[Users] Copy VM using the commandline

Is it possible to copy a VM from storage node to storage node by using the commandline ? ISO images are indexed automaticly but I don't know how this works for storage. I have a storage device that was "down" following the system, but my images are still on there. To avoid reinstalling the systems and placing backups back I would like to know if I can copy the images from this folder to a storage device that can be seen normal. I hope this is possible. Cheers, Matt
