SQL Server Data Backup
Last updated: 2025-07-10 15:20:32
Overview
SQL Server data backup is a SCF-based database backup feature provided by COS. It allows you to dump SQL Server data to COS so that data can be stored persistently and protected from data loss or corruption. After you set a backup function rule for a specified bucket, SCF will scan your server backup files periodically and dump them in the bucket.
Notes
SQL Server data backup functions back up only the backup files of SQL Server. If SQL Server backup is not enabled, the backup functions cannot be executed. For more information about Tencent Cloud SQL Server database backup, please refer to Backup Cloud Database SQL Server.
If you have added a SQL Server data backup rule to your bucket in the COS console, you can view it in the SCF console. DO NOT delete the function. Otherwise, your rule may not take effect.
The current feature is only supported in regions where both COS and SCF are the same. It is not supported in some regions, such as Chongqing. The specific regions are subject to those displayed on the COS and SCF consoles.
Directions
1. Log in to the COS console.
2. On the left sidebar, click Application Integration > Data Backup.
3. Find SQL Server Backup and click Configure Backup Rule to go to the rule configuration page.
4. Click Add Function.
Note:
If you haven't activated SCF, go to the SCF console to activate it and authorize the service as instructed.
5. In the pop-up window, configure the following items:
Function Name | Uniquely identifies a function and cannot be modified after being set. You can view the function in the SCF console. |
