Suppose that you work at a small firm and your manager has asked you to investigate using Dropbox to replace a tape drive that backs up a single server system with 12 TB of data. Your manager says the company spent $8,000 six years ago for the tape drive and tapes it uses, and that it pays a vendor $1,200 a month to pick up and deliver backup tapes to a secure facility each week. Would Dropbox be an economical replacement for the current process? Justify your answer based on costs and then based on other benefits.
