A recording system stores files on a removable, optical record carrier (11). The record carrier has an annular recording area corresponding to a logical data space accessible according to a predefined recording format. The recording system has a control unit (20) for controlling the recording means for storing the files in respective data blocks. A backup unit (32) stores at least one backup file of an original file, and assigns, to the backup file, backup blocks in the logical data space. The backup blocks (305,306,307) are physically positioned remote from corresponding original blocks (302,303,304) of the original file in the logical data space, e.g. by applying a predetermined radial shift. Hence the record carrier is provided with reliable data, wherein the backup blocks and the original blocks form a spatially distributed pattern for avoiding that local disturbances of the recording area affect corresponding blocks of the original blocks and backup blocks.
