This may or may not be relevant... I am testing an older version of Bacula at a client, and I don't think it has the script hooks that allow the automatic mounting and unmounting of USB (or other removable) disks. Also, they are currently using Amanda so Bacula is only backing up a very small amount of data for testing purposes, so I never wanted to be in the position where Amanda tries to mount or unmount the disk when Bacula was using it, or visa versa.
The solution I decided on was to use autofs. I have this in auto.master: /vol /etc/auto.vol --timeout=3 And this in auto.vol: backup -fstype=auto,rw,sync :/dev/sda1 The current limitation is that the device has to be /dev/sda1, but unless the system has gotten itself confused, the USB drive is always /dev/sda1 so I haven't found it a problem yet. This setup means that as soon as /vol/backup is accessed, the drive mounts, and as soon as there has been no access for 3 seconds (--timeout=3 in auto.master), it unmounts again. It saves mucking around with scripts in either Bacula or Amanda, and means that if someone does a restore, there is no chance of them forgetting to umount the drive, which was previously causing all sorts of problems.
