I want to clone a collection to a backup collection, before processing all the entries in it through my Spring controller.
On searching, I came to know about various ways to do so through terminal. There is also a possibility to use executeCommand menthod to directly execute mongodb commands (copyTo command in my case). But again, I could not find a way to do so.
Could somebody please provide me any pointers on this?
you can setup JMX support to your project: http://static.springsource.org/spring-data/data-document/docs/current/reference/html/ , see "Chapter 10. JMX support" section, you will be able to get an administrative MBean, MongoAdmin which will let you perform administrative operations such as drop or create a database, and execute one of your solution candidates, like execute mongodump(http://docs.mongodb.org/manual/reference/mongodump/#cmdoption-mongodump--collection) and mongorestore(http://docs.mongodb.org/manual/reference/mongorestore/#cmdoption-mongorestore--collection) for a simgle collection, during restoration you can indicate the new collection name.
