How Do You Backup A Mac?

What is the best way to backup my MacBook Pro, MacBook Air, or iMac?

To do so, the best and the easiest way is to use Time Machine. For that, you need to:

1. Connect an external storage device to your Mac like a USB or NAS that will store the original file copies.
2. Connect to stable Wi-Fi.
3. Complete the Time Machine Setup.
4. Transfer the files from your device to the external storage device.

And that’s it. Your files in Mac are backed up.
