Chapter 3 Exercise 3

3. Using the Internet, find at least two software packages that will back up data across a LAN. Briefly explain how the software functions and what components need to be installed. Estimate the price of the software for a network of four servers and 100 clients.

Several backup packages exist. Most are relatively expensive. Examples include Arkeia, Dantzí Retrospect, Veritasí Backup Exec. Prices range from about $500 plus $50 per station and up. Retrospect multiserver appears to include the necessary licenses and costs about $1,000.
