摘要：
In the case in which data in a storage system A is remotely copied to a storage system B, it is not taken into account whether the data of the remote copy is WORM data. In the case in which a setting is made such that data stored in a volume in the storage system A is copied to a volume in the storage system B, storage system A judges whether an attribute to the effect that data can be referred to and can be updated or to the effect that data can be referred to but cannot be updated is added to the volume in the storage system A. Then, if the volume is a volume to which the attribute to the effect that data can be referred to but cannot be updated is added, such attribute is added to the volume in the storage system B.
