User-initiated backups in a DAG environment fail if initiated from a node in the DAG that is not currently active
User-initiated backups in a database availability group (DAG) environment fail if initiated from a node in the DAG that is not currently active for the virtual DAG name.
Workaround: Initiate the user backup from the active DAG node, or manually start the backup from the NetBackup master to properly start the backup.
