   > When it went to flip into the backup, we discovered that the backup fiber had a break

   Pretty grim that a life critical system wasn't designed to report that the backup fibre was unserviceable until they attempted to switch over to it.

   I wonder how long it was down? Days, weeks, months?

      A lot of people don't check their backups until they need to restore.

      A lot of people are incompetent.

         A backup without a restore test isn't a backup at all

            You don't always have a copy of your hardware to restore onto. And the test's entire purpose is that you're not yet sure whether your restore will truly work. So you can't just run a backup and restore on your true prod system, because you're not sure it won't wreck it. So you need extra money to have a second system onto which you try to restore. If you don't have a lot of money, you will want to actually use your disks for storage, not to put them into a second testing server. Of course I'm not talking about very professional companies with super critical data. Just simpler smaller scale places or consumers.
