Methods of reproducing and recreating original data are provided. A method of reproducing original data is provided wherein original data are received in a first format and native data are extracted from the original data in a second format. Moreover, derivative data are generated from the native data in a first format with the derivative data compared to the original data producing a difference data. The difference data are used with the native data to create a replica of the original data. Further, a method of recreating a replica of original data is provided comprising receiving native data in a native format which are extracted from an original data in an original format. Also, derivative data are generated from the native data in an original format. A replica of the original data is reproduced by using the derivative data and difference data, wherein the difference data identify differences between the derivative data and the original data. Moreover, a method of creating a replica of original data is provided comprising generating derivative data from native data wherein the derivative data are in the same format as original data. Difference data are produced to record the differences between the derivative data and the original data. A replica of the original data are created using the derivative data and the difference data.
