Ok, say I am on vacations and my laptop turned brick. The SQL crashed and I need to perform a restore.

What do I do if only SSH keys are allowed? So I keep my key on a USB key? How is that safe to plug in into a computer?

Do I go around with a USB-Linux-distro with my key on it? What if in the border an official decides to keep the USB device I was holding on to.

How do you manage this situation?

You have other people on call to care for critical infrastructure.

I know many people keep an encrypted copy in various cloud or email accounts. Then all you would need is the encryption password and internet access to download the application to decrypt.

A USB smart card like a Yubikey NEO or 4 might be useful. Keys are securly stored in the card and never leave it. Alternatively, a USB smart card reader and a normal smart card, but this is physically larger.
