NDMP ended the monopoly of the Backup software Vendors and File Server vendors :

With the invent of NDMP, we have only one "universal agent" for the network- attached file servers to be used by any of the centralized backup administration applications. Earlier Backup vendors had to "develop" many cleint/agent software which would understand different OSes needs,

for ex:
1. Windows agent for Windows Servers.
2. Unix angent for Unix/Linux Servers.
3. Solarix agent for Solaris Servers.
4. Mac agent for Mac Servers.


This not only led to more cost incur on the vendor side for development of these agent, but also customers had to bear the cost of so many agents, further dedicated file servers had to be mounted to such OS so that their data could be backed via NFS or CIFS (SAMBA) file level protocols. Most serious drwabacks were , data had to travel via networks to the central backup application where "tape/library" was attached.
