I am not technically advanced, so I have to admit that I have had some problems figuring out this component. However, the fast support offered through the developer's support ticket system has been GREAT. When I have been confused, he has been patient. When I encountered permissions problems, he solved them.
Granted, the software would benefit from a proper, but brief instruction manual, to give both the big picture of what it does, and how to do the details. But in the end, it does clone sites, and it does backup everything with one go. That is what it claims to do, and it does it well.
