-
-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.

+
+Item 1: Ability to restart failed jobs
Date: 26 April 2009
Origin: Kern/Eric
Status:
Notes: Requires Accurate to restart correctly. Must completed have a minimum
volume of data or files stored on Volume before enabling.
-Item 3: Port bat to Win32
- Date: 26 April 2009
- Origin: Kern/Eric
- Status:
-
- What: Make bat run on Win32/64.
-
- Why: To have GUI on Windows
-
- Notes:
-
-Item 4: Convert Bacula existing 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 5: Ability to import/export Bacula database entities
- Date: 26 April 2009
- Origin: Eric
- Status:
-
- What: Create a Bacula ASCII SQL database independent format that permits
- importing and exporting database catalog Job entities.
-
- Why: For achival, database clustering, tranfer to other databases
- of any SQL engine.
-
- Notes: Job selection should be by Job, time, Volume, Client, Pool and possibly
- other criteria.
-
-
-Item 6: Ability to defer Batch Insert to a later time
- Date: 26 April 2009
- Origin: Eric
- Status:
-
- What: Instead of doing a Job Batch Insert at the end of the Job
- which might create resource contention with lots of Job,
- defer the insert to a later time.
-
- Why: Permits to focus on getting the data on the Volume and
- putting the metadata into the Catalog outside the backup
- window.
-
- Notes: Will use the proposed Bacula ASCII database import/export
- format (i.e. dependent on the import/export entities project).
-
-
-Item 7: List InChanger flag when doing restore.
- Origin: Jesper Krogh<jesper@krogh.cc>
- Date: 17 Oct 2008
- Status:
-
- What: When doing a restore the restore selection dialog ends by telling stuff
- like this:
- The job will require the following
- Volume(s) Storage(s) SD Device(s)
- ===========================================================================
- 000741L3 LTO-4 LTO3
- 000866L3 LTO-4 LTO3
- 000765L3 LTO-4 LTO3
- 000764L3 LTO-4 LTO3
- 000756L3 LTO-4 LTO3
- 001759L3 LTO-4 LTO3
- 001763L3 LTO-4 LTO3
- 001762L3 LTO-4 LTO3
- 001767L3 LTO-4 LTO3
-
- When having an autochanger, it would be really nice with an inChanger
- column so the operator knew if this restore job would stop waiting for
- operator intervention. This is done just by selecting the inChanger flag
- from the catalog and printing it in a seperate column.
-
- Why: This would help getting large restores through minimizing the
- time spent waiting for operator to drop by and change tapes in the library.
-
- Notes: [Kern] I think it would also be good to have the Slot as well,
- or some indication that Bacula thinks the volume is in the autochanger
- because it depends on both the InChanger flag and the Slot being
- valid.
-
-
-Item 8: Deletion of disk Volumes when pruned
- Date: Nov 25, 2005
- Origin: Ross Boylan <RossBoylan at stanfordalumni dot org> (edited
- by Kern)
- Status:
-
- 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 allow users more control over their Volumes and
- prevent disk based volumes from consuming too much space.
-
- Notes: The following two directives might do the trick:
-
- Volume Data Retention = <time period>
- Remove Volume After = <time period>
-
- The migration project should also remove a Volume that is
- migrated. This might also work for tape Volumes.
-
- Notes: (Kern). The data fields to control this have been added
- to the new 3.0.0 database table structure.
-
-
-
-Item 9: Implement Base jobs
- Date: 28 October 2005
- Origin: Kern
- Status:
-
- What: A base job is sort of like a Full save except that you
- will want the FileSet to contain only files that are
- unlikely to change in the future (i.e. a snapshot of
- most of your system after installing it). After the
- base job has been run, when you are doing a Full save,
- you specify one or more Base jobs to be used. All
- files that have been backed up in the Base job/jobs but
- not modified will then be excluded from the backup.
- During a restore, the Base jobs will be automatically
- pulled in where necessary.
-
- Why: This is something none of the competition does, as far as
- we know (except perhaps BackupPC, which is a Perl program that
- saves to disk only). It is big win for the user, it
- makes Bacula stand out as offering a unique
- optimization that immediately saves time and money.
- Basically, imagine that you have 100 nearly identical
- Windows or Linux machine containing the OS and user
- files. Now for the OS part, a Base job will be backed
- up once, and rather than making 100 copies of the OS,
- there will be only one. If one or more of the systems
- have some files updated, no problem, they will be
- automatically restored.
-
- Notes: Huge savings in tape usage even for a single machine.
- Will require more resources because the DIR must send
- FD a list of files/attribs, and the FD must search the
- list and compare it for each file to be saved.

-Item 10: Scheduling syntax that permits more flexibility and options
+Item 2: Scheduling syntax that permits more flexibility and options
Date: 15 December 2006
Origin: Gregory Brauer (greg at wildbrain dot com) and
Florian Schnabel <florian.schnabel at docufy dot de>
Notes: Kern: I have merged the previously separate project of skipping
jobs (via Schedule syntax) into this.
-Item 11: 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 3: Data encryption on storage daemon
+ Origin: Tobias Barth <tobias.barth at web-arts.com>
+ Date: 04 February 2009
+ Status: new
-Item 12: Bacula Dir, FD and SD to support proxies
-Origin: Karl Grindley @ MIT Lincoln Laboratory <kgrindley at ll dot mit dot edu>
-Date: 25 March 2009
-Status: proposed
+ What: The storage demon should be able to do the data encryption that can
+ currently be done by the file daemon.
-What: Support alternate methods for nailing up a TCP session such
- as SOCKS5, SOCKS4 and HTTP (CONNECT) proxies. Such a feature
- would allow tunneling of bacula traffic in and out of proxied
- networks.
+ 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.
-Why: Currently, bacula is architected to only function on a flat network, with
- no barriers or limitations. Due to the large configuration states of
- any network and the infinite configuration where file daemons and
- storage daemons may sit in relation to one another, bacula often is
- not usable on a network where filtered or air-gaped networks exist.
- While often solutions such as ACL modifications to firewalls or port
- redirection via SNAT or DNAT will solve the issue, often however,
- these solutions are not adequate or not allowed by hard policy.
+ 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:
+ http://www.mail-archive.com/bacula-users@lists.sourceforge.net/msg28860.html
- In an air-gapped network with only a highly locked down proxy services
- are provided (SOCKS4/5 and/or HTTP and/or SSH outbound) ACLs or
- iptable rules will not work.
-Notes: Director resource tunneling: This configuration option to utilize a
- proxy to connect to a client should be specified in the client
- resource Client resource tunneling: should be configured in the client
- resource in the director config file? Or configured on the bacula-fd
- configuration file on the fd host itself? If the ladder, this would
- allow only certain clients to use a proxy, where others do not when
- establishing the TCP connection to the storage server.
+Item 4: 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
- Also worth noting, there are other 3rd party, light weight apps that
- could be utilized to bootstrap this. Instead of sockifing bacula
- itself, use an external program to broker proxy authentication, and
- connection to the remote host. OpenSSH does this by using the
- "ProxyCommand" syntax in the client configuration and uses stdin and
- stdout to the command. Connect.c is a very popular one.
- (http://bent.latency.net/bent/darcs/goto-san-connect-1.85/src/connect.html).
- One could also possibly use stunnel, netcat, etc.
+ 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 13: 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).
+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:
- 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).
+ What: Make Bacula manage tape life cycle information, tape reuse
+ times and drive cleaning cycles.
- Notes: One way this could be done is through additional message types, for example:
+ 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...)
- 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
- }
+ 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.
- Notes: Kern: This should be rather trivial to implement.
+ 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.
-Item 14: Ability to reconnect a disconnected comm line
- Date: 26 April 2009
- Origin: Kern/Eric
- Status:
+ 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.
- 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.
+ 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.
- Why: Avoids backuping data already saved.
+ Implementation of these projects could happen in three distinct
+ sub-projects: Measuring Tape and Drive usage, retiring
+ volumes, and handling drive cleaning and TAPEALERTs.
- Notes: *Very* complicated from a design point of view because of authenication.
+Item 6: Allow FD to initiate a backup
+Origin: Frank Volf (frank at deze dot org)
+Date: 17 November 2005
+Status:
-Item 15: 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
+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 "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
+ 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!

+ What: Using rdiff techniques, Bacula could significantly reduce

+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: 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 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.
+

-What: A directive something like "IncludeConf = /etc/bacula/subconfs" Every

+Item 22: An option to operate on all pools with update vol parameters
+ Origin: Dmitriy Pinchukov <absh@bossdev.kiev.ua>
+ Date: 16 August 2006
+ Status: Patch made by Nigel Stepp
-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

- What: Add a new option to the storage resource of the director. Depending
- on this option, compression will be enabled/disabled for a device.
-
- Why: If different devices (disks/tapes) are used for full/diff/incr
- backups, software compression will be enabled for all backups
- because of the FileSet compression option. For backup to tapes
- wich are able to do hardware compression this is not desired.
-
-
- Notes:
- http://news.gmane.org/gmane.comp.sysutils.backup.bacula.devel/cutoff=11124
- It must be clear to the user, that the FileSet compression option
- must still be enabled use compression for a backup job at all.
- Thus a name for the new option in the director must be
- well-defined.
+ What: When I do update -> Volume parameters -> All Volumes
+ from Pool, then I have to select pools one by one. I'd like

+ Origin: Peter Eriksson <peter at ifm.liu dot se>
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
- be clearly reflected in the documentation, but this is the
- normal Windows SysAdmin's business.
- When "portable" backup is requested the EFS-encrypted files
- 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
- each file, too?
- Unfortunately, the implementation is not as straightforward as
- 1-to-1 replacement of BackupRead with ReadEncryptedFileRaw,
- requiring some FD code rewrite to work with
- encrypted-file-related callback functions.

- Origin: Ralf Gross ralf-lists <at> ralfgross.de
- Date: 2008-12-12
- Status: Initial Request
+ 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.
- What: respect the "Maximum Concurrent Jobs" directive in the _drives_
- Storage section in addition to the changer section
+ 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.
- Why: I have a 3 drive changer where I want to be able to let 3 concurrent
- jobs run in parallel. But only one job per drive at the same time.
- Right now I don't see how I could limit the number of concurrent jobs
- per drive in this situation.
- Notes: Using different priorities for these jobs lead to problems that other
- jobs are blocked. On the user list I got the advice to use the "Prefer Mounted
- Volumes" directive, but Kern advised against using "Prefer Mounted

- 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

- 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

-Date: 12 March 2009
-Status: Proposing
-
-What: The ability to restore from volumes held by multiple storage daemons
- would be very useful.
-
-Why: It is useful to be able to backup to any number of different storage
- daemons. For example, your first storage daemon may run out of space, so you
- switch to your second and carry on. Bacula will currently let you do this.
- However, once you come to restore, bacula cannot cope when volumes on different
- storage daemons are required.
-
- Notes: The director knows that more than one storage daemon is needed, as
- bconsole outputs something like the following table.
-
- The job will require the following
- Volume(s) Storage(s) SD Device(s)
- ===========================================================================
-
- backup-0001 Disk 1 Disk 1.0
- backup-0002 Disk 2 Disk 2.0
-
- However, the bootstrap file that it creates gets sent to the first storage
- daemon only, which then stalls for a long time, 'waiting for a mount request'
- for the volume that it doesn't have.
- The bootstrap file contains no knowledge of the storage daemon.
- Under the current design:
-
- The director connects to the storage daemon, and gets an sd_auth_key.
- The director then connects to the file daemon, and gives it the
- sd_auth_key with the 'jobcmd'.
- (restoring of files happens)
- The director does a 'wait_for_storage_daemon_termination()'.
- The director waits for the file daemon to indicate the end of the job.
-
- With my idea:
-
- The director connects to the file daemon.
- Then, for each storage daemon in the .bsr file... {
- The director connects to the storage daemon, and gets an sd_auth_key.
- The director then connects to the file daemon, and gives it the
- sd_auth_key with the 'storaddr' command.
- (restoring of files happens)
- The director does a 'wait_for_storage_daemon_termination()'.
- The director waits for the file daemon to indicate the end of the
- work on this storage.
- }
- The director tells the file daemon that there are no more storages to contact.
- The director waits for the file daemon to indicate the end of the job.
-
- As you can see, each restore between the file daemon and storage daemon is
- handled in the same way that it is currently handled, using the same method
- for authentication, except that the sd_auth_key is moved from the 'jobcmd' to
- the 'storaddr' command - where it logically belongs.

-
-Status: Proposing
-
-What: Add to the bconsole 'restore' menu the ability to select a job

-
- Why: Currently, you either have to...
- a) laboriously type in a date that is greater than the date of the backup that
- you want and is less than the subsequent backup (bacula then figures out the
- dependent jobs), or
- b) manually figure out all the JobIds that you want and laboriously type them
- all in.
- It would be extremely useful (in a programmatical sense, as well as for humans)
- to be able to just give it a single JobId and let bacula do the hard work (work
- that it already knows how to do).
-
- Notes (Kern): I think this should either be modified to have Bacula print
- a list of dates that the user can choose from as is done in bwx-console and
- bat or the name of this command must be carefully chosen so that the user
- clearly understands that the JobId is being used to specify what Job and the

+Status: proposed
- ## Yearly Backup
+What: Support alternate methods for nailing up a TCP session such

+ would allow tunneling of bacula traffic in and out of proxied
+ networks.
- Run = pool=Yearly last Fri of the Year at 23:50
+Why: Currently, bacula is architected to only function on a flat network, with
+ no barriers or limitations. Due to the large configuration states of
+ any network and the infinite configuration where file daemons and
+ storage daemons may sit in relation to one another, bacula often is
+ not usable on a network where filtered or air-gaped networks exist.
+ While often solutions such as ACL modifications to firewalls or port
+ redirection via SNAT or DNAT will solve the issue, often however,
+ these solutions are not adequate or not allowed by hard policy.
- ## Certain Jobs the last Week of a Month
+ In an air-gapped network with only a highly locked down proxy services
+ are provided (SOCKS4/5 and/or HTTP and/or SSH outbound) ACLs or
+ iptable rules will not work.
- Run = pool=LastWeek last Week of the Month at 23:50
+Notes: Director resource tunneling: This configuration option to utilize a
+ proxy to connect to a client should be specified in the client
+ resource Client resource tunneling: should be configured in the client
+ resource in the director config file? Or configured on the bacula-fd
+ configuration file on the fd host itself? If the ladder, this would
+ allow only certain clients to use a proxy, where others do not when
+ establishing the TCP connection to the storage server.
- ## Monthly Backup on the last day of the month
+ Also worth noting, there are other 3rd party, light weight apps that
+ could be utilized to bootstrap this. Instead of sockifing bacula
+ itself, use an external program to broker proxy authentication, and
+ connection to the remote host. OpenSSH does this by using the
+ "ProxyCommand" syntax in the client configuration and uses stdin and
+ stdout to the command. Connect.c is a very popular one.

- What: Cause Bacula daemons (dir, fd, sd) to always use the ip address

- for initiating communication.
- Why: On complex networks, as well as extremely secure networks, it's
- not unusual to have multiple possible routes through the network.
- Often, each of these routes is secured by different policies
- (effectively, firewalls allow or deny different traffic depending
- on the source address)
- Unfortunately, it can sometimes be difficult or impossible to
- represent this in a system routing table, as the result is
- excessive subnetting that quickly exhausts available IP space.
- The best available workaround is to provide multiple IPs to
- a single machine that are all on the same subnet. In order
- for this to work properly, applications must support the ability
- to bind outgoing connections to a specified address, otherwise
- the operating system will always choose the first IP that
- matches the required route.
- Notes: Many other programs support this. For example, the following
- can be configured in BIND:
- query-source address 10.0.0.1;
- transfer-source 10.0.0.2;
- Which means queries from this server will always come from
- 10.0.0.1 and zone transfers will always originate from
- 10.0.0.2.

+Item 29: Handle Windows Encrypted Files using Win raw encryption
+ Origin: Michael Mohr, SAG Mohr.External@infineon.com
+ Date: 22 February 2008
+ Origin: Alex Ehrlich (Alex.Ehrlich-at-mail.ee)
+ Date: 05 August 2008
+ Status:
- What:
- The ability to tell Bacula which Job should verify instead of
- automatically verify just the last one.
+ 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:
- 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.
+ 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.
-Item 36: Automatic disabling of devices
- Date: 2005-11-11
- Origin: Peter Eriksson <peter at ifm.liu dot se>
- Status:
+ 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
+ be clearly reflected in the documentation, but this is the
+ normal Windows SysAdmin's business.
+ When "portable" backup is requested the EFS-encrypted files
+ 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
+ each file, too?
+ Unfortunately, the implementation is not as straightforward as
+ 1-to-1 replacement of BackupRead with ReadEncryptedFileRaw,
+ requiring some FD code rewrite to work with
+ encrypted-file-related callback functions.
- 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.
+Item 30: 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.
- 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.
+ Why: Amazon's S3 is a cheap way to store data off-site.
-Item 37: An option to operate on all pools with update vol parameters
- Origin: Dmitriy Pinchukov <absh@bossdev.kiev.ua>
- Date: 16 August 2006
- Status: Patch made by Nigel Stepp
+ 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.
- What: When I do update -> Volume parameters -> All Volumes
- from Pool, then I have to select pools one by one. I'd like
- console to have an option like "0: All Pools" in the list of
- defined pools.
+ Cloud should be only used with Copy jobs, users should always have
+ a copy of their data on their site.
- Why: I have many pools and therefore unhappy with manually
- updating each of them using update -> Volume parameters -> All
- Volumes from Pool -> pool #.
+ 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 38: 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 39: 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: Separate Win32 tray monitor to be a separate program.
- What: Make Bacula manage tape life cycle information, tape reuse
- times and drive cleaning cycles.
+ Why: Vista does not allow SYSTEM services to interact with the
+ desktop, so the current tray monitor does not work on Vista
+ machines.
- 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: Requires communicating with the FD via the network (simulate
+ a console connection).
- 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.
+Item 32: Relabel disk volume after recycling
+ Origin: Pasi Kärkkäinen <pasik@iki.fi>
+ Date: 07 May 2009.
+ Status: Not implemented yet, no code written.
- 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.
+ 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}"
- 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.
+ 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.
- Implementation of these projects could happen in three distinct
- sub-projects: Measuring Tape and Drive usage, retiring
- volumes, and handling drive cleaning and TAPEALERTs.
+ Notes: The configuration option could be "Relabel after Recycling = Yes".

+Item 33: Command that releases all drives in an autochanger
+ Origin: Blake Dunlap (blake@nxs.net)
+ Date: 10/07/2009
+ Status: Request
+
+ What: It would be nice if there was a release command that
+ would release all drives in an autochanger instead of having to
+ do each one in turn.
+
+ Why: It can take some time for a release to occur, and the
+ commands must be given for each drive in turn, which can quicky
+ scale if there are several drives in the library. (Having to
+ watch the console, to give each command can waste a good bit of
+ time when you start getting into the 16 drive range when the
+ tapes can take up to 3 minutes to eject each)
+
+ Notes: Due to the way some autochangers/libraries work, you
+ cannot assume that new tapes inserted will go into slots that are
+ not currently believed to be in use by bacula (the tape from that
+ slot is in a drive). This would make any changes in
+ configuration quicker/easier, as all drives need to be released
+ before any modifications to slots.
+
+Item 34: Run bscan on a remote storage daemon from within bconsole.
+ Date: 07 October 2009
+ Origin: Graham Keeling <graham@equiinet.com>
+ Status: Proposing
+
+ What: The ability to be able to run bscan on a remote storage daemon from
+ within bconsole in order to populate your catalog.
+
+ Why: Currently, it seems you have to:
+ a) log in to a console on the remote machine
+ b) figure out where the storage daemon config file is
+ c) figure out the storage device from the config file
+ d) figure out the catalog IP address
+ e) figure out the catalog port
+ f) open the port on the catalog firewall
+ g) configure the catalog database to accept connections from the
+ remote host
+ h) build a 'bscan' command from (b)-(e) above and run it
+ It would be much nicer to be able to type something like this into
+ bconsole:
+ *bscan storage=<storage> device=<device> volume=<volume>
+ or something like:
+ *bscan storage=<storage> all
+ It seems to me that the scan could also do a better job than the
+ external bscan program currently does. It would possibly be able to
+ deduce some extra details, such as the catalog StorageId for the
+ volumes.
+
+ Notes: (Kern). If you need to do a bscan, you have done something wrong,
+ so this functionality should not need to be integrated into the
+ the Storage daemon. However, I am not opposed to someone implementing
+ this feature providing that all the code is in a shared object (or dll)
+ and does not add significantly to the size of the Storage daemon. In
+ addition, the code should be written in a way such that the same source
+ code is used in both the bscan program and the Storage daemon to avoid
+ adding a lot of new code that must be maintained by the project.
+
+Item 35: Implement a Migration job type that will create a reverse
+ incremental (or decremental) backup from two existing full backups.
+ Date: 05 October 2009
+ Origin: Griffith College Dublin. Some sponsorship available.
+ Contact: Gavin McCullagh <gavin.mccullagh@gcd.ie>
+ Status:
- What: I want the file daemon to start multiple threads for a backup
- job so the fastest possible backup can be made.
+ What: The ability to take two full backup jobs and derive a reverse
+ incremental backup from them. The older full backup data may then
+ be discarded.
+
+ Why: Long-term backups based on keeping full backups can be expensive in
+ media. In many cases (eg a NAS), as the client accumulates files
+ over months and years, the same file will be duplicated unchanged,
+ across many media and datasets. Eg, Less than 10% (and
+ shrinking) of our monthly full mail server backup is new files,
+ the other 90% is also in the previous full backup.
+ Regularly converting the oldest full backup into a reverse
+ incremental backup allows the admin to keep access to old backup
+ jobs, but remove all of the duplicated files, freeing up media.

+Item 36: Job migration between different SDs
+Origin: Mariusz Czulada <manieq AT wp DOT eu>
+Date: 07 May 2007
+Status: NEW
+
+What: Allow to specify in migration job devices on Storage Daemon other then
+ the one used for migrated jobs (possibly on different/distant host)
+
+Why: Sometimes we have more then one system which requires backup
+ implementation. Often, these systems are functionally unrelated and
+ placed in different locations. Having a big backup device (a tape
+ library) in each location is not cost-effective. It would be much
+ better to have one powerful enough tape library which could handle
+ backups from all systems, assuming relatively fast and reliable WAN
+ connections. In such architecture backups are done in service windows
+ on local bacula servers, then migrated to central storage off the peak
+ hours.
+
+Notes: If migration to different SD is working, migration to the same SD, as
+ now, could be done the same way (i mean 'localhost') to unify the
+ whole process
+
+Item 37: Concurrent spooling and despooling withini 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.

+ Date: 10 April 2009
+ Origin: Ralf Gross (Ralf-Lists <at> ralfgross.de)
+ Status: not implemented or documented
+
+ What: At the moment a VolumeToCatalog job compares only the
+ last job with the data in the catalog. It's not possible
+ to compare the data (md5sums) of an older volume with the
+ data in the catalog.
+
+ Why: If a verify job fails, one has to immediately check the
+ source of the problem, fix it and rerun the verify job.
+ This has to happen before the next backup of the
+ verified backup job starts.
+ More important: It's not possible to check jobs that are
+ kept for a long time (archiv). If a jobid could be
+ specified for a verify job, older backups/tapes could be
+ checked on a regular base.

+ VolumeToCatalog: This level causes Bacula to read the file
+ attribute data written to the Volume from the last Job [...]
+
+ Verify Job = <Job-Resource-Name> If you run a verify job

+ Date: 29 April 2009
+ Origin: "James Harper" <james.harper@bendigoit.com.au>
+ Status: not implemented or documented
+
+ What: Separate "Storage" and "Device" in the bacula-dir.conf
+ The resulting config would looks something like:
- The file daemon could parse the FileSet information and start
- one thread for each File entry located on a separate
- filesystem.
+ Storage {
+ Name = name_of_server
+ Address = hostname/IP address
+ SDPort = 9103
+ Password = shh_its_a_secret
+ Maximum Concurrent Jobs = 7
+ }
- 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.
+ Device {
+ Name = name_of_device
+ Storage = name_of_server
+ Device = name_of_device_on_sd
+ Media Type = media_type
+ Maximum Concurrent Jobs = 1
+ }
- If the theads could spool the data to separate spool files
- the restore process will not be much slower.
+ Maximum Concurrent Jobs would be specified with a server and a device
+ maximum, which would both be honoured by the director. Almost everything
+ that mentions a 'Storage' would need to be changed to 'Device', although
+ perhaps a 'Storage' would just be a synonym for 'Device' for backwards
+ compatibility...
- Why: Multiple concurrent backups of a large fileserver with many
- disks and controllers will be much faster.
+ Why: If you have multiple Storage definitions pointing to different
+ Devices in the same Storage daemon, the "status storage" command
+ prompts for each different device, but they all give the same
+ information.

+Status: Proposal
-Item 1: Relabel disk volume after recycling
- Origin: Pasi Kärkkäinen <pasik@iki.fi>
- Date: 07 May 2009.
- Status: Not implemented yet, no code written.
+What: A better tape drive selection algorithm for multi-drive
+ autochangers. The AUTOCHANGER class contains an array list of tape
+ devices. When a tape drive is needed, this list is always searched in
+ order. This causes lower number drives (specifically drive 0) to do a
+ majority of the work with higher numbered drives possibly never being
+ used. When a drive in an autochanger is reserved for use, its entry should
+ be moved to the end of the list; this would give a rough LRU drive
+ selection.
- 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: The current implementation places a majority of use and wear on drive
+ 0 of a multi-drive autochanger.
- 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:
