Disclosed is a data migration method in a peer-to-peer (P2P) network, the method comprising: when data migration is required, a source node requiring data migration compares the current data version of the data to be migrated with the data version corresponding to the destination node, determines incremental data and sends the incremental data to the destination node; the destination node recovers the latest version of the data according to the incremental data and the data stored in the destination node itself. Also disclosed is a data migration system in the P2P network. Using the method and system of the present invention can greatly reduce the data volume and migration time of data migrations in the P2P network, thus improving the data migration speed and reliability. |
