DataRedux DataRedux examines the "digital DNA" of incoming data within and across multiple data streams, eliminating duplicate data at a sub-file level. DataRedux is performed in-line, that is before data is stored on disk for maximum storage efficiency. By not storing redundant data multiple times, HYDRAstor's DataRedux can reduce overall storage needs by more than 75% depending on your data. The economic impact, however, goes beyond your storage acquisition costs to also reduce power, cooling and other environmental costs.cf.
