Amazon Data Lifecycle Manager

Section titled “Concept”Amazon Data Lifecycle Manager (DLM) automates the work of EBS snapshots. A snapshot is a backup copy of an EBS volume at a specific point in time. In DLM you create a lifecycle policy, which uses tags to decide which volumes or instances get snapshots. The policy says how often to take a snapshot and how many to keep, or for how long. It can also automate creating and cleaning up EBS-backed AMIs (server templates).
Simple example
Section titled “Simple example”A phone’s auto backup — photos are backed up on their own every night, and old backups are deleted after a while.
