When Time Machine is turned on, it automatically backs up your Mac and performs hourly, daily, and weekly backups of your files. ... That way, if anything ever happens to your internal disk or to your Mac, you can restore your entire system to another Mac. Connect an external hard disk to your Mac and turn the disk on.
Is Time Machine a true backup?
Time Machine performs a full backup of your Mac when it is first set up. This initial backup can take some time, so be patient and allow it to finish. Once the first backup is complete, Time Machine checks your Mac for new, changed, and deleted files once every hour.
