Abstract
Disclosed in the present disclosure 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, and when the start time period is in the main service running time period, it 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 Application Programming Interface (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.
