There is some good info at http://linux-ha.org/.  You can run drbd or
software raid1 over enbd to keep the contents in sync and a heartbeat
based IP failover to switch, but there are a lot of details to get
right.  Periodically rsync'ing to the backup server would be safer
but not quite a real-time copy.
