Google Email Continuity: A Plan B Server

Google's email services company, Postini, will let companies back up their Microsoft Exchange email servers with Gmail. An article on SF Gate reports that Google Email Continuity sits between a company's on-premises Exchange server and the public Internet and routes emails simultaneously to Exchange and to Google's Gmail service. Internal emails are synced to Gmail through an Exchange plug-in and in the event Exchange crashes, users will be automatically switched over to Gmail, where all their email and calendar information will be waiting for them.

"In addition to offering a cost advantage over Microsoft's own offering, this is a useful sales tool Google's pitch to get customers to swap out Exchange servers for the Gmail. If customers aren't sure they want to go completely into Google's cloud, they can check out Google Email Continuity for a while. The more Exchange crashes, the more they'll get used to using Gmail in its place."
