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 not used them myself, but M-DISC sounds like what you’re looking for. There are a few other alternatives listed on that Wikipedia article, too.

      Thanks, I think the risk here is that there may not be hardware to read it.

      From the suggestions here I’m thinking a hard drive with USB connection would be best. It won’t last 50 years but instead I’d replace it every 5 years or so. I’d use an error resistant file system and plug it in each year to add the new files.

      This way I also get the chance to move it to newer technology in future instead of a new hard drive. It would then only need to survive for some period of time after I last replaced it, so there’s a good chance of it remaining readable for most of my life.

        M-Disc DVDs are readable by ordinary DVD drives. So you could simply put a USB DVD drive alongside those backup M-Discs on the shelf.

          Yeah that’s an idea. It does seem like I’d need a lot of disks though. And I don’t actually have a disk reader or writer at all at the moment.
