I have sent these files.
Regarding settings, here's what I said above. There's really nothing else to it than this.
I don't think it makes any difference, but so you understand my environment, I have two fast drives that act as my main drives, then a third, shingled drive that acts as the duplication drive. So, under Drive Use Limiter the two, fast 4TB drives are set up only for Unduplicated. Then, the 8TB shingled drive is set only for Duplicated.
