Problem conclusion

• Windows Server 2008/2012:
  The disk witness (sometimes referred to as the "quorum disk")
  is simply a small clustered disk which is in the Cluster
  Available Storage group. This disk is highly-available and can
  failover between nodes.  It is considered part of the Cluster
  Core Resources group, however it is generally hidden from view
  in Failover Cluster Manager since it does not need to be
  interacted with. The disk witness must not contain any other
  user or application data and Microsoft doesn't recommend
  backup of the disk withness or the data on it.
  TSM follows the Microsoft's recommendation and doesn't allow
  to back up the disk witness on Windows Server 2008/2012.
  The error message has been adjusted to reflect this.
  
  Windows Server 2003:
  There were no restrictions on backup of quorum disk.
  TSM has been changed to allow users to back up the quorum disk.
