-
-Item 1:   Implement Migration that moves Jobs from one Pool to another.
-  Origin: Sponsored by Riege Software International GmbH. Contact:
-          Daniel Holtkamp <holtkamp at riege dot com>
-  Date:   28 October 2005
-  Status: Partially coded in 1.37 -- much more to do. Assigned to
-          Kern.
-
-  What:   The ability to copy, move, or archive data that is on a
-          device to another device is very important. 
-
-  Why:    An ISP might want to backup to disk, but after 30 days
-          migrate the data to tape backup and delete it from
-          disk.  Bacula should be able to handle this
-          automatically.  It needs to know what was put where,
-          and when, and what to migrate -- it is a bit like
-          retention periods.  Doing so would allow space to be
-          freed up for current backups while maintaining older
-          data on tape drives.
-
-  Notes:   Riege Software have asked for the following migration
-           triggers:
-           Age of Job
-           Highwater mark (stopped by Lowwater mark?)
-                            
-  Notes:  Migration could be additionally triggered by:
-           Number of Jobs
-           Number of Volumes
-
-
-Item 2:   Implement extraction of Win32 BackupWrite data.
-  Origin: Thorsten Engel <thorsten.engel at matrix-computer dot com>
-  Date:   28 October 2005
-  Status: Assigned to Thorsten. Implemented in current CVS
-
-  What:   This provides the Bacula File daemon with code that
-          can pick apart the stream output that Microsoft writes
-          for BackupWrite data, and thus the data can be read
-          and restored on non-Win32 machines.
-
-  Why:    BackupWrite data is the portable=no option in Win32
-          FileSets, and in previous Baculas, this data could
-          only be extracted using a Win32 FD. With this new code,
-          the Windows data can be extracted and restored on
-          any OS.
-
-
-Item 3:   Implement a Bacula GUI/management tool using Python.
-  Origin: Kern
-  Date:   28 October 2005
-  Status: 
-
-  What:   Implement a Bacula console, and management tools
-          using Python and Qt or GTK.
-
-  Why:    Don't we already have a wxWidgets GUI?  Yes, but
-          it is written in C++ and changes to the user interface
-          must be hand tailored using C++ code. By developing
-          the user interface using Qt designer, the interface
-          can be very easily updated and most of the new Python       
-          code will be automatically created.  The user interface
-          changes become very simple, and only the new features
-          must be implement.  In addition, the code will be in
-          Python, which will give many more users easy (or easier)
-          access to making additions or modifications.

+Item  2:  Allow FD to initiate a backup
+  Origin: Frank Volf (frank at deze dot org)
+  Date:   17 November 2005
+  Status:
 
- Notes:   This is currently being implemented using Python-GTK by       
-          Lucas Di Pentima <lucas at lunix dot com dot ar>
+   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 4:   Implement a Python interface to the Bacula catalog.
-  Date:   28 October 2005
-  Origin: Kern
-  Status: 
 
-  What:   Implement an interface for Python scripts to access
-          the catalog through Bacula.
 
-  Why:    This will permit users to customize Bacula through
-          Python scripts.
+Item  6:  Deletion of disk Volumes when pruned
+  Date:   Nov 25, 2005
+  Origin: Ross Boylan <RossBoylan at stanfordalumni dot org> (edited
+          by Kern)
+  Status:         
 
-Item 5:   Implement more Python events in Bacula.
-  Date:   28 October 2005
-  Origin: 
-  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.
 
-  What:   Allow Python scripts to be called at more places 
-          within Bacula and provide additional access to Bacula
-          internal variables.
+  Why:    This would allow users more control over their Volumes and
+          prevent disk based volumes from consuming too much space.
 
-  Why:    This will permit users to customize Bacula through
-          Python scripts.
+  Notes:  The following two directives might do the trick:
 
-  Notes:  Recycle event
-          Scratch pool event
-          NeedVolume event
-          MediaFull event
-           
-          Also add a way to get a listing of currently running
-          jobs (possibly also scheduled jobs).
+          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.

+Item  9:  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>
+  Status:
 
-  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.
+   What:  Currently, Bacula only understands how to deal with weeks of the
+          month or weeks of the year in schedules.  This makes it impossible
+          to do a true weekly rotation of tapes.  There will always be a
+          discontinuity that will require disruptive manual intervention at
+          least monthly or yearly because week boundaries never align with
+          month or year boundaries.
+
+          A solution would be to add a new syntax that defines (at least)
+          a start timestamp, and repetition period.
+
+          An easy option to skip a certain job  on a certain date.
+   
+
+     Why: Rotated backups done at weekly intervals are useful, and Bacula
+          cannot currently do them without extensive hacking.
+
+          You could then easily skip tape backups on holidays.  Especially
+          if you got no autochanger and can only fit one backup on a tape
+          that would be really handy, other jobs could proceed normally
+          and you won't get errors that way.
+
+
+   Notes: Here is an example syntax showing a 3-week rotation where full
+          Backups would be performed every week on Saturday, and an
+          incremental would be performed every week on Tuesday.  Each
+          set of tapes could be removed from the loader for the following
+          two cycles before coming back and being reused on the third
+          week.  Since the execution times are determined by intervals
+          from a given point in time, there will never be any issues with
+          having to adjust to any sort of arbitrary time boundary.  In
+          the example provided, I even define the starting schedule
+          as crossing both a year and a month boundary, but the run times
+          would be based on the "Repeat" value and would therefore happen
+          weekly as desired.
+
+
+          Schedule {
+              Name = "Week 1 Rotation"
+              #Saturday.  Would run Dec 30, Jan 20, Feb 10, etc.

+Item 10:  Message mailing based on backup types
+ Origin:  Evan Kaufman <evan.kaufman@gmail.com>
+   Date:  January 6, 2006
+ Status:
+
+   What:  In the "Messages" resource definitions, allowing messages
+          to be mailed based on the type (backup, restore, etc.) and level
+          (full, differential, etc) of job that created the originating
+          message(s).
+
+ Why:     It would, for example, allow someone's boss to be emailed
+          automatically only when a Full Backup job runs, so he can
+          retrieve the tapes for offsite storage, even if the IT dept.
+          doesn't (or can't) explicitly notify him.  At the same time, his
+          mailbox wouldnt be filled by notifications of Verifies, Restores,
+          or Incremental/Differential Backups (which would likely be kept
+          onsite).
+
+ Notes:   One way this could be done is through additional message types, for example:
+
+   Messages {
+     # email the boss only on full system backups
+     Mail = boss@mycompany.com = full, !incremental, !differential, !restore, 
+            !verify, !admin
+     # email us only when something breaks
+     MailOnError = itdept@mycompany.com = all
+   }
+
+   Notes: Kern: This should be rather trivial to implement.
+
+
+Item 11:  Cause daemons to use a specific IP address to source communications
+ Origin:  Bill Moran <wmoran@collaborativefusion.com>
+ Date:    18 Dec 2006
+ Status:
+ What:    Cause Bacula daemons (dir, fd, sd) to always use the ip address
+          specified in the [DIR|DF|SD]Addr directive as the source IP
+          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 14:  Add an override in Schedule for Pools based on backup types
+Date:     19 Jan 2005
+Origin:   Chad Slater <chad.slater@clickfox.com>
+Status: 
+                                                
+  What:   Adding a FullStorage=BigTapeLibrary in the Schedule resource
+          would help those of us who use different storage devices for different
+          backup levels cope with the "auto-upgrade" of a backup.
+
+  Why:    Assume I add several new devices to be backed up, i.e. several
+          hosts with 1TB RAID.  To avoid tape switching hassles, incrementals are
+          stored in a disk set on a 2TB RAID.  If you add these devices in the
+          middle of the month, the incrementals are upgraded to "full" backups,
+          but they try to use the same storage device as requested in the
+          incremental job, filling up the RAID holding the differentials.  If we
+          could override the Storage parameter for full and/or differential
+          backups, then the Full job would use the proper Storage device, which
+          has more capacity (i.e. a 8TB tape library.

   Date:   28 October 2005
   Origin: Kern
-  Status: 
+  Status: Project abandoned in favor of plugins.
 
-  What:   Allow users to specify very large exclude list (currently
-          more than about 1000 files is too many).
+  What:   Allow Python scripts to be called at more places 
+          within Bacula and provide additional access to Bacula
+          internal variables.
 
-  Why:    This would give the users the ability to exclude all
-          files that are loaded with the OS (e.g. using rpms
-          or debs). If the user can restore the base OS from
-          CDs, there is no need to backup all those files. A
-          complete restore would be to restore the base OS, then
-          do a Bacula restore. By excluding the base OS files, the
-          backup set will be *much* smaller.
+          Implement an interface for Python scripts to access the
+          catalog through Bacula.
 
+  Why:    This will permit users to customize Bacula through
+          Python scripts.
 
-Item  9:  Implement data encryption (as opposed to comm encryption)
-  Date:   28 October 2005
-  Origin: Sponsored by Landon and 13 contributors to EFF.
-  Status: Landon Fuller is currently implementing this.
-                  
-  What:   Currently the data that is stored on the Volume is not
-          encrypted. For confidentiality, encryption of data at
-          the File daemon level is essential. 
-          Data encryption encrypts the data in the File daemon and
-          decrypts the data in the File daemon during a restore.
-
-  Why:    Large sites require this.

-Item 10:  Permit multiple Media Types in an Autochanger
-  Origin: Kern
-  Status: Now implemented
+  Notes:  Recycle event
+          Scratch pool event
+          NeedVolume event
+          MediaFull event
+           
+          Also add a way to get a listing of currently running
+          jobs (possibly also scheduled jobs).
 
-  What:   Modify the Storage daemon so that multiple Media Types
-          can be specified in an autochanger. This would be somewhat
-          of a simplistic implementation in that each drive would
-          still be allowed to have only one Media Type.  However,
-          the Storage daemon will ensure that only a drive with
-          the Media Type that matches what the Director specifies
-          is chosen.
 
-  Why:    This will permit user with several different drive types
-          to make full use of their autochangers.

-Item 11:  Allow different autochanger definitions for one autochanger.
-  Date:   28 October 2005
-  Origin: Kern
-  Status: 
 
-  What:   Currently, the autochanger script is locked based on
-          the autochanger. That is, if multiple drives are being
-          simultaneously used, the Storage daemon ensures that only
-          one drive at a time can access the mtx-changer script.
-          This change would base the locking on the control device,
-          rather than the autochanger. It would then permit two autochanger
-          definitions for the same autochanger, but with different 
-          drives. Logically, the autochanger could then be "partitioned"
-          for different jobs, clients, or class of jobs, and if the locking
-          is based on the control device (e.g. /dev/sg0) the mtx-changer
-          script will be locked appropriately.
-
-  Why:    This will permit users to partition autochangers for specific
-          use. It would also permit implementation of multiple Media
-          Types with no changes to the Storage daemon.

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

   Status: 
 
-  What:   Implement a red/black binary tree class. This could 
-          then replace the current binary insert/search routines
-          used in the restore in memory tree.  This could significantly
-          speed up the creation of the in memory restore tree.
+    What: Amanda has a feature whereby it estimates the space that a  
+          differential, incremental, and full backup would take.  If the  
+          difference in space required between the scheduled level and the next  
+          level up is beneath some user-defined critical threshold, the backup  
+          level is bumped to the next type.  Doing this minimizes the number of  
+          volumes necessary during a restore, with a fairly minimal cost in  
+          backup media space.
+
+    Why:  I know at least one (quite sophisticated and smart) user  
+          for whom the absence of this feature is a deal-breaker in terms of  
+          using Bacula; if we had it it would eliminate the one cool thing

+  Origin: Peter Eriksson <peter at ifm.liu dot se>
+  Status:
+
+   What:  After a configurable amount of fatal errors with a tape drive
+          Bacula should automatically disable further use of a certain
+          tape drive. There should also be "disable"/"enable" commands in
+          the "bconsole" tool.
+
+   Why:   On a multi-drive jukebox there is a possibility of tape drives
+          going bad during large backups (needing a cleaning tape run,
+          tapes getting stuck). It would be advantageous if Bacula would
+          automatically disable further use of a problematic tape drive
+          after a configurable amount of errors has occurred.
+
+          An example: I have a multi-drive jukebox (6 drives, 380+ slots)
+          where tapes occasionally get stuck inside the drive. Bacula will
+          notice that the "mtx-changer" command will fail and then fail
+          any backup jobs trying to use that drive. However, it will still
+          keep on trying to run new jobs using that drive and fail -
+          forever, and thus failing lots and lots of jobs... Since we have
+          many drives Bacula could have just automatically disabled
+          further use of that drive and used one of the other ones
+          instead.

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

+
+  Why:    Including the timestamp would make it much easier to decide whether

+
+  Notes:  It may be helpful to have the output from "stat clients" formatted

+  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 14:  Merge multiple backups (Synthetic Backup or Consolidation).
-  Origin: Marc Cousin and Eric Bollengier 
-  Date:   15 November 2005
-  Status: Depends on first implementing project Item 1 (Migration).
-
-  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

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

-          file would be backed up when it is changed.
-
-  Why:    This would save lots of space when backing up large files such as 
-          logs, mbox files, Outlook PST files and the like.
-
-  Notes:  This would require the usage of disk-based volumes as comparing

-Item 17:  Quick release of FD-SD connection after backup.
-  Origin: Frank Volf (frank at deze dot org)
-  Date:   17 November 2005
-  Status:
-
-   What:  In the Bacula implementation a backup is finished after all data
-          and attributes are successfully written to storage.  When using a
-          tape backup it is very annoying that a backup can take a day,
-          simply because the current tape (or whatever) is full and the
-          administrator has not put a new one in.  During that time the
-          system cannot be taken off-line, because there is still an open
-          session between the storage daemon and the file daemon on the
-          client.
-
-          Although this is a very good strategy for making "safe backups"
-          This can be annoying for e.g.  laptops, that must remain
-          connected until the backup is completed.
-
-          Using a new feature called "migration" it will be possible to
-          spool first to harddisk (using a special 'spool' migration
-          scheme) and then migrate the backup to tape.
-
-          There is still the problem of getting the attributes committed.
-          If it takes a very long time to do, with the current code, the
-          job has not terminated, and the File daemon is not freed up.  The
-          Storage daemon should release the File daemon as soon as all the
-          file data and all the attributes have been sent to it (the SD).
-          Currently the SD waits until everything is on tape and all the
-          attributes are transmitted to the Director before signaling
-          completion to the FD. I don't think I would have any problem
-          changing this.  The reason is that even if the FD reports back to
-          the Dir that all is OK, the job will not terminate until the SD
-          has done the same thing -- so in a way keeping the SD-FD link
-          open to the very end is not really very productive ...

-  Date:   21 November 2005
-  Status:
-
-  What:   CACHDIR.TAG is a proposal for identifying directories which
-          should be ignored for archiving/backup.  It works by ignoring
-          directory trees which have a file named CACHEDIR.TAG with a
-          specific content.  See
-          http://www.brynosaurus.com/cachedir/spec.html
-          for details.
-
-          From Peter Eriksson:
-          I suggest that if this is implemented (I've also asked for this
-          feature some year ago) that it is made compatible with Legato
-          Networkers ".nsr" files where you can specify a lot of options on
-          how to handle files/directories (including denying further
-          parsing of .nsr files lower down into the directory trees).  A
-          PDF version of the .nsr man page can be viewed at:
-
-          http://www.ifm.liu.se/~peter/nsr.pdf
-
-  Why:    It's a nice alternative to "exclude" patterns for directories
-          which don't have regular pathnames.  Also, it allows users to
-          control backup for themselves.  Implementation should be pretty
-          simple.  GNU tar >= 1.14 or so supports it, too.

-  Origin: Phil Stracchino <phil.stracchino at speakeasy dot net>
-  Status: 
-
-  What:   Some time ago, there was a discussion of RunAfterJob and
-          ClientRunAfterJob, and the fact that they do not run after failed
-          jobs.  At the time, there was a suggestion to add a
-          RunAfterFailedJob directive (and, presumably, a matching
-          ClientRunAfterFailedJob directive), but to my knowledge these
-          were never implemented.
-
-          An alternate way of approaching the problem has just occurred to
-          me.  Suppose the RunBeforeJob and RunAfterJob directives were
-          expanded in a manner something like this example:
-
-          RunBeforeJob {
-              Command = "/opt/bacula/etc/checkhost %c"
-              RunsOnClient = No
-              RunsAtJobLevels = All       # All, Full, Diff, Inc
-              AbortJobOnError = Yes
-          }
-          RunBeforeJob {
-              Command = c:/bacula/systemstate.bat
-              RunsOnClient = yes
-              RunsAtJobLevels = All       # All, Full, Diff, Inc
-              AbortJobOnError = No
-          }
-
-          RunAfterJob {
-              Command = c:/bacula/deletestatefile.bat
-              RunsOnClient = Yes
-              RunsAtJobLevels = All       # All, Full, Diff, Inc
-              RunsOnSuccess = Yes
-              RunsOnFailure = Yes
-          }
-          RunAfterJob {
-              Command = c:/bacula/somethingelse.bat
-              RunsOnClient = Yes
-              RunsAtJobLevels = All
-              RunsOnSuccess = No
-              RunsOnFailure = Yes
-          }
-          RunAfterJob {
-              Command = "/opt/bacula/etc/checkhost -v %c"
-              RunsOnClient = No
-              RunsAtJobLevels = All
-              RunsOnSuccess = No
-              RunsOnFailure = Yes
-          }
-
-
-  Why:    It would be a significant change to the structure of the
-          directives, but allows for a lot more flexibility, including
-          RunAfter commands that will run regardless of whether the job
-          succeeds, or RunBefore tasks that still allow the job to run even
-          if that specific RunBefore fails.
-
-  Notes:  By Kern: I would prefer to have a single new Resource called
-          RunScript. More notes from Phil:
-
-            RunBeforeJob = yes|no
-            RunAfterJob = yes|no
-            RunsAtJobLevels = All|Full|Diff|Inc
-
-          The AbortJobOnError, RunsOnSuccess and RunsOnFailure directives
-          could be optional, and possibly RunsWhen as well.
-
-          AbortJobOnError would be ignored unless RunsWhen was set to Before
-          (or RunsBefore Job set to Yes), and would default to Yes if
-          omitted.  If AbortJobOnError was set to No, failure of the script
-          would still generate a warning.
-
-          RunsOnSuccess would be ignored unless RunsWhen was set to After
-          (or RunsBeforeJob set to No), and default to Yes.
-
-          RunsOnFailure would be ignored unless RunsWhen was set to After,
-          and default to No.
-
-          Allow having the before/after status on the script command
-          line so that the same script can be used both before/after.

+Item 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

+ Item n: List inChanger flag when doing restore.
+ Origin: Jesper Krogh<jesper@krogh.cc>

+
+   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.

+  What:   Enable the storage daemon to store backup data on Amazon's

+
+  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

+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
+
+  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.
+
+  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.

-   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.
+  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)
 
-  Why:    This would allow users more control over their Volumes and
-          prevent disk based volumes from consuming too much space.
+          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.
 
-  Notes:  The following two directives might do the trick:
+  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.
 
-          Volume Data Retention = <time period>
-          Remove Volume After = <time period>
+  Notes:  ./.
 
-          The migration project should also remove a Volume that is

+   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 24:  Accurate restoration of renamed/deleted files from
-          Incremental/Differential backups
-  Date:   28 November 2005
-  Origin: Martin Simmons (martin at lispworks dot com)
+   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.

+  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
+          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
+          Volumes" in an other thread:
+          http://article.gmane.org/gmane.comp.sysutils.backup.bacula.devel/11876/
+
+          In addition I'm not sure if this would be the same as respecting the
+          drive's "Maximum Concurrent Jobs" setting.
+
+          Example:
+
+          Storage {
+            Name = Neo4100
+            Address = ....
+            SDPort = 9103
+            Password = "wiped"
+            Device = Neo4100
+            Media Type = LTO4
+            Autochanger = yes
+            Maximum Concurrent Jobs = 3
+          }
+          
+          Storage {
+            Name = Neo4100-LTO4-D1
+            Address = ....
+            SDPort = 9103
+            Password = "wiped"
+            Device = ULTRIUM-TD4-D1
+            Media Type = LTO4
+            Maximum Concurrent Jobs = 1
+          }
+          
+          [2 more drives] 
+

+   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.

   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:  Item 14 (Merging of multiple backups into a single one) seems to
-          rely on this working, otherwise the merged backups will not be
-          truely equivalent to a Full backup.  
-
-          Kern: notes shortened. This can be done without the need for 
-          inodes. It is essentially the same as the current Verify job,

+          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:   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. 
+  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 h2:  Implement support for stacking arbitrary stream filters, sinks.
+Date:     23 November 2006
+Origin:   Landon Fuller <landonf@threerings.net>
+Status:   Planning. Assigned to landonf.
+
+  What:   Implement support for the following:
+          - Stacking arbitrary stream filters (eg, encryption, compression,  
+            sparse data handling))
+          - Attaching file sinks to terminate stream filters (ie, write out  
+            the resultant data to a file)
+          - Refactor the restoration state machine accordingly
+
+   Why: The existing stream implementation suffers from the following: - All
+           state (compression, encryption, stream restoration), is
+             global across the entire restore process, for all streams. There are  
+             multiple entry and exit points in the restoration state machine, and  
+             thus multiple places where state must be allocated, deallocated,  
+             initialized, or reinitialized. This results in exceptional complexity  
+             for the author of a stream filter.
+           - The developer must enumerate all possible combinations of filters  
+             and stream types (ie, win32 data with encryption, without encryption,  
+             with encryption AND compression, etc).
+
+  Notes: This feature request only covers implementing the stream filters/
+          sinks, and refactoring the file daemon's restoration
+          implementation accordingly.  If I have extra time, I will also
+          rewrite the backup implementation.  My intent in implementing the
+          restoration first is to solve pressing bugs in the restoration
+          handling, and to ensure that the new restore implementation
+          handles existing backups correctly.
+
+          I do not plan on changing the network or tape data structures to  
+          support defining arbitrary stream filters, but supporting that  
+          functionality is the ultimate goal.
+
+          Assistance with either code or testing would be fantastic.
+
+  Notes:  Kern: this project has a lot of merit, and we need to do it, but
+          it is really an issue for developers rather than a new feature
+          for users, so I have removed it from the voting list, but kept it
+          here, but at some point, it will be implemented.

+Item h3:  Filesystem watch triggered backup.
+  Date:   31 August 2006
+  Origin: Jesper Krogh <jesper@krogh.cc>
+  Status: 
+
+  What:   With inotify and similar filesystem triggeret notification
+          systems is it possible to have the file-daemon to monitor
+          filesystem changes and initiate backup.
+
+  Why:    There are 2 situations where this is nice to have.
+          1) It is possible to get a much finer-grained backup than
+             the fixed schedules used now.. A file created and deleted
+             a few hours later, can automatically be caught.
+
+          2) The introduced load on the system will probably be
+             distributed more even on the system.
+
+  Notes:  This can be combined with configration that specifies
+          something like: "at most every 15 minutes or when changes
+          consumed XX MB".
+
+Kern Notes: I would rather see this implemented by an external program
+          that monitors the Filesystem changes, then uses the console
+
+
+Item h4:  Directive/mode to backup only file changes, not entire file
+  Date:   11 November 2005
+  Origin: Joshua Kugler <joshua dot kugler at uaf dot edu>
+          Marek Bajon <mbajon at bimsplus dot com dot pl>
+  Status: 
+
+  What:   Currently when a file changes, the entire file will be backed up in
+          the next incremental or full backup.  To save space on the tapes
+          it would be nice to have a mode whereby only the changes to the
+          file would be backed up when it is changed.
+
+  Why:    This would save lots of space when backing up large files such as 
+          logs, mbox files, Outlook PST files and the like.
+
+  Notes:  This would require the usage of disk-based volumes as comparing 
+          files would not be feasible using a tape drive.
+
+  Notes:  Kern: I don't know how to implement this. Put on hold until someone
+          provides a detailed implementation plan.
+
+
+Item h5:  Implement multiple numeric backup levels as supported by dump
+Date:     3 April 2006
+Origin:   Daniel Rich <drich@employees.org>
+Status:
+What: Dump allows specification of backup levels numerically instead of just
+          "full", "incr", and "diff".  In this system, at any given level,
+          all files are backed up that were were modified since the last
+          backup of a higher level (with 0 being the highest and 9 being the
+          lowest).  A level 0 is therefore equivalent to a full, level 9 an
+          incremental, and the levels 1 through 8 are varying levels of
+          differentials.  For bacula's sake, these could be represented as
+          "full", "incr", and "diff1", "diff2", etc.
+
+Why: Support of multiple backup levels would provide for more advanced
+          backup rotation schemes such as "Towers of Hanoi".  This would
+          allow better flexibility in performing backups, and can lead to
+          shorter recover times.
+
+Notes:    Legato Networker supports a similar system with full, incr, and 1-9 as
+          levels.
+
+Notes:    Kern: I don't see the utility of this, and it would be a *huge* 
+          modification to existing code.
+
+Item h6:  Implement NDMP protocol support
+  Origin: Alan Davis
+  Date:   06 March 2007
+  Status: 
+
+  What:   Network Data Management Protocol is implemented by a number of
+          NAS filer vendors to enable backups using third-party
+          software.
+
+  Why:    This would allow NAS filer backups in Bacula without incurring
+          the overhead of NFS or SBM/CIFS.
+
+  Notes:  Further information is available:
+          http://www.ndmp.org
+          http://www.ndmp.org/wp/wp.shtml
+          http://www.traakan.com/ndmjob/index.html
+
+          There are currently no viable open-source NDMP
+          implementations.  There is a reference SDK and example
+          app available from ndmp.org but it has problems
+          compiling on recent Linux and Solaris OS'.  The ndmjob
+          reference implementation from Traakan is known to
+          compile on Solaris 10.
+
+  Notes:  Kern: I am not at all in favor of this until NDMP becomes
+          an Open Standard or until there are Open Source libraries
+          that interface to it.
+
+Item h7:  Commercial database support
+  Origin: Russell Howe <russell_howe dot wreckage dot org>
+  Date:   26 July 2006
+  Status:
+
+  What: It would be nice for the database backend to support more databases.
+          I'm thinking of SQL Server at the moment, but I guess Oracle, DB2,
+          MaxDB, etc are all candidates.  SQL Server would presumably be
+          implemented using FreeTDS or maybe an ODBC library?
+
+  Why: We only really have one database server, which is MS SQL Server 2000.
+          Maintaining a second one for the backup software (we grew out of
+          SQLite, which I liked, but which didn't work so well with our
+          database size).  We don't really have a machine with the resources
+          to run postgres, and would rather only maintain a single DBMS.
+          We're stuck with SQL Server because pretty much all the company's
+          custom applications (written by consultants) are locked into SQL
+          Server 2000.  I can imagine this scenario is fairly common, and it
+          would be nice to use the existing properly specced database server
+          for storing Bacula's catalog, rather than having to run a second
+          DBMS.
+
+  Notes: This might be nice, but someone other than me will probably need to
+          implement it, and at the moment, proprietary code cannot legally
+          be mixed with Bacula GPLed code.  This would be possible only
+          providing the vendors provide GPLed (or OpenSource) interface
+          code.

+   Status: Blue sky
+
+   What: XACML is "eXtensible Access Control Markup Language" and "SAML is
+          the "Security Assertion Markup Language"--an XML standard for
+          making statements about identity and authorization.  Having these
+          would give us a framework to approach ACLs in a generic manner,
+          and in a way flexible enough to support the four major sorts of
+          ACLs I see as a concern to Bacula at this point, as well as
+          (probably) to deal with new sorts of ACLs that may appear in the
+          future.
+
+   Why: Bacula is beginning to need to back up systems with ACLs that do not
+          map cleanly onto traditional Unix permissions.  I see four sets of
+          ACLs--in general, mutually incompatible with one another--that
+          we're going to need to deal with.  These are: NTFS ACLs, POSIX
+          ACLs, NFSv4 ACLS, and AFS ACLS. (Some may question the relevance
+          of AFS; AFS is one of Sine Nomine's core consulting businesses,
+          and having a reputable file-level backup and restore technology
+          for it (as Tivoli is probably going to drop AFS support soon since
+          IBM no longer supports AFS) would be of huge benefit to our
+          customers; we'd most likely create the AFS support at Sine Nomine
+          for inclusion into the Bacula (and perhaps some changes to the
+          OpenAFS volserver) core code.)
+
+          Now, obviously, Bacula already handles NTFS just fine.  However, I
+          think there's a lot of value in implementing a generic ACL model,
+          so that it's easy to support whatever particular instances of ACLs
+          come down the pike: POSIX ACLS (think SELinux) and NFSv4 are the
+          obvious things arriving in the Linux world in a big way in the
+          near future.  XACML, although overcomplicated for our needs,
+          provides this framework, and we should be able to leverage other
+          people's implementations to minimize the amount of work *we* have
+          to do to get a generic ACL framework.  Basically, the costs of
+          implementation are high, but they're largely both external to
+          Bacula and already sunk.
+
+   Notes: As you indicate this is a bit of "blue sky" or in other words,
+          at the moment, it is a bit esoteric to consider for Bacula.

+Item h9:  Archive data

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

+Item h10: Clustered file-daemons
+  Origin: Alan Brown ajb2 at mssl dot ucl dot ac dot uk
+  Date:   24 July 2006
+  Status:
+  What:   A "virtual" filedaemon, which is actually a cluster of real ones.
+
+  Why:    In the case of clustered filesystems (SAN setups, GFS, or OCFS2, etc)
+          multiple machines may have access to the same set of filesystems
+
+          For performance reasons, one may wish to initate backups from
+          several of these machines simultaneously, instead of just using
+          one backup source for the common clustered filesystem.
+
+          For obvious reasons, normally backups of $A-FD/$PATH and
+          B-FD/$PATH are treated as different backup sets. In this case
+          they are the same communal set.
+
+          Likewise when restoring, it would be easier to just specify
+          one of the cluster machines and let bacula decide which to use.
+
+          This can be faked to some extent using DNS round robin entries
+          and a virtual IP address, however it means "status client" will
+          always give bogus answers. Additionally there is no way of
+          spreading the load evenly among the servers.
+
+          What is required is something similar to the storage daemon
+          autochanger directives, so that Bacula can keep track of
+          operating backups/restores and direct new jobs to a "free"
+          client.
+
+   Notes: Kern: I don't understand the request enough to be able to
+          implement it. A lot more design detail should be presented
+          before voting on this project.
