My daughter is looking for a new backup program at work, for one server and one workstation. The server is SBS 2011, and the workstation is windows XP (although it may be upgraded in the next few years). She needs an easy, reliable backup system, with American-based support, that can do scheduled full and differential backups on external drives and will automatically erase the oldest backups as the drives fill up. She would like a bare metal backup. She is currently using Acronis and is very unhappy with it. Any suggestions?
