I DO have a working backup. I had to reimport the worlds, but the worlds are all still there and now that they are imported again they work as warps and whatnot. Everything should be back in order and I have the files for it.
There is however, a problem. I will no longer be able to host the server. I am willing to give all of the files over to someone else if they can host it on their pc or on a server hosting somewhere. I certainly want to keep the server up for you guys if you enjoy it, but I just can't afford the electricity and website costs anymore, especially since I don't play. I have had it up for nearly a year now without being a minecraft player, and it is unfortunately the end for me. The total size of the server is about 8GB, but compressed its about 3.5GB.
If you want to host the server, all you need to do is go to my google drive or dropbox (will link on the bottom) and download the file. Then extract it with winrar, winzip, 7zip or a similar program (should be able to just double click it to open and extract if on windows). If on windows, once the files are extracted you just have to double click the start.bat file and the server will run. To let other's connect, you just need to forward the mc port (25565) to your computer's local ip address, (which you can find by opening the command prompt and typing ipconfig, then hitting enter. Your local ip is the one that says ipv4 address, and will usually start with 192.168.). Once you forward that port to that ip in your router, give your players your public ip (which can be found my going to whatsmyip.org) and they just need to type that in to connect.
To op yourself, type op yourusername in the console cmd window that comes up when you run start.bat. You can then control permissions and everything else, but you will have to learn that stuff on your own. Lastly, if you want a domain name, like mymcserver.com, you have to go to a company like godaddy.com that sells domain names and buy one for about $10 for the year. In their control panel you can change where the domain points (the company support team can help you if you are lost), and just point it to your public ip. Then your players can just type in the friendly .com name. Enjin also does free websites, or paid ones. If you do decide to use an enjin site, I would appreciate it if you used the enjin ad on my site to sign up, which will help keep this site running. If you do, I will link to your site as a new home for the server. You will have to mess with the enjin plugin to get whitelisting and promoting to work, or just remove the plugin and do it manually, however you want to do it.
I will edit this post when the uploads to dropbox and google drive have completed. Expect a few hour wait time.
