wbadmin.exe arguments not working?

Hi all,

Trying to copy a mapped network drive to an external hard drive whenever I click Run on the task scheduler. A CMD opens and then closes instantly.

Program/Script:
%windir%\System32\wbadmin.exe

Here's my argument:
start backup -backupTarget: F:\Operations -include: Y:\ -user:bradlyspicer -password:....... -noInheritAcl -vssCopy -quiet PAUSE
