That reminds me of my first job (late 70's)where one of the project leads was paranoid about losing data from experiments (eficiny of mixing in tanks)

He had 2 copies on floppy two on disk (in a separate building) and another set at home on floppy's

That's why in 1979 I used to by 8 inch floppy's in multiples of thousands
