A system includes a first data server storing a first data file for a user and a second data server storing a second data file for the user, wherein a pre-authorized secure connection can be established between the first data server and the second data server. The second data file receives a request for a first amount of data from the second data file and detects that the first amount of data is larger than a second amount of data in the second data file. The second user determines that the first data file at the first data server includes a third amount of data that equals or exceeds a difference between the first amount and the second amount, and receives a fourth amount of data that equals the difference from the first data server over the pre-authorized connection. In response, the second data server processes the request.
