Abstract: The present disclosure relates to the field of communications, and in particular, to a network data rollback method and a rollback device. The method includes, when data rollback needs to be performed, comparing a data snapshot at a second time stamp with a data snapshot at a first time stamp to find different feature data; and selecting, from the different feature data, feature data that needs to be rolled back, and performing data rollback according to a preset rollback rule, so as to roll back a part or all of network data at the second time stamp to a network data state at the first time stamp.
