[Clonezilla-live] Create an image of the disk without rebooting the server

[G. M. <gma...@is...>]

Hello everybody,
first of all,
Thank you for Clonezilla... it's a fantastic system for cloning machines :-)

I need to create images of a server hard-disk... but I cannot restart 
and boot the clonezilla-live for create the image.
So, It would be fantastic if there is a way to run a command (script) 
that create the image without rebooting the server machine.

There is a way to extract the command from clonezilla-live CD and 
install into my Linux Server and run it with a crontab ???


Thank you,
Gianluca
