I got my first digital camera in 2001 and still have all the photos from then as well as all the images I downloaded from the internet starting from 1991 through Usenet groups.
I scanned all of my dad's old photos going back to 1965 and have our family photos going back to the 1930's.
Everything is backed up twice and verify every file checksum twice a year.
I know not everyone is a computer expert but 1) we are on Hacker News 2) prebuilt NAS systems have a lot of these features now and can backup to another unit.

This. Those arguing it's hard for their grandma: I can understand. Those arguing it's hard for themselves: there are probably better websites to frequent for them and I dispute their "hacker" status.

How do you do the checksum? Mine is added to the filename:
meaning that file has a Blake3 checksum beginning with 7e282693a4. I've got both verification script doing random sampling (where at times I randomly verify x% of the files) and my rsync wrapper script doing a rsync dry-run (if the dry run detects a checksumed file that supposedly needs to be rsync'ed I'll verify the checksums and detect the bitrot'ed file if any).
HDDs (offline and both on-site and off-site), SSDs, dedicated servers, server at home running ZFS, ...
I plan to buy used LTO tape gear too.
P.S: I still have source code from DOS stuff I wrote in 1991 so there's that.
