ICACLS Syntax issues with backup / restore

I am doing some testing with Windows Server 2008 R2 with NTFS permissions.  I have a d: (multiple folders and sub-folders) drive with an existing ntfs permissions.  I want to make a backup of the settings using icacls so I can restore when needed.

So, here is what I am doing and the issue:

1.  Open an elevated cmd prompt.

2.  Run "icacls d:\ /save ntfsDdrive.txt /t /c" without the quotes.  No issues.

3.  Run "icacls d:\ /restore ntfsDdrive.txt" without the quotes and I get the following:

d:\D:PAI(A;OICI;FA;;;SY)(A;OICI;FA;;;BA)(A;OICI;0x1200a9;;;S-1-5-21-1229272821-2
025429265-725345543-3701)(A;CI;0x1200a9;;;BU)S:AI: The filename, directory name,
 or volume label syntax is incorrect.
Successfully processed 0 files; Failed processing 1 files

Any assistance is appreciated.
