Bacula Projects Roadmap
- Status updated 18 August 2007
- After removing items completed in version
- 2.2.0 and renumbering
+ Status updated 19 March 2008
Items Completed:
implement it. A lot more design detail should be presented
before voting on this project.
+========= Added since the last vote =================
+
+Item: Store and restore extended attributes, especially selinux file contexts
+ 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.

+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.
+
+
+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!
