Creating an Azure Blob Storage Virtual Client with IAM VM Role Assignment

To back up an Azure Blob object storage virtual client with IAM (Identity and Access Management) virtual machine (VM) role assignment, you need to first assign the storage blob data owner role to the Azure VM that you will use as access node to back up storage account, and then, using the IAM VM role assignment type of authentication, add an Azure Blob storage virtual client with that VM as access node.

Assign the Storage Blob Data Owner Role to the VM

  1. In the Azure portal, using the Azure subscription that is going to be associate to the VM, create or select a Windows or UNIX VM.

  2. Turn the system assigned identity on at Azure VM level.

  3. In the Azure Blob Storage account, add the storage blob data owner role to the Azure VM which will be used as access node.

Add the Virtual Client with IAM VM Role Assignment

  1. From the CommCell Browser, right-click Client Computers, and then click New Client > Cloud Storage > Azure BLOB.

    The New Azure Storage Client dialog box appears.

  2. On the General tab, provide the following details:

    1. In the Client Name box, type a name for the new virtual client.

    2. In the Instance Name box, type a name for the instance.

    3. In the Access Node box, select one or more Azure VMs with storage blob data owner as proxy client computer, or the client group of Azure VMs where the Cloud Apps package is installed.

      Note

      • The proxy client computers must be of similar operating system type.

      • All clients in the client group must be reachable through network routes.

    4. In the Storage Policy box, select a storage policy for the backup and restore operations.

    5. In the Number of Data Backup Streams box, type the number of data streams to use for backups. The maximum value is 99.

      Note: The number of streams must not exceed the maximum number configured in the subclient storage policy. The CommServe allocates streams depending on the availability of resources.

  3. On the Connection Details tab, enter the following details:

    1. In the Host URL box, enter the Azure Blob Storage service account URL, for example, blob.core.windows.net.

      To back up Azure File shares in the Azure Storage service account, enter the Azure File Share URL, for example, file.core.windows.net.

    2. From the Authentication Type list, select IAM VM role assignment.

    3. In the Account name box, enter the name of the Azure Blob Storage account.

  4. Click OK.

Results

The Commvault software creates an Azure Blob Storage virtual client that contains a default instance.
