What a valid Minecraft world upload should contain
The folder you upload should be the actual world folder. For a normal Java world, files such as level.dat should be at the world root, alongside folders such as region, data, advancements, playerdata, or DIM folders depending on the version and world. A common mistake is creating a ZIP that contains one extra wrapper folder, so the server sees MyWorld/MyWorld/level.dat instead of the expected world root.
Before replacing anything, SPUDZWARE verifies the uploaded archive and checks that required world data is present. Large uploads are also checked so an incomplete/truncated upload can be rejected before the existing world is touched.
Before replacing a world
- Stop normal gameplay and make sure no one is actively building.
- Take a fresh backup or download of the current hosted world.
- Check the new ZIP locally: open it and confirm you can see the real world files.
- Only then start the replacement.
Do not use a world replacement as a backup strategy. Replacement is a destructive operation by nature; the backup is what gives you a way back if the new world is wrong.
What “safe stop” means
When SPUDZWARE performs a normal protected stop, it asks Minecraft to flush world data before shutdown. That lowers the chance of losing recent changes compared with abruptly killing Java. The same idea is used before protected resource shutdowns: save first, then stop.
Safe stopping cannot fix corruption that already exists inside the world or a mod that writes invalid data. It also cannot protect against every operating-system, disk, or game bug. That is why a separate backup remains important even when the normal power controls are careful.
Local downloads and Google Drive backups
A local world download is useful before a major change because you control the file directly. SPUDZWARE also supports optional Google Drive backups when Drive is linked to the account. The Drive connection is meant for backup files created or selected through the platform, not broad access to everything in the account.
For important servers, keep more than one generation. If today's world is already damaged, a backup made five minutes later may contain the same damage. A small rotation gives you a choice between “most recent” and “last known good.”
Make a backup immediately before the change. “I backed up last week” is not very helpful if the build you care about was finished yesterday.
Moving from another host or local PC
Stop the old server first so its world files are consistent, then copy the complete world directory. If the old server uses a non-default world name, check its server configuration so you know which folder is actually active. Modded servers may also have dimensions or data created by mods; keep the complete world rather than cherry-picking only the overworld region folder.
After importing, start once and inspect the console. Join at familiar locations and check inventories, ender chests, dimensions, and important builds before deleting the original copy.
If a world does not start
Do not repeatedly overwrite the hosted copy with slightly different ZIPs. Keep the original archive untouched and work from copies. Check whether level.dat is present, whether the ZIP has an extra folder layer, and whether the server version/loader matches the world and mods that created it. If a mod-created dimension is missing because the mod is no longer installed, restoring the world alone may not be enough.
