Multi sig questions

Hi,

Have some questions regarding multi sig set ups.

As I understand it the 2/3 setup pretty much means that if one Hardware wallet breaks I'll be able to still move the btc.

What happens if you would use let us say Electrum on a computer. What happens if that computer breaks but none of your hardware wallets?

Is it best practice in that case to store your multi sig wallet file on the cloud so you can access the file on a new computer, thus still accessing the money?

And if one hardware wallet breaks, my initial thought would be to but another 3rd one, set up a new multi sig adress and then make a transaction with the remaining 2 from the old set up. Or should I restore the current wallet and just add the new hardware device?

What are best practices?
