What exactly is this setting for?
Can I set it to "50", so that I can't upload more than 50 GB? Which would mean, that I'd never get charged for additional used space. This was a problem I thought of … if I'm backupping happily, and reach the free 50 GB, I'd have to pay for it.
Or does it something different?
