nBackup will set the database file in such a mode, that the database server
knows it's being backed up at the level of a page-for-page copy (or delta).

The server then will stop modifying the database file and keep any
modifications
in a special file.

After nBackup has finished, it will notify the server, which will update the
database file and continue normal execution.

This makes nBackup much faster than a "logical backup", like gbak does,
which reads all data from the database by plain SQL.
