Thanks John for that news.
I will give it a try in the next two weeks (opensuse 11.1/11.0)
It just arrived at the good time to my new externals month backup :-)
It is easy to include the detection off the drive with crypto_luks fs as
all data leaving the office need to be encrypted.
If this could also work, it would be a nice extension to bacula capabilities.
