Question: Think about an organization, which has a rented communications channel in two buildings, building A and building B. They have a set of servers in building A, and want to back up critical data on an hourly basis to a set of storage drives in building B. They know that the channel has a bandwidth of 10KHz and a signal-to-noise ratio of 20dB.
(i) If their server system generates an average of 45 MB of data each hour, can they use this channel to implement the back up? Explain your answer.
(ii) The organization anticipates a doubling of generated backup requirement in the next year. What advice would you offer in respect of their back up options?
