If you are currently running a storage account, in GRS, you can now do a failover, manually, to switch from the primary region to the secondary. From the 17th of June, this feature is now generally available: https://azure.microsoft.com/en-us/updates/azure-storage-account-failover-ga/

To start, be sure to have a storage account, with one of the following SKU:

  • Geo-redundant storage (GRS) or read-access geo-redundant storage (RA-GRS)
  • Geo-zone-redundant storage (GZRS) or read-access geo-zone-redundant storage (RA-GZRS)

To verify this information, go into your storage account, and you will have the information directly here, or in the Geo-Replication part:

We can see available regions on the Overview panel:

To do the failover, it’s very simple, you have 3 possibilities:

  • Through PowerShell:

  • Through Azure CLI:

Through the portal, in your storage account, click on Geo-Replication and on Prepare for failover:

Here, we have some information regarding the failover. Write yes to start it:

When the failover is finished after few minutes, the principal region is now North Europe:

We can see that the DNS name to access this storage account is the same, but the IP changed:

The storage account moved to LRS also. You can put it back to GRS, that we will re-replicate datas in West Europe:
