Ummmmm, if you try to archive regular files when the database is active, you *will* have an inconsistent snapshot of the database. Do you perform these backups only when the engine is offline? I can't see this being safe on any brand of engine if the database is "twinkling". The only way to get a consistent (ie logical instant in time) backup of a live, active database is to use a tool which maintains the illusion on your behalf. Received on Tue Apr 13 2004 - 19:45:29 CDT
