Look for the options that include 'Geo' in the name, indicating geographical separation.
Full Answer
Geo-redundant storage (GRS), Geo-zone-redundant storage (GZRS)
To protect against a complete regional outage, data must be replicated to a secondary region. Geo-redundant storage (GRS) and Geo-zone-redundant storage (GZRS) both replicate your data to a secondary region that is hundreds of miles away from the primary region.
Common mistakes
Selecting ZRS. Zone-redundant storage protects against datacenter failure, but not a full regional failure.
