What is the proper procedure to back-up ones hard drive?

There is no need to back up your hard drive - 99% of the information of the drive is programs and operating system data which is easily duplicated.
If you want to protect your own data, you can copy the files to your Z:\ drive which will keep them on the server. This location is backed up nightly.

Another option is to store all your files on Google Drive (using your Brenau account) which is also supported.
