Unfortunately, It's a feature of MongoDB
copy the files in your database directory itself (default /data/db) rather than using mongodump/mongoresotre. If you can shut down your database for periods of time, this is best. Otherwise, you have to use file system snapshots or similar. See this for more the official mongo blurb: http://docs.mongodb.org/manual/core/backups/ |

如果是 replica set 模式，可以搞出来一个 secondary 然后移花接木
