  • Patent number: 10713135
    Abstract: A data disaster tolerance method, device and system is disclosed. Each node in a logic unit including a single master node and two or more slave nodes is monitored. If the master node is abnormal, the server acquires log information of the plurality of two or more slave nodes separately, the log information of the two or more slave nodes includes respective time points of data synchronization between the slave nodes and the master node A respective slave node of the two or more slave nodes having the time point of data synchronization closest to a current time is selected as a target node. A master-slave relationship in the logic unit is updated to change a role of the target node to that of the master node.
