What are the key principles of data recovery approaches, and how do they differ from traditional backup methods?

Expert Solution
Step 1: Introduction

Data recovery and traditional backup methods serve different purposes but are closely related. The key principles of data recovery approaches prioritize rapid recovery, point-in-time restoration, and data granularity to ensure minimal downtime and data loss. Traditional backup methods, on the other hand, focus on periodic backups, often with less granularity, and rely on physical media for data storage, which can result in longer recovery times. The choice between these approaches depends on the specific needs and priorities of an organization in terms of data protection and recovery. Many businesses today use a combination of both strategies to ensure comprehensive data protection.
