A processing system of data de-duplication includes a client and a server. A characteristic value of each data block is compared with characteristic values stored in the client. If the same characteristic value exists in the client, the data block corresponding to the compared characteristic value is deleted. A server data management module is connected to a client data management module through a network. If the characteristic value does not exist in the server, a corresponding data block is obtained from the client, and the new data block and the characteristic value are stored in the server. A file management module records a storage address of the data blocks in the server into an index file. In this way, the server is not required to perform all data de-duplication processes of the clients, thus reducing the occupation of bandwidth and improving the processing efficiency of the server. |
