There are different ways to back up your data, but one of the most convenient and reliable methods is to use Time Machine.

To use Time Machine, you need to have an external hard drive or a network device that has enough storage space for your backup. You also need to connect it to your Mac and format it as Mac OS Extended (Journaled) if it is not already. Then, you can open the System Settings app and click Time Machine.

You can turn on Time Machine and select your backup disk. You can also click Options to customize your backup settings.
