A copy, by itself, may or may not be a backup

If that "point in time copy" is on an external HD disconnected from the computer with your data on it, sitting next to it on your desk, and if an operating system bug or malware wipes stuff from your computer, that copy is a backup. If both items are in your basement office which is flooded, that copy is not a backup.

What can be called a backup depends on the adverse conditions one is attempting to protect himself from. The more the better, before a point of diminishing return.
