Abstract
A method and apparatus for backing up a storage system, e.g., one or more disk drives. In one embodiment, an apparatus utilizes a volume snapshot service (VSS) to create a snapshot image file of a computer's storage system and then subsequently reads the data blocks contained in the snapshot image file. A determination of the number of modified data blocks, i.e., the data blocks that have changed since a last backup operation, is made. The apparatus estimates a backup size from the number of modified data blocks and subsequently determines if the estimated backup size exceeds a predetermined threshold. In the event the predetermined threshold is exceeded, a backup operation is conducted.
