Yes, there is a small chance your back-up hard-drive may go. But he was asking about backing up a a desktop and not a server. There is a big difference on the life of a drive depending on it's use. I highly doubt that both drives will go at the same time. We've been mirroring all our home drives for years, and have never had a problem.
I was providing an inexpensive and simple solution, nothing more. Like any advice or comments, he is free to accept or disregard it.
