  1. saying invalid input

  2. When I run this:
    ECHO Y | VSSADMIN DELETE SHADOWS /FOR=C: /ALL >>c:\rjcache\vssadmin.txt
    My result is:
    vssadmin 1.1 – Volume Shadow Copy Service administrative command-line tool
    (C) Copyright 2001-2013 Microsoft Corp.

    Do you really want to delete 1 shadow copies (Y/N): [N]? N

  3. I ran into the same issue, for vssadmin you can use the /quiet switch instead of echo y.
