@Jeff:
As a developer, companies will bring to me an idea for a program to promote that serves a particular purpose, and usually not even a prototype (no code written). If someone offered the same things Eassos Isoo Backup and System Restore claims, I would not need to install it or test it before I would want the same questions Peter Blaise has asked be answered. I would want to know how well did they think this project through before even considering it a viable product. It would be the same way even if they had a working product, even a user base already established. Peter did all of us a great favor by bringing up some important points, and after posting (even an additional post), he probably has other questions that should be asked. I would gladly hand a project such as this off to him so he could get those answers before I find out it is a great concept on the surface but a disaster in how it handles those unusual situations. Peter does not need to install it either to wonder about those same questions. I’m glad he asked all those questions. If Eassos were to answer every single question he asked (no exceptions), I would be more than glad to make a donation to Peter’s favorite charity, and match it for a charity that Eassos proposes. That is how much I am glad Peter asked; now if we could only get the answers to all of them.
@Peter Blaise
Good job; keep asking.
