We currently have a script that uses robocopy to copy changes from the source to the destination directory, then runs another robocopy with /purge to remove everything from the destination that doesn't exist on the source. The objective is to have the destination(s) exact copies of the source, with nothing being sync'd back to the source.

So the destination will be an exact copy of the source.

Sync Files from right to left works in most cases, but I've found two cases where it does not work as I am wishing it to.:
• Empty directories that don’t exist on the source are not deleted from the destination.
• Files created on the destination side ( and do not exist on the source side) are not deleted when the task runs.
