When an EC2 instance that is backed by an S3-based AMI is terminated, what happens to the data on the root
Data is automatically saved as an EBS snapshot.
Data is automatically saved as an EBS volume.
Data is unavailable until the instance is restarted.
Data is automatically deleted.
Using the legacy S3 based AMIs, either of the above terminates the instance and you lose all local and
ephemeral storage (boot disk and /mnt) forever. Hope you remembered to save the important stuff elsewhere.
