PC Backup OneDrive

Try it!

You can back up your important folders on your PC (your Desktop, Documents, and Pictures folders) with OneDrive, so they're protected and available on other devices.

Important: If you're surprised that your files are saving to OneDrive, see Files save to OneDrive by default in Windows 10.

Select the blue cloud icon in the Windows notification area, select Help & Settings > Settings, then Backup > Manage backup.
Select the folders that you want to back up.
Select Start backup.
