Configuring AWS Native Snapshot Backups for Amazon RDS Instances with IAM Role Authentication

You can configure AWS native snapshot backups for Amazon RDS instances using an IAM role. The configuration wizard guides you through the configuration process, which includes creating any new entities that are needed, such as a backup plan, cloud storage, cloud account, and backup content..

Start the Configuration Wizard

1. From the navigation pane, go to Protect > Databases.

   The Overview page appears.

2. In the upper-right area of the page, click Add instance, and then select Cloud database service.

   The Add Cloud DB Instance dialog box appears.

3. Select Amazon Web Services and then click NEXT.

   The Configure Amazon Database dialog box appears.

4. Select RDS (Snapshot) and then click NEXT.

   The Select Backup Method page appears.

Select "Back up using the gateway(s)"

1. Select Back up using the gateway(s).

2. Click NEXT.

The Configure Permissions page of the Configure Amazon database - RDS (Snapshot) configuration wizard appears.

Configure Permissions

1. From the Authentication method list, select IAM role.

2. Verify an existing CommvaultRole IAM role or create a new CommvaultRole IAM role:

   • If the CommvaultRole IAM role was previously created for another AWS workload, do the following:

     1. Verify that the IAM policies for the AWS workload are still attached to the CommvaultRole IAM role.

     2. At the bottom of the page, select the confirmation check box.

     3. Click NEXT.

        The Region page appears.

   • If the CommvaultRole IAM role does not exist yet, create it in AWS.

     Steps to create the CommvaultRole IAM role

     1. Click the Launch CloudFormation Stack link to open the AWS console.

        Important

        If you do not have permission to create a role in the AWS account, copy the Launch CloudFormation Stack link and share it with your AWS IAM administrator.

     2. Log on to the AWS console.

        The Quick create stack page appears.

     3. Under Capabilities, read the information about the template, and then select the acknowledgment check box.

     4. Click Create stack.

        Wait for the CloudFormation Stack to finish creating the CommvaultRole IAM Role. The CloudFormation Stack creates IAM policies for all supported AWS workloads, and then attaches the policies to CommvaultRole.

     5. Return to the Commvault Cloud configuration wizard.

     6. At the bottom of the page, select the confirmation check box.

     7. Click NEXT.

        The Region page of the configuration wizard appears.

Region

1. Select the region that the RDS instances reside in.

2. Click NEXT.

   The Backup Gateway page of the configuration wizard appears.

Backup Gateway

• If AWS EBS encryption is enabled for your region in your AWS account, the user who uses the backup gateway template must be a key user for the default encryption key. To see if EBS encryption is enabled, in your AWS account, go to EC2 > EC2 Dashboard > Settings > EBS encryption. To see a list of key users for the default encryption key, in your AWS account, go to Key Management Service > Customer managed keys. If you do not have the correct level of access to use the template, you can copy the Launch Cloud Formation Stack link and share it with someone who has the correct level of access, such as your security administrator.

• Determine the region of your AWS S3 storage. The backup gateway must reside in the same region as the primary storage.

• Select an existing backup gateway or create a new backup gateway.

  Steps to create a backup gateway

  1. Click the add button .

     The Add a new backup gateway dialog box appears.

  2. For Platform, select the OS for the backup gateway.

     An AWS CloudFormation template is created based on the region and the operating system that you selected.

  4. Click the CloudFormation link to open the AWS console.

     Note

     If AWS EBS encryption is enabled for your region in your AWS account, to use the template, you must be a key user for the default encryption key. If you are not a key user for the default encryption key, copy the CloudFormation link and share it with someone who is a key user, such as your security administrator.
