Now munin is back, we can see the effect of the backups on eu0 (about 6am):
Now you can see there is a shed load of iowait going on there when the
backup happens. But interestingly there is a lot of iowait all the
time - or more than I have seen with other hosts.
Is this host running off tape or something? Anyway I really don't
think it is an appropriate backup host!
Is it possible there is some disk misconfiguration going on here?

We probably need a different thread for this discussion.
