I described creating an Encrypted USB Key Fob previously. Here is a script I use to backup my data to it. It rsyncs a few directories and will also download your calendar and contacts from Zimbra if you are so blessed.

Just put this script on the key in bin/backup. Put the key in each computer and cd to /mnt/disk/bin and run the script. If you are not prompted for the password when you insert the key run 'sudo /sbin/cryptsetup luksOpen /dev/sdb1 dm-usb'.

# Script to backup misc private and settings files to usb key.
# You might stick the key in each of your machines and
# run this script to backup your important or sentimental
# personal files.
#
# Be sure to encrypt the key first:

# Todo:
#   o Think more about what is useful to backup (.kde? .gnome?)
#     .kde has a whole lot of application data in it such as amarok podcasts...
