Summary:The invention discloses a data backup method. The method comprises the following steps: respectively acquiring load information of each auxiliary end controller; distributing each auxiliary end logic sub-volume obtained by pre-division to each auxiliary end controller according to each piece of load information to obtain auxiliary end sub-volume configuration information; synchronizing the auxiliary terminal coil configuration information to the main terminal, so that the main terminal transmits to-be-backed-up data to a corresponding auxiliary terminal controller according to the auxiliary terminal coil configuration information; and processing the received to-be-backed-up data by utilizing each auxiliary end controller so as to complete data backup at the auxiliary end. By applying the data backup method provided by the invention, the selection strategy of the auxiliary end controller in remote replication is optimized, so that auxiliary end resources are fully utilized, and the data transmission performanc
