How do you backup/protect your critical documents?

I'm working on improving my personal backups and making sure I have scans of all my critical documents, e.g. birth certificate, passport, social security card, MFA backup codes, etc... the important stuff.

Right now I'm actually not using any cloud file storage, just local backups. Although I have a paid Proton account so Proton Drive is an option for me.

Even though Proton Drive has zero knowledge security, it still feels wrong to just bundle up all of my identity …
