Database Backup allows you to physically back up and restore an ApsaraDB for Redis instance.


The ApsaraDB for Redis instance uses Redis 4.0 or 5.0 and the cluster architecture.


This feature is in public preview. To use this feature, join the DingTalk group whose ID is 32596162.

Step 1: Add a data source

Data sources are databases or file paths to be backed up. The data source information includes data source names, regions where data sources are located, database engines, and database accounts and passwords.

For more information, see Add a data source.

Note When you add a data source, set Data source category to Cloud database and Instance type to ApsaraDB for Redis.

Step 2: Create a backup policy

The settings of a backup policy contain the backup method, storage method, backup frequency, backup cycle, and backup start time. For more information, see Create a backup policy.

Note When you create a backup policy, select Physical Backup. For more information, see Backup methods.

Step 3: Back up a database

  1. Log on to the DBS console.
  2. In the left-side navigation pane, click Data Source. On the Data Source page, select a region in the upper-left corner.
    Select a region
  3. Click Batch backup.
    Batch backup
  4. Set Database Source Type to Redis, set Backup Method to Physical Backup, and then click Start Batch Backup.

    The system lists the available data sources that meet the specified conditions.

  5. Note
    • You can select a single database in this step.
    • The batch backup feature does not allow you to select data sources across multiple pages. By default, 20 data sources are displayed on each page. If you need to back up more than 20 data sources, we recommend that you perform multiple batch backups.
    • To search for a data source, you can enter the name of the data source in the search box. You can also filter the data source based on the logical group to which the data source belongs.
    • If the database account and password are not configured for the data source that you want to back up, you must configure the account and password. For more information, see Configure the account and password for a data source.

  6. Note
    • You can use the physical backup method to back up an entire instance.
    • You can click One-click backup to back up all databases and tables in an instance.
  7. In the Backup Configuration step, select a backup schedule specification, modify the backup configurations, and then click NextBackup Strategy.
    1. Click Select the specifications. In the dialog box that appears, select a backup schedule specification and click OK.
      Select the specifications.
      • The backup schedule specification that you select applies to all data sources that you add in this batch backup. You cannot select a backup schedule specification for each data source.
      • The free quota for data backup, unit price, and backup and restoration performance vary based on backup schedule specifications. For more information, see Select backup schedule specifications.
    2. Click Modify the backup configuration in bulk. In the dialog box that appears, modify the following parameters and click OK.
      Category Parameter Description
      The underlying configuration maximum number of parallel threads for a full backup The maximum number of concurrent threads available for a full data backup.
      Note The maximum number of actual concurrent threads varies based on backup schedule specifications.
      Incremental log real-time backup Specifies whether to enable incremental backup.
      Advanced configuration None None
      Note To modify the backup configurations, you can also click Modify the backup configuration in the Actions column.
  8. In the Backup Strategy step, click Batch apply backup strategies. In the dialog box that appears, select the backup policy that you created in Step 2 and click OK. Then, click NextPurchase Schedule.
    Note To modify a backup policy, you can click Select an option in the Backup Strategy column.

  9. After the payment is successful, the system starts to configure the backup schedule and perform a precheck. A precheck includes initializing the backup schedule and checking the configuration environment.

    Note The precheck takes about 2 minutes. A larger data source requires more time. Click Precheck Progress to view the precheck progress.

  10. After you click Complete, the system automatically starts the backup schedule. You can view the created backup schedule on the details page of the destination instance.
