But doesn't this get done at the link stage, not the backup stage? I
didn't think that the "link running" part even got counted in the backup

In my case, this is well after the first (or first 100) backups...

I'm going to have to test this... but I really don't like the fact that
with checksum caching a file corrupted on the backup server will remain
undetected--until the user tells me so when I restore it... :(
