You could also use something like TrueCrypt ( http://www.truecrypt.org/ ). Truecrypt can encrypt an entire volume/partition or, it can create a virtual volume in a file. It should be possible to create a pre-backup shell script that connects to the remote machine with ssh and mounts the TrueCrypt volume. A post-backup script could then unmount the remote volume. It would not be bullet-proof but, the data would be encrypted when the backup was not running. Another possibility would be to remotely mount a volume hosting a TrueCrypt file (using FTPS, WebDAV, or whatever), then mount the TrueCrypt volume locally. That way, the data would never be unencrypted on the remote server. I don't know if that would work with the hard linking or, if there would be other complications. I haven't tried it over a WAN connection (yet). That is definitely possible over a fast LAN connection. If you are just looking to do this with a USB-connected drive, it would almost certainly work.
