Scrub errors

Thanks for the pointer.  I was able to find the location of the errors.  Turns out I have one pretty messed up share.  It contains files that were deleted from the primary system some time ago and not some that were added, even though the log shows the incremental rsync backups completed just fine.  It appears rsync was not identifying there were any changes.  It appears that this happened some time before the previous scrub, so it's also concerning that nothing showed up in the main log.  There probably are entries in the downloaded logs, but who looks at those except when something else points top a problem?

The scrub had also ground to a crawl, so I stopped it.  I've renamed the old share and created a replacement, with the backup now ongoing.  Once that completes, I'm going to delete the old share; and I hope that doesn't give me any issues.
