ABSTRACT:
A storage apparatus system comprises first and second data storage systems. The first data storage systems can copy an image of data stored therein to the second data storage system without affecting access to storage in the first data storage system. In addition, failover processing is provided between the first and second data storage systems, wherein the second data storage system serves as the failover system.
