Read-access Geo-Redundant Storage (RA-GRS) replicates your data to a secondary region and allows you to read from the secondary location if the primary region becomes unavailable. This ensures your data remains accessible during a regional outage.

Geo-Redundant Storage (GRS) also replicates data to a secondary region but does not provide read access to the secondary unless Microsoft initiates a failover, so your data would not be accessible during an outage.

Zone-Redundant Storage (ZRS) replicates data across availability zones within the same region and does not protect against regional outages.

Locally Redundant Storage (LRS) keeps multiple copies of your data within a single data center, offering no protection against data center or regional failures.
