I'm using autofs, as well, but it (and bacula) doesn't do what I really
would like to do. Maybe you can help me?
Here is what I'd like to do:
- Backups on the 1st to the 15th of the month go to disk BACKUP1. A full
on the 1st, then only incrementals.
- Backups on the 16st to the 31th of the month go to disk BACKUP2. A
full on the 1st, then only incrementals.
This works very well with a schedule, as long as both disks are connected.
But I would like to be able to take the disk that isn't being used off
site. Since the schedule is rigid, I'm not sure how to handle the
situation when the "wrong" disk is plugged into the USB port.
