- **Geo-redundant storage (GRS)**: With GRS, you have two regions, a primary region and a secondary region. Files are stored three times within an Azure storage cluster in the primary region. Writes are asynchronously replicated to a Microsoft-defined secondary region. GRS provides six copies of your data spread between two Azure regions. In the event of a major disaster such as the permanent loss of an Azure region due to a natural disaster or other similar event, Microsoft will perform a failover. In this case, the secondary becomes the primary, serving all operations. Because the replication between the primary and secondary regions is asynchronous, in the event of a major disaster, data not yet replicated to the secondary region will be lost. You can also perform a manual failover of a geo-redundant storage account.

- **Geo-zone-redundant storage (GZRS)**: You can think of GZRS as ZRS, but with geo-redundancy. With GZRS, files are stored three times across three distinct storage clusters in the primary region. All writes are then asynchronously replicated to a Microsoft-defined secondary region. The failover process for GZRS works the same as GRS.

Standard Azure file shares up to 5 TiB support all four redundancy types. Standard file shares larger than 5 TiB only support LRS and ZRS. Premium Azure file shares only support LRS and ZRS.

General purpose version 2 (GPv2) storage accounts provide two other redundancy options that Azure Files doesn't support: read accessible geo-redundant storage (RA-GRS) and read accessible geo-zone-redundant storage (RA-GZRS). You can provision Azure file shares in storage accounts with these options set, however Azure Files doesn't support reading from the secondary region. Azure file shares deployed into RA-GRS or RA-GZRS storage accounts are billed as GRS or GZRS, respectively.
