NetBackup media servers manage the operations. The media servers require the
NetBackup for NDMP software and specific NetBackup release levels.
See “About media server requirements for OpenStorage direct to tape” on page 70.
How to configure OpenStorage direct to tape is described elsewhere.
See “Configuring OpenStorage direct to tape” on page 100.
About NDMP requirements for OpenStorage direct to tape
If the NDMP requirements are not met, the images are still duplicated. However,
the copy operation uses the traditional duplication method of reading the image
through the NetBackup media server and writing out to tape.

NDMP requirements for OpenStorage direct to tape
DescriptionNDMP functionality
The OpenStorage disk appliance requires an NDMP server that supports the OpenStorage
direct to tape specification. The Symantec OpenStorage Partner Program publishes the
specification. The direct to tape feature uses a subset of the NDMP File Service Extension
(FSE) commands.
The host that provides the NDMP FSE functionality can be one of the following entities:
■ The disk appliance storage server.
See “About OpenStorage storage servers” on page 61.
■ An alternative name (that is, interface) for the storage server.
■ A separate host that interacts with the disk appliance. The host must be directly
connected to the disk appliance.
NDMP File Service
Extension
Direct to tape requires an NDMP tape server for the destination tape library. The NDMP
tape server must support NDMP v4 or later.
The host that provides the NDMP tape server functionality can be one of the following
entities:
■ The same host that provides the NDMP FSE functionality.
If one host provides the NDMP FSE and NDMP tape server functionality, the tape library
must be attached directly to that host. Data does not travel over the network.
See Figure 8-2 on page 69.
■ A host that is embedded in the tape library. Data travels over the network.
See Figure 8-3 on page 69.
■ A separate host to which the tape server is directly attached. Data travels over the
network.
See Figure 8-4 on page 70.
