Abstract
A virtual tape emulator (VTE) that performs data integrity read back verification at host sync points. The VTE first flushes data that it may have buffered to a backend storage subsystem such as a disk array. The VTE then reads all data that was written to the backend storage array between a prior sync point and the current sync point. During this feedback verification, integrity checks can be performed. An error detected during read back verification is returned to the host operation that triggered the sync operation.
