Ah that's right. I feel like there was some other backup company using Amazon's storage... Oh well.

Andy, at best the blurbs you posted could be read either way, so they should have been clearer. But I don't think they expected anyone to do what you're doing. Those blurbs certainly don't explicitly say you can store inactive computers indefinitely.

I still think you're using it as storage and not really a backup. I consider a backup to be a second (or third or fourth) location for the copy of a file. You only have those files in one place, which is never good, for reasons just like this.
