![]() ![]() For example, a new version of your application might inadvertently make a change to the data that causes it to break. In addition to the possibility of platform failures, problems with a customer application or data can occur. Although your VMs and disks are normally protected from localized failures, additional steps are necessary to protect your workload from region-wide catastrophic failures, such as a major disaster, that can affect your VM and disks. Major disasters can result in failures or the inaccessibility of many storage servers or even a whole datacenter. The Azure platform is designed to be resilient to these failures. Such isolated hardware component failures can happen during normal operations. Local failures can include problems with an Azure Storage server machine that stores part of the data for a virtual disk or failures of an SSD or HDD on that server. The Azure platform uses various methods for redundancy and fault tolerance to help protect customers from localized hardware failures. We then review possible solutions for the DR of IaaS disks. We also show several examples of workload scenarios where different backup and DR considerations can apply. We then discuss the disaster scenarios not fully covered by the built-in capabilities. This document covers unmanaged disks, or page blobs.įirst, we cover the built-in fault tolerance capabilities in the Azure platform that helps guard against local failures. ![]() This article explains how to plan for backup and disaster recovery (DR) of IaaS virtual machines (VMs) and disks in Azure.
