I've used rsync in the past, but I only used it to:

create a local backup
grab files from a remote rsync server for a mirror.
updated a remote server over SSH.

In this tutorial, I am going to show you how you can set up your server to accept rsync connections with a separate user/authentication list to your computer's local user accounts. This is more like samba or FTP where your server accepts file transfers with login details that aren't local users.
