Question

5. Your friend the veterinarian is very worried about losing all her patient data because of a hardware failure. As mentioned in an earlier question, she has client and medical records

for some 2500 pets stored on her server. She has heard that there are ways to configure a computer to ensure that there is an automatic backup being made of all data. Of course, this will not save her if someone breaks in a steals the actual server/storage devices, but she would like to invest in adding redundancy to her existing system. At least that way if a drive fails, she hopefully will still have access to her patient records and accounting records. Her systems vendor has told her that she should consider configuring RAID storage devices as these provide fail-over redundancy. Sadly, she knows nothing about "RAID" – it sounds like an insect repellant. She has also been told there are several types of RAID configurations. Her systems vendor is recommending either a RAID1 or RAID5 configuration. a) Your veterinarian friend has asked that you explain IN PLAIN LANGUAGE what is the difference between RAID1 and RAID5. No more than three relevant points are needed for each option. [6 marks] b) After learning about backup on RAID configuration options, which of RAID1 or RAID5 would you recommend to your friend, and why? [4 marks] You will need to do some independent research for this question. While we talked about the importance of storage backup in class, we did not explicitly review all the RAID configurations.
