NDMP three-way backup

The NDMP three-way backup is also known as the remote NDMP backup.

During a three-way NDMP backup operation, a data management application (DMA) on a backup server instructs the cluster to start backing up data to a tape media server that is either attached to the LAN or directly attached to the DMA. The NDMP service runs on one NDMP Server and the NDMP tape service runs on a separate server. Both the servers are connected to each other across the network boundary.
