I have checked the configuration settings for the folders I want backed up, and every one of them states ' ! It has been already registered.'
Following the path C:\Program Files > Buffalo > Backup Utility > SYSERRLOG, I find dozens of text files. Examples are :-

I have no idea what any of this means, and I certainly haven't been warned by the program that my files are not being backed up.
