That's a good idea, actually, it's the practice in the banks where I work before that the backups are stored in different locations, that is to ensure that in terms of business disruption like flood and fire in one area, we can still get the other back up and would help the business to operate.

If we apply it in crypto, we know that data in a hard wallet is important to access our holdings, so if the hard wallet is destroyed due to fire or food, that means we also lose our funds.

So it's a great idea mate, I'm happy that you are thinking of a way to secure your holdings.
