ok, well we just had a storm so i shutdown the server along with my computer, the problem, is that when i started my server back up it erased everything, how do i fix this?
Hard to say without knowing what caused it to get erased.... The one thing that would fix it regardless would be to restore a backup, but that assumes that you had a backup method in place before this happened. Which I'm guessing you didn't, if you're posting here...
WHS v1? Or Vail? Version 1 if you had duplication on you would have a backup. Vail, use shadow copies. But either way, you need to have your own backup solution in place. A usb stick, external hdd, cloud, whatever. something you can copy your minecraft data, folder, map, etc to. At some time interval.
