I have set a daily backup schedule, but Windows Server Backup only keeps one full backup. after the first backup, the next backup completes very quickly. I suppose it is doing differential backup. every time a scheduled backup completes, I only find one full backup on the folder while there is plenty of free space. PS: I am running Windows Server 2016 Preview 3. I tried to restore the previous version of backup, it only restore the latest backup. SEE the screenshot.
