I am a 'newbie' and manage two not-for-profit sites. I sleep peacefully because of this extension. It was easy to install, the backups work before I have had a chance to think about what's happening (the sites aren't large) and the upgrade installer works just as well. I couldn't be more pleased with the product. I haven't had to recover either site as yet but have worked through the process and am confident that I could manage that. I would recommend this to anyone. A big 'Thank you' to the developer.
