Overview of this book

MongoDB is a high-performance and feature-rich NoSQL database that forms the backbone of the systems that power many different organizations – it’s easy to see why it’s the most popular NoSQL database on the market. Packed with many features that have become essential for many different types of software professionals and incredibly easy to use, this cookbook contains many solutions to the everyday challenges of MongoDB, as well as guidance on effective techniques to extend your skills and capabilities. This book starts with how to initialize the server in three different modes with various configurations. You will then be introduced to programming language drivers in both Java and Python. A new feature in MongoDB 3 is that you can connect to a single node using Python, set to make MongoDB even more popular with anyone working with Python. You will then learn a range of further topics including advanced query operations, monitoring and backup using MMS, as well as some very useful administration recipes including SCRAM-SHA-1 Authentication. Beyond that, you will also find recipes on cloud deployment, including guidance on how to work with Docker containers alongside MongoDB, integrating the database with Hadoop, and tips for improving developer productivity. Created as both an accessible tutorial and an easy to use resource, on hand whenever you need to solve a problem, MongoDB Cookbook will help you handle everything from administration to automation with MongoDB more effectively than ever before.

Back up and restore data in Mongo using out-of-the-box tools


In this recipe, we will look at some basic backup and restore operations using utilities such as mongodump and mongorestore to back up and restore files.

Getting ready

We will start a single instance of mongod. Refer to the recipe Installing single node MongoDB in Chapter 1, Installing and Starting the Server, to start a mongo instance and connect to it from a mongo shell. We will need some data to backup. If you already have some data in your test database, that will be fine. If not, create some from the countries.geo.json file available in the code bundle using the following command:

$ mongoimport  -c countries -d test --drop countries.geo.json

How to do it…

  1. With the data in the test database, execute the following (assuming we want to export the data to a local directory called dump in the current directory):

    $ mongodump -o dump -oplog -h localhost -port 27017
    

    Verify that there is data in the dump directory. All files will be ...
