Create snapshot

Prev Next

Available in VPC

The following describes how to create snapshots for different hypervisors.

If you create a snapshot, you can store data in storage and create new storage on the desired server with the generated snapshot to restore the stored data.

Caution

Additional fees apply when you use the snapshot feature. The billing unit for the storage capacity (GB) when creating snapshots are as follows:

  • HDD/SSD (XEN-based)
    • Full storage snapshots are billed based on the total storage volume size (total capacity).
    • Incremental snapshots are billed based on the actual usage within the storage volume (the changes in the full snapshot).
  • CB1/FB1 (KVM-based)
    • Billed based on the storage volume size (total capacity).
    • All snapshots are billed based on the total storage volume size (total capacity), regardless of the snapshot order.
  • CB2/FB2 (KVM-based)
    • The first snapshot is billed based on the storage volume size (total capacity).
    • Subsequent snapshots are billed based on the actual usage (actual size) within the storage volume.
      • To check actual usage: see snapshot list > click on snapshot > snapshot details > size > the capacity shown in parentheses.
    • Deleting a snapshot may change the actual size of other snapshots from the same original storage, and the snapshot billing capacity may also be changed. See Delete snapshot.
      For more information on snapshot pricing, see Pricing information on the portal.

Create snapshot

You can create full storage snapshots and incremental snapshots. Full storage snapshot saves the entire data of the storage based on the creation time. Incremental snapshots only save the changed data of the storage after creating the full storage snapshot.

Create KVM-based snapshot

If hypervisor is KVM-based, you can create snapshots using Block Storage.
To create a snapshot, follow these steps:

Note
  • Synchronize the file system by executing the sync command before you create a snapshot.
  • Until the snapshot creation is complete, you can't delete the original storage.
  • If the original storage size is too large or if numerous snapshots were created from that storage, creating a new snapshot may take a long time.
  • When creating a snapshot, it may take longer than 4 hours for storage 1T.
  • If there are over 50 snapshots created from one storage, it could severely increase the time to create a snapshot.
  • If you create a snapshot after HA has occurred in the original storage that is connected with the original server of the snapshot, it may take longer than previous times to create a snapshot.
  1. In the VPC environment of the NAVER Cloud Platform console, navigate to i_menu > Services > Compute > Server.
  2. Click the Storage menu.
  3. On the storage list, click to select the storage you want to create a snapshot of, and click [Set storage] > Create snapshot in order.
  4. Enter the snapshot name in the Create snapshot popup window, and click the [Next] button.
    • Snapshot names must start with an English letter and you must enter between 3-30 characters using English, numbers, hyphens (-), and underscores (_).
  5. Check the information of the snapshot to be created, and click the [Create] button.
  6. Check the details in the popup window and click the [OK] button.
    • A snapshot is created. You can check the created snapshot in the Snapshot menu.

Create XEN-based snapshot

If the hypervisor is XEN-based, you can create either full storage snapshots or incremental snapshots.

Create full storage snapshot

To create a full storage snapshot of a storage, follow these steps:

  1. In the VPC environment of the NAVER Cloud Platform console, navigate to i_menu > Services > Compute > Server.
  2. Click the Storage menu.
  3. On the storage list, click to select the storage you want to create a snapshot of, and click [Set storage] > Create snapshot in order.
  4. In the Create snapshot popup window, select Full storage snapshot as the snapshot type.
  5. Enter the snapshot name and click the [Next] button.
    • Snapshot names must start with an English letter and you must enter between 3-30 characters using uppercase and lowercase English letters, numbers, hyphens (-), and underscores (_).
  6. Check the information of the snapshot to be created, and click the [Create] button.
  7. Check the details in the popup window and click the [OK] button.
    • A snapshot is created. You can check the created snapshot in the Snapshot menu.

Create incremental snapshot

To create an incremental snapshot of a storage, follow these steps:

Note
  • You can create incremental snapshots only when a full storage snapshot of the storage exists.
  • The incremental snapshot is created based on the latest full storage snapshot of the storage.
  • You can create up to 7 incremental snapshots. If you need more data changes than this, you need to create a new full storage snapshot.
  • The creation of incremental snapshot is not available for following cases:
    • If you're trying to create an incremental snapshot with a full storage snapshot made before March 4, 2021
    • If the storage you're trying to create the incremental snapshot of is removed from the server or removed and then reconnected
    • If the storage capacity has changed
    • If other incremental snapshots created earlier are deleted
  1. In the VPC environment of the NAVER Cloud Platform console, navigate to i_menu > Services > Compute > Server.
  2. Click the Storage menu.
  3. On the storage list, click to select the storage you want to create a snapshot of, and click [Set storage] > Create snapshot in order.
  4. In the Create snapshot popup window, select Incremental storage snapshot as the snapshot type.
  5. Enter the snapshot name and click the [Next] button.
    • Snapshot names must start with an English letter and you must enter between 3-30 characters using English, numbers, hyphens (-), and underscores (_).
  6. Check the information of the snapshot to be created, and click the [Create] button.
  7. Check the details in the popup window and click the [OK] button.
    • A snapshot is created. You can check the created snapshot in the Snapshot menu.

Check snapshot details

You can find the detailed information of the created snapshots in the snapshot list.

Note

You can see the snapshot list only when 1 or more snapshots are created. If there is no created snapshot, the snapshot list isn't displayed on the Snapshot page.

To check the snapshot details, follow these steps:

  1. In the VPC environment of the NAVER Cloud Platform console, navigate to i_menu > Services > Compute > Server.
  2. Click the Snapshot menu.
  3. When the list of snapshots appears, view the summary information or click a snapshot to check the details.

    • Snapshot name (Instance ID): snapshot name you entered when creating a server and the automatically assigned unique ID

    • Hypervisor: hypervisor type of the original storage

    • Original storage name: name of the original storage from which the snapshot was created

    • Default storage status (KVM only): whether it is the default storage included in the OS

    • Snapshot type (XEN only): whether it is a full or incremental snapshot

    • Depth (n) (XEN only): depth number of the snapshot

    • Size: capacity of the snapshot provided in GB

      Note

      The snapshot size for g3 servers refers to the allocated logical capacity (virtual size). If a value is displayed in parentheses, it indicates the actual usage (actual size). Deleting a snapshot may change the actual size of other snapshots from the same source storage.

    • Status/progress status: current status of the snapshot

      • Creating: status in which the snapshot is being created with the information you entered
      • Created: status in which the snapshot is available for normal use
      • Returning: status in which the snapshot is being deleted
      • Replicating: status in which the current server is being replicated by running Create storage with snapshot

    • Creation date and time: date and time when the snapshot was created

    • Apply encryption to storage: whether to apply encryption to the storage to be created from snapshots
