The only thing that seems slightly strange in the graphs is the load average
going to 12 as the backups start and staying there a couple of hours. Normally
that's the average number of 'other' processes that are waiting for CPU but
otherwise runnable (i.e. not themselves blocked on i/o). Do you have other
things running that should be active at this time? Idle daemons wouldn't count
because they should be blocked waiting for input.
