Preparing for Disaster Recovery

In organizations the janitors have keys everywhere and the presidents have money. System Administrators usually get keys, a cut of the money, and passwords to the servers. From this it looks like the administrators have everything. There are reasons for this. With the keys you can come in anytime to fix things. With passwords you can work anywhere, and with the cut of money you can order the parts to give yourself more work. In this chapter we will cover some of the activities that system administrators might have to do in Linux. I will also give you an overview of the rest of the book and how it ties in with Linux administration.
