About this Hands-on Lab

This hands-on lab will help to provide experience working with snapshots on Compute Engine, both in the web console and command line format, which we will interact with via Cloud Shell.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create snapshot using web console.
  1. Go to the top-left menu > Compute Engine > Snapshots
  2. Click Create snapshot
  3. Name snapshot "web-backup-v1"
  4. In Source Disk dropdown menu, select Website
  5. Click Create
Make instance change – update website to VERSION 2.
  1. Connect to the website instance using SSH from the Compute Engine web console

  2. Enter the following command to replace index page with ‘VERSION 2’ instead of ‘VERSION 1’:

    sudo sed -i 's/VERSION 1/VERSION 2/' /var/www/html/index.html
  3. Exit SSH session

Create new snapshot using the Cloud Shell
  1. Open Cloud Shell and enter following command:

    gcloud compute disks snapshot website --snapshot-names web-backup-v2 --zone us-central1-a
  2. Verify snapshots using web console and Cloud Shell. Notice the size of the second snapshot compared to first:

    gcloud compute snapshots list
    gcloud compute snapshots describe web-backup-v2
Restore first snapshot using web console in new zone.
  1. Go to top left menu > Compute Engine
  3. Name instance "website-restore-1"
  4. Choose a region/zone
  5. Change boot disk:
    • Select Snapshots
    • Select web-backup-v1
    • Click Select at the bottom
  6. Select box to allow HTTP traffic
  7. Click Create
Restore second snapshot using command line
  1. Navigate to Cloud Shell

  2. Create disk from snapshot:

    gcloud compute disks create website-restore-2 --source-snapshot web-backup-v2 --zone us-central1-a
  3. Create new instance from disk:

    gcloud compute instances create website-restore-2 --disk name=website-restore-2,boot=yes --zone us-central1-a --tags=http-server


Congratulations, you’ve completed this hands-on lab!
