ImportSnapshots Method in Windows Server 2008 R2 Fails with 0x800423f9 VSS_E_MISSING_HIDDEN_VOLUME Error

When calling the ImportSnapshots method in Microsoft Windows Server 2008 R2 to import shadow copy created by the hardware provider, the 0x800423f9 VSS_E_MISSING_HIDDEN_VOLUME error occurs and the import fails.


When importing a shadow copy using the ImportSnapshots method, an enumeration process for storage devices is performed to recognize the device to be utilized to import shadow copy. Because the enumeration will targets all devices connected to the adapter that is classified as GUID_DEVINTERFACE_STORAGEPORT, it will also process the devices not used to import the shadow copy. It may take some time to perform enumeration processing when enumerating low speed devices and if processing is not completed within 60 seconds (the timeout value for enumerating devices for the volume shadow copy service), the import fails.


When enumeration takes time due to temporary factors, try backing up again. You can also try removing low speed devices from the system.
