Use this function to copy a database from a remote to the current database. The command assumes that the remote database has the same name as the current database. For example, to clone a database named importdb on a host named hostname, do
use importdb
db.cloneDatabase("hostname");
New databases are implicitly created, so the current host does not need to have a database named importdb for this command to succeed.
This function provides a wrapper around the MongoDB database command “clone.” The copydb database command provides related functionality.
