 There are a number of things to note after restoring a VM:
 
 - Extensions present during the backup configuration are installed, but not enabled. If you see an issue, reinstall the extensions.
-- If the backed-up VM had a static IP address, the restored VM will have a dynamic IP address to avoid conflict. You can [add a static IP address to the restored VM](/previous-versions/azure/virtual-network/virtual-networks-reserved-private-ip#how-to-add-a-static-internal-ip-to-an-existing-vm).

 - A restored VM doesn't have an availability set. If you use the restore disk option, then you can [specify an availability set](../virtual-machines/windows/tutorial-availability-sets.md) when you create a VM from the disk using the provided template or PowerShell.
 - If you use a cloud-init-based Linux distribution, such as Ubuntu, for security reasons the password is blocked after the restore. Use the VMAccess extension on the restored VM to [reset the password](../virtual-machines/linux/reset-password.md). We recommend using SSH keys on these distributions, so you don't need to reset the password after the restore.
 - If you are unable to access VM once restored due to VM having broken relationship with domain controller, then follow the steps below to bring up the VM:

+- **Windows VMs:** For Windows VMs, the Backup service coordinates with VSS to take an app-consistent snapshot of the VM disks.  By default, Azure Backup takes a full VSS backup (it truncates the logs of application such as SQL Server at the time of backup to get application level consistent backup).  If you are using a SQL Server database on Azure VM backup, then you can modify the setting to take a VSS Copy backup (to preserve logs). For more information, see [this article](https://docs.microsoft.com/azure/backup/backup-azure-vms-troubleshoot#troubleshoot-vm-snapshot-issues).
 
 - **Linux VMs:** To take app-consistent snapshots of Linux VMs, use the Linux pre-script and post-script framework to write your own custom scripts to ensure consistency.

 Yes. You can throttle the rate at which the backup policy runs to minimize the impact on a SQL Server instance. To change the setting:
 
 1. On the SQL Server instance, in the *C:\Program Files\Azure Workload Backup\bin* folder, create the *ExtensionSettingsOverrides.json* file.
 2. In the *ExtensionSettingsOverrides.json* file, change the **DefaultBackupTasksThreshold** setting to a lower value (for example, 5). <br>
