Backing up OneDrive for Business to a local drive isn’t directly supported by Microsoft, but there are some reliable ways to do it. For this Using a third-party Backup tool is efficient and effective.

It Offers a top-notch solution to transfer OneDrive files to Google Drive and OneDrive for business/home. It allows users to migrate data from OneDrive to OneDrive for business & Google Drive accounts. This utility migrates data from OneDrive to OneDrive for business & Google Drive accounts.
