What happens when an EC2 instance is restarted?
When you restart an instance, it retains its public (IPv4) DNS name, public and private IPv4 address, IPv6 address (if applicable), and any data on its instance storage volumes. Restarting an instance does not start a new instance billing period (minimum one minute charge), unlike stopping and starting your instance.

How do I recover my EC2 instance?
You can create an Amazon CloudWatch alarm that monitors an Amazon EC2 instance and automatically recovers the instance if it becomes damaged due to underlying hardware failure or an issue that requires AWS involvement for repair. Terminated instances cannot be recovered.
Is EBS data deleted on every reboot?
If it was an EBS volume, the data would not have disappeared. If it was an instance store, simply restarting the instance would not have lost your data. So it’s a mystery why/how it disappeared. Regardless, there is a way to recover the data unless you are using EBS and have taken a snapshot previously.
What happens to your data when an EC2 instance is stopped?
As part of terminating an Amazon EC2 instance, data is deleted from any instance store volumes associated with that instance. By default, the Amazon Elastic Block Store (Amazon EBS) root volume is automatically deleted. You can then access the data contained on those volumes.
Why was my EC2 instance terminated?
Amazon EC2 Auto Scaling terminates Spot Instances when any of the following occurs: Capacity is no longer available. The spot price exceeds the maximum price you specified for the instances.
Is instance storage faster than EBS?
Performance. EBS-backed AMIs launch faster than EC2 instance store-backed AMIs. However, the performance of an instance that uses an EBS volume for its root device is slower for a short time while the remaining parts are retrieved from the snapshot and loaded onto the volume.
Why did my EC2 instance stop?
The following are the most common reasons: The instance failed one or both health checks. The underlying hardware hosting your instance was faulty, and Amazon EC2 rebooted your instance to move it to new, healthy hardware. A user or application within your server restarted the instance.
Why did my Amazon EC2 instance restart?
1 The instance failed one or both health checks. 2 The underlying hardware hosting your instance was faulty, and Amazon EC2 rebooted your instance to move it to new, healthy hardware. 3 Scheduled maintenance was performed on your instance that required a restart. 4 A user or application within your server restarted the instance.
What happens when you stop an EC2 instance?
Note that if your instance is backed by an instance store or has instance store volumes that contain data, the data will be lost when you stop the instance. For more information, see Determine the root device type of your instance. If you launch instances with EC2 Auto Scaling, stopping the instance might terminate the instance.
What happens when I restart my Elastic Compute Cloud instance?
An instance reboot is equivalent to an operating system reboot. In most cases, it only takes a few minutes to restart your instance. When you restart an instance, it stays on the same physical host, so your instance keeps its public (IPv4) DNS name, private IPv4 address, IPv6 address (if applicable), and any data on its instance storage volumes.
How can I retrieve my data from AWS?
If you can repair the file system, you can recover your data from the volumes in the file system, as follows: Power off your virtual machine and use the AWS Storage Gateway Management Console to create a recovery snapshot. This snapshot represents the most current data stored in AWS.
