Below, you will find more information on future projects:
-Item 1: Implement Migration that moves Jobs from one Pool to another.
+Item 1: Implement data encryption (as opposed to comm encryption)
+ Date: 28 October 2005
+ Origin: Sponsored by Landon and 13 contributors to EFF.
+ Status: Done: Landon Fuller has implemented this in 1.39.x.
+
+ What: Currently the data that is stored on the Volume is not
+ encrypted. For confidentiality, encryption of data at
+ the File daemon level is essential.
+ Data encryption encrypts the data in the File daemon and
+ decrypts the data in the File daemon during a restore.
+
+ Why: Large sites require this.
+
+Item 2: Implement Migration that moves Jobs from one Pool to another.
Origin: Sponsored by Riege Software International GmbH. Contact:
Daniel Holtkamp <holtkamp at riege dot com>
Date: 28 October 2005
- Status: Partially coded in 1.37 -- much more to do. Assigned to
+ Status: 90% complete: Working in 1.39, more to do. Assigned to
Kern.
What: The ability to copy, move, or archive data that is on a
Number of Jobs
Number of Volumes
+Item 3: Accurate restoration of renamed/deleted files from
+ Incremental/Differential backups
+ Date: 28 November 2005
+ Origin: Martin Simmons (martin at lispworks dot com)
+ Status:
-Item 2: Implement extraction of Win32 BackupWrite data.
- Origin: Thorsten Engel <thorsten.engel at matrix-computer dot com>
- Date: 28 October 2005
- Status: Assigned to Thorsten. Implemented in current CVS
+ What: When restoring a fileset for a specified date (including "most
+ recent"), Bacula should give you exactly the files and directories
+ that existed at the time of the last backup prior to that date.
- What: This provides the Bacula File daemon with code that
- can pick apart the stream output that Microsoft writes
- for BackupWrite data, and thus the data can be read
- and restored on non-Win32 machines.
+ Currently this only works if the last backup was a Full backup.
+ When the last backup was Incremental/Differential, files and
+ directories that have been renamed or deleted since the last Full
+ backup are not currently restored correctly. Ditto for files with
+ extra/fewer hard links than at the time of the last Full backup.
- Why: BackupWrite data is the portable=no option in Win32
- FileSets, and in previous Baculas, this data could
- only be extracted using a Win32 FD. With this new code,
- the Windows data can be extracted and restored on
- any OS.
+ Why: Incremental/Differential would be much more useful if this worked.
+
+ Notes: Item 14 (Merging of multiple backups into a single one) seems to
+ rely on this working, otherwise the merged backups will not be
+ truly equivalent to a Full backup.
+
+ Kern: notes shortened. This can be done without the need for
+ inodes. It is essentially the same as the current Verify job,
+ but one additional database record must be written, which does
+ not need any database change.
+ Kern: see if we can correct restoration of directories if
+ replace=ifnewer is set. Currently, if the directory does not
+ exist, a "dummy" directory is created, then when all the files
+ are updated, the dummy directory is newer so the real values
+ are not updated.
-Item 3: Implement a Bacula GUI/management tool using Python.
+Item 4: Implement a Bacula GUI/management tool using Python.
Origin: Kern
Date: 28 October 2005
- Status:
+ Status: Lucus is working on this for Python GTK+.
What: Implement a Bacula console, and management tools
using Python and Qt or GTK.
Notes: This is currently being implemented using Python-GTK by
Lucas Di Pentima <lucas at lunix dot com dot ar>
-
-Item 4: Implement a Python interface to the Bacula catalog.
- Date: 28 October 2005
- Origin: Kern
- Status:
-
- What: Implement an interface for Python scripts to access
- the catalog through Bacula.
-
- Why: This will permit users to customize Bacula through
- Python scripts.
-
-Item 5: Implement more Python events in Bacula.
- Date: 28 October 2005
- Origin:
- Status:
-
- What: Allow Python scripts to be called at more places
- within Bacula and provide additional access to Bacula
- internal variables.
-
- Why: This will permit users to customize Bacula through
- Python scripts.
-
- Notes: Recycle event
- Scratch pool event
- NeedVolume event
- MediaFull event
-
- Also add a way to get a listing of currently running
- jobs (possibly also scheduled jobs).
-
-
-Item 6: Implement Base jobs.
+Item 5: Implement Base jobs.
Date: 28 October 2005
Origin: Kern
Status:
FD a list of files/attribs, and the FD must search the
list and compare it for each file to be saved.
-Item 7: Add Plug-ins to the FileSet Include statements.
- Date: 28 October 2005
- Origin:
- Status: Partially coded in 1.37 -- much more to do.
-
- What: Allow users to specify wild-card and/or regular
- expressions to be matched in both the Include and
- Exclude directives in a FileSet. At the same time,
- allow users to define plug-ins to be called (based on
- regular expression/wild-card matching).
-
- Why: This would give the users the ultimate ability to control
- how files are backed up/restored. A user could write a
- plug-in knows how to backup his Oracle database without
- stopping/starting it, for example.
-
-Item 8: Implement huge exclude list support using hashing.
- Date: 28 October 2005
- Origin: Kern
- Status:
-
- What: Allow users to specify very large exclude list (currently
- more than about 1000 files is too many).
-
- Why: This would give the users the ability to exclude all
- files that are loaded with the OS (e.g. using rpms
- or debs). If the user can restore the base OS from
- CDs, there is no need to backup all those files. A
- complete restore would be to restore the base OS, then
- do a Bacula restore. By excluding the base OS files, the
- backup set will be *much* smaller.
-
-
-Item 9: Implement data encryption (as opposed to comm encryption)
- Date: 28 October 2005
- Origin: Sponsored by Landon and 13 contributors to EFF.
- Status: Landon Fuller is currently implementing this.
-
- What: Currently the data that is stored on the Volume is not
- encrypted. For confidentiality, encryption of data at
- the File daemon level is essential.
- Data encryption encrypts the data in the File daemon and
- decrypts the data in the File daemon during a restore.
-
- Why: Large sites require this.
-
-Item 10: Permit multiple Media Types in an Autochanger
- Origin: Kern
- Status: Now implemented
-
- What: Modify the Storage daemon so that multiple Media Types
- can be specified in an autochanger. This would be somewhat
- of a simplistic implementation in that each drive would
- still be allowed to have only one Media Type. However,
- the Storage daemon will ensure that only a drive with
- the Media Type that matches what the Director specifies
- is chosen.
-
- Why: This will permit user with several different drive types
- to make full use of their autochangers.
-
-Item 11: Allow different autochanger definitions for one autochanger.
- Date: 28 October 2005
- Origin: Kern
- Status:
-
- What: Currently, the autochanger script is locked based on
- the autochanger. That is, if multiple drives are being
- simultaneously used, the Storage daemon ensures that only
- one drive at a time can access the mtx-changer script.
- This change would base the locking on the control device,
- rather than the autochanger. It would then permit two autochanger
- definitions for the same autochanger, but with different
- drives. Logically, the autochanger could then be "partitioned"
- for different jobs, clients, or class of jobs, and if the locking
- is based on the control device (e.g. /dev/sg0) the mtx-changer
- script will be locked appropriately.
-
- Why: This will permit users to partition autochangers for specific
- use. It would also permit implementation of multiple Media
- Types with no changes to the Storage daemon.
-
-Item 12: Implement red/black binary tree routines.
- Date: 28 October 2005
- Origin: Kern
- Status:
+Item 6: Allow FD to initiate a backup
+ Origin: Frank Volf (frank at deze dot org)
+ Date: 17 November 2005
+ Status:
- What: Implement a red/black binary tree class. This could
- then replace the current binary insert/search routines
- used in the restore in memory tree. This could significantly
- speed up the creation of the in memory restore tree.
+ What: Provide some means, possibly by a restricted console that
+ allows a FD to initiate a backup, and that uses the connection
+ established by the FD to the Director for the backup so that
+ a Director that is firewalled can do the backup.
- Why: Performance enhancement.
+ Why: Makes backup of laptops much easier.
-Item 13: Improve Baculas tape and drive usage and cleaning management.
+Item 7: Improve Bacula's tape and drive usage and cleaning management.
Date: 8 November 2005, November 11, 2005
Origin: Adam Thornton <athornton at sinenomine dot net>,
Arno Lehmann <al at its-lehmann dot de>
sub-projects: Measuring Tape and Drive usage, retiring
volumes, and handling drive cleaning and TAPEALERTs.
+Item 8: Implement creation and maintenance of copy pools
+ Date: 27 November 2005
+ Origin: David Boyes (dboyes at sinenomine dot net)
+ Status:
+
+ What: I would like Bacula to have the capability to write copies
+ of backed-up data on multiple physical volumes selected
+ from different pools without transferring the data
+ multiple times, and to accept any of the copy volumes
+ as valid for restore.
+
+ Why: In many cases, businesses are required to keep offsite
+ copies of backup volumes, or just wish for simple
+ protection against a human operator dropping a storage
+ volume and damaging it. The ability to generate multiple
+ volumes in the course of a single backup job allows
+ customers to simple check out one copy and send it
+ offsite, marking it as out of changer or otherwise
+ unavailable. Currently, the library and magazine
+ management capability in Bacula does not make this process
+ simple.
+
+ Restores would use the copy of the data on the first
+ available volume, in order of copy pool chain definition.
+
+ This is also a major scalability issue -- as the number of
+ clients increases beyond several thousand, and the volume
+ of data increases, transferring the data multiple times to
+ produce additional copies of the backups will become
+ physically impossible due to transfer speed
+ issues. Generating multiple copies at server side will
+ become the only practical option.
+
+ How: I suspect that this will require adding a multiplexing
+ SD that appears to be a SD to a specific FD, but 1-n FDs
+ to the specific back end SDs managing the primary and copy
+ pools. Storage pools will also need to acquire parameters
+ to define the pools to be used for copies.
+
+ Notes: I would commit some of my developers' time if we can agree
+ on the design and behavior.
+
+Item 9: Implement new {Client}Run{Before|After}Job feature.
+ Date: 26 September 2005
+ Origin: Phil Stracchino
+ Status: Done. This has been implemented by Eric Bollengier
+
+ What: Some time ago, there was a discussion of RunAfterJob and
+ ClientRunAfterJob, and the fact that they do not run after failed
+ jobs. At the time, there was a suggestion to add a
+ RunAfterFailedJob directive (and, presumably, a matching
+ ClientRunAfterFailedJob directive), but to my knowledge these
+ were never implemented.
+
+ The current implementation doesn't permit to add new feature easily.
+
+ An alternate way of approaching the problem has just occurred to
+ me. Suppose the RunBeforeJob and RunAfterJob directives were
+ expanded in a manner like this example:
+
+ RunScript {
+ Command = "/opt/bacula/etc/checkhost %c"
+ RunsOnClient = No # default
+ AbortJobOnError = Yes # default
+ RunsWhen = Before
+ }
+ RunScript {
+ Command = c:/bacula/systemstate.bat
+ RunsOnClient = yes
+ AbortJobOnError = No
+ RunsWhen = After
+ RunsOnFailure = yes
+ }
+
+ RunScript {
+ Command = c:/bacula/deletestatefile.bat
+ Target = rico-fd
+ RunsWhen = Always
+ }
+
+ It's now possible to specify more than 1 command per Job.
+ (you can stop your database and your webserver without a script)
+
+ ex :
+ Job {
+ Name = "Client1"
+ JobDefs = "DefaultJob"
+ Write Bootstrap = "/tmp/bacula/var/bacula/working/Client1.bsr"
+ FileSet = "Minimal"
+
+ RunBeforeJob = "echo test before ; echo test before2"
+ RunBeforeJob = "echo test before (2nd time)"
+ RunBeforeJob = "echo test before (3rd time)"
+ RunAfterJob = "echo test after"
+ ClientRunAfterJob = "echo test after client"
+
+ RunScript {
+ Command = "echo test RunScript in error"
+ Runsonclient = yes
+ RunsOnSuccess = no
+ RunsOnFailure = yes
+ RunsWhen = After # never by default
+ }
+ RunScript {
+ Command = "echo test RunScript on success"
+ Runsonclient = yes
+ RunsOnSuccess = yes # default
+ RunsOnFailure = no # default
+ RunsWhen = After
+ }
+ }
+
+ Why: It would be a significant change to the structure of the
+ directives, but allows for a lot more flexibility, including
+ RunAfter commands that will run regardless of whether the job
+ succeeds, or RunBefore tasks that still allow the job to run even
+ if that specific RunBefore fails.
+
+ Notes: (More notes from Phil, Kern, David and Eric)
+ I would prefer to have a single new Resource called
+ RunScript.
+
+ RunsWhen = After|Before|Always
+ RunsAtJobLevels = All|Full|Diff|Inc # not yet implemented
+
+ The AbortJobOnError, RunsOnSuccess and RunsOnFailure directives
+ could be optional, and possibly RunWhen as well.
+
+ AbortJobOnError would be ignored unless RunsWhen was set to Before
+ and would default to Yes if omitted.
+ If AbortJobOnError was set to No, failure of the script
+ would still generate a warning.
+
+ RunsOnSuccess would be ignored unless RunsWhen was set to After
+ (or RunsBeforeJob set to No), and default to Yes.
+
+ RunsOnFailure would be ignored unless RunsWhen was set to After,
+ and default to No.
+
+ Allow having the before/after status on the script command
+ line so that the same script can be used both before/after.

+Item 11: Deletion of Disk-Based Bacula Volumes
+ Date: Nov 25, 2005
+ Origin: Ross Boylan <RossBoylan at stanfordalumni dot org> (edited
+ by Kern)
+ Status:
- What: After a configurable amount of fatal errors with a tape drive
- Bacula should automatically disable further use of a certain
- tape drive. There should also be "disable"/"enable" commands in
- the "bconsole" tool.
+ What: Provide a way for Bacula to automatically remove Volumes
+ from the filesystem, or optionally to truncate them.
+ Obviously, the Volume must be pruned prior removal.
- Why: On a multi-drive jukebox there is a possibility of tape drives
- going bad during large backups (needing a cleaning tape run,
- tapes getting stuck). It would be advantageous if Bacula would
- automatically disable further use of a problematic tape drive
- after a configurable amount of errors has occurred.
+ Why: This would allow users more control over their Volumes and
+ prevent disk based volumes from consuming too much space.
- An example: I have a multi-drive jukebox (6 drives, 380+ slots)
- where tapes occasionally get stuck inside the drive. Bacula will
- notice that the "mtx-changer" command will fail and then fail
- any backup jobs trying to use that drive. However, it will still
- keep on trying to run new jobs using that drive and fail -
- forever, and thus failing lots and lots of jobs... Since we have
- many drives Bacula could have just automatically disabled
- further use of that drive and used one of the other ones
- instead.
+ Notes: The following two directives might do the trick:
+ Volume Data Retention = <time period>
+ Remove Volume After = <time period>
-Item 16: Directive/mode to backup only file changes, not entire file
+ The migration project should also remove a Volume that is
+ migrated. This might also work for tape Volumes.

- Status: RFC
+ Status:
What: Currently when a file changes, the entire file will be backed up in

Notes: This would require the usage of disk-based volumes as comparing
files would not be feasible using a tape drive.

+Item 13: Multiple threads in file daemon for the same job
+ Date: 27 November 2005
+ Origin: Ove Risberg (Ove.Risberg at octocode dot com)
Status:
- What: In the Bacula implementation a backup is finished after all data
- and attributes are successfully written to storage. When using a
- tape backup it is very annoying that a backup can take a day,
- simply because the current tape (or whatever) is full and the
- administrator has not put a new one in. During that time the
- system cannot be taken off-line, because there is still an open
- session between the storage daemon and the file daemon on the
- client.
+ What: I want the file daemon to start multiple threads for a backup
+ job so the fastest possible backup can be made.
- Although this is a very good strategy for making "safe backups"
- This can be annoying for e.g. laptops, that must remain
- connected until the backup is completed.
+ The file daemon could parse the FileSet information and start
+ one thread for each File entry located on a separate
+ filesystem.
- Using a new feature called "migration" it will be possible to
- spool first to harddisk (using a special 'spool' migration
- scheme) and then migrate the backup to tape.
+ A configuration option in the job section should be used to
+ enable or disable this feature. The configuration option could
+ specify the maximum number of threads in the file daemon.
- There is still the problem of getting the attributes committed.
- If it takes a very long time to do, with the current code, the
- job has not terminated, and the File daemon is not freed up. The
- Storage daemon should release the File daemon as soon as all the
- file data and all the attributes have been sent to it (the SD).
- Currently the SD waits until everything is on tape and all the
- attributes are transmitted to the Director before signaling
- completion to the FD. I don't think I would have any problem
- changing this. The reason is that even if the FD reports back to
- the Dir that all is OK, the job will not terminate until the SD
- has done the same thing -- so in a way keeping the SD-FD link
- open to the very end is not really very productive ...
+ If the theads could spool the data to separate spool files
+ the restore process will not be much slower.
- Why: Makes backup of laptops much easier.
+ Why: Multiple concurrent backups of a large fileserver with many
+ disks and controllers will be much faster.
+
+ Notes: I am willing to try to implement this but I will probably
+ need some help and advice. (No problem -- Kern)
+
+Item 14: Implement red/black binary tree routines.
+ Date: 28 October 2005
+ Origin: Kern
+ Status: Class code is complete. Code needs to be integrated into
+ restore tree code.
+ What: Implement a red/black binary tree class. This could
+ then replace the current binary insert/search routines
+ used in the restore in memory tree. This could significantly
+ speed up the creation of the in memory restore tree.
+
+ Why: Performance enhancement.

- If the theads could spool the data to separate spool files
- the restore process will not be much slower.

-Item 23: Deletion of Disk-Based Bacula Volumes
- Date: Nov 25, 2005
- Origin: Ross Boylan <RossBoylan at stanfordalumni dot org> (edited
- by Kern)
- Status:
+ What: Allow users to specify wild-card and/or regular
+ expressions to be matched in both the Include and
+ Exclude directives in a FileSet. At the same time,
+ allow users to define plug-ins to be called (based on
+ regular expression/wild-card matching).
- What: Provide a way for Bacula to automatically remove Volumes
- from the filesystem, or optionally to truncate them.
- Obviously, the Volume must be pruned prior removal.
+ Why: This would give the users the ultimate ability to control
+ how files are backed up/restored. A user could write a
+ plug-in knows how to backup his Oracle database without
+ stopping/starting it, for example.
- Why: This would allow users more control over their Volumes and
- prevent disk based volumes from consuming too much space.
+Item 20: Implement more Python events in Bacula.
+ Date: 28 October 2005
+ Origin:
+ Status:
- Notes: The following two directives might do the trick:
+ What: Allow Python scripts to be called at more places
+ within Bacula and provide additional access to Bacula
+ internal variables.
- Volume Data Retention = <time period>
- Remove Volume After = <time period>
+ Why: This will permit users to customize Bacula through
+ Python scripts.
- The migration project should also remove a Volume that is
- migrated. This might also work for tape Volumes.
+ Notes: Recycle event
+ Scratch pool event
+ NeedVolume event
+ MediaFull event
+
+ Also add a way to get a listing of currently running

-Item 24: Accurate restoration of renamed/deleted files from
- Incremental/Differential backups
- Date: 28 November 2005
- Origin: Martin Simmons (martin at lispworks dot com)
+Item 21: Quick release of FD-SD connection after backup.
+ Origin: Frank Volf (frank at deze dot org)
+ Date: 17 November 2005
Status:
- What: When restoring a fileset for a specified date (including "most
- recent"), Bacula should give you exactly the files and directories
- that existed at the time of the last backup prior to that date.
+ What: In the Bacula implementation a backup is finished after all data
+ and attributes are successfully written to storage. When using a
+ tape backup it is very annoying that a backup can take a day,
+ simply because the current tape (or whatever) is full and the
+ administrator has not put a new one in. During that time the
+ system cannot be taken off-line, because there is still an open
+ session between the storage daemon and the file daemon on the
+ client.
- Currently this only works if the last backup was a Full backup.
- When the last backup was Incremental/Differential, files and
- directories that have been renamed or deleted since the last Full
- backup are not currently restored correctly. Ditto for files with
- extra/fewer hard links than at the time of the last Full backup.
+ Although this is a very good strategy for making "safe backups"
+ This can be annoying for e.g. laptops, that must remain
+ connected until the backup is completed.
- Why: Incremental/Differential would be much more useful if this worked.
+ Using a new feature called "migration" it will be possible to
+ spool first to harddisk (using a special 'spool' migration
+ scheme) and then migrate the backup to tape.
- Notes: Item 14 (Merging of multiple backups into a single one) seems to
- rely on this working, otherwise the merged backups will not be
- truely equivalent to a Full backup.
+ There is still the problem of getting the attributes committed.
+ If it takes a very long time to do, with the current code, the
+ job has not terminated, and the File daemon is not freed up. The
+ Storage daemon should release the File daemon as soon as all the
+ file data and all the attributes have been sent to it (the SD).
+ Currently the SD waits until everything is on tape and all the
+ attributes are transmitted to the Director before signaling
+ completion to the FD. I don't think I would have any problem
+ changing this. The reason is that even if the FD reports back to
+ the Dir that all is OK, the job will not terminate until the SD
+ has done the same thing -- so in a way keeping the SD-FD link
+ open to the very end is not really very productive ...
- Kern: notes shortened. This can be done without the need for
- inodes. It is essentially the same as the current Verify job,
- but one additional database record must be written, which does
- not need any database change.
+ Why: Makes backup of laptops much easier.
-Item 25: Implement creation and maintenance of copy pools
- Date: 27 November 2005
- Origin: David Boyes (dboyes at sinenomine dot net)
- Status:
+Item 22: Permit multiple Media Types in an Autochanger
+ Origin: Kern
+ Status: Done. Implemented in 1.38.9 (I think).
- What: I would like Bacula to have the capability to write copies
- of backed-up data on multiple physical volumes selected
- from different pools without transferring the data
- multiple times, and to accept any of the copy volumes
- as valid for restore.
+ What: Modify the Storage daemon so that multiple Media Types
+ can be specified in an autochanger. This would be somewhat
+ of a simplistic implementation in that each drive would
+ still be allowed to have only one Media Type. However,
+ the Storage daemon will ensure that only a drive with
+ the Media Type that matches what the Director specifies
+ is chosen.
- Why: In many cases, businesses are required to keep offsite
- copies of backup volumes, or just wish for simple
- protection against a human operator dropping a storage
- volume and damaging it. The ability to generate multiple
- volumes in the course of a single backup job allows
- customers to simple check out one copy and send it
- offsite, marking it as out of changer or otherwise
- unavailable. Currently, the library and magazine
- management capability in Bacula does not make this process
- simple.
+ Why: This will permit user with several different drive types
+ to make full use of their autochangers.
- Restores would use the copy of the data on the first
- available volume, in order of copy pool chain definition.
+Item 23: Allow different autochanger definitions for one autochanger.
+ Date: 28 October 2005
+ Origin: Kern
+ Status:
- This is also a major scalability issue -- as the number of
- clients increases beyond several thousand, and the volume
- of data increases, transferring the data multiple times to
- produce additional copies of the backups will become
- physically impossible due to transfer speed
- issues. Generating multiple copies at server side will
- become the only practical option.
+ What: Currently, the autochanger script is locked based on
+ the autochanger. That is, if multiple drives are being
+ simultaneously used, the Storage daemon ensures that only
+ one drive at a time can access the mtx-changer script.
+ This change would base the locking on the control device,
+ rather than the autochanger. It would then permit two autochanger
+ definitions for the same autochanger, but with different
+ drives. Logically, the autochanger could then be "partitioned"
+ for different jobs, clients, or class of jobs, and if the locking
+ is based on the control device (e.g. /dev/sg0) the mtx-changer
+ script will be locked appropriately.
- How: I suspect that this will require adding a multiplexing
- SD that appears to be a SD to a specific FD, but 1-n FDs
- to the specific back end SDs managing the primary and copy
- pools. Storage pools will also need to acquire parameters
- to define the pools to be used for copies.
+ Why: This will permit users to partition autochangers for specific
+ use. It would also permit implementation of multiple Media
+ Types with no changes to the Storage daemon.
- Notes: I would commit some of my developers' time if we can agree
- on the design and behavior.
+Item 24: Automatic disabling of devices
+ Date: 2005-11-11
+ Origin: Peter Eriksson <peter at ifm.liu dot se>
+ Status:
+
+ What: After a configurable amount of fatal errors with a tape drive
+ Bacula should automatically disable further use of a certain
+ tape drive. There should also be "disable"/"enable" commands in
+ the "bconsole" tool.
+
+ Why: On a multi-drive jukebox there is a possibility of tape drives
+ going bad during large backups (needing a cleaning tape run,
+ tapes getting stuck). It would be advantageous if Bacula would
+ automatically disable further use of a problematic tape drive
+ after a configurable amount of errors has occurred.
+
+ An example: I have a multi-drive jukebox (6 drives, 380+ slots)
+ where tapes occasionally get stuck inside the drive. Bacula will
+ notice that the "mtx-changer" command will fail and then fail
+ any backup jobs trying to use that drive. However, it will still
+ keep on trying to run new jobs using that drive and fail -
+ forever, and thus failing lots and lots of jobs... Since we have
+ many drives Bacula could have just automatically disabled
+ further use of that drive and used one of the other ones
+ instead.
+
+Item 25: Implement huge exclude list support using hashing.
+ Date: 28 October 2005
+ Origin: Kern
+ Status:
+
+ What: Allow users to specify very large exclude list (currently
+ more than about 1000 files is too many).
+
+ Why: This would give the users the ability to exclude all
+ files that are loaded with the OS (e.g. using rpms
+ or debs). If the user can restore the base OS from
+ CDs, there is no need to backup all those files. A
+ complete restore would be to restore the base OS, then
+ do a Bacula restore. By excluding the base OS files, the
+ backup set will be *much* smaller.

+ What: An easy option to skip a certain job on a certain date.

+
+ What: The abilty to archive to media (dvd/cd) in a uncompressd format
+ for dead filing (archiving not backing up)
+
+ Why: At my works when jobs are finished and moved off of the main file
+ servers (raid based systems) onto a simple linux file server (ide based
+ system) so users can find old information without contacting the IT
+ dept.
+
+ So this data dosn't realy change it only gets added to,
+ But it also needs backing up. At the moment it takes
+ about 8 hours to back up our servers (working data) so
+ rather than add more time to existing backups i am trying
+ to implement a system where we backup the acrhive data to
+ cd/dvd these disks would only need to be appended to
+ (burn only new/changed files to new disks for off site
+ storage). basialy understand the differnce between
+ achive data and live data.
+
+ Notes: scan the data and email me when it needs burning divide
+ into predifind chunks keep a recored of what is on what
+ disk make me a label (simple php->mysql=>pdf stuff) i
+ could do this bit ability to save data uncompresed so
+ it can be read in any other system (future proof data)
+ save the catalog with the disk as some kind of menu

+ Item : Clustered file-daemons
+ Origin: Alan Brown ajb2 at mssl dot ucl dot ac dot uk
+ Date: 24 July 2006
+ Status:
+ What: A "virtual" filedaemon, which is actually a cluster of real ones.
+
+ Why: In the case of clustered filesystems (SAN setups, GFS, or OCFS2, etc)
+ multiple machines may have access to the same set of filesystems
+
+ For performance reasons, one may wish to initate backups from
+ several of these machines simultaneously, instead of just using
+ one backup source for the common clustered filesystem.
+
+ For obvious reasons, normally backups of $A-FD/$PATH and
+ B-FD/$PATH are treated as different backup sets. In this case
+ they are the same communal set.
+
+ Likewise when restoring, it would be easier to just specify
+ one of the cluster machines and let bacula decide which to use.
+
+ This can be faked to some extent using DNS round robin entries
+ and a virtual IP address, however it means "status client" will
+ always give bogus answers. Additionally there is no way of
+ spreading the load evenly among the servers.
+
+ What is required is something similar to the storage daemon
+ autochanger directives, so that Bacula can keep track of
+ operating backups/restores and direct new jobs to a "free"
+ client.

+ Origin: Russell Howe <russell_howe dot wreckage dot org>
+ Date: 26 July 2006
+ Status:
+
+ What: It would be nice for the database backend to support more
+ databases. I'm thinking of SQL Server at the moment, but I guess Oracle,
+ DB2, MaxDB, etc are all candidates. SQL Server would presumably be
+ implemented using FreeTDS or maybe an ODBC library?
+
+ Why: We only really have one database server, which is MS SQL Server
+ 2000. Maintaining a second one for the backup software (we grew out of
+ SQLite, which I liked, but which didn't work so well with our database
+ size). We don't really have a machine with the resources to run
+ postgres, and would rather only maintain a single DBMS. We're stuck with
+ SQL Server because pretty much all the company's custom applications
+ (written by consultants) are locked into SQL Server 2000. I can imagine
+ this scenario is fairly common, and it would be nice to use the existing
+ properly specced database server for storing Bacula's catalog, rather
+ than having to run a second DBMS.

+ Date: 27th July 2006
+ Status:
+
+ What: Split documentation in several books
+
+ Why: Bacula manual has now more than 600 pages, and looking for
+ implementation details is getting complicated. I think
+ it would be good to split the single volume in two or
+ maybe three parts:
+
+ 1) Introduction, requirements and tutorial, typically
+ are useful only until first installation time
+
+ 2) Basic installation and configuration, with all the
+ gory details about the directives supported 3)
+ Advanced Bacula: testing, troubleshooting, GUI and
+ ancillary programs, security managements, scripting,

+
+ What: When I do update -> Volume parameters -> All Volumes

+
+ Why: I have many pools and therefore unhappy with manually

+
+Item n: Automatic promotion of backup levels
+ Date: 19 January 2006
+ Origin: Adam Thornton <athornton@sinenomine.net>
+ Status: Blue sky
+
+ What: Amanda has a feature whereby it estimates the space that a
+ differential, incremental, and full backup would take. If the
+ difference in space required between the scheduled level and the next
+ level up is beneath some user-defined critical threshold, the backup
+ level is bumped to the next type. Doing this minimizes the number of
+ volumes necessary during a restore, with a fairly minimal cost in
+ backup media space.
+
+ Why: I know at least one (quite sophisticated and smart) user
+ for whom the absence of this feature is a deal-breaker in terms of
+ using Bacula; if we had it it would eliminate the one cool thing
+ Amanda can do and we can't (at least, the one cool thing I know of).

+Item n+1: Incorporation of XACML2/SAML2 parsing
+ Date: 19 January 2006
+ Origin: Adam Thornton <athornton@sinenomine.net>
+ Status: Blue sky
+
+ What: XACML is "eXtensible Access Control Markup Language" and
+ "SAML is the "Security Assertion Markup Language"--an XML standard
+ for making statements about identity and authorization. Having these
+ would give us a framework to approach ACLs in a generic manner, and
+ in a way flexible enough to support the four major sorts of ACLs I
+ see as a concern to Bacula at this point, as well as (probably) to
+ deal with new sorts of ACLs that may appear in the future.
+
+ Why: Bacula is beginning to need to back up systems with ACLs
+ that do not map cleanly onto traditional Unix permissions. I see
+ four sets of ACLs--in general, mutually incompatible with one
+ another--that we're going to need to deal with. These are: NTFS
+ ACLs, POSIX ACLs, NFSv4 ACLS, and AFS ACLS. (Some may question the
+ relevance of AFS; AFS is one of Sine Nomine's core consulting
+ businesses, and having a reputable file-level backup and restore
+ technology for it (as Tivoli is probably going to drop AFS support
+ soon since IBM no longer supports AFS) would be of huge benefit to
+ our customers; we'd most likely create the AFS support at Sine Nomine
+ for inclusion into the Bacula (and perhaps some changes to the
+ OpenAFS volserver) core code.)
+
+ Now, obviously, Bacula already handles NTFS just fine. However, I
+ think there's a lot of value in implementing a generic ACL model, so
+ that it's easy to support whatever particular instances of ACLs come
+ down the pike: POSIX ACLS (think SELinux) and NFSv4 are the obvious
+ things arriving in the Linux world in a big way in the near future.
+ XACML, although overcomplicated for our needs, provides this
+ framework, and we should be able to leverage other people's
+ implementations to minimize the amount of work *we* have to do to get
+ a generic ACL framework. Basically, the costs of implementation are
+ high, but they're largely both external to Bacula and already sunk.
+
+Item 1: Add an over-ride in the Schedule configuration to use a
+ different pool for different backup types.
+
+Date: 19 Jan 2005
+Origin: Chad Slater <chad.slater@clickfox.com>
+Status:
+
+ What: Adding a FullStorage=BigTapeLibrary in the Schedule resource
+ would help those of us who use different storage devices for different
+ backup levels cope with the "auto-upgrade" of a backup.
+
+ Why: Assume I add several new device to be backed up, i.e. several
+ hosts with 1TB RAID. To avoid tape switching hassles, incrementals are
+ stored in a disk set on a 2TB RAID. If you add these devices in the
+ middle of the month, the incrementals are upgraded to "full" backups,
+ but they try to use the same storage device as requested in the
+ incremental job, filling up the RAID holding the differentials. If we
+ could override the Storage parameter for full and/or differential
+ backups, then the Full job would use the proper Storage device, which
+ has more capacity (i.e. a 8TB tape library.
+
+
+Item: Implement multiple numeric backup levels as supported by dump
+Date: 3 April 2006
+Origin: Daniel Rich <drich@employees.org>
+Status:
+What: Dump allows specification of backup levels numerically instead of just
+ "full", "incr", and "diff". In this system, at any given level, all
+ files are backed up that were were modified since the last backup of a
+ higher level (with 0 being the highest and 9 being the lowest). A
+ level 0 is therefore equivalent to a full, level 9 an incremental, and
+ the levels 1 through 8 are varying levels of differentials. For
+ bacula's sake, these could be represented as "full", "incr", and
+ "diff1", "diff2", etc.
+
+Why: Support of multiple backup levels would provide for more advanced backup
+ rotation schemes such as "Towers of Hanoi". This would allow better
+ flexibility in performing backups, and can lead to shorter recover
+ times.
+
+Notes: Legato Networker supports a similar system with full, incr, and 1-9 as
+ levels.
+
+Kern notes: I think this would add very little functionality, but a *lot* of
+ additional overhead to Bacula.

+ Date: Tue Aug 22 17:13:39 EDT 2006
+ Status:
+
+ What: Change the name of the spool file to include the JobID
+
+ Why: JobIDs are the common key used to refer to jobs, yet the
+ spoolfile name doesn't include that information. The date/time
+ stamp is useful (and should be retained).
+
+
+
+Item 2: include timestamp of job launch in "stat clients" output
+ Origin: Mark Bergman <mark.bergman@uphs.upenn.edu>
+ Date: Tue Aug 22 17:13:39 EDT 2006
+ Status:
+
+ What: The "stat clients" command doesn't include any detail on when
+ the active backup jobs were launched.
+
+ Why: Including the timestamp would make it much easier to decide whether
+ a job is running properly.
+
+ Notes: It may be helpful to have the output from "stat clients" formatted
+ more like that from "stat dir" (and other commands), in a column
+ format. The per-client information that's currently shown (level,
+ client name, JobId, Volume, pool, device, Files, etc.) is good, but
+ somewhat hard to parse (both programmatically and visually),
+ particularly when there are many active clients.
+
+Item 1: Filesystemwatch triggered backup.
+ Date: 31 August 2006
+ Origin: Jesper Krogh <jesper@krogh.cc>
+ Status: Unimplemented, depends probably on "client initiated backups"
+
+ What: With inotify and similar filesystem triggeret notification
+ systems is it possible to have the file-daemon to monitor
+ filesystem changes and initiate backup.
+
+ Why: There are 2 situations where this is nice to have.
+ 1) It is possible to get a much finer-grained backup than
+ the fixed schedules used now.. A file created and deleted
+ a few hours later, can automatically be caught.
+
+ 2) The introduced load on the system will probably be
+ distributed more even on the system.
+
+ Notes: This can be combined with configration that specifies
+ something like: "at most every 15 minutes or when changes
+ consumed XX MB".
+
+Item n: Message mailing based on backup types
+Origin: Evan Kaufman <evan.kaufman@gmail.com>
+ Date: January 6, 2006
+Status:
+
+ What: In the "Messages" resource definitions, allowing messages
+ to be mailed based on the type (backup, restore, etc.) and level
+ (full, differential, etc) of job that created the originating
+ message(s).
+
+Why: It would, for example, allow someone's boss to be emailed
+ automatically only when a Full Backup job runs, so he can
+ retrieve the tapes for offsite storage, even if the IT dept.
+ doesn't (or can't) explicitly notify him. At the same time, his
+ mailbox wouldnt be filled by notifications of Verifies, Restores,
+ or Incremental/Differential Backups (which would likely be kept
+ onsite).
+
+Notes:
+ One way this could be done is through additional message types, for example:
+
+ Messages {
+ # email the boss only on full system backups
+ Mail = boss@mycompany.com = full, !incremental, !differential, !restore,
+ !verify, !admin
+ # email us only when something breaks
+ MailOnError = itdept@mycompany.com = all
+ }

+
+Item n: Allow inclusion/exclusion of files in a fileset by creation/mod times
+ Origin: Evan Kaufman <evan.kaufman@gmail.com>
+ Date: January 11, 2006
+ Status:
+
+ What: In the vein of the Wild and Regex directives in a Fileset's
+ Options, it would be helpful to allow a user to include or exclude
+ files and directories by creation or modification times.
+
+ You could factor the Exclude=yes|no option in much the same way it
+ affects the Wild and Regex directives. For example, you could exclude
+ all files modified before a certain date:
+
+ Options {
+ Exclude = yes
+ Modified Before = ####
+ }
+
+ Or you could exclude all files created/modified since a certain date:
+
+ Options {
+ Exclude = yes
+ Created Modified Since = ####
+ }
+
+ The format of the time/date could be done several ways, say the number
+ of seconds since the epoch:
+ 1137008553 = Jan 11 2006, 1:42:33PM # result of `date +%s`
+
+ Or a human readable date in a cryptic form:
+ 20060111134233 = Jan 11 2006, 1:42:33PM # YYYYMMDDhhmmss
+
+ Why: I imagine a feature like this could have many uses. It would
+ allow a user to do a full backup while excluding the base operating
+ system files, so if I installed a Linux snapshot from a CD yesterday,
+ I'll *exclude* all files modified *before* today. If I need to
+ recover the system, I use the CD I already have, plus the tape backup.
+ Or if, say, a Windows client is hit by a particularly corrosive
+ virus, and I need to *exclude* any files created/modified *since* the
+ time of infection.
+
+ Notes: Of course, this feature would work in concert with other
+ in/exclude rules, and wouldnt override them (or each other).
+
+ Notes: The directives I'd imagine would be along the lines of
+ "[Created] [Modified] [Before|Since] = <date>".
+ So one could compare against 'ctime' and/or 'mtime', but ONLY 'before'
+ or 'since'.

+
+ What: be able to send a email message for a specified email address if (and only if) a job finishes successfully.
+ Its similar to the MailOnError feature.
+
+ Why: The importance is about the same as MailOnError feature.
+ Since its not possible to do it using bacula's message types(info, error,...)filter, this could be done using some kind of filter, right after the mail was sent.
+ But since there is a MailOnError feature, why not have a MailOnSuccess feature?

+ Imagine I want bacula to send ONLY successful job reports/messages to baculaOK@domain.
+ When a job starts, bacula send the message : 10-Nov 17:37 bserver-dir: Start Backup JobId 1605, Job=Job.GSI04.2006-11-10_17.37.30
+ Since this is a info message (msgtype = M_INFO) the "bacula's messaging system" put it on the job messages (jcr->jcr_msgs) to be sent
+ to all dest that have the info type enabled (including baculaOK@domain).
+ But when/if the job fails, that message (10-Nov 17:37 bserver-dir: Start Backup JobId 1605, Job=Job.GSI04.2006-11-10_17.37.30) has already
+ been queued to be sent to baculaOK@domain, even though it refers to a unsuccessful backup.
+ So when its time to send all messages to emails, the "bacula's messaging system" send that message (10-Nov 17:37 bserver-dir: Start
+ Backup JobId 1605, Job=Job.GSI04.2006-11-10_17.37.30) to baculaOK@domain, but using the subject "bacula ERROR", because the job terminated unsuccessful.
+
+ This "problem" could also happen if I wanted bacula to send emails regarding unsuccessful backups, if i didnt use the MailOnError feature.
+ This feature is implemented so that if messages that where queued to be sent if the backup was unsuccessful, to be discarded if the backup is
