Eliza, It may help if you think of LAN-free backup as client-to-device data movement, and server free backup as device-to-device data movement. In the case of LAN-free backup, the Storage Agent code (a stripped-down version of the TSM server) is running on the client, consuming memory and CPU resources when redirecting the data from disk to the SAN-attached tape. The data does have to be channelled through the client, then (back) through the SAN to the tape in the shared library. Server-free backup would take the resources of the client almost entirely out of the picture; the client would only transfer the metadata across the LAN. But we're not there yet... Ted
