Really easy to use, I used dropbox for my backup and it worked flawlessly.
Settings page was well laid out and easy to understand (unlike some plugins).
Yep, it's a winner!
(only 4 starts because i've only used it for an hour and only made one back-up. so i cannot comment on how it works in the long run, I have scheduled my back ups to happen weekly for now but I am confident it will work as advertised)
