Abstract

The invention relates to a system and method of protecting data stored on an optical disc, said method comprising the steps of: - replicating (101) the data of said optical disc to a first storage device, - reading out (102) the data from said optical disc, - generating (103), from a quality parameter of the read out data, an output signal indicating a good or low quality of said optical disc, and - writing (104) the data of said first storage device to a second storage device if said output signal indicates a low quality.
