Abstract
A deduplication processing method is provided. A storage device includes a plurality of memories and each memory includes at least one physical block. Parameter information of an initial memory representing any one of the plurality of memories in the storage device is obtained. The parameter information includes at least one of a weight of the at least one physical block in the initial memory or a space usage of the initial memory, and the weight of the at least one physical block corresponding to a next write time point of the at least one physical block. A deduplication weight of the initial memory according to the parameter information of the initial memory is obtained. A target memory having a largest deduplication weight from initial memories is selected and deduplication processing on the at least one physical block of the target memory is performed.
