I guess? Don't know how I'd check that.

It is empty.

Nightly cleanup removed 2831 files of size 28.75GB (around 9/19

There are 172 hosts that have been backed up, for a total of:
318 full backups of total size 2569.41GB (prior to pooling and
compression),
4687 incr backups of total size 8298.06GB (prior to pooling and
compression).

That's a 2% difference; min is 3055GiB vs ~3800GiB, which is a *20*%
difference. 10x more different. Seems a lot.

Good point. That might do it.
