You need to spell it "--fast" (with two hyphens) rather than "-fast".

It looks like the shell is parsing this as "please run the command gzip 
with arguments '-l' and '\\dmz-nas\backup' and with standard input equal 
to 'file:///\\dmz-nas\backup', which is not what you want.  I'd quote 
the file name.
