If perl's gethostbyname() (ie: NS lookup) works, then that IP address
is used.  If not, then nmblookup is run.  So provided there is no
entry in /etc/hosts, nmblookup should be used to get the IP address.
That is then passed to ping.

You should run BackupPC_dump manually with the -v option to see
exactly which commands are run.
