Abstract
A data recovery method includes executing a recovery program of the DFS to periodically generate backup data of the DFS. In response to received operations of a user on a client device, information in relation to the received operations is stored in a main computing device. When a master node of the DFS is running abnormally, the data recovery program is executed to restore the data of the DFS using backup data having a creation time closest to the current time. Specified operations with later creation times are determined. Information in relation to the specified operations is acquired from the stored information. According to the acquired information of the specified operations, each of the specified operations is re-executed.
