The EU GDPR has requirements for processing (including storage) of personal data (much larger scope than US PII, but still nowhere near all data) in jurisdictions with legal adequacy for data protection.

You can find the current GDPR adequacy list at the EU’s EDPB site. https://commission.europa.eu/law/law-topic/data-protection/i...
