The second edition of Data Protection goes beyond the traditional topics including deduplication, continuous availability, snapshots, replication, backup and recovery, and explores such additional considerations as legal, privacy, and ethical issues. A new model is presented for understanding and planning the various aspects of data protection, which is essential to developing holistic strategies. The second edition also addresses the Cloud and the growing adoption of software and function as a service, as well as effectively planning over the lifespan of a workload what the best mix of traditional, and cloud native data protection services might be. Virtualization continues to present new challenges to data protection, and the impact of containerization is examined.
