Windows offers a few different ways to back up your files. The most common choice, especially for those who have an external hard drive, is to use File History. File History is the primary offline data backup tool for Windows 11. It allows you to automatically save data to a drive and restore it. It has some similarities with the Time Machine feature in Mac computers where you will be able to restore multiple previous versions of a document or file if it has accumulated changes over time. For example, on a Word document, that you've had several variations for, with File History you could restore to the first save, or even the third or fourth depending on how far back you need to go.
