I have a Blue Ray burner on my PC that I used to make backups of stuff on.
At most I’ve gone through 3 spindles if discs. It’s been a year or more since I bothered.
In storage there are containers of burned CD and DVD media that haven’t been touched since they were made.
I keep little of importance on the box. Photos and video go to certain places. A few docs live on jump drives that get edited sometimes.

That’s what I do as well.
I even purchase ‘out of region’ discs that I rip to .MKV files and stream them to my TV.
