This solution applies to all Barracuda Backup Servers.
When performing an Exchange Message Level Backup, you will be asked for your LDAP Base DN. This is the LDAP Base Distinguished Name of your Active Directory install. This is almost always based on your Windows Domain Name.
The DN for domain.local would be DC=domain,DC=local.
The DN for foo.domain.local would be DC=foo,DC=domain,DC=local.
