Quiesced Checkpoint of a Hyper-V VM Cannot Be Created

Product Version: 10.5
Last Modified: 23 November 2021

Problem

The following error message appears:

Quiesced (application-aware) checkpoint of this VM cannot be created.

• NAKIVO Backup & Replication injects a runtime VSS Driver into the VM.
• NAKIVO Backup & Replication requests the VSS Driver to create a quiesced checkpoint.
• VSS Driver uses VSS inside a Windows VM to freeze I/O requests of applications inside the OS.
• If OS quiescing fails to create an application-consistent checkpoint, NAKIVO Backup & Replication displays this error.

Hyper-V 2016 and 2019

Hyper-V 2016 and 2019 has an implementation of VSS, so the VSS is used for the application-aware mode.

Possible Cause

The error may be caused by:

Hyper-V 2012

• Credentials: 
  
  • Incorrect credentials to the VM
  • Insufficient level of permissions
• VM access:
  
  • Incorrect Windows firewall configuration inside the VM
• Integration services:
  • Integration services are not configured properly
• Windows updates:
  • Not all necessary updates were installed

Hyper-V 2016 and 2019

• Incorrect VM OS configuration 

Solution

Hyper-V 2012

1. Credentials. Make sure that:
   • You are using the right credentials for the VM.
   • The credentials you are using have administrative permissions.
2. VM access. Make sure that:
   • Windows firewall allows access to TCP port 9446 from the Director.
3. Integration services. Check if they are up and running.
4. Windows updates: Make sure all the necessary Windows updates were installed.

Hyper-V 2016 and 2019

Make sure that the requirements for the application-aware mode are met.
