Abstract
A technique for performing data reduction applies deduplication principles when performing data compression, providing a form of enhanced compression. The technique obtains a chunk of data that contains multiple extents and applies deduplication actions to identify duplicate extents within the chunk. The technique marks duplicate extents in metadata. Such duplicate extents need not be compressed using conventional data compression, saving computational resources and considerable time.
