Abstract: A node disconnection rotation may be performed on an active synchronizing node pool of a multi-node replication system. The node disconnection rotation may ensure that at least one node is disconnected from the active synchronizing node pool at any given time. A disconnected node does not synchronize with other nodes during the time that it is disconnected. A disconnected node may, therefore, serve as a designated survivor, from which the system may be restored, when other active nodes are subject to a cyber-attack. Although the disconnected designated survivor node may potentially be compromised, it may be sanitized of any malicious contents prior to restart.
