Abstract
Exemplary methods, apparatuses, and systems transmit a request to a destination site for information indicating whether or not each of a plurality of regions of a destination logical storage device is allocated. Each of the corresponding regions of a source logical storage device is determined to be either allocated or unallocated. The allocation information is received from the destination site. The allocation status of a first region of the plurality of regions of the source logical storage device and of a corresponding first region of the plurality of regions of the destination logical storage device is determined. The first region of the source logical storage device and the corresponding first region of the destination logical storage device are synchronized based upon the determined allocation status of the first region of the source logical storage device and determined allocation status of the corresponding first region of the destination logical storage.
