Abstract
While in active state, a first storage apparatus including first and second storage areas copies data stored in the first storage area to the second storage area, copies data stored in the first storage area to a third storage area so that data is synchronized between the first and third storage areas, and copies data stored in the second storage area to a fourth storage area so that data is synchronized between the second and fourth storage areas. When a second storage apparatus including the third and fourth storage areas has transitioned from standby to active state and thereby gets to receive access to the third storage area, instead of to the first storage area, from an external information processing apparatus, the second storage apparatus copies data stored in the third storage area to the fourth storage area, based on setting information stored in a storage unit.
