Abstract:
A solution to deduplication in a storage system is disclosed herein. In this solution, a controller stores, at a first storage address, a data block that is written for the first time, and inserts, in a fingerprint table, a first fingerprint of first data that is written for the first time, but does not establish a mapping relationship between the first fingerprint and the first storage address. When receiving subsequently written second data to be written, the controller allocates a second storage address to the duplicate second data, stores the second data at the second storage address, and establishes a mapping relationship between the first fingerprint and the second storage address in the fingerprint table. This reduces an amount of data in the fingerprint table.

Claim (Index 13):
The storage system according to  claim 12 , wherein the controller is further configured to delete a fourth fingerprint, in response to determining that no storage address corresponding to the fourth fingerprint exists, and duration for which the fourth fingerprint exists in the fingerprint table exceeds preset duration.
