Azure Storage strives to provide you with effective disaster recovery offerings, and we are excited to introduce our new feature, planned failover (in preview) for Azure Storage. Planned failover provides the ability to failover a storage account while maintaining geo-redundancy, with no data loss or additional cost. You will no longer need to reconfigure geo-redundant storage (GRS) after your failover operation. Planned failover enables you to effectively swap your primary and secondary endpoints while your storage service endpoints are available. Once the planned failover is complete, all new writes will be directed to the region that was previously your secondary region, which becomes your new primary region.
There are multiple scenarios where planned failover can be utilized including planned disaster recovery testing, a proactive approach to large scale disasters, or to recover from non-storage related outages.
