Windows 10: Errors, Warnings: 8, 1

I'm getting the above error with the following in the log maybe once or twice a week after an overnight backup run.  Possibly associated with a Windws 10 update. Can anyone cast a light on this problem?

My guess is that Retrospect isn't run as administrator or run as a user without enough permissions.

It isn't clear if you run the backup once or twice a week and it happens every time. Or you run every night and it happens sometimes.
