A cloud administrator needs to configure a backup solution that minimizes the daily backup window. The primary requirement is to only back up data that has changed since the previous day's backup operation. Which backup type meets this requirement?
Differential
Full
Incremental
Synthetic full
The correct answer is incremental backup. An incremental backup only copies data that has changed since the last backup operation of any type (full or incremental). This method results in smaller, faster backup jobs compared to full or differential backups. A full backup copies the entire dataset each time it runs. A differential backup copies all data that has changed since the last full backup. A synthetic full backup is a separate process where a new full backup is created from a prior full backup and subsequent incrementals.
