I have a Windows 2003 Server running off of a SATA hard drive. This server has AD and Exchange 2007 on it. In need to back up the server in case something happens. I am looking for a solution that is affordable. What is the best way to image or backup this drive so that if I need to restore the server data it will be fully functional? I am wondering if I just imaged the drive if this would be a safe and affordable way to go. What would you recommend and what is an affordable option? I am a small business and have a limited budget.
