Does Amazon support any kind of automatic scheduled snapshots that can be configured for each single AMI/EBS?
my goal is to have each AMI backup itself regularly without
AWS Management Console doesn't have a built-in automation for creating an maintaining EBS snapshots. You may try using scripts, third party cloud managment consoles with basic autommation of EBS snapshots or dedicated snapshot-based backup and recovery management solutions for EC2 instnaces & EBS volumes, available on the AWS marketplace or elsewhere.
