A storage apparatus configuration in a three data center architecture comprises first and second data storage systems, and a remote data storage system. The first data storage systems can copy an image of data stored therein to the remote data storage system without affecting access to storage in the first data storage system. The second data storage system is configured to perform a takeover operation if the first data storage system becomes unavailable.
