Abstract: A data replication method includes obtaining differential data information corresponding to differential data, where the differential data information includes a storage address of the differential data, and a determining value of the differential data. The data replication method comprises replicating the differential data from the primary volume to the secondary volume according to the storage address of the differential data that is located in the primary volume when the determining value is not less than a preset threshold. The data replication method comprises taking a snapshot for the primary volume when the determining value is less than the preset threshold and replicating the differential data to the secondary volume.
