摘要: An improved method and apparatus for quickly efficiently updating the original source volume target volumes after has become temporarily unavailable. The is characterized as a while Transfer lists of different data blocks are generated. Data not originally found on copied to target. included that were removed. By focusing upon specific blocks, this technique avoids use filer overhead other computational resources would be expended if entire recopied.
