Blu-ray back up of DVD that will never be commercially made?

Hello, I have a legitimate copy of one of my favorite movies in DVD but I'm worried about losing it to time. The movie is called Evolver, it's a killer robot movie from 1995 and it's super nostalgic for me. Is there a way to preserve it on Blu Ray, since the DVD is legit I would assume it has some sort of copy protection.
