Just to be clear, for everyone.

NBackup has many 'modes', those are:

1 - Ability to set the physical database file into a state which allows
for OS level copy and backup utilities to run against the LIVE database.

2 - Full/Image physical backup functions of LIVE, at hardware speeds.
This provides the 'clone copy' functionality. This can be redirected to
tape devices.

3 - Incremental/differential (multi-level) backups, of LIVE databases,
again at hardware speeds.

Further, NBackup can be launched via command-line tool OR SQL (ALTER
DATABASE ...) syntax.
