Recover terminated EC2 Instance

问题:

title says it all. I inadvertently terminated an EC2 Instance and desperately need to restart it/relaunch it!!! Any help? It would be disastrous if I had to start all over!! Does anyone know how I can fix this?

Basically it goes like this:

• Your machine is gone, you cannot restart, you need to create a new instance
• all the data you had on an instance store volume are gone (you cannot recover those)
• If you had EBS Volume attached and you had setting enable for 'delete on termination' the latest data are gone. You can recover if you have a snapshot from this volume.
• If you had EBS Volume attached without flag for 'delete on termination' you can recover those data

So what you can do:

• check your snapshots and Volumes in the ec2 console. If you have no snapshot/volumes, you cannot recover anything
• if you have root volumes,
  • make a snapshot of those you want to recover
  • from the snapshot, make an image
  • from the ami, launch a new instance for the specific image you've just created
• if you dont have root volumes
  • create volumes from snapshot if you have any snapshot you need to recover data
  • create a new ec2 instance
  • attach and mount the volumes to the new instance
  • read and backup your data
