How do I temporarily stop My Passport 2 TB from backing up?

Someone here told me how to get Back Up and Discovery and I thank most hardily that person for that. But I need to STOP backing up as not to crash it.

Tanx !

Hello,

I stopped Back Up Microsoft Management Console report "The required plug-in failed to reinstall. Should I ?..
How do I create the plug-in.
Is this a sign that MY Passport is damaged ? Can I safely erase and re-install ?
Backup creates 289 GB on My Passport when it Back Up’s. Can I delete File History safely ? How do I change that ?

Help ! Thank you jolhoss
