Configuring Backups for Amazon DocumentDB Instances with IAM Role Authentication

You can configure backups for Amazon DocumentDB 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 plan and cloud storage.

Start the Configuration Wizard

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

   The database overview page appears.

2. Click Add Instance, and then click Cloud database service.

   The Vendor page appears.

3. Select Amazon Web Services and then click NEXT.

   The Select a Database Service page appears.

4. Select DocumentDB 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 - DocumentDB configuration wizard appears.

Configure Permissions

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

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

   • If the MetallicRole 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 MetallicRole IAM role.

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

     3. Click NEXT.

        The Region page of the configuration wizard appears.

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

     Steps to create MetallicRole 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 MetallicRole IAM Role. The CloudFormation Stack creates IAM policies for all supported AWS workloads, and then attaches the policies to MetallicRole.

     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

   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.
