copy_cluster_snapshot

Redshift.Client.copy_cluster_snapshot(**kwargs)

Copies the specified automated cluster snapshot to a new manual cluster snapshot. The source must be an automated snapshot and it must be in the available state.

When you delete a cluster, Amazon Redshift deletes any automated snapshots of the cluster. Also, when the retention period of the snapshot expires, Amazon Redshift automatically deletes it. If you want to keep an automated snapshot for a longer period, you can make a manual copy of the snapshot. Manual snapshots are retained until you delete them.

For more information about working with snapshots, go to Amazon Redshift Snapshots in the Amazon Redshift Cluster Management Guide.

      The time (in UTC format) when Amazon Redshift began the snapshot. A snapshot contains a copy of the cluster data as of this exact time.

    • Status (string) –

      The snapshot status. The value of the status depends on the API operation used:

      • CreateClusterSnapshot and CopyClusterSnapshot returns status as “creating”.

      • DescribeClusterSnapshots returns status as “creating”, “available”, “final snapshot”, or “failed”.

      • DeleteClusterSnapshot returns status as “deleted”.

    • Port (integer) –

      The port that the cluster is listening on.

    • AvailabilityZone (string) –
