+Item 42: Relabel disk volume after recycling
Item 1: Ability to restart failed jobs
Notes: Requires Accurate to restart correctly. Must completed have a minimum
volume of data or files stored on Volume before enabling.
+Item 2: SD redesign
+ Date: 8 August 2010
+ Origin: Kern
+ Status:
+
+ What: Various ideas for redesigns planned for the SD:
+ 1. One thread per drive
+ 2. Design a class structure for all objects in the SD.
+ 3. Make Device into C++ classes for each device type
+ 4. Make Device have a proxy (front end intercept class) that will permit control over locking and changing the real device pointer. It can also permit delaying opening, so that we can adapt to having another program that tells us the Archive device name.
+ 5. Allow plugins to create new on the fly devices
+ 6. Separate SD volume manager
+ 7. Volume manager tells Bacula what drive or device to use for a given volume
+
+ Why: It will simplify the SD, make it more modular, reduce locking
+ conflicts, and allow multiple buffer backups.
+
+Item 3: NDMP backup
+ Date: 8 August 2010
+ Origin: Bacula Systems
+ Status: Enterprise only if implemented by Bacula Systems
+
+ What: Backup/restore via NDMP -- most important NetApp compatibility
+
+Item 4: SAP backup
+ Date: 8 August 2010
+ Origin: Bacula Systems
+ Status: Enterprise only if implemented by Bacula Systems
+
+ What: Backup/restore SAP databases (MaxDB, Oracle, possibly DB2)
+
+Item 5: Oracle backup
+ Date: 8 August 2010
+ Origin: Bacula Systems
+ Status: Enterprise only if implemented by Bacula Systems
+
+ What: Backup/restore Oracle databases
+
+Item 6: 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 7: Include all conf files in specified directory
+Date: 18 October 2008
+Origin: Database, Lda. Maputo, Mozambique
+Contact:Cameron Smith / cameron.ord@database.co.mz
+Status: New request
+
+What: A directive something like "IncludeConf = /etc/bacula/subconfs" Every
+ time Bacula Director restarts or reloads, it will walk the given
+ directory (non-recursively) and include the contents of any files
+ therein, as though they were appended to bacula-dir.conf
+
+Why: Permits simplified and safer configuration for larger installations with
+ many client PCs. Currently, through judicious use of JobDefs and
+ similar directives, it is possible to reduce the client-specific part of
+ a configuration to a minimum. The client-specific directives can be
+ prepared according to a standard template and dropped into a known
+ directory. However it is still necessary to add a line to the "master"
+ (bacula-dir.conf) referencing each new file. This exposes the master to
+ unnecessary risk of accidental mistakes and makes automation of adding
+ new client-confs, more difficult (it is easier to automate dropping a
+ file into a dir, than rewriting an existing file). Ken has previously
+ made a convincing argument for NOT including Bacula's core configuration
+ in an RDBMS, but I believe that the present request is a reasonable
+ extension to the current "flat-file-based" configuration philosophy.
+
+Notes: There is NO need for any special syntax to these files. They should
+ contain standard directives which are simply "inlined" to the parent
+ file as already happens when you explicitly reference an external file.
+
+Notes: (kes) this can already be done with scripting
+ From: John Jorgensen <jorgnsn@lcd.uregina.ca>
+ The bacula-dir.conf at our site contains these lines:
+
+ #
+ # Include subfiles associated with configuration of clients.
+ # They define the bulk of the Clients, Jobs, and FileSets.
+ #
+ @|"sh -c 'for f in /etc/bacula/clientdefs/*.conf ; do echo @${f} ; done'"
+
+ and when we get a new client, we just put its configuration into
+ a new file called something like:
+
+ /etc/bacula/clientdefs/clientname.conf
+
+
+
+
+Item 8: Reduction of communications bandwidth for a backup
+ Date: 14 October 2008
+ Origin: Robin O'Leary (Equiinet)
+ Status:
+
+ What: Using rdiff techniques, Bacula could significantly reduce
+ the network data transfer volume to do a backup.
+
+ Why: Faster backup across the Internet
+
+ Notes: This requires retaining certain data on the client during a Full
+ backup that will speed up subsequent backups.
+
+
+Item 9: Concurrent spooling and despooling within a single job.
+Date: 17 nov 2009
+Origin: Jesper Krogh <jesper@krogh.cc>
+Status: NEW
+What: When a job has spooling enabled and the spool area size is
+ less than the total volumes size the storage daemon will:
+ 1) Spool to spool-area
+ 2) Despool to tape
+ 3) Go to 1 if more data to be backed up.
+
+ Typical disks will serve data with a speed of 100MB/s when
+ dealing with large files, network it typical capable of doing 115MB/s
+ (GbitE). Tape drives will despool with 50-90MB/s (LTO3) 70-120MB/s
+ (LTO4) depending on compression and data.
+
+ As bacula currently works it'll hold back data from the client until
+ de-spooling is done, now matter if the spool area can handle another
+ block of data. Say given a FileSet of 4TB and a spool-area of 100GB and
+ a Maximum Job Spool Size set to 50GB then above sequence could be
+ changed to allow to spool to the other 50GB while despooling the first
+ 50GB and not holding back the client while doing it. As above numbers
+ show, depending on tape-drive and disk-arrays this potentially leads to
+ a cut of the backup-time of 50% for the individual jobs.
+
+ Real-world example, backing up 112.6GB (large files) to LTO4 tapes
+ (despools with ~75MB/s, data is gzipped on the remote filesystem.
+ Maximum Job Spool Size = 8GB
+
+ Current:
+ Size: 112.6GB
+ Elapsed time (total time): 46m 15s => 2775s
+ Despooling time: 25m 41s => 1541s (55%)
+ Spooling time: 20m 34s => 1234s (45%)
+ Reported speed: 40.58MB/s
+ Spooling speed: 112.6GB/1234s => 91.25MB/s
+ Despooling speed: 112.6GB/1541s => 73.07MB/s
+
+ So disk + net can "keep up" with the LTO4 drive (in this test)
+
+ Prosed change would effectively make the backup run in the "despooling
+ time" 1541s giving a reduction to 55% of the total run time.
+
+ In the situation where the individual job cannot keep up with LTO-drive
+ spooling enables efficient multiplexing of multiple concurrent jobs onto
+ the same drive.
+
+Why: When dealing with larger volumes the general utillization of the
+ network/disk is important to maximize in order to be able to run a full
+ backup over a weekend. Current work-around is to split the FileSet in
+ smaller FileSet and Jobs but that leads to more configuration mangement
+ and is harder to review for completeness. Subsequently it makes restores
+ more complex.
+
+
+
+Item 10: Start spooling even when waiting on tape
+ Origin: Tobias Barth <tobias.barth@web-arts.com>
+ Date: 25 April 2008
+ Status:
+
+ What: If a job can be spooled to disk before writing it to tape, it should
+ be spooled immediately. Currently, bacula waits until the correct
+ tape is inserted into the drive.
+
+ Why: It could save hours. When bacula waits on the operator who must insert
+ the correct tape (e.g. a new tape or a tape from another media
+ pool), bacula could already prepare the spooled data in the spooling
+ directory and immediately start despooling when the tape was
+ inserted by the operator.
+
+ 2nd step: Use 2 or more spooling directories. When one directory is
+ currently despooling, the next (on different disk drives) could
+ already be spooling the next data.
+
+ Notes: I am using bacula 2.2.8, which has none of those features
+ implemented.
+
+
+Item 11: Add ability to Verify any specified Job.
+Date: 17 January 2008
+Origin: portrix.net Hamburg, Germany.
+Contact: Christian Sabelmann
+Status: 70% of the required Code is part of the Verify function since v. 2.x
+
+ What:
+ The ability to tell Bacula which Job should verify instead of
+ automatically verify just the last one.
+
+ Why:
+ It is sad that such a powerfull feature like Verify Jobs
+ (VolumeToCatalog) is restricted to be used only with the last backup Job
+ of a client. Actual users who have to do daily Backups are forced to
+ also do daily Verify Jobs in order to take advantage of this useful
+ feature. This Daily Verify after Backup conduct is not always desired
+ and Verify Jobs have to be sometimes scheduled. (Not necessarily
+ scheduled in Bacula). With this feature Admins can verify Jobs once a
+ Week or less per month, selecting the Jobs they want to verify. This
+ feature is also not to difficult to implement taking in account older bug
+ reports about this feature and the selection of the Job to be verified.
+
+ Notes: For the verify Job, the user could select the Job to be verified
+ from a List of the latest Jobs of a client. It would also be possible to
+ verify a certain volume. All of these would naturaly apply only for
+ Jobs whose file information are still in the catalog.
+
+
+Item 12: Data encryption on storage daemon
+ Origin: Tobias Barth <tobias.barth at web-arts.com>
+ Date: 04 February 2009
+ Status: new
+
+ What: The storage demon should be able to do the data encryption that can
+ currently be done by the file daemon.
+
+ Why: This would have 2 advantages:
+ 1) one could encrypt the data of unencrypted tapes by doing a
+ migration job
+ 2) the storage daemon would be the only machine that would have
+ to keep the encryption keys.
+
+ Notes from Landon:
+ As an addendum to the feature request, here are some crypto
+ implementation details I wrote up regarding SD-encryption back in Jan
+ 2008:

+Item 13: Possibilty to schedule Jobs on last Friday of the month
+Origin: Carsten Menke <bootsy52 at gmx dot net>
+Date: 02 March 2008
+Status:
+
+ What: Currently if you want to run your monthly Backups on the last
+ Friday of each month this is only possible with workarounds (e.g
+ scripting) (As some months got 4 Fridays and some got 5 Fridays)
+ The same is true if you plan to run your yearly Backups on the
+ last Friday of the year. It would be nice to have the ability to
+ use the builtin scheduler for this.
+
+ Why: In many companies the last working day of the week is Friday (or
+ Saturday), so to get the most data of the month onto the monthly
+ tape, the employees are advised to insert the tape for the
+ monthly backups on the last friday of the month.
+
+ Notes: To give this a complete functionality it would be nice if the
+ "first" and "last" Keywords could be implemented in the
+ scheduler, so it is also possible to run monthy backups at the
+ first friday of the month and many things more. So if the syntax
+ would expand to this {first|last} {Month|Week|Day|Mo-Fri} of the
+ {Year|Month|Week} you would be able to run really flexible jobs.
+
+ To got a certain Job run on the last Friday of the Month for example
+ one could then write
+
+ Run = pool=Monthly last Fri of the Month at 23:50
-Item 2: Scheduling syntax that permits more flexibility and options
+ ## Yearly Backup
+
+ Run = pool=Yearly last Fri of the Year at 23:50
+
+ ## Certain Jobs the last Week of a Month
+
+ Run = pool=LastWeek last Week of the Month at 23:50
+
+ ## Monthly Backup on the last day of the month
+
+ Run = pool=Monthly last Day of the Month at 23:50

-Item 5: 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>
- Status:
-
- What: Make Bacula manage tape life cycle information, tape reuse
- times and drive cleaning cycles.
-
- Why: All three parts of this project are important when operating
- backups.
- We need to know which tapes need replacement, and we need to
- make sure the drives are cleaned when necessary. While many
- tape libraries and even autoloaders can handle all this
- automatically, support by Bacula can be helpful for smaller
- (older) libraries and single drives. Limiting the number of
- times a tape is used might prevent tape errors when using
- tapes until the drives can't read it any more. Also, checking
- drive status during operation can prevent some failures (as I
- [Arno] had to learn the hard way...)
-
- Notes: First, Bacula could (and even does, to some limited extent)
- record tape and drive usage. For tapes, the number of mounts,
- the amount of data, and the time the tape has actually been
- running could be recorded. Data fields for Read and Write
- time and Number of mounts already exist in the catalog (I'm
- not sure if VolBytes is the sum of all bytes ever written to
- that volume by Bacula). This information can be important
- when determining which media to replace. The ability to mark
- Volumes as "used up" after a given number of write cycles
- should also be implemented so that a tape is never actually
- worn out. For the tape drives known to Bacula, similar
- information is interesting to determine the device status and
- expected life time: Time it's been Reading and Writing, number
- of tape Loads / Unloads / Errors. This information is not yet
- recorded as far as I [Arno] know. A new volume status would
- be necessary for the new state, like "Used up" or "Worn out".
- Volumes with this state could be used for restores, but not
- for writing. These volumes should be migrated first (assuming
- migration is implemented) and, once they are no longer needed,
- could be moved to a Trash pool.
-
- The next step would be to implement a drive cleaning setup.
- Bacula already has knowledge about cleaning tapes. Once it
- has some information about cleaning cycles (measured in drive
- run time, number of tapes used, or calender days, for example)
- it can automatically execute tape cleaning (with an
- autochanger, obviously) or ask for operator assistance loading
- a cleaning tape.
-
- The final step would be to implement TAPEALERT checks not only
- when changing tapes and only sending the information to the
- administrator, but rather checking after each tape error,
- checking on a regular basis (for example after each tape
- file), and also before unloading and after loading a new tape.
- Then, depending on the drives TAPEALERT state and the known
- drive cleaning state Bacula could automatically schedule later
- cleaning, clean immediately, or inform the operator.
-
- Implementing this would perhaps require another catalog change
- and perhaps major changes in SD code and the DIR-SD protocol,
- so I'd only consider this worth implementing if it would
- actually be used or even needed by many people.
-
- Implementation of these projects could happen in three distinct
- sub-projects: Measuring Tape and Drive usage, retiring
- volumes, and handling drive cleaning and TAPEALERTs.

-Item 6: Allow FD to initiate a backup
-Origin: Frank Volf (frank at deze dot org)
-Date: 17 November 2005
-Status:
-
-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: Makes backup of laptops much easier.
-Notes: - The FD already has code for the monitor interface
- - It could be nice to have a .job command that lists authorized
- jobs.
- - Commands need to be restricted on the Director side
- (for example by re-using the runscript flag)
- - The Client resource can be used to authorize the connection
- - In a first time, the client can't modify job parameters
- - We need a way to run a status command to follow job progression
-
- This project consists of the following points
- 1. Modify the FD to have a "mini-console" interface that
- permits it to connect to the Director and start a
- backup job of itself.
- 2. The list of jobs that can be started by the FD are
- defined in the Director (possibly via a restricted
- console).
- 3. Modify the existing tray monitor code in the Win32 FD
- so that it is a separate program from the FD.
- 4. The tray monitor program should be extended to permit
- initiating a backup.
- 5. No new Director directives should be added without
- prior consultation with the Bacula developers.
- 6. The comm line used by the FD to connect to the Director
- should be re-used by the Director to do the backup.
- This feature is partially implemented in the Director.
- 7. The FD may have a new directive that allows it to start
- a backup when the FD starts.
- 8. The console interface to the FD should be extended to
- permit a properly authorized console to initiate a
- backup via the FD.

-Item 7: Implement Storage daemon compression
- Date: 18 December 2006
- Origin: Vadim A. Umanski , e-mail umanski@ext.ru
- Status:
- What: The ability to compress backup data on the SD receiving data
- instead of doing that on client sending data.
- Why: The need is practical. I've got some machines that can send
- data to the network 4 or 5 times faster than compressing
- them (I've measured that). They're using fast enough SCSI/FC
- disk subsystems but rather slow CPUs (ex. UltraSPARC II).
- And the backup server has got a quite fast CPUs (ex. Dual P4
- Xeons) and quite a low load. When you have 20, 50 or 100 GB
- of raw data - running a job 4 to 5 times faster - that
- really matters. On the other hand, the data can be
- compressed 50% or better - so losing twice more space for
- disk backup is not good at all. And the network is all mine
- (I have a dedicated management/provisioning network) and I
- can get as high bandwidth as I need - 100Mbps, 1000Mbps...
- That's why the server-side compression feature is needed!

-Item 9: Ability to reconnect a disconnected comm line
- Date: 26 April 2009
- Origin: Kern/Eric
- Status:
-
- What: Often jobs fail because of a communications line drop. In that
- case, Bacula should be able to reconnect to the other daemon and
- resume the job.
-
- Why: Avoids backuping data already saved.
-
- Notes: *Very* complicated from a design point of view because of authenication.

- similar directives, it is possible to reduce the client-specific part of
- a configuration to a minimum. The client-specific directives can be
- prepared according to a standard template and dropped into a known
- directory. However it is still necessary to add a line to the "master"
- (bacula-dir.conf) referencing each new file. This exposes the master to
- unnecessary risk of accidental mistakes and makes automation of adding
- new client-confs, more difficult (it is easier to automate dropping a
- file into a dir, than rewriting an existing file). Ken has previously
- made a convincing argument for NOT including Bacula's core configuration
- in an RDBMS, but I believe that the present request is a reasonable
- extension to the current "flat-file-based" configuration philosophy.
-
-Notes: There is NO need for any special syntax to these files. They should
- contain standard directives which are simply "inlined" to the parent
- file as already happens when you explicitly reference an external file.
-
-Notes: (kes) this can already be done with scripting
- From: John Jorgensen <jorgnsn@lcd.uregina.ca>
- The bacula-dir.conf at our site contains these lines:
-
- #
- # Include subfiles associated with configuration of clients.
- # They define the bulk of the Clients, Jobs, and FileSets.
- #
- @|"sh -c 'for f in /etc/bacula/clientdefs/*.conf ; do echo @${f} ; done'"
-
- and when we get a new client, we just put its configuration into
- a new file called something like:
-
- /etc/bacula/clientdefs/clientname.conf

-Item 12: Multiple threads in file daemon for the same job
- Date: 27 November 2005
- Origin: Ove Risberg (Ove.Risberg at octocode dot com)
- Status:
-
- What: I want the file daemon to start multiple threads for a backup
- job so the fastest possible backup can be made.
-
- The file daemon could parse the FileSet information and start
- one thread for each File entry located on a separate
- filesystem.
-
- A confiuration option in the job section should be used to
- enable or disable this feature. The confgutration option could
- specify the maximum number of threads in the file daemon.
-
- If the theads could spool the data to separate spool files
- the restore process will not be much slower.
-
- Why: Multiple concurrent backups of a large fileserver with many
- disks and controllers will be much faster.
-
- Notes: (KES) This is not necessary and could be accomplished
- by having two jobs. In addition, the current VSS code
- is single thread.

-Item 13: Possibilty to schedule Jobs on last Friday of the month
-Origin: Carsten Menke <bootsy52 at gmx dot net>
-Date: 02 March 2008
-Status:
-
- What: Currently if you want to run your monthly Backups on the last
- Friday of each month this is only possible with workarounds (e.g
- scripting) (As some months got 4 Fridays and some got 5 Fridays)
- The same is true if you plan to run your yearly Backups on the
- last Friday of the year. It would be nice to have the ability to
- use the builtin scheduler for this.
-
- Why: In many companies the last working day of the week is Friday (or
- Saturday), so to get the most data of the month onto the monthly
- tape, the employees are advised to insert the tape for the
- monthly backups on the last friday of the month.
-
- Notes: To give this a complete functionality it would be nice if the
- "first" and "last" Keywords could be implemented in the
- scheduler, so it is also possible to run monthy backups at the
- first friday of the month and many things more. So if the syntax
- would expand to this {first|last} {Month|Week|Day|Mo-Fri} of the
- {Year|Month|Week} you would be able to run really flexible jobs.
-
- To got a certain Job run on the last Friday of the Month for example
- one could then write
-
- Run = pool=Monthly last Fri of the Month at 23:50
+ Repeat = 3w
+ }
+ }
+ }

- What: The "stat clients" command doesn't include any detail on when

+ What: SD has a "Maximum Volume Size" statement, which is deprecated and
+ superseded by the Pool resource statement "Maximum Volume Bytes".
+ It would be good if either statement could be used in Storage

- Why: Including the timestamp would make it much easier to decide whether
- a job is running properly.
+ Why: Pools do not have to be restricted to a single storage type/device;
+ thus, it may be impossible to define Maximum Volume Bytes in the
+ Pool resource. The old MaxVolSize statement is deprecated, as it
+ is SD side only. I am using the same pool for different devices.
- 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.
+ Notes: State of idea currently unknown. Storage resources in the dir

+ Date: 05 August 2008
+ Status:
+
+ What: Make it possible to backup and restore Encypted Files from and to
+ Windows systems without the need to decrypt it by using the raw
+ encryption functions API (see:
+ http://msdn2.microsoft.com/en-us/library/aa363783.aspx)
+ that is provided for that reason by Microsoft.
+ If a file ist encrypted could be examined by evaluating the
+ FILE_ATTRIBUTE_ENCRYTED flag of the GetFileAttributes
+ function.
+ For each file backed up or restored by FD on Windows, check if
+ the file is encrypted; if so then use OpenEncryptedFileRaw,
+ ReadEncryptedFileRaw, WriteEncryptedFileRaw,
+ CloseEncryptedFileRaw instead of BackupRead and BackupWrite
+ API calls.
+
+ Why: Without the usage of this interface the fd-daemon running
+ under the system account can't read encypted Files because
+ the key needed for the decrytion is missed by them. As a result
+ actually encrypted files are not backed up
+ by bacula and also no error is shown while missing these files.
+
+ Notes: Using xxxEncryptedFileRaw API would allow to backup and
+ restore EFS-encrypted files without decrypting their data.
+ Note that such files cannot be restored "portably" (at least,
+ easily) but they would be restoreable to a different (or
+ reinstalled) Win32 machine; the restore would require setup
+ of a EFS recovery agent in advance, of course, and this shall

+ shall be clearly reported as errors.
+ See MSDN on the "Backup and Restore of Encrypted Files" topic:
+ http://msdn.microsoft.com/en-us/library/aa363783.aspx
+ Maybe the EFS support requires a new flag in the database for

+ Unfortunately, the implementation is not as straightforward as

+
+Why: Sometimes we have more then one system which requires backup

+Item 19. Allow FD to initiate a backup
+Origin: Frank Volf (frank at deze dot org)
+Date: 17 November 2005
+Status:
+
+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: Makes backup of laptops much easier.
+Notes: - The FD already has code for the monitor interface
+ - It could be nice to have a .job command that lists authorized
+ jobs.
+ - Commands need to be restricted on the Director side
+ (for example by re-using the runscript flag)
+ - The Client resource can be used to authorize the connection
+ - In a first time, the client can't modify job parameters
+ - We need a way to run a status command to follow job progression
+
+ This project consists of the following points
+ 1. Modify the FD to have a "mini-console" interface that
+ permits it to connect to the Director and start a
+ backup job of itself.
+ 2. The list of jobs that can be started by the FD are
+ defined in the Director (possibly via a restricted
+ console).
+ 3. Modify the existing tray monitor code in the Win32 FD
+ so that it is a separate program from the FD.
+ 4. The tray monitor program should be extended to permit
+ initiating a backup.
+ 5. No new Director directives should be added without
+ prior consultation with the Bacula developers.
+ 6. The comm line used by the FD to connect to the Director
+ should be re-used by the Director to do the backup.
+ This feature is partially implemented in the Director.
+ 7. The FD may have a new directive that allows it to start
+ a backup when the FD starts.
+ 8. The console interface to the FD should be extended to
+ permit a properly authorized console to initiate a
+ backup via the FD.

+ Origin: Vadim A. Umanski , e-mail umanski@ext.ru
+ Status:
+ What: The ability to compress backup data on the SD receiving data
+ instead of doing that on client sending data.
+ Why: The need is practical. I've got some machines that can send
+ data to the network 4 or 5 times faster than compressing
+ them (I've measured that). They're using fast enough SCSI/FC
+ disk subsystems but rather slow CPUs (ex. UltraSPARC II).
+ And the backup server has got a quite fast CPUs (ex. Dual P4
+ Xeons) and quite a low load. When you have 20, 50 or 100 GB
+ of raw data - running a job 4 to 5 times faster - that
+ really matters. On the other hand, the data can be
+ compressed 50% or better - so losing twice more space for
+ disk backup is not good at all. And the network is all mine
+ (I have a dedicated management/provisioning network) and I
+ can get as high bandwidth as I need - 100Mbps, 1000Mbps...
+ That's why the server-side compression feature is needed!

- per disk volume, and you use a custom Label format, for example:
- Label Format =
- "${Client}-${Level}-${NumVols:p/4/0/r}-${Year}_${Month}_${Day}-${Hour}_${Minute}"
- Why: Disk volumes in Bacula get the label/filename when they are used for the
- first time. If you use recycling and custom label format like above,
- the disk volume name doesn't match the contents after it has been
- recycled. This feature makes it possible to keep the label/filename
- in sync with the content and thus makes it easy to check/monitor the

-Origin: Jesper Krogh <jesper@krogh.cc>
-Status: NEW
-What: When a job has spooling enabled and the spool area size is
- less than the total volumes size the storage daemon will:
- 1) Spool to spool-area
- 2) Despool to tape
- 3) Go to 1 if more data to be backed up.
-
- Typical disks will serve data with a speed of 100MB/s when
- dealing with large files, network it typical capable of doing 115MB/s
- (GbitE). Tape drives will despool with 50-90MB/s (LTO3) 70-120MB/s
- (LTO4) depending on compression and data.
-
- As bacula currently works it'll hold back data from the client until
- de-spooling is done, now matter if the spool area can handle another
- block of data. Say given a FileSet of 4TB and a spool-area of 100GB and
- a Maximum Job Spool Size set to 50GB then above sequence could be
- changed to allow to spool to the other 50GB while despooling the first
- 50GB and not holding back the client while doing it. As above numbers
- show, depending on tape-drive and disk-arrays this potentially leads to
- a cut of the backup-time of 50% for the individual jobs.
-
- Real-world example, backing up 112.6GB (large files) to LTO4 tapes
- (despools with ~75MB/s, data is gzipped on the remote filesystem.
- Maximum Job Spool Size = 8GB

- Spooling speed: 112.6GB/1234s => 91.25MB/s
- Despooling speed: 112.6GB/1541s => 73.07MB/s
-
- So disk + net can "keep up" with the LTO4 drive (in this test)
-
- Prosed change would effectively make the backup run in the "despooling
- time" 1541s giving a reduction to 55% of the total run time.
-
- In the situation where the individual job cannot keep up with LTO-drive
- spooling enables efficient multiplexing of multiple concurrent jobs onto
- the same drive.
-Why: When dealing with larger volumes the general utillization of the
- network/disk is important to maximize in order to be able to run a full
- backup over a weekend. Current work-around is to split the FileSet in
- smaller FileSet and Jobs but that leads to more configuration mangement
- and is harder to review for completeness. Subsequently it makes restores
- more complex.

Status: Proposal

+Item 39: Implement a Storage device like Amazon's S3.
+ Date: 25 August 2008
+ Origin: Soren Hansen <soren@ubuntu.com>
+ Status: Not started.
+ What: Enable the storage daemon to store backup data on Amazon's
+ S3 service.
+
+ Why: Amazon's S3 is a cheap way to store data off-site.
+
+ Notes: If we configure the Pool to put only one job per volume (they don't
+ support append operation), and the volume size isn't to big (100MB?),
+ it should be easy to adapt the disk-changer script to add get/put
+ procedure with curl. So, the data would be safetly copied during the
+ Job.
+
+ Cloud should be only used with Copy jobs, users should always have
+ a copy of their data on their site.
+
+ We should also think to have our own cache, trying always to have
+ cloud volume on the local disk. (I don't know if users want to store
+ 100GB on cloud, so it shouldn't be a disk size problem). For example,
+ if bacula want to recycle a volume, it will start by downloading the
+ file to truncate it few seconds later, if we can avoid that...

+Item 40: Convert tray monitor on Windows to a stand alone program
+ Date: 26 April 2009
+ Origin: Kern/Eric
+ Status:
+
+ What: Separate Win32 tray monitor to be a separate program.
+
+ Why: Vista does not allow SYSTEM services to interact with the
+ desktop, so the current tray monitor does not work on Vista
+ machines.
+
+ Notes: Requires communicating with the FD via the network (simulate
+ a console connection).
+
+Item 41: 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>
+ Status:
+
+ What:
+ 1. Measure tape and drive usage (mostly implemented)
+ 2. Retiring a volume when too old or too many errors
+ 3. Handle cleaning and tape alerts.
+
+ Why: Needed
+
+
+Item 42: Relabel disk volume after recycling
+ Origin: Pasi Kärkkäinen <pasik@iki.fi>
+ Date: 07 May 2009.
+ Status: Not implemented yet, no code written.
+
+ What: The ability to relabel the disk volume (and thus rename the file on the
+ disk) after it has been recycled. Useful when you have a single job
+ per disk volume, and you use a custom Label format, for example:
+ Label Format =
+ "${Client}-${Level}-${NumVols:p/4/0/r}-${Year}_${Month}_${Day}-${Hour}_${Minute}"
+
+ Why: Disk volumes in Bacula get the label/filename when they are used for the
+ first time. If you use recycling and custom label format like above,
+ the disk volume name doesn't match the contents after it has been
+ recycled. This feature makes it possible to keep the label/filename
+ in sync with the content and thus makes it easy to check/monitor the
+ backups from the shell and/or normal file management tools, because
+ the filenames of the disk volumes match the content.
+
+ Notes: The configuration option could be "Relabel after Recycling = Yes".
