Ever since I upgraded from Windows 7 x64 Pro to Windows 8.1 x64 Pro I cannot get Keriver to backup to my NAS. I have reached out to Keriver with no response. I am looking for an alternative that is similar in features, speed, and is intuitive. The replacement software must be able to backup SSD's and across a network to a NAS. Would love something that has the ability to open snap shots from the OS image and recover individual files or the entire OS if needed. Cost does not matter to me in this case. I am willing to purchase what ever I need. What suggestions are out there?
