Abstract: Embodiments of the present invention provide a data synchronization method, and a device. The method includes: receiving, by a server, a synchronization task message sent by a first user equipment, where the synchronization task message includes: a synchronization task instruction and information about a to-be-synchronized file; determining, by the server according to the synchronization task instruction, historical synchronization operation information corresponding to the to-be-synchronized file, in historical synchronization information stored in the server; and sending, by the server, a response message of the synchronization task message to the first user equipment, where the response message carries an execution result of the synchronization task instruction. In the technical solution of the present invention, it can be implemented that a server records historical synchronization information used for a data synchronization between user equipments in a network system, thereby avoiding a problem of repeated file synchronization that may exist in the prior art.
