CompTIA Server+ (SK0-004) — Question 19

An administrator wants to ensure a server OS and data can be recovered in case all the server's hard disk drives fail simultaneously. Which of the following backup types must be implemented to meet the requirements?

Answer options

• A. Full backup
• B. Differential
• C. Incremental
• D. Bare metal

Correct answer: A

Explanation

A Full backup is essential as it captures the entire server OS and all data in one go, allowing for complete restoration after a total disk failure. Differential and Incremental backups only save changes made since the last backup, which would not suffice for a complete recovery in this scenario. Bare metal restores are useful for restoring to new hardware but still require a full backup to be effective.
