EVO backup Question

[searcher61]

I came from a TP2 where we could backup the entire phone. I also realize there are backup programs that, if the phone is rooted can back up everything. I currently have tried mybackup Pro, and Astro...but what I really need is a way to back up everything except the OS .... so I can reset my phone back to factory settings. Try a couple of things and then restore back to the way it was easily and quickly. I have 5 email accounts on my phone and have to set them up after each reset and restore, I should be able to back them up. I am NOT rooted now... and would like to do this without rooting. We should be able to restore all the files needed over the top of the OS and be back in business, correct?

Anyone help?
