== RAID IS NOT A BACKUP! == <blockquote>'''IMPORTANT NOTICE: RAID 1 IS NOT A BACKUP!''' Many people incorrectly believe that RAID 1 is a “backup.” It is not! RAID 1 sets up your machine so that the operating system is installed on TWO drives rather than one, with each drive being an exact mirror of the other. This way, if one drive fails while you’re using your server, it will still run. Think of RAID 1 like the green goo you can put in your tire to plug up a hole, or a spare wheel, allowing you to limp to a service center for repairs. </blockquote> Here are a few reasons why RAID 1 is not a backup: # Backups allow you to restore your system if you accidentally mess something up. RAID 1 is a perfect mirror, so it applies to everything you break. # RAID 1 means you’re attaching two hard drives to your computer to install the operating system on instead of one. These drives are both connected to the same computer. If your computer’s power supply fails and sends incorrect voltages to the drives, both get fried. # When one drive in a RAID 1 array fails, the other often fails soon after, especially if they’re the same brand and were purchased at the same time. # RAID 1 works so well that you might not notice when one drive fails until the second one also fails, leaving you with no data. <blockquote>'''NOTE:''' MDADM does work well enough that you won’t tell when a drive fails. Later in this guide we’re going to set it up so that your machine is constantly checking & emails you the moment there is any issue with your drive using mdadm’s monitor command. </blockquote> <span id="step-by-step-installation-guide"></span>
