Recovering a disk from a snapshot

Written by
Updated at October 17, 2024

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 a snapshot:

  1. In the management console, select the folder where you want to create a disk.

  2. Select Compute Cloud.

  3. In the left-hand panel, select Disks.

  4. Click Create disk.

  5. Enter a name for the disk. The naming requirements are as follows:

    • 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.

  6. Provide a description for the disk, if required.

  7. Select the availability zone the disk will be in.

  8. Set the disk parameters: disk type, block size, and disk size.

  9. In the Contents field, select Snapshot and then select the snapshot you need from the list below. Use the filter to find the snapshot.

  10. 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.

  11. 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.

  1. View the description of the CLI commands for managing disks and their snapshots:

    yc compute disk create --help
yc compute snapshot --help

  2. Get a list of snapshots in the default folder:

    yc compute snapshot list

    Result:

    +----------------------+----------------------+----------------------+----------+
|          ID          |         NAME         |     PRODUCT IDS      |  STATUS  |
+----------------------+----------------------+----------------------+----------+
| fd84hanhvjql******** | disk-1-1668075122980 | f2ef3frbftr2******** | READY    |
| fd85mc22cosp******** | disk-2-1669114692462 | f2ef3frbftr2******** | READY    |
+----------------------+----------------------+----------------------+----------+

  3. Select ID or NAME of the snapshot you need.

  4. Create a disk from the selected snapshot.

    yc compute disk create <disk_name> \
  --source-snapshot-name <snapshot_name> \
  --description <text_description_of_disk>

    You can use the --source-snapshot-name or --source-snapshot-id parameter to specify the snapshot.

    For more information about the yc compute disk create command, see the CLI reference.

  5. Get a list of disks in the default folder:

    yc compute disk list

    Result:

    +----------------------+--------------+-------------+-------------------+--------+----------------------+-----------------+-------------+
|          ID          |     NAME     |    SIZE     |       ZONE        | STATUS |     INSTANCE IDS     | PLACEMENT GROUP | DESCRIPTION |
+----------------------+--------------+-------------+-------------------+--------+----------------------+-----------------+-------------+
| a7lqgbt0bb9s******** | first-disk   | 20401094656 |   ru-central1-a   | READY  | a7lcvu28njbh******** |                 |             |
| a7lv5j5hm1p1******** | second-disk  | 21474836480 |   ru-central1-a   | READY  |                      |                 |             |
+----------------------+--------------+-------------+-------------------+--------+----------------------+-----------------+-------------+

    Get the same list with more details in YAML format:

    yc compute disk list --format yaml

    Result:

    - id: fhm4aq4hvq5g********
    folder_id: b1gm3og7ei7a********
    created_at: "2018-10-29T07:43:06Z"

  1. Get a list of snapshots using the SnapshotService/List gRPC API call or the list REST API method for the Snapshot resource.
  2. Create a disk using the DiskService/Create gRPC API call or the create REST API method for the Disk resource. Specify the snapshot ID in your request.

Once created, the disk will get the CREATING status. Wait until the disk status changes to READY before using it.
