Abstract:
1. A method for storing an incoming data stream, the data stream being composed of identifiable data units, comprising the steps of in a first storage device storing a first portion of the data stream on a first storage medium, and creating and storing a first data set associated to the first portion of the data stream, the data set containing an identifier for the first portion of the data stream; sending a request from the first storage device to one or more other storage devices; receiving in the first storage device one or more answers from the one or more other storage devices; selecting a second storage device from the one or more other storage devices from which an answer was received; storing in the selected second storage device the incoming data stream on the second storage medium; sending from the first storage device to the second storage device an identifier for the last data unit stored on the first storage medium, and storing the identifier together with the first data set in the first storage device; detecting in the second storage medium in the second storage device the identified data unit within said stored data stream; storing on a third storage medium in the second storage device a second portion of the data stream containing subsequent data units, and creating and storing a second data set associated to the second portion of the data stream, the data set containing an identifier for the second portion of the data stream; and storing at least one of the identifiers together with the other data set in the other storage device.
