EC2 instance /etc folder deleted , couldnt connect now AMI- ami-04b4f1a9cf54c11d0

Try this:

1. Stop the Instance and Create a Backup

• Stop the Instance: Go to the AWS Management Console, navigate to the EC2 dashboard, and stop the affected instance.

• Create a Snapshot: Take a snapshot of the root volume to ensure you have a backup before making any changes.

2. Detach and Attach the Root Volume

• Detach the Root Volume:

• In the EC2 dashboard, select the instance and detach the root volume.

• Attach the Volume to Another Instance:

• Attach the root volume to a temporary EC2 instance as a secondary volume.

3. Repair the /etc Folder

• Mount the Volume:

• SSH into the temporary instance.

• Mount the attached volume (e.g., /dev/xvdf) to a directory:

sudo mkdir /mnt/temp
sudo mount /dev/xvdf1 /mnt/temp

• Restore the /etc Folder:

Copy the /etc folder from the temporary instance to the mounted volume:

sudo cp -r /etc /mnt/temp/

• Ensure permissions are correct:

sudo chmod -R 755 /mnt/temp/etc

4. Reattach the Volume

• Detach the repaired volume from the temporary instance.

• Reattach it as the root volume to the original instance.

5. Start the Original Instance

• Start the original instance and check if it boots correctly.

• Test SSH access to ensure the issue is resolved.

6. Prevent Future Issues

• Regularly back up critical system files using snapshots or AMIs.

• Use IAM roles and policies to restrict access to sensitive directories.
