That's easy to prevent, by keeping multiple backups on different locations.
That's what everyone should already be doing for every back up, but even so, that doesn't mean we should opt to use fragile back ups which are easily rendered useless.
Despite that, I'm pretty sure I can come up with many different methods that will never get hacked.
I know I don't have to point this out to you, but not getting hacked is not the only aspect to consider when creating a new wallet. No point using some overly complex method to ensure you will get hacked which then results in you being unable to restore your wallet.
