Minecraft server gone?

I was building on my minecraft server that i've been working super hard on. Then someone comes in and builds something with a hopper and this purple block and redstone torched isk what it was… And then my server shut down and i can't get back on. I don't know what happened but i worked sooo hard on it and id be so sad if i couldnt get it back… Anyone know how i can play it again?

How can I get my friend onto my Minecraft server while he is at his place?

I created a minecraft server cause LAN mode SUCKS. LAN hasn't worked for a very long time. People on youtube have fixed the issues for different updates, but once minecraft updates that fix doesn't work anymore in you have to find another way to get LAN to work. This isn't about LAN, i'm just ranting cause LAN has always been a pain in the but.
ok so me and my best friend can play on my server at my house but not while he is at his place. Is there some kinda way to fix this? Multiplayer has always been a pain in my but sense the game came out in 2009. I finally figured out how to create a server for me and my two best friends. The whole point in making a server is that not only we can play at my house, but when we're not together hanging out, and still play minecraft at each of our houses. So of coarse they are both "white listed" so they can play at my place, they just can't join my server while at their houses.
