Abstract
The present invention provides a backup method for a storage control device that instructs a storage device to split a primary volume and a copy volume in the storage device, and to execute a backup operation from the copy volume to a backup volume. The storage device includes the backup volume for the copy volume. The backup method includes: the storage control device allocating a specified number of generations of the backup volume in the storage device for the copy volume; instructing the storage device to split the pair; executing a virus check on the copy volume; copying contents of the copy volume to the backup volume as a most recent generation backup if no virus is detected; updating generations in the backup volume for generations prior to the most recent generation; and instructing the storage device to re-link the split pair.
