Michael, I can't seem to recreate this.  I converted a VM  with the sparse
option to a template and created a linked clone, and then backed up the
linked clone and didn't get this error message.  This is a log of my linked
clone backup:

Is there any pointers you could give me so I can generate the error?  Thank
you.
