Dumb Question - Change From "wake For Back Setting..."

Hi,

I have a computer that I did not select to "automatically wake for backup" - where is the option to turn that back on?

Also - I assumed the back up would start whenever the PC started normally.  This does not seem to be happening.

I thought it would be easy to find in the dashboard -

Also do most people prefer the wake scenario or the backup when it is on (if it works as advertised)?

Thanks
