Not sure I am following, but revisit the setting where you turned it off .... still off/disabled?
Guess one has to trust it's then off!
If you are not that trusting, then the only other way to check is via DB queries of related tables - mdl_task_schedules? Have not had to do so. If autobackups is off, then there won't be any activity in moodledata/temp/backup/ I would think.
Sooooo .... ?????
Best Guess!
