Which term saves additional physical copies of the data?

• A. Backup
• B. Recovery
• C. Authentication
• D. Access Privileges

Answer: (A)

The main idea here is data redundancy through backups—the practice of saving extra copies of data so you can recover it if the original becomes lost or damaged. A backup is a separate copy stored away from the primary data, often on a different device or location, to protect against hardware failures, accidents, or disasters. This differs from recovery, which is the process of using those backups to restore data after a loss. It also differs from authentication (verifying identity) and access privileges (controlling who can access data). In short, backups specifically address creating and preserving additional copies to ensure data can be restored when something goes wrong.
