My mind directly went to Laserdisc before I realized you were talking about the generic category 😅.
cd/dvd/blueray doesn’t become bad that fast, properly stored they can easely live to 50+ years (except the writeable variant). they are physically etched which helps with longevity.
VHS or other types of magnetic storage is more of a chore, they often don’t survive the passing of time.
Systemd timer to poll upower when running on battery power, when battery is at 20%, use either system beep or set system volume and play a sound?
