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. -- "People only see what they are prepared to see." -Ralph Waldo Emerson
