Hello

Thank you for your question and reaching out. I can understand you are having query related to Event 513 CAPI2.

This event log entry has no impact on VSS backups and can be disregarded

As per below Microsoft article this event log entry can be safely ignored. To prevent this entry from being logged, grant the required permission to the Microsoft Link-Layer Discovery Protocol driver (Mslldp.dll) to process System Writer.
