The same thing happens on YouTube, by the way. There are basically two types of YouTubers, and I'm from the first group. The first being people, who delete absolutely everything after the recording and editing and doesn't store anything. What they have they have it on the hosting and thats it. The second group of people keep everything on CDs, racks of hard drives, cloud, servers, catalogued. And I can't have any outtakes because I have no outtakes, I only have intakes, if that makes sense.
