I have an external drive which I used to do encrypted TM backups to, via a direct USB connection (i.e. the entire drive became encrypted - Lion).
I would like to switch to wireless backups but without allowing the data to become accessible to other people in my network.
I thought about attaching the encrypted drive to a Mac server on the network and to somehow back to there - the problem is how do I get the unlocking of the drive to occur only on my local machine? (I can't allow other users who log into that server to access the files on the drive if it were to be unlocked by the server)
