SJG70  This backup software does all that I want (backing up my harddrive, cloning, maintaining a copy of my PDF library on a Flashdrive). I think their support deserves some praise: they recently very efficiently resolved a problem I was having, quickly providing me with very clear, comprehensive information. In fact it is probably the most professional support experience I've had. They obviously want the software to work for you.
