Abstract

A method for transferring data blocks from a first device to a second device is described, in which the second device stores signatures relating to respective data blocks stored on the second device, each signature relating to contents of the associated data block. For each data block to be transferred from the first device to the second device a signature for the data block concerned is transferred from the first device to the second device, it is determined whether the received signature is stored on the second device, and if the received signature block is not stored on the second device, the data block is transferred to the second device, and the received signature block and the data block are stored on the second device.
