Abstract
A system and method are disclosed for efficiently copy a disk image between storage devices. In accordance with one example, a computer system issues a request to create on a first storage device a snapshot of a first disk image that is stored on the first storage device. The computer system then issues a request to create on the first storage device a second disk image based on the snapshot, and copies the snapshot on to a second storage device. The computer system issues a request to create on the second storage device a third disk image based on the snapshot. The computer system then issues a request to compute a difference between the second disk image and the snapshot, and the difference is overwritten on to the third disk image.
