I'm not even sure mirroring an SSD with a conventional hard drive is even possible, I'd ask in the hard drive forum.
oohhh forget my suggestion as i didnt even read the OP properly sorry.
use some back up software to run automagically.
If its MS then use synctoy

You can set up task scheduler to run it in the background
it will sync a copy of whatever data you ask it to but it will not be able to make a ghost of a drive. its just a simple back up utility.
