Using Time Machine
Back Up & Restore
The Time Machine backup utility is a very important part of the macOS
operating system. It creates incremental backups of your files to a specified
location, such as an external hard drive. These files can later be browsed and
restored by running the Time Machine application.
(^1)
Connect an external hard drive, via USB, FireWire or
Thunderbolt, to your Mac. It should be at least the size
of your Mac’s hard drive. The larger the drive, the further back
in time you will be able to store backups. Now open System
Preferences and click on Time Machine in the bottom row.

If you choose to reformat your disk, all data currently on
the drive is wiped. You might get a pop-up asking if you
would like to use the connected drive with Time Machine. Click
Decide Later so the Time Machine settings can be configured
to your requirements first.

Once your external drive is connected correctly, you
can always access Time Machine by opening System
Preferences from Launchpad or the Applications folder on
your Mac. Check the Show Time Machine in Menu Bar box
and you can also access it from the menu bar.

Click the Select Disk... button and you will be presented
with a window listing your connected drives. Select the
drive on which you would like to store your backups. If your
external drive isn’t already formatted as ‘Mac OS Extended
(Journaled)’, Time Machine invites you to erase and reformat it.
