The lack of information is error message is not necessarily down to a "software developer attitude"; it is more likely that they have recognised that an error has occurred but, without an in depth knowledge of Google Drive, they display what little information that they have.

Anyway, Mike is not like  a "typical software developer".

While you wait for him to respond, I suggest you perform a local backup on your device and try manually transferring that to Google Drive. Should that fail to transfer, you have an issue outside of MS and, if it suceeds, you do at least have a backup there.
