About the OpenStorage direct to tape process

If one host provides both NDMP FSE and NDMP tape server functionality, one
media server functions as both the read and write server.
To simplify OpenStorage configuration and management, Symantec recommends
that you use one set of media servers for all OpenStorage activity. The media
servers then can function as either read or write side servers for direct to tape
operations. They also can function as data movers for other OpenStorage
operations.
For each media server in the set, do the following:
Configure logon credentials to the OpenStorage storage server.
Install the NetBackup for NDMP software.
Configure logon credentials for the NDMP FSE host (if required).
Configure logon credentials for the NDMP tape server host.

The destination storage unit must be NDMP. You cannot use a storage unit
group.
You cannot make multiple copies with one copy operation.
Backup images are not multiplexed when written to tape.
The following is an overview of the direct copy to tape process:
NetBackup verifies that the image to be duplicated resides on an OpenStorage
device.
NetBackup verifies that the disk appliance NDMP host supports the
OpenStorage direct to tape specification.
NetBackup selects the write side media server, a destination tape drive, and a
tape volume.
NetBackup selects a media server that has credentials to the NDMP tape server
host. The media servers NetBackup considers are listed in the destination
storage unit.
