AWS infrastucture -remove geographic restriction and create backup procedure

We have an odoo12 ERP hosted on AWS
This ERP is a multidomain application
All domains are registered with AWS Route 53 and redirected to EC2
hhandpartners.com
hhdecisive.com
opex.academy
altissima.co.uk
winesquare.it
the sys also has a https certificate from aws that must be used
-------------------
TASK 1 all domains must be reachable both form www.domainname.extension and domainname.extension
currently because of a mistake in the configuration some of them are reachable only form domainname.extension
please note that this task may involve a knowledge of odoo12 not only of AWS
----------------
TASK2 remove the geographic restriction that is impacting on SEO positioning
----------------
TASK3 create a manual backup-restore procedure that we can handle directly
