This topic describes how to query data in a single backup set that is generated by Database Backup (DBS).


Multiple backup sets are generated based on a database that runs the MySQL, SQL Server, Oracle, PostgreSQL, Postgres Plus Advanced Server (PPAS), or PolarDB-X engine.
Note The database can be a self-managed database, an ApsaraDB RDS database, or a PolarDB database, but cannot be a PolarDB O Edition database.


  1. Log on to the DBS console.
  2. In the left-side navigation pane, click Backup Schedules. On the Backup Schedules page, select a region in the upper-left corner.
  3. On the Backup Schedules page, find the backup schedule for which the backup set that you want to query is generated. Then, click Manage in the Actions column.
  4. In the left-side navigation pane, choose Backup Tasks > Full Data.
  5. On the page that appears, find the backup set that you want to query and click Query Backup Set in the Actions column.

  6. In the Query Backup Set message, click OK.

    You are navigated to the DLA console.
  7. In the left-side navigation pane of the DLA console, choose Serverless Presto > Execute. DLA creates a database based on the schema of the selected backup set and displays the database in the navigation tree of the Execute page. Double-click the database name, enter an SQL statement in the code editor, and then click Sync Execute.
    Note The SQL syntax of DLA is based on Presto. For more information, click Syntax Manuals in the upper-right corner of the Execute page or see Common SQL statements.
