dump(8) can do a dump to a specified file, which is also how
you dump to a tape device other than the default tape. Does your
MVS system have the NFS server support running? If so, how about
dumping to a file on that server via NFS? That way you wouldn't
need rdump(8). If your MVS system doesn't have enough disk space
to hold a complete backup cycle, you could then offload each dump
file to tape from MVS once it had been created via NFS from your
DECstation.
