Network Data Management Protocol ( NDMP ) is a standardized interface through which it is possible to control backup and restore operations of NAS servers with backup software. The protocol was developed by the companies NetApp and Intelliguard (later acquired by Legato, which in turn were acquired by EMC ) and submitted to the Internet Engineering Task Force (IETF) in October 1996 to initiate the Request for Comments (RFC) process. NDMP is now supported by almost all backup software products even without this official approval.
Functions
Through the use of the otherwise necessary NDMP approach, all data lying on a NAS server, from a backup server from to mount to secure and from this, unnecessary. This reduces the load on the network, the NAS server and the backup server.
The following interfaces are defined in detail:
- Data Management Application (the backup software that sends commands to NDMP services over the network)
- NDMP Data Service (interface to the NAS system on which the data is stored)
- NDMP Tape Service (interface to the backup system on which the data is saved)
- NDMP SCSI Pass-Through Service (enables the backup software to send SCSI commands to devices connected to NDMP servers)
Usually this protocol is bound to port 10000 / TCP.
