Based on the information you've provided, you've tried multiple methods to remove the reanalysis points from OneDrive, but it seems that these methods didn't work. For your issue, you can try the Reset OneDrive method to troubleshoot the application: Reset OneDrive - Microsoft SupportAlso make sure you have permission to delete these folders. You can refer to this link to modify Windows folder permissions:How to take ownership of a folder - Microsoft Community Finally, if the problem persists, would you be willing to provide us with a specific online backup provider so that we can further troubleshoot the issue.
I wish you good health and all the best
