Lab Activity

LVM Disaster Recovery

Learn to manage disaster recovery using LVM: from creating logical volumes to performing backups and restoring data after failure.

About This Lab

In this lab, you will simulate a real-world disaster recovery scenario by practicing backup and restoration of data from a Logical Volume. You will learn how to create and manage logical volumes, back up the data, simulate data loss, and restore everything to its original state. This process is crucial for understanding how to protect data and ensure business continuity in the event of a failure.

What You Will Learn

How to create and manage Logical Volumes using LVM.
The process of backing up data from logical volumes with the tar command.
How to simulate a disaster by removing and recreating logical volumes.
How to restore data from backups, ensuring minimal downtime.
How to ensure data persistence and recoverability in a production environment.

Why Learn This Lab?

Data recovery is one of the most critical tasks for system administrators, especially when dealing with data loss scenarios. Understanding how to properly back up and restore data on Logical Volumes is essential for maintaining system integrity and minimizing data loss risks. This skill is vital for real-world IT environments where data protection and disaster recovery plans are essential.

Who Should Take This Lab?

This lab is ideal for:

RHCSA and RHCE certification candidates who need to understand advanced LVM management and disaster recovery.
Linux system administrators responsible for data backup and recovery processes.
IT professionals looking to enhance their knowledge of disaster recovery and data protection in Linux environments.
