VSS_E_PROVIDER_VETO

VSS_E_PROVIDER_VETO means that a shadow copy provider rejected the requested operation with an expected provider error. VSS does not have enough information to explain the storage-specific reason.

How to investigate

  • Read the System and Application event logs at the same timestamp; the provider is expected to log the underlying reason.
  • Identify whether the selected provider is the Windows system provider or a storage-vendor provider.
  • Check provider prerequisites such as supported volume layout, free capacity, hardware state, and provider configuration.
