Abstract:
A request is received to clone a source data object. A source block range of the source data object in a source logical storage unit is determined. An empty data object in the destination logical storage unit is created. A destination block range of the empty data object in the destination logical storage unit is determined. The source block range is mapped to the destination block range. The source data object is cloned based on the mapping.
