Event Viewer Warnings from Acronis VM Backups- VSS writer has rejected an event with error 0x800423f4

Thread needs solution

Getting consistent errors performing my Hyper-V VM backups.  Every day I get the following warning:  A VSS writer has rejected an event with error 0x, The writer experienced a non-transient error....

I have found multiple discussions on VSS errors, but not specific to this one.

I have tried the Acronis VSS Doctor and all items passed except the Event Log diagnostic:  The error message returned for that section is shown below.

I also referenced the Acronis article titled : Acronis Backup: VSS Troubleshooting Guide" and will be attempting the Diskshadow troubleshooting steps if a 'chkdsk /f /r c:' does not resolve my issue.

Any other thoughts????

Thanks,

Ray L.

Hello Ray,

welcome to Acronis forums!

Could you please share the full error (including the error description) to check what VSS writer is affected? A full VSS Doctor log will spread more lights on this issue.

Please also let me know if the error appears on the Hyper-V host server or inside the virtual machine.

I would also ask you sharing here an activity log where this error arises (Overview -> Activities, select the respective log, Show details, Download log).
