what happened to your server is unforgivable and extremely frustrating for everyone.
But i will now give you 4 good reasons to do it again:
1. You had a successful server running once and you can do it again.
2. You learned this lesson and will never forget again to do a backup or simply host on a provider.
3. Your users enjoyed building on your server. They have to start over, no matter if on yours or someone elses
4. Rising world is in alpha stage. And even though Red51 does his best, there will be the moment when old worlds will not work anymore due to some update.
We all don't like to think about this but it can and will happen.
So everyone is aware that his or her builds are not for eternity.
If it helps you... I would volunteer to build on Your new server to get it going again.
Im not a master builder like others but it would be something.
Also i suggest you to do blueprints of buildings every now and then.
Maybe as a reward for contributing to a Community building, road, etc. Or for an especially nice building
