Definition of BCV

Could someone explain to me what the acroymn BCV means and how it is applied with an SQL database?
ThanksYou probably mean BCP, the Bulk Copy Program provided as a SQL Server utility with the SQL client tools.

You might actually mean BCV if you are using EMC storage, in that context it means Business Continuation Volume.

-PatP|||Thanks Pat for the response ... I did mean Business Continuation Volume because our client is using EMC storage. Can you explain to me what this actually is and how it is benefical as a tool to use?|||http://www.emc.com/products/product_pdfs/pdg/timefinder_pdg.pdf?emccomjsessionid=23057310987216 72334|||Actually, EMC does a better job explaining (http://www.emc.com/pdf/business_centers/windows/Microsoft_SQL.pdf) how to use BCVs with SQL Server than I can. We've never gotten them to work to my satisfaction.

The basic idea is that a BCV will allow you to mirror data in real time. In SQL 7.0 hooks were added, which were refined in SQL-2000 to allow an application to "freeze" a disk volume. This freeze would effectively flush the disk buffers to disk as of a specific point in time, almost as though the database had been stopped (to detach it). The theory is that you could mirror a BCV volume to a production volume, freeze the SQL files, break the mirror, then "thaw" the SQL files again, all without the end user knowing or caring that anything had ever happened.

Anywho, see the EMC document for a better description. While I love EMC in general, we (my firm working with EMC) were never able to make BCVs work in production.
