At this point, Ted sunk into his chair and sighed. He quickly calculated that, for any given one-week period, there would have no less than sixteen copies of the entire database for any given night on any of sixteen tapes. Over the space of one week, there would be no less than one hundred and twelve complete backups of the database stored on tape, sixteen complete backup copies stored on disk, and four live copies on the four main servers. That came to a grand total of 132 copies of the database with data no more than one week old.
