What’s the easiest way to back up EC2 instances automatically?
I have an EBS-backed Amazon EC2 instance. I would like to create a daily backup schedule, and keep, say, a week's worth of daily backups, plus a few older images (from 2,3,4 weeks ago). I don't mind creating the backups on the fly, with the snapshot mechanism, but I would like an easy wrapper to manage it for me.
What is the simplest way to set this up? How much would this cost me, for a micro instance?
