Comment on What do people use for a shelf-stable backup

In your scenario, I’d be looking at XFS or BTRFS for your live data, especially when taking photos into account. They’ll self-repair files that may run into decay issues, which I’ve seen a lot of with photos in all formats. Since you already keep off-site backups, I’d then just keep an extra drive around that you snapshot to from time to time.

So my offsites are an incremental backup, but at some point the oldest version is gone. I am keen for a completely separate, long term snapshot of what I had that could be thrown in a cupboard, and any random family member clearing my house out as I get moved into a rest home at 108 can go through the photos and find a good one to put on my headstone.
I am also keen for protection against doing something dumb and losing everything (like losing my hard drive and finding out for some reason I can’t access my backups because I lost the encryption key because I put it in bitwarden and they shut down years ago and I never moved the key over because I forgot it was stored there).

ZFS and BTRFS both provide that functionality. Have a look into the features.

So the drive doesn’t need to be hot, I can just plug in once a year and it auto-repairs?

No, the “live” filesystems will repair themselves when they detect problems. They keep revisions of your data, and run checksums constantly. When they find a file has inadvertently changed without access, it will restore said files. Think of it like Mac “Time Machine”, but it’s just the filesystem . You can restore stuff from points in time when needed.
Just read up on it.
