Grubby Little Hands
I learned, long, long ago, that if I don't have the data in my grubby little hands, usually now in the form of a USB flash drive, or DVD, (or, decades ago, on a tape that I physically had possession of, or on floppy disks), then the data didn't really exist. I've heard, way too many times in my career, "Oh, that tape doesn't exist.", or "We erased/scratched that tape.", or, "We lost/broke that DVD.", or "We don't back-up those file types.".
