Udemy – Backup & Disaster Recovery: For Beginners

Data loss, system outages, ransomware attacks, and unexpected disasters can stop an organization in its tracks. Whether caused by hardware failure, human error, cyberattacks, or natural disasters, the ability to recover quickly and reliably is a critical IT skill. This course provides a structured, practical, and beginner-friendly introduction to Backup, Disaster Recovery, High Availability, and Business Continuity—built around real-world practices used in modern IT environments.

You’ll begin by understanding why backup and disaster recovery matter, exploring common causes of data loss and learning essential terminology such as backups, disaster recovery, business continuity, RPO, and RTO. These foundations help you think like an IT professional when assessing risk, impact, and recovery requirements.

From there, the course dives into core backup technologies and strategies, including full, incremental, and differential backups; onsite, offsite, hybrid, and cloud backup models; and how to select the right strategy based on business needs, cost, and recovery objectives. You’ll learn how backup frequency, retention, and storage choices directly affect data loss and downtime.

You’ll then explore backup planning and policy design, covering scheduling, automation, monitoring, retention policies, compliance considerations, and documentation. These lessons show how to move beyond “having backups” to running a reliable, auditable, and scalable backup operation aligned with business requirements.

The course also provides in-depth coverage of modern backup tools and technologies, including backup software, storage media (disk, tape, and cloud), snapshot technology, application-aware backups, infrastructure and configuration backups, deduplication, and backup security. Each topic explains not only what the technology is, but why it matters and how it fits into a complete data protection strategy.

High Availability and Redundancy concepts are introduced to show how systems are designed to stay online during failures. You’ll learn about network, server, and storage redundancy, and clearly understand why technologies like RAID improve availability—but are not backups—eliminating one of the most common and costly misconceptions in IT.

A strong focus is placed on testing and validation, teaching you how to verify backups, perform restores, troubleshoot failures, and measure recovery results against RTO and RPO targets. Real-world recovery scenarios—including hardware failures and ransomware incidents—demonstrate how backup, security, redundancy, and disaster recovery planning work together under pressure.
