8 Data encryption Meno Abels (see projects)
9 Communication encryption Meno Abels
10 Version 1.35 Kern (see below)
11 ========================================================
13 1.35 Items to do for release:
15 - Add bscan to four-concurrent-jobs regression.
17 - Add IPv6 to regression
18 - Do tape alerts -- see tapealert.txt
19 - Document a get out of jail procedure if everything breaks if
20 you lost/broke the Catalog -- do the same for "I know my
21 file is there how do I get it back?".
22 - When passwords do not match, print message that points the
24 - Make Verify jobs require exclusive use of Volume as Restore
26 - Perhaps add read/write programs and/or plugins to FileSets.
27 - Look at adding Client run command that will use the
28 port opened by the client.
29 - Fix find_device in stored/dircmd.c:462
30 - Add new DCR calling sequences everywhere in SD.
31 This will permit simultaneous use of multiple
32 devices by a single job.
33 - bscan does not put first of two volumes back with all info in
35 - Fix restore ++++ that get intermingled with "Building directory tree"
36 - Solve the termcap.h problem on Solaris configure.
37 - Fix ./configure to handle installed SQLite
38 - Test Win32 errno handling.
42 Documentation to do: (any release a little bit at a time)
43 - Document query file format.
44 - Document problems with Verify and pruning.
45 - Document how to use multiple databases.
46 - VXA drives have a "cleaning required"
47 indicator, but Exabyte recommends preventive cleaning after every 75
50 In this context, it should be noted that Exabyte has a command-line
51 vxatool utility available for free download. (The current version is
52 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
53 test the drive, unload tapes, change drive settings, flash new firmware,
55 Of particular interest in this context is that vxatool <device> -i will
56 report, among other details, the time since last cleaning in tape motion
57 minutes. This information can be retrieved (and settings changed, for
58 that matter) through the generic-SCSI device even when Bacula has the
59 regular tape device locked. (Needless to say, I don't recommend
60 changing tape settings while a job is running.)
61 - Lookup HP cleaning recommendations.
62 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
63 - Add more obvious documentation of @ for conf files.
64 - Document doing table repair
66 Testing to do: (painful)
68 - blocksize recognition code.
69 - Test if rewind at end of tape waits for tape to rewind.
72 For 1.37 Testing/Documentation:
73 - Add db check test to regression. Test each function like delete,
75 - If you use restore replace=never, the directory attributes for
76 non-existent directories will not be restored properly.
79 - Implement the FreeBSD nodump flag in chflags.
80 - Figure out how to make named console messages go only to that
81 console and to the non-restricted console (new console class?).
82 - Make restricted console prompt for password if *ask* is set or
83 perhaps if password is undefined.
84 - Implement "from ISO-date/time every x hours/days/weeks/months" in
86 ==== from Marc Schoechlin
87 - the help-command should be more verbose
88 (it should explain the paramters of the different
90 -> it´s time-comsuming to consult the manual anytime
91 you need a special parameter
92 -> maybe it´s more easy to maintain this, if the
93 descriptions of that commands are outsourced to
95 - the cd-command should allow complete paths
96 i.e. cd /foo/bar/foo/bar
97 -> if a customer mails me the path to a certain file,
98 it´s faster to enter the specified directory
99 - if the password is not configured in bconsole.conf
100 you should be asked for it.
101 -> sometimes you like to do restore on a customer-machine
102 which shouldn´t know the password for bacula.
103 -> adding the password to the file favours admins
104 to forget to remove the password after usage
106 the protection of that file is less important
107 - long-listed-output of commands should be scrollable
108 like the unix more/less-command does
109 -> if someone runs 200 and more machines, the lists could
110 be a little long and complex
111 - command-output should be shown column by column
112 to reduce scrolling and to increase clarity
114 - lsmark should list the selected files with full
116 - wildcards for selecting and file and directories would be nice
117 - any actions should be interuptable with STRG+C
118 - command-expansion would be pretty cool
120 - Compaction of Disk space by "migrating" Volumes that have pruned
121 Jobs (what criteria? size, #jobs, time).
122 - Add prune all command
123 - Document fact that purge can destroy a part of a restore by purging
124 one volume while others remain valid -- perhaps mark Jobs.
125 - Add multiple-media-types.txt
126 - look at mxt-changer.html
127 - Make ? do a help command (no return needed).
128 - Implement restore directory.
129 - Add All Local Partitions = yes to new style saves.
130 - Document streams and how to implement them.
131 - Possibly implement "Ensure Full Backup = yes" looks for a failed full backup
132 and upgrades the current backup if one exists.
133 - Check that barcode reading and update slots scan works.
134 - Try not to re-backup a file if a new hard link is added.
135 - Add feature to backup hard links only, but not the data.
136 - Add "All Local = yes" option to save to include all local partitions.
137 - Fix stream handling to be simpler.
138 - Add Priority and Bootstrap to Run a Job.
139 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
141 - Remove View FileSet button from Run a Job dialog.
142 - Don't count higher level non-saved directories in Files expected
144 - Handle prompt for restore job at end of Restore command.
145 - Add display of total selected files to Restore window.
146 - Add tree pane to left of window.
147 - Add progress meter.
148 - Polling does not work for restore. It tries a number of times,
149 gives up, and crashes the SD.
150 - Lock jcr_chain when doing attach/detach in acquire.c
151 - Add assert in free_jcr if attach/detach chain active.
152 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
153 - Document writing to a CD/DVD with Bacula.
154 - Add check for tape alerts.
155 - Add a "base" package to the window installer for pthreadsVCE.dll
156 which is needed by all packages.
157 - Add message to user to check for fixed block size when the forward
158 space test fails in btape.
159 - When unmarking a directory check if all files below are unmarked and
160 then remove the + flag -- in the restore tree.
161 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
162 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
163 - Revisit the question of multiple Volumes (disk) on a single device.
164 - Finish SIGHUP work.
165 - Check that all change in wait status in the SD are
166 signaled to the Director.
167 - Add a block copy option to bcopy.
168 - Investigate adding Mac Resource Forks.
169 - Finish work on Gnome restore GUI.
170 - Fix "llist jobid=xx" where no fileset or client exists.
171 - Check pruning of restore jobs.
173 it seems to be complaining about 12:00pm which should be a valid 12
174 hour time. I changed the time to 11:59am and everything works fine.
175 Also 12:00am works fine. 0:00pm also works (which I don't think
176 should). None of the values 12:00pm - 12:59pm work for that matter.
177 - Add level to estimate command.
178 - For each job type (Admin, Restore, ...) require only the really necessary
180 - Fix option 2 of restore -- list where file is backed up -- require Client,
181 then list last 20 backups.
182 - Add all pools in Dir conf to DB also update them to catch changed
183 LabelFormats and such.
184 - Update volumes FromPool=xxx does all volumes.
185 - Pass Director resource name as an option to the Console.
186 - Add a "batch" mode to the Console (no unsolicited queries, ...).
187 - Add code to check for tape alerts -- tapeinfo.
188 - Make sure list of Volumes needed is in correct order for restore.
190 - Remove paths (and files that reference them) that have no trailing slash
191 in dbcheck -- or add a trailing slash.
192 - Remove Filenames (and files that reference them) that have a trailing
193 slash in dbcheck -- or remove the trailing slash.
194 - Remove orphaned paths/filenames by copying them to a new table with a
195 reference count, then mark all referenced files/paths and remove unreferenced
197 - Add a .list all files in the restore tree (probably also a list all files)
198 Do both a long and short form.
199 - Allow browsing the catalog to see all versions of a file (with
200 stat data on each file).
201 - Restore attributes of directory if replace=never set but directory
203 - Allow "delete job jobid=xxx,yyy,aaa-bbb" i.e. list + ranges.
204 - Use SHA1 on authentication if possible.
205 - See comtest-xxx.zip for Windows code to talk to USB.
206 - Make btape accept Device Names in addition to Archive names.
207 - Add Events and Perl scripting.
208 - Add John's appended files:
209 Appended = { /files/server/logs/http/*log }
210 and such files would be treated as follows.On a FULL backup, they would
211 be backed up like any other file.On an INCREMENTAL backup, where a
212 previous INCREMENTAL or FULL was already in thecatalogue and the length
213 of the file wasgreater than the length of the last backup, only thedata
214 added since the last backup will be dumped.On an INCREMENTAL backup, if
215 the length of the file is less than thelength of the file with the same
216 name last backed up, the completefile is dumped.On Windows systems, with
217 creation date of files, we can be evensmarter about this and not count
218 entirely upon the length.On a restore, the full and all incrementals
219 since it will beapplied in sequence to restore the file.
220 - Add a regression test for dbcheck.
221 - Add disk seeking on restore. - Allow
222 for optional cancelling of SD and FD in case DIR
223 gets a fatal error. Requested by Jesse Guardiani <jesse@wingnet.net>
224 - Bizarre message: Error: Could not open WriteBootstrap file:
225 - Build console in client only build.
226 - Add "limit=n" for "list jobs"
227 - Check new HAVE_WIN32 open bits.
228 - Check if the tape has moved before writing.
229 - Handling removable disks -- see below:
230 - Multiple drive autochanger support -- see below.
231 - Keep track of tape use time, and report when cleaning is necessary.
232 - Fix FreeBSD mt_count problem.
233 - Add FromClient and ToClient keywords on restore command (or
234 BackupClient RestoreClient).
235 - Automatic "update slots" on user configuration directive when a
237 - Implement a JobSet, which groups any number of jobs. If the
238 JobSet is started, all the jobs are started together.
239 Allow Pool, Level, and Schedule overrides.
240 - Enhance cancel to timeout BSOCK packets after a specific delay.
241 - When I restore to Windows the Created, Accessed and Modifiedtimes are
242 those of the time of the restore, not those of the originalfile.
243 The dates you will find in your restore log seem to be the original
245 - Volume "add"ed to Pool gets recycled in first use. VolBytes=0
246 - If a tape is recycled while it is mounted, Stanislav Tvrudy must do an
247 additional mount to deblock the job.
249 bscan: sql_update.c:65 UPDATE File SET MD5='Ij+5kwN6TFIxK+8l8+/I+A' WHERE FileId=0
250 bscan: bscan.c:1074 Could not add MD5/SHA1 to File record. ERR=sql_update.c:65 Update problem: affected_rows=0
251 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
252 ua_status.!!! Thanks to Alan Brown for this tip.
253 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
254 correctly for multiple simultaneous jobs.
255 - Correct code so that FileSet MD5 is calculated for < and | filename
257 - Mark Volume in error on error from WEOF.
258 - Implement the Media record flag that indicates that the Volume does disk
260 - Implement VolAddr, which is used when Volume is addressed like a disk,
261 and form it from VolFile and VolBlock.
262 - Make multiple restore jobs for multiple media types specifying
263 the proper storage type.
264 - Implement MediaType keyword in bsr?
265 - Fix fast block rejection (stored/read_record.c:118). It passes a null
266 pointer (rec) to try_repositioning().
267 - Look at extracting Win data from BackupRead.
268 - Having dashes in filenames apparently creates problems for restore
269 by filename??? hard to believe.
270 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
271 which would take precidence over the Catalog "JobRetention".
272 - Implement Label Format in Add and Label console commands.
273 - Possibly up network buffers to 65K. Put on variable.
274 - Put email tape request delays on one or more variables. User wants
275 to cancel the job after a certain time interval. Maximum Mount Wait?
276 - Job, Client, Device, Pool, or Volume?
277 Is it possible to make this a directive which is *optional* in multiple
278 resources, like Level? If so, I think I'd make it an optional directive
279 in Job, Client, and Pool, with precedence such that Job overrides Client
280 which in turn overrides Pool.
281 - Print a message when a job starts if the conf file is not current.
283 - Spooling ideas taken from Volker Sauer's and other's emails:
284 > IMHO job spooling should be turned on
290 > where and 2) overrides 1) and 3) is independent.
292 Yes, this is the minimum that I think is necessary.
296 > It should be switched by job, because the job that backs up the machine
297 > with the bacula-sd on doesn't need spooling.
298 > It should be switched by schedule, because for full-backups I don't need
299 > spooling, so I can switch it off (because the network faster then the
302 True, with the exception that if you have enough disk spool space,
303 and you want to run concurrent jobs, spooling can eliminate the block
304 interleaving restore inefficiencies.
306 > And you should be able to turn it of by sd for sd-machines with low disk
307 > capacity or if you just don't need or want this feature.
310 > - definitly the possibility for multipe spool direcories
312 Having multiple directories is no problem -- having different maximum
313 sizes creates specification problems. At some point, I will probably
314 have a common SD pool of spool directories as well as a set of
315 private spool directories for each device. The first implementation
316 will be a set of private spool directories for each device since
317 managing a global pool with a bunch of threads writing into the same
318 directory is *much* more complicated and prone to error.
320 > - the ability to spool parts of a backup (not the whole client)
322 This may change in the future, but for the moment, it will spool
323 either to a job high water mark, or until the directory is full
324 (reaches max spool size or I/O error). It will then write to tape,
325 truncate the spool file, and begin spooling again.
327 > - spooling while writing to tape
329 Not within a job, but yes, if you run concurrent jobs -- each is a
330 different thread. Within a job could be a feature, but *much* later.
332 > - parallel spooling (like parallel jobs/ concurrent jobs) of clients
334 Yes, this is one of my main motivations for doing it (aside from
335 eliminating tape "shoe shine" during incremental backups.
337 > - flushing a backup that only went to disk (like amflush in amanda)
339 This will be a future feature, since spooling is different from backing
340 up to disk. The future feature will be "migration" which will move a job
341 from one backup Volume to another.
343 - New Storage specifications:
344 Passed to SD as a sort of BSR record called Storage Specification
348 MediaType -> Next MediaType
350 Device -> Next Device
351 Write Copy Resource that makes a copy of a resource.
353 Allow multiple Storage specifications
361 Allow Multiple Pool specifications (note, Pool currently
363 Allow Multiple MediaType specifications
364 Allow Multiple Device specifications
365 Perhaps keep this in a single SSR
366 Tie a Volume to a specific device by using a MediaType that
367 is contained in only one device.
368 In SD allow Device to have Multiple MediaTypes
371 - Look at www.nu2.nu/pebuilder as a helper for full windows
373 Ideas from Jerry Scharf:
374 First let's point out some big pluses that bacula has for this
376 more importantly it's active. Thank you so much for that
377 even more important, it's not flaky
378 it has an open access catalog, opening many possibilities
379 it's pushing toward heterogeneous systems capability
381 I don't remember an include file directive for config files
382 (not filesets, actual config directives)
383 can you check the configs without starting the daemon?
384 some warnings about possible common mistakes
386 doing the testing and blessing of concurrent backup writes
387 this is absolutely necessary in the enterprise
388 easy user recovery GUI with full access checking
389 Macintosh file client
390 macs are an interesting niche, but I fear a server is a rathole
391 working bare iron recovery for windows
392 much better handling on running config changes
393 thinking through the logic of what happens to jobs in progress
394 the option for inc/diff backups not reset on fileset revision
395 a) use both change and inode update time against base time
396 b) do the full catalog check (expensive but accurate)
397 sizing guide (how much system is needed to back up N systems/files)
398 consultants on using bacula in building a disaster recovery system
400 or how to get at fancy things that one could do with bacula
401 logwatch code for bacula logs (or similar)
402 linux distro inclusion of bacula (brings good and bad, but necessary)
403 win2k/XP server capability (icky but you asked)
404 support for Oracle database ??
406 - Look at adding SQL server and Exchange support for Windows.
407 - Restore: Enter Filename: 'C:/Documents and Settings/Comercial/My
408 Documents/MOP/formulário de registro BELAS ARTES.doc' causes Bacula to
410 - Each DVD-RAM disk would be a volume, just like each tape is
411 a volume. It's a 4.7GB media with random access, but there's nothing about
412 it that I can see that makes it so different than a tape from bacula's
413 perspective. Why couldn't I back up to a bare floppy as a volume (ignoring
415 - Make dev->file and dev->block_num signed integers so that -1 can
416 be an invalid value which happens with BSR.
417 - Create VolAddr for disk files in place of VolFile and VolBlock. This
418 is needed to properly specify ranges.
419 - Print bsmtp output to job report so that problems will be seen.
420 - Pass the number of files to be restored to the FD for reporting
421 - Add progress of files/bytes to SD and FD.
422 - Don't continue Restore if no files selected.
423 - Print warning message if FileId > 4 billion
424 - do a "messages" before the first prompt in Console
425 - Add a date and time stamp at the beginning of every line in the
426 Job report (Volker Sauer).
427 - Client does not show busy during Estimate command.
428 - Implement Console mtx commands.
429 - Add a default DB password to MySQL.
430 GRANT all privileges ON bacula.* TO bacula@localhost IDENTIFIED BY
433 - Implement a Mount Command and an Unmount Command where
434 the users could specify a system command to be performed
435 to do the mount, after which Bacula could attempt to
436 read the device. This is for Removeable media such as a CDROM.
437 - Most likely, this mount command would be invoked explicitly
438 by the user using the current Console "mount" and "unmount"
439 commands -- the Storage Daemon would do the right thing
440 depending on the exact nature of the device.
441 - As with tape drives, when Bacula wanted a new removable
442 disk mounted, it would unmount the old one, and send a message
443 to the user, who would then use "mount" as described above
444 once he had actually inserted the disk.
445 - Implement dump/print label to UA
446 - Implement disk spooling. Two parts: 1. Spool to disk then
447 immediately to tape to speed up tape operations. 2. Spool to
448 disk only when the tape is full, then when a tape is hung move
450 - Scratch Pool where the volumes can be re-assigned to any Pool.
451 - bextract is sending everything to the log file ****FIXME****
452 - Add Progress command that periodically reports the progress of
454 - Restrict characters permitted in a Resource name, and don't permit
456 - Allow multiple Storage specifications (or multiple names on
457 a single Storage specification) in the Job record. Thus a job
458 can be backed up to a number of storage devices.
459 - Implement some way for the File daemon to contact the Director
460 to start a job or pass its DHCP obtained IP number.
461 - Implement multiple Consoles.
462 - Implement a query tape prompt/replace feature for a console
464 Two jobs ready to go, first one blocked waiting for media
465 Cancel 2nd job ("waiting execution" one)
468 - Copy console @ code to gnome2-console
469 - Make AES the only encryption algorithm see
470 http://csrc.nist.gov/CryptoToolkit/aes/). It's
471 an officially adopted standard, has survived peer
472 review, and provides keys up to 256 bits.
473 - Think about how space could be freed up on a tape -- perhaps this
474 is a Merge or Compact feature that is needed.
475 - Modify FileSet, did not upgrade the current Increment job, but
476 waited for the next job to be upgraded.
477 - Take a careful look at SetACL http://setacl.sourceforge.net
478 - Implement a where command for the tree telling where a file
480 - Take a careful look at Level for the estimate command, maybe make
481 it a command line option.
482 - Add Volume name to "I cannot write on this volume because"
483 - Make tree walk routines like cd, ls, ... more user friendly
484 by handling spaces better.
485 - Write your PID file and chown root:wheel before drop.
486 - Make sure there is no symlink in a file before creating a
488 - Look at mktemp or mkstemp(3).
489 mktemp and mkstemp create files with predictable names too. That's
490 not the vulnerability. The vulnerability is in creating files without
491 using the O_EXCL flag, which means "only create this file if it doesn't
492 exist, including if the file is a dangling symlink."
494 It is *NOT* enough to do the equivalent of
496 if doesn't exist $filename
497 then create $filename
499 because between the test and the create another process could have
500 gotten the CPU and created the file. You must use atomic functions
501 (those that don't get interrupted by other processes) and O_EXCL is
502 the only way for this particular example.
503 - Automatically create pools, but instead of looking for what
504 in in Job records, walk through the pool resources.
505 - Check and double check tree code, why does it take so long?
506 - Add device name to "Current Volume not acceptable because ..."
507 - Make sure that Bacula rechecks the tape after the 20 min wait.
508 - Set IO_NOWAIT on Bacula TCP/IP packets.
509 - Try doing a raw partition backup and restore by mounting a
512 Yes, it would allow to highly automatic the request for new tapes. If a
513 tape is empty, bacula reads the barcodes (native or simulated), and if
514 an unused tape is found, it runs the label command with all the
515 necessary parameters.
517 By the way can bacula automatically "move" an empty/purged volume say
518 in the "short" pool to the "long" pool if this pool runs out of volume
520 - Eliminate orphaned jobs: dbcheck, normal pruning, delete job command.
521 Hm. Well, there are the remaining orphaned job records:
523 | 105 | Llioness Save | 0000-00-00 00:00:00 | B | D | 0 | 0 | f |
524 | 110 | Llioness Save | 0000-00-00 00:00:00 | B | I | 0 | 0 | f |
525 | 115 | Llioness Save | 2003-09-10 02:22:03 | B | I | 0 | 0 | A |
526 | 128 | Catalog Save | 2003-09-11 03:53:32 | B | I | 0 | 0 | C |
527 | 131 | Catalog Save | 0000-00-00 00:00:00 | B | I | 0 | 0 | f |
529 As you can see, three of the five are failures. I already deleted the
530 one restore and one other failure using the by-client option. Deciding
531 what is an orphaned job is a tricky problem though, I agree. All these
532 records have or had 0 files/ 0 bytes, except for the restore. With no
533 files, of course, I don't know of the job ever actually becomes
534 associated with a Volume.
536 (I'm not sure if this is documented anywhere -- what are the meanings of
537 all the possible JobStatus codes?)
539 Looking at my database, it appears to me as though all the "orphaned"
540 jobs fit into one of two categories:
542 1) The Job record has a StartTime but no EndTime, and the job is not
545 2) The Job record has an EndTime, indicating that it completed, but
546 it has no associated JobMedia record.
549 This does suggest an approach. If failed jobs (or jobs that, for some
550 other reason, write no files) are associated with a volume via a
551 JobMedia record, then they should be purged when the associated volume
552 is purged. I see two ways to handle jobs that are NOT associated with a
555 1) purge them automatically whenever any volume is manually purged;
557 2) add an option to the purge command to manually purge all jobs with
558 no associated volume.
560 I think Restore jobs also fall into category 2 above .... so one might
561 want to make that "The Job record has an EndTime,, but no associated
562 JobMedia record, and is not a Restore job."
563 - make "btape /tmp" work.
564 - Make sure a rescheduled job is properly reported by status.
565 - Walk through the Pool records rather than the Job records
566 in dird.c to create/update pools.
567 - What to do about "list files job=xxx".
568 - When job rescheduled, status gives is waiting for Client Rufus
569 to connect to Storage File. Dir needs to inform SD that job
571 - Make Dmsg look at global before calling subroutine.
572 - Enable trace output at runtime for Win32
573 - Available volumes for autochangers (see patrick@baanboard.com 3 Sep 03
574 and 4 Sep) scan slots.
575 - Get and test MySQL 4.0
576 - Do a complete audit of all pthreads_mutex, cond, ... to ensure that
577 any that are dynamically initialized are destroyed when no longer used.
578 - Look at how fuser works and /proc/PID/fd that is how Nic found the
579 file descriptor leak in Bacula.
580 - Implement WrapCounters in Counters.

585 - Can we dynamically change FileSets?
586 - If pool specified to label command and Label Format is specified,
587 automatically generate the Volume name.
588 - Why can't SQL do the filename sort for restore?
589 - Look at libkse (man kse) for FreeBSD threading.
590 - Look into Microsoft Volume Shadowcopy Service VSS for backing
591 up system state components (Active Directory, System Volume, ...)
592 - Add ExhautiveRestoreSearch
593 - Look at the possibility of loading only the necessary
594 data into the restore tree (i.e. do it one directory at a
595 time as the user walks through the tree).
596 - Possibly use the hash code if the user selects all for a restore command.
597 - Orphaned Dir buffer at parse_conf.c:373 => store_dir
598 - Fix "restore all" to bypass building the tree.
599 - Prohibit backing up archive device (findlib/find_one.c:128)
600 - Implement Release Device in the Job resource to unmount a drive.
601 - Implement Acquire Device in the Job resource to mount a drive,
602 be sure this works with admin jobs so that the user can get
603 prompted to insert the correct tape. Possibly some way to say to
604 run the job but don't save the files.
605 - Implement FileOptions (see end of this document)
606 - Make things like list where a file is saved case independent for
609 - Bacula needs to propagate SD errors.

621 so that an autochanger can be made to work.
622 - User wants to NOT backup up certain big files (email files).
623 - Maybe remove multiple simultaneous devices code in SD.
624 - On Windows with very long path names, it may be impossible to create
625 a file (and thus restore it) because the total length is too long.
626 We must cd into the directory then create the file without the
628 - lstat() is not going to work on Win32 for testing date.
629 - Implement a Recycle command
630 - Add client name to cram-md5 challenge so Director can immediately
631 verify if it is the correct client.
632 - Add JobLevel in FD status (but make sure it is defined).
633 - Audit all UA commands to ensure that we always prompt where possible.
634 - Check Jmsg in bnet, may not work, must dup bsock.
635 - Suppress Job Name in Jmsg for console
636 - Create Pools that are referenced in a Run statement at startup if possible.

638 then the next job run gets an error reading the drive.
639 - Make bootstrap filename unique.
640 - Test a second language e.g. french.
641 - Start working on Base jobs.
642 - Make "make binary-release" work from any directory.
643 - Implement UnsavedFiles DB record.
644 - Implement argc/argv for daemon command line scanning using table driven
646 - Implement table driven single argc/argv scanner to pickup all arguments.
647 Much like xxx_conf.c scan table.
648 keyword, handler(store_routine), store_address, code, flags, default.
649 - From Phil Stracchino:
650 It would probably be a per-client option, and would be called
651 something like, say, "Automatically purge obsoleted jobs". What it
652 would do is, when you successfully complete a Differential backup of a
653 client, it would automatically purge all Incremental backups for that
654 client that are rendered redundant by that Differential. Likewise,
655 when a Full backup on a client completed, it would automatically purge
656 all Differential and Incremental jobs obsoleted by that Full backup.
657 This would let people minimize the number of tapes they're keeping on
658 hand without having to master the art of retention times.
659 - Implement a M_SECURITY message class.
660 - When doing a Backup send all attributes back to the Director, who
661 would then figure out what files have been deleted.
662 - Currently in mount.c:236 the SD simply creates a Volume. It should have
663 explicit permission to do so. It should also mark the tape in error
664 if there is an error.
665 - Make sure all restore counters are working correctly in the FD.
666 - SD Bytes Read is wrong.
667 - Look at ALL higher level routines that call block.c to be sure
668 they don't expect something in errmsg.
669 - Investigate doing RAW backup of Win32 partition.
670 - Add thread specific data to hold the jcr -- send error messages from
671 low level routines by accessing it and using Jmsg().
672 - Cancel waiting for Client connect in SD if FD goes away.
674 - Examine Bare Metal restore problem (a FD crash exists somewhere ...).
675 - Implement timeout in response() when it should come quickly.
676 - Implement console @echo command.
677 - Implement a Slot priority (loaded/not loaded).
678 - Implement "vacation" Incremental only saves.
679 - Implement single pane restore (much like the Gftp panes).
680 - Implement Automatic Mount even in operator wait.
681 - Implement create "FileSet"?
682 - Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
683 - Implement "scratch pool" where tapes are defined and can be
684 taken by any pool that needs them.
685 - Implement restore "current system", but take all files without
686 doing selection tree -- so that jobs without File records can
688 - Add prefixlinks to where or not where absolute links to FD.
689 - Issue message to mount a new tape before the rewind.
690 - Simplified client job initiation for portables.
691 - If SD cannot open a drive, make it periodically retry.
692 - Add more of the config info to the tape label.
694 - If tape is marked read-only, then try opening it read-only rather than
695 failing, and remember that it cannot be written.
696 - Refine SD waiting output:
697 Device is being positioned
698 > Device is being positioned for append
699 > Device is being positioned to file x
701 - Figure out some way to estimate output size and to avoid splitting
702 a backup across two Volumes -- this could be useful for writing CDROMs
703 where you really prefer not to have it split -- not serious.
704 - Have SD compute MD5 or SHA1 and compare to what FD computes.
705 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
706 actual data on the Volume and compare it.
707 - Implement Bacula plugins -- design API
708 - Make bcopy read through bad tape records.
709 - Program files (i.e. execute a program to read/write files).
710 Pass read date of last backup, size of file last time.
711 - Add Signature type to File DB record.
712 - CD into subdirectory when open()ing files for backup to
713 speed up things. Test with testfind().
714 - Priority job to go to top of list.
715 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
716 - Implement some way for the Console to dynamically create a job.
717 - Restore to a particular time -- e.g. before date, after date.
718 - Solaris -I on tar for include list
719 - Need a verbose mode in restore, perhaps to bsr.
720 - bscan without -v is too quiet -- perhaps show jobs.
721 - Add code to reject whole blocks if not wanted on restore.
722 - Check if we can increase Bacula FD priorty in Win2000
723 - Make sure the MaxVolFiles is fully implemented in SD
724 - Check if both CatalogFiles and UseCatalog are set to SD.
725 - Figure out how to do a bare metal Windows restore
726 - Possibly add email to Watchdog if drive is unmounted too
727 long and a job is waiting on the drive.
728 - Restore program that errs in SD due to no tape, reports
729 OK incorrectly in output.
730 - After unmount, if restore job started, ask to mount.
731 - Convert all %x substitution variables, which are hard to remember
732 and read to %(variable-name). Idea from TMDA.
733 - Remove NextId for SQLite. Optimize.
734 - Move all SQL statements into a single location.
735 - Add UA rc and history files.
736 - put termcap (used by console) in ./configure and
737 allow -with-termcap-dir.
738 - Fix Autoprune for Volumes to respect need for full save.
739 - Fix Win32 config file definition name on /install
740 - Compare tape to Client files (attributes, or attributes and data)
741 - Make all database Ids 64 bit.
742 - Write an applet for Linux.
743 - Allow console commands to detach or run in background.
744 - Fix status delay on storage daemon during rewind.
745 - Add SD message variables to control operator wait time
746 - Maximum Operator Wait
747 - Minimum Message Interval
748 - Maximum Message Interval
749 - Send Operator message when cannot read tape label.
750 - Verify level=Volume (scan only), level=Data (compare of data to file).
751 Verify level=Catalog, level=InitCatalog
753 - Add keyword search to show command in Console.
754 - Events : tape has more than xxx bytes.
755 - Complete code in Bacula Resources -- this will permit
756 reading a new config file at any time.
757 - Handle ctl-c in Console
758 - Implement script driven addition of File daemon to config files.
759 - Think about how to make Bacula work better with File (non-tape) archives.

773 - Concept of precious tapes (cannot be reused).
774 - Make bcopy copy with a single tape drive.
775 - Permit changing ownership during restore.

789 - Autolabel should be specified by DIR instead of SD.
792 - AutoScan (check checksum of tape)
793 - Format command = "format /dev/nst0"
797 - Seek resolution (usually corresponds to buffer size)
798 - EODErrorCode=ENOSPC or code
799 - Partial Read error code
800 - Partial write error code
801 - Nonformatted read error
802 - Nonformatted write error
803 - WriteProtected error
807 - IgnoreCloseErrors=yes
817 - FD sends unsaved file list to Director at end of job (see
819 - File daemon should build list of files skipped, and then
820 at end of save retry and report any errors.
821 - Write a Storage daemon that uses pipes and
822 standard Unix programs to write to the tape.
824 - Need something that monitors the JCR queue and
825 times out jobs by asking the deamons where they are.
826 - Enhance Jmsg code to permit buffering and saving to disk.
827 - device driver = "xxxx" for drives.
829 - Ensure that /dev/null works
830 - Need report class for messages. Perhaps
831 report resource where report=group of messages
832 - enhance scan_attrib and rename scan_jobtype, and
833 fill in code for "since" option
834 - Director needs a time after which the report status is sent
835 anyway -- or better yet, a retry time for the job.
836 - Don't reschedule a job if previous incarnation is still running.
837 - Some way to automatically backup everything is needed????
838 - Need a structure for pending actions:
840 - termination status (part of buffered msgs?)
842 Read, Write, Clean, Delete
843 - Login to Bacula; Bacula users with different permissions:
844 owner, group, user, quotas
845 - Store info on each file system type (probably in the job header on tape.
846 This could be the output of df; or perhaps some sort of /etc/mtab record.
849 - Design at hierarchial storage for Bacula. Migration and Clone.
850 - Implement FSM (File System Modules).
851 - Audit M_ error codes to ensure they are correct and consistent.
852 - Add variable break characters to lex analyzer.
853 Either a bit mask or a string of chars so that
854 the caller can change the break characters.
855 - Make a single T_BREAK to replace T_COMMA, etc.
856 - Ensure that File daemon and Storage daemon can
857 continue a save if the Director goes down (this
858 is NOT currently the case). Must detect socket error,
859 buffer messages for later.
860 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
861 - Add ability to backup to two Storage devices (two SD sessions) at
862 the same time -- e.g. onsite, offsite.
863 - Add the ability to consolidate old backup sets (basically do a restore
864 to tape and appropriately update the catalog). Compress Volume sets.
865 Might need to spool via file is only one drive is available.
866 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
867 someway to do so with every volume that has less than x% valid
871 Migration: Move a backup from one Volume to another
872 Clone: Copy a backup -- two Volumes
874 Bacula Migration is based on Jobs (apparently Networker is file by file).
876 Migration triggered by:
880 Highwater mark (keep total size)
885 ======================================================
887 It is somewhat like a Full save becomes an incremental since
888 the Base job (or jobs) plus other non-base files.
890 - A Base backup is same as Full backup, just different type.
891 - New BaseFiles table that contains:
893 BaseJobId - Base JobId referenced for this FileId (needed ???)
894 JobId - JobId currently running
895 FileId - File not backed up, exists in Base Job
896 FileIndex - FileIndex from Base Job.
897 i.e. for each base file that exists but is not saved because
898 it has not changed, the File daemon sends the JobId, BaseId,
899 FileId, FileIndex back to the Director who creates the DB entry.
900 - To initiate a Base save, the Director sends the FD
901 the FileId, and full filename for each file in the Base.
902 - When the FD finds a Base file, he requests the Director to
903 send him the full File entry (stat packet plus MD5), or
904 conversely, the FD sends it to the Director and the Director
905 says yes or no. This can be quite rapid if the FileId is kept
906 by the FD for each Base Filename.
907 - It is probably better to have the comparison done by the FD
908 despite the fact that the File entry must be sent across the
910 - An alternative would be to send the FD the whole File entry
911 from the start. The disadvantage is that it requires a lot of
912 space. The advantage is that it requires less communications
914 - The Job record must be updated to indicate that one or more
916 - At end of Job, FD returns:
917 1. Count of base files/bytes not written to tape (i.e. matches)
918 2. Count of base file that were saved i.e. had changed.
919 - No tape record would be written for a Base file that matches, in the
920 same way that no tape record is written for Incremental jobs where
921 the file is not saved because it is unchanged.
922 - On a restore, all the Base file records must explicitly be
923 found from the BaseFile tape. I.e. for each Full save that is marked
924 to have one or more Base Jobs, search the BaseFile for all occurrences
926 - An optimization might be to make the BaseFile have:
932 This would avoid the need to explicitly fetch each File record for
933 the Base job. The Base Job record will be fetched to get the
934 VolSessionId and VolSessionTime.
935 =========================================================
938 ==========================================================
940 For each Incremental job that is run, there may be files that
941 were found but not saved because they were locked (this applies
942 only to Windows). Such a system could send back to the Director
943 a list of Unsaved files.
945 - New UnSavedFiles table that contains:
949 - Then in the next Incremental job, the list of Unsaved Files will be
950 feed to the FD, who will ensure that they are explicitly chosen even
951 if standard date/time check would not have selected them.
952 =============================================================
955 Done: (see kernsdone for more)
958 - John's Full save failed with 1.32c FD and 1.31 Dir no FD status,
959 and no error message.
960 - Add fd and st as Console keywords.
961 - Recycling volume with a Slot requires an operator intervention:
962 rufus-dir: Start Backup JobId 18, Job=kernsave.2003-11-01_21.23.52
963 rufus-dir: Pruned 1 Job on Volume Vol01 from catalog.
964 rufus-dir: There are no Jobs associated with Volume Vol01. Marking it purged.
965 rufus-dir: Recycled volume "Vol01"
966 rufus-sd: Please mount Volume "Vol01" on Storage Device "DDS-4" for Job kernsave.2003-11-01_21.23.52
967 Use "mount" command to release Job.
968 - Implement Dan's bacula script (email of 26 Oct).
969 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
970 - Edit the Client/Storage name into authentication failure messages.
971 - Fix packet too big problem. This is most likely a Windows TCP stack
973 - Implement ClientRunBeforeJob and ClientRunAfterJob.
974 - Implement forward spacing block/file: position_device(bsr) --
975 just before read_block_from_device();

1018 There needs to be a table of drive # to devices somewhere - If there are
1019 multiple changers or drives there may not be a 1:1 correspondance between
1020 changer drive number and system device name - and depending on the way the
1021 drives are hooked up to scsi busses, they may not be linearly numbered
1022 from an offset point either.something like
1024 Autochanger drives = 2
1025 Autochanger drive 0 = /dev/nst1
1026 Autochanger drive 1 = /dev/nst2
1027 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1028 times, not just for multidrive changers. For a 1 drive changer, that's
1034 MTX's manpage (1.2.15):
1035 unload [<slotnum>] [ <drivenum> ]
1036 Unloads media from drive <drivenum> into slot
1037 <slotnum>. If <drivenum> is omitted, defaults to
1038 drive 0 (as do all commands). If <slotnum> is
1039 omitted, defaults to the slot that the drive was
1040 loaded from. Note that there's currently no way
1041 to say 'unload drive 1's media to the slot it
1042 came from', other than to explicitly use that
1043 slot number as the destination.AB

1081 Handling removable disks
1083 From: Karl Cunningham <karlc@keckec.com>
1085 My backups are only to hard disk these days, in removable bays. This is my
1086 idea of how a backup to hard disk would work more smoothly. Some of these
1087 things Bacula does already, but I mention them for completeness. If others
1088 have better ways to do this, I'd like to hear about it.
1090 1. Accommodate several disks, rotated similar to how tapes are. Identified
1091 by partition volume ID or perhaps by the name of a subdirectory.
1092 2. Abort & notify the admin if the wrong disk is in the bay.
1093 3. Write backups to different subdirectories for each machine to be backed
1095 4. Volumes (files) get created as needed in the proper subdirectory, one
1097 5. When a disk is recycled, remove or zero all old backup files. This is
1098 important as the disk being recycled may be close to full. This may be
1099 better done manually since the backup files for many machines may be
1100 scattered in many subdirectories.
