This tutorial describes the process for Auto Backup MongoDB Database with NodeJS on server.

Prerequisites:

  • Fs and lodash npm modules are installed.
  • Make sure that your mongodb is protected with username and password, if not than follow steps from below link.

Key Summary

  • Overview: The article explains how to implement an automated backup system for MongoDB databases using Node.js, ensuring data safety and recovery on servers.
  • Key Features: Automation Script: Uses Node.js to schedule and automate MongoDB backups with tools like mongodump. Scheduling: Integrates with libraries like node-cron to run backups at specified intervals (e.g., daily, weekly). Storage Options: Saves backups to local servers, cloud storage (e.g., AWS S3, Google Cloud Storage), or other remote locations. Compression: Compresses backup files to save storage space using tools like tar or zip. Error Handling: Implements logging and notifications (e.g., via email or Slack) to alert administrators of backup failures.

Step 1

Create a js file in your project folder called mongodb_backup.js and add below code.

Replace variables < databaseUsername >, < databasePassword >, < databaseName > , < serverPath > with the values of your database.

var fs = require('fs'); var _ = require('lodash'); var exec = require('child_process').exec; var dbOptions = { user: '', pass: '', host: 'localhost', port: 27017, database: '', autoBackup: true, removeOldBackup: true, keepLastDaysBackup: 2, autoBackupPath: '' // i.e. /var/database-backup/ }; /* return date object */ exports.stringToDate = function (dateString) { return new Date(dateString); } /* return if variable is empty or not. */ export.empty = function(mixedVar) { var undef, key, i, len; var emptyValues = [undef, null, false, 0, '', '0']; for (i = 0, len = emptyValues.length; i < len; i++) { if (mixedVar === emptyValues[i]) { return true; } } if (typeof mixedVar === 'object') { for (key in mixedVar) { return false; } return true; } return false; }; // Auto backup script dbAutoBackUp: function () { // check for auto backup is enabled or disabled if (dbOptions.autoBackup == true) { var date = new Date(); var beforeDate, oldBackupDir, oldBackupPath; currentDate = this.stringToDate(date); // Current date var newBackupDir = currentDate.getFullYear() + '-' + (currentDate.getMonth() + 1) + '-' + currentDate.getDate(); var newBackupPath = dbOptions.autoBackupPath + 'mongodump-' + newBackupDir; // New backup path for current backup process // check for remove old backup after keeping # of days given in configuration if (dbOptions.removeOldBackup == true) { beforeDate = _.clone(currentDate); beforeDate.setDate(beforeDate.getDate() - dbOptions.keepLastDaysBackup); // Substract number of days to keep backup and remove old backup oldBackupDir = beforeDate.getFullYear() + '-' + (beforeDate.getMonth() + 1) + '-' + beforeDate.getDate(); oldBackupPath = dbOptions.autoBackupPath + 'mongodump-' + oldBackupDir; // old backup(after keeping # of days) } var cmd = 'mongodump --host ' + dbOptions.host + ' --port ' + dbOptions.port + ' --db ' + dbOptions.database + ' --username ' + dbOptions.user + ' --password ' + dbOptions.pass + ' --out ' + newBackupPath; // Command for mongodb dump process exec(cmd, function (error, stdout, stderr) { if (this.empty(error)) { // check for remove old backup after keeping # of days given in configuration if (dbOptions.removeOldBackup == true) { if (fs.existsSync(oldBackupPath)) { exec("rm -rf " + oldBackupPath, function (err) { }); } } } }); } }

Step 2

To create cron install cron module from NPM package manager https://www.npmjs.com/package/cron using below command

npm install cron –save

Add below code into your server.js / main.js / index.js

global.CronJob = require(‘Your path to cron.js file’);

How to Hire Remote Developers Without Losing Code Quality: A 2026 Playbook for CTOs

Every CTO who hires remote developers eventually asks the same question: how do I know this is going to work before I've sunk three months and a sprint's worth of technical debt into finding out? Most guides to hiring remote developers answer a different question: which platform to use. They skip the part that actually determines whether the code that comes back is any good. This playbook covers the vetting mechanics, engagement models, and real rate data behind hiring remote engineers who ship production-quality code from week one, not another list of freelance marketplaces.
