What is NDMP?
Network Data Management Protocol (NDMP) is a protocol that was initially designed to improve data backup and recovery performance by eliminating the server from backup or recovery processes.
Network Data Management Protocol was originally developed by NetApp Inc., but the list of data backup software and hardware vendors that support the protocol has grown significantly. And currently, the Storage Networking Industry Association (SNIA) oversees the development of the protocol.
With NDMP, heterogeneous network file servers communicate directly to a network-attached tape device for backup or recovery operations. Without NDMP, an administrator must remotely mount the network-attached storage (NAS) volumes on their server and back up or restore the files to directly attached tape backup and tape library devices.
NDMP separates the data from the control path, reducing the amount of traffic on the network. An NDMP backup or recovery can be performed at the local site (disk and tape in the same facility), but managed remotely. Obviously, using a well-architected NDMP-enabled data backup strategy saves personnel time and network resources.
