"Only original data are stored in the vault; no copies are allowed anywhere" means no backups. As a user, I don't want that; I want my data to be available independently of the physical medium it is stored on.

Even more problematic is: What about data stored on disk, for example, and in memory? That's two copies. Is that allowed? If so, how does that meet the requirement of "no copies allowed"?

You can define the vault to include it’s backups, so that’s not really an issue, but you’re right that defining access in terms of copies is problematic. Copyright laws already address this by defining who has the right to make and distribute and consume copies rather than trying to define what exactly constitutes a copy in the digital age. Maybe what they need first is to establish a copyright over personal data that cannot be transferred, similar to Moral Rights?
