If you are in a situation where you don't control the second server (like a
web server run by someone else), you can also use sitecopy, which allows you
to push it out to someone who is just running ftp.

If you're into failing over to a second server when the first one goes down,
then you might look at linux-ha.org.  If you are into bleeding-edge
mirroring, you might look at drbd which is pointed to by that site.
