About backups of Lotus database links and directory links
The agent only backs up database files with *.nsf, *.ntf, and *.box extensions in the directories that are specified in the backup selections list of the policy. The agent does not automatically follow database links or directory links to the actual databases.
To correctly back up linked databases or linked directories outside of the Domino data directory, in the backup selections list add the following:
The directory containing the Lotus Notes databases
The directory containing the database link (.nsf file)
OR
The directory containing the directory link (.dir file)
