The documentation is correct but incomplete.  You do not have to shut
down Tomcat; you have to shut down the instance of DSpace that you are
restoring.  If DSpace is the only application running on that Tomcat
instance, then it's easiest to shut down Tomcat; if not, there's no
need to bounce other applications along with DSpace.
