Abstract
Federated restore of availability group database replicas is described. A system receives a restore request associated with an availability group, and identifies a primary node in a cluster of nodes, the primary node storing a primary database replica associated with the availability group. The system identifies a secondary node in the cluster of nodes, the secondary node storing a secondary database replica associated with the availability group. The system removes the primary database replica and the secondary database replica from the availability group. The system simultaneously restores a backup database replica, associated with the availability group, as the primary database replica in the primary node and the secondary database replica in the secondary node. The system adds the restored primary database replica and the restored secondary database replica to the availability group.
