When you create an Amazon Machine Image (AMI) in AWS, it includes one or more EBS snapshots—each representing a copy of the volumes attached to the EC2 instance at that moment.
🧠 Here's how it works:
- Each AMI creation results in one snapshot per EBS volume attached to the instance.
- These snapshots are stored in Amazon S3 (behind the scenes) and are incremental, meaning:
- The first snapshot is a full copy.
- Subsequent snapshots only store changes since the last one, saving space and cost.
In AWS, EFS stands for Amazon Elastic File System—and it’s a powerhouse when it comes to scalable, shared file storage.
