摘要

PPROBLEM TO BE SOLVED: To provide a technique for performing a file system reproduction system by utilizing the advantage of the reproduction system of a block level. PSOLUTION: In this program, a source site uses a source server and a source storage system, and a target site uses a target server and a target storage system. The source server operates data stored in the source logical unit of the source storage system. The target server prepares the flash copy of a replica volume, and in response to the reception of the first replica volume being the reproduction of the storage volume from the source storage system by the target storage system, the target server performs the restoration of the flash copy of the replica volume. The target server exports the data of the restored flash copy of the replica volume. Thus, the restored flash copy of the replica volume is made available for the client. PCOPYRIGHT: (C)2007,JPO&INPIT
