Windows Server Backup and SQL Server 2012

Hi,
We have hyper-v virtual machine with installed SQL Server 2012 on Windows Server 2012 R2. This machine has 3 virtual disk: 1 - System, 2 - Database, 3 - Logs.
Is Windows Server Backup correct backup SQL Server with multiple virtual disk ?
Will the integrity of the data be retained after the virtual machine has been restored?

Backup is run with Powershell script:

 $pol = New-WBPolicy
 $VM = Get-WBVirtualMachine | where vmname -like "SQL"     
 Add-WBVirtualMachine -Policy $pol -VirtualMachine $VM
 Add-WBBackupTarget -Policy $pol -Target (New-WBBackupTarget -NetworkPath $uncPathBackup)   
 Set-WBVSSBackupOptions -Policy $pol -VssCopyBackup      
 Start-WBBackup -Policy $pol
