The last time we looked at the chunking process in data deduplication engines (“Your Mileage Will Vary: Chunking”), we were looking pretty favorably at variable chunking that used the contents of the data to assign chunk boundaries. However, as deduplication moves from backup appliances accepting tape, or other backup application-specific format data, into backup applications and primary storage, the advantages of fixed-chunk deduplication start to become apparent.
