I would use either Acronis or dd to create an image of the fully installed system one time. Then I would use rsync within a cron job to have actual backups. In an emergancy you can recreate your system with Acronis or dd and then copy the incremental changes back with rsync.
If you like, you can do the initial backup with Acronis or dd periodicaly every 3 or 6 or 12 month for examples. 73 de Reiner, dh9fax
