5 reasons I back up data on Proton Drive instead of OneDrive
OneDrive is built into Windows and works well, but I switched to Proton Drive for encrypted backup and sharing.

Microsoft’s OneDrive is Windows's built-in data backup feature. It does a decent job and can be customized to work the way you want. You can control when it runs and the files it backs up. However, not all cloud backup solutions are created equal. Sure, OneDrive is convenient built-in cloud storage and sharing, but it may not be adequate if you are concerned more about privacy and security than convenience. However, you might want something with more privacy and security. Enter Proton Drive.
