After checking the set information, click the **[OK]** button. - Storage is created. You can check the created storage from the **Storage** menu. ### 2. Set server (Linux) To add the storage created by the snapshot to the Linux server, proceed with the following steps in order: [1. Check storage identifier and file system type](/docs/en/server-snapshot-classic#1%EC%8A%A4%ED%86%A0%EB%A6%AC%EC%A7%80%EC%8B%9D%EB%B3%84%EC%9E%90%EB%B0%8F%ED%8C%8C%EC%9D%BC%EC%8B%9C%EC%8A%A4%ED%85%9C%ED%83%80%EC%9E%85%ED%99%95%EC%9D%B8) [2. Change storage identifier](/docs/en/server-snapshot-classic#2%EC%8A%A4%ED%86%A0%EB%A6%AC%EC%A7%80%EC%8B%9D%EB%B3%84%EC%9E%90%EB%B3%80%EA%B2%BD) [3. Mount storage](/docs/en/server-snapshot-classic#3%EC%8A%A4%ED%86%A0%EB%A6%AC%EC%A7%80%EB%A7%88%EC%9A%B4%ED%8A%B8) #### 1. Check storage identifier and file system type Check storage identifier and file system type. 1. Access the Linux server to which storage is connected. - For more information on how to connect to the server, see [Access Linux server](/docs/en/server-access-classic#Linux%EC%84%9C%EB%B2%84%EC%A0%91%EC%86%8D). 2. Check the storage identifier and file system type created by snapshot through the `blkid` command. - The storage identifier is displayed as the `UUID` value. - The file system type is displayed as the `TYPE` value. . 3. According to the result of Step 2, proceed with the following steps: - If you have duplicated storage identifiers, proceed with [3. Change storage identifier](/docs/en/server-snapshot-classic#3%EC%8A%A4%ED%86%A0%EB%A6%AC%EC%A7%80%EC%8B%9D%EB%B3%84%EC%9E%90%EB%B3%80%EA%B2%BD). - If the identifiers of each storage are all different, proceed with [4. Mount storage](/docs/en/server-snapshot-classic#4%EC%8A%A4%ED%86%A0%EB%A6%AC%EC%A7%80%EB%A7%88%EC%9A%B4%ED%8A%B8). #### 2. Change storage identifier In the following case, if the identifier of the storage in the original server is the same as the identifier of the created storage, the storage cannot be mounted. - Creating a snapshot in one of the existing storages of the server to which storages were added - Creating a snapshot from the basic boot storage of another server If applicable, you need to first change the identifier of the created storage. Proceed with the operation according to the file system type checked in [1. Check storage identifier and file system type](/docs/en/server-snapshot-classic#1%EC%8A%A4%ED%86%A0%EB%A6%AC%EC%A7%80%EC%8B%9D%EB%B3%84%EC%9E%90%EB%B0%8F%ED%8C%8C%EC%9D%BC%EC%8B%9C%EC%8A%A4%ED%85%9C%ED%83%80%EC%9E%85%ED%99%95%EC%9D%B8). - [xfs file system type](/docs/en/server-snapshot-classic#xfs%ED%8C%8C%EC%9D%BC%EC%8B%9C%EC%8A%A4%ED%85%9C%ED%83%80%EC%9E%85) - [ext4 file system type](/docs/en/server-snapshot-classic#ext4%ED%8C%8C%EC%9D%BC%EC%8B%9C%EC%8A%A4%ED%85%9C%ED%83%80%EC%9E%85) **xfs file system type** The following describes how to change the identifier of a storage using the `xfs` file system. The description is based on the `xvdb1` storage. Caution Since `/dev/xvda` is the device file name of the basic boot storage, do not change this identifier. If you change the identifier of the basic boot storage, the server may not be able to boot. 1. Enter the `xfs_repair -L /dev/xvdb1` command. - The storage identifier of `xvdb1` is deleted. 2. Enter the `xfs_admin -U generate /dev/xvdb1` command. - A new identifier is created for the `xvdb1` storage. 3. Check if it is changed into a new identifier by the `blkid` command. **ext4 file system type** The following describes how to change the identifier of a storage using the `ext4` file system. The description is based on the `xvdb1` storage. Caution Since `/dev/xvda` is the device file name of the basic boot storage, do not change this identifier. If you change the identifier of the basic boot storage, the server may not be able to boot. 1. Enter the `tune2fs -U "UUID" /dev/xvdb1` or `tune2fs -U random /dev/xvdb1` command. - Enter the desired storage identifier into the "UUID" location and run it. - The random option sets the UUID as a random value. Note You can create a new UUID by entering the `uuidgen` command. 1. Check if it is changed into a new identifier by the `blkid` command. The following errors may occur if the UUID is changed with the `tune2fs` command after creating and allocating snapshot and storage while operating the server for the basic boot storage of the `ext4` file system type. Note For the booting disk, create the snapshot when the server is stopped to prevent data loss issues. ``` # tune2fs /dev/xvdb1 -U random This operation requires a freshly checked filesystem. Please run e2fsck -f on the filesystem. ``` Perform the following procedures in the relevant cases. ``` # file -s /dev/xvdb1 ``` Check if the phrase "needs journal recovery" is output in the command execution result value. If the phrase is output, it means that the file system is damaged. Conduct the file system inspection and recovery with the following commands: ``` # e2fsck -f /dev/xvdb1 -y ``` ``` # tune2fs /dev/xvdb1 -U random ``` 1. Check storage device status 1. Conduct the file system inspection and recovery 1. Conduct the storage identifier change task #### 3. Mount storage See [Mount storage](/docs/en/server-storage-classic#%EC%8A%A4%ED%86%A0%EB%A6%AC%EC%A7%80%EB%A7%88%EC%9A%B4%ED%8A%B8Linux) to mount the created storage. Note Since the storage data is read and recovered from the snapshot, skip the disk partition and storage format tasks. ### 2. Set server (Windows) To add the storage created by the snapshot to the Windows server, set the storage status to online. The following describes how to set the storage status online on the Windows server. 1. Access the Windows server to which storage is connected. - For more information on how to connect to the server, see [Access Windows server](/docs/en/server-access-classic#Windows%EC%84%9C%EB%B2%84%EC%A0%91%EC%86%8D). 2. Click ![i-server_window_start](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/i-server_window_start.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A16%3A23Z&se=2026-11-14T06%3A16%3A23Z&sr=c&sp=r&sig=cihkq8vONanObUOxGut%2B9pxCw5eVLQstGFQW8XSufgM%3D) and then click the **Windows Administrative Tools > Computer Management > Disk Management** menus, in that order. - Alternatively, you can enter `diskmgmt.msc` on the Run command window. 3. Find the disk marked with **Offline** from the disk list, right-click the button, and then click **Online**. - You can now use the storage. Note Since the storage data is read and recovered from the snapshot, skip the disk partition and storage format tasks. ## Replicate snapshot The following describes how to replicate the created snapshot to another Region: 1. In the Classic environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Compute** > **Server**. 2. Click the **Snapshot** menu. 3. From the snapshot list, click to select the snapshot to replicate, and then click the **[Replicate to another Region]** button. 4. From the Replicate to another Region pop-up window, select the Region you want to replicate the snapshot to, enter the snapshot name, and then click the **[Create]** button. 5. Check the details in the pop-up window, and then click the **[OK]** button. - It may take several minutes to several hours to replicate a snapshot depending on the size of the snapshot you want to replicate. - You can't cancel replication and can't delete the snapshot that is being replicated until the replication is completed. ## Delete snapshot The following describes how to delete the created snapshot. Caution Deleted snapshot data can't be recovered. Make sure to review carefully before deleting. 1. In the Classic environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Compute** > **Server**. 2. Click the **Snapshot** menu. 3. Click to select the snapshot to delete from the snapshot list, and then click the **[Delete snapshot]** button. 4.
