The connection used for replication will be 100Mbit/sec. I'd like to find a method that can get me as close to immediate replication as possible, however a lag of about 3 hours is probably acceptable for most of the content.
I've been looking at the file server extension to NDMPv4 and various third-party software, as well as things like rsync, but wondered if anyone else had any ideas of things I should be looking at?
Rsync is probably your best bet.
