Backupme - Connection Manager missing - cakephp

Question

I'm using this shell script below. I have it in app/console/command/BackupShell.php
When I run the script I get this error:
Fatal error: Class 'ConnectionManager' not found in app/Console/Command/BackupShell.php
What am I doing wrong?
class BackupShell extends Shell {

//database configuration, default is "default"
if(!isset($this->args[0])){

Answer 1

Is this 2.x code?
App::import('Core', 'ConnectionManager');
is deprecated/wrong in 2.x and should be
App::uses('ConnectionManager', 'Model');
and also be placed at the top of the file, right after the <?php tag
