Which Azure feature provides continuous data availability across multiple geographic locations?

Read-Access Geo-Redundant Storage (RA-GRS) provides continuous data availability by asynchronously replicating your data to a secondary region hundreds of miles away from the primary region. This ensures data durability even in the event of a regional outage, and allows read access to the secondary copy. Azure Site Recovery is a disaster recovery service for virtual machines, not a storage redundancy option. Availability Sets protect against planned and unplanned maintenance events within a single data center, not across geographic locations. Local Redundant Storage (LRS) provides durability within a single data center and does not offer geographic redundancy.
