the "backup/DR" interface is for configurations with replicated NAS servers
on replicated NAS servers the production interfaces are active on the src NAS server and the backup interfaces are active on the (readonly) dst NAS server
use case is if you want to access the dst without a failover - for example for backup or testing or file restore
