Windows - Back Up Documents, Desktop, Pictures Folders

Microsoft does not currently provide an automatic way to back up the Mac Desktop or Documents folders located on the Mac hard drive. Any files stored on the hard drive are at risk for data loss should the hard drive crash. It is recommended that you store all important files in your OneDrive and create desktop shortcuts to the OneDrive folders for easier access.
