Create a Time Machine backup

To create backups with Time Machine, all you need is an external storage device. After you connect the device and select it as your backup disk, Time Machine automatically makes hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months. The oldest backups are deleted when your backup disk is full.

Connect an external storage device

Connect one of the following external storage devices, sold separately. Learn more about backup disks that you can use with Time Machine.

  • External drive connected to your Mac, such as a USB, Thunderbolt, or FireWire drive
  • External drive connected to an AirPort Extreme Base Station (802.11ac model) or AirPort Time Capsule
  • AirPort Time Capsule
  • Mac shared as a Time Machine backup destination
  • Network-attached storage (NAS) device that supports Time Machine over SMB

Select your storage device as the backup disk

When you connect an external drive directly to your Mac, you might be asked if you want to use the drive to back up with Time Machine. Select Encrypt Backup Disk (recommended), then click Use as Backup Disk.

An encrypted backup is accessible only to users with the password. Learn more about keeping your backup disk secure.

  2. Click Select Backup Disk (or Select Disk, or Add or Remove Backup Disk):

Enjoy the convenience of automatic backups

After you select a backup disk, Time Machine immediately begins making periodic backups—automatically and without further action by you. The first backup may take a long time, depending on how many files you have, but you can continue using your Mac while a backup is underway. Time Machine backs up only the files that changed since the previous backup, so future backups will be faster.

To start a backup manually, choose Back Up Now from the Time Machine menu in the menu bar. Use the same menu to check the status of a backup or skip a backup in progress.

If you used Time Machine to create a backup of your Mac, you can restore your files from that backup or a local snapshot on your startup disk. You might want to restore your files after the originals were deleted from your Mac, or the hard disk (or SSD) in your Mac was erased or replaced, such as during a repair.

Restore from a Time Machine backup

When you restore from a Time Machine backup, you can choose to restore all your files, or restore both the Mac operating system (macOS) and all your files.
