[Question] Hyper-V Reference point creation and RCT RRS feed

  • Question

  • I'm writing a code for backup based on RCT.

    I've found that a reference point should be created for the RCT-based incremental backup.

    However, when I tried to create reference points, I failed in creation of .rct files.


    I've tried to create a reference point using the CreateReferencePoint method of

    the Msvm_VirtualSystemReferecenPointService class with the input parameter:

    inParams["ReferencePointType"] = 1; // RCT based

    But, it did not create .rct file. Instead, a .hrl(Hyper-V Replication Log) file was created.

    I've tried the other parameters, such as 0 (Log base) and 2 (Not in the reference manual).

    The results were "Error code 32773", which looks "Invalid Parameters."


    Please kindly advise me for the troubleshooting.

    Thank you in Advance.

  • Hi ,

    Before I told you our hyper-v forum doesn't focus on this topic, I have consulted with my PowerShell colleague and C++ colleague. The all told me this is not a PowerShell\C++ related question.

    Since I am really not familiar with code and development related question, I would suggest you have this asked in the following forum:

  • Hi ,

    Please understand, our forum mainly focus on troubleshooting hyper-v manager related questions.

    Your question is related to write a code for backup based on RCT, which our hyper-v forum doesn't focus on.

  • Hi Min-Joon Kim,

    Which backup tool did you use? Windows server backup or some third-party backup tools? 

    What's the OS version of your server? Server 2016 or other version? 

    I found something related , this might can answer your question.

    RCT was built-in natively from server 2016. If you are using windows server backup, I would suspect WSB will not create .rct file.

    Here is a similar thread discussed before, you might have a look:

    Resilient Change Tracking

    Many of the cases I've seen is that RCT created by third-party backup software instead of WSB.

    So my suspicion is that even if you modify the parameter to RCT based through parameter, the HRL file will still be created if you are using WSB.

    For your reference:

    VM backup with Hyper-V Changed Block Tracking (CBT)

  • Thank you, Candy Luo.

    Actually, I'm writing some codes to develop such a 3rd party backup solution.

    Thank you for the websites.
