In the remote NDMP scenario, there are no Fibre Channel connectors present in the cluster. Instead, the DMA uses NDMP over the LAN to instruct the cluster to start backing up data to the tape server—either connected by Ethernet or directly attached to the DMA host. In this model, the DMA also acts as the Backup/Media Server.
During the backup, file history is transferred from the cluster over NDMP over the LAN to the backup server, where it is maintained in a catalog. In some cases, the backup application and the tape server software both reside on the same physical machine.
OneFS remote NDMP backup also includes intelligent IP selection functionality. This enables backup applications such as Avamar and Commvault to select the most desirable interfaces and preferred network for NDMP traffic.
