That is indeed a huge problem. My sister uses windows, which is more susceptable to viruses than the computer that has the raided hard drives, which is running linux. Her hard drive has been wiped due to viruses, but they didn't affect the linux backup server. It's like having a eunuch protect your harem

Another thing which helps minimize the risk of internet-borne viruses (virii?) is that the backup server is not connected to the internet. It is only on an internal network. Any virus/attacker has to be that much more determined.
While this may be a lot of effort to set up a (hopefully) secure and redundant backup system, it's probably worth it in a lot of cases.
That being said, there are other simpler backup schemes that are just as effective.
