Incremental backup is the most space efficient because it only backs up the data that has changed since the last backup, whether that was a full backup or another incremental backup. This minimizes the amount of data that needs to be stored, making it more space-efficient than full or differential backups, which can include duplicate data or larger volumes of data.
