Which statement about backups is true?

• A. Data is easy to restore and must be quick and easy to make
• B. Backups should be encrypted
• C. Backups should be kept on the same drive
• D. Backups are optional

Answer: (A)

Backups exist to let you recover data quickly after a failure, so the most important idea is that restoring data should be easy and the process of creating backups should be quick and straightforward. That is why the statement expressing that data is easy to restore and that backups should be quick to make is the best fit: it focuses on recoverability and practicality, which are the core goals of backing up. Encryption can be important for security, but it doesn’t address how usable the backup is for recovery. Storing backups on the same drive raises the risk that a single failure could ruin both primary data and backups. And saying backups are optional ignores their purpose in protecting you from data loss.
