Dear Lazyweb, Need Simple Encrypted Backup Method to USB on Linux

Ok, the title pretty much says it all. Lu bought me a new 250 gb backup drive for locking down my backups while on the road (and I already have a halfway solution at home thanks to advice from readers). I’m curious what is the best option for syncing up my 80 gb thinkpad x61 to a partition on this drive, which can act as a daily backup, and be used in the event of something bad? I run gentoo on my computers currently, and want to just do more than just rsync to this drive in that I want the content encrypted.

Please help me lazyweb! Another option is to pay for a service like mozy.com or carbonite, but I want to stay in commandline realm and where I don’t need network access..
