Cluster data to be backed up is transmitted to a first data storage module for storage through a first physical isolation module which discontinuously connects or disconnects a network path, and the cluster data to be backed up in the first data storage module is transmitted to a second data storage module through a second physical isolation module which discontinuously connects or disconnects the network path. When the first physical isolation module and/or the second physical isolation module are/is in a network open circuit state, the first data storage module and/or the second data storage module are/is in an offline state, secondary physical isolation of the to-be-backed-up cluster data is achieved, and the safety of the to-be-backed-up cluster data is improved through a double physical isolation mechanism.
