CompTIA Server+ (SK0-004) — Question 6

An administrator needs to back up changed files only and has time constraints on the back up window. Which of the following is the BEST choice for a backup strategy?

Answer options

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

Correct answer: A

Explanation

The correct answer is A, Differential, as it backs up all the changes made since the last full backup, which is efficient in terms of time. Option B, Snapshot, generally captures the current state of a system, while C, Full, backs up all files, taking more time. Option D, Incremental, backs up only changes since the last backup, but requires all previous backups to restore, making it less optimal given the time constraints.
