Using Online Backup

You can create a copy of the current state of a database without quiescing the database or shutting down any of the database’s processes. To do this, use the nuodbmgr command line utility to invoke the hotcopy command.

Hot copy is a mechanism for copying a database’s archive and journal from one of the database’s running storage managers (SM) or from the database's snapshot storage manager (SSM) if the database has one. The advantage of a hot copy is that it is an online procedure. Your database remains running and available during the hot copy operation. This is the case even for a single host database.
