-Item 1: Accurate restoration of renamed/deleted files
- Date: 28 November 2005
- Origin: Martin Simmons (martin at lispworks dot com)
- Status:
-
- What: When restoring a fileset for a specified date (including "most
- recent"), Bacula should give you exactly the files and directories
- that existed at the time of the last backup prior to that date.
-
- Currently this only works if the last backup was a Full backup.
- When the last backup was Incremental/Differential, files and
- directories that have been renamed or deleted since the last Full
- backup are not currently restored correctly. Ditto for files with
- extra/fewer hard links than at the time of the last Full backup.
-
- Why: Incremental/Differential would be much more useful if this worked.
-
- Notes: Merging of multiple backups into a single one seems to
- rely on this working, otherwise the merged backups will not be
- truly equivalent to a Full backup.
-
- Note: Kern: notes shortened. This can be done without the need for
- inodes. It is essentially the same as the current Verify job,
- but one additional database record must be written, which does
- not need any database change.
-
- Notes: Kern: see if we can correct restoration of directories if
- replace=ifnewer is set. Currently, if the directory does not
- exist, a "dummy" directory is created, then when all the files
- are updated, the dummy directory is newer so the real values
- are not updated.
-
Item 2: Allow FD to initiate a backup
Origin: Frank Volf (frank at deze dot org)
Date: 17 November 2005
Why: Makes backup of laptops much easier.
-Item 3: Merge multiple backups (Synthetic Backup or Consolidation)
- Origin: Marc Cousin and Eric Bollengier
- Date: 15 November 2005
- Status:
-
- What: A merged backup is a backup made without connecting to the Client.
- It would be a Merge of existing backups into a single backup.
- In effect, it is like a restore but to the backup medium.
-
- For instance, say that last Sunday we made a full backup. Then
- all week long, we created incremental backups, in order to do
- them fast. Now comes Sunday again, and we need another full.
- The merged backup makes it possible to do instead an incremental
- backup (during the night for instance), and then create a merged
- backup during the day, by using the full and incrementals from
- the week. The merged backup will be exactly like a full made
- Sunday night on the tape, but the production interruption on the
- Client will be minimal, as the Client will only have to send
- incrementals.
-
- In fact, if it's done correctly, you could merge all the
- Incrementals into single Incremental, or all the Incrementals
- and the last Differential into a new Differential, or the Full,
- last differential and all the Incrementals into a new Full
- backup. And there is no need to involve the Client.
-
- Why: The benefit is that :
- - the Client just does an incremental ;
- - the merged backup on tape is just as a single full backup,
- and can be restored very fast.
-
- This is also a way of reducing the backup data since the old
- data can then be pruned (or not) from the catalog, possibly
- allowing older volumes to be recycled
-
-Item 4: Implement Catalog directive for Pool resource in Director
- Origin: Alan Davis adavis@ruckus.com
- Date: 6 March 2007
- Status: Submitted
-
- What: The current behavior is for the director to create all pools
- found in the configuration file in all catalogs. Add a
- Catalog directive to the Pool resource to specify which
- catalog to use for each pool definition.
-
- Why: This allows different catalogs to have different pool
- attributes and eliminates the side-effect of adding
- pools to catalogs that don't need/use them.
-
- Notes: Kern: I think this is relatively easy to do, and it is really
- a pre-requisite to a number of the Copy pool, ... projects
- that are listed here.
-
-Item 5: Add an item to the restore option where you can select a Pool
- Origin: kshatriyak at gmail dot com
- Date: 1/1/2006
- Status:
-
- What: In the restore option (Select the most recent backup for a
- client) it would be useful to add an option where you can limit
- the selection to a certain pool.
-
- Why: When using cloned jobs, most of the time you have 2 pools - a
- disk pool and a tape pool. People who have 2 pools would like to
- select the most recent backup from disk, not from tape (tape
- would be only needed in emergency). However, the most recent
- backup (which may just differ a second from the disk backup) may
- be on tape and would be selected. The problem becomes bigger if
- you have a full and differential - the most "recent" full backup
- may be on disk, while the most recent differential may be on tape
- (though the differential on disk may differ even only a second or
- so). Bacula will complain that the backups reside on different
- media then. For now the only solution now when restoring things
- when you have 2 pools is to manually search for the right
- job-id's and enter them by hand, which is a bit fault tolerant.
-
- Notes: Kern: This is a nice idea. It could also be the way to support
- Jobs that have been Copied (similar to migration, but not yet
- implemented).
-

Item 6: Deletion of disk Volumes when pruned
Date: Nov 25, 2005
list and compare it for each file to be saved.
-Item 8: Implement Copy pools
- Date: 27 November 2005
- Origin: David Boyes (dboyes at sinenomine dot net)
- Status:
-
- What: I would like Bacula to have the capability to write copies
- of backed-up data on multiple physical volumes selected
- from different pools without transferring the data
- multiple times, and to accept any of the copy volumes
- as valid for restore.
-
- Why: In many cases, businesses are required to keep offsite
- copies of backup volumes, or just wish for simple
- protection against a human operator dropping a storage
- volume and damaging it. The ability to generate multiple
- volumes in the course of a single backup job allows
- customers to simple check out one copy and send it
- offsite, marking it as out of changer or otherwise
- unavailable. Currently, the library and magazine
- management capability in Bacula does not make this process
- simple.
-
- Restores would use the copy of the data on the first
- available volume, in order of Copy pool chain definition.
-
- This is also a major scalability issue -- as the number of
- clients increases beyond several thousand, and the volume
- of data increases, transferring the data multiple times to
- produce additional copies of the backups will become
- physically impossible due to transfer speed
- issues. Generating multiple copies at server side will
- become the only practical option.
-
- How: I suspect that this will require adding a multiplexing
- SD that appears to be a SD to a specific FD, but 1-n FDs
- to the specific back end SDs managing the primary and copy
- pools. Storage pools will also need to acquire parameters
- to define the pools to be used for copies.
-
- Notes: I would commit some of my developers' time if we can agree
- on the design and behavior.
-
- Notes: Additional notes from David:
- I think there's two areas where new configuration would be needed.
-
- 1) Identify a "SD mux" SD (specify it in the config just like a normal
- SD. The SD configuration would need something like a "Daemon Type =
- Normal/Mux" keyword to identify it as a multiplexor. (The director code
- would need modification to add the ability to do the multiple session
- setup, but the impact of the change would be new code that was invoked
- only when a SDmux is needed).
-
- 2) Additional keywords in the Pool definition to identify the need to
- create copies. Each pool would acquire a Copypool= attribute (may be
- repeated to generate more than one copy. 3 is about the practical limit,
- but no point in hardcoding that).
-
- Example:
- Pool {
- Name = Primary
- Pool Type = Backup
- Copypool = Copy1
- Copypool = OffsiteCopy2
- }
-
- where Copy1 and OffsiteCopy2 are valid pools.
-
- In terms of function (shorthand):
- Backup job X is defined normally, specifying pool Primary as the pool to
- use. Job gets scheduled, and Bacula starts scheduling resources.
- Scheduler looks at pool definition for Primary, sees that there are a
- non-zero number of copypool keywords. The director then connects to an
- available SDmux, passes it the pool ids for Primary, Copy1, and
- OffsiteCopy2 and waits. SDmux then goes out and reserves devices and
- volumes in the normal SDs that serve Primary, Copy1 and OffsiteCopy2.
- When all are ready, the SDmux signals ready back to the director, and
- the FD is given the address of the SDmux as the SD to communicate with.
- Backup proceeds normally, with the SDmux duplicating blocks to each
- connected normal SD, and returning ready when all defined copies have
- been written. At EOJ, FD shuts down connection with SDmux, which closes
- down the normal SD connections and goes back to an idle state.
- SDmux does not update database; normal SDs do (noting that file is
- present on each volume it has been written to).
-
- On restore, director looks for the volume containing the file in pool
- Primary first, then Copy1, then OffsiteCopy2. If the volume holding the
- file in pool Primary is missing or busy (being written in another job,
- etc), or one of the volumes from the copypool list that have the file in
- question is already mounted and ready for some reason, use it to do the
- restore, else mount one of the copypool volumes and proceed.

Item 9: Scheduling syntax that permits more flexibility and options
Date: 15 December 2006
Origin: Gregory Brauer (greg at wildbrain dot com) and
10.0.0.2.
-Item 12: Add Plug-ins to the FileSet Include statements.
- Date: 28 October 2005
- Origin: Kern
- Status: Partially coded in 1.37 -- much more to do.
-
- What: Allow users to specify wild-card and/or regular
- expressions to be matched in both the Include and
- Exclude directives in a FileSet. At the same time,
- allow users to define plug-ins to be called (based on
- regular expression/wild-card matching).
-
- Why: This would give the users the ultimate ability to control
- how files are backed up/restored. A user could write a
- plug-in knows how to backup his Oracle database without
- stopping/starting it, for example.
-
-
-Item 13: Restore only file attributes (permissions, ACL, owner, group...)
- Origin: Eric Bollengier
- Date: 30/12/2006
- Status: Implemented by Eric, see project-restore-attributes-only.patch
-
- What: The goal of this project is to be able to restore only rights
- and attributes of files without crushing them.
-
- Why: Who have never had to repair a chmod -R 777, or a wild update
- of recursive right under Windows? At this time, you must have
- enough space to restore data, dump attributes (easy with acl,
- more complex with unix/windows rights) and apply them to your
- broken tree. With this options, it will be very easy to compare
- right or ACL over the time.
-
- Notes: If the file is here, we skip restore and we change rights.
- If the file isn't here, we can create an empty one and apply
- rights or do nothing.
-
- This will not work with win32 stream, because it seems that we
- can't split the WriteBackup stream to get only ACL and ownerchip.
-
Item 14: Add an override in Schedule for Pools based on backup types
Date: 19 Jan 2005
Origin: Chad Slater <chad.slater@clickfox.com>
Item 15: Implement more Python events and functions
Date: 28 October 2005
Origin: Kern
- Status:
+ Status: Project abandoned in favor of plugins.
What: Allow Python scripts to be called at more places
within Bacula and provide additional access to Bacula
Amanda can do and we can't (at least, the one cool thing I know of).
-Item 18: Better control over Job execution
- Date: 18 August 2007
- Origin: Kern
- Status:
-
- What: Bacula needs a few extra features for better Job execution:
- 1. A way to prevent multiple Jobs of the same name from
- being scheduled at the same time (ususally happens when
- a job is missed because a client is down).
- 2. Directives that permit easier upgrading of Job types
- based on a period of time. I.e. "do a Full at least
- once every 2 weeks", or "do a differential at least
- once a week". If a lower level job is scheduled when
- it begins to run it will be upgraded depending on
- the specified criteria.
-
- Why: Obvious.

Item 19: Automatic disabling of devices

Origin: Peter Eriksson <peter at ifm.liu dot se>

+========= New Items since the last vote =================
+
+Item 26: Add a new directive to bacula-dir.conf which permits inclusion of all subconfiguration files in a given 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
-========== Items on put hold by Kern ============================
+ Item n: 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

+ 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 1: Implement an interface between Bacula and 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. Current
+ ways to integrate Bacula and S3 involve storing all the data
+ locally and syncing them to S3, and manually fetching them
+ again when they're needed. This is very cumbersome.
-Item h1: Split documentation
- Origin: Maxx <maxxatworkat gmail dot com>
- Date: 27th July 2006
- Status: Approved, awaiting implementation
- What: Split documentation in several books
+Item 1: enable/disable compression depending on storage device (disk/tape)
+ Origin: Ralf Gross ralf-lists@ralfgross.de
+ Date: 2008-01-11
+ Status: Initial Request
- Why: Bacula manual has now more than 600 pages, and looking for
- implementation details is getting complicated. I think
- it would be good to split the single volume in two or
- maybe three parts:
+ What: Add a new option to the storage resource of the director. Depending
+ on this option, compression will be enabled/disabled for a device.
- 1) Introduction, requirements and tutorial, typically
- are useful only until first installation time
+ 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.
+
- 2) Basic installation and configuration, with all the
- gory details about the directives supported 3)
- Advanced Bacula: testing, troubleshooting, GUI and
- ancillary programs, security managements, scripting,
- etc.
+ 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.
- Notes: This is a project that needs to be done, and will be implemented,
- but it is really a developer issue of timing, and does not
- needed to be included in the voting.
+ Notes: KES I think the Storage definition should probably override what
+ is in the Job definition or vice-versa, but in any case, it must
+ be well defined.

+Item 1: Backup and Restore of Windows Encrypted Files through raw encryption
+ functions
+
+ Origin: Michael Mohr, SAG Mohr.External@infineon.com
+
+ Date: 22 February 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.
+
+ 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 1: 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
+
+ ## 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
+
+ Date: 20 March 2008
+
+ Origin: Frank Sweetser <fs@wpi.edu>
+
+ What: Add a new SD directive, "minimum spool size" (or similar). This
+ directive would specify a minimum level of free space available for
+ spooling. If the unused spool space is less than this level, any
+ new spooling requests would be blocked as if the "maximum spool
+ size" threshold had bee reached. Already spooling jobs would be
+ unaffected by this directive.
+
+ Why: I've been bitten by this scenario a couple of times:
+
+ Assume a maximum spool size of 100M. Two concurrent jobs, A and B,
+ are both running. Due to timing quirks and previously running jobs,
+ job A has used 99.9M of space in the spool directory. While A is
+ busy despooling to disk, B is happily using the remaining 0.1M of
+ spool space. This ends up in a spool/despool sequence every 0.1M of
+ data. In addition to fragmenting the data on the volume far more
+ than was necessary, in larger data sets (ie, tens or hundreds of
+ gigabytes) it can easily produce multi-megabyte report emails!
+
+ Item n?: Expand the Verify Job capability to verify Jobs older than the
+ last one. For VolumeToCatalog Jobs
+ Date: 17 Januar 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 X: Add EFS support on Windows
+ Origin: Alex Ehrlich (Alex.Ehrlich-at-mail.ee)
+ Date: 05 August 2008
+ Status:
+
+ What: 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: Many laptop users utilize the EFS functionality today; so do.
+ some non-laptop ones, too.
+ Currently files encrypted by means of EFS cannot be backed up.
+ It means a Windows boutique cannot rely on Bacula as its
+ backup solution, at least when using Windows 2K, XPP,
+ "better" Vista etc on workstations, unless EFS is
+ forbidden by policies.
+ The current situation might result into "false sense of
+ security" among the end-users.
+
+ 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.
+
+Item n: 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, and 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 1: "Maximum Concurrent Jobs" for drives when used with changer device
+ Origin: Ralf Gross ralf-lists <at> ralfgross.de
+ Date: 2008-12-12
+ Status: Initial Request
+ What: respect the "Maximum Concurrent Jobs" directive in the _drives_
+ Storage section in addition to the changer section
+
+ 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

+ Item n: Add MaxVolumeSize/MaxVolumeBytes statement to Storage resource
+ Origin: Bastian Friedrich <bastian.friedrich@collax.com>
+ Date: 2008-07-09
+ Status: -
+
+ 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 resources.
+
+ 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: State of idea currently unknown. Storage resources in the dir
+ config currently translate to very slim catalog entries; these entries
+ would require extensions to implement what is described here. Quite
+ possibly, numerous other statements that are currently available in Pool
+ resources could be used in Storage resources too quite well.

+Item 1: 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 1: enable persistent naming/number of SQL queries
+
+ Date: 24 Jan, 2007
+ Origin: Mark Bergman
+ Status:
+
+ What:
+ Change the parsing of the query.sql file and the query command so that
+ queries are named/numbered by a fixed value, not their order in the
+ file.
+
+
+ Why:
+ One of the real strengths of bacula is the ability to query the
+ database, and the fact that complex queries can be saved and
+ referenced from a file is very powerful. However, the choice
+ of query (both for interactive use, and by scripting input
+ to the bconsole command) is completely dependent on the order
+ within the query.sql file. The descriptve labels are helpful for
+ interactive use, but users become used to calling a particular
+ query "by number", or may use scripts to execute queries. This
+ presents a problem if the number or order of queries in the file
+ changes.
+
+ If the query.sql file used the numeric tags as a real value (rather
+ than a comment), then users could have a higher confidence that they
+ are executing the intended query, that their local changes wouldn't
+ conflict with future bacula upgrades.
+
+ For scripting, it's very important that the intended query is
+ what's actually executed. The current method of parsing the
+ query.sql file discourages scripting because the addition or
+ deletion of queries within the file will require corresponding
+ changes to scripts. It may not be obvious to users that deleting
+ query "17" in the query.sql file will require changing all
+ references to higher numbered queries. Similarly, when new
+ bacula distributions change the number of "official" queries,
+ user-developed queries cannot simply be appended to the file
+ without also changing any references to those queries in scripts
+ or procedural documentation, etc.
+
+ In addition, using fixed numbers for queries would encourage more
+ user-initiated development of queries, by supporting conventions
+ such as:
+
+ queries numbered 1-50 are supported/developed/distributed by
+ with official bacula releases
+
+ queries numbered 100-200 are community contributed, and are
+ related to media management
+
+ queries numbered 201-300 are community contributed, and are
+ related to checksums, finding duplicated files across
+ different backups, etc.
+
+ queries numbered 301-400 are community contributed, and are
+ related to backup statistics (average file size, size per
+ client per backup level, time for all clients by backup level,
+ storage capacity by media type, etc.)
+
+ queries numbered 500-999 are locally created
+
+ Notes:
+ Alternatively, queries could be called by keyword (tag), rather
+ than by number.

+Item 1: Implementation of running Job speed limit.
+Origin: Alex F, alexxzell at yahoo dot com
+Date: 29 January 2009
+
+What: I noticed the need for an integrated bandwidth limiter for
+ running jobs. It would be very useful just to specify another
+ field in bacula-dir.conf, like speed = how much speed you wish
+ for that specific job to run at
+
+Why: Because of a couple of reasons. First, it's very hard to implement a
+ traffic shaping utility and also make it reliable. Second, it is very
+ uncomfortable to have to implement these apps to, let's say 50 clients
+ (including desktops, servers). This would also be unreliable because you
+ have to make sure that the apps are properly working when needed; users
+ could also disable them (accidentally or not). It would be very useful
+ to provide Bacula this ability. All information would be centralized,
+ you would not have to go to 50 different clients in 10 different
+ locations for configuration; eliminating 3rd party additions help in
+ establishing efficiency. Would also avoid bandwidth congestion,
+ especially where there is little available.

+Item n: Restore from volumes on multiple storage daemons
+Origin: Graham Keeling (graham@equiinet.com)
+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.

+Item n:'restore' menu: enter a JobId, automatically select dependents
+Origin: Graham Keeling (graham@equiinet.com)
+Date: 13 March 2009
+
+Status: Proposing
+
+What: Add to the bconsole 'restore' menu the ability to select a job
+ by JobId, and have bacula automatically select all the dependent jobs.
+
+ 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
+ date to which he wishes the restore to happen.

+Item 1: 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: 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: 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.
+
+ 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. Storage
+ resource tunneling: right now bacula does not initiate TCP session
+ from the storage resource, however, if Item 2 is implemented, proxy
+ support would be highly desired here as well.
+
+ 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.

Item h8: Incorporation of XACML2/SAML2 parsing

- Now, obviously, Bacula already handles NTFS just fine. However, I

- Date: 28 December 2007
- Origin: Frank Sweetser <fs@wpi.edu>
- What: The ability to store and restore extended attributes on
- filesystems that support them, such as ext3.
-
- Why: Security Enhanced Linux (SELinux) enabled systems make extensive
- use of extended attributes. In addition to the standard user,
- group, and permission, each file has an associated SELinux context
- stored as an extended attribute. This context is used to define
- which operations a given program is permitted to perform on that
- file. Storing contexts on an SELinux system is as critical as
- storing ownership and permissions. In the case of a full system
- restore, the system will not even be able to boot until all
- critical system files have been properly relabeled.
-
- Notes: Fedora ships with a version of tar that has been patched to handle
- extended attributes. The patch has not been integrated upstream
- yet, so could serve as a good starting point.

- 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

-
-
- 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.

- 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.

- both running. Due to timing quirks and previously running jobs, job A
- has used 99.9M of space in the spool directory. While A is busy
- despooling to disk, B is happily using the remaining 0.1M of spool
- space. This ends up in a spool/despool sequence every 0.1M of data.
- In addition to fragmenting the data on the volume far more than was
- necessary, in larger data sets (ie, tens or hundreds of gigabytes) it
- can easily produce multi-megabyte report emails!

-Item n: make changing "spooldata=yes|no" possible for
- manual/interactive jobs
- Origin: Marc Schiffbauer <marc@schiffbauer.net>
- Date: 12 April 2007)
- Status:
-
- What: Make it possible to modify the spooldata option
- for a job when being run from within the console.
- Currently it is possible to modify the backup level
- and the spooldata setting in a Schedule resource.
- It is also possible to modify the backup level when using
- the "run" command in the console.
- But it is currently not possible to to the same
- with "spooldata=yes|no" like:
-
- run job=MyJob level=incremental spooldata=yes
-
- Why: In some situations it would be handy to be able to switch
- spooldata on or off for interactive/manual jobs based on
- which data the admin expects or how fast the LAN/WAN
- connection currently is.
