Azure's premium storage option combining zone redundancy in the primary region with geo-replication to a secondary region. Offers the highest durability and availability by protecting against both data center and regional failures.
Azure GZRS is used for mission-critical data requiring maximum protection, surviving data center failures via ZRS and regional disasters via geo-replication.
GZRS is an Azure Storage redundancy option that combines zone redundancy in the primary region with asynchronous geo-replication to a paired secondary region. Other clouds offer multi-zone and multi-region replication, but there is no single, directly named equivalent that matches Azure’s specific “ZRS + geo-replication to paired region” packaging and behavior across all storage types.
