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!

Thanks & Regards
Siddhartha Sharma
