I have three disks available for backups.   They are 465GB 698GB and 232GB.   I want the backups to use the 450 and 650 as much as they like but only use 150GB of the third drive (This is the one with the BareOS and Linux installed)  I have multiple pools as each pool has a different retention time frame.

Is this possible?   Is it better to make one storage device containing both of the large HDD and forget about the space on the / (root) disk?   If there are two HDD in a device .conf will bareos use each of them as required or do I need to specify how to utilize each drive?

Greg

P.S.
  Think this is the last issue I have before I post all my finding on setting up bareos from scratch.

It depends on the usage.

You might create separate devices and use them in separate pools.

Or you might create a single directory, pre-label specific number of volumes of fixed size ("virtual tapes") and symlink them to a single directory so you have a single pool (haven't tried it myself but my intuition is that it should work).

Or you might use vchanger to crawl with its virtual autochanger across three separate directories (and also create fixed-size files).

There are several possibilities.

(I have a vchanger based setup across several disks I plug selectively into a USB dock)
