Create New Snapshot Using the Cloud Shell
1. Activate the Cloud Shell by clicking its icon in the top row.
2. If no ID is displayed in yellow in the Cloud Shell, open the Project panel by clicking the project name in the upper-left.
3. Copy the current project ID.
4. In the Cloud Shell, enter the following command:
```
gcloud config set project <PROJECT_ID>
```
5. Create a new snapshot with the following command:
```
 gcloud compute disks snapshot website --snapshot-names web-backup-v2 --zone us-central1-a
```
6. 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
```
Challenge
