How to load a dataset with load_from disk and save it again after doing transformations without changing the original? 
Hi ! That looks like a bug, can you provide some code so that we can reproduce ?
It's not supposed to update the original dataset
I am using the latest datasets library.  In my work, I first use **load_from_disk** to load a data set that contains 3.8Gb information. Then during my training process, I update that dataset object and add new elements and save it in a different place.  

When I save the dataset with **save_to_disk**, the original dataset which is already in the disk also gets updated. I do not want to update it.  How to prevent from this?
