From what you've just written, it sounds like I'm already doing this. I have bacula configured to backup about five systems to file storage on a RAID array in the wee hours of every morning.

large RAID. Once a week, I wanted to copy the volumes from my full job
pool to tape for off-site storage. It sounds like Bacula is not quite
up to such a configuration yet.
The only disadvantage that I can see to this is that in order to restore a file from tape, I actually will have to run two restore jobs -- the first one from a tape to a file storage file & the second from file storage to a system. As Kern & Arno already have mentioned in earlier replies it is not possible, this way, to restore directly from tape.
Cheers!

That's an interesting way to handle things, and one that I hadn't thought of. Other than the general uncomfortable-ness of backing up my backups, I might just give that a shot.
For the moment though, I'm going to see if I can get the incrementals to file and fulls to tape scenario working. I just need to see about getting these bootstrap files set up correctly.
Thanks.
I'm doing something similar on my system. Full backup on the first Sunday of the month, Incremental Mon-Sat, Differential on remaining Sundays. Output is to a file specified in the Pool statements - all on a Raid-0 drive. Here is a sample of my pool statement:
# Server4 pool definition
Pool {
Name = Server4
Pool Type = Backup
Recycle = no Use Volume Once = yes
Maximum Volume Bytes = 650MB
AutoPrune = yes LabelFormat = "Backup-Server4-"
Volume Retention = 365 days Accept Any Volume = yes }
Note the 650MB volume limit and the Use Volume Once. I end up with a set of files in the Raid-0 partition that are marked with Volume Status Full that are no more than will fit on a CD-RW. Seven of these files will fit on a DVD+RW disk or a DVD+R disk. I'd thought to use CD/RW media, but what's the point? DVD+RW was only $1.40 per disk at Staples (Fuji brand) and I'm less likely to run out of space and have to use multiple media for incremental backups.
My full backups are copied from the Raid0 array to DVD+R and then erased from the Raid-0 drive. Incremental backups go to DVD+RW for the rest of the days (and are erased after copy). Differential dumps go to DVD+R disks.
This copy from Raid-0 to DVD is done by hand; I don't have any way to feed blank DVDs into a writer anyway. The DVD+RW disks get reused and the Full and Differential DVD+Rs get saved in another building.
The major limitation of this method is that the Raid-0 array has to be able to fit all the client backups onto it. Right now it's working for me.
