That reminds me of the scene in The Court Jester where a knight pushes
Danny Kaye out of the spot where lightning is about to strike.  :-))
Our reality is that we don't know where lightning is about to strike.
You don't know that a tape and its contained data are actually good
until you really need it.  That's why we increase the odds by making
copy storage pool tapes, and why one really needs to keep multiple
generations of DB backup tapes and a Reusedelay long enough to cover
all of them.  Tape is tape, operators are operators, and the random
elements of this universe jump out of dark recesses to surprise and
humble us when we believe we've thought of everything.
Be cautious, and increase your odds.
