Good point about keeping a hard copy. As for hard drive backups, we always keep three generations (called grandfather, father, son) of backups on three different portable hard drives. The idea is to use a different drive each time you do a backup. We do monthly backups of everything, so we three months worth of backups. One backup is never sufficient.

I had one class in high school in the 1960s where we did an exercise with IBM punch cards. I didn't quite grasp that one at the time, but I understood that it could take a couple of hundred individually punched cards and a computer the size of a locomotive to balance your check book. That was state-of-the-art in the 1960s.
