I am willing to spend time on this, but first I want to double-check that I have understood what I need to back up.
My wamp installation is in C:\wamp64, so when you say "local sites", I believe you mean the contents of the folder C:\wamp64\www.
When you say "databases", I believe you mean the contents of C:\wamp64\bin\mysql\mysql\data, which includes several folders end
