Abstract
The rsync algorithm is tuned so to obtain optimum cloud storage performace. More than50000 emulations with the “real rsync” and real files have been carried out so to obtain informationon the algorithm’s performance. The performance of cloud storage is said to be optimumwhen the number of bytes trasmitted with every synchronisation is minimum. Hence I alsopresent a model that captures the number of bytes that are transmitted through the rsync link.This model was validated by simulating it and comparing the results to the outcomes of theexperiments that were performed. Finally by analysing the model mathematically I extractedan expression that gives the optimal block-size which depends on the size of the file and thechanges made to it
