-Item 5: Deletion of disk Volumes when pruned
- Date: Nov 25, 2005
- Origin: Ross Boylan <RossBoylan at stanfordalumni dot org> (edited
- by Kern)
- Status: Truncate operation implemented in 3.1.4
-
- What: Provide a way for Bacula to automatically remove Volumes
- from the filesystem, or optionally to truncate them.
- Obviously, the Volume must be pruned prior removal.
-
- Why: This would allow users more control over their Volumes and
- prevent disk based volumes from consuming too much space.
-
- Notes: The following two directives might do the trick:
-
- Volume Data Retention = <time period>
- Remove Volume After = <time period>
-
- The migration project should also remove a Volume that is
- migrated. This might also work for tape Volumes.
-
- Notes: (Kern). The data fields to control this have been added
- to the new 3.0.0 database table structure.

-Item 6: Implement Base jobs
- Date: 28 October 2005
- Origin: Kern
- Status:
-
- What: A base job is sort of like a Full save except that you
- will want the FileSet to contain only files that are
- unlikely to change in the future (i.e. a snapshot of
- most of your system after installing it). After the
- base job has been run, when you are doing a Full save,
- you specify one or more Base jobs to be used. All
- files that have been backed up in the Base job/jobs but
- not modified will then be excluded from the backup.
- During a restore, the Base jobs will be automatically
- pulled in where necessary.
-
- Why: This is something none of the competition does, as far as
- we know (except perhaps BackupPC, which is a Perl program that
- saves to disk only). It is big win for the user, it
- makes Bacula stand out as offering a unique
- optimization that immediately saves time and money.
- Basically, imagine that you have 100 nearly identical
- Windows or Linux machine containing the OS and user
- files. Now for the OS part, a Base job will be backed
- up once, and rather than making 100 copies of the OS,
- there will be only one. If one or more of the systems
- have some files updated, no problem, they will be
- automatically restored.
-
- Notes: Huge savings in tape usage even for a single machine.
- Will require more resources because the DIR must send
- FD a list of files/attribs, and the FD must search the
- list and compare it for each file to be saved.
-
-
-Item 7: Add ability to Verify any specified Job.
