High Load problem - Help Required

["Dan Track" <dan track gmail com>]

Hi

I've got a server that as a constant load of 5.00. The problem is the
server isn't really doing anything. Its purpose is as a backup server
so it only does something in the evening. What I'd like is help in
developing a strategy, using various tools, to find out whats causing
the problem.

Many thanks for any help.
Dan
