Rsync Server

From Bibliotheca Anonoma

If you transmit a large amount of data from the server to your computer often, you may notice some SSH disconnects from time to time. This is a result of the natural instability of the internet.

Obviously, that sort of SSH disconnect is not acceptable when pushing tons of data for backup across the internet. So if you're trying to sync data (such as a backup) with a server, use a raw rsync server itself with TCP/UDP.
