TencentDB for MariaDB can roll back data to any time point in the last 30 days based on the retention of backups and logs. With the database rollback feature, system loss can be minimized.
The rollback feature of TencentDB for MariaDB does not affect a production instance and can directly roll back data to a temp instance created by Tencent Cloud, which supports read/write operations, so that you can modify the temp instance in a more flexible manner, such as clearing dirty data. After correcting the data in the temp instance, you can use "instance switch" to convert the temp instance to the production instance.
A temp instance is an instance created by TencentDB for MariaDB based on backup and used for only temporary adjustment. It has the following features:
After rollback, you can view the generated temp instance on the Backup and Restore > Temp Instance page.
Instance switch refers to switching a temp instance to the production environment. You can switch the temp instance after confirming that the data rolled back is correct. The switch will change the private network links in the original and temp instances.
You can click Migrate temp instance to the network production environment on the Backup and Restore > Temp Instance page.
