SnapVault backup between two different clustered Data ONTAP 8.2 or later systems requires what type of intercluster communication?

Cluster Vaulting LIFs is not a valid LIF role or type in clustered Data ONTAP 8.2.

Cluster Replication LIFs is not a recognized LIF role in Data ONTAP; the correct role is intercluster, used for peering.

Cluster Peering LIFs, also called intercluster LIFs, are a required and specifically designated LIF role in clustered Data ONTAP that handle all intercluster communication including SnapVault and SnapMirror traffic. Cluster peering must be configured using these LIFs before any SnapVault relationship between clusters can be created. Without a functioning peering relationship established via these LIFs, no vault transfers can occur.

Cluster Backup LIFs is not a valid LIF type or role in any version of clustered Data ONTAP.
