Back up your Mac

Backing up your Mac is simple and important. We recommend it for everyone.

Make automatic backups

Your Mac comes with software to make backing up simple. Just turn on Time Machine and connect an external drive. Time Machine makes automatic backups of everything so you can recover individual files or your entire system from your backups.

Other backup methods

How much space do I need for a backup?

To see the size of a specific file or folder, click it once and then press Command-I. To see storage information about your Mac, click the Apple menu in the top-left of your screen. Choose About This Mac and click the Storage tab. For Time Machine backups, it's good to use a drive that has at least twice the storage capacity of your Mac.
