This chapter covered the tools for handling Mac OS X backups and security. We started with some GUI backup and recovery tools, including Mac OS X's Time Machine, CCC, SuperDuper, and Mozy. Then we looked at two common command-line tools that are handy for backups: dd and rsync.
In the security discussion, we kept it simple and stuck to the built-in Apple firewall tools. You learned about the options available through Mac OS X preferences, the ipfw firewall, and WaterRoof, a front end for ipfw.
