Tbf that's the matter of taste/preference. I'm have the completely opposite view to yours - I'm really attached to old vids, drawings, texts (that I made myself when I was younger). So I store and backup everything, even things most people would think of as unserious/unnecessary. It feels like a part of myself, a part of my story, you know, so I would be very upset if I lost it. And I can understand if someone have attachment to old films, books etc. I would say archiving old stuff is kind of a hobby in itself.

Although that being said, I can see advantages of your style - mainly less spending money on harddrives and time of setting them up and backing up stuff :)

I consider most data on my devices as replaceable, I would only back any of it up if the effort to replace it was much harder than the effort to back it up.

If you don't want to keep it that's fine, but if you have any recordings of commercial media (like say VHS tape recordings of broadcast TV) it would be of major help and contribution if you at least go through what you have and see if any of it is !lostmedia@lemmy.world

You'd be surprised at the things people are looking for, from old TV ads to TV channel interstitials and Bumpers to TV show episodes that aired once and was pulled, lost and never shown again
