trying to backup Shogun total war, please help

[mrcow]

hello everyone, i hope this isn't a silly question, but i really would like your advise. i read a few post on backing up your software. I have clone cd, an older version, (i believe) i am trying to make a backup of shogun total war.(great game) I think i have a okay copy but the no cd crack isn't working. Well, i would like to know is clone cd the best software for backing up Shogun total war. What would be the best software to make a 1:1 copy. Are the patchs working? Well, i would welcome any advise you can give me at this point. Thanks everyone
