    Abstract: An efficient disaster recovery system is constructed at three data centers. A data center includes: a business server for executing an application in response to an input/output request; a storage system for providing a first storage area storing data in response to a request from the business server; and a management server for managing a second data center or a third data center among the plurality of data centers as a failover location when a system of a first data center having the first storage area stops; and wherein the management server: copies all pieces of data stored in the first storage area to a second storage area managed by a storage system of the second data center; and copies part of the data stored in the first storage area to a third storage area managed by a storage system of the third data center.
