46 Testing to do: (painful)
47 - that ALL console command line options work and are always implemented
48 - blocksize recognition code.
49 - Test if rewind at end of tape waits for tape to rewind.
51 - Test not zeroing Autochanger slot when it is wrong.
52 - Test recycling and purging (code changed in db_find_next_volume and
54 - Figure out how to use ssh or stunnel to protect Bacula communications.
61 - Maybe remove multiple simultaneous devices code in SD.
62 - On Windows with very long path names, it may be impossible to create
63 a file (and thus restore it) because the total length is too long.
64 We must cd into the directory then create the file without the
66 - lstat() is not going to work on Win32 for testing date.
67 - Something is not right in last block of fill command.
68 - Implement a Recycle command
69 - Implement List Volume Job=xxx or List scheduled volumes or Status Director
70 - Add FileSet to command line arguments for restore.
71 - Do full check the command line args in update (e.g. VolStatus ...).
72 - Allow multiple Storage specifications (or multiple names on
73 a single Storage specification) in the Job record. Thus a job
74 can be backed up to a number of storage devices.
75 - Add client name to cram-md5 challenge so Director can immediately
76 verify if it is the correct client.
77 - Implement ClientRunBeforeJob and ClientRunAfterJob.
78 - Implement new alist in FileSet scanning.
79 - Add JobLevel in FD status (but make sure it is defined).
80 - Audit all UA commands to ensure that we always prompt where possible.
81 - Restrict characters permitted in a Resource name, and don't permit
83 - Prohibit backing up archive device (findlib/find_one.c:128)
84 - Make | and < work on FD side.
85 - Check Jmsg in bnet, may not work, must dup bsock.
86 - Suppress Job Name in Jmsg for console
87 - Create Pools that are referenced in a Run statement at startup if possible.
88 - Use runbeforejob to unload, then reload a volume previously used,
89 then the next job run gets an error reading the drive.
90 - Make bootstrap filename unique.
91 - Test a second language e.g. french.
92 - Start working on Base jobs.
93 - Make "make binary-release" work from any directory.
94 - Unsaved Flag in Job record (use JobMissingFiles).
95 - Base Flag in Job record.
96 - Implement UnsavedFiles DB record.
97 - Implement argc/argv for daemon command line scanning using table driven
99 - Implement table driven single argc/argv scanner to pickup all arguments.
100 Much like xxx_conf.c scan table.
101 keyword, handler(store_routine), store_address, code, flags, default.
102 - From Phil Stracchino:
103 It would probably be a per-client option, and would be called
104 something like, say, "Automatically purge obsoleted jobs". What it
105 would do is, when you successfully complete a Differential backup of a
106 client, it would automatically purge all Incremental backups for that
107 client that are rendered redundant by that Differential. Likewise,
108 when a Full backup on a client completed, it would automatically purge
109 all Differential and Incremental jobs obsoleted by that Full backup.
110 This would let people minimize the number of tapes they're keeping on
111 hand without having to master the art of retention times.
112 - Implement new serialize subroutines
113 send(socket, "string", &Vol, "uint32", &i, NULL)
114 - Scratch Pool where the volumes can be re-assigned to any Pool.
115 - Implement a M_SECURITY message class.
116 - Implement forward spacing block/file: position_device(bsr) --
117 just before read_block_from_device();
118 - When doing a Backup send all attributes back to the Director, who
119 would then figure out what files have been deleted.
120 - Currently in mount.c:236 the SD simply creates a Volume. It should have
121 explicit permission to do so. It should also mark the tape in error
122 if there is an error.
123 - Make sure all restore counters are working correctly in the FD.
124 - SD Bytes Read is wrong.
125 - Configure mtx-changer to have correct path to mtx.
126 - Look at ALL higher level routines that call block.c to be sure
127 they don't expect something in errmsg.
128 - Investigate doing RAW backup of Win32 partition.
129 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
130 - Add thread specific data to hold the jcr -- send error messages from
131 low level routines by accessing it and using Jmsg().
132 - Cancel waiting for Client connect in SD if FD goes away.
134 - Add Progress command that periodically reports the progress of
136 - One block was orphaned in the SD probably after cancel.
137 - Add all command line arguments to "update", e.g. slot=nn volStatus=append, ...
140 - Examine Bare Metal restore problem (a FD crash exists somewhere ...).
141 - Implement timeout in response() when it should come quickly.
142 - Implement console @echo command.
143 - Implement a Slot priority (loaded/not loaded).
144 - Implement "vacation" Incremental only saves.
145 - Implement single pane restore (much like the Gftp panes).
146 - Implement Automatic Mount even in operator wait.
147 - Implement create "FileSet"?
148 - Implement Release Device in the Job resource to unmount a drive.
149 - Implement Acquire Device in the Job resource to mount a drive,
150 be sure this works with admin jobs so that the user can get
151 prompted to insert the correct tape. Possibly some way to say to
152 run the job but don't save the files.
153 - Implement all command line args on run.
154 - Implement command line "restore" args.
155 - Implement "restore current select=no"
156 - Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
157 - Implement "scratch pool" where tapes are defined and can be
158 taken by any pool that needs them.
159 - Implement restore "current system", but take all files without
160 doing selection tree -- so that jobs without File records can
162 - Implement disk spooling. Two parts: 1. Spool to disk then
163 immediately to tape to speed up tape operations. 2. Spool to
164 disk only when the tape is full, then when a tape is hung move
166 - Implement a relocatable bacula.spec
167 - Implement dump/print label to UA
168 - Add prefixlinks to where or not where absolute links to FD.
169 - Issue message to mount a new tape before the rewind.
170 - Simplified client job initiation for portables.
171 - If SD cannot open a drive, make it periodically retry.
172 - Implement LabelTemplate (at least first cut).
173 - Add more of the config info to the tape label.
174 - Implement a Mount Command and an Unmount Command where
175 the users could specify a system command to be performed
176 to do the mount, after which Bacula could attempt to
177 read the device. This is for Removeable media such as a CDROM.
178 - Most likely, this mount command would be invoked explicitly
179 by the user using the current Console "mount" and "unmount"
180 commands -- the Storage Daemon would do the right thing
181 depending on the exact nature of the device.
182 - As with tape drives, when Bacula wanted a new removable
183 disk mounted, it would unmount the old one, and send a message
184 to the user, who would then use "mount" as described above
185 once he had actually inserted the disk.
187 - Make some way so that if a machine is skipped because it is not up
188 that Bacula will continue retrying for a specified period of time --
190 - If tape is marked read-only, then try opening it read-only rather than
191 failing, and remember that it cannot be written.
192 - Refine SD waiting output:
193 Device is being positioned
194 > Device is being positioned for append
195 > Device is being positioned to file x
197 - Figure out some way to estimate output size and to avoid splitting
198 a backup across two Volumes -- this could be useful for writing CDROMs
199 where you really prefer not to have it split -- not serious.
200 - Add RunBeforeJob and RunAfterJob to the Client program.
201 - Have SD compute MD5 or SHA1 and compare to what FD computes.
202 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
203 actual data on the Volume and compare it.
204 - Implement FileOptions (see end of this document)
205 - Implement Bacula plugins -- design API
206 - Make bcopy read through bad tape records.
207 - Fix read_record to handle multiple sessions.
208 - Program files (i.e. execute a program to read/write files).
209 Pass read date of last backup, size of file last time.
210 - Add Signature type to File DB record.
211 - CD into subdirectory when open()ing files for backup to
212 speed up things. Test with testfind().
213 - Priority job to go to top of list.
214 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
215 - Implement some way for the Console to dynamically create a job.
216 - Restore to a particular time -- e.g. before date, after date.
217 - Solaris -I on tar for include list
218 - Need a verbose mode in restore, perhaps to bsr.
219 - bscan without -v is too quiet -- perhaps show jobs.
220 - Add code to reject whole blocks if not wanted on restore.
221 - Check if we can increase Bacula FD priorty in Win2000
222 - Make sure the MaxVolFiles is fully implemented in SD
223 - Check if both CatalogFiles and UseCatalog are set to SD.
224 - Need return status on read_cb() from read_records(). Need multiple
225 records -- one per Job, maybe a JCR or some other structure with
226 a block and a record.
227 - Figure out how to do a bare metal Windows restore
228 - Possibly add email to Watchdog if drive is unmounted too
229 long and a job is waiting on the drive.
230 - Use read_record.c in SD code.
231 - Restore program that errors in SD due to no tape reports
232 OK incorrectly in output.
233 - After unmount, if restore job started, ask to mount.
234 - Convert all %x substitution variables, which are hard to remember
235 and read to %(variable-name). Idea from TMDA.
236 - Remove NextId for SQLite. Optimize.
237 - Move all SQL statements into a single location.
238 - Add UA rc and history files.
239 - put termcap (used by console) in ./configure and
240 allow -with-termcap-dir.
241 - Enhance time and size scanning routines.
242 - Fix Autoprune for Volumes to respect need for full save.
243 - Fix Win32 config file definition name on /install
244 - Compare tape to Client files (attributes, or attributes and data)
245 - Make all database Ids 64 bit.
246 - Write an applet for Linux.
247 - Add estimate to Console commands
248 - Implement new daemon communications protocol.
249 - Allow console commands to detach or run in background.
250 - Fix status delay on storage daemon during rewind.
251 - Add SD message variables to control operator wait time
252 - Maximum Operator Wait
253 - Minimum Message Interval
254 - Maximum Message Interval
255 - Send Operator message when cannot read tape label.
256 - Verify level=Volume (scan only), level=Data (compare of data to file).
257 Verify level=Catalog, level=InitCatalog
259 - Add keyword search to show command in Console.
260 - Events : tape has more than xxx bytes.
261 - Complete code in Bacula Resources -- this will permit
262 reading a new config file at any time.
263 - Handle ctl-c in Console
264 - Implement script driven addition of File daemon to config files.
265 - Think about how to make Bacula work better with File (non-tape) archives.
266 - Write Unix emulator for Windows.

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

631 Request For Comments For File Backup Options
634 Subject: File Backup Options
637 A few days ago, a Bacula user who is backing up to file volumes and
638 using compression asked if it was possible to suppress compressing
639 all .gz files since it was a waste of CPU time. Although Bacula
640 currently permits using different options (compression, ...) on
641 a directory by directory basis, it cannot do it on a file by
642 file basis, which is clearly what was desired.
644 Proposed Implementation:
645 To solve this problem, I propose the following:
647 - Add a new Director resource type called FileOptions.
649 - The FileOptions resource will have records for all
650 options that can currently be specified on the Include record
651 (in a FileSet). Examples below.
653 - The FileOptions resource will permit an exclude option as well
654 as a number of additional options.
656 - The heart of the FileOptions resource is the ability to
657 supply any number of ApplyTo records which specify POSIX
658 regular expressions. These ApplyTo regular expressions are
659 applied to the fully qualified filename (path and all). If
660 one matches, then the FileOptions will be used.
662 - When an ApplyTo specification matches an included file, the
663 options specified in the FileOptions resource will override
664 the default options specified on the Include record.
666 - Include records will be modified to permit referencing one or
667 more FileOptions resources. The FileOptions will be used
668 in the order listed on the Include record and the first
669 one that matches will be applied.
671 - Options (or specifications) currently supplied on the Include
672 record will be deprecated (i.e. removed in a later version a
673 year or so from now).
675 - The Exclude record will be deprecated as the same functionality
676 can be obtained by using an Exclude = yes in the FileOptions.
679 The following records can appear in the FileOptions resource. An
680 asterisk preceding the name indicates a feature not currently
684 - Compression= (GZIP, ...)
685 - Signature= (MD5, SHA1, ...)
687 - OneFs= (yes/no) - remain on one filesystem
688 - Recurse= (yes/no) - recurse into subdirectories
689 - Sparse= (yes/no) - do sparse file backup
690 - *Exclude= (yes/no) - exclude file from being saved
691 - *Reader= (filename) - external read (backup) program
692 - *Plugin= (filename) - read/write plugin module
695 - verify= (ipnougsamc5) - verify options
698 - replace= (always/ifnewer/ifolder/never) - replace options currently
700 - *Writer= (filename) - external write (restore) program
704 Currently options specifying compression, MD5 signatures, recursion,
705 ... of a FileSet are supplied on the Include record. These will now
706 all be collected into a FileOptions resource, which will be
707 specified on the Include in place of the options. Multiple FileOptions
708 may be specified. Since the FileOptions contain regular expressions
709 that are applied to the full filename, this will give the ability
710 to specify backup options on a file by file basis to whatever level
719 Include = compression=GZIP signature=MD5 {
728 Include = FileOptions=Opts {
739 That's a lot more to do the same thing, but it gives the ability to
740 apply options on a file by file basis. For example, suppose you
741 want to compress all files but not any file with extensions .gz or .Z.
742 You could do so as follows:
746 Include = FileOptions=NoCompress FileOptions=Opts {
754 ApplyTo = /*.?*/ # matches all files
759 # Note multiple ApplyTos are ORed
760 ApplyTo = /*.gz/ # matches .gz files */
761 ApplyTo = /*.Z/ # matches .Z files */
764 Now, since the NoCompress FileOptions is specified first on the
765 Include line, any *.gz or *.Z file will have an MD5 signature computed,
766 but will not be compressed. For all other files, the NoCompress will not
767 match, so the Opts options will be used which will include GZIP
771 - Is it necessary to provide some means of ANDing regular expressions
772 and negation? (not currently planned)
774 e.g. ApplyTo = /*.gz/ && !/big.gz/
776 - I see that Networker has a "null" module which, if specified, does not
777 backup the file, but does make an record of the file in the catalog
778 so that the catalog will reflect an exact picture of the filesystem.
779 The result is that the file can be "seen" when "browsing" the save
780 sets, but it cannot be restored.
782 Is this really useful? Should it be implemented in Bacula?
785 After implementing the above, the user will be able to specify
786 on a file by file basis (using regular expressions) what options are
787 applied for the backup.
790 =============================================
792 ==========================================================
794 For each Incremental job that is run, there may be files that
795 were found but not saved because they were locked (this applies
796 only to Windows). Such a system could send back to the Director
797 a list of Unsaved files.
799 - New UnSavedFiles table that contains:
803 - Then in the next Incremental job, the list of Unsaved Files will be
804 feed to the FD, who will ensure that they are explicitly chosen even
805 if standard date/time check would not have selected them.
806 =============================================================

935 - Don't zero the Slot when the wrong volume is found -- simply ask
937 - Implement MTIOCERRSTAT on FreeBSD to clear tape error conditions.
938 - Shell expansion fails for working_directory in SD from time to time.
939 - File the Automatically selected: xxx
940 to say Automatically selected Pool: xxx
941 - Default duration with no qualifier is sec should be 1 day
942 - zap sd_auth_key in SD after FD connection.
943 - Find a solution for the multiple FileSet problem (when it is changed). Add date?
944 - Look at Python for a Bacula scripting language -- www.python.org
945 - When Marking a file in Restore that is a hard link, also
946 mark the link so that the data will be reloaded.
947 - Emergency restore info:
949 - Backup working directory
951 - Why don't we get an error message from Win32 FD when bootstrap
952 file cannot be created for restore command?
953 - Fix Win2000 error with no messages during startup.
954 - Make restore more robust in counting error and not immediately bailing
955 out. Also print error message once, but try to continue.
956 - Add code to check that blocks are sequential on restore.
957 - Remove "rufus" and such references from regress.
958 - No READLINE_SRC if found in alternate directory.

960 - Find general solution for sscanf size problems (as well as sprintf. Do at run time?
961 - Bytes restored is wrong.
962 - The "List last 20 Jobs run" doesnt work correctly in restore.
963 It doesnt show the last 20 jobs , but some older ones.
964 - Fix Verify VolumeToCatalog to use BSRs -- it is broken.
965 - Implement Release Storage=xxx
966 - Fix restore on Win95/98
967 - Remove the Jmsg() in sql_find.c:102 or only print on hard error.
968 - Implement FileSet VolIndex -- done, but must update old records.
969 - Check this below from Phil.
970 This was SD reported data rather than FD data!
971 > When the job was done, Bacula reported 11084 files restored:

987 - Should Bacula make an Append tape as Purged when purging?
988 - Use switch() in backup.c and restore.c in FD instead of giant if statement.
989 - If during a restore, a hard linked file already exists (on option), delete
990 the file and re-link it. This is to avoid the possibility that the
991 user had re-linked the file between the backup and the restore.
992 Do lstat() to see if it is already properly linked.
993 Same for symlinked file.
994 Make sure ifnewer, ifolder, never, ... apply correctly.
995 - Flag so that no connect does not error, and Reschedule a job.

1004 thread, or set it in status.c cancel (used pthread_kill() instead of
1006 - Add restore to specific date.
1007 - Instrument use_count on DEVICE packets and ensure that the device is
1008 being close()ed at the appropriate time.
1009 - Test long path names (>64 chars) in Windows -- crashes FD?
1010 - Implement fast block rejection: match_bsr_block().
1011 - Complain if record dropped in bnet_recv because too long.
1012 - Test multiple simultaneous Volumes
1013 - Document recycling algorithm.
1014 - Make Restore report an error if FD or SD term codes are not OK.
1015 - To link with mysqlclient_r may require -lssl -lcrypto
1016 - Document Heart beat code
1017 - Non-fatal errors are not correct counting attribs.c:277
1018 - Check that Block number in JobMedia are correct.

1022 - Pass prefix_links to FD.
1023 - Fix restore list of volumes if Volume not selected.
1024 - Complete (or turn off) the command line code in update.
1025 - Testing Tibs job erred and hung director on Storage resource. This was
1026 because there were a whole pile of jobs hanging around in the SD
1027 waiting for a connection from the FD that was never coming.
1028 - Possibly update all client records at startup.
1029 - Listing of Win32 restored files has ??????? for user.
1030 - In Win portable restore the directory is not create

1035 - Finish Windows implementation (add setting of correct type on restore,
1036 add Portable Data Format flag).
1037 - Document portable=yes
1038 - Document c:/working directory better than /working directory.
1039 - Document run "yes".
1040 - Document update volume: jobid, current, before, all
1041 - Document that bscan does not work with multiple simultaneous jobs.
1042 - Update Automatic Volume Labeling in disk.wml
