A company is implementing a new data protection policy and requires all critical data to be saved daily. They have designated an incremental backup strategy, which captures only the changes made since the last backup.
Which of the following describes the primary benefit of using this type of backup?
It provides a complete copy of all data at every backup instance.
It is useful for backing up data that rarely changes.
It significantly reduces backup time and storage requirements.
An incremental backup saves only the data that has changed since the last backup, so each backup job is faster and consumes less storage than a full or differential backup. Because the backup window is shorter and the amount of data written is smaller, it is well-suited to daily protection of systems with frequent changes. (A drawback is that a full restore is slower, because you must apply the last full backup plus every incremental set in order.)
