          Creating a snapshot explains 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.

          Note

          Additional fees apply when you use the snapshot function. For more information about the pricing plan, see in the Pricing information 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.
          The following describes how to create a snapshot.

          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. Click the environment you are using in the Region menu and Platform menu of NAVER Cloud Platform console.
          2. Click the Services > Compute > Server menus, in that order.
          3. Click the Storage menu.
          4. On the storage list, click to select the storage you want to create a snapshot of, and then click [Set storage] > Create snapshot, in that order.
          5. Enter the snapshot name in the Create snapshot pop-up window, and then 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 then click the [Create] button.
          7. Check the details in the pop-up window, and then 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

          The following describes how to create a full storage snapshot of a storage.

          1. Click the environment you are using in the Region menu and Platform menu of NAVER Cloud Platform console.
          2. Click the Services > Compute > Server menus, in that order.
          3. Click the Storage menu.
          4. On the storage list, click to select the storage you want to create a snapshot of, and then click [Set storage] > Create snapshot, in that order.
          5. In the Create snapshot pop-up window, select Full storage snapshot as the snapshot type.
          6. 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 (_).
          7. Check the information of the snapshot to be created, and then click the [Create] button.
          8. Check the details in the pop-up window, and then click the [OK] button.
            • A snapshot is created. You can check the created snapshot in the Snapshot menu.

          Create incremental snapshot

          The following describes how to create an incremental snapshot of a storage.

          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 04, 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. Click the environment you are using in the Region menu and Platform menu of NAVER Cloud Platform console.
          2. Click the Services > Compute > Server menus, in that order.
          3. Click the Storage menu.
          4. On the storage list, click to select the storage you want to create a snapshot of, and then click [Set storage] > Create snapshot, in that order.
          5. In the Create snapshot pop-up window, select Incremental storage snapshot as the snapshot type.
          6. 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 (_).
          7. Check the information of the snapshot to be created, and then click the [Create] button.
          8. Check the details in the pop-up window, and then click the [OK] button.
            • A snapshot is created. You can check the created snapshot in the Snapshot menu.

          Check snapshot information

          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, then the snapshot list isn't displayed on the Snapshot page.

          The following describes how to check the snapshot details.

          1. Click the environment you are using in the Region menu and Platform menu of NAVER Cloud Platform console.
          2. Click the Services > Compute > Server menus, in that order.
          3. Click the Snapshot menu.
          4. When the list of snapshots appears, view the summary information or click a snapshot to check the details.
