Azure storage option that asynchronously replicates data to a secondary region hundreds of miles away, maintaining 6 total copies across two regions. Protects against regional disasters.
Azure GRS replicates critical business data from East US to West US, ensuring data survives even catastrophic regional events.
All options increase durability by keeping copies in more than one geographic location. Azure GRS asynchronously replicates to a paired secondary region and is designed for regional disaster recovery; AWS S3 CRR replicates objects to a bucket in another region (typically configured per-bucket/prefix with replication rules); GCP dual-region/multi-region stores data redundantly across two or more regions with managed placement; OCI replication copies objects between buckets in different regions.
