About excluding Lotus Notes databases from backups
You can exclude specific Lotus Notes databases from the backup by using database links and directory links. This method works if the databases to which the links point are located outside of the Domino data directory.
Identify the databases you want to exclude and move them to a directory outside the Domino data path. Then, create a Domino d atabase or a directory link to the databases. The agent only backs up files with extensions .nsf, .ntf and .box, and does not follow database links or directory links.
