Raise an error if file exists on destination

The -i <--itemize-changes, output a change-summary for all updates> may do what you want.

However, my understanding for files which are detected to be the same in the source(s) and the destination will not be updated / overwritten. Perhaps someone else on the rsync mailing list may be able to clarify this point or answer your question more appropriately.
