We are a non-profit with limited funds. We have an 2003 Exchange Server that is a few years old. Our e-mail system is critical to a few of our operations. What I'm looking for is the QUICKEST way to get the e-mail backup in the event the server crashes. I have a new server that hasn't been built yet so it can be used if I can find a solution. I've heard of Acronis True Image and have used it on Workstations, but not servers. I've also heard of Double Take. I think Double Take replicates the Exchange server on another identical machine so if the 1st fails, the other takes over.
I'm looking for some Critical advise from Experts-Exchange.
