What is a backup?

What is a backup?

• A. The process of copying data
• B. A virus that replicates itself
• C. A plan to organize files
• D. A security feature protecting data

Answer: (A)

Backing up data means making extra copies of important files so you can recover them later if something goes wrong, like hardware failure, accidental deletion, or a malware attack. The essential idea is to preserve a duplicate of your information in a separate place so you can restore it to its previous state. This is best described by the option that says copying data, because it directly captures the action involved in creating a backup—you duplicate the data and store that copy somewhere safe. The other ideas refer to different concepts: a virus that copies itself is malware, a plan to organize files is about sorting or cataloguing data, and a security feature protecting data covers protections like encryption or access controls rather than the act of making duplicate copies. Backups are a practical method for data recovery, often stored on an external drive or in the cloud and can include multiple versions over time.
