This topic describes how to restore the data of an ApsaraDB RDS for SQL Server instance across regions. You can restore data from a cross-region backup file to a new RDS instance that resides in the same region as the file. This requires that you have backed up your RDS instance across regions.
Restore data to a new RDS instance
- In the left-side navigation pane, click Cross-region Backup.
- In the top navigation bar, select the region where the original RDS instance resides.
- Find the original RDS instance and click its ID.
- On the Data Backup tab, find the backup set that you want to use, and click Restore in the Actions column.
- Select Restore to New Instance and click OK.
- On the Restore Database page, click the Subscription or Pay-As-You-Go tab and configure the following parameters.
Parameter Description Restore Mode
- By Backup Set: allows you to restore data from a backup set.
- By Time: allows you to restore data to a point in time. The point in time must be within the specified log backup retention period.
Backup Set The backup set from which you want to restore data. This parameter appears only when you set Restore Mode to By Backup Set. Restore Point The point in time to which you want to restore data. This parameter appears only when you set Restore Mode to By Time.Note Both local and cross-region log backups can be used to restore data to a point in time. Region The region to which the new RDS instance belongs.Note You can select only the region to which the cross-region backup files of the original RDS instance are stored. Zone The zone where the new RDS instance resides. Each zone is an independent physical location within a region. Zones in the same region provide the same services. You can create the new RDS instance in the same zone as the ECS instance to which you want to connect or in a different zone. CPU and Memory The specifications of the new RDS instance. Each instance type supports a specific number of CPU cores, memory capacity, maximum number of connections, and maximum input/output operations per second (IOPS). For more information, see Primary instance types. Capacity The storage capacity that the new RDS instance has available to store data files, system files, archived log files, and transaction files. Network Type
Note The settings of some parameters cannot be modified. These parameters include Database Engine, Version, and Edition. The same settings of these parameters must be specified for the original and new RDS instances.
- Classic Network: the traditional type of network.
- VPC: the recommended type of network. A virtual private cloud (VPC) is an isolated virtual network that provides higher security and better performance than the classic network. If you select the VPC network type, you must also select a vSwitch that is associated with the specified VPC.
- Specify the Duration and Quantity parameters. Then, click Buy Now. You must specify the Duration parameter when the new RDS instance uses the subscription billing method.
After you create an RDS instance, you must configure IP address whitelists or security groups and create accounts. For more information, see Configure a whitelist for an ApsaraDB RDS for SQL Server instance and Create an account on an ApsaraDB RDS for SQL Server instance. If you want to connect to the RDS instance over the Internet, you must also apply for a public endpoint. For more information, see Apply for or release a public endpoint on an ApsaraDB RDS for SQL Server instance. After you complete these operations, you can connect to the RDS instance. For more information, see Connect to an ApsaraDB RDS for SQL Server instance.
