Automating EC2 EBS Snapshot Cleanup
http://www.techkismet.com/systems-admin/automating-ec2-ebs-snapshot-cleanup.html
So the problem in a nutshell is I have 10 volumes, each of which is cron’ed to be snapshotted at various times of the day (depends on the specific volume as to how often it is backed up). With 10 volumes, my S3 storage costs can get out of hand quite quickly. So I needed to develop a set of scripts that would scan my snapshots – and remove the oldest ones – so I’m not paying for that storage.
