Thread:Project:Support desk/How to restore a wiki without a backup?

A while ago, my old computer died, killing my localhost wiki along with it. Luckily, I have a backup, but unfortunately it was made about a year before my wiki died (whoops). So here's the thing: my hard drive still works fine, and I've turned it into an external hard drive. Is it possible for me to restore the most recent version of my wiki based on the files in my old HDD? The only thing I'm not really sure about is MySQL. How would I restore those tables?
