Take a Snapshot of Running Server On Amazon Cloud
If you want to do perform some tasks on the running server, So it’s better you have a snapshot of the running server before it. you can restore ec2 snapshot in aws.
If something goes wrong, you can restore the server using this snapshot. I have run a webserver and will take a snapshot.
EC2 -> Elastic Block storage –> snapshots
Click on create a snapshot
Copy the instance id from instances.
Select the resource type -> instance and instance ID
Click on Create snapshot
Snapshot is ready and now you can perform your task on the running servers.
Suppose something goes wrong, now I need to restore the server using these snapshots. The apache server was running on this server as shown in the below figure.
Now terminate the instance.
Click on yes terminate
Restore EC2 from Elastic block store
EC2 -> Elastic block store -> snapshots -> actions -> create image
Fill the details
Click on create
You can see the images under images -> AMI
Now simply launch the server using this AMI and check everything will be the same as before. When you will launch the server using this AMI.
Now access the server and see apache should be there.
