Then you'll probably need to encrypt the data on the drive, since otherwise anybody could just take the drive, plug to their laptop and start looking inside (and if it wasn't FAT-filesystem, it still wouldn't be difficult to lurk the information unless it was encrypted).

So, form your question like this: which encryption software to use, and how?

I've not actually tried it myself, but I've heard that truecrypt is good. It's free, open source, and cross platform. The Security Now podcast had an episode which featured it.

Is there a bank near your office? One that rents safe-deposit boxes? Ooh, and with a Starbucks Coffee nearby? Problem solved!

Don't fool around with encryption on backup media. Secure the media itself.

I use "tar" to create a tarball and then I use gpg(gnupg) to encrypt the tarball. Then I write the encrypted tarball to a DVD+RW. The gpg keys can be exported and then imported to another machines gpg or pgp keys. There should be "tar" software available for Windows and "tar" comes with all Linux's and BSD's.

Mmmhhh unfortunatly
Truecrypt is not completly free, see this
http://lists.debian.org/debian-legal.../msg00295.html

I am using luks which is the future standard for media encryption
http://www.saout.de/tikiwiki/tiki-in...eviceUsingLUKS
You will find plenty of documentation on the net.
I don't use windows but there exist a tool to read luks format.
