The exact set could be from a single VM (with its associated resources:
images, volumes, etc) to a set of entities associated with a user.
The data-center itself (including its metadata and configuration) is
consider the equivalent of the "hardware" - in case of disaster, you
recover "what is running", not the infrastructure.

Thanks for pointing out the scope should be emphasized at the top...
