*background independence in string theory*?

I understand this concept in the context of general relativity and loop quantum gravity; there it means

*invariance with respect to active, local diffeomosphisms*. In string theory the AdS/CFT conjecture is mentioned, but I do not understand, how this guarantuees background independence. Both the string and the conformal field theory are put on top of a certain background.

Thanks
