Hello. I am suggesting the R-TT Team to see and may be implement the same functionality as Shadow Explorer in http://www.shadowexplorer.com
As you can see, shadow explorer searches, shows and allows to recover previous copies of the files as long as there will be Windows Restoration Points. Obviously it is a Windows Only functionality but remember that all the current ransomware are Windows related.
And by the way, don't forget to try shadow explorer, may be the original lost files were saved in previous restoration points. The current ransomware destroys restoration points but R-Studio can recover. The problem is where to go once restoratioin points were recovered by R-Studio. That is the question now. The only programs I found that understands the structure of restoration points are Windows and shadow explorer & shadow copy view each with pros and cons
