You can configure your own Azure Storage Account (BYOS) in Commvault Cloud as cloud storage. If you configure network connectivity for your Azure storage account using either Public Network Access (selected networks) or the Private Link, then Commvault Cloud cannot access your Azure storage to store your backup.
Configure Azure Storage Using Public Network Access (Selected Networks) for Network Connectivity
If Commvault Cloud and your Azure (BYOS) storage account are in the same region (or a paired region), then the data flow between them always uses the VNET IP address (private IP address) for communication. So Commvault Cloud cannot access your Azure Storage if you only configure a public IP address using firewall rules on your Azure storage account.
To configure restricted Azure BYOS storage for Commvault Cloud, you must add Commvault Cloud as a resource to your Azure Virtual Network (VNET).
You can configure Commvault Cloud subnet resource ID on your storage account using the following Azure CLI command:
az storage account network-rule add --resource-group “customer_resource_group_name” --account-name “customer_storage_account_name” --subnet "subnet_ID "For Azure CLI command, see Steps to create cloud storage for the primary copy.
Configure Azure Storage Using Private Link for Network Connectivity (Requires Support Assistance)
To give Commvault Cloud access to Azure resources that are configured with a private link as a source or a target, you must use a backup gateway.
Verify that the storage account is accessible from the VNET that is used for the backup gateway.
To install the backup gateway, see Commvault Cloud Backup Gateway.
