Amazon EBS provides the ability to create snapshots (backups) of any Amazon EBS volume. It takes a copy of the volume and places it in Amazon S3, where it is stored redundantly in multiple Availability Zones.
The first snapshot is a full copy of the volume; ongoing snapshots store incremental block-level changes only.This is a fast and reliable way to restore full volume data.
Your EBS snapshots and AMI's are stored in Amazon S3. However, you won't find your snapshots in any of your S3 buckets.
AWS uses the S3 infrastructure to store your EBS snapshots, but you cannot access them while they reside in S3.
CloudRanger simply allows you to manage your AWS experience more easily.
