If you select a smaller number of days to retain snapshots in the destination region, any automated

snapshots that were taken before the new retention period will be deleted. If you select a larger

number of days to retain snapshots in the destination region, the retention period for existing automated

snapshots will be extended by the difference between the old value and the new value.

5. Click Save Configuration.

Disabling Cross-Region Snapshot Copy

You can disable cross-region snapshot copy for a cluster when you no longer want Amazon Redshift to

copy snapshots to a destination region.

To disable cross-region snapshot copy for a cluster

1. Sign into the AWS Management Console and open the Amazon Redshift console at https://

console.aws.amazon.com/redshift.

2. In the navigation pane, click Clusters.

3. Click Backup, and then click Configure Cross Region Snapshots to open the Configure Cross

Region Snapshots dialog box.

Managing Snapshots Using the AWS SDK for

Java

The following example demonstrates these common operations involving a snapshot:

• Creating a manual cluster snapshot of a cluster.

• Displaying information about all the snapshots of a cluster.

• Deleting manual snapshots of a cluster.

In this example, a snapshot of the cluster is initiated. When the snapshot is successfully created, all

manual snapshots for the cluster that were created before the new snapshot are deleted.When creation

of the manual snapshot is initiated, the snapshot is not immediately available. Therefore, this example

uses a loop to poll for the status of the snapshot by calling the describeClusterSnapshot method. It

normally takes a few moments for a snapshot to become available after initiation. For more information

about snapshots, see Amazon Redshift Snapshots (p. 82).

For step-by-step instructions to run the following example, see Running Java Examples for Amazon

Redshift Using Eclipse (p. 130).You need to update the code and provide a cluster identifier.
