Once I got rid of those, it started behaving as expected, both from the script and directly from the command line. I noticed that it seemed to be deleting every file in the destination before sync'ing from the target. Even changing the --delete flag to --delete-after didn't change this. It's not ideal, but it's much better than re-sync'ing all of the data on every backup. Thanks for the suggestions. _KJH
