System backup is essential in any enterprise—protecting data is equivalent to protecting the company or agency. Whether you have the task of putting together a backup and recovery system for your organization or your are thinking about how backup and recovery fits within the scope of total data availability, Implementing Backup and Recovery is an invaluable resource. This detailed guide takes you through the necessary steps of deploying services by showing you how to address the architecture, limitations, and capabilities of the existing network infrastructure.

After an introduction to backup and recovery in the enterprise, Little and Chapa give a tutorial on the components of backup. Then, using VERITAS NetBackup as an example, they show you how to install and configure a backup application, and how to customize services to meet customer needs. Throughout the book, the authors use real-life client situations to explain specific concepts. In addition, you’ll also learn:

  • The business and legal requirements of backup systems
  • VERITAS NetBackup’s tiered architecture and configuration elements
  • How to determine your need for additional backup services
  • What the future holds for backup and recovery

Acknowledgments

I want to first thank my wife, Nancy, for all her support during this long and sometimes arduous process. Thanks for doing all the driving so I could work on the book. We can't accomplish much without a supportive family behind us and I am no exception. My kids, Dan, Lisa, Jill, Jeff, and Amanda, have always been there as well as my parents, Ray David and Jeffie Little. Thanks to you all.

I would also like to give a special thanks to my co-workers Jim Coby and Mark Erickson who were there to help and also provided content when asked. I am sure my family and my co-workers were beginning to wonder if there really was a book. I guess this is the proof.

A special thanks also goes out to Dave High who was willing to review the chapters as I completed them and took the time from his own busy schedule to provide comments and feedback. This book would never even have happened without the support of Scott Tirrell and Brad Hargett who afforded me the time as needed. I would also like to thank the following VERITAS people who were willing to review parts of the book and offer comments: Danny Dunn, Erik Moller, Bill Drazkowski, Shawn Aquino, John Moore, Terry Noonan, Jim Olson, and Hector Herrero. Charlie Van Meter and Bob Santiago skillfully provided the figures, especially the better ones.

I would like to thank the staff at John Wiley & Sons for being patient with a beginning author and taking the time to help me through some of the rough spots. The original drivers behind this entire project were Paul Massiglia and Richard Barker. They are to be either thanked or blamed.

-David B. Little

To my parents for always believing that I could do anything I put my mind to, thanks mom and dad.

Thanks to Kevin Weiss, my friend and boss, and to everyone at DataStaff for their constant encouragement.

Thanks to Peter L. Buschman, friend and co-laborer in the field of backup storage management. Your keen insights continue to challenge me to think not only outside the box but to search for an entirely new box to explore.

Thanks to Paul Massiglia at VERITAS for his sage advice as a seasoned author and to Dave Little for asking me to jump on board with this project. It's been a great experience so when's the next one Dave?

Thank you must go out to Charlie Van Meter, VERITAS, and his team for taking our diagrams, pictures, and drawings and making us look good!

All the great folks at Wiley, thank you for allowing me this opportunity, especially to Adaobi Obi Tulton and Carol Long for challenging us to push forward! And Angela Smith for her diligence.

To the Starbucks in Lake Geneva, WI-many thanks! I did most of my writing after work in that little shop on a $1.83, venti coffee-no room, thank you very much. Thanks for putting up with me!

To my brother Joe, for helping me with the equations for the backup models and his all around support and prayer.

With great thanks to the many people at my church Redeemer PCA for their continued encouragement, support, and prayer through this project.

And with eternal thanks to my lovely wife Jill (I love you) for giving up so many evenings and weekends together so I could work on this book; and to our children, Ashley and Tyler (I love you two so much), who caught the writing bug and started a few of their own books while daddy was working on his.

There are many others who have helped me throughout my career, both personally and professionally, every one of them were instrumental in getting me to this point. Thanks to Kathy DeLeo, Jeff Gentges, Wendy Petty, Yuda Doron, Betty McGee, Craig Burdett, Bob Allums, Brian and Leslie Schwartz, Steve Alburty, and everyone else who has had an impact on my life.

Lastly, but certainly not least is my thanks to God; it's only by the strength of Christ that I was able to juggle so many things during this project and my busy life. Thank you.

-David A. Chapa
