How to use Delta Sharing to share data between Production and QA environment

[moattarwork]

I was wondering if the Delta Sharing can be used for sharing data between production and QA. Also I don't know if it is working as another copy of the data or it can act as virtualized (VHD) disk so the any changes in QA does not reflect in production data but QA only maintain the differences rather than the whole data set.
