Your question makes no sense. The subject is "linux backup tools", and here you're asking about either Red Hat Linux, or Nagios. Which is it??
If you'd like information about Nagios, visit their website. There are many, MANY backup solutions for Linux, both commercial and free, but without knowing your requirements, we can't suggest one over the other.
