> Chapter 105 of the Courseiva AZ-900 curriculum — https://courseiva.com/learn/az-900/azure-backup

**Official objective:** 2.1 — Azure Architecture Services

## Introduction

This chapter covers Azure Backup. AZ-900 tests under 2.1.

## A Backup Tape

Businesses keep backup tapes in case data is lost. Azure Backup automates this: periodic backups stored in Azure, recoverable if data is lost or corrupted.

## Core explanation

Backup automates periodic backups of on-premises and Azure resources, storing them securely in Azure. Backups are available for restore if needed.

## Real-world context

Daily backups of VMs are retained for 30 days; if a VM is accidentally deleted, it's restored from a recent backup.

## Exam focus

Objective 2.1 expects understanding of automated backups.

## Step by step
