Create Custom Tasks

function hook_hosting_tasks() { $options = array();

$options['site']['clone'] = array( 'title' => t('Clone'), 'description' => t('Make a copy of a site.'), 'weight' => 5, 'dialog' => TRUE, ); return $options;}

Define task for context (server/platform/site)

Create Drush Commandfunction hook_drush_command() { $items['provision-clone'] = array( 'description' => 'Clone a site between platforms.', 'arguments' => array( '@new_site' => dt('The Drush alias of the new site... '@platform_name' => dt('The Drush alias of... 'examples' => array( 'drush @site provision-clone @new_site @pla... ), 'bootstrap' => DRUSH_BOOTSTRAP_DRUPAL_ROOT ); return $items;}
