4 Documentation to do: (any release a little bit at a time)
5 - Document running a test version.
6 - Document query file format.
7 - Document static linking
8 - Document problems with Verify and pruning.
9 - Document how to use multiple databases.
10 - For FreeBSD typical /dev/nrsa0 and for mtx /dev/pass1
11 - VXA drives have a "cleaning required"
12 indicator, but Exabyte recommends preventive cleaning after every 75
14 - Lookup HP cleaning recommendations.
15 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
16 - Document FInclude ...
17 - Document all the status codes JobLevel, JobType, JobStatus.
19 Testing to do: (painful)
20 - that ALL console command line options work and are always implemented
21 - blocksize recognition code.
22 - Test if rewind at end of tape waits for tape to rewind.
24 - Test not zeroing Autochanger slot when it is wrong.
25 - Test recycling and purging (code changed in db_find_next_volume and
27 - Figure out how to use ssh or stunnel to protect Bacula communications.
34 - Maybe remove multiple simultaneous devices code in SD.
35 - On Windows with very long path names, it may be impossible to create
36 a file (and thus restore it) because the total length is too long.
37 We must cd into the directory then create the file without the
39 - lstat() is not going to work on Win32 for testing date.
40 - Something is not right in last block of fill command.
41 - Implement a Recycle command

44 - Do full check the command line args in update (e.g. VolStatus ...).
45 - Allow multiple Storage specifications (or multiple names on
46 a single Storage specification) in the Job record. Thus a job
47 can be backed up to a number of storage devices.

67 - Unsaved Flag in Job record (use JobMissingFiles).
68 - Base Flag in Job record.
69 - Implement UnsavedFiles DB record.
70 - Implement argc/argv for daemon command line scanning using table driven
72 - Implement table driven single argc/argv scanner to pickup all arguments.
73 Much like xxx_conf.c scan table.
74 keyword, handler(store_routine), store_address, code, flags, default.
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 - Implement new serialize subroutines
86 send(socket, "string", &Vol, "uint32", &i, NULL)
87 - Scratch Pool where the volumes can be re-assigned to any Pool.
88 - Implement a M_SECURITY message class.
89 - Implement forward spacing block/file: position_device(bsr) --
90 just before read_block_from_device();
91 - When doing a Backup send all attributes back to the Director, who
92 would then figure out what files have been deleted.
93 - Currently in mount.c:236 the SD simply creates a Volume. It should have
94 explicit permission to do so. It should also mark the tape in error
96 - Make sure all restore counters are working correctly in the FD.
97 - SD Bytes Read is wrong.
98 - Configure mtx-changer to have correct path to mtx.
99 - Look at ALL higher level routines that call block.c to be sure
100 they don't expect something in errmsg.
101 - Investigate doing RAW backup of Win32 partition.
102 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
103 - Add thread specific data to hold the jcr -- send error messages from
104 low level routines by accessing it and using Jmsg().
105 - Cancel waiting for Client connect in SD if FD goes away.
107 - Add Progress command that periodically reports the progress of
109 - One block was orphaned in the SD probably after cancel.
110 - Add all command line arguments to "update", e.g. slot=nn volStatus=append, ...
113 - Examine Bare Metal restore problem (a FD crash exists somewhere ...).
114 - Implement timeout in response() when it should come quickly.
115 - Implement console @echo command.
116 - Implement a Slot priority (loaded/not loaded).
117 - Implement "vacation" Incremental only saves.
118 - Implement single pane restore (much like the Gftp panes).
119 - Implement Automatic Mount even in operator wait.
120 - Implement create "FileSet"?
121 - Implement Release Device in the Job resource to unmount a drive.
122 - Implement Acquire Device in the Job resource to mount a drive,
123 be sure this works with admin jobs so that the user can get
124 prompted to insert the correct tape. Possibly some way to say to
125 run the job but don't save the files.
126 - Implement all command line args on run.
127 - Implement command line "restore" args.
128 - Implement "restore current select=no"
129 - Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
130 - Implement "scratch pool" where tapes are defined and can be
131 taken by any pool that needs them.
132 - Implement restore "current system", but take all files without
133 doing selection tree -- so that jobs without File records can
135 - Implement disk spooling. Two parts: 1. Spool to disk then
136 immediately to tape to speed up tape operations. 2. Spool to
137 disk only when the tape is full, then when a tape is hung move
139 - Implement a relocatable bacula.spec
140 - Implement dump/print label to UA
141 - Add prefixlinks to where or not where absolute links to FD.
142 - Issue message to mount a new tape before the rewind.
143 - Simplified client job initiation for portables.
144 - If SD cannot open a drive, make it periodically retry.
145 - Implement LabelTemplate (at least first cut).
146 - Add more of the config info to the tape label.
147 - Implement a Mount Command and an Unmount Command where
148 the users could specify a system command to be performed
149 to do the mount, after which Bacula could attempt to
150 read the device. This is for Removeable media such as a CDROM.
151 - Most likely, this mount command would be invoked explicitly
152 by the user using the current Console "mount" and "unmount"
153 commands -- the Storage Daemon would do the right thing
154 depending on the exact nature of the device.
155 - As with tape drives, when Bacula wanted a new removable
156 disk mounted, it would unmount the old one, and send a message
157 to the user, who would then use "mount" as described above
158 once he had actually inserted the disk.
160 - Make some way so that if a machine is skipped because it is not up
161 that Bacula will continue retrying for a specified period of time --
163 - If tape is marked read-only, then try opening it read-only rather than
164 failing, and remember that it cannot be written.
165 - Refine SD waiting output:
166 Device is being positioned
167 > Device is being positioned for append
168 > Device is being positioned to file x
170 - Figure out some way to estimate output size and to avoid splitting
171 a backup across two Volumes -- this could be useful for writing CDROMs
172 where you really prefer not to have it split -- not serious.
173 - Add RunBeforeJob and RunAfterJob to the Client program.
174 - Have SD compute MD5 or SHA1 and compare to what FD computes.
175 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
176 actual data on the Volume and compare it.
177 - Implement FileOptions (see end of this document)
178 - Implement Bacula plugins -- design API
179 - Make bcopy read through bad tape records.
180 - Fix read_record to handle multiple sessions.
181 - Program files (i.e. execute a program to read/write files).
182 Pass read date of last backup, size of file last time.
183 - Add Signature type to File DB record.
184 - CD into subdirectory when open()ing files for backup to
185 speed up things. Test with testfind().
186 - Priority job to go to top of list.
187 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
188 - Implement some way for the Console to dynamically create a job.
189 - Restore to a particular time -- e.g. before date, after date.
190 - Solaris -I on tar for include list
191 - Need a verbose mode in restore, perhaps to bsr.
192 - bscan without -v is too quiet -- perhaps show jobs.
193 - Add code to reject whole blocks if not wanted on restore.
194 - Check if we can increase Bacula FD priorty in Win2000
195 - Make sure the MaxVolFiles is fully implemented in SD
196 - Check if both CatalogFiles and UseCatalog are set to SD.
197 - Need return status on read_cb() from read_records(). Need multiple
198 records -- one per Job, maybe a JCR or some other structure with
199 a block and a record.
200 - Figure out how to do a bare metal Windows restore
201 - Possibly add email to Watchdog if drive is unmounted too
202 long and a job is waiting on the drive.
203 - Use read_record.c in SD code.
204 - Restore program that errors in SD due to no tape reports
205 OK incorrectly in output.
206 - After unmount, if restore job started, ask to mount.
207 - Convert all %x substitution variables, which are hard to remember
208 and read to %(variable-name). Idea from TMDA.
209 - Remove NextId for SQLite. Optimize.
210 - Move all SQL statements into a single location.
211 - Add UA rc and history files.
212 - put termcap (used by console) in ./configure and
213 allow -with-termcap-dir.
214 - Enhance time and size scanning routines.
215 - Fix Autoprune for Volumes to respect need for full save.
216 - Fix Win32 config file definition name on /install
217 - Compare tape to Client files (attributes, or attributes and data)
218 - Make all database Ids 64 bit.
219 - Write an applet for Linux.
220 - Add estimate to Console commands
221 - Implement new daemon communications protocol.
222 - Allow console commands to detach or run in background.
223 - Fix status delay on storage daemon during rewind.
224 - Add SD message variables to control operator wait time
225 - Maximum Operator Wait
226 - Minimum Message Interval
227 - Maximum Message Interval
228 - Send Operator message when cannot read tape label.
229 - Verify level=Volume (scan only), level=Data (compare of data to file).
230 Verify level=Catalog, level=InitCatalog
232 - Add keyword search to show command in Console.
233 - Events : tape has more than xxx bytes.
234 - Complete code in Bacula Resources -- this will permit
235 reading a new config file at any time.
236 - Handle ctl-c in Console
237 - Implement script driven addition of File daemon to config files.
238 - Think about how to make Bacula work better with File (non-tape) archives.
239 - Write Unix emulator for Windows.
240 - Put memory utilization in Status output of each daemon
241 if full status requested or if some level of debug on.
242 - Make database type selectable by .conf files i.e. at runtime

247 - Restore -- do nothing but show what would happen
248 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
249 - Implement Restore FileSet=
250 - Create a protocol.h and protocol.c where all protocol messages

254 - Concept of precious tapes (cannot be reused).
255 - Make bcopy copy with a single tape drive.
256 - Permit changing ownership during restore.
259 > My suggestion: Add a feature on the systray menu-icon menu to request

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

604 Request For Comments For File Backup Options
607 Subject: File Backup Options
610 A few days ago, a Bacula user who is backing up to file volumes and
611 using compression asked if it was possible to suppress compressing
612 all .gz files since it was a waste of CPU time. Although Bacula
613 currently permits using different options (compression, ...) on
614 a directory by directory basis, it cannot do it on a file by
615 file basis, which is clearly what was desired.
617 Proposed Implementation:
618 To solve this problem, I propose the following:
620 - Add a new Director resource type called FileOptions.
622 - The FileOptions resource will have records for all
623 options that can currently be specified on the Include record
624 (in a FileSet). Examples below.
626 - The FileOptions resource will permit an exclude option as well
627 as a number of additional options.
629 - The heart of the FileOptions resource is the ability to
630 supply any number of ApplyTo records which specify POSIX
631 regular expressions. These ApplyTo regular expressions are
632 applied to the fully qualified filename (path and all). If
633 one matches, then the FileOptions will be used.
635 - When an ApplyTo specification matches an included file, the
636 options specified in the FileOptions resource will override
637 the default options specified on the Include record.
639 - Include records will be modified to permit referencing one or
640 more FileOptions resources. The FileOptions will be used
641 in the order listed on the Include record and the first
642 one that matches will be applied.
644 - Options (or specifications) currently supplied on the Include
645 record will be deprecated (i.e. removed in a later version a
646 year or so from now).
648 - The Exclude record will be deprecated as the same functionality
649 can be obtained by using an Exclude = yes in the FileOptions.
652 The following records can appear in the FileOptions resource. An
653 asterisk preceding the name indicates a feature not currently
657 - Compression= (GZIP, ...)
658 - Signature= (MD5, SHA1, ...)
660 - OneFs= (yes/no) - remain on one filesystem
661 - Recurse= (yes/no) - recurse into subdirectories
662 - Sparse= (yes/no) - do sparse file backup
663 - *Exclude= (yes/no) - exclude file from being saved
664 - *Reader= (filename) - external read (backup) program
665 - *Plugin= (filename) - read/write plugin module
668 - verify= (ipnougsamc5) - verify options
671 - replace= (always/ifnewer/ifolder/never) - replace options currently
673 - *Writer= (filename) - external write (restore) program
677 Currently options specifying compression, MD5 signatures, recursion,
678 ... of a FileSet are supplied on the Include record. These will now
679 all be collected into a FileOptions resource, which will be
680 specified on the Include in place of the options. Multiple FileOptions
681 may be specified. Since the FileOptions contain regular expressions
682 that are applied to the full filename, this will give the ability
683 to specify backup options on a file by file basis to whatever level
692 Include = compression=GZIP signature=MD5 {
701 Include = FileOptions=Opts {
712 That's a lot more to do the same thing, but it gives the ability to
713 apply options on a file by file basis. For example, suppose you
714 want to compress all files but not any file with extensions .gz or .Z.
715 You could do so as follows:
719 Include = FileOptions=NoCompress FileOptions=Opts {
727 ApplyTo = /*.?*/ # matches all files
732 # Note multiple ApplyTos are ORed
733 ApplyTo = /*.gz/ # matches .gz files */
734 ApplyTo = /*.Z/ # matches .Z files */
737 Now, since the NoCompress FileOptions is specified first on the
738 Include line, any *.gz or *.Z file will have an MD5 signature computed,
739 but will not be compressed. For all other files, the NoCompress will not
740 match, so the Opts options will be used which will include GZIP
744 - Is it necessary to provide some means of ANDing regular expressions
745 and negation? (not currently planned)
747 e.g. ApplyTo = /*.gz/ && !/big.gz/
749 - I see that Networker has a "null" module which, if specified, does not
750 backup the file, but does make an record of the file in the catalog
751 so that the catalog will reflect an exact picture of the filesystem.
752 The result is that the file can be "seen" when "browsing" the save
753 sets, but it cannot be restored.
755 Is this really useful? Should it be implemented in Bacula?
758 After implementing the above, the user will be able to specify
759 on a file by file basis (using regular expressions) what options are
760 applied for the backup.
763 =============================================
765 ==========================================================
767 For each Incremental job that is run, there may be files that
768 were found but not saved because they were locked (this applies
769 only to Windows). Such a system could send back to the Director
770 a list of Unsaved files.
772 - New UnSavedFiles table that contains:
776 - Then in the next Incremental job, the list of Unsaved Files will be
777 feed to the FD, who will ensure that they are explicitly chosen even
778 if standard date/time check would not have selected them.
779 =============================================================

918 - When Marking a file in Restore that is a hard link, also
919 mark the link so that the data will be reloaded.
920 - Emergency restore info:
922 - Backup working directory
924 - Why don't we get an error message from Win32 FD when bootstrap
925 file cannot be created for restore command?
926 - Fix Win2000 error with no messages during startup.

938 - Implement Release Storage=xxx
939 - Fix restore on Win95/98
940 - Remove the Jmsg() in sql_find.c:102 or only print on hard error.
941 - Implement FileSet VolIndex -- done, but must update old records.
942 - Check this below from Phil.
943 This was SD reported data rather than FD data!
944 > When the job was done, Bacula reported 11084 files restored:

960 - Should Bacula make an Append tape as Purged when purging?
961 - Use switch() in backup.c and restore.c in FD instead of giant if statement.
962 - If during a restore, a hard linked file already exists (on option), delete
963 the file and re-link it. This is to avoid the possibility that the
964 user had re-linked the file between the backup and the restore.
965 Do lstat() to see if it is already properly linked.
966 Same for symlinked file.
967 Make sure ifnewer, ifolder, never, ... apply correctly.

977 thread, or set it in status.c cancel (used pthread_kill() instead of
979 - Add restore to specific date.
980 - Instrument use_count on DEVICE packets and ensure that the device is
981 being close()ed at the appropriate time.
982 - Test long path names (>64 chars) in Windows -- crashes FD?
983 - Implement fast block rejection: match_bsr_block().
984 - Complain if record dropped in bnet_recv because too long.
985 - Test multiple simultaneous Volumes
986 - Document recycling algorithm.
987 - Make Restore report an error if FD or SD term codes are not OK.
988 - To link with mysqlclient_r may require -lssl -lcrypto
989 - Document Heart beat code
990 - Non-fatal errors are not correct counting attribs.c:277
991 - Check that Block number in JobMedia are correct.

996 - Fix restore list of volumes if Volume not selected.
997 - Complete (or turn off) the command line code in update.

999 because there were a whole pile of jobs hanging around in the SD
1000 waiting for a connection from the FD that was never coming.
1001 - Possibly update all client records at startup.
1002 - Listing of Win32 restored files has ??????? for user.
1003 - In Win portable restore the directory is not create

1011 - Document c:/working directory better than /working directory.
1012 - Document run "yes".
1013 - Document update volume: jobid, current, before, all
1014 - Document that bscan does not work with multiple simultaneous jobs.
1015 - Update Automatic Volume Labeling in disk.wml
1016 - Figure out how to handle DHCP IP addresses -- use dynamic DNS.
