Many thanks for all your replies. Original question was:

The answer was that the remote machine saw the local one with a fully-qualified
host.domain name, rather than just the hostname. So the /.rhosts entry needed
to be changed from "hostname" to "hostname.domainname".

A lot of you asked why we are running backups as root rather than as an
unpriveleged user. Well, we are doing the latter now - the problem occurred on
a limited number of machines during an interim phase of moving between backup
