I had some problems early-on (noted in comment below). I contacted the developer who worked with me to troubleshoot the issue. Ultimately it was an unusal situation in my system setup, and he was able to get to the root of it.

Now that the application is working correctly, it is such a pleasure to use. It is very simple to work with, very intuitive, and quite nicely thought out. I was able to get the application working without reading any manuals or instructions and it functions quite well.

Best backup application I have tried thus far.

In addition, it was a pleasure to have the developer so integral to my success. He was extremely responsive and helpful.
