Those postings are good suggestions, based upon real experiences.

Alas, the case cited is not in a network phase: it is plowing through the
file system looking for candidate objects.  The poster indicates having gone
through our list of common causes for slow backups, and not having found a
match based upon his analysis; so we'll have to await the results from his
client trace or other analyses.
