92 Bacula Projects Roadmap
94 last update 7 October 2002
96 Item 1: Multiple simultaneous Jobs. (done)
99 What: Permit multiple simultaneous jobs in Bacula.
101 Why: An enterprise level solution needs to go fast without the
102 need for the system administrator to carefully tweak
103 timing. Based on the benchmarks, during a full
104 backup, NetWorker typically hit 10 times the bandwidth to
105 the tape compared to Bacula--largely. This is probably due to
106 running parallel jobs and multi-threaded filling of buffers
107 and writing them to tape. This should also make things work
108 better when you have a mix of fast and slow machines backing
111 Notes: Bacula was designed to run multiple simultaneous jobs. Thus
112 implementing this is a matter of some small cleanups and
116 Item 2: Make the Storage daemon use intermediate file storage to buffer data.
117 Deferred -- not necessary yet.
119 What: If data is coming into the SD too fast, buffer it to
120 disk if the user has configured this option.
122 Why: This would be nice, especially if it more or less falls out
123 when implementing (1) above. If not, it probably should not
124 be given a high priority because fundamentally the backup time
125 is limited by the tape bandwidth. Even though you may finish a
126 client job quicker by spilling to disk, you still have to
127 eventually get it onto tape. If intermediate disk buffering
128 allows us to improve write bandwidth to tape, it may make
131 Notes: Whether or not this is implemented will depend upon performance
132 testing after item 1 is implemented.
135 Item 3: Write the bscan program.
138 What: Write a program that reads a Bacula tape and puts all the
139 appropriate data into the catalog. This allows recovery
140 from a tape that is no longer in the database, or it allows
141 re-creation of a database if lost.
143 Why: This is a fundamental robustness and disaster recovery tool
144 which will increase the comfort level of a sysadmin
145 considering adopting Bacula.
147 Notes: A skeleton of this program already exists, but much work
148 needs to be done. Implementing this will also make apparent
149 any deficiencies in the current Bacula tape format.
152 Item 4: Implement Base jobs.
154 What: A base job is sort of like a Full save except that you
155 will want the FileSet to contain only files that are unlikely
156 to change in the future (i.e. a snapshot of most of your
157 system after installing it). After the base job has been run,
158 when you are doing a Full save, you can specify to exclude
159 all files saved by the base job that have not been modified.
161 Why: This is something none of the competition does, as far as we know
162 (except BackupPC, which is a Perl program that saves to disk
163 only). It is big win for the user, it makes Bacula stand out
164 as offering a unique optimization that immediately saves time
167 Notes: Big savings in tape usage. Will require more resources because
168 the e. DIR must send FD a list of files/attribs, and the FD must
169 search the list and compare it for each file to be saved.
172 Item 5: Implement Label templates
174 What: This is a mechanism whereby Bacula can automatically create
175 a tape label for new tapes according to a detailed specification
176 provided by the user.
178 Why: It is a major convenience item for folks who use automated label
181 Notes: Bacula already has a working form of automatic tape label
182 creation, but it is very crude. The design for the complete
183 tape labeling project is already documented in the manual.
186 Item 6: Write a regression script.
189 What: This is an automatic script that runs and tests as many features
190 of Bacula as possible. The output is compared to previous
191 versions of Bacula and any differences are reported.
193 Why: This is an enormous help in preventing introduction of new
194 errors in parts of the program that already work correctly.
196 Notes: This probably should be ranked higher, it's something the typical
197 user doesn't see. Depending on how it's implemented, it may
198 make sense to defer it until the archival tape format and
199 user interface mature.
202 Item 7: GUI for interactive restore
203 Item 8: GUI for interactive backup
205 What: The current interactive restore is implemented with a tty
206 interface. It would be much nicer to be able to "see" the
207 list of files backed up in typical GUI tree format.
208 The same mechanism could also be used for creating
209 ad-hoc backup FileSets (item 8).
211 Why: Ease of use -- especially for the end user.
213 Notes: Rather than implementing in Gtk, we probably should go directly
214 for a Browser implementation, even if doing so meant the
215 capability wouldn't be available until much later. Not only
216 is there the question of Windows sites, most
217 Solaris/HP/IRIX, etc, shops can't currently run Gtk programs
218 without installing lots of stuff admins are very wary about.
219 Real sysadmins will always use the command line anyway, and
220 the user who's doing an interactive restore or backup of his
221 own files will in most cases be on a Windows machine running
225 Item 9: Add SSL to daemon communications.
227 What: This provides for secure communications between the daemons.
229 Why: This would allow doing backup across the Internet without
230 privacy concerns (or with much less concern).
232 Notes: The vast majority of near term potential users will be backing up
233 a single site over a LAN and, correctly or not, they probably
234 won't be concerned with security, at least not enough to go to
235 the trouble to set up keys, etc. to screw things down. We suspect
236 that many users genuinely interested in multi-site backup
237 already run some form of VPN software in their internetwork
238 connections, and are willing to delegate security to that layer.
241 Item 10: Define definitive tape format.
242 Mostly done (version 1.27)
244 What: Define that definitive tape format that will not change
245 for the next millennium.
247 Why: Stability, security.
249 Notes: See notes for item 11 below.
252 Item 11: New daemon communication protocol.
254 What: The current daemon to daemon protocol is basically an ASCII
255 printf() and sending the buffer. On the receiving end, the
256 buffer is sscanf()ed to unpack it. The new scheme would
257 be a binary format that allows quick packing and unpacking
258 of any data type with named fields.
260 Why: Using binary packing would be faster. Named fields will permit
261 error checking to ensure that what is sent is what the
262 receiver really wants.
264 Notes: These are internal improvements in the interest of the
265 long-term stability and evolution of the program. On the one
266 hand, the sooner they're done, the less code we have to rip
267 up when the time comes to install them. On the other hand, they
268 don't bring an immediately perceptible benefit to potential
269 users. Item 10 and possibly item 11 should be deferred until Bacula
270 is well established with a growing user community more or
271 less happy with the feature set. At that time, it will make a
272 good "next generation" upgrade in the interest of data
277 I haven't put these in any particular order.
280 - Rework Storage daemon with new rwl_lock routines.

397 - Remove duplicate fields from jcr (e.g. jcr.level and
399 - Timout a job or terminate if link goes down, or reopen link and query.
400 - Define how we handle times to avoid problem with Unix dates (2049 ?).
401 - Fill all fields in Vol/Job Header -- ensure that everything
402 needed is written to tape. Think about restore to Catalog
403 from tape. Client record needs improving.
404 - Find general solution for sscanf size problems (as well
405 as sprintf. Do at run time?
407 - Concept of precious tapes (cannot be reused).
408 - Allow FD to run from inetd ???

491 - Enhance Jmsg code to permit buffering and saving to disk.
492 - device driver = "xxxx" for drives.
493 - restart: paranoid: read label fsf to
494 eom read append block, and go
495 super-paranoid: read label, read all files
496 in between, read append block, and go
497 verify: backspace, read append block, and go
498 permissive: same as above but frees drive
499 if tape is not valid.
501 - Ensure that /dev/null works
502 - File daemon should build list of files skipped, and then
503 at end of save retry and report any errors.
504 - Need report class for messages. Perhaps
505 report resource where report=group of messages
507 - enhance scan_attrib and rename scan_jobtype, and
508 fill in code for "since" option
509 - To buffer messages, we need associated jobid and Director name.
510 - Need to save contents of FileSet to tape?
511 - Director needs a time after which the report status is sent
512 anyway -- or better yet, a retry time for the job.
513 Don't reschedule a job if previous incarnation is still running.
514 - Figure out how to save the catalog (possibly a special FileSet).
515 - Figure out how to restore the catalog.
516 - Figure out how to put a Volume into the catalog (from the tape)
517 - Figure out how to do a restore from a Volume
518 - Some way to automatically backup everything is needed????
519 - Need a structure for pending actions:
521 - termination status (part of buffered msgs?)
522 - Concept of grouping Storage devices and job can use
523 any of a number of devices
525 Read, Write, Clean, Delete
526 - Login to Bacula; Bacula users with different permissions:
528 - Tape recycle destination
529 - Job Schedule Status
533 - File daemon should pass Director the operating system info
534 to be stored in the Client Record (or verified that it has
536 - Store info on each file system type (probably in the job header on tape.
537 This could be the output of df; or perhaps some sort of /etc/mtab record.
540 - Use media 1 time (so that we can do 6 days of incremental
541 backups before switching to another tape) (already)
542 specify # times (jobs)
543 specify bytes (already)
544 specify time (seconds, hours, days)
545 - Implement FSM (File System Modules).
546 - Identify unchanged or "system" files and save them to a
547 special tape thus removing them from the standard
548 backup FileSet -- BASE backup.
549 - Turn virutally all sprintfs into snprintfs.
550 - Heartbeat between daemons.
551 - Audit M_ error codes to ensure they are correct and consistent.
552 - Add variable break characters to lex analyzer.
553 Either a bit mask or a string of chars so that
554 the caller can change the break characters.
555 - Make a single T_BREAK to replace T_COMMA, etc.
556 - Ensure that File daemon and Storage daemon can
557 continue a save if the Director goes down (this
558 is NOT currently the case). Must detect socket error,
559 buffer messages for later.
562 Done: (see kernsdone for more)
565 - Check if GZIP1 is working -- check speed.
