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

After reading the previous discussion I think that you should get more than single drive to store cold backups. That way you can at least spread out the risk of single drive failing. 2TB spinning drives are pretty cheap today and if you have, for example, 4 of them, you can buy one now, write your backups to it and in 6 months buy another, write data on that and so on.

This way you’ll have drives with year or two difference on purchase date, so it’s pretty unlikely all of them fail at once and a single drive gets powered on and checked every other year or so. My personal experience is that spinning drives are pretty stable on the shelf, but I wouldn’t rely on them for decades. And of course even with multiple drives you’ll still want to replace them every 3-5 years each. Plus with multiple drives, if I were to build setup like that, I’d set up some sort of scripts or other solution where I can just plug the thing in and doubleclick an icon on desktop to refresh the data and maybe get a notification automatically that the drive you’re using should be replaced.

And for actual, long term storage, printouts are the way to go. At least in here you can get books made out of photo paper with your pictures. That’s one media which is actually stable over long period and using them doesn’t require a lot of technical knowledge nor hardware. But I’d still keep digital copies around, as the printouts aren’t resistant to things like house fire or water damage.
