The disclosed embodiment provides a method, device and storage medium for deduplication of an object storage system, which determines the target granularity for deduplication of the object storage system, which is the object granularity or the slice granularity; obtains the first check value of each data of the target granularity in the object storage system, and screens out the data with the same first check value from the object storage system to determine as duplicate data; adds, by taking one data in any group of duplicate data as the reference data, a soft link to the metadata of other data except the reference data in any group of duplicate data to point to the reference data, and recycles the storage space of other data.
