MACRIUM REFLECT - Event ID: 513 Source: "Microsoft-Windows-CAPI2"

Thanks Mooly and Barman58, extra + for your avatar Barman58, good one, and to the 58, does it have anything to do with the colors Black & Gold?
And, no emoticons either.
Still hit and miss with my backups. Pretty sure it is related toi VSS issues, If I correct them in Macrium prior to a backup, it generally works, but, some dang thing is messing with the shadow copy functiomn and hiding from sfc and DISM.

I found Macrium had issues with VSS but no idea if this would fix your issues or not:
