Backing up a remote computer using SD over AFP connection?

[dnanian]

Given the typical upload speed of a cable modem or DSL line, Erik, I think this would pretty much be unacceptably slow. Even Smart Update will take a long time, because AFP is not terribly bandwidth-efficient, so attempting to check every file over the network will likely take too much time.

In this kind of case, I think you need something that has a server on both sides, and is designed to do operations over very low bandwidth connections: something like rsync (or its derivatives) would likely provide the most acceptable result...
