CompTIA A+ Core 2 (220-1102) — Question 249

An administrator is designing and implementing a server backup system that minimizes the capacity of storage used. Which of the following is the best backup approach to use in conjunction with synthetic full backups?

Answer options

• A. Differential
• B. Open file
• C. Archive
• D. Incremental

Correct answer: D

Explanation

The incremental backup approach is the most suitable as it only saves data that has changed since the last backup, thus conserving storage space. In contrast, differential backups accumulate changes since the last full backup, which can require more storage over time. Open file and archive backups do not focus on minimizing storage usage in the same way as incremental backups do.
