Now the initial/default value is 1 indicating only one copy of data.
Would nr_copy be more accurate?

Well, it's at least shorter; the problem is that it's not really
another "copy" of the data, it's just that it can simply be different
(multiple) ways of reconstructing the data.  I suppose we could say
that it's a virtual copy.

In any case, I can't think of a better term, so nr_copy is probably as
good as any.
