A process for the management of data of an analysis device, which data serve for the operation of a further analysis device which is designed so as to be equivalent to the first analysis device, is disclosed. The analysis device newly creates or modifies data on an internal memory medium of the analysis device and the first analysis device, during its operation, continuously stores the newly created or modified data in a redundant manner in a non-volatile removable storage medium, with the removable storage medium being independent of the internal memory medium.
