Requirements to use NDMP DirectCopy for image duplication
When NetBackup uses NDMP DirectCopy to duplicate an image, note the following:
For the destination for the duplication, you must designate an NDMP storage unit in a VTL or in a physical tape library.
An NDMP tape drive must be available to mount the source image. The NDMP tape drive can be one that was defined in the VTL, or it can be a physical tape drive in a tape library.
Setup instructions are available.
If these two requirements are met, NDMP DirectCopy is enabled. NetBackup copies the image directly to the designated storage unit without using media server I/O or network bandwidth.
