Data is written and read in System 1

Data is periodically replicated to System 2 via an Internet connection

In the event of a raid array error or disk drive error on System 1, the server will send an e-mail notification to the administrator,
In the event of a loss of system 1 users will be notified,Administrator then switches users to System 2 over the WAN.

After switching, replicated data is available on System 2
