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.
It depends on the emergency…
For live data, replication is the way to go, but an accidental
DROPwill be replicated straight across…Also, are you looking to survive a building disaster, or just a server/drive/hardware crash?
