This script is used to automate the backup process of your mongodb instance. It's a very easy bash script and variables are provided for customization to script. If you don't know how to use mongodump, I suggest you start [here](https://docs.mongodb.com/manual/reference/program/mongodump/)

MONGO_DATABASE="your_db_name"
APP_NAME="your_app_name" #this is optional.Use this if you have more than 1 scripts for more than 1 app
MONGO_HOST="<db_name>/server0.example.com:27011,server1.example.com:27011,server2.example.com:27011" #for replica set config
#MONGO_HOST="127.0.0.1" in case running a standalone server
#MONGO_PORT=27001 in case running a standalone server on a port other than 27017
