Abstract
A resource status value, which shows the resource status of a resource to be utilized in a remote copy that conforms to a copy mode configured for a copy unit created from a first data volume and a second data volume, is acquired either regularly or irregularly. A determination is made as to whether or not the acquired resource status value exceeds a prescribed threshold, and when it is determined that the acquired resource status value exceeds this prescribed threshold, either the resource to be used for a remote copy conforming to a configured copy mode is increased, or the configured copy mode is changed to a different copy mode.
