Patent abstract
A computer-implemented method and system for improving efficiency in a delta compression process selects a data chunk to delta compress and generates a sketch for the selected data chunk. A set of candidate data chunks with a matching sketch is searched for. The set of candidate data chunks with at least a minimum degree of similarity is ranked by location status data. Tie-breaking of the set of candidate data chunks is done using a degree of sketch similarity for each candidate and the selected data chunk is delta compressed with a selected candidate data chunk.
