It totally is hoarding, I definitely admit to that. And I do the cloud backup because it's pretty safe and "immortal" as long as you keep paying. Nothing is permanent, but backing it up to another physical drive invites the possibility of ultimately losing both drives and the data itself (my last apartment building almost went up in flames because someone couldn't responsibly use an oven). I think there's some scientist's law (whom I can't remember of course) stating that data doesn't truly exist until it's stored in 3 places. But anyway, using dropbox, I can delete all the originals and free up tons of space repeatedly while only keeping this weird sort of linked file for each while it sits in the cloud. That way, if I want to do a montage or Youtube shuts my channel down, I still have the videos. I plan to someday open my own website if I ever get big enough. Maybe.
