Copying a Snapshot

This section describes how to copy snapshots that are automatically created to generate manual snapshots for long-term retention.

Copying an Automated Snapshot

  1. Log in to the DWS management console.
  2. In the navigation tree on the left, click Snapshot Management.

    All snapshots are displayed by default. You can copy the snapshots that are automatically created.

  3. In the Operation column of the snapshot that you want to copy, click Copy.

    • New Snapshot Name: Enter a new snapshot name.

      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 (_).

    • Snapshot Description: Enter the snapshot information.

      This parameter is optional. The snapshot description contains 0 to 256 characters and does not support special characters !<>'=&".

  4. Click OK. The system starts to copy the snapshot for the cluster.

    The system displays a message indicating that the snapshot is successfully copied and delivered. After the snapshot is copied, the status of the copied snapshot is Available.

    NOTE:

    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?.
