What do people use for a shelf-stable backup (lemmy.nz)

I have backups on a backup hard drive and also synced to B2, but I am thinking about backing up to some format to put in the cupboard.

The issue I see is that if I don't have a catastrophic failure and instead just accidentally delete some files one day while organising and don't realise, at some point the oldest backup state is removed and the files are gone.

The other thing is if I get hit by a bus and no one can work out how to decrypt a backup or whatever.

So I'm thinking of a plain old unencrypted copy of photos etc that anyone could find and use. Bonus points if I can just do a new CD or whatever each year with additions.

I have about 700GB of photos and videos which is the main content I'm concerned about. Do people use DVDs for this or is there something bigger? I am adding 60GB or more each year, would be nice to do one annual addition or something like that.

I have 3 2 1 but I want the equivalent of a suitcase of photos in the cupboard. No family member is gonna be cleaning out my house as they move me to a rest home and stumble upon my Borg backup in B2 object storage. And if they do they won't have the key. I want something a bit closer to physical.

I think an extra drive for cold storage is a good idea. My main backups are automated, this one I can add any new files done in the last year once a year, then back in the cupboard. I just need to make sure I'm rotating the drives so I don't have the same one in storage for 50 years, and instead buy new ones every 5 years or so.

If this is your fear, why not just have a will or something that specifically describes what to do and where to go?

I have such a document, but it's not quite the same. I'm just as worried about my dumb ass losing the borg key and all data along with it...

I'm thinking a clearly labelled hard drive with instructions, rotating the hard drive with a new one every 5 years or so.

Exactly. I have a document for my SO that describes what to do if I pass (where the money is, how the WiFi is set up, various important accounts, etc). It's not a will (nothing about who gets what, though that's assumed by the state to be my SO, or my kids equally if we pass together), just a document that explains the stuff I handle.
