Your Icarus world is the thing you cannot get back if it is lost, so back it up before you change settings, change files or update.
Before you start: stop the server so the backup holds complete files. See How to start, stop, restart and force-stop your server.
Where the world is stored
Saved worlds are called prospects. Each one is a single .json file in Icarus, then Saved, then PlayerData, then DedicatedServer, then Prospects, inside Files. The server settings file, ServerSettings.ini, is in Icarus, then Saved, then Config, then WindowsServer. Most of what is inside Files is large game files installed by the server.
Make a backup
- Open your server in the panel and click Backups in the left menu.
- Click Start backup with Files selected. The backup copies the whole server folder, so the world is included.
- To keep a copy outside PlayNHost, open the ... menu of the backup and choose Download.
The server folder also holds the game's own files, which can be large, so check the size on the Backups page. If it does not fit your backup space, ask support what to leave out. Do not guess an ignore pattern, because a wrong one can leave your world out of the backup. See How to create, download and restore backups for scheduling, locking and limits.
What to make sure is included
Download the whole Prospects folder (Icarus, Saved, PlayerData, DedicatedServer, Prospects). Add ServerSettings.ini if you changed anything in it by hand. The game files themselves do not need backing up, the server downloads them again on its own.
Restore a backup
A restore replaces the current files with the backup, and anything changed since is lost. Take a fresh backup of the current state first if you may want it back.
Choose Restore to server from the backup's ... menu, confirm, and start the server when it finishes.
To bring a world from another computer instead, see How to upload your own Icarus world.
