Disaster planning

I need to setup a Backup Server to allow quickly get up and running if there is a server problem.

Setup a 2nd Server in the Tree
Install Groupwise system

Backup Main Server to 2nd Server using DBCOPY

If there is a problem would I be able to simply add a secondary IP address (Main server IP)
and Start Groupwise on the 2nd Server

is this practical ?

I'm not sure the Dbcopy process copies config files for GW, Webaccess etc

are there any other files I need to copy or include in my daily backup ?

Ideally, I'd like to be able to fix the main server and go back to it

Would like to TEST this without messing up the live system or backup server!

GW 2012 + Webaccess + GWIA

Would appreciate any help / pointers
