To use Time Machine, you only need an external storage drive such as a USB, an SSD card, or any storage device that can be plugged into your Mac. And if you’re backing up data from several Mac computers, there’s no need to use a separate device for each Mac, provided it has enough space for all files. In case you’re getting a new Mac, you can easily copy all your files from your old computer to the new one, with your settings, files, and folders intact. This is because Time Machine stores multiple copies of the file from days 1 to 5.

So if you need to retrieve a version of a file with changes made on day 2, you can do so even after you’ve made several changes on the file from days 3 to 5. Time Machine has periodically created backups of the changes you’ve made every day. Let’s say you’ve been working on a file for five days.

Your Mac’s Time Machine should be your primary backup system.
