LAN-free backup takes backup traffic off the LAN:
In this backup model, the tape device is attached directly to the SAN,
either via a native SAN interface or via a gateway.
The server takes data from disk over the SAN, and sends it to tape over
the SAN.
The SAN is much more efficient than the LAN at handling large data
flows, so faster, more efficient tape libraries become viable. A smaller
number of tape drives can be shared between many servers, so the cost
of these high-end tape libraries can be shared over several servers and
applications.
