¿Que és el protocolo NDMP?

Como revisión de un proyecto que contempla Backup & Recovery Strategies me he encontrado con el protocolo NDMP.

Según la Wiki lo describe como:

NDMP, or Network Data Management Protocol, is a protocol invented by the NetApp and Legato companies, meant to transport data between NAS devices and backup devices. This removes the need for transporting the data through the backup server itself, thus enhancing speed and removing load from the backup server.

Soportado por la gran mayoría de herramientas de copias de seguridad tal como indica la descripción de la WikiPedia permite el backup directo entre máquinas y las cabinas de discos, disminuyendo el tráfico de red y la carga en los servidores de backup.

Como resumen de la Web destinada al estándar se indica:

The NDMP initiative was launched to create an open standard protocol for network-based backup for network- attached storage. The protocol allows backup and network-attached file server vendors to focus investment on functionality instead of excessive porting, and gives users an unprecedented level of choice and interoperability. The protocol is called Network Data Management Protocol (NDMP). The objective of the protocol is to help address the problem of backing up networks of heterogeneous file servers, including dedicated file servers (“filers”), with any of several backup applications. Prior to the existence of the protocol, backup vendors would port to and track many different platforms and OS releases, with filers presenting a special challenge because of the desire to have them be backup-ready (eliminating the need to specially install backup client software). Dedicated file server vendors tried to make sure that all the newest, most important backup applications were available for their current and new releases.

  1. When beginning investing in the stock market, it is wise to invest a small amount into many
    different stocks. The stock market is risky, and if you just invest in one
    company, and it happens to not do well. You will be
    losing a lot of money. If you have more than one stock, you will be more
