Comment 11 for bug 1747646

This bug seems to not have been fixed yet. Nobody seems to have posted its solution on the internet.
Description : I have a weekly backup scheduled. I do this on my google drive of my gmail account.

The backup happens for about 10 minutes. I'm unable to unmount my google drive from my computer this time and the computer tells me that some operations are keeping th volume busy.

Then I get this error message:-
This has been happening since 1 month continously and everytime I get this error message

Giving up after 5 attempts. Error: gdata-service-error-quark: Authentication required: {
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "authError",
    "message": "Invalid Credentials",
    "locationType": "header",
    "location": "Authorization"
   }
  ],
  "code": 401,
  "message": "Invalid Credentials"
 }
}
