Brian was running backup with Carbonite and his hard drive crashed during the backup. Leo says that's bad luck and is likely a coincidence. Fortunately, Brian had a local backup. Leo says that a good backup strategy is what is known as a 3-2-1 backup. Three copies on two different formats, with one being off-site. Backing up and then deleting the original is not a backup. Redundancy is the key.
Leo says that there's a great utility called Second Copy which will update any changes to the main hard drive to the backup hard drive. It makes the second drive automated with every copy he has. SyncToy is from Microsoft, and it's free. He could also try SyncBack.
