Write Database backup scripts

[Liopun]

Avoid data loss in case of node failures or human errors.

Writing scripts for database backups is fairly simple. You can use Mongoexport to export collections as JSON or CSV, or Mongodump to dump the whole database.

You may use node-cron or node-schedule npm libraries for running cron jobs to take timely database backups.

You may create a folder named scripts in the root folder and add your script to that. That script will be run independent of this server to avoid performance issues.
