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.

Book as title said provide introduction to HA and DR. Book is long we could find in there useful material, but it is not something exciting. Sometimes things are very strange written, that reading it couple times doesn't bring understanding of the topic. Sometimes information is repeated. It could be use as a textbook, but as a introduction is too much content. Basically it was ok, but I will be looking for better book, which will have the same content written in more light style and maybe on less amount of pages.
