You should limit administrator's permissions, if you haven't done that already. If you give your administrators permissions to do backups and set other administrator's permissions, then that can happen again. I would recommend you reading "Administrator accounts" section from this link to understand more what I'm talking about.
You can also see all administrators actions in ACP, because each of them is logged by the system. They should be available in "Tools & Maintenance" tab. You can see whether he did or didn't do a backup.
