When he installed Mimosa NearPoint last November, Lawrence was looking for DR for Exchange, not CDP.

"I have a hard time keeping up with all the acronyms," says Lawrence. "Basically, we had to have something to let us recover from hardware failure or from our building being blown away, so we could still have email."
