Role and Permission Requirements for Protecting Azure Resources

For most Azure resources, Commvault provides a custom role that includes the permissions that are required to protect the resources. In non-production environments, you can use Azure built-in roles instead. For VMs encrypted with Azure Key Vault, you can use a custom role or an access policy, but access policies are less secure and are considered by Microsoft to be a legacy authorization system.

If there is no custom role for an Azure resource that you want to protect, you can create your own custom role.

For instructions to assign roles, see Assign Azure roles using the Azure portal.

Custom Roles

Important

In the JSON file, change placeholder values such as {subscription-id}.

Azure Cosmos DB for Cassandra, MongoDB, NoSQL, and Table Azure Database for MariaDB, MySQL, and PostgreSQL Azure SQL Database Azure SQL Managed Instance Azure Table Storage	AzureDBBackupRole.json	AzureDBBackupRole_CLI.json
Azure VMs	CVBackupRole.json	CVBackupRole_CLI.json
Azure Blob Storage Azure Data Lake Storage Gen2	AzureBlobADLSGen2BackupRole.json	None
Azure File Storage	AzureFileBackupRole.json	None

Built-In Roles

Azure File Storage	Storage Account Contributor	Storage Blob Data Contributor Storage File Data Privileged Contributor

Permissions for Azure Key Vault Access Policies

For Azure VMs that are encrypted with Key Vault, instead of using a custom role that you assign to your Azure Key Vault application, you can create an access policy and assign it to the Azure VM or the Azure Key Vault application that functions as your service principal.

For instructions to create an access policy in the Azure portal, see Assign a Key Vault access policy (legacy).

Azure resources	Permissions to select for both Key permissions and Secret permissions
VMs, encrypted with Azure Key Vault	Get Recover Backup Restore

Create Key Vault access policy

Note

The Commvault Cloud software does not support VMs that are encrypted with Azure Key Vault for managing certificates.
