  title: Amazon Neptune Analytics Snapshot and Restore
  summary: Snapshot a Neptune Analytics graph, wait for the snapshot, then restore it into a new graph.
  description: >-
    A backup-and-clone workflow for Neptune Analytics. It creates a snapshot of a
    source graph, polls the snapshot until its status is AVAILABLE, and then
    restores a brand-new graph from that snapshot. The snapshot poll loop uses a
    retry delay to handle the CREATING state. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
