You can back up your Windows computer using "File History" or "Backup and Restore (Windows 7)".
If you are on Windows 11, open "Control Panel -> System & Security -> File History" for the first option. Click the "Turn on" button if your backup drive already shows up in the list. Next, go to "Advanced Settings" and select how often "File History" should create an incremental backup of your files.
On Windows 10, go to “Settings -> Update & Security -> Backup” to find "File History."
As for the second option, it will create an image backup. Find it by going to "Control Panel -> System & Security -> Backup and Restore (Windows 7)" in both OS versions.
