If a storage account is configured to use RA-GRS or RA-GZRS, the file shares will be configured as GRS or GZRS.
If the primary region becomes unavailable for any reason, you can initiate an account failover to the secondary region.Īzure Files doesn't support read-access geo-redundant storage (RA-GRS) or read-access geo-zone-redundant storage (RA-GZRS). Within the secondary region, your data is copied synchronously three times. It then copies your data asynchronously to a single physical location in the secondary region. Geo-zone-redundant storage (GZRS) copies your data synchronously across three Azure availability zones in the primary region. Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region. This preview adds GRS and GZRS support for standard storage accounts that have the large file shares feature enabled. For protection against regional outages, you can configure your storage account for GRS or GZRS to copy your data asynchronously in two geographic regions that are hundreds of miles apart.
