Yesterday, a disk drive containing your engineering departments project documents crashed. fortunately, there was a backup, but all files that had been added or changed that day were lost. a new disk drive has to be purchased, and the data has to be restored. several days of work time will be lost. mr. phoenix, the ceo of the company wants to know what can be done to prevent the loss of data and time if a disk crashes in the future. the server currently has two disks installed: one for the windows boot and system volumes and one for project document files. the disk used for project document files is about one-third full. there is enough money in the budget to purchase up to two new drives if needed. what solution do you recommend, and why?
