Data Protection: Ensuring Data Availability

by Preston de Guise (contributor)

This is the fundamental truth about data backup is dead.Or rather, backup and recovery, as a standalone topic, no longer has relevance in IT. As a standalone topic, it's been killed off by seemingly exponential growth in storage and data, by the cloud, and by virtualization.So what is data protection?This book takes a holistic, business-based approach to data protection. It explains how data protection is a mix of proactive and reactive planning, technology and activities that allow for data continuity. It shows how truly effective data protection comes from a holistic approach considering the entire data lifecycle and all required SLAs. Data protection is neither RAID nor is it continuous availability, replication, snapshots or backups--it is all of them, combined in a considered and measured approach to suit the criticality of the data and meet all the requirements of the business.The book also discusses how businesses seeking to creatively leverage their IT investments and to drive through cost optimization are increasingly looking at data protection as a mechanism to achieve those goals. In addition to being a type of insurance policy, data protection is becoming an enabler for new processes around data movement and data processing.This book arms readers with information critical for making decisions on how data can be protected against loss in the cloud, on-premises, or in a mix of the two. It explains the changing face of recovery in a highly virtualized data center and techniques for dealing with big data. Moreover, it presents a model for where data recovery processes can be integrated with IT governance and management in order to achieve the right focus on recoverability across the business.

Extremely thorough / comprehensive book on data protection. There are three definitions of data protection - 1) as a storage and recovery activity 2) as a security activity 3) as a privacy activity. The focus of the book is on the first activity.

Very focused on the business aspects - aware that price/cost is a consideration. Learned about data gravity (the more data there is, the greater likelihood that services and applications will be attracted to the data).

But generally, very dry and detailed with lots of ideas for a serious IT person. As a casual reader, some of the terms went over my head, but the book also does a good job at explaining concepts.

I liked the ending where he mentions that while we consider data from a business perspective, we must never lose sight of the personal aspect - eg in the energy sector, it can result in people losing power.
