What happens to references to duplicate files stored in an online backup
directory, as well as ones stored in a remote backup
location?  In more complicated versions of this question,
how would a federated archive handle replicas stored
in other archives?

Then, would it matter if the archive decided to do a slight
reformat of the data that merely rearranged the numerical
values without adding or deleting any of them?
