Migrating Data from a Self-Managed SQL Server Database on an ECS to an RDS for SQL Server DB Instance Scenarios You have created a Microsoft SQL Server database on an ECS. The self-managed SQL Server database version on the ECS cannot be later than the version of the RDS for SQL Server
RDS uses Elastic Volume Service (EVS) disks for storage. For details, see Elastic Volume Service Service Overview. The RDS backup data is stored in OBS and does not occupy the database storage space.
The supported IOPS depends on the I/O performance of Elastic Volume Service (EVS) disks. For details, see the description about ultra-high I/O in Disk Types and Performance of Elastic Volume Service Service Overview.
What Should I Do If an ECS Cannot Connect to an RDS for SQL Server Instance Through a Private Network? Perform the following steps to identify the problem: Check whether the ECS and RDS for SQL Server instance are located in the same VPC. If they are in the same VPC, go to 2. If they
The supported IOPS depends on the I/O performance of the Elastic Volume Service (EVS) disk. For details, see "Ultra-high I/O" in Disk Types and Performance of the Elastic Volume Service Service Overview.
Will My Access Be Restricted by Bandwidth When I Connect to My RDS for SQL Server Instance from an ECS over a Private Network? No. Parent Topic: Database Connection
Connecting to a DB Instance from a Windows ECS over a Private Network When your applications are deployed on an ECS that is in the same region and VPC as your RDS for SQL Server DB instance, you are advised to use a floating IP address to connect to the DB instance through the ECS
Data reliability For details, see What Is EVS? Requires device procurement, primary/standby relationship setup, and RAID setup. Database backup Supports automated backups, manual backups, and custom backup retention periods. Requires device procurement, setup, and maintenance.
IOPS Cloud SSD: a maximum of 50,000 Extreme SSD: a maximum of 128,000 The input/output operations per second (IOPS) supported depends on the I/O performance of Elastic Volume Service (EVS) disks.
How Can I Back Up an RDS for SQL Server Database to an ECS? You can back up data to an ECS the same way you export SQL statements. The ECS service does not have restrictions on the types of data to be backed up as long as the data complies with local laws and regulations. You can
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.
Resilience RDS for SQL Server uses EVS disks to store data, providing three-copy storage and 99.9999999% data durability. It also provides features like cross-region replication and intra-AZ anti-affinity, to guarantee reliability and availability of your instances.
