Hi Michael, OpenDNS by default returns their own internal server addresses for any queries that don't resolve to a public IP. They do this so that they can serve up their own search page (with ads, of course) when someone mistypes a domain name. This behavior breaks a lot of stuff, including, in this case, your backups.
If you have an actual account set up with OpenDNS, I think you can disable this feature. Otherwise, use Google's public DNS: 8.8.8.8 and 8.8.4.4, which do not break DNS. Hope this helps, - R.
