Claim:
A method implemented to run on one or more processors for transmitting a data file from a first system to a second system, the method comprising: distinguishing first data included in the data file from second data included in the data file, prior to transmission of the data file to the second system; determining 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, wherein the first data is stored in a data storage medium coupled to the second system in association with third data previously stored in the data storage medium; 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, wherein the second data is stored in the data storage medium in association with 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 the fourth data; and indicating a restore point for restoring the first data to a prior version, wherein the second system utilizes the second data and the fourth data to determine whether security controls will be backdated.
