Failed to take in-guest VSS snapshot COM error

"Failed to finalize guest processing. Error: Failed to take in-guest VSS snapshot COM error: Code: 0x80042308 Failed to take in-guest VSS snapshot COM error: Code: 0x80042308"

Hi Team,

I received the error message above while backing up the Windows Server 2012 virtual machine hosted on Hyper-V host 2022. This error occurs when the application-aware option is enabled; otherwise, there are no issues. Application awareness is necessary because it hosts SQL.

Your prompt help will be greatly appreciated.

Regards,
PK
