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

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

471 fl = fcntl(sockfd, F_GETFL);
472 fcntl(sockfd, F_SETFL, fl & (~ O_NONBLOCK) & (~ O_NDELAY));
474 - Enhance Jmsg code to permit buffering and saving to disk.
475 - device driver = "xxxx" for drives.
476 - restart: paranoid: read label fsf to
477 eom read append block, and go
478 super-paranoid: read label, read all files
479 in between, read append block, and go
480 verify: backspace, read append block, and go
481 permissive: same as above but frees drive
482 if tape is not valid.
484 - Ensure that /dev/null works
485 - File daemon should build list of files skipped, and then
486 at end of save retry and report any errors.
487 - Need report class for messages. Perhaps
488 report resource where report=group of messages
490 - enhance scan_attrib and rename scan_jobtype, and
491 fill in code for "since" option
492 - To buffer messages, we need associated jobid and Director name.
493 - Need to save contents of FileSet to tape?
494 - Director needs a time after which the report status is sent
495 anyway -- or better yet, a retry time for the job.
496 Don't reschedule a job if previous incarnation is still running.
497 - Figure out how to save the catalog (possibly a special FileSet).
498 - Figure out how to restore the catalog.
499 - Figure out how to put a Volume into the catalog (from the tape)
500 - Figure out how to do a restore from a Volume
501 - Some way to automatically backup everything is needed????
502 - Need a structure for pending actions:
504 - termination status (part of buffered msgs?)
505 - Concept of grouping Storage devices and job can use
506 any of a number of devices
508 Read, Write, Clean, Delete
509 - Login to Bacula; Bacula users with different permissions:
511 - Tape recycle destination
512 - Job Schedule Status
516 - File daemon should pass Director the operating system info
517 to be stored in the Client Record (or verified that it has
519 - Store info on each file system type (probably in the job header on tape.
520 This could be the output of df; or perhaps some sort of /etc/mtab record.
523 - Use media 1 time (so that we can do 6 days of incremental
524 backups before switching to another tape) (already)
525 specify # times (jobs)
526 specify bytes (already)
527 specify time (seconds, hours, days)
528 - Implement FSM (File System Modules).
529 - Identify unchanged or "system" files and save them to a
530 special tape thus removing them from the standard
531 backup FileSet -- BASE backup.
532 - Turn virutally all sprintfs into snprintfs.
533 - Heartbeat between daemons.
534 - Audit M_ error codes to ensure they are correct and consistent.
535 - Add variable break characters to lex analyzer.
536 Either a bit mask or a string of chars so that
537 the caller can change the break characters.
538 - Make a single T_BREAK to replace T_COMMA, etc.
539 - Ensure that File daemon and Storage daemon can
540 continue a save if the Director goes down (this
541 is NOT currently the case). Must detect socket error,
542 buffer messages for later.
545 Done: (see kernsdone for more)
546 --the console script is broken as installed and has to be hand-massaged with
547 paths, config files etc.
548 - Termination status in FD for Verify = C -- incorrect.
549 - Implement alter_sqlite_tables
550 - Fix scheduler -- see "Hourly cycle". It doesn't do both each
551 hour, rather it alternates between 0:05 and 0:35.
552 - Create Counter DB records.
553 - Fix db_get_job_volume_names() to return array of strings (now works
555 - Eliminate MySQL shared libraries from smtp and daemons not using MySQL.
556 - Compare tape File attributes to Catalog.
557 (File attributes are size, dates, MD5, but not
559 - Report bad status from smtp or mail program.
560 - Ensure that Start/End File/Block are correct.
561 - If MySQL database is not running, job terminates with
562 wierd type and wierd error code.
563 - Probably create a jcr with JobId=0 as a master
564 catchall if jcr not found or if operation involves
566 - The daemons should know when one is already
567 running and refuse to run a second copy.
568 - Figure out how to do a "full" restore from catalog
569 - Make SD send attribute stream to DR but first
570 buffering to file, then sending only when the
571 files are written to tape.
572 - Restore file xx or files xx, yy to their most recent values.
573 - Get correct block/file information in Catalog, pay attention to change of media.
574 - Write better dump of Messages resource.
575 - Authentication between SD and FD
576 - In restore job, print some summary information at end, such
577 as rate, ... job status, ...
578 - Problem with len at 362 in tree.c
579 - Report volume write rate.
580 - Pass "Catalog Files = no" to storage daemon to eliminate network traffic.
581 - When we are at EOM, we must ask each job to write JobMedia
582 record (update_volume_info).
