# What happens if my Mac is asleep when a scheduled backup is due?

It backs up **once** when it's next able — not once for every slot it missed. So after a week away you get one backup when you're back, not a burst of seven.

If the Mac is shut down or Storage Studio isn't running, the app also does a catch-up when it next opens, finishing anything that didn't complete.
