public void setPreSignedUrl(String preSignedUrl) {
        this.preSignedUrl = preSignedUrl;
    }
<p>
The URL that contains a Signature Version 4 signed request for the<code>CopyDBClusterSnapshot</code> API action
in the Amazon Web Services Region that contains the source cluster snapshot to copy. You must use the
<code>PreSignedUrl</code> parameter when copying a cluster snapshot from another Amazon Web Services Region.
</p>
<p>
If you are using an Amazon Web Services SDK tool or the CLI, you can specify <code>SourceRegion</code> (or
<code>--source-region</code> for the CLI) instead of specifying <code>PreSignedUrl</code> manually. Specifying
<code>SourceRegion</code> autogenerates a pre-signed URL that is a valid request for the operation that can be
executed in the source Amazon Web Services Region.
</p>
<p>
The presigned URL must be a valid request for the <code>CopyDBClusterSnapshot</code> API action that can be
executed in the source Amazon Web Services Region that contains the cluster snapshot to be copied. The presigned
URL request must contain the following parameter values:
</p>
<ul>
<li>
<p>
<code>SourceRegion</code> - The ID of the region that contains the snapshot to be copied.
</p>
</li>
<li>
<p>
<code>SourceDBClusterSnapshotIdentifier</code> - The identifier for the the encrypted cluster snapshot to be
copied. This identifier must be in the Amazon Resource Name (ARN) format for the source Amazon Web Services
Region. For example, if you are copying an encrypted cluster snapshot from the us-east-1 Amazon Web Services
Region, then your <code>SourceDBClusterSnapshotIdentifier</code> looks something like the following:
<code>arn:aws:rds:us-east-1:12345678012:sample-cluster:sample-cluster-snapshot</code>.
</p>
</li>
<li>
<p>
<code>TargetDBClusterSnapshotIdentifier</code> - The identifier for the new cluster snapshot to be created. This
parameter isn't case sensitive.
</p>
</li>
</ul>
