I used their online backup as a last option. I have allready several NAS, but just in case I wanted our most important files stored somewhere else. It worked, they accepted our payments. And then came the day when we really needed our stored data, and then it was gone! We almost did not survive as a company because of this. Do not use Allmydata, they might delete your data.

allmydata is one of those hosting providers that just disappear on you, or take down your sites without a single warning, nor any explanation afterwards. they just don't care.
