/save-all

Forces the server to save all chunks and player data to disk. The flush option ensures data is written synchronously.

Syntax

/save-all [flush]

Name	Type	Required	Description
flush	literal	Optional	If specified, forces all data to be written to disk synchronously before returning.

/save-all

Saves all world data to disk asynchronously.

/save-all flush

Saves all data and waits for the write to complete before continuing.

Using /save-all flush too frequently on a live server, synchronous writes can cause lag spikes.
Assuming saves happen instantly, without flush, the save is asynchronous.

Automatic saves already happen periodically. Use /save-all before backing up the server to ensure data consistency.

Try these commands on Astroworld or host your own server.
