The server has around 10-20 players, 50 peak. In just a month the size of the server (world) went up with 250GB. Is it possible, or is it something else?
Theoretically a chunk should only take up about ~1.2MB (150*16*16*256) and if that's the case, it can't be the world? Is Minecraft world saving just badly optimized?
EDIT: To clarify, I'm not the owner and can't verify it's specifically the world, but the server runs on paper and has a few plugins.
EDIT 2: Fixed calculation
