Loyd, thanks for this extensive response. It really helped me see what you are thinking. > In reality? > > We get more peace of mind.

Even gigibit ethernet is still formatted as ethernet with tcp/ip on top of it. tcp/ip is robust but not fast. > In short, BRMS gives us an offical way to placate the corporate office, and > better formalize our backup and recovery strategies.
