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