NDMPCopy is not a software on the filer. The ndmpcopy command is a utility
that you install on a UNIX host and "enables a filer administrator to transfer
file system data between filers that support NDMP v3 or v4 and the UNIX file
system (UFS) dump format."

Since NDMPcopy is not running on the filer itself, then how do you expect
NetWorker's nsrndmp_save to invoke it?
