- Simply copying your data to a second hard drive in the same machine protects against hard drive failure.
- Second disconnected hard drive protects you from ransom-viruses and accidental erasures.
- Second disconnected hard drive on the other side of the house gives you some protection from a fire (caught early enough).
- Second disconnected hard drive in another building some distance away protects against small disasters (eg. randomly directed tornado).
- Second disconnected hard drive in another region protects against large disasters (eg. single nuclear strike).
- Second disconnected hard drive in another country protects against national disasters (eg. invasion, multiple nuclear strikes).
- Second disconnected hard drive on another continent protects against major disasters (eg. moderate asteroid impact event)
...and so on. But all of these can be protected against by simply having 3 backups.
Except bit rot. That shit's inevitable.

I'm not really sure if worrying about my hard drive will be something high on the priority list in many of these events.
