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.

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.

Yeah I will read up on it, thanks for the tip!
