Microsoft’s cloud storage service, OneDrive, can back up your personal and work files online. It’s built into Windows 10. With it you can sync files on your Windows 10 PC to the cloud and to your other Windows PCs, smartphone or tablet (with the OneDrive app for Android or iOS installed on either). It can even sync your cloud files to your Mac (via the OneDrive desktop app).
