Target customers: all users. Features released: The cross-region snapshot replication feature is released to allow users to copy a normal snapshot from one region to another. The snapshot copy is assigned an ID different from that of the copied snapshot. This feature is applicable to the following scenarios: DevOps: You can copy snapshots to start business in new regions or migrate business systems to new regions. This helps you reduce O&M costs and improve data availability. Cross-region backup: Snapshot replication helps meet the requirements for compliance audit and improvement of business reliability. You can restore your business systems by using new snapshots in another region in the event of a disaster. This reduces recovery time objectives (RTOs) and recovery point objectives (RPOs).
