I have a desktop Win11 PC and two 1TB SSD’s. Can I just copy one to the other as a fail safe backup?

Normally Win would just setup a backup option for you, but it appears they removed that option for some reason?

I have over 700GB of storage on my main drive so the “get your first X amount of gigs free on one drive” or whatever BS seems like a no go…

I’d like to copy everything -I think its called a “snapshot”?- Something I could just snap into a new motherboard and go on like nothing happened.

Explain like I am 5 but also old enough to have used a fax machine, Ask Jeeves, AIM instant messenger, and Netscape Navigator.
