Introduction to MongoBack

MongoBack is a powerful and flexible backup and restoration solution designed for MongoDB databases. It provides robust API functionalities to help developers effectively manage their data. In this article, we explore dozens of useful MongoBack APIs with code snippets to give you an in-depth understanding of this tool.

Key MongoBack APIs

1. Initialize Backup

This API initializes a new backup process.

const mongoBack = require('mongoback');

const backupOptions = {
  uri: 'mongodb://localhost:27017/mydatabase',
  backupDir: '/backups',
  archiveName: 'backup.tar'
};

mongoBack.initBackup(backupOptions)
  .then(() => {
    console.log('Backup initialized successfully.');
  })
  .catch(err => {
    console.error('Error initializing backup:', err);
  });

2. Start Backup

This API starts the backup process.

mongoBack.startBackup()
  .then(() => {
    console.log('Backup started successfully.');
  })
  .catch(err => {
    console.error('Error starting backup:', err);
  });

3. List Backups

This API lists all backups available in the specified directory.

mongoBack.listBackups('/backups')
  .then(backups => {
    console.log('Available backups:', backups);
  })
  .catch(err => {
    console.error('Error listing backups:', err);
  });

4. Restore Backup

This API restores a backup from a specified archive.

const restoreOptions = {
  uri: 'mongodb://localhost:27017/mydatabase',
  backupDir: '/backups',
  archiveName: 'backup.tar'
};

mongoBack.restoreBackup(restoreOptions)
  .then(() => {
    console.log('Backup restored successfully.');
  })
  .catch(err => {
    console.error('Error restoring backup:', err);
  });

App Example Using MongoBack APIs

Below is an example of a simple Node.js application that demonstrates the usage of the APIs discussed above.

const express = require('express');
const mongoBack = require('mongoback');
const app = express();

const backupOptions = {
  uri: 'mongodb://localhost:27017/mydatabase',
  backupDir: '/backups',
  archiveName: 'backup.tar'
};

app.get('/backup', (req, res) => {
  mongoBack.initBackup(backupOptions)
    .then(() => mongoBack.startBackup())
    .then(() => res.send('Backup completed successfully.'))
    .catch(err => res.status(500).send('Error during backup process: ' + err));
});

app.get('/restore', (req, res) => {
  mongoBack.restoreBackup(backupOptions)
    .then(() => res.send('Restore completed successfully.'))
    .catch(err => res.status(500).send('Error during restoration process: ' + err));
});

app.get('/list-backups', (req, res) => {
  mongoBack.listBackups('/backups')
    .then(backups => res.send(backups))
    .catch(err => res.status(500).send('Error listing backups: ' + err));
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

In this application, users can initiate a backup, restore a backup, and list all available backups through different endpoints.
