    ApsaraDB RDS:Download data backup files and log backup files

    Last Updated:Aug 29, 2023

    This topic describes how to download the unencrypted data backup files and log backup files of an ApsaraDB RDS for SQL Server instance. You can archive the backup files that you download and use the backup files to restore data to on-premises databases.

    Note

    For more information about the data backup and log backup features, see Back up an ApsaraDB RDS for SQL Server instance.

    Limits

    • If the AliyunRDSReadOnlyAccess policy is attached to a RAM user, the RAM user has only the read permissions and cannot download data backup files or log backup files. You must attach the AliyunRDSFullAccess policy to the RAM user.

    • Backup files that are generated by using the snapshot backup feature cannot be downloaded. For more information, see Enable the snapshot backup feature.

    Billing rules

    If you download backup files over the Internet, you are charged for the traffic that you consume.

    • Downloads over an internal network: You are not charged for the traffic that you consume.

    • Downloads over the Internet: After the free quota of 500 GB per instance-month is exhausted, you are charged for the excess traffic that you consume based on the pay-as-you-go billing method. Fees are deducted from your account on a daily basis. For more information, see Network traffic fees.

    Note

    • If the download task fails, you are not charged for the traffic.

    • To view the volume of traffic that you consumed to download backup files over the Internet, you can log on to the ApsaraDB RDS console, go to the Instances page, click the ID of your RDS instance to go to the Basic Information page, and then view the Backup Usage parameter in the Usage Statistics section of the page.

    Download full or incremental physical backup files

    1. Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.

    3. On the Base Backups tab, click the Data Backup tab.

    4. Specify the time range that you want to query.

      Note

      • If Download Instance Backup cannot be found in the Actions column, resolve the issue based on the description in Limits.

      • If you want to download a data backup file and use the file to restore data, we recommend that you select the data backup file that is created at the point in time closest to the point in time to which you want to restore data.

      • If you want to download a log backup file and use the file to restore data to an on-premises database, the start time of the log backup file must be within a specific time range. The time range starts after the point in time at which the selected data backup file is generated and ends before the point in time to which you want to restore data.

    6. In the dialog box that appears, read and select the description and click Download or copy the URL that you can use to download the backup file.

      • Internal URL: If your virtual private cloud (VPC)-type Elastic Compute Service (ECS) instance can communicate with the RDS instance over an internal network, you can log on to your ECS instance and use the internal URL to download the backup file. This method is faster and more secure.

      • Public URL: If the RDS instance cannot be connected over an internal network, you can use the public URL to download the backup file.
