How do I get back my old LEET server?

#1
So I had a leet server a few years ago and it was running for a while longer but nobody played on it. I wanted to see if it still existed and it does, with all the same plugins, player ranks, etc. when I joined it however, every map and all that other stuff was gone. Is there any way I can get my map data back?
(Lol this server was insanely old, it was on MCPE 1.7)
