Why do you have to carry your backups around when you are travelling or moving abroad?

If you want to keep your backups safely, you should keep them at safe locations like somewhere at home.

If you want to use your bitcoins when you are traveling but with less harmful effects on your main wallets, you can create a new empty wallet, and send part of your bitcoin from a main wallet to a new one. These part of your bitcoins will be used when you are traveling.

If you lose it, you lose your sub-wallet, not your main wallet. You won't lose your backups when traveling.
