GZRS (Geo-Zone-Redundant Storage) replicates your data synchronously across availability zones within the primary region and asynchronously to a secondary region, providing protection against both zonal and regional failures. This ensures that your data remains highly available and durable even if an entire region becomes unavailable.

ZRS (Zone-Redundant Storage) replicates data synchronously across availability zones but does not replicate to a secondary region, so it does not protect against regional outages. GRS (Geo-Redundant Storage) replicates data to a secondary region but only stores data in a single zone in the primary region, lacking protection against zonal failures. LRS (Locally Redundant Storage) stores multiple copies of data within a single data center, offering the least redundancy.
