Mongo Dump S3

What can it do ?

A utility to backup/dump mongo database to amazon s3

How do I get set up?

• Install the package npm install mongodb-dump-backup-aws-s3
• Import it into your file
• Setup a backup client with your aws credential
• Initiate the backup

Notes about the generated dump

The generated mongo dump is an archive, so while restoring you should mark the --archive flag on

mongorestore --archive=/path/to/dump

Working example:

const mongoS3Backup = require("./index");
const dotenv = require("dotenv");
const moment = require("moment");
dotenv.config(".env");

const bucketName = process.env.AWS_S3_DUMP_BUCKET;
const accessKey = process.env.AWS_ACCESS_KEY_ID;
const accessSecret = process.env.AWS_SECRET_ACCESS_KEY;
const dbConnectionUri = process.env.MONGO_URI;

const backupClient = mongoS3Backup({ bucketName, accessKey, accessSecret });
const date = moment().format("MMMM Do HH-mm");

backupClient
.backupDatabase({ uri: dbConnectionUri, backupName: "test_backup_" + date })
.then((response) => {
  console.log("Success response ", response);
  /*
  Success response includes default aws response to uploading files
  example: 
    { 
      ETag: '"exampleEtag"',
      Location: 'https://examplebucket.s3.amazonaws.com/test_backup',
      key: 'test_backup',
      Key: 'test_backup',
      Bucket: 'mybucket' 
    }

*/
})
.catch((err) => {
  console.log("error is ", err);
});

Possible options passed to backupDatabase method

• uri: string required the connection string for the mongo database `
• backupName: string required the name of the backup to be dumped on s3
• gzip: true|false wheather to use gzip option for the dump command, defaults to false

The package supports both promises & callback patterns
