High Availability and Disaster Recovery: Concepts, Design, Implementation - Hardcover

From the reviews:

"The book’s goal is to explain how to insure that IT services are available when needed, while keeping a good balance between their benefits and the cost to support them. ... the book has as its target audience several groups: architects and system developers/designers for DR/BC/HA solution specifications ... . The text is very clear, and includes 83 figures with detailed explanations, 26 tables, references, and a ten-page index. ... All of these features make the book very practical and attractive." (Mihail Sadeanu, ACM Computing Reviews, Vol. 49 (4), April, 2008)

Companies and institutions depend more than ever on the availability of their Information Technology, and most mission critical business processes are IT-based. Business Continuity is the ability to do business under any circumstances and is an essential requirement faced by modern companies. Both concepts - High Availability and Disaster Recovery - are realized by redundant systems. This book presents requirements, concepts, and realizations of redundant systems on all abstraction levels, and all given examples refer to UNIX and Linux Systems.
