NDMP DirectCopy without VTL

By means of the NetBackup duplication feature, NetBackup can copy NDMP images between tape drives attached to an NDMP host. A typical usage is to copy images between tape drives within the same tape library. (Images can also be copied between tape libraries.) Like NDMP DirectCopy with a VTL, the copied data does not pass through the NetBackup media server or travel over the network.
