Abstract
A technique for performing deduplication traverses a deduplication database and assigns digest values in the database to buckets, where each bucket covers a respective range of digest values. To deduplicate a particular candidate block, the technique generates a digest from the candidate block and searches for the computed digest in a subset of the buckets, where the subset is selected based on the computed digest. If a target block providing an exact match or a suitably close partial match is found in the subset of buckets, the technique effects storage of the candidate block at least in part by providing a reference to the target block.
