摘要： Provided is a computer system, comprising a storage system and a management computer. The management computer manages differential copy start times, differential data amounts of first pairs, and a data amount that can be copied in differential copy per unit time; identifies one of the first pairs for which the differential copy is to be started and a start time of the differential copy; subtracts the data amount of differential copy per unit time that is allocated to the identified one of the first pairs from a differential data amount of the identified first pairs; add the unit time to the identified start time; judges that the differential copy has been finished at a time when the subtracted differential data amount reaches zero or less; and calculates time zones in which the first pairs execute differential copy based on the time at which differential copy has been finished.

摘要： A storage system allocates a data storage area in response to an access request from a first computer if the capacity of a first physical storage device configuring a first logical storage area, provided to the first computer, is equal to or lower than a predetermined threshold. The storage system associates the first logical storage area with another physical storage device, which is different from the first physical storage device associated with a second logical storage area provided to the first computer and a second computer, and allocates a data storage area from the another physical storage device if the capacity of the first physical storage device associated with the first logical storage area exceeds the predetermined threshold.

摘要： The load of managing a storage system is lessened. In a storage system where multiple logical volumes are included in a logical volume group and a copy of the logical volume group is made in a pool area different from the one to which the logical volume group belongs, a management computer adds to the pool area capacity when the capacity of a pool area exceeds a predetermined threshold. When the pool area includes multiple logical volume groups, the management computer requests the storage system to create a pool area for each of the logical volume groups and to create the logical volume groups respectively for the created pool areas. When the pool area includes one logical volume group, the management computer requests the storage system to make the capacity of the pool area coincide with the capacity of a pool area to which the logical volume group is copied.
