CompTIA Security+ (SY0-601) — Question 662

An organization wants to minimize the recovery time from backups in case of a disaster. Backups must be retained for one month, while minimizing the storage space used for backups. Which of the following is the best approach for a backup strategy?

Answer options

• A. Full monthly, incremental daily, and differential weekly
• B. Full weekly and incremental daily
• C. Full weekly and differential daily
• D. Full daily

Correct answer: C

Explanation

The correct answer is C, as a full weekly backup combined with differential daily backups allows for quicker recovery times while minimizing storage use. This method ensures that only changes since the last full backup are stored daily, unlike incremental backups which would require all previous incremental backups to restore, leading to longer recovery times. Options A, B, and D do not balance recovery time and storage efficiency as effectively as option C.
