Exactly.  Webster defines backup as simply "a copy of computer data".

I use the simplest backup strategy known to man... I copy my "important"
recordings to an external drive that is only powered on long enough to
perform said backup.  I run a script based on rsnapshot, so I can do some
recovery of deleted files (something that a raid array cannot do).  Can't
get any more basic.  But it means that if one of my recording drives fail,
I don't have to tell my wife that I lost an entire season of her favorite
show.

Simple, and cheap... and actually fast compared to some solutions.
