Reliability in Microsoft Purview

This article describes reliability support in Purview for governance experiences. It covers both regional resiliency with availability zones and disaster recovery and business continuity. For a more detailed overview of reliability principles in Microsoft Azure, see Azure reliability.

Availability zone support

Availability zones are physically separate groups of datacenters within an Azure region. When one zone fails, services can fail over to one of the remaining zones.

Microsoft Purview makes commercially reasonable efforts to support zone-redundant availability zones, where resources automatically replicate across zones, without any need for you to set up or configure.

Prerequisites

• Microsoft Purview governance experience currently provides partial availability zone support in a limited number of regions. This partial availability zone support covers experiences and certain functionalities within an experience.
• Zone availability might or might not be available for Microsoft Purview governance experiences or features and functionalities that are in preview.

Disaster recovery and business continuity

Disaster recovery refers to practices that organizations use to recover from events such as natural disasters or failed deployments that result in downtime and data loss. Regardless of the cause, the best remedy for a disaster is a well-defined and tested disaster recovery plan and an application design that actively supports disaster recovery. Before you start creating your disaster recovery plan, see Recommendations for designing a disaster recovery strategy.

For disaster recovery, Microsoft uses the shared responsibility model. In this model, Microsoft ensures that the baseline infrastructure and platform services are available. However, many Azure services don't automatically replicate data or fall back from a failed region to cross-replicate to another enabled region. For those services, you're responsible for setting up a disaster recovery plan that works for your workload. Most services that run on Azure platform as a service (PaaS) offerings provide features and guidance to support disaster recovery. Use service-specific features to support fast recovery to help develop your disaster recovery plan.

Important

Classic Microsoft Purview doesn't support automated disaster recovery. You're responsible for backup and restore activities. You can manually create a secondary Purview account as a warm standby instance in another region. This standby instance in another region doesn't support Microsoft Purview data governance.
