Abstract
Backing up availability group databases configured on multi-node virtual servers is described. A system identifies an availability group scheduled for backup. The system determines whether the availability group is configured on at least one virtual server in a cluster of nodes associated with the availability group. If the availability group is configured on at least one virtual server in the cluster of nodes, the system retrieves information from a server in the cluster of nodes. The system uses the retrieved information to identify a database replica that is preferred for backing up the availability group. The system identifies a virtual server, in the cluster of nodes, that is associated with the identified database replica. The system identifies a node for backing up the availability group by identifying an active node from the nodes in the identified virtual server. The system backs up the availability group via the identified node.
