TencentDB for Redis Memory Edition master and replica instances (except v2.8) allow you to clone a complete instance from a backup file in both single-AZ and multi-AZ deployments. The clone instance has the same data as the backup file. You can use the clone feature to analyze historical data. You can also roll back an instance by swapping the IPs of the clone and original instances.
The instance data has been backed up. For backup directions, see Backing up Data.
After the instance is cloned, the original instance can be retained or terminated based on your needs.
