A cloud storage appliance receives one or more read requests for data stored in a storage cloud. The cloud storage appliance determines, for a time period, a total amount of bandwidth that will be used to retrieve the requested data from the storage cloud. The cloud storage appliance then determines an amount of remaining bandwidth for the time period. The cloud storage appliance retrieves the requested data from the storage cloud in the time period to satisfy the one or more read requests. The cloud storage appliance additionally retrieves a quantity of unrequested data from the storage cloud in the time period, wherein the quantity of retrieved unrequested data is based on the amount of remaining bandwidth for the time period.
