Create and manage instant snapshots | Compute Engine Documentation

This document explains how to create and manage instant snapshots. Instant snapshots capture the contents of a disk and can be used to create a new disk in minutes.

Instant snapshots are stored in the same zone or region as their source disks and are not a replacement for standard snapshots, which offer off-site backup for disaster recovery. Learn about the other data protection options available in Compute Engine.

To access the data on an instant snapshot, use the instant snapshot to create a new disk.

If you want to copy an instant snapshot to another location or retain the snapshotted data after the source disk is deleted, create a standard snapshot from the instant snapshot.

Before you begin

If you haven't already, then set up authentication. Authentication is the process by which your identity is verified for access to Google Cloud services and APIs. To run code or samples from a local development environment, you can authenticate to Compute Engine by selecting one of the following options:
Select the tab for how you plan to use the samples on this page:
Console
When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.
gcloud
1. Install the Google Cloud CLI. After installation, initialize the Google Cloud CLI by running the following command:
```
gcloud init
```
  If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.
  Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.
2. Set a default region and zone.
REST
To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.
For more information, see Authenticate for using REST in the Google Cloud authentication documentation.

Required roles and permissions

To get the permissions that you need to create instant snapshots, ask your administrator to grant you the following IAM roles on the project:

Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1)
To connect to a VM that can run as a service account: Service Account User (v1) (roles/iam.serviceAccountUser)

For more information about granting roles, see Manage access to projects, folders, and organizations.

These predefined roles contain the permissions required to create instant snapshots. To see the exact permissions that are required, expand the Required permissions section:

Required permissions

The following permissions are required to create instant snapshots:

To create an instant snapshot: compute.instantSnapshots.create
To view instant snapshots: compute.instantSnapshots.list
To view instant snapshots details: compute.instantSnapshots.get
To delete an instant snapshot: compute.instantSnapshots.delete

You might also be able to get these permissions with custom roles or other predefined roles.

Limitations

You can't create instant snapshots of Hyperdisk Throughput or Hyperdisk ML volumes.
You can't select the storage location of an instant snapshot. It's always stored in the same region or zone as the source disk.
When you delete a disk, all instant snapshots of the disk are deleted. This means that when you delete a VM, instant snapshots of the VM's boot disk are deleted. Instant snapshots of non-boot disks attached to the VM are also deleted if you've enabled auto-delete for the disk. To retain the data on an instant snapshot before it is deleted, create a standard snapshot from the instant snapshot.
An instant snapshot is accessible only within the zone or region where it's stored. To move an instant snapshot to another region, you must create a standard snapshot from the instant snapshot.
When you create a disk from a CMEK-encrypted instant snapshot, you must provide the instant snapshot's encryption key.
You can create a standard snapshot of an individual disk at most 6 times every 60 minutes. This limit also applies to creating a standard snapshot from an instant snapshot of a disk.
You can't create a VM from an instant snapshot of a boot disk. Create a disk from the instant snapshot first, and choose the disk as the source for the VM.
You can create an instant snapshot of a given disk at most once every 30 seconds.
You can't have more than 32 instant snapshots of the same disk.
You can't create instant snapshots with snapshot schedules.
You can't create instant snapshots on secondary asynchronously replicated Persistent Disk volumes.
Instant snapshots are crash consistent and not application consistent. This means that any in-memory data that hasn't yet been written to the disk isn't captured in the instant snapshot. If you require application consistency, create an application consistent standard snapshot.
You can't move a disk until you delete all the instant snapshots of the disk. For more information, see Moving a disk that has instant snapshots.
You can't edit the data stored in an instant snapshot.
You can't recover deleted instant snapshots.

Create an instant snapshot of a disk

Instant snapshots of zonal disks are stored in the same zone as the source disk. Likewise, instant snapshots of regional disks are stored in the same region as the disk.

You can create an instant snapshot with the gcloud CLI, Google Cloud console, or REST.

Console

In the Google Cloud console, go to the VM instances page.

Go to VM instances
Select the project you want to work with.
In the Name column, click the name of the VM attached to the disk you want to back up.
In the Storage section, select a disk in one of the following ways:
- To back up the VM's boot disk, in the Boot disk section, click the Name of the boot disk.
- To back up an attached disk volume, in the Additional disks section, click the Name of the disk.
To finish creating an instant snapshot, on the Create a snapshot page, do the following:
1. In the Name field, enter a unique name to identify the instant snapshot.
2. Optional: Add more details about the snapshot in the Description field.
3. In the Type field, select Instant snapshot. The Location field is automatically set to the same zone or region as the disk.
4. In the Snapshot source type field, verify that Disk is selected.
5. Optional: To organize your project, add one or more labels.
6. Click Create.

gcloud

To create an instant snapshot, use the gcloud compute instant-snapshots create command:
