Downloading a Backup File

Scenarios

This section describes how to download a manual backup, an unsynchronized backup, or an automated backup to a local device and restore data from the backup file.

Constraints

• Unsynchronized backups are generated only for DB instances running Microsoft SQL Server 2017 Enterprise Edition. If a primary DB instance fails, the standby DB instance is promoted to the new primary instance. During the failover process, a small amount of data may not be synchronized and a differential backup is created for user-created databases on the original primary DB instance. For more information, see How Are Unsynchronized Backups Generated for RDS SQL Server DB Instances?
• If the size of the backup data is greater than 400 MB, you are advised to use OBS Browser+ to download the backup data.
• When you use OBS Browser+ to download backup data, there is no charge for the generated outbound traffic.

Method 1: Using OBS Browser+

1. Log in to the management console.
2. Click in the upper left corner and select a region.
3. Click in the upper left corner of the page and choose Databases > Relational Database Service.
4. On the Backups page, locate the backup to be downloaded and click Download in the Operation column.

   Alternatively, click the target DB instance. In the navigation pane on the left, choose Backups & Restorations. On the displayed page, locate the target backup to be downloaded and click Download in the Operation column.

5. If you have enabled operation protection, click Send Code in the displayed Identity Verification dialog box and enter the obtained verification code. Then, click OK.

   Two-factor authentication improves the security of your account. For details about how to enable operation protection, see Identity and Access Management User Guide.

6. In the displayed dialog box, select Use OBS Browser+ for Download Method and click OK.

      If you want to access OBS external buckets across accounts, the access permission is required. For details, see Granting IAM Users Under an Account the Access to a Bucket and Resources in the Bucket.

   5. Download the backup file.

      On the OBS Browser+ page, click the bucket that you added. In the search box on the right of the object list page, enter the backup file name provided in step 3 on the download guide page. In the search result, locate the target backup and click in the Operation column.

   In the displayed dialog box, select Use Download URL for Download Method, click to copy the URL, and enter the URL in your browser.

   For Microsoft SQL Server DB instances, the URLs of all the backup files are displayed. You can download the backup files of a specific database.

   • You can use other download tools to download backup files.
   • You can also run the following command to download backup files:

     wget -O FILE_NAME --no-check-certificate "DOWNLOAD_URL"

     Variables in the commands are as follows:

     FILE_NAME: indicates the new backup file name after the download is successful. The original backup file name may be too long and exceed the maximum characters allowed by the client file system. You are advised to use the -O argument with wget to rename the backup file.

     DOWNLOAD_URL: indicates the path of the backup file to be downloaded. If the path contains special characters, escape is required.
