I was assuming the suggestion was to rsync the source to the temp
while the destination still exists, before rsyncing or mv'ing over
the top of it. Total of 3 copies (temporarily) rather than 2.
Then, it's different. But in your scenario you would probably want
to take down whatever "service" relies on the destination dir while
the copy is in progress.
