Hi Timothy,
OneDrive for Business is not intended to be a server replacement, read the description from Microsoft, and that is very clear, the fact that people including partners such as you are trying to use it as such is the problem. Let me ask did you have your servers set to sync every file with your desktop? Most likely not, so why are people trying that with OneDrive for Business? Map a drive to it if you want to what is there, which is most likely how you did it with the server.
