+This article describes how to create application-consistent backups for Azure-deployed Linux VMs using Azure Backup. It covers configuring the script framework and troubleshooting.
 
-When you take backup snapshots of VMs, application consistency means your applications start when the VMs boot after being restored. As you can imagine, application consistency is extremely important. To ensure your Linux VMs are application consistent, you can use the Linux prescript and post-script framework to take application-consistent backups. The prescript and post-script framework supports Azure Resource Manager-deployed Linux virtual machines. Scripts for application consistency don't support Service Manager-deployed virtual machines or Windows virtual machines.
+When Azure Backup takes snapshot of a VM, application consistency ensures that applications start correctly after VM restoration. To achieve this, use the Linux prescript and post-script framework, which supports Azure Resource Manager-deployed Linux VMs. However, these scripts don't work for Service Manager-deployed or Windows VMs.

+## How the framework works?
 
 The framework provides an option to run custom prescripts and post-scripts while you're taking VM snapshots. Prescripts run just before you take the VM snapshot, and post-scripts run immediately after you take the VM snapshot. Prescripts and post-scripts provide the flexibility to control your application and environment, while you're taking VM snapshots.

 Make sure you add appropriate logging while writing your prescript and post-script, and review your script logs to fix any script issues. If you still have problems running scripts, refer to the following table for more information.
