Then provide a <code>FileSystemId</code> value to the <code>DeleFileSystem</code> operation.</p> <p>By default, when you delete an Amazon FSx for Windows File Server file system, a final backup is created upon deletion. This final backup isn't subject to the file system's retention policy, and must be manually deleted.</p> <p>The <code>DeleteFileSystem</code> operation returns while the file system has the <code>DELETING</code> status. You can check the file system deletion status by calling the <a href="https://docs.aws.amazon.com/fsx/latest/APIReference/API_DescribeFileSystems.html">DescribeFileSystems</a> operation, which returns a list of file systems in your account.
