Called Geo-Zone-Redundant Storage (GZRS), it is available in preview for Azure Archive Storage customers. If you’ve never heard of Azure Archive Storage, it hosts redundancy options that users leverage to repair processes when data is corrupted. Among the redundancies are locally redundant storage (LRS), zone-redundant storage (ZRS), and Microsoft says more will be launched eventually. With GZRS, Microsoft says customers get a well-balanced option that blends availability, performance, and recovery. Users can leverage GZRS to read data even if a whole data region is unavailable. Microsoft also promises the following abilities:
Synchronously writing three replicas of your data across multiple Azure Availability Zones, such as zone-redundant storage today, protecting from cluster, datacenter, or entire zone failure. Asynchronously replicating the data to another region within the same geo into a single zone, such as locally redundant storage, protecting from a regional outage.

Microsoft also provides the following table to show storage comparisons across redundancies:
