Interesting.  This may be one of those things were multiple people have
multiple definitions for the same terms.  I usually hear a cold site
referenced as an equipped site capable of becoming a primary production
site in the shortest time possible.  So, the minimum configuration
necessary to support production, and probably using something like EMC's
SRDF, or Veritas' Replicator to mirror data from the primary site.

We may have misinterpreted his initial question though.  He asked about
hot site backup versus cold site backup.  It's possible he's inquiring about
the difference between doing a hot backup on a live database, as opposed
to stopping the database to do a backup.
