NetApp SnapMirror cascade replication topology spans three clusters across two data centers, protecting critical data through sequential volume replication. Volume 1 in Cluster 1 (DC1) replicates to Volume 2 in Cluster 2 (DC1), which then cascades to Volume 3 in Cluster 3 (DC2), creating a multi-tier disaster recovery chain. This architecture enables storage administrators to maintain local and remote copies while minimizing WAN bandwidth consumption and meeting compliance requirements for geographically distributed backups. Fork this diagram on Diagrams.so to customize SVM configurations, add SnapMirror policies, or model your own cascade topology with additional tiers. Cascade replication is ideal for organizations requiring multiple recovery points across metro and remote sites without direct source-to-destination replication overhead.
