A snapshot is a complete backup that records point-in-time configuration data and service data of a data warehouse cluster. This section describes how to create a snapshot on the Snapshot Management page to back up cluster data.
The cluster for which a snapshot is to be created must be in the Available, Read-only, or Low performance status.
The snapshot name must be 4 to 64 characters in length and start with a letter. It is case-insensitive and contains only letters, digits, hyphens (-), and underscores (_).
This parameter is optional. The snapshot description contains 0 to 256 characters and does not support special characters !<>'=&".
Task status of the cluster for which you are creating a snapshot is Creating snapshot. The status of the snapshot that is being created is Creating. After the snapshot is created, its status becomes Available.
If the snapshot size is much greater than that of the data stored in the cluster, it is possible that data is labeled with a deletion tag, but is not cleared and reclaimed. Clear the data and create a snapshot again. For details, see section How Can I Clear and Reclaim the Storage Space?.
