# Will my Mac go to sleep in the middle of a backup?

Plugged in (or on a desktop Mac), a running backup keeps your Mac from dozing off through inactivity until it's done.

On battery, only a backup you start with **Back up now** does — and only while the battery is above 30%. Automatic and scheduled backups let your Mac sleep as it normally would, and simply carry on from where they stopped next time, so nothing is lost. That's why **Back up now** is the large button on every backup card.

Closing a MacBook's lid on battery still puts it to sleep; no app can prevent that.
