Scheduled backup for MongoDB
May 29, 2015
MongoDB is one of NoSQL pioneers and it has a great community. Nowadays, most of startups prefer to use MongoDB as the main database because of its simplicity. Configuring scheduled backup for a database is really important to keep the last updated data somewhere and restore it in case of database crash.
In this post I want to introduce a simple open-source tool that I’ve recently published to setup a minimal scheduled backup for MongoDB.
Dependencies
I built this tool using Node.js so first of all you need to install http://nodejs.org/. I will publish a binary version for all platforms soon.
You need no more dependencies but official Node.js module. In the next step we will install them using npm.
Install
I named this tool mongodb-backup and you can clone the repository from Github:
Then go to the folder of project and run following command:
npm install
This command installs all required dependencies including AWS sdk.
Configuration
This tool has a simple config.js file that defines all dependencies to run the mongodump command and upload it to the Amazon S3 storages. Here you can find a list of all dependencies: https://github.com/afshinm/mongodb-backup#configjs
Go go go
Final step is to run the script. You can run the cronjob using following command:
node index.js start
And if you want to run the script as a deamon, install forever using npm install forever and then run this command:
forever start index.js start
Conclusion
This version of mongodb-backup works with Amazon S3 but I will publish another version soon that accepts FTP and SFTP to transfer backup files.
