Russ,
   
  RAID = Redundant Array of Independent Disks
   
  A group of disk drives with a special type of disk controller that is configured in a manner so that data is written across multiple drives instead of just one, usually with one drive that is dedicated to an error correction algorithm so that if one drive goes bad, life goes on.  Replace the bad drive, and the good one (in conjunction with the error correction drive) will populate the new drive with the data that is supposed to be there.  Complexity?  Connect it to a network jack, plug it in, give it a name and address and start using it.  Two-five minutes and its available.  700 protected gigabytes for $450-500.  It could save your butt many times over without taking a chunk out of it to pay for it.

Most of my files aren't large - usually 1.5 meg or less, whether
they're audio or data. Not a lot of photos, virtually no music. Once
upon a time, I had the luxury of offsite backup, but no longer, except
for maybe some back-up CD's. 

Obviously somewhere along the line, I missed out on what exactly this
"RAID" solution you and others are talking about really is, and what
level of expertise one should have to attempt it. But I'd do an awful
lot of manual back-up before I'd spend several hundred dollars for some
of the hardware solutions which have been mentioned.
