SYMPTOMS
Volume Shadow Copy Service (VSS) writers may time out during the backup process and cause the backup to fail. Additionally, you may find the following error message as the status of the backup process:

FAILED_AT_FREEZE (0x800423f2 - VSS_E_WRITERERROR_TIMEOUT)



CAUSE
During snapshot creation, the freeze event suspends all program write activity for data consistency. For example, an SQL database must be in freeze mode for snapshot creation. The thaw event releases the program after successful snapshot creation. The snapshot creation process takes less than 60 seconds.

When the freeze event is called, a worker thread is created to issue a time-out after 60 seconds. If the thaw event is not called within 60 seconds, the worker thread issues a time-out.

This problem occurs if the thaw event is called before the worker thread is started. The worker thread issues a time-out after the thaw event is called and causes the VSS writer to fail.
