Are you saying it starts up even after you've set it to off? That would be unusual. If you turn it off while it's already running, it might take a while to shut down. It has to get all its information and links in order before quitting. If it's a first backup, or a backup that has to copy a lot of stuff, it might take a long time. Another possibility is that your wireless link is weak or there is interference and you're getting a lot of dropped packets. That will slow it down quite a lot. I'd let it run overnight and do its thing then. I think a feature improvement would be the ability to set time-of-day ranges when Time Machine can be disabled.. -- Dennis Fazio
