3D backup

[Sbpbp]

I was just wondering if I need something special to make a 1:1 backup of a 3D movie or do I need to purchase the 3D ripper software and if so what would be the steps to create the backup....

All you need is DVDFab Blu-ray Copy and use Clone Mode and the BD50 size as not able to compress at the moment.
