How Can I Back Up a TaurusDB Database to an ECS? Why Did My Automated Backup Fail? How Is TaurusDB Backup Data Billed?
Create a TaurusDB instance and an ECS in the same VPC and access the TaurusDB instance through the ECS. For details, see: Connecting to a DB Instance over a Private Network Parent Topic: Database Connections
Ensure that the ECS is in the same region, AZ, VPC, and security group as a TaurusDB instance. Data disks are not required. Log in to the ECS and download and install a MySQL client.
What Should I Do If an ECS Can't Connect to a TaurusDB Instance? Can an External Server Access a TaurusDB Instance? What Is the Maximum Number of Connections to a TaurusDB Instance? What Do I Do If There Are Too Many Database Connections?
When you attempt to connect to a TaurusDB instance through a private network, check whether the ECS and TaurusDB instance are in the same security group. If they are in the same security group, they can communicate with each other by default.
When you create an ECS, select an OS, such as Red Hat 6.6, and bind an EIP to it. Then, upload the installation package to the ECS using a remote connection tool, and use PuTTY to connect to the ECS.
Table 1 Related services Service Description Elastic Cloud Service (ECS) Enables you to access TaurusDB through an internal network. You can then access applications faster and you do not need to pay for public network traffic.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), can all be shared within a given region. Regions can be universal or dedicated.
To achieve a higher transmission rate and security level, you are advised to migrate your applications to the ECS that is in the same region as the TaurusDB instance. After an EIP billed on a pay-per-use basis is unbound from a TaurusDB instance, it is still billed.
If you are accessing the instance through an ECS, instance_ip is the private IP address of the instance. You can view the private IP address in the Network Information area on the Basic Information page.
Connecting a DB instance over the private IP address If your application is deployed on an ECS that is in the same region and VPC as a DB instance, you are advised to use the private IP address of the DB instance to connect to the ECS for high security and performance.

If you are accessing the instance through an ECS, instance_ip is the private IP address of the instance. You can view the private IP address in the Network Information area on the Basic Information page.

By default, a TaurusDB instance cannot be accessed by an ECS in a different security group. To enable access, you must add an inbound rule to the security group of a TaurusDB instance.
