When I first started working in the early 80s I worked with an operations manager who had started when Turing was a boy and his view was it didn't matter what you did with backups so long as you verified them. At last then you would be certain that you had something to restore should the need arise. Admittedly in those days, media was much more unreliable, which was his main concern, but it still seems good advice as it would pick up corrupt files or archives as well - and did for me last year when I had a bad DVD.
