You create an availability group named HaContoso that has replicas named Server01/HA, Server02/HA, and Server03/HA.
Currently, Server01l/HA is the primary replica.
You need to ensure that the following requirements are met:
Backup operations occur on Server02/HA.
If Server02/HA is unavailable, backup operations occur on Server03/HA.
Backup operations do not occur on Server01/HA.
How should you configure HaContoso?
