CompTIA Server+ (SK0-005) — Question 179

Which of the following backup methods protects all the changes that have occurred since the last full backup?

Answer options

• A. Incremental
• B. Archive
• C. Differential
• D. Snapshot

Correct answer: C

Explanation

The correct answer is C, Differential, because it captures all changes made since the last full backup, allowing for a quicker restoration. Option A, Incremental, only saves changes since the last backup, making recovery more complex. Option B, Archive, is used for long-term storage and does not focus on changes since the last full. Option D, Snapshot, captures the current state but does not specifically track changes since the last full backup.
