#!/bin/bash
# This will create a full db dump and store it to s3 bucket my-db-backup-bucket in folder full-db-backup
# You can modify all variables as you wish
# Here we are making dump to /data/database-backup/ make sure that the directory is there.
# Here we're not keeping dumps locally.

echo "Enter DB name: "
read db

rm -rf /data/database-backup/*

Details added here.

You can replace:

echo "Enter DB name: "
read db

By:

read -p "Enter DB name: " db

It's nicer and in case you have a script with several times questions to ask, it stays cleaner that way.
