This is more of a joke from a conversation amongst the Veeam slack channels. How do you explain what Veeam is to some one who is not tech savvy? I came up with the following analogy:
You have a pie that you really like. If you ate the pie then you would no longer have the pie. Veeam can either make a backup of that pie in the freezer for you to recover later or store a replica copy of the pie in the fridge for you to eat now.
So the above has the basic constructs for backup and replication. Replace pie with whatever is relevant to the person you are talking to.
