NDMP DirectCopy with VTL
The NDMP DirectCopy feature uses a VTL that has an embedded NDMP tape server using the NDMP protocol. The embedded NDMP tape server moves the image from the VTL disk directly to a physical tape. The image does not pass through the NetBackup media server or travel over the network.
Note:
In a VTL environment, a NAS appliance is not required. The VTL emulates a NAS (NDMP) host. The VTL requires NDMP tape server functionality.
The following figure represents a VTL from two perspectives. It shows the actual hardware present in a VTL configuration and the configuration from the perspective of NetBackup.
