Abstract
Method and apparatus for generating partial backups of logical objects in a computer storage system are disclosed. Changed data blocks are identified and stored as differential abstract block sets. The differential abstract block set may include data blocks in any order and metadata identifying the relative position of the data block in the logical object. The invention includes methods for formatting updated backups using the differential backups.
