EC2 terminated without snapshot

Double check if you have AWS Backups in place or EBS Life cycle manager setup. You may find you have a backup of the EC2.

Apologies for your loss. To prevent future instances of accidental data loss on your EC2 instance, it's advisable to activate Termination Protection. By default, when an EC2 instance is terminated, its attached EBS volumes are also deleted, leaving no way to retrieve your data.

Restoring an EC2 instance that was terminated without a snapshot can be challenging, as AWS EC2 instances do not automatically back up your instance or volume data. Once an EC2 instance is terminated, its associated physical storage (EBS volume) is also deleted if the "Delete on Termination" flag is set to true, which is the default behavior for the root device volume.
