Abstract
Systems, devices and methods are described for copying used data block within a source volume to a target volume. A copy manager is provided on a host system for coordinating external copy requests originating from external sources. An application adapter layer is provided that provides lists of the blocks that are occupied on the source volume by the specific applications. The occupied block lists is forwarded along with the copy requests to a storage system adapter layer. The storage system copies only the data that are written in the occupied blocks of the source volume to the target volume. During the copy operation, all I/O requests are paused and resumed after the copy operation is complete.
