backup-mongodb
==============

This module will backup mongodb into .json files, archive it into .zip file that is then send to provided emil address using nodemailer automatically

Motivation
==========

I wrote this module as a simple straight forward module for backing up mongodb. I also realized that I need the backup file in an external environment other than the server (which of course is the essence of backup). Thus, I added the feature to zip the output .json files and then send them to an email using 
[nodemailer](https://github.com/nodemailer/nodemailer).
From the email, I can access the files and use them for restoration anytime later.

The backup output files are named in the format
dbName_day_month_year.hour.mins.second
e.g. test_21_9_16.4.33.0


This makes it easy to know which file is the latest backup and for reference sake


After using this module to create a backup, you can use the accompanying module 
[backup-mongodb-restorer](https://github.com/SeunMatt/backup-mongodb-restorer) to restore the .zip file to the database

Please read on to get full understanding of how it works.

Installation
============
> npm install -save backup-mongodb


Usage Example
==============

Without Email Configuration
---------------------------

~~~javascript

var dbUri = "mongodb://127.0.0.1:27017/test";

//example dbUri with username and password for the database test
// var dbUri = "mongodb://username:pwd@127.0.0.1:27017/test";


var basePath = "./backup";
var Backup = require("backup-mongodb");

new Backup(dbUri, basePath).backup();

//optionally you can call new Backup(dbUri, basePath).backup(done);
//where done is the callback to be called when done

~~~

With Email Configuration
------------------------

~~~javascript

var dbUri = "mongodb://127.0.0.1:27017/test";

//example dbUri with username and password for the database test
// var dbUri = "mongodb://username:pwd@127.0.0.1:27017/test";


var basePath = "./backup";
var Backup = require("backup-mongodb");

//========= email configs ========

var emailSubject = "DATABASE BACKUP"; 
var emailText = "This email contains an attachment of the backup of your mongodb in zip format";

var smtpOptions = {
 	host: "your.mailserver.hostdomain.com",
	port: "the port on which your mail server is running",
	auth: {
		user: "your.username@your.mailhost.com",
		pass: "your password for the email user above"
	   },
	tls : { 
		rejectUnauthorized: false,
		secureProtocol: "TLSv1_method"
		}
	};


	var emailOptions = {
		from: "sender.email@something.com",
		to: "receiver.email@something.com",
		subject: emailSubject,
		text: emailText
	}

//======== now do the backup ==========

new Backup(dbUri, basePath, smtpOptions, emaiOptions).backup();

//optionally you can call new Backup(dbUri, basePath, smtpOptions, emaiOptions).backup(done);
//where done is the callback to be called when done
