CompTIA Server+ (SK0-005) — Question 140

A change in policy requires a complete backup of the accounting server every seven days and a backup of modified data every day. Which of the following would be BEST to restore a full backup as quickly as possible in the event of a complete loss of server data?

Answer options

• A. A full, weekly backup with daily open-file backups
• B. A full, weekly backup with daily archive backups
• C. A full, weekly backup with daily incremental backups
• D. A full, weekly backup with daily differential backups

Correct answer: D

Explanation

Option D is correct because a differential backup saves all changes made since the last full backup, allowing for a quicker restore process. Incremental backups (Option C) require the restoration of multiple backup sets, making them slower. Open-file and archive backups (Options A and B) do not specifically address the need for quick recovery in this scenario.
