Backup the sims

[trempas]

I can't make a backup of The sims : Living large (Ça vous change la vie in french version) for few days.I have tried with clone CD.
I believe that the protection is safedisc ( I don't know exactly wich one).
Can't you help me ?
Does Clone CD works with this game?
I have download Unsafedisc but I don't know how to use it.
Thank's a lot.
