You should be able to setup your server to create the backups, and FTP those to your computer. But you will need to setup your computer to allow your computer to accept connections only from the server.
I guess I was a little vague.. I would like to image the base install once secured. Then I can create the backup routines for the "users" and have them stored else where. maybe I just don't know what the heck I want to do
Wouldn't saving the base secure config seperate save on bandwidth while doing just user backups?
