You probably have some outside service providing DNS for your domain 
with the relevant public addresses while the machines sit behind a NAT 
router and need to refer to each other with private addresses.  The 
generic solution is to add your own DNS server(s) on the private side 
that all of your LAN machines use.  Configure it as primary for your 
domain and for the reverse lookups of your private address ranges - but 
don't register it as a public server.  That way outside lookups will get 
the usable public addresses only, but inside you will see the whole 
private range.  If that's too much trouble, just add the entries you 
need for backuppc to work in it's /etc/hosts file.   The quick fix for 
dhcp-assigned addresses is to configure the dhcp server to always give 
the same IP to the same MAC addresses.  Even cheap home routers normally 
have this as a setup option.
