Amazon Web Services User Permissions for Backups and Restores


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.

If you are performing backups to an S3 library, also add Amazon S3 permissions.

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:

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.

For more information about AWS permissions, in the AWS documentation, see Amazon Elastic Compute Cloud API Reference or Amazon Simple Storage Service API Reference.
