Hi @Grey_Matter-One ,
You could take a try to sync files from your personal OneDrive to the business OneDrive with steps below:
when a file is created or modified in the personal OneDrive, you could check if the file exists in the business OneDrive, if yes, update the file, if not , create the file in the business OneDrive.
When a file is deleted in the personal OneDrive, check if the file exists in the business OneDrive, if yes, delete the file, if not, do nothing.
You should also create the flow to sync files from your business OneDrive to the personal OneDrive with the same steps.
And you need to prevent the loops between the flows for file updating
