CompTIA Cloud+ (CV0-003) — Question 41

An administrator needs to back up all the data from each VM daily while also saving space. Which of the following backup types will BEST fit this scenario?

Answer options

• A. Differential
• B. Incremental
• C. Synthetic full
• D. Full

Correct answer: B

Explanation

The Incremental backup method is the best choice here because it only saves the data that has changed since the last backup, thus using less storage space. Differential backups would store all changes since the last full backup, leading to larger storage needs over time, while Full backups require the most space as they back up all data every time.
