>Actually, the entire database is called $Sharepoint--not just those two categories. So you are saying that the client's data belongs in the System group? If so, why isn't Copy Database an option? I guess that doesn't matter because I can't access the SQL 7 database from there anyway.

Above 'System Databases' in the tree is 'Databases'. If you right click on 'Databases' you can create a new database, Attach a database, or restore a database.
