Abstract
Method and apparatus for restoring copies of a logical object to a primary computer storage device are disclosed. A copy of the logical object is provided, physical blocks of memory in the primary storage device are allocated, a map of the data blocks will be copied to the physical blocks of the primary storage devices created. The copying may then occur using the created map. The copy of the logical object may be an abstract bloc set, which includes data blocks of the logical object potentially out of order and metadata identifying relative position of the data blocks.
