Abstract
A data storing system including: a first, second and third storage systems providing first, second and third logical volumes; wherein the first logical volume and the second logical volume forms a first replication pair which indicates the first logical volume is a replication source and the second logical volume is a replication destination, and the second logical volume and the third logical volume forms a second copy pair which indicates the second logical volume is the replication source and the third logical volume is the replication destination. The replication pairs may adopt differing possible pair statuses, which may affect consistency between such pairs.
