MongoDB Backups Using Amazon S3
Good help from Sunil Arora for those looking to backup MongoDB installations:
Though we have all the real-time replication mechanism in place but we wanted to take offsite backup for some section of user data in another place and we decided to go with Amazon S3 service. I thought of shareing some of the code snippets here because I think there are lot of foIks who could make use of this and save their time. So, rest of the blog discusses steps for backing up data from MongoDB, storing it to Amazon S3 store and then restoring back from Amazon S3.
