I found it somewhere while googling, just to make it accept the code. If you look at my post you quote, I provided the link. I just google and cut and paste most of the time. 
However, I noticed later that image uploads were not necessary to make backups work. I still don’t know why one would use it. You really only need the backup. You do not need two buckets. I unchecked that part in the settings because I still had upload errors and images were not allowed by the users. unchecking that item fixed it. We have a small server group, so we should be fine for a long time.
