Repeating my last post in this conversation...
The only problem is that *in this case* - the backup copy you are allowed to
make is not being used as backup copy - but is in actual use. In other
words - the copy is not for archival purposes.
Title 17, Chapter 1, 117: Limitations on exclusive rights: Computer programs

( or:

Specifically:
(a) Making of Additional Copy or Adaptation by Owner of Copy —
Notwithstanding the provisions of section 106, it is not an infringement for
the owner of a copy of a computer program to make or authorize the making of
another copy or adaptation of that computer program provided:
(1) that such a new copy or adaptation is created as an essential step
in the utilization of the computer program in conjunction with a machine and
that it is used in no other manner, or
(2) that such new copy or adaptation is for archival purposes only and
that all archival copies are destroyed in the event that continued
possession of the computer program should cease to be rightful.
The part that should be of interest to this conversation is, "... for
archival purposes only ...".
Of course - this assumes you are speaking of U.S. Copyright material.
