A first journal group including a primary volume and a first journal volume and a second journal group including a secondary volume and a second journal volume are set in a consistency holding group. Journal processing is performed while ensuring consistency of replication between the first journal group and the second journal group. The second journal group is arranged for each node in which the secondary volume of the consistency holding group is arranged. The secondary volume is arranged in each node in the second storage system based on a usage status of a resource of each node in the second storage system and the number of nodes in which the secondary volume in the consistency holding group is arranged.
