Summary
This chapter examined a number of options open to an administrator looking to provide data security and hardware redundancy for the network. Through the use of a regular backup plan, the installation of a UPS, and the implementation of a fault-tolerant disk scheme, you can help to ensure that your network will run as efficiently and safely as possible. Remember that there is no particular formula to use here; rather, you should follow a process of weighing costs against benefits. In the end, you want to provide the highest degree of safety for your critical data that you can achieve given your budget. Now test your knowledge of this chapter’s topics by completing the exercise and answering some review questions.
