The nsrazure_save command is included with the installation of the NetWorker Extended Client software. This requirement is documented in the Dell NetWorker and Azure VM Snapshot Integration Guide: Support for NetWorker | Manuals & Documents 

The Extended Client package is included with the NetWorker installation bundles downloaded from: Support for NetWorker | Drivers & Downloads
