NDMP simplifies NAS backup
The Network Data Management Protocol (NDMP) provides a way for vendors to improve storage management, especially for NAS appliances.
NDMP specifies a simple, vendor-neutral standard for communication between servers and backup software. Although it can be used by any kind of backup device on a network, it is especially useful for NAS applications because it allows centrally managing NAS devices with attached storage without loading down the network with the backup. Using NDMP, a central server can run the backup management software for the NAS devices on the network, instructing them to back up to local storage, such as tape drives. If the local backup devices are connected to the NAS appliance by Fibre Channel, the storage can be backed up at gigabit speeds with no load on the network except for the commands and management information sent back and forth from the storage management software to the backup devices. This can dramatically shrink the backup window when compared to backing up over the network.
A number of makers of backup devices and software, including Quantum|ATL, Connex (a Western Digital Company), Vixel Corp. and Syncsort Inc. are offering NDMP products specifically designed for use with NAS devices.
