> some external HDDs that I keep outside the home.
Personally, I'm not remotely meticulous enough for that to work. Properly rotating drives sounds like a lot of work if you want to be rigorous about it. You start with running the backup to drive A, then shipping that drive a couple hundred miles away (to be properly location redundant), and then next week, run the backup to drive B, ship that drive a couple hundred miles away, but then at some point, you're going to want drive A back, so you can rotate drives and put a more recent backups on it. How do you retrieve those external drives, and consistently?
And then while the drive is in transit, and hopefully not lost, you don't have access to it, it's not an online (referring to its availability) backup solution.
So I mean, I do perform backups to an external HDs which I also keep offsite, but because that's nowhere near as rigorous as what teams of engineers and data center techs can do with a much larger budget, I supplement my backups with a cloud storage solution. And I encourage you to do so as well (especially considering encrypted backup services), but you do you.
As far as the mdisc; I mean it's interesting, but I'd also consider getting an LTO tape library. They're more purpose build for backing things up, and my personal opinion is they're going to be better for longevity given everything else.
