Full complete MySQL database replication? Ideas? What do people do?

Question

Currently I have two Linux servers running MySQL, one sitting on a rack right next to me under a 10 Mbit/s upload pipe (main server) and another some couple of miles away on

Answer 1

GoldenGate is a very good solution, but probably as expensive as the MySQL replicator.

It basically tails the journal, and applies changes based on what's committed. They support bi-directional replication (a hard task), and replication between heterogenous systems.

Since they work by processing the journal file, they can do large-scale distributed replication without affecting performance on the source machine(s).
