Copying a DatabaseΒΆ
To copy a database within a single mongod process, or between mongod
servers, simply connect to the target mongod and use the
command()
method:
>>> from pymongo import MongoClient
>>> client = MongoClient('target.example.com')
>>> client.admin.command('copydb',
fromdb='source_db_name',
todb='target_db_name')
To copy from a different mongod server that is not password-protected:
>>> client.admin.command('copydb',
fromdb='source_db_name',
todb='target_db_name',
fromhost='source.example.com')
If the target server is password-protected, authenticate to the “admin” database first:
>>> client.admin.authenticate('administrator', 'pwd')
True
>>> client.admin.command('copydb',
fromdb='source_db_name',
todb='target_db_name',
fromhost='source.example.com')
See the authentication examples.
If the source server is password-protected, use the copyDatabase function in the mongo shell.
Versions of PyMongo before 3.0 included a copy_database
helper method,
but it has been removed.
