Commvault requires access to your AWS account via AWS Identity and Access Management (IAM) policies which are associated with IAM Roles or users. For more information, on the AWS documentation site, see Policies and permissions in IAM.
For Commvault to perform backup and restores of AWS resources, you must grant permission for Commvault via an IAM User or Role with the IAM policies defined below:
Use the following IAM policy definitions to configure your IAM Roles and Users:
AWS service to protect | AWS IAM policy |
|---|---|
Amazon Compute Cloud (Amazon EC2) | amazon_restricted_role_permissions.json (recommended) |
Amazon Compute Cloud (Amazon EC2) | amazon_permission_backup_restore.json (alternate, wider permission set) |
Amazon Relational Database Service (Amazon RDS) | |
Amazon Redshift | |
Amazon DocumentDB | |
Amazon DynamoDB | |
Amazon S3 on Outposts | |
Amazon Compute Cloud (EC2) with databases, file systems, and application agents | |
Additional AWS service to protect | AWS IAM policy |
Virtual Machine conversion to Amazon EC2 | |

How Commvault Uses AWS Permissions
Commvault uses Amazon Web Services (AWS) permissions to perform data protection and data recovery operations for instances that run in AWS. These permissions are used only to access snapshots, volumes, and instance configuration information that are required to back up instances to storage media, to recover instances, and to clean up intermediate entities that are created by Commvault during those operations. In cases where a user with the required administrative privileges requests that a recovered instance overwrites the original instance, the permissions are also used to remove the original instance, but only after confirmation from the user.
Commvault usage of AWS permissions is controlled by the account settings that are used to create a virtualization client (hypervisor). To perform authentication, the virtualization client can use IAM roles or an access key and secret key pair to access the AWS account.
Note: When using resources from an Admin Account, you must add JSON permissions to both Admin and Tenant accounts.
For information about how Commvault uses each permission, see Amazon Web Services Permission Usage.
