Abstract
A data-duplication control apparatus that controls a duplication process for duplicating data stored in a storage device that constitutes redundant-array-of-independent-disks includes an information storing unit that stores information on a type of the redundant-array-of-independent-disks of the storage device; and a duplication-source-device selecting unit that selects a storage device of a duplication source based on the information stored.
Claims18
A data-duplication control apparatus that controls a duplication process for duplicating data stored in a storage device that constitutes redundant-array-of-independent-disks, the data-duplication control apparatus comprising:
- an information storing unit that stores information on a type of the redundant-array-of-independent-disks of the storage device;
- and
- a duplication-source-device selecting unit that selects a storage device of a duplication source based on the information stored.
A data-duplication control method of controlling a duplication process for duplicating data stored in a storage device that constitutes redundant-array-of-independent-disks, the data-duplication control method comprising:
- storing information on a type of the redundant-array-of-independent-disks of the storage device;
- and
- selecting a storage device of a duplication source based on the information stored.
A computer-readable recording medium that stores a data-duplication control program for controlling a duplication process for duplicating data stored in a storage device that constitutes redundant-array-of-independent-disks, wherein the data-duplication control program makes a computer execute
- storing information on a type of the redundant-array-of-independent-disks of the storage device;
- and
- selecting a storage device of a duplication source based on the information stored.
