Protecting storage of data e.g. for video monitoring of cash machines or self-service petrol pumps, by using dynamic storage expansion to protect excess data when storage capacity has been reached

摘要

The data are archived on a data store (1) for a predetermined time period. When the capacity limit of the data store has been reached, the excess data are protected by a dynamic storage expansion. In the event of a very small data amount, storage space is made available by the data memory for other uses or other data. An Independent claim is included for an apparatus for protecting the storage of data.
