39 - On Windows with very long path names, it may be impossible to create
40 a file (and thus restore it) because the total length is too long.
41 We must cd into the directory then create the file without the
43 - Move JobFiles and JobBytes to SD rather than FD -- more correct.
44 - Add client name to cram-md5 challenge so Director can immediately
45 verify if it is the correct client.
46 - Use runbeforejob to unload, then reload a volume previously used,

72 - Make | and < work on FD side.
73 - Pass prefix_links to FD.
74 - Implement a M_SECURITY message class.
75 - From Phil Stracchino:
76 It would probably be a per-client option, and would be called
77 something like, say, "Automatically purge obsoleted jobs". What it
78 would do is, when you successfully complete a Differential backup of a
79 client, it would automatically purge all Incremental backups for that
80 client that are rendered redundant by that Differential. Likewise,
81 when a Full backup on a client completed, it would automatically purge
82 all Differential and Incremental jobs obsoleted by that Full backup.
83 This would let people minimize the number of tapes they're keeping on
84 hand without having to master the art of retention times.
85 - Prohibit backing up archive device (findlib/find_one.c:128)
86 - Make Restore report an error if FD or SD term codes are not OK.
87 - Add JobLevel in FD status (but make sure it is defined).
88 - Restrict characters permitted in a Resource name, and don't permit
90 - Implement new serialize subroutines
91 send(socket, "string", &Vol, "uint32", &i, NULL)
92 - Audit all UA commands to ensure that we always prompt where possible.
93 - Scratch Pool where the volumes can be re-assigned to any Pool.
97 - When doing a Backup send all attributes back to the Director, who
98 would then figure out what files have been deleted.
99 - Currently in mount.c:236 the SD simply creates a Volume. It should have
100 explicit permission to do so. It should also mark the tape in error
101 if there is an error.
102 - Make sure all restore counters are working correctly in the FD.
103 - SD Bytes Read is wrong.
104 - Configure mtx-changer to have correct path to mtx.
105 - Look at ALL higher level routines that call block.c to be sure
106 they don't expect something in errmsg.
107 - Investigate doing RAW backup of Win32 partition.
108 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
109 - Add thread specific data to hold the jcr -- send error messages from
110 low level routines by accessing it and using Jmsg().
111 - Cancel waiting for Client connect in SD if FD goes away.
112 - Testing Tibs job erred and hung director on Storage resource. This was
113 because there were a whole pile of jobs hanging around in the SD
114 waiting for a connection from the FD that was never coming.
115 - Possibly update all client records at startup.
117 - Add Progress command that periodically reports the progress of
119 - One block was orphaned in the SD probably after cancel.
120 - Add all command line arguments to "update", e.g. slot=nn volStatus=append, ...
123 - Examine Bare Metal restore problem (a FD crash exists somewhere ...).
124 - Implement timeout in response() when it should come quickly.
125 - Implement console @echo command.
126 - Implement a Slot priority (loaded/not loaded).
127 - Implement "vacation" Incremental only saves.
128 - Implement single pane restore (much like the Gftp panes).
129 - Implement Automatic Mount even in operator wait.
130 - Implement create "FileSet"?
131 - Implement Release Device in the Job resource to unmount a drive.
132 - Implement Acquire Device in the Job resource to mount a drive,
133 be sure this works with admin jobs so that the user can get
134 prompted to insert the correct tape. Possibly some way to say to
135 run the job but don't save the files.
136 - Implement all command line args on run.
137 - Implement command line "restore" args.
138 - Implement "restore current select=no"
139 - Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
140 - Implement "scratch pool" where tapes are defined and can be
141 taken by any pool that needs them.
142 - Implement restore "current system", but take all files without
143 doing selection tree -- so that jobs without File records can
145 - Implement disk spooling. Two parts: 1. Spool to disk then
146 immediately to tape to speed up tape operations. 2. Spool to
147 disk only when the tape is full, then when a tape is hung move
149 - Implement a relocatable bacula.spec
150 - Allow multiple Storage specifications (or multiple names on
151 a single Storage specification) in the Job record. Thus a job
152 can be backed up to a number of storage devices.
153 - Implement dump/print label to UA
154 - Add prefixlinks to where or not where absolute links to FD.
155 - Issue message to mount a new tape before the rewind.
156 - Simplified client job initiation for portables.
157 - If SD cannot open a drive, make it periodically retry.
158 - Implement LabelTemplate (at least first cut).
159 - Add more of the config info to the tape label.
160 - Implement a Mount Command and an Unmount Command where
161 the users could specify a system command to be performed
162 to do the mount, after which Bacula could attempt to
163 read the device. This is for Removeable media such as a CDROM.
164 - Most likely, this mount command would be invoked explicitly
165 by the user using the current Console "mount" and "unmount"
166 commands -- the Storage Daemon would do the right thing
167 depending on the exact nature of the device.
168 - As with tape drives, when Bacula wanted a new removable
169 disk mounted, it would unmount the old one, and send a message
170 to the user, who would then use "mount" as described above
171 once he had actually inserted the disk.
173 - Make some way so that if a machine is skipped because it is not up
174 that Bacula will continue retrying for a specified period of time --
176 - If tape is marked read-only, then try opening it read-only rather than
177 failing, and remember that it cannot be written.
178 - Refine SD waiting output:
179 Device is being positioned
180 > Device is being positioned for append
181 > Device is being positioned to file x
183 - Figure out some way to estimate output size and to avoid splitting
184 a backup across two Volumes -- this could be useful for writing CDROMs
185 where you really prefer not to have it split -- not serious.
186 - Add RunBeforeJob and RunAfterJob to the Client program.
187 - Have SD compute MD5 or SHA1 and compare to what FD computes.
188 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
189 actual data on the Volume and compare it.
190 - Implement FileOptions (see end of this document)
191 - Implement Bacula plugins -- design API
192 - Make bcopy read through bad tape records.
193 - Fix read_record to handle multiple sessions.
194 - Program files (i.e. execute a program to read/write files).
195 Pass read date of last backup, size of file last time.
196 - Add Signature type to File DB record.
197 - CD into subdirectory when open()ing files for backup to
198 speed up things. Test with testfind().
199 - Priority job to go to top of list.
200 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
201 - Implement some way for the Console to dynamically create a job.
202 - Restore to a particular time -- e.g. before date, after date.
203 - Solaris -I on tar for include list
204 - Need a verbose mode in restore, perhaps to bsr.
205 - bscan without -v is too quiet -- perhaps show jobs.
206 - Add code to reject whole blocks if not wanted on restore.
207 - Check if we can increase Bacula FD priorty in Win2000
208 - Make sure the MaxVolFiles is fully implemented in SD
209 - Check if both CatalogFiles and UseCatalog are set to SD.
210 - Need return status on read_cb() from read_records(). Need multiple
211 records -- one per Job, maybe a JCR or some other structure with
212 a block and a record.
213 - Figure out how to do a bare metal Windows restore
214 - Possibly add email to Watchdog if drive is unmounted too
215 long and a job is waiting on the drive.
216 - Use read_record.c in SD code.
217 - Restore program that errors in SD due to no tape reports
218 OK incorrectly in output.
219 - After unmount, if restore job started, ask to mount.
220 - Convert all %x substitution variables, which are hard to remember
221 and read to %(variable-name). Idea from TMDA.
222 - Remove NextId for SQLite. Optimize.
223 - Move all SQL statements into a single location.
224 - Add UA rc and history files.
225 - put termcap (used by console) in ./configure and
226 allow -with-termcap-dir.
227 - Enhance time and size scanning routines.
228 - Fix Autoprune for Volumes to respect need for full save.
229 - Fix Win32 config file definition name on /install
230 - Compare tape to Client files (attributes, or attributes and data)

232 - Write an applet for Linux.
233 - Add estimate to Console commands
234 - Implement new daemon communications protocol.
235 - Allow console commands to detach or run in background.
236 - Fix status delay on storage daemon during rewind.
237 - Add SD message variables to control operator wait time
238 - Maximum Operator Wait
239 - Minimum Message Interval
240 - Maximum Message Interval

242 - Verify level=Volume (scan only), level=Data (compare of data to file).
243 Verify level=Catalog, level=InitCatalog
245 - Add keyword search to show command in Console.
246 - Events : tape has more than xxx bytes.
247 - Complete code in Bacula Resources -- this will permit
248 reading a new config file at any time.
249 - Handle ctl-c in Console
250 - Implement script driven addition of File daemon to config files.
251 - Think about how to make Bacula work better with File (non-tape) archives.
252 - Write Unix emulator for Windows.
253 - Put memory utilization in Status output of each daemon
254 if full status requested or if some level of debug on.
255 - Make database type selectable by .conf files i.e. at runtime
256 - Set flag for uname -a. Add to Volume label.
257 - Implement throttled work queue.

259 - Restore file modified before date
260 - Restore -- do nothing but show what would happen
261 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
262 - Implement Restore FileSet=
263 - Create a protocol.h and protocol.c where all protocol messages
265 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).

267 - Concept of precious tapes (cannot be reused).
268 - Make bcopy copy with a single tape drive.
269 - Permit changing ownership during restore.
272 > My suggestion: Add a feature on the systray menu-icon menu to request
273 > an immediate backup now. This would be useful for laptop users who may

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

617 Request For Comments For File Backup Options
620 Subject: File Backup Options
623 A few days ago, a Bacula user who is backing up to file volumes and
624 using compression asked if it was possible to suppress compressing
625 all .gz files since it was a waste of CPU time. Although Bacula
626 currently permits using different options (compression, ...) on
627 a directory by directory basis, it cannot do it on a file by
628 file basis, which is clearly what was desired.
630 Proposed Implementation:
631 To solve this problem, I propose the following:
633 - Add a new Director resource type called FileOptions.
635 - The FileOptions resource will have records for all
636 options that can currently be specified on the Include record
637 (in a FileSet). Examples below.
639 - The FileOptions resource will permit an exclude option as well
640 as a number of additional options.
642 - The heart of the FileOptions resource is the ability to
643 supply any number of ApplyTo records which specify POSIX
644 regular expressions. These ApplyTo regular expressions are
645 applied to the fully qualified filename (path and all). If
646 one matches, then the FileOptions will be used.
648 - When an ApplyTo specification matches an included file, the
649 options specified in the FileOptions resource will override
650 the default options specified on the Include record.
652 - Include records will be modified to permit referencing one or
653 more FileOptions resources. The FileOptions will be used
654 in the order listed on the Include record and the first
655 one that matches will be applied.
657 - Options (or specifications) currently supplied on the Include
658 record will be deprecated (i.e. removed in a later version a
659 year or so from now).
661 - The Exclude record will be deprecated as the same functionality
662 can be obtained by using an Exclude = yes in the FileOptions.
665 The following records can appear in the FileOptions resource. An
666 asterisk preceding the name indicates a feature not currently
670 - Compression= (GZIP, ...)
671 - Signature= (MD5, SHA1, ...)
673 - OneFs= (yes/no) - remain on one filesystem
674 - Recurse= (yes/no) - recurse into subdirectories
675 - Sparse= (yes/no) - do sparse file backup
676 - *Exclude= (yes/no) - exclude file from being saved
677 - *Reader= (filename) - external read (backup) program
678 - *Plugin= (filename) - read/write plugin module
681 - verify= (ipnougsamc5) - verify options
684 - replace= (always/ifnewer/ifolder/never) - replace options currently
686 - *Writer= (filename) - external write (restore) program
690 Currently options specifying compression, MD5 signatures, recursion,
691 ... of a FileSet are supplied on the Include record. These will now
692 all be collected into a FileOptions resource, which will be
693 specified on the Include in place of the options. Multiple FileOptions
694 may be specified. Since the FileOptions contain regular expressions
695 that are applied to the full filename, this will give the ability
696 to specify backup options on a file by file basis to whatever level
705 Include = compression=GZIP signature=MD5 {
714 Include = FileOptions=Opts {
725 That's a lot more to do the same thing, but it gives the ability to
726 apply options on a file by file basis. For example, suppose you
727 want to compress all files but not any file with extensions .gz or .Z.
728 You could do so as follows:
732 Include = FileOptions=NoCompress FileOptions=Opts {
740 ApplyTo = /*.?*/ # matches all files
745 # Note multiple ApplyTos are ORed
746 ApplyTo = /*.gz/ # matches .gz files */
747 ApplyTo = /*.Z/ # matches .Z files */
750 Now, since the NoCompress FileOptions is specified first on the
751 Include line, any *.gz or *.Z file will have an MD5 signature computed,
752 but will not be compressed. For all other files, the NoCompress will not
753 match, so the Opts options will be used which will include GZIP
757 - Is it necessary to provide some means of ANDing regular expressions
758 and negation? (not currently planned)
760 e.g. ApplyTo = /*.gz/ && !/big.gz/
762 - I see that Networker has a "null" module which, if specified, does not
763 backup the file, but does make an record of the file in the catalog
764 so that the catalog will reflect an exact picture of the filesystem.
765 The result is that the file can be "seen" when "browsing" the save
766 sets, but it cannot be restored.
768 Is this really useful? Should it be implemented in Bacula?
771 After implementing the above, the user will be able to specify
772 on a file by file basis (using regular expressions) what options are
773 applied for the backup.
776 =============================================
778 ==========================================================
780 For each Incremental job that is run, there may be files that
781 were found but not saved because they were locked (this applies
782 only to Windows). Such a system could send back to the Director
783 a list of Unsaved files.
785 - New UnSavedFiles table that contains:
789 - Then in the next Incremental job, the list of Unsaved Files will be
790 feed to the FD, who will ensure that they are explicitly chosen even
791 if standard date/time check would not have selected them.
792 =============================================================

921 - Don't zero the Slot when the wrong volume is found -- simply ask
923 - Implement MTIOCERRSTAT on FreeBSD to clear tape error conditions.
924 - Shell expansion fails for working_directory in SD from time to time.
925 - File the Automatically selected: xxx
926 to say Automatically selected Pool: xxx
927 - Default duration with no qualifier is sec should be 1 day
928 - zap sd_auth_key in SD after FD connection.
929 - Find a solution for the multiple FileSet problem (when it is changed). Add date?
930 - Look at Python for a Bacula scripting language -- www.python.org
931 - When Marking a file in Restore that is a hard link, also
932 mark the link so that the data will be reloaded.
933 - Emergency restore info:
935 - Backup working directory
937 - Why don't we get an error message from Win32 FD when bootstrap
938 file cannot be created for restore command?
939 - Fix Win2000 error with no messages during startup.
940 - Make restore more robust in counting error and not immediately bailing
941 out. Also print error message once, but try to continue.
942 - Add code to check that blocks are sequential on restore.
943 - Remove "rufus" and such references from regress.
944 - No READLINE_SRC if found in alternate directory.
945 - If ./btape is called without /dev, assume argument is a Storage resource name.
946 - Find general solution for sscanf size problems (as well as sprintf. Do at run time?
947 - Bytes restored is wrong.
948 - The "List last 20 Jobs run" doesnt work correctly in restore.
949 It doesnt show the last 20 jobs , but some older ones.
950 - Fix Verify VolumeToCatalog to use BSRs -- it is broken.
951 - Implement Release Storage=xxx
952 - Fix restore on Win95/98
953 - Remove the Jmsg() in sql_find.c:102 or only print on hard error.
954 - Implement FileSet VolIndex -- done, but must update old records.
955 - Check this below from Phil.
956 This was SD reported data rather than FD data!

973 - Should Bacula make an Append tape as Purged when purging?
974 - Use switch() in backup.c and restore.c in FD instead of giant if statement.
975 - If during a restore, a hard linked file already exists (on option), delete
976 the file and re-link it. This is to avoid the possibility that the
977 user had re-linked the file between the backup and the restore.
978 Do lstat() to see if it is already properly linked.
979 Same for symlinked file.
980 Make sure ifnewer, ifolder, never, ... apply correctly.
981 - Flag so that no connect does not error, and Reschedule a job.
982 - Implement "Reschedule OnError=yes interval=nnn times=xxx"
983 - That restoring a hard link that already exists works correctly.
985 - Make Pool resource handle Counter resources.
986 - Fix first block number after label to be zero instead of 1 (reset after label).
987 - Grep for Backup OK in regression script.
988 - Do NOT reuse same JobId if tape written.
989 - Implement non-blocking writes and bsock->terminate in heartbeat
990 thread, or set it in status.c cancel (used pthread_kill() instead of
992 - Add restore to specific date.
993 - Instrument use_count on DEVICE packets and ensure that the device is
994 being close()ed at the appropriate time.
995 - Test long path names (>64 chars) in Windows -- crashes FD?
996 - Implement fast block rejection: match_bsr_block().
