BASH – backup sites and MySQL databases on AWS S3

The script finds all folders in a given directory and archives them one by one, copies them to S3 Bucket and deletes them locally. It also receives a list of all MySQL databases, excluding system databases, archives them in turn, sends them to S3 Bucket and deletes them locally.

#!/bin/bash

DATE=$(date +%d-%m-%Y)
WEB_PATH="/var/www/html/"

SITE_LIST="$(ls $WEB_PATH)"
DB_LIST="$(mysql -u root -e "SHOW DATABASES;" | grep -Ev "(Database|information_schema|performance_schema|mysql|sys)")"
S3_BUCKET="s3://artem-services"
