Support matrix

This topic contains information about the Windows server that Phoenix certifies and supports.

Support levels

Druva categorizes its platform support levels as follows:

  • Certified Platforms: Druva certifies these environments and performs regular verification to ensure the functionalities work as expected.
  • Supported Platforms: The Druva QA team does not test a supported platform with every cloud release. However, the functionality should work as expected. Druva will provide support for such platforms. Druva may not address issues that require time and resources beyond commercial viability.

Certified platforms

Windows Server (64-bit)

(Standard and Enterprise editions)

Microsoft Windows Server 2012

Microsoft Windows Server 2012 R2 

Microsoft Windows Server 2016


  • Phoenix agent interacts with Volume Shadow Copy Service to back up your data. To ensure successful backups, make sure that the Volume Shadow Copy Service is running. 
  • Druva recommends that you use the Microsoft’s native VSS provider. If you are using a third-party VSS provider, you must configure Phoenix agents to recognize this provider. 
  • Ensure that you enable Hyper-V role on the host.
  • Ensure that Phoenix service is running as administrator.
  • Ensure that you set the shadow storage value according to the virtual machine size.
  • Correctly configure SMB shares.  Windows Server VSS Agent Service must be installed on the server that hosts SMB shares.
  • Hyper-V host should have full control on SMB share. For a full list of requirements for SMB3 shares, see
  • Druva recommends that you enable Backup (volume snapshot) under Hyper-V Integration Services. If the Backup (Volume snapshot) is enabled, Phoenix can take a virtual machine backup without interrupting services on the virtual machine. 
    Note: Integration Services are available for virtual machines with Windows guest OS. However, Microsoft provides Integration Services for certain Linux distributions also. For more information, see:

Ports and communication protocols for Phoenix

Phoenix communicates with your hosts to backup and restore data on your hosts. Phoenix talks to your Hyper-V host through ports and protocols that are secure for communication and transition of data.

Phoenix uses Transport Layer Security (TLS) protocol for establishing the connection and initiating communication between Phoenix components and your Hyper-V hosts.

The following diagram depicts the ports and communication protocols that are used by Phoenix for secure connection and communication during the backup and restore operations.
