Zusammenfassung:The invention relates to a data recovery method and device, a storage medium and electronic equipment, and the method comprises the steps: receiving a notification message sent by a calculation node in a distributed graph calculation system, the notification message representing that the corresponding calculation node successfully stores the check point data in a persistent memory; when it is determined that all computing nodes in the distributed graph computing system successfully store the current check point data in respective persistent memories, generating a check point identifier corresponding to the current check point; and sending the check point identifier to each computing node, so that each computing node associates the check point identifier with the check point data stored in the persistent memory, and the associated check point data is used for the corresponding computing node to execute data recovery during recovery before obtaining the check point identifier corresponding to the next check poi
