Mongo Backup to S3

Easily stream mongodb backups to S3

Motivation

Explore an inexpensive way to backup your MongoDb databases

Get Started

Setup an S3 bucket, run this in a cron job using a Heroku Single Dyno (worker)

Install

npm install mongo-backup-to-s3

Example:

var mongoBackup = require('mongo-backup-to-s3');

var config = {
    mongodb:{
        url: process.env.MONGO_URL
    },
    s3:{
        bucket:'mybucket',
        folder:'backups',
        key: process.env.AWS_ACCESS_KEY,
        secret: process.env.AWS_SECRET_KEY
    }
};

mongoBackup.dumpToS3(config);

Generated filename in S3: backups/mongo_2015-12-30_22-16-34_mydatabase.dmp

Dependent modules

This module relies heavily on mongo-dump-stream so it can output the 'dump' to a stream, and so we don't have to use mongodump (which requires a child process).
