Data access and management system and data access and management method for a computer system

Data access and management system for a computer system, comprising: - At least two data storage means (C1, C2, ..., Cn), - At least one computer unit (CL) which accesses data of the data storage means (C), - Data transmission means (N) for data transmission between the data storage means (C) and the computer unit (CL), said data are stored redundantly in at least two of the at least two data storage means (C), and - Means for detecting predetermined parameters of the data transmission between the data storage means (C) and the computer unit (CL), said data as a function of the determined prespecified parameters in the data storage means (C) are redundantly stored, and wherein the computer unit (CL) as a function of the determined prespecified parameters of the data to a storage means (C) accessing, characterized in that - The data storage means (C) means for detecting predetermined parameters for data transmissions between the data storage means (C) comprise - The data storage means (C) move redundantly stored data based on the determined parameters of data transmissions between which data storage means (C) independent of an access to the computer unit (CL) in the system.
