Copy those photos now. 20 years ago I was obsessed with burning DVD’s to last a long time. I researched the best quality media that was rated for 100 years (Verbatim AZZO). I used diagnostic tools from a specialized cd burning forum that showed the pi/pio errors so you knew if you had made a quality burned DVD. (Even though burners were rated 2x-16x, each burner had a sweet spot of minimal errors for a particular media. In my case it was 4x.)

Last year my niece said the wedding photo DVD I gave her 15 years ago was unreadable. I checked my extra copies that had been kept in the basement in black dvd storage containers and they were bad too. Fortunately I had backups on hard drives that I migrate every few years from server to server.

Unpowered USB or SSD’s that haven’t been refreshed are only good for 10 years too.

Every year I pick out my favorite pictures of the year and print a physical photo album.
