- How do EBS snapshots work and how can you use them to move data to another AZ or Region?
A snapshot is a point-in-time backup of an EBS volume, stored in S3-managed storage. After the first full copy, later snapshots are incremental. You can create a new volume from a snapshot in any AZ of the Region, or copy the snapshot to another Region.

Automated backups are taken daily with transaction logs, support point-in-time restore within a retention period of up to 35 days, and are removed with the instance. Manual snapshots are taken on demand and stay until you delete them.
