PROBLEM TO BE SOLVED: To immediately advance processing by a standby system when a failure occurs in a normal system. SOLUTION: When a request of writing data occurs, a storage 301 of an operation system transmits data of a writing object and a delay writing request to a storage 302 of a standby system. Also, the storage 301 transmits a delay writing execution request to the storage 302, upon receiving a resumable point notification from a host 300. The storage 302 stores the received data in a temporary memory means on demand of delay writing, and also stores the data stored in the temporary memory means in a storage medium, upon receiving the delay writing execution request.
