Specifically, provided is a computer system, and its management method, including multiple nodes for providing to a host system a storage area to be used for reading and writing data, and respectively acquiring a snapshot at a pre-set time, and which configures a node group from a part or all of the nodes among the multiple nodes and makes data redundant in node units in the node group. With the foregoing computer system and its management method, an access log is acquired from the respective nodes configuring the node group, and the usage of the snapshot in the node group is determined based on the acquired access log of the respective nodes, and the acquisition time of the snapshot is changed in a part or all of the nodes among the nodes configuring the node group based on the determination result.
