Server files

If you are a rust server owner, you can download the files of a world and back them up? Am I correct?

U mean, to download a files from other server then upload on your own server?

Yes if u know the guy who is a server owner, cos he need to let u download his files.

yes server hosts can backup the save state of the world, but if the procgen stuff gets altered in the update, the same seed may be a different map.
