BACKUP Strategy for VirtualCenter Server:

Virtual Center is recommended to be on Physical Box, as a DR strategy you can created one VM and leave it powered off. Use it only when Primary fails. When Primary fails, Power On DR server, Point it to Virtual Center database. Have System Admins point to DR server till you bring back the Primary.
