Hi Steven... I believe that you can accomplish what you are looking for using
Bacula's "Copy Jobs", Josh Fisher's excellent "vchanger" add-on, and a little
hard work. :)


Obviously it is more complicated than the four or five steps listed below, but
here is the basic concept and process:

You can take the 40GB local storage and create several small(ish) (5GB?)
Bacula "file volumes." (40GB seems VERY small to me)

These file volumes would be added into a pool called something like
"DailyLocal" with a short retention period (~1 week?) so that they will be
available during the next week's run (are you sure it's not 400GB? :)  in
which case the retention period can be set higher. :)

Create your daily backup job to write to the file volumes in the DailyLocal
pool on the local storage

Configure Bacula for off-site backups with auto-mounting, removable backups
and full volume encryption: http://www.revpol.com/node/140

Create a Copy job that will run once/week and copy the week's jobs to the
removable drives (see section 24.1 of Bacula's "main.pdf" file)

Those are the steps. If you run into any specific problems along the way, you
can just ask here, or join some of us in the #bacula channel on freenode.net

Hope this helps!
