How do I recover my litecoin?



I use the litecoin core wallet in which I had some Lite stored. It turned out that I formatted the computer and I had to download the litecoin core wallet again, but I have my balance at 0.000000.
I would like to help me how to recover my balance.

I have a previous backup that has the information of my balance but I do not know how to recover it.
