Just go play disc golf! Lots of fun, just as much exercise, and free (in most locations) to play. Also, *WAY* cheaper to get into than buying or renting clubs!
My storage array is only 8TB, but I doubled down and built another 8TB array in a small Lian Li case. I do a mirror backup to it once a week or so, and carry it to work with me. That way, it's offsite in case something physically happens to my home.
