Block-level backup and Microsoft OneDrive

I setup backup plans for NAS and OneDrive.
There is a difference when coming to “Advanced Mode”.
For NAS I can select “Use block level backup”.
For OneDrive this option is missing.

Do I overlook something here or is OneDrive not ready for block-level backup?
Thanks
Andreas

[reply=“Andreas Wagner;d615”] Yeah, that’s OneDrive’s API limitation. All consumer storage providers like Google Drive and Amazon Cloud Drive have shortcomings like that.
