How to Review Security Before Letting a Supplier Store Business Backups

A supplier-held backup may contain more data than the supplier needs to provide its service. Encryption, access, retention, deletion, and recovery responsibilities can be unclear unless they are reviewed before data is transferred.

What to check

Identify backup contents, data classification, encryption and key custody, storage region, supplier staff access, retention, deletion evidence, breach notification, and restore support. Confirm contract and operational ownership.

Recommended next step

Limit backup scope, protect encryption keys under an approved model, and define retention and deletion duties. Test restore access and review supplier controls when service scope changes.
