Zorluk: OrtaAzure Files Backup and Restore

You have an Azure subscription that contains a Recovery Services vault named `rsv-backup-prod` and a Premium storage account named `safilesprod` in the West US region. The storage account hosts an SMB file share named `share-hr`. Daily backups for `share-hr` are configured in `rsv-backup-prod`.

The firewall for `safilesprod` is configured to allow access only from selected networks. An administrator named Liam is assigned the Backup Operator role for `rsv-backup-prod` and the Reader role for `safilesprod`.

Liam attempts to restore a set of deleted files from a daily backup to the original location, but the restore operation fails with a network access error.

What should you configure to resolve the issue?

  1. Configure the firewall of `safilesprod` to allow trusted Microsoft services to access the storage account.Cevap
  2. B
    Assign Liam the Storage File Data Privileged Contributor role on `safilesprod`.
  3. C
    Add the public IP address of the client computer Liam is using to the firewall rules of `safilesprod`.
  4. D
    Configure the private endpoint of `safilesprod` to allow inbound traffic from the subnet hosting the Recovery Services vault.

Cevap

Configure the firewall of the storage account to allow trusted Microsoft services to access the storage account.
The correct option is to configure the firewall of the storage account to allow trusted Microsoft services to access the storage account. When a storage account firewall is configured to restrict access to selected networks, the Azure Backup service (which runs as a trusted Microsoft service) requires this exception to bypass the firewall and perform backup or restore operations on the Azure file share.

Adım Adım Çözüm

1
Identify the cause of the failure based on the network access error.
The firewall of the storage account restricts access to selected networks, blocking the Azure Backup service.
Azure Backup runs as a trusted Microsoft service outside the customer's private virtual network.
2
Enable the firewall bypass exception on the storage account.
The option 'Allow trusted Microsoft services to access this storage account' is enabled on the storage account firewall settings.
This allows the Azure Backup service to bypass the network restrictions and successfully perform the restore operation.
