Public Preview: Azure Files geo-redundancy for standard large file shares

We’re excited to announce Azure Files geo-redundancy for large file shares is now in public preview for standard SMB file shares.


Azure Files has supported large file shares for several years, which not only provides file share capacity up to 100TiB but improved IO operations per second (IOPS) and throughput as well. Large file shares are widely adopted by customers using locally redundant storage (LRS) and zone-redundant storage (ZRS) but has not been available for geo-redundant storage (GRS) and geo-zone redundant storage (GZRS) until now.


Geo-redundancy is critical for meeting various compliance and regulatory requirements. Geo-redundant storage asynchronously replicates to a secondary region and if the primary region becomes unavailable, you can initiate a failover to the secondary region.


Choosing between performance and scale or geo-redundancy is no longer necessary! You can now use geo-redundancy and enable large file shares on new and existing storage accounts to significantly increase your standard file share capacity and performance limits while benefiting from geo-redundancy:
