After you create a snapshot, you can copy the snapshot within the same region or across different regions. The new snapshot will be assigned a different ID from that of the source snapshot.

Prerequisites

At least one normal snapshot is created for a disk. For more information, see Create a normal snapshot.

Background information

The snapshot copying feature is available in the following regions:
  • China (Hangzhou), China (Shanghai), China (Qingdao), China (Beijing), China (Zhangjiakou), China (Hohhot), China (Ulanqab), China (Shenzhen), China (Heyuan), and China (Chengdu)
  • China (Hong Kong), Singapore, Australia (Sydney), Malaysia (Kuala Lumpur), Indonesia (Jakarta), Japan (Tokyo), Germany (Frankfurt), UK (London), US (Silicon Valley), US (Virginia), and India (Mumbai)

When you copy a snapshot, take note of the following items:

  • Billing:
    When you copy a snapshot across different regions, a snapshot copy is created. It will incur storage fees and snapshot replication service fees. For more information, see the Pricing tab on the Elastic Compute Service page.
    Note When a disk snapshot is copied for the first time, all content stored on the disk is copied. All subsequent copies of the snapshot in the same region are incremental copies. Snapshot are billed based on the snapshot size. Incremental copies can significantly reduce snapshot sizes.
  • Scenarios:
    • DevOps: You can copy snapshots to quickly start business in new regions or migrate business systems to new regions. This helps you reduce O&M costs and achieve higher data availability.
    • Cross-region backup: Snapshot copying meets the requirements of compliance audits and improvement of business reliability. You can restore your business system in another region by using new snapshots in the event of a disaster. This reduces recovery time objective (RTO) and recovery point objective (RPO).
  • Limits:
    • A new snapshot that you copied from its source snapshot cannot be used to roll back the disk from which the source snapshot is created.
    • Tags bound to source snapshots cannot be copied together with source snapshots.
    • Encrypted snapshots cannot be copied.
    • Local snapshots cannot be copied.
