Explanation
Encryption is the most important privacy control for backups because backup media is highly portable and often stored off-site, making it more vulnerable to physical theft or unauthorized access than primary production systems. If backups are not encrypted, a lost or stolen tape or disk exposes all the personal data they contain. Incremental (B) and differential (C) describe backup strategies related to efficiency and recovery time, not privacy. Pseudonymization (D) reduces privacy risk but may not protect data fully and is not consistently applicable to all backup content; encryption provides comprehensive protection regardless of data type.
