Backup

Available in Classic and VPC

You can migrate data using NAVER Cloud Platform's Backup.

Data migration using Backup

To migrate data between servers using Backup, conduct the following steps in order:

• Create resources and install the agent
• Create storage and storage policy
• Backup job and schedule
• Restore backup version

Create resources and install the agent

You must first create a resource to use the backup service.
This is a process of selecting a server for backup and creating it as a backup resource. The following describes how to create a resource.

1. Click the environment you are using in the Region menu and Platform menu of NAVER Cloud Platform console.

2. Click the Services > Storage > Backup menus, in that order.

3. Click the Backup > Resource menus, in that order.

4. If you don't have any resources, click the [Create resource] button.

5. Consent to the Terms and Conditions of collection and use of personal information, and then click the [OK] button.

6. Enter the resource name.

   • Enter between 3-30 characters in a combination of English lowercase letters, numbers, and hyphens.

7. Select a zone.

8. Select the server for backup.

   • Select the backup server from VM and BM.

9. Set the host name.

   Note

   • If using the Windows server, the backup agent is normally installed only when the name is the same as the host name. If you don't enter anything, the same name as the server is entered.
   • If using the Windows server, you need to set the WMI Port. See Fix WMI Port to set it.

10. Select the agent type for installation.

    • You can select between Data and DB, or both.
    • Data: performs backup for all data areas except the OS area
    • DB: performs backup for the DB area installed on the VM (supported DB: MSSQL, MySQL, and PostgreSQL)
      • If the server is a Linux OS, mssql agent cannot be installed

11. Enter the ID and password.

    • It's a one-off login information for accessing the resource server while installing the agent. The one-off login information is not saved.
    • ID: enter 256 characters or less by combining English characters, numbers, hyphens, and underscores.
      • Account requirements for the use of DB agent
        • SSQL Server User: must belong to the administrators group and have sysadmin permissions (Windows authentication method)
        • MySQL Server User: NT/ Linux users with OS admin permissions and users with SA permissions
        • PostgreSQL Server User: postgres users with admin permissions
    • If using Linux
      • You must install the agent with the root account.
      • If the root account is unavailable, you configure the following for the account for installing the backup agent. After installation of the backup agent is completed, delete the granted root permissions.

        Account to be used for agent installation: test01 
        [root@backup-linux01 ~]# vi /etc/sudoers 
        ## Allow root to run any commands anywhere 
        root    ALL=(ALL)       ALL 
        test01  ALL=NOPASSWD:   ALL
        

    • If using Windows
      • You must use the administrator account.
      • If you cannot use the administrator account, you must grant the administrator permissions to the account to be used for installation of the agent. After installation of the backup agent is completed, delete the granted administrator permissions.

12. Click the [Next] button.

13. After the final check of information for creating the resource, click the [Create resource] button.

    • If you've installed a DB-type agent, click the [Add DB instance] button after creating the resource to enter DB information additionally.
