Backing up and restoring volumes
Since we're dealing with servers, the data that's being stored on our storage devices 
is no doubt going to be extremely important. While it's normal to have a few test 
servers for use as test subjects in a typical environment, our servers usually exist 
to carry out a very important task. I can tell you from first-hand experience, never 
put too much trust in storage devices. In fact, I recommend not trusting them at 
all. I consider all storage to be temporary, as hard drives can and do break. If your 
important data is only stored on one device, it's not safe. In this section, I'm going to 
discuss some very important topics around backups.
