backup-mongo-to-s3

A module that makes database backup and uploads to s3.

INTRODUCTION

This module involves the following steps.

1. Make DB backup on disk.
2. Make a zip file out of localbackup.
3. Delete the local-backup directory.
4. Upload the zip file to s3.
5. Delete zip file, if 'keepLocalBackups' parameter is not set to true.
6. Delete outdated cloud backup zip files, outdated refers to zip files older than the latest 'noOfTotalBackups'.

USAGE

1. Require the module.
2. Use the init method to pass argument object.
3. Use the start method to start the process.
4. Compatible with cron-job to schedule backup-process.
