Thanks everyone. It seems like it's as simple as the Cat5 cable is the bottle neck. I think DD does have a pre-backup dedupe, but only if it's talking to a server with a client loaded. Wouldn't help with backing up file shares on an EMC SAN.
Somehow I need to figure out how to get data on 1 EMC SAN(acting like a NAS) to get to a backup appliance with speed. Without dropping 10G money. lol On Tue, Apr 9, 2013 at 2:46 PM, Richard Stovall <[email protected]> wrote: > Good point. In that respect, DD probably shouldn't be considered a > 'backup' product.
