Abstract:

This report presents testing and improvements to a protocol, raync, for the synchronisation of similar data files in different locations. When copying a file A at location a to a remote locations. it is often the case that A has much in common with some data file B already stored at Beta. In this situation raync may be used to effectively send File A from a to Beta in such a way that much less data than that contained in A is transmitted. Moreover this is achieved without requiring both files to be located at either alpha or beta. This paper provides new checksum functions that offer significant improvements over the existing functions, and proposes that checksum sizes be adaptive based on a verified model of the required checksum size.
