That's interesting, since my system udev/autofs auto-mounts my encrypted drives as: /mnt/eSATA-1_Backups/<UUID> And my magazines are each defined in vchanger.conf as: magazine = "UUID:<UUID>" > The script I wrote was designed to be run via udev on a hot insert / > remove of drives.

See: http://revpol.com/offsitebackups I do udev/autofs auto-mounted encrypted drives so besides the encryption it seem like you are trying to do exactly what I have posted there. (note: there was a lot of udev and autofs development activity during and just after I wrote that so some things are not exact - for example some outputs, and some commands) > The other difference is that I set InChanger=(0|1) instead of disabling > the volume. In theory, this will cause bacula to send a "Need > intervention" email instead of failing (but I'm yet to try this). I think that was initially considered, but the Enabled field turned out to be the fool-proof method for us. Hope this helps!
