Types of Amazon DLM policies. In this section, we're going to go over what is a data lifecycle policy, and the different types of lifecycle policies available. First, what is a lifecycle policy? A policy is a set of rules and attributes assigned to a specific resource or resources that define the snapshot process. From what type of resources to create a snapshot from, when to create the snapshot or backup, to how long those snapshots should be retained. There are three types of policies that can be created: EB S snapshot policy, EB S-backed AMI policy, and a cross-account copy event policy. Let's talk about each one of those and define them.

EB S snapshot policy is specific to only EB S volumes and snapshots. EB S-backed AMIs include a snapshot for each volume that's attached to a source or golden image of the instance. And cross-account copy event policy allows you to copy your Amazon EB S snapshots to a specific AWS region. Enabling you to protect yourself from data loss that includes being compromised or to implement disaster recovery. Now this concludes the types of Amazon data lifecycle policies.
