Abstract
A backup is completed within a backup window designated by a user. When copying data in a first storage area, which is a backup target, to a second storage area, the capacity of a medium serving as a third storage area which is sufficient to complete a backup within the backup window, is calculated based on information about a differential bitmap describing an area in the second storage area to which the relevant data is copied from the first storage area, configuration information about a storage system where the storage areas are stored, and performance information about media constituting the storage areas; and differential data is copied using the second storage area and the third storage area; and the data written to the third storage area is copied to the second storage area.
