Available in VPC
In Backup, you can check the backup information configured per server for safe storage of cache data for users using Cloud DB for MSSQL. Also, when the cache data is damaged due to a failure, you can perform restoration using the backup file that was in storage. In addition to servers using high availability settings, you can also use the backup and restoration features for Stand Alone Server.
To use the backup and restoration, it is recommended to first understand the basic execution rules for the backup provided by Cloud DB for MSSQL. The basic backup execution rules are as follows:
- Backup execution methods
- Full backup: Performed daily, once a day
- Select between automatic settings and user-defined settings
- Automatic settings: A random time will be specified when an MSSQL server is created, and the backup will be performed at a time similar to the time of the first backup
- User-defined settings: Backups are performed within 15 minutes from the time selected by the user.
- Log backup: Performed automatically at 15-minute intervals. Backup time can't be specified
- Backup file
- Retention period: Can be stored for up to 30 days according to the user settings.
- Storage location: A separate data storage (storage contracts are made according to the backup file size.)

Check backup file list per server
To view the backup file list created for each server after completing the backup:
- In the VPC environment of the NAVER Cloud Platform console, navigate to Menu > Services > Database > Cloud DB for MSSQL.
- Click the Backup menu.
- Click [Details] from View details of the backup settings row you want to check the details for.
- Check the details for the backup file.

Restoration
Cloud DB for MSSQL provides a service that enables you to restore lost data using backup files and easily and quickly create an MSSQL Server. You can select the backup file you want to restore from the list of backup files in storage and restore the MSSQL server. To restore:
- The backup file stores the data from the time of backup completion. Thus, when you restore it, it is restored to the data from the time of backup completion.
- You can restore up to the desired minute within the range available for restoration. Due to the characteristics of MSSQL, the most recent point in time available for restoration is 20 minutes prior to the current time.
- When you restore it, it is restored to the server specifications that were stored in the backup file. If you want to upgrade the server specifications after restoration, use the Change DB specifications feature from the DB Server menu.
- In the VPC environment of the NAVER Cloud Platform console, navigate to Menu > Services > Database > Cloud DB for MSSQL.
- Click the Backup menu.
- Click [Details] under View details of the backup settings row you want to restore.
- Click [Restore].
- When the DB Restore popup window appears, check the specifications of the server to be newly created and time available for recovery through backup.

- Select a subnet to use in the DB server to be restored.
- Select a DB server type to be restored.
- Select a storage type for saving DB data.
- Enter the name of the DB service to be newly created.
- Enter between 3 and 15 characters using Korean letters, English letters, numbers, and hyphens (-).
- Duplicate names are not allowed.
- Set the date and time of recovery within the range of time available for recovery you checked from Step 5.
- Click [OK] to check the information of the database to be recovered.
- DB name: Database name to be used for restoration
- Recovery model: A database model type to be used for restoration
- Full backup size: Size of full backup files to be used for restoration (MB)
- Log backup size: Size of log backup files to be used for restoration (MB)
- Number of log backup: Number of log files to be used for restoration. A log file is created every 15 minutes
- DB recovery point: The time when the database is restored and reverted
- Click [v Recovery].
- Check the status of the server being restored from the MSSQL server list on the DB server page.
- Creating: Status in which the MSSQL server is being created (restored) with the information entered by the user
- Configuring: Status in which the MSSQL server is being configured after being created (restored) with the information entered by the user
- Running: Status in which the creation (restoration) and configuration of the MSSQL server has been completed with the information entered by user, and access to the MSSQL server from the application servers is available
The completion of the server restoration may take a certain amount of time (minutes).
Delete backup file
To delete backup files created for each MSSQL server:
- Deleting backup files may impact recovery so that recovery to a certain point may not be available.
- Backup files can't be recovered once deleted.
- It is not possible to delete the Master DB.
- In the VPC environment of the NAVER Cloud Platform console, navigate to Menu > Services > Database > Cloud DB for MSSQL.
- Click the Backup menu.
- Click [Details] from View details of the backup settings row you want to delete backup files.
- Select a backup file to delete. You can select multiple backup files.
- Click [Delete].
- When the Delete MSSQL backup file popup window appears, check the information of the backup file to delete.

- Click [Yes].
Send to Object Storage
Cloud DB for MSSQL allows you to store the backup files you create in Object Storage. To save a stored backup file to Object Storage:
- In the VPC environment of the NAVER Cloud Platform console, navigate to Menu > Services > Database > Cloud DB for MSSQL.
- Click the Backup menu.
- Select the backup file and click [Send to Object Storage].

- When the Send to Object Storage popup window appears, click and select the bucket and folder you want to save into.

- Click [Send to Object Storage].
- Click [OK].
You can also save transaction log backup files to Object Storage by clicking View Log Backup > Log Backup.
- Additional fees apply when you subscribe to Object Storage. For more information about Object Storage and its pricing plans, see Services > Storage > Object Storage on the NAVER Cloud Platform portal.
- When sending files to Object Storage, you must unlock buckets, control appropriate access, and set up ACLs.
- For the Japan Region, disable access control settings for the Object Storage bucket.
- It may take several minutes for the file transfer to complete.
