TDSQL-C for MySQL can roll back databases/tables to an original cluster and roll back an entire cluster (clone) to a new cluster. You can choose different rollback methods according to your business needs. This document describes how to roll back certain databases/tables in the original cluster.
Rollback Method
- Rollback by backup file: this method restores the cluster to the dataset state of a backup file. The selection range of the backup file is determined by the data backup retention period you set.
- Rollback by time point: this method restores the cluster to any time point within the log backup retention period you set.
Directions
- Log in to the TDSQL-C for MySQL console and click a cluster name in the cluster list to enter the cluster management page.
- On the cluster management page, select the Backup Management tab and click Rollback.

- On the database/table rollback page, select the database/table to be rolled back, rename it, and click Rollback.
- For database/table rollback, you need to specify the database/table to be rolled back. If you cannot determine all the involved databases/tables, we recommend you clone the original cluster and migrate back to it after determining the databases/tables.
- If the database/table to be rolled back does not exist at the specified time point, database/table rollback will fail.
- If the database/table to be rolled back does not exist or has been dropped, you need to log in to the database and create a database/table first before performing rollback in the console.
- If there are primary or foreign key constraints in the specified database/table to be rolled back, please ensure that the associated databases/tables exist during the rollback process; otherwise, database/table rollback will fail.
- Up to 500 databases or tables can be rolled back at a time.

- In the pop-up window, confirm that everything is correct and click OK to initiate the rollback task.
- After the task is submitted, you can click View Rollback Task or go to the task list to view the rollback progress and task details.

- After the rollback is completed, you can see the new restored database/table in the original cluster and perform further operations.
