# Backup ends with "DW9700 - Creation of Application consistent snapshot failed" error

## Issue

> Backup (or replication) process finishes with **"DW9700 - Creation of Application consistent snapshot failed"** error message.

***

## Cause

The error **“DW9700 - Creation of Application consistent snapshot failed”** usually means that during backup (or replication) process the **Xopero** system tried to create a **VSS** snapshot with application consistency, but the process didn’t complete successfully.

***

## Resolution

1. Check whether integration services are enabled in your virtual machine settings (**Services** > **Backup (volume shadow copy)** must be checked).

2. Check whether the operating system is supported by **Hyper-V**:
   1. [Supported **Windows** guest operating systems for **Hyper-V** on **Windows Server** and **Azure Stack HCI**](https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/supported-windows-guest-operating-systems-for-hyper-v-on-windows)
   2. [Supported **Linux** and **FreeBSD** virtual machines for **Hyper-V** on **Windows Server** and **Windows**](https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/supported-linux-and-freebsd-virtual-machines-for-hyper-v-on-windows)
3. Check if integration services are running on the guest system:
