I have around 400 GB Live mysql Databases on one server and I like to create a mirror for this database. In the server I have database ranging from 1 GB to 100 GB. What are the best practices available that I can use? My purpose is that I should be able to switch in case of emergency. It should have all live data.
Thanks.

Replication in MySQL supports different types of synchronization. The original type of synchronization is one-way, asynchronous replication, in which one server acts as the source, while one or more other servers act as replicas.
It depends on the emergency...
For live data, replication is the way to go, but an accidental DROP will be replicated straight across...
Also, are you looking to survive a building disaster, or just a server/drive/hardware crash?
