Abstract
Federated back up of availability groups is described. A system identifies multiple availability groups scheduled for backup. The system logs in to a structured query language instance on an active node, identifies a primary replica for the first availability group, identifies a backup preference for the first availability group based on the primary replica for the first availability group, and identifies the backup preference for the first availability group as a preferred node for backing up the first availability group if the backup preference for the first availability group is on-line. The system configures backup storage based on a name of a cluster of nodes associated with the availability groups. The system backs up the first availability group based on the preferred node for the first availability group in parallel with backing up the second availability group based on a preferred node identified for the second availability group.
