I think that this book is excellent. Backup and recovery can be hard to understand at times, especially for those who are new to it. It is a great book that is all hands on, and that's the way you learn B/R, not just by reading. If you have a little bit of knowledge of B/R then this book will really help you a lot. I know people complained about the typos, but that is not that big of an issue, plus they already have an errata out for it. The only downside I guess is that everything is done using Oracle 8i and some commands are different. But if you combine this book with the Oracle9i Backup and Recovery documentation then you're all set! I think it explains things very well and makes you do things so you can see what exactly is going on. I would definitely recommend this book to anyone who has a little knowledge of Oracle B/R but would like to put that knowledge into practice. I want to give it 4.5 stars because of the minor typos and using 8i, but can't :) BUY THE BOOK!
Good Luck!!
