Summary:Disclosed in the present application are a data recovery method and apparatus for a dual-machine hot standby system, and a medium, which are applicable to the field of data processing. In the method, a main service running time period and a start time period are determined by means of a backed-up start-stop operation record file, wherein when the start time period is in the main service running time period, this indicates that a split-brain phenomenon possibly occurs in a dual-machine hot standby; and record information of a database backup record file within an initial split-brain time is further read, so as to determine the possibility of split-brain data, a final split-brain time is automatically determined, an API calling information file is read according to the final split-brain time, so as to recover data, and operation information of a system during brain splitting is automatically restored. An optimal split-brain time is selected as a recovery time point for recovery, such that the existing situation
