It's not so easy. Especially if you don't have experience with it.
I would like to explain but it would take a lot of time to make it working. Also, all other players will need to install this mod to be able to join the server. The mod itself is really useful and i would always recommend to use it to save your buildings as a blueprint and keep it for future uses. However, as I said, it is not easy and is time consuming so maybe it is better to restore from backup if you are making backup regularly. I did it only once with a lot of help from my friend, not sure if i could do it again properly.
Maybe some other kind soul could offer assistance.
