Patent ID: 7908246

Claim:
A method of transmitting a data file from a first system to a second system, the method comprising: identifying data included in the data file, prior to transmission of the data file in a data stream to the second system, such that the second system can distinguish first data from second data in the data file, wherein the first data comprises information stored in the data file as content and the second data comprises information associated with said content; processing the first data and the second data to determine whether the first data or the second data has changed; transmitting the first data to the second system in response to determining that the first data has changed, so that the first data is stored in a data storage medium coupled to the second system in association with third data and fourth data previously stored in the data storage medium, wherein the third data and the fourth data comprise older versions of the first data and the second data, respectively, and wherein storing the first data in the data storage medium does not replace the third data and fourth data; transmitting the second data to the second system excluding unchanged portions of the second data, in response to determining that the second data has changed; and indicating a restore point for restoring the first data to a prior version, wherein the second system processes the second data and fourth data stored in a data storage medium to determine whether security controls will be backdated.
