What you are looking for is called RAID (Redundant Array of Inexpensive Disks). You can get a pretty good overview at http://linas.org/linux/Software-RAID/Software-RAID-1.html. Even though this is written for Linux, the basics of RAID are the same. From there, things get complicated and/or expensive. I still recommend doing a backup and then sending it via email to a sibling, cousin or your work.
