Backup

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 MongoDB. Also, when the cache data is damaged due to a failure, you can perform restoration using the backup file that was in storage. To use the backup and restoration, it is recommended to first understand the basic execution rules for the backup provided by Cloud DB for MongoDB. The basic backup execution rules are as follows:

• Backup execution methods

  • Performed daily, once a day
  • Backups are performed within 15 minutes from the time selected by the user
    • Exceptional situations
      • If the backup from the previous day is still being performed due to a large backup size, the backup schedule for that day is skipped
      • Since the admin Database includes system collection and internal logic, it is excluded from backup
        • You must avoid storing user data in the admin Database

• Backup file

  • Retention period: can be stored 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)

The basics of using the backup are as follows:

Check backup settings list

You can check the backup settings list per MongoDB server in operation. The following describes how to check the backup settings list.

1. Click the Services > Database > Cloud DB for MongoDB menus from the VPC environment of NAVER Cloud Platform console, in that order.
2. Click the Backup menu.
3. When the backup settings list appears, check the required information.
   
   • DB service name: service name specified by user
   • Backup retention period: maximum number of days for the backup file to be stored in data storage
   • Backup start time: time at which the backup is performed once a day
   • Backup data size: size of the completed backup file
   • Latest successful backup date: date for the latest backup that was performed
   • View details: details and restoration of the backup file list created per server, saved to Object Storage

Check backup file list per server

The following describes how to check the backup file list created for each server after completing the backup:

1. Click the Services > Database > Cloud DB for MongoDB menus from the VPC environment of NAVER Cloud Platform console, in that order.
2. Click the Backup menu.
3. Click the [Details] button from View details of the backup settings row you want to check the details for.
4. Check the details for the backup file.
   
   • Backup date: date that the backup was performed
   • Shard (replica set): shard that performed the backup
   • Backup start time: time when the backup was started
   • Backup completion time: time when the backup was completed
   • Elapsed time: time it took for the backup to be completed
   • Backup size: size of the created backup file upon completion of backup
   • Data storage: data storage usage of the shard that performed the backup
     • You can check the required storage size when you need to perform a restoration using the backup.

Restoration

Cloud DB for MongoDB provides a service that enables you to restore lost data using backup files, and easily and quickly create a MongoDB server. It allows the user to restore the data up to the desired time within the range available for recovery. The following describes how to restore it.

1. Click the Services > Database > Cloud DB for MongoDB menus from the VPC environment of NAVER Cloud Platform console, in that order.
2. Click the Backup menu.
3. Click the [Details] button of the backup settings row you want to restore.
4. Select the item to restore and click the [Restore backup file] button.
   
5. When the Restore backup pop-up window appears, check or enter the required information for restoration
   • Backup time: check the backup completion time
   • MongoDB Cluster Type: select the MongoDB cluster type
   • DB server name: enter the name of the MongoDB server to restore
     • The name must be 3-15 characters long and can only include Korean letters, English letters, numbers, and the hyphen (-)
     • A duplicated name can't be used
     • It is created with random text added to avoid a duplicated host name.
