Hello,

First question: Is it native ATM that you're using or are you using CIP o=
ver
ATM. If it's the second one you'll never get a performance of 15Mb/sec.
We've also an ATM configuration and the most we get is 11Mb/sec by using
CIP on ATM.
Second question: Which remote hosts are you backing up. Microsoft or Unix
servers and what OS?

Regards,
