Hi Sandeep,
To schedule any task, not only a clone task, create the task and save it, then right click on the task and select 'Schedule'. Once the 'Ghost Console scheduled Tasks' window is opened, go to 'Schedule' tab and select the frequency (daily, weekly, monthly etc) and time you want your task to run.
Very important, in order for the task to run, you must set a password. For this, select the 'Task' tab and press 'Set password' button, then enter your password and confirm it.
Hope this helps,
Adina
