Retrieves version information from the remote Network Data Management Protocol
(ndmp) service. NDMP is a protocol intended to transport data between a NAS
device and the backup device, removing the need for the data to pass through
the backup server. The following products are known to support the protocol:
* Amanda
* Bacula
* CA Arcserve
* CommVault Simpana
* EMC Networker
* Hitachi Data Systems
* IBM Tivoli
* Quest Software Netvault Backup
* Symantec Netbackup
* Symantec Backup Exec
