Hi Tomek, Thanks for your reply and information provided.
Well, I would say I didn't take the backup as I wasn't even expecting my company would never return my files in the first place. After my project, I was already planning to transfer all locally commited files to a git repository but just didn't get the chance to do so. After that my SSD got corrupted as well and I tried to get the data recovery but I think I need yo find a better data recovery solutions company to do this. Apart from that, no other way to get it back so I am contacting you as my last resort. I understand that it may seem like a felony but certain situations may demand for such incidents so if possible to take the backup and snapshots, please let me know. Awaiting your response!
