ndmpcopy - transfer data between filers using NDMP
Ndmpcopy transfers data between filers using the Network Data Management Protocol (NDMP). When you use rsh to perform this transfer, the data flows from the source machine to the rsh host and then again from the rsh host to the destination machine. This can put a double load on the network and unneccessary load on the rsh host. With ndmpcopy, data is transferred directly from the source machine to the destination machine, and the NDMP host and network are not burdoned with the extra load. When you run ndmpcopy it will contact the NDMP server processes on the source and destination machines and authenticate the connection. It will then initiate a backup on the source machine and a restore on the destination machine. The transfer will happen between the two machines directly, only burdoning the NDMP host with status messages instead of all of the backup data. Initial tests have demonstrated double the performance when using ndmpcopy instead of rsh.
