    Data Management:Manually initiate a backup task

    Last Updated:Mar 07, 2025

    Data Disaster Recovery runs backup tasks based on the backup policy of a backup schedule. You can also manually initiate a backup task. This topic describes how to manually initiate a backup task.

    Prerequisites

    • The data source is one of the following databases:

      • Alibaba Cloud databases: ApsaraDB RDS for MySQL, ApsaraDB RDS for PostgreSQL, ApsaraDB RDS for SQL Server, and PolarDB for MySQL

      • Self-managed databases hosted on Elastic Compute Service (ECS) instances: MySQL

      • On-premises databases, and cloud databases from third-party providers: MySQL

    • The backup policy is configured for the data source. For more information, see Purchase a backup instance.

    Usage notes

    • After you manually initiate a backup task, the system checks whether a full backup task is running. If so, we recommend that you do not initiate a new backup task. In other cases, a new full backup task is created and started. You can manually initiate a backup task after the current backup task is complete.

    • When Data Disaster Recovery backs up a database, the performance of the source database is affected. We recommend that you run backup tasks during off-peak hours.

    Pricing

    When you manually initiate a backup task, Data Disaster Recovery charges you backup fees and storage fees of backup sets. You cannot use resource plans to offset the fees.

    Billable item
