-Azure Storage redundancy options can have implications on data residency as Azure relies on [paired regions](../availability-zones/cross-region-replication-azure.md) to deliver [geo-redundant storage](../storage/common/storage-redundancy.md#geo-redundant-storage) (GRS). For example, if you're concerned about geo-replication across regions that span country boundaries, you may want to choose LRS or ZRS to keep Azure Storage data at rest within the geographic boundaries of the country in which the primary region is located. Similarly, [geo replication for Azure SQL Database](/azure/azure-sql/database/active-geo-replication-overview) can be obtained by configuring asynchronous replication of transactions to any region in the world, although it's recommended that paired regions be used for this purpose as well. If you need to keep relational data inside the geographic boundaries of your country/region, you shouldn't configure Azure SQL Database asynchronous replication to a region outside that country/region.
