Abstract
A high-availability cluster includes a subset of nodes having database instances where each database instance hosts a primary replica having primary databases or a secondary replica having corresponding secondary databases. An availability group includes a primary replica hosted by one database instance on one node and at least one secondary replica hosted by another database instance on another node, the secondary replica being a failover for the primary replica. A first backup preference is determined for a first availability group to identify a first preferred node for a first backup. A second backup preference is determined for a second availability group to identify a second preferred node for a second backup. The backups are triggered on the preferred nodes and the backups can proceed in parallel.
