Backup

Question 1 - Backup mix:

  1. Which three points would you deem the most important when constructing a catastrophe plan.
  2. For those of you that has the responsibility for a network or access to one: investigate what backup medium is being used (tape, disks…) and set up the backup plan for your network. Include the retention policy and evaluate the plan considering the contents of this lesson

From an exam 18.05.95:

Question 2 (weight 15% of a 5-hour exam)

  1. A short description of to different firms/institutions. As the EDB-consultant you have been given the task of sketching out a backup strategy for these. The task is to formulate three different backup strategies for each one, with differing thoroughness. You will have to consider the description of each one below and your own assumptions to find each institution's need for security, and range the three different alternatives for their thoroughness. There will totally be six different strategies. Assume that all the networks are Novell 3.11.
    1. Trondheim Torg is a shopping centre that uses network stations in every store. The network is primarily used to communicate between the shops and the board of leaders. Information about sales and the employees is stored on a central server. There are a total of 25 different workstations and one file server in the network. One of the employees has been assigned the title of network administrator in 50 % of his working time. Assume that every employee themselves has the responsibility for backing up their own workstation.
    2. Trondheim Psychiatric Hospital has a network with disk less workstations. The network is use to store information about patients, and for communication between the doctors and other employees to evaluate the patients situations. There are a total of 89 workstations, two fileservers and two network administrators in the network.

b) Imagine you being the system administrator for a network with 25 nodes. You get a note from the board that they will employ ten more people, and therefore the network will be expanded to support 35 nodes. What upgrades might you end up having to do?
