CompTIA Server+ (SK0-005) — Question 128

A backup application is copying only changed files each time it runs. During a restore, however, only a single file is used.

Which of the following backup methods does this describe?

Answer options

• A. Open file
• B. Synthetic full
• C. Full incremental
• D. Full differential

Correct answer: B

Explanation

The correct answer is B, Synthetic full, because this method combines previous incremental backups into a single full backup, allowing only the latest file to be restored. Options A, C, and D do not accurately describe the scenario since Open file does not relate to incremental backups, Full incremental would require multiple backups to restore, and Full differential would require both the last full backup and the latest differential backup for restoration.
