Earlier quoted context omitted.
It's $9/computer so if you have another computer, you can't use the same 5 TB quota. I'm banking on most people having less than 5 tb per computer to backup. It's kind of like what Backblaze Personal does for their unlimited plan but slightly lower tier I suppose (since there is no way I could do unlimited).
You probably will want to have something to discourage the data hoarders. They might not be many in numbers, but they can rack up quite the TB count.

You have to zoom in to see the meaningful information. It can be super surprising to developers and IT people (like us) to see a lot of customers have less data than you might think.
When we started we had no idea what might come of all of this, so it was "stressful". :-) So I welcome another backup client developer to our club, and hope this can help them out.
