Having used 1click for over a year, I would definatly say that its the EASIEST backup software to use. Most problems that one runs into - i would say 90% - are from what I have seen... user error.... or conflicting programs that are ran in the background.

1click support reply very quickly... or you can even ask us for help in the 1click forums. By "we" i mean other 1click users - we are a friendly bunch
