.g. slot=nn volStatus=append, ...
135 - Examine Bare Metal restore problem (a FD crash exists somewhere ...).
136 - Implement timeout in response() when it should come quickly.
137 - Implement console @echo command.
138 - Implement a Slot priority (loaded/not loaded).
139 - Implement "vacation" Incremental only saves.
140 - Implement single pane restore (much like the Gftp panes).
141 - Implement Automatic Mount even in operator wait.
142 - Implement create "FileSet"?
143 - Implement Release Device in the Job resource to unmount a drive.
144 - Implement Acquire Device in the Job resource to mount a drive,
145 be sure this works with admin jobs so that the user can get
146 prompted to insert the correct tape. Possibly some way to say to
147 run the job but don't save the files.
148 - Implement all command line args on run.
149 - Implement command line "restore" args.
150 - Implement "restore current select=no"
151 - Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
152 - Implement "scratch pool" where tapes are defined and can be
153 taken by any pool that needs them.
154 - Implement restore "current system", but take all files without
155 doing selection tree -- so that jobs without File records can
157 - Implement disk spooling. Two parts: 1. Spool to disk then
158 immediately to tape to speed up tape operations. 2. Spool to
159 disk only when the tape is full, then when a tape is hung move
161 - Implement a relocatable bacula.spec
162 - Implement dump/print label to UA
163 - Add prefixlinks to where or not where absolute links to FD.
164 - Issue message to mount a new tape before the rewind.
165 - Simplified client job initiation for portables.
166 - If SD cannot open a drive, make it periodically retry.
167 - Implement LabelTemplate (at least first cut).
168 - Add more of the config info to the tape label.
169 - Implement a Mount Command and an Unmount Command where
170 the users could specify a system command to be performed
171 to do the mount, after which Bacula could attempt to
172 read the device. This is for Removeable media such as a CDROM.
173 - Most likely, this mount command would be invoked explicitly
174 by the user using the current Console "mount" and "unmount"
175 commands -- the Storage Daemon would do the right thing
176 depending on the exact nature of the device.
177 - As with tape drives, when Bacula wanted a new removable
178 disk mounted, it would unmount the old one, and send a message
179 to the user, who would then use "mount" as described above
180 once he had actually inserted the disk.
182 - Make some way so that if a machine is skipped because it is not up
183 that Bacula will continue retrying for a specified period of time --
185 - If tape is marked read-only, then try opening it read-only rather than
186 failing, and remember that it cannot be written.
187 - Refine SD waiting output:
188 Device is being positioned
189 > Device is being positioned for append
190 > Device is being positioned to file x
192 - Figure out some way to estimate output size and to avoid splitting
193 a backup across two Volumes -- this could be useful for writing CDROMs
194 where you really prefer not to have it split -- not serious.
195 - Add RunBeforeJob and RunAfterJob to the Client program.
196 - Have SD compute MD5 or SHA1 and compare to what FD computes.
197 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
198 actual data on the Volume and compare it.
199 - Implement FileOptions (see end of this document)
200 - Implement Bacula plugins -- design API
201 - Make bcopy read through bad tape records.

204 Pass read date of last backup, size of file last time.
205 - Add Signature type to File DB record.
206 - CD into subdirectory when open()ing files for backup to
207 speed up things. Test with testfind().
208 - Priority job to go to top of list.
209 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.

216 - Check if we can increase Bacula FD priorty in Win2000
217 - Make sure the MaxVolFiles is fully implemented in SD
218 - Check if both CatalogFiles and UseCatalog are set to SD.
219 - Need return status on read_cb() from read_records(). Need multiple
220 records -- one per Job, maybe a JCR or some other structure with
221 a block and a record.
222 - Figure out how to do a bare metal Windows restore
223 - Possibly add email to Watchdog if drive is unmounted too
224 long and a job is waiting on the drive.
225 - Use read_record.c in SD code.
226 - Restore program that errors in SD due to no tape reports
227 OK incorrectly in output.
228 - After unmount, if restore job started, ask to mount.
229 - Convert all %x substitution variables, which are hard to remember
230 and read to %(variable-name). Idea from TMDA.
231 - Remove NextId for SQLite. Optimize.
232 - Move all SQL statements into a single location.
233 - Add UA rc and history files.
234 - put termcap (used by console) in ./configure and
235 allow -with-termcap-dir.
236 - Enhance time and size scanning routines.
237 - Fix Autoprune for Volumes to respect need for full save.
238 - Fix Win32 config file definition name on /install

245 - Fix status delay on storage daemon during rewind.
246 - Add SD message variables to control operator wait time
247 - Maximum Operator Wait
248 - Minimum Message Interval

251 - Verify level=Volume (scan only), level=Data (compare of data to file).
252 Verify level=Catalog, level=InitCatalog
254 - Add keyword search to show command in Console.
255 - Events : tape has more than xxx bytes.
256 - Complete code in Bacula Resources -- this will permit
257 reading a new config file at any time.
258 - Handle ctl-c in Console
259 - Implement script driven addition of File daemon to config files.
260 - Think about how to make Bacula work better with File (non-tape) archives.

277 - Make bcopy copy with a single tape drive.
278 - Permit changing ownership during restore.

292 - Autolabel should be specified by DIR instead of SD.
295 - AutoScan (check checksum of tape)
296 - Format command = "format /dev/nst0"
300 - Seek resolution (usually corresponds to buffer size)
301 - EODErrorCode=ENOSPC or code
302 - Partial Read error code
303 - Partial write error code
304 - Nonformatted read error
305 - Nonformatted write error
306 - WriteProtected error
310 - IgnoreCloseErrors=yes
320 - FD sends unsaved file list to Director at end of job (see
322 - File daemon should build list of files skipped, and then
323 at end of save retry and report any errors.
324 - Write a Storage daemon that uses pipes and
325 standard Unix programs to write to the tape.
327 - Need something that monitors the JCR queue and
328 times out jobs by asking the deamons where they are.
329 - Enhance Jmsg code to permit buffering and saving to disk.
330 - device driver = "xxxx" for drives.
332 - Ensure that /dev/null works
333 - Need report class for messages. Perhaps
334 report resource where report=group of messages
335 - enhance scan_attrib and rename scan_jobtype, and
336 fill in code for "since" option
337 - Director needs a time after which the report status is sent
338 anyway -- or better yet, a retry time for the job.
339 - Don't reschedule a job if previous incarnation is still running.
340 - Some way to automatically backup everything is needed????
341 - Need a structure for pending actions:
343 - termination status (part of buffered msgs?)
345 Read, Write, Clean, Delete
346 - Login to Bacula; Bacula users with different permissions:
347 owner, group, user, quotas
348 - Store info on each file system type (probably in the job header on tape.
349 This could be the output of df; or perhaps some sort of /etc/mtab record.
352 - Design at hierarchial storage for Bacula. Migration and Clone.
353 - Implement FSM (File System Modules).
354 - Audit M_ error codes to ensure they are correct and consistent.
355 - Add variable break characters to lex analyzer.
356 Either a bit mask or a string of chars so that
357 the caller can change the break characters.
358 - Make a single T_BREAK to replace T_COMMA, etc.
359 - Ensure that File daemon and Storage daemon can
360 continue a save if the Director goes down (this
361 is NOT currently the case). Must detect socket error,
362 buffer messages for later.
363 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
364 - Add ability to backup to two Storage devices (two SD sessions) at
365 the same time -- e.g. onsite, offsite.
366 - Add the ability to consolidate old backup sets (basically do a restore
367 to tape and appropriately update the catalog). Compress Volume sets.
368 Might need to spool via file is only one drive is available.
369 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
370 someway to do so with every volume that has less than x% valid
374 Migration: Move a backup from one Volume to another
375 Clone: Copy a backup -- two Volumes
377 Bacula Migration is based on Jobs (apparently Networker is file by file).
379 Migration triggered by:
383 Highwater mark (keep total size)
387 Bacula Projects Roadmap
389 last update 8 May 2003
391 Item 1: Multiple simultaneous Jobs. (done)
392 Done -- Restore part needs better implementation to work correctly
393 Also, it needs considerable testing
395 What: Permit multiple simultaneous jobs in Bacula.
397 Why: An enterprise level solution needs to go fast without the
398 need for the system administrator to carefully tweak
399 timing. Based on the benchmarks, during a full
400 backup, NetWorker typically hit 10 times the bandwidth to
401 the tape compared to Bacula--largely. This is probably due to
402 running parallel jobs and multi-threaded filling of buffers
403 and writing them to tape. This should also make things work
404 better when you have a mix of fast and slow machines backing
407 Notes: Bacula was designed to run multiple simultaneous jobs. Thus
408 implementing this is a matter of some small cleanups and
412 Item 2: Make the Storage daemon use intermediate file storage to buffer data.
413 Deferred -- not necessary yet -- possibly implement with Migration.
415 What: If data is coming into the SD too fast, buffer it to
416 disk if the user has configured this option.
418 Why: This would be nice, especially if it more or less falls out
419 when implementing (1) above. If not, it probably should not
420 be given a high priority because fundamentally the backup time
421 is limited by the tape bandwidth. Even though you may finish a
422 client job quicker by spilling to disk, you still have to
423 eventually get it onto tape. If intermediate disk buffering
424 allows us to improve write bandwidth to tape, it may make
427 Notes: Whether or not this is implemented will depend upon performance
428 testing after item 1 is implemented.
431 Item 3: Write the bscan program -- also write a bcopy program.
434 What: Write a program that reads a Bacula tape and puts all the
435 appropriate data into the catalog. This allows recovery
436 from a tape that is no longer in the database, or it allows
437 re-creation of a database if lost.
439 Why: This is a fundamental robustness and disaster recovery tool
440 which will increase the comfort level of a sysadmin
441 considering adopting Bacula.
443 Notes: A skeleton of this program already exists, but much work
444 needs to be done. Implementing this will also make apparent
445 any deficiencies in the current Bacula tape format.
448 Item 4: Implement Base jobs.
450 What: A base job is sort of like a Full save except that you
451 will want the FileSet to contain only files that are unlikely
452 to change in the future (i.e. a snapshot of most of your
453 system after installing it). After the base job has been run,
454 when you are doing a Full save, you can specify to exclude
455 all files saved by the base job that have not been modified.
457 Why: This is something none of the competition does, as far as we know
458 (except BackupPC, which is a Perl program that saves to disk
459 only). It is big win for the user, it makes Bacula stand out
460 as offering a unique optimization that immediately saves time
463 Notes: Big savings in tape usage. Will require more resources because
464 the e. DIR must send FD a list of files/attribs, and the FD must
465 search the list and compare it for each file to be saved.
468 Item 5: Implement Label templates
471 What: This is a mechanism whereby Bacula can automatically create
472 a tape label for new tapes according to a detailed specification
473 provided by the user.
475 Why: It is a major convenience item for folks who use automated label
478 Notes: Bacula already has a working form of automatic tape label
479 creation, but it is very crude. The design for the complete
480 tape labeling project is already documented in the manual.
483 Item 6: Write a regression script.
484 Done -- Continue to expand its testing.
486 What: This is an automatic script that runs and tests as many features
487 of Bacula as possible. The output is compared to previous
488 versions of Bacula and any differences are reported.
490 Why: This is an enormous help in preventing introduction of new
491 errors in parts of the program that already work correctly.
493 Notes: This probably should be ranked higher, it's something the typical
494 user doesn't see. Depending on how it's implemented, it may
495 make sense to defer it until the archival tape format and
496 user interface mature.
499 Item 7: GUI for interactive restore
500 Item 8: GUI for interactive backup
502 What: The current interactive restore is implemented with a tty
503 interface. It would be much nicer to be able to "see" the
504 list of files backed up in typical GUI tree format.
505 The same mechanism could also be used for creating
506 ad-hoc backup FileSets (item 8).
508 Why: Ease of use -- especially for the end user.
510 Notes: Rather than implementing in Gtk, we probably should go directly
511 for a Browser implementation, even if doing so meant the
512 capability wouldn't be available until much later. Not only
513 is there the question of Windows sites, most
514 Solaris/HP/IRIX, etc, shops can't currently run Gtk programs
515 without installing lots of stuff admins are very wary about.
516 Real sysadmins will always use the command line anyway, and
517 the user who's doing an interactive restore or backup of his
518 own files will in most cases be on a Windows machine running
522 Item 9: Add SSL to daemon communications.
524 What: This provides for secure communications between the daemons.
526 Why: This would allow doing backup across the Internet without
527 privacy concerns (or with much less concern).
529 Notes: The vast majority of near term potential users will be backing up
530 a single site over a LAN and, correctly or not, they probably
531 won't be concerned with security, at least not enough to go to
532 the trouble to set up keys, etc. to screw things down. We suspect
533 that many users genuinely interested in multi-site backup
534 already run some form of VPN software in their internetwork
535 connections, and are willing to delegate security to that layer.
538 Item 10: Define definitive tape format.
541 What: Define that definitive tape format that will not change
542 for the next millennium.
544 Why: Stability, security.
546 Notes: See notes for item 11 below.
549 Item 11: New daemon communication protocol.
551 What: The current daemon to daemon protocol is basically an ASCII
552 printf() and sending the buffer. On the receiving end, the
553 buffer is sscanf()ed to unpack it. The new scheme would
554 be a binary format that allows quick packing and unpacking
555 of any data type with named fields.
557 Why: Using binary packing would be faster. Named fields will permit
558 error checking to ensure that what is sent is what the
559 receiver really wants.
561 Notes: These are internal improvements in the interest of the
562 long-term stability and evolution of the program. On the one
563 hand, the sooner they're done, the less code we have to rip
564 up when the time comes to install them. On the other hand, they
565 don't bring an immediately perceptible benefit to potential
566 users. Item 10 and possibly item 11 should be deferred until Bacula
567 is well established with a growing user community more or
568 less happy with the feature set. At that time, it will make a
569 good "next generation" upgrade in the interest of data
575 ======================================================
577 It is somewhat like a Full save becomes an incremental since
578 the Base job (or jobs) plus other non-base files.
580 - New BaseFile table that contains:
581 JobId, BaseJobId, FileId (from Base).
582 i.e. for each base file that exists but is not saved because
583 it has not changed, the File daemon sends the JobId, BaseId,
584 and FileId back to the Director who creates the DB entry.
585 - To initiate a Base save, the Director sends the FD
586 the FileId, and full filename for each file in the Base.
587 - When the FD finds a Base file, he requests the Director to
588 send him the full File entry (stat packet plus MD5), or
589 conversely, the FD sends it to the Director and the Director
590 says yes or no. This can be quite rapid if the FileId is kept
591 by the FD for each Base Filename.
592 - It is probably better to have the comparison done by the FD
593 despite the fact that the File entry must be sent across the
595 - An alternative would be to send the FD the whole File entry
596 from the start. The disadvantage is that it requires a lot of
597 space. The advantage is that it requires less communications
599 - The Job record must be updated to indicate that one or more
601 - At end of Job, FD returns:
602 1. Count of base files/bytes not written to tape (i.e. matches)
603 2. Count of base file that were saved i.e. had changed.
604 - No tape record would be written for a Base file that matches, in the
605 same way that no tape record is written for Incremental jobs where
606 the file is not saved because it is unchanged.
607 - On a restore, all the Base file records must explicitly be
608 found from the BaseFile tape. I.e. for each Full save that is marked
609 to have one or more Base Jobs, search the BaseFile for all occurrences
611 - An optimization might be to make the BaseFile have:
617 This would avoid the need to explicitly fetch each File record for
618 the Base job. The Base Job record will be fetched to get the
619 VolSessionId and VolSessionTime.

626 Request For Comments For File Backup Options
629 Subject: File Backup Options
632 A few days ago, a Bacula user who is backing up to file volumes and
633 using compression asked if it was possible to suppress compressing
634 all .gz files since it was a waste of CPU time. Although Bacula
635 currently permits using different options (compression, ...) on
636 a directory by directory basis, it cannot do it on a file by
637 file basis, which is clearly what was desired.
639 Proposed Implementation:
640 To solve this problem, I propose the following:
642 - Add a new Director resource type called FileOptions.
644 - The FileOptions resource will have records for all
645 options that can currently be specified on the Include record
646 (in a FileSet). Examples below.
648 - The FileOptions resource will permit an exclude option as well
649 as a number of additional options.
651 - The heart of the FileOptions resource is the ability to
652 supply any number of ApplyTo records which specify POSIX
653 regular expressions. These ApplyTo regular expressions are
654 applied to the fully qualified filename (path and all). If
655 one matches, then the FileOptions will be used.
657 - When an ApplyTo specification matches an included file, the
658 options specified in the FileOptions resource will override
659 the default options specified on the Include record.
661 - Include records will be modified to permit referencing one or
662 more FileOptions resources. The FileOptions will be used
663 in the order listed on the Include record and the first
664 one that matches will be applied.
666 - Options (or specifications) currently supplied on the Include
667 record will be deprecated (i.e. removed in a later version a
668 year or so from now).
670 - The Exclude record will be deprecated as the same functionality
671 can be obtained by using an Exclude = yes in the FileOptions.
674 The following records can appear in the FileOptions resource. An
675 asterisk preceding the name indicates a feature not currently
679 - Compression= (GZIP, ...)
680 - Signature= (MD5, SHA1, ...)
682 - OneFs= (yes/no) - remain on one filesystem
683 - Recurse= (yes/no) - recurse into subdirectories
684 - Sparse= (yes/no) - do sparse file backup
685 - *Exclude= (yes/no) - exclude file from being saved
686 - *Reader= (filename) - external read (backup) program
687 - *Plugin= (filename) - read/write plugin module
690 - verify= (ipnougsamc5) - verify options
693 - replace= (always/ifnewer/ifolder/never) - replace options currently
695 - *Writer= (filename) - external write (restore) program
699 Currently options specifying compression, MD5 signatures, recursion,
700 ... of a FileSet are supplied on the Include record. These will now
701 all be collected into a FileOptions resource, which will be
702 specified on the Include in place of the options. Multiple FileOptions
703 may be specified. Since the FileOptions contain regular expressions
704 that are applied to the full filename, this will give the ability
705 to specify backup options on a file by file basis to whatever level
714 Include = compression=GZIP signature=MD5 {
726 Match = /*.?*/ # matches all files.
731 That's a lot more to do the same thing, but it gives the ability to
732 apply options on a file by file basis. For example, suppose you
733 want to compress all files but not any file with extensions .gz or .Z.
734 You could do so as follows:
741 # Note multiple Matches are ORed
742 Match = /*.gz/ # matches .gz files */
743 Match = /*.Z/ # matches .Z files */
748 Match = /*.?*/ # matches all files
754 Now, since the NoCompress FileOptions is specified first on the
755 Include line, any *.gz or *.Z file will have an MD5 signature computed,
756 but will not be compressed. For all other files, the NoCompress will not
757 match, so the Opts options will be used which will include GZIP
761 - Is it necessary to provide some means of ANDing regular expressions
762 and negation? (not currently planned)
764 e.g. Match = /*.gz/ && !/big.gz/
766 - I see that Networker has a "null" module which, if specified, does not
767 backup the file, but does make an record of the file in the catalog
768 so that the catalog will reflect an exact picture of the filesystem.
769 The result is that the file can be "seen" when "browsing" the save
770 sets, but it cannot be restored.
772 Is this really useful? Should it be implemented in Bacula?
775 After implementing the above, the user will be able to specify
776 on a file by file basis (using regular expressions) what options are
777 applied for the backup.

782 ==========================================================
784 For each Incremental job that is run, there may be files that
785 were found but not saved because they were locked (this applies
786 only to Windows). Such a system could send back to the Director
787 a list of Unsaved files.
789 - New UnSavedFiles table that contains:
793 - Then in the next Incremental job, the list of Unsaved Files will be
794 feed to the FD, who will ensure that they are explicitly chosen even
795 if standard date/time check would not have selected them.
796 =============================================================
799 Done: (see kernsdone for more)
800 - Implement new alist in FileSet scanning.
801 - bls should continue reading even if it finds Win32 data on the tape.
802 The error should be Warning rather the Error.
803 - Add user configurable timeout for connecting to SD.
804 - Unsaved Flag in Job record (use JobMissingFiles).
805 - Base Flag in Job record.
