Restoring a Single Node Instance from a Backup

Scenarios

This section describes how to restore a single node instance from a backup.

Restoration Precautions

  • When you restore the DB instance from a backup file, a full backup file is downloaded from OBS and then restored to the DB instance at an average speed of 40 MB/s.

Method 1

  1. Log in to the DDS console.
  2. On the Instance Management page, click the target single node instance.
  3. In the navigation pane on the left, click Backups & Restorations.
  4. On the Backups & Restorations page, locate the target backup and click Restore in the Operation column.
  5. In the displayed window, select a restoration mode and click OK.

    • Create New Instance

      The Create New Instance page is displayed for you to create a DB instance using the backup data. The new DB instance is independent from the original one.

      • The database type, DB instance type, compatible MongoDB version, storage engine, and storage type must be the same as those of the original and cannot be changed.
      • The storage space is the same as that of the original instance by default. You can only increase the storage space.
      • Other settings have default values and can be modified. For details, see section Creating a Single Node Instance.
    • Restore to Original
      • Restoring to the original DB instance will overwrite all existing data and the DB instance will be temporarily unavailable during the restoration.
      • The administrator password of the database instance remains unchanged after the restoration.

Method 2

  1. Log in to the DDS console.
  2. In the navigation pane on the left, click Backup Management.
  3. On the Backup Management page, locate the target backup on the Single Nodes tab and click Restore in the Operation column.
  4. In the displayed window, select a restoration mode and click OK.
