Abstract: A deduplication method and apparatus are provided. In the method, a fingerprint record that includes a plurality of fingerprint record items is first obtained, and at least two first fingerprint record items that include a same fingerprint are then determined from the fingerprint record. For example, the at least two first fingerprint record items each include a first fingerprint, so that deduplication is performed on data corresponding to the first fingerprints in the at least two first fingerprint record items. The at least two first fingerprint record items are deleted, a stub of the first fingerprint is recorded in the fingerprint record, and the stub of the first fingerprint indicates that the first fingerprint is a duplicated fingerprint.
