Recovering a disk from an image
Note
You cannot recover a boot disk of an existing VM from a snapshot or image. However, you can create a new VM to recover a boot disk from a snapshot. To recover a boot disk on an existing VM, use Yandex Cloud Backup.
To create a disk from an image:
-
In the management console
, select the folder where you want to create a disk. -
Select Compute Cloud.
-
In the left-hand panel, select
Disks. -
Click Create disk.
-
Enter a name for the disk.
- The name must be from 3 to 63 characters long.
- It may contain lowercase Latin letters, numbers, and hyphens.
- The first character must be a letter and the last character cannot be a hyphen.
-
Provide a description for the disk, if required.
-
Select the availability zone the disk will be in.
-
Set the disk parameters: disk type, block size, and disk size.
-
In the Contents field, select
Image
and select the image you need in the list below. Use the filter to find the image. -
(Optional) To encrypt a disk, under Disks and file storages, configure encryption parameters for the disk:
- Select the Encrypted disk option.
- In the KMS Key field, select the key with which you want to encrypt the disk. To create a new key, click Create.
The encryption feature in Compute Cloud is currently at the Preview stage. To access it, open the resource creation page and click Request access under Encryption or contact support
.If you deactivate the key used to encrypt a disk or snapshot, access to the data will be suspended until you reactivate the key.
Alert
If you destroy the key or its version used to encrypt a disk or snapshot, access to the data will be irrevocably lost. Learn more in Destroying key versions.
-
If required, select a schedule for automatic snapshot creation, or set up a new schedule. For more information about setting up schedules, see this guide.
You can create snapshots of network drives, such as HDDs, SSDs, and non-replicated SSDs, as well as ultra-high performance network storages with three replicas (SSD).
For non-replicated SSDs and ultra-high performance network storages with three replicas (SSD), the snapshot time is not determined.
To take snapshots of local disks residing on dedicated hosts, use Yandex Cloud Backup. This service supports Ubuntu, CentOS, CentOS Stream, and Windows Server.
When creating a disk, you can select only one snapshot schedule. Once the disk is created, you can add a few more schedules by following the instructions.
-
Click Create disk.
If you do not have the Yandex Cloud command line interface yet, install and initialize it.
The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name
or --folder-id
parameter.

You can use either
--source-image-name
or--source-image-id
to specify the image.For more information about the

- Get a list of images using the ImageService/List gRPC API call or the list REST API method for the
Image
resource. - Create a disk using the DiskService/Create gRPC API call or the create REST API method for the
Disk
resource. Specify the image ID in your request.
Once created, the disk will get the CREATING
status. Wait until the disk status changes to READY
before using it.
