TDSQL-C can [roll back databases/tables] to an original cluster (https://intl.cloud.tencent.com/document/product/1098/40634) 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 clone a cluster in the TDSQL-C console to quickly roll back an instance into a new cluster.

TDSQL-C provides the clone feature, which can restore a cluster to any time point in the log backup retention period or to the backup set of the specified backup file through clone.
The clone will create a new cluster based on your choice. After the new cluster is verified, you can directly use the cloned new cluster.

Note：

Billing will start for the cloned new cluster after the clone succeeds. For more information on billing and pricing, please see Billing Overview.
