Cannot Create the Snapshot (code 2409)


A VM backup plan terminates with the following error: A VSS writer has rejected an event with error 0x800423f4, The writer experienced a non-transient error. If the backup process is retried, the error is likely to reoccur.

In the Event Logs, you will find the following eventID: 8229.


This EventID and error means that it's not possible to create a snapshot for the specific Virtual Machine.


To fix this issue, proceed as follows:

  1. Open Hyper-V Manager.
  2. Open Hyper-V host and select virtual machine that produced this error.
  3. Right-click VM, then select Settings -> Management -> Integration services.
  4. Disable Backup (volume checkpoint) Service.
  5. Click OK.

The machine will be in a 'saved' state for a short period of time when you are not using 'Backup (volume checkpoint)' option and the uptime counter could be reset.

To run the backup plan with this option enabled, check eventlog on the Hyper-V host. It will contain warnings/errors related to the particular machine causing the issue.

Follow these steps for every VM that caused the error.
