db.cloneDatabase()

db.cloneDatabase("hostname")
Parameters:
  • hostname (string) – Specifies the hostname to copy the current instance.

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 commandclone.” The copydb database command provides related functionality.
