removed "#Backup" comment (because why not)
added the host in the scp new() method and removed from the scp method
removed scp->login() method and added user and password options directly in constructor)
added recursive option into scp constructor as suggested by Marc (thanks to him)
CONF_Riverbed_CMC : typo with a $ ; removed recursive because it makes the scp to be multiplexed ; added a ":" into the scp commande to specify the remote
CONF_Riverbed_CMC : used error_handler() method to... handle errors, even though error messages ar far less explicit... But hey, this method is here so we should use it
