Azure Geo and Zone Redundant Storage (GZRS) helps customers achieve higher data resiliency by doing the following:
- Synchronously writing three replicas of your data across multiple Availability Zones (like ZRS today) protecting from cluster, datacenter or entire zone failure.
- Asynchronously replicating the data to another region within the same geo into a single zone (like LRS today) protecting from a regional outage. In the event of a regional failure you can use Read Access Geo and Zone Redundant Storage (RAGZRS) to continue having read access. For read and write access you can failover to the secondary region.
