NOT the 1GB of data - make -2, -8, -32, -96 day incremental changes ( daily, weekly, monthly, quarterly ) ( alway make sure incrementals overlapp each other ( so that if the last incremental fails, you're still covered c) make a dvd and that is your "full" backup and send the dvd instead d) get a full or burstable T1 from a reliable isp so that you dont get any timeouts or lost connections c ya alvin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
