A method for breakpoint continuous transmission is applicable to the case that a server may continuously transmit data of which the transmission is not completed directly from a breakpoint when interruption of data transmission occurs, and may find out modified data during system interruption, thereby maintaining data consistency at entire data transmission time points. First, the server receives a data element to be transmitted and a first snapshot corresponding to the data element to be transmitted that are transmitted by a client. When detecting an interruption signal, the server determines whether the first snapshot of the client is complete. If the first snapshot of the client is not complete, the server first determines whether metadata of the data element to be transmitted of the client is changed, and if the metadata is changed, the server first finishes receiving the changed metadata, and then continues the transmission.
