+# Active-Active Data Replication between Primary and DR Sites
+
+KubeStash supports real-time and secure data replication between the primary data center (DC) and the disaster recovery (DR) site operating in active-active mode. Backup snapshots are replicated across multiple `BackupStorage` targets simultaneously, so the same logical snapshot is materialized in DC, DR, and any Near-DR site. For the live data path, KubeStash works together with KubeDB, which provides engine-native synchronous multi-master replication (MySQL Group Replication, Galera, MongoDB cross-region replica sets, PostgreSQL Patroni stretched clusters). Both sites remain authoritative and writable, with RPO near zero. Data in transit is encrypted end to end.
