 +
 +===== Cause =====
 +<​html>​
 +The message suggests that the corresponding file is currently locked by Windows during the backup operation. Even with Volume Shadow Copy enabled, the <​b>​UsrClass.dat</​b>​ file cannot be backed up if the corresponding operating system account is logged in while the backup job is still running.
 +</​html>​
 +
 +
 +===== Resolution =====
 +To resolve the issue, ensure that the corresponding operating system account is logged off when the backup job is in progress.
