Backup Files Using Windows 10 File History (Backup Settings) 1. Open the start menu, and begin typing 'Backup Settings'. Select the first result shown below. 2. In the window that opens, click 'Add a drive', and select the drive where you would like to store your backed up files. 3. This will set File History to automatically back up your files indefinitely. If you'd like to make changes to the backup, click 'More options'. 4. In the Backup Options window, changes can be made to when files are backed up, how long the backups are kept, and what folders you would like to include in the backup. IF you decide you would like to use a different drive, or just want to cancel the backup altogether, scroll down to the bottom and select Stop using drive.
