No problems there, I think. > I see the following problem. Each instance of bacula has its own database > about pools and media.

You let Bacula handle all the volumes, simply and the catalog will have data about all media, the ones available and the ones not available currently. > I see two approaches: > > 1.

Rather simple, and that's what i'd do with 1.38 and below: Set all volumes of state "Used", "Recycled", "Purged" or "Append" in the catalog to a state of "Disabled" when removing a disk. Keep the old volume state on that disk. When re-connecting such a disk, undo these changes. Should be possible to do this by script, triggered by plugging in th disk, managed by HAL or udev or whatever you use. > 2. Just configure bacula to have its database on the USB disk, too.

That might work, but you will never have information about backups on the other media.

AFAIK there's improved support for removable hard disks implemented - just what you need. You'll have to read the ReleaseNotes and the manual carefully, because the upgrade process itself requires a catalog upgrade (easily done, usually) and the new functions are yet unknown to me.
