Replicating data across different geographic regions to protect against regional disasters. Like keeping backup files in different cities or countries.
Critical business data is replicated from US East to US West regions to survive regional disasters like hurricanes or earthquakes.
All provide ways to keep copies of data in separate geographic locations. AWS S3 CRR and OCI Replication copy objects between regions. Azure GRS/RA-GRS replicates storage to a paired region (optionally readable). GCP dual-region stores data redundantly across two regions within a chosen geography.
