Yet another choice that is especially good if you have more than one
machine to back up and/or the data changes and you need to do the
backups regularly: http://backuppc.sourceforge.net/
Run backuppc on a different machine, letting it run automatically
over the network.  It won't automatically make a machine
bootable, but if you learn just a bit about partitioning,
formatting, and grub you can do that part yourself.
