Reliability in Microsoft Purview
This article describes reliability support in Microsoft Purview for governance experiences, and covers both regional resiliency with availability zones and disaster recovery and business continuity. For a more detailed overview of reliability principles in Azure, see Azure reliability.
Availability zone support
Availability zones are physically separate groups of datacenters within each Azure region. When one zone fails, services can fail over to one of the remaining zones.
For more information on availability zones in Azure, see What are availability 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 availablility-zone support in a limited number of regions. This partial availability-zone support covers experiences (and/or certain functionalities within an experience).
- Zone availability might or might not be available for Microsoft Purview governance experiences or features/functionalities that are in preview.
Supported regions

Disaster recovery and business continuity
Disaster recovery (DR) is about recovering from high-impact 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 DR plan and an application design that actively supports DR. Before you begin to think about creating your disaster recovery plan, see Recommendations for designing a disaster recovery strategy.
When it comes to DR, Microsoft uses the shared responsibility model. In a shared responsibility model, Microsoft ensures that the baseline infrastructure and platform services are available. At the same time, 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 are 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 DR and you can use service-specific features to support fast recovery to help develop your DR plan.
Important
Today, Microsoft Purview doesn't support automated disaster recovery. Until that support is added, you're responsible to take care of backup and restore activities. You can manually create a secondary Microsoft Purview account as a warm standby instance in another region. Note that this standby instance in another region would not support Microsoft Purview Data Governance Solution. Today, it only supports Azure Purview solution. We are working on adding DR support for Microsoft Purview Data Governance Solution.
