This year, I bought my first backup drive ever (8TB). I've wanted one for years but couldn't afford one. I learned a hard lesson when I lost my whole hard drive (and every pet photo on it) circa 2009.
Doing a modified files backup every week is far easier than redownloading/recropping/unstretching/remuxing 3000 TV episodes and 1000 movies in the event my movies drive crashes or the wife ever does an "oopsie".
Sorry for your loss.

I have officially retired from sucking at everything I do. Life is much easier now.
